Document Type and Number:
Japanese Patent JP2733586
Kind Code:
B2
Abstract:
The problem of providing a toothbrush with a head (10) which has flexibility relative to the handle (14) is solved by incorporating within the handle (14) a resiliently flexible portion (18) which comprises at least one transverse V-shaped fold (22) formed integrally with the remainder of the handle (14) and in a plane of 30 DEG to 150 DEG to that in which the handle (14) lies. Additional control of the flexibility may be achieved by the incorporation of a longitudinal structural rib (24) across a U-shaped fold (22).
