Description

Technical Field

[0001] This utility model belongs to the field of packaging container technology, and specifically relates to an exhaust packaging container. Background Technology

[0002] Currently, there are various types of packaging containers on the market, most of which have only one discharge channel. The wide variety of daily chemical products contains countless substances, each with its own unique characteristics, requiring suitable packaging containers to be matched to these characteristics. For example, some contents themselves produce gas, or the contents may decompose into gases when moving from a low-temperature to a high-temperature environment, or the air may expand when moving from a low-altitude to a high-altitude region. These situations can cause the gas inside the packaging container to expand, creating additional pressure on the flexible tube and potentially damaging it. To solve these problems, containers can be made using packaging materials with higher pressure resistance and flexibility, or reinforcing ribs can be added to the inside and outside of the container to prevent deformation or breakage during gas expansion, but the results are not ideal. Therefore, there is an urgent need to design a packaging container that can expel air or gases released from the decomposed contents without opening the container, allowing it to adapt to a wider range of environmental changes. Utility Model Content

[0003] To overcome the shortcomings and disadvantages of existing technologies, the purpose of this utility model is to provide a venting packaging container. This venting packaging container has a venting function, which can release air or gases decomposed from the packaging container without opening the container.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A venting packaging container includes a cap, a container body, and a venting structure. The cap is detachably connected to the container body, and the venting structure is disposed within the container body. The venting structure includes a pipe head support, a pipe fitting, a one-way valve support, and a one-way valve venting assembly. The pipe head support is detachably connected to the pipe fitting, the pipe fitting is detachably connected to the one-way valve support, and the one-way valve support is detachably connected to the one-way valve venting assembly.

[0006] Preferably, the one-way valve venting assembly is fixedly assembled from a one-way valve component and a waterproof and breathable membrane.

[0007] Preferably, the one-way valve component includes a one-way valve spring and a one-way valve body. The one-way valve spring is disposed in the one-way valve body. The bottom of the one-way valve spring is an arc surface, and channels are provided around the arc surface.

[0008] Preferably, the one-way valve spring is made of an elastic material.

[0009] Preferably, the cap has a sealing structure, a positioning structure, and a connecting structure inside. The sealing structure is located at the center, and the positioning structure is located outside the sealing structure. The positioning structure has a notch, which is used to prevent the positioning structure from sealing. The inner wall of the connecting structure has multiple internal threads. The container body includes a container outlet and a container material cavity. The container outlet has multiple external threads on its outside, and the external threads of the container material cavity mate with the internal threads of the positioning structure.

[0010] Preferably, the tube head support has a dual-channel structure, and the tube head support is snapped into the outlet of the container. The tube head support includes a first channel and a second channel. The liquid in the container is squeezed out through the first channel, and the air in the container is discharged through the second channel.

[0011] Preferably, the one-way valve support includes a pipe fitting connector and a one-way valve support body, and the one-way valve support is connected to the pipe fitting through the pipe fitting connector.

[0012] Preferably, the waterproof and breathable membrane is a membrane that allows air to pass through but not liquids.

[0013] The exhaust packaging container of this invention has a dual-channel structure, with one channel for material extrusion and the other for venting gas from the container. When properly sealed, if excess air is generated due to environmental factors or the contents, the container becomes pressurized, allowing the excess air to escape through the internal exhaust channel. To prevent air exchange, a one-way valve is installed inside. This device allows air to escape from the container while preventing external air from entering, thus avoiding contamination of the contents.

Detailed Implementation

[0037] The present invention will be further described in detail below with reference to specific embodiments, but the implementation of the present invention is not limited thereto. All materials used in the embodiments of the present invention can be purchased commercially.

[0038] Example

[0039] like Figures 1 to 2 As shown, the exhaust packaging container of this utility model includes a cap 1, a container body 2, and an exhaust structure. The cap 1 is detachably connected to the container body 2, and the exhaust structure is disposed inside the container body 2. The exhaust structure includes a pipe head support 3, a pipe fitting 4, a one-way valve support 5, and a one-way valve venting assembly 6. The pipe head support 3 is detachably connected to the pipe fitting 4, the pipe fitting 4 is detachably connected to the one-way valve support 5, and the one-way valve support 5 is detachably connected to the one-way valve venting assembly 6.

[0040] like Figure 3 As shown, the cap 1 is provided with a sealing structure 11, a positioning structure 12 and a connecting structure 13 inside. The sealing structure 11 is located in the center position, and the positioning structure 12 is located outside the sealing structure 11. The positioning structure 12 is provided with a notch, the purpose of which is to prevent the positioning structure 12 from sealing. The inner wall of the connecting structure 13 is provided with multiple internal threads, and a notch is provided on one side of the internal threads, the purpose of which is to prevent the positioning structure 12 from sealing.

[0041] like Figure 4 As shown, the container body 2 includes a container outlet 21 and a container material cavity 22. The container outlet 21 has multiple external threads on its exterior, and the external threads of the container material cavity 22 are engaged with the internal threads of the positioning structure 12.

[0042] like Figures 5 to 8 As shown, the tube head support 3 has a dual-channel structure. The tube head support 3 is snapped into the discharge port 21 of the container. The tube head support 3 includes a first channel 31 and a second channel 32. The liquid in the container is squeezed out through the first channel 31, and the air in the container is discharged through the second channel 32.

[0043] When the cap 1, container body 2, and exhaust structure are assembled as follows: Figure 20 As shown, when the lid is locked, the discharge sealing structure 11 seals with the first channel 31 to prevent material overflow. At this time, there is a gap between the notched positioning structure 12 and the second channel 32, and the positioning structure 12 can still vent normally. Simultaneously, the positioning structure 12 can also hold the container in place to prevent the lid from rubbing against the container, thus preventing product defects and other adverse factors.

[0044] like Figures 9 to 10 As shown, the pipe fitting 4 is a hollow round pipe.

[0045] like Figures 11 to 13 As shown, the one-way valve bracket 5 includes a pipe connector 51 and a one-way valve bracket body 52. ​​The one-way valve bracket 5 is connected to the pipe 4 through the pipe connector 51.

[0046] like Figures 14 to 15 As shown, the one-way valve component 61 includes a one-way valve spring 611 and a one-way valve body 612. The one-way valve spring 611 is disposed inside the one-way valve body 612. The bottom of the one-way valve spring 611 is an arc surface, and circular holes are provided on both sides of the arc surface. Channels 613 are provided around the periphery of the arc surface. The one-way valve spring 611 is made of a material that can elastically deform.

[0047] The one-way valve component 61 described in this utility model is essentially a one-way check valve. This one-way valve component 61 allows fluid and air to pass through in only one direction. The directions of fluid and air passage within the one-way valve component 61 are as follows: Figure 15 As shown. When the top surface of the arc is subjected to force, the top surface of the arc will be pushed backward, and the channel 613 will open; when the inside of the arc is subjected to force, the top surface of the arc will be forced against the bottom of the circular hole, and the channel 613 will be disconnected. At this time, the one-way valve component 61 can pass through water-like fluid or fluid of a certain viscosity and air in the working state.

[0048] like Figures 16 to 17 As shown, the one-way valve venting assembly 6 is assembled from a one-way valve component 61 and a waterproof and breathable membrane 62. The waterproof and breathable membrane 62 is fixed to the one-way valve component 61 via a hot-pressing process. In this invention, the waterproof and breathable membrane 62 is a membrane that allows only air to pass through and not liquids. Combined with the one-way valve component 61, the one-way venting assembly 6 forms a structure that allows only one-way air passage. Air passes through the one-way venting assembly 6 and exits via the second channel 32 of the pipe head support 3 through the pipe fitting 4.

[0049] like Figures 18 to 19As shown, the exhaust structure is assembled from a pipe head bracket 3, a pipe fitting 4, a one-way valve bracket 5, and a one-way valve venting assembly 6. The pipe head bracket 3 and the pipe fitting 4 are detachably connected, the pipe fitting 4 and the one-way valve bracket 5 are detachably connected (one end of the pipe fitting 4 is connected to the second channel 32, and the other end of the pipe fitting 4 is connected to the one-way valve bracket 5), and the one-way valve bracket 5 and the one-way valve venting assembly 6 are detachably connected.

[0050] like Figure 20 As shown, the exhaust packaging container of this utility model, before use, involves squeezing the container body 2 to expel the air inside the container, opening the cap 1, and allowing the material in the container's material chamber 22 to flow out. This exhaust packaging container can effectively expel the gas inside the container, which is beneficial for material extrusion, reduces material residue inside the container, and avoids waste.

[0051] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
