Description

Beverage container with straw

technical field

The present invention relates to a straw-attached beverage container equipped with a straw for inhaling beverages.

Background technique

Heretofore, drink containers with straws that are supposed to be used by infants or the like have been known to the public. Such a beverage container is provided with a straw cover that hides the straw in a bent state so that the straw exposed to the outside is closed when not in use. If the straw cover is opened during use, the blocking of the straw will be released, so the user can use the straw to drink the drink contained in the container.

However, when a hot beverage such as boiling water whose temperature is higher than the outside air temperature is stored in the container, the internal pressure of the sealed container increases. Therefore, when the straw cap is opened, the drink may be sprayed out from the straw which is unblocked at the same time as the opening. Therefore, generally, a drinking container with a straw is provided with an on-off valve for releasing the internal pressure to the outside.

For example, as a beverage container with a straw provided with such an on-off valve, there is known a beverage container (Patent Document 1) in which a locking member for keeping the straw lid in a closed state and an air filter provided on the container The valve body of the on-off valve that opens and closes the hole is integrated, and when the lock of the straw cap is released by operating the lock member, the air hole can be opened by the valve body to release the internal pressure.

The problem to be solved by the invention

Although the beverage container of Patent Document 1 can release the internal pressure by operating the lock member for releasing the lock of the straw cap, when closing the once opened air hole, it is necessary to open the straw cap again in the state where the straw cap is opened. Operate the locking part. That is, after the straw cover is opened and the beverage can be consumed, the user is forced to operate the locking member for closing the air hole. Therefore, the operation of the lock member may become troublesome for the user. In addition, if the user forgets to operate the lock member after the straw lid is opened, the air hole will remain open, so the drink may leak from the air hole when the beverage container is used tilted.

In addition, the beverage container of Patent Document 1 can close the air hole by operating the lock member again with the straw cap opened after releasing the internal pressure by releasing the lock of the straw cap. However, in summer, when the outside air temperature is high, if the straw cover is opened and the air hole is kept closed, there is a problem that the beverage will leak from the straw due to the expansion of the air in the container. In order to avoid such a problem, in the beverage container disclosed in Patent Document 1, it is necessary to operate the lock member to open the air hole while the straw lid is opened. In addition, when the straw cover is closed and the use is stopped, it is necessary to operate the lock member again to close the air hole. When using the beverage container disclosed in Patent Document 1 in which beverage leakage is prevented in this way, the operation of the lock member may become troublesome for the user.

Therefore, an object of the present invention is to provide a drinking container with a straw that can prevent a user from feeling troublesome in handling.

method used to solve the problem

A first beverage container with a straw according to the present invention includes: a container body having an opening; A drinking straw is attached to the straw connector, and the straw-attached beverage container is provided with a straw cover capable of moving between a closed position for hiding the straw and an open position for exposing the straw. The state is installed on the straw joint; the locking member can move between the locking position for locking the straw cover in the closed position and the unlocking position for releasing the lock; the opening A closing valve capable of changing state between a closed state that seals the inside and outside of the container main body and an open state that communicates the inside and outside of the container main body, and is switched from the closed state to the open state by receiving a predetermined operation state transition, and return from the open state to the closed state by releasing the predetermined operation; a transmission member, which acts as a response to the action of the lock member from the lock position toward the release position The predetermined operation of the on-off valve is transmitted, and the straw cap is separated from the on-off valve in a state where the straw cap is located at the open position to release the predetermined operation on the on-off valve.

According to this beverage container, the on-off valve is shifted from the closed state to the open state by the movement of the lock member from the locked position toward the released position, and since the predetermined operation is released in the state where the straw cap is in the open position, the opening and closing The valve returns from an open state to a closed state. Therefore, by releasing the lock of the straw cap, the internal pressure can be released, and at the same time, after the straw cap is opened, the opening and closing valve will automatically become a closed state. Therefore, when the straw cap is opened, the internal pressure can be released without the user paying special attention, and after the straw cap is opened, even if the locking member is not operated, the beverage can be prevented from leaking through the opening and closing valve. Thereby, it is possible to prevent the user from feeling troublesome about the operations required for use.

There are no particular limitations on the structure and material of the on-off valve. For example, the on-off valve has a valve body made of an elastic material that can be elastically performed when the pressing operation as the predetermined operation is performed by the transmission member. out of shape. The valve body may be configured to be shifted to the open state by elastic deformation caused by the pressing operation, and to be released from the open state by canceling the elastic deformation caused by the release of the pressing operation. The state returns to the closed state. According to this aspect, even if the on-off valve is not constituted by a plurality of parts, since the open state and closed state can be changed by elastic deformation of the valve body made of elastic material, the number of parts can be easily reduced.

In this aspect, the valve body may have a plate portion that divides the inside and outside of the container body, and a structure that holds the periphery of the plate portion and can withstand the pressing operation. The cylindrical holding portion is integrated, and a slit extending in the same direction as the operation direction of the pressing operation and penetrating in the plate thickness direction is formed on the plate portion. At this time, since the slit is closed when no external force is applied to the valve body, the valve body is maintained in a closed state. out of shape. Since the distance between both ends of the slit is shortened by the deformation of the plate portion, the slit is opened to shift from the closed state to the open state. Since the elastic deformation of the valve body is eliminated when such a pressing operation is released, both the plate portion and the holding portion return to the original state, and the slit is closed to return to the closed state.

Although the shape of the plate portion may be any shape, for example, the plate portion may be formed in a curved shape that is convex toward the inner side of the container main body. At this time, when a pressure difference between the inside of the container body and the atmospheric pressure occurs with the plate as a boundary, a force acting on the valve body deforms the plate in a direction to close the slit. Therefore, when a pressure difference in which the internal pressure is higher than the atmospheric pressure is generated, passage of fluid in a direction from the inside of the container body toward the outside is prevented. Therefore, if the valve body is held in the closed state, it is possible to reliably prevent the beverage from leaking from the container main body to the outside. On the other hand, when there is a pressure difference between the internal side pressure of the container main body lower than the atmospheric pressure with the plate portion as the boundary, that is, when the internal pressure becomes a negative pressure, the valve body will act on the valve body to open the slit. The force that deforms the plate due to the direction. Therefore, when a pressure difference in which the internal pressure is lower than the atmospheric pressure is generated, passage of the fluid in the direction from the outside to the inside of the container main body can be allowed. Therefore, although the internal pressure may become a negative pressure when the amount of beverage inside the container main body decreases as the beverage is sucked in through the straw, in this case, if the magnitude of the negative pressure exceeds the limit at which the slit is opened , external air will also enter the container main body through the valve body. Therefore, since the user who sucks the beverage through the straw is not required to use a large suction force, the burden on the user can be reduced.

When the valve body is made of an elastic material, the suction pipe may have a suction port made of the same material as the valve body, and the suction port and the valve body are integrated. . In this case, the mouthpiece can be easily elastically deformed when the straw cap is closed. Furthermore, since the suction port and the valve body are integrated, the number of parts can be reduced.

In one aspect of the first beverage container of the present invention, the straw cap may be rotatably attached to the straw joint via a support shaft so that between the closed position and the open position, the locking member is provided on the straw cover in a state capable of moving between the locked position and the released position, and the transmission The member is provided on the lock member in a state capable of moving integrally with the lock member. According to this aspect, by moving the straw cover from the closed position to the open position after the lock member is moved from the locked position to the released position, the lock member and the transmission member move away from the straw joint together with the straw cover. direction of action. Therefore, without providing a special device for separating the transmission member from the on-off valve, the transmission member can be easily separated from the on-off valve by utilizing the movement of the straw cap from the closed position to the open position.

A second beverage container with a straw according to the present invention includes a container body having an opening, and a straw joint attached to the container body so as to close the opening, for sucking into the container body. A straw of a beverage is mounted on the straw connector, and in the beverage container with a straw, a straw cover is provided to be able to move between a closed position for hiding the straw and an open position for exposing the straw It is installed on the suction pipe joint in the state of action; the on-off valve has a valve body made of elastic material, and the elastic material can be elastically deformed when it is pressed, and the valve body is passed by the valve body. The elastic deformation caused by the pressing operation is shifted from the closed state closing the inside and outside of the container body to the communication state connecting the inside and outside of the container body, and the elastic deformation caused by the release of the pressing operation is eliminated. , so as to return from the open state to the closed state; the engaging part, which is arranged on the straw joint or the straw cover in a manner adjacent to the valve body; the operating part, which can be in the first Displacement is carried out between the state and the second state, and the first state is that the operating member engages with the engaging portion when the straw cover is in the open position, so that the valve body can be implemented. In the state of the pressing operation, the second state is that the operating member is in contact with the straw cover during the movement of the straw cover from the open position to the closed position to release the engagement with the engaging part. engagement, so that the state of the pressing operation can be released.

According to this beverage container, since the valve body is made of an elastic material, the elastic deformation of the valve body can be used to change the open state and the closed state even if the on-off valve is not constituted by a plurality of parts, and the number of parts can be easily reduced. In addition, according to this beverage container, by engaging the operation member with the engaging portion in a state where the straw cap is located at the open position, the pressing operation of the valve body is performed by the operation member. Therefore, as long as the operating member is engaged with the engaging portion, the valve body is maintained in the open state. Therefore, even when the outside air temperature rises with the straw lid opened, the internal pressure can be constantly released by communicating the inside and outside of the container body, thereby preventing the beverage from leaking through the straw. Moreover, when the straw cover is moved from the open position to the closed position, since the engagement between the operating member and the engaging portion will be released during the operation, the pressing operation on the valve body will be released, so the valve body will automatically recover. to the closed state. Therefore, it is possible to reliably prevent a situation in which the straw cap is placed in the closed position while the valve body is in the open state. Therefore, even if the user does not pay special attention, only by closing the straw cap, it is possible to prevent the beverage from leaking through the valve body when taking it or the like. As a result, since the chances of requiring the user to perform an operation are reduced compared with the prior art, it is possible to prevent the user from feeling troublesome about the operation.

There are no particular limitations on the structure and material of the operating member. For example, the operating member and the valve body may be made of the same material, or the valve body and the operating member may be integrated. In this case, it is easy to form the valve body and operating parts by the same process, and it contributes to the reduction of the number of parts, so the workload of assembly can be reduced

In one aspect of the beverage container according to the second aspect of the present invention, a configuration may be adopted in which a protrusion protruding upward from the container body so as to be easily lifted by the user is formed on the operation member, and the The protruding portion is lifted, so that the operating member touches the engaging portion, and then engages with the engaging portion, and by moving the straw cover from the open position to the closed position During the process, the protruding part is brought into contact with the straw cap to be pressed down, thereby releasing the engagement between the operation member and the engaging part. According to this aspect, the protruding portion that is easily lifted by the user to engage the operating member and the engaging portion also functions to release the engagement between the operating member and the engaging portion when the straw cap is closed. Therefore, it contributes to the reduction of the number of components compared with the case of separately preparing structures for realizing these various functions.

In one aspect of the beverage container according to the second aspect of the present invention, the valve body may have a plate portion that divides the inside and outside of the container body, and a plate portion that divides the inside and outside of the container body. A cylindrical holding portion capable of receiving the pressing operation is integrated, and is formed on the plate portion, extending in the same direction as the pressing operation direction and penetrating in the thickness direction of the plate. the slit. At this time, since the slit is closed in a state where no external force is applied to the valve body, the valve body will be maintained in a closed state. When a pressing operation is applied to the holding portion of the valve body, the plate portion is deformed according to the pressing operation. Since the distance between both ends of the slit is shortened due to the deformation of the plate portion, the slit is opened to shift from the closed state to the open state. When this pressing operation is released, the slit can be closed and returned to the closed state because the elastic deformation of the valve body will be eliminated and both the plate portion and the holding portion will return to the original state.

Detailed ways

Fig. 1 is a side cross-sectional view showing a part of a beverage container with a straw according to an embodiment of the present invention. Fig. 2 is a top view of the beverage container shown in Fig. 1 . As shown in these figures, a beverage container with a straw (hereinafter referred to as a beverage container) 1 includes a container body 2 having an opening 2a capable of storing beverages, and a container body 2 mounted on the container body 2 so as to close the opening 2a. Straw connector3. In order for the user to easily hold the beverage container 1 , a handle H of a predetermined shape is integrally formed on the container body 2 . A male thread 4 is provided on the upper outer peripheral portion of the container body 2 , and a female thread 5 engaged with the male thread 4 is provided on the inner peripheral portion of the suction pipe joint 3 . The straw adapter 3 is mounted on the container body 2 by being screwed into the container body 2 in a state where the male thread 4 and the female thread 5 are engaged with each other. A straw 6 for sucking a beverage contained in the container body 2 is attached to the straw joint 3 . The straw 6 is configured by connecting a flexible mouthpiece 7 sucked by the user and a main body 8 accommodated in the container main body 2 . The mouthpiece 7 and the main body 8 are made of different materials. The mouthpiece 7 is made of elastically deformable silicone resin, and the main body 8 connected thereto is made of plastic.

Attached to the straw joint 3 is a straw cover 9 operable between a closed position (see FIG. 1 ) for hiding the straw 6 and an open position (see FIG. 7 ) for exposing the straw 6 . The straw cap 9 is rotatably attached to the straw joint 3 via the support shaft 10, so that it can move between a closed position and an open position. The straw cover 9 is provided with a protruding portion 11 for crushing the straw 6 in a bent state at the closed position to make it occluded, and the protruding portion 11 can crush the straw when the straw cover 9 is in the closed position. 6 to protrude below the beverage container 1.

A locking mechanism 15 for locking the straw lid 9 in the closed position is provided on the beverage container 1 . The lock mechanism 15 is provided with: a lock member 16, which can be locked in a lock position (FIG. 1, FIG. 2) to lock the straw lid 9 in the closed position and a release position (FIG. 5A, FIG. 5B) The state of action between is installed on the straw cover 9; the restraint part 17 (Figure 2), which engages the locking part 16 and the straw joint 3 when the locking part 16 is in the locking position; return The spring 18 biases the lock member 16 toward the locked position.

The lock member 16 is slidable in the horizontal direction (the left-right direction in FIG. 1 ) from the locked position to the released position. A part of the lock member 16 is exposed from an opening 9 a formed on the upper surface of the straw cap 9 , and an operation part 19 operable by a user is formed on the exposed part. The constraining part 17 is formed in the shape of a groove extending in the same direction as the lock member 16, and the length of the groove is such that when the lock member 16 reaches the release position, the lock member 16 and the suction pipe joint 3 are released. The length of engagement (see Figure 5A). The return spring 18 is made of silicone resin. When the lock member 16 is operated to the release position by the user and the user releases the lock member, the lock member 16 can return to the lock position by the elastic force of the return spring 18 .

In order to release the internal pressure to the outside, the beverage container 1 is provided with an on-off valve 20 that can communicate with the inside and outside of the container body 2 in a closed state that seals the inside and outside of the container body 2. Change state between the on states of . The on-off valve 20 includes a valve body 21 made of an elastically deformable elastic material. The valve body 21 is attached to the suction pipe joint 3 in a state of sealing the through hole 22 formed in the suction pipe joint 3 . In the beverage container 1 , the valve body 21 is made of the same material as the mouthpiece 7 of the straw 6 , that is, silicone resin, and is integrally formed with the mouthpiece 7 . Since the mouthpiece 7 and the valve body 21 are integrated in the beverage container 1, it is possible to contribute to reduction in the number of parts.

3A and 3B are explanatory diagrams showing enlarged states of the valve body 21 viewed from above, wherein FIG. 3A shows its closed state, and FIG. 3B shows its open state. As shown in FIGS. 3A and 3B , the valve body 21 includes a plate portion 25 that divides the inside and outside of the container body 2 , and a cylindrical holding portion 26 that holds the periphery of the plate portion 25 , and is formed on the plate portion 25 . There are slits 27 penetrating in the plate thickness direction. In the case shown in FIG. 3A , since no external force is applied to the valve body 21 , the slit 27 is closed in an airtight state and maintained in the closed state. As shown in FIG. 3B , when a predetermined operation, that is, a pressing operation is applied to the holding portion 26 of the valve body 21 in the direction indicated by the arrow, the plate portion 25 will elastically deform in accordance with the pressing operation. The slit 27 extends along the operation direction of the pressing operation. Therefore, since the distance X between the two ends of the slit 27 will be shortened compared with the closed state in FIG. 3A by the elastic deformation of the plate portion 25, the slit 27 will be opened in the manner shown in the figure so as to change from the closed state to the open state. state transition. When this pressing operation is released, since the elastic deformation of the valve body 21 will be eliminated so that both the plate portion 25 and the holding portion 26 will return to the original state, the slit 27 will be closed and can return to the closed state in FIG. 3A .

In order to link the pressing operation of the valve body 21 of the on-off valve 20 with the action of the lock member 16 of the lock mechanism 15, as shown in FIG. The movement of the stopper 16 from the locked position to the released position is transmitted to the transmission member 30 of the on-off valve 20 as a pressing operation on the on-off valve 20 . The transmission member 30 is integrated with the locking member 21 , that is to say, the transmission member 30 can move integrally with the locking member 16 .

FIGS. 4A to 6 illustrate the functions of each part of the beverage container 1 during the period from when the lock member 16 is operated to the release position side from the state shown in FIGS. 1 and 2 until the straw cover 9 is opened at the open position. action. 4A and 4B show the state from the start of the operation of the lock member 16 to the period when the engagement of the lock member 16 and the restraint portion 17 is released, wherein FIG. 4A is a top view of this state, and FIG. 4B is the state of the lock member. A cutaway side view of the state. 5A and 5B show the state after the engagement of the locking member 16 and the restricting portion 17 is released, wherein FIG. 5A is a plan view of this state, and FIG. 5B is a side sectional view of this state. Fig. 6 is a side sectional view showing a state in which the straw cap 9 is opened at the open position side.

In the state of FIGS. 1 and 2 where the operation of the locking member 16 has not been implemented, the transfer member 30 is separated from the on-off valve 20 (valve body 21), so that the valve body 21 is in a closed state. 9 is in the closed position so that the straw 6 is blocked, so the container body 2 is sealed. From this state, by starting the operation of the lock member 16 as shown in FIGS. 4A and 4B , the lock member 16 is slightly moved toward the release position side, thereby bringing the transmission member 30 into contact with the holding portion 26 of the valve body 21. , and then the valve body 21 begins to elastically deform. That is, the valve body 21 starts to be pressed by the transmission member 30 , and the slit 27 starts to open. Therefore, the air in the container body 2 starts to flow in the arrow direction through the valve body 21, and the internal pressure of the beverage container 1 starts to decrease.

Then, as shown in FIGS. 5A and 5B , when the locking member 16 moves to the release position, the engagement between the locking portion 16 and the restricting portion 17 will be released, thereby releasing the locking of the straw cap 9 . At the same time, the valve body 21 is further pressed by the transmission member 30, so that the deformation of the valve body 21 is maximized, and as a result, the opening degree of the slit 27 is also maximized. As a result, the internal pressure of the beverage container 1 is completely released in a state where the straw 6 is closed. As shown in FIGS. 5A and 5B , while the lock member 16 is maintained at the release position, the restriction on the straw cap 9 is also released, so the straw cap 9 can be moved from the closed position to the open position.

As shown in FIG. 6 , since the transfer member 30 moving together with the straw cap 9 is separated from the valve body 21 as the straw cap 9 moves to the open position, the pressing operation of the transfer member 30 on the valve body 21 is released. By releasing the pressing operation, the elastic deformation of the valve body 21 disappears and returns to the original state (see FIG. 3A ), and the valve body 21 automatically returns to the closed state. Furthermore, by moving the straw cap 9 to the open position side, the blocking of the straw 6 by the straw cap 9 is released, and the mouthpiece 7 of the straw 6 is straightly extended, so that the straw 6 can be used.

In this manner, according to the beverage container 1 , when the user unlocks the straw cap 9 and opens the straw cap 9 to the open position side, the internal pressure can be reliably released. Moreover, since the on-off valve 20 will automatically return to the closed state when the straw cap 9 is opened so that the straw 6 can be used, the user can prevent the use of the on-off valve 20 without consciously operating the on-off valve 20. When the beverage leaks from the on-off valve 20. Therefore, it is possible to prevent the user from feeling a sense of trouble for operations required for use. In addition, since the transfer member 30 of the beverage container 1 is provided on the lock member 16 in a state capable of moving integrally with the lock member 16 provided on the straw cap 9, even if no function is provided for making the valve body 21. The special device that separates the transmission member 30 for pressing operation from the on-off valve 20 (valve body 21) can also easily connect the transmission member 30 to the on-off valve by utilizing the action of the straw cover 9 from the closed position to the open position. 20 separate.

The opening and closing valve 20 of the beverage container 1 is different from the case of being composed of a plurality of parts, and the open state and the closed state can be changed by utilizing the elastic deformation of the single valve body 21 made of elastic material, so parts can be easily reduced. quantity. In addition, the on-off valve 20 has further features described below.

As shown in FIGS. 1 and 6 , the plate portion 25 of the valve body 21 of the on-off valve 20 is formed into a curved surface, more specifically, a spherical shape that protrudes toward the inside of the container body 2 . Therefore, when a pressure difference in which the internal side pressure of the container main body 2 is higher than the atmospheric pressure occurs with the plate portion 25 as a boundary, the valve body 21 acts to deform the plate portion 25 toward the direction of closing the slit 27. force. Therefore, when such a pressure difference is generated, passage of fluid in a direction from the inside of the container body 2 toward the outside is prevented. Therefore, if the valve body 21 is held in the closed state, it is possible to reliably prevent the beverage from leaking from the container body 2 to the outside. On the other hand, when a pressure difference between the inside of the container main body 2 and the atmospheric pressure occurs with the plate portion 25 as the boundary, that is, when the internal pressure becomes a negative pressure, the valve body 21 will act on the valve body 21, and the direction will be narrowed. A force that deforms the plate portion 25 in the direction in which the slit 27 opens. Therefore, when such a pressure difference occurs, the flow of the fluid in the direction from the outside to the inside of the container body 2 can be allowed. Therefore, although the internal pressure becomes a negative pressure while the amount of beverage inside the container main body 2 is reduced as the beverage is sucked in through the straw 6, in this case, if the magnitude of the negative pressure exceeds the limit at which the slit 27 can be opened , the external air will also enter the container main body 2 through the valve body 21 . Therefore, since the user who inhales the drink through the straw 6 does not require a strong suction force, the burden on the user can be reduced.

In order to prevent beverages from leaking from the straw 6 when the outside air temperature is high, such as in summer, the beverage container 1 is provided with an open state holding mechanism 40 that keeps the on-off valve 20 in an open state when the straw lid 9 is in the open position. . 7 to 9 are explanatory diagrams for explaining the function of the open state holding mechanism 40 . 7 is a partial side sectional view showing a state in which the on-off valve 20 is released from being held in the open state by the open state holding mechanism 40, and FIG. Partial side sectional view of the state in the open state. FIG. 9 is a partial sectional view showing a state in which the straw cap 9 is operated to a closed position from the state shown in FIG. 8 .

As shown in FIG. 7 , the closed state maintaining mechanism 40 includes: an engaging portion 41 provided on the suction pipe joint 3 and an operating member 42, and when the operating member 42 is engaged with the engaging portion 41 and the engagement is released, Accordingly, it is possible to switch between performing the pressing operation on the valve body 21 and releasing the pressing operation. The engaging portion 41 is provided adjacent to the valve body 21 and is configured to protrude toward the valve body 21 side. The operation member 42 is fixed to the outer periphery of the holding portion 26 so as to protrude in a direction facing the engaging portion 41 . The operating member 42 is made of the same elastic material as the valve body 21 and is integrally provided with the valve body 21 . Since the valve body 21 and the operation member 42 are integrated, these parts can be easily formed by the same process, which contributes to the reduction of the number of parts, and thus can reduce the workload of assembly. In addition, a contact portion 42 a protruding upward from the container body 2 and serving as a protruding portion capable of contacting the straw cap 9 is formed on the operation member 42 .

When the user moves the upper left end portion of the tubular holding portion 26 to the left in FIG. 7 with the straw cover 9 at the open position, the operating member 42 is lifted upward by its elasticity. The operation member 42 engages with the engaging portion 41 by touching the engaging portion 41 ( FIG. 8 ). Since the base end portion of the operating member 42 is fixed on the outer periphery of the holding portion 26, when the operating member 42 is lifted upward, the holding portion 26 is deformed in an oblique manner. In other words, when the operating member 42 is engaged with the engaging portion 41 , the pressing operation is applied to the valve body 21 and the operation is maintained. The state of FIG. 8 corresponds to the first state according to the present invention. As clearly shown in FIG. 8, although this pressing operation is an operation opposite to the direction of the operation performed by the above-mentioned transmission member 30, since the pressing operation by the operating member 42 also makes the slit 27 extend in the operating direction, it is different from the operation direction of the operation. The situation shown in FIG. 3B is the same, the slit 27 will be opened so that the valve body 21 is in an open state. As long as the operating member 42 is engaged with the engaging portion 41, the valve body 21 is maintained in the open state, so even when the outside air temperature rises in the state where the straw cover 9 is opened, the inside and outside of the container main body 2 can be checked. The internal pressure is always released through communication, so it is possible to prevent the beverage from leaking through the straw 6 .

If the valve body 21 is maintained in the open state, the straw cap 9 is moved from the open position to the closed position, as shown in FIG. touch, and press down the operating part 42. Thereby, since the engagement between the operation member 42 and the engaging portion 41 is released, the pressing operation by the operation member 42 is released. The state of FIG. 9 corresponds to the second state according to the present invention. Since the elastic deformation of the valve body 21 will be eliminated by releasing the pressing operation, the valve body 21 will return to the original state, so the valve body 21 returns from the open state to the closed state, so that the beverage container 1 is sealed. That is, it is possible to reliably prevent a situation where the straw cap 9 is placed in the closed position with the valve body 21 held in the open state.

Since the beverage container 1 is equipped with the open state maintaining mechanism 40, even if the user does not pay special attention after the valve body 21 is placed in the open state, it is possible to prevent the beverage from passing through the valve body 21 when taking it, just by closing the straw cover 9. The condition of the leak. In this way, compared with the prior art, the chances that the user is required to operate the beverage container 1 are reduced, so that the user can be prevented from feeling troublesome about the operation. Furthermore, although the engaging portion 41 of the open state maintaining mechanism 40 is provided on the straw adapter 3 , the engaging portion 41 may be provided on the straw cap 9 . That is, if the engaging portion 41 is provided on the straw cover 9 in the same position as that in FIG. When the closed position side is operated, the engagement part 41 rotates downward, so that the engagement between the operation member 42 and the engagement part 41 can be released.

The present invention is not limited to the above-described forms, and can be implemented in various forms within the scope of the present invention. The locking member 16 is a member provided on the straw cap 9, and operates by sliding linearly. In addition, the transmission member 30 is provided so as to be able to move integrally with the lock member 16 . However, when implementing the beverage container of the present invention, the installation position and operation mode of the lock member, the structure of the transmission member, etc. can be changed arbitrarily. For example, the present invention can also be implemented by the first to fifth modification examples shown in FIGS. 10 to 14 . In addition, in the description of each of the following modified examples, the configurations having the same functions as those shown in FIGS. 1 to 9 are denoted by the same reference numerals and their descriptions are omitted unless otherwise specified.

FIG. 10 is an explanatory diagram schematically showing a first modified example. As shown in the figure, in the beverage container 1A according to the first modified example, a lock mechanism 15A for locking the straw lid 9A is provided. The locking member 16A is attached to the suction pipe joint 3A in a state of sliding movement between positions. The lock mechanism 15A includes a restraint portion 17A that engages the lock member 16A with the straw cap 9A when the lock member 16A is at the lock position, and a return spring 18A that biases the lock member 16A toward the lock position. A transmission member 30A configured to protrude downward is integrally provided on the lock member 16A. Therefore, in the beverage container 1A, when the lock member 16A is moved in the arrow direction to reach the release position, the transmission member 30A can elastically deform the valve body 21 of the on-off valve 20 . In addition, since the lock member 16A moves to the release position, the restriction on the straw cap 9A is released, so the straw cap 9A can be moved to the open position side. Since the lock member 16A is returned to the illustrated position by the return spring 18A when the straw cap 9A is located on the open position side, the transmission member 30A is separated from the on-off valve 20 . Accordingly, since the pressing operation of the transmission member 30A on the valve body 21 of the on-off valve 20 is released, the on-off valve 20 can automatically return from the open state to the closed state.

FIG. 11 is an explanatory diagram schematically showing a second modified example. As shown in the figure, the beverage container 1B according to the second modified example is provided with a locking mechanism 15B for locking the straw lid 9B. The locking member 16B is attached to the suction pipe joint 3B in a state of rotating between positions. The lock mechanism 15B includes a restricting portion 17B that engages the lock member 16B with the straw cap 9B when the lock member 16B is at the lock position, and a return spring 18B that biases the lock member 16B toward the lock position. A transmission member 30B extending downward from the rotation center portion is integrally provided on the lock member 16B. Therefore, in the beverage container 1B, when the lock member 16B is rotated in the arrow direction to reach the release position, the transmission member 30B can elastically deform the valve body 21 of the on-off valve 20 . Furthermore, since the restraint on the straw cap 9B is released by moving the lock member 16B to the release position, the straw cap 9B can be moved to the open position side. Since the lock member 16B is returned to the illustrated position by the return spring 18B when the straw cap 9B is located on the open position side, the transmission member 30B is separated from the on-off valve 20 . Accordingly, since the pressing operation of the transmission member 30B on the valve body 21 of the on-off valve 20 is released, the on-off valve 20 can automatically return from the open state to the closed state.

FIG. 12 is an explanatory diagram schematically showing a third modified example. As shown in the drawing, a locking mechanism 15C for locking a straw lid 9C is provided on a beverage container 1C according to a third modified example. The locking member 16C is attached to the straw cap 9C in a state of rotating between positions. The lock mechanism 15C includes a restraint portion 17C that engages the lock member 16C with the straw connector 3C when the lock member 16C is at the lock position, and a return spring 18C that biases the lock member 16C toward the lock position. A transmission member 30C extending downward from the rotation center portion is integrally provided on the lock member 16C. Therefore, in the beverage container 1C, when the lock member 16C rotates in the direction of the arrow and reaches the release position, the transmission member 30C can elastically deform the valve body 21 of the on-off valve 20 . Furthermore, since the restraint on the straw cap 9C is released by moving the lock member 16C to the release position, the straw cap 9C can be moved to the open position side. Since the lock member 16C is returned to the initial position by the return spring 18C when the straw cap 9C is located on the open position side, the transmission member 30C is separated from the on-off valve 20 . Accordingly, since the pressing operation of the transmission member 30C on the valve body 21 of the on-off valve 20 is released, the on-off valve 20 automatically returns from the open state to the closed state.

FIG. 13 is an explanatory diagram schematically showing a fourth modified example. This figure shows the state viewed from above. The beverage container 1D according to the fourth modified example is provided with a locking mechanism 15D for locking the straw lid 9D. The locking member included in the locking mechanism 15D The direction of the rotation axis of 16D is different from the second and third modification examples. That is, the direction of the rotation axis of the lock member 16D is set in the vertical direction of the beverage container 1D, and the lock member 16D is attached to the straw joint in a state capable of rotating from the illustrated lock position to the release position. 3D on. The lock mechanism 15D includes a restraint portion 17D that engages the lock member 16D with the straw cap 9D when the lock member 16D is at the lock position, and a return spring 18D that biases the lock member 16D toward the lock position. A transmission member 30D extending rightward from the rotation center portion is integrally provided on the lock member 16D. Therefore, in the beverage container 1D, when the lock member 16D rotates in the arrow direction to reach the release position, the transmission member 30D can elastically deform the valve body 21 of the on-off valve 20 . Furthermore, since the restraint on the straw cap 9D is released by moving the lock member 16D to the release position, the straw cap 9D can be moved to the open position side. Since the lock member 16D is returned to the illustrated position by the return spring 18D when the straw cap 9D is located on the open position side, the transmission member 30D is separated from the on-off valve 20 . Accordingly, since the pressing operation of the transmission member 30D on the valve body 21 of the on-off valve 20 is released, the on-off valve 20 automatically returns from the open state to the closed state. In this modified example, a further modification may be made in such a manner that the lock member 16D is provided on the side of the straw cap 9D.

FIG. 14 is an explanatory diagram schematically showing a fifth modified example. As shown in the figure, the beverage container 1E according to the fifth modified example is provided with a lock mechanism 15E for locking the straw lid 9E. The locking member 16E is attached to the suction pipe joint 3E in a state of sliding movement between positions. The lock mechanism 15E includes a restricting portion 17E that engages the lock member 16E with the straw cap 9E when the lock member 16E is at the lock position, and a return spring 18E that biases the lock member 16E toward the lock position. The on-off valve 20E differs from each of the above examples in that the valve body 21E extends long from the suction pipe joint 3E, and is attached to the lock member 16E so as to be movable integrally with the lock member 16E. Furthermore, a transmission member 30E protruding upward so as to be adjacent to the valve body 21E is provided on the suction pipe joint 8E. Therefore, in the beverage container 1E, when the lock member 16E moves in the direction of the arrow and reaches the release position, since the valve body 21E moves together with the lock member 16E and collides with the transmission member 30E, it will pass through the transmission member 30E. A pressing operation is applied to the valve body 21E to elastically deform the valve body 21E. Furthermore, since the restraint on the straw cap 9E is released by moving the lock member 16E to the release position, the straw cap 9E can be moved to the open position side. When the straw cover 9E is located at the open position side, the lock member 16E is moved upward by the return spring 18E, or by the lock member 16E and the straw cover 9E, thereby separating the transfer member 30E from the on-off valve 20E. . Accordingly, since the pressing operation of the transmission member 30E on the valve body 21E is released, the on-off valve 20E automatically returns from the open state to the closed state.

The opening and closing valves according to the forms shown in FIGS. 1 to 9 and the modified examples shown in FIGS. 10 to 14 have a valve body made of an elastic material, and the closed state is changed by elastic deformation of the valve body. and components in the open state. However, the present invention can also be implemented using an on-off valve having the structure shown in FIG. 15 . Fig. 15 is an explanatory diagram showing another form of the on-off valve. The on-off valve 50 shown in the figure includes a partition 51 that divides the inside and outside of the container body 2, and a movable valve body 52 provided in a state capable of moving in the left-right direction in the figure while being in close contact with the partition 51. , a return spring 53 that urges the movable valve body 52 toward the illustrated position side, and a stopper 54 that restricts the movement of the movable valve body 53 . A through hole 51 a having a size capable of being blocked by the movable valve body 52 is formed in the center of the partition plate 51 . Further, a through hole 52 a having a size larger than the through hole 51 a of the partition plate 51 is formed in the movable valve body 52 .

In the illustrated state, the position of the through hole 51 a of the partition 51 and the position of the through hole 52 a of the movable valve body 52 deviate from each other, and the through hole 51 a of the partition 51 is blocked by the movable valve body 52 . Therefore, the on-off valve 50 is in a state of closing the inside and outside of the container body 2 . When the movable valve body 52 is pressed in the direction of the arrow from the state shown in the figure, since the positions of the through holes 51a and 52a will be consistent, the inside and outside of the container main body 2 will communicate, thereby shifting from the closed state to the open state. . When the pressing operation on the movable valve body 52 is released in the state shifted to the open state, the movable valve body 52 is returned to the illustrated position by the return spring 53 . Therefore, the on-off valve 50 automatically returns from the open state to the closed state simultaneously with release of the pressing operation.

Even if the on-off valves involved in the modes shown in FIGS. 1 to 9 and the modified examples shown in FIGS. 10 to 14 are replaced with the on-off valve 50 shown in FIG. The on-off valve 50 applies a pressing operation as a predetermined operation. Therefore, the beverage container using the on-off valve 50 has functions equivalent to those of the beverage containers of the above-described embodiment and various modified examples.

The predetermined operation to be applied to the on-off valve is appropriately determined according to the structure of the on-off valve. Therefore, for example, in the case of using an on-off valve that transitions from a closed state to an open state by stretching some parts, the stretching operation corresponds to a predetermined operation. Furthermore, in the case of employing an on-off valve that shifts from a closed state to an open state by rotating some parts, the rotating operation corresponds to a predetermined operation.

When using a valve body capable of changing the state between the closed state and the open state by elastic deformation, a valve body having a structure different from that of the illustrated embodiment may be used. In addition, the operating member does not have to be provided integrally with the valve body, and the operating member and the valve body may also be implemented as separate members so that the operating member and the valve body operate independently.
