An oral care implement having a handle, and a head having a main body that is coupled to the handle. The head may include a release component coupled to the main body. The release component may include a water-dissolvable matrix comprising a first polymer having a processing temperature greater than or equal to 150° C. The oral care implement may include a plurality of tooth cleaning elements. A method of forming an oral care implement which includes injection molding a composition comprising a graft polymer onto a head of an oral care implement at a temperature equal to or greater than 130° C. to form a water-dissolvable polymer matrix.

A brush (200) for delivering a glutinous substance (168) to a workpiece (170) from an end-effector (102) is disclosed. The brush (200) comprises a body (202), having a rotational axis (238) and comprising a first channel (208) that comprises an inlet (209) and a first outlet (280). The inlet (209) is coaxial with the rotational axis (238) and the first outlet (280) is offset from the rotational axis (238). The brush (200) also comprises tufts (222), extending from the body (202) and each comprising at least one bristle (220) and a tip (227). The brush (200) further comprises a first tube (210), communicatively coupled with the first outlet (280) of the first channel (208) of the body (202).

The brush head of the toothbrush has filaments that are pointed at one end and led through clearances in the bristle carrier. These filaments have a length of about 10-20 mm. The tips of the pointed filaments produce a height profile other than that of a plane and the ends of the pointed filaments that are remote from the tips are melted.

An oral care implement is described. The oral care implement may include a head extending along a longitudinal axis and having a first surface, a second surface opposite the first surface, and a side surface extending between the first surface and the second surface. A central bristle tuft may from a central portion of the first surface. A plurality of perimetric bristle tufts may from the first surface and arranged to circumferentially surround the central bristle tuft. The perimetric bristle tufts may have distal ends that slope downwardly towards the central bristle tuft. The perimetric bristle tufts may be wedge shaped.

A head for an oral care implement comprises at least one tooth cleaning element of a first type and at least one tooth cleaning element of a second type. The at least one tooth cleaning element of the first type has a length extension along a longitudinal axis being about 1 mm to about 2 mm shorter than the length extension of the at least one tooth cleaning element of the second type along its longitudinal axis. The at least one tooth cleaning element of the first type is a tuft of a first type comprising a plurality of filaments, each filament having a longitudinal axis and a substantially cross-shaped cross-sectional area extending in a plane substantially perpendicular to the longitudinal axis. The cross-shaped cross-sectional area has four projections and four channels, the projections and channels being arranged in an alternating manner. The at least one tuft of the first type has a packing factor within a range from about 40% to about 55%, preferably from about 45% to about 50%.

A multi-surface cleaning brush may include: a head portion, an optional handle, and an optional tail portion. The head portion may include a head and a hemi-spheroid region formed by a first plurality of bristles coupled to the head in which the first plurality of bristles may terminate distally from the head to form a substantially hemi-spheroid shape. The head portion and tail portion may be coupled to opposing ends of the handle. Preferably, the first plurality of bristles may comprise microfiber. Preferably, the brush may also include a radial region formed by a second plurality of bristles which may terminate distally from the head to form a substantially cylindrical shape, and the radial region may be positioned between the hemi-spheroid region and the optional handle. An optional handle may be configured as an ergonomically shaped hand grip so that the user's hand may grip the brush via the handle.

An attachment brush part for an electrical body care brush, in particular an electrical toothbrush, includes brush head with an in particular circular bristle carrier, on which a bristle field with a plurality of bristle bundles each with a plurality of care bristles is arranged.

A toilet brush assembly including a brush, including: a handle assembly including a handle assembly proximal end and a handle assembly distal end; and a brush head that includes a plurality of tufts of bristles disposed on an outer surface of the brush head, a cavity defined by an inner surface of the brush head, and a fastener portion. The toilet brush assembly also includes a base, including a cup for receiving the brush head. The brush head selectively couples to the handle assembly distal end at the fastener portion of the brush head at a handle assembly-brush head connection; and at least one of the base and the brush head define at least one interference feature formed from a surface of the base and that contacts the tufts of bristles when the brush head is in a rest position within the cup.

An apparatus (1) for forming bristle bundles (2) is provided. The apparatus (1) includes at least one bundle pocket (3), intended to receive a bristle bundle (2) to be formed. The bundle pocket (3) has at least one piercing (6) in the side. A displacement device (7) on the apparatus (1) can be introduced into the bundle pocket (3) through this piercing (6) to create a clearance (29) inside a bristle bundle (2) to be formed. The bundle pocket (3) and the bristle bundle (2) located therein are heated by the heating device (4) in the apparatus (1) to fix the shape of the bristle bundle (2) defined by the bundle pocket (3) and the displacement device (7).
