CN2288142Y - Explosion-proof beer bottle cover - Google Patents

Abstract

The utility model provides an explosion-proof beer bottle cover. The cover face is provided with a groove or a mark. The compression strength of cover face part positioned in the range of the groove or the mark is lower than the compression strength of a beer bottle, and thereby, the explosion of the beer bottle of glass bottles is effectively prevented from occurring. The utility model has the advantages of simple structure, convenient production, low cost, etc.

Description

The explosion-proof beer bottle cap

The utility model relates to a kind of glass bottle beer bottle cap, belongs to beer or pressure container bottle cap field.

At present, glass bottle beer does not generally have measures for the prevention of explosion, and is higher or the beer bottle blast easily takes place when strenuous vibration takes place and casualty accident all causes damage to customer's personal safety and manufacturer's reputation in temperature.

Chinese patent CN2210863 discloses a kind of explosion-proof beer bottle cap, it is to have to jump the hole seam on capping, and between capping and gasket seal, accompany an aluminium backing, aluminium backing compressive strength is lower than the compressive strength of beer bottle, when gaseous tension in the bottle during greater than aluminium backing compressive strength, aluminium backing is broken through, by jumping the hole seam gas is discharged, prevent the beer bottle blast, but because the hole of jumping seam is arranged, thus there is antihygienic shortcoming, and aluminium backing is in process of production, when bottle cap is withheld at bottleneck, crushed or produced slight crack easily.

The purpose of this utility model is in order to overcome above-mentioned the deficiencies in the prior art part, to design a kind of explosion-proof beer bottle cap that can prevent the beer bottle blast.

The technical solution of the utility model is on the bottle cap that existing capping, gasket seal and clinching circle are formed, and capping is engraved groove or trace, and the degree of depth of groove or trace is less than capping thickness.Suitably select the degree of depth of groove or trace, make the compressive strength of this groove or trace be lower than the compressive strength of beer bottle.When pressure of the inside of a bottle during greater than the compressive strength of groove or trace, groove or trace are crushed, and capping is carved with groove or the trace part is washed open, and gas is released in the bottle, and pressure decay is avoided explosion accident.

The shape of this groove or trace can be to be twice or the multiple tracks straight-line groove or the trace of point of crossing with the cover center.

This groove or trace can also be osed top circle or polygon or other osed top shapes not.

In case of necessity, also can be on a capping with these several combination of shapes.

Be added with the ring seal pad of a hollow between capping and bottleneck, like this, pressure of the inside of a bottle can act directly on the capping, thereby prevents the beer bottle blast more effectively.

The utility model can prevent effectively that beer bottle from blasting, and avoids the generation of casualty accident.The beverage bottle cap that the alternative existing beer bottle cap of this explosion-proof beer bottle cap or other can produce pressure uses, have simple in structure, convenient for production, the advantage that cost is extremely cheap.

Accompanying drawing 1 is an explosion-proof beer bottle cap structural representation.

Accompanying drawing 2 is the capping scheme drawings that are carved with straight-line groove or trace.

Accompanying drawing 3 is the capping scheme drawings that are carved with closed circle groove not or trace.

Accompanying drawing 4 is the capping scheme drawings that are carved with straight-line groove or trace and non-closed circle groove or trace.

Accompanying drawing 5 is the capping scheme drawings that are carved with straight-line groove or trace and do not seal tetragonal groove or trace.

Below in conjunction with description of drawings embodiment.

Referring to Fig. 1, capping 3 inboards of existing beer bottle cap can be engraved groove or trace 2 aborning, add gasket seal 1, on bottleneck, the degree of depth of groove or trace 2 should be less than the thickness of capping 3 by 4 fastenings of clinching circle, and groove or trace 2 can be V-slots, also can be concave grooves.Gasket seal 1 is opened empty annular for the center, and pressure of the inside of a bottle is acted directly on the capping 3.As long as suitably select the degree of depth of groove or trace 2, make its compressive strength be lower than the compressive strength of beer bottle, when gaseous tension in the bottle during greater than the compressive strength of groove or trace 2, groove or trace 2 break, the capping part that is in groove or trace 2 scopes is washed open, and gas is gone out, and pressure of the inside of a bottle reduces, prevented the beer bottle blast, guaranteed personal safety.

Referring to Fig. 2, the shape of groove or trace 2 can be to be the criss-cross of point of crossing with the cover center on the capping 3.Referring to Fig. 3, but also osed top circle not of the shape of groove or trace 2.Leave not osed top part, can ensure when beer bottle cap is in capping part in groove or trace 2 scopes and is broken through, can not fly out and hurt sb.'s feelings.Referring to Fig. 4, Fig. 5, but the shape of groove trace 2 can also be criss-cross with closed circle not or not seal quadrangle and combine.
