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.

System and method for moulding a tufted body with a curved outer surface

This invention relates to a drive system which automatically disengages when a loading above a certain threshold limit is applied to the driven component, thus preventing damage to the drive system and foremost to the gearing between the drive system and the driven component when such a load is applied.

Handheld device drive system

The present invention is concerned with an electric utility brush having a flexible drive shaft, and in particular an electric toothbrush having a substantially spherical head mounted on the flexible drive shaft and which can be driven rotationally in at least two different orientations in order to provide comprehensive brushing capabilities.

Electric utility brush having a flexible drive shaft

The present invention provides a template for a tufted curved surface such as a hemispherical brush head for an electric toothbrush or the like, the template comprising a substrate having an upper surface adapted to carry one or more tufts of bristles such as to project outwardly from the upper surface, the substrate being shaped to be deformable between an expanded state in which the upper surface is substantially flat, and a collapsed state in which the upper surface is curved.

Template for a tufted curved surface

The present invention provides a drive system having particular utility in an electric toothbrush, the drive system comprising a coupling () which is connectable between a drive source () and a brush head (), the coupling being adapted to impart first and second independent brushing motions to the head.

Drive system

The present invention provides a toothbrush (), in particular a mechanical toothbrush () more commonly known as an electric toothbrush (), which includes a spherical brush head () which is capable of undergoing at least first () and second () independent brushing motions in order to improve the overall brushing effectiveness.
