Abstract

The utility model provides a multilayered film insulated bag, include: an outer film, an intermediate level film, with outer film connect and outer film with form a first clearance between the film of intermediate level, the intermediate level film is the foaming film, an internal layer film, with the intermediate level film connect and internal layer film with form a second clearance between the film of intermediate level, first clearance with the second clearance all is sealed. The utility model discloses a multilayered film insulated bag adopts multilayered film to keep warm, and reduce cost saves a large amount of storage spaces, repeatedly usable, and the practicality is the environmental protection again.

Description

Plural layers insulated bag

Technical field

The utility model relates to a kind of insulated bag, espespecially a kind of plural layers insulated bag.

Background technology

Current insulated bag, mainly adopts expanded polyethylene foam or foam to be incubated, not foldable of the expanded polyethylene foam of this kind of insulated bag, or larger to the injury of expanded polyethylene foam after folding, thus cause taking up room of this kind of insulated bag large, be difficult for storing. And this kind of expanded polyethylene foam be expendable, use and just can not carry out secondary use later, cause environmental pollution, cost is high, is difficult for popularization.

Therefore, be necessary to design a kind of new insulated bag, to overcome the problems referred to above.

Summary of the invention

The problem facing for background technology, the plural layers insulated bag that the purpose of this utility model is to provide a kind of can be reused, environmental pollution is few.

For achieving the above object, the utility model adopts following technological means: a kind of plural layers insulated bag, comprising: an outer membrane; One intermediate layer film, be connected with described outer membrane and described outer membrane and described intermediate layer film between form one first gap, described intermediate layer film is foamed thin sheet; One internal layer membrane, be connected with described intermediate layer film and described internal layer membrane and described intermediate layer film between form one second gap; Described the first gap and described the second gap all seal.

Further, the toughness of described outer membrane is greater than the toughness of described intermediate layer film and described internal layer membrane.

Further, described intermediate film is a kind of foamed thin sheet.

Further, described internal layer membrane is a kind of film that can be used for food.

Further, described outer membrane is to be formed by multiple films.

Further, described intermediate layer film is to be formed by multiple films.

Further, described internal layer membrane is to be formed by multiple films.

Compared with prior art, the utlity model has following beneficial effect: plural layers insulated bag of the present utility model adopts plural layers to be incubated, and reduces costs, and saves a large amount of storage spaces, and reusable, practicality is environmental protection again.

Brief description of the drawings

Fig. 1 is the cutaway view of plural layers insulated bag of the present utility model.

The drawing reference numeral explanation of detailed description of the invention:

Outer membrane	1	The first gap	4	Internal heat	7
						Intermediate layer film	2	The second gap	5
Internal layer membrane	3	External heat	6

Detailed description of the invention

For ease of better understanding the purpose of this utility model, structure, feature and effect etc., the utility model is described in further detail with detailed description of the invention by reference to the accompanying drawings.

As shown in Figure 1, plural layers insulated bag of the present utility model, the intermediate layer film 2 that comprises outer membrane 1, is connected with described outer membrane 1, the internal layer membrane 3 being connected with described intermediate layer film 2.

As shown in Figure 1, the good toughness of described outer membrane 1, intensity is large, to its protective effect of interior items. By multiple, individual film forms described outer membrane 1, this film can be identical can be also to select as required different films.

As shown in Figure 1, described intermediate layer film 2 is connected with described outer membrane 1, and between described intermediate layer film 2 and described outer membrane 1, form one first gap 4, described the first gap 4 is enclosed and forms with described outer membrane 1 by described intermediate layer film 2. Described intermediate layer film 2 is a kind of foamed thin sheets, has the effect that good obstruct heat is transmitted. By multiple, individual film forms described intermediate layer film 2, this film can be identical can be also to select as required different films.

As shown in Figure 1, described internal layer membrane 3 is connected with described intermediate layer film 2, and described internal layer membrane 3 forms one second gap 5 with described intermediate layer film 2, and described the second gap 5 is enclosed and forms with described intermediate layer film 2 by described internal layer membrane 3. Described internal layer membrane 3 is a kind of films that meet food hygienic standard, and contacted article are reduced to pollution to the full extent. By multiple, individual film forms described internal layer membrane 3, this film can be identical can be also to select as required different films.

As shown in Figure 1, the mechanism of heat insulation of plural layers insulated bag of the present utility model is: external heat 6 produces by Air Flow and contacting of outer membrane 1 effect that heat is transmitted, in the time that external heat 6 is delivered to the first gap 4 between outer membrane 1 and intermediate layer film 2, because described the first gap 4 seals, Air Flow performance is herein poor, effectively stop external heat 6 to transmit to intermediate layer film 2, and described intermediate layer film 2 foamed thin sheet that is a kind of effects with good barrier heat, the external heat 6 that part is flowed into described the first gap 4 intercepts again, the heat that enters interior environment is reduced. in like manner, internal heat 7 also has under the acting in conjunction of intermediate layer film 2 at internal layer membrane 3 and the second gap 5, has effectively stoped heat outwards to run off, thereby has realized heat insulation function. this kind of plural layers insulated bag can, for dress vegetable and fruit, play good preservation, contains for frozen goods or hot article, has good heat insulation and preservation effect.

More than describing in detail is only the explanation of the preferred embodiment of the utility model, non-ly therefore limit to the scope of the claims of the present utility model, so the equivalence techniques that all this creation of utilization descriptions and diagramatic content are done changes, and is all contained in the scope of the claims of the present utility model.
