Abstract
A toothbrush has a handle of plastics material and, at one end thereof, a head, the handle including, as integral parts thereof, a grip portion, a resiliently flexible portion and a head-carrying portion, the resiliently flexible portion comprising at least one transverse V-shaped fold formed integrallly with the remainder of the handle and in a plane at from 30.degree. to 150.degree., preferably substantially at right-angles, to that in which the handle lies, whereby the resiliently flexible portion permits the head-carrying portion, on the application of pressure to the head, to be moved at an angle to the grip portion and out of the plane in which it normally lies, and to revert to its original position on the release of pressure.
Claims16
A toothbrush comprising:
- (a) an elongated handle constituted of synthetic plastic material and extending along a central longitudinal axis between a grip handle portion and a head-carrying handle portion, said grip handle portion having a central longitudinal plane in which the grip handle portion lies in a non-flexed position;
- (b) a head supported by the head-carrying handle portion and having a plurality of bristles on, and projecting from, the head;
- and
- (c) resilient flexible means integral with the handle between the grip handle portion and the head-carrying handle portion for permitting angular joint displacement of the head-carrying handle portion and the head relative to the grip handle portion out of the non-flexed position and in a displacement plane normal to the central longitudinal plane, said resilient flexible means including at least one pair of arm interconnected at a fold that extends along a fold axis parallel to the central longitudinal plane and perpendicular to the displacement plane, said bristles on the head projecting substantially parallel to the displacement plane.
