Abstract
The utility model relates to an explosion-proof bottle cap, which comprises a bottle cap body and a sealing gasket. A cavity is arranged on the bottle cap body, the side wall of the cavity is provided with a vent hole, and a sealing body is arranged in the cavity. When internal pressure of a bottle exceeds normal pressure, gas in the bottle passes through the vent hole and a binding face of the side wall of the cavity and an elastic sealing body and automatically discharges, and gas pressure in the bottle is effectively prevented from continuously rising. In addition, ambient air can be prevented from entering the bottle because of pressing force of the elastic sealing body to the cavity, so explosion proof purpose is realized, and materials stored in the bottle are ensured not to deteriorate.
Description
The utility model relates to a kind of protectiveness cap shape lid that is used for mouth piece, specifically a kind of explosion-proof bottle cap.
Chinese patent literature is in the technical scheme of a kind of " explosion-proof beer bottle cap " that has been disclosing of CN2245040 with the notification number on January 15th, 97, this scheme is at bottle cap upper punch one aperture, and in bottle cap, install a sealing pressure release pad additional, when the pressure of the inside of a bottle superpressure, its sealing pressure release pad is broken through, and drains pressure in the bottle outlet with this.But there is following shortcoming in this kind structure: 1, after superpressure takes place, the gas in the bottle can with the outside air exchange of circulating, make that beer goes bad in the bottle, caused waste; 2, the size of the thin and thick of sealing pressure release pad and diameter that deflation hole is opened is the gordian technique of control pressure of the inside of a bottle, thereby has increased the difficulty of producing.
The purpose of this utility model is to provide the simple explosion-proof bottle cap of pressure, integral structure and manufacturing process in a kind of energy automatically regulating container for storing.
The purpose of this utility model is such realization: be provided with a cavity on the body of the bottle lid of equipped packing seal, and be provided with deflation hole on the sidewall of cavity, an equipped sealing member in the cavity.
Cavity is a ring-like cavity; the middle part of its annular cavity is the cylinder of a hollow; that the cross-sectional plane of its cavity can be is round, one of square, polygonal or petal-shaped structure; elastomeric sealing member is fitted in the cavity; its deflation hole is located at the top of cavity side walls, and is provided with a decoration protective cover on the outside face of body of the bottle lid.
The technological advance that the utility model is obtained: when pressure of the inside of a bottle surpasses normal pressure, be that pressure of the inside of a bottle is greater than the thrust of elastic sealed body to cavity side walls, gas in the bottle is discharged automatically by the binding face of deflation hole and cavity side walls and elastic sealed body, prevented that effectively the bottle internal gas pressure from continuing to raise, in addition, because elastic sealed body can stop outside air to enter in the bottle to the thrust of cavity side walls, thereby both realized explosion-proof purpose, guaranteed again that bottle interior institute storing matter never degenerated.
Be that embodiment further describes the utility model below with the accompanying drawing:
Fig. 1 is first embodiment of the present utility model.
Fig. 2 is another embodiment of the present utility model.
As shown in Figure 1: suppress the cavity 6 of a column type at the middle part of body of the bottle lid 1, the top of cavity 6 sidewalls is provided with deflation hole 2, and present embodiment deflation hole 2 is provided with two.Add in the cavity 6 and dash the elastic sealed body 3 that has elastomeric material to make, make it produce certain thrust cavity 6 sidewalls.Superpressure to take place in the bottle and to the decoration on bottle cap surface, adhere to a protective paper or plastic film 4 on the top layer of body of the bottle lid 1 in order to monitor, present embodiment is a plastic film 4, and can be printed on pattern or trade mark moulding on the chamber film 4.When superpressure occurring, over-pressure gas can back down plastic film 4 or push up bad, thereby it is too much both can to have warned bottle interior gas, should take corresponding measure.Also can be on plastic film 4 or elastic sealed body 6 coated chemical reagent, when superpressure occurring, the variable color that reacts of institute's exhaust body and reagent is warned with this.
Fig. 2 is another embodiment of the present utility model, itself and the foregoing description difference are, cavity 6 is a ring-like cavity, cavity 6 is around the cylinder 7 of a hollow form, the shape of its elastic sealed body 3 and cavity 6 match to be a ring-type and to place in the cavity 6, described cavity 6 also can be selected other shape for use, is structures such as round, square, polygonal or lace type as its cross-sectional plane.In order to make good sealing effect between bottle cap and bottle, the two is fitted with packing seal 5 at it.
