Abstract

The utility model relates to an ice bag, which comprises bag body. The inner part of the bag body forms space to hold objects, and the bag body is fixed with a connecting band outside. The opening combination point of the bag body is sealed and opened via a zipper. The bag body is made of soft material compound and is divided into three layers from outside to inside in turn, which are an outer coating layer, a middle heat insulation layer and a cleaning waterproof liner layer. The inner space of the bag body is provided with a cold source body. The ice bag is suitable for preserving the heat in the transportation process after the frozen food is bought, and is suitable for placing the frozen food and the beverage in summer outgoing. The utility model has the advantages of good heat preservation effect, convenient carrying and convenient use.

Description

Ice bag

Portable knapsack or carry bag when this utility model relates to a kind of going out is meant a kind of ice bag with cold insulation insulation effect especially.

In the past, during the broiling summer, after people have bought frozen food, beverage, owing to there is not a cool-bag, was less than toward contact and reaches destination and just begin to have melted.Also have, when people travel outdoors, usually can feel thirsty, hope can drink one glass of ice-cold good to eat beverage lowers the temperature, and beverage of carrying or mineral water be because cool inadequately, and panesthesia drinks unfulfilling.Sold analog such as heat-preserving container, couveuse or incubation chamber on the market, this series products generally adopts the vacuum plating silver inner bag to reach heat insulation effect, therefore has some defective inevitably, and the one, volume is less, can only hold a spot of article; The 2nd, easy breakage, inconvenience hold the harder objuct product, and need when carrying meticulous; The 3rd, carry on the arm by the profile inconvenience back of the body that hard rigid material constitutes, carry limited.

The purpose of this utility model is to provide a kind of ice bag with cold insulation insulation, makes it keep the intravital temperature of bag in long period of time relatively, and carry and use all very convenient, to remedy the defective that existing various bags, bag exist.

The purpose of this utility model is achieved through the following technical solutions.

A kind of ice bag includes bag, forms a space that holds object in the bag, is fixed with connecting band in the bag outside, and sealing effectiveness slide fastener involution and unlatching preferably adopted in the opening junction of bag.Described bag is composited by flexible material.By outside to inside being divided into three layers successively, i.e. external coating, middle insulation layer and cleaning water-resistant liner layer.Its external coating is made by softish waterproof fabric, and middle insulation layer is made by flexible, porous material, and cleaning water-resistant liner layer can be made by reflectorized materials such as aluminium foil or light waterproof cloth, plastics, artificial leather classes.Above-mentioned three layers closely are attached to together, make the different shape bag according to the design of different shaping again.In the inner space of bag, this utility model also is provided with the low-temperature receiver body, and this low-temperature receiver body is made (genus prior art) by cold insulation material, be poly-colloid at normal temperatures, have resistance to low temperature preferably, in the time of-30 ℃, still can keep its rerum natura in good condition, can be recycled.Should also have higher low temperature specific heat capacity simultaneously by poly-colloid, as more than 0 ℃, its specific heat capacity is 2 times of water, and in the time of-5 ℃-0 ℃, its specific heat capacity is 15 times of ice, and this shows that this poly-colloid is to replace the ideal product of ice as low-temperature receiver.The low-temperature receiver body is sealed in the plastic bag, can be fixed on ice bag inside bottom surface, sidewall, or arbitrarily be placed in the gap of article in the bag.

Compared with the prior art, the utlity model has following tangible advantage:

1, bag is composited by trilaminate material, middle insulation layer adopts porous material to make, liner is made by reflectorized material, this structure makes heat passage three kinds of mode-radiation, conduction and convection current all be blocked, it is interior temperature-resistant to keep bag for a long time, so ice bag has good effect of heat insulation.

2, the setting of low-temperature receiver body in this utility model can be played refrigeration, makes that the temperature in the ice bag rises slowlyer, and heat insulation effect is obvious further.Through overtesting, with the canned drink of putting into 12 ℃ in the ice bag, put into two bags of low-temperature receiver bodies that take out from freezer compartment of refrigerator again, under the environment of 40 ℃ of ambient temperatures, after 4 hours, the test beverage temperature is 14 ℃.

3, the making of low-temperature receiver body is simple, very easy to use, can arbitrarily be placed in any position in the bag, but and repeated multiple times use.

4, the bag of ice bag is made by flexible material is compound, and is lightly attractive in appearance, is convenient to carry on the arm or portable, durable, not fragile with carrying on the body.

5, the ectonexine of bag is waterproof material, can be effectively rainproof and prevent that the article of depositing in the bag from spilling leakage, infiltrate the not middle porous layer of easy cleaning.

6, this ice bag scope of application is extensive, holds frozen food and beverage when being suitable for purchasing after the frozen food insulation in transportation and going out outing summer, has higher utility.

Below in conjunction with embodiment and accompanying drawing, the construction features of this utility model ice bag and the effect that is reached are described further.

Seeing also Fig. 1 and Fig. 2, is a kind of ice bag shown in the figure, and this ice bag includes bag and is fixed on the connecting band in the bag outside, and the opening junction of bag is sewed with slide fastener.Bag is composited by trilaminate material, and its external coating 1 can be selected linings such as cotton, canvas, synthetic fibers, nylon, artificial leather, and the surface is through water-proofing treatment; Intermediary insulation layer 2 can adopt PE Foam porous materials such as (polyethylene foameds), and thickness can be 1-10mm; Cleaning water-resistant liner layer 3 is made by aluminium foil or the light preferably cloth of reflecting effect.In the ice bag, be provided with low-temperature receiver body 4, the poly-colloid that this low-temperature receiver body 4 is made by cold insulation material more in addition plastic packaging form.This low-temperature receiver body can be arranged on the bag inside bottom surface, also can be fixed on sidewall, and the method for more convenient practicality is that the activity of low-temperature receiver body is placed in the ice bag in the middle of the article, makes a bag interior temperature be tending towards balanced more like this.Structure promptly can be kept the intravital temperature of bag in longer relatively following period of time thus.

This utility model ice bag needs earlier the low-temperature receiver body to be put into freezer compartment of refrigerator freezing 24 hours before use, places it in after the taking-up in the middle of the food and drink in the ice bag, and the involution slide fastener can be carried.
