Abstract:
A handheld reusable multi-compartmental mixing and dispensing container for storing fluids separately therein before mixing. The proportions of the substances in a mixture are externally adjustable. The desired concentration is determined by test components attached to the container that sense various environmental and user specific factors. The amount of the adjustable substance to be added to a mixture is controlled by an adjustment wheel on the container. A single control button allows a user to choose what fluid substances are to be mixed and dispensed. A pressurized gas propellant in a replaceable canister moves the fluid around and out of the container.

CROSS-REFERENCE TO RELATED APPLICATION 
       [0001]    This application is a continuation-in-part of application U.S. Ser. No. 14/098,192, filed Dec. 5, 2013 for a Fluid Mixing And Dispensing Container. 
     
    
     BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention. 
         [0003]    The present invention relates to a hand-held reusable multi-compartmental mixing and dispensing container that permits a user to customize a mixture of fluids to be continuously dispensed. 
         [0004]    2. Description of Related Art. 
         [0005]    As science and medicine have added to our knowledge base, our understanding of the human body and effects of various environmental factors on it has advanced. We are adept at manufacturing and using various substances to enhance our appearance, protect us from the environment, improve our health, for example. The market is flooded with cosmetics and pharmaceutics. 
         [0006]    Currently most of these compounds come premixed, or, at most, in containers that allow one time mixing and dispensing in preset proportions. But, the human body and the environment are both dynamic. As a result, the cosmetic or pharmaceutical mixture being dispensed is rarely, if ever, specifically tailored to the individual and their environment. 
         [0007]    For example, sunscreens are produced with a specific preset amount of UV protective factors (SPF), emollients, and fragrances. As a consumer uses the product, the contents of the sunscreen being dispensed cannot be adjusted to take into account the changes in their skin color, the time of day, the weather, their individual preferences, or even whether it is more convenient to use a spray or a cream. Similarly, hair dyes are provided in a limited number of colors. A user is left to figure out what shade would work best with their hair color and type. It is not possible to do a match with any degree of accuracy. The containers used are not amenable to midstream changes in the relative proportions of the ingredients. The containers are not capable of dispensing a test sample. Dispensing of medicinal creams and lotions also presents a problem. Although dermatologists, and other physicians who treat skin conditions, most commonly prescribe the use of steroids, anti-fungal agents, antibiotic creams and emollients, there are no containers available that allow a patient to mix the cream and lotion at will, and dispense the mixture as a unit. 
         [0008]    As a result, a user does not experience the full benefits of a product simply because the mixture has not been tailored to meet their individual needs. They end up buying and using multiple products, which will be less effective. This has a negative impact on both the consumer and the environment. Plastic containers are a large contributor to landfill waste. Moreover, disposal of containers with product may be toxic. 
         [0009]    With regard to medicinal applications there is a significant risk that patients who must juggle multiple medications or creams will neglect one or more of the necessary components of their treatment plan. About 50-75% of patients are noncompliant with regard to their prescriptions. Only 20% of diabetics adhere to their insulin administration regime faithfully. This is very expensive in tell is of human health and the economy. In fact, it has been estimated that noncompliance with healthcare regimes “accounts for up to $100 billion in healthcare and productivity costs”. 
         [0010]    A dispensing and mixing container that takes into account the uniqueness of the each user, as well as the real-time environmental factors, providing personalized cosmetics, dermatologic creams, or administration of medications is needed. The current state of the art does not provide such a device. 
         [0011]    With regard to dispensing containers, there are various types available: 
         [0012]    U.S. Pat. No. 4,893,729 by Iggulden, Streck describes a bottle designed to dispense various mixtures of lotion and UV protective agents. The dispenser uses bores, does not have a self-retractable tip, is not powered by a pressurized gas canister, and does not give the user guidance as to the right amount of sunscreen agent or other compound that should be added. It cannot be personalized. 
         [0013]    EP1350739, US2009/0152300, U.S. Pat. No. 5,638,992, and WO2002/022467 all describe containers that mix two fluids. In EP1350739, separation is maintained by a breakable seal. In US2009/0152300, it is not. In U.S. Pat. No. 5,638,992, the inner pressurized container bursts causing mixing. In WO2002/022467, the compounds remain separate until dispensed and are not mixed. In none of these examples, is the user able to select the proportions of the compounds that will form a part of a final mixture. Mixing is done on a one-time basis. The amounts dispensed are not user-determined by test amounts. These prior art examples do not allow the product to be personalized. 
         [0014]    With regard to UV detection and measuring, various products have been devised. 
         [0015]    U.S. Pat. No. 5,589,398 by Krause et al. describes UV test strips that use a photoactive chromogenic substance to detect sunburn-causing UV radiation. These test strips do not take into account a user&#39;s skin color, are for one-time use only, are not paired with a sunscreen mixer and dispenser, and do not allow the user to choose between spray or cream. Furthermore, exposure to light causes the UV Fastcheck strips to lose their function. 
         [0016]    US2008/0259315 by Mersch utilizes titanium dioxide and resazurin to create an irreversible change upon UV exposure. This will allow a user to determine when they have been exposed to excess UV radiation. It will not advise a user, in advance, about the sunscreen protection necessary. It will not tell a user whether a sunscreen is effective. 
         [0017]    A UV sun strength warning band operates via photochromic dyes. The band does not take a user&#39;s skin color into account. 
         [0018]    Therefore, although there are various mixing bottles and test strips on the market, none of these products allow continuous precise repeated mixing and dispensing of varying proportions and amounts of the contained substances. None allow the substance to be altered by the user each time a mixture is dispensed, informed by measurements resulting from the use of test components that sense the environment and the user, and are affixed to the surface of the container as described hereafter. 
       SUMMARY OF THE INVENTION 
       [0019]    A multi-compartment container capable of mixing adjustable proportions of one substance with one or more other substances, and selectively dispensing varying amounts of the mixture via a user-selected system is provided. The desired proportions of substances within a mixture are determined according to input received from test components or other interfaces that sense various environmental and user-specific factors. 
         [0020]    The container holds various substances in separate compartments without allowing them to mix, preventing chemical interaction and extending shelf life. The compartments are refillable, making it possible to give the user a range of choices for what they would like to mix. For example, in the case of sunscreen, the user could have a choice between the type of UV filtering agent, the fragrance, the emollient content, and whether the mixture is dispensed as spray or cream. In the case of a dermatologic treatment agent, the user could choose the amount of emollient needed and, based on input from a treating physician, whether it is mixed with a steroid or, for example, an anti-fungal. In the case of medication for diabetes, a patient could be administered an individually tailored mixture of fast and slow-acting insulin mixed with diluent or another substance, based on factors such as their blood sugar and the time of day. 
         [0021]    A user can choose the proportion of each substance that will be mixed. This choice is guided by a system of environmentally and user-sensitive test components. For example in the preferred embodiment of the invention a built in UV graded test strip gives the user the ability to detect UV light and quantifies this information into a number, this number can be correlated with a strip that takes into account the individuals skin color and thus their natural defense against UV rays, adjusting the number provided by the UV graded test strip. From this the user can easily determine the adequate UV protection for their particular skin type and adjust the device accordingly via the adjustment wheel. A separate multifunction pushbutton further controls the amount and flow of the final substance to be extruded. 
         [0022]    Expulsion of the final mixture is accomplished by retractable nozzles. The push button, based on direction of operation, allows a user to select cream or spray, for example. Nozzles are designed to prevent spillage, or the buildup of debris. In order to be cost effective, the invention utilizes a replaceable gas cartridge with pressurized propellant to allow propulsion and proper function. A pressurized gas system with replaceable cartridge moves the mixture. Because there are no electronic components or batteries, the container of the present invention is both lightweight and environmentally friendly.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0048]    A preferred embodiment of the container  19  of the invention, that can be used to dispense sunscreen lotion or spray, is shown in  FIG. 1 . A clicking adjuster wheel  39  ( FIG. 13 ) on top of the container  19  allows a user to select the proportion of substance, such as UV light protectant for example, that is mixed in from an internal compartment  26  ( FIG. 3 ), with one of the other two substances stored in the two other internal compartments  27 ,  28  ( FIG. 3 ). The clicking adjuster wheel  39  allows precise control of the amount of substance added to a mixture, as will be explained hereafter. In the case of UV light protectant, a Sun Protective Factor adjuster arrow  55  points to an adjuster wheel symbol  58  that correlates with the Sun Protective Factor (SPF) being dispensed. The Sun Protective Factor adjuster arrow  55  also correlates with the number of clicks that the user perceives from a neutral position. An upper frictionless ring  56  separates the clicking adjuster wheel  39  from the container  19  allowing for smooth function during use. 
         [0049]    Container  19  holds the major internal components such as internal compartments  26 ,  27 ,  28  ( FIG. 3 ) and has openings for fill caps  24 ,  25  and  23  for those compartments. The container  19  is preferably made of duraluminum/zirconium for example, but other moldable equally durable materials, such as polymers may be used. Three threaded openings  24 ,  25  and  23  ( FIG. 3 ) pass through the front of the container  19  into their respective internal containers  26 ,  27 ,  28  ( FIG. 3 ) and are closed by slotted fill caps  59 . Each slotted fill cap  59  features a coin-width slot in its surface for easy opening. Substances are added to the internal compartments  26 ,  27 ,  28  after removing the slotted fill caps  59  from the threaded openings  23 ,  24 ,  25 . The contents, composition and nature of the various compartments can be adjusted, according to user and manufacturer preferences. In a preferred embodiment, the internal compartments  26 ,  27 ,  28  are filled with the following substances: compartment one  26  ( FIG. 3 ) contains a UV light protectant. Compartment three  28  ( FIG. 3 ) is filled with a cream based emollient. Compartment two  27  is filled with a fluid for spraying. 
         [0050]    Referring to  FIG. 1 , environmentally sensitive components are built into the container  19 . In a preferred embodiment, this includes a centrally located temperature and moisture-sensitive logo  20  that alerts the user when the container  19  has been exposed to environmental changes that could prevent optimal function. Test components in this device are located to one side of the temperature and moisture sensitive logo  20 . These can be adjusted to a manufacturer&#39;s or user&#39;s specifications. In the case of a container  19  for UV product, a graded multilayered UV light sensitive strip  31  is located along side of the temperature and moisture sensitive logo  20 . This graded multilayered UV light sensitive strip  31  is shown in more detail in  FIG. 6  and  FIG. 7 . 
         [0051]    Referring to  FIG. 7 , the base layer  60  of the graded multilayered UV light sensitive strip  31  is a non-thermoconductive light-reflective layer that besides providing some thermal insulation for the contents of container  19 , is combined with adhesive on the underside, that allows the UV light sensitive strip  31  to be securely fastened to the surface of the container. The next layer  32 , is a non-light-reactive reflective paint. The operational part of the strip is partially contained in this layer, which contains light sensitive symbol  34  made of light reactive reflecting paint. The next layer  61  is a graded UV light variable filter as found in UV shielded glass windows, films, and other applications. Although  FIG. 7  only shows one grade of the graded UV light variable filter  61 , an actual graded UV light variable filter has consecutive grades adjacent to each other forming a strip. When exposed to light, as the light intensity increases and more UV can propagate through a particular grade of the graded UV light variable filter  61 , the light reactive reflecting paint of the symbol  34  under that filter will react by contrasting with the non-light reactive reflecting paint  32 , creating a visible light sensitive symbol  34 . In summary, when the amount of UV light goes beyond the filter capabilities of the graded UV light variable filter  61 , light is able to reach the light reactive reflective paint of the symbol  34  and change its color. Contrast is enhanced by using nonreactive reflecting paint  32  in the same layer. The light sensitive symbol  34  displayed correlates with a wheel symbol  58  on the adjuster wheel  39  and to the number of clicks of the wheel needed to dispense the indicated amount of SPF. 
         [0052]    Referring again to  FIG. 1 , as well as  FIG. 7 , a sliding graded multilayered UV light sensitive strip cover  62  is used to block light from activating the light reactive reflective paint of the symbol  34  so that the light reactive reflective paint is kept safe from damages due to prolonged exposure, thereby increasing shelf life. If desired, the user can self-test the UV protection cream being dispensed by applying a small amount directly to the graded multilayered UV light sensitive strip  31 . This tells the user whether the sunscreen being dispensed is sufficient protection, based on chosen criteria such as day, time, skin color and location, for example. 
         [0053]    As shown in  FIGS. 1, 8 and 9 , a multilayer skin color match sticker system  35  is located directly adjacent to the graded multi layered UV light sensitive strip  31 . Layers may be removed to allow a user to match their own skin color with the color on the strip. Each skin color stickie  67  becomes progressively darker. Each skin color stickie  67  has numbers  33  along their length. The pack of stickies  35  are attached to the container  19  by an adhesive structure  68 . A user locates where the graded multilayered UV light sensitive strip  31  changes color causing the respective light sensitive symbol  34  to become visible. The user matches that light sensitive symbol  34  to the number “2” for example, located adjacent to this region on the skin color stickies  35 . This number on the skin color stickies will correspond to the number of clicks of the clicking adjuster wheel  39  ( FIG. 1 ) necessary for the container  19  to dispense the correct proportion of UV protective cream based emollient or spray for that specific user&#39;s skin color. 
         [0054]    The container is ergonomic as more readily seen from the rear ( FIG. 2 ). It includes a replaceable hand grip  36 . A frictionless ring  21  interfaces a removable base  22  that allows the internal cartridge  30  to be replaced. The replaceable silicone hand grip  36  ( FIG. 10 ) gives the user a steady grip on the container when discharging its contents. 
         [0055]      FIG. 12  shows the internal components of the container  19  and their spacial relationship to each other. The clicking adjuster wheel  39  at the top of the container  19  is fastened to an adjuster shaft  63  that is threaded to a conically-shaped flow-regulating valve  42 . The top of the container and the adjuster wheel  39  is shown in  FIG. 13 .  FIG. 14  shows a cross-sectional view of the placement of the internal components in container  19 . The function of the adjuster wheel  39  will be discussed more fully hereinafter. 
         [0056]    Referring again to  FIG. 12 , a pressure cartridge  30  inserted from the bottom of container  19  fits between internal compartment two  27  and internal compartment three  28 . The pressure cartridge  30  is held in place at the bottom of the container by a threaded wheel base  29 , and at the top by a threaded receiving end  64 . This is more clearly seen in  FIG. 14 . As the pressure cartridge  30  is threaded into the threaded receiving end  64 , it is locked into the high pressure propellant pipe  54 . 
         [0057]    When the push button  37  on the side of the container is in neutral position, propellant is only present in the high pressure propellant pipe  54 . Propellant flow is restricted by a ball bearing one way pressure valve  43 . A rubberized piston  44  and associated pistons  44   a  on the left and  44   b  on the right, pushes the ball bearing one way pressure valve  43  down into a closed position, simultaneously blocking the orifice leading to the high pressure propellant pipe  54 , preventing propellant flow. Pushing on the push button  37  moves the rubberized piston  44  allowing the propellant to flow. 
         [0058]    Referring to  FIG. 12 , the push button  37  that is located on the side of the container  19  controls the flow of the mixture to be dispensed, and whether the substance in internal compartment one  26  is to be mixed with that from internal compartment two  27  or internal compartment three  28 . An axle  65  goes through the push button  37  allowing it to rock around the axle. A main shaft  40  connects the top of the push button  37  to the rubberized piston  44  and associated pistons  44   a  and  44   b.  When the top of the push button  37  is depressed, the main shaft  40  and the rubberized piston  44  and associated pistons  44   a  and  44   b  are pushed to the left. If the bottom part of the push button  37  is depressed, the rubberized piston  44  and associated pistons  44   a  and  44   b  are pulled to the right. This push/pull action determines the direction and amount of propellant flow through the lower one way check valve  46   a  or lower one way check valve  46   b.  The propellant will enter either internal compartment two  27  through one way check valve  46   a  or internal compartment three  28  through internal check valve  46   b.  This pushes the substances in the containers into their respective intake pipes, right hand intake pipe  47  or left hand intake pipe  48 . The push button  37  returns to the neutral position upon release, as a result of the action of spring  66 . Details of this system are more clearly shown in  FIGS. 15A-15D  and will be more fully discussed hereinafter. 
         [0059]    A rubberized piston  44  and associated pistons  44   a  and  44   b , as shown in  FIG. 14  and in more detail in  FIG. 16A  is an important element of the container  19 . The rubberized piston  44 ,  44   a,    44   b  is housed within the piston cylinder  49  containing multiple apertures. A threaded conically-shaped flow-regulating valve  42  at the top of the cylinder  49  and two one way check valves  46   a,    46   b  at the bottom, control the flow. The upper aperture threaded conically-shaped flow-regulating valve  42  allows propellant to enter internal compartment one  26 , as shown in  FIGS. 14 and 16B . The lower left one way check valve  46   a  allows gas to enter internal compartment two  27 . The lower right one way check valve  46   b  allows gas to enter internal compartment three  28 . As explained above, the ball bearing one way pressure valve  43  is between the lower one way check valves  46   a,    46   b.  While the push button  37  is in a neutral position, the ball bearing one way pressure valve  43  blocks the flow of propellant because it is depressed by the rubberized piston  44 . 
         [0060]    If a user wants to dispense a mixture from internal compartments one  26  and internal compartments two  27 , the bottom part of the push button  37  is depressed as shown in  FIG. 15B  so the main shaft  40  is pulled, moving the rubberized piston  44  and associated pistons  44   a  and  44   b  to the right. Movement of piston  44  opens the left-hand side valves, including the threaded conically-shaped flow-regulating valve  42  and the lower one way check valve  46   a.  The propellant is allowed to flow, as shown in  FIG. 14 . The propellant travels down into internal compartment two  27 , displacing its contents into the left hand mixing compartment  51 . At the same time, the propellant also moves through the threaded conically-shaped flow-regulating valve  42  and displaces substance from internal compartment one  26  through one way check valve  45   a  into mixing compartment  51 . The displaced substance from internal compartment one  26  correlates to the amount of propellant allowed to enter internal compartment one  26  by the threaded conically-shaped flow-regulating valve  42 . As shown in  FIG. 14 , a specified amount of substance from compartment one  26  is moved into the left hand mixing compartment  51  through one way valve  45   a.  The resultant mixture moves to the mixing pipe  69  that has a spiral insert  41  to help further mix the substances before they are extruded via the self-retractable pressure nozzles  38  ( FIG. 15D ). 
         [0061]    If a user wants to dispense a mixture from internal compartment one  26  and internal compartment three  28 , the top part of the push button  37  is depressed so the main shaft  40  is pushed, moving the rubberized piston  44 ,  44   a  and  44   b  to the left as shown in  FIG. 15C , opening the right-hand side valves, including the threaded conically-shaped flow-regulating valve  42  and the lower one way check valve  46   b,  so that propellant is allowed to flow. The propellant travels down into internal compartment three  28 , displacing its contents into the right hand mixing compartment  50 . Simultaneously, propellant travels upwards through the threaded conically-shaped flow-regulating valve  42  and enters internal compartment one  26  at the flow rate fixed by the valve  42 . This continuously displaces a fixed amount of substance, such as a UV-protective agent into the mixing chamber  50  through one way check valve  45   b,  as long as the top of button  37  is pushed. 
         [0062]    A detailed illustration of the structure of rubberized piston  44  and associated pistons  44   a  and  44   b  are shown in  FIG. 16A . A detailed illustration of the threaded conically-shaped flow-regulating valve  42  is shown in  FIG. 16B . 
         [0063]    After the mixture of the two substances moves through the mixing pipe, the mixture is ejected via one of two self-retracting pressure nozzles  38  located near the top of the container  19 , as shown in  FIG. 15D  and  FIG. 18 . As the mixture enters the dispensing area, it moves through a spring-loaded aperture-containing plate  70 . The mixture causes pressure to build up on the inside of a cone  71 , which is attached to the spring-loaded aperture-containing plate  70  by an ejector shaft  72 . This results in the cone  71  moving forward allowing the pressurized mixture to be expelled, until the pressure is equalized. When there is no pressure on the spring-loaded aperture-containing plate  70 , the spring causes the cone  71  to go back to its initial position and the cone  71  seals off the opening. A detailed view of the various valves and components of the self-retracting pressure nozzle is shown in  FIG. 18 . Please note that there are seals (not shown) located between all moving components and pressurized areas to prevent leakage. 
         [0064]      FIG. 17  illustrates the various operations possible with the dispensing container of the present invention, as the result of the organization and structure of the key components. 
         [0065]    A pressurized cartridge  30  dispenses propellant under control of a threaded conically-shaped flow-regulating valve  42 . A rubberized piston  44  controls the path of travel of the propellant throughout the device. 
         [0066]    The rubberized piston  44  and associated pistons  44   a  and  44   b  are controlled by moving it left or right by a main shaft  40 . Pushing the main shaft  40  ( FIG. 15C ) causes the pressurized propellant to flow through the threaded conically-shaped flow-regulating valve  42  to internal compartment one  26  and through a one-way check valve  46   b  to internal compartments three  28 . Internal compartment one  26  may contain a UV protectant. Internal compartment three  28  may contain a spray fluid for mixing with the UV protectant. 
         [0067]    The UV protectant from internal compartments one  26  is moved out of the internal compartment in an amount determined by the user by adjusting the clicking adjuster wheel  39  ( FIG. 14 ). The spray fluid from internal compartment three  28  is moved out of the internal compartment through the right hand intake pipe  47  into a right hand mixing compartment  50 . The mixture moves out of the right hand mixing compartment  50  through a mixing pipe  68  to a self-retractable pressure nozzle  38 , where it is expelled in a UV spray. 
         [0068]    If the main shaft  40  connected to the rubberized piston  44 ,  44   a,    44   b  is pulled ( FIG. 15B ), the rubberized piston  44 ,  44   a,    44   b  moves to the right. This causes pressurized propellant to flow through the threaded conically-shaped flow-regulating valve  42  to internal compartment one  26  and through the lower one way check valve  46   a  to internal compartment two  27 . Internal compartments one  26  may contain the UV protectant. Internal compartment two  27  may contain a cream based emollient for mixing with the UV protectant. 
         [0069]    The UV protectant from internal compartment one  26  is moved out of the internal compartment in a predetermined amount, as determined by the user, by adjusting the clicking adjuster wheel  39  ( FIG. 19 ). The cream based emollient from internal compartment two  27  is moved out of the internal compartment, through the upper one-way check valve  45   a,  into a left hand mixing compartment  51 . The mixture moves out of the left hand mixing compartment  51  through a mixing pipe  69  to a self-retractable, pressure nozzle ( FIG. 15D )  38  where it is expelled as a UV cream.
