  • Publication number: 20120031904
    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 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.

  • Publication number: 20110288505
    Abstract: The invention relates to a method for storing and supplying a liquid, especially a liquid medical preparation. The invention further relates to a receptacle for storing and supplying a liquid, especially a liquid medical preparation. It is an object of the invention to provide a suitable receptacle and method for storing and supplying a desired liquid quantity. The object of the invention is solved by a receptacle for storing and supplying a liquid which receptacle is liquid tight and preferably gas-tight comprising a tube or a foil bag which can be compressed. The tube or foil bag preferably comprises a rigid opening portion sealingly mounted to one end of the tube. The diameter of the opening portion preferably is the same as the diameter of the tube. The rigid opening portion is stable in respect of shape. The tube diameter preferably is not more than 10 mm and, in an embodiment of the invention, the tube contains a liquid, preferably a liquid medical preparation.

  • Publication number: 20100294791
    Abstract: What is proposed is a dispensing device for dispensing tablets belonging to a stack of tablets separately. There is arranged, in a casing (100), a conveying element (200) which can be moved to and fro, in relation to said casing, between a dispensing position and a conveying position. The dispensing device also comprises holding means, in particular a lift element (300), which cause the stack of tablets to be kept stationary when a movement of the conveying element, relative to the casing, from the dispensing position into the conveying position occurs, and which cause said stack of tablets to be entrained towards the removing aperture by the conveying element when said conveying element returns to the dispensing position. In this way, the stack of tablets is conveyed in the direction of conveyance by a predetermined amount, particularly by the thickness of a single tablet, when a forward-and-backward movement of the conveying element occurs, and said single tablet can be easily removed.
