<p>PURPOSE:To reduce transportation cost by a method wherein, after use of an inner bag structural body capable of containing a large amount of contents, a portion deformed by use is removed from other portions and a new inner bag structural body replaceable with the deformed portion is combined with the other remaining portions to be reused. CONSTITUTION:A substantially rectangular parallelopiped-shaped inner bag structural body 2 of a synthetic resin is made, and an insert port 4 for contents is formed at an upper part on one side of the inner bag structural body 2 of a synthetic resin. The manufacture of the inner bag structural body capable of containing a large amount of contents is such that, after use of the inner bag structural body 2, a portion deformed by use is removed from other portions and a new inner bag structural body 2 replaceable with the deformed portion is combined with other remaining portions and that the deformed one is recycled to a reusable inner bag structural body so as to be reutilized. The reuse of a portion which is likely to cause an unexpected accident is reliably prevented and, as a matter of fact, the manufacture for supplying a usable product under the same reliability as that of an inner bag structural body which is all newly manufactured to be used is made possible, and this inner bag structural body is effective in business of transportation by a ship.</p> |
