Patent ID: 11395535

Abstract:
A keyed refillable cosmetic dispenser for a stick cosmetic. The cosmetic dispenser has a cosmetic insert cartridge and a dispenser base with a matching key pattern combination. The insert cartridge has an inner body with a key pattern, an elevator cup, and a rotary extension and retraction mechanism for the elevator cup and a retained cosmetic. The key pattern of the insert cartridge can be a keyway in a keyway member of the inner body, and the key pattern of the dispenser base can be formed on a central column that forms a key member. The key patterns can be patterns of surface deviations, such as ridges and channels, that intermesh when the cosmetic insert cartridge is received by the dispenser base to produce a rotary driving engagement therebetween. A line of keyed cosmetic dispensers can be established by plural cosmetic dispensers with different key pattern combinations.
