Abstract:
An apparatus and system for preparing a hair coloring includes as graduated syringe and a container filled with a pigmented hair dye. The container includes an air-tight chamber and an opening, and also includes an engagement mechanism for installing the container on a rack for support. An air-tight reclosing seal at the opening allows the syringe to engage the air-tight reclosing seal, and extract the hair dye from the air-tight chamber. When the syringe is disengaged from the container, the air-tight reclosing seal closes off the air-tight chamber and permitting a known quantity of the hair dye to be withdrawn from the container into the syringe, allowing an accurate and repeatable quantity of hair dye to be dispensed from the container.

     BACKGROUND 
       [0002]    Hair coloring systems currently available on the market typically comprise a series of capped dye tubes, such as collapsible aluminum tubes, each containing a different color high-viscosity paste, or a bottle-type container holding a liquid. During the hair coloring process, a stylist dispenses the desired amount of a particular base pigment into a mixing receptacle. Additional pigments must be dispensed and mixed with the base to achieve a desired color. A developer or fixing agent will be added as well. Once the pigments and developer dispensed and blended, the mixture may be applied to a client&#39;s hair. 
         [0003]    These hair coloring systems have several drawbacks. When adding color from a tube, a user is prompted to “squeeze to a line,” wherein it is impossible to identify small amounts, such as milliliters. Because hair dye is obtained by hand from tubes or bottles, it is impossible to know the quantity of a particular pigment dispensed. Dyes must be measured accurately since a change of even 0.1 ml can alter the hue of a color mixture from one batch to the next. Independent studies have found that the best efforts using tube markings were only accurate to +/−50% of the total volume. The accuracy of color dispensed with a syringe fitted at its open end with a nozzle or tubing is to within +/−1% of the total volume. Accurate measuring equipment, which is common in a laboratory setting, is rarely found in conventional salons. For this reason, precise reformulation/duplication of a color can be difficult if not impossible. 
         [0004]    The bottles and tubes from which colors are dispensed are also not easily organized in a salon setting. Due to the speed at which hair professionals work and the numerous clients on which they work over the course of a given day, containers usually end up haphazardly thrown in drawers or on shelves, forcing stylists to search for a desired color among many disorganized dyes. 
         [0005]    Furthermore, because of the nature of aluminum tubes, i.e., capped cylinders similar to toothpaste tubes, it is difficult to dispense all of the dye from a single tube, resulting in wasted product. Approximately 25% of the product in a typical dye tube may be wasted due to a user&#39;s inability to completely dispense the product, or through drying and discoloration caused by oxidation of the dye from leaving off the cap. Tube-based dyes are also high in viscosity which makes them difficult to manage. 
         [0006]    Some attempts have been made to solve these problems. U.S. Pat. No. 7,407,055 to Rodriquez discloses a hair roots coloring kit, including a squeeze tube of hair dye and measuring devices such as syringes, a measuring cup and a pipette for establishing a dye quantity. In particular, a syringe may be inserted into a squeeze tube to retrieve hair dye. This invention contemplates conventional aluminum or similar hair dye squeeze tubes, and a dye comprising a viscous, high viscosity paste. For this reason, the dye must be pushed into a syringe by compressing the dye tube, rather than extracting dye with the syringe plunger. Furthermore there is no sealing arrangement between the tube and syringe, so that users must maintain them together under manual pressure to avoid leakage. Additionally, since there is no oxygen barrier between the syringe and the distribution end of the dye tube when uncapped, oxidation will occur. 
         [0007]    U.S. Pat. No. 7,961,303 to Saranow, et al. discloses a hair dye apparatus and method having a computer screen for selecting a color from a color palette, and a dye quantity. The apparatus indicates the dyes a user will mix, and the user dispenses the dyes in a bowl atop a small electronic scale. While this apparatus keeps individual color containers separate and organized, it is bulky, complicated to use, and lacks the accuracy needed for professional applications. Also, it fails to solve the problem of wasted product. 
         [0008]    U.S. Pat. Publication No. 2012/0048880 to Damolaris also discloses a dispensing apparatus for hair dye. In Damolaris, a user enters information relating to a desired color using a computer terminal, and the apparatus dispenses a predetermined amount of developer. While this apparatus presumably dispenses all of the dye in a container, it requires an expensive computer processor and substantial user training to operate. This invention fails to teach measurement or dispensing color. Rather, it&#39;s sole function is to measure developer. 
         [0009]    For these reasons, commercial hair dye systems as known in the art are both wasteful and prone to error. Consequently, there is a need for a hair coloring system for commercial salons and professional stylists that allows users to accurately measure the pigments they use, and which also allows users to extract virtually all of a dye product from its packaging. Further, there is a need for a system that remains organized, allowing stylists to quickly and easily find colors to mix. 
       SUMMARY 
       [0010]    An apparatus tor preparing an accurate and repeatable hair coloring includes a graduated measuring and dispensing vessel, together with a flexible container, preferably in the form of a laminated flexible packaging pouch, having a hair dye contained in an air-tight configuration in the container. The container includes an air-tight chamber, an opening, a self-sealing valve for receiving the graduated measuring and dispensing vessel in a substantially air-tight fashion, a closure for protecting contents within the container from being unintentionally discharged therefrom, and further includes a means for engaging the container with a container holder to support it. This may take the form of a rack in which the container sits, may include pegs from which the container hangs or provide a similar arrangement in which the container is suspended for easy access by a hair color professional. 
         [0011]    The container of the present invention is preferably in the form of a flexible packaging pouch which, in addition to its being air-tight, is constructed in such a way that the product contained in the container does not chemically react in any way with the air-tight inner chamber of the container. Typically, the flexible packaging pouch will be constructed of multiple layers of material, i.e. a laminate material. An example of a suitable laminate material includes one having an inner layer, an outer layer and an intermediate layer. The intermediate layer may be metallic in nature such as, for example, aluminum foil. The inner layer that is in direct contact with the product may be made of polyethylene, although any flexible material that is inert to the product may be employed. The outer layer may be made of any material that lends itself to printing thereon, and provides protection to the intermediate layer from physical abuse. One example of a laminate flexible packaging pouch that may be used in accordance with the present invention is found in US 20120205267, the entire content of which is hereby incorporated by reference. It should be noted, however, that the flexible packaging pouch may be constructed of any single material, or layers of material that render it sturdy, airtight and inert to the product contained therein. 
         [0012]    The apparatus of the present invention also includes a self-sealing valve provided with a closure cap located at the opening/spout of the pouch, such that when the measuring and dispensing vessel engages the self-sealing valve, the hair dye may be extracted from the air-tight chamber, and when the measuring and dispensing vessel is disengaged from the container, the self-sealing valve closes of the air-tight chamber. In this manner, a user may withdraw a known quantity of the hair dye from the container into the measuring and dispensing vessel, combine it with known quantities of other color hair dyes, thereby allowing an accurate quantity of total hair dye to be dispensed from the container enabling the hair professional to mix an accurate and repeatable hair dye color. 
         [0013]    The self-sealing valve is preferably made from an inert substrate. Examples thereof include rubber and rubber-like materials such as, for example, silicone. The valve provides a self-sealing dispensing orifice through which the contents of the container may be dispensed, while providing a resilient sealing means when dispensing is not desired. The self-sealing valve preferably also comes with a cap member to further protect the contents inside the container. 
         [0014]    According to an embodiment of the present invention, there is also provided a quick-acting coupling mechanism comprised of two parts, a plug representing the male half of the coupling mechanism and a socket representing the female half. In this embodiment, either the valve or the vessel can serve as the male or female half. In a particularly preferred embodiment, the self-sealing valve with closure cap is configured in such a way that it serves as the female socket half of the coupling mechanism and the vessel is configured in such a way that it serves as the male plug half. When coupled properly, the valve and vessel are both sealed and locked together. Examples of suitable coupling mechanisms include, but are not limited to bayonet couplings that rely on a twist locking arrangement, or those coupling mechanisms where the plug (vessel) has a lip/flange on the end being inserted into the valve which is sufficiently larger in diameter than the opening of the socket (valve) into which the plug is being inserted such that when the vessel is pushed into the valve, a seal is formed and the two components are removably locked in place. The precise type of coupling mechanism employed is not critical, so long as the valve and vessel are sealed and locked together when coupled. 
         [0015]    The self-sealing valve, together with the quick-acting coupling mechanism, serves two important functions. First, they enable the vessel to be quickly and easily coupled and de-coupled from the container in a secure manner. Secondly, they further inhibit the introduction of ambient air into the container associated with the extraction step to further limit undesirable degradation of the product due to oxidation. 
         [0016]    In one embodiment, the container includes an engaging device at the opening for releasably connecting the measuring and dispensing vessel to the container in an air-tight manner to prevent the measuring and dispensing vessel from inadvertently disengaging from the container. Additionally, the container may include an outer layer made of a semi-rigid poly-plastic material, such that in one embodiment the container is essentially a collapsible bag while in another, it retains a uniform outer shape while an interior collapsible bag deforms. Preferably, the opening is at the bottom of the container relative to a container label. 
         [0017]    In addition to an engaging device for retaining the container and the measuring and dispensing vessel in a locking configuration, in an alternative embodiment, to prevent hair dye from exiting the container when the measuring and dispensing vessel disengages the container, an air-tight reclosing seal, for instance a self-sealing orifice reducer may be used instead of or along with the engaging device for added security. 
         [0018]    The container holder of the apparatus may take the form of a rack capable of holding multiple containers including a complete color line from a hair dye manufacturer. The multiple containers may hang suspended from the rack. In this manner the rack may hold multiple containers of the same color in a row, such that a full container can be brought forward when an empty container is removed from the rack. The rack may also be a holder in which multiple containers are seated. In this arrangement access to the bottom of the containers is provided by slots or holes in the rack. 
         [0019]    Preferably the measuring and dispensing vessel comprises a graduated reusable device capable of accurately dispensing a known quantity of hair dye. In a preferred embodiment a syringe or syringe-type vessel is used. The vessel is configured such that its extraction/dispensing end is capable of both effectively penetrating through the self-scaling dispensing orifice of the valve into the air-tight chamber of the container, as well as easily withdrawing product from inside the container. The extraction/dispensing end should be of an appropriate diameter to facilitate the efficient extraction of products of varying viscosities. The extraction/dispensing end may be in the form of a tip that may be integrally connected to the vessel. The tip, however, may also be removably/interchangeably connected to the vessel and may come in various configurations and diameters. 
         [0020]    To assist in securely connecting the syringe with the opening of a container, the opening and the syringe may be equipped with a luer-lock arrangement and the opening include a shut-off valve similar to an IV bag. In another embodiment an orifice reducer alone may be used. 
         [0021]    Regardless of the locking arrangement of the syringe and opening, the syringe preferably includes an oxygen-free barrier to prevent oxidation or similar degradation of the hair dye and its color. One contemplated method of presenting an oxygen free barrier that resists the corrosive qualities of ammonia-based hair dye is a fluorination barrier treatment with which the surfaces of a syringe or similar vessel may be treated. 
         [0022]    Once the syringe has extracted a desired quantity of hair color from one container, a user may engage the syringe with a second container bearing a second color. Once each quantity of hair dye is extracted from a container, the dyes may be mixed to obtain a predetermined color in a mixing bowl. Preferably the mixing bowl is made from a material that will not affect or take on the hues of the hair dye. 
         [0023]    In the event the same syringe is used to extract different colors from different containers, the syringe will need to be washed in between extractions. This additional washing step can be avoided, however, by assigning a single syringe to each specific color. The syringe, when not in use, can remain coupled to the self-sealing valve of the container. Thus, by assigning a specific syringe to a specific color, an intermediate washing step can be avoided, thus further enhancing the efficiency of the system. 
         [0024]    In an alternative embodiment, an apparatus for preparing hair dyes includes a graduated measuring and dispensing vessel, such as a syringe as described above, which is filled, i.e., pre-filled, with a predetermined amount of hair dye. Preferably a re-sealable cap is provided for covering an opening of the graduated measuring and dispensing vessel in an air-tight configuration to prevent oxidation and leakage of the hair dye prior to and after use. 
         [0025]    A rack for storing multiple graduated measuring and dispensing vessels in an organized arrangement according to color is preferably provided in this embodiment, and allows them to be stored in rows of the same color to prevent running out of a particular hair dye. In this embodiment, the graduated measuring and dispensing vessel also includes an oxygen-free barrier. 
         [0026]    Since the oxygen free barrier is opaque, a label may be included on the exterior of the graduated measuring and dispensing vessel corresponding to hair dye&#39;s color. Like prior embodiments, the surfaces of the measuring and dispensing vessel may be treated with a fluorination barrier treatment or similar preservative for oxygen-free storage. Furthermore, since the graduated measuring and dispensing vessel in this embodiment is essentially the container for a hair dye, it may include a handle for engaging the rack. 
         [0027]    In order to use the hair coloring apparatus to mix an accurate color, a first container is provided having a quantity of hair dye contained in it. A first opening is provided in the first container, the opening presenting an air-tight re-closable seal on the first container. A graduated measuring and dispensing vessel, such as a syringe, capable of holding a predetermined quantity of hair dye is then provided, and is used to access the first opening with the graduated measuring and dispensing vessel, withdrawing a first predetermined quantity of hair dye from the first container and dispensing it in a mixing bowl. 
         [0028]    A second container is then provided having a quantity of hair dye contained therein. Like the first container, the second container has a second opening with an air-tight re-closable seal on the second container. The second container is accessed with the graduated measuring and dispensing vessel and a second predetermined quantity of hair dye withdrawn from the second container. The second predetermined quantity of hair dye is then dispensed into the mixing bowl and mixed with the first predetermined quantity of hair dye. A developer, preferably peroxide based, may then be added to the dye, followed by application onto a consumer&#39;s hair. 
         [0029]    Preferably, an oxygen barrier may be provided on the graduated measuring and dispensing vessel (e.g. syringe) to prevent degradation of the hair dye, particularly in an embodiment where the container takes the form of a syringe, obviating the need for connecting a syringe to a separate container of hair dye. Additionally a rack may be provided for the first container and the second container, or in an alternate embodiment hair dye-containing syringes to keep the colors organized. In a preferred embodiment, additional containers having quantities of different hair dye colors may be loaded in and dispensed from the rack. 
         [0030]    The apparatus of the present invention can also be adapted for use by retail consumers who prefer to color their own hair rather than having it done professionally. According to this embodiment, the system comprises at least two flexible packaging pouch containers, one with a hair dye product and one with developer. Each pouch has a self-sealing valve with cap closure located at a dispensing end of the pouch, at least one extraction/dispensing graduated vessel, a quick-release locking mechanism having a female socket portion at the valve opening and a male plug portion at the vessel opening, at least one mixing bowl, instructions as to specific quantities of dye and/or developer to be mixed together and, optionally, a root touch-up tool capable of directing hair dye directly onto a consumer&#39;s hair roots. 
         [0031]    In operation, a consumer wanting to apply a specific color onto their hair would withdraw a specific amount of hair dye from one pouch using the vessel, dispense the dye into the mixing bowl, add developer from a second pouch thus forming a ready-to-apply hair color, and apply it onto their hair. 
         [0032]    In the event a consumer desires a custom, in-home hair color treatment for their hair, such as they might obtain at a professional hair salon, multiple flexible packaging pouch containers, each containing a different color hair dye, can be provided. Instructions for mixing predetermined amounts of each hair dye product are provided, whereby the consumer will extract the predetermined amount of each hair dye color from their respective containers, mix the colors together in a mixing bowl, add a predetermined amount of developer, and apply the mixture onto their hair. 
         [0033]    It should be noted that the apparatus of the present invention may also be used to dispense and/or mix any ingredients that are susceptible to degradation when exposed to ambient air and/or UV light. Thus, according to yet another embodiment of the present invention, there is provided a system for applying a skin treatment composition onto a consumer&#39;s skin. In this embodiment, the product contained in the containers is a formulation that is sensitive to degradation, such as oxidation, when exposed to ambient air. For example, formulations containing potent antioxidants such as vitamin C, resveratrol, retinol, ferulic acid, and the like can be extracted from their respective flexible pouches and mixed together, in situ, in a mixing bowl, just prior to application onto the skin. Because the formulations are protected from unwanted oxidation in the pouches both pre- and post-extraction therefrom, the likelihood of their degrading prior to complete exhaustion of the product from the pouch is greatly diminished. Therefore, a consumer at home and/or professional working, in a dermatologist office and/or spa can have a measure of confidence that the formulations contained in the flexible pouches will retain a level of efficacy after numerous uses. 
         [0034]    In one alternative embodiment, the present invention may be characterized as a kit having a graduated measuring and dispensing vessel, at least one flexible packaging pouch container having a hair dye product contained therein, the container comprising an air-tight chamber and an opening, at least one flexible packaging pouch container having a developer contained therein, the container comprising an air-tight chamber and an opening. A self-sealing valve is provided with a closure cap and dispensing orifice located at the opening of the pouch and capable of receiving the measuring and dispensing vessel, such that when the measuring and dispensing vessel engages with the self-sealing valve, the hair dye products may be extracted from the air-tight chamber via the dispensing orifice, and when the measuring and dispensing vessel is disengaged from the self-sealing valve, the dispensing orifice closes, thereby sealing the air-tight chamber. 
         [0035]    A quick-acting coupling mechanism is configured such that the self-sealing valve serves as the female socket end, and the graduated measuring and dispensing vessel serves as the male plug end. At least one mixing bowl is included into which the hair dye product and developer are dispensed and at least one mixing tool is included, for mixing the hair dye product and developer in the mixing bowl, thereby permitting a known quantity of the hair dye product and/or developer to be withdrawn from their respective containers into the measuring and dispensing vessel, allowing an accurate and repeatable quantity of hair dye and/or developer to be dispensed from their respective containers. Preferably, the kit may have at least one additional flexible packaging pouch container having a different color hair dye product contained therein, such that the two hair dye products, when mixed together and with the developer, form a custom hair color product. 
         [0036]    In another embodiment, the invention is an apparatus for preparing an anti-aging treatment composition. In such an embodiment, the apparatus includes a graduated measuring and dispensing vessel, flexible packaging pouch container made from an inert substrate that is impervious to UV light and/or ambient air, having at least one anti-aging active compound sensitive to ambient air and/or UV light contained therein, the container comprising an air-tight chamber and an opening, self-sealing valve provide with a closure cap and dispensing orifice, located at the opening of the container and capable of receiving the measuring and dispensing vessel, such that when the measuring and dispensing vessel engages with the self-sealing valve, the anti-aging active compound may be extracted from the air-tight chamber via the dispensing orifice, and when the measuring and dispensing vessel is disengaged from the self-sealing valve, the dispensing orifice closes, thereby sealing the air-tight chamber, and a quick-acting coupling mechanism configured such that the self-sealing valve serves as the female socket end, and the graduated measuring and dispensing vessel serves as the male plug end. 
         [0037]    This embodiment permits a known quantity of the compound to be withdrawn from the container into the measuring and dispensing vessel, allowing an accurate and repeatable quantity of anti-aging compound to be dispensed from the container. The graduated measuring and dispensing vessel is preferably shaped as a syringe provided with an extraction/dispensing end with an opening having a predetermined diameter that is capable of both effectively penetrating through the self-sealing dispensing orifice of the self-sealing valve into the air-tight chamber of the container, and efficiently withdrawing product from inside the container. The extraction/dispensing end may be shaped like a tip and integrally connected to the vessel. 
         [0038]    In one alternative of the embodiment, the tip may be removably/interchangeably connected to the vessel and comes in various configurations and diameters. The flexible packaging pouch container may be made from a laminate material, the self-sealing valve with closure cap may be made from an inert substrate, and the inert substrate may be chosen from rubber or a rubber-like substance such as silicone. Additionally, the quick-acting coupling mechanism may be chosen from a bayonet coupling, that relies on a twist locking arrangement, or a force actuated coupling mechanism comprised of a lip/flange on the plug end of the vessel that is inserted into the female socket end of the valve, such that when the vessel is pushed into the valve, a seal is formed and the vessel and valve are removably locked in place. The anti-aging compound may be an antioxidant, and chosen from vitamin C, resveratrol, retinol, ferulic acid and mixtures thereof. 
         [0039]    In an alternative anti-aging embodiment, the invention may be characterized as a kit having a graduated measuring and dispensing vessel, at least one flexible packaging pouch container made from an inert substrate that is impervious to UV light and ambient air having at least one anti-aging active compound sensitive to ambient air and/or UV light contained therein, the container comprising an air-tight chamber and an opening, a self-sealing valve provided with a closure cap and dispensing orifice, located at the opening of the pouch and capable of receiving the measuring and dispensing vessel, such that when the measuring and dispensing vessel engages with the self-sealing valve, the anti-aging compound may be extracted from the air-tight chamber via the dispensing orifice, and when the measuring and dispensing vessel is disengaged from the self-sealing valve, the dispensing orifice closes, thereby sealing the air-tight chamber. 
         [0040]    A quick-acting coupling mechanism is configured such that the self-sealing valve serves as the female socket end, and the graduated measuring and dispensing vessel serves as the male plug end, and optionally, at least one bowl into which the anti-aging compound may be dispensed to permit a known quantity of the anti-aging compound to be withdrawn from the container into the measuring and dispensing vessel, allowing an accurate and repeatable quantity of anti-aging compound to be dispensed from the container. The kit preferably includes at least one additional flexible packaging pouch container having a different anti-aging active compound contained therein, such that the two anti-aging compounds, when mixed together, form a custom anti-aging treatment product.

     DESCRIPTION 
       [0061]    Referring to  FIG. 1 , the system comprises a series of individual dye containers  10 . Like the aluminum hair dye tubes currently known in the art, each container preferably holds a different pigment, including base colors, highlighting tones, and developer (also known as “fixing solution”). Unlike tubes known in the art, the containers  10  are collapsible, and may comprise single-layer flex-packaging (e.g. IV bag type pouch (see  FIG. 10 )), or the containers  10  may be multi-layered, comprising a flexible and collapsible air-tight inner layer  17  containing a liquid dye, and an outer layer  19  made of a semi-rigid poly-plastic material (see  FIG. 4 ). 
         [0062]    In one embodiment the laminated material forming as flexible container for holding hair dye or similar materials is contemplated. The laminated material may include a first, internal surface, and a second, external surface. Optionally, an intermediate foil barrier layer (not shown) may be included, separating the first and second surfaces. 
         [0063]    The containers  10  are adapted to dispense their contents from the bottom relative to their labels  11 , and are designed to removably install into a rack  12 , which is adapted to hold multiple containers  10 . Preferably, the rack  12  comprises a polymer-type horizontal and expandable storage adapted to hold numerous containers  10 . 
         [0064]    Referring to  FIG. 2 , A graduated piston syringe  14 , having a calibrated scale  15  on the barrel for reading volume, and preferably clear to see the color of its contents, is used in connection with the containers  10 . The syringe  14  preferably comprises a first locking adapter  16  such as a luer-lock at the tip, and is sized appropriately for normal volumes of hair dye. The first locking adapter  16  is designed to lockably engage a neck  18  (see  FIG. 4 ) on a container  10 . In the illustrated embodiment, the male portion of a luer-lock is shown at the tip of the syringe  14 . 
         [0065]    Referring to  FIG. 3 , each container  10  neck  18  is equipped with to second locking adapter  20 , complimentary to the first locking adapter  16 , for example, the complimentary component of a luer-lock. Preferably, the neck  18  of each container  10  will also incorporate an air-tight seal  22 , such as a ring-stopper (see  FIG. 14 ) to prevent leakage and oxidation of a container&#39;s  10  contents when the syringe  14  is removed. In this manner a syringe  14  can make a leak-proof connection to any container  10 . 
         [0066]    Referring to  FIG. 4 , in order to use the system, a user selects as color from among the containers  10  disposed in the rack  12 . With the desired color selected, the piston syringe  14  is brought to the neck  18  of a container such that the first locking adapter  16  engages the second locking adapter  20 , and the air-tight seal  22  is broken, allowing dye to enter the syringe  14  under negative pressure as shown in  FIG. 5 . Preferably, when the first locking adapter  16  and second locking adapter  20  are connected, they form an air-tight seal. Users may locate and dispense a known quantity of a known dye quickly when preparing a hair coloring mixture due to the organization of the containers in the rack  12  (not shown). 
         [0067]    Referring to  FIG. 6 , after a desired quantity of a given dye has been transferred to a syringe  14 , the syringe may be disengaged with the container  10 . In the case of a luer-lock adapter  16 ,  20 , the user would simply turn the syringe  14  relative to the container  10  while the container  10  is held in the rack  12  and prevented from turning by a pressure fit or obstruction fit between the rack  12  and the neck  18  of the container  10 . Importantly, once the syringe  14  disengages the second locking adapter  20  and seal  22 , the seal  22  closes, recreating an air-tight seal, and preventing the contents of the container  10  from leaking. In this manner, no dye is wasted during dispensing. Also, a low viscosity dye may be easily used without spillage. 
         [0068]    Referring to  FIG. 7 , once a user obtains a syringe  14  with the desired quantity of dye, the dye may be dispensed into a mixing receptacle  24  where it will be combined with other pigments, and developer as desired to achieve a specific, easily and accurately duplicated hair color. After the syringe  14  dispenses the dyes, it may be easily cleaned under running water before being re-used with other dyes or developers for other salon customers. 
         [0069]    Referring to  FIGS. 8-10 , embodiments of the invention comprising the aforementioned “IV Bag” type of container  10  are shown.  FIG. 8  shows a series of color containers  10  assembled in a rack designed to suspend individual containers in an organized and easy to access manner. The system may comprise horizontal and expandable storage racks  12  that holed the containers  10  such that an entire professional hair color product line and developer is contained in a rack  12 . The containers  10  securely hung from the storage racks  12  may be mounted on a wall in a salon in a highly organized and accessible manner. In  FIG. 9 , the containers are shown on an alternative carousel type rack. In this view re-sealable locking connectors  23  at the base of a bag-type color container  10  is shown connected to a syringe  14 . The container may also include a shut-off valve  24  for stopping the flow of hair dye once the syringe is removed.  FIG. 10  shows a variety of bag-type dye container with an adjacent syringe prepared for extracting dye from the container. 
         [0070]    Referring to  FIG. 11 , in an alternative embodiment, a single barrel syringe  14  may be manufactured with a predetermined quantity of dye pre-installed in the syringe  14 . Each syringe in this embodiment may have a unique color or shade inside, while a multi-layered oxygen-free barrier  24  lines the inside of the syringe barrel  26 . Due to the opacity of the oxygen-free barrier  24 , the color of the dye contained in the syringe  14  may be applied or labeled on the barrel  26  exterior, in order to ensure accurate dispensing, the syringe graduations  28  are preferably located on the plunger  30  designed to align with a marker  32 . In one embodiment, a screw-cap (not shown) may be installed at the end of the barrier, to provide a measurement guide. A handle  34  may be installed on the plunger  30  for incorporating multiple single syringes  14  into a rack system (not shown) bearing a variety of colors. 
         [0071]    In this manner, syringes  14  with commonly used colors may be purchased separately from other, less used colors. A plurality of these syringes  14  may be used to store the entire color line of a manufacturer. In one embodiment a single pre-loaded syringe may be a common 150 ml syringe, in other embodiments larger or smaller syringes may be employed as desired, including using a larger, 250 ml or greater syringe for commonly used colors to avoid syringe replacement. 
         [0072]    Referring to  FIG. 12 , the single pre-loaded syringes  14  may be stored in vertical rows on a horizontal rack  36  and removed by a stylist to dispense a desired quantity of pigment into a mixing bowl. Other syringes  14  of the same color may be stored behind the syringe-in-use. In an embodiment where individual syringes are removed and re-installed on a rack, each syringe plunger and/or barrel may also include indicia  38  matching indicia on the rack to ensure proper replacement of a syringe  14  after use. A cap  40  is preferably provided for each individual syringe  14  to prevent contamination by other colors. 
         [0073]    Referring to  FIG. 13 , an alternative embodiment may include a syringe  14  securely suspended from a rack  12 . In this embodiment, a front syringe in use is shown however other syringes of the same color may be stored on the rack behind the secured front syringe for replacing it when empty. In this embodiment, a stylist may hold a mixing bowl (not shown) under the securely mounted syringe  14  and depresses the plunger  30  to dispense color into the bowl. It is anticipated the viscosity typical of hair dyes is such that without pressure on the plunger  30 , even when inverted with the hub of the syringe  14  pointing downward, dye will not leak from the syringe  14 . Notwithstanding this property of the dye, a cap (not shown) may be proved for the tip of each syringe  14  to prevent cross-contamination and oxidation from occurring. 
         [0074]    In this manner a complete hair color line may be pre-packaged into a plurality of single-barreled, disposable plastic dose syringes  14 . The syringes  14  are preferably manufactured and packaged with predetermined quantities of hair color pre-loaded into the syringe  14 . Each syringe  14  has a unique color or shade inside each barrel  26 . A handle  34  or similar structure such as a hanger hole may be located at the to of the plunger  30  for holding multiple syringes in a vertical rack system storing, a variety of colors in a color line. To ensure accurate dispensing, the syringes  14  may be milliliter graduations located on the plunger  30  designed to alight with a marker  32  (such as an MDR ring) at the barrel  26  to provide a measurement guide and plunger  26  actuator. 
         [0075]    The system is entirely oxygen-free so that the colorant and developer is protected from being contaminated by oxygen, as oftentimes occurs with the conventional formulation methodology. To prevent oxidation and/or corrosion from occurring from highly corrosive ammonia-based hair dye, a multi-layered barrier may line the inside and in some embodiments including the exterior of the plastic syringe barrel  26 . An alternative feature to prevent oxidation and corrosion may include a fluorination barrier treatment, whereby fluorine atoms bonded to inner and outer surfaces of the syringe create a double-sided barrier. 
         [0076]    Due to the opacity of the oxygen-free barrier, the color of the dye contained in the syringe  14  may be applied or labeled on the barrel  26  exterior. A screw-cap may also be incorporated into the end of the barrier to prevent dripping and also serve as an oxygen barrier. 
         [0077]    As discussed, a plurality of the syringes may be used to store the entire color line of a manufacturer in a horizontal storage rack, and syringes containing commonly used colors may be purchased separately from other, with less used colors purchased more infrequently. A single pre-loaded syringe may be a common 150 ml syringe, in other embodiments larger or smaller syringes may be employed as desired, including using a larger, 250 ml or greater syringe for commonly used colors to avoid syringe replacement. 
         [0078]    In the embodiment with separate containers  10 , a manually operated, a clear, metrically calibrated reusable, needle-less 60 mL luer-lock syringe may be used. An assembly of multiple, multi-layer flex-packing containers  10  are each filled with a unique shade of hair color and developer. The color is withdrawn by the syringe to the exact millimeter from various containers  10  according to a predetermined formula and dispensed into a mixing bowl for combination. 
         [0079]    Two unique container designs are contemplated, one for color and one for developer. A first container may contain 6 ft ounces (i.e., 180 mL) of color. Incorporated into a spout at the bottom of the container  10  may be an airtight seal consisting of a permanently installed female to male in-line luer-lock connector with a shut off valve to prevent dripping and leakage. An oxygen barrier and highly secure connection between the pouch and syringe allows the system to be entirely oxygen-free so that the color and developer is protected from being contaminated by oxygen, as oftentimes occurs with the conventional formulation methodology. 
         [0080]    A second container design includes a self-sealing orifice reducer  42  (see  FIG. 14 ) that creates an airtight seal. A catheter syringe is inserted into the orifice reducer  42  to withdraw the required amount of color according to a formula. Upon withdrawal of the syringe, the opening in the orifice reducer closes firmly, preventing leakage and protecting the color from oxidation. Another container design (not shown) may be included for developer and hold approximately 33 oz. 
         [0081]    Referring to  FIG. 15 , an alternative embodiment dye container  100  is shown. The container includes a chamber  102  for containing a hair color product  104 . The chamber  102  is surrounded by a seal  106  that prevents exposure of the hair color product  104  to the air. A fitment bole  108  is included at a junction of the seal  106  to a valve  110  through which the hair color product  104  can be extracted. In one preferred embodiment, the fitment hole is 28 millimeters in diameter. In another preferred embodiment, the valve  110  includes a flip-top cap  112 , and may be sized for a 28-400 sized valve neck. The seal  106  includes a sloped portion  114  to encourage all hair color product  104  in the container  100  to reside near the valve  110  for extraction as the container  100  empties. In one embodiment, the container  100 , when empty, may be eight inches tall, six inches across at the top  116 , and four inches across at the bottom  118 . A hangar hole  120  is preferably included adjacent the top  116  for hanging the container  100 . When full, the container  100  may hold six fluid ounces of the hair color product  104   
         [0082]    Referring to  FIGS. 16-18 , a series of containers  100  are shown in a rack  122 . Preferably the rack  122  is sized to hold the customary number of colors (i.e., containers  100 ) used for a single hair color product line. As shown, the containers  100  are suspended in the rack  122  and oriented so that the caps  112  to the valves  110  are accessible to a user. As shown in  FIGS. 17 and 18 , respectively, the containers  100  may be suspended from clips  124  or may be suspended from hooks  126  in the rack  122 . 
         [0083]    Referring to  FIG. 19 , in one embodiment a twist lock  128  may be employed at the junction of the cap  112  and syringe  14  to ensure to locking connection that avoids spilling hair color product  104 . Referring to  FIG. 20 , alternatively, a self-sealing cap  130  may be used incorporating features such as a silicon valve closure  132 , thereby allowing the syringe  14  to withdraw hair color product  104  and be removed from the container  100  without spilling or dripping. 
         [0084]    Although preferred embodiments of the present invention have been shown and described, various modifications and substitutions may be made thereto without departing from the spirit and scope of the invention. For instance, in place of a luer-lock, another hermetically re-sealable locking connector may be used. Accordingly, it is to be understood that the invention has been described by way of illustration and not limitation.
