Definitions

  • the present invention falls within the scope of the provision of instruments for oral hygiene.
  • the present invention relates to a toothbrush which can be used for preventing the formation of dental plaque and tartar.
  • the toothbrush according to the invention allows a more accurate cleaning of the inner side of the lower dental arch as compared to the known solutions from the prior art.
  • dental plaque and the problem of tartar affect most people, regardless of their age. It is known that dental plaque and tartar are mainly deposited at the inner side of the lower dental arch. This phenomenon is due to the presence of several saliva glands in this region, whereby a certain amount of saliva is created and stagnates there.
  • Patent Application EP0957709 A partial solution to the problem mentioned was proposed in Patent Application EP0957709 to the same Applicant.
  • a toothbrush comprising a handle and a supporting head for the cleaning bristles.
  • a recessed portion which extends from the supporting head toward the free end of the handle is defined on one of the handle sides. The presence of such a recessed portion in fact makes the toothbrush effective for cleaning the front and left-hand portions of the inner side of the lower dental arch.
  • the main object of the present invention to provide a toothbrush which allows to overcome the drawbacks mentioned above.
  • the present invention relates to a toothbrush adapted to prevent the formation of dental plaque and tartar.
  • the toothbrush according to the invention comprises a supporting area for bristles for cleaning teeth. Such a supporting area is connected to a handle which extends along a longitudinal axis. Such a handle comprises a first side and a second side, which are opposite to each other. A first recessed portion which extends from the supporting area is defined on the first side.
  • the toothbrush is characterised in that a second recessed portion configured to allow the positioning of the head of the toothbrush at the right-hand portion of the inner side of the lower dental arch is defined on the second side of the handle.
  • the two recessed portions which are defined on opposite sides of the toothbrush handle, advantageously allow the complete and accurate cleaning of the whole lower dental arch, thus overcoming any limitations of known toothbrushes.
  • toothbrush 1 comprises a supporting area 4, hereinafter also referred to as "head 4", which carries bristles 5 by means of which the teeth are cleaned.
  • head 4 defines a substantially flat surface 3 from which the bristles 5 emerge according to an orientation direction 201 which is substantially orthogonal to the surface itself.
  • Toothbrush 1 further comprises a handle 2 which defines a rectilinear longitudinal extension axis 101.
  • Handle 2 is connected to said head 4 while extending therefrom up to a free end 8.
  • Handle 2 has a first side 2' and a second side 2", which are opposite to each other.
  • the first side 2' and the second side 2" are meant as the sides of handle 2 which extend substantially on surfaces parallel to the orientation direction 201 of the bristles 5 indicated above, and preferably substantially parallel to the longitudinal axis 101.
  • a first recessed portion 10 of handle 2 which extends from the supporting area 4 toward the free end 8 of handle 2 is defined on the first side 2'.
  • Toothbrush 1 is characterised in that it comprises a second recessed portion 20 of handle 2 defined on the second side 2" of handle 2.
  • this second recessed portion 20 allows the insertion and correct orientation of the head 4 of toothbrush 1 at the right-hand portion of the inner side of the lower dental arch.
  • a toothbrush is provided through this second recessed portion 20 which finally allows a user to obtain a complete and accurate cleaning of the inner side of the lower dental arch.
  • the presence of this second recessed portion puts the user in the condition of carrying out such a cleaning in accordance with the dental prevention guidelines indicated above.
  • the second portion 20 is longitudinally staggered with respect to the first portion 10. This means that the projection H1 of the second portion 20 along a reference line 200, which is parallel to the longitudinal axis 101, does not overlap the projection H2 of the first portion 10 along the same reference line 200.
  • the second portion 20 is instead only partially staggered in longitudinal direction with respect to the first portion.
  • this instead means that the projection H1 of the second portion 20 along a reference line 200 which is parallel to the longitudinal axis 101, does partially overlap the projection H2 of the first portion 10 along the same reference line 200.
  • head 4 comprises a first longitudinal side 4' and a second longitudinal side 4", which are opposite and parallel to each other.
  • Such sides 4', 4" are "longitudinal' because they are parallel to the longitudinal extension direction 101 of handle 2.
  • the first side 4' is aligned with a rectilinear portion 11 of the first side 2' of handle 2.
  • a rectilinear portion 11 is preferably defined between said first recessed portion 10 and the end 8 of handle 2.
  • the first side 4' of head 2 is misaligned with respect to the first side 2' of handle 2.
  • head 2 has a width (indicated with L1) which is greater than the width (indicated with L2) of handle 2.
  • widths (L1, L2) are measured along a direction which is substantially orthogonal to the longitudinal direction 101.
  • the first recessed portion 10 extends over a longitudinal section (indicated with T1 in Figure 1 ) of 2 or 3 cm, measured between head 4 and the rectilinear portion 11 of the first side 2' of the handle 2.
  • the second portion 20 is in any case always defined between a first rectilinear section Z1 and a second rectilinear section Z2 of the second side 2" of handle 2.
  • the first rectilinear section Z1 and the second rectilinear section Z2 are coplanar and therefore aligned along the same direction parallel to the longitudinal axis 101.
  • Such a second portion 20 extends over a longitudinal section having an extension between 5 and 20 mm.
  • extension of the longitudinal section of the second portion 20 means precisely the measurement of projection H1 along a reference line 200 which is parallel to the longitudinal axis 101 (as already indicated above). It is noted again from Figures 1 and 2 that in both the embodiments shown, the second longitudinal side 4" of head 4 is aligned with the two sections Z1, Z2 of the second side 2" of handle 2.
  • the second recessed portion 20 has a substantially concave profile with an inflection point "P" defined in a position which is proximal to the longitudinal extension axis 101 of said handle 2.
  • the profile of the second portion 20 may take various shapes.
  • the second portion 20 has a middle part 20' and two arc-of-circle side parts 20" which are opposite to each other. Each side part 20" extends from said middle part 20' to a corresponding rectilinear section Z1, Z2 of the second side 2' of handle 2.
  • the second portion 20 is defined by two portions 20', 20" having a different curvature, which are joined close to the inflection point P.
  • the shape of the second portion 20 is variable in shape, it should be such as to allow the positioning and correct movement of the toothbrush at the right-hand portion of the inner side of the lower dental arch.
  • recessed portion (10 or 20) generally means a portion of handle 2 which is substantially concave, i.e. shaped so as to be “recessed” toward the longitudinal axis 101 with respect to a corresponding side 2', 2" of handle 2.
  • head 4 and handle 2 are integrally defined in a single piece and preferably comprise reinforcing fibres, at least as regards the region of handle 2. Such fibres are used to provide a mechanical reinforcement in the handle region between the two recessed portions 10,20.
  • the toothbrush shown in the drawings is intended for a right-handed person. Obviously, for a left-handed person, the toothbrush will thus have a mirroring shape to that shown in the figures while however maintaining the peculiarities described above.
  • the embodiments implemented for the toothbrush according to the invention allow the preset task and objects to be wholly met.
  • the toothbrush allows to prevent the formation of plaque and tartar on both dental arches and in particular along the entire extension of the inner side of the lower dental arch.
  • the toothbrush according to the invention is perfectly usable for cleaning all dental surfaces.
