Abstract
The utility model relates to an explosion-proof bottle cover, which comprises a crown-shaped cover body provided with pressure release holes. A W-shaped framework is arranged in the crown-shaped cover body; air holes are arranged in the inner wall of the W-shaped framework; an elastic rubber sleeve of a release valve is sleeved on the W-shaped framework. The explosion-proof bottle cover of the utility model can effectively prevent a beverage bottle or a beer bottle with the explosion-proof bottle cover from bursting.
Description
Technical field
The utility model relates to a kind of bottle cap, particularly relates to a kind of explosion-proof bottle cap.
Background technology
At present, bottled drink, particularly the bottle cap of beer adopts iron sheet to be stamped to form mostly, be sealed in bottle mouth position then, since contain gas in beverage or the beer, normal because of factors such as rocking of temperature build-up or handling process cause pressure of the inside of a bottle to increase suddenly, thereby lead to the bottle bursting accident, not only cause serious personal injury, and can bring immeasurable economy and credibility loss to producer.
Summary of the invention
The purpose of this utility model is the defective that overcomes above-mentioned prior art, and a kind of explosion-proof bottle cap that can effectively prevent beverage bottle or beer bottle explosion is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of explosion-proof bottle cap comprises that one has the crown lid of relief hole, is provided with " W " shape skeleton in the described crown lid, has pore on the inwall of " W " shape skeleton, is with the aie escape valve elastic rubber sleeve on it;
Described " W " shape skeleton outside also is provided with seal gasket.
Explosion-proof bottle cap of the present utility model utilizes the one-way only operation performance of aie escape valve elastic rubber sleeve, realizes explosion prevention function, and concrete principle is: when pressure of the inside of a bottle surpasses 2kg/cm
2The time, the aie escape valve elastic rubber sleeve is pushed open by force, loses heart; When pressure of the inside of a bottle is lower than 2kg/cm
2The time, the aie escape valve elastic rubber sleeve is because the elastic force effect, and SELF CL can not enter in the bottle bottle outer air again, like this, has both guaranteed that a bottle interior material never degenerated, and can prevent that again bottle from blowing.
