A method of forming an oral care implement, a method of forming a head plate for an oral care implement, and an oral care implement or head plate formed therefrom. The head plate may have micro-sized or fine features. The method may include providing an amount of a first solid material upstream of a first mold cavity; prior to the first solid material entering the first mold cavity, applying ultrasonic energy to the first solid material to melt the first solid material into a first molten material; flowing the first molten material into the first mold cavity; allowing the first molten material to harden within the first mold cavity to form a head plate comprising micro-sized features; forming a body from a second material, the body including a handle portion and a head portion; and coupling the head plate to the head portion of the body.

The application device for applying a fluid product to keratin fibres comprises a plurality of spikes, distributed over an elongate core extending along a longitudinal axis X, each spike comprising a first stage extending from an anchoring end anchored in the core towards an intermediate section and a second stage extending from the intermediate section towards a free end, and comprising a joint face parallel to the longitudinal axis X, an intermediate point, the middle of a segment of intersection between the joint face and the intermediate section, included in a first half-disc (D1) of radius R1, a segment of which forming a diametral edge is parallel to the longitudinal axis X and lies on a plane parallel to a radial plane comprising the longitudinal axis X and an apical point, the middle of a segment of intersection of the joint face and a section of the free end, included in a second half-disc (D2) of radius R2, a segment of which forming a diametral edge is parallel to the longitudinal axis X and lies on a plane parallel to the radial plane comprising the longitudinal axis X.

An interdental cleaning tool includes a base portion including a shaft portion having a shape insertable in an interdental space, a top end side cleaning portion including a top end side body covering a top end side portion of the shaft portion, and a plurality of top end side bristles protruding outward from an outer circumferential surface of the top end side body, and a base end side cleaning portion including a base end side body covering a portion of the shaft portion further in a base end side than the top end side body, and a plurality of base end side bristles protruding outward from an outer circumferential surface of the base end side body. The top end side cleaning portion has a lower hardness than the base end side cleaning portion.

An oral care implement (100) having a head (120). The head (120) has a support structure (130) and a monolithic cleaning unit (140) that is coupled to the support structure (130). The head (120) has a side surface (123) that includes a first lateral portion (124) and a second lateral portion (125). The monolithic cleaning unit (140) includes a base portion (141) that is coupled to the support structure (130) and a plurality of bristles (150) extending from the base portion (141). The plurality of bristles (150) include a plurality of first peripheral bristles (171) positioned adjacent to the first lateral portion (124) of the head (120), a plurality of second peripheral bristles (172) positioned adjacent to the second lateral portion (125) of the head (120), and a plurality of central bristles (175). The first and second peripheral bristles (171,172) all extend obliquely from the front surface (121) of the head (120) and the central bristles (175) extend perpendicularly from the front surface (121) of the head (120).

A toothbrush comprised at least one unitary brush head having a base and at least one filament and extending therefrom and having a free end terminating with a tip, wherein the filament has a length of from 6.0 mm to 20.0 mm between the base and the free end, and wherein the unitary brush head is made from a plastic material that has a melt flow rate of not greater than about 30 g/10 min measured in accordance with ISO 1133.

The disclosed subject matter is directed to a hairbrush. The hairbrush comprises a plurality of heating elements protruding from a face of the brush, the heating elements defining a hair treating area. The hairbrush further comprises a plurality of self-adjustable spacers projecting from at least some of the heating elements and configured for axial displacement relative to said at least some heating elements between a projecting position and a retracted position, wherein at the retracted position the at least some spacers are partially retracted into respective heating element maintaining a space between a tip of the heating elements and the scalp, and wherein the spacers are self-adjusting to the contour of a users' scalp.

A dual-sided pacifying gum and teeth cleaning device. The pacifying cleaning device is comprised of a U-shaped cleansing portion proceeding in a circular manner between the base of a nipple and a raised lip displacer. The cleansing portion has a pair of walls with sets of bristles, such that the respective sets of bristles generally face each other. As an infant sucks on the pacifying device, the position of the bristles and sucking action result in frictional contact against both the front and back of the infant's teeth, providing improved overall cleaning of teeth and gums.

A dental polishing cup includes a body that defines a cup cavity for holding a dental treatment material, with the cup having an opening at its distal end. A portion of the body includes an enhanced-flexibility band (EFB) situated circumferentially at a certain distance from the distal end, the EFB providing a lesser stiffness of the body than other portions of the body that are situated lengthwise immediately distally and immediately proximately of the EFB.
