Title: Cosmetic powder dispensing device

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     This invention relates to cosmetic dispensing devices. More particularly, this invention relates to devices for dispensing makeup preparations of the type comprising naturally occuring mixtures of iron oxide based minerals and synthetic equivalents. 
     2. Description of the Prior Art 
     Naturally occuring iron oxide based mineral powders have been used as a form of cosmetic make-up. The powders used have included heavy concentrations of iron oxides. The mixture often contains minerals such as silicon, aluminum, calcium, manganese, magnesium and trace amounts of zinc, titanium boron, chromium, copper, vanadium, molybdenum, nickel and strontium existing in oxide, silicate and carbonate forms as occur in nature. The color is so deep and intense they cannot be applied successfully, as can other cosmetics, simply by dipping a finger, puff or brush into the powder and applying it to the skin. The result would be a &#34;war paint&#34; streak that would be most unattractive and discourage customers from purchasing the powder and attempting to apply it as make-up. 
     In the past, typical containers for the compound have included a spherical clay jar. The powder is held in place in the spherical jar with a cork. Consumers are advised to shake the jar with cork held firmly in place, so that some of the powder adheres to the cork. The excess powder is to be tapped back into the jar, and the cork used as a &#34;palette&#34; from which to apply the make-up. A puff, make-up brush or a cotton swab is dusted across the surface of the cork, and only a very small amount of the powder is to be picked up. In this way there are able to control the amount of powder, and therefore the intensity of color, they wish to apply to the skin. The control of intensity and amount of powder tends to be important with the use of this type of makeup. 
     Unfortunately, this container is too bulky and fragile for women to carry in their purses, or even in suitcases or make-up cases when traveling. Motion, such as in a purse or suitcase, could not only cause the container to break. The cork could work loose, spilling the powder into purse or case. This is extremely undesirable because of the intensity of the highly concentrated iron oxides and its staining properties as a raw, undiluted pigment. 
     These properties have discouraged women from carrying the clay jars of make-up around with them. Thus while they can apply the make-up at home, they cannot &#34;touch up&#34; during the day or evening as they can with competitor&#39;s blushers, bronzers, and similar makeup, almost all of which offer a convenient purse and travel size dispenser. This in turn tends to discourage recognition of the practicality of regarding the natural multi-purpose powder as a total makeup, i.e., a makeup that can be freshened during the day or evening. 
     It has been recognized by the consumers, distributors and manufacturers that the powdered make-up goes a long way and it need only be used very sparingly. From the point of view of the distributor or manufacturer, it would be desirable to limit the quantity of material sold in a single container. 
     Further, the material has a tendency to change color and tends to vary significantly in color, from a dark red to a distasteful purple black color, believed to be seasonal or resulting from the batch to batch variations of the mixture which is mined. Though this does not have a significant effect on the performance of the substance, the consumer is likely to be unnecessarily cautious about purchasing the product, thinking that there might be a lack of uniformity, and it would be advantageous to minimize the visual exposure of the product where unnecessary. 
     SUMMARY OF THE INVENTION 
     A cosmetic powder dispensing device in accordance with this invention generally comprises a volumetric chamber, for supporting an iron oxide based cosmetic powder in a confined volumetric region. A cover is provided for enclosing the chamber. The cover defines apertures for sparingly allowing passage of the cosmetic powder from the chamber. An element, including a substantially nonporous makeup adhering surface is movable from a position generally flush to the apertures to a position remote from the apertures. The cosmetic powder when disposed on the adhering surface may then be removed and applied to a wearer. 
     In a more specific example the volumetric chamber is thin and semicircular in configuration. The cover is generally flat and the adhering surface comprises a cork lamina. 
     Additional features in accordance with this invention includes a hinge movably coupling the adhering surface to the chamber so that the adhering surface is easily movable from a first position in contact with the aperture means, to a second position in which the hinged flat plate is movable to a position remote from the aperture means, so that a brush may be applied to remove the powdered material from the adhering cork lamina.

     DETAILED DESCRIPTION 
     With particular reference to FIGS. 1, 2, 3 and 4, an example of a cosmetic compact in accordance with this invention generally comprises a compact case 10 and a module 12, typically of plastic, preferably injection molded or vacuum formed, and affixed within the case 10. The case 10 comprises a circular lower shell 11 and a mating circular upper shell 13 hinged in movable relationship to the lower shell 11. The module 12 defines a thin volumetric chamber 14 including a pan 16 for confining a fine iron oxide based makeup powder to a generally thin areally disposed volumetric region. The thin volumetric chamber 14, in this example is generally semicircular, though it may have a rectangular form or other areal shape, such as shown by way of example in FIG. 5 and FIG. 6. A cover 18 mates with the module 12 spaced apart from the pan 16 and is fixed in place along a joint 20, such as by mechanical locking spines or other fastening means, so that the pan 16 cannot be refilled by the consumer. The cover 18 defines an areally disposed array of apertures 22 for sparingly allowing passage of an iron oxide based cosmetic makeup powder 24 disposed on the pan 16. Typically, about 0.02 grams of powder 24 may be loaded on the pan at the factory. The upper portion is sealed so that once the pan 16 is filled and the cover 18 locked or fixed in place, the cover may not be removed. Thus, the only manner in which the makeup powder can escape from the pan 16 is through the apertures 22. 
     A hinged plate 26 for providing an adhering surface has a substantially nonporous makeup adhering surface provided by a smooth cork lamina 28 glued to the plate 26 for receiving makeup powder 24 from the pan 16. The hinged plate 26 is movable from a first or closed position whereby the adhering cork surface 28 is in facing flush relationship to the cover 18 for receiving the pigmented makeup 24. The apertures are sufficiently small so that only a limited quantity of the powder can escape through the aperture array 22 yet large enough to allow sufficient material to escape to the adhering surface 28. The cover 18 is preferably stiff and planar, though it may have a curved configuration, providing the lamina 28 has a similar matable configuration to engage the cover 18 in facing generally flush relationship. 
     The plate 26 has a hinge 30 movably fastening the plate 26 to the module 12. Preferably, the plate is integrally molded with the module 12, and the hinge 30 is a &#34;live&#34; hinge and thus a thin flexible plastic portion. 
     The plate 26 is movable to a second or open position as best depicted in FIG. 3, in which the cork surface 28 is moved remote from the apertures 22 to allow the makeup powder 24 on the adhering surface 28 to be removed, such as by a brush, puff or cotton swab and applied to the wearers face. A latch 32 allows the plate 26 to be removably fixed in the second position by engaging a locking tab 33 on the module 12 so that the plate 26 will not move inconveniently when the makeup powder 24 is brushed off the cork surface 28. In addition, the latch 32 also engages a locking portion 34 on the module 12 adjacent the cover to allow the latch 32 to be locked in the first position, when the user desires to dispense the powder 24 on the cork surface 28. 
     As best viewed in FIG. 2, the module 12 comprises an annular portion 36 or loop having a bottom surface 38. The shell 11 of the case 10 has an inner surface 40 for receiving the annular portion 36, either in flat or specially mating relationship. The module 12 is thus joined to the case by gluing or sonic welding, for example, of the bottom surface 38 to the case inner surface 40. The height of the annular portion 36 defines the maximum thickness of the thin volumetric chamber 14. A transverse portion 42 of the module 12 partitions the case 10 and provides a sidewall 44 of the volumetric chamber 14. While a separate pan portion 16 is depicted in FIG. 2 and FIG. 3, it should be understood that the inner surface 40 may serve as the pan 16, and the module 12 may comprise simply an annular portion 36 having a generally rectangular cross-section and a transverse portion 42 dividing the annular portion 36 to partition the case 10. The bond in this situation should be sufficient to contiguously join the transverse portion 42 and the perimeter of the ring portion 36 defining the chamber 14, to render the chamber 14 impervious to the powder and thus maintaining the integrity of the confined volumetric chamber 14. The pan 16 is thus provided by the inner surface 40 of the case 10, the sidewall 44 of the transverse portion 42 and part of the annular portion 36. The living hinge 30 is integral with a substantial length of the transverse portion 42. 
     The module 12 and the transverse portion 42 define a second chamber 46 for storing a brush 48, for example. The module 12 may be dimensioned to fit within a standard circular or rectangular stock compact case. The shape of the annular portion 36 or loop, naturally, may take on a rectangular (rather than circular) or other perimeter to appropriately match the case used and define the desired size of the chamber 14, 46. FIGS. 5 and 6 depict different examples of the invention in which the case is rectangular or square. It should be recognized that the loop 36 is then also preferably of rectangular (rather than circular) configuration to define generally rectangular chambers. Glue or ultrasonic welding may be used to affix the module 12 in the hinged compact case 10. A mirror 50 may be affixed to the interior portion of the case 10 opposite the cover 18 so that it is conveniently exposed for use when the plate 26 is moved to the second or open position exposing the cork 28. 
     In use, the plate 26 is initially locked in the first or closed position, the latch 32 engaging the locking portion 34. The case 10 is shaken a few times, partly depending on the quantity of powder desired to adhere to the cork surface 28, the amount of shaking thus tending to control the amount of material passing through the aperture array 22 to the cork surface 28. The aperture array 22 causes the iron oxide based makeup powder to be dispersed on the cork 28 in a fairly regular manner. The brush 48 being exposed when the plate 26 is in the first position, is removed at this time. 
     The latch 32 is then unlocked from tab 34 and the plate 26 is moved to the second position, the latch 32 engaging the tab 33. The brush 48 is applied to the cork surface 26, removing the make-up powder which is applied to the face. Residual powder 24 is dispersed on the cover 18 about apertures 22 and may also be removed with the brush 48. 
     Thus, a powdered makeup compact has been provided which prevents spillage, applies evenly and conveniently to a cork surface, may be carried in a purse, avoids excessive visual exposure to appearance of powder color variations and is nonrefillable and convenient to use. 
     While the invention has been particularly shown and described with reference to preferred examples thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
