Description

A kind of glass

Technical field

The utility model belongs to a kind of drinking-water apparatus, relates to a kind of glass that has plastic housing, more specifically, is a kind of improvement about enclosed construction between plastic housing and the glass inner bag.

Background technology

In the prior art, drinking-water adopts plastic production with having.This plastic cup is owing to material, and the health to the person constitutes potential harm easily, and people have recognized this harm; And gradually it is sublated, generation again using glass, and glass is easily because of breaking or the explosion fragmentation; So people have covered plastic housing, the outer cover that especially adopts the PC material to process again in the glass outside; It has toughness, and is shock-resistant, can play the effect of protection to glass.The release of this glass more and more receives people's welcome.

At present; The glass that sell in market, adopt the structure of a kind of plastic housing and glass inner bag fit: glass inner bag is placed in the plastic housing more, lets the neck portion of glass inner bag stretch out from the mouth mouth of plastic housing; And the shoulder by glass inner bag is against the inner shoulder place of plastic housing; Between two shoulders, be lined with rubber washer,, glass inner bag be fixed among plastic housing and the plastic bottom cover by the bottom of plastic bottom cover sealing plastic housing.This glass is by the slit between rubber washer sealing plastic housing and the glass inner bag, in case solution stopping body or aqueous vapor get into the inside of plastic housing from the slit, simultaneously; Can also play shockproof, antihunt action to glass inner bag; But rubber washer system only relies on being adjacent between plastic housing and the glass inner bag to seal, because in use; Rubber washer exists regular displacement and deformation; Thereby occur easily having trickle slit owing to not fitting fully, letting aqueous vapor exist again and get into the inner possibility of plastic housing, its sealing is poor.

Summary of the invention

The purpose of the utility model is to overcome the deficiency of prior art and a kind of glass is provided; This glass improves the structure of rubber washer; And the design feature that proposes to utilize glass self strengthens the closure of rubber washer, to improve the sealing between plastic housing and the glass inner bag.

Its purpose is realized by following scheme:

A kind of glass comprises that glass inner bag is placed in the plastic housing, and the neck portion of glass inner bag is arranged in the neck portion of plastic housing; And the shoulder of glass inner bag is against the inner shoulder place of plastic housing; And the inner shoulder of the shoulder of glass inner bag and plastic housing is lined with rubber washer between the two, is closed in the bottom of plastic housing by plastic bottom cover, and glass inner bag is fixed among plastic housing and the plastic bottom cover; Be characterized in; The mouth mouth of glass inner bag is positioned at the below of plastic housing neck portion, and rubber washer inwardly is formed with shape and is inverted groove in top, and this groove can be placed in the edge of glass inner bag mouth mouth.

Like this, because the groove on rubber washer top can be placed in the edge of glass inner bag mouth mouth, therefore; Rubber washer is difficult for displacement and regular change takes place, importantly, and during installation; To the squeezing action of rubber washer lower end,, will make rubber washer obtain to stretch uniformly between plastic housing and the glass inner bag with the effect of lifting of the mouth mouth of glass inner bag to the rubber washer upper grooves; So; All can paste better between rubber washer and plastic housing, the glass inner bag, and make between plastic housing and the glass inner bag that in case slight variations slightly, rubber washer can be regulated automatically and adapt to; Therefore, the sealing property between plastic housing and the glass inner bag can be further improved.

Description of drawings

Fig. 1 is the structure cross-sectional schematic of a kind of specific embodiment of the utility model glass.

The specific embodiment

Below in conjunction with accompanying drawing the structure of the utility model is carried out detailed description:

With reference to Fig. 1, this glass comprises glass inner bag 1, plastic housing 2, rubber washer 3 and plastic bottom cover 4.Wherein, glass inner bag 1 has glass shoulder 11, glass neck portion 12, glass mouth mouth 13 and glass bottom 14; Plastic housing 2 has plastics shoulder 21, plastics neck portion 22; Rubber washer 3 has ring 31, inwardly is formed with shape in ring 31 tops and is inverted groove 32, and this groove 32 is placed in the edge of glass mouth mouth 13; Be placed in glass inner bag 1 by plastic housing 2; Let glass neck portion 12 be arranged in plastics neck portion 22, and be against the inboard place of plastics shoulder 21, and glass shoulder 11 and plastics shoulder 21 are pushing the ring 31 of rubber washer 3 between the two by glass shoulder 11; Plastic bottom cover 4 is closed in the bottom of plastic housing 2; By the feet 41 jack-up glass of plastic bottom cover 4 bottom 14, make the ring 31 of rubber washer 3 receive the pulling force of above-below direction and stretch, so; Ring 31 can paste better with glass inner bag 1, plastic housing 2 respectively, and its sealing property also obtains further raising.
