Cosmetic stick holder with locking projection

A cosmetic stick holder, comprising:

• a piston that is adapted to support a cosmetic stick and which includes a lug;
• a slot sleeve which includes a longitudinal slot and an internal hollow within which hollow said piston is positioned;
• a screwing sleeve having a first end, a second end and a threaded groove, said screwing sleeve being positioned external to the slot formed in said slot sleeve such that said lug extends through said slot sleeve and into said threaded groove, and said slot sleeve including a foot part which extends away from the second end of said screwing sleeve;
• an outer cap member having a radial projection extending inwardly off of said outer cap member, said outer cap member further including an interior recess which receives said foot part, and said screwing sleeve being adapted for rotation with respect to said outer cap member and foot part such that, upon rotation of said screwing sleeve, said piston is longitudinally displacable with respect to said outer cap member;
• said foot part including locking means for releasably locking said foot part to said outer cap member;
• and
• said piston including an elastic locking projection which is dimensioned and arranged such that, when said piston is in a first position at the second end of said screwing sleeve, said locking projection is radially aligned with a locking opening provided in a wall of said foot part, and said locking projection having an internal spring force biasing said locking projection toward said locking opening, and said locking opening being shaped for locking engagement with said locking projection upon receipt of said locking projection in said locking opening, and said locking projection being dimensioned and arranged such that, when said releasable locking means is in locking engagement with said foot part and said piston is in said first position, said locking projection is placed in a non-engagement state with respect to the locking opening by the radial projection of said outer cap member.
