Definitions
- the present invention relates to a toothbrush provided with a bristle-carrying head mounted on the handle via a hinge which is flexible, i.e. capable of assuming any angle during use.
- Toothbrushes normally comprise a substantially straight handle part which extends into a head part which is also straight and on which the cleaning bristles are mounted. In the most well-known arrangements the head part is aligned with the handle part. This arrangement has been adopted with satisfactory results for very many years, despite the fact that it is not particularly suitable - since it creates a few problems during use - for cleaning the deep-lying zones located behind the molars of the teeth.
- toothbrushes In order to overcome this problem it is known that for some time so called “angular " toothbrushes have been available commercially, said toothbrushes having in fact a head which is bent at an angle with respect to the axes of the handle. This angle - which to a certain extent imitates the shape of a dental mirror - is intended to facilitate cleaning of the convex parts of the teeth and of the zones located behind the molars and the incisors. These toothbrushes, however, are less suitable for cleaning the front part of the teeth and in fact are generally unsuitable for cleaning the concave zones of the teeth.
- Toothbrushes having the handle, or at least a part of the handle, which is able to flex in the direction of its length. Toothbrushes of this type are described for example in DE-C1-39 23 495, DE-C2-42 23 697, DE-C1-42 22 931, DE-GM-89 03 911 and EP-A2-0.371.293. This flexibility, however, is intended - as clearly stated in DE-C1-39 23 495 - to allow the cleaning pressure on the teeth to be controlled more easily so as avoid damaging the latter.
- the flexing or hinging zone is located at a middle point along the handle and in particular in a zone where the thumb of the hand rests during use, i.e. in a zone situated outside the mouth during use of the brush: only in this way, in fact, is the user able to sense exactly how much the brush is flexing and consequently how great the cleaning pressure is.
- the aim of the present invention is to propose a toothbrush which overcomes the drawbacks of all the known brushes mentioned above and which, in particular, via a structure which is simple and economic to manufacture and practical and perfectly hygienic to use, makes it possible to perform cleaning of any part of the teeth, i.e. both the concave and convex front part and internal parts as well as the deeper-lying parts located behind the molars.
- This aim is achieved via the characteristic features indicated in the characterising part of Claim 1.
- said hinge is formed by an assembly of two flexible, thin, side bridge-pieces, made as one piece with the handle and the head and constituting the main element for joining and connecting together the latter, and by a mass of elastomeric filling material injected into the space between said bridge-pieces and constituting the secondary joining element.
- the brush comprises in a known manner a handle 1 and a head 2 on which the bristles 3 are mounted.
- the head 2 and the handle 1 are made of a relatively rigid plastic material and are joined together via a flexible hinge.
- the axis of this hinge is arranged in a plane parallel to the plane of the head on which the bristles are fixed and is oriented perpendicularly with respect to the longitudinal axis of the brush. In this way the head has in practice a variable angle with respect to the handle.
- Such a flexible hinge consists, according to the preferred embodiment shown in the drawings, of an assembly of two moderately flexible, thin, side bridge-pieces 1a - formed as one piece with the handle 1 and the head 2 and constituting the main element for joining and connecting together the latter - and of a mass 4 of elastomeric filling material injected into the space between the bridge-pieces (indicated by a broken line in the drawings).
- the assembly consisting of handle, head and bridge-pieces is made of a relatively rigid plastic material; consequently, the handle and the head are rigid and only the bridge-pieces, owing to their thin cross-section, are flexible. This flexibility is then controlled via the greater or lesser yielding capability of the mass 4 of elastomeric filling material.
- the head 2 of the brush is able to assume different angles I, II, III, with respect to the handle, during use, so as to facilitate cleaning of both the concave surfaces and convex surfaces of the teeth.
- the brush according to the invention is particularly suitable also for cleaning of the deep-lying zones located behind the molars.
- the handle 1 and the head 2, as well as the bridge-pieces 1a are made of a material having a chemical affinity with the material constituting the filling mass 4, such that it is possible to provide a lasting and stable bond between these elements by means of simple two-stage injection moulding, without the addition of any binder.
- a material having a chemical affinity with the material constituting the filling mass 4 such that it is possible to provide a lasting and stable bond between these elements by means of simple two-stage injection moulding, without the addition of any binder.
- polypropylene for the handle part 1, head 2 and bridge-pieces la
- the filling mass 4 will consist of a polyolefin-based elastomeric material.
- suitable materials may readily occur to a person skilled in the art.
- the hardness of the elastomeric material of the mass 4 it will be possible to grade the rigidity of the "hinge" according to the intended use of the brush (soft, medium or hard; for adults or for children).
