Haircutting collar, method of making and using

Abstract

A re-useable haircutting collar that is water resistant to dripping liquids and hair particles to protect a user's clothing and skin. The collar is made from flexible silicone or latex of a shore rating of extra soft to soft, skin adherent, non-toxic, and is a ring-shaped sheet, with an inner edge, mid-section, and outer edge, and with two opposing ends that overlap. The ends are tightly self-adhering to each other; therefore, the collars do not require fasteners to secure the ends together, and can be easily adjusted to fit any neck size to form a tight, but comfortable water seal. The collar is also lightweight and bendable to lay about vertically against the base of a user's neck and angled along their collarbone. Different collars embodiments also comprise differences in the thickness along the collar width at the top surface to provide different levels of collar flexibility.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

(16) With reference now to the drawings, FIGS. 1-12 depict three exemplary embodiments of a re-useable haircutting collar, generally referenced as 10 for the first embodiment, 20 for the second embodiment, and 30 for the third embodiment. The three exemplary embodiments disclosed herein have the same general annular or ring shape, with a center hole sized to fit a human neck, and with the primary difference being in the thickness of the collar top surface along the width (radius) from the collar inner edge to the collar outer edge (e.g. see FIGS. 11A-11C). It is noted, though, that one of skill in the art would readily know of other collar shapes comprising a neck-sized center hole (e.g. rectangular, oval, etc.) for use in the present invention.

(17) As illustrated in FIGS. 1-12, collars 10, 20, and 30 comprise a generally annular or ring-shaped sheet of a soft, flexible liquid-impervious material with an inner edge at the inner radius (see collar 10FIGS. 1-4, 14; collar 20FIGS. 5-7, 24; collar 30FIGS. 8-10, 34); and an outer edge at the outer radius (see collar 10FIGS. 1-4, 18; collar 20FIGS. 5-7, 28; and collar 30FIGS. 8-10, 38), and a mid-section between the two (e.g. FIG. 1, 16).

(18) Collar Size

(19) The 95.sup.th percentile adult American male has a neck radius of about 67 mm, as measured from the center of the neck (i.e. the neck center) to the outer skin of the neck (see NASA, Man-Systems Integration Standards, Vol. 1, Section 3). The average female child ages 6-10 has a neck radius of about 41 mm (see Katz, S L et al., BMC Pediatrics 2014, 14:159). A range in the collar sizes produced must be determined in order to accommodate these ranges in common neck sizes. Since the friction based fastening technique utilized by this invention requires the collars ends to overlap and bond to each other based on friction and self-adhering material properties, all collars must have a radius and circumference somewhat larger than the neck of their intended wearer (e.g. about four to eight inches).

(20) For all embodiments, the inner radius ranges from about 60 to 100 millimeters as measured from the center of the circle created by the collar (i.e. the collar center) as positioned in FIGS. 1-12 to the collar inner edge; and the outer radius ranges from about 120 to 220 millimeters as measured from the collar center to the collar outer edge. In the three exemplified embodiments of FIGS. 1-12, the inner radius is about 75 to 80 mm, and the outer radius is about 155-160 mm; and/or the collar width is about 75 to 95 millimeters, such as about 85 millimeters.

(21) The collars may also be shaped into unisex sizes comprising, for example: child, adult normal, and adult extra-large.

(22) The various embodiments of the annular shaped collar 10, 20, 30 have dimensions as disclosed in the Table 1 infra.

(23) TABLE-US-00001 TABLE 1 Collar Range of Range of Width Inner Radius (mm) Outer Radius (mm) 60 mm 60-100 mm 120-160 mm 65 mm 60-100 mm 125-165 mm 70 mm 60-100 mm 130-170 mm 75 mm 60-100 mm 135-175 mm 80 mm 60-100 mm 140-180 mm 85 mm 60-100 mm 145-185 mm 90 mm 60-100 mm 150-190 mm 95 mm 60-100 mm 155-195 mm 100 mm 60-100 mm 160-200 mm 105 mm 60-100 mm 165-205 mm 110 mm 60-100 mm 170-210 mm 115 mm 60-100 mm 175-215 mm 120 mm 60-100 mm 180-220 mm

(24) The collar further comprises a top surface (see FIGS. 1-3, 13; FIGS. 5-7, 23; and FIGS. 8-10, 33); and a bottom surface that is in contact with the user's neck and clothing (see FIGS. 1-4, 15; FIGS. 5-7, 25; and FIGS. 8-10, 35).

(25) Collar Thickness:

(26) The thickness of the collar may be constant along its width (i.e. radius), and/or increasing from the inner edge to the outer edge (i.e. constant slope of increasing thickness, or constantly increasing slope to midsection, then constant thickness to outer edge). The collar thickness lies within one half to six millimeters, such as about one to three millimeters.

(27) In the exemplified embodiment of FIGS. 1-4, 11A, and 12, the collar thickness increases on the top surface at a constant rate from the inner edge 14 to the mid-section 16, which in the exemplified embodiments of FIGS. 1-4 is at about 110 mm radius, or twenty millimeters width as measured from the inner edge 14. This may create a faint ridge line 16 on the top surface 13, but not on the bottom surface 15 (e.g. see FIG. 4). Then the collar thickness is constant from the mid-section ridge line 16 to the outer edge 18.

(28) FIG. 3 provides a cross-sectional view of the cut line 3-3 of FIG. 2. The left side of FIG. 3 illustrates the top surface of the left side of the collar as positioned in FIG. 2, and it demonstrates the tapering upward of the collar thickness on the collar top surface 13 from the inner edge 14 to the mid-section 16, and then maintaining a constant thickness from mid-section 16 to the outer edge 18.

(29) The collar thickness for FIGS. 1-4 is further illustrated in FIG. 11A, which is a cross-sectional view of the cut line 11A-11A of FIG. 2. FIG. 11A demonstrates an exemplary embodiment comprising collar 10 with a thickness of one millimeter at the inner edge 14 that increases at a constant rate to a thickness of three millimeters at the mid-section 16, and then maintains the same thickness of three millimeters to the outer edge 18.

(30) In another embodiment that is exemplified in FIGS. 5-7 and 11B, the collar thickness is constant from the inner edge 24 to the outer edge 28. FIG. 7 provides a cross-sectional view of the cut line 7-7 of FIG. 6. The left side of FIG. 7 illustrates the left side of the collar as positioned in FIG. 6, and demonstrates the constant collar thickness from the inner edge 24 to the outer edge 28.

(31) And the collar thickness for FIGS. 5-7 is further illustrated in FIG. 11B, which is a cross-sectional view of the cut line 11B-11B of FIG. 6. FIG. 11B demonstrates an exemplary embodiment comprising collar 20 with a constant thickness of one and a half millimeters from the inner edge 24 to the outer edge 28.

(32) In another embodiment that is exemplified in FIGS. 8-10 and 11C, the collar thickness increases at a constant rate from the collar inner edge 34 to the collar outer edge 38. FIG. 10 provides a cross-sectional view of the cut line 10-10 of FIG. 9. The left side of FIG. 10 illustrates the top surface of the left side of the collar as positioned in FIG. 9, and it demonstrates that the collar thickness increases at a constant rate from the inner edge 34 to the outer edge 38.

(33) And the collar thickness for FIGS. 8-10 is further illustrated in FIG. 11C, which is a cross-sectional view of the cut line 11C-11C of FIG. 9. FIG. 11C demonstrates an exemplary embodiment comprising collar 30 with a thickness of one and a half millimeters at the inner edge 34 that increases at a constant rate to a thickness of three millimeters at the outer edge 38.

(34) Collar Ends:

(35) the collar further comprises two opposing ends that overlap in a self-adhering manner due to the material properties of the collar. And while the ends self-adhere in a strong bond, they are easily pulled apart without damaging the collar or the user's skin. The collar ends may comprise a variety of shapes, such as the exemplified curved ends (e.g. see FIGS. 1-2, 4, ends 12; FIGS. 5-6, ends 22; FIGS. 8-9, ends 32). Or the collar ends may be rectangular-shaped, or a decorative shape, as long as the ends are long enough to be securely self-adhering.

(36) Because the collar ends strongly bond together, then the collars of the present disclosure do not require additional fasteners to secure the ends of the collar together, such as snaps, Velcro-like tabs, magnets, etc. that the prior art requires. And because the collar ends are not limited by the use of fasteners with neck size settings, then the collars of the present disclosure are able to fit any size human neck and at a tightness that is comfortable for the user while still being able to prevent any liquids or hair particles from slipping beneath the collar.

(37) And as exemplified in FIG. 12, when the collar is in position around the user's neck, the collar ends 12 may be positioned to overlap near or slightly in front of the user's shoulder after laying the middle of the collar on the user's chest-throat and wrapping the collar ends 12 around the back of the user's neck. The location of the collar ends overlapping can widely vary, and is dependent on: if the collar was mounted from the front or back or side, the circumference of the user's neck and collar, and how tight the collar is wrapped.

(38) Materials and Methods of Making

(39) The method of making the collar of the various embodiments disclosed herein comprises the use of a soft, flexible, fluid impervious, non-porous, self-adhering material, safe for use in contact with human skin, such as: cured silicone rubber because of its anti-microbial properties; latex rubber material; or platinum cured silicone rubber because of its known safety for skin and food use.

(40) It is well known by the skilled artisan that rubber materials are given a hardness rating that comprises a shore rating of: extra soft, soft, medium or hard, or the like. The material of the re-useable haircutting collar of the various embodiments disclosed herein comprise only an extra soft or soft shore hardness rating that is safe to use in contact with human skin. Examples of materials include one or more of: condensation cured silicone; platinum cured silicone; silicone that is non-toxic or irritating on contact with human skin; or latex rubber material; and, wherein the material comprises an extra soft to soft hardness rating of one of the following types: Shore 0A to 30A; Shore 0B to 17B; Shore 0C to 9C; Shore 0D to 6D; Shore 0O to 42O, and Shore 20 OO to 70 OO; or any combination thereof.

(41) In one embodiment, the collars are fabricated from thin sheets of platinum cured silicone of about Shore 2A. They may also be packaged for individual dispensing as needed.

(42) Individual collars may be produced by creating collar molds made from solid material such as aluminum, stainless steel, or acrylic. The acrylic mold is carved out using computer numerical control (CNC) milling to reproduce a cavity with the size and shape of the desired collar, such that the diameter and depth of the mold cavity (e.g. substantially ring or annular shaped) equals the width, length, and thickness of the collar.

(43) In an embodiment, liquid platinum and liquid silicone are co-mixed to produce a solid platinum cured silicone of Shore 30A or softer (e.g. about Shore 2A or the like). The liquids are pre-mixed and then poured or injected into the mold cavity, and the top surface is scraped to a be level. The silicone is then cured to a solid composition, removed from the mold, and trimmed.

(44) The top surface of the collar may also be embossed, debossed or otherwise labelled with a logo or trademark of the manufacturer or owner of the collar. The label may be incorporated into the mold. For example, the bottom surface of the mold is the top surface of the collar, and a logo or trademark is carved into the mold (embossed) or extends out from the mold (debossed).

(45) The collar may also be: colored or non-colored translucent; or colored or non-colored opaque. One of skill in the art would know of ways to color the rubber doing the collar manufacturing and curing process. In an embodiment disclosed herein, liquid pigment is added when mixing the platinum catalyst (e.g. pure platinum suspended in liquid carrier) and the silicone liquid.

Exemplification: Platinum Cured Silicone

Steps of ManufacturingSmall and Large Scale

(46) Creating a Mold: For individual-manual processes in small scale production of the collar, the user creates a mold from 0.25 to 0.5 thick cast acrylic sheets that are at least 2 wider and longer than the outer diameter of the collar. Using CNC carving or milling machine (e.g. Inventible X-Carve CNC Carving Machine 1000 mm1000 mm), the user mills out the pocket that will create the mold cavity for the collar. The user then hand polishes and cleans up imperfections in the mold once milling is completed.

(47) For creating a mold for large-scale production of the collar, a stainless-steel mold is created comprising two parts (e.g. top and bottom). Channels are also carved into the mold for the silicone to be injected and for air to escape.

(48) Mixing Platinum and Silicone:

(49) Steps for producing platinum cured silicone are well known in the art (e.g. U.S. Pat. No. 5,438,112, issued Aug. 1, 1995 to Wong and entitled Methods of Curing Silicone Resin, which is incorporated herein by reference in its entirety). In small and large-scale production, the user measures equal parts by weight or volume of liquid silicone base and a platinum catalyst hardener (e.g. Smooth-On Dragon Skin FX Pro 2A). The user also measures appropriate pigmenting material for the desired color mix and intensity (e.g. Smooth-On Silc Pig Silicone Pigmenting Set). Then the user combines the base, catalyst, and pigment into a container four times the required volume. The user stirs the mixture very thoroughly until it is completely mixed to an even color.

(50) Degassing Silicone:

(51) In small and large-scale production, the user places the container with the platinum silicone mixture in a vacuum degassing chamber, and de-gases the mixture at 29 inHg vacuum pressure for 30-45 seconds. This will cause most of the entrapped air to expand into large bubbles, which then pop and release the entrapped air. The user then releases the vacuum and removes the platinum silicone container.

(52) Pouring Versus Injecting Platinum Silicone Mixture:

(53) In small scale manufacturing, the user pours the platinum silicone mixture into the clean mold that was created in the first step, thus producing a thin consistent stream from a height of about twelve inches. The user pours in one fixed position and allows the platinum silicone mixture to flow throughout and across the mold; and continues to fill the mold until it is filled completely and a slight excess of the mixture is protruding from the mold surface. The user then moves a straight edge scraper across the top surface of the mold in order to remove the excess mixture, and so that the top surface of the mixture is parallel, aligned with the top surface of the mold.

(54) In large scale manufacturing, the degassed platinum silicone mixture is injected under high pressure such that it fills the cavity created between the two joined halves of the mold, and in automated processes.

(55) Mixture Curing to Solid Collar:

(56) In small scale manufacturing, the curing is done by allowing the mixture to set to a solid at room temperature, e.g. about forty minutes. In large scale manufacturing, high pressure is maintained and heat is applied to speed up the curing process, and by using methods well known in manufacturing rubber curing operations.

(57) Removing and Trimming the Solid Collar:

(58) In small scale manufacturing, the user carefully peels the solid collar away from the acrylic mold, inspects for defects and trims away any excess platinum cured silicone from the collar inner and outer edges. In large scale manufacturing, the mold is opened and the solid collar is ejected (e.g. automatedly). The collar is cleaned and excess (e.g. mold flashing) is trimmed using automated methods well known to one of skill in the art, such as liquid nitrogen tumbling process.

(59) Method of Use

(60) The various embodiments of the haircutting collar of the present disclosure can be used with or without a haircutting cape to protect a user's clothes and skin when the user's hair is washed, dyed, and/or cut; but use with a cape is recommended. When a haircutting cape is used as illustrated in FIG. 12, then the method of use of haircutting collar comprises the following steps that may be easily modified or re-ordered by the artisan to prevent liquids and/or hair particles from slipping into a user's clothing when the user's hair is being styled. In step one, the haircutting cape is draped over a user to cover both their clothing and exposed skin over their arms and hands and legs; and it is secured at the back of the user's neck. Preferably, the user is in a sitting position in a stylist's chair.

(61) In step two, the stylist grabs both collar ends 12, one in each hand, to pull and expand the collar into a fully opened, extended position. Because of the flexibility of the collar material, the stylist can significantly pull the collar ends apart and deform the shape of the collar from a ring to a substantially rectangular-linear shape.

(62) In step three, the collar is wrapped around the user's neck front-to-back, and comprises the stylist lowering the collar over the user's head and placing the center section (i.e. half way point between right and left side of collar) onto the user's throat near the larynx at the collar inner edge and extending onto the user's chest-collarbone at the collar outer edge. The stylist then wraps the ends of the collar over the user's shoulders, e.g. the left collar end over the right shoulder and the right collar end over the left shoulder. The top collar edge will automatically adhere or contour to the user's exposed neck upon contact, so the stylist should ensure that the collar is wrapped tightly enough for this to occur.

(63) Alternatively, in step three the collar wrapping is done back-to-front, and comprises the collar center section mounted against the back of the user's neck and then collar ends wrapped around to the front of the user's neck to create a tighter fit then wrapping from front-to-back. The stylist wraps the ends of the collar over the user's shoulders, e.g. the left collar end over the left shoulder and the right collar end over the right shoulder. This rear position mounting may provide a tighter seal than as described supra for a front position mounting. In either scenario, the collar ends will overlap about six to eight inches, although the skilled artisan would readily know how to adjust the collar length overlap.

(64) In step four, the stylist places one collar end 12, 22, or 32 against the back of the user's neck, and lays the opposing collar end on top of it. The two collar ends will then form a bond, and self-adhere to each other, and to the user's exposed neck skin, due to the material properties of the collar.

(65) The material properties of the collar's rubber prevent any type of liquid from soaking through the top and bottom surface of the collar and onto the user's skin and clothing.

(66) The tight fit of the collar around the user's neck may be adjusted to the user's comfort level and neck size by the stylist pulling the collar ends 12 gently apart without damaging them, and repositioning them as directed by the user, and then overlaying ends 12 again, wherein they will automatically self-adhere. The fit of the collar should be tight enough, while comfortable, to retard, diminish, or prevent any liquid and hair particles from slipping or dripping down the user's neck and under the cape.

(67) And in using collar 10, 20, 30, the collar width from the inner edge to the mid-section is substantially vertical against the user's neck and gently adhering or contouring to it, while the collar width from the mid-section to the collar outer edge is substantially angled at about: a 30 to a 90-degree angle; a 40 to an 80-degree angle, or a 45- e.g. a forty-five-degree angle; and so as to cover the user's shoulders and collar-bone. The collar is able to deform along the mid-section length because of the material properties of the collar rubber render it flexible in all directions.

(68) In step five, the collar is removed after the hair styling is complete, and by the stylist gently pulling the ends 12 of the collar apart. Due to the durability of the collar material, the collar ends 12 are not damaged when separated, nor do they lose their ability to self-adhere over repeated uses of the collar. The collar is then cleaned with soap and water to remove hair particles, and then sanitized by soaking in a bucket or sink or spraying on a cleaning solution that is approved for use in salons to sterilize haircutting utensils after each customer. Types of sanitizing solutions are well known to the skilled artisan, and comprise by way of non-limiting examples: Barbicide, alcohol based solutions, etc. The collar is then aired dried, or dried via the use of a blow dryer, and is ready for re-application to another user's neck/shoulders.

(69) Table 2, supra, provides alternative methods of sanitizing the collars. It is noted, though, that each state and local region is subject to laws and regulations pertaining to the operation of salons and barber shops that dictate methods of cleaning haircutting utensils, which are applicable to the res-useable collars disclosed herein.

(70) TABLE-US-00002 TABLE 2 Methods of Sanitizing Collars Method A - Barbicide Liquid 1. Immerse in Barbicide for 10 minutes. 2. Pat dry with clean towel. 3. Allow to naturally air dry or dry thoroughly with a hairdryer. Method B - Barbicide Wipes 1. Wet all surfaces of collar with a newly opened Barbicide wipe. 2. Keep surface wet with Barbicide for 2 minutes (may require additional wetting). 3. Pat dry with clean towel. 4. Allow to naturally air dry or dry thoroughly with a hairdryer. Method C - Autoclave 1. Place at least one collar in autoclave in single layer. 2. Maintain 121 C. and 15 psi for at least 30 minutes. 3. Allow to cool to room temperature before using the collar in contact with human skin. Method D - Machine Wash 1. Place at least one collar in a mesh containment bag. 2. Place in washing machine on high heat with disinfecting detergent (e.g. bleach). 3. Remove collars and allow to air dry or dry with a hair dryer (do not dry in machine dryer as they will pick up lint as they dry).
