DETAILED DESCRIPTION

[0028] The present application will be described in detail below with reference to the accompanying drawings. Figures 1-9 The embodiments of the present application will be described in detail.

[0029] A beverage cover, comprising a bottle mouth sleeve 1, a piercing member 2 located in the bottle mouth sleeve 1, and an upper cover 3 threadedly connected with the bottle mouth sleeve 1. The bottom of the bottle mouth sleeve 1 is provided with a sealing film 4. The bottle mouth sleeve 1 and the piercing member 2 comprise mutually cooperating guide components. When the upper cover 3 rotates relative to the bottle mouth sleeve 1, the upper cover 3 moves in a direction away from the sealing film 4 and drives the piercing member 2. The piercing member 2 first descends in the bottle mouth sleeve 1 and then rotates in the bottle mouth sleeve 1 under the action of the guide components, thereby piercing and cutting the sealing film 4.

[0030] The guide components comprise a plurality of first guide strips 11 arranged on the inner side of the bottle mouth sleeve 1 and a plurality of second guide strips 21 arranged on the outer side of the piercing member 2. The distance between two of the second guide strips 21 is slightly greater than the width of the first guide strips 11. One of the first guide strips 11 is inserted between the two second guide strips 21, and the remaining first guide strips 11 are respectively and correspondingly attached to the remaining second guide strips 21. The first guide strips 11 and the second guide strips 21 cooperate with each other to make the piercing member 2 vertically descend in the bottle mouth sleeve 1, thereby piercing the sealing film 4 below.

[0031] The outer side of the piercing member 2 is provided with a plurality of flanges 22, the inner side of the bottle mouth sleeve 1 is provided with a stepped hole 14 structure, the diameter of the lower part of the stepped hole 14 is smaller than that of the upper part, and the outer diameter of the flange 22 is the same as the diameter of the lower part of the stepped hole 14. The flange 22 is fitted with the stepped hole 14, so that the piercing member 2 is clamped in the bottle mouth sleeve 1 and can move only by driving the driving piece 31.

[0032] The inner top surface of the upper cover 3 is provided with a plurality of driving pieces 31 at intervals, each driving piece 31 has a guide surface 32 and a pushing surface 33, and the inner side of the piercing member 2 is provided with a plurality of stop teeth 24 for each driving piece 31 to press and lift, and the guide surface 32 is an arc surface. The guide surface 32 presses the stop tooth 24 to make the piercing member 2 descend, and the pushing surface 33 presses the stop tooth 24 to make the piercing member 2 rotate.

[0033] The upper part of the stop tooth 24 is chamfered on both sides, the chamfer can better fit with the guide surface 32, and the inner side of the stop tooth 24 is connected with a limiting block 25 at one end, which can prevent the driving piece 31 from being pulled out of the stop tooth 24.

[0034] The lower part of the piercing member 2 is provided with a plurality of curved piercing teeth 23.

[0035] The number of piercing teeth 23 is three, which are first piercing teeth 231, second piercing teeth 232 and third piercing teeth 233, the included angle between the first piercing teeth 231 and the second piercing teeth 232 and the included angle between the second piercing teeth 232 and the third piercing teeth 233 are the same, the included angle between the first piercing teeth 231 and the second piercing teeth 232 is smaller than the angle of rotation of the piercing member 2 relative to the bottle mouth sleeve 1, and when rotating, the piercing teeth 23 can reach and exceed the position of the previous piercing teeth 23, so that the piercing teeth 23 can cut a complete arc on the sealing film 4, and the included angle between the first piercing teeth 231 and the third piercing teeth 233 on the side not containing the second piercing teeth 232 is greater than the angle of rotation of the piercing member 2 relative to the bottle mouth sleeve 1, so that the piercing teeth 23 cannot cut a complete circle on the sealing film, thereby leaving a part of the sealing film 4 still connected with the bottle mouth sleeve 1.

[0036] The inner side of the bottle mouth sleeve 1 is provided with a plurality of limiting strips 13 at the lower part, which are used to prevent the piercing member 2 from sliding out of the bottle mouth sleeve 1.

[0037] The bottle mouth sleeve 1 and the upper cover 3 are provided with an anti-theft component, the anti-theft component includes an anti-theft block 5 fixed on the bottle mouth sleeve 1, and a plurality of tension reinforcing ribs 6 are connected between the anti-theft block 5 and the upper cover 3. The bottle mouth sleeve 1 is provided with a fixing hole 12, the lower part of the anti-theft block 5 is provided with a fixing foot 51, and the fixing foot 51 of the anti-theft block 5 is inserted into the fixing hole 12 of the bottle mouth sleeve 1. When the upper cover 3 rotates relative to the bottle mouth sleeve 1, the connection between the tension reinforcing rib 6 and the anti-theft block 5 will be disconnected, which can be used to judge whether the upper cover 3 has been opened.

[0038] The working principle of the present application is that the connection between the tensile reinforcing rib 6 and the anti-theft block 5 is disconnected by rotating the upper cover 3. The driving pieces 31 in the upper cover 3 will be clamped on the notches 24 to drive the notches 24 to run downward along the guiding surfaces 32 of the driving pieces 31. Due to the cooperation of the first guiding strip 11 and the second guiding strip 21, the piercing member 3 moves vertically downward in the bottle mouth sleeve 1, and the piercing teeth 23 at the lower part of the piercing member 3 pierce the sealing film 4. When the notches 24 reach the pushing surfaces 33 from the guiding surfaces 32, the first guiding strip 11 and the second guiding strip 21 are separated from each other. At this time, the pushing surfaces 33 of the driving pieces 31 press the notches 24 to make the piercing member 2 rotate in the bottle mouth sleeve 1, so as to drive the piercing teeth 23 to rotate to cut the sealing film 4. The upper cover 3 continues to rotate, and the driving pieces 31 are separated from the notches 24 and rotated out of the bottle mouth sleeve 1.

[0039] The above is only the preferred embodiment of the present application, and the protection scope of the present application is not limited to the above-mentioned embodiment. Any technical solution falling within the concept of the present application shall fall within the protection scope of the present application. It should be noted that, for ordinary skilled in the art, some improvements and decorations without departing from the principle of the present application shall also be considered as falling within the protection scope of the present application.
