Abstract

The utility model relates to an explosion-proof bottle cap. A cap cover of the bottle cap existing in the prior art is provided with a safety hole, the compression strength of a sealing gasket is properly improved, and the compression strength of the sealing gasket is properly smaller than the compression strength of a bottle body. Therefore, when the gas pressure in the bottle is too high, the sealing gasket is firstly broken by the pressure so that the purposes of preventing the bottle body fro exploding is achieved by using the utility model. The utility model can be widely be used for the bottle cap of bottles containing material which easily generate gas pressure. The utility model is particularly suitable for producing beer bottle caps.

Description

Explosion-proof bottle cap
The utility model relates to a kind of wrapping glass cap.
When existing glass bottle packaging easily produces the air pressure material, tend to cause the glass bottle blast, as when making beer packing, after temperature build-up or violent vibrations, rocking, beer can produce gas and expand, when air pressure increases to ability to bear greater than bottle, will explode and hurt sb.'s feelings, this type of accident is of common occurrence.
The purpose of this utility model is will provide a kind of explosion-proof bottle cap that prevents the glass bottle blast at the problems referred to above.
Scheme of the present utility model is: offer safety vent on the metal nut cap of existing bottle cap, be contained in packing seal in the block and select for use compressive strength suitably less than the material of bottle compressive strength.
The utility model after the improvement can reach explosion-proof purpose, when the material of adorning in the glass bottle produces hypertonia, then can at first break through packing seal, and air pressure is discharged from the safety vent of metal nut cap, thereby decompression reaches explosion-proof purpose.
The utility model will be further described below in conjunction with accompanying drawing:
Accompanying drawing is a structural representation of the present utility model.
Embodiment: referring to accompanying drawing, make the bottle cap of a beer bottle, it has a metal nut cap 1 and a packing seal 2, has a safety vent 3 at the center of metal nut cap 1.The material thickness of packing seal is selected according to the size of safety vent 3 and the compressive strength of glass bottle, should guarantee that promptly (being no more than the compressive strength of glass bottle) when the bottle internal gas pressure is excessive then can break through from safety vent 3.

Claims (1)

1. explosion-proof bottle cap that uses for packing has metal nut cap and places packing seal in the block, it is characterized in that: have safety vent on metal nut cap, packing seal selects for use compressive strength suitably less than the material of bottle compressive strength.
