Abstract: The invention relates to a container made of plastics material, provided with a body and with a bottom in the continuation of the body at a lower end of the body. The bottom has an oblong curved contour and comprises a seating surface forming a standing plane of the container. The standing plane has an oblong closed curved shape extending along a longitudinal median axis and a transverse median axis. The standing plane also has an arch extending from the seating surface as far as a central zone of the bottom, the arch delimiting a concavity oriented toward the outside of the container.

Abstract: Provided is a stretching rod for a molding unit for manufacturing a container from a preform and a method for manufacturing a container by stretch blow-molding. The stretching rod extends longitudinally, parallel to a main axis Y, and comprises a body of cylindrical or tubular form, a distal end in the extension of said body, at least one internal channel to allow the circulation of a cooling gas to said distal end, a flat situated at the distal end of the stretching rod, an end-fitting protruding from said flat and a plurality of orifices, said orifices being fluidically connected with said internal channel and being distributed around said end-fitting on said flat. The rod can include an annular skirt in the extension of said body, at said distal end, said skirt having a height less than the height of said end-fitting.

Abstract: The invention relates to a container made of plastic material comprising a petaloid bottom having an axis of symmetry and comprising a central dome that projects toward the interior of the container; a series of feet projecting toward the exterior of the container that radiate from the central dome and each of which has a crest path that extends from an external edge of the dome to a peak radially remote from the dome; and a series of valleys each formed as a hollow between successive feet. Each crest path has an internal section extending from the external edge of the dome to a junction at a distance R2 from the central axis. Each crest path also has an external section extending from the junction tangentially in line with the internal section to the peak. The distances R1 and R2 are in a ratio where 45%≤R1/R2≤60%.

Abstract: Disclosed is a container provided with a petaloid base having feet that form protrusions towards the outside of the container, separated two by two by recessed valleys that extend radially from a central dome of the base to a periphery of same, each foot having a median face with concavity facing outwards and extending via an end face forming a discontinuous seat ring, with a planar cross section, each valley having an inner portion extending from the central dome and an outer portion that meets the periphery, the inner portion and the outer portion being, in cross section in a central radial plane at the valley, straight and together forming an obtuse angle protruding towards the outside of the container and meeting at a vertex situated in line with or very nearly in line with the seat ring.

Abstract: The invention concerns a preform for a container made of plastic material, comprising a cylindrical body that extends along an axis of revolution of the preform and a bottom that closes the cylindrical body. The bottom has an outer profile with a central portion and a curved portion joining the central portion to the cylindrical body. The central portion has, in longitudinal cross-section, a first concave section. The curved portion has successively, in longitudinal cross-section, from the first concave section towards the cylindrical body, a first convex or frustoconical section, a second concave section and a second convex or frustoconical section.
