Abstract (en)
[origin: US4792065A] A composite piston for ejecting a plastic mass from a receptacle includes a piston head and a pressure component which in combination form a chamber. The piston head and pressure component are displaceable within the receptacle from an insertion position into a locked position. When being moved into the locked position, a part of the plastic mass flows through an opening in the piston head into the chamber. After the locked position is established, the opening in the piston head is closed by an extension on the pressure component.
