Bottle cap structure of glass bottle can
Technical Field
The utility model relates to a bottle cap structure of a glass bottle.
Background
Glass bottles are widely used as packaging containers for food, beverage and many products, and glass is a historical packaging material.

Furthermore, each connecting part is arranged around the center of the placement groove at equal intervals, and the inner side wall of each connecting part is flush with the inner side wall of the placement groove.
Furthermore, a separation net connected with the top and the outer side wall of the thickened part is arranged around the outer side wall of the positioning part, and each connecting part is arranged in the separation net.
Furthermore, the top of the sealing part is concavely formed with a semicircular blind hole, and the top end of the sealing part is positioned below the upper end face of the bottle cap body.
Furthermore, a sealing counter bore is formed in the bottom of the thickened portion, and a sealing ring is arranged in the sealing counter bore; the sealing counter bore and the air inlet hole are coaxially arranged; the top of the sealing block is matched with the sealing counter bore.
Furthermore, the air inlet hole is a conical through hole, and the sealing part is a conical sealing body matched with the conical through hole.
Further, the air inlet hole is a circular through hole, and the sealing part is a cylindrical sealing body matched with the circular through hole.
In order to better realize ventilation, the bottle cap body is also provided with a group of ventilation holes penetrating through the thickened part, and the ventilation holes are communicated with the sealing counter bore.
In order to facilitate assembly and positioning of the return pressure spring, the bottom of the sealing block and the bottom of the placement groove are respectively provided with a positioning blind hole matched with the return pressure spring.
Furthermore, the thickened part and the positioning part are coaxially arranged cylindrical structures, and the diameters of the thickened part and the positioning part are the same; annular gaps are formed around the bottom of the outer side wall of the thickened part and the top of the outer side wall of the positioning part, and the upper end and the lower end of the separation net are arranged in the annular gaps.
The utility model has the beneficial effects that: the air inlet and the sealing of the bottle cap structure can be realized by the mutual matching of the thickened part, the positioning part, the air inlet hole, the sealing block, the sealing part and the return pressure spring; when the sealing part is pressed down, the sealing part and the air inlet hole are separated from a close fit state, so that the circulation of the air inside and outside the glass bottle can be realized through the air inlet hole, the air pressure inside and outside the glass bottle can is consistent, and the problem that the bottle cap of the glass bottle can not be opened due to the fact that the inside and outside atmospheric pressure is unbalanced because no redundant air exists in the glass bottle can in daily life is finally solved.
The utility model will be explained in more detail below with reference to the drawings and examples.

Detailed Description
Embodiment 1, as shown in fig. 1, 2, and 3, a bottle cap structure of a glass bottle can includes a bottle cap body, and further includes a thickened portion disposed on a lower end surface of the bottle cap body, the bottle cap body being provided with an air inlet hole penetrating through the thickened portion; a positioning part is arranged below the thickened part, a group of connecting parts are arranged between the thickened part and the positioning part, and the connecting parts are arranged at intervals; the upper end surface of the lower positioning part is provided with a placement groove, a sealing block which can extend up and down movement is arranged in the placement groove, the top of the sealing block is provided with a sealing part which is tightly matched with the air inlet hole, and a return pressure spring is arranged between the bottom of the placement groove and the bottom surface of the sealing block.
The sealing part is a rubber body or a rubber layer covers the sealing part, and a guide chamfer is arranged at the top of the sealing part. The guide chamfer is arranged so that the sealing part can be pushed into the air inlet hole again by the return pressure spring when returning.
The interval arrangement among all the connecting parts is embodied as a window structure formed among all the connecting parts.
