Abstract

The utility model relates to a safety bottle cover used for sealing an inflated liquid bottle. The safety bottle cover comprises a main bottle cover body and a pressure reducing hole arranged on the main bottle cover body. The size of the pressure reducing hole is in the range from phi 0.1 mm to the diameter of the bottle cover. The pressure reducing hole is fixed with a safety film. The bottle cover of the utility model is provided with the pressure reducing hole and thus when the pressure in the bottle is oversize, the safety film on the bottle cover is bottle cover firstly pushed apart to prevent people from being hurt by the explosion of the glass bottle.

Description

Resistant closure

The utility model relates to a kind of bottle cap, particularly relates to a kind of resistant closure that is used to seal the aerated liquid bottle.

Mostly the bottled beer bottle of Chu Shouing is the bottle that adopts simple glass to do in the market, even the factory that has adopts glass inferior to make in order to reduce cost, the bottleneck sealing then by the lid press seal of an iron sheet or liner rubber pad on bottleneck.Because the beer bottle glass wall thickness is inhomogeneous, perhaps beer bottle repeatedly reclaims use, perhaps owing to the collision of bottle in packed and transported, storage process, shaken, or sight directly shines, the pressure in the bottle increases so that glass wall to bear pressure capability low and blast.According to Chinese Consumers' Association's statistics, appealed the bottle beer blast problem in several years, accident in 1998 is still increasing, and the quantity of hurting sb.'s feelings accounts for 69% of all kinds of total amounts of hurting sb.'s feelings, and the number that disables accounts for 71.4% of the total amount that disables.This problem is demanded people urgently and is gone to solve.

The purpose of this utility model is to overcome the defective of prior art; blast for fear of splendid attire aerated liquid bottle; and the customer's that causes injury accident; in order to protect customer's personal safety; reduce the loss; thereby provide a kind of all kinds of fizzs of sealing Sheng, resistant closure of beer bottleneck of being applicable to.

The purpose of this utility model is achieved in that

The resistant closure that the utility model provides is by bottle cap body, on the end face of bottle cap body, have vent, the diameter of vent can be φ 0.1mm to the diameter range less than bottle cap, and in the position of the vent of bottle cap body inner top surface fixing one deck safety diaphragm, perhaps placing an elastic seal again on safety diaphragm encircles with O shape, perhaps put an elastic seal earlier with O shape ring, fix a safety diaphragm more thereon and form at the bottle cap body inner top surface.The material and the thickness of the selected safety diaphragm of wherein different bottle caps are to select according to the national standard of Bottle ﹠ Can internal pressure-resistant; Safety diaphragm is the film that commercially available elastic rubber-plastic composite material, elastic composite etc. are made.

Advantage of the present utility model is:

The utility model is being done little improvement to existing bottle cap production technology, inexpensive again, but the resistant closure of producing has the function of breaking automatically when the Bottle ﹠ Can internal pressure surpasses certain value, has avoided that internal pressure is excessive to cause that Bottle ﹠ Can bursts and consequent fatal accident.

Below in conjunction with drawings and Examples the utility model is described in detail.

Fig. 1-A is the top view of the utility model resistant closure.

Fig. 1-B is the section-drawing of the resistant closure shown in Fig. 1-A along A-A '.

Fig. 2-A is the resistant closure top view of another embodiment 2 of the present utility model.

Fig. 2-B is the section-drawing of the resistant closure shown in Fig. 2-A along B-B '.

Drawing is described as follows:

1-bottle cap body 2-vent

3-elastic seal O shape ring 4-safety diaphragm

Embodiment 1:

Make the resistant closure that a beer bottle is used by Fig. 1.

Its bottle cap body (1) and rubber seal O shape ring (3) all adopt the product of existing beer bottle manufacturer, but make vent (2) in the punching of the centre of bottle cap body (1), diameter is 5mm, safety diaphragm (4) is placed on bottle cap body (10) inner top surface and sealing O shape is encircled between (3), safety diaphragm is to select commercially available elastic composite for use, thickness for can bear pressure of the inside of a bottle less than 1.2Mpa to safety diaphragm greater than the material manufacture of beer expansion pressure.Embodiment 2:

Make the resistant closure of a carbonic acid soda bottle usefulness by Fig. 2, its bottle cap body (1) and elastic seal O shape ring (3) all adopt existing product, but in the punching of the centre of bottle cap body (1), make vent (2), diameter is 2mm, elastic seal O shape ring (3) be placed on bottle cap body (1) inner top surface and safety diaphragm (4) between, safety diaphragm is commercially available, its thickness for can bear pressure of the inside of a bottle less than 1.2Mpa to safety diaphragm greater than the material manufacture of carbonic acid soda expansion pressure.Embodiment 3:

In embodiment 2, remove elastic seal O shape ring, the vent of bottle cap body (1) is φ 10mm, the rubber-plastics material that safety diaphragm (4) adopts food industry to use, thickness are 1mm and are also used as sealing O shape ring that all the other are with embodiment 2.

Claims

1. a resistant closure comprises bottle cap body, it is characterized in that: on the end face of bottle cap body, have vent, and on the vent of bottle cap inner top surface fixing one deck safety diaphragm.

2. by the described resistant closure of claim 1, it is characterized in that: on the inner top surface of bottle cap body, place elastic seal O shape ring, and between the safety vent of elastic seal O shape ring and bottle cap body end face fixing one deck safety diaphragm.

3. by the described resistant closure of claim 1, it is characterized in that: safety diaphragm is fixed on outside the elastic seal O shape ring.

4. by the described resistant closure of claim 1, it is characterized in that: the hole size that wherein reduces pressure is that φ 0.1mm is to the bottle cap diameter range.
