摘要:
A plastic bottle, wherein reinforcing portions are formed by a circular groove provided around the body of the bottle. The groove comprises, from the base upwards, a lower part to be connected to the body, a central part, and an upper part to be connected to the body. Each of the parts has a constant peripheral profile, the central part having a peripheral profile with simple curvature with a concave part facing outwards of the bottle, the upper and lower parts having each a profile with simple curvature and a concave part facing inwards of the bottle, and the upper and lower parts are each connected tangentially to the body and the central part. The invention is particularly applicable to bottles designed to be filled with carbonated or aerated drinks.
摘要:
A container made of thermoplastic material having a body in which at least one side panel is hollowed out, the container including a central zone having, in a longitudinal plane, a concave profile, and an adjoining zone longitudinally extending the central zone and having, in a longitudinal plane, a convex profile. The central zone and the adjoining zone are stiffened, and the junction between the central zone and the adjoining zone defines a deformable membrane.

A bottom (2) of a hollow body obtained by blowing or stretch-blowing a preform of a thermoplastic material. The bottom (2) includes a transverse support surface (4) and, on either side of the transverse support surface (4), a transverse outer edge (5) and a concave inner wall with a transverse central portion (10) having a pellet (11) of a low-crystallinity material. The pellet corresponds to the injection point of the perform. The bottom (2) has reinforcing ribs (1) having an outer edge (12) adjacent to the outer edge (5) of the bottom (2) as well as an inner edge (13) adjacent to the transverse central portion (10) but not reaching the transverse central portion (10). The reinforcing ribs (1) flare from their outer edge (12) toward their inner edge (13).

摘要:
Thermoplastic container having a body and a base including: a concave arch, a concave dome opening at the center of the arch, an annular zone surrounding the base of the arch and forming a flat foundation, claw-shaped zones radially extending the base of the body and offset projecting outwards relative to the arch, and radial grooves delimited between the zones in the shape of claws. The grooves have bottoms that are formed by radial sections of the arch and that have a radially variable depth maximum in correspondence with said annular zone forming a foundation. The base is adapted for withstanding, without marked deformation, hydrostatic pressure due to the liquid column increased by an excess pressure not exceeding approximately 2×105 Pa.

The invention relates to a bottom of a mould for producing thermoplastic containers, and to a container thus produced. The container (1) produced comprises: a base (4) having a concave peripheral wall (6) extending essentially coaxially to the X-X′ axis, this concavity defining a non null curvature all along the wall (6); an annular region (7) forming a tubular peripheral wall (8) extending essentially coaxially to the X-X′ axis, the transversal radial distance between the X-X′ axis and said wall (8) being longer than the transversal radial distance between the X-X′ axis and any point along the concave peripheral wall (6) of said base (4); and a shoulder (9) forming a connecting region between the base (4) and the annular region (7). The depth of said annular region is between 0.5 and 2%, preferably between 1 and 1.5%, especially 1.2% of the diameter of the annular region (7), and the height of the base (4) is between 5 and 15 mm.

The invention relates to a bottom of a mold (13) for a mold for producing containers, especially bottles, by blow molding or blow drawing, said containers having a body and a bottom (14) of a container, comprising a peripheral base (15) in the shape of a crown, which is connected on the inside to a central area (16) forming an arch consisting of a plurality of radiating impressions (17) alternating with a plurality of radiating projections which are distributed in an angular and equidistant manner about a central axis (Y) of the bottom (14) of the container. For the molding of the central area (16) of the bottom (14) of the container, the bottom (13) of the mold comprises: a plurality of radiating projecting branches (19) distributed in an angular and equidistant manner, and extending approximatively radially to the axis (X) of the bottom of the mold; a central core (20) comprising a lateral wall (21) to which the branches (19) are connected; and in-between sections (22) forming cores of angular sectors regularly separating said branches from each other. The bottom (13) of the mold is characterized in that each radiating projecting branch (19) has an upper part (23) in the form of an inclined platform which descends from the center towards the periphery with at least two points (24, 25) of inflection of the curve.

A thermoplastic container (1) having a body (2) provided with at least one groove (6) that forms a closed loop and that extends perpendicularly to the axis of the body; the groove having a depth (p) that lies in the range 3 mm to 6 mm; in right section, the groove comprises: an bottom (8) that is rounded, having a small radius of curvature (R1) in the range 0.2 mm to 1.5 mm; two faces (9) that are plane and that flare apart from each other on either side of the bottom (8) at an angle (α) in the range 50° to 90°; and two faces (10) that are curvilinear, and that extend away from the respective plane faces (9) at an angle (β) that is less than 180°, and that are connected thereto by respective rounded walls (11) of small radius of curvature (R2) that does not exceed 1.5 mm, and that are connected tangentially to the wall (12) of the body (2). Such a groove (6) is deformable with a capacity to pinch axially in the presence of an axial force applied to the container.
摘要:
A thermoplastic container (1) adapted to be filled with a hot liquid, comprising a body (2) having a plurality of recessed panels (3) parallel to the axis (4) of the body and separated by beams (5) parallel to the axis; the panels are arranged on a number of levels (A, B, . . . ), the panels of two consecutive levels being separated by a collar (6) in surface continuity with the beams; each beam is recessed to form a longitudinal central channel section (7), and the channel sections (7) of the beams (5) of the successive levels are connected to one another, in an angularly offset manner from a beam (5) of one level to the consecutive beam (5) of the adjacent level, by strongly inclined channel sections (8) extending in the collars (6), channel sections (7, 8) forming channels configured as parallel successive steps and distributed over the periphery of the body.
