DESCRIPTION

  The present invention relates to the field of oral hygiene by

  Traditionally, the brushing is done using a toothbrush with a brush provided with bristles and manipulated by hand with a handle. The unsightly appearance of this manual method requires his

  user to isolate himself by discretion.From this comes a lack of oral hygiene.

  because of the difficulty of isolating oneself after each meal, in the context of

of everyday life.

  The device according to the invention makes it possible to remedy this drawback by

  preserving the discretion of use.

  The device consists of a support having an H-shaped profile whose all internal surfaces between the vertical branches are lined with bristles.The device has no handle and leaves the hands free.Il is used by positioning between the teeth, and practicing a chewing movement, mouth closed.The bristle trim ensures the simultaneous brushing of the opposing lower and upper teeth, on their three sides, posterior anterior and trituration table.To ensure the

  brushing of all the teeth, the device can be moved laterally

  -into the inside of the oral cavity, closed mouth, acting on him to

  using the tongue, since it is released between two successive chewings

  For this purpose, the device comprises on its rear side a direction

  -Gée inwardly of the oral cavity, a rounded projecting portion allowing the tongue to rely on it to exert the lateral displacement force.The dimensions of the device and its flexibility easily allow the

  brushing two consecutive teeth and their interdental space.

  -mensions of the device are related to human oral morphology.

  The device may be made of flexible plastic material, preferably

  in a single injection molding operation, or by inclusion or

  gluing the bristles on the profiled plastic support.

  The use of the device is disposable, disposable type.

  According to a first variant, the device may have its anterior faces

  and posterior cut vertically, giving them a leaf-like appearance

  -alleles, for greater adaptability to the shape of each tooth.

  According to a second variant, the device may be of circular appearance having an H-shaped profile. According to a third variant, the circular device may have its faces.

  anterior and posterior notched radially.

  According to a fourth variant, the device may be coated with a thin plastic film 2 ensuring the sealing of the cavities containing the bristles,

  to house a hygiene or comfort product, such as toothpaste, sanitizer

  -sant or deodorant, in pasty or liquid form, harmless or drinkable. In order to avoid being swallowed by the user, this film is secured to the device, by gluing, heat-sealing or otherwise, and will be perforated during the first mastication.This film, by its material or structure, must be slightly retractile so as not to clog the cavities containing the bristles. FIG. 1 represents the device according to the invention, presenting the face

later.

  Figure 2 shows the device according to the invention, seen in section.

  Figure 3 shows the first variant of the device.

  Figure 4 shows the third variant of the device.

  Figure 5 shows the third variant of the device-seen in section.

  Figure 6 shows the fourth variant of the device seen in section.

  Figure 7 shows the fifth variant of the device seen in section.

  The device according to the invention shown in Figure 2, consists of a support (1) of flexible plastic material, having an H-shaped profile provided with bristles (2) distributed over all its inner surfaces.The posterior face of the device has a rounded projection portion (3). When the device is positioned between the teeth for use, the bristles (2) enclose the

  opposite teeth and provide simultaneous brushing on all three faces,

  -That chewing.To move the device laterally, the tongue takes

  bearing on the projection (3) and exerts the force in the direction of the desired movement.

  In the embodiment according to Figure 3, the front and rear faces

  -teriors are cut by cuts (4) parallel and vertical.

  In the embodiment according to Figures 4 and 5,1e support (1) is circular in shape and the rounded projection (3); the notches (4) are radial.

  In the embodiment according to FIG. 6, the device is coated by the pel-

  retractile sealing film (5) making the cavities lined with bristles (2)

  able to contain a product of dental hygiene or oral comfort.

  In the embodiment according to FIG. 7, this device is housed in a cap-

protective block (6).

  The device according to the invention is particularly intended for brushing

  for people taking meals out of their homes for reasons of

  -sos professional, school, university, travel, festivities, etc ...
