EASILY SEPARABLE MULTI-LAYERED CONTAINER

摘要

PROBLEM TO BE SOLVED: To provide a structure for easily separating an outer layer container and an inner layer container in an easily separable composite container in which the synthetic resin inner layer container is inserted in and locked to the cardboard outer layer container when the container is disposed. SOLUTION: Coatings of solution-type directive slip-preventive agents 6 and 7 used for stacked corrugated nonslip fiberboard boxes or the like are formed at symmetrical positions on the diameter line of an inner circumferential surface 3 of a cardboard outer layer container 1, and unexpected detachment of an inner layer container inserted in the outer layer container 1 is prevented by the friction resistance of the directional nonslip agents. The outer and inner layer containers can be separated only by applying the drawing force of the magnitude to overwhelm the friction resistance. COPYRIGHT: (C)2004,JPO&NCIPI
