CONTAINER STRUCTURE DESIGNED TO BE MANUALLY COLLAPSIBLE AND MARKING GAUGE FOR MANUAL COLLAPSIBLE OPERATION

摘要

PROBLEM TO BE SOLVED: To provide a container structure designed to be manually collapsible and a marking gauge for manual collapsible operation in which its collapsible operation can be easily carried out by applying a small external force and the container can be disposed of in its compacted state. SOLUTION: There is provided a container structure (for example, a can 1A) containing as its composing element a circumferential wall 2 defining a circular cross section. In order to make a design of manual collapsible container structure, there is provided a clashing generating element 5 in which the container structure 1A is axially pressed with a force against the circumferential wall of it while a rotational force is being applied around its axial line. Further, in the case of the container structure including as composing elements a side wall having regular polygonal section as seen in its cross sectional view, there is provided the clashing generating element 5 extending along an orthogonal line inclined toward the same direction in respect to each of the side walls of the structure so as to design it to be easily collapsed by a manual operation.
