Abstract
The toothbrush according to the invention is equipped with a handle of which the surface is formed, at least in certain sections, in a facet-like manner by way of multiplicity of planar surface-area elements. The surface-area elements are arranged directly adjacent to one another and form a network of element edges. The multiplicity of surface-area elements reproduce, more or less, an essentially rounded handle form, this ensuring comfortable use of the toothbrush in different rotary positions in relation to its longitudinal axis.
Claims22
A toothbrush with an elongate handle, a neck adjoining the elongate handle on one side and a head arranged on the neck opposite from the elongate handle, a surface of the elongate handle being provided with at least approximately planar surface-area elements, which are respectively arranged adjacent one another and directly adjoin one another to form element edges, wherein
- the elongate handle has at least in certain portions a multiplicity of the at least approximately planar surface-area elements, which are arranged on the surface in a facet-like manner and have a base area with a maximum extent of 0.2 mm to 8 mm, and thereby approximately form an essentially rounded basic form of the elongate handle, and
- the element edges adjoining one another form a contiguous edge line, which wraps spirally around the handle.
A toothbrush with an elongate handle, a neck adjoining the elongate handle on one side and a head arranged on the neck opposite from the elongate handle, a surface of the elongate handle being provided with at least approximately planar surface-area elements, which are respectively arranged adjacent one another and directly adjoin one another to form element edges,
- wherein the elongate handle has at least in certain portions a multiplicity of the at least approximately planar surface-area elements, which are arranged on the surface in a facet-like manner and thereby approximately form an essentially rounded basic form of the elongate handle, wherein,
- at least in the certain portions, sectional lines through surface-area elements run periodically concave-convex in a longitudinal sectional plane in which a longitudinal axis of the elongate handle likewise lies.
A toothbrush with an elongate handle, a neck adjoining the elongate handle on one side and a head arranged on the neck opposite from the elongate handle, a surface of the elongate handle being provided with at least approximately planar surface-area elements, which are respectively arranged adjacent one another and directly adjoin one another to form element edges,
- wherein the elongate handle has at least in certain portions a multiplicity of the at least approximately planar surface-area elements, which are arranged on the surface in a facet-like manner and thereby approximately form an essentially rounded basic form of the handle,
- wherein surface normals of adjacent surface-area elements in a middle handle portion with respect to a longitudinal axis of the elongate handle enclose angles of between 1° and 30° , and surface normals of adjacent surface-area elements in a free end region of the elongate handle enclose angles of between 20° and 50°.
