Abstract

A wall mountable toothpaste dispenser operated by electrical power from the bathroom outlet or batteries. A sliding horizontal cylindrical wedge presses a toothpaste tube against a fixed vertical planar wedge with an inclined surface for squeezing a dose onto a toothbrush. The cylindrical wedge is moved by a line and pulley system driven by a motor and spur gearing. The dispenser is made from inexpensive materials and any mechanical part can be repaired by the user. Other viscous liquid products can be dispensed by this device.

Claims

1. A toothpaste dispenser comprising:

a plastic housing comprising a small, horizontal upper compartment and an elongated vertical main compartment, the upper compartment being contiguous to the main compartment, the main compartment having a front wall, there being a door in the front wall;

said main compartment comprising a first sidewall and a second sidewall, a rear wall, a top wall, and a concave bottom wall with an outlet aperture;

a vertically disposed planar wedge adjacent to the rear wall with its thinner edge abutting the bottom of said housing, said wedge and housing being dimensioned and configured such that a toothpaste tube can be vertically disposed against the planar wedge with its nozzle protruding from the outlet aperture;

a horizontally disposed cylindrical wedge having a first axle and an oppositely disposed second axle, said cylindrical wedge being pressed against the toothpaste tube and the planar wedge;

a first rod and a second rod, each rod having pulleys proximate to one end as respective first and second pulleys and having respective first and second spur gears at the opposite end;

a third driving spur gear, each first and second spur gear intermeshing with each other, the first spur gear intermeshing with said driving third spur gear;

a first line attached to said first pulley and to said first axle of the cylindrical wedge; and

a second line attached to said second pulley and to said first axle of the cylindrical wedge;

whereby

the cylindrical wedge is slidingly moved down the toothpaste tube by operation of the driving third spur gear to squeeze the toothpaste through the nozzle of the tube onto a toothbrush, and the cylindrical wedge being returned to its original position upon emptying the tube by reversing the operation of the driving third spur gear.

2. The toothpaste dispenser according to claim 1, including a third pulley attached to the second sidewall and below the cylindrical wedge for guiding the second line.

3. The toothpaste dispenser according to claim 1, including means causing reversal of the direction of the cylindrical wedge.

4. The toothpaste dispenser according to claim 1, wherein a length of the cylindrical wedge is coextensive with a flattened diameter of the toothpaste tube.

5. The toothpaste dispenser according to claim 1, including a plastic nozzle cover adapted to being tethered adjacent the outlet aperture for covering the nozzle of the toothpaste tube.

6. The toothpaste dispenser according to claim 1, wherein the dispenser includes means for mounting the dispenser on a vertical wall surface.

7. The toothpaste dispenser according to claim 1, wherein the outlet aperture has a slot for the accommodation of toothpaste tubes with shortened stems.

8. The toothpaste dispenser according to claim 1, there being means defining first and second vertical grooves in the first and second sidewalls, respectively, and wherein the cylindrical wedge has its first axle end supported in a first vertical groove in the first sidewall and a second axle being elongated and its end supported in the second vertical groove of the second sidewall.

9. The toothpaste dispenser according to claim 8, wherein the first and second grooves are inset in the respective first and second sidewalls.

10. The toothpaste dispenser according to claim 1, wherein the first and second lines are monofilament fishing lines.

11. The toothpaste dispenser according to claim 10, wherein the monofilament lines are anchored in apertures having depressions in the second axle, the first pulley and the second pulley by split-shots.

12. The toothpaste dispenser according to claim 1, including an electric motor to drive the third spur gear.

13. The toothpaste dispenser according to claim 12, wherein the first spur gear, the second spur gear, the third spur gear, and the motor are housed in the horizontal compartment.

14. The toothpaste dispenser according to claim 12, including an electrical system to energize the electric motor.

15. The toothpaste dispenser according to claim 14, wherein the electrical system includes a three-way toggle switch.

16. The toothpaste dispenser according to claim 14, wherein the electrical system includes a three-way momentary flip switch.

17. The toothpaste dispenser according to claim 14, wherein the motor is configured to be powered by converted house current.

18. The toothpaste dispenser according to claim 14, wherein the motor is configured to be powered by a battery source.

19. The toothpaste dispenser according to claim 14, including a circuit board in the electrical system, whereby the direction of the cylindrical wedge can be controlled.

20. The toothpaste dispenser according to claim 19, wherein the small horizontal upper compartment comprises a separable module containing the first, second and third spur gears, the electric motor, the electrical system, and the circuit board on the top wall.
