CN2245040Y - Explosion-proof bottle lid for beer bottle - Google Patents

Abstract

The utility model relates to an explosion-proof bottle lid for a beer bottle. The utility model has the advantage of particularly simple structure because only the original bottle lid is provided with a small hole, and the original rubber sealing ring is slightly thickened. Only the original bottle cap is slightly changed by a brewery, and the whole device is not changed and is not specially required. Because the pressure in the bottle is too high is stressed at the same time, a sealing pressure releasing gasket is broken under the action of the pressure in the bottle, pressure is released in time, and the threat of explosion of beer bottles to the lives and property of production and transportation persons and consumers is eliminated.

Description

Explosion-proof beer bottle cap

The utility model is a kind of explosion-proof beer bottle cap.

At present, the beer of China's production mostly is glass bottle.Because the beer bottle repeated usage, bottle is easy to fragmentation because of producing in the transportation to collide with and self wear out.If the beer sterilizing of loading onto in the reusable beer bottle is not thorough or fermentation is not thorough, beer can ferment in bottle, and pressure of the inside of a bottle raises thereupon.Because bottleneck is that pressure of the inside of a bottle can't be discharged with iron covering and packing seal leak free, beer bottle is under the effect of bottle inner high voltage, and the fragmentation of very easily exploding is hurted sb.'s feelings.

The purpose of this utility model is that a kind of device that improves original bottle cap will be provided, and it can prevent effectively because of the too high blast that causes of bottle internal pressure.

The purpose of this utility model is achieved in that as shown in drawings, on original beer bottle bottle cap 2, pre-subpunch one aperture 1 is increased to certain thickness to original sealing rubber pad, makes it to play the sealing pressure release pad 3 that sealing effectiveness can bear bottle interior normal pressure again.But when pressure of the inside of a bottle raise because of a variety of causes, under the effect of pressure of the inside of a bottle, sealing pressure release pad 3 was broken through at aperture 1 place that bottle cap 2 is opened, and advances pressure release, prevented that the beer bottle blast from hurting sb.'s feelings.

The utility model is thickeied original rubber gasket a little because need only open an aperture on original bottle cap, so structure is simple especially, brewery need only change on original bottle cap a little, and integral device is not had what change and specific (special) requirements.Simultaneously, owing to be conceived to when the pressure of the inside of a bottle superpressure, under the pressure of the inside of a bottle effect, sealing pressure release pad is broken through, and the danger side of body of beer bottle blast to production and transport personnel and customer's lives and properties eliminated in pressure release in time.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Figure one is the section-drawing of beer bottle bottle explosion-proof bottle cap.

Figure two is birds-eye vieies of explosion-proof beer bottle cap.

Among the figure: 1 aperture, 2 bottle caps, 3 pressure release packing seals.Promptly opening an aperture 1 bottle cap 2 the insides on bottle cap 2 is sealing pressure release pads 3.

The lid beer that gone to seal can and when the pressure of the inside of a bottle superpressure seals pressure release pad 3 and is broken through by aperture 1 place by pressure of the inside of a bottle thus, thereby reaches the purpose of pressure-relief explosion-proof.

Claims (1)

1, explosion-proof beer bottle cap is a kind of bottle cap that prevents the blast of beer bottle superpressure, and this bottle cap principal character is: at bottle cap (2) upper punch one aperture (1), sealing pressure release pad (3) is in the inside of bottle cap (2).
