ABSTRACT:
Liquid filled receptacles are made from a thermoplastic flat tube. The flat tube is extruded from plasticized material. A strip of receptacles is formed in a molding assembly from the tube. The strip has groups of pluralities of small receptacles lying one beside the other, the receptacles preferably being ampoules. All of the receptacles of a group of receptacles are filled simultaneously by filler mandrels. The number of filler mandrels corresponds to the number of small receptacles lying adjacent to one another in any group of receptacles, while the group of receptacles are still held in the molding assembly. In the molding assembly, configurational irregularities of are formed in the side flange areas. The irregularities cooperate with a thrust device conveying the receptacle strips from the molding assembly to a punching device, and position the strips in the punching device.
