Abstract: An oral care device having a handle, a neck, and a pair of curved arms. The handle includes an enlarged distal end and a reduced proximal end, and a pair of downwardly-extending handle walls. The handle walls are spaced at their upper ends and converge with and join one another at their lower ends to define a substantially V-shaped cross-section and an upwardly-opening blind cavity. A neck extends distally from the handle and defines a tongue portion that is recessed relative to a top surface. A pair of curved arms extend distally and downwardly from the neck. When substantially identical oral care devices are stacked one upon the other, the upwardly-opening blind cavity of one oral care device nestingly receives the downwardly-extending handle walls of another oral care device.

Abstract: A dental hygiene device such as an interdental brush includes a handle, a brush head having bristles extending therefrom, and a neck portion extending between the brush head and the handle. At least some of the bristles may have a substantially triangular cross section. The neck portion defines a longitudinal axis and has a first bending stiffness when subject to loading in a first direction that is substantially perpendicular to the axis, and a second bending stiffness when subjected to loading in a second direction that is substantially perpendicular to the axis. The first bending stiffness is less than the second bending stiffness such that the dental hygiene device can be reoriented during use to provide a more gentle or a more robust cleaning to interdental spaces.

Abstract: A quick-change tooling system includes a plurality of pickers each configured to pick specific items, and a plurality of magazines each configured to hold a stack of the items. A pick and place machine includes a carriage for moving the pickers between a picking location adjacent the magazine and a placing location. The carriage includes a quick-release clamp assembly that allows pickers for different items to be changed quickly and without the use of tools. The magazines and product support plates upon which items are also configured to be changed without the use of tools.

Abstract: A method of making interdental cleaners includes forming a slug by extruding material in a direction of extrusion to form a first slug portion having a generally rectangular first cross-section and a second slug portion having a tapering second cross-section that extends away from the rectangular first cross-section. The method also includes stamping the slug substantially perpendicular to the direction of extrusion to form a plurality of cleaner blanks. The stamping forms the first slug portions into handle portions of the cleaner blanks, and the second slug portions into shaft portions of the cleaner blanks. The shaft portions include two pairs of converging surfaces that taper toward each other to define a point. The method also includes attaching cleaning members to the ends of the shaft portions.

Abstract: A dental hygiene system in which a single elongated handle having a recess in its distal end receives a plurality of carrying members holding different dental hygiene elements. The carrying members have resilient portions retained in the handle recess by way of either a latching portion in a slot in the handle or by way of a frictional fit in the handle recess. A lever is positioned in the slot in the handle for releasing the carrying members with the latching portion.
