Abstract
A paint pouch fitting for a paint dispensing system comprising a piston slidable within a housing. A passage in the housing includes an inlet communicating with a paint pouch, and an outlet. The passage also includes a piercable membrane positioned between the inlet and the outlet. The piston includes a blade for piercing the membrane. The positioning of the piston within the passage defines two working positions allowing for four operational modes of shipping, piercing, dispensing, and storing.
Claims23
A paint pouch fitting comprising:
- a housing having a chamber with an inlet port and an outlet port and a piercable membrane extending at least partially into the chamber and originally preventing fluid communication between the ports;
- a piston slidable within the chamber between an open, first position and a closed, second position, the membrane being located in the chamber such that it is pierced upon an initial movement of the piston to the second position.
A paint pouch fitting comprising:
- a chamber having a piercable membrane and an end port therein;
- and,
- means for both piercing the membrane and closing the end port during a same motion.
A paint pouch fitting comprising:
- a valve body having a first port and a second port defining a fluid passageway therebetween;
- a piercable membrane covering the fluid passageway;
- and
- a blade slidable within the fluid passageway for piercing the membrane.
A fitting adapted for controlling fluid flow comprising:
- a housing having an elongated chamber and an inlet and an outlet selectively communicating with the chamber;
- a membrane provided in the chamber and interposed between the inlet and outlet for producing fluid flow until the membrane is pierced;
- a piston received in the housing chamber movable between an open, first position and a closed, second position for controlling flow between the inlet and outlet;
- and
- a membrane piercing member operatively mounted for movement with the piston for piercing the membrane upon initial movement of the piston from the first position to the second position.
