Abstract: A case for the storage and easy wearing of condoms emprises-includes a box-shaped casing defining a containment chamber configured to accommodate a plurality of condoms arranged in respective flattened single-use packages arranged to form a stack. A pusher operates in the containment chamber so that a terminal single-use package of said stack is held against a bottom wall of the chamber itself. An extractor movable between a waiting position in which it engages the terminal single-use package inside the containment chamber and an extracted position in which the terminal single-use package is extracted through an outlet slot arranged in proximity to the bottom wall to expose the respective condom outside the box-shaped casing, in a use condition suitable for wearing.

Abstract: A method and a plant for twin-sheet thermoforming of fuel tanks; first and second sheets (SA, SB) of thermoformable plastic material, are separately fed along respective processing lines (10A, 10B). The sheets (SA, SB) are heated and gripped along their peripheral edges by a pneumatically actuate suction and vacuum holding device (15A, 15B), for supporting the heated sheets (SA, SB) in a substantially flat condition while they are moved towards a respective thermoforming station (16A, 16B). Both the molds (17A, 17B) are disposed side by side with their open cavity facing upwards. After thermoforming of the plastic sheets (SA, SB), one of the molds (17B) is turned upside down onto the other mold (17A), to overlap and weld superimposed sealing areas of the two thermoformed shells (GA, GB). Cooling of the molds and thermoformed tank may be performed on a side of the processing lines (10A, 10B).

Abstract: A method and an apparatus for thermoforming bodies in plastic material with a mold (11). A sheet (15) of thermoformable plastic material is heated to a plasticization temperature, supporting it along its peripheral edges. The heated sheet (15) is pre-shaped to create an enrichment of material, performing a sag by relative movements for approaching, raising and/or rotating its peripheral edges, maintaining the plastic sheet (15) in a suspended condition. The pre-shaped sheet (15) is then brought into close contact with the mold (11) and vacuum-formed making it adhere to the shaping surface (12) of the mold, (11).
