Definitions

  • This invention relates to toothbrushes.
  • the present invention utilises a bristle-bearing head which is pivotable with respect to the handle of the toothbrush. Toothbrushes having pivoting heads are known from US Patents 4,333,199, 5,072,481, 5,228,166, 4,575,894, and International Patent Applications PCT/US94/12696 and PCT/EP94/02070.
  • a toothbrush including : - an elongate handle; a head pivotably mounted relative to the elongate handle about an axis which is substantially orthogonal to the elongate handle, the head including an array of bristles which extend in a direction which is substantially parallel to the pivoting axis; characterised in that the head is mounted for limited rotation relative to the elongate handle between a first position for brushing the left hand side of the teeth and a second position for brushing the right hand side of the teeth.
  • a neutral position for brushing the front teeth is disposed intermediate the first and second positions .
  • retaining means are provided to retain the head at the first and second positions.
  • the retaining means may involve detents, frictional engagement or any other means.
  • Retaining means may also be provided to retain the head at the intermediate neutral position.
  • the elongate handle and pivotably mounted head lie in substantially the same plane with the axis of pivoting being substantially orthogonal to said plane .
  • the head may be removable from the handle so as to be replacable .
  • FIGS 1 to 4 are views of one embodiment of a toothbrush
  • FIGS 5 to 8 are views of a second embodiment of a toothbrush
  • FIGS 9 and 10 are longitudinal and transverse cross- section views of the head, respectively.
  • FIGS 1 to 4 there is illustrated a toothbrush 10 having an elongate handle 12 and a pivotably mounted head 14.
  • the pivotably mounted head 14 includes an array of bristles in the normal manner.
  • the head 14 lies in substantially the same plane as the handle 12 as can be best seen in FIG 1 and is mounted for limited pivoting movement between first and second positions about an axis which is orthogonal to the plane of the handle and head as can be seen from FIGS 2 and 3.
  • the head 14 is shown in the first position in which it is adapted to brush the left hand side of the teeth.
  • the head is shown in its second position in FIG 3 and in the neutral intermediate position in FIG 1. Stops or abutments are provided to prevent rotation beyond the first and second positions.
  • the pivoting is facilitated by a pin 16, although other known pivotal mounting arrangements such as a resilient "snap" mounting or other known means could be used.
  • the head 14 is mounted for limited pivoting relative to the handle 12.
  • retaining means are provided so as to releasably retain the head at the limits of its pivotal range of motion as shown in FIGS 2 and 3.
  • the retaining means takes the form of a radial protrusion on the head 14 and a corresponding recess on the handle 12, although the retaining means could take any form and may simply involve frictional engagment between the handle and head.
  • the handle 12 and head 14 are made of a resilient plastics material and the plastics material must elastically deform during pivoting of the head between its preferred first, neutral and second positions. Referring now to FIG 4, it can be seen that, in use, the toothbrush head is pivoted to one of the first and second positions (depending on whether it is desired to brush the left or right teeth) and inserted into the mouth.
  • FIGS 5 to 8 there is shown a second embodiment in which similar numerals have been used to denote similar features.
  • the difference between the first and second embodiment is simply that the array of bristles has been rotated through 90 degrees so that, in the neutral position shown in FIG 5, the major axis of the array of bristles is parallel to the handle 12 (it will be recalled that in FIGS 1 to 4, the major axis of the array of bristles was orthogonal to the handle 12) .
  • the head is pivoted to the first position and inserted into the mouth in the normal manner (if the toothbrush was to be used on the teeth on the right hand side of the mouth then the head would be pivoted to the opposite limit or second position) .
  • the bristles are presented to the teeth in a manner in which the user is encouraged to brush in an up and down direction.
  • the length of bristles in the array is preferably varied along the major axis of the array to provide a degree of conformity with the profile of the teeth.
  • the length of the bristles in the array may also be varied along the minor axis to protect the gums.
  • a particular advantage of the toothbrush according to this invention is that the array of bristles is naturally moved in a more correct direction to clean the gaps between the teeth.
  • the pivotal mounting of the head of the toothbrush allows the head of the toothbrush to move in a direction more closely parallel to the gaps between the teeth.
  • the toothbrush according to the present invention has been found to more effectively remove plaque at the extremities of the teeth adjacent the gums and improve the health of the gums.

Abstract

La présente invention concerne une brosse à dents (10) comportant un manche (12) et une tête (14) garnie de soies. Cette tête (14) est montée de façon à être capable d'un pivotement limité par rapport à la poignée (12). Des crans servent de butée à la tête en limite de pivotement. La tête (14) et le manche se situent dans le même plan pour limiter l'encombrement de la brosse à dents. Le pivotement de la tête favorise un brossage correct des dents.
