Abstract

The invention provides a secondary-injection-molding inner plug of a wine bottle. The secondary-injection-molding inner plug of wine bottle comprises a liner 1, and an inner side contact part 2 of a bottle port. The secondary-injection-molding inner plug of the wine bottle is characterized in that the liner is formed by PP (Propene Polymer) material at food grade in a first injection molding way; and the inner side contact part 2 of the bottle port is formed by TPE (Thermoplastic Polyurethane Elastomer) soft material at food grade in a secondary injection molding way. The secondary-injection-molding inner plug of the wine bottle has the advantages that the inner side contact part 2 of the bottle port just can be contacted with the bottle port but not the wine through the secondary injection molding technology, so that the leakage can be avoided, and the problem of the deformation of the inner plug can be solved; and the liner 1 contacted with the wine cannot cause any variation.

Description

Quadric injection mould wine bottle inner plug

Technical field

The present invention relates to the wine bottle inner plug.

Background technology

Because ceramic wine bottle is by high-temperature firing, the bottleneck error is larger, and the phenomenon of seepage appears in hard material (LDPE) wine bottle inner plug easily that always use, is difficult to solve.

A kind of soft TPE was arranged in recent years, in a large number for the production of the wine bottle inner plug, effect is fine, can solve leakage problems, but find again to have flexible

inner plug contacts

1,2 year with wine after simultaneously the distortion reaction, have to be stained with and stick with paste sense, particularly the high wine changes in contact is larger, so market demand is a kind of can solve the interior plug that seepage can not exert an influence to wine again.

Summary of the invention

For the distortion that solves simple employing flexible inner plug existence, the problem of being stained with the paste sense, we have found the hard material mutually harmonious with the TPE food grade materials by repeatedly practising, designed a kind of wine bottle inner plug of unique shape, the soft or hard combination, adopt quadric injection mould, flexible material touches bottleneck can not touch wine, has solved seepage, interior plug problem on deformation.Hard material touches wine, and good stability can not exert an influence to wine.(hard material: food stage PP material, flexible material: food stage TPE material)

The quadric injection mould wine bottle inner plug of the present invention's design, comprise the inboard contact portion (2) of inner bag (1) and bottleneck, it is characterized in that: described inner bag (1) is for the first time injection mo(u)lding by PP material polypropylene food grade materials, the inboard contact portion of described bottleneck (2) is passed through for the second time injection mo(u)lding by TPE food stage flexible material, inner bag (1) has an outward extending circle limit (3) at bottle mouth position, the core of inner bag (1) has the stuck point that contacts with ceramic cap, and the inboard contact portion of the bottleneck of wine bottle inner plug (2) is screw insert by secondary injection molding.

The internal diameter that an example of above-mentioned wine bottle inner plug is the wine bottle inner plug is 13mm, and the band edge external diameter is 28mm, and the inboard contact portion 2 of the bottleneck of wine bottle inner plug is that the silk external diameter of screw insert is 21mm by secondary injection molding, the high 21mm of whole bottle stopper.

The design's advantage: 1, by the quadric injection mould technology, inner bag (1) does not contact with wine, and any variation can occur.

2, the inboard contact portion of bottleneck (2) touches bottleneck and can not touch wine, has both solved seepage, has solved again interior plug problem on deformation.

3, the wine bottle inner plug is combined with bottle cap firmly, can not come off.

The class of 4, attractive in appearance, environmental protection, raising bottle.
