发明名称 Method of making lipstick samplers
摘要 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 gas pressure applied through the spindle to the aperture of the tip of the form, so as to blow off excess lipstick wax material therefrom. The form is allowed to cool so as to solidify the wax, and thereafter is fitted with a cover, removed, and suitably packaged.
