<P>PROBLEM TO BE SOLVED: To provide a packaging container 1 of good design with a film formed on the entire outer surface of the container by printing or the like, in which a print film is prevented from being peeled off due to a friction force from a corner part and its vicinity when packaging containers are stacked in a box-making process by a box-making machine. <P>SOLUTION: The packaging container 1 includes base plates 11, 21 and side walls 12-15, 22-25 standing from the periphery of each base plate in an expanding manner such that corner parts are formed by adjacent side walls on peripheral side wall parts formed by the side walls. The films A-D each having a friction coefficient smaller than that of any other area of an article accommodating surface are formed in predetermined areas on both sides of ridges of the corner part and on the article accommodating surface side of the corner part. When the upper packaging container 1 on sinks into the lower packaging container 1 upon stacking, the corner part of the upper packaging container 1 is brought into contact with the films A-D formed on the corner part of the lower packaging container 1. Thus, a friction resistance is reduced, so that the print film in the vicinity of the corner part of the upper packaging container 1 is not peeled off. <P>COPYRIGHT: (C)2012,JPO&INPIT |
