The hairbrush includes a field of bristles where bristle height is substantially random and substantially independent of position on the hairbrush. Within the bristle field, the bristle width and/or the bristle material may vary between bristles - for example, substantially randomly with respect to position and/or in a manner that is correlated with bristle height.

Description

Hair brush, method of using same and method of making same

The present invention relates to a hairbrush, a method of using the same, and a method of manufacturing the same.

Background of the invention

Embodiments of the present invention are directed to surprising findings, including (i) the ability to fabricate a hairbrush that has a non-uniform, irregular nature defined by the "finish end" surface defined by the end of the brush ( For example, having a semi-random or random nature) and (ii) the hairbrush is useful for "reducing the pain of the hair." It has been found from inter-disciplinary trials that, under the supervision of the inventors, it has been found that this hairbrush significantly reduces the time required to comb the hair (e.g., longer hair) and significantly reduces the pain and discomfort associated with combing the hair, even It can be helpful for wet hair and/or wet hair that has not been conditioned with conditioner.

The present invention has not been deliberately related to any particular principle, noting that the length of the human hair is generally not uniform and is usually distributed in some semi-random or random manner, despite the fact that the head or some of its regions are averaged. Hair length may be the same. The inventors have experienced that the hairbrush provided by embodiments of the present invention can help reduce pain and/or comb the hair because the length of the bristles itself is random on the bristles of the hairbrush. / or accompanying machine changes, this approach at least partially simulates a random or semi-random variation of hair length.

Thus, according to the description of this principle, the hairbrush and, in particular, the "bristle tail" surface defined by the distal end of the tip have some degree of turbulence or entropy and thus are "compatible" with the hair to be combed. . In addition, the hairbrush geometry (as opposed to the case where the length of the bristles is fixed or varies in a certain "regular" manner) reduces the amount of tension in any single position for the tension or tension associated with dispersing the hair. help.

In certain embodiments, the hairbrush combs the hair in a "low pain" or even painless manner and is useful to eliminate or reduce the amount of hair rolled up or entangled during carding.

According to an embodiment of the present invention, a hair brush is specifically provided, the hairbrush comprising a bristles holding surface and at least one bristles of at least 100 bristles, the bristles being individually disposed to the bristles holding surface so that the bristles are bristled The height varies in a substantially random manner and is substantially independent of the position of the bristles on the bristles holding surface, the bristle regions providing the following features: (i) a height feature such that at least five different heights are produced; (ii) width characteristics such that each bristles have a width of at least 0.5 mm; and (iii) bristles end features such that at least 60% of the bristles have rounded ends.

Detailed description of the embodiments of the present invention

1A-1B show a hairbrush in accordance with some embodiments of the present invention. The hairbrush 500 includes a brush body 510 and a plurality of bristle regions 540 disposed on one of the brush body holding surfaces 530. In addition, the brush body includes a handle 520.

Referring to Figure 1B, the "bristle tail surface" defined by the distal end of the bristles is shown in Figure 1B (which is indicated by broken lines and dotted lines). The term "bristle end surface" 550 does not require any material other than the bristles themselves. Instead, the term indicates that the surface can be created by interpolating the ends of the bristles.

One of the protrusion features of the bristle end surface is characterized by its irregular shape and irregularity. Another feature of the bristles of the bristle end surface 550 is that the edge or outer portion of the bristle end surface is much shorter than the inner portion of the bristle end surface.

Referring to Figure 1C, it can be clearly seen that the bristle region 540 includes two portions, an "inside" or "center" portion 560, wherein the bristles tend to be higher or even higher than the bristles at the edge or "outer" portion 570. .

Now in conjunction with the theory, it is believed that the hair itself can define a "hair surface" defined by the hair ends and/or the "highest" portion of the hair bundle on the skull surface. This "hair surface" (not shown) can also provide some degree of semi-random or randomness, or irregularity or disorder, especially when the hair is knotted. The present invention recognizes that due to the distal end surface 550 provides these irregular/semi-random/random properties (similar to the "hair surface"), which helps the bristles themselves penetrate into the hair surface in a manner that does not create strong tension or tension.

In some embodiments, penetration of the bristles into the hair enables the hairbrush 500 to properly comb the hair, rather than merely massaging the hair surface with a small amount or a small amount of bristles underlying the "hair surface." In addition, the "short" or "substantially shorter" bristles 570 of the outer region of the present invention also help to cause the distal bristle surface 550 to penetrate into the hair surface in a manner that effectively produces minimal or no pain. Combing.

For the purposes of the present disclosure, a "hairbrush" has a thickness/width of at least 0.5 mm.

In some embodiments, the inner region of the bristles 560 can provide one or more of the following features.

(i) "inside region" or "dense bristles" comprising at least 100 or at least 200 or at least 250 bristles having a width/thickness or diameter of at least 0.5 mm (eg, between 0.6 mm and 1.5 mm) (ii) the dense bristle tuft is disposed on a region of the bristle holding surface 530 of the hairbrush, having a size between about 20 and 100 square centimeters, for example between about 30 and about 50 square centimeters; (iii) the dense bristle system is disposed on the bristles holding surface 530 having a density ranging between about 4 bristles per square centimeter and 12 bristles per square centimeter, for example about 7 bristles per square centimeter; (iv) The dense bristles are arranged in a manner such that most or even most of the bristles are present (eg, at least 80% or at least 90%, Or at least 98% of the bristles are on a fixed grid - however, a small number of bristles (eg, at least 2% or 5% or 10% of the bristles) are located away from the location defined by the grid, In one mode, the inner region of the bristles includes about 300 bristles that define an "adjacent bristles" distance of about 1080 bristles, wherein the adjacent bristles are separated by less than 6.5 mm - 6 mm in this mode (remaining margin) Degree within a few percentage points, or even less than 2%), and at least 40% of these spacings are in fact at least 1 or 2 mm or at least 10% or 20% or 30% different from the first value Two values - for example 4.25 mm - however, other distances have different values; (v) the average height of the "inside region" bristles (ie, the inner region of the bristle bundle) is between 8.5 mm and 12 mm - for example between 10 and 11 mm; (vi) set a variety of different heights - for example, at least 5 or at least 8 or at least 12 or at least 15 or at least 20 different heights, the height and the inside The difference in height of the tufts of the region may be between 3.2 and 5 mm - for example, at least 25% Between at least 50% - for example between 33% and 45% of the average height of the bristles of the tufts; (vii) the height of the inner region of the tufts is between about 3.5 mm and about 16 mm; (viii) average The bristles are approximately 1 mm thick (eg, between about 0.85 and 1.15 mm) and range from about 0.5 mm (or 0.6 or 0.7 mm) and about 1.5 mm; (ix) are available in a variety of thicknesses and have standard The difference in thickness, the standard thickness difference of the bristle thickness is at least 7% of the average bristle thickness Or at least 10% or at least 12% or at least 15%; (x) on average, the higher bristles are thicker, while the shorter bristles are thinner (see Figure 11) - where the "x" axis is The height of the bristles in millimeters, and the "y" axis is the thickness of the bristles in millimeters - it is clear from Figure 11 that the higher bristles tend to have a thicker thickness - this is helpful for providing different combinations of bristles (xi) The bristles of the bristle bundles in the medial region 560 generally tend to be tougher - but not completely tough, as this may cause pain to the scalp (hence, it has some degree of flexibility), but most/substantially Tough; (xii) These bristles are made of plastic material.

"External region bristles" are also provided in certain embodiments, and have the following characteristics: (i) the bristles 570 of the outer region are also disposed generally around the inner region 560 of the bristles in a fixed density per unit area. Above, generally but not entirely, the bristles surrounding the inner region of the bristles holding surface 530 - in one example, the density is substantially one greater than the bristles of the inner region 560; (ii) The average height of the bristles of the "outer region" of the bristles is up to, for example, 50%, or up to 40%, or up to 30%, or up to 20%, or up to 15% of the average bristles of the inner region bristles; Iii) the number of bristles of the bristles in the outer region is at least 15% or 20% or 30% of the number of bristles of the inner bristles; (iv) in some embodiments, the bristles of the outer region bristles vary less (or less) ) - Therefore, its average thickness is about 1 mm, but the standard difference is the most It can be as much as 0.1 or at most 0.05 mm (or even less) - for example, up to 30% of the standard difference in bristle thickness of the inner region.

In certain embodiments, the bristles of the inner region 560 and/or the outer region 570 have substantially rounded ends - that is, at least substantially at least 60% or 75% or 85% or 90% of the majority. The bristles have rounded ends - this helps to provide a more comfortable effect when the bristles touch the scalp.

Figures 2A-2G provide additional supplemental descriptions of the hairbrush in certain embodiments.

Figures 3 through 4 show the bristle arrangement locations in certain embodiments. As is apparent from Figure 4, the bristles of the inner region are arranged to have a substantially fixed bristle density per unit area (but not a fully fixed bristle density).

Figure 5 shows a height histogram of the bristles of the medial region in certain embodiments - in this example a large number of height variations are provided, and Figure 6 shows the outer bristles disposed around the inner region of the bristles.

Figure 7A shows the position of the "very high" bristles of the medial region (i.e., the bristles whose height exceeds the average AVG and the sum of the standard differences) - these may include a total number of bristles of at least 5% or 10% or 15% of the medial region.

Contrary to the pattern of Figure 4, where the bristles (i.e., all of the bristles without height restrictions) are relatively evenly distributed in the area of the inner region of the bristle, it is seen in Figure 7A that very high bristles are irregularly (or randomly Distributed locally or semi-randomly) in the area of the bristles holding surface 530 of the bristles 560 that hold the inner region.

Therefore, in Figure 7A, it can be seen in the inner region of the bristles. These areas include very high bristles of "clumps" or "bundles" clustered together (in these areas, at least 3 or at least 5 or at least 7 bristle clusters/groups are bundled together, the density of which is Figure 4 At least 50% or 70% or 90% of the total bristle density of all of the bristles of the inner region 560 is observed. In addition, some regions in the position of the inner region 560 (eg, having a size of at least 5% or 10% of the total size of the "holding region" of the inner region 560) are relatively lacking "very high bristles" (Even if these areas are visible in Figure 4, there are other heights of bristles).

A similar pattern is shown in Figure 7D, where the "very short" bristles are present.

Since the height of the bristles of the inner region 560 varies in a random or semi-random manner (and generally independent of its position on the surface of the bristles), it can be seen that the bristles are limited to a certain height, "Very high" or "very short" bristles may be scattered in random or "semi-random" positions, which are scattered in "irregular positions" in an irregular or aperiodic manner.

This pattern is more commonly referred to as "outer layer outliers" (Figs. 7A, 7D) and is less commonly referred to as bristles having a height closer to the "central" value.

This pattern is only used for this "inside region" 560 - in some embodiments, there is little change in height in the outer region 570.

Figure 8 shows that the "height difference position" (i.e., the "average position" defined by a pair of bristles spaced less than 6.5 mm) is distributed in a substantially fixed manner.

However, when plotting the "height difference position" limited by the "very small" or "very large" height difference (Figs. 9A, 9D), the density is not complete. It is fully fixed and an irregular pattern is observed.

Figures 9B to 9C show the difference in height between small and large, respectively.

In some embodiments, the bristles of the inner region 560 and/or the outer region 570 are generally parallel to each other.

In some embodiments, the average bristle height at different locations in the inner region 560 (i.e., a circular control region that is at least 10% of the total area of the inner region 560) is generally Fixed - that is, a difference of approximately 1 cm is maintained at different locations in the medial region 560. This fixability can also be observed in the "height standard deviation".
