Title:
METHOD FOR PACKAGING ARTICLE
Document Type and Number:
Japanese Patent JP3580401
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To package an article with a pressure raised inside a packaging material by vaporizing a liquid or solid vaporizable substance after the liquid or solid vaporizable substance which vaporizes at normal temperature with normal pressure is inserted inside the packaging material together with the article and the packaging material is sealed.
SOLUTION: Two tennis balls 1 with an internal pressure of 186 kPa for example and dry ice 2 taken out of a cold insulating container are put in a steel can 10 with an upper part opened, and a lid material 3 is put over the upper opening and caulked for hermetically sealing the steel can 10. If this is left under normal temperature with normal pressure, the dry ice 2 vaporizes to allow the inside of the steel can 10 to be kept at a high pressure. This packaging method facilitates operation since a vaporizable substance such as dry ice 2 may be only packaged with an article in a packaging material. In addition, since the vaporizable substance such as the dry ice 2 is relatively inexpensive, packaging can be done at a low cost.
