A nozzle tool system for extrusion blow molding has an intermediate module and at least first and second nozzle outlet units, each forming an adjustable nozzle outlet gap between a mandrel extending axially and a deformable sleeve. The units can be connected with the intermediate module as replacements for one another, and have a first outlet diameter and a larger second outlet diameter different from one another. At least one setting drive for reversible deformation of the sleeve is arranged on the intermediate module and can be connected with the deformable sleeve by way of a releasable coupling arrangement. The first nozzle outlet unit delimits a first setting path of the setting drive, using at least one inner mechanical stop, and the second nozzle outlet unit delimits a second setting path of the setting drive, greater than the first setting path, using at least one inner mechanical stop.

Article having a body portion including one or more walls surrounding an interior space. The one or more walls have an inner surface, an outer surface, a wall thickness, a transparent portion, and one or more aesthetic regions having oblong voids provided between the inner surface and the outer surface within an outermost 70% of the wall, and the one or more aesthetic regions are provided in a predetermined pattern.

A copolymer of propylene with hexene-1 containing from 5 to 9% by weight of recurring units derived from hexene-1, having a melting temperature from 125 to 140 and Melt Flow Rate (ASTM D1238, 230/2.16 Kg) from 0.1 to 3 g/10 min., is used to produce blown films having valuable mechanical and optical properties.

A plastic container having a sidewall defining a chamber and having a first end and a second end and an opening at the first end into the chamber. A base of the container extends from the sidewall and closes the second end, the base having an outer perimeter portion defining a support structure, an axially inwardly extending perimeter wall spaced radially inwardly from the support structure forming an angle with a horizontal line of greater than about 80, a centrally disposed pushup section in the shape of an axially inwardly extending truncated cone, and a toroidal-shaped channel circumscribing and connecting the perimeter wall to the pushup section. The toroidal-shaped channel has a surface that is asymmetrical about a central axis of the container when the container is under static pressure conditions.

An accumulation extruder head comprises a head body (10) which has an accumulation chamber (13a) with a vertical axis, designed to be filled with a load of thermoplastic resin, and a bottom outlet mouth (11) for expulsion of the load of thermoplastic resin in the form of a tubular parison. A piston (18) is coaxially inserted inside the accumulation chamber (13a) and is movable in a reciprocating manner inside the accumulation chamber along the vertical axis in an expulsion direction and an upward direction. A mechatronic assembly (30) comprises an output element (31), which is linearly displaceable along the vertical axis between a raised position and a lowered position, and a plurality of electric actuators, each able to rotationally drive a respective rotating element coupled to the output element (31) so as to displace the output element in the vertical direction. The output element (31) cooperates with a pusher assembly (40), which is rigidly coupled to the piston (18) for displacement therewith so as to push the piston (18) in the expulsion direction.
