Description

Technical Field

[0001] The utility model relates to the technical field of packaging, and particularly relates to a packaging container and an air valve cover thereof. Background Art

[0002] For existing packaging containers, such as drinking water buckets, drinking water bottles, etc., most of them are directly installed on a water dispenser for water intake, and some others are used for pumping water after removing the lid. In addition, some are also equipped with a water tap at the lower side of the packaging container. When in use, the water tap can be directly opened to take water. For such a packaging container, if the water tap is directly opened without opening the lid, affected by air pressure, it is very difficult for water to flow out. If the lid is directly removed, it is easy to cause pollution by dust, flies or the like. Therefore, for a packaging container equipped with a water tap at the lower side, it is difficult to solve the problems of air pressure balance inside the container and dust and insect prevention at the same time. Summary of the Utility Model

[0003] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide an air valve cover, which can solve the problems of air pressure balance inside the packaging container and dust and insect prevention at the same time.

[0004] To solve the above problems, the technical solution adopted by the utility model is as follows: an air valve cover, including a cover body, a valve piece is arranged at the top of the cover body, and part of the edge of the valve piece is detachably connected to the cover body. An inwardly protruding retaining wall is arranged on the inner side of the top of the cover body corresponding to the detachable connection of the valve piece. When the valve piece is pressed, the detachable connection of the valve piece can be disengaged from the cover body inwardly, so as to form an air gap between the valve piece and the retaining wall.

[0005] Compared with the prior art, the beneficial effect of the utility model is that: the air valve cover of the utility model is provided with a valve piece at the top of the cover body. During transportation and storage, the valve piece is not pressed and can be kept connected to the cover body to seal and protect the liquid in the packaging container. When in use, the valve piece is pressed down, and the detachable connection of the valve piece will be disengaged from the cover body inwardly, so that an air gap is formed between the valve piece and the retaining wall. When the water tap on the side of the packaging container is opened, the liquid in the packaging container can flow out under the action of air pressure. The setting of the retaining wall can allow air to enter while opening the air gap, and can limit the width of the air gap not to be too large, which can prevent dust, flies or the like from entering and avoid pollution of the liquid in the packaging container.

[0006] For the above air valve cover, a weak connection is provided between part of the edge of the valve piece and the cover body.

[0007] For the above air valve cover, a resilient block is arranged on the inner side of the top of the cover body. The first end of the resilient block is fixedly connected to the cover body, and the second end is fixedly connected to the valve piece.

[0008] The above valve cover, the first end of the resilient block protrudes more inwardly than the second end.

[0009] The above valve cover, the width of the first end of the resilient block is greater than the width of the second end.

[0010] The above valve cover, a concave pit is provided on the outer side of the top of the cover body, the concave pit is located on one side of the valve piece, when the valve piece is not pressed, the top of the valve piece protrudes outward from the bottom wall of the concave pit and does not exceed the top surface of the cover body.

[0011] The above valve cover, the edge of the concave pit away from the valve piece is arc-shaped.

[0012] The above valve cover, the separable connection part of the valve piece is arc-shaped, and the retaining wall is also arc-shaped accordingly.

[0013] The present utility model also provides a packaging container, including a container body and the above valve cover, and the valve cover is sleeved on the mouth of the container body. Since this packaging container adopts the above valve cover, it at least has all the beneficial effects that the above valve cover can bring.

[0018] Explanation of the reference numerals in the drawings: 100 cover body, 110 retaining wall, 120 concave pit, 200 valve piece, 210 separable connection part, 300 air gap, 400 resilient block. Specific Embodiments

[0019] The following details the embodiments of the present utility model, with reference to Figures 1 to 3, an embodiment of the present utility model provides a valve cover, which includes a cover body 100. A valve piece 200 is provided on the top of the cover body 100. Part of the edge of the valve piece 200 is detachably connected to the cover body 100, and the remaining edge of the valve piece 200 is bendably connected to the cover body 100, which can also be considered as rotatably connected to the cover body 100. For example, a plastic material can be used so that the remaining edge of the valve piece 200 can be bent or rotated with the cover body 100, but will not fall off the cover body 100. An inwardly protruding retaining wall 110 is provided on the inner side of the top of the cover body 100 corresponding to the detachable connection portion 210 of the valve piece 200. When the valve piece 200 is pressed, the detachable connection portion 210 of the valve piece 200 can be detached inward from the cover body 100 so that an air gap 300 is formed between the valve piece 200 and the retaining wall 110.

[0020] Referring to Figure 2 , this valve cover is provided with a valve piece 200 on the top of the cover body 100. During transportation and storage, the valve piece 200 is not pressed and can be kept connected to the cover body 100 to seal and protect the liquid in the packaging container. Referring to Figure 3 , when in use, the valve piece 200 is pressed down, and the detachable connection portion 210 of the valve piece 200 will be detached inward from the cover body 100, so that an air gap 300 is formed between the valve piece 200 and the retaining wall 110. When the faucet on the side of the packaging container is opened, the liquid in the packaging container can flow out under the action of air pressure. The setting of the retaining wall 110 can limit the width of the air gap 300 from being too large while allowing the air gap 300 to open for air intake, which can prevent dust, flies, etc. from entering and avoid contamination of the liquid in the packaging container.

[0021] Without the function of the retaining wall 110, when the valve piece 200 is pressed inward and the detachable connection portion 210 is detached inward from the cover body 100, a relatively large side opening will appear between the detachable connection portion 210 and the cover body 100, making it easier for dust or flies to enter the interior of the packaging container from the opening. As Figure 3 shown, the retaining wall 110 is inwardly protruding, acting like a door frame, which can block the side opening so that gas enters the container body through the vertically connected air gap 300. After the side opening is blocked, the width of the air gap 300 is small, which can play a good role in dust and insect prevention while meeting the air intake requirement. Of course, it should be noted that although in Figure 3 , in order to show the thickness of the product structure, the blocked side opening seems not obvious. In the actual product, the thickness of the valve piece 200 is actually small, and the material at the connection with the cover body 100 is thin. Therefore, when the valve piece 200 is pressed inward, its detachable connection portion 210 will easily protrude more inward from the inner side surface of the top of the cover body 100, so a relatively large side opening will inevitably be generated.

[0022] Further, a partial edge of the valve piece 200 and the cover body 100 are in a weak connection, that is, the separable connection part 210 of the valve piece 200 and the cover body 100 are in a weak connection, so as to facilitate breaking through the air inlet with a finger. When there is no obvious external force, the valve piece 200 remains fixedly connected to the lid, playing a role in sealing and protecting the liquid in the packaging container. When in use, it is not necessary to apply much force to press the valve piece 200, and the separable connection part 210 of the valve piece 200 can be separated inward from the cover body 100. Further, a concave pit 120 is formed on the outer side of the top of the cover body 100. The concave pit 120 is located on one side of the valve piece 200. When the valve piece 200 is not pressed, the top of the valve piece 200 protrudes outward from the bottom wall of the concave pit 120, but does not exceed the top surface of the cover body 100. During packaging, transportation and other processes, it can prevent accidental contact with the valve piece 200 and cause the air gap 300 to open. When it is necessary to open the air gap 300, the top of the valve piece 200 protrudes outward from the bottom wall of the concave pit 120, which can also facilitate consumers to apply force to press the valve piece 200. Further, the edge of the concave pit 120 away from the valve piece 200 is arc-shaped, and its shape and size are similar to a finger, so as to facilitate consumers to press with a finger. Further, the separable connection part 210 of the valve piece 200 is arc-shaped, and the retaining wall 110 is also correspondingly arc-shaped. While ensuring the air inlet through the air gap 300 is opened, it can block the side opening from multiple directions, so as to better achieve the dust and insect prevention effect.

[0023] Further, referring to Figure 1 and Figure 2, a resilient block 400 is provided inside the top of the cover body 100. The first end of the resilient block 400 is fixedly connected to the cover body 100, and the second end is fixedly connected to the valve piece 200. When pressing the valve piece 200, since the separable connection 210 needs to be broken, a certain pressing force is required, so the separable connection 210 of the valve piece 200 will sink into the cover body 100 to a certain depth. The setting of the resilient block 400 enables the valve piece 200 to rebound to a certain extent after being pressed open, which can both achieve ventilation and prevent dust and insects. The resilient block 400 can be integrally formed with the valve cover, and the material is the same as that of the cover body 100. The material of the cover body 100 can refer to the lid on the existing drinking water bucket. Since the resilient block 400 has a certain plasticity, when the valve piece 200 is pressed, the second end of the resilient block 400 also moves inward accordingly. Specifically, it bends or rotates around the rest of the edge of the valve piece 200, while the first end of the resilient block 400 is fixedly connected to the cover body 100 without deformation and movement. Since the resilient block 400 has a fixed shape, when the pressing force on the valve piece 200 is released, the resilient block 400 has a tendency to return to its original state. Therefore, the second end of the resilient block 400 will rebound outward to a certain extent, thereby driving the valve piece 200 connected to its second end to rebound. Further, the first end of the resilient block 400 protrudes more inward than the second end, and the width of the first end of the resilient block 400 is greater than the width of the second end. Looking from Figure 1 the top view, it can be seen that the resilient block 400 is trapezoidal. Looking from Figure 2 the longitudinal sectional view, it can be seen that the resilient block 400 is also trapezoidal. The first end of the resilient block 400 is fixedly connected to the cover body 100 and has a larger size, so it also has a greater strength. It can not only prevent the rest of the edge of the valve piece 200 from being crushed, but also has a greater resilience force to ensure that the resilient block 400 can drive the valve piece 200 to rebound.

[0024] An embodiment of the present invention also provides a packaging container, which includes a container body and the above-mentioned valve cover, and the valve cover is sleeved on the mouth of the container body. Since this packaging container adopts the above-mentioned valve cover, it at least has all the beneficial effects that the above-mentioned valve cover can bring. Further, the packaging container can be a drinking water bucket, a drinking water bottle, etc., or other containers for containing liquids equipped with a side faucet.
