[0028] Normally, when people use a product, they open the product container's outlet to use the product. However, during the opening process, air enters the container, which can easily oxidize the product, affecting its freshness and reducing its shelf life.

[0029] To solve the above problems, refer to Figures 1-4 , Figure 1 This diagram illustrates the structure of a discharge assembly according to an embodiment of this application. Figure 2 This diagram shows a structural schematic of the first type of sealing component provided in an embodiment of this application. Figure 3 This diagram illustrates the structure of the second type of sealing element provided in an embodiment of this application. Figure 4 A cross-sectional view of the connector provided in an embodiment of this application is shown.

[0030] This application provides a discharge assembly, which includes a connector 1 and a sealing member 2. The connector 1 is used to connect to the open end of a container and has a communication port 11 communicating with the inner cavity of the container. The connector 1 has an annular stepped portion 12 on the inner wall of the communication port 11, and the stepped portion 12 has an abutment surface 121 on the side facing the open end. The sealing member 2 is located in the communication port 11 and includes a sealing portion 21, an elastic portion 22, and a flow portion 23. The sealing portion 21 is used to seal the open end of the communication port 11, and the flow portion 23 is provided to communicate with the inner cavity of the container. The flow port 231 has a flow section 23 that abuts against the contact surface 121. One end of the elastic part 22 abuts against the sealing part 21 and the other end is used to abut against the flow section 23. In the first state, the elastic part 22 is in the return state, and the sealing part 21 blocks the opening end of the communication port 11 to prevent the inner cavity of the container from communicating with the outside. In the second state, pressure is applied to the sealing part 21, so that the elastic part 22 is in the compressed state, the sealing part 21 is separated from the opening end of the communication port 11, and the opening end of the communication port 11 communicates with the inner cavity of the container through the flow port 231 to make the inner cavity of the container communicate with the outside.

[0031] It is important to understand that connector 1 connects to the open end of the container, and the outer periphery of connector 1 is sealed to the open end of the container to prevent product leakage from the connection point. Connector 1 has a communication port 11, which communicates with the inner cavity of the container. Product can be placed into or removed from the container through the communication port 11. Connector 1 has an annular stepped portion 12 protruding from the inner wall of the communication port 11. The stepped portion 12 is located at the end of connector 1 facing the container, and a contact surface 121 is provided on the side of the stepped portion 12 facing the open end. The contact surface 121 is planar.

[0032] The sealing element 2 is located in the connecting port 11. The sealing element 2 includes a sealing part 21, an elastic part 22, and a flow part 23. The sealing part 21 is used to seal the open end of the connecting port 11. When the sealing part 21 is located at the open end of the connecting port 11, the connecting port 11 is closed. When the sealing part 21 is removed from the open end of the connecting port 11, the connecting port 11 is opened. The flow part 23 is used to abut against the contact surface 121. The flow part 23 is provided with a flow port 231 for connecting to the inner cavity of the container. Multiple flow ports 231 can be provided, such as three, four, or five. This application does not limit the number of flow ports 231. Multiple flow ports 231 are arranged at intervals along the periphery of the flow part 23. The arrangement of multiple flow ports 231 can increase the area communicating with the inner cavity of the container. One end of the elastic part 22 abuts against the sealing part 21 along its length, and the other end of the elastic part 22 abuts against the flow part 23 along its length.

[0033] In the first state, the elastic part 22 is in the returned state, and the sealing part 21 seals the opening end of the communication port 11 to prevent the inner cavity of the container from communicating with the outside world. The container is in a sealed state, reducing the product's contact with air and improving the product's shelf life and freshness.

[0034] In the second state, pressure is applied to the sealing part 21, causing the elastic part 22 to be in a compressed state. The sealing part 21 is separated from the opening end of the connecting port 11, and the opening end of the connecting port 11 is connected to the inner cavity of the container through the flow port 231, so that the inner cavity of the container is connected to the outside world, so as to facilitate adding things to the container and also to facilitate pouring things out of the container.

[0035] This application, through the setting of connector 1 and sealing member 2, connects the connector 1 to the container, and the sealing member 2 allows the product in the container to communicate with the outside world only when it needs to be filled or removed. Otherwise, the container remains sealed, thereby reducing the chance of the product in the container coming into contact with the outside air and improving the product's shelf life and freshness.

[0036] In some optional embodiments, the sealing part 21, the elastic part 22, and the flow part 23 are integrally molded. The materials of the sealing part 21, the elastic part 22, and the flow part 23 can be plastic or other materials. The integral molding of the sealing part 21, the elastic part 22, and the flow part 23, compared to using a separate spring, reduces production costs and facilitates installation. Furthermore, the elastic part 22 is spiral-shaped to facilitate its contraction or return to its original position.

[0037] In some optional embodiments, the elastic part 22 includes a curved part 221 and a connecting ring 222. At least two curved parts 221 are provided and spaced apart circumferentially along the sealing part 21. The connecting ring 222 connects at least two curved parts 221. This application does not limit the number of curved parts 221; it can be two, three, or four. The arrangement of curved parts 221 facilitates the contraction or return of the elastic part 22. The arrangement of at least two curved parts 221 improves the contraction or return effect of the elastic part 22. The connecting ring 222 is located in the middle of the curved part 221. The connecting ring 222 is made of the same material as the curved part 221 and is integrally formed with the curved part 221. The arrangement of the connecting ring 222 improves the stability of the elastic part 22.

[0038] In some optional embodiments, the connector 1 is provided with a guide portion 13 at the open end of the communication port 11. The guide portion 13 is integrally formed with the connector 1. The guide portion 13 is provided with an inner cavity communicating with the communication port 11. The guide portion 13 may be annular. The inner cavity of the guide portion 13 gradually decreases in the direction away from the step portion, so as to reduce the opening of the communication port 11 and facilitate the sealing portion 21 to block the opening of the communication port 11. The diameter of the sealing portion 21 gradually decreases in the direction away from the step portion 12, so as to allow the sealing portion 21 to extend into the open end of the communication port 11. When the sealing portion 21 extends into the inner cavity of the guide portion 13, it can prevent the inner cavity of the container from communicating with the outside. When the sealing portion 21 extends into the inner cavity of the guide portion 13, the guide portion 13 deforms, making the sealing between the sealing portion 21 and the guide portion 13 tighter and improving the sealing effect of the sealing portion 21.

[0039] In some optional embodiments, the inner diameter of the stepped portion 12 gradually decreases in the direction toward the blocking portion 21, and the outer diameter of the flow portion 23 gradually decreases in the direction toward the blocking portion 21. During installation, the blocking member 2 is inserted into the connector 1 from the outlet end. The setting of the inner diameter of the stepped portion 12 and the outer diameter of the flow portion 23 facilitates the installation of the blocking member 2 and the connector 1.

[0040] Reference Figure 1 and Figure 5 , Figure 5 This diagram illustrates the structure of the cover provided in an embodiment of this application. In some optional embodiments, a cover 3 is also included, which covers the connector 1 and is threadedly connected to the connector 1. In a third state, the cover 3 is connected to the connector 1, causing the elastic part 22 to be in a compressed state to prevent the container's inner cavity from communicating with the outside, and the sealing part 21 disengages from the opening end of the communication port 11. The cover 3 is provided to cover the connector 1 and the sealing part 2 to seal the inner cavity of the container. When the cover 3 is connected to the connector 1, the elastic part 22 is in a compressed state, the container is in a sealed state, and the product inside the container is sealed and preserved, improving the product's shelf life and freshness, while also facilitating handling or transportation.

[0041] Reference Figures 3-5 In some optional embodiments, a sealing portion 31 is provided on the side of the cover 3 facing the step portion 12. The sealing portion 31 is used to extend into the communication port 11. The sealing portion 31 is annular, and its wall thickness gradually decreases in the direction towards the step portion 12. The sealing portion 31 is made of the same material as the cover 3, and the sealing portion 31 and the cover 3 are integrally formed. The sealing portion 31 is annular and used to extend into the communication port 11. The provision of the sealing portion 31 can increase the sealing effect between the cover 3 and the sealing member 2. Furthermore, the wall thickness of the sealing portion 31 gradually decreases in the direction towards the sealing member 2, which facilitates the sealing portion 31 extending into the communication port 11 and improves the sealing effect between the sealing portion 31 and the sealing member 2.

[0042] In some optional embodiments, the cover 3 is provided with anti-slip ridges 32 on its periphery. The anti-slip ridges 32 extend along the height direction of the cover 3, and multiple anti-slip ridges 32 are provided and arranged at intervals along the circumference of the cover 3. The anti-slip ridges 32 facilitate the operator in opening the cover and improve the convenience of operation.

[0043] Reference Figures 1-5 This application also includes a packaging material, comprising a container and a dispensing assembly as described in any of the preceding claims. The dispensing assembly includes a connector 1 and a sealing member 2. The connector 1 is used to connect to the open end of the container and has a communication port 11 communicating with the inner cavity of the container. The connector 1 has an annular stepped portion 12 on the inner wall of the communication port 11, and the stepped portion 12 has an abutment surface 121 on the side facing the open end. The sealing member 2 is located in the communication port 11 and includes a sealing portion 21, an elastic portion 22, and a flow portion 23. The sealing portion 21 is used to seal the open end of the communication port 11, and the flow portion 23 has a flow port 231 communicating with the inner cavity of the container. The flow section 23 abuts against the contact surface 121, and one end of the elastic section 22 abuts against the sealing section 21 and the other end is used to abut against the flow section 23. In the first state, the elastic section 22 is in the return state, and the sealing section 21 blocks the opening end of the communication port 11 to prevent the inner cavity of the container from communicating with the outside. In the second state, pressure is applied to the sealing section 21, so that the elastic section 22 is in the compressed state, the sealing section 21 is separated from the opening end of the communication port 11, and the opening end of the communication port 11 communicates with the inner cavity of the container through the flow port 231 to make the inner cavity of the container communicate with the outside.

[0044] This application, through the setting of connector 1 and sealing member 2, connects the connector 1 to the container, and the sealing member 2 allows the product in the container to communicate with the outside world only when it needs to be filled or removed. Otherwise, the container remains sealed, thereby reducing the chance of the product in the container coming into contact with the outside air and improving the product's shelf life and freshness.
