The bottom having a concave arch that extends from the seat towards a central zone. A height H of the cheek and a width L of the seating plane are such that 0.5 ≤ L H ≤ 2.5 . A transverse extension A of the seating plane and a transverse extension B of the body, measured near the bottom, are such that A B ≥ 0.85 .
Abstract:
Stackable container (1) having a body (2) and a bottom (3) comprising: an annular seat (10) defining a seating plane (11) complementary with a peripheral face (8) provided on a shoulder (4); a conical arch (14) that extends from the seat (10). In this container: an outer transverse extension Dext of the seat and an overall transverse extension D of the body are such that: Dext D ≥ 0.8 the arch (14) has a peripheral section (17) complementary with a frustoconical surface (7) of the shoulder (4), the seating plane (11) and the peripheral support section (17) define a contact surface, the projection of which on the seating plane (11) has a surface area SC such that: Sc S ≥ 0.4 where S is the surface area delimited by an outer perimeter (12) of the seat (10).
Abstract:
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 includes a seating surface forming a standing plane of the container. In example embodiments, the standing plane has an oblong closed curved shape extending along a longitudinal median axis and a transverse median axis. In example embodiments, the standing plane 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:
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 one-piece mold element (3, 7) for a mold (1) for manufacturing containers from blanks of plastic material by blow molding or stretch blow molding. The mold element (3, 7) includes a one-piece molding wall (4, 8) having a raised molding surface (5, 9) bearing the imprint of at least one portion of a container, the molding wall (4, 8) having at least one decompression vent (20) extending therethrough, the hole leading, via an inner opening (21), onto the molding surface (9), which is provided in the form of a slot.
Abstract:
A one-piece mold bottom (7) for a mold (1) for manufacturing containers, includes a molding wall (8) having a raised molding surface (9) bearing the imprint of at least one portion of a container bottom. The mold bottom (7) includes a cavity (27) integrally formed with the mold bottom (7), defined by a surface casing (29) defined entirely by the mold bottom (7) and including an inner surface (31) of the molding wall (8), opposite the molding surface (9) and matching the raised pattern thereof, and a rear surface (32, 33) opposite the inner surface (31). The mold 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:
A mold (11) for manufacturing a container (2) having a body (4) and a bottom (6), including: an annular peripheral base (8) defining a positioning plane (9); an arch (10) which extends concavely toward the inside of the container (2) from the base (8), the mold (11) including: a wall (12) having an inner surface (13) forming the cavity of the body (4) of the container (2) and having an opening therethrough, the wall (12) having an edge (23) forming the cavity of the positioning plane (9); a mold bottom (14) which is moveably mounted relative to the wall (12), the mold bottom (14) having an upper surface (15) forming the cavity of the arch (10), and a skirt (19) having an outer radial extension that is strictly lower than an inner radial extension of the positioning plane (9).
