Document Type and Number:
WIPO Patent Application WO/2016/117168
Kind Code:

Abstract:
The present invention discloses a container body (2), as a cup-shaped member the volume of which can be varied and which can be collapsed to a flat shape. This container body (2) has a barrel part (20), and a bottom part (10) that continues from the barrel part. The rim of the opening of the barrel part (20) and the rim of the bottom part (10) are polygonal in shape. Square-shaped planar parts (27x, 28x) are formed between mountain-fold lines (21a, 21b) of the rim of the bottom part (10) and valley-fold lines (24a, 24b) of the barrel part (20), and square-shaped planar parts (27y, 28y) are formed between the valley-fold lines (24a, 24b) and the circumference of the rim of the opening. Corners of the rim of the opening and corners of the rim of the bottom part (10) are linked by mountain-fold lines (22x, 22y), the intersection (P1) of which deviates in the circumferential direction. A triangular planar part (29x) is formed by mountain-fold lines (22x, 25) and a valley-fold line (26x), and a triangular planar part (29y) is formed by the valley-fold lines (22y, 25) and a valley-fold line (26y).
