## Abstract

An implement for cleaning ears is shown and described. The implement may include an elongated handle and assembly designed to connect with the elongated handle that serves as a cleaning head. The assembly may have a plastic cone, rubber overmold designed to fit over the plastic cone, and sponge designed to fit over the rubber overmold. The plastic cone can attach to the elongated handle by way of a screw-on threaded connection, prongs that mate with slits on the plastic cone, or a combination of these. The implement may be part of a kit also including a container of containing oil foam having oil, soap, and water; a package containing a supply of liquid permeable pads impregnated with antibacterial liquid; and a spray container containing antibacterial liquid. Optionally, the kit also includes a container containing a supply of liquid permeable pads impregnated with an astringent agent.

## Claims

An implement for cleaning ears, the implement comprising:
an elongated handle terminating at a pair of prongs protruding vertically therefrom, each prong terminating at an engagement member projecting horizontally from the prong at a right angle;
a disk having a threaded side and an aperture designed to receive the pair of prongs; and
cleaning head assembly components comprising:
a plastic cone having a bottom threaded opening designed to screw onto the threaded side of the disk and a pair of bilateral slits designed to receive the pair of prongs;
a rubber overmold over the plastic cone; and
a sponge designed to fit over the rubber overmold.

### Claim 2 (depends on 1)

The implement of claim 1, wherein the plastic cone has a recess designed to entrap the sponge between the plastic cone and the disk.

### Claim 3 (depends on 1)

The implement of claim 1, wherein the rubber overmold is attached to the plastic cone.

### Claim 4 (depends on 1)

### Claim 5

An implement for cleaning ears, the implement comprising:
an elongated handle terminating at a threaded portion protruding vertically therefrom;
a disk having a bottom threaded opening designed to screw onto the threaded portion of the elongated handle and a pair of prongs protruding vertically from the disk, each prong terminating at an engagement member projecting horizontally from the prong at a right angle; and
cleaning head assembly components comprising:
a plastic cone having a bottom aperture and pair of bilateral slits designed to receive the pair of prongs;
a rubber overmold designed to fit over the plastic cone; and
a sponge designed to fit over the rubber overmold.

### Claim 6 (depends on 5)

The implement of claim 5, wherein the plastic cone has a recess designed to entrap the sponge between the plastic cone and the disk.
