Fresh keeping ice bag

Abstract

A fresh keeping ice bag comprises an outer plastic bag, an inner plastic bag and a coolant in a packaging bag; the ammonium nitrite and crystallized sodium carbonate are contained in the plastic bag and are separated by an easy-to-detach partition device outside the bag. During use, the partition device is detached, and the temperature can be reduced to about 0 DEG C within 1 minute after the two substances in the bag are fully mixed. The ice bag is convenient to cool, fast in speed, convenient to use and portable. The fresh keeping ice bag is characterized in that the packaging bag is provided with a hopper-like water injection port capable of injecting a solution into the packaging bag. The fresh keeping ice bag is convenient to use and preserve, is portable, non-toxic, tasteless and odourless, does not pollute a fresh keeping object and can be easily separated from the fresh keeping object, and the fresh keeping capacity of the coolant is high and is more than two times that of the coolant of the existing fresh keeping ice bag.

Description

technical field [0001] The invention relates to a fresh-keeping ice bag. Background technique [0002] The current fresh-keeping ice packs all use a combination solution as a cold storage agent, sealed and packaged in plastic soft and hard packaging bags, some of which are slightly toxic, and the cold storage solution is packaged by the manufacturer. The size of each bag is generally 500 grams or 1000 grams. , 2000 grams, etc., so there is an ice pack with a large volume and a heavy weight, and it is afraid that the solution will pollute the fresh-keeping items after extrusion, puncturing and breaking, resulting in high requirements for transportation and storage conditions, large occupation of space, high cost, and impractical. Contents of the invention [0003] Aiming at the deficiencies of the above-mentioned existing technologies, the present invention provides a new type of food that is convenient for transportation and storage, takes up a small amount of special fund...
