Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work all belong to the protection scope of the present invention.

When an element is referred to herein as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The directional terms of front, rear, upper and lower, etc. are defined as the positions of the components in the drawings and the positions of the components relative to each other, and are used for clarity and convenience of the technical solution. It is to be understood that the use of the directional terms should not be taken to limit the scope of the claims.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

As shown in fig. 1, the anti-pocketing wine bottle cap according to one embodiment of the present invention mainly comprises a wine outlet nozzle assembly that can be fixed on the bottle mouth portion 30 and an upper cover assembly that covers the wine outlet nozzle assembly.

The wine outlet nozzle assembly comprises an inner plug 12, a sealing bead 13, an inner main body 14, a check valve assembly and an outer main body 11 (not shown in the figure), wherein the inner plug 12 comprises a main body part 121 with a cylindrical structure, a first elastic sealing ring 122 is arranged at the lower end of the main body part 121, and a second elastic sealing ring 123 is arranged on the inner wall of the middle part of the main body part 121. A sealing bead 13 is received in the inner plug 12, said sealing bead 13 being in sealing engagement with the radially inner end of said first resilient sealing ring 122 for sealing the central bore of the first resilient sealing ring 122.

The one-way valve assembly is disposed in the inner plug 12 above the sealing bead 13 and is slidable up and down. The check valve assembly comprises a check valve main body 15 and an elastic suction sleeve 16, wherein the check valve main body 15 is in sealing fit with the radial inner end of the second elastic sealing ring 123 and is used for sealing the central hole of the second elastic sealing ring 123. The elastic suction sleeve 16 is connected with the lower end of the check valve body 15, and the elastic suction sleeve 16 has a groove 161.

The inner main body 14 is a cylindrical structure, the inner main body 14 is sleeved on the inner plug 12, the inner main body 14 is provided with a mounting part at the lower part and a wine outlet part at the upper part, a plurality of anti-skidding convex teeth are arranged on the inner wall of the mounting part, and the mounting part is fixedly sleeved at the bottle mouth part 30. The outer peripheral surface of the wine outlet part is provided with an external thread. The outer body 11 is sleeved on the mounting part of the inner body 14, and a first rotation stopping structure for preventing the relative rotation of the outer body 11 and the inner body 14 is arranged between the two bodies.

The upper cover component comprises an outer cover 21 and an inner cover 22, the inner cover 22 is fixedly arranged in the outer cover 21, and the inner wall of the inner cover 22 is provided with an internal thread matched with the external thread on the wine outlet part. The top center of the outer cap 21 is provided with a center pillar 211 extending downward, and the lower end of the center pillar 211 is inserted into a fixing hole 151 at the upper end of the check valve body 15.

When the upper cover assembly is screwed on the inner main body 14 for connection, the lower end of the center pillar 211 abuts against the upper end of the check valve main body 15, the check valve main body 15 and the elastic suction sleeve 16 are driven to move downwards, and the inner wall of the groove 161 of the elastic suction sleeve 16 is tightly attached to the surface of the sealing bead 13. When the bottle cap is opened, the central column 211 of the inner cap 22 drives the check valve main body 15, the elastic suction sleeve 16 and the sealing bead 13 to move upwards to be separated from the inner plug 12, so that the problem that wine cannot be poured out due to negative pressure in the bottle is solved.

As an example, the bottom of the groove 161 is a hemisphere shape fitted with the sealing bead 13. Therefore, the contact area between the elastic suction sleeve 16 and the sealing bead 13 is large, and the bonding force between the elastic suction sleeve 16 and the sealing bead 13 is large, so that the sealing bead 13 is easier to take out. Preferably, the sealing bead 13 is in interference fit with the inner wall of the groove 161, so as to further increase the bonding force between the elastic suction sleeve 16 and the sealing bead 13.

As an example, the opening portion of the groove 161 is cylindrical, and the diameter of the opening portion of the groove 161 is smaller than the diameter of the sealing bead 13, so that the sealing bead 13 is not easily released from the groove 161.

As an example, the elastic suction sleeve 16 is made of a silica gel material to meet the requirements of food.

As an example, the lower end of the check valve body 15 is provided with a mounting hole, the upper end of the elastic suction sleeve 16 is provided with a mounting post 162, and the mounting post 162 is inserted into the mounting hole. The structure is convenient to install.

As an example, the outer diameter of the elastic suction sleeve 16 is smaller than or equal to the bore diameter of the central bore of the second elastic sealing ring 123. During assembly, the elastic suction sleeve 16 is conveniently arranged in the inner plug 12.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
