## Abstract

A disposable dental waste filter device has a body having a receiving end, and a separable cap having a tip end, the body for receiving and capturing therein amalgam that enters into the body through the tip end and the separable cap. A disposable dental waste filter device also has a body having a receiving end, a central lumen for receiving and capturing amalgam, a filter, and a circular leg portion having an exterior channel, and a separable cap having a tip end, a circular outer rim having a circular end ridge portion with the ridge portion adapted to be inserted into the exterior channel of the body for a snap fit engagement between the cap and the body, the body for receiving and capturing therein amalgam that enters into the body through the tip end and the separable cap.

## Claims

### Claim 1

A disposable dental waste filter device comprises:
a body having a receiving end, a central lumen for receiving and capturing amalgam, and a circular leg portion having an exterior channel; and
a separable cap having a tip end, a circular outer rim having a circular end ridge portion with the ridge portion adapted to be inserted into the exterior channel of the body for a snap fit engagement between the cap and the body, a circular inner rim, an annular channel formed between the circular outer rim and the circular inner rim, the body for receiving and capturing therein amalgam that enters into the body through the tip end and the separable cap, and
a filter being captured within the annular channel formed between the circular outer rim and the circular inner rim
a flap in the body to prevent any captured amalgam from escaping from within the body.

### Claim 2 (depends on 1)

The disposable dental waste filter device of claim 1 wherein the annular channel formed between the circular outer rim and the circular inner rim has a rounded end.

### Claim 3 (depends on 1)

The disposable dental waste filter device of claim 1 wherein the body and the cap are constructed of plastic.

### Claim 4 (depends on 1)

The disposable dental waste filter device of claim 1 wherein the flap may be moved into a closed position or an opened position.

### Claim 5 (depends on 1)

The disposable dental waste filter device of claim 1 further comprising a second filter positioned within the body for preventing amalgam that enters into the body from escaping through the receiving end.

### Claim 6 (depends on 5)

The disposable dental waste filter device of claim 5 wherein the second filter is puck like in shape.

### Claim 7

A disposable dental waste filter device comprises:
a body having a receiving end, a central lumen for receiving and capturing amalgam, a filter, and a circular leg portion having an exterior channel; and
a separable cap having a tip end, a circular outer rim having a circular end ridge portion with the ridge portion adapted to be inserted into the exterior channel of the body for a snap fit engagement between the cap and the body, a circular inner rim, an annular channel formed between the circular outer rim and the circular inner rim, a
circular ring, an annular channel formed between the circular ring and the circular inner rim, the body for receiving and capturing therein amalgam that enters into the body through the tip end and the separable cap: and
a filter being captured within the annular channel formed between the circular outer rim and the circular inner rim
a flap in the circular ring to prevent any captured amalgam from escaping from within the body.

### Claim 8 (depends on 7)

The disposable dental waste filter device of claim 7 wherein the body and the cap are constructed of plastic.

### Claim 9 (depends on 7)

The disposable dental waste filter device of claim 7 further comprising a flap in the body to prevent any captured amalgam from escaping from within the body.

### Claim 10 (depends on 9)

The disposable dental waste filter device of claim 9 wherein the flap may be moved into a closed position or an opened position.

### Claim 11 (depends on 7)

The disposable dental waste filter device of claim 7 wherein the wherein the flap may be moved into a closed position or an opened position.

### Claim 12 (depends on 7)

The disposable dental waste filter device of claim 7 further comprising a second filter positioned within the body for preventing amalgam that enters into the body from escaping through the receiving end.
