Description

1 APPLICATION TOOTH FOR HAIR AND/OR SCALP TREATMENT OBJECT OF THE INVENTION The present invention, as stated in the title to this specification, relates to an application tooth for 5 treating the hair and/or scalp, with which enhancement is obtained of the benefits offered by the existing systems for applying both liquid and viscous products currently employed, though in a more precise, cleaner and quicker manner than is achieved with these conventional methods, 10 providing also a considerable saving in the amount employed of said products. BACKGROUND TO THE INVENTION The systems that are presently being employed for applying different hair products, have the disadvantage 15 that, for specific applications (for hair and scalp independently), they are insufficiently precise for the application process and this, in the long run, can lead to problems, if not for the hair itself, then for the scalp due to products producing irritation when coming into 20 contact with it. In the utility model U-9601817 of the same applicant as the present invention, a perfected comb was made known for hair treatment, the object of which is to facilitate the application of liquid products such as lotions, dyes, 25 etc., in less time, with greater safety and cleanliness, than when employing the methods of conventional systems. It comprises a comb having a hollow main body constituent part of a reservoir for holding the liquid to be used in the treatment. This body leads into tubular teeth the 30 operational ends of which form a curved concave line, instead of terminating in a straight line as is normal practice. The means of impelling the product consists basically of flexible segments in the handle, permitting pressure to be applied manually. 35 In the international application PCT/ES97/00167 by 2 the same applicant, a comb was made known for hair treatment in which, in addition to the features offered by the aforementioned utility, other benefits are provided such as those indicated below: 5 The product reservoir is at least in part in the form of a main body from which the teeth radiate, said body having a mouth joined through a means of opening and hermetically closing to the handle. The reservoir incorporates a refillable and/or replaceable cartridge. 10 The teeth can come with a bevel cut and also have multiple perforations practised along them and also incorporate a small brush. DESCRIPTION OF THE INVENTION In general lines, the application tooth for hair 15 and/or scalp treatment, which comprises the object of the invention, basically offers a feature of interchangeability whereby a single support is capable of being used for different applications of products and treatments for the hair or scalp. 20 These teeth, in the number of units specified, are coupled or attached to the body acting as common head and which can come in different forms. To this body is fitted an adapted container or receptacle and which is the element that may hold the hair products. On mounting the 25 head on this container, if the latter holds any hair product, the teeth attached absorb a certain amount of said product by capillary action, or else by manual pressure on the pertinent pliable segment or pushbutton, it being possible thereby to apply the product to the hair 30 or scalp according to the version of teeth being employed, as required by the user. By means of a set of teeth, the structure and distribution of which differ for each application, in accordance with the different versions which shall be 35 remarked later in connection with the figures, a perfect 3 application can be achieved. These teeth can come joined together forming a unit for assembly or replacement, or separate from each other, since certain tooth models or versions cannot be produced as a block. For their use the 5 teeth can be inserted in the body which has been defined as head for a container or receptacle and which at the same time protects the teeth connected to it. The body serving as head, can come in different shapes, hold one or more application teeth, in line or 10 alternated and having different geometric forms. It can also have a concave base to adapt anatomically to the user's head. As has been indicated above and depending on the application, a first type of tooth has been foreseen 15 having a design to deposit the product on the scalp alone, when the hair is being combed, by means of a permeable fibre which is attached to the back part of the tooth. In this manner, the front part of said tooth provides a means of support and guidance which produces a tiny furrow in 20 the skin of the scalp which the fibre makes use of to impregnate the scalp with the product, avoiding the adsorption of said product by the hair. Another type of tooth for another application or treatment, mainly for applying viscous products to the 25 scalp or at the base of the hair, incorporates at the operational end, a number of bristles inserted on the back part to facilitate the application process. This arrangement is similar to that mentioned above, the permeable fibre being replaced by bristles. 30 There is another type of application tooth designed to prevent products coming into contact with the scalp, since there are some of these which are harmful to it, such as anti-parasitic lotions. This last type of tooth mentioned, has both the front 35 and rear of the lower part stiff, while the rest is of 4 permeable fibre. Thus, the product can be deposited on the hair when combing, but is prevented from reaching the scalp and hair roots. To permit the application of the product indistinctly 5 to the hair and the scalp, stiff-cored teeth can be employed with a permeable fibre cladding which retains the product. For applying gels or viscous products intended for the hair, teeth can be used with a cladding provided with 10 longitudinal recesses or holes which facilitate the emission, these being possible with or without fibre. For those applications in which it is necessary for any of the different versions of teeth to have the product continuously available, the head can be fitted with a 15 dosing mechanism which controls the flow of the product to be sent to the application tips connected to the dosing mechanism, said product coming from a cartridge which can be self-actuating. This cartridge can also be refillable or disposable. 20 To maintain the product in perfect condition, the cartridge comes fitted with a cap having a vacuum valve and in this case the container or receptacle serves to 4 permeable fibre.

To facilitate a better understanding of the 25 characteristics of the invention and forming an integral part of this specification, a number of drawings are attached in which figures, in an illustrative and not restrictive manner, the following aspects are shown: BRIEF DESCRIPTION OF THE FIGURES 30 Figure 1.- Shows a partial longitudinal side view of a comb which includes a set of application teeth for hair and/or scalp treatment, in accordance with the invention. Figure 2.- Shows a side view of that shown in figure 1, with the portion corresponding to the teeth and 35 pushbutton in section.

5 Figure 3.- Shows a partial sectional view, of the end of an application tooth with a permeable fibre on the back part. Figure 4.- Shows a view of the end of an application 5 tooth which incorporates pliable bristles on the back part. Figures 5 to 7.- Show respective views in perspective of different models of application teeth for different hair and/or scalp treatments. 10 DESCRIPTION OF THE PREFERRED EMBODIMENT With reference to the numbering scheme adopted in the figures, it can be seen how the application tooth for hair and/or scalp treatment, which is proposed in the invention, is interchangeable in nature by forming part of 15 an assembly which can be inserted into a tubular body 1 serving as support. The body 1 has connected to it a plurality of teeth 2 of tubular structure through which passes the product held in the container 3 joined to the mouthpiece 4 of the tubular body 1, provided in turn with 20 the axial channel 5 and the side branches 6, mutually coplanar and in line with the core of the tubular teeth 2, as can be seen in figure 1. When the pushbutton 7 is manually depressed, the product to be applied held in the receptacle or container 25 3, is fed into the teeth 2. The teeth 2 are detachable and replaceable to permit their insertion into the body 1 itself of the comb or holder and as has been stated above, depending on the application they have a specific structure and distribution. 30 Thus, in figure 3, a tooth tip model 21 is shown which is employed to deposit the treatment product on the scalp only, by having a permeable fibre 8 on the back part of its extremity. Reference 9 indicates the lateral orifice of the tooth permitting the product to reach the 35 permeable fibre 8. The front part 10 of this tooth 21, 6 being of a stiff material, produces a furrow in order that the back part 8 only applies the product to the scalp. In figure 4 the reference 211 is given to a tooth of which the rear extremity has bristles 11 instead of the 5 permeable fibre 8 of figure 3. As has been indicated earlier, this permits the product to be applied only to the base of the hair or scalp. The application tooth 2111 shown in figure 5, has a structure designed precisely to prevent contact between 10 the product and the scalp, the former being deposited only on the hair when combed. The lower part of the end of the tip and the front and back thereof, are stiff, while on the sides there is a permeable fibre 12 for impregnating the hair. 15 In figure 6, the tooth having reference 21V has a rigid structure sheathed in a layer of permeable fibre 13, suitable for applying the product indistinctly to the hair or to the scalp, permitting all the hair to be moistened or wetted with any type of product. 20 The tooth shown in figure 7, having reference 2 v, works by capillary action in like manner to a pen nib or a draughtsman's pen, having a longitudinal opening 14 through which the product to be applied is fed. The tooth is given this structure in order to permit the application 25 of denser or more adherent products.
