(Industrial Application Field) The present invention relates to a cryogen package, and more particularly to a cryogen package suitable as a cooling body built into a container with a cooling function or the like. (Prior Art) In recent years, containers with a cooling function have been developed that allow beverages such as beer and youth to be cooled and drunk as they are, and various types of cryogens that serve as cooling sources are also known. Among these cryogens, inorganic cryogens such as ammonium nitrate and potassium nitrate have a moderate cooling effect and are relatively easy to handle.
Because it utilizes a cooling effect based on the heat absorption effect of contact with water, the material used to package the cryogen must not only have excellent water permeability and durability, but also heat sealability and economic efficiency. The material design has a huge impact on the overall product quality. However, in order to package such inorganic cryogens, attempts have been made to use relatively economical nonwoven fabrics such as polypropylene nonwoven fabrics, but in this case polypropylene nonwoven fabrics have excellent heat sealability and durability. Because of its hydrophobic nature, it has poor water permeability and slows down the cooling rate.Moreover, when the cryogen is in powder form, there is an inconvenient problem in that the cryogen contained inside leaks out through the nonwoven fabric during the packaging process or the transportation process of the package. It was by no means satisfactory. (Problems to be solved by the invention) The present invention was devised in view of the above circumstances, and its purpose is to have excellent economic efficiency, water permeability, heat sealability, and durability, as well as to An object of the present invention is to provide a refrigerant package with very good cooling efficiency and less leakage of the refrigerant. (Means for solving the problem) In order to achieve the above objective, the inventors of the present invention have conducted extensive research to select a material suitable for packaging inorganic cryogens, and have developed a material that has both heat sealability and water permeability. We have completed the present invention by discovering that the method of packaging the cryogen in special paper is the most economical and has the best cooling efficiency, as well as excellent durability and leakage prevention effects. That is, the present invention relates to a cryogen package characterized in that an inorganic cryogen 1 whose temperature decreases when it comes into contact with water is wrapped in paper 2 made of a mixture of cellulose fibers and synthetic fibers. Hereinafter, the cryogen package of the present invention will be explained in detail based on the illustrated embodiments. FIG. 1 shows an example of a cryogen package of the present invention, in which an inorganic cryogen 1 is wrapped in a mixed paper 2 made of cellulose fibers and synthetic fibers.
It is. FIG. 2 is a cross-sectional view showing an example of how a container with a cooling function using the cryogen packaging body of the present invention is used. The cryogen package 3 stored in the internally partitioned container 5 leaks by pulling the strip 8 whose one end is fixed to the lid 7 of the water container 6 placed above it. The mechanism is such that the temperature drops when it comes into contact with the water. In the present invention, the inorganic cryogen 1 whose temperature decreases when it comes into contact with water is exemplified by ammonium nitrate, sodium nitrate, potassium nitrate, potassium bromide, ammonium chloride, etc., or a mixture thereof, and in addition to these, if necessary. Inorganic, organic,
It is also possible to use a cooling aid made of powder or granular material such as a metal, to which a cooling agent or the like is appropriately added. The cryogen package of the present invention uses paper to package such an inorganic cryogen. Since it must have sufficient water permeability and durability to allow rapid penetration, it must be a mixture of cellulose fibers and synthetic fibers. That is, the mixed paper 2 used in the present invention has high water permeability and cryogen leakage prevention effect based on the excellent hydrophilicity and entangling properties of cellulose fibers, and the durability, paper strength enhancement, and heat sealability of synthetic fibers. Together, these effects make it ideal as a packaging sheet for the inorganic cryogen. The cellulose fibers constituting such mixed paper refer to those obtained by beating one or more types of pulp raw materials such as Ezo pine, Sakhalin fir, Japanese red pine, beech, birch, oak, Kozo, Mitsumata, Manila hemp, etc. On the other hand, synthetic fibers include polyolefins such as polyethylene, polypropylene, ethylene-vinyl acetate copolymer resin,
and at least one type of spinning filament selected from polystyrene, polyvinyl chloride, nylon, polyester, acrylic, vinylon, etc., and the mixed paper of the present invention uses these cellulose fibers and synthetic filaments. In addition to fibers, inorganic fibers such as glass fibers and rock wool fibers, or chemical fibers such as rayon and acetate, etc. may be added as appropriate. Processing such as burning,
Alternatively, in order to further improve water permeability, it may be subjected to hydrophilic treatment by coating with a surfactant or the like. In the mixed paper of the present invention, the ratio of cellulose fibers to synthetic fibers varies somewhat depending on the type of fibers used, but usually 20 to 80 parts by weight of cellulose fibers to 80 to 20 parts by weight of synthetic fibers. In terms of water permeability, heat sealability, durability, etc., it is preferable that the mixed paper has a basis weight of 20 to
A material with a weight of 80 g/m 2 is preferable in terms of economy, prevention of coolant leakage, and durability. (Example) In order to make it easier to understand the excellent effects of the cryogen package of the present invention, Examples will be specifically described. Examples 1 to 3, Comparative Examples 1 to 2 Paper weights made by changing the mixing ratio of cellulose fibers and polyethylene fibers obtained by beating wood pulp with about 30 g of powdered cryogen containing ammonium nitrate as the main component. A cryogen package was prepared using 50 g/m 2 paper and sealed on all sides so that the bag had a square size of approximately 70 mm on each side. Heat seal strength of these cryogen packages,
Table 1 shows the results of measuring water permeability, presence or absence of cryogen leakage, cooling start time, etc. From the same table, the cryogen package of the present invention, in which cryogen is packaged with paper made of a mixture of cellulose fibers and polyethylene fibers, has good sealing strength and excellent durability, as well as a fast cooling rate after water injection, and leakage of cryogen. A number of excellent features were confirmed, including low
