Specific implementation mode

[0023] The present invention will be specifically described below in conjunction with the accompanying drawings. As Figures 1-8 shown, the present invention mainly includes four parts, namely an inner cap 1 buckled on the bottle mouth 5, a gasket 2 arranged in the inner cap 1 and used to enhance the sealing effect, an outer cap 3 sleeved on the outer wall of the inner cap 1, and a locking part 4 arranged on the inner wall of the outer cap 3; they will be elaborated in detail below.

[0024] The inner cap 1 includes a cap part 101 that is circular and recessed downward to form a groove, a skirt 102 connected to the outer circular edge of the cap part 101, a first groove 103, a first protrusion 104, and a second groove 105 that are sequentially arranged on the skirt 102 from top to bottom and are located on a straight line. The first groove 103 and the first protrusion 104 are reinforcing ribs, which increase the strength. The cap part 101 and the skirt 102 are integrally formed. There are multiple skirts 102, and there is a gap between every two adjacent skirts 102, and the width of the gap is greater than the width of the locking part; since the skirt 102 needs to fit against the outer wall of the bottle mouth 5 after the bottle cap is locked, the skirt 102 is designed in an S shape, and its bending arc is determined by the outer wall arc of the bottle mouth 5 and is adapted to the outer wall of the bottle mouth 5; for the convenience of description and understanding, the S-shaped skirt 102 is divided into two sections from top to bottom, namely an upper bending section 1021 and a lower bending section 1022. One end of the upper bending section 1021 is connected to the cap part 101, and the other end is connected to the lower bending section 1022. There is a gap between the lower bending section 1022 and the recessed part in the bottle mouth 5 to reserve a deformation space. The first groove 103 is located in the upper bending section 1021 of the skirt 102, so that the first groove 103 can play a guiding role. The first protrusion 104 and the second groove 105 are located in the lower bending section 1022, and the second groove 105 is semicircular. At the same time, the end of the lower bending section 1022 far from the cap part 101 is linear. Using a linear shape will not be easily opened like an arc shape during rotation, which can play an anti-theft role.

[0025] The gasket 2 has a circular part like an ordinary gasket. Since the circular part of it is connected to the cover part 101, the circular part of the gasket 2 will also be sunken downward to form a groove. The outer circular edge of the circular part of the gasket 2 in the present invention bends downward. At this time, the outer wall of the downward-bending part is arc-shaped. The first groove 103 in the inner cover 1 will closely adhere to the arc-shaped outer wall of the downward-bending part in the gasket 2. The downward-bending part and the circular part are integrally formed to form a chamber. When the inner cover 1 is buckled onto the bottle mouth 5, the mouth for pouring out beer is located in the chamber. Therefore, the gasket 2 is located at the end of the bottle mouth 5. A plurality of second protrusions 201 in a circular ring shape are provided on the inner wall of the downward-bending part of the gasket 2, which can increase the sealing performance between the gasket 2 and the bottle mouth 5;

[0026] The locking member 4 is in a π shape, but in the bottle cap of the present invention, it rotates the π shape 90 degrees to the left. At this time, the vertical part of the locking member 4 is connected to the inner wall of the outer cover 3, and the arc surface is between the upper and lower horizontal parts. For the convenience of distinction and understanding, the two horizontal parts in the locking member 4 are respectively called the upper horizontal part 402 and the lower horizontal part 403 from top to bottom. A fixing member 401 is provided on the locking member 4. The distance between the lower horizontal part 403 and the fixing member 401 is greater than the thickness of the skirt 102, and the fixing member 401 is located below the lower horizontal part 403; the number of the locking members 4 is equal to the number of the skirts 102 and they correspond one by one. When the outer cover 3 is pressed onto the inner cover 1, the upper horizontal part 402 closely adheres to the connection part between the upper bending section 1021 and the lower bending section 1022 of the skirt 102. One end of the skirt 102 far from the cover part 101 is located between the lower horizontal part 403 and the fixing member 401, and the lower horizontal part 403 is located on the lower bending section 1022 of the skirt 102.

[0027] The above is the description of the structure of the bottle cap. Next, the working principles of the installation and opening of the bottle cap will be further described.

[0028] The working principle during the installation of the bottle cap: Buckle the inner cover 1 onto the bottle mouth 5 of the beer bottle filled with beer. The gasket 2 is located at the end of the bottle mouth 5 to seal the mouth for pouring out beer of the bottle mouth 5. At this time, the skirt 102 is located around the outer wall of the bottle mouth 5 and has not yet contacted the bottle mouth 5. When the machine covers the outer cover 3, it identifies and locates the position accurately, and presses the locking member 4 downward along the skirt 102 according to the position of the first groove 103. When it is pressed to the bottom of the skirt 1, due to the thrust of the outer cover 3, the skirt 102 is tightened and contacts the outer wall of the bottle mouth 5. One end of the skirt 102 far from the cover part 101 is located between the lower horizontal part 403 and the fixing member 401 and closely abuts against the locking member 4. The locking member 4 and the outer cover 3 lock the skirt 102 tightly. There is an interference fit between the locking member 4 and the skirt 102. At the same time, the sunken part in the cover part 101 will bulge. At this time, the bottle cap will lock the bottle mouth 5 and generate a seal.

[0029] Working principle when opening the bottle cap: Rotate the outer cap 3 by a certain angle so that the locking part 4 is located between adjacent skirt edges 102, that is, in the gap between adjacent skirt edges 102. Since one end of the skirt edge 102 far from the cap part 101 is linear, scratches will be left on the locking part 4 during the rotation process, so that it can be known whether the bottle cap has been opened, playing an anti-theft role. When the outer cap 3 rotates in place, the skirt edge 102 will not be subjected to thrust. Press the top of the cap part 101 with a finger, and the skirt edge 102 of the inner cap 1 will warp, lift the outer cap 3 upward, and the inner cap 1 will be taken out of the bottle mouth 5 together under the action of the outer cap 3, so that the bottle cap can be separated from the beer bottle mouth 5. The bottle cap of the present invention does not require any tools and can be directly opened by hand. After the bottle cap is taken out, it can be decided whether to use it for a second time according to needs. For example, if the beer at home is not finished and it is a waste to pour it out, the bottle cap can be used for a second time.

[0030] Embodiment 1.

[0031] The outer cap 3 of the present invention is circular ring-shaped, and the height of the outer cap 3 is less than the height of the locking part 4, which can save materials and costs. A plurality of oval first convex platforms 301 are arranged on the outer wall of the outer cap 3, so that the friction can be increased when rotating the outer cap 3 and it is not easy to slip; before the outer cap 3 is pressed in, the machine will identify the groove formed between every two adjacent locking parts 4 and the outer cap 3, and then make the groove correspond to the gap between every two adjacent skirt edges 102, so as to identify the position of the skirt edge 102. Through the rotation angle set by the machine, the locking part 4 is aligned with the skirt edge 102 and pressed down along the skirt edge 102 until it reaches the bottom.

[0032] Embodiment 2.

[0033] The height of the outer cap 3 of the present invention is greater than the height of the inner cap 1. A through circular groove is opened at the top of the outer cap 3, and the outer circular edge of the groove is uneven. Before the outer cap 3 is pressed in, the machine will identify the concave part in the outer circular edge of the circular groove and make the concave part correspond to the gap between every two adjacent skirt edges 102, so as to identify the position of the skirt edge 102. Through the rotation angle set by the machine, the locking part 4 is aligned with the skirt edge 102 and pressed down along the skirt edge 102 until it reaches the bottom; a lot of strip-shaped second convex platforms (not shown in the figure) are arranged on the outer wall of the outer cap 3, so that the friction can be increased when rotating the outer cap 3 and it is not easy to slip. The outer cap 3 wraps the bottle mouth 5 and the inner cap 1, which can play a protective role for them.

[0034] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the present invention. Some changes that may be made by those skilled in the art to some parts thereof all reflect the principle of the present invention and are within the protection scope of the present invention.
