An interdental cleaner (10) has a rod-shaped support (11) made of plastic, a handle part (12) connected to the support (11), and a cleaning part (13) which has a sleeve-shaped cover (14) arranged on the support (11). The cover carries radially outwardly protruding cleaning elements (15). Provision is made that the cover consists of a plurality of cover parts, wherein a first cover part (16) consists of a first soft-elastic plastic, and wherein a second cover part (17) consists of a second soft-elastic plastic or of a thermoplastic, wherein the plastics material of the first cover part (16) is different than the plastics material of the second cover part (17). Preferably, the plastics material of the first cover part (16) has a lower Shore hardness than the plastics material of the second cover part (17).

A method of manufacturing a unitary toothbrush head having a base and filaments extending therefrom. The method includes steps of injecting molten plastic material into a mold cavity having a pre-base cavity and a filament cavity extending therefrom; compressing the molten plastic material, once it is essentially filling the pre-base cavity, by impressing a punching tool into the molten plastic material from the rear side of the pre-base cavity being opposite to a side from which the filament cavity extends; and filling the filament cavity with the molten plastic material under the continuous impression of the punching tool.

An application element and an applicator comprising pluralities of said application elements on a molded support is provided for applying a product such as a cosmetic, a medicinal or a care product. At least one application element of the applicator includes a base portion and at least one thin projection. The thin projection includes at least one surface and wherein the at least one outer surface flushes with at least a portion of an outer surface of the base portion.

A method of cleaning a surface includes steps of (1) positioning a brush in contact with the surface; (2) rotating the brush relative to a drum about a second axis; and (3) rotating the drum relative to a bracket, supporting the drum, about a first axis, parallel to the second axis, such that the brush orbitally revolves about the first axis.

[Problem] To provide a base part, an interdental cleaning tool, and a method for manufacturing the interdental cleaning tool, capable of preventing bending of a shaft part when a resin material is filled from an insertion end. [Solution] A base part includes a shaft part (20) and a grip part (30). The base part is used for forming an interdental cleaning tool by filling, inside a metal mold having a shape that forms a filling space around the shaft part (20), a resin material into the filling space with the shaft part (20) clamped by a holding pin. The shaft part (20) includes a first guide groove (24) formed on one side with respect to an axially parallel plane and a second guide groove (26) formed on the other side with respect to the axially parallel plane. The first guide groove (24) and the second guide groove (26) extend in the axial direction from an insertion end (22a) toward a base end and have a shape recessed toward the center of the shaft part (20) from the outer peripheral face of a region other than the first guide groove (24) and the second guide groove (26) in the shaft part (20).

A cleaning device includes a bristle bundle and a handle. The handle has a tubular structure and includes a straight part and a bent part, and the bent part is located at the end of the straight part. The bristle bundle is detachably placed in the tubular structure of the handle, and one end of the bristle bundle extends out of the bent part.
