Abstract
The utility model discloses a one-way breathable type sealing gasket, which is formed through combining an EVA foamed sheet and a one-way breathable film, wherein the EVA foamed sheet is pricked with breathable holes, and the EVA foamed sheet and the one-way breathable film are combined by adopting powerful adhesive. The one-way breathable type sealing gasket can achieve bottle mouth sealing, leads bacteria impurities in external air and the like not to enter a bottle, also can discharge gas in the bottle simultaneously, and is suitable for inclusions which can produce gas in long time sealing.
Description
Technical field
The utility model belongs to the packing technique field, relates to a kind of unidirectional ventilative formula seal gasket.
Background technology
In daily life, many fields all can relate to the packing of sealing, for example food, cosmetics and medicine field etc., and the kind of seal gasket has various ways, at different package contents, need to select different seal gaskets, so, still need and research and develop out more seal gasket, to adapt to the demand in market.
In view of this, the inventor relies on the needs in professional knowledge and market, and the structure of seal gasket is studied, and develops a kind of unidirectional ventilative formula seal gasket, and this case produces thus.
The utility model content
The purpose of this utility model is to provide a kind of unidirectional ventilative formula seal gasket, has grown the inclusion that can produce gas to be suitable for the time of sealing, and effectively realizes leak tightness.
To achieve these goals, solution of the present utility model is:
Unidirectional ventilative formula seal gasket is composited by EVA (ethene-vinyl acetate Bipolymer) foam sheet and one-way ventilating film, and pricking on the EVA foam sheet has breather hole, adopts potent adhesives to carry out compound between EVA foam sheet and the one-way ventilating film.
Diameter≤the 0.5mm of breather hole on the described EVA foam sheet, quantity≤10.
Respectively there is one deck one-way ventilating film on the upper and lower surface of described EVA foam sheet.
Described one-way ventilating film adopts through the film after the precise and tiny punching processing.
After adopting such scheme, the utility model is filled in the bottle cap as the press seal pad, behind the locking lid, the liquid or solid inclusion there is good sealing effectiveness, but gas can see through this pad and circulate, can guarantee equilibrium of pressure that bottle is inside and outside and oxygen balance or the carbon dioxide balance that helps some specific inclusion, also can make aqueous vapor see through pad and can not be condensed on bottle wall.The utility model had both reached the sealing bottleneck, made the airborne bacteria impurities etc. of outside can't enter in the bottle, can allow the gas in the bottle discharge simultaneously again, was suitable for the time of sealing to have grown and can produce the gas inclusion.
Below in conjunction with the drawings and specific embodiments the utility model is done further and to be elaborated.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the birds-eye view of the utility model EVA foam sheet.
Label declaration
One-way ventilating film 2
The specific embodiment
As depicted in figs. 1 and 2, the unidirectional ventilative formula seal gasket that the utility model discloses is composited by EVA foam sheet 1 and one-way ventilating film 2.Pricking on the EVA foam sheet 1 has breather hole 11, specifically, and the diameter≤0.5mm of breather hole 11, quantity≤10.It is compound to adopt potent adhesives (generally adopting polyurethane adhesive) to carry out between EVA foam sheet 1 and the one-way ventilating film 2, and this embodiment respectively has one deck one-way ventilating film 2 on the upper and lower surface of EVA foam sheet 1.The one-way ventilating film adopts through the film after the precise and tiny punching.
Wherein, prick out some breather holes on the EVA foam sheet 1, to reach ventilative purpose, after pad carries out stamping-out according to the bottle cap size, put into bottle cap, can form sealing effectiveness after the locking closure locking, because EVA foaming elasticity is fine, therefore can fill out the space in the middle of bottle cap and the bottleneck very full, form the leak free interlayer.And the gas that one-way ventilating film 2 produces inclusion can penetrate bottle by the breather hole 11 on one-way ventilating film 2 and the EVA foam sheet 1 at an easy rate, and by the one-way ventilating performance of one-way ventilating film 2, make the bacteria impurities of carrying secretly in exterior gas of bottle and the gas enter bottle interior by one-way ventilating film 2, can not exert an influence to inclusion, thereby reach ventilative but still leak free effect.
This pad does not need electromagnetic induction heating to seal, and can reach sealing, does not allow extraneous gas enter bottle interior, can allow bottle interior gas penetrate bottle by pad again, and suitable inclusion is easy to generate the material of gas.
The above is preferred embodiment of the present utility model only, is not the qualification to the utility model practical range, and all variation and modifications of doing according to key points in design of the present utility model all fall into its protection domain.
