CN2506559Y - Anti-counterfeit explosion-resistant wine bottle cap - Google Patents

Abstract

The utility model provides an anti-counterfeit explosion-resistant wine bottle cap, which can be used by matching with a wine bottle comprising a bottleneck provided with an outer protruding circular ring, and is characterized in that the bottle cap has a structure consisting of a cap top and a lower extending arc side. The center of the cap top is provided with a circular through hole corresponding to a circular opening of the wine bottle, and a circular sealing cushion is arranged between an inner top plane of the bottle cap and an end plane of the bottleneck. An anti-pressure resistance and explosion-resistant force of the sealing cushion formed by the matching of the material and the thickness is less than that of the anti-pressure resistance and explosion-resistant force of the wine bottle. A ring type shape of the bottle cap corresponding to the outer protruding circular ring of the bottleneck is in a state of tight covering. The outer protruding circular ring of the bottleneck is covered by the inwardly curved and contracted lower edge of the ring type side of the bottle cap in a sealing combination. The utility model can simultaneously achieve the anti-counterfeit and the explosion-resistant of the bottle packaging wine, and has the advantages of simple structure, safe and convenient using, and low cost.

Description

A kind of false proof explosion-proof bottle lid

Technical field

The utility model relates to anti-counterfeit container, a kind of specifically false proof explosion-proof bottle lid.

Background technology

There is two large problems in existing bottle of liquor, and the one, not false proof, some famous brand of wine is easily manufactured the fake in the mode of old bottled blue ruin by illegal speculator, leads the legitimate rights and interests of customer and infringement manufacturer into a trap; The 2nd, not explosion-proof, pressure was excessive when particularly bottled beer can be because of can, and overvibration in the transportation and storage is too high or too low for temperature, and automatic blast can take place, and jeopardizes customer's health safety.In the prior art bottle of liquor generally can only realize false proof or explosion-proof the two one of, can realize then complex structure of false proof, explosion-proof product simultaneously, productive costs is higher.Prior art has improvement, perfect necessity, increases new false proof, explosion-proof kind.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of improved false proof explosion-proof bottle lid is provided, and can realize the false proof and explosion-proof of bottle of liquor simultaneously, and simple in structure, easy to use, safe, does not damage bottle, and cost is lower.

The purpose of this utility model is achieved in that

A kind of false proof explosion-proof bottle lid has the supporting use of bottle of evagination annulus with bottle neck, it is characterized in that:

This bottle cap is the structure that caping and downward arc limit are arranged, and its caping central authorities have a manhole corresponding with the bottle round mouth;

The packing seal of one circle is housed between bottle cap inner top surface and bottle neck end face, and the material of sealing pad and thickness mate the compressive resistance explosion power of formed compressive resistance explosion power less than bottle;

The ring limit shape and the size of this bottle cap are corresponding with bottleneck evagination annulus, and in the tight state of lid, this lower edge, bottle cap ring limit curves inwardly contraction and bottleneck evagination annulus is overmolding to seal combination.

On the annular top surface of described bottle cap or ring lower edge, limit be provided with a pull-tab, the connecting portion of this pull-tab is communicated with the prefabricated easy-to-draw indentation line on the bottle cap side.

The material of described bottle cap is non-toxic plastic, aluminium, sheet metal.

The utility model has following actively useful effect:

1. this bottle cap center hole is sealed by packing seal, the material of sealing pad and thickness coupling and when the bottle internal pressure is excessive prior to the glass bottle step-down of exploding, thereby avoided the blast of glass wine bottle and steady the suffering from of hurting sb.'s feelings, thereby safe in utilization.

2. this bottle cap is provided with pull-tab and easy-to-draw indentation line, and it is convenient to open, and is that disposable destruction is opened; In case it is open, bottle cap just can not be used again, reaches false proof purpose, false proof reliable.

3. after this bottle cap was opened, the bottleneck of glass wine bottle can be not impaired or be broken.

4. the material of this bottle cap is plastics or aluminium or sheet metal, and simple in structure, productive costs is lower.

The specific embodiment

Please refer to Fig. 1, the utility model is a kind of false proof explosion-proof bottle lid, with bottle neck the bottle 1 supporting use of evagination annulus 101 is arranged, and it is characterized in that:

This bottle cap 3 is for there being the structure on caping and downward arc limit, and its caping central authorities have a manhole 301 corresponding with bottle round mouth 102;

The packing seal 2 of one circle is housed between bottle cap 1 inner top surface and bottle neck end face, and the material of sealing pad 2 and thickness mate the compressive resistance explosion power of formed compressive resistance explosion power less than bottle 1;

Ring limit 302 shapes and the size of this bottle cap 3 are corresponding with bottleneck evagination annulus, and in the tight state of lid, these 302 lower edges, bottle cap ring limit curve inwardly contraction and bottleneck evagination annulus 101 is overmolding to seal combination.

During enforcement, on the annular top surface of described bottle cap, (see Fig. 3, Fig. 4, Fig. 5) or encircle lower edge, limit (seeing Fig. 6, Fig. 7, Fig. 8) to be provided with a pull-tab 304 that the connecting portion of this pull-tab 304 is communicated with the prefabricated easy-to-draw indentation line 305 on the bottle cap side.

During enforcement, the material of described bottle cap 3 is non-toxic plastic, aluminium.When material was plastics, lower edge, described ring limit 303 used method of heating to curve inwardly contraction with 101 coatings of bottleneck evagination annulus; When material was aluminium, lower edge, described ring limit 303 used the mechanical stitch method to curve inwardly contraction with 101 coatings of bottleneck evagination annulus.

The material of described bottle cap 3 also can be used for example tinplate etc. of sheet metal.

The material of described packing seal 2 can be for rubber, flexible plastic, certain thickness aluminium foil etc. is arranged.
