Abstract
The present invention relates to a toothbrush having a handle formed of interlocking opposed S-curved sections, the first being relatively rigid and the second relatively resiliently flexible, the opposed S-curved sections forming a generally elongated figure 8, having an aperture within each segment of the figure 8, such that during brushing the user can manipulate the relatively rigid and resiliently flexible section to position the bristle bearing face of the toothbrush to conform to the arcuate configuration of the dentiture.
Claims24
A toothbrush having a user manipulatable head comprising:
- an elongated handle having a longitudinal axis, an upper side and a lower side;
- which handle is comprised of a first relatively rigid, generally S-curved backbone section and an opposed second and resiliently flexible generally S-curved section;
- the first generally S-curved section extending at one end into a base and at the other end extending into a neck portion provided with a flattened head portion having an upper face containing a plurality of bristle tufts extended therefrom;
- the opposed S-curve sections defining an elongated figure 8, having therethrough an upper aperture and a lower aperture.
A toothbrush having a user manipulatable head comprising:
- an elongated handle having a longitudinal axis and an upper side and a lower side which handle contains a relatively rigid backbone section which defines a first side of an aperture and opposed thereto a resiliently flexible elastomeric section which defines the second side of said aperture, the aperture having a longitudinal axis generally parallel to the longitudinal axis of the handle, the relatively rigid backbone section extending at one end into a base and at the other end extending into a neck portion provided with a flattened head portion with an upper face having extended therefrom a plurality of bristle tufts.
A toothbrush having a user manipulatable head comprising:
- an elongated handle having a longitudinal axis and an upper side and a lower side in which said handle is comprised of a first relatively rigid, generally S-curved backbone section and an opposed second and relatively resiliently flexible generally S-curved section;
- the first generally S-curved section extending at one end into a base and at the other end extending into a neck portion provided with a flattened head portion with an upper face having extended therefrom a plurality of bristle tufts;
- the opposed S-curved sections defining an elongated figure 8 with an upper and lower segment, wherein one segment contains a single aperture and the other contains a plurality of apertures.
A toothbrush having a user manipulatable head comprising:
- an elongated handle having a longitudinal axis and an upper side and a lower side which handle is comprised of a first relatively rigid, generally S-curved backbone section and an opposed second and relatively resiliently flexible generally S-curved section;
- the first generally S-curved section extending at one end into a base and at the other end extending into a neck portion provided with a flattened head portion with a top face having extended therefrom a plurality of bristle tufts;
- the opposed S-curved sections defining an elongated figure 8 with an upper and lower segment, wherein each segment contains a plurality of apertures.
A method of positioning a toothbrush head comprising:
- molding a toothbrush with an elongated handle having a longitudinal axis, an upper and a lower side, which handle is comprised of a first relatively rigid, generally S-curved backbone section and an opposed second and resiliently flexible generally S-curved section;
- the first generally S-curved section having a lower end extending into a base and an upper end extending into a neck portion provided with a flattened head portion having an upper face containing a plurality of bristle tufts extended therefrom;
- the opposed S-curve sections defining an elongated figure 8, having therethrough an upper aperture and a lower aperture;
- positioning the head of the toothbrush by applying pressure to the first relatively rigid S-curved section about the upper aperture, while simultaneously compressing the there-opposed second relatively resiliently flexible S-curved section.
