BULK CARGO-CONVEYING AND-STORING PACKAGE

摘要

PURPOSE: To increase the strength of a package to eliminate such a danger that the package is broken during transportation, storage, or lifting by reducing a tension generated in the inside package in the resultant force lest the connection point of the inside frame and the outside frame in the inside package substantially receives a stress. CONSTITUTION: This package 10 is constituted of an outside package 11 and an inside package 12 formed in the outside package. And the inside package 12 is constituted of an outside frame 13 and an upper frame 14 which are mutually connected at a part thereof. The inner pressure P1 in the package 10 works as a tension F2 acting to the outside package 11. The tension F2 generates a resultant force F3 acting through the corners of the outside package 11. The resultant F3 lessens a stress existing in the inside package 12 so that a stress is substantially eliminated in the connection point 19. That is, a stress is shifted in the package 10 so that any stress does not exist in the connection point 19 in the inside package 12.
