Abstract
A body portion (120A) that is a cylindrical body has one end portion, such as a lower end portion or the body portion (120A) or a first part (126) of a body portion (120), that is folded back inwardly. The body portion (120A) has at least one planar-shaped flat section, such as a second flat section (122) or a fourth flat section (124). A notch, such as a notch (K1) or a notch (K2), is provided at one end, such as a lower end, of the flat section. The one end portion includes a portion provided with the notch, such as by providing the notch (K1) or (K2) at a lower end of the lower end portion of the body portion (120A) or at a distal end of the first part (126A) of the body portion (120).
Claims5
A three-dimensional body having one end portion that is folded back inwardly, comprising:
- four planar-shaped flat sections;
- and
- two notches arranged only at two ends of two flat sections of the four flat sections, wherein
- the three-dimensional body has a horizontal cross section, wherein the cross section forms a rectangular-shape;
- having four curved corners;
- and having two short sides and two long sides,
- the four flat sections form the two short sides and the two long sides of the rectangular-shape,
- the two flat sections having the two notches form the two short sides of the rectangular-shape of the horizontal cross section,
- the two notches are arranged in the bottom end portion of the three-dimensional body, and
- wherein the two notches are for preventing occurrence of buckling when folding back the one end portion inwardly.
