Title: Air permeating means to be used for package, package, and packaging method
Inventor: SUHARA NAOKI
IPC: B65D75/52
Filed: 2000-03-21
Abstract: PROBLEM TO BE SOLVED: To prevent the deformation of a package in the heating of contents even in the case where the contents in the package is sufficiently warmed. SOLUTION: A slide 14 of an air permeating device 10 is moved toward the side of a wrap 76 under pressure when the wrap 76 is expanded, and a protrusion 15 of the slide 14 opens a hole 78 in the wrap 76. Since the wrap 76 is so formed that the hole 78 is automatically opened therethrough due to the pressure difference between the inside and the outside of the wrap 76 during the heating of contents in a package, the wrap 76 is not shrunk more than necessity, and the package can be prevented from being deformed. Accordingly, since the crushing and deformation of a container, which have often occurred in the past, are not caused by the shrinkage of the wrap 76, juice of daily dishes or the like is not spilt out of the container, and an outer face or the like of the container can be prevented from being soiled.
