Claims

1. 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 an extremely flexible bag having front and back walls, having edges side-seamed together and 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 said 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;

said cover having pressing means for pressing a bulge in the bag'"'"'s front wall at a position spaced from at least one of its side edges, and extending towards the bag'"'"'s back wall at a position above said 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, the bulge preventing forward sagging of the bag'"'"'s front wall from closing communication between the bag'"'"'s main and dispensing portions.

2. The fixture of claim 1 in which said pressing means comprises said cover being formed with a wall covering the suspended bag'"'"'s front wall and having an indent which presses into the front wall.

3. 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 an extremely flexible bag having front and back walls having edges side-seamed together and 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 said 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, said cover having a pressing means for pressing a bulge in the bag'"'"'s said upper wall to actuate the operator of the valve, said dispensing nozzle and nozzle hole being shaped to form an interfitting key and key hole respectively so as to prevent an otherwise shaped dispensing nozzle of another but otherwise corresponding liquid dispenser from being contained operatively by the fixture.

4. The fixture of claim 3 in which said dispensing nozzle and nozzle have slidably interfitting cylindrical shapes one of which has an axially extending rib and the other of which has an axially extending groove in which the rib slidably fits.

5. 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 an extremely flexible bag having front and back walls having edges side-seamed together and 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 said 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;

said cover having pressing means for pressing a bulge in the bag'"'"'s front wall at a position spaced from at least one of its side edges, and extending towards the bag'"'"'s back wall at a position above said 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, the bulge preventing forward sagging of the bags front wall from closing communication between the bag'"'"'s main and dispensing portions, and in which the cover is hinged to the front end of the bracket'"'"'s shelf so to swing forwardly and downwardly and give free access to the bracket'"'"'s upstanding plate and shelf, the bracket'"'"'s upstanding plate being flat and having a vertically slidable flat latch bar mounted on the plate behind the back wall of the bag'"'"'s main portion, the latch bar having its top forming a cross head with forwardly projecting pins and the bag'"'"'s top having holes through which the pins extend so as to suspend the bag'"'"'s main portion on the bracket'"'"'s plate, the latch bar having a bottom end projecting through a hole in the bracket'"'"'s shelf and shaped for engagement by a person'"'"'s finger, the latch bar having a top forming a latch for normally holding the cover closed.

6. The fixture of claim 5 in which said latch bar forms oppositely extending cantilever spring arms and the bracket'"'"'s plate has means for engaging the ends of the arms at their bottom so as to cause the latch bar to be spring-biased upwardly to a latching position with the cover, the latch bar being an integral plastic injection molding.

7. The fixture of claim 6 in which the bracket'"'"'s shelf has an inclined portion extending towards and to said upstanding plate and the hole through which the latch bag'"'"'s bottom end projects, the bracket having depending side walls adapted to conceal the latch bar'"'"'s bottom end from horizontal viewing.
