Definitions

  • the tooth-brush with container for tooth-paste and system for squeezing out tooth-paste in accordance with the International classification of patents can be classified in the sphere which is dealing with brushes in general A 46 B. More precisely, the class is A 46 B 11/02 and comprises brushes with containers or other means for dosing of toothpaste, where the tooth-paste is emptied from container under pressure. Beside the mentioned one, the near by classification is B 65 D 83/00 and comprises containers with special ways of emptying their own contents.
  • the technical problem that is solved by our invention is a conjunction of the classical type of tooth-brush with container for tooth-paste in the way to obtain the functional unity, which meets not only the high ergonomic and aesthetic requirements but the one which is far more important - hygienic procedure of bringing the tooth-paste on the tooth-brush itself by using one-way valve, as well as the perfect protection of the brushy part of the tooth-brush.
  • the second advantage is the simple design which reflects in the minimum number of parts, as well as in the elegant solution of showing the level of tooth-paste that is squeezed out.
  • the drawing No. 1 shows the outside appearance of the invention of the new type of tooth-brush with container for tooth-paste and with the system for squeezing out the tooth-paste placed in the holder of the brush (hereinafter referred to as brush).
  • the already mentioned function of the container and the brush itself is united in the way that these two objects become one ergonomic, unseparated unit.
  • the drawing No. 2 shows the longitudinal crosscut with corresponding views on details of the more important crosscuts.
  • the positions on the drawing No. 2 are:
  • the detail A and the sight A on the drawing 2 show the crosscut of the activation button and the piston guide, and the sight of the activation button and the toothpick closet.
  • the detail B and the crosscut B on the drawing 2 show the crosscut and the way of sealing on the places of leaning the piston with seal on the wall, as well as the part of piston through which the filling of tooth-paste is performed.
  • the detail E shows the way of leaning the activation button on the piston guide.
  • the detail F shows the way of leaning the hairy protection on the basic brush body.
  • the drawing 3 shows the design of brush emphasising appearance and distribution of hairs (detail L), the view E is the view from above on the brush, and the view F is the view from underneath on the brush, the view G is the view from front side, the view H is the view from behind to the end with activation button, the detail K is the detail of the connection of the activation button and the very body of the brush.
  • the drawing 4 shows the views of the body, which permit better understanding of the construction itself.
  • the view A is the view from above, the view B from underneath, the view C from the front side, and the view D is the view of the internal part of the body itself.
  • the drawings 5 through 13 show the parts which are the component parts of the brush.
  • the drawing 5 shows the design of the activation button.
  • On the drawing 6 is the sliding ring in both relevant projections.
  • the drawing 7 shows the leaning cover of the one-way valve in two sights.
  • the drawing 8 shows the laminated spring in two sights.
  • On the drawing 9 is the sight of the piston guide with relevant views, while the piston itself is shown on the drawing 10 in two positions so that his design would be more clear.
  • the drawing 11 shows three views on the sabre shape toothpick.
  • the drawing 12 shows already mentioned screw, serving as a support, while the drawing 13 shows the protection for hairy part of the brush in two projections.
  • the tooth-brush with container for tooth-paste and system for squeezing out tooth-paste placed in the holder consists of small number of elements which meet the already mentioned requirements: unification of functions of the tooth-brush and the tooth-paste container, simplicity and successfulness of the application, and certain hygienic requirements in this connection.
  • the basic part and the carrier of the other parts is the body of the brush itself (1), drawing 2.
  • the body itself has the multiple function: it is the tooth-paste container, it provides delivery of tooth-paste on the one-way valve and is the carrier of the hairy part (9) which function is the same as that of the classical toothbrush.
  • the body In its crosscut the body is round with flattened piston guides, drawing 2, crosscut B-B.
  • the drawing 2 there is one-way valve derived from laminated spring (drawing 8) and the leaning cover (drawing 7).
  • the laminated spring in form of stylised figure 8 with spring up mechanism in the very centre and slightly bent in order to resist from being drawn downward, detail D, crosscut D-D, drawing 2.
  • the leaning cover of the one-way valve (drawing 7) is inserted in the laminated spring in the way that by its neck it jumps in its centre thus being caught for its "upper head", while its lower, but larger part, leans on the channel opening through which the toothpaste is passing.
  • one-way valve The function of one-way valve is double: first of all, when the sufficient pressure is obtained in the channel, the tooth-paste begins coming out (the resistance of the laminated spring is surmounted), and when the outside air pressure and the inside pressure of the tooth paste are equalised, it is prevented, during tooth brushing, the penetration of water and later on the air in the tooth-paste container, thus preventing the paste degradation like oxidation, dehydration etc.
  • the protection for the hairy part (10) is put on the body itself, drawing 2, in the way shown in details D and F. The protection is meant to protect the hairy part from damaging and contamination with impurities.
  • drawing 2 The pressure in the body itself (1), drawing 2, is obtained by manual turning of the activation button, shown on the drawing 2, detail and view A.
  • drawing 5 which is in fact merged into the inner piston guide, drawing 9, the move of the piston, in the very space of the body is obtained, the volume of tooth-paste is being diminished and consequently the pressure is generated which causes the opening of oneway valve.
  • a sliding ring (drawing 6) is mounted between the body and the activation button in the way that it is placed on the part of button which enters the body as shown on the drawing 2, detail A.
  • connection between the activation button (2) and the piston guide (4) is effected in the way shown on the drawing 2, detail E, where one can see the standard way of leaning by jumping in (2) to the end of (4).
  • this way (2) and (4) (see detail A and E, drawing 2) become united as if they have been made of one single piece.
  • the sliding ring (5) is put in, which, beside its aesthetic component, is meant to diminish friction between activation button (2) and the body itself (1).
  • the guide (4) is mounted (springy) on the classical screw (11) which is situated in the body (1), reinforced by rib (12) having the role of carrier, drawing 2, crosscut C-C, detail C.
  • piston In order to permit the undisturbed work of the invention itself as well as to enable the efficient filling of the ready made product, the construction of piston is of extreme importance.
  • the piston is in its construction modified circle, drawing 10, with lateral smoothness, concentric opening - coil for acceptance of the coil of the piston guide. Beside the mentioned opening, the piston has another opening through which is effected the filling procedure, which can be seen on the lateral projection of the drawing 10.
  • the sealing is to be effected in the way that there would be no loss of tooth-paste pressure so that the power from the activation button be, by means of piston, transferred to the tooth-paste, and by mediation of tooth-paste to the laminated spring of the one-way valve.
  • the lateral smoothness prevent the rotation of piston in the space of the body and carry it down the coil of the guide. This is extremely important in order to assure the liability of the work of invention, i.e. that every turn of the activation button may perform the proportional change of pressure in the container, in order to avoid possible idle run.
  • the toothbrush is assembled in the way that the parts (7), (8), (9) and (10), drawing 2, are mounted on the body (1) in the already mentioned way.
  • the screw (11) is laid into the body and thus the preparation of one part of the body is completed.
  • the following step is the mounting of piston guide (4) with piston (3) by putting them almost at the end of the guide itself, approximately 1 do 1,5 turns up to the so called "upper point" of the maximum capacity of the tooth-paste container.
  • the guide (4) is springy connected to the screw (11).
  • the piston itself has a specially designed part (13), which is in fact the small tube of the corresponding diameter through which the nozzle can be introduced, which length can be almost as the length of the body itself (1).
  • a specially designed installation which is not the subject of invention, such nozzle can be introduced through (13) starting the injection of the tooth-paste from the head of the brush to the beginning, retreating by constant speed.
  • the piston is on the opposite end, at the position of the "upper point", while the complete body is vibrating so that the entering paste could evenly take the volume of the body, thus squeezing out the residual air.
  • the very end (13) is closed by special tool, by melting, gluing or similar procedure, depending on material the piston is made of (13).
  • the container is filled with tooth-paste and it is to be started the assemblage of the activation button (2) and sliding ring (5) on the already mentioned way - by springing in (2) to (4) as shown on details E and A, drawing 2.
  • the activation button is additionally turned for 1 to 1,5 turns up to the very end, which insures the vacuum in the container, providing better sealing of the one-way valve leaning cover.(8).
  • the sabre shape toothpick shown on drawing 11. Its shape, the sabre shape, permits the liable emplacement inside the activation button and piston guide, as shown on detail A and crosscut B-B, drawing 2, and this in the way that by friction it is fixed inside the guide itself, while its head is sticking out from inside the button. In this way it is easily taken out and after use it is easily put on its place again.
  • the activation button has grooves which improve the finger contacts (especially wet ones) and button when being turned.

Abstract

La présente invention concerne une brosse à dents avec un récipient renfermant la pâte dentifrice et un système permettant de faire sortir la pâte dentifrice et comprenant un minimum de pièces toutes montées dans ou sur le corps (1), à savoir guide de piston interne (4) avec bouton de commande (2), bague coulissante (5), couvercle (8) de soupape unidirectionnelle, ressort à lame (7), piston (3) et cure-dents (6). En tournant, le bouton (2) agit sur le ressort, lequel appuie lui-même sur le guide de piston (4), ce qui a pour effet de chasser le dentifrice au travers de la soupape unidirectionnelle (7 et 8) sur le côté brosse de la tête de brosse à dent. Que ce soit pendant l'utilisation ou non, la soupape unidirectionnelle empêche la pénétration d'eau et d'air dans le logement à dentifrice, et donc le déclenchement de processus chimiques indésirables sur le dentifrice lui-même, ce qui contribue à préserver l'hygiène de la brosse. Le capuchon (10) protège la partie poils de la brosse.
