[0031] Figure 5 , Figure 1 This is an exploded view of a discharge device provided in an embodiment of this application. Figure 2 This diagram shows a schematic representation of the discharge device provided in an embodiment of this application in its first state. Figure 3 Show Figure 2 The diagram shows a cross-sectional view of the discharge device along direction AA. Figure 4 This diagram shows a schematic representation of the discharge device provided in an embodiment of this application in a second state. Figure 5 Show Figure 4 The diagram shows a cross-sectional view of the discharge device along direction BB.

[0032] This application provides a discharge device, including 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 111 communicating with the inner cavity of the container. The connector 1 has an annular stepped portion 112 on the inner wall of the communication port 111. The stepped portion 112 has a first abutment surface 1121 and a second abutment surface 1122 respectively formed along the height direction. The sealing member 2 is located in the communication port 111 and includes a support 21, a flow portion 22, an elastic portion 23, and an abutment portion 24. The flow portion 22 is connected to one end of the support 21 and has a flow port communicating with the outside. 221, one end of the elastic part 23 is connected to the flow part 22 and the other end is used to abut against the first abutting surface 1121. The abutting part 24 is connected to the other end of the support 21 and is used to abut against the second abutting surface 1122. In the first state, the elastic part 23 is in the return state and the abutting part 24 abuts against the second abutting surface 1122 to prevent the inner cavity of the container from communicating with the outside. In the second state, pressure is applied to the sealing member 2, so that the elastic part 23 is in the compressed state, the abutting part 24 is disengaged from the second abutting surface 1122, and the flow port 221 of the flow part 22 communicates with the inner cavity of the container to make the inner cavity of the container communicate with the outside.

[0033] 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 111, which communicates with the inner cavity of the container. Products can be placed into and removed from the container through the communication port 111. Connector 1 has an annular stepped portion 112 protruding within the communication port 111. The stepped portion 112 has two planes along its height direction: the upper plane is the first abutment surface 1121, and the lower plane is the second abutment surface 1122.

[0034] The sealing component 2 is located in the communication port 111. The sealing component 2 includes a support column 21, a flow section 22, an elastic section 23, and an abutment section 24. The support column 21 is cylindrical. The flow section 22 is connected to the upper periphery of the support column 21. The connection method can be welding, integral molding, etc., which are not limited in this application. The flow section 22 is provided with a flow port 221 for communicating with the outside. The flow port 221 extends through the flow section 22 along the height direction of the support column 21. There can be multiple flow ports 221, such as three, four, or five. This application does not limit the number of flow ports 221. Multiple flow ports 221 are arranged at intervals along the periphery of the support column 21. One end of the elastic section 23 is connected to the periphery of the flow section 22, and the other end of the elastic section 23 is used for abutment against the first abutment surface 1121.

[0035] The abutment part 24 is connected to the lower periphery of the support column 21. The connection method can be welding, integral molding, etc., which are not limited in this application. The cross-sectional area of ​​the abutment part 24 is circular. The maximum cross-sectional area of ​​the abutment part 24 is greater than the cross-sectional area of ​​the connecting opening 111. The abutment part 24 is used to abut against the second abutment surface 1122. When the abutment part 24 abuts against the second abutment surface 1122, the connecting opening 111 is blocked.

[0036] Reference Figure 1 -

[0037] Figure 3 In the first state, the elastic part 23 is in the return state, and the abutting part 24 abuts against the second abutting surface 1122, so that the connecting port 111 is in the blocked state and the container is in the sealed state, reducing the product's contact with air and improving the product's shelf life and freshness.

[0038] Reference Figure 1 , Figure 4 -

[0039] Figure 5 In the second state, external pressure is applied to the sealing member 2, causing the elastic part 23 to be in a compressed state, the abutting part 24 to disengage from the second abutting surface 1122, and the flow port 221 of the flow part 22 to communicate with the inner cavity of the container, so that the inner cavity of the container can communicate with the outside.

[0040] 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.

[0041] Reference Figure 1In some optional embodiments, the elastic portion 23 and the flow portion 22 are integrally formed, and the elastic portion 23 is provided with a deformable opening 231. The elastic portion 23 and the flow portion 22 are made of the same material, and the elastic portion 23 and the flow portion 22 are integrally formed. There are multiple elastic portions 23, such as three or four, etc., which is not limited in this application. The multiple elastic portions 23 are arranged at intervals along the periphery of the flow portion 22. The deformation opening 231 is provided such that when the deformation opening 231 shrinks, the elastic portion 23 is in a compressed state, and when the deformation opening 231 expands, the elastic portion 23 is in a return state.

[0042] In some alternative embodiments, the elastic portion 23 is arranged in a "V" shape on the side facing the first abutment surface 1121. The "V" shape is more conducive to the compression of the elastic portion 23 than the "U" shape.

[0044] Figure 5 In some optional embodiments, the abutment portion 24 is provided with a bevel 241 on its periphery so that the abutment portion 24 can extend into the communication port 111, thereby facilitating the installation of the abutment portion 24 into the inner cavity of the connector 1, and facilitating the abutment portion 24 to be located below the second abutment surface 1122.

[0045] In some optional embodiments, a deformation groove 242 is provided on the side of the abutment portion 24 opposite to the flow portion, and the deformation groove 242 is arranged in a "+" shape. The deformation groove 242 allows the abutment portion 24 to deform when it is installed in the inner cavity of the connector 1, thereby improving the smoothness of the installation of the abutment portion 24 in the inner cavity of the connector 1. The deformation groove 242 is arranged in a "+" shape to improve the deformation effect of the abutment portion 24.

[0046] In some optional embodiments, a deformation hole 211 is provided at the end of the support column 21 facing the abutment portion 24, and the deformation hole 211 communicates with the deformation groove 242. The deformation hole 211 extends along the length direction of the support column 21, but the deformation hole 211 is a blind hole, so as not to affect the strength of the upper end of the support column 21. The deformation hole 211 communicates with the deformation groove 242, thereby further improving the deformation effect of the abutment portion 24 and further improving the smoothness of the abutment portion 24 extending into the inner cavity of the connector 1.

[0047] In some optional embodiments, the connector 1 includes a first connecting portion 11 and a second connecting portion 12. A stepped portion 112 is disposed on the first connecting portion 11, and the second connecting portion 12 is used to connect with a container. The first connecting portion 11 is provided with a slot 113, and the second connecting portion 12 connects to the first connecting portion 11 by extending into the slot 113. The separate arrangement of the first connecting portion 11 and the second connecting portion 12 simplifies their manufacturing process compared to a one-piece connector 1. The first connecting portion 11 is provided with a slot 113, the opening of which is downward, and the slot 113 is annularly arranged. The second connecting portion 12 is also annularly arranged. When the second connecting portion 12 is inserted into the slot 113, the first connecting portion 11 connects to the second connecting portion 12.

[0048] To facilitate the insertion of the second connecting part 12 into the slot 113, the opening end of the slot 113 may be provided with an inclined guide to increase the opening of the slot 113.

[0049] In some optional embodiments, the first connecting portion 11 has a slot 113 with a locking groove 1131, and the second connecting portion 12 has a locking portion 121 adapted to the locking groove 1131. The locking portion 121 extends into the locking groove 1131 to connect the first connecting portion 11 and the second connecting portion 12. The locking groove 1131 and the locking portion 121 are adapted to each other. When the locking portion 121 extends into the locking groove 1131, the first connecting portion 11 and the second connecting portion 12 engage, improving the stability of the connection between the first connecting portion 11 and the second connecting portion 12 and reducing the probability of the first connecting portion 11 and the second connecting portion 12 disengaging.

[0050] The engaging groove 1131 is an annular groove, and the engaging part 121 is annular. The outer diameter of the engaging part 121 gradually decreases in the direction away from the abutting part 24. That is, the engaging part 121 is provided with an inclined surface, and the engaging groove 1131 is also provided with an inclined surface, so that the engaging part 121 can easily extend into the engaging groove 1131.

Figure 7 Show Figure 6 The diagram shows a cross-sectional view of the discharge device along the CC direction. In some optional embodiments, a cover 3 is also included, which covers the connector 1 and is threadedly connected to the first connecting portion 11. The inner wall of the cover 3 is provided with internal threads, and the outer wall of the connector 1 is provided with external threads, thereby facilitating the connection between the cover 3 and the connector 1 and also facilitating the removal of the cover 3 from the connector 1.

The cover 3 applies pressure to the sealing element 2, causing the elastic part 23 to be in a compressed state. The interior of the cover 3 is in communication with the inner cavity of the container, preventing the discharge device from exploding under negative pressure.

[0054] In some optional embodiments, a sealing part 31 is provided on the side of the cover 3 facing the step portion 112. The sealing part 31 is used to extend into the communication port 111. The sealing part 31 is made of the same material as the cover 3, and the sealing part 31 is integrally formed with the cover 3. The sealing part 31 is annular and is used to extend into the cavity of the communication port 111. The provision of the sealing part 31 can increase the sealing effect of the cover 3.

[0055] Furthermore, the wall thickness of the sealing part 31 gradually decreases in the direction toward the step part 112, so that the sealing part 31 can extend into the communication port 111.

[0056] In some optional embodiments, the outer periphery of the cap 3 is provided with a plurality of anti-slip ridges 32, which are spaced apart along the outer periphery of the cap 3. The anti-slip ridges 32 facilitate the operator to unscrew the cap.
