摘要：
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.
摘要（中）：
一种管状塑料容器（1）及其预成型件（11），该管状塑料容器（1）包括通过与口部连续地连接的薄壁拉伸吹塑成型的有底鼓部（3） 2），其中在鼓部分（3）和口部分（2）之间的连续部分形成在肩部（5）中，并且鼓部分形成为锥形的平的楔形形状以及 底端（4）; 因此，预成型件（11）包括与口部（12）一体形成并连续地连接的有底鼓部（13），其中，在鼓部（13）和口部（12）之间的连续部分形成为 横截面为同心圆的突出边缘（15）和滚筒部分（13）以椭圆形或椭圆形的横截面形成为平坦的楔形形状，鼓部分的周壁形成为较厚的 厚度大于口部部分（12）的壁，底端（14）形成为比鼓部分（13）更薄的壁厚的平坦底部，鼓部分（13）朝向底端（14）逐渐变细 ），并且底端（14）形成为比鼓部更薄的平坦的底部，由此即使通过拉伸吹塑成型的树脂管状容器也可以用作底部的容器，而不需要 如在通常形状的包装容器的情况下二次加工。
