Abstract:
1. A toothbrush head, connected to or connectable to a toothbrush grip handle to define a head-handle length direction with a width direction perpendicular to the longitudinal direction, the head having a width and a central longitudinal axis, comprising a flexible bristle carrier which comprises a pad of an elastic material on which bristles are mounted with their ends embedded in the elastic material and having a base part closest to the toothbrush handle when connected, and a longitudinally opposite tip part, and a support which supports the carrier, the support comprising at least one plastic material rib disposed generally longitudinally, the rib having a width that is narrower than the width of the head; wherein the support supports the carrier at the base part and at the tip part, leaving the carrier unsupported thereby in a region longitudinally between these parts, the carrier being flexible such that under the forces of toothbrushing it can deform so that both its longitudinal and widthways sections become distorted and the at least one rib is capable of resilient bending deformation so that under the forces encountered in toothbrushing the tip part of the carrier can move resiliently to follow an arc in a plane perpendicular to the width direction; and the support can perform resilient twisting deformation about a generally longitudinal twist axis.
