A preferably air-tight and liquid-tight collapsible container comprises a container body () formed of a sheet material, said sheet material having two thermoplastic surfaces (), said sheet material comprising a preferably fluid-tight carrier foil () provided at least on and preferably on both sides (), with a thermoplastic semi-rigid or rigid layer material, preferably a polyester based material said sheet material being folded to a container-like body and sealed in the overlapping edge regions () to form a container-like body, said container-like body being coated with a sheathing () of elastomeric thermoplastic material of the same kind or type as the foil material to form a container body (), said container body () being provided at one open end () with a container head formed from thermoplastic material of the same kind or type as the foil material.

Polyfoil tube made from semi-rigid or rigid foil materials

The invention relates to a tip cap assembly for closing a distal opening of a receptacle like a syringe body or a tube in a sealed manner, and to a method for producing the tip cap. A cap assembly according to the invention comprises a frangible tip of a receptacle, preferably a pre-filled receptacle. An upper portion of the tip closes the receptacle respectively a lower tip portion comprising a passage as known from the state of the art. Hence, the receptacle is reliably sealed to prevent contamination or loss of the medication. Compared with the state of the art, a receptacle has a more effectively sealed tip. It is necessary to break the upper tip portion away in order to open the receptacle. A cap element protects the tip on one side. On the other side, unscrewing the cap breaks the upper portion away without hurting a person.
