This comprises core, spreaders and mold described, with an extrusion head. Preferred features: The container is formed using vacuum against the core. It is re-formed under vacuum or air inflation against the hollow two-part mold surrounding the core. The extruded preform is widened by two or more rod-like spreaders (3), or by the core itself.

Blow moulding of thermoplastic containers - with formation of handles and handle recesses in preform during blowing

Prodn. of thermoplastic containers by blow moulding comprises surrounding a tubular preform with a blow mould in which it is blown by introducing a pressure medium, while simultaneously forming handle recesses and handles. Before introducing the preform into the mould, handles with welding lugs are formed from the preforme in a preliminary separate handle mould. These handles are placed in thrust cartridges belonging to the blow mould, and the cartridges are moved into the blow mould while the preform is introduced in its normal length and expanded. These steps are followed by closure of the blow mould, blowing of the container while welding on the handles, and cooling, while new handles for the next container are formed in the handle mould.

Process for blow-moulding or injection-moulding a plastic article

The invention relates to a process for blow-moulding or injection-moulding a plastic article, in which a material in web form is laid in an opened hollow mould and is pressed by the polymer melt in the closed hollow mould by blowing or injecting against the inside wall of the hollow mould, forming a composite article. The material in web form is equipped with a textile layer on the surface side, facing the plastic, so that the polymer melt penetrates into the hollow or intermediate spaces of the textile layer and forms a positive, firmly adhering surface bond between the plastic article and the material in sheet form. Since the adhesive bonding operation required for laminating is dispensed with, the novel process permits an inexpensive, energy-saving and environmentally friendly production of a coated plastic article.

Blow moulding thermoplastics - arms moving mould closure unit being symmetrical about plane through nozzle and blowing point

Hollow thermoplastic articles are blow moulded, using an extruder with tube nozzle, a separate blowing point, and an intermediate moving mould closure unit held on to a frame by control arms or pairs of arms. These arms are positioned symmetrically about the centre plane through the nozzle and blowing point. Access to mould is easy and moving parts move vertically. No torsional stresses is placed on arms which can therefore be light-weight in construction and thus power required is reduced.

Multilayer plastic bottles with mineral filler and foamed layer for improved recylability

Plastic containers exhibiting reduced plastic resin usage, while maintaining a specific gravity of below 1.0, so as to allow their quick and easy separation using floatation techniques during recycling. Within a layer or portion some of the plastic resin of the container body may be replaced with an inorganic mineral filler material, while within another layer or portion of the plastic container, the plastic material (e.g., polyethylene, polypropylene) may be foamed. The fraction of mineral filler material that may be included within the polyethylene may thus be increased beyond that previously possible while maintaining the specific gravity below 1.0, by also foaming a layer or portion of the polymeric material, so as to create voids therein. This allows significantly less resin material to be employed, while maintaining strength characteristics of the plastic container so as to be at least comparable to existing plastic containers not including such mineral filler materials.
