Abstract
The invention concerns a toothbrush (2), elongated in shape, comprising bristles (9), and arranged to have on a horizontal flat support (30) at least a stable equilibrium position wherein the longitudinal direction of the toothbrush is substantially parallel to the support and the bristles (9) extending at some distance from the support and towards the support. Said position(s) of stable equilibrium is/are the only position(s) of stable equilibrium of the toothbrush on the support.
Claims14
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.

A toothbrush of elongate form, comprising,
- bristles;
- a distal portion:
- a proximal portion which is off-center with respect to a central longitudinal axis 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.
