Description

Technical Field

[0001] The utility model relates to a bottle cap. Background Art

[0002] Bottle caps, as sealing members for bottles, are widely used in the beverage industry. For example, the utility model patent with announcement number CN207497280U discloses an anti-counterfeiting wine bottle cap, comprising a cap body and a clamp for connecting the cap body to the bottle mouth. The cap body is a hollow structure, comprising an upper cap and a lower cap that interlock with each other. The bottom surface of the upper cap is provided with an anti-slip ring, and correspondingly, the top surface of the lower cap is provided with a ridge that cooperates with the anti-slip ring. During assembly, the anti-slip ring of the upper cap extends into the ridge of the lower cap, and the bottom surface of the lower cap is provided with an inner plug that cooperates with the inner cavity of the bottle mouth. The inner plug is made of a polymer elastomer material and is integrated with the lower cap plastic part through injection molding using a special machine. However, the upper and lower caps are supported only by the anti-slip ring and the ridge, which is not strong enough. When the inner plug is injected, the lower cap is easily deformed.

[0022] like Figure 1-Figure 4 The figure shows a bottle cap according to the first embodiment of the present invention, comprising a cap body and a bottle stopper 1. The cap body comprises an upper cover 2 and a lower cover 3, the upper cover 2 and the lower cover 3 being detachably connected. The bottle stopper 1 and the bottom surface of the lower cover 3 are hot-melt connected. A support block 4 is provided between the upper cover 2 and the lower cover 3. The bottom surface of the support block 4 abuts the lower cover 3, and the upper end of the support block 4 abuts the upper cover 2. The lower cover 3 and / or the upper cover 2 are provided with a first boss 5 for positioning the support block 4. The provision of the support block 4 increases the support area and strength, thereby improving the support for the lower cover 3.

[0023] The upper cover 2 is provided with a first sleeve 21, and the support block 4 is provided with a second sleeve 41. The first sleeve 21 and the second sleeve 41 are plugged into each other. The plugging can be done by inserting the first sleeve 21 into the second sleeve 41, or the second sleeve 41 into the first sleeve 21. This structure further improves the support for the lower cover 3 and makes the connection between the support block 4 and the cover body more secure.

[0024] The bottom surface of the lower cover 3 is provided with a second boss 31. When the bottle stopper 1 is formed by injection, the bottle stopper 1 will wrap around the second boss 31, so that the connection between the bottle stopper 1 and the lower cover 3 is more secure.

[0025] The bottom surface of the lower cover 3 is provided with a plurality of openings or slots 32. In this embodiment, the slots 32 are four grooves arranged around the center circumference of the lower cover 3. During injection molding of the bottle stopper 1, a protrusion shaped like the slots 32 forms on the upper end of the hot-melt bottle stopper 1. The upper end of the protrusion then bonds to the bottom surface of the support block 4, thereby bonding the support block 4, the lower cover 3, and the bottle stopper 1 together, further strengthening the connection between the support block 4, the bottle stopper 1, and the lower cover 3.

[0026] The bottle cap lock assembly is also included. The bottle cap lock assembly includes a left half hoop 61 and a right half hoop 62, one end of the left half hoop 61 and the right half hoop 62 being hinged, and the other end of the left half hoop 61 and the right half hoop 62 is provided with a locking portion 63, and the locking portion 63 is provided with a locking hole 64. A locking plate 65 is hinged on the right half hoop 62 or the left half hoop 61, and the locking plate 65 is provided with a fourth through hole 66. The upper ends of the inner walls of the left half hoop 61 and the right half hoop 62 are buckled on the bottle cap, and the lower ends are buckled on the bottle mouth. The locking plate 65 is buckled on the locking portions 63 of the left half hoop 61 and the right half hoop 62 through the fourth through hole 66. In this way, the bottle cap cannot be removed without opening the bottle cap lock assembly. Further, a disposable latch can be provided in the locking hole 64 to achieve anti-counterfeiting, or a lock can be connected to the locking hole 64 to prevent it from being opened by others.

[0027] The right half hoop 62 or the left half hoop 61 is provided with a hook 67 , and the lock plate 65 is provided with a rotating shaft 68 . The lock plate 65 is hinged to the hook 67 via the rotating shaft 68 .

[0028] like Figure 5-Figure 7The second embodiment of the present invention is shown in FIG. This embodiment differs from the first embodiment in that the first sleeve 21 is open at the top and bottom, a third sleeve 71 is disposed within the first sleeve 21, the support block 4 is provided with a first through-hole 42, the lower cover 3 is provided with a second through-hole 33, and the bottle stopper 1 is provided with a third through-hole 11. A valve stem 72 is disposed within the third sleeve 71, which passes through the first through-hole 42, the second through-hole 33, and the third through-hole 11, in sequence. A sealing structure is provided between the valve stem 72 and the bottle stopper 1. The sealing structure includes a first step 721 disposed at the lower end of the valve stem 72 and a sealing gasket 73 disposed between the first step 721 and the bottle stopper 1. The third sleeve 71 is provided with a second step 711, the valve stem 72 is provided with a third step 722, and a spring 73 is disposed between the second step 711 and the third step 722. Generally, the spring 73 supports the valve stem 72, causing the first step 721 to press against the sealing gasket 73, achieving a seal.

[0029] By providing the above structure on the bottle cap, the gas inside the bottle can be circulated to the outside without opening the bottle cap. When ventilation is needed, the valve stem 72 is pressed downward so that the first step 721 no longer presses the sealing gasket 73, and the gas can circulate. For example, when a large air pressure is generated inside the bottle, the gas inside the bottle can be discharged by pressing the valve stem 72 to avoid the harm caused by excessive pressure inside the bottle. Or when the bottle cap is used for a wine jar with a faucet, when the wine is released from the faucet of the wine jar, the gas above the wine jar cannot be connected to the outside world, resulting in the inability to release the wine. At this time, by pressing the valve stem 72, the gas inside and outside can circulate, and the faucet can be used to release the wine.

[0030] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Without departing from the spirit and scope of the present invention, simple modifications and substitutions by those skilled in the art are within the scope of protection of the present invention.
