Embodiment 1

[0024] Propylene glycol is made into a small liquid package with water, and the weight ratio is 85% of water and 15% of propylene glycol. The liquid package is first put into a bag processed with nylon film;

[0025] Put ammonium nitrate into this nylon film bag again, the weight is the equal weight of liquid packet;

[0026] Put superabsorbent resin or sodium polyacrylate (ammonium) into the nylon film bag again, the percentage by weight is 0.5% of the total weight, and then seal the nylon film bag mouth firmly with a high-temperature pressing machine.

[0027] This product can reach the above-mentioned use effect of the present invention. When you need it urgently, just pinch the small package of liquid in the bag, and it will be cooled instantly, it can be as cold as 3 degrees, and the ice pack is like a gel. After the first use, put it in a -18 degree refrigerator to cool down. When you want to use it again, take out the ice pack. The product is like a gel, it will not fr...

Embodiment 2

[0029] Glycerol is made into a small liquid package with water, and the weight ratio is 70% of water and 30% of glycerin. The liquid package made is first put into a bag processed with nylon film;

[0030] Then put urea into this nylon film bag, or the mixture of the two, the weight is the same weight as the liquid packet;

[0031] Put into CMC again in the nylon film bag, percentage by weight is 5% of gross weight, then with high temperature pressing machine the nylon film bag mouth is sealed firmly.

[0032] This product can reach the above-mentioned use effect of the present invention. When you need it urgently, just pinch the small package of liquid in the bag, and it will be cooled down to 5 degrees instantly, and the ice pack is like a gel. After the first use, put it in a -18 degree refrigerator to cool down. When you want to use it again, take out the ice pack. The product is like a gel, it will not freeze, and it feels soft.

Embodiment 3

[0034] Ethylene glycol and water are made into a small liquid package, the weight ratio is 80% water, 20% ethylene glycol, and the liquid package is first put into a bag made of nylon film;

[0035] Then put into this nylon film bag a mixture of ammonium nitrate and urea (half by weight) equal to the weight of the liquid packet;

[0036] Put superabsorbent resin or sodium polyacrylate (ammonium) into the nylon film bag again, the percentage by weight is 1% of the total weight, then seal the mouth of the nylon film bag firmly with a high-temperature pressing machine.

[0037] This product can reach the above-mentioned use effect of the present invention. When you need it urgently, just pinch the small package of liquid in the bag, and it will be cooled down to 5 degrees instantly, and the ice pack is like a gel. After the first use, put it in a -18 degree refrigerator to cool down. When you want to use it again, take out the ice pack. The product is like a gel, it will not fre...

Abstract

The invention relates to an instantaneously-cooling gel ice bag. The preparation steps comprise producing, by weight, 15% to 30% of propylene glycol, glycerol or glycol with 70% to 85% of water together into a small liquid pack, and putting the produced small liquid pack into a bag made of nylon film; putting ammonium nitrate, urea or the mixture of ammonium nitrate and urea of the same weight with the small liquid bag into the nylon film bag; putting, by weight, 0.5% to 5% of the total weight of super absorbent resin or sodium (ammonium) polyacrylate or CMC into the nylon film bag, and sealing the nylon film bag opening firmly through a high-temperature ironing press. The gel ice bag can be used instantaneously without cooling when used for the first time, so that an instantaneous cooling effect is provided, the gel comfort is provided, and the feel and the state are completely different from the previous instantaneously-cooling ice bag during usage; the gel ice bag can be used at any time when required after being cooled in a refrigerator directly after being used for the second time. The ice bag has a cold and heat accumulation effect, feels comfortable during usage and is capable of changing into a gel ice bag from an instantaneous ice bag immediately.

Description

technical field [0001] The medical or household cold compress product of the present invention is particularly an instant cooling gel ice pack. Background technique [0002] In the hot summer, people will inevitably have high fever, itchy skin, sprains and other phenomena in work, study or life. At this time, some products for cold compress are needed. When cold compress treatment is needed, take it out and use it immediately. [0003] In the past, the disposable ice pack only had a quick cooling effect when used for the first time, and it had no effect and no comfort when used later. It had to be discarded, which not only wastes materials, affects the environment, but also increases the cost of use. Contents of the invention [0004] The object of the present invention is to provide an instant cooling gel ice pack, which mainly solves the defects of the above-mentioned prior art. The product of the present invention can be used immediately without cooling for the first t...
