Abstract

The invention relates to a brush for oral and dental hygiene, incorporating a toothpaste product in a protectively sealed cell in a leaktight manner. It is composed of a handle 1 for gripping, of a tufted head 2 in which a seat 3 is arranged, which has a slide 4 in which is inserted, according to a longitudinal axis, a cell 5 which is protectively sealed by a film and which contains the toothpaste product. The supply of the toothpaste onto the bristles 8 through transfer orifices 9 provided in the head is caused by finger pressure which gives rise, due to its irreversible deformation, to the perforation of the film by the sharp edges 10 of the relief bordering the transfer orifice. This invention offers its user a brush equipped with its toothpaste, whose independence and simplicity of use is intended more particularly for the hotel trade, for the catering trade, for pharmacies and for supermarkets.

BROSSE A DENT A ALVEOLE GARNIE
Le concept de la brosse à dent jetable avec une capacite de pâte dentifrice incorporée à la tete est connu et a déjà été matérialisé de diverses manierez. Les énumérations et commentaires sur l'état de l'art, brevets suivants permettront de mieux apprécier l'invention.TOOTHBRUSH AT ALVEOLE PACKED
The concept of the disposable toothbrush with a capacity of toothpaste incorporated in the head is known and has already been materialized in various ways. The following enumerations and comments on the state of the art, patents will allow a better appreciation of the invention.

- US N" 1797946 de 1931 dont l'injection du dentifrice se fait lors du brossage - US N" 2550190 de 1951, ici la machine qui réalisera le conditionnement pour la production en série reste à inventer ; - FR N" 1161639 de 1956 qui nécessite un coût de revient inadapté pour l'époque et contient une faible quantité de pâte dentifrice ; - US N" 3589823 de 1969 dont la tête empilée est distincte du manche ; - FR N" 7201985 du 04.01.1972 dont la capacité de pâte et la brosse sont conditionnées de maniere indissociable ; - FR N 72030020 du 21.01.1972 qui est une variante pertinante au NO 7201985 soulevant le problème de la dessication de la pâte à dentifrice ;; - BE N 894029 du 04.08.1982 encore une variante du N 7201985 - FR N 8313179 du 10.08.1983 est originale mais ne résout pas le problème du maintient de la capsule ni de l'éjection dirigée de la pâte dentifrice; - FR NO 8509753 rend plus facile le conditionnement par la presence d'un support de poils amobibles, rapporte par clipsage
I1 semble donc parfaitement évident que le fait de localiser le produit dentifrice dans la tête pour ensuite le faire cheminer au travers de l'embase vers les poils, n'est plus une caracteristique originale pour une brosse à dent autonome. Les inventions susdites ont I'incovénient d'avoir un conditionnement de pâte dentifrice non hygiénique et/ou industriellement irréalisable.- US N "1797946 of 1931 whose toothpaste is injected during brushing - US N" 2550190 of 1951, here the machine which will carry out the packaging for the mass production remains to be invented; - FR N "1161639 of 1956 which requires an unsuitable cost price at the time and contains a small quantity of toothpaste; - US N" 3589823 of 1969 whose stacked head is distinct from the handle; - FR N "7201985 of 04.01.1972 whose paste capacity and the brush are inseparably conditioned; - FR N 72030020 of 21.01.1972 which is a significant variant to NO 7201985 raising the problem of the drying of toothpaste ;; - BE N 894029 of 04.08.1982 another variant of N 7201985 - FR N 8313179 of 10.08.1983 is original but does not solve the problem of maintaining the capsule or the directed ejection of toothpaste; - FR NO 8509753 makes packaging easier by the presence of a removable hair support, attached by clipping
It therefore seems perfectly obvious that locating the toothpaste in the head and then making it travel through the base towards the bristles is no longer an original characteristic for a stand-alone toothbrush. The aforementioned inventions have the disadvantage of having unhygienic and / or industrially impractical packaging of toothpaste.

La brosse à dent selon l'invention remédie à ces inconvénients. The toothbrush according to the invention overcomes these drawbacks.

Elle comporte en un ensemble - Un manche pour la préhension, - D'une alveole garnie de dentifrice et opercule par un film enserrée, par au moins deux des cotés de son embase dans une glissière ménagee au dos de la tete empoilée. It comprises in a set - A handle for gripping, - A cell filled with toothpaste and sealed with a film wrapped, by at least two sides of its base in a slide housed on the back of the stacked head.

- D'au moins une aspérité saillante localisée dans le siège de l'alvéole, en regard avec le film permettant d'amorcer sa perforation sous une faible pression, toutefois pour éviter une perforation accidentelle lors de la mise en place, un bossage le haut de l'aspérité vers le fond du siège relevant l'embase insérée dans la glissière.- At least one protruding roughness located in the seat of the cell, facing the film allowing to initiate its perforation under low pressure, however to avoid accidental perforation during installation, a boss on the top of the roughness towards the bottom of the seat raising the base inserted in the slide.

L'insertion de l'alvéole peut se faire selon le sens longitudinal de la tète empoilée. I1 est avantageux que le materiau de l'alvéole lui permette de se déformer de manière plastique, l'alvéole restant escamotée après l'éjection de son contenu. Le film refermant l'alvéole devra avoir une résistance à la perforation à celle de l'alvéole. The insertion of the socket can be done in the longitudinal direction of the stacked head. I1 is advantageous that the material of the cell allows it to deform plastically, the cell remaining retracted after the ejection of its contents. The film closing the cell must have a puncture resistance to that of the cell.

Les caractéristiques de l'orifice de trasnfert sont:
D'être d'une section superieure à celle d'une touffe de poils et d'être entoure de touffes de poils afin d'offrir une faible résistance à l'écoulement et un gainage au produit dentifrice.The characteristics of the transfer port are:
To be of a section larger than that of a tuft of bristles and to be surrounded by tufts of bristles in order to offer low resistance to flow and sheathing of the toothpaste product.

LesXmateriaux constitutifs du manche sont des résines polyester, polyamide, polyuethane ou autres matières plastiques rigides
L'alvéole est en polycarbonate ou polypropylène de 1 à 2/lOeme mm d'épaisseur et le dentifrice à base. Le film est en aluminium d'une épaisseur de quelques centièmes de millimètre.The constituent materials of the handle are polyester, polyamide, polyuethane resins or other rigid plastics
The socket is made of polycarbonate or polypropylene 1 to 2/10 mm thick and the toothpaste based. The film is made of aluminum with a thickness of a few hundredths of a millimeter.

- Dans la figure 1, le manche (1) a à son extrémité, une tête empoilée (2), une alvéole operculée (5), partiellement représentée, engagée dans son siège (3) à glissière (4) et un orifice de transfert (9) délimité à l'avant par des aspérités saillantes (10), à l'arrière par une élévation servant de guide pour l'embase (12) de l'alvéole.- Figure 3 shows the flow of toothpaste to the hairs
- In Figure 1, the handle (1) has at its end, a stacked head (2), a sealed cell (5), partially shown, engaged in its seat (3) slide (4) and a transfer port (9) delimited at the front by projecting projections (10), at the rear by an elevation serving as a guide for the base (12) of the cell.

- La figure 2 représente l'alvéole (5) garnie de son dentifrice (7) en opercule par un film (6) colle sur l'embase (12). - Figure 2 shows the socket (5) filled with its toothpaste (7) in the lid by a film (6) glued to the base (12).

La figure 3 est une coupe longitudinale de la tette empoilée (2) de la brosse passant par l'orifice de transfert (9) de la périphérie avant est pourvue d'une aspérité saillante (10) et l'arrière est prolongé par un bossage (11). Figure 3 is a longitudinal section of the stacked tette (2) of the brush passing through the transfer orifice (9) of the front periphery is provided with a protruding asperity (10) and the rear is extended by a boss (11).

Le manche de la brosse est réalise de préférence par injection de plastique dans un moule métallique. The handle of the brush is preferably made by injecting plastic into a metal mold.

Le poilage est retenu dans les orifices de la tête par des agraffes métalliques ou par collage. L'alvéole est thermoformée ou emboutie sur sa matrice et le film adhère à l'alvéole, qui est garnie de son dentifrice, en étant colle, soudé ou fortement comprimé. The hair is retained in the openings of the head by metal staples or by gluing. The cell is thermoformed or stamped on its matrix and the film adheres to the cell, which is filled with its toothpaste, being glued, welded or strongly compressed.

I1 est entendu que l'invention est decrite à titre d'exemple préférentiel et des equivalences à ses éléments constitutifs realisant les memes fonctions peuvent être utilisés sans sortir du cadre de l'invention. It is understood that the invention is described by way of a preferred example and equivalences to its constituent elements carrying out the same functions can be used without departing from the scope of the invention.
