Insulation bag with cooling effect

The invention relates to a heat preservation bag with a cooling effect, in particular to a cold storage bag (or box) which can carry and keep fresh.

Refrigerated insulated bags (or boxes) that are usually carried out or traveled today, usually used as fresh food or beverages, such as portable refrigerated duffel bags or fishing refrigerated refrigerators, the wall of the bag (or box) It contains insulating cotton or styrofoam material, so it has an insulating effect. Because there is no ice in the bag (box), the cold preservation is limited, so it can not achieve the effect of long-term preservation. Although a user puts a crushed ice cube or a chemical ice pack in a bag (box), it can only be placed on the bottom surface of the bag (box) and cannot be placed on the periphery of the bag, so the bottom of the bag (box) is cold. But there is no coldness around, so the preservation effect is still very limited.

Furthermore, the above-mentioned heat preservation bag does not have a waterproof structure, so that the ice cubes placed in the bag are melted, and the generated water will leak into the slits and leak out, especially the heat preservation bag, because the bag body is a soft aluminum foil piece. Made of stitching, the waterproof effect is less than ideal.

In view of this, how to improve the traditional shortcomings and provide an external portable thermal insulation bag that can keep cold for a long time, keep fresh, and does not need chemical cold liquid, and does not leak water, has become a subject to be improved by the present invention.
