## Abstract

A dispenser for dental floss comprises a closed container having a reel of dental floss disposed therein, and having a generally planar back and front face, a pair of opposed side faces, a bottom face, and a top face opposed to the bottom face. There is a hub centrally located in the interior of the closed container, the reel of dental floss is mounted for rotation about the hub when the dental floss is unwound and removed from the reel. A slot is formed in the top face near a first corner of the container, through which slot a strand of dental floss extends so as to be unwound from the reel. A channel is formed at a second corner of the container, at the intersection of the top face and a second side face, and the channel extends between the top face and the second side face. A friction and cutting member comprises a tongue portion which is angled away from a base portion thereof, and is secured in place within the channel. The top face is concave on a centrally located axis extending between the back face and the front face, the concavity being defined by ridges located at the first and second corners. Thus the slot is located in the first ridge at the first corner, and the channel extends through the second ridge at the second corner.

## Claims

### Claim 1

A dispenser for dental floss comprising:
a closed container having a reel of dental floss disposed therein, said container having a generally planar back face, a generally planar front face, a pair of opposed side faces, a bottom face, and a top face opposed to said bottom face;
a hub centrally located in the interior of the closed container and extending between the interior surfaces of said front and back faces, in the region occupied by said hub, and a reel of dental floss being mounted for rotation about said hub when said dental floss is unwound and removed from said reel;
a slot formed in said top face near a first corner of said container, through which slot a strand of dental floss extends so as to be unwound from said reel;
a channel formed at a second corner of said container at the intersection of said top face and a second side face, said channel extending between said top face and said second side face; and
adhesive means on the substantially planar back face, whereby a dental floss dispenser may be adhesively mounted to a mounting surface;
wherein said friction and cutting member is secured in place within said channel;
wherein said channel extends through said second ridge at said second corner;
a friction and cutting member comprising a tongue portion which is angled away from a base portion thereof, and being secured in place at a second corner of said container at the intersection of said top face and a second side face;
wherein said top face is concave on a centrally located axis extending between said back face and said front face, the concavity thereof being defined by ridges located at said first and second corners; and
wherein said slot is located in a first ridge at said first corner.

### Claim 2 (depends on 1)

The dental floss dispenser of claim 1, wherein said top face is sloped forwardly and downwardly in the region of the concavity formed therein.

### Claim 3 (depends on 2)

The dental floss dispenser of claim 2, wherein said back face extends above said top face in the region of the concavity formed in said top face.

### Claim 4 (depends on 1)

The dental floss dispenser of claim 1, wherein said channel is sloped upwardly and rearwardly within said second ridge.

### Claim 5 (depends on 1)

The dental floss dispenser of claim 1, wherein said container is molded from a plastics material, and said friction and cutting member is formed from metal.

### Claim 6 (depends on 1)

The dental floss dispenser of claim 1, wherein said adhesive means comprises a flexible plastic tape having an adhesive coating on at least a portion of each of the two sides thereof.

### Claim 7 (depends on 6)

The dental floss dispenser of claim 6, wherein said flexible plastic tape is stretchable, and wherein a second portion on each of the two sides thereof has no adhesive coating therein; and
wherein the uncoated portion of the flexible plastic tape forms a graspable tab to facilitate removal of said dispenser from a mounting surface when adhered thereto.
