A method for manufacturing a brushing part, the brushing part being configured in a U-shape in order to be placed on the dentition of a jaw of a user, the brushing part forming a channel inside which is designed to receive all or a portion of said dentition, the brushing part comprising at least one tuft of brushing bristles projecting into the interior of said channel by a free end of the bristles of the at least one tuft, the method comprising the following steps: —forming the at least one tuft of bristles by assembling a plurality of bristles by an end opposite the free end, so as to form a base of the at least one tuft; —fusing the ends forming the base of the at least one tuft so as to form a fused area in one piece, such that an extension of the fused area in a direction that is transverse to an extension direction of the at least one tuft is greater at one extension of the base in the transverse direction prior to the fusing step; —placing the at least one tuft on a mold for overmolding the channel of the brushing part; —overmolding the channel and the at least one tuft.

An oral care implement used for treatment of a user's oral cavity. The oral care implement may include a body having a longitudinal axis, a first hard plastic component, and a second hard plastic component. The first hard plastic component may have a front surface having a perimeter portion and a central portion that is surrounded by the perimeter portion, the central portion being recessed relative to the perimeter portion. The second hard plastic component may be positioned on the central portion of the first hard plastic component and surrounded by the perimeter portion of the first hard plastic component. The second hard plastic component may have an outer surface with a plurality of grooves that are elongated in a direction of the longitudinal axis.

An oral care implement comprises a head and a handle, the head being repeatedly attachable to and detachable from the handle. The head is made from a non-magnetic and/or non-ferromagnetic material, while the handle is at least partially made from a magnetic and/or ferromagnetic material.

A cleaning element carrier for a toothbrush in a form of a disk has a back surface including a central depression covering at least 70% of the back surface and forming an edge at the border. The carrier's front surface includes at least one protrusion so that the front surface comprises two levels, wherein the area covered by the depression is larger than the area covered by the protrusion.

A brush head (10) and a method (200) for manufacturing a brush head. The method (200) includes stamping (220) a plurality of openings (62) into a strip or roll of backing material (60). A bristle tuft (21) is inserted into each of the openings in the backing material. A proximal end (23) of each bristle tuft is bonded to a proximal side (63) of the backing material to create a merged proximal end head portion (26). Excess portions of the backing material are removed to form a plurality of carrier elements (24) about the openings from the backing material. The carrier elements form a plurality of merged tuft assemblies (20). A platen (42) of a neck (40) is positioned in relation to the merged tuft assemblies. A matrix material (30) is injected around the platen and the merged tuft assemblies to at least partially encompass the platen and the carrier elements of the merged tuft assemblies.

A strip brush assembly with a plurality of elongated polymer bristles forming a section and a plurality of elongated metal bristles forming another section adjacent the polymer bristles section, such that the metal bristles section is supported by the polymer bristles section. The polymer and metal bristles are bonded and encapsulated in a base formed by direct extrusion onto and around the polymer and metal bristles to secure them to the formed base. The strip brush assembly may be used on a tubular mandrel of a street sweeper.

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.

There is disclosed a hair brush. The brush has an elongate body including a utility portion and a handle portion at opposite ends thereof and defining a longitudinal axis. The utility portion includes a back member acting as a support from which brushing protections extend, and defines a first plane and a second plane perpendicularly intersecting the first plane. The back member is flexibly movable with respect to the handle portion on the first plane and the second plane. The utility portion further includes a pair of spines arranged at opposite sides of the back member for controlling the flexible movement of the back member whereby the extent of control of movement of the back member by the spines are either limited to the movement on only the first plane or substantially more on the first plane than the second plane.

A cell of a brush making device for making at least a part of a toothbrush, having a pin unit having at least one pin, a pin holding sub-unit and a pin guiding sub-unit, the pin having a first section having a first end and a second section having a second end, the first section having a holding structure, and at least one spring section arranged between the first section and the second section, the pin holding sub-unit having a holding structure that is engaged with the holding structure of the pin for fixedly holding the pin, the pin holding sub-unit and the pin guiding sub-unit being arranged for being movable along a first direction towards and away from each other, and the pin guiding sub-unit having a channel for guiding at least a portion of the second section of the pin, the channel being inclined against the first direction.
