CN2135541Y - Multi-function thermal insulated bag - Google Patents

Abstract

The utility model relates to a multi-function thermal insulated bag which is composed of a bag body, a bag cover closely matched with the bag body, and a shoulder strap arranged on the bag body. The wall bodies of the bag body and the bag cover are made by folding material with a plurality of layers and different characters, the material layers comprises at least an inner waterproof plastic film layer, a middle heat insulation sandwich layer, a light reflection layer, and an outer waterproof decoration layer. The heat insulation sandwich layer can be made of foam or metal wool. The multi-function thermal insulated bag has functions of heat insulation, water proof, and light radiation proof.

Description

Multi-function thermal insulated bag

The utility model relates to a kind of insulation bag, the insulation bag or the case that particularly have multiple functions such as heat-insulation and heat-preservation, waterproof and anti-light radiation.

In daily life, people are freezed and cold insulation with refrigerator, heat and are incubated with electric heater, but, in wireless occasion, as during the journey or open-air, existing temperature holding device just can't use, even electricity is arranged, carrying that refrigerator etc. goes out also is inconvenience very.Therefore, people are studying always and are making a kind of portable multifunctional attemperator, satisfy multiple daily life needs, are with cold drink go out work or tourism in food, summer as being with winter, keep the fresh of the marine product bought and vegetables at a distance, existing this type of device mainly is to adopt the vacuum interlayer mechanism of heat insulation, and manufacturing materials is glass or enamel, and is very heavy and easily cracked.

The purpose of this utility model is will provide a kind of to have heat insulation, waterproof and radiation function against sunshine, and the multifunctional heat insulating bag of lightweight, portable.

For achieving the above object, multifunctional heat insulating bag of the present utility model adopts such structure, it comprises inclusion, can seal main body clad suitable for reading and be fixed in braces on the inclusion, difference from prior art is: the wall body of inclusion and clad is to make by the material of multilayer different qualities is superimposed, and these layers comprise innermost watertight layer, the thermal insulation layer of centre and the waterproof layer of reflector layer and outside at least.In an embodiment of the present utility model, each stacked system that the wall body of inclusion and clad is arranged from inside to outside forms: interior plastic film, metallic paper, foam layer, outer plastic film and surface decoration layer.In another embodiment of the present utility model, the wall body of inclusion and clad is made of the water-proof decorative layer of interior plastic film, space wadding (or claiming metal wool) interlayer and outside, and space wadding wherein has reflective and heat insulation double action.

Because the multilayer build-up of different qualities is formed the wall body of bag, and above-mentioned insulation bag of the present utility model has just possessed all characteristics of layers of material simultaneously, thereby can realize multiple functions such as heat insulation, waterproof and anti-light radiation.

Below in conjunction with embodiment and accompanying drawing thereof the utility model is described further.

Fig. 1 is that wherein clad closes according to the three-dimensional structure diagram of the multifunctional heat insulating bag that the utility model proposes.

Fig. 2 and 3 is amplification profiles of part of the wall body structure of reflection inclusion and clad, and they represent two embodiment of the present utility model.

As shown in Figure 1, this multifunctional heat insulating bag is made of inclusion 1, clad 2 and the braces 3 that is fixed on the inclusion 1, is connected with slide fastener 4 between a side of the clad (not shown) that links to each other with inclusion, other three sides and inclusion, so not only has been convenient to sealing but also is convenient to uncap.

If the wall body that is built up by multilayer material described below is very gentle light, then can establish a framework, wall body is fixed on the framework, if wall body has certain rigidity, also can directly make or bond and form clad and inclusion by wall body base material.

Fig. 2 illustrates the wall body structure of an embodiment of the present utility model, this wall body is from inside to outside formed by following each stacked closing: interior plastic film 11, reflecting metal paper tinsel 12, foam layer 13, outer plastic film 14 and dressing of a surface cloth 15, wherein plastic film is that anti-sealing has been seeped in the foam layer of heat-blocking action and goes.

Fig. 3 shows the wall body of another kind of structure, comprising inner plastic film 101, plays the space wadding interlayer 102 and the waterproof outer decorative layer 103 of heat-blocking action, and waterproof outer decorative layer 103 is used waterproof cloth, makes as rubber coating cloth.The space wadding interlayer 102 here plays heat insulation and reflective double action.For ease of direct store food, the inner plastic film preferably adopts non-toxic plastic.

Claims (1)

1. A kind of multifunctional heat insulating bag, it is made of inclusion, the clad that can cooperate with the inclusion sealing and the braces that is contained on the inclusion, its characteristic is that the wall body of inclusion and clad is formed by following three stacked closing at least: inner plastic film, the reflector layer of centre and the water-proof decorative layer of thermal insulation layer and outside.
