Filling type cold storage bag

Abstract

The invention discloses a filling type cold storage bag. The filling type cold storage bag comprises a bag body filled with a cold storage agent, the bag body forms a cylindrical helix, a bag bottom and an opening are formed at the tail ends of the bag body respectively, the bag bottom is sealed, the bag opening is packaged in a hot-pressing mode, the widest parts on the two sides of the bag body are connected though a tightening ring, and the bag body is provided with chaining bars in the tightening ring direction. The bag body of the filling type cold storage bag is designed into the helix, and the bag body can form a disc when not in use, so that occupied space is reduced, and centralized transportation is convenient; the bag body can be wound around a bottle in a sleeving connection mode from top to bottom when in use, so that the cold storage effect is enhanced; due to buffering of the filling type cold storage bag in the transportation process of bottle-shaped articles, a buffering protection effect can be achieved; as the bag body forms a gap around the bottle, different bag bodies can be placed in a staggered mode when stacked, and space is saved; a top cover and the tightening ring are fixed to the top and the bottom of the bottle respectively, and the fixing firmness of the bag body can be improved by adopting the chaining bars for chaining of the bag body.

Description

Technical field [0001] The invention belongs to the technical field of cold chain logistics, and specifically relates to a filling type cold storage bag. Background technique [0002] The cold storage agent is usually a viscous gel mixture composed of organic or inorganic compounds, which can absorb and store a large amount of cold energy at low temperatures, and can release a large amount of cold energy at higher temperatures, and can maintain itself and Low temperature environment in a small area around. [0003] The main problem in the field of cold chain transportation such as food, medicine and vaccine is the disconnection of the cold chain link. Food and medicine are pre-cooled and loaded into the transport truck at the place of production to reach the wholesale market at the place of sale and finally enter the retail link for storage. The cold chain is prone to scission in both cities. The use of cold storage agents can effectively solve the problems encountered from the p...

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. If there are more varieties of items to be transported during the cold chain transportation, especially bottled items, 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.

At the end of the cold chain logistics, consumers are still unable to smoothly transfer items that need to be kept in a refrigerated state. When transferring items, they still need to use inconvenient refrigerators, cold storage boxes, etc. for packaging
