Definitions
- the present invention relates to a brush with a heel for polishing teeth.
- Brushes which comprise a means for polishing the teeth are known in the art.
- WO 98/22000 (Asher) which discloses a brush comprising rubber massaging bristles in which are embedded an abrasive material .
- WO 96/23431 discloses a brush with tufts comprising particles of a polishing agent.
- US 5 273 425 (Hoagland) describes a pet toothbrush which comprises a tooth surface cleaning means comprising an abrasive structure comprising fibres coated by a non- oxic resinous compound with mineral particles embedded therein.
- Unilever describes a brush comprising movable elastomeric regions flanking a central skeleton.
- the central skeleton preferably a hard plastic material such as polypropylene, provides the distal region of the head.
- the present invention provides a toothbrush comprising a handle and a head with bristles upstanding _
- the heel may be located on the handle, e.g. at the end or at least a suitable distance away from the head, or at the end of the head distal to the handle .
- the heel For the heel to have a suitable polishing effect it must be shaped so as to allow easy rubbing over the teeth. For example, it should not be so large as to proscribe polishing even the easily accessible incisors without great discomfort. A suitable shape would allow the user to polish the incisors even when these teeth do not together provide an even surface, for example, if the teeth are crooked.
- the polishing heel be comprised of a material different to the remainder of the brush it is necessary for it to be capable of providing a polishing effect. Accordingly it is preferred that the heel is comprised of a rubbery material which is unlikely to damage the teeth during use and is unlikely to cause the user discomfort during regular brushing.
- the heel comprises a rubbery material which is preferably a thermoplastic elastomer such as TPE.
- Elastomers suitable in the present invention include any of the elastomers common the art . Such elastomers are disclosed in WO 97/20484 (Unilever) and our co-pending application PCT/EP97/05136 the contents of which are incorporated by reference.
- the heel may comprise a purchasing means . Such a purchasing means could be one or more ridges which help to polish the teeth by increasing the friction between the heel and the tooth surface. The purchasing means may also be m the form of a micro-contoured surface.
- the heel may comprise a polishing material.
- polishing materials include abrasives such as those commonly available m the art, e.g. silica.
- the heel is replaceable when either worn out or to enable another heel with a different shape to be used.
- a replacement heel may be attached to the brush by way of a complementary attaching means provided on the brush.
- An example would be a click-fit between a heel replacement part comprising a male portion and a complementary female portion provided on the brush head or handle.
- a preferred embodiment would provide a slideably engaging means on both the brush head or handle and the replacement part allowing easy replacement fitting.
- the brush according to the invention may be made by conventional techniques, for example, by injection moulding.
- the heel section comprises a material different to the material forming the bulk of the head or handle it is envisaged that the heel may also be made by injection moulding techniques.
- the heel section comprises a material other than the material forming a majority of the brush and where the material of the heel is also used in another portion of the brush that the heel and said other region be linked so as to enable a single injection point be used to make both heel and said other region m one step.
- Such a link may be visible or hidden within the main body of the brush head or handle.
- a heel portion for a brush which is capable of polishing the teeth. It is envisaged that differently shaped heel portions may be used for different purposes and that a user may wish to swap between one heel and another to achieve different aims. For example, a narrow-faced heel may be useful in cleaning the lower incisors where the teeth are crooked and would prevent a wide-faced heel from polishing the entire surface of the tooth. A broader- faced heel may be more useful for the upper incisors where a larger and generally flatter surface is more often presented.
- the brush may comprise more than one polishing heel .
- Each may provide different polishing capabilities .
- the heel is located on the handle it is preferred that it is located on the end of the handle distal to the head to allow for easy use. However, it is also possible that the heel be located within a cavity m the handle and is revealed on removal of a cover which itself provides the distal portion of the handle. The heel may then be present on either of the two portions. While the material of the heel is preferably a soft material it is also possible that it is made from a material of similar hardness to the rest of the brush. For example, both the head and the heel may be made of polypropylene. In such an embodiment the heel will preferably comprise an element which provides a polishing capability, e.g. it has an abrasive embedded therein or it comprises purchasing means.
- Fig. 1 is a perspective view of a brush according to the invention.
- the figure shows a brush (1) comprising a handle (2) and a head (3) with upstanding bristles (4) .
