Abstract (en)
[origin: WO2005032969A1] Disclosed is a feeding piston for a single-use dispenser comprising a receptacle (6) that tapers in a slightly conical manner. The inventive feeding piston is provided with a piston element (2) and a holding element (4) which prevents the feeding piston from moving counter to the conveying direction. The holding element (4) is made of plastic and encompasses different holding segments (30) whose contact surfaces (36) can be placed against the interior peripheral surface of the receptacle (6). The holding segments (30) differ from each other insofar as the final points of the contact surfaces (36) are located at different distances from a center (34) of the holding element (4).
