Definitions

  • the present invention relates to a toothbrush of the type comprising a grip and a cleaning head having a base provided with bristles.
  • toothbrushes are normally made of a single body in plastic material, shaped in order to have a grip and a cleaning head provided with a plurality of bristles.
  • the grip has a variable length according to the user the toothbrush is intended for and, however, it is long enough so as to allow the cleaning head to deeply penetrate inside the oral cavity. Precisely, toothbrushes for paediatric use will have a shorter grip than that of toothbrushes for adults and also the hardness of bristles will be adapted to suit the final user's needs.
  • electrical toothbrushes comprising a grip, housing thereinside an electrical small engine, which is connected to a rotating cleaning head.
  • This latter is normally made of a circular brush having bristles of predetermined hardness, rotating around an axis, which is substantially aligned with the development direction of the bristles.
  • a toothbrush is known from patent CH 179 403, which comprises a grip and a cleaning head with a base provided with bristles, in which there are two facing appendages extending from the base (3a) and equally provided with bristles (6) having different lengths.
  • Toothbrushes similar to that described in CH 179 403 are also known from documents US 1 771 624 and US 2 244 615.
  • the aim of the present invention is that of eliminating the above drawbacks by providing a toothbrush able to allow an easy teeth cleaning, without requiring continuous wrist movements for modifying the inclination of the bristles with respect to the teeth surface and also able to clean with equal efficiency all the teeth, irrespective of their position inside the oral cavity.
  • a further aim of the present invention is that of devising a toothbrush suitable for use both by adult users and children.
  • a further aim is that of achieving the above results, through a simple, rational and reliable constructive solution.
  • 1 globally indicates the toothbrush according to the present invention, which is preferably made of plastic material or other material suitable for hygienic-sanitary uses.
  • Toothbrush 1 comprises a grip 2, preferably provided with ribs to prevent slipping (not shown), and a cleaning head 3 having a base 3a provided with bristles 4.
  • the cleaning head 3 originally comprises a pair of facing and parallel appendages 5a, 5b, extending with continuity from the base 3a.
  • Each appendage 5a, 5b is situated in a position substantially orthogonal to the base 3a and it is provided with bristles 6.
  • bristles 6 situated on the appendages 5a, 5b have different lengths and they are substantially perpendicular to the bristles 4 on the base 3a of the head 3.
  • bristles 6 of the appendages 5a, 5b have variable lengths along a vertical development direction of the appendages themselves.
  • these bristles have lengths ranging between a maximum dimension (see the bristle indicated with number 6a in figure 2) in correspondence with the base 3a and a minimum dimension (see the bristle indicated with number 6b in figure 2) in correspondence with an outer profile 7 of each appendage.
  • bristles 6 of the appendages 5a, 5b have a variable length also along a longitudinal development direction of the cleaning head 3, at a predetermined distance from the base 3a; in particular, these bristles have variable lengths ranging between a maximum dimension in correspondence with the grip 3 (see bristles 6a) and a minimum dimension (see bristles 6b) at the opposite side of the grip 2.
  • the maximum length of the bristles (bristles 6a) is of about 6 mm, whereas the minimum length (bristles 6b) is of about 5 mm.
  • the length variation of the bristles continuously takes place both along the vertical direction, from base 3a to the outer profile 7, both along the horizontal direction, from the grip 2 to the front part of the cleaning head 3.
  • the intermediate bristle length of the appendages 5a, 5b is preferably of about 5,5 mm.
  • bristles 4 on the base 3a of the head 3 they preferably measure 4 mm.
  • appendages 5a, 5b are preferably made in a single body with the cleaning head 3.
  • the toothbrush is introduced into the oral cavity, taking care that the bristles 4 lay on the upper part of the teeth.
  • bristles 6 of the appendages 5a, 5b lay on the teeth side surface, both inside and outside the dental arch and they thus allow an efficient cleaning especially of the teeth side surface facing the inside of the oral cavity, usually the most difficult to be cleaned.
  • variable length of the bristles on the appendages 5a, 5b guarantees the adhesion of the bristles themselves to the teeth side surface.
  • bristles 6a being longer and situated in correspondence with the grip 2, suitably adhere to the teeth located in the front part of the oral cavity (incisors).
  • bristles 6b being shorter, efficiently adhere to the teeth located in the inner part of the oral cavity (molars).
  • teeth cleaning is performed through simple translatory movement of the toothbrush along the dental arch, without needing to vary the inclination of the cleaning head, as it is instead required by toothbrushes according to the prior art.
  • the invention achieves important advantages.
  • a toothbrush according to the invention allows an easy teeth cleaning, without requiring continuous wrist movements suitable for modifying the inclination of the bristles with respect to the teeth surface.
  • a toothbrush according to the invention differently from the toothbrushes of the prior art, ensures an excellent cleaning of the teeth side surface facing the inside of the oral cavity and it can be advantageously used, with the same great results in terms of cleaning, both for the upper and lower dental arch.
  • the toothbrush according to the invention is able to clean, with equal efficiency, all the teeth, irrespective of their position inside the oral cavity and this is of fundamental importance for its use by differently able subjects, such as e.g. subjects suffering from Down syndrome.
  • the toothbrush according to the present invention can be made from soft and elastic plastics material, so as to allow an efficient and pleasant massage of the gums.
  • a toothbrush according to the present invention is simple and economical to be made and it can be personalised with suitable decorations and colours.
