Filling type cold storage package

Abstract

The invention discloses filling type cold storage package. The filling type cold storage package comprises a first outer film and a second outer film, wherein the first outer film and the second outer film, by virtue of hot-press welding, are formed into a plurality of liquid storage chambers which are separated from one another; a liquid inlet is formed in each liquid storage chamber, and each liquid inlet communicates with each liquid storage chamber through each liquid inlet channel; each liquid storage chamber also comprises a plurality of liquid storage units, and the liquid storage units of the same liquid storage chamber communicate with one another through a liquid guide channel formed by hot-pressing. The first outer film and the second outer film of a cold storage package material are flexible plastic films, so that good deformability is achieved; in use, the filling type cold storage package can be bent, and can be fitted with the surface of an object enclosed by the filling type cold storage package while a cold storage agent is charged for use, so that cold transmission uniformity is improved, and the temperature at each part of the packaged object is kept consistent. Each liquid storage chamber is also divided into the plurality of liquid storage units, so that the cold storage agent can be uniformly distributed in the liquid storage chambers under external force, a condition that the cold storage agent at certain position is missing is not liable to occur, and the cold keeping effect is guaranteed.

Description

technical field [0001] The invention relates to the technical field of cold chain logistics, in particular to a filling cold storage package. Background technique [0002] Coolant is usually a viscous jelly mixture composed of organic or (and) inorganic compounds, which can absorb and store a large amount of cold energy at low temperatures, and release a large amount of cold energy at higher temperatures, which can be stored for a longer period of time. Maintain a low temperature environment in and around a small area. [0003] The main problem in the field of cold chain transportation such as food, medicine and vaccines is the broken chain of the cold chain link. Food and medicine are pre-cooled at the place of origin and loaded into the transport vehicle to reach the wholesale market at the place of sale, and finally enter the retail link for storage. Both are prone to cold chain breaks. The use of cooling agents can effectively solve the problems encountered in the pre-...

AI Technical Summary

Problems solved by technology

[0004] The cold storage agent is usually packaged in the cold storage plate for use. The cold storage plate in the prior art is designed as a rectangular parallelepiped plate structure. According to the specific use, the cold storage plate is processed into various volumes, but the existing The cold storage plate in the technology is generally thick, which makes it inconvenient to use

When used in conjunction with the transport box, the traditional cold storage plate can only be placed on the surface and surroundings of the transported object, resulting in uneven transmission of cold energy in the box. When the placement is irregular, the above disadvantages are more obvious

In addition, traditional cold storage plates are only suitable for transportation in cold chain logistics and cannot be used in daily life, that is, ordinary consumers cannot touch and use them.
