Abstract

A liquid soap dispenser includes a base used to be attached to a wall of a public toilet. A clamping device is formed with the base for clamping two liquid soap receiving bottles equipped with liquid soap discharging controllers. When the controllers are pushed, a predetermined amount of liquid soap will flow out of the bottles. A mounting portion is integrally formed along a top of the base and defines two lugs at two sides thereof and first inclined surfaces located just below and beside the lugs and second inclined surface located generally in front of the lugs. A cover defines a pair of mounting pins pivotably connected with the lugs and a pair of locating tabs. The cover is movable between a closed position and an opening position wherein in the closed position the locating tabs are located at a rear side of the mounting portion and when the cover is moved to the opening position the locating tabs are moved from the rear side of the mounting portion through the first inclined surfaces to engage with the second inclined surfaces to be retained thereon.

Claims

1. A liquid soap dispenser, comprises:

a base (10) used to be fixedly attached to a wall, said base (10) comprising;

a clamping device integrally formed with the base (10), said clamping device comprising at least an upper clamp (11) and at least a lower clamp (12);

at least one arcuate supporting plate (120) integrally formed with the base (10) and located below and between the lower clamp (12); and

a cover mounting portion (15) laterally formed along a top of the base and defining two lugs (150) respectively on two sides thereof, each lug (150) defining a mounting hole (151) and said cover mounting portion (15) further defining two first inclined surfaces (152) respectively located just below and beside the mounting holes (151) and two second inclined surfaces (153) located respectively generally in front of the mounting holes (151);

at least one bottle (30) for receiving liquid soap, the bottle (30) defining a neck (31) engaging with the upper clamp (11);

at least one liquid soap discharging controller (40) provided in a bottom of the bottle (30), said controller (40) engaging with the lower clamp (12) and supported by the supporting plate (120), when the controller (40) is pushed, a predetermined amount of liquid soap will flow out of the bottle (30);

a cover (20) attached to the base (10) and movable between a closed position and an open position, said cover (20) defining a front wall, two side walls, two mounting pins (21) projecting inwardly respectively from inner faces of the two side walls and two locating tabs (22) located respectively behind the mounting pins (21), said mounting pins (21) pivotably engaging respectively with the mounting holes (151) defined in the mounting portion (15), whereby when the cover (20) is in a closed position, the cover (20) covers the bottle and the clamping device and the locating tabs (22) are located in a rear side of the mounting portion (15), and when the cover (20) is moved from the closed position to the open position in which the cover (20) is substantially perpendicular to the base, the locating tabs (22) are moved from the rear side of the mounting portion (15) through the first inclined surfaces (152) to engage with the second inclined surfaces (153) and are retained thereon.

2. A liquid soap dispenser in accordance with claim 1, wherein the bottle (30) is made of transparent plastics material and has a front side defining a circular protrusion (32) and the cover (20) defines at least one circular opening (23) and wherein when the cover (20) is in the closed position, said protrusion (32) is fitted within the circular opening (23) whereby a user can check the amount of liquid soap in the bottle (30) through the protrusion (32).

3. A liquid soap dispenser in accordance with claim 1, wherein the liquid soap discharging controller (40) comprises a cylinder (41) supported by the supporting plate (120) and defining two opposite recesses (45) engaging with the lower clamp (12) and a pair of projections (46) defining a guiding channel therebetween, a stem (42) having a first end extending into the cylinder (41) to operably connect with a valve and a second end, a push button (43) fixedly connected with the second end of the stem (42), a rod (47) having a first end fixedly connected with the push button (43) and a second end fittingly extending through the projections (46), and an outlet (44) extending downwardly from the cylinder (41), whereby when the push button (43) is pushed, a predetermined amount of liquid soap will flow out of the bottle (30).

4. A liquid soap dispenser in accordance with claim 1, wherein the base (10) is further formed with at least one hook (14) at a bottom thereof, said hook (14) engaging with a bottom of the cover (20) when the cover (20) is in the closed position.

5. A liquid soap dispenser in accordance with claim 3, wherein the cover (20) is further formed with at least one semicircular opening (24) below the circular opening (23) and the push button (43) is extended through the semicircular opening (24).

6. A liquid soap dispenser in accordance with claim 1, wherein each of the locating tabs (22) defines a triangular tip (220).
