Abstract

A housing for toothpaste dispensing containers able to accommodate various pumps, squeeze-type tubes and replaceable cartridges. The housing allows for toothpaste to be cleanly, accurately and easily deposited onto a toothbrush with the use of one hand. Holders are attachable to the housing to give contamination-free storage of toothbrushes and the unit can be affixed to a vertical surface or remain free-standing on a wash basin counter.

Claims

1. A dispenser for a viscous substance, comprising:

a housing;

a reservoir for said viscous substance;

pump means actuatable to discharge said substance from said reservoir; and

lever means pivotally connected to said housing actuatable between a first at rest position; and

a second pump actuating position, wherein pressing on said lever means using a receptacle intended to receive said viscous substance thereon moves said lever means from said first to said second positions thereof to actuate said pump means and cause a discharge of said viscous substance,

said pump means including a deformable bladder, said deformable bladder having sufficient elastic memory to return to its original configuration when no external pressure is applied thereto, an upper one way valve, said upper one way valve configured to allow flow of the viscous substance into said deformable bladder only, a lower one way valve, said lower one way valve configured to allow flow of the viscous substance out of said deformable bladder only, and deforming means operatively associated with said lever means and being disposed to deform said bladder as said lever means are moved into said puma actuating position thereof, which reduces the volume of said bladder, causing said viscous substance therein to discharge out of said lower one way valve, and whereby said lever means moving into said at rest position thereof allows said bladder to return to its said original configuration, which increases its internal volume, said increase in volume drawing the viscous substance into said bladder through said upper one way valve.

2. The dispenser of claim 5, wherein dispensing of the viscous substance can be accomplished by a user holding said toothbrush using only one hand.

3. The dispenser of claim 5, further comprising an adapter attachable to said lever means, whereby said adapter allows toothbrushes of different sizes and shapes to be used by adjusting the position of the toothbrush relative to said lever means.

4. The dispenser of claim 1, wherein the viscous substance is toothpaste.

5. The dispenser of claim 4, wherein said receptacle is a toothbrush.

6. The dispenser of claim 1, wherein said housing includes at least one detachable container, said detachable container being adapted to hold a toothbrush.

7. The dispensir of claim 6, wherein said detachable container is adapted to hold only a single toothbrush.

8. The dispenser of claim 1 wherein said lever means is normally biased into said first position thereof.

9. The dispenser of claim 8 further including a resilient member for normally biased said lever means into said first at rest position thereof.

10. The dispenser of claim 9 wherein said resilient means is an elastic band disposed between said lever means and said housing for normally biased said lever means into said first at rest position thereof.
