Abstract

The utility model relates to a thermos shell with the structure of the combination of metal and plastic. The thermos shoulder, bottom and a handle are molded by plastic and a metal pail is formed by rolling metal materials and a layer of plastic film is made through pyrocondensation on the surface of the metal pail. The utility model has the advantages of the shell which is made of metal or plastic and the bottom does not rust and has strong anti-impact force. The pyrocondensation film leads the color of the design to be more distinctive and the pattern to be richer. The utility model also has the advantages that the cost of raw materials is low and the manufacturing is very easy.

Description

Iron is moulded the vacuum flask shell of integrated structure

Technical field

The utility model relates to a kind of vacuum flask, refers in particular to the vacuum flask shell that a kind of iron is moulded integrated structure.

Technical background

At present, the vacuum flask shell that people generally use generally is to be made by homogenous materials such as metal or plastics.The characteristics of metal heat preservation bottle case are: specious, durable, but its fee of material is expensive, pattern printing cost height, outer casing bottom get rusty easily.The characteristics of plastic, thermal-insulation bottle case are: cheap, and non-corrosive, but its anti-impact force is poor, and the effect of outward appearance and pattern is undesirable, and long-term use can be faded or performance becomes fragile, so service life is short, commodity are of low grade.

Summary of the invention

The purpose of this utility model is: the vacuum flask shell that provides a kind of iron to mould integrated structure, its bottom non-corrosive, long service life, specious, pattern are printed easily, and with low cost.

For reaching the technical scheme that this purpose takes be: a kind of iron is moulded the vacuum flask shell of integrated structure, comprises moulding shoulder (1), metal bucket (2), moulding at the end (3) and mould (4), also comprises heat shrinkage film (5).Heat shrinkage film (5) pyrocondensation is at the outer surface of metal bucket (2), the top of metal bucket (2) and bottom respectively with mould shoulder (1) and mould at the end (3) by flanging with tighten seam and snap together, mould the top of (4) with mould shoulder (1) and be injected into one, mould the handle bottom of (4) and be screwed onto with metal bucket (2).

Compared with prior art the utility model has the advantages that:

1, durable in use: owing to be made of plastics at the bottom of the kettle, non-corrosive because metal bucket is made by metal material, has stronger anti-impact force again, therefore combines the advantage of the shell of being made by metal or plastics homogenous material, has prolonged service life.

2, specious: since the outer surface of metal bucket smooth, have metal-like, do not fade, never degenerate, therefore can keep its external form intact for a long time, again because pattern color distinctness, the graphics rich on heat shrinkage film, printed, increase varieties and designs easily, and give aesthetic feeling, improved the commodity class.

3, make easily:, therefore make easily because each manufacturing procedure all adopts existing conventional equipment and manufacturing process.

4, low price: because shell upper, bottom and mould adopting plastic injection-moulded forming, and metal bucket can adopt common galvanized iron, has reduced material cost, again because manufacture craft is simple, has reduced complete manufacturing cost.

The specific embodiment

As shown in Figure 1 and Figure 2, a kind of iron is moulded the vacuum flask shell of integrated structure, comprises moulding shoulder (1), metal bucket (2), mould at the end (3) and moulding (4), also comprises heat shrinkage film (5).Mould shoulder (1), mould at the end (3) and mould (4) and be formed by injection molding, the outer surface of heat shrinkage film (5) pyrocondensation of multicolour pattern in metal bucket (2) will be printed with, bending has flanging respectively in the top of metal bucket (2) and bottom, form respectively at the edge of moulding shoulder (1) and moulding at the end (3) and to tighten seam, then metal bucket is snapped together with moulding shoulder and mould the end, mould the top of (4) with mould shoulder (1) and be injected into one, mould the handle bottom of (4) and be screwed onto with metal bucket (2).The vacuum flask outer casing bottom non-corrosive of this structure, durable, specious, pattern is abundant, cheap, make easily.

Claims

A kind of iron is moulded the vacuum flask shell of integrated structure, comprises moulding shoulder (1), metal bucket (2), mould at the end (3) and moulding (4), it is characterized in that: also comprise heat shrinkage film (5); Heat shrinkage film (5) pyrocondensation is at the outer surface of metal bucket (2), the top of metal bucket (2) and bottom respectively with mould shoulder (1) and mould at the end (3) by flanging with tighten seam and snap together, mould the top of (4) with mould shoulder (1) and be injected into one, mould the handle bottom of (4) and be screwed onto with metal bucket (2).
