Abstract

A housing assembly has an upright back with side channels which carry a cartridge supporting bracket on which is mounted a removable liquid soap cartridge. A casing hinged at the bottom to the back and snapped to the top of the back, encompasses the cartridge and bracket when the casing is closed. A squeese nozzle connected to the cartridge protrudes out of the bottom of the casing and is activated when a plunger on the casing is depressed toward the bracket to squeeze the nozzle, therebetween.

Claims

1. A housing for a liquid dispenser for dispensing liquid soap and the like comprising:

(a) a back member for being received and held in an upright position against a vertical wall;

(b) a front casing proturuding forwardly from said back member, said front casing having a front panel, a pair of spaced opposed side panels joined by their front edges to said front panel, a top panel joined by its front edge to said front panel, and a bottom panel joined by its front edge to said front panel, the side edges of said side panels, said top panel and said bottom panel being joined so that said front panel, said side panels, said top panel and said bottom panel define an open interior and the rear edges of said side panels, said top panel and said bottom panel define an open rear end for said casing;

(c) a hinge member connecting said bottom panel and back member, said hinge member having bases respectively secured to said back member and said bottom panel, a hinge tongue protruding from one of said bases and a stationary hinge pin carried by said hinge tongue, said hinge pin being of a thickness greater than the thickness of said hinge tongue, the other of said bases carrying an arcuate pin receiving member partially surrounding said pin for confining said pin for limited pivotal movement within said pin receiving member when said casing is moved from an upright closed position, in which said open rear end is adjacent to said back, to an inclined forwardly and upwardly open position;

(d) a friction latch for frictionally joining the upper end portions of said casing and said back member when said casing is in its closed position.

2. The housing defined in claim 1 wherein one of said bases is secured flat against the lower end portion of said back member, said arcuate pin receiving member having a slot extending along substantially the entire length of said member, the width of said slot being greater than the thickness of said hinge tongue.

3. The housing defined in claim 1 wherein said back member includes a back plate and a pair of spaced opposed channel members forming inwardly opening channels, said one of said bases being received between said channel members within said channels, said tongue protruding forwardly from said one of said bases.

4. The housing defined in claim 1 wherein said hinge tongue is elastomeric and said hinge pin is elastomeric, being integrally joined to said hinge tongue.

5. The housing defined in claim 1 wherein said one of said bases and said hinge tongue and said pin are integrally joined together, being an extruded L-shaped member in which the said hinge tongue is joined to its associated base.

6. The housing defined in claim 1 wherein said friction latch includes a first base, a forwardly protruding latch tongue mounted to said first base, a latch pin, carried by of said latch tongue, and a second base mounted on the inside surface of said top panel, said second base having a yieldable arcuate latch element adapted to extend partially around said latch tongue when said casing is in its closed condition, said latch pin being thicker than said latch tongue whereby said latch pin will be held within said latch element and will yieldably be released by said latch element when said casing is urged forwardly.

7. The housing defined in claim 6 wherein said hinge pin and said hinge tongue of said hinge member are respectively substantially identical in construction to said latch pin and said latch tongue of said friction latch.

8. The housing defined in claim 7 wherein said hinge tongue and its base and said hinge pin are integrally joined unitary members formed of an extrusion, said hinge tongue of said hinge member and its associated base being respectively flat rectangular members joined along a common edge and being generally perpendicular to each other, said hinge pin being a cylindrical member extending throughout the length of outer edge of the hinge tongue.

9. The housing defined in claim 8 wherein said latch tongue and said latch pin and the base associated with said latch tongue are integral unitary members and wherein the said latch tongue and its associated base are rectangular members joined along a common edge and said friction pin extends along an outer edge of said tongue, throughout its length.

10. The housing defined in claim 9 wherein said back member includes a flat back plate and a pair of opposed parallel channel members extending forwardly from said back plate, said channel members defining inwardly opening channels respectively receiving the bases of one of said hinge members and one of said latch members.

11. housing defined in claim 10 including a cartridge supporting bracket carried by said back member, said cartridge supporting bracket including a U-shaped member having a rectangular front plate, a pair of opposed side plates connected by their edges to said front plate, and a pair of diverging feet extending respectively into the channels of said channel members, said cartridge supporting bracket being disposed within said casing when said casing is in its closed position, for supporting a cartridge containing liquid soap therein and for receiving along said front plate a nozzle assembly depending from the front portion of said cartridge and means for removably retaining said nozzle assembly in place adjacent to said front plate.

12. The housing defined in claim 11 wherein said means for removably retaining said nozzle assembly in place includes a clip having a flat base and a pair of forwardly extending brackets extending forwardly from said flat base, said front plate having a pair of opposed channel members integrally formed on the front surface thereon and receiving the edges of said flat base, said forwardly extending brackets being spaced from each other sufficiently to receive therebetween said nozzle assembly and having inwardly turned fingers on the outer ends of said forwardly extending brackets.

13. The housing defined in claim 12 including a platen plate received above said clip, a movable plunger assembly carried by said front panel of said casing, said plunger assembly including a plunger loosely carried by said front panel, a press plate carried on the inner end of said plunger and a knob disposed on the outer end of said plunger.
