Abstract

The utility model belongs to a safety explosion-proof bottle cover which can avoid beverage bottles and beer bottles from exploding. Pressure is automatically reduced when the pressure in a bottle body reaches a certain value so that the bottle body can not explode to injure people. The utility model has the advantage of no influence of the bottle body appearance, simple manufacturing process, low cost, etc.

Description

A kind of safety anti-explosive bottle cap
The utility model relates to a kind of beverage of avoiding.The safety anti-explosive bottle cap of beer bottle blast.
At present, cause beverage.The major cause of beer bottle blast has: the one, and new bottle is off quality, and the uneven distribution voltage endurance capability is poor; The 2nd, the can again of the old bottle of a large amount of recovery, bottle lowers through repeated use internal pressure-resistant ability; The 3rd, beverage.Sterilization is not thorough behind the beer filling, and the back bacterium of dispatching from the factory is fermented and causes pressure of the inside of a bottle to increase, and above aspects reason can both cause the bottle explosion phenomenon to take place.The method that is now adopted generally is to be coated with in the bottle appearance to brush adhesives, and drying is solidified the back and formed protective film.Though this protective film can improve the internal pressure-resistant ability of bottle to a certain extent, the phenomenon of when interior pressure surpasses certain value, still can blasting; In addition,, both increased too high cost, influenced the attractive in appearance of whole appearance again at whole bottle appearance brushwork adhesive.
The purpose of this utility model provide a kind of can be at beverage.Automatic explosive decompression when the beer bottle internal pressure reaches certain value, thereby the safety anti-explosive bottle cap that bottle can not be blasted.
The purpose of this utility model is achieved in that at the sphere of 1 projection of punching press again of stamping forming bottle cap inner and upper, the tangent otch of sphere of projection is given at 2 centers of punching press mutually on this protruding sphere, to not cut off, make the otch connecting bridge extremely thin, the otch connecting bridge is ruptured along otch, explosive decompression, bottle just can not explode.
In order to insure the sphere that can be depressed into few 1 projection more a bottle cap upper punch, be depressed into few 2 centers in the sphere upper punch and give the tangent otch of protruding sphere mutually, like this, safety factor is increase further, improves.
Owing to adopt such scheme, the otch connecting bridge is ruptured along otch, explosive decompression, it is simple, with low cost that bottle is processed as stamped technology with regard to the bottle cap that can not explode.
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is a safety anti-explosive bottle cap birds-eye view.
Fig. 2 is Fig. 1 I--I cutaway view.
According to Fig. 1.Shown in Figure 2, be depressed into the sphere 2 of few 1 projection in bottle cap 1 upper punch, be depressed into few 2 centers in sphere 2 upper punches and give the tangent otch of protruding sphere 3 mutually, to not cut off, make otch connecting bridge A extremely thin, otch connecting bridge A is ruptured along otch, explosive decompression, bottle just can not explode.
According to the above, the bottle cap upper punch in Fig. 1 is depressed into the sphere 2 of few 1 projection, is depressed into few 2 centers in sphere 2 upper punches and gives the tangent otch of protruding sphere mutually, works as beverage like this.When the beer bottle internal pressure reaches certain value, bottle will be blasted, and at this moment the connecting bridge A that keeps of 3 places of the otch on sphere 2 has born incessantly that pressure of the inside of a bottle can rupture along otch, pressure of the inside of a bottle is descended rapidly, thereby blast can not taken place.
The safety explosion-proof bottle cap has does not affect bottle overall appearance, worker The characteristics such as skill is simple, and is with low cost are bottled drinks. Desirable explosion-proof of beer Bottle cap.
