Abstract: 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.

Abstract: An electrically operated assembly includes a handle housing and a connector for repeatably attaching and detaching a head to and from the assembly. The connector is in direct proximity to a motor having an eccentric weight. The connector is made from a material having an e-modulus that is higher than an e-modulus of the material from which the handle housing is made. A ratio of an overall length extension of the handle housing extending along a longitudinal housing axis to an overall length extension of the connector extending along a longitudinal connector axis is from about 2.5 to about 4.5, and preferably from about 3.0 to about 3.5.

Abstract: A connector-housing assembly for an electrically operated personal-care implement comprises a housing defining an inner cavity and a connector for repeatably attaching and detaching a head to and from the assembly. The connector has an overall length extension (Lc) extending along a longitudinal connector axis (Xc), the overall length extension (Lc) being composed of a sub-length (Li) extending within the inner cavity of the housing, and a sub-length (Lo) extending outside of the housing, wherein a ratio (Rc) of the length (Li) extending within the inner cavity of the housing to the length (Lo) extending outside of the housing is from about 1.0 to 1.7, preferably from about 1.0 to about 1.5.

Abstract: An electrically operated assembly comprises a handle housing defining an inner cavity, a connector for repeatably attaching and detaching a head to and from the assembly, and a motor for operating the assembly, wherein the connector comprises a recess in which the motor is accommodated, and the connector is at least partially made from a material having an e-modulus being higher than the e-modulus of the material from which the handle housing is made.

Abstract: A handle for an electrically operated personal-care implement includes a housing having a proximal end and a distal end opposite the proximal end, and an inner cavity. A connector for repeatably attaching and detaching a head to and from the handle is partially accommodated within the inner cavity at the proximal end thereof. A motor, located in the housing's inner cavity, has an eccentric weight. The connector includes a recess accommodating the motor with the eccentric weight.

Abstract: 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.
