HAIR EXTENSION
A hair extension formed by a lock of hair is fixed with respect to a substantially rigid plate, from a first face of which there extends at least one linear layered tress of hair, the ends of which are fixed head-on to said face, orthogonal to the plane thereof. A second face of the plate is opposite to the first face and carries means for permanent attachment or means for temporary attachment to the hair.
This application is a 371 National Phase of International Application Number PCT/IB2011/054362 filed on Oct. 4, 2011, and published in English on Apr. 12, 2012 as International Publication Number WO 2012/046188 A1, which claims priority to Italian Patent Application No. TO2010A000810, filed on Oct. 5, 2010, the entire disclosures of which are incorporated herein by reference.
FIELD OF THE INVENTIONThe present invention relates to hair extensions of the type comprising a lock of hair rendered fixed with respect to a body made of thermoplastic material provided for anchorage thereof to the hair.
PRIOR ARTTo connect the above sort of hair extensions to the hair of the user so as to lengthen it and thicken it and render it more voluminous, various solutions have been proposed, none of which, however, has proven completely satisfactory.
Hence, for example, in the case of the British patent No. GB-2288976 and of the German patent No. DEA 9626107, the body made of thermoplastic material consists of a strip and of a sheet, respectively, on the internal surface of which there adheres one end of the extension lock, with the corresponding hair set parallel to said surface. For its application, the strip or sheet, respectively, is then folded around the end of the lock of hair and then subjected to heating to bring about softening thereof and finally, following upon subsequent cooling, consequent fixing of the extension on the hair.
In either case, following upon application of the strip or sheet, even though this is partially transparent, it remains visible, and this constitutes an evident drawback of an aesthetic nature. Furthermore, since the extension lock hangs from the strip or sheet parallel to the plane thereof, the so to speak voluminizing effect of the hair extension applied is insufficient or even inexistent, which constitutes a further aesthetic drawback.
SUMMARY OF THE INVENTIONThe object of the present invention is to overcome the aforesaid drawbacks and, more in particular, to provide a hair extension of the type defined above that will enable, following upon its application to the hair of the user, an improved effect of thickening and above all voluminization of the hair to be obtained.
A further object is to provide a hair extension, the element of anchorage of which to the hair is, in the condition where the extension is applied, substantially invisible.
According to the invention, the above objects are achieved basically thanks to the fact that the aforesaid body made of plastic material consists of a substantially rigid plate, from a first face of which there extends at least one linear layered tress of hair, the ends of which are fixed head-on to said face, orthogonal to the plane thereof, and the second face of which, opposite to the first one, carries means for permanent attachment or means for temporary attachment to the hair.
According to a preferred embodiment of the invention, fixed to the aforesaid first face of the plate made of thermoplastic material, starting from its top, are multiple linear tresses of hair set on top of one another and slightly at a distance from one another.
The invention envisages various configurations of the means for attachment to the hair associated to the second face of the plate, whether of a permanent-attachment type, in particular by thermoadhesion, or of a temporary-attachment type, as well as a peculiar method Of application of the extension.
The invention will now be described in detail with reference to the annexed drawings, which are provided purely by way of non-limiting example and in which:
With initial reference to
The plate 1 has an external or dorsal face 1a and an internal or front face 1b, of which the first carries an extension lock of hair designated as a whole by 2, and the second is provided for anchorage thereof to the hair of the user.
According to the peculiar characteristic of the invention, the lock 2 includes at least one linear layered tress of hair, and more conveniently a plurality (in the example illustrated, four) of such linear layered tresses of hair 2a, 2b, 2c and 2d, set on top of one another and slightly spaced apart, starting from the top or top end 1c of the plate 1.
The hair of each linear layered tress 2a, 2b, 2c, 2d is rendered fixed with respect to the dorsal face 1a of the plate 1 as a result of fixing of the respective tips in a direction orthogonal to the said face 1a. To fix the surface of the face 1a, this is heated until it softens, and then the tips of the hair are englobed therein, being inserted, as has been said, in a direction perpendicular to the plane of the face 1a. Said operation can be obtained, also simultaneously for the hair of all the tresses 2a-2d, via a suitable tool for gripping the hair, via application of a heat-meltable adhesive on the face 1a, heating, insertion head-on of the hair, and then fixing thereof following upon cooling. At the end of cooling, the face 1a will englobe in a permanent way the tips of the hair of the various linear tresses set on top of one another 2a-2d, with a “waterfall” effect exemplified in the drawings, which, in the condition where the extension is applied, enables an aesthetically appreciable voluminization to be obtained, in addition to thickening of the hair to which the extension is applied. Furthermore, the plate 1, hidden by the tresses of hair 2a-2d, will be substantially invisible.
For its application, the front face 1b opposite to the dorsal face 1a of the plate 1 can be configured with different alternative systems of permanent attachment or temporary attachment to the hair.
In the case of
In the case of
In the case of
The anchorage systems described so far, which may obviously differ from the constructional standpoint, provide, as has been said, a permanent anchorage of the extension to the hair of the user, in the sense that its possible subsequent removal requires application of a solvent or the like for detachment of the plate 1 from the lock to which the extension has been applied.
The variants represented in
In the case of
In the case of
In both cases, the voluminizing effect that derives from the disposition of the tresses of hair 2a, 2b, 2c 2d projecting in a direction orthogonal to the plane of the plate 1 is, in the condition applied, altogether identical to what has been described with reference to the embodiments of
The same effect is obtained with the further example of temporary application of the plate 1 represented in
The tab 8 includes three consecutive foldable portions A, B, C, where;
the first portion A is joined to the face 1b of the plate 1 on the back 8b of the tab 8, for example via adhesive;
the first portion A, the second portion B, and the third portion C are adhesive on the front side 8a of the tab 8 and are coated with a first anti-adhesive layer or sheet 9 that can be removed upon application of the extensions;
the third portion C is adhesive also on the bark 8b of the tab ‘8 and is coated with a second anti-adhesive layer or sheet 10, removable at the end of application of the extension.
For joining to the face 1b of the plate 1, the first portion A is conveniently adhesive also on the back 8b of the tab 8, whereas the second portion B is adhesive only on the front 8a.
To apply the plate 1 with the tab 8 to a lock of hair the procedure is according to the sequence of steps illustrated schematically in.
First of all, the first anti-adhesive layer 9 is removed so as to expose the adhesive portions A, B, C on the front side 8a of the tab 8 (
Then, the ends of a lock of hair are applied on the second adhesive portion B (
Next, the second adhesive portion B is separated and re-opened with respect to the first adhesive portion A (
Then the second anti-adhesive layer 10 is removed, so as to expose the third adhesive portion C on the back 8b of the tab 8 (
Of course, the details of construction and the embodiments may vary widely with respect to what has been described and illustrated herein, without thereby departing from the scope of the present invention as defined in the ensuing claims.
