Embodiment Construction

[0043] Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.

[0044] figure 1 It is a schematic top view which shows the example of the cooling bag 10 which concerns on one Embodiment of this invention. figure 1 In the drawing, the inner bag 12 serving as the inner contents of the cooling bag 10 is shown by a dotted line, and the medicine 13 is shown as an example. figure 2 is along figure 1 A diagrammatic cross-sectional view of the arrow II-II of the cooling bag 10, image 3 is along figure 1 Diagrammatic longitudinal section view of arrow III-III of cooling bag 10.

[0045] refer to Figure 1~3 The cooling bag 10 includes an outer bag 11 , an inner bag 12 accommodated in the outer bag 11 , and a medicine 13 accommodated in the outer bag 11 .

[0046]As an example, the outer bag 11 may be a hermetic bag in which two resin sheets 14 and 15 with rounded four corners are stacked in a vertical rectangle in a plan...

Abstract

The present invention provides an improved cooling bag such that the application of a prescribed force or greater from the exterior of an outer bag results in an inner bag within the outer bag being ruptured reliably, causing an endothermic reaction to occur rapidly and infallibly. Also provided is a production method for the cooling bag. This cooling bag comprises an outer bag 11 and an inner bag 12. The outer bag 11 houses a chemical 13 in powder-particle form. The inner bag 12 has a predetermined size, has water or a hydrate sealed therein, and is housed inside the outer bag 11. The cooling bag 10 is such that the application of a predetermined force or greater from the exterior of the outer bag 11 results in the inner bag 12 being ruptured within the outer bag 11, so that the water in the inner bag 12 is released into the interior of the outer bag 11 and soaks the chemical 13, thereby causing an endothermic reaction. In order to prevent movement of the inner bag 12 inside the outer bag 11 when force is applied from the exterior of the outer bag 11, a stopping part capable of preventing movement of the inner bag 12 is provided on the outer bag 11 in the cooling bag 10.

Description

technical field [0001] The present invention relates to cooling bags and methods of making the same. Background technique [0002] Patent Document 1 discloses a conventional example of a supercooling bag. The cooling bag disclosed in Patent Document 1 has the following structure, that is, "the granular raw material of the endothermic agent is formed into a column or a block, and the specific surface area and the dissolution rate with respect to water are reduced thereby. The heat absorbing agent is directly enclosed in a synthetic resin film bag together with a water-absorbing synthetic resin or (and) a granular heat absorbing agent as a raw material, or sealed in a synthetic resin film bag after being stored in an inner bag perforated with small holes .” (Abstract of Patent Document 1). When this conventional cooling bag is used, 60 ml of tap water at 25° C. is poured into the cooling bag through the check valve V. [0003] Patent Document 2 discloses another conventiona...
