  • Patent number: 4693286
    Abstract: A piston is forced in a direction to disengage from a cylinder containing a fluid such as an adhesive. The piston while in engagement with the cylinder abuts a stop in response to the disengagement force. While the disengagement force is kept on the piston, the chamber between the fluid and piston in the cylinder is evacuated. After evacuation, the disengagement force on the piston is gradually released and the piston is forced against the fluid to squeeze the fluid through fluid couplings into an array of corresponding containers releasably secured to the piston, simultaneously filling the containers without exposing the fluid to air.
