Abstract: A method of manufacturing disposable, single-use lipstick samplers by means of a dipping process. In a preferred form, a reservoir containing molten lipstick wax material is provided, and a spindle which is disposed above the reservoir is advanceable toward and retractable away from the reservoir. A plastic cup-shaped form having an apertured tip is applied to the spindle, which is thereafter advanced so as to submerge the tip of the form into the molten liquid wax material. The spindle and coated form are then removed from the reservoir, and a vacuum is applied through the spindle to the aperture of the tip of the form, so as to draw lipstick wax material therefrom and into the interior of the spindle. The form is allowed to cool so as to solidify the wax, and thereafter is fitted with a cover, removed, and suitably packaged.

Abstract: An apparatus and method for custom blending and fabricating lipstick to the specific demands of individual customers. The present invention provides a kit which enables a user to blend various pigments to arrive at a very specific shade, and then blend the desired shade with a specific base to result in a desired consistency of lipstick, and which also allows the blended bases and pigments to be heated to a liquefied form and poured into a mold for hardening. Upon cooling and hardening, a conventional lipstick case can be attached to the lipstick for removal from the mold and use by the customer. The present invention therefore not only allows a user to quickly attain the specific shade and consistency of lipstick desired, but also eliminates the time consuming and unsatisfactory process of visiting multiple stores having expansive inventories of variously shaded and textured lipsticks.

Abstract: Disclosed is a method and apparatus for shaping a top surface of a product, such as an antiperspirant or deodorant product, to have a compound-curved shape. The apparatus includes at least one cutting blade which moves inward and outward in a second direction while the product passes by in a first direction perpendicular to the second direction, such that the cutting blade cuts the top surface of the product to have a desired profile in the first direction. The cutting blade itself can have a desired profile along a third direction perpendicular to the first and second directions, to impart to the top surface of the product a desired profile in the third direction. A plurality of cutting blades can be used, to incrementally remove product material to form a final shaped product surface. The product cut off in forming the shaped surface can be reclaimed for re-use.

Abstract: A process of producing a solid cosmetic includes continuously repeating the steps of feeding a cosmetic base containing a powder and an oil as main ingredients into a heating cylinder from a hopper, causing the cosmetic base to be injected into a mold by forward motion of a screw or plunger, and cooling the thus-injected cosmetic base to solidify in the mold.

Abstract: Molded cosmetic products, containing a uniform ultra glossy wet look surface finish are molded in polymeric molds or mold inserts whose inner walls have been modified by subjecting them to a plasma treatment. This allows an improved release of the products and imparts the wet look surface finish to the cosmetic products.
