The Related Art Selection of the optimal colour shade is often a customer's chief concern in purchasing a cosmetic facial product. A number of companies in the industry have sought to render easier the selection process. Clinique and Clarion have installed comuters at sales counters for "0 use by the customer. Informacion on colour shade, oiliness and. other properties of a customer's skin are punched into the computer whi-h then. determines the company's most closely matching product.

25 Another point of sale technique has been that of custom blending. Two major companies, Prescriptives (division of Estee Lauder) and Visage (division of Revlon) begin a sale by manually evaluating a subject's skin colour. The salesperson then adjusts exiscing finished foundations so as to match the evaluated ski- colour. Unfortunately, there are many disadvantages in manual blending. The most obvious of these is that too much time is required for a match, sometimes 30-45 minutes. On many occasions there is a poor skin match, reproducibility is poor and extensive training is required of the salesperson.

2 Accordingly, it is an object of the present invention to provide an apparatus that can custom blend ingredients for delivery of a cosmetic product in a reduced period of time.

Another object of the present invention is to provide a custom blending machine for ingredients to obtain a cosmetic product that matches skin properties with a particular optimum reproducible formula.

A further object of the present invention is to provide a custom blending machine for ingredients to form a cosmetic product wherein the machine is suitable for placement in a department store and can readily be operated by a salesperson.

A still further object of the present invention is to provide a custom blending- machine for ingredients to obtain a cosmetic product that is highly accurate in 20 dispensing each of the ingredients.

These and other objects of the present invention will become more readily apparent through consideration of the following summary, drawing and detailed description which 25 follow.

SUMMARY OF THE INVENTION 30 A machine for custom blending of a colour cosmetic product is provided that includes: a mechanism for receiving operating instructions about a customer's optimal formula; 3 (ii) a plurality of dispensers each containing a cosmetic composition of a different colour; (iii)a mechanism for activating dosing to a common dosing chamber of certain selected ones of the cosmetic compositions and at certain concentrations as determined by the operating instructions; and (iv) a mechanism for delivering the dosed formula into a container to the customer as a colour cosmetic product.

Advantageously, the machine may also include a mechanism for regulating temperature, in particular, to maintain uniform viscosity of any liquid cosmetic compositions; changes in viscosity would bring about different dosing speeds thereby altering the accuracy of any dosed formula.

Suitable for such purpose is a combination of at least one heater and at least one fan. Best results are achieved 20 when temperature is controlled between 20 and 27 0 C preferably between 22 and 24 0

C.

The plurality of dispensers are preferably at least fivein number. There should be a separate dispenser for each of a set of monochromatic coloured cosmetic compositions which respectively are yellow, red and black coloured compositions. The fourth and fifth dispenser preferably contain identical compositions, each of which are white coloured. Additionally, there may be a sixth dispenser 30 that will contain a talc composition. A further dispenser may include an additive such as a sunscreen, a moisturiser, an oil absorbent organic polymer or combinations of these additives. Suitable sunscreens include titanium dioxide, oxybenzone, Parsol 1789® and ethylhexyl p-methoxycinnamate, as well as combinations thereof. Moisturisers may be selected from propylene glycol, polyethylene glycol, glycerin, water, mineral oil and comnbinat ions thereof. Oil absorbent organic polymers are represented by acrylic Polymers and PVP-Eicosene copolymers..

A series of pumps are necessary as a component of the mechanism for delivery of the dosed formula. These pumps assist in transporting the different cosmetic compositions from the dispenser to the common dosing chamber leading into a container for holding the customer's finished cosmetic product. Each dispenser will be associated with at least one pump. Advantageously, the first and second of the white-coloured composition-containing dispensers will each be associated with a pump of a different pumping capacity. One of these pumps will have a capacity ranging from about 0.01 to about 0.2 g/stroke while the second, pumnp will have a capacity ranging from greater than 0.2 to g/stroke. The smaller of the pumps is present to ***increase resolution and prevent a dosing error in the colour shades.. The larger of the pumps speeds delivery of the dosed formula because white is normally the largest component of the colour mix.

machine can also include an agitator for receiving the container when full with the dosed formula. and for vibrating the container to achieve uniform dispersion of all dosed cosmetic compositions. A preferred agitator is a unit powered by a motor whose shaft is fixed to a counterbalance weight. torque arm. A camn is attached to the arm; atop the cam is a cradle for receiving the formula dosed container. vibration is best performed at 3,000 to 4,000 rpm.

Advantageously, there will also be present a mechanism within the machine for diagnosing and reporting any failure to deliver proper amounts of the dosed cosmetic 5 compositions to the container. Among the types of failures diagnosed would be :hose resulting from a problem with insufficient cosmetic composition being within any one of the dispensers, an electrical circuit malfunction or even a pump malfunction. A telemodem may be incorporated within the machine for transmitting the aforementioned diagnosis and report via a telephone linkage to a central monitoring station remote from the machine.

As a further feature, the machine may include a labelling mechanism for applying a label co the container identifying the optimal formula dispensed therein. The label can be in the form of a bar code for identifying the particular optimal formula.

BRIEF DESCRIPTION OF THE DRAWING 20 Features and advantages of the present invention will more fully be appreciated .by reference to the drawing in which: Fig. 1 is a highly schematic perspective view of the 25 machine according to the present invention; Fig. 2 is a highly schematic cross-sectional plan view of the machine taken along line 2 2 of Fig. 1; and Fig. 3 is a highly schematic cross-sectional view of the machine taken along line 3 3 of Fig. 1.

DETAILED DESCRIPTION Fig. 1 illustrates the machine 1 of the present invention which is utilised for custom blending of a cosmetic product such as a facial foundation, rouge, nail polish or 6related colour product. The machine on a. f ront wall 2 thereof will have a window 4. allowing access to a dosing chamber 6. An operator can place an empty container 89, usually- an empty clear glass bttle, through the window into the dosing chamber 6. Container 8 will be. positioned to receive various cosmetic compositions from at least one, usually- four or more, nozzles Upon completion of fill into container the filled container is trans ferred to a blending chamber 12' whic. is accessed via window 14. within -front wall 2 of the machine..

Within blending chamber 12 is an agitator 16 that receives the filled container and vibrates the contents to achieve.

uniLform dispersion of all dosed cosmetic compositions..

1s A further useful. aspect of the invention. may be incorporation of a labelling device 18 for applying a.

.label- to the. container thereby identifying- the specLfiLc ~:dosed. formula. The label- may be in the form of.& bar 20 code..

Dosing chamber 6 and blending chamber 12 need not be.

separate spacial areas. For the highest efficiency, it may be desirable to combine the dosing and blending operation. within a. single chamber, Under such arrangement, the agitator 16 will. be positioned. directly underneath the nozzles rig.. 2 illustrates a cut-away front segment of machine 30 1. A. series of fixed pumps 20-25 are supported in an a :upper area of the machine. Each of the pumps are f luidly connected to a. series of six respective reservoirs identified as dispensers 20'-25, Reservoir- 20' and 21' each hold identical white-coloured cosmetic chemical composition A and Dispensers 22', 23' and each respectively contain a yellow, a red and a. black-coloured.

7 cosmetic composition identified as B, C and D. Each reservoir is fluidly connected to each respective pump.

Pump 20 has a different pumping capacity than pump each of which pumps are employed to transfer an identical white-coloured cosmetic composition. More particularly, the smaller pump 20 has a pumping capacity ranging from about 0.01 to 0.2 g/stroke, preferably from about 0.05 to 0.15 g/stroke. The larger pump 21 has a pumping capacity greater than about 0.2 to 0.5 g/stroke, preferably between 0.25 to 0.35 g/stroke.

A prograrmable logic controller 26 is positioned within machine I to receive operating instructions concerning the optimal formula to be dispensed. These operating instructions can be delivered electronically via a device that measures a customer's specific skin requirements or via mechanical input from a human expert assigning an optimal formula. The progranmable logic controller 26 is 20 electronically connected to a series of control relays 2__8 that activate movement of pumps 20-25.

Besides the coloured cosmetic compositions, there also is a talc composition E held within dispenser 25' comprising talc and a fluid carrier. Composition E is utilised as a facial coverage modifier and finish adjuster, i.e. matte or dewy finish, for foundation cosmetic products.

Particularly suitable as pumps are the ProMinent Garma/4 pumps available from Dosiertec-Inik GmbH.

Each of the dispensers 20'-25' has an associated liquid level monitor/switch device to identify the amount of cosmetic composition still remaining in the reservoir of the respective dispensers. Level indicator lights 30 connect to respective liquid level switches 8 These level indicator lights 30 are arranged along front wall 2 of machine I. Additionally, machine I will include a power switch 32 for electrically energizing the machine, a fill switch 34 for energising the dosing mechanism and a mixer switch for initiating rotation of spinner 16.

Fig. 3 best illustrates the te=erature regulating system within the machine 1. This system consists of a cooling fan 38 and heater 40 which are regulated by a temperature controller 42 having a high and low controlling mechanism, respectively 43 and 44-. Temperature must be maintained between 20 and 27 0 C, preferably between 22 and 24 0 C to maintain uniform viscosity of the liquid cosmetic compositions; changes in viscosity would bring about different dosing speeds thereby altering the accuracy of the dosed.

formula.

Within. the housing of machine is a mechanism 4A for 20 diagnosing and reporting any failure to deliver proper amounts of the dosed compositions to the container.

A

telemodem 48 is also present within the housing for transmitting a failure diagnosis report generated by mechanism 46 via telephone linkage to a central monitoring station remote 50 remote from machine 1. A further function of telemodem 48 is transmission of data concerning cosmetic composition usage, customer identification with a respective optimal formula and related data.

The foregoing description illustrates selected embodiments of the present invention and in light thereof variations and modifications will be suggested to one skilled in the art, all of which are within the spirit and purview of this invention.
