Definitions

  • the present invention refers to a new toothbrush that restricts the contact of the peripheral bristles, and particularly that of the median bristles with the mucous of the gums. There is thus obtained a maximum reduction of irritation of the gums as well as of wear of the dentine when the same is uncovered.
  • the toothbrushes that are sold in the market worldwide usually have 3 or 4 rows of bristles with an average height of 10 mm. Some have the peripheral bristles thinner than the median rows, these latter being stronger.
  • the purpose of this principle is to prevent the gums to suffer with the contact of the more aggressive median bristles.
  • the pressure applied by the user makes the peripheral bristles bend, thereby brashing and pushing the gums and uncovering the dentine.
  • the present invention provides therefore a toothbrush comprising a head part, a neck part and a handle part, characterized by the fact of the head, which forms an angle of about 170° relative to the handle by means of a neck part with elongate sinusoid shape, being provided with a peripheral row made of thick tufts with 3 mm diameter, wherein the bristles are very thin and have a height in the range of 5 mm to 7 mm.
  • the head of the toothbrush of the present invention having a length of 34 mm and a width of 13 to 15 mm, is also provided with one single median row comprised of small plastic bodies intended to attack the bacterial plaque.
  • those plastic bodies have preferentially a parallelepiped shape, with a square base of 3 mm by 3 mm and a height within the range from 4.5 to 6.5 mm.
  • Each of those plastic bodies has at the top thereof 3 transversal platelets with 0.6 mm of thickness, the central platelet being separated from the other two by a groove with 0.6 mm of width and 2 mm of depth.
  • Each of those platelets is serrated with six triangle-shaped teeth, with 0.5 mm at the base and 0.5 mm in height. That type of "bristles" of the median row shall simultaneously evidence a good degree of aggressiveness and an adequate rigidity capable of preventing, with any slight inclination of the toothbrush, the thin and short peripheral bristles from bending thereby irritating the gum.
  • This type of minute-sized blocks may be substituted by tufts comprised by bristles adequate for their purpose and also having a diameter of 3 mm and a height of 4.5 to 6.5 mm.
  • the median row must adopt that substitution, due to the extremely difficult miniaturization of the minute-sized plastic blocks and the indispensable correct choice of the peripheral and median bristles, having in view the delicate mucous and teeth of children. All the dimensions of such children's toothbrush shall have to be carefully studied in practice.
  • This toothbrush is characterized, finally, by being provided with a "neck” having an elongate sinusoid shape attaching the handle to the head, the purpose thereof being to offset the said head 5 mm upwards mamtaining the same at the angle of about 170° relative to the handle. This position facilitates the contact of the bristles and the minute-sized blocks upon the teeth.
  • Figure 1 shows a side view of an embodiment of a toothbrush according to the invention, the total length of the toothbrush being 18 cm, the handle width being 8 mm and the thickness being 5 mm.
  • Figure 2 is a detailed front view of the head itself of the toothbrush, having a length of 34 mm by a width of 13 to 15 mm and a thickness of 5 mm, wherein are implanted the sixteen tufts of bristles of the median row, provided at both ends thereof with the addition of a protecting tuft identical to the peripheral tufts.
  • the median row of six minute-sized blocks, provided at each end thereof with a protective tuft identical to the peripheral tufts, is sHghtly offset relatively to the two peripheral rows due to its quincunx position.
  • the spaces between the lateral tufts and between tufts and between minute-sized blocks are of 1 mm, except for the tufts located at the two ends of the median row.
  • Figure 3 shows a perspective view of the minute-sized plastic blocks used in the toothbrush according to the present invention.
  • Figure 4 is a side sectional view of a set of coarse bristles that may substitute the minute-sized plastic blocks shown in Figure 3.
  • the head 2 is provided with a peripheral row of sixteen tufts 5 - seven of these on each side and one at each of the two ends - these tufts being comprised of very thin bristles with a diameter of 3 mm and a height in the range between 5 mm and 7 mm.
  • the head 2 is also provided with one single median row of plastic blocks 6 of minute size, which are shown in detail in Figure 3, that may be substituted by tufts of coarse bristles 7, shown in Figure 4.
  • the minute-sized plastic blocks 6 have parallelepiped shape with a square base and have at the top thereof three transversal platelets, wherein the central platelet has a thickness of 0.6 mm and is separated from the other two side platelets, also with 0.6 mm in thickness, by a groove with 0.6 mm in width and 2 mm in depth.
  • the upper edge of each platelet is serrated with six teeth of triangular shape with 0.5 mm at the base and 0.5 mm in height.
  • Such minute-sized blocks may be substituted by tufts of coarse bristles 7, shown in Figure 4, with a diameter of 3 mm. Both the minute-sized plastic blocks 6 and the tufts of coarse bristles 7 have a maximum height in the range between 4 and 6.5 mm.

Abstract

La présente invention concerne une nouvelle brosse à dents réduisant au minimum le contact de la gencive avec les poils périphériques et, principalement, avec les poils médians, évitant le déplacement des gencives et l'usure imposée sur la dentine se trouvant ainsi sans protection. Cette brosse à dents comprend une tête (2), un cou (3) et un manche (4). La tête (2) est pouvue d'une rangée périphérique de touffes épaisses (5) formées de poils très fins d'une hauteur allant de 5 mm à 7mm, et d'une seule rangée médiane (6) comprenant des petits blocs plastiques pourvus de plaquettes dentelées ou de touffes épaisses (7) de poils rigides et agressifs, la hauteur maximale des blocs de petite taille ou des touffes de substitution mentionnées ci-dessus variant de 4,5 à 6,5 mm. Le rattachement du manche (4) à la tête (2) est assuré par le cou (3) de forme sinusoïdale, décalant la tête (2) vers le haut de 5mm, et maintenant celle-ci à un angle d'environ 170° par rapport au manche (4).
