Description

Airtight tank with one-way exhaust valve

The present invention relates to the technical field related to airtight containers, and more particularly to a container lid equipped with a control assembly to facilitate assembly and disassembly of the lid and the container.

Today's moisture-proof containers can store food while effectively isolating the air inside and outside the container, preventing the food from getting damp. See Republic of China Patent Publication No. M384166 for a moisture-proof container consisting of a container body and a lid. The container body has an open storage space, and the lid seals the container body opening. The walls of the container body and lid located within the storage space are coated with a film made of natural lacquer, allowing the container body and lid to be adjacent to the storage space. The active Laccase enzyme contained in the natural lacquer acts as a medium to continuously dry (harden) the moisture in the storage space, fully absorbing the moisture in the storage space and preventing the food from getting damp.

However, conventional moisture-proof containers are coated with an active Laccase enzyme film on the container body and the inner wall of the lid, which causes food to easily adhere to the film and affect the food quality. Therefore, how to improve the shortcomings of conventional moisture-proof containers is the primary research focus of the present invention.

The present invention is an airtight container with a one-way exhaust valve. Its main purpose is to provide a container with an airtight effect. By pressing the control part of the lid, the lid can be easily opened or closed, thereby achieving the purpose of easy assembly or disassembly.

The present invention is an airtight container with a one-way exhaust valve. Its secondary purpose is to install an elastic exhaust member on the lid to discharge the fermentation gas of the food inside the container out of the container, thereby achieving the purpose of preserving the food.

To achieve the above-mentioned objectives, the present invention provides an airtight container with a one-way exhaust valve, comprising: a container having a storage space; a lid mounted over the container, the lid having an air outlet groove and a control groove, each of which is provided with an air outlet hole and a hole, respectively, that communicate with the container's storage space; an elastic air outlet member elastically abutting the air outlet groove of the lid; and a control assembly having a control member that is elastically displaceable within the control groove of the lid. When the control member is pressed, the control member and the hole in the control groove are opened, thereby communicating with the hole in the control groove and the container's storage space.

The elastic air outlet component has a first connecting portion, and a ring rib and a hook rib are respectively provided on the surface and the end of the first connecting portion. The first connecting portion of the elastic air outlet component is connected to the air outlet hole of the air outlet groove and is limited by the blocking ring.

The control assembly further has a clamping member and an elastic member, and the control member has a shaft. When the shaft of the control member passes through the elastic member and the clamping member and enters the control groove from the outside of the cover, the clamping member of the shaft seals the hole in the control groove.

The control member has a notch on its shaft surface. When pressed, the control member pushes against the elastic member, and the control member's shaft protrudes from the hole in the control groove toward the inside of the lid, causing the clamping member in the hole in the control groove to open, allowing external gas to pass through the notch on the control member's shaft, through the hole in the control groove, and into the storage space of the container, thereby forming a connected state.

Among them, the elastic air outlet part is arranged on the air outlet groove and is limited by the blocking ring, and the elastic air outlet part extends outward from the first connecting part to form a second joint surface. The second joint surface is arranged corresponding to the first joint surface of the air outlet groove and a sticking part is protruded near the position of the first connecting part. The surface of the first connecting part has a ring rib and a hook rib is protruded at the end.

The top of the lid also has an air extraction groove, which is provided with an air extraction hole connected to the storage space of the container, and a concave rib is protruded upward at the outer edge of the air extraction groove.

Among them, it further includes an exhaust assembly, which has an exhaust member. The exhaust member is arranged in the exhaust groove of the cover and has a pressing part. The side wall of the pressing part is recessed with an annular groove, the top is protruding with a pull block, and the bottom is recessed with an air flow groove. In addition, a plurality of notches connected to the annular groove are opened near the outer end edge of the pressing part.

The vacuum assembly also has an elastic positioning ring, which is slidably arranged in the annular groove of the compression part. When the vacuum component is pulled upward or pushed downward, the elastic positioning component can move up and down in the annular groove of the compression part.

Among them, the vacuum assembly also has an elastic leak-stopping part, and the elastic leak-stopping part has a second connecting part protruding from the position of the vacuum hole of the vacuum groove. The elastic leak-stopping part is connected to the vacuum hole of the vacuum groove through the second connecting part, and a block is protruding from the air flow groove part of the pressing part, and the block is set on top of the elastic leak-stopping part.

Among them, the exhaust assembly also has a fixing part, which is hollow and has a convex rib corresponding to the concave rib of the exhaust groove. The convex rib of the fixing part and the concave rib of the exhaust groove are mutually locked to prevent the exhaust part from accidentally falling off the exhaust groove during operation.

In order to clearly illustrate the above-mentioned objectives and effects of the present invention, the following embodiments of the present invention are described in detail with reference to the accompanying diagrams. First, please refer to Figures 1 to 8, which show an airtight container with a one-way exhaust valve, including:

A container 1 has an open storage space 10 and a joint portion 11 on the top, and the storage space 10 is used to place food.

A lid 2 is tightly and slidably mounted on the joint 11 of the container 1. The lid 2 has a vent groove 20 and a control groove 21. The vent groove 20 is located at the top of the lid 2 and has a vent hole 200 and a first joint surface 201 extending outward from the vent hole 200. The vent hole 200 passes through the lid 2 and connects to the storage space 10 of the container 1. A stopper ring 202 is protruding upward from the outer edge of the first joint surface 201. The control groove 21 is located on the side of the lid 2 and has a hole 210 that passes through the lid 2 and connects to the storage space 10 of the container 1.

An elastic air outlet part 3 has a first connecting portion 30 protruding therefrom and a second joint surface 31 extending outward from the first connecting portion 30. The surface of the first connecting portion 30 has an annular rib 300 with adjacent concave and convex portions and a hook rib 301 at the end. The second joint surface 31 of the first connecting portion 30 is arranged corresponding to the first joint surface 201 of the air outlet groove 20, and a sticking portion 310 is protrudingly provided around the second joint surface 31 adjacent to the first connecting portion 30. When the elastic air outlet component 3 is arranged in the air outlet groove 20, it can be stably placed in the air outlet groove 20 due to the limitation of the stop ring 202 of the air outlet groove 20, and when the first connecting portion 30 of the elastic air outlet component 3 is connected to the air outlet hole 200 of the air outlet groove 20, a part of the area of the sticking portion 310 of the second joint surface 31 will be pressed against the air outlet hole 200, and the annular rib portion 300 and the hook rib portion 301 of the first connecting portion 30 make the elastic air outlet component 3 more closely attached to the air outlet groove 20.

A control assembly 4 has a control member 40, a pressing member 41 and an elastic member 42.

The control member 40 is integrally formed with a shaft portion 400 . The shaft portion 400 has a receiving portion 401 and a hole 402 on its surface. The receiving portion 401 receives the pressing member 41 .

The clamping member 41 penetrates the hole 210 of the control groove 21 from the inside of the lid 2. When the shaft 400 of the control member 40 passes through the elastic member 42 and enters the control groove 21 from the outside of the lid 2, the clamping member 41 is pressed against the hole 210 of the control groove 21, thereby sealing the hole 210. At this point, the hole 210 of the control groove 21 is no longer connected to the storage space 10 of the container 1, making the storage space 10 of the container 1 airtight and moisture-proof. In this embodiment, the elastic member 42 is a telescopic spring.

Furthermore, the use of the airtight container with a one-way exhaust valve of the present invention is described.

Please refer to Figures 7 and 8 . To remove the lid 2, simply press the control member 40 of the pressure control assembly 4, causing it to push against the elastic member 42, compressing it. The shaft 400 of the control member 40 then protrudes from the hole 210 of the control groove 21 toward the inside of the lid 2, disengaging the pressing member 41 of the shaft 400 from the hole 210 of the control groove 21. This opens the hole 210 and connects it to the storage space 10 of the container 1. At this point, external air enters the storage space 10 of the container 1 through the notch 402 of the shaft 400 of the control member 40, passes through the hole 210 of the control groove 21, and is then removed.

On the other hand, when the lid 2 is to be placed on the container 1, the control member 40 of the control assembly 4 is also pressed. Similarly, because the external gas can pass through the notch 402 of the shaft 400 of the control member 40 and pass through the hole 210 of the control groove 21, a connection is formed with the storage space 10 of the container 1, so that the lid 2 can be easily placed on the joint 11 of the container 1. When the control member 40 is released, the elastic member 42 of the control member 40 rebounds, causing the pressing member 41 of the shaft 400 of the control member 40 to press against the hole 21 of the control groove 21. External gas cannot communicate with the storage space 10 of the container 1. Under the principle of atmospheric pressure, the lid 2 is tightly mounted on the container 1 and cannot be removed, making the storage space 10 of the container 1 airtight and moisture-proof.

Furthermore, when the pressure of the food fermentation gas in the storage space 10 of the container 1 increases, the gas in the storage space 10 of the container 1 will be discharged outward through an air gap D between the elastic air outlet member 3 and the air outlet groove 20 (as shown in Figure 5), and the food will not be deteriorated due to excessive air pressure in the storage space 10 of the container 1.

In summary, the airtight container with a one-way exhaust valve of the present invention can easily be assembled or disassembled between the lid 2 and the container 1 by pressing or releasing the control member 40 of the control assembly 4. Moreover, when the pressure of the food fermentation gas in the storage space 10 of the container 1 increases, it can be discharged outward through the air gap D between the elastic exhaust member 3 and the exhaust groove 20, thereby achieving the purpose of preserving the food.

The above is only used to explain the preferred embodiments of the present invention and is not intended to limit the present invention in any form. Therefore, any modifications or changes made to the present invention under the same spirit of the invention, which are other forms that can be implemented and have the same effect, should still be included in the scope of protection intended by the present invention.
