Abstract

The present invention relates to a tooth brush comprising a brush handle, a brush stem, and a brush head which carries on the base face thereof a plurality of bristle tufts rising up in a generally uniform direction, wherein the brush head (3) is formed of a plurality of head sections (31, 32, 33, 34, 35, 36, 37) being resiliently movable relative to each other and each being provided with one or more bristle tufts (40, 42, 43).

Claims

1. A tooth brush comprising

a brush handle,

a brush stem connected to said brush handle, said stem comprising a plurality of substantially parallel sub-stems which are resiliently deflectable relative to said handle,

a brush head having a base face and comprising a plurality of head sections connected to said sub-stems remote from said handle, said head sections comprising a central head section and an annular head section concentrically arranged about said central head section and resiliently movable relative thereto, and

a plurality of substantially parallel bristle tufts extending from said base face, said central head section carrying at least one bristle tuft, said annular head section carrying a plurality of bristle tufts.

2. A tooth brush as in claim 1 wherein said bristle tufts on said annular head section are in a substantially annular array about said central head section.

3. A tooth brush as in claim 1 wherein the annular head section is divided into a pair of relatively movable half rings, each half ring being connected to a respective sub-stem.

4. A tooth brush as in claim 1 wherein said central head section carries bristle tufts in a substantially circular array.

5. A tooth brush as in claim 1 wherein said central head section carries bristle tufts in a substantially oval array.

6. A tooth brush as in claim 1 wherein said central head section carries a central bristle tuft which protrudes above the surrounding bristle tufts.

7. A tooth brush as in claim 1 wherein said central head section carries a plurality of bristle tufts arranged so that these tufts form a central bristle tuft in a tooth gap when the tooth brush is pressed against the teeth.

8. A tooth brush as in claim 1 wherein the head sections each have a rear face opposite the base face of the brush head, said central head section having a greater depth, between said base face and its rear face, than the depth of the annular head section.
