An oral care implement and/or a cleaning element for an oral care implement. The cleaning element may include an annular cleaning component having an inner surface defining a cavity. The annular cleaning component may be formed from a plurality of arcuate portions with each of the arcuate portions extending from a first end to a second end and terminating in a distal end. A height of each of the arcuate portions may be greater at the second end than at the first end. The plurality of arcuate portions may be arranged in a ring so that the first end of each of the arcuate portions is adjacent to the second end of another one of the arcuate portions.

Cleaning tools and associated methods for cleaning lumens of medical devices are provided. An embodiment of the cleaning tool comprises an elongated core, two scrubbers attached to the elongated core, and a wiper attached to the elongated core. The wiper is axially disposed between the two scrubbers. The cleaning tool may be used to clean the lumen prior to decontamination of the lumen.

Disclosed herein is a disposable, biodegradable toothbrush. The toothbrush may comprise a handle portion and a head portion coupled to the handle portion. The head portion may comprise a surface and a plurality of spaced bristles extending perpendicularly outwards from the surface of the head portion for brushing teeth. The surface of the head portion may have dehydrated dentifrice powder deposited on at least a portion of the surface. The plurality of spaced bristles may comprise a first type of bristles and a second type of bristles. Also disclosed herein is a method of producing any of the disposable, biodegradable toothbrushes described herein.

A toilet brush comprises a handle and a brush head. A backbone core is coupled to the handle. An inner support piece is further coupled to the backbone core and to the brush head. The handle further comprises an attachment area and the brush head further includes a scraping feature.

An oral care implement that dispenses an oral care agent during use and a method of assembling such an oral care implement. The method may include contacting a suction tool to a supporting member and then contacting the supporting member to a dissolvable element to form a sub-assembly. Next, the sub-assembly may be inserted into a cavity of a head portion of an oral care implement. Then, the suction force applied by the suction tool onto the sub-assembly may be released to leave the sub-assembly in the cavity of the head portion. Finally, an oral cleaning member may be coupled to the head portion of the oral care implement.

The present invention is a snow/ice cleaning tool for removing snow or ice or a combination of such from a vehicle windshield for also rotating the wiper arms to a rest position for cleaning and returning the wiper arms to a working position in contact with the windshield. The cleaning tool has an elongated handle having one or more working ends incorporating snow/ice cleaning devices. Connected to the handle and slanting away from the handle axis is a grasping device with an opening therein for grasping the wiper arms. The present invention allows for the user to lift and lower the wiper arms from either side of the vehicle in a manner that is safe and ergonomic, regardless of the direction in which the wiper arms pivot.

The present invention wants to provide an improved tongue cleanser showing an improved cleaning effect. For this, a tongue cleanser is suggested having an essentially disc-shaped body, which is provided on its use-side front surface with a profiling suitable for superficially scraping impurity adherent to the human tongue and which forms a hose connection, which communicates with the profiling.

A toilet brush 1 having an articulated connection 5 between brush head 4 and brush handle 3 has a targeted blocking or lock in one of the two possible pivoting directions of the articulated connection 5 formed as a rotatable joint 10. For this purpose, the rotatable joint 10 is formed by the two fork ends 32, 33 at the end of the brush handle 3 and an axis 11, whereby the fork ends 32, 33 permit pivoting towards the side 15, but lock towards the other side 16, because here the two fork ends 32, 33 are connected to each other via a locking shell 41 and prevent pivoting. This locked, articulated connection 5 permits on the one hand very intensive cleaning of the outlet of the toilet basin, because the brush head 4 is bent up when pushed through and can then also clean the upper area of the outlet pipe. In addition, when the toilet brush 1 is turned, this articulated connection 5 is locked simultaneously and can clean the rest of the toilet basin with the corresponding pressure and also the inner channel at the upper edge of the toilet basin, again with the curved brush head 4. This improved cleaning effect is further optimized by the fact that practically the entire brush head 4 especially with bristles 6, 7, 8 is made of flexible, hygienically flawless material.
