Definitions

  • the present invention in some embodiments thereof, relates to an easy-cleaning folding comb for removing lice or nits from the hair.
  • Head lice Pediculus capitis
  • Head lice infestation (pediculosis) is a common problem, particularly among school-aged children. Signs of infestation include small red marks on the scalp caused by the lice biting, and acute itching. In order to effectively treat pediculosis, it is important not only to eradicate the adult lice, but also to remove any unhatched eggs, or nits, which are deposited by adult females on the head. Although insecticidal shampoos will help rid the scalp of adult lice, it is not fully effective. Therefore, most treatments also include manual removal of lice and nits. It is recommended that this is carried out for at least ten days.
  • Removal can be accomplished by using fingernails, tweezers, or preferably by using specially developed lice combs having very close spacing between the teeth of die comb. Lice combs with different teeth sizes, shapes and roughness patterns are known in the art. To avoid recontamination, the extracted lice must be removed from the comb. However, the density of the teeth of the comb required to remove the lice, hampers cleaning efforts.
  • US Patent 11,445,793 teaches a lice comb comprising a first member attached to a second member via a perpendicular hinge.
  • the position of the hinge in the lice comb taught in US Patent 11,445,793 does not allow for the teeth to be efficiently cleaned. Since one hand is required to grip the comb at the handle and ensure that the two members stay apart during cleaning, the ability to pry open the teeth and free trapped lice and eggs is hindered.
  • Additional background art includes US11445793, US5318051, GB2396104, CN203137397, CN103126269. CN202476777, US 1651746, IL219899. US2021212434. US5873374, US2002078972, CN Design 303686073, USD8.54244 and USD770093.
  • a foldable lice comb for extracting lice or nits from hair or scalp
  • the comb comprising a first member hingedly attached to a second member via a hinge; both the first member and the second member comprise a hand-held portion and a parallel series of teeth which extend outwardly from a teeth-retaining end of the hand-held portion; and the hinge being parallel to the series of teeth and being configured to allow the first member to fold towards the second member to acquire a folded configuration and to fold away from the second member to acquire an unfolded configuration, the parallel series of teeth being spaced and positioned such that when the comb acquires the folded configuration, the parallel series of teeth of the first member interlace with the parallel series of teeth of the second member to form a comb configured to remove lice or nits from hair or scalp, whereas when the comb acquires the unfolded configuration, the teeth of both the members are in a contiguous orientation.
  • the hinge comprises a spring hinge, a pivot hinge, a snap hinge and a butt hinge.
  • a spacing between the teeth of the first member is equivalent to a spacing between the teeth of the second member.
  • the teeth of the first member and the second member are evenly spaced.
  • the teeth of the first member and the second member are tapered.
  • the teeth of the first member and the second member are grooved.
  • the teeth of the first member and the second member are helically grooved.
  • the teeth of the first member and the second member are fabricated from stainless steel.
  • the comb further comprises a securing mechanism for securing the comb in its folded configuration.
  • a securing mechanism for securing the comb in its folded configuration.
  • an outer edge of the hand-held portion of each of the first member and the second member is rounded.
  • the hand-held portion of the first member is of the same shape and dimensions as the hand-held portion of the second member, thereby ensuring that when the comb is in its folded configuration, the hand-held portions sit directly on one another to form a single member.
  • the hinge further comprises a stoppage mechanism that prevents opening further than 180 degrees in the unfolded configuration.
  • the hand-held portion of each member comprises a front piece facing exteriorly when the comb is in the folded configuration and a back piece facing interiorly when the comb is in the folded configuration, the parallel series of teeth extend outwardly from a teeth-retaining end of the back piece of the hand-held portion.
  • FIG. 1 is a lice comb depicted in an unfolded configuration in accordance with some exemplary embodiments of the invention.
  • the exterior facing surface of the lice comb is viewed from above.
  • FIG. 2 is a lice comb depicted in a folded configuration in accordance with some exemplary embodiments of the invention.
  • FIG. 3 shows the teeth arrangement of the lice comb of Figure 1 when in a folded configuration, as viewed from below.
  • FIG. 4 is a lice comb depicted in a folded configuration with an opening mechanism.
  • FIG. 5A is a lice comb depicted in a folded configuration in accordance with some exemplary embodiments of the invention.
  • FIG. 5B is a cross sectional view of the lice comb (and magnification thereof) illustrating a securing mechanism which secures the comb in its folded configuration.
  • FIG. 6 is a lice comb depicted in an unfolded configuration in accordance with some exemplary embodiments of the invention.
  • the interior facing surface of the lice comb is viewed from above.
  • FIG. 7 depicts exemplary components of a lice comb in accordance with some exemplary embodiments of the invention.
  • the present invention in some embodiments thereof, relates to an easy-cleaning folding comb for removing lice or nits from the hair.
  • the present inventors have now conceived of a comb which is effective in the removal of lice and nits from hair whilst still being capable of being efficiently and effectively cleaned of captured matter. Effective cleaning is of ultimate importance as it prevents reinfestation.
  • the comb comprises two members hingedly attached to one another, each member with a series of teeth. In the folded position, the two sets of teeth are interlaced forming a single row of teeth. The positioning of the teeth in the folded configuration allows for efficient removal of lice and nits. In the unfolded configuration, the gap between successive teeth of the series allows for easy and efficient cleaning, without the need to distort the teeth of the comb.
  • the hinge is in parallel to the series of teeth, allowing the two members to move towards one another and acquire the folded configuration or to move away from one another and to acquire the unfolded configuration (analogous to the opening and closing of a book).
  • This configuration is advantageous since it allows full extension of the comb in its unfolded configuration.
  • the teeth of both members, whilst separated are parallel with one another, forming a single row and being on the same plane. This allows for easy removal of trapped matter.
  • location of the hinge at a position distant from the hand-held portion of the comb allows for an ergonomic design of the hand-held portion without interference from the hinge.
  • FIG. 1 is a top view of lice comb 10 comprising two body members 12 and 14, each having a hand-held portion 16 and 18 and series of teeth 20 and 22.
  • the teeth in each of the series of teeth 20 and 22 are positioned parallel to one another.
  • the teeth of the series 20 and 22 are elongated, each extending from a teeth-retaining end 24 and 26 of hand-held portion 16 and 18.
  • the number of teeth in series 20 is equal to the number of teeth in series 22.
  • Each series may have between 12 and 20 teeth. In one embodiment, each series has 16 teeth.
  • body members 12 and 14 are shown with a promotional branding or a design element 58. Such advertising or artwork can applied using techniques known in the art. It will be appreciated that this is an optional feature and may or may not be applied to any part of the comb.
  • Hand-held portion 16 and 18 of body member 12 and 14 may be of any shape.
  • the hand-held portion is of a rounded shape, allowing for easy grip of comb 10.
  • Handheld portion 16 and 18 may be fabricated from materials including metal (e.g. stainless steel), plastic, polymer (molded polymer) etc.
  • the hand-held portion is ergonomically designed for easy grip.
  • the hand-held portions 16 and 18 are typically of a height not greater than two times or three times the height of the teeth 20 and 22.
  • 16 and 18 are typically of a height not greater than the height of the teeth 20 and 22.
  • lice comb 10 is devoid of an extended handle.
  • Hand-held portion 16 and 18 are typically located above the longitudinal axis of teeth 20 and 22 (i.e. along the same axis), such that upon gripping lice comb 10, the hand of the user is positioned above the teeth 20 or 22 and not on the side of the teeth 20 or 22.
  • the spacing between the teeth of the first member 12 is equivalent to the spacing between the teeth of the second member 14. Additionally, the teeth of the first member 12 and the second member 14 are evenly spaced.
  • each tooth has a length of from about 20 mm to about 90 mm (for example about 40 mm). Each tooth has a diameter from about 0.75 mm to 1 .5 mm (e.g. about 1.15 mm).
  • the teeth of series 20 and 22 are evenly spaced. The teeth of series 20 have the same spacing between the teeth of series 22.
  • the space 30 between each tooth of series 20 and 22 at its minimum is equivalent to the width of the tooth 34.
  • there is an additional gap which is typically 2 times a target gap 32.
  • the target gap 32 may be defined as the desired gap between the active portions of adjacent teeth when the comb is in the closed position: where,
  • G ATC target gap between the active portion of adjacent teeth when the apparatus is in the closed position (34).
  • Target gap 32 is illustrated in FIG. 2.
  • the teeth comprised in the teeth series 20 and 22 can be made of a metal, for example stainless steel, with a peripheral surface either smooth or grooved (e.g. helically grooved). In another embodiment, the teeth of series 20 and 22 may be tapered.
  • Hinge 28 defines a central axis and connects first body member 12 to second body member 14 allowing the two members to open and close about a central axis.
  • the lice comb of this aspect of the present invention is configured as in a book, the spine of the book analogous to the hinge, and the open pages on one side of the spine analogous to the first body member and the open pages on the other side of the spine analogous to the second body member.
  • FIG. 1 illustrates the exterior facing side of lice comb 10 in an open configuration. In this configuration series of teeth 20 are in a contiguous orientation with respect to series of teeth 22. The contiguous orientation of the teeth allows for the teeth to be cleaned with a single swipe under running water.
  • FIG. 7 illustrates components of an exemplary hinge according to embodiments of the invention.
  • hinge pin 46 passes through the perforations in the knuckles 48. 50 and 52 of the first member 12 and through the perforations in the knuckles 54 and 56 of the second member 14 to connect the two body members. ’Thus, the hinge pin 46 and knuckles 48, 50, 52, 54 and 56 form the hinge 28.
  • Any type of hinge is conceived by the present inventors including but not limited to an external hinge, an internal hinge, a spring hinge, a pivot hinge, a snap hinge and a butt hinge.
  • the hinge is configured to prevent opening further than 180 degrees in the unfolded configuration.
  • the comb 10 comprises an additional stoppage mechanism which prevents the comb from opening beyond 180 degrees in the unfolded configuration.
  • FIG. 2 illustrates the lice comb 10 in a closed configuration.
  • First body member 12 sits directly on second body member 14.
  • Hand-held portion 16 may be of essentially the identical shape and dimensions as hand-held portion 18.
  • the first series of teeth 20 interlace with the second series of teeth 22 to form a comb configured to effectively remove lice or nits from hair or scalp.
  • FIG. 3 illustrates how teeth A, C, E, G, I, K, M, O, Q, S, U, W, Y, AA, CC and EE of series 22 interlace with teeth, B, D, F, H, J, L, N, P, R, T, V, X, Z, BB, DD of series 20 to form a comb having a single series 36 of parallel teeth.
  • the single series is a row.
  • Lice comb 10 may comprise a securing mechanism for securing the comb in its folded configuration.
  • the securing mechanism may be such that the securing mechanism can be overcome by force (e.g. prising hand-held portion 16 away from hand-held portion 18). In one embodiment, the securing mechanism is hidden when lice comb 10 is folded.
