Abstract

Toot-brush of the type having a handle which is prolonged by a budging which includes the cleaning head applied against the teeth, characterized in that, unlike known tooth-brushes whose heads are applied with tooth-paste dispensed from a separate paste tube, the present toot-brush incorporates in the cleaning head, conveniently dehydrated or desiccated, the pertinent tooth-paste (p) which will rehydrate when contacting the saliva of the user or by a prior wetting of the head before using it, the head being comprised of an assembly of pins (3) to which the tooth-paste (p) is adhered, or with a spongy or fibrous mass (5) which contains absorbed tooth-paste (p) and which is mounted in an opening (8) of the bulging (2) and secured therein by a plate (10) fitted and fixed in said opening (8) and to which said mass (5) may also be joined. It has also been provided to incorporate in the cleaning head tooth-paste which has not been dehydrated.

Description

Toothbrush

The invention relates to a toothbrush that has significant advantages over those already known.

These brushes are constituted generally by a handle that extends to form a ensachamiento in which are secured, perpendicular to it, few bunches of bristles forming a dense set with that rub, for cleaning the teeth prior smeared with toothpaste tubes going in a separate cartoning. This means that apart from the inconvenience of having to always have a tube dentiírica paste with brush, .propia constitution thereof by inser¬ tion of the bristles on the handle makes it rather expensive manufacturing. These disadvantages are compounded in use, especially in cases where the user frequently travels as the nuisance of having to unclog the tube toothpaste and spreads the brush head, must be added the need to clean the brush every time it is used for obvious hygiene needs, as well as having to be aware of it in case it crashes or _ the toothpaste tube if it runs out, not to be in the most unexpected moment without pasta or brush that clean teeth. With the brush of this invention, these and other nientes inconve¬ arising from them are solved since, although the handle is similar to the existing ones, the toothpaste is incorporated, conve¬ niently dehydrated or dried, in the head cleaner, which is formed by tines of the same material as the handle and which arise from the expansion of the same, forming with it a single unremovable piece can be made of plastic material in an injected sole, which brush low is obtained cost can be discarded after use.

This circumstance will allow the toilets of certain places, such as hotel establishments or schools can provide themselves with these brushes to be a dispo¬ sition users have as soaps or towels, allowing, for example, the person traveling , not having to worry about carry the usual toothbrush and toothpaste with easements that entails.

Advantageously, the cleaning head can also consti¬ tuirse with a mass of spongy or fibrous natural or artificial material, texture and stiffness suitable to act against the teeth and which contains absorbed toothpaste which in this case must be very fluid and easily evaporable liquid in its part so that, once absorbidapor head, it dries quickly and allow subsequent cartoning. This head, not being the same material as the handle, is coupled to it by inserting it into an opening comprise a widening of the handle to which it is suje¬ TARA by a placket that provided with fastening means in the handle, imprison the head by prolongations thereof coupled in corresponding sockets of the widening, avoiding other assembly would need some machinings encarecerían brush.

Also, with this latest version of head, handles higher quality can also be performed, with only the head which is disposable and therefore Reca - biable, said head can also be attached to the fastening placket.

The head can also be attached to the widening of the handle by adhesive or suitable glue, as can also be welded to it according to the material that is fabri¬ ed.

It is also foreseen that the brush embeds in the cleaning head or the dentifrice undehydrated desiccate constituting said head for it with a mass of spongy or fibrous material containing dichor.dentífrico absorbed and has ideal constitution in the area of ​​action against teeth. In addition, the brush can be simplified structurally to further reduce its already low cost by filing the handle, in the end region comprising the cleaning head, two longitudinal branches as a fork, between which said head is arranged near you opposite the action against the teeth, being subject in coupling said branches with a placket them through a longitudinal groove with which it slides, conveniently guided over said branches. Advantageously, the respective inner sides and enfren¬ sults of the end branches have their aforementioned handle edges closest to the active part of the cleaning head, leaving a narrow passage for better imprisoning said head when it latches with the coupling of the placket between the branches of the handle.

This and other features will become better from the following detailed description, to facilitate which is accompanied by two sheets of drawings in which are shown a practical case of embodiment cited only by way of example not limiting the scope of the present invention.

In the drawings:

Figure 1 is a longitudinal view with sectioned head one of these brushes in which the head and handle form a single piece, Figure 2 shows in perspective the brush head about to mount, Figure 3 illustrates in longitudinal section the head of the previous figure and mounted on the handle, figure 4 is a cross sectional view of the same head mounted or the line IV-IV of figure 3, figure 5 'is a plan view of another embodiment of brush with engageable head, exploded, figure 6 shows in perspective the same des¬ brush I piezado but arranged to be mounted, figure 7 illustrates in longitudinal section the brush assembled by the part comprising the cleaning head, and figure 8 is a cross-sectional view of the brush line corteVIII-VTII of figuι_a 7.

According to said figures, the illustrated toothbrush comprises uri handle 1 which extends to form a widening of 2 wherein the cleaning head is located.

This cleaning head may have several versions, one (see Figure 1) is formed with a cylindrical-conical barbs 3 born tentering 2, and perpendicularly to, being at the ends of said tines 3 toothpaste p, of adhesion and adapted so that, after the tines 3 have dipped in a bath of said pulp, have left the same with individual droplets 4 adhered viscosity, which subsequently dehydrate or dry out so that the brush can be handled in operations such as packaging .

Another version of the head is formed with a spongy or fibrous 5 mass containing absorbed the toothpaste py whose area of ​​action against the teeth has a tooth 6, whereas the opposite area comprises lateral extensions longitudinal 7 that, once introduced the head 5 in an opening 8 of the widening 2 of the handle, engage in respective sockets 9 of the opening 8.

A placket subject 10 holds the head 5 in the chamiento ensan¬ 2 by the housing at the opening 8 under said head 5, introduced protuberances 11 comprising said placket 10 in the two longer opposite sides, and by pressure on it, in correspon¬ lace teeth 12 of the opening 8.

It follows from this that, by brush, both these heads described like any other, will rehydrate toothpaste p to contact the saliva of the user where it is to use, or so will pre-soaking in water before its use.

According to Figures 5 to 8, the illustrated toothbrush comprises the handle 1, one end of which is topped with two longitudinal branches 13 fork-receiving coupling therebetween cleaning head 5 '.

This cleaning head 5 'is constituted by a lamina 14 (see Figure 5) of spongy or fibrous material having paths 14 upper and lower layers' more compact to prevent toothpaste undehydrated p'introduced into said head is out of the same , before application against the teeth.

This sheet 14 has its central portion with a finish as a transverse toothing 6 'for acting on teeth, the sheet having also 14, longi¬ tudinalmente the toothing 6', two appendices 15 on opposite sides. The head 5 'is configured by bending and applying the end portions of sheet 14 against each other under the appendages 15 prefolding thereof, one over the other under the central part of said sheet 14.

The two end portions of the sheet 14 comprise, following such application against each other, one way outgoing 5'a head 5 'is fitted between the branches 13 and facing the inner sides and their opposites exterior (Fig. 8) are oblique simétrica¬ mind as a dovetail. These branches 13 thus configured is inserted, perfectly guided, in a longitudinal and trapezoid 16 groove in the cap 10 ', with which coupling the branches 13 is clamped, with the edges of the inner sides thereof and closer to the active head portion 5 ', 5'a outgoing thereof.

Placket 10 'has closed the portion of the groove

16 opposite the input branches of the handle 13 and also includes a rectangular and longitudinal recess

17 at the base of said groove 16 so that if the projection protrudes 5'a head 5 'through the branches 13, does not impede the coupling of the cap 10'.

All the branches 13 and the flap 10 ', once engaged it in that presents the same width and height as the rest of the handle, which comprises at its upper and lower sides respective intermediate longitudinal recesses 18 for removing material which, together with the structural simplicity of the brush, they make it very economical and usable for single use, which can serve the user in a convenient and duly sealed wrapper mind.

The object of the invention, within its essentiality be put into practice in other embodiments differing only in detail from those indicated purely by way of example, which are also covered the protection sought.
