Description

A convenient-to-use flip-open cover assembly Technical Field

The present application relates to a packaging container, and in particular to an easy-to-use flip-open lid assembly.

Background Art

At present, in flip-top bottle caps, in order to facilitate opening, a wrench protruding outward is provided on the flip cap. When opening, the wrench needs to be pried upward to open the bottle cap. On the one hand, a large opening force is required, which is inconvenient to use; on the other hand, the mold structure of the protruding wrench is relatively complex, which increases the difficulty of injection molding and leads to a high manufacturing cost of the bottle cap.

In addition, the applicant submitted a patent application on May 25, 2023, with application number 2023212962416, entitled A beverage bottle cap with a pull-open structure, the rebuttal piece of which extends downward, and there is no wrench part and rebuttal piece extending outward on the bottle cap. The technical solution is provided with a circumferential folding groove on the plate, and the part below the folding groove is the handle part. When opening, the handle part is folded outward along the folding groove, and then the handle part is lifted upward to break the tear line and open. In the subsequent actual testing process, the applicant found that because the handle part is small and can only be pinched by two fingers, it takes a lot of force to break the tear line, and it is inconvenient to open the bottle cap.

Therefore, this application is studied and proposed with respect to the above-mentioned problems.

DETAILED DESCRIPTION

The implementation methods of the present application are described in detail below with reference to Figures 1-14.

Embodiment 1, 3:

As shown in Figures 1-7 and 10-14, the present application discloses an easy-to-use flip-open lid assembly, comprising a lid seat 1 for connecting to the mouth of a container 100, the lid seat 1 being flipably connected to a flip cover 2 for opening or closing the mouth of the container 100 via a connecting piece 11, the flip cover 2 being provided with an opening plate 21 extending toward one side of the lid seat 1 and flippable relative to the flip cover 2 on a side away from the connecting piece 11, the opening plate 21 being provided with a top-opening structure 3 for causing the opening plate 21 to flip outward relative to the flip cover 2 when the lid assembly moves relative to the mouth of the container 100; preferably, the lid assembly is connected to the mouth of the container 100 by threads, the opening plate 21 being provided with a top-opening structure 3 for causing the opening plate 21 to flip outward relative to the flip cover 2 when the lid assembly rotates upward relative to the mouth of the container 100. When it is necessary to operate the flip cover to flip open the container mouth, the user operates the lid assembly to rotate upward relative to the container mouth, so that the top opening structure acts to flip the opening plate outward relative to the flip cover, that is, an operating space is formed between the opening plate and the flip cover for the user's hand to enter to operate the opening plate. Then the user operates the opening plate to cause the flip cover to flip relative to the cover seat to open the container mouth. Therefore, the present application has the characteristics of convenient operation, easy opening, labor saving and low cost.

When the cover assembly is rotated upward relative to the container mouth until it can no longer move upward, on the one hand, the sealing plug is partially or completely disengaged from the container mouth (if the container contains a gas beverage, it may start to leak air), and on the other hand, the plate thread section 31 and the top opening protrusion 32 are disengaged from the external thread of the container mouth and are not affected by the external thread. In this way, when opening the flip cover, the opening plate 21 is almost free of resistance, and it is relatively easy for consumers to open the opening plate 21 and tear off the flip cover.

Among them, when the cover assembly on the mouth of the container 100 is screwed down, the upper side of the screw thread inside the cover assembly contacts the lower side of the screw thread outside the mouth of the container 100. Because the screw thread is inclined, the screw thread of the cover assembly will be gradually squeezed down by the screw thread of the mouth of the container 100, causing the cover assembly to screw down; in addition, when the cover assembly is screwed down, the lower side of the screw thread inside the cover assembly is disengaged from the upper side of the screw thread outside the mouth of the container 100, that is, there is a gap.

When the cap assembly covered on the mouth of the container 100 needs to be unscrewed from the mouth of the container 100, the bottom of the screw thread inside the cap assembly contacts the top of the screw thread outside the mouth of the container 100. Since the screw thread is inclined, the screw thread of the cap assembly will be gradually pushed up by the screw thread of the mouth of the container 100, causing upward rotation. In addition, when the cap assembly is screwed upward, the top of the screw thread inside the cap assembly is disengaged from the bottom of the screw thread outside the mouth of the container 100, that is, there is a gap.

In order to reduce the number of assembly steps and the cost of mold making, the cover base 1, the connector 11 and the flip cover 2 are integrally injection molded from materials such as plastic. The flip cover 2 and the cover base 1 are connected by a breakable or tearable connecting tear line with an opening, which can be an intermittent cut or a thin-walled portion; the connecting tear line can be set on the inside of the cover assembly or on the outside of the cover assembly. When the cover is opened for the first time, the connecting tear line is torn or broken, and the portion of the connecting tear line opening forms the connecting member 11.

As shown in Figures 11-14, two pairs of axial tearing portions 41 are provided at the opening of the connecting tear line 4. The connecting piece 11 is formed by the tearing portion 41 breaking. In this embodiment, four tearing portions 41 are provided, two on the left and two at the back. After the four tearing portions 41 are broken, two connecting pieces 11 are formed. A breaking portion 42 is provided between the cover base 1 and the flip cover 2 between the two connecting pieces to facilitate rotating opening.

As shown in FIGS. 11-14 , the opening plate 21 and the flip cover 2 are an integral structure formed in one piece.

As shown in Figures 1-7 and 11-14, in order to better push open the opening plate, the push-open structure 3 includes a plate thread section 31 provided on the inner wall of the opening plate 21, and the plate thread section 31 is provided with a push-open protrusion 32 for pushing and overlapping with the external thread 110 on the mouth of the container 100 when the cover assembly is rotated upward relative to the mouth of the container 100 to act on the opening plate 21 to flip outward relative to the flip cover 2. During transportation or movement, the blocking cooperation between the push-open protrusion and the external thread 110 can prevent the internal thread of the cover assembly from loosening due to bumps, ensuring that the cover assembly is in place before the consumer drinks, and will not loosen or even be opened. The push-open structure 3 of the flip cover 2 in this application is the same as the push-open structure 3 of the opening plate 21, and will not be repeated here.

As shown in Figures 5 and 7, the upper surface of the plate thread segment 31 is lower than the upper surface of the internal thread 20 of the cover assembly. In this way, when the cover assembly is screwed onto the container mouth, the plate thread segment will not be pushed by the external thread of the container mouth and will not be subjected to force, thereby preventing the opening lever from being pushed open during assembly.

As shown in Figures 5 and 7, the upper inner surface of the plate thread segment 31 is flat, which can facilitate the plate thread segment of the opening plate to overlap on the external thread of the container mouth to prevent the cover assembly from slipping and also better push open the opening plate.

In order to provide another embodiment of the push-opening structure to facilitate the push-opening, the push-opening structure 3 is a push-opening protrusion provided on the flip cover 2 and/or the opening plate 21 and used to cooperate with the container protrusion at the mouth of the container 100. When the operating cover assembly moves relative to the mouth of the container 100, the push-opening protrusion is pushed or abutted against the container protrusion to cause the opening plate to flip outward relative to the flip cover.

As shown in Figures 11-14, the inner side of the cover seat 1 is provided with a locking protrusion for locking into the limiting groove of the mouth of the container 100. Among them, the cover seat 1 can be provided with threads or not; if the cover seat 1 is not provided with threads, the cover seat 1 will not move upward when the cover assembly is rotated; if the cover seat 1 is provided with threads, the locking protrusion is blocked by the limiting groove and will not move upward or will only move upward a very small distance. When the cover assembly is rotated during opening, the locking protrusion of the cover seat is blocked by the corresponding side wall of the limiting groove of the mouth of the container 100, and will not move upward or will only move upward a very small distance, and the threaded section (internal thread) of the flip cover interacts with the external thread of the mouth of the container so that the flip cover moves upward a large distance, resulting in the connection tear line 4 breaking from the middle part, and under the restraining force of the opening part of the connection tear line 4, the flip cover forms an opening plate that opens outward at the part where the connection tear line breaks, and then the opening plate can be pushed upward to open the flip cover, without the need to set an additional wrench, which reduces the processing difficulty and is also convenient for opening.

As shown in Figure 1, a folding groove 211 is provided between the upper end of the opening plate 21 and the flip cover 2. The opening plate is pried outward from the lower end, and the opening plate is bent along the folding groove 211, and the container is opened. The cross-section of the folding groove 211 is V-shaped, and the angles of the two side surfaces of the folding groove 211 can limit the bending angle of the opening plate 21 along the folding groove 211. The inclination angles of the two side surfaces can be 10-65 degrees. When opened, the plate 21 is bent 20-130 degrees along the folding groove 211.

As shown in FIG. 1 , the flip cover 2 is connected to the cover base 1 via a tearable connection point/thin portion 22 , and/or the opening plate 21 is connected to the flip cover 2 via a tearable connection point/thin portion 22 , which can play an anti-counterfeiting role.

As shown in FIGS. 2 and 3 , in order to improve the sealing performance, a sealing plug 23 is provided inside the flip cover 2 .

Example

The difference between Example 2 and Example 1 is that, as shown in Figures 8 and 9, the sealing plug 23 is provided with an avoidance slope 231 on one side corresponding to the opening plate 21, and the avoidance slope 231 facilitates the sealing plug 23 to be inserted into or detached from the container mouth.

As shown in Figs. 8 and 9, a guide portion 232 is provided on the side of the sealing plug 23 away from the opening plate 21. When the flip cover is flipped nearly 90 degrees, the end of the guide portion 232 is already located above the container mouth. When the flip cover is flipped further, the guide portion 232 first slides into the container mouth, ensuring that it is not easy to be misplaced when the flip cover is closed. Only one of the avoidance slope 231 and the guide portion 232 can be provided, or both can be provided for better effect.
