Description

Technical Field

[0001] This utility model relates to the field of food preservation, and in particular to a food container venting connector and a food container venting plug structure. Background Technology

[0002] After consuming food stored in containers, people typically reseal the containers to prevent them from becoming damp or spoiling prematurely. To ensure that the vacuum within the container is not disrupted each time food is removed, patent CN220549485U discloses a food container evacuation device and a food preservation apparatus. However, this patent uses a sealing plug and a soft rubber sleeve, where the soft rubber sleeve includes an elastic expansion sleeve that expands upon gas injection. Because the elastic expansion sleeve needs to completely fill the container after expansion, the material's elasticity is crucial, leading to high production costs. If used as a disposable consumable, the usage cost is also high. Furthermore, if the soft rubber sleeve is reused, the sealing plug and soft rubber sleeve must be disassembled each time the food is removed from the container, requiring cleaning and sterilization, which is cumbersome. Utility Model Content

[0003] The purpose of this invention is to provide a food container venting connector and a food container venting plug structure. The structure is simple, the production cost is low, and it can be used as a disposable consumable, making it more convenient to use.

[0004] To achieve the above objectives, this utility model provides a food container venting connector, including a connector body, which has a drain channel and an air inlet channel. The input end of the drain channel is provided with a suction tube connected thereto, and the output end of the air inlet channel is provided with a soft film sealing bag that can be rolled up or folded and is connected thereto. The soft film sealing bag is connected to the connector body. The suction tube passes through the middle of the inner cavity of the soft film sealing bag or is located on the outside of the soft film sealing bag.

[0005] As a further improvement of this utility model, the connector body includes a connector and an embedded part connected to each other. The connector, the embedded part, and the output end of the suction tube are arranged in sequence. The drainage channel passes through the middle of the connector and the embedded part in sequence, and the air inlet channel passes through the embedded part. The input end of the air inlet channel and the connector are both located on the same side of the embedded part, and the input end of the drainage channel and the output end of the air inlet channel are both located on the other side of the embedded part.

[0006] As a further improvement of this utility model, the suction tube passes through the middle of the inner cavity of the soft film sealing bag, and the output end of the suction tube extends to the outside of the soft film sealing bag.

[0007] As a further improvement of this utility model, one side of the embedded part is connected to a cylindrical part and a first extension part. The drain channel passes through the connector, the embedded part, and the first extension part in sequence. The first extension part is connected to the suction tube. The cylindrical part is located outside the first extension part and a channel is left between the two. The soft film sealing bag is provided with a first bag opening and a second bag opening. The edge of the first bag opening is sealed to the cylindrical part, and the edge of the second bag opening is sealed to the outer wall of the suction tube. The output end of the air inlet channel, the channel, and the inner cavity of the soft film sealing bag are connected in sequence.

[0008] As a further improvement of this utility model, the liquid suction tube is located on the outside of the soft film sealing bag, and the two are arranged side by side.

[0009] As a further improvement of this utility model, one side of the embedded part is connected to a first extension and a second extension arranged in parallel.

The air inlet and liquid outlet of the connector body are both located at one end of the sealing plug body, while the inlet of the suction tube and the body of the soft film sealing bag both extend from the other end of the sealing plug body.

[0011] Beneficial effects

[0012] Compared with the prior art, the advantages of the food container venting connector and the food container venting plug structure of this utility model are as follows:

[0013] 1. By using a flexible film sealing bag instead of an elastic expansion sleeve, the flexible film sealing bag, being sheet-like before use due to the absence of air inside, can be rolled up or folded, taking up little space. This makes it convenient for personnel to insert the suction tube and the rolled-up or folded flexible film sealing bag into containers containing liquid food. When gas is injected into the flexible film sealing bag through the air inlet channel using an air pump, or when liquid is drawn out of the container through the liquid outlet channel using a liquid pump, the originally rolled-up or folded flexible film sealing bag gradually unfolds and expands. Even if the flexible film sealing bag lacks elasticity, it can gradually fill the space inside the container through expansion, preventing air from entering. Its structure is simple, its production cost is low, and it can be used as a disposable consumable, making it more convenient to use.

[0014] 2. In use, the sealing plug body is inserted into the container opening and a seal is formed by the conical elastic sleeve. The connector body of the food container venting connector has a detachable plug-in seal with the middle of the sealing plug body. The air inlet and liquid outlet of the connector body are both located at the end of the sealing plug body facing outwards from the container. The inlet of the suction tube and the body of the soft film sealing bag both protrude from the other end of the sealing plug body and are located inside the container. After the liquid food in the food container has been mostly emptied, the food container, sealing plug, and food container venting connector do not need to be disassembled and can be discarded directly.

[0025] Embodiments of the present invention will now be described with reference to the accompanying drawings.

[0026] Example 1

[0027] The specific embodiments of this utility model are as follows: Figures 1 to 6 As shown, a food container venting connector includes a connector body 1, which has a drain channel 11 and an air inlet channel 12. The drain channel 11 and the air inlet channel 12 can be parallel or non-parallel. The inlet end of the drain channel 11 is connected to a suction tube 2, and the outlet end of the air inlet channel 12 is connected to a rollable or foldable soft film sealing bag 4, which is attached to the connector body 1. The soft film sealing bag 4 can be made of various materials such as plastic or aluminum foil, and can be rolled into a cylindrical shape or folded into multiple layers to ensure that it can be inserted into the container cavity through the opening after being removed from the product packaging.

[0028] The connector body 1 includes a connector 13 and an insert 17 connected together. Both the connector 13 and the insert 17 are cylindrical and arranged coaxially. The connector 13, the insert 17, and the output end of the suction tube 2 are arranged sequentially. The drain channel 11 passes through the middle of both the connector 13 and the insert 17, and the air inlet channel 12 passes through the insert 17. The input end of the air inlet channel 12 and the connector 13 are both located on the upper side of the insert 17, and the input end of the drain channel 11 and the output end of the air inlet channel 12 are both located on the lower side of the insert 17.

[0029] The suction tube 2 passes through the middle of the inner cavity of the soft film sealed bag 4, and the output end of the suction tube 2 extends to the outside of the soft film sealed bag 4.

[0030] The lower side of the embedded part 17 is connected to the cylindrical part 16 and the first extension part 15. The drainage channel 11 passes through the connector 13, the embedded part 17, and the first extension part 15 from top to bottom. The lower end of the first extension part 15 is connected to the suction tube 2. The cylindrical part 16 is located outside the first extension part 15, and a gap is left between the two to form a channel 121. The soft film sealing bag 4 has a first bag opening 41 and a second bag opening 42. The edge of the first bag opening 41 is fitted onto the outer wall of the cylindrical part 16 and the two are sealed together, which can be done by adhesive bonding. The edge of the second bag opening 42 is sealed to the outer wall of the suction tube 2, which can also be done by occupancy. The output end of the air inlet channel 12, the channel 121, and the inner cavity of the soft film sealing bag 4 are connected in sequence. In this embodiment, the embedded part 17 can be provided with two air inlet channels 12, such as Figure 3 As shown.

[0031] In this embodiment, the lower end of the first extension 15 is also provided with a plug-in part 14, which is plugged into and cooperates with the upper end of the suction tube 2.

[0032] A food container venting plug structure employing a food container venting connector further includes a sealing plug 5, which comprises a sealing plug body 51 extending through the center. A tapered elastic portion is provided on the outer side of the sealing plug body 51. In this embodiment, a tapered elastic sleeve 52 is fitted over the sealing plug body 51, and the tapered elastic sleeve 52 may be made of silicone material. Alternatively, the sealing plug body 51 and the tapered elastic portion can be integrally molded, both being made of elastic material. The connector body 1 of the food container venting connector and the center of the sealing plug body 51 are detachably plugged in and sealed. The inlet end of the air inlet channel 12 and the outlet end of the drain channel 11 of the connector body 1 are both located at one end of the sealing plug body 51, while the inlet end of the suction tube 2 and the body of the soft film sealing bag 4 both extend from the other end of the sealing plug body 51.

[0033] Specifically, the sealing plug body 51 has a relief cavity 511, a countersunk hole 512, and a through hole 513 connected sequentially from its upper end to its lower end in the middle. The insert 17 of the connector body 1 is inserted downward into the countersunk hole 512, and the two can form a seal through a sealing ring or by interference fit. The connector 13 is located in the relief cavity 511, and the input end of the suction tube 2 and the body of the soft film sealing bag 4 both protrude from the lower end of the through hole 513 of the sealing plug body 51.

[0034] In use, the sealing plug body 51 is inserted downwards into the mouth of the wine bottle 3, and a seal is formed between the two through the conical elastic sleeve 52. The connector body 1 of the food container venting connector is detachably plugged into the middle of the sealing plug body 51 for a sealed fit. The inlet end of the air inlet channel 12 and the outlet end of the drain channel 13 of the connector body 1 are both located at the end of the sealing plug body facing the mouth of the wine bottle 3. The inlet end (lower end) of the suction tube 2 and the body of the soft film sealing bag both extend from the other end of the sealing plug body and are located inside the wine bottle 3, with the lower end of the suction tube 2 close to the bottom of the inner cavity of the wine bottle 3. When you wish to drink the red wine, insert the inlet of the vacuum pump (not shown in the diagram, but its principle is the same as CN220549485U) into connector 13 of the connector body 1. A seal can be formed between the two via a sealing ring or by an interference fit. Start the vacuum pump; the vacuum pump uses negative pressure to draw the red wine from the bottle 3 through the suction tube 2 and the drainage channel 11, and out through connector 13. As the red wine is drawn out of the bottle 3, atmospheric pressure draws outside air into the soft film sealing bag 4 through the air inlet channel 12, causing the originally rolled-up or folded soft film sealing bag 4 to unfold and expand, gradually filling the inner cavity of the bottle 3. Once the red wine in the bottle 3 is essentially emptied, the bottle 3, sealing plug 5, and food container emptying connector do not need to be disassembled and can be discarded directly.

[0035] Alternatively, the sealing plug 5 can be omitted, and the food container venting connector can be used independently. Simply insert the insert 17 of the connector body 1 into the opening of the food container (e.g., the mouth of a wine bottle 3), and ensure a seal between the two through a sealing ring or interference fit.

[0036] Example 2

[0037] like Figure 7 , Figure 8 As shown, the difference from Example 1 is that the suction tube 2 is located outside the soft film sealing bag 4, and the two are arranged side by side.

[0038] Both connector 13 and insert 17 are cylindrical and coaxially arranged. The centerline of drain channel 11 is parallel to and offset from the axis of connector 13. The centerline of air intake channel 12 is parallel to and offset from the axis of connector 13. A notch 131 is provided on the side wall of connector 13, located near insert 17. The input end of air intake channel 12 is located inside notch 131. Figure 8 As shown.

[0039] The lower side of the insert 17 is connected to a first extension 15 and a second extension 18 arranged side by side, with a gap between them. The drain channel 11 passes through the connector 13, the insert 17, and the first extension 15 from top to bottom, and the first extension 15 is connected to the suction tube 2. The air inlet channel 12 passes through the insert 17 and the second extension 18 in sequence. The soft film sealing bag 4 is provided with a third bag opening 43, the edge of which is fitted onto the outer wall of the second extension 18 and the two are sealed together, which can be done by adhesive bonding. When the soft film sealing bag 4 is in the rolled-up state, it can be wrapped around the outside of the suction tube 2, enclosing the suction tube 2 in the middle.

[0040] The present invention has been described above in conjunction with the preferred embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations made in accordance with the essence of the present invention.
