  • Patent number: 4820070
    Abstract: A dispenser for stick type products such as cosmetics and the like which tend to shrink with age includes a novel cup or godet to prevent the stick from moving axially out of the cup. The interior wall of the cup includes a plurality of spaced axially disposed and radially inwardly projecting ribs of dove-tail cross-section. These ribs bite into the stick and function as dove-tail locks to prevent the outer surface of the stick from moving axially and rotationally with respect to the cup, even if stick shrinkage takes place. A screw type dispenser is also described as typical of the types of dispenser with which the cup may be used.

  • Patent number: 4635659
    Abstract: The present invention relates to an Improved Mascara Applicator which is used to apply mascara to eyelashes. The Improved Mascara Applicator of the present invention incorporates a unique applicator design which contains a multiplicity of rows of closely spaced and evenly spaced applicator flukes which permits each eyelash to be evenly coated with mascara. The unique applicator design also incorporates a series of communicating channels between the multiplicity of rows of applicator flukes in order to permit mascara to flow from one row to the next. This built in mascara reservoir channel design feeds each of the mascara coating flukes with mascara in order to assure proper mascara flow to each eyelash. This unique design further eliminates the requirement of frequently dipping the mascara applicator into a pool of mascara to replenish the applicator.The present invention also relates to an improved method of manufacturing the head of this mascara applicator.
