A process for producing bodies of polymeric material having an outer shell and a core of foamed material is disclosed. The process includes the steps of: providing a mold having a pair of separable half-molds arranged facing each other; extruding a tubular thermoplastic parison between the half-molds; closing the half-molds around the parison, thereby defining a hollow space between the parison and walls of the mold; injecting into the inside of the parison a thermoplastic polymeric material admixed with a physical blowing agent, the parison expanding into contact with the walls of the mold, and conforming to the shape of the mold; and removing the article form the mold.

A device for moulding articles of composite material includes a pressurizable gasket and an injection head the end of which is flush with the impression of the mould. After low-pressure filling the mould impression with jets of resin and catalyst so oriented as to secure the mutual mixing thereof, the pressurizable gasket allows the half-moulds to be further approached to each other and obtaining thereby the impregnation of the reinforcer element previously charged into the mould impression.

A folding case of polymeric material comprises two equal elements which can be coupled in a rapid way. Each element comprises a side wall of the case articulated, by means of film hinges, to a base panel and to two side panels suitable for defining, respectively, a half portion of the bottom wall and half portions of side folding walls of the case.

Folding case for fruit and vegetables

an apparatus for producing bodies of polymeric material having an outer shell and a core of foamed material is disclosed. The apparatus includes an extruder and accumulation chamber for extruding a tubular element, i.e., a parison, and a second extruder and accumulation chamber for injecting a foamable polymeric material for forming the core of the body inside the parison. The injection occurs inside the walls of a mold, which causes the tubular parison to undergo swelling due to the expansion of the foamable material until the parison conforms to the shape of the mold.
