Claim 18:
19. A refillable container for a stick type cosmetic product, comprising:
a base assembly;
a cap detachably attached to the base assembly;
a refill cartridge;
wherein the base assembly comprises an outer shell, a limiting member, a button member, a sliding member and a spring;
wherein the outer shell of the base assembly includes at least one sidewall, a bottom wall, an opening at a distal end of the outer shell, and defining a cavity therein;
wherein the refill cartridge is configured to be detachably received at least partially within the cavity of the outer shell of the base assembly;
wherein the cavity of the outer shell houses the limiting member, the button member, the sliding member and the spring;
wherein the limiting member is coupled to an inner surface of the outer shell;
wherein the limiting member comprises at least three grip projections that extend downwardly from an annular ring like structure of the limiting member;
wherein the button member comprises a button portion and a pair of arcuate portions opposite to each other in a circumferential direction, wherein the pair of arcuate portions each includes a first end connected to the button portion and a free second end;
wherein the button portion is exposed to an outer side through an aperture formed in the at least one sidewall of the outer shell of the base assembly, while the pair of arcuate portions lies within the cavity of the outer shell;
wherein the pair of arcuate portions comprises at least three grip grooves which are configured to receive the corresponding at least three grip projections of the limiting member so as couple the button member to the limiting member;
wherein the sliding member includes least one slide groove which is configured to engage a corresponding slide guide protrusion formed on the inner surface of the at least one sidewall of the outer shell;
wherein the limiting member includes a positioning groove that extends axially on the outer surface of the limiting member;
wherein a concave cutout formed on the outer surface of the limiting member substantially opposite the at least three grip projections in a circumferential direction;
wherein the inner surface of the at least one sidewall of the outer shell of the base assembly comprises a longitudinal positioning rib which is configured to engage in the positioning groove of the limiting member to orient the limiting member such that the at least three grip projections of the limiting member circumferentially opposes the aperture of the outer shell and the concave cutout of the limiting member aligns with the aperture of the outer shell;
wherein the pair of arcuate portions of the button member detachably fits around a portion of the refill cartridge to lock the refill cartridge within the base assembly;
wherein when the button portion is pressed, the pair of arcuate portions of the button member deforms to release the refill cartridge from the base assembly; and
wherein when the refill cartridge is released from grip of the pair arcuate portions of the button member, the spring biases the sliding member to slide upwardly and push the refill cartridge in a vertical direction towards the opening at the distal end of the outer shell of the base assembly.
