Abstract

The utility model relates to a sealed bottle cover for container used for packaging, and is applicable to the seal of the container mouth for containing liquid with a certain pressure. The utility model is formed by nontoxic plastic injection molding, the structure comprises an inner cover and an outer cover, when the screws of the outer cover screw in the hollow inside of the inner cover, the inner cover is enlarged and generates large expansive force, so as to achieve the effect of high seal. The bottle cover can be used for many times, and in addition, the sealed outer cover of the container can be made into artwork ornaments, the utility model has the advantages of simple structure and convenient opening, and general minitype plastic unit can all produce.

Description

Sealed bottle cover for container

The utility model belongs to the packing container sealed product.Be applicable to and adorn the sealing that various liquid have the certain pressure container entrance, relate to the convenient nonexpondable bottle cap of a kind of unlatching.

Being used for carrying liquid Packaging Bottle cover at present adopts sheet tin lid usually, and the iron sheet grommet cover use the mechanical cap bottle cap, and this Bottle ﹠ Can covers and can only use once, will be during unlatching by instrument, and fragile Bottle ﹠ Can mouth.Another kind is the rubber bottle cap, plastic bottle closure, and yielding, leak tightness is poor, unsuitable splendid attire effumability liquid.

The purpose of this utility model is to adopt non-poisonous plastics, is injection molded into a kind of Bottle ﹠ Can lid of special structure form.Not only can satisfy the pressure-resistant seal packing requirements of pressure bottle cover, can not seal at any time and open conveniently by instrument, can nonexpondable seal cover cap.Overcome the sheet tin lid, the above-mentioned shortcoming of plastics, serum cap.

The utility model seal of vessel bottle cap is divided into two parts, is made up of enclosing cover and inner cap.Its shape of inner cap and bottleneck coincide, but inner hollow, and lid is gone into bottleneck inside, with the bottleneck inwall as the working effect face.The requirement that the shape of enclosing cover can be carried out multiple style with the need changes.But in harness agent structure exactly likes a screw, when the screw of enclosing cover screws in inner cap hollow inside, the inner cap bore is increased, and has produced expansive force, reaches the leak free effect.

The utility model description of drawings:

Figure 1 shows that sealed container structure figure.

Figure 2 shows that enclosing cover: (1) is screw for spin arm (2) among the figure.

Figure 3 shows that inner cap: (3) are endoporus among the figure, and (4) are interior capping, and (5) stretch face for inner cap.

The utility model airtight lid for container is achieved in that by enclosing cover 2 and Nei Gai 3 and forms. Will Interior hole (3) in screw in the enclosing cover (2) screws in the lid 3 a little, make inside and outside lid the into as a whole interior lid is pressed into bottleneck, because interior lid is a bit larger tham bottleneck, face coincide in the outer rim of interior capping (4) and the bottleneck, so certain sealing (interior cover strip can be gone out but firmly dial enclosing cover spin arm (1)) is arranged, and spin arm (1) turns clockwise. If interior lid rotates thereupon, lid stretching, extension face (5) in available hand or the instrument when mechanical cap is covered are fixing. Screw (2) rotates into the interior hole of interior lid (3), the internal diameter in interior hole (3) is squeezed swells, make interior lid produce certain pressure to bottleneck, enclosing cover screw (2) all enters interior hole (3), make wall friction in interior capping (4) and the bottleneck, reached the sealing effect.

The utility model sealed bottle cover for container can bear 2-4 atmospheric pressure by the test proof in the bottle, leakage body and gaseous phenomena can not occur. During unlatching, be rotated counterclockwise enclosing cover spin arm (1), screw (2) is withdrawed from, interior hole (3) internal diameter in the interior lid restores, and pressure reduces between the interior face of interior capping (4) and bottleneck, and the contact friction reduces, and stirs enclosing cover spin arm (1) and can take Nei Gai out of.

The utility model airtight lid for container embodiment:

Inner cap adopts elastomeric material preferably, and enclosing cover adopts the stronger material of hardness, and as non-poisonous polyethylene plastics, all injection mo(u)lding gets final product.Enclosing cover also can be made artwork ornaments.Because structure design novelty, be applicable to the sealing of bottled containers such as various drinks, liquid medicine class, carbonated beverage, because energy repeated use, gassiness drinks, beverage are once unspent, after building, can wait until next time and use, still keep original look, flavor, gas, so bottle cap is applicable to and contains the higher bottle of air pressure.The utility model adopts non-toxic plastic through mold injection molding, and production technology is simple, and the bottle cap quality is pliable and tough, low cost of manufacture, and general small plastic unit all can produce.

Claims

1, a kind of seal of vessel bottle cap is made up of enclosing cover 2, inner cap 3, it is characterized in that inner cap, enclosing cover are two parts, is combined into an integral body by screw (2), with the bottleneck inwall as the working effect face.
