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:
A one-piece mould bottom (7) for a mould (1) for manufacturing containers, includes a moulding wall (8) having a raised moulding surface (9) bearing the imprint of at least one portion of a container bottom. The mould bottom (7) includes a cavity (27) integrally formed with the mould bottom (7), defined by a surface casing (29) defined entirely by the mould bottom (7) and including an inner surface (31) of the moulding wall (8), opposite the moulding surface (9) and matching the raised pattern thereof, and a rear surface (32, 33) opposite the inner surface (31). The mould bottom (7) is provided with at least one pair of openings (35; 37) leading into the cavity (27) for circulating a heat-transfer fluid inside the cavity.
Abstract:
The invention relates to a container (1) made of plastic material, including a body (2) that extends along a main axis (X), a shoulder (3) which forms an extension of the body (2) on an upper side, and a base (5) which forms an extension of the body (2) on a lower side, the body having a square cross-sectional shape near the shoulder (3) as well as near 7 the base (5), and a rectangular cross-sectional shape in a median area of the body (2).
Abstract:
Disclosed is a container made of plastic material including a body extending along a longitudinal axis between an opening and a base, the base having: a seat forming a setting plane for the container; a concave arch, rotational around the longitudinal axis and extending from the vicinity of the seat to an amorphous central zone; and stiffening bosses that protrude from the concave arch and that extend radially to the interior of the arch. The stiffening bosses are angularly spaced from one another by alternating first bosses and second bosses that are distributed along: a first annular band in which the first bosses extend; and a third annular band in which the second bosses extend.
Abstract:
A plastics container (1) includes a body (2) with a polygonal section which extends along a main axis (X), a shoulder (4) which extends in continuation of the body (2) on an upper side, a neck (5) which extends in continuation of the shoulder (4), and a bottom (3) which extends in continuation of the body (2) on a lower side, the bottom (3) including: an annular seat (9) defining a standing perimeter (10), having a polygonal contour formed from a plurality of sides and vertices, and approximately perpendicular to the main axis (X); a central peg (16) having a side wall (17) that has a generally axisymmetric frustoconical shape about the main axis (X) and which is connected to the rest of the bottom (3) by a connecting fillet (19) which has a radius that is variable in revolution about the main axis (X) of the container.

Abstract:
The invention relates to a plastic recipient comprising a panel with at least one radius of curvature greater than 100 mm, where the panel has reinforcing means. The reinforcing means includes a peripheral slot defining a reinforcing contour and a plurality of inner slots arranged inside the reinforcing contour. Each inner slot has two ends, where each end opens out into the peripheral slot, or at least one end opens out into another inner slot.
Abstract:
A one-piece mould element (3, 7) for a mould (1) for manufacturing containers from blanks of plastic material by blow moulding or stretch blow moulding. The mould element (3, 7) includes a one-piece moulding wall (4, 8) having a raised moulding surface (5, 9) bearing the imprint of at least one portion of a container, the moulding wall (4, 8) having at least one decompression vent (20) extending therethrough, the hole leading, via an inner opening (21), onto the moulding surface (9), which is provided in the form of a slot.
Abstract:
A container (1) made of plastic material, provided with an oblate body (2) and with a bottom (3) in the extension of the body (2) at a lower end thereof, the bottom (3) including: a peripheral base (7) defining an annular standing plane (8) whose contour exhibits, along a long axis, a large dimension A, and, along a short axis perpendicular to the long axis, a small dimension A′ that is strictly smaller than the large dimension, a concave arch (13) that extends from the base (7) to a central area (14); wherein the base has: along the long axis, a width C such that: 0.03 ≤ C A ≤ 0.1 along the short axis, a width C′ such that: 0.05 ≤ C ′ A ′ ≤ 0.15 .
