<P>PROBLEM TO BE SOLVED: To provide a shrinkable package which can surely prevent an insect or the like from intruding without giving a misunderstanding to a consumer. <P>SOLUTION: An article 10 to be packaged is surrounded with a heat-shrinkable packaging film 20, and the packaging film is heat-shrunk to bring the film into close contact with the surrounding of the article to be packaged. The article to be packaged is a container with a lid part 12, and a rim part 13 which is a step higher than the central part is formed on the peripheral part of the lid part, and furthermore, a projected part 14 is formed at the center of the rim part, and the surface of the projected part is coated with a heat-sensitive adhesive 30 such as a hot-melt adhesive. At the site of the packaging film facing the projected part, a vent hole 22 for venting air in the packaging film is provided when it is heat-shrunk. Therefore, as the packaging film is brought into close contact with the article to be packaged by deaeration processing, and the packaging film and the article to be packaged around the peripheral part containing the vent hole are stuck and closed with the adhesive, after deaeration processing, there exists no possibility of intruding of the insect from the vent hole. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
