<p>A tube-like plastic container (1) and a preform (11) therefor, the tube-like plastic container (1) comprising a bottomed drum part (3) molded by stretch-blowing in thin wall thickness continuously connected to a mouth part (2), wherein a continued portion between the drum part (3) and the mouth part (2) is formed in a shoulder part (5), and the drum part is formed in a tapered flat wedge-like form in shape together with a bottom end (4); the preform (11) therefore, comprising a bottomed drum part (13) integrally formed with and continuously connecting to the mouth part (12), wherein a continued portion between the drum part (13) and the mouth part (12) is formed in an projecting edge (15) in a concentric circle in cross section and the drum part (13) is formed in a flat wedge-like form in an elliptic or oval shape in cross section, a peripheral wall of the drum part being formed thicker in thickness than the wall of the mouth part (12), the bottom end (14) being formed into a thinner flat bottom in wall thickness than the drum part (13), the drum part (13) being tapered toward the bottom end (14) on a slant, and the bottom end (14) is formed in a flat bottom thinner in wall thickness than the drum part, whereby even the resin tube-like container molded by stretch-blowing can be used as a bottomed one without requiring a secondary working as in the case of a packaging container in an usual shape. <IMAGE></p> |
