Description

[Detailed explanation of the idea] The present invention relates to ice packs.

Ice packs are commonly known as ice bags used to cool affected areas. Conventionally, there was no similar ice pack other than one made of rubber. (a) Rubber ice packs emit a characteristic odor of rubber (latex), so they can be used to treat the head of a patient with a fever. If used against the skin, it will cause discomfort to the patient.

(b) Even if the quality deteriorates, the adhesive is easily damaged, so it must be replaced frequently, which is uneconomical.

(c) After using a rubber ice bag, it is necessary to dehydrate and dry it and apply a powder such as celestial pollen or American flour to prevent the rubber from sticking before storing it. Even if they are treated and stored without being compressed, rubber ice packs cannot be stored forever, and because they are made from natural resin, they often deteriorate, weaken, or stick due to oxidation and cannot be reused. It has become impossible.

(d) Production costs increase.

There are some drawbacks, such as:

The ice bag of the present invention was created in view of the above circumstances, and is made by folding a nonwoven fabric coated with synthetic resin on one side in half with the synthetic resin coating on the inside, and removing the folded part. This bag is characterized by having a bag formed by welding a synthetic resin coating on the bottom and both sides, and a string for tying the opening of the bag.

Embodiments of the present invention will be described below with reference to the drawings.

As an example is shown in Figures 1 to 3, the ice bag of the present invention has one side coated with a thin layer (preferably 30 to 40 microns) of synthetic resin such as vinyl or polyethylene (the coated side is represented by 2). ), and the nonwoven fabric 1 cut to the required size is folded in half with the coating surface 2 facing inside, and the synthetic resin coating is melted by applying hot press processing or the like to both sides with the folded part 3 as the bottom. A bag 4 made of adhesive and adhesive, and the bag 4
It is made up of a string 6 that ties up the opening 5 of the holder.

When using an ice pack with such a configuration, fill ice or cold water into the bag 4 through the opening 5, make the opening 5 into a purse string, wrap the string 6 lightly around the outside of the upper part of the bag 4, and then close the bag. Excess air in the opening 5 is appropriately extracted from the opening 5, and then the opening 5 is closed by strongly pulling both ends of the string 6. In order to prevent moisture from leaking out, a hanging ring 7 is made using the end of the wrapped string 6, and the hanging ring 7 is suspended using a necessary means and brought into contact with the affected area. use. When the ice in the bag 4 melts and the cooling effect decreases, add ice again as appropriate. Although an example in which ice is used as the cooling medium has been shown above, since this nonwoven fabric bag is odorless, it is also possible to cool or freeze the water in the bag by hanging it in a refrigerator. Furthermore, in any of the above cases, due to the waterproof effect of the synthetic resin applied to the nonwoven fabric 1, there is no problem of water leakage during use.

According to the ice bag of the present invention, (i) the non-woven fabric used as the material of the bag and the synthetic resin coated on the non-woven fabric are unalterable, so they can be stored forever and even after use; If you do not dehydrate and dry it like a sea urchin and apply powder such as heavenly pollen to the inside and store it without pressing it, it will not stick and cannot be reused, and there is no need for troublesome storage steps and it can be stored forever. can withstand.

(ii) Since nonwoven fabrics and synthetic resins are odorless, they do not cause discomfort to the patient due to odor even if they are applied to the head of a feverish patient.

(iii) Non-woven fabrics and synthetic resins are odorless and therefore do not transfer odors to other foods even when placed in the refrigerator, so the hassle of preparing ice can be saved.

(iv) It is also possible to prepare multiple bags and cool them alternately in the refrigerator.In this way, it is effective as an emergency measure for fevers of unknown cause in infants that often occur late at night, and can be used regularly at home. It is useful as a.

(v) The surface of the non-woven fabric feels good against the skin, like a blanket, and even if it is applied directly to the affected area without the need for a patch, water droplets will not accumulate, making it comfortable to use.

(vi) It is economical because it can be produced at a lower price than rubber products and can withstand repeated use if handled with care.

It can produce excellent effects such as
