Definitions

  • the main object of this patent of invention is A RIGID COMB HAVING MICROTEXTURIZED-TIP TEETH FOR HAIR CLEANING, especially designed to effectively catch, hold and remove lice and nits gripped on to the hair.
  • this patent of invention relates to a novel rigid comb of the kind used to conduct the aforementioned hair cleaning process through the sweeping action of very rigid teeth.
  • This cleaning task is aimed to fight Pediculosis, a skin injury produced by the bite of lice, very ravenous parasites found only on humans, which die soon outside their feeding environment.
  • the best solution consists in finding and carefully removing lice and nits so as to root out the infestation and avoid its spread.
  • nits are the lice's eggs that live on the hair, close to the scalp, feeding on the blood stream ever since their birth. They are smaller than lice and stick to the hair thanks to a glue used by the female louse when laying the nit.
  • US patent 4,612,945 can be mentioned, which refers to a lice and nits removing comb.
  • a cross section view of the comb shows long triangular teeth the thickness of which decreases towards the distal ends, so that the distance between two adjacent teeth is shorter near the handle and widens towards the free ends.
  • the teeth are arranged so that their longitudinal axes are parallel and in alternate planes one after the other.
  • These teeth have a useful or active length of 9 mm or less, and stand out because their free or distal end sections are hook shaped, thus ensuring that lice and nits will be caught by the comb.
  • a further attempt is being made to give a special treatment to the outside surface of each tooth, with the purpose of granting a certain surface roughness that may help catch and hold these insects during the combing process.
  • a rough surface is a basic feature that does not constitute any novelty at all, as all surfaces have a certain degree of roughness which can be determined and measured. As all surfaces are rough, all the combs referred to are rough.
  • canalization is also the possibility to define such canalization as a series of circumferential grooves separated by .5 mm to .3 mm.
  • the rigid comb referred to herein suggests a new structural and functional solution that outperforms the above-mentioned patents.
  • the result is a comb fitted with teeth designed to glide gently through the hair, avoiding unwanted electrostatic charges and tangles that affect the sweeping action and prevent the distal ends from acting on the hair base that harbors nits.
  • microtexturing grants an abrasive power that keeps the insects trapped during the sweeping process.
  • microtexturized surface does not cause any variation in the distance between adjacent teeth, thus avoiding the risk that the trapped insect might get loose.
  • each tooth making up the rigid comb referred to in this invention has an outside surface defined as per two clearly distinguished sections, namely:
  • the former section has a (lower) degree of roughness to ensure that the hair can run gently as the comb works its way through the hair, preventing electrostatic charge and tangles.
  • This section has been particularly designed to allow easy sweeping and combing.
  • the distal section's distinctive feature is its microtextured surface, achieved by high-speed glass microfibers blasting. Given its roughness degree, this microtexturing gives the comb the ability to hold the trapped insects, allowing the nits to come off the scalp.
  • This invention also contemplates the possibility of attaining such microtexturing by sand blasting, that is to say, by using fine sand grains, thus achieving a result similar to the one mentioned before.
  • This surface microtexturing is done on the distal section where each tooth tip acts on the hair base next to the scalp, where nits are usually harbored due to its proximity to the food source, which is the blood sucked by lice at birth.
  • the invention also contemplates the possibility of applying such microtexturing on part of the cylindrical surface of said distal section.
  • the main object of this patent of invention is A RIGID COMB HAVING MICROTEXTURIZED-TIP TEETH FOR HAIR CLEANING, of the type made up of a handle and a number of sweeping teeth projecting therefrom, thus forming a rigid set of great mechanical strength, where said teeth are aligned one after the other, with a minimal separation between them, and emerging from the handle to a length considerably greater than the anchorage length.
  • the novelty lies in the fact that the teeth have a proximal section, extending from their anchorage inside the handle to a point of their total length outside the handle, where a distal section begins and extends up to the free tip, and this section's surface roughness is different from that of the proximal section.
  • the teeth's proximal section has an even circular cross section.
  • the cross section of the teeth's distal section shows a decreasing circle towards the free end, which turns into a sharp rounded tip.
  • Another key feature is that part of the outside surface of the distal section of each tooth is microtexturized. Another key feature is that all the outside surface of the distal section of each tooth is microtexturized.
  • Figures 1 to 7 are microphotographies of six teeth belonging to the comb subject matter of this patent of invention.
  • Figure 8 is a perspective view schematically representing a rigid comb complying with the construction terms set forth in this invention.
  • Figure 9 is a blown-up cross section view as per drawing IX-IX indicated in figure 10.
  • Figure 10 is a frontal top view showing a partial detail of the inner face of the teeth-bearing handle.
  • Figure 11 is a blown-up detail showing a variation to this invention, where the distal section of the tooth is partially microtexturized.
  • Figures 1 to 7 represent photomicrographys of six metal teeth complying with the conditions set forth in this invention.
  • the data appearing at the foot of each microphotography indicate, from left to right, the white cement value in the scale, the work voltage, the amplification expressed in powers of ten and an identification number.
  • FIGS 1 and 2 show the section of the tooth next to the handle, while figures 3 to 7 represent the distal sections of the same teeth.
  • FIG. 8 A look at Figures 8, 9, 10 and 11 shows that the comb subject matter of the invention belongs to the type of combs having a rigid handle (M) made of injected plastic material, from which a number of coinjected teeth (D) having a special structure are projected.
  • M rigid handle
  • D coinjected teeth
  • the teeth (D) have circular cross section and each of them can be defined as a rigid body anchored to the support handle (M).
  • Each tooth has a proximal section (D1), the surface roughness of which does not affect combing. This section originates in its coinjection with the rest of the handle (M) and projects outwards in a short length. Then, the distal section (D2) begins, the cross section of which gradually decreases towards its free end, which is sharp and rounded.
  • each tooth can have a total length (lt) of about 60 mm, and an active length (la) of about 40 mm, determined by the length protruding from the handle.
  • the higher roughness distal section (D2) can have a total length (Lr) of about 20 mm.
  • Figure 11 represents the case where each tooth of the invented comb has a partly microtexturized distal section (D2).
