| 摘要 |
The present invention provides a bottomed cylindrical container, comprising a body wall (2), a bottom wall (3), and a ring-shaped foot (4) downwardly extending from the bottom wall, said container being produced by thermo-molding a resin sheet, characterized in that said foot (4) is formed by folding an inner wall (7b) by compressed fluid to be fusion-bonded with an outer wall (7a), so as to form the foot (4) comprising the inner wall (7b) and the outer wall (7a). The present invention also provides a bottomed cylindrical container, comprising a body wall (31) having a grounding edge (33) at a lower end thereof, and a bottom wall (32), said container being produced by thermo-molding a resin sheet, characterized in that said bottom wall (32) connects with an upper edge (35) of an inner wall (34) produced by folding back the body wall (31) along the grounding edge (33) and by fusion-bonding it to an inner periphery of the body wall (31). In addition, the present invention provides the methods for thermo-molding these containers and their apparatuses. <IMAGE> |
