Abstract

The utility model relates to a bottle cap which can prevent a beer bottle body from exploding. A notch circular hole is arranged on an iron sheet cap of a beer bottle, a piece of circular sealing and air leaking plastic film are compacted on a bottle mouth and sealed, and the notch circular hole of the iron sheet cap is clung with an air leaking plastic film. When air pressure intensity in the beer bottle exceeds pressure proof intensity of the circular sealing and air leaking plastic film, the circular sealing and air leaking plastic film can be burst by gas, and the notch circular hole is lifted to process air leaking and explosion preventing.

Description

The explosion-proof beer bottle cap

The utility model relates to a kind of beer bottle device of explosion voluntarily that prevents, especially avoids bottled beer to cross strong explosion bottle because of the bottle internal gas pressure in storage, transportation, sales process and causes unexpected injury to human body.

At present, known bottled beer is made up of glass bottle and sealing iron covering, does not adopt any explosion protection, also makes known to the world without any the relevant technical materials of beer bottle explosion that prevents so far, so the beer bottle explosion incident of hurting sb.'s feelings is reported in media frequently.

The purpose of this utility model is to provide a kind of explosion-proof beer bottle cap, and it can not only prevent the explosion voluntarily of beer bottle, and does not influence the sealing property of beer bottle.

The purpose of this utility model is achieved in that at thickness 0.5mm, diameter 26mm round iron skin covers out the breach circular hole of a diameter 12mm, the breach that circular hole is reserved 2mm is connected with lid, with this iron sheet lid the circle of 1 diameter 26mm is sealed the plastic film of losing heart and is pressed on the beer bottleneck.Seal the plastic film cylindrical that loses heart for sealing film, thickness 1.5mm, interior circle is the film that loses heart, thickness 0.4mm, diameter 12mm, the air pressure that the THICKNESS CONTROL of the film that loses heart in the bottle is strong, and the air pressure in bottle surpasses the withstand voltage strong of the film that loses heart by force, gas will break through and lose heart film and raise the bottle cap breach circular hole anti-waterfall that loses heart, and this is identical with the disappointing principle of pressure cooker air valve.

Owing to adopted such scheme, can prevent the explosion voluntarily of beer bottle well, and simple in structure, production and processing also is easier to.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the iron covering breach circular hole planar view of first embodiment of the utility model.

Fig. 2 is the planar view of disappointing plastic film.

Fig. 3 is the dynamic lateral plan that Fig. 1 washes iron covering breach circular hole when losing heart open.

Fig. 4 is the iron covering standard-sized sheet circular hole planar view of second embodiment of the utility model.

Fig. 5 is the dynamic lateral plan that Fig. 4 washes out iron covering standard-sized sheet circular hole when losing heart.

Fig. 6 is the longitudinal diagram of Fig. 4, and the incision size ratio is 10: 1.

Among the figure 1, seal iron sheet bottle cap 2, iron covering breach circular hole 3, circular hole breach and iron covering body junction 4, sealing film 5, film 6, iron covering standard-sized sheet circular hole lose heart

Among first embodiment, seal iron sheet bottle cap (1) sealing film (4) is pressed on the beer bottleneck, beer bottle is sealed.When the bottle internal gas pressure surpasses by force the withstand voltage strong of the film that loses heart, gas will break through disappointing film (5) and raise iron covering breach circular hole (2) and lose heart explosion-proof.

Among second embodiment, sealing iron sheet bottle cap (1) is pressed on sealing film (4) on the beer bottleneck, with beer bottle sealing, when the bottle internal gas pressure surpasses the withstand voltage strong of the film that loses heart by force, gas will break through disappointing film (5) and wash out iron covering standard-sized sheet circular hole (6) and lose heart explosion-proof.

Iron covering standard-sized sheet circular hole kerf width is 0.1mm, and notch depth is 0.4mm, the recessed opening of similar pop can, and the disappointing thickness that seals the plastic cement that loses heart changes 0.2mm into and gets final product.

Claims

1. explosion-proof beer bottle cap, the iron sheet lid seals the plastic film of losing heart to circle and is pressed on beer bottle mouth back seal, and it is characterized in that: iron covering breach circular hole is glued with disappointing plastic film.

2. explosion-proof beer bottle cap according to claim 1 is characterized in that: iron covering standard-sized sheet circular hole is glued with disappointing plastic film.
