Abstract

The utility model belongs to a safety explosion-proof bottle cap which can prevent 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 safety anti-explosive bottle cap of avoiding beverage, beer bottle blast.

At present, cause the major cause of beverage, beer bottle blast to have: the one, 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, behind beverage, the beer filling sterilization not thorough, the back bacterium of dispatching from the factory is fermented and causes pressure of the inside of a bottle to increase, 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, and 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 surface 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 on stamping forming bottle cap hole of punching press again, at plain cushion of the inner placement of bottle cap, the otch that intersect at 2 centers of punching press on plain cushion, to not cut off, make the otch connecting bridge extremely thin, this otch must correspond in the middle of the hole of institute's punching press on the bottle cap, and the otch connecting bridge is ruptured along otch, explosive decompression, bottle just can not explode.

Can be depressed into few 1 hole a bottle cap upper punch in order to insure more, the plain cushion upper punch in bottle cap is depressed into the otch that intersect at few 2 centers, and safety factor can further increase, improve like this.

Owing to adopt such scheme, plain cushion is placed in the bottle cap, otch on the plain cushion be again with bottle cap on the hole corresponding, the otch connecting bridge is ruptured along otch, the explosive decompression bottle just can not explode, the explosion-proof bottle cap manufacturing process is simple, and is with low cost.

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is a safety anti-explosive bottle cap expansion drawing.

Fig. 2 is a then cutaway view of safety anti-explosive bottle cap.

According to Fig. 1, shown in Figure 2, be depressed into few 1 hole 2 in bottle cap 1 upper punch, be depressed into the otch 4 that intersect at few 2 centers in bottle cap in-to-in pad 3 upper punches, to not cut off, make otch 4 connecting bridge A extremely thin, this otch 4 must correspond in the middle of the hole 2 of institute's punching press on the bottle cap 1, and otch 4 connecting bridge A are ruptured along otch, explosive decompression, bottle just can not explode.

According to the above, bottle cap 1 upper punch in Fig. 1, Fig. 2 is depressed into few 1 hole 2, be depressed into the otch 4 that intersect at few 2 centers in bottle cap in-to-in plain cushion 3 upper punches, otch 4 must correspond in the middle of the hole 2 of institute's punching press on the bottle cap 1, like this when beverage, when the beer bottle internal pressure reaches certain value, bottle will be blasted, at this moment the connecting bridge A that keeps of 4 places of the otch on plain cushion 3 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.

Characteristics such as the safety explosion-proof bottle cap has does not influence the bottle overall appearance, and manufacturing process is simple, and is with low cost are the desirable explosion-proof bottle caps of bottled drink, beer.

Claims

1. safety anti-explosive bottle cap, it is characterized in that: be depressed into few 1 hole (2) in bottle cap (1) upper punch, be depressed into the otch (4) that intersect at few 2 centers in bottle cap in-to-in plain cushion (3) upper punch, to not cut off, keep the connecting bridge thickness A, otch (4) must correspond in the middle of the hole (2) on the bottle cap (1).
