Double cavity form carrier

The invention relates to a holding ring for a blow mould for locking and fixing a plastics material pre-form, with a support face for supporting a collar of the plastics material pre-form and a receiving cavity extending at a right angle to a main extension plane of the support face for receiving a neck region of the plastics material pre-form, wherein the receiving cavity is widened radially outwards in a conical manner at least locally in the cross-sectional area thereof starting from the support face along a longitudinal direction (L) of the plastics material pre-form.

A plastics material container has an aperture area, a shoulder area adjoining the aperture area in a longitudinal direction of the plastics material container, a main body adjoining this shoulder area in the longitudinal direction of the plastics material container and a base area adjoining the main body in the longitudinal direction of the plastics material container. The shoulder area is widened in the longitudinal direction of the plastics material container from the aperture area in the direction of the main body, and a transition area is provided between the aperture area and the shoulder area. The transition area has a portion widening in the longitudinal direction of the plastics material container from the aperture in the direction of the shoulder area and having a straight course.

An apparatus for shaping plastics material pre-forms into plastics material containers with a blow mold which has at least two blow mold parts which are arranged so as to be movable with respect to each other on first and second blow mold carrier parts. A pressure pad arrangement is arranged between at least one blow mold carrier part and the blow mold part. The pressure pad arrangement is designed in such a way that the force acting between the blow mold carrier part and the blow mold part has a first force component which acts in a first pre-set region in the peripheral direction of the blow mold part and a second force component which acts in a second pre-set region in the peripheral direction of the blow mold part.

A container made from plastic for holding beverages. The container comprises a mouth, a wall section which adjoins the mouth in a longitudinal direction (L) of the container, and a base section which is designed as a standing face. The wall section merges into the base section. The container is formed in one piece. The base section has an injection point located in the interior in a radial direction (R) with respect to the longitudinal direction (L), and a central region which surrounds this injection point, and also a transition section which extends from the central region to the wall section. The transition section has a curvature with a finite radius of curvature in at least one and preferably in every radial direction (R) of the container in every geometric sub-section.

A stretch rod used for forming a preform into a hollow body having in its surface a plurality of raised portions and/or recesses relative to the circular cylinder shape, whereby the stretch rod tip can come into contact with the concave, rotationally symmetric inner surface of the preform at a plurality of locations which are separate from one another. Also, a method and an apparatus for forming a preform into a hollow body, which uses such a stretch rod.
