Procedure for the production of an assembled object

The method of moulding an assembled cap and tube container comprising at least two separable parts which are ejected from their common mold while joined together, wherein the separable parts can be separated and reassembled manually, the parts comprising an internally threaded cap for a tube and a tube with an externally threaded neck portion, having at least a mating portion adapted for the releasable mating engagement within the internally threaded cap, the cap and the mating portion of the externally threaded tube representing opposing surfaces, respectively, adapted for releasable mating engagement to releasably secure the cap to the tube, the method comprising the steps of:

• moulding the first part;
• allowing the first part to harden for serving as a mold part for the molding of at least one second part;
• molding of the second part;
• removing the assembled object from the mold with the parts joined together, the tube with the cap mounted on top of the tube so that the cap does not need to be placed on the tube after the casting.

An apparatus for molding an assembled object, the object comprising at least two separable parts, the parts comprising a first part having an inner surface having releasable mating formations and a second part or parts having a mating outer surface portion with corresponding mating formations for releasable mating engagement with the inner surface of the first part to releasably secure the parts together, the apparatus comprising:

• an outer mold part having an internal cavity and an internal surface forming a cavity shaped for forming the outer surface of an assembled object;
• an inner core positioned within said internal cavity and having an outer surface spaced in at least some areas from the internal surface of the outer mold part, the outer surface of the inner core being shaped for forming internal surfaces of the first part;
• and
• the inner core comprising at least one core part, having an outer surface portion shaped to form mating inner surface formations on the first part, and being movable between a first position in which the outer surface portion faces an opposing portion of said outer mold part to form a mold cavity for molding the first part, and a second position in which the mold cavity is increased for molding the second part or parts, whereby the inner surface of the first part forms part of the mold cavity for molding the second part or parts.
