Hair extension

a permanent or non-permanent technology, applied in the field of permanent or non-permanent hair extension, can solve the problems of reducing the bonding force of the hairs, requiring a very long time to be operated, and receiving discomfort, so as to reduce the thickness of the tape, increase the bonding force to keep the hairs together, and reduce the overall weight of the connection

Benefits of technology

The present invention is a hair extension that can be permanently or non-permanently applied, allowing for multiple repeated uses. The tape used is thin and flexible, with hair kept together by the adhesive layer and partially penetrating into the tape holes, resulting in a stronger bond and a lighter connection.

Problems solved by technology

In this step, the hair extension may be substantially sewn, bound or knotted to user's hair, but this thickening way requires a very long time to be operated, considering that a manual and precise handling is requested for each single hair extension.
By these members, also large size hair extensions may be associated to user's receiving hair, but with the serious drawback that the fixing remains visible and perceptible to the user himself, receiving a discomfort feeling there through.
Such means, involving the use of glues, small fixing elements and the like, permits to achieve more or less good results, but in any case they need lengthy application sessions because the operator must fix each single hair extension which cannot have a large size to not make the connection visible to the user and to other observers.
Similar problems are felt where a gluing system is used applied just in the fixing process, e.g. in the method disclosed in U.S. Pat. No. 4,934,387 (Megna) which is particularly burdensome in terms of time, because the adhesive is supplied in a liquid and hot state on the end of each hair extension to be fixed.
By the way, the operator must manipulate with the fingers hot adhesive, with a comprehensible discomfort.
In these application examples with adhesive in anyway requested a complex handling of several elements: additional hairs, adhesive, sleeve, glue gun, being also additionally time consuming.
Moreover, the cured adhesive realizes a sort of ball or skirt which is clearly felt by the touch, decreasing the comfort level of the methodology, making the fixing element visible and thwarting the desired aesthetic improvement of the thickening.
The forced manual character of these methods then implies several problems.
First, the operator must have an extensive experience and practice to be able to execute standardized connections, an occurrence which is not always possible.
Further, beyond the experience, it is extremely difficult to produce even connections: they will be at least partially different to each other, not exactly located along the lines foreseen for the thickening, having variable quality and size.
All the above causes a not perfect quality of the final application, more exposed to obsolescence and with forcedly uneliminable imperfections, high cost influenced by the very lengthy application and by the uneasy availability of experienced operators.
Moreover, the cured adhesive realizes a sort of ball or skirt which is clearly felt by the touch, decreasing the comfort level of the methodology, making the fixing element visible and thwarting the desired aesthetic improvement of the thickening.
Although this system allow to hugely speed up the application of hair extensions, it does not solve the problem of the non perfect connections, resulting in unsatisfying size and possibly even visible.
Finally, a problem detectable in the above mentioned prior art examples is represented by the unsatisfied requirement of being able to decide, at the thickening application stage, whether to make it permanent or to have it applied in a non permanent way.
However, the most relevant problem in the application of this kind of thickening is represented by the thickness of the fixing element, combined with the fixing system.
The latter can be reduced at a minimum thickness e.g. by using an adhesive layer, but the sewn and or woven fixing element should anyway have a weft and a warp suitable to safely keep the hairs secured, in turn inevitably determining a thickness pressed against the hair skin, causing a discomfort feeling.
Further, even in this case, it is extremely difficult to make this kind of thickenings either non-permanent, due to the troubles inherent in the fixing operation, or permanent, mainly for the connection thickness.

Embodiment Construction

[0059]With reference to FIGS. from 1 to 5C, a hair extension, of the weft or layer shaped kind, is indicate as 1 as a whole.

[0060]It has a linear fixing member 2 from which hairs 3 perpendicularly branch, in this embodiment of natural kind, arranged in a flat configuration having a uniform distribution.

[0061]The fixing member 2 is formed by two overlapped tapes 4, 5, provided with inner faces facing to each other, adhered to carry out a fixing strip.

[0062]Between the two tapes, 4, 5 a first adhesive layer 6 is provided, which can be the result of the justaxposition of respective adhesive layer on each of the adhered faces of the tapes 4, 5. Such a justaxposition is therefore the result of a manufacturing step of the hair extension 1.

[0063]Between said tapes 4, 5 the proximal ends 7 of the hairs 3 are entrapped, embedded into the adhesive layer 6.

[0064]In the manufacturing step, both the tapes can be provided with hairs arranged with the proximal ends 7 thereof aligned and uniformly ...

Abstract

A hair extension has a linear fixing member from which hairs perpendicularly branch, arranged in a flat configuration and is formed by two flexible tapes adhered to each other to form a fixing strip, with hairs embedded between the two flexible tapes by a fixing adhesive layer arranged therebetween. The tapes are flexible and made of thermoplastic material provided with a plurality of through holes over the surface thereof. The linear fixing member has at least one uncovered adhesive face provided with a pressure-activated and non-permanent further adhesive layer. The tapes are pressed against each other, so that the hairs and the adhesive material of the fixing adhesive layer are at least partially penetrated into the through holes, and the exposed adhesive face forms a support surface for a plurality of peelable films, each separated from the other by a further non-permanent adhesive layer.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention is related to a permanent or non-permanent hair extension, of the kind particularly used for the thickening of hair. It can be embodied either by a plurality of individual lock-like extension, i.e. a hair extension assembly for thickening hair, or it can be substantially shaped as a weft or layer, known as weft extension.[0003]As thickening of hair here and below it is intended the lengthening and the mass increasing of a human hair, through the application of hair extensions to receiving hairs.[0004]As hair extension it is intended a lock of hairs composed by a plurality of single human or artificial hairs, suitable to be handled as a single lengthening unit and to be applied to receiving hairs thank to a fixing element.[0005]Instead, with reference to the weft extension, it has a linear fixing element from which natural or artificial hairs perpendicularly branch, arranged according to a flat conf...
