Definitions

  • the invention refers to a single use tooth brush, which have some bristles that may contact a cleaning medium which is kept in one section of the brush.
  • tooth brushes having some sections which form the brush itself and its handle. These sections are joined together by a middle section.
  • a tank containing a cleaning medium is provided in the handle.
  • a pumping subassembly is used for feeding the bristly section of the brush with a cleaning medium.
  • the posterior pipe, the anterior pipe, the tank, the casing of the pumping subassembly and the middle section represents the elements of an essentially continuous structure.

  • An inlet and respectively an outlet valve are assembled in front of the pipes.
  • a breather that separates the environment and the tank is assembled in the casing.
  • tooth brushes mostly when the cleaning medium is of a quantity that allows only a single use, consist in the fact that they have a approximately complicated design, mainly as a result of the use of pumping subassembly with membrane. This requires a special rheology of the cleaning medium so that it may be pumped through the inlet and outlet valves without clogging them.
  • Another disadvantage is that tooth brushes are relatively big in handle area.
  • the technical problem resolved by the invention consists in simplifying the assembly of a tooth brush for one single use, which should be light and clean. These requirements are fulfilled by the tooth brush, according to the invention.
  • the brush is characterized in each designing variant by all that is described in the attached claims.
  • the tooth brush obviates the above mentioned disadvantages, because it has a body with a short anterior port.
  • the tank containing the cleaning medium is designed on this section, on which it has been previously provided a calibrated orifice. This orifice is in contact with the tank which is placed before the bristles and bordered in the back and laterally by an amount if them.
  • a tight piston is provided in the tank and it is continued with a rod that partially goes through a long channel provided in a posterior long section of the body communicating to the outside.

  • the tooth brush conform to another designing variant, consist of a body and an inferior all that delimits the tank where is located the above mentioned piston.
  • There is a long slot provided in the body which is delimited in length by some anterior and posterior arms, closed by some areas of the waif such as: an anterior concave one and a posterior right one.
  • the last one is provided with an elongated slot in the posterior area, through which a push and guiding button of the above mentioned rode gets outside. Its move in one direction is limited by the contact with the posterior arm.
  • the tooth brush conform to another designing variant, consist of a body in whose long posterior area, in the front side, is provided the tank where is located the above mentioned piston.
  • a short channel ended with the calibrated orifice situated in the back side of the above mentioned bristles. It is bordered in the front and in the two sides by a number of these bristles.
  • the channel gets through a middle area and partly through an anterior section of the body.

  • the tooth brush may be especially used when it is designed in one of the above mentioned assembling variants: when it has a push/sliding button provided on the superior or inferior side of the body; when it has a tank that may be got out of its shape. It may be used by handicapped people who can not see and who use their touch. Especial designs of the component parts of the brush, according to the invention, allow the above mentioned situations when we need to use it.
  • the tooth brush has the following advantages, according to the invention:
  • - fig. 7 longitudinal section through a body of a brush, according to the invention differently designed;

Abstract

La présente invention concerne une brosse à dents à usage unique conçue pour équiper des trousses de toilette individuelles, des trousses de voyage, les toilettes publiques de restaurants, d'hôtels, de gares ferroviaires et des wagons-lits. Selon l'invention, la brosse à dents se compose d'un corps (1) pourvu d'une courte section antérieure (b). Le réservoir (c) est disposé sur cette section et contient un milieu de nettoyage (2). Un orifice étalonné (d) est conçu sur cette section et est relié au réservoir (c) à l'intérieur duquel le piston (5) glisse de manière étroite. Il est prolongé par une tige (6) qui traverse partiellement un long canal (j) disposé sur une section postérieure (a) du corps (1). La tige (6) est prolongée par une allonge (4) dotée d'une pointe aiguisée qui pénètre le joint d'étanchéité recouvrant l'orifice (d), lorsque l'on souhaite utiliser la brosse à dents. Ceci se produit lorsque l'on appuie sur un bouton (g).
