Abstract
The utility model relates to a bottle cap, particularly an overpressure protecting bottle cap for beer bottles or other bottle class containers with pressure. The utility model comprises a cap top and a cap edge. A sealing gasket is arranged in the utility model. The cap top of the utility model is provided with a pressure releasing hole in order to prevent the accident that a person is injured by the explosion caused because the internal pressure in a bottle class containers exceeds the enduring ability of the container, and a pressure releasing sheet whose compression strength is lower than the compression strength of a bottle body is clamped between the inner side of the cap top and the sealing gasket. The utility model has the advantages of simple manufacture, easy popularization, etc.
Description
The utility model relates to a kind of bottle cap, in particular for the overvoltage protection bottle cap of beer bottle or other band pressure bottle type container.
Existing Bottle cap structure comprises caping, lid limit, has packing seal in the lid.When it is used as the mouth piece of bottle type container, if the interior dress of bottle is the medium that easily produces pressure, then because the suitable overvoltage protection measure of shortage; allow the people that a kind of sense of insecurity is always arranged; for example, the glass bottle of splendid attire beer is with regard to the Chang Yinwu overvoltage protection and the casualty accident of blasting.
For this reason, the purpose of this utility model is to provide a kind of bottle cap, and it can be in pressure pressure release voluntarily during near the compressive strength of container, to prevent the explosion injury people.
The technical scheme that realizes the utility model purpose is: a kind of bottle cap; overvoltage protection bottle cap in particular for beer bottle or other band pressure bottle type container; comprise caping, lid limit; has packing seal in the lid; its distinctive feature is: caping is provided with relief hole, clamps the pressure release sheet that compressive strength is lower than bottle between caping inboard and the packing seal.
And, the rounded or polygon of relief hole.
And caping posts shielding layer.
Like this,, just break, bottle interior too high pressure is released, thereby avoids the casualty accident that explodes at the cooresponding pressure release sheet of bottle cap relief hole place when the pressure in the bottle during greater than the pressure release sheet but less than the compressive strength of container.This bottle cap can be used for each type beer of splendid attire or other easily produces the bottle type container of the medium of pressure, and has manufacturing simply, is easy to advantages such as popularization.
The utility model is described in further detail below with reference to accompanying drawing.
Fig. 1 is the cutaway view of bottle cap.
Fig. 2～Fig. 4 is respectively the birds-eye view of Fig. 1.
With reference to Fig. 1, bottle cap described in the utility model comprises caping 1, lid limit 6, has packing seal 5 in the lid, and caping 1 is provided with relief hole 3, clamps the pressure release sheet 4 that compressive strength is lower than bottle between caping 1 inboard and the packing seal 5.Wherein, relief hole 3 is preferably rounded, also can be polygon, (sees Fig. 2～Fig. 4) as peripheries such as triangle, quadrangle, hexagons for the aperture of closed.Add man-hour, relief hole 3 can be one time punching molded with bottle cap, also can distinguish punching out.But described pressure release sheet 4 aluminium matter thin slices also can be plastics, and its compressive strength should be 70%～80% of bottle compressive strength, generally depends on its thickness.Hd top face is posted shielding layer 2, and this shielding layer 2 can be selected the pressure sensitive adhesive sheet for use, and its surface can be printed on pictorial trademark.
The technical program can be used for fastening formula bottle cap and screw thread screwing type bottle cap.
