Embodiment 1

[0036] Such as Figure 1 to Figure 2 As shown, a cold storage bag of this embodiment includes a bag body, a cold storage agent is arranged in the bag body, and an adsorption material is also arranged in the bag body, and the cold storage agent can be adsorbed on the adsorption material. The bag body is made of sheet packaging material heat-welded and sealed at the edges.

[0037] In this embodiment, the adsorbent material can be made of paper, cotton cloth, net-like braided fabric and other materials. There are two mechanisms for this kind of adsorbent material to absorb liquid. One is to rely on polar adsorption. The characteristics of lipophilicity, the second is capillary adsorption, there are many gaps in the material caused by its own manufacturing process. The main requirement of the adsorbent material used in this embodiment is that the amount of adsorbed cold storage agent reaches more than three times the weight of the adsorbent material itself.

[0038] In the cold...

Embodiment 2

[0044] The features identical to those of the first embodiment will not be described in detail. The different features of the first embodiment are as follows:

[0045]In the cold storage bag illustrated in this embodiment, the absorbent material is oil-absorbing paper, which is made of wood pulp and polyester, has strong polar adsorption characteristics, and the oil-absorbing paper can absorb oil solution three times its own weight.

[0046] In the cool storage bag exemplified in this embodiment, inorganic hydrate is used as the cool storage agent. Except that the cold storage agent described in the first embodiment adopts organic alkane and ester solution, the cold storage agent can also adopt other forms of liquid, which can realize the refrigeration effect, such as: inorganic water compounds can be used.

[0047] In this embodiment, the adsorbent material is first made to absorb a certain amount of cold storage agent, and then the adsorbent material is spread flat around th...

Embodiment 3

[0049] The features identical to those of the first embodiment will not be described in detail. The different features of the first embodiment and the second embodiment are:

[0050] In the cold storage bag shown in this example, the absorbent material is oil-absorbing cotton, which is made of polypropylene, which is the strongest polar absorbent material available on the market, and can absorb oil solution ten times its own weight.

[0051] The characteristics of the cold storage bag exemplified in the embodiment of the present invention are: firstly, the thickness is controllable, and the volume of the cold storage bag remains unchanged after forming; the adsorption material used in the cold storage bag is not only the carrier of the cold storage agent but also the adsorption body; The affinity of the material itself with the liquid achieves the adsorption of the cold storage agent, and the adsorption can be carried out without adding other materials to the cold storage bag. ...

Abstract

The invention belongs to the technical field of logistics industry, relates to an insulated transport technology, specifically discloses a cold accumulation bag, and mainly solves the technical problems caused by using an ice box during the existing insulated transport. The cold accumulation bag disclosed by the invention comprises a bag body, wherein a cold accumulation agent is filled in the bagbody; an adsorption material is further filled in the bag body; and the cold accumulation agent is adsorbed onto the adsorption material. According to the cold accumulation bag provided by the invention, the manner of absorbing the cold accumulation agent by the adsorption material is adopted, so that the flowability of the cold accumulation agent is changed in the case of no influence on the property of the cold accumulation agent, and the controllable thickness and the adjustable weight of the cold accumulation bag are realized; and meanwhile, the problem of heating non-uniformity at the local positions of the traditional cold accumulation bag and ice box, which are caused due to liquid flowing accumulation in a use process, is solved, and the problem of leakage of the cold accumulationagent in the cold accumulation bag is avoided.

Description

technical field [0001] The invention belongs to the technical field of logistics industry, relates to thermal insulation transportation technology, in particular to a cold storage bag. Background technique [0002] In recent years, with the rapid development of the logistics industry, more and more fresh food and medicines are transported. From production to circulation, fresh food and medicines require full-process cold chain measures. Whether the whole process of cold chain transportation can be realized in logistics transportation has the greatest impact on the quality of fresh food and medicines. The key node is the conversion process of goods from people to cars, people to warehouses and warehouses to cars. [0003] The insulation method currently used in cold chain transportation in the logistics industry is generally passive insulation box transportation. In the application process of the insulated box, it is necessary to use the box body formed by the insulation ma...
