Please refer to fig. 1 to fig. 9. One embodiment of the present invention provides a functional cover, which comprises a main cover body 1 and a gas release device 2, wherein the gas release device 2 is arranged at the top end of the main cover body 1.

The top end of the main cover body 1 is provided with a vent hole 11, and the vent hole 11 is provided with a sealing unit 12. The closing unit 12 may be a sealing film or a sealing cover. The side of the main cover body 1 is provided with lines convenient for users to twist.

The air release device 2 comprises a top cover body 21 and an inserting unit 22, wherein the inserting unit 22 is arranged at the bottom end of the top cover body 21, the inserting unit 22 faces the closing unit 12, and the air vent 11 can be switched from a closed state to an open state by the inserting unit 22. In the present embodiment, the inserting unit 22 is disposed at the center of the top cover 21, and accordingly, the vent hole 11 is also disposed at the center of the main cover 1. In other embodiments, the position of the inserting unit 22 may be changed according to actual design, and the position of the vent hole 11 corresponds to the position of the inserting unit 22.

Preferably, the ventilation hole 11 is provided with a ventilation duct 13 extending toward the bottom end of the main cover 1, the closing unit 12 is provided at the bottom end of the ventilation duct 13, and the inserting unit 22 is provided in the ventilation duct 13. In the initial state and the pressing state, the inserting unit 22 is arranged in the ventilation pipeline 13, so that the stability of the inserting unit 22 can be improved, and the pressing accuracy is ensured.

In this embodiment, the inserting unit 22 is composed of a plurality of inserting columns 221 arranged in a ring, and a ventilation gap is formed between adjacent inserting columns 221. In particular to

The number of the inserting columns 221 is 4, the size of the inserting columns 221 is gradually reduced from the top end to the bottom end thereof, and the ventilation gap between the two inserting columns 221 is gradually increased from the top end to the bottom end of the inserting columns 221, so that the sufficient ventilation gap is ensured to allow the gas in the beverage bottle to be exhausted out of the beverage bottle.

In other embodiments, the inserting unit 22 is composed of an inserting column 221, and the cross section of the inserting column 221 is a cross section. The insert column 221 forms a vent gap with the vent tube 13. The inserting unit 22 may also be a pin, and correspondingly, the sealing unit 12 may be a sealing film, and the pin is inserted through the sealing film for pressure relief.

Preferably, the bottom end of the inserting unit 22 is connected with the top end of the closing unit 12. After the inserting unit 22 ejects the closing unit 12 out of the vent hole 11, after air leakage occurs, the inserting unit 22 is retracted, and the closing unit 12 can move along with the inserting unit 22 so as to recover to a state of covering the vent hole 11, thereby realizing closing of the cover of the beverage bottle.

In one embodiment, one end of the closing unit 12 is fixedly connected to the vent pipe 13. Specifically, one end of the closing unit 12 is fixedly connected with the outer wall of the ventilation duct 13 through a connecting body, and after the inserting unit 22 pushes the closing unit 12 out of the ventilation hole 11, the closing unit 12 is prevented from falling off, so that the drinking safety is ensured.

Preferably, a plurality of support sheets 23 are annularly disposed at the bottom end of the top cover body 21, when the top cover body 21 approaches the main cover body 1, the support sheets 23 radially extend toward the main cover body 1, and a ventilation gap is formed between adjacent support sheets 23. Specifically, the supporting piece 23 has certain elasticity, and the supporting piece 23 is in a fan shape. When the user presses top lid body 21, support piece 23 is when radially extending toward the bottom of top lid body 21 is pressed close to, and the user stops pressing the back, support piece 23 resumes, the elasticity of support piece 23 makes top lid body 21 can keep away from main lid body 1.

The functional cover further comprises a hook 3, one end of the hook 3 is rotatably connected to the edge of the main cover body 1, and a concave portion 14 which is convenient for opening the hook 3 is arranged on the upper edge of the main cover body 1. The rotary connection can be formed by folding and rotating integrally, can also be connected through a rotating shaft or can be connected through a damping piece in a rotary mode.

The interior border cover of couple 3 is located the outer border of top lid body 21, the outer border of couple 3 with the outer border phase-match of main lid body 1. Specifically, the height of couple 3 with the high phase-match of top lid body 21, couple 3 can prevent that the user from bumping into by mistake top lid body 21 presses, also can prevent main lid body 1 from bumping into couple 3 is opened by mistake.

Preferably, when the hook 3 is covered on the top end of the main cover body 1, the distance between the outer edge of the support sheet 23 and the inner edge of the hook 3 is 0.5 mm to 1.5 mm. When the hook 3 is covered, the inner edge of the hook 3 limits the outward extension of the support sheet 23, so that the air leakage device 2 is limited and plays a role in safety.

In addition, many disposable beverages on the market, such as carbonated beverages, mineral water, fruit juice, herbal tea, milk tea and the like, solve the technical problem of good holding and holding on the bottle body. The cover is provided with no hanging ring which can be buckled, so that the portable function that people can hang the bottle cannot be realized. The functional cover is also provided with the hook, so that the function of carrying and hanging the functional cover by a user is realized.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
