Cap assembly and production method

Abstract

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 caps. A cap assemb!y 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 cop element protects the tip on one side. On the other side, unscrewing the cap breaks the upper portion away without hurting a person.
