Abstract

A cleaning device is provided that includes a handle and a cleaning implement depending from the handle. The cleaning implement has a wiper including a plurality of ridges and a flexible region. The plurality of ridges provide a plurality of cleaning edges to the wiper and the flexible region secures the wiper to the handle.

Claims (12)

1. A cleaning device for cleaning an article, comprising:

a handle;

a cleaning implement depending from the handle, the cleaning implement comprising a wiper including a plurality of ridges in the form of a hollow member that is resiliently compressible along a longitudinal axis of the handle and has a flexible region at one end for securing the wiper to the handle and an open end at an opposite end, the wiper having an external region including at least one external contact surface and an internal region including at least one internal surface that is accessible via the open end, each of the plurality of ridges being axially spaced along a longitudinal axis of the handle; and

a cleaning cloth removably disposed on the wiper, wherein a first portion of the cleaning cloth covers the at least one external contact surface and a second portion of the cleaning cloth covers the at least one internal surface.

2. The cleaning device of claim 1 , wherein the plurality of ridges define a plurality of cleaning faces/edges on the internal region.

3. The cleaning device of claim 2 , wherein the wiper is flexible and configured so that the plurality of ridges allow the wiper to resiliently flex in directions perpendicular to the longitudinal axis, resiliently elongate in directions along the longitudinal axis, and any combinations thereof.

4. The cleaning device of claim 1 , wherein the wiper is formed as a unitary molded polymer member comprising molded silicone or urethane, the material having a Shore A hardness between 20 and 100.

5. The cleaning device of claim 1 , wherein the cleaning cloth comprises a cleaning material at both the exterior and interior regions.

6. The cleaning device of claim 1 , wherein the cleaning cloth comprises a mesh at the exterior region and a cleaning material at the interior region.

7. The cleaning device of claim 1 , each of the plurality of ridges has a substantially identical configuration.

8. The cleaning device of claim 1 , wherein at least one external surface of each of the plurality of ridges is arranged at an angle relative to the longitudinal axis of the handle.

9. The cleaning device of claim 8 , wherein at least one of the plurality of external surfaces of each of the plurality of ridges is arranged at a positive angle relative to the longitudinal axis of the handle and at least one of the plurality of external surfaces of each of the plurality of ridges is arranged at a negative angle relative to the longitudinal axis of the handle.
