A replacement toothbrush head assembly is provided for an electric toothbrush. The replacement toothbrush head assembly is provided in the form of an assembly that includes a head portion and a stem portion, such that the head portion may be selectively and easily attached and detached from the stem portion. The head includes a plurality of bristles extending from a main body having a coupling portion. The stem includes a corresponding locking portion configured to receive the coupling portion, such that the head is releasably coupled to the stem in an assembled condition.

A brush product, in particular a toothbrush, having a base body with a head part with a front and a rear side, which includes a bristle carrier with a longitudinal axis and a transverse axis and a bristle field protruding therefrom, wherein the bristle field is formed by at least one group of cleaning elements; a handle part; and a neck part connecting the head part and the handle part; wherein the bristle carrier is provided with bristles which are mounted without being anchored and wherein the bristle carrier includes substantially a central support area, an upper support area, a lower support area, a right support area and a left support area, in which the groups of cleaning elements are arranged. Also, a corresponding method and tool.

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.

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 mould system for producing a tufted body having a curved outer surface, for example one hemispherical half of a spherical toothbrush head, the mould system comprising a mould form having a receptacle and an annular flange circumscribing an open end of the receptacle and at least one slot formed substantially radially in the flange and extending into a sidewall of the receptacle.

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.

An oral care implement with a soft tissue cleaner. The oral care implement may include a handle and a head, the head having a first surface, and an opposite second surface, and a peripheral surface extending between the first and second surfaces. A soft tissue cleaner may have a first cleaner fixed to the second surface of the head and a second cleaner fixed to the peripheral surface of the head. Furthermore, the second cleaner may incorporate a plurality of grooves extending at least a portion of the distance from the first surface to the second surface along the peripheral surface.

The invention relates to an oral care instrument, in particular a toothbrush or a tongue cleaner, including at least one cleaning element made from a first plastic component, wherein the first plastic component contains a thermoplastic elastomer and activated carbon. The invention also relates to a method for producing an oral care instrument, in particular a toothbrush or a tongue cleaner, including the following steps: a) providing a first plastic component by adding activated carbon to a thermoplastic elastomer, and b) producing a cleaning element from the first plastic component using an injection molding method.

A method for manufacturing an oral care implement comprising a handle, a connector, and a head repeatedly attachable to and detachable from the handle via the connector. The method includes the steps of injection molding of at least a part of the handle having a distal end and a proximal end opposite thereto and comprising a hollow portion; injection molding of at least a part of the connector having an outer lateral surface and a recess therein, the recess forming a cavity within the connector; injection molding of at least a part of the head; inserting the connector into the hollow portion of the handle and fixing the connector therein by gluing, welding, and/or press-fitting.

A method for manufacturing a toothbrush having a bristle carrier made of a thermoplastic material with a front side and a rear side is provided. At least one recess formed as a blind hole in the bristle carrier extends from the front side in the bristle carrier, and holds at least one bristle. The at least one bristle is received in a receiving opening of a tool melted to form a thickening at its attachment-side end and inserted with its attachment-side end into the recess. The thermoplastic material is heated and, by pressing the tool against the front side of the bristle carrier, is deformed such that the thermoplastic material is displaced radially inwards into the recess, at least in the region of an edge surrounding the recess, for the form-fitting sealing of the thickening, in that a projection provided radially adjacent to the recess is pressed into the thermoplastic material.
