Abstract

The utility model relates to a daily product bag body, in particular to a cold insulation bag, which comprises a composite layer bag body, and is characterized in that: the composite layer bag body is formed by compounding an aluminum-plastic composite membrane, a reinforced PE film, a composite PE film, a heat insulating material, a composite PE film and an extruded composite membrane or lamination film. The cold insulation bag mainly solves the technical problems that the oxygen transmission rate is high and the sealing property is poor to cause poor cold insulation (heat preservation) effect due to material selection of the bag body, the strength of the bag body is insufficient, the durability of the bag body is poor, water seepage is easy to happen and the like of the conventional cold insulation bag, and has the characteristics of lightness and convenience, and convenient printing.

Description

A kind of cold-keeping bag

Technical field

The utility model relates to the daily living article bag, particularly a kind of cold-keeping bag.

Background technology

At present, people generally are to use common shopping bag when buying frozen foods, and its function only limits to loading and packing, can not be incubated, and transport frozen food is dissolved, and influence is edible.In view of the foregoing, the dealer has invented the sack with heat insulation function.As Chinese utility model patent specification sheets (Granted publication number: CN2300613Y) disclose a kind of cold insulation or thermal protective aid.It comprises: main bag, it is made of at least two layer materials, be external structure layer and the adiabatic layer in it, also comprise inside liner, main bag comprises bottom, wall on every side and top cover, and is provided with the switching mouth, also has the outer bag that fuses with main bag in the outside of main bag, diapire and wall all around should outer bag be arranged, and described outer bag inwall and container shapes are adaptive, and removable adjusting position, shape and container adaptive vertical dividing plate or spacer block are arranged.The external structure layer of making described Zhu's bag can use any suitable bagging, for example: cloth, thick cloth, canvas, synthetic fiber cloth; Adiabatic layer can use any soft thermal insulating material, and for example: the cotton-shaped material that cotton, hair, syntheticfibres or its compound are made also can be foamed plastic or other porous materials; Described inside liner can be any flaky material, for example: plastic film or synthetic film.It can play actv. cold insulation (insulation) effect.But said structure has following shortcoming:

1, because the material selection cause of bag, the oxygen permeability height of bag, leak tightness are poor, cause cold insulation (insulation) effect not ideal enough.

2, owing to the material selection cause of bag, the insufficient strength of bag, durability are not good, and the situation of infiltration takes place easily.

The utility model content

The purpose of this utility model is to provide a kind of cold-keeping bag, mainly solve existing cold-keeping bag because the material selection cause of bag, the oxygen permeability height of bag, leak tightness are poor, cause cold insulation (insulation) effect not ideal enough, and technical matterss such as not good, the easy generation infiltration of the insufficient strength of bag, durability situation also have characteristics light, that be convenient to print.

For achieving the above object, the utility model is achieved in that

A kind of cold-keeping bag, it comprises the composite bed bag, it is characterized in that: described composite bed bag ecto-entad successively by vacuum plated aluminum film, strengthen PE film, compound PE film, warm material, compound PE film, PE film and extrude compound or drench that film is compound to be formed.

Described cold-keeping bag is characterized in that: described bag mouth end links to connect and carries the hand band by carrying hand.

Described cold-keeping bag is characterized in that:

The described hand button of carrying comprises interior button and outer button; Described outer button inside face has button column respectively and extends to the microscler trough of belt of outer button upper end, also is provided with short button column in this trough of belt; Button has the button hole of position corresponding to outer button button column in described;

Offer the position on the described bag also corresponding to the perforation of button column, perforation corresponding to short button column is offered at the described hand band two ends of carrying respectively; Carry in the microscler trough of belt that hand band two ends are positioned outer button; Outer button button column pass after the perforation on the bag with interior button on button hole fasten.

Described cold-keeping bag is characterized in that: described short button column length is not more than the degree of depth of microscler trough of belt.

Described cold-keeping bag is characterized in that: described fastening regularly is distributed in around the trough of belt.

By said structure, advantage of the present utility model is:

One, composite bed Bag structure:

1, use composite bed Bag structure of the present utility model, can reduce the rate of supporting, increase leak tightness, strengthen heat-insulating property, increased bulk material intensity, durable, light, do not seep water, be convenient to print.

2, use composite bed Bag structure of the present utility model, can when the course of processing is handled, strengthen the feature of environmental protection.

Two, the hand structure is carried in combination:

1, use the utility model structure can make bag, bag carry the assembly operation convenience of hand, laborsaving.

2, use the utility model structure, the hand of carrying of bag, bag can be according to user's hobby, the length that hand is carried in selection.

3, use the utility model structure, the carrying hand and can pull down and clean of bag, bag.

The specific embodiment

See also Fig. 1, the utility model discloses a kind of cold-keeping bag, it comprises composite bed bag 1.As shown in the figure: composite bed bag ecto-entad successively by vacuum plated aluminum film 101, strengthen PE film 102, compound PE film 103, warm material 104, compound PE film 105, PE film 106 and extrude compound or drench 107 compound compositions of film.

1 mouthful of end of described bag links to connect and carries hand band 3 by carrying hand.See also Fig. 2,3, the described hand button of carrying comprises interior button 21 and outer button 22; Described outer button 22 inside faces have button column 221 respectively and extend to the microscler trough of belt 222 of outer button upper end, also are provided with short button column 223 in this trough of belt 222; Button 21 has the button hole 211 of position corresponding to outer button button column 221 in described.Described short button column 223 length preferably are not more than the degree of depth of microscler trough of belt 222.Describedly fasten 221 and be distributed in regularly around the trough of belt 222, distribute as triangle.The described hand button of carrying can use PE (polyolefin) material or other similar plastic material.

During installation, need to cooperate the bag 1 of offering perforation 11 as shown in Figure 4, described perforation 11 positions are also corresponding to button column 221, and two ends offer respectively corresponding to short button column 223 perforation carry hand band 3, this carries the width of the width of hand band 3 less than trough of belt 222.To carry earlier in the microscler trough of belt 222 that hand band 3 one ends are positioned outer button 22, and select suitable perforation to be located on the short button column 223 according to user's hobby; Then, perforation 11 back of outer button 22 button columns 221 being passed on the bag 1 fastens with button hole 21 on the interior button 21.Similarly, again assembling fixedly the same other end of bag carry hand and bag another side two and carry the hand fixed end, the bag after the assembling is as shown in Figure 5.
