Abstract

A hair conditioning device (1) allows an optimal selection and isolation, such that the conditioning substance operates exclusively onto a selected lock of hair (H), and comprises a first valve-shaped member (2) and a second valve-shaped member (3), apt to be fit together forming a closed chamber (7, 8) therebetween, and removable fitting means (4, 5, 6) of said first and second valve-shaped member (2, 3).

Description

The present invention relates to a hair conditioning device, used on a hair lock selected in the context of a conditioning operation.
For hair conditioning it is to be understood any hairdressing treatment in which conditioning substances are applied to a hair lock in order to modify the appearance thereof.
For instance, a bleaching treatment of a hair lock that will then be subjected to dyeing is a typical example of conditioning in accordance with the afore cited definition.
Other possible conditionings are the dyeing, the curl straightening treatment, the perm hairdressing treatment, the strengthening treatment, the nourishing treatment and so forth.
In particular, conditionings are known in the art in which only a specific hair lock is to be treated, e.g. in order to make it different from the other hair locks, as in the streak dyeing.
In such a case, the hair lock to be conditioned has to be isolated from the others, in order to prevent a possible interference of the conditioning substance used with the adjacent hair locks, therefore thwarting the purpose of the conditioning.
Conditioning devices by which a selection and an isolation of the hair lock to be conditioned is carried out are known in the art.
Usually, strips of a waterproof and easy to cut sheet material, e.g. aluminum foil, are used in such devices, wherewith the hair lock is enveloped prior to its being soaked in the conditioning substance.
After the administration of said substance the hair lock is laid down on the remaining hair, isolated therefrom by the sheet material.
Usually, such devices are prepared at the moment they are needed by the hairdresser, to whom a remarkable manual skill, as well as a certain waste of time, are required, however not sufficient to obtain a really effective isolation.
The technical problem underlying the present invention is that of providing a device allowing to overcome the drawbacks mentioned with reference to the known art.
Such problem is solved by a hair conditioning device comprising a first and a second valve-shaped member, apt to be fit together forming a closed chamber therebetween, and removable fitting means of said first and second valve-shaped member.
The main advantage of the hair conditioning device according to the present invention lies in its allowing an optimal selection and isolation, in order to allow the action of the conditioning substance exclusively on a selected hair lock.
The present invention will be hereinafter disclosed according to one of its preferred embodiments, given by way of example and not for limitative purposes, referring to the examples herebelow and to the annexed drawings, wherein:

figure 1 is an exploded perspective view of a hair conditioning device according to the present invention;
figure 2 is a side view of the device of figure 1;
figure 3 is a plan view of the device of figure 1; and
figure 4 is a perspective view of the device of figure 1 in the course of an application thereof in a hairdressing process.

With reference to the figures, a hair conditioning device is globally indicated with 1.
Such device is substantially pincer-shaped with elongated pliers, having a first valve-shaped member 2 and a second valve-shaped member 3 rotatably hinged by a pincer member 4.
Preferably, said valve- shaped members 2, 3 of the present embodiment are made of a transparent, semirigid, strainable and partially flexible plastic material, e.g. polycarbonate, a vinyl chloride resin, a polyethylene or the like.
They are apt to be approached, having a concordant curving, overlapping edges and a substantially trapezoidal outline, elongated into a spatula.
Each valve- shaped member 2, 3 has a first and a second raised rim 5, 6, respectively, apt to be approached and to be fit together.
The raised rim 5, 6 of each valve- shaped member 2, 3, contouring the entire respective member, delimits a respective first and second hemichamber 7, 8, located over the entire inner face of the valve-shaped member.
In the present embodiment, the pincer member 4 and the raised rims 5, 6 form removable fitting means of said first and second valve-shaped member 2, 3.
It is understood that the pincer member 4 and the raised rims 5, 6 are deliberately reduntant, in order to ensure a better adhering of the valve-shaped members.
In other embodiments of the present invention, said fitting means may alternatively comprise either the raised rims 5, 6, provided that the above-described restrained joint suffices to fit together the valve- shaped members 2, 3, or exclusively the pincer member 4, possibly provided with a spring system in order to keep the valve- shaped members 2, 3 pressed together.
By virtue of the shape thereof, said valve- shaped members 2, 3 are apt to be fit together forming a closed chamber therebetween.
The device 1, due to the shape of the valve- shaped members 2, 3, has an elongation extending from said pincer member 4 to an insertion end 9.
At the insertion end 9, the respective raised rims 5, 6 are shaped so as to allow the passage of a hair lock, indicated as whole with H (figure 4).
The pincer member 4 has a pair of jaws 10, to which a respective valve- shaped member 2, 3 is fit.
Accordingly, at an end thereof facing said insertion end 9, each valve- shaped member 2, 3 has a rib 11, apt to be inserted, or removably fixed, into a corresponding groove 12 formed onto the outer rim of each jaws 10.
The groove 12 runs through the respective jaws 10, allowing the corresponding valve- shaped member 2, 3 to be inserted and extracted.
In order to fix the valve- shaped member 2, 3, the groove 12 has a cleft portion 15 in which the corresponding end of the valve- shaped member 2, 3 is fixed, although it can slide sideways.
The jaws 10 are rotatably hinged at a pin 13, housed in a suitable hole 14, formed through said jaws 10.
With reference to the above described device 1, hereinafter a description of the operation thereof will be provided, with reference to the particular case of conditioning carried out with fluid bleachers that are applied during dyeing operations, e.g. to perform streak dyeing.
Inside of each hemichamber 7, 8 a semifluid conditioning substance is positioned, apt to soak a hair lock for the bleaching thereof.
For this purpose, the hairdresser selects a lock of hair H from the hair, and inserts it between the valve- shaped members 2, 3, letting the lock of hair H pass through the insertion end 9.
Then, the valve- shaped members 2, 3 are approached and the lock is imprisoned inside the chamber thus formed.
The removable fitting means, in particular the mutually fixed raised rims 5, 6, seal said chamber and prevent the outflow of the conditioning substance and/or of the hair of the lock H.
Thus, said lock H is isolated from the remaining hair and it can be released onto the latter, provided that said device, as a consequence said fitting means, remains dangling from the head of hair itself.
Obviously, a large number of locks can be treated at the same time, employing a corresponding number of devices 1 with no interference among locks, that therefore can also undergo different treatments at the same time.
Through said valve- shaped members 2, 3 that are conveniently transparent, the hairdresser can perform a visual check of the conditioning in progress.
For this purpose, it is required for at least one of said valve- shaped members 2, 3, and preferably for both, to be transparent.
Once the conditioning has ended, the device 1 can be opened releasing the conditioned lock H, and, after a possible washing and/or replacing of the valve- shaped members 2, 3, it can be promptly reutilized.
Among the possible variants, the fact that the jaws members can be of any shape, and can also differ therebetween themselves provided they fit together forming a sealed chamber apt to house a lock is noteworthy.
Further, in each valve-shaped member, a predetermined quantity can be set beforehand. Thus, a valve-shaped member can be provided already filled up of substance and with a removable film sealing the respective hemichamber.
Possibly, the conditioning substance can be arranged in a gel.
Besides the above-mentioned advantage, the above-described device can be used in a large and simultaneous quantity, possibly allowing the hairdresser to use different types or doses of substances, therefore giving him the chance to control the conditioning under way.
Moreover, such device always allows anyhow to select a lock of any thickness, making it possible to imprison even a large quantity of hairs, possibly curly ones as well, between the valve-shaped members.
To the above-described hair conditioning device a person skilled in the art, in order to satisfy further and contingent needs, may effect several further modifications and variants, all however comprised within the protective scope of the present invention, as defined by the annexed claims.
