Rigid comb having microtexturized-tip teeth for hair cleaning

Abstract

A comb made up of a handle wherefrom a number of sweeping teeth are projected, thus forming a rigid set of high mechanical strength, where the teeth are aligned one after the other with a minimal separation in between to define the comb front, keeping the anchorage section of each tooth within the handle body, and projecting out of the handle in a length considerably greater than the anchorage length. The teeth have a proximal section starting 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 end, and where the surface roughness of the former section is different from that of the distal section, which is microtexturized.

Description

BACKGROUND OF THE INVENTION [0001] 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. [0002] Basically, 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. [0003] 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. [0004] When Pediculosis is detected, the best solution consists in finding and carefully removing lice and nits so as to root out the infestation and avoid its spread. [0005] In the old days, the method used was either to nearly shave the head or wash the hair with abundant soapy hot water mixed with alcohol, vinegar and the like. [0006] Today's rigid combs are th...

AI Technical Summary

Benefits of technology

[0036] Firstly, 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.

[0037] Furthermore, a minimal separation between adjacent teeth has been achieved, which ensures lice and nits catching without affecting the necessary comb movement.

[0040] Likewise, said microtexturing grants an abrasive power that keeps the insects trapped during the sweeping process.

[0041] In addition, such microtexturized surface does not cause any variation in the distance between adjacent teeth, thus avoiding the risk that the trapped insect might get loose. Roughness Concept

[0063] It can be noted that 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.

Problems solved by technology

However, the results can be said not to have been entirely satisfactory, as the spacing between the distal ends is rather big, thus affecting the gadget's ability to catch and hold lice, particularly nits.

It must also be noted that such triangular section gives rise to cutting edges that tend to damage the hair, thus causing an unwanted effect.

It has been verified that this solution is not really effective, as the teeth are short and in many cases their hook-shaped free ends do not manage to make contact with the scalp.

Likewise, the spacing between the teeth is too big, which makes it impossible to remove nits, as they do not reach the area where nits are usually glued, neither can teeth catch them when nits lie on the hair.

The problem that arises with this type of structural solution lies in the need to properly determine the distance ratio between the teeth so as not to affect the sweeping action, because if the spacing is very small, it will be highly difficult for the teeth to run between the strands of hair up to the base, where nits are glued.

It has also been verified that this type of surface treatment on teeth causes the hair to gain electrostatic charge and get entangled when it reaches the handle area.
