First cooling bag

Abstract

This product is a neck cooling bag for cooling a person's neck by wrapping or draping it around the neck with a cooled cooling pack inside. The product is formed in a strip shape, with pockets for storing cooling packs at the center and both ends. Openings are provided on the back side of the product, allowing the cooling pack to be inserted into each pocket through these openings. The cooling performance and feel can be improved by using a pile fabric for the surface of the product. The central pocket of the product has the back side facing the skin, and it is used by wrapping or draping it around the neck so that this side is in contact with the surface of the neck. The cooling performance can be further improved by placing an insulating material on the non-skin contact side inside the central pocket (see the reference diagrams for the HH section KK end face with a cooling pack inside and the II section KK end face with a cooling pack inside). As an example of the cooling pack, a sealed cooling pack bag made of soft synthetic resin film filled with a gel-like cooling pack consisting of a mixture of water, a water-absorbing gelling agent, and a freezing point depressant is used. To use this item, place the cooling pack in at least the central part of the bag and wrap it around your neck (see the reference diagrams showing the state of use). This item is formed lengthwise so that when wrapped around the neck, both ends hang down in front of the chest. These ends may be tied together (see Reference Diagram 5 showing the state of use), or bundled together with a string, rubber band, band, or other fastener (see Reference Diagram 6 showing the state of use). These ends may also be inserted into clothing (see Reference Diagrams 1 and 2 showing the state of use), or left outside of clothing (see Reference Diagrams 3 and 4 showing the state of use). If cooling packs are also placed in the bag parts at the ends, other areas besides the neck can be cooled as needed by bringing these ends into contact with the skin.
