Abstract

A cleaning device includes a handle having a longitudinal axis and a wiper connected to the handle. The wiper includes a plurality of ridges arranged along the longitudinal axis to form a hollow member. The plurality of ridges have a plurality of contact surfaces for contacting a surface to be cleaned.

First claim

What is claimed is:

1. A cleaning device, comprising:
a handle having a longitudinal axis;
a wiper connected to the handle, wherein the wiper includes a plurality of ridges arranged along the longitudinal axis, the plurality of ridges form a hollow member, and the plurality of ridges have a plurality of contact surfaces for contacting a surface to be cleaned; and
a cleaning cloth at least partially disposed on an external surface of the wiper;
wherein the hollow member has an internal surface configured to receive at least a portion of the cleaning cloth;
wherein at least one contact surface of the plurality of contact surfaces is arranged at the internal surface of the hollow member.

2. The cleaning device of claim 1 , wherein the plurality of ridges are oriented perpendicular to the longitudinal axis.

3. The cleaning device of claim 1 , wherein the plurality of ridges are axially spaced along the longitudinal axis.

4. The cleaning device of claim 1 , wherein a flexible region is arranged at an end of the wiper, the flexible region securing the wiper to the handle.

5. The cleaning device of claim 4 , wherein at least one of the flexible region and the plurality of ridges are configured to flex in a direction perpendicular to the longitudinal axis.

6. The cleaning device of claim 4 , wherein at least one of the flexible region and the plurality of ridges is configured to resiliently elongate along the longitudinal axis and/or to resiliently compress along the longitudinal axis, and any combinations thereof.

7. The cleaning device of claim 1 , wherein at least one contact surface of the plurality of contact surfaces is arranged at each of the plurality of ridges.

8. The cleaning device of claim 7 , wherein the at least one contact surface of the plurality of contact surfaces has a flat face.

9. The cleaning device of claim 1 , further comprising one or more openings on at least one of the plurality of ridges extending between an external surface of the wiper and the internal surface of the hollow member.

10. The cleaning device of claim 1 , wherein a distal end of the wiper is an open end.

11. The cleaning device of claim 10 , wherein the open end is configured to provide access to the at least one contact surface arranged at the internal surface of the hollow member.

12. The cleaning device of claim 11 , wherein at least a portion of the cleaning cloth is received in the open end and is disposed on the at least one contact surface arranged at the internal surface of the hollow member.

13. The cleaning device of claim 1 , wherein the cleaning cloth is made of a material selected from a nonwoven material, cotton, polyester, nylon, microfiber, twisted loop microfiber, and any combinations thereof.

14. The cleaning device of claim 1 , wherein the wiper further comprises one or more features that interact with corresponding features on the cleaning cloth to secure the cleaning cloth to the wiper.

15. The cleaning device of claim 1 , wherein a distal end of the wiper is an open end and the cleaning cloth includes a region extendable into the open end.

16. The cleaning device of claim 1 , wherein the wiper is a unitary molded polymer member.

17. The cleaning device of claim 16 , wherein the unitary molded polymer member comprises a material selected from a silicone, urethane, thermoplastic elastomer (TPE), thermoplastic rubber (TPR), the material having a Shore A durometer hardness of between 20 and 100.

18. A method of cleaning a channel having an area at a remote end, the method comprising:
holding a handle of a cleaning device, the cleaning device having a wiper, the wiper having a plurality of ridges arranged along a longitudinal axis of the handle, the plurality of ridges form a hollow member, a distal end of the wiper having an open end, a cleaning cloth is at least partially disposed on an external surface of the wiper, the hollow member has an internal surface configured to receive at least a portion of the cleaning cloth;
inserting the wiper into the channel until the area at the remote end is received within the open end of the wiper and the area at the remote end is in contact with the cleaning cloth; and
moving the handle to move the wiper to clean the area.

19. The method of claim 18 , wherein at least a portion of the cleaning cloth is received in the open end.

20. The method of claim 18 , wherein moving the handle to move the wiper to clean the area further comprises cleaning the area with an internal surface of the wiper and cleaning the channel with an exterior surface of the wiper.
