Definitions
- the present invention relates to a toothbrush. We know that for dental hygiene, it would be desirable to brush your teeth after each meal. Modern life does not lend itself to such obligations because most of the active people take their midday meal outside their home, either in the canteen, in the restaurant, etc.
- This toothbrush consists of a body formed by a hollow handle intended to be filled with a pasty tooth-cleaning product and a brushing element provided with bristles arranged laterally in the vicinity of the end of the handle, the latter being formed of two parts which have at their corresponding end means for their end-to-end fixing, the first part being provided with bristles, while the second part forms a reservoir for the pasty tooth cleaning product and comprises, at one end, a pasty product flow hole, and at the other end means for controlling a piston housed in the tank and intended to drive the pasty product through the flow hole.
- the piston is provided with a threaded central hole into which a threaded rod is screwed, one end of which passes through a plug from the end of the second part opposite to that provided with the drainage hole and is integral with the control means.
- piston formed by a pusher.
- This toothbrush of simple construction, allows, when the two parts are separated, to apply toothpaste to the bristles and to brush the teeth while having transported the toothbrush and the toothpaste in a jacket pocket or in a handbag.
- the toothpaste flows by unscrewing the pusher, which causes it to move away from the reservoir, then by axial thrust on the pusher by bringing it closer to the reservoir, which directly causes the axial displacement of the piston and the flow of toothpaste. It can therefore be seen that the quantity of toothpaste whose flow has been caused will depend on the number of turns of the pusher, in other words the distance which has been caused between the pusher and the reservoir.
- the user will try to control the pusher with one hand, the other hand holding the brushing part.
- the dose of toothpaste that the user applies to the hair will vary considerably from one use to another and may be excessive. This excess toothpaste will result in the accelerated emptying of the reservoir, the volume of which is necessarily limited due to its small dimensions.
- the present invention therefore aims to remedy the drawbacks of the toothbrush described above by proposing to provide a toothbrush with a toothpaste dispenser.
- the toothbrush device is of the type comprising a hollow handle intended to be filled with a pasty tooth cleaning product and a brushing part provided with bristles, the handle and the brushing part being provided means for their mutual fixing end to end.
- the handle forms a reservoir for the pasty product and comprises at a first end a flow hole for said pasty product and at a second end means for controlling a piston housed in the reservoir and intended to drive the pasty product through the drain hole.
- the piston includes a tapped central hole cooperating with a threaded rod, one of the ends of which passes through a plug of the second end of the reservoir and is integral with a piston control button, the threaded rod and the control button being movable in rotation and translation.
- the toothbrush device includes means for limit the axial stroke of the piston, these means being arranged between the piston and the plug, and being axially integral with the rod.
- the volume of toothpaste expelled by the piston being proportional to the axial stroke of said piston, the limitation of its axial stroke results in a limitation of the amount of toothpaste used during application to the brushing part.
- the means for limiting the stroke of the piston are integral in rotation with the rod.
- the threaded rod and the means for limiting the piston stroke can be in one piece.
- the means for limiting the stroke of the piston comprise a disc with a diameter greater than that of the threaded rod and provided with a stop surface capable of coming into contact with the corresponding surfaces of the plug.
- the control button moving away from the reservoir.
- the threaded rod and the disc have traveled a distance corresponding to the predetermined dose, the disc comes into contact with the stopper, which causes it to block.
- the abutment surfaces of the disc and the stopper may be provided with pins intended to prevent the relative rotation of the disc relative to the stopper after they have come into contact.
- the disc is located at a maximum distance, for example 1.7 mm, from the stopper, this distance being proportional to the volume of pasty product desired.
- the control button is movable in translation and in rotation and is mounted integral with the threaded rod.
- the invention there is a toothbrush provided with a reserve of toothpaste allowing a given number of uses.
- the user knows in advance the number of brushings he can perform with his toothbrush. It is also possible to provide a system for indicating the number of brushings remaining available, for example by providing the tank body with a transparent and graduated wall portion through which the user can see the piston.
- FIG. 1 is an exploded perspective view of a toothbrush according to the invention
- Figure 2 is a sectional view of the toothbrush of Figure 1
- Figure 3 is a detail view of the threaded rod and the stroke limiter of Figure 2
- FIG. 4 is a side elevation view of the cap of the toothbrush of FIG. 2.
- the toothbrush comprises a piston body 1 of elongated shape, provided with a hollow interior 2 of cylindrical shape, forming a reservoir and open at a first end 1 a open of the cylinder body 1.
- a second end 1b of the cylinder body 1 comprises a male part le projecting outwards and provided with a lug for joining 3.
- the hollow interior 2 serves as a toothpaste reservoir and communicates with the outside via an axial orifice 2a provided in the male part.
- the toothbrush also comprises a brush body 4 of which only one part is visible in FIG. 1, the other part being disposed inside the cap 5.
- the brush body 4 is provided with a hollow portion 4a of shape adapted to the male part of the cylinder body 1 and provided with a locking ramp, not shown, capable of cooperating with the lug 3 for the mutual attachment of the cylinder body 1 and the brush body 4.
- the end of the brush body 4 disposed in the cap 5 is provided with rows of bristles for brushing the teeth.
- the cap body 5 is provided to surround the brush body
- the cap 5 is also provided with a tongue 6 fixed to the closed end of the cap 5 and extending along the latter so as to be able to carry the toothbrush in a pocket like a pen.
- the toothbrush comprises a piston 7 capable of moving in translation in the reservoir 2 of the cylinder body 1, but of non-circular shape and concordant with that of the section of the tank 2, so as to be integral with rotation of the cylinder body 1.
- the piston 7 is axially traversed by a tapped hole 7a in which is disposed a threaded rod 8 extending substantially over the entire length of the reservoir 2.
- the threaded rod 8 extends towards the outside of the reservoir 2 by a circular disc 9 with a diameter greater than that of the threaded rod 8, and by a cylindrical portion 10 projecting outside the cylinder body 1.
- a plug 1 1 in the form of a sleeve fixed to the cylinder body 1 and pierced with a cylindrical hole l ia through which the cylindrical portion 10 passes.
- the cylindrical portion 10 remains free in rotation relative to the plug 1 1.
- the plug 11 is provided with a radial annular surface 1 lb facing a corresponding surface 9a of the disc 9.
- the annular surfaces 9a of the disc 9 and 1 lb of the plug 11 are capable of coming into contact and are both provided with lugs 9b on the surface 9a ( Figure 3) and lugs l ie on the surface 11b ( Figure 4) arranged so that the lugs 9b protrude between the lugs l ie, and vice versa, when the disc 9 is brought closer to the plug 11.
- the cylindrical portion 10 supports a control button 12 of cylindrical shape partially surrounding the plug 11 and the cylindrical portion 10.
- the control button 12 can be provided with irregularities on its outer surface 12a so as to facilitate its gripping. These irregularities can take the form of bosses, spikes, axial grooves or the like.
- a cap 13 is fixed to the free end of the cylindrical portion 10.
- the toothpaste is placed in the reservoir 2 on the side of the stopper 7 opposite the disc 9 and is intended to flow through an orifice 2a of the reservoir 2.
- the user first removes the stopper 5 from the toothbrush and then separates the brush body 4 from the cylinder body 1. Then the user causes the rotation of the control button 12 which drives the cylindrical portion 10, the disc 9 and the threaded rod 8. Due to the engagement of the threads of the threaded rod 8 in the threaded hole 7a of the piston 7, the threaded rod 8, the disc 9, the cylindrical portion 10 and the control button 12 move not only in rotation but also in translation relative to the cylinder body 1, according to a movement helical.
- This helical movement is stopped when the lugs 9b of the disc 9 come into contact with the lugs 1 on the plug 1 1. This contact between the lugs 9b and 1 causes it to stop both the axial component and the circular component of the helical movement.
- the invention there is a simple and economical manufacturing toothbrush that can be made of synthetic material and perfectly suited to its use during meals taken outside the user's home as well as during trips. or travel.
- This toothbrush incorporates a toothpaste reservoir corresponding to a predetermined number of toothbrushes which can be known to the user, which reduces the number of replacements of the toothpaste reservoir. This toothbrush is therefore particularly simple to use.
