A fixture for fluid dispensing bags having lower portions with nozzles. The bags are used with the lower portions folded forwardly and the nozzles pointed downwardly. The nozzles form keys which differ for different groups of the bags. The fixture has a forwardly extending shelf for the lower portions of the bags and in which a hole is formed and an insert is positioned in the hole and has a nozzle hole forming a key hole fitted by the nozzles of only one group of the bags.

Fixtures for fluid dispensing bags

A dispensing device for a bag container a liquid, made of flexible material and forming upper and lower walls through which holes are formed for receiving the device, has a tubular lower part with a top flange which is sealed to the inside of the lower wall and depends through the hole in the lower wall. A tubular upper part has a top flange sealed to the inside of the upper wall and depends through the hole in that wall and is telescoped inside the lower part so as to move up and down in the lower part. The top of the upper part forms a piston such as a collapsible dome extending upwardly through the hole in the upper wall and exposed on the outside of the upper wall and therefore exposed on the outside of the bag. The lower part has a lower end having a self-closing valve and has at least one side port normally open to a space between the flanges and therefore between the bag walls. The lower part has one or more ports normally open to that space and through which liquid contained by the bag can flow into the interior of the device. The upper and lower parts are elastically or spring biased apart and when the piston is pressed the upper part moves down into the lower part until stopped by interengaging of the two flanges, forcing open a self-closing valve in the bottom end of the lower part, so that the liquid in the bag is dispensed.

Dispensing device

A wall fixture containing a liquid dispenser, the fixture comprising a bracket having an upstanding plate from the bottom of which a shelf having a nozzle hole extends forwardly and a cover adapted to open and close in front of the plate and shelf, the dispenser comprising a flexible bag having front and back walls containing the liquid and having a main portion with its back wall suspended in front of the plate and a dispensing portion folded forwardly on the shelf so as to form a lower wall, the lower wall having a dispensing valve having a dispensing nozzle extending downwardly through the nozzle hole, and a depressible upper wall above the valve, the valve having an operator between the upper and lower walls and actuated by pressing the upper wall downwardly on the operator; the cover having a pressing arrangement for pressing a bulge in the bag's front wall and extending towards the bag's back wall at a position above the bag's dispensing portion and so as to form a passageway on at least one side of the bulge extending between the main and dispensing portions of the bag when the cover is closed.

Fixture for bag-type liquid dispenser

Hollow shapes are blow molded with a special form of gate connecting the shapes to the parison from which they are blow molded and permitting subsequent degating of the shapes by ultrasonic mechanical vibration applied to the gates.
