Abstract
The utility model relates to a sealing internal cover for nonmetallic vessel, particularly a sealing internal cover of an aluminium foil composite bottle cover. The utility model is characterized in that an aluminum foil layer and a paper board are combined by bonding by a layer of wax type paste layer; the surface of aluminium foil layer is compounded with polyethylene, or polypropylene, or polystyrene, or polyvinyl acetate, or other modifiers, forming a holt melt layer, so a layer of compounded film is formed on the surface of the aluminium foil layer; the surface of the paper board is coated with a waterproof layer made of macromolecular material which increases aquosity.
Description
The utility model is the inner cap that a kind of nonmetallic vessel seals, particularly the improvement of aluminium foil Composite bottle cap inner sealing lid structure.
Name is called No. 95244999.4 Chinese patents of " the compound inner cap of aluminium foil paper mold ", discloses the compound inner cap of a kind of aluminium foil.Its structure is made up of by lining cement is bonding foil laminated film and paper mold; Wherein form sealing film and aluminium foil is formed foil laminated film by the aluminium foil surface coating adhesive.The inner cap of this structure can not guarantee a bottle interior medicine initial quality.Because foil laminated film and paper mold are bonding by the gluing lining cement,, so just exist solvent residues, its sanitary condition to be difficult to guarantee inevitably for forming sealing film again at the aluminium foil surface coating adhesive; Again since paper mold without any water-proof function, easily the moisture absorption causes paper mold cracking, layering, time one is long even go mouldy.Behind bottleneck Kaifeng, paper mold medicine direct and in the bottle contacts, and very easily pollutes medicine; As medicine is liquid, and the dirt in the bottle in the liquid adsorption paper mold can cause the liquid gelatinization.The cost of this inner cap is also higher.
The purpose of this utility model is the shortcoming that overcomes the compound inner cap structure of above-mentioned aluminium foil, and a kind of aluminium foil Composite bottle cap inner sealing lid of new construction is provided.
The purpose of this utility model is to realize like this.
Aluminium foil Composite bottle cap inner sealing lid, aluminium foil layer 2 and paper mold 4 bond together by wax class adhered layer 3.
But at the surface of aluminium foil layer 2 composite polyethylene, or polypropylene, or polystyrene, or polyvinyl acetate, or and modifier, form hot melt layer, promptly have one deck laminated film 1 at aluminium foil surface.Decide the materials used of inner cap according to the material of bottle use.If what bottle adopted is polythene material, then inner cap also adopts polythene material.
Can scribble the waterproof layer 5 of hydrophobicity High molecular material on the surface of paper mold 4.
The utility model adopts wax class adhered layer bonding between aluminium foil layer and paper mold, and at the surface recombination polyethylene of aluminium foil layer, or polypropylene, or polystyrene, or polyvinyl acetate, or and modifier, form hot melt layer.The laminated film that hot melt forms and bonding with wax does not have any solvent residues, has so just avoided solvent residues to pollute the problem of medicine.Scribble the waterproof layer of hydrophobicity High molecular material on the surface of paper mold, make the paper mold can the moisture absorption, also a series of problems with regard to not causing paper mold to take place because of suction.The utility model has been avoided solvent contamination, and safety and sanitation have guaranteed original quality of medicine; Manufacturing cost is also lower.
The utility model is provided by following embodiment and accompanying drawing thereof.
1 laminated film, 2 aluminium foil layers, 3 wax class adhered layers, 4 paper molds, 5 waterproof layers.
Accompanying drawing is the utility model structural representation.
Embodiment: aluminium foil Composite bottle cap inner sealing lid, aluminium foil layer 2 and paper mold 4 bond together by wax class adhered layer 3; At the surface recombination polyethylene of aluminium foil layer 2, form hot melt layer, promptly had one deck laminated film 1 on the surface of aluminium foil.Scribble the waterproof layer 5 of hydrophobicity High molecular material on the surface of cardboard 4.
Claims (3)
1, a kind of aluminium foil Composite bottle cap inner sealing lid includes aluminium foil layer 2 and paper mold 4,, it is characterized in that aluminium foil layer 2 and paper mold 4 bond together by wax class adhered layer 3.
2, according to the described aluminium foil Composite bottle cap of claim 1 inner sealing lid, it is characterized in that surface recombination polyethylene at aluminium foil layer 2, or polypropylene, or polystyrene, or polyvinyl acetate, or and modifier, form hot melt layer, promptly have one deck laminated film 1 at aluminium foil surface.
3,, it is characterized in that scribbling the waterproof layer 5 of hydrophobicity High molecular material on the surface of cardboard 4 according to claim 1,2 described aluminium foil Composite bottle cap inner sealing lids.
