The invention relates to a container made of a plastic material, provided with a body (5) and a bottom (6) extending at a lower end of the body (5), wherein the bottom (6) includes: an annular seat (7) extending substantially away from the body (5) and defining a support surface (8) and an inner annular flange (11) substantially perpendicular to the support surface; a concave arch (13) which extends from an area adjacent to the seat (7) towards a central area (14). The axial dimension H of the flange and the radial dimension L of the support surface are such that: formula (I). 0.6 ≤ L H ≤ 1.5 ( I )
摘要:
Mold for manufacturing, by blowing blanks made of plastic material, containers having a body and a bottom and a wall defining a cavity around a principal axis of the mold and a lateral surface. The wall has, in a lower part, an opening defining a passage for a mold bottom, an upper surface that confers at least in part the shape to the bottom of the container, with said opening having an upper edge. The mold, in any plane containing the axis of the wall: the ratio between a transverse dimension of the upper edge of the opening and a transverse dimension of a lower end of the lateral surface of the wall is greater than 0.95, and the tangent to the lateral surface of the wall, at the lower end thereof, forms with the axis of the wall an angle equal to or less than 30°.

The invention relates to a preform which includes, centred on a single axis xx′: a neck (5), a cylindrical body (12), and a sealed spheroidal bottom (13), and is defined relative to the dimensions of a predefined bottle model (1) which includes: a bottom (3), a body (2) and a neck (5), said neck (5) of said bottle model (1) being identical to the neck of said preform (11).
摘要:
Container (1) of plastic material, comprising a body (5) and a bottom (6), the bottom (6) having an annular outer seat (8) defining a principal seating plane (9) for the container (1), and a deformable membrane (10) that extends radially inside the annular outer seat (8) and is arranged to be able to adopt two configurations: a retracted configuration, in which the membrane (10) extends axially above the principal seating plane (9); a deployed configuration, in which the membrane (10) comprises an annular inner seat (14) in the form of an annular bead projecting towards the exterior of the container (1), which extends axially beneath the principal seating plane (9) and defines a secondary seating plane (15), the bottom (6) comprising a series of hollow reserves (20) in the annular inner seat (15) [sic], which form local discontinuities of the secondary seating plane (15).

Container (1) made of plastic material comprising a body (2) and a petaloid bottom (3) extending the body (2), the bottom (3) comprising a bottom wall (4) that is generally convex towards the exterior, from which feet (5) protrude that are formed by excrescences, the feet being separated side by side by portions of the bottom wall forming hollow valleys (13) that extend radially from a central zone (6) of the bottom to a periphery (7) of the bottom, characterized in that each valley (13) widens out from the central zone (6) towards the periphery (7) and has a concave portion (15) located near the periphery (7).
摘要:
Container, made of a thermoplastic such as PET, having a body oriented along a longitudinal axis with a wall enclosing the axis defining two faces separated from each other by two connecting regions. The body is provided with one groove extending partly over the two faces of the body and one of the two connecting regions, wherein the one groove extends approximately in a plane at right angles to the axis of the body with a depth which is variable between a first depth P1 in the two faces of the body and a second depth P2 in the connecting region. The ratio P1/P2 between the two depths is between zero and a value less than or equal to 0.5.
摘要:
A thermoplastic container obtained by blow-molding of a preform, with a base including in its central part a multiple-branch cross-shaped impression provided with a central recess from which radial branches radiate; the base is of the petal-shaped type with at least three legs formed by protuberances located near the periphery; there are as many legs as branches mutually aligned radially; each leg includes a notch for absorbing stresses radially separated from the end of the respective branch.
