Definitions

  • the invention relates to a device for hair supplementation with a plurality of hairs, which are aligned at their upper ends in a main direction parallel to each other and embedded and anchored in a plastic matrix, with a transverse to the main direction carrier tape, on the front side of the plastic matrix and an adhesive layer covering the back of the carrier tape adapted to secure the carrier tape to natural hair of a wearer of the hair supplementing device.
  • the number of natural hair of the wearer can be increased. It is also possible to extend the natural hair of the wearer. In this context, one speaks of a hair extension. Furthermore, with the hair of the device for hair supplementing color contrasts against the natural hair of their wearer can be made.
  • An apparatus for hair supplement with the features of the type described above, which corresponds to the preamble of independent claim 1, is known from DE 20 2005 010 845 U1 known.
  • a plurality of hairs attached to a carrier tape that is also designed as an adhesive tape to attach the device to natural hair of a wearer.
  • the parallel running hairs are glued over the entire width on one side to the carrier tape.
  • the hairs are where they are glued to the carrier tape, anti-hygroscopic sealed.
  • Such a seal provides hairs made of human hair to suppress their hygroscopic properties, due to which the risk of detachment of the hair from their bonding with the carrier tape due to the influence of moisture.
  • a plastic matrix is formed, in which the individual hairs are embedded and anchored with their upper ends.
  • a matt and translucent cover layer can be provided so that the plastic matrix of the device remains optically inconspicuous.
  • the adhesive tape formed as a carrier tape has on its the plastic matrix, in which the hair is anchored, the back facing away an adhesive layer for sticking to the natural hair of the wearer. This adhesive layer, like the plastic matrix, extends over the entire surface of the carrier tape.
  • From the EP 2 242 386 B1 is a hair band with a strip-shaped support structure and with several hairs known which protrude in a direction transverse to the main extension direction of the support structure main direction of the support structure. Ends of the hair fixed to the support structure pass through an elastic film and are glued to the back of the film. In this case, the pierced by the elastic film hair on the back of the film are cut to a few millimeters, so they do not lie on top of each other. and fixed to the support structure exclusively by gluing to the film. On the back of the film embedded in the adhesive upper ends of the hair are covered with a cover layer. At the back of the entire support structure is an adhesive layer provided with a removable protective layer.
  • the adhesive layer itself may also be removable in order to replace it if, for example, it has become inactive due to the action of hair care or washing detergents.
  • This known hair band is adhered to hair of a wearer, it is particularly inconspicuous, because his hair from the slide stand out individually, which gives the impression of natural scalp.
  • the production of the known hair band is much more complicated than that of the device for hair extension according to the DE 20 2005 010 845 U1 ,
  • the invention has for its object to provide a device for hair supplementation, which is inexpensive to produce and yet remains inconspicuous, even if it is attached by a layman as the wearer of the device itself to his natural hair.
  • a device for hair supplementation with a plurality of hairs which are aligned at their upper ends in a main direction parallel to each other and embedded and anchored in a plastic matrix, with a transverse to the main direction carrier tape, on whose front side the plastic matrix is attached, and with an adhesive layer covering the backside of the carrier tape adapted to secure the carrier tape to natural hairs of a wearer of the hair supplement device, the plastic matrix is disposed at an upper edge of the carrier tape, the plastic matrix extending in the main direction by no more than half of a width of the carrier tape extends and wherein the hair below the plastic matrix in the main direction across the carrier tape away.
  • the invention is based on the idea of making the plastic matrix just as wide as the carrier tape and the adhesive layer. Rather, while the adhesive layer is further formed so as to cover, ie at least substantially cover, the back of the carrier tape, and the carrier tape maintains a certain width to ensure the handleability of the device in its mounting and over a certain length to the natural To fix hair of its wearer.
  • the plastic matrix in which the hair of the device for hair supplement are anchored, but is significantly narrower than the carrier tape held, and it is placed at its upper edge. This has the consequence that the from the Plastic matrix emerging and over the carrier tape away extending hairs of the device for hair supplement cover the carrier tape, ie make visually invisible.
  • the visual impression of the hair of the hair replenishment device running across the carrier tape from the plastic matrix is that of natural hair of the wearer. From the visual impression of the natural hair of the wearer deviates in the inventive device only from the narrow plastic matrix from. Due to their small width, the plastic matrix in the device for hair supplement according to the invention is much less conspicuous and virtually unnoticeable compared to the prior art. This is especially true when the plastic matrix in the main direction extends over not more than a third of the width of the narrower itself held carrier tape.
  • the hair running underneath the plastic matrix in the main direction over the carrier band can be adhesively bonded on one side to the carrier band.
  • the plastic matrix is adhered to the upper edge of the carrier tape, it can also be glued to the carrier tape on one side.
  • this one-sided bonding is not crucial for the anchoring of the upper ends of the hair in the device according to the invention.
  • it is also harmless that the hair where they are above the carrier tape are exposed to external moisture and solve, for example, due to changing moisture content and correspondingly changing diameter of the individual hair from their one-sided bonding with the carrier tape. They remain anchored in the plastic matrix.
  • the hair running underneath the plastic matrix in the main direction over the carrier tape can therefore also run freely over the carrier tape from the outset, ie. H. without being glued to one side with this.
  • the plastic matrix may be provided on its side facing away from the carrier tape with a matte surface or a matte cover, through which it is particularly inconspicuous. This is also helped if the plastic matrix and its cover possibly present on its side facing away from the carrier tape is transparent or translucent up to the hair.
  • the plastic matrix may extend in the main direction over 2 to 6 mm or in particular over 2.5 to 4 mm.
  • the resulting length of embedding of the upper ends of the hair in the plastic matrix is sufficient for their anchorage. This is true for the lower limit values of the width of the plastic matrix of about 2 mm and in particular for a width of about 3 mm, with which the plastic matrix remains optically still very inconspicuous.
  • the hair can end in the main direction with the plastic matrix. This is synonymous with the fact that the hair is also cut off when cutting the plastic matrix to its small width. This is not precluded by the fact that the cut surfaces of the hair are provided with an anti-hygroscopic seal, so that they are sealed anti-hygroscopic like the rest of the embedded in the plastic matrix upper ends.
  • the plastic matrix may extend to the ends of the carrier tape, so that no end of the carrier tape not covered by the plastic matrix or the hairs anchored therein is exposed.
  • a length of the carrier tape between its ends may be in particular 10 mm to 26 mm or 14 mm to 20 mm.
  • the external plastic matrix is also comparatively short. In particular, this applies when the carrier tape is folded around a strand of the natural hair of the wearer of the device for hair supplement to embed the hair of the strand in the adhesive of the then pressed against each other parts of the adhesive layer. In this use, the visible length of the plastic matrix reduces to half the width transverse to the main direction.
  • the carrier tape and the plastic matrix can have a predetermined bending point, in particular at half the length of the carrier tape, transversely to the main direction. Specifically, at the predetermined bending point, a material cross-section of the carrier tape and / or the plastic matrix can be reduced by at least 10% in relation to the regions adjacent to the main direction.
  • the plastic matrix can also be interrupted in the region of the predetermined bending point.
  • the adhesive layer may be covered on its side facing away from the carrier tape with a removable protective film. It is also possible that the adhesive layer is adhesively bonded to a common carrier in addition to the adhesive layers of other devices for hair extension. If it is removed from this carrier, then the same adhesive layer is exposed. If, on the other hand, a separate protective film is provided for the adhesive layer of the individual device for hair supplementation, it can also be detachable be glued to a support for several such devices. In addition, such a protective film can be subdivided halfway along the carrier tape transversely to the main direction into two sections, which can be detached individually from the adhesive layer when attaching the device for hair supplementation. In addition, this subdivision of the protective film also facilitates the central folding of the carrier tape with the plastic matrix.
  • transverse to the main direction is here not only referred to an exactly vertical direction but in each direction, which has an essential component perpendicular to the main direction.
  • the plastic matrix may be constructed in layers of different plastics by, for example, coating a substrate with an adhesive which adheres the hair to the substrate and then covering the hair with further adhesive or plastic in one or more steps. This results in a layer structure of the plastic matrix.
  • flat material such as, for example, a layer of silk gauze for matting or the like, can be embedded in this layer structure. With the substrate, the plastic matrix can then be glued to its desired width along the main direction on the carrier tape after it has been cut.
  • the hairs of the device according to the invention for hair extension may be real hairs which are then aligned in the direction of their natural course from the hair root to the hair tip in the main direction and thus run away from the plastic matrix. Hair may also be synthetic hair, especially high quality synthetic hair based on horn.
  • the illustrated device 1 has a carrier tape 2. On the front side of the carrier tape 2, a plastic matrix 3 is attached. The plastic matrix 3 does not extend over the entire width 4 of the carrier tape but only over the upper, adjacent to its upper edge 5 third. In the plastic matrix 3 hair 6 are embedded. The hairs 6 are parallel to each other and side by side in a main direction 7 Fig. 1 In fact, the number of hairs 6 shown is less than the actual number of hairs in the device 1. In fact, the hairs 6 exiting the plastic matrix 3 substantially completely cover the underlying two-thirds of the carrier tape 2. The optical appearance of the device 1 is characterized - apart from the narrow plastic matrix 3 - characterized only by the hair 6.
  • the plastic matrix 3 On its side facing away from the carrier tape 2 outside 8, the plastic matrix 3 is dull and can be provided with a matte cover. In addition, the plastic matrix 3 is translucent up to the hair 6 embedded therein. Thus, the plastic matrix 3, in particular because of their small width in the main direction 7 optically inconspicuous. Below the plastic matrix 3, the hair 6 can be glued on one side to the carrier tape 2. However, this does not have to be the case. In the middle of their extension transverse to the main direction 7, the carrier tape 2 and the plastic matrix 3 are provided with a recess 9 in the region of the upper edge 5. This recess 9 forms a predetermined bending point 10 for the carrier tape 2 with the plastic matrix 3.
  • Fig. 2 shows the device 1 in a side view.
  • an adhesive layer 11 can be seen on the back of the carrier tape 2, which serves to attach the device to natural hair of a wearer of the device 1 for hair extension.
  • the adhesive layer 1 extends over the entire width 4 of the carrier tape second Fig. 2 also shows how the hair 6 below the plastic matrix 3 extend over the carrier tape 2 away.
  • Fig. 3 shows the use of the device 1, ie its attachment to natural hair 12 of a wearer of the device 1.
  • the device 1 or its carrier tape 2 together with the plastic matrix 3 around the predetermined buckling point 10 around folded or folded, so that the natural hair between 12 opposing portions 13 and 14 of the adhesive layer 11 are brought and embedded there between the connecting regions 13 and 14.
  • the adhesive layer 11 is typically covered with a releasable protective film (not shown) prior to use of the device 1.
