摘要:
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 )

Spongy mass (4) suitable for being brought into contact with the end wall of a container for a predetermined time, for treating said end wall of the container. Said mass consists of a soft crosslinked foam having semi-open cells and high resilience, has a main face (14) for contact with the end wall of the container and includes blind grooves (15) which open onto said main face (14), but do not emerge on the opposite side, and that are distributed in two sets of mutually transverse grooves (15a, 15b) that define blocks (16). Application: cooling of the end walls of thermoplastic containers leaving a moulding unit; wiping of the end walls of thermoplastic containers.

摘要:
A container, in particular a bottle, made of thermoplastic material produced by blow molding or stretch-blow molding of a heated preform, the container designed to contain a liquid being flat and having a substantially domed base with outward-facing cavity defining a substantially planar peripheral annular seat for being set on a support, the base being provided with several grooves radiating from the base center. Each groove in its zone of intersection with the annular seat, has a portion of substantially increased width and the two edges of that portion of the groove are curved with relatively large radii of curvature and with respective concavities facing one another.
