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.

Disclosed herein, amongst other things, is a molded article, such as a preform that is blow moldable to form a container, and a related method of forming and recycling a container. The structure and steps includes injection molding a molded article having tubular body.

A storage system for storing objects of plastic material processed in a bottling line (45) comprises: a plurality of drawers (4) configured to contain groups of objects (5); a frame (2) which defines a plurality of compartments (3) configured to house the drawers (4); a conveyor (8) movable in the storage system (1) itself and configured to access the compartments (3) in such a way as to withdraw and place drawers (4) from and into the compartments (4); a loading bay (11) having one or more loading compartments for receiving corresponding drawers (4) and having a loading manipulator (28) configured to place in the drawers (4) the loose objects (5) received from an infeed conveyor (29); an unloading bay (12) having at least one unloading compartment for receiving a corresponding drawer (4) and having an unloading manipulator (41) configured to place onto an outfeed conveyor (43, 44) the loose objects (5) stored in the drawer (4).

A method comprises the following steps: providing a pre-processed element made of at least one polymeric material, introducing the pre-processed element in a female mould part having a forming cavity, shaping the pre-processed element between the female mould part and a male mould part, the female mould part and the male mould part being movable relative to one another along a moulding direction so as to form a concave object from the pre-processed element.

The forming cavity has a transversal dimension measured transversely relative to the moulding direction, the forming cavity further having a transition zone in which the transversal dimension passes from a larger value to a smaller value, the forming cavity further having a bottom.

During the introducing step, the pre-processed element is placed on the transition zone, so that the pre-processed element rests on the transition zone at a distance from the bottom of the forming cavity.

The invention relates to a new PET preform design that enables a more precise distribution of material in the bottle bottom and avoids the waste of material around the injection point. The thickness BWT.sub.min of the wall at the center of the gate or tip (3) (injection point) is reduced to a minimum in order to avoid the waste of material around the injection point when the preform is blown. This is particular important for carbonated soft drink application since the reduced amount of amorphous material at the center of the gate (3) helps to reduce the risk of stress cracking on the bottle base. Furthermore a step (4) having thickness WT.sub.max in the body wall thickness, in the region of the periphery of the base with WT.sub.max>WT, allows enough material to be available for the proper blowing of the bottle bottom making the bottle more stable.
