Description

State of Technology of the Invention The Field of the Invention The present invention relates to hair cleansing, and more specifically to devices used for the treatment of pediculosis for the purpose of removing eggs from lice adhering to the hair. More specifically, the invention has a tooth or needle arrangement and composition that allows the comb to be used even on the scalp, which can have damage, injuries, lice, etc., and the tooth composition is hair. For the treatment of lice parasites, which keeps the efficiency of allowing the removal of lice and eggs from the hair more effectively, while making tooth production more economical compared to known devices and combs, without damaging the hair. Mention a new comb for.

Prior Art Description Pediculosis is a problem that affects countless individuals of all kinds of societies and represents a disability in the student population. This is because school-aged children are more likely to suffer from pediculosis when contacting friends at the educational institution they attend.

Head lice settle in the hair and lay well-known eggs, namely the pediculus humanus, the pediculus humanus, and similar species of eggs, more commonly known as lice.

Many combs, as well as many chemical compounds, have been developed for the treatment of this infection. These combs are intended to treat this by removing lice and eggs, so they do not cause the side effects that can occur when applying chemicals. There are various comb designs, including handles with multiple teeth or steel wires attached, and anything that attaches to this, especially the hair only between the adjacent teeth so that the egg is held between the teeth of the comb. Tooth separation has been studied to allow tight passage. For this reason, combing the entire patient's hair makes it possible to achieve the removal of as many eggs as possible.

One of the combs that most effectively achieved the goal of better egg removal is disclosed in Argentine Patent AR 03275 B1 and its US Patent No. 5,873,374. Both of them are owned by the owner of the present invention and, as specifically defined by claim, are clean combs having needles with irregularities on their peripheral surfaces, a handle and a plurality. Preferably including steel teeth, wires or needles, each needle has an end attached to the handle, an attacking end, and a peripheral surface, the contact end of each needle being rounded. Describes a clean comb with a tinged, pointed tip. According to the concept of these patents, the novelty of this comb to the prior art is that the perimeter of each needle is provided with irregularities designed to catch and drag eggs attached to the hair. The comb also features other features such as the distance between adjacent needles in the range of 50 μm to 100 μm, the total length of each needle in the range of 40-80 mm, and the useful length on the outside of the handle in the range of 20-60 mm. Have.

The feature of unevenness mentioned in the Argentine patent AR 03275 B1 and its US counterpart patent is preferably based on providing a spiral groove with a passage narrower than, for example, 4 mm. The unevenness can also be formed by circumferential grooves having a distance of 0.5 to 3 mm from each other, and these passages may have a depth of less than 0.2 mm.

In addition, this known comb is made of steel and has 10-100 needles, more precisely 33, and the abutting edges of the needles form a curved edge. It has other characteristics such as.

In addition, the teeth or needles have proximal ends held by the handle, and their distal ends, all aligned on the leading edge, do not damage the hair, and at the same time. It must be finely finished with a rounded, pointed, tapered shape to allow the hair to enter the space between the teeth or needles. This smooth finish, which can be done through various techniques, always results in a significant cost in the total cost of manufacturing the comb. As a result, these combs are not always accessible to all societies.

Known combs with teeth or fine needles ending at tapered ends to facilitate the entry of hair into the space between the teeth have proven to be efficient in some cases, but the patient or user. These combs cannot be used if the scalp is damaged for some reason, for example by weakening due to bedsores. This is because their tips further damage the scalp.

In view of the above, the inventors of the present invention have improved this type of comb, whether it is a conventional comb with needles or smooth teeth, or the above-mentioned patented comb with concavo-convex means. We set out to obtain a comb that can be used on damaged scalp and is more economical to manufacture without affecting the efficiency and effectiveness of removing blemishes and eggs as well as hair cleansing.

Brief Description of the Invention Therefore, an object of the present invention comprises a needle, tooth or wire capable of retaining, catching and dragging lice, eggs, and dirt without causing damage to the hair or scalp, said needle or Teeth are to provide a new comb for the treatment of lice parasites, which comprises at least two types of needles or teeth of different lengths.

Yet another object of the present invention is to ensure the effective removal of eggs and foreign matter adhering to the hair that easily enters the separation space between the teeth by the configuration of alternating lengths at the distal ends of the teeth. , Is to provide a new comb for the treatment of pediculosis.

Yet another object of the present invention is a comb for the treatment of scab, of the type comprising a gripping stalk with multiple protruding teeth, wherein the tooth has a proximal end held by the stalk. With a free distal end, the tooth is divided into a first plurality of teeth and a second plurality of teeth, the first plurality of teeth alternating with the second plurality of teeth. The first plurality of teeth are longer than the second plurality of teeth, so that the distal ends of the first plurality of teeth project beyond the distal ends of the second plurality of teeth. To provide a comb.

Yet another object of the present invention includes a gripping handle and a plurality of teeth of different alternating lengths, the teeth having continuous grooves intended to catch and drag lice and eggs present in the hair. Or to provide a comb for the treatment of pediculosis, which may be provided with concavo-convex means such as valleys.

Brief Description of Drawings For clarity and understanding of the subject matter of this invention, it is shown in several drawings. In the drawings, the invention is shown, by way of example only, in one of the preferred forms of expression.

The front of a comb for the treatment of pediculosis, both owned by Applicants and incorporated herein by reference, in accordance with Argentine Patent AR 03275 B1 and its US Correspondence Patent No. 5,873,374. It is a figure. It is a detailed enlarged view of the needle of the comb of FIG. 1 or the distal end of a tooth. Virtual needles or teeth that are comb needles or teeth, such as the comb in Figure 1, but with the distal or tapered ends removed to reduce their manufacturing costs, impairing their functional efficiency. It is a detailed enlarged view of. It is a front view of the preferred embodiment of the comb of this invention. It is a front view of another preferable embodiment of the comb of this invention.

Detailed Description of the Invention Here, with reference to the drawings, the invention may be of the type disclosed in Argentine patent AR 03275 B1 of the same inventors and applicants as the present invention, and in FIG. It can be seen that it consists of a comb for the treatment of pediculosis, as shown. This type of comb, generally designated by reference numeral 1, includes a gripping handle 2, which is fitted with a plurality of teeth 3 extending parallel to each other from the handle 2. Preferably, and without limitation for this invention, the plurality of teeth 3 retain a distance of 50 μm to 100 μm, which is a distance already proven to be efficient, for example, in the Argentine patented comb. In the case of the combs of the present invention, especially considering the variety of hair types in which this type of comb can be used, a separation of 50 μm to 200 μm is useful for both lice and egg removal and hair cleansing. Finding out, the range of distances between the teeth has been extended. Also preferably, the total length of the tooth or needle may be in the range of 40-80 mm and the useful length outside the handle may be in the range of 20-60 mm. In the above patent, the tooth or needle is provided with an uneven means for holding and dragging lice and eggs present on the hair. These means may be formed, among other things, by a plurality of continuous grooves or valleys defined on the surface of at least one longitudinal cross section of each of the teeth. In the cited patent, and as well shown in FIG. 2, the needle or the distal end 4 of the tooth 3 avoids damage to the scalp, and the hair enters the space 5 between the teeth 3. It is preferably terminated with a smooth conical shape to facilitate.

It should be noted that the concept of the present invention is a spiral or circumferential groove or valley pattern 6 along at least one longitudinal portion of each tooth, or any type of groove, gutter or valley pattern or design. Can be applied to the above-mentioned patented combs having. However, they are intended to form traps for catching and dragging lice, eggs, and foreign objects that adhere to the patient's or user's hair. However, the concept of the present invention can also be applied to combs such as the comb of FIG. 1 where the teeth or needles are smooth. The teeth may be separated from each other by, for example, a distance of 50 μm to 200 μm, and when a tooth having an uneven means such as a groove is used as described above, the circumferential groove is a distance of 0.5 mm to 4 mm from each other. The spiral groove may have a spiral space of 0.5 mm to 4 mm. Preferably, in either case, the spiral or circumferential column spacing should not be less than 0.2 mm.

For the tapered ends 4 of the prior art comb teeth 3, they impose work and time, as well as the use of special machinery, which ultimately represents significant costs. The tooth or needle 3 is mechanically cut from the roll wire to a defined length, and once cut, the tooth has one end, the end 4, in a rounded conical shape as shown in FIG. Taken into another machine that must be finished to. As explained, the cone is essential to allow the hair to enter the space between the teeth. If you want to avoid this finishing time, work and cost of the edge 4, you should simply leave the edge 4 unfinished, which is the tooth 3 as shown in FIG. 3 and with reference numeral 7. It is a virtual situation that leaves the edge of the tooth blunt. Of course, if the finish does not show the cutting edges resulting from the cutting of the wire, it may be used and no damage to the scalp would be expected. However, what cannot be achieved is that the hair enters the reduced space left between the teeth, for example 50 μm to 200 μm, or worse, 50 μm to 100 μm.

Although the present invention does not taper or conical the ends of the teeth and leaves them blunt, significantly reducing manufacturing costs, nonetheless, of the embodiments of the invention. According to one, it allows the hair to enter the space between the teeth, and according to another embodiment of the invention, it better protects the scalp and accurately addresses the above problems. To solve. Embodiments are referred to below with respect to FIGS. 4 and 5.

To identify embodiments of the invention, the reference numbers from 10 will be used to avoid confusion with the reference codes of the combs of FIGS. 1-3. According to a preferred embodiment of the invention shown in FIG. 4, the comb generally represented by reference numeral 10 includes a gripping handle 11 with a plurality of teeth or needles 12 protruding from the comb, wherein the plurality of teeth or needles 12 are present. , Each proximal end concealed and retained by the handle 11 and a free distal end generally indicated by reference numeral 13.

According to the concept of the present invention, the teeth 12 are divided into at least two groups, or more groups, so that the first plurality of teeth 14 and the second plurality of teeth 15 are formed, the first. The plurality of teeth 14 of 1 alternate with the second plurality of teeth 15, and the first plurality of teeth 14 are longer than the second plurality of teeth 15, so that the first plurality of teeth The distal end 16 of the tooth protrudes beyond the distal end 17 of the second plurality of teeth.

According to the embodiment of FIG. 4, the first plurality of teeth 14 and the second plurality of teeth 15 have a blunt distal end. In this way, the expensive work of machining and finishing the conical ends is avoided, but the fact that all the ends are not sharp is the hair, as could be the case with the teeth of FIG. Has no effect on entering the space between the teeth. In fact, the different distances of the ends 16 and 17 create a space between them, which facilitates the entry of hair. Although the blunt ends of both teeth 14 and 15 are left exposed and can be slightly finished with low cost polishing, preferably the blunt ends 16 damage the scalp due to their structure and shape. No material is coated with insert 18. The insert 18 is preferably rounded and can be formed of a variety of materials such as plastics, polymers, resins, ceramics, and countless low cost and easy to apply materials.

Combs can have a variable number of teeth or needles, but usually about 30 teeth are common. In this case, the first and second teeth will each contain 15 teeth. The longer teeth may be about 3 mm longer than the shorter teeth and will be staggered as shown. The needle, tooth or spike may be made of steel with a diameter of 1.25 mm and a spacing of approximately 0.1 mm or 0.2 mm.

As mentioned above, the invention may be applied to combs with perfectly smooth teeth, or combs that provide teeth with uneven means for holding and dragging lice and eggs present in the hair. The uneven means may be formed by a plurality of continuous grooves or valleys defined on the surface of at least one longitudinal cross section of each of the teeth. The grooves may extend circumferentially around the teeth and may be spaced by a distance of 0.5 mm to 4 mm. Alternatively, they may extend in a spiral shape around the tooth, the pitch of the spiral having dimensions of 0.5 mm to 4 mm.

In the embodiment of FIG. 5, the comb incorporates the same features as the invention shown in FIG. 4, except that the insert 18 of the longer first plurality of teeth 14 is not included. In this case, both the shorter and longer teeth have blunt edges. For this reason, the shorter tooth has a blunt end 17, and the end 16 of the longer tooth 14 is blunt or rounded enough to avoid damaging the scalp. It is cheaper than conical finishes, as well as blunt or rounded finishes.

If further reductions in manufacturing costs are still desired, the ends of the shorter teeth may not be finished by any of the aforementioned techniques and may be left intact after cutting. Because they do not come into contact with the scalp.

It is always more cost effective than traditional combs. Because a perfect finish with blunt or inserts is done only on the longest first multiple teeth, thereby a large path for hair between the longer teeth, hair cleansing and lice. And to preserve the features of the invention in defining the pathway leading to the space between the teeth performing the removal of the egg. The scalp is protected, whether it is blunt or with inserts. Especially in the latter case, the combs of the present invention have a pair of spaced teeth or needles to hold the eggs or clean the hair, and the distance between the needles is small as described above. Even, the new composition of the needle allows hair to get between the needles with a "gentle" end on the scalp, which makes it possible to get any scalp, even if the scalp is sick, injured or damaged. Allows the needle to be used with.

In this way, the present invention results in obtaining a comb at significantly lower manufacturing costs without compromising the efficiency and effectiveness of the comb.
