Readily Detachable Lipstick Cartridges Patents (Class 401/DIG1)
  • Patent number: 5971351
    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.
