    摘要: Apparatus (1) for forming plastic preforms (10) into plastic containers (20), having at least one blow mould (14) which has at least two blow mould side parts (14a, 14b) and a bottom mould (14c), wherein the blow mould side parts (14a, 14b) and the bottom mould (14c) forming a cavity which corresponds to a negative contour of the plastic container (20) to be formed, wherein between the blow mould side parts (14a, 14b) and the bottom mould (14c) at least a first parting plane (22) and a second parting plane (24) is present, wherein the first parting plane (22) extending between the two side parts (14a, 14b) and the second parting plane (24) extending between the side parts (14a, 14b) and the bottom mould (14c), wherein the blow mould side parts (14a, 14b) and the bottom mould (14c) can be separated from each other by the second parting plane (24) and the bottom mould (14c) can be removed from the blow mould side parts (14a, 14b) by a bottom lift. According to the invention, at least a part of the bottom contour (15b) of the bottom mould (14c) is arranged in the blow mould side parts (14a, 14b).

    摘要: A plastic container has a mouth portion, a main body, and a base portion which adjoins the main body. The base portion has a central region as well as a diaphragm which runs in a circumferential direction and extends from the central region to the main body. The central region is pivotable relative to the main body between at least two positions which differ with regard to an internal volume of the container. The wall has at least one and preferably at least two circumferential grooves and are spaced apart from one another. The central region has a projection extending in the direction of the interior of the plastic container, and at least one web extending at least in part in a radial direction in the circumferential wall.

    摘要: A blow mold includes: a pair of movable molds for forming engagement grooves of a container body; and advancing/retreating mechanism units for advancing and retreating the movable molds between a standby position and a molding position. The advancing/retreating mechanism units are equipped with drive shafts to which the movable molds are fixed and which are rotatably supported with respect to a cavity mold; actuator devices which each have a linear-motion shaft capable of advancing and retreating in a direction orthogonal to the drive shaft and which are each swingably provided with respect to the cavity mold; and link members each having an end side fixed to the drive shaft outside the cavity mold and an opposite end side coupled to the linear-motion shaft.

    摘要: A container including an opening defined by a finish portion, and a base at an end of the container opposite to the opening. The base includes a standing ring extending inward from a heal to a center pushup portion. The center pushup portion includes an pushup ring surrounding an inversion portion. In an as-blown position the inversion portion extends outward and beyond the pushup ring such that the inversion portion is further from the opening than the pushup ring. In a final position the inversion portion is inverted relative to the as-blown position such that the inversion portion extends inward so as to be closer to the opening than the pushup ring. The inversion portion is mechanically moved from the as-blown position to the filled position with an inversion device after the container has been filled to reduce vacuum or increase pressure within the container.
