    • A molded plastic bottle (10) has a base (24) having an outside surface rotationally symmetric about a longitudinal axis of the bottle including a convex heel (26) and a central concavity (28) separated by a standing ring (30) supporting the bottle on an underlying surface (S). The convex heel has an upper margin (32) integrally formed with the sidewall (22) of the bottle and a lower margin (34) defining an outer portion (36) of the standing ring (30). The central concavity (28) includes a first surface (40) having a lower most portion (42) defining an inner portion (44) of the standing ring (30). The standing ring inner portion (44) and outer portion (36) intersect in an abrupt edge with the inner portion (44) of the standing ring generally being inclined with respect to the plane (S) at an angle of between about 30° and 50°.
    • 模制塑料瓶(10)具有基部(24),该基部具有围绕瓶的纵向轴线旋转对称的外表面,该外表面包括凸起的跟部(26)和由支撑所述支撑件的立环(30)分开的中心凹部(28) 瓶子在下面的表面(S)上。 凸起的跟部具有与瓶的侧壁(22)整体形成的上边缘(32)和限定立环(30)的外部部分(36)的下边缘(34)。 中心凹部(28)包括具有限定立环(30)的内​​部部分(44)的最下部分(42)的第一表面(40)。 站立环内部部分(44)和外部部分(36)以突出的边缘相交,而立环的内部部分(44)通常相对于平面(S)以大约30°和 50度。
