Abstract

The explosion-proof structure of beer bottle and similar container includes bottle body, bottle cap and gasket seal. It is characterized by that on the bottle cap there is a pressure relief hole, and inside the bottle cap and between the bottle cap and gasket seal a decompression explosion-proof piece is mounted. Said decompression explosion-proof piece is made up by adopting aluminium-plastic composite film or aluminium, plastic and paper composite film or zinc-aluminium composite film. When the internal pressure exceeds the designed value of beer bottle, the decompression explosion-proof piece is automatically broken, the internal pressure is released through the decompression hole. When drinking the beer, the suction tube can be inserted into bottle through the dicompression hole and explosion-proof piece.

Description

The blast resistance construction of beer bottle and similar containers

The present invention relates to a kind of blast resistance construction of Bottle ﹠ Can class pressure container, particularly relate to the blast resistance construction of a kind of beer bottle and similar containers.

Beer is a kind of alcoholic beverage that people like.Because of it is a kind of air containing fluid, can in container, produce certain pressure, therefore its packing material is had than exacting requirements.For a long time, beer industry both domestic and external adopts glass bottle packaging beer always.The ordinary beer bottle structure as shown in Figure 1, it is made up of bottle 1, bottle cap 2 and packing seal 3.Although the glass wine bottle abundant raw materials, production technology is simple, and is inexpensive, owing to have certain pressure in the beer bottle, therefore also just has certain explosion hazard.Though the beer bottle of producing in the market and using all is according to standard specification production, its physicochemical property, as internal stress, thermal shock resistance, impact resistance, internal pressure resistance etc. exacting requirements is arranged all, particularly its internal pressure resistance is defined as 〉=1.2MPa, and every batch of product all will carry out strict inspection according to the rules, just can produce use after qualified.But in actual life, we still can often see the report that relevant explosion of beer bottle is hurted sb.'s feelings.Prevent that at present beer bottle from producing the method for exploding and mainly containing two kinds, a kind of is the compressive resistance that increases container, as improves its safety factor; Another kind is that safety device is set is explosion-proof with pressure limiting.Above-mentioned two kinds of safety anti-explosive methods all have application in the production of various pressure containers is used, a kind of method before beer bottle then only adopts mostly at present is its regulation bigger safety factor (K ≈ 2).However, because beer bottle is glasswork, its less stable, and compressive resistance has certain limit, in the production use such-and-such incident violating the regulations can take place, thereby explosion injury people incident can't be solved fundamentally in addition.Except the blast problem, also there is the another one problem in existing beer bottle, and Here it is, and bottle cap is opened problem.Because existing beer bottle cap all is to be pressed on the bottleneck by capsuling machine, during drinks beer, need just can open with special-purpose device for releasing closures, and when not having device for releasing closures at one's side, someone also stings out it with tooth, or removes by means of apparatus on every side, so very easily causes the damage of tooth or other apparatus.The existing the problems referred to above of beer bottle and similar containers thereof not only directly influence the safety of beer drinking person, and can have influence on the development of beer industry self.

The objective of the invention is to provides the blast resistance construction of a kind of beer bottle and similar containers for solving beer bottle or similar pressure container may produce the problem of explosion hazard and beer bottle because of a variety of causes in the production use difficult unlatching problem simultaneously.

For achieving the above object, beer bottle provided by the invention and similar containers blast resistance construction comprise bottle 1, bottle cap 2 and packing seal 3, it is characterized in that having relief hole 21 on described bottle cap 2, and pressure-relief explosion-proof sheet 4 is housed between bottle cap inner seal pad and bottle cap.

Described pressure-relief explosion-proof sheet 4 adopts aluminium, moulds complex film, aluminium, mould, paper complex film or zinc, aluminum composite membrane make, and also can adopt other materials similar to make.Its design compressive resistance value is less than beer bottle compressive resistance value.This complex film is similar to the film that seals that the soft beverage packing box suction pipe is inserted the entrance, and its thickness is determined according to design compressive resistance value.It promptly has higher compressive resistance, and as easy as rolling off a log again wearing out, thereby during drinks beer, can directly suction pipe be drunk after relief hole 21 places insert drunk after also pointed object such as available toothpick punctures.Stab an aperture with things such as suction pipe or toothpicks on burst disk, shake beer bottle then, pressure of the inside of a bottle is increased, beer will spray from aperture, makes it can be used for various celebrating occasions.

The present invention has thoroughly solved the blast problem of beer bottle or similar pressure container, fundamentally eliminated their potential explosion hazard, make beer bottle really reach safe and reliable requirement, and can replace existing beer bottle thus and become its renewal product.The present invention has simultaneously also solved the problem that existing beer bottle need could be opened by bottle opener, people need be by any instrument, also not needing to remove bottle cap just can be as drinking the soft beverage packing drinks beer, people are worried for can not find bottle opener never again, also can not remove to sting bottle cap with tooth again.In addition, the beer bottle of new construction is also owing to can be used for various celebrating occasions by spray foam.The present invention only needs to improve slightly and can produce original production technology, and material and other cost increase are seldom, thereby implements easily and have a promotional value widely.

The invention will be further described below in conjunction with drawings and Examples.

Fig. 1 is existing beer bottle structural representation.

Fig. 2 is a beer bottle integral structure scheme drawing of the present invention.

Fig. 3 is beer bottle of the present invention and similar containers blast resistance construction scheme drawing.

As shown in Figure 2, the blast resistance construction of beer bottle of the present invention and similar containers is arranged on the bottle cap, i.e. the present invention improves the ordinary beer bottle cap becomes explosion-proof bottle cap.This blast resistance construction as shown in Figure 3, it is that central authorities at the crown cap 2 of ordinary beer bottle stamp out the circular relief hole 21 that a diameter is D, aperture D determines that by theory design and test its preferred values is about 10mm.Between inboard original latex packing seal 3 of bottle cap and bottle cap, a slice pressure-relief explosion-proof sheet 4 is housed, relief hole 21 is sealed by Sheet Metal Forming Technology.This burst disk by aluminium, mould complex film, aluminium, mould, paper complex film or zinc, aluminum composite membrane make, and also can adopt other materials similar to make.Preferred aluminium in this example, mould complex film and make burst disk.Its design compressive resistance value is less than beer bottle compressive resistance value, and the thickness of burst disk determines that according to its design compressive resistance value its preferred values is about 0.1mm.

The processing technology of blast resistance construction of the present invention is as follows: at first go out a circular relief hole 21 in ordinary beer bottle cap central authorities, then at the inboard punching press pressure-relief explosion-proof of bottle cap sheet 4, at the inboard casting latex packing seal 3 that drips of pressure-relief explosion-proof sheet, explosion-proof bottle cap promptly completes again.After installing beer the explosion-proof bottle cap that processes is adopted common process, the bottleneck that is pressed onto beer bottle bottle 1 by capsuling machine gets final product.

Principle of work of the present invention can be referring to Fig. 2, Fig. 3.There is certain pressure to exist in the normal beer bottle that uses, when it is heated or is subjected to vibrating, its internal pressure will increase, pressure-relief explosion-proof sheet 4 can be subjected to the effect of this pressure, and the zone facing to relief hole 21 is stressed weakness zone on the burst disk, stressed as the unit area in this zone is P, and the design compressive resistance of burst disk is P _X, then as P＜P _XThe time, 4 of burst disk produce distortion, can not break; As P 〉=P _XThe time, burst disk will be broken, and makes a bottle interior leak of liquid, and pressure disappears.Thereby stopped the generation of explosion accident.
