Method of forming a lip stick, comprising the steps of:
- a. arranging on a first support (11) a mold (2) made of elastic material, which comprises a casting cavity (4) equipped with an opening (5),
- b. centering a cup (3) on the opening (5) of the casting cavity (4), wherein said centering takes place through a second support (8) equipped with a seat (8A) with at least one guide (9) for the centering of the cup (3), the second support (8) being centered with respect to the mold (2) or with respect to the first support (11), wherein the cup (3) defines a longitudinal axis and includes a plurality of projections (3A) extending from an internal perimeter of the cup perpendicular to the longitudinal axis, each of the plurality of projection (3A) including one or more stiffening ribs 80 spaced apart from a sidewall of the cup and extending in a longitudinal direction along the longitudinal axis,
- c. subsequent to centering the second support (8) with respect to the mold (2) or with respect to the first support (11), pouring a molten cosmetic product through the cup (3) into the casting cavity (4),
- d. waiting for the molten cosmetic product to solidify in the casting cavity (4) to form the lip stick,
- e. extracting the lip stick (7) from the cavity by grasping the cup (3), the cup (3) being configured to hook onto a lipstick device (10).
