BRIEF DESCRIPTION OF THE DRAWINGS
FIGS. 1 to 3 illustrate a hair extension removal tool according to an embodiment of the present invention.



DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
In a common hair extension technique, strands of supplemental hair are attached to strands of the subject's own hair by a bonding material. To remove the supplemental hair, the bonding material must be sufficiently dissolved so that the supplemental hair is separated from the subject's own hair.
A hair extension removal tool according to embodiments of the present invention is described below with reference to FIGS. 1 to 3. As shown in FIG. 1, the hair extension removal tool 1 is generally shaped like a pair of pliers formed of two elongated members 11 and 21 pivotally jointed together at a pivot point 31. The distal ends of the two elongated members form two jaws 12 and 22 of the tool that can open and close when the elongated members 11 and 21 pivot with respect to each other. A body 13 is attached to the first elongated member 11 and forms the main part of a handle of the tool which is held in a user's hand when the tool is used. The body 13 may have any suitable exterior shape, but it is preferably designed to fit comfortably in the hand of the user.
As shown in FIG. 2, a container 41 is housed within the body 13 to contain a solvent suitable for dissolving the bonding material used in the hair extension. The container 41 is preferably a separate container, or it may also be formed by the inner surface of the body 13 itself. An opening is provided at the end of the body 13 with a lid 14 for re-supplying the solvent and/or replacing the container. A tubing 42 in fluid communication with the container 41 extends from the container to an opening 43 on the inside surface of the first (lower) jaw 12. Passages (not shown) are provided in the body 13, the second elongated member 21 and the first elongated member 11 to allow the tubing 42 to extend therethrough. Alternatively, the tubing 42 and opening 43 may be located on the inside surface of the second (upper) jaw 22, or on both jaws. A pressing lever 15 is pivotally attached to the body 13 to control an application mechanism (e.g. a pump) 45 of the container 41 disposed inside the body. When the lever 15 is pressed, the application mechanism (pump) 45 is activated to eject an amount of solvent in the container 41 through the tubing 42 and the opening 43 in the form of a fine stream or spray. As an alternative to the lever 15, a push button, finger trigger or other type of activation mechanism may be used. As shown in FIG. 2, the pump 45 may include a spring-biased plunger 45a which is pushed by the lever (the activation mechanism) 15. Application mechanisms for ejecting a liquid from a container are well known in the field of spray bottle design. Any suitable designed may be used for the application mechanism 45 and its structure is only schematically illustrated in FIG. 2 and further details are omitted here.
Mating patterns of fine grooves are preferably formed on the inside surfaces of the jaws to more effectively engage the hair being worked on. The jaws are shaped such that when the tool is in a closed state, the inside surfaces of the first and second jaws come into close proximity with each other but do not come into actual contact. This eliminates a common problem of hair breakage in conventional hair extension removal tools. In addition, as schematically illustrated in FIG. 3, one or more longitudinal channels 121 are formed on the inside surface of the first (lower) jaw 12. When the tool is in use, the solvent may pool in the channel(s) 121. Advantages of the pooling of solvent in the channel(s) include reducing in the amount of solvent needed, improving in the dissolving process as solvent is pooled at the site of the bonding material, and preventing the solvent from running down the hair which reduces dry hair and brittleness. In operation, a strand of the hair extension is held with one hand of the user so that the segment where the supplemental hair is jointed to the subject's own hair is located within the jaws of the removal tool, which is held in another hand of the user. With the jaws either open or closed, the lever 15 is pressed, for example, with the thumb or index finger of the user, to eject an appropriate amount of the solvent from the container 41 through the tubing 42 which has its end located near the opening 43 on an inside surface of a jaw. The solvent is thus applied to the joined segment of the hair extension where the bonding material is present. Excess solvent, if present, will pool in the channel(s) 121 in the lower jaw 12. The user then applies pressure to the joined segment of the hair extension with the jaws of the tool to weaken the attachment, while repeatedly applying the solvent when appropriate, until the bonding material is sufficiently dissolved and the supplemental hair is detached and removed from the subject's own hair. Using the hair removal tool, the hair extension is removed one or more strands at a time.
It will be apparent to those skilled in the art that various modification and variations can be made in the hair extension removal tool of the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention cover modifications and variations that come within the scope of the appended claims and their equivalents.
