Patent ID: 7007335

Claim:
A toothbrush of elongate form, comprising, bristles; a distal portion; a proximal portion of a generally flat shape in a plane that is essentially inclined with respect to the longitudinal direction of the brush, and which proximal portion extends between the bristles and the distal portion in the longitudinal direction; and an intermediate portion between the distal and proximal portions, wherein the toothbrush has, on a flat horizontal support, at least one position of stable equilibrium; in any position of stable equilibrium of the toothbrush on the support, the longitudinal direction of the toothbrush is essentially parallel to the support and the bristles lie at a distance from the support and extend toward the support; and for any position in which the toothbrush is supported by a flat horizontal support with the longitudinal direction essentially parallel to the support, the distal and proximal portions constitute the portions of contact of the toothbrush with the flat support and the intermediate portion lying at a distance from the support.
