Lip stick machine for lips

Lip stick machine (1) comprising a first tubular body (2) on which a second tubular body (3) is rotatably fitted, the first tubular body (2) having at least one first guide (2A) and the second tubular body (3) having at least one second guide (3A), a cursor (5) equipped with at least one first pin (5A) housed both in said first (2A) and in said second guide (3A), so that a mutual rotation of the first tubular body (2) with respect to the second tubular body (3) causes an axial translation of the cursor (5), a closure (6) equipped with a tubular projection (9) configured to couple with a first free edge (11) of the first tubular body (2) when the closure (6) is fitted on the machine (1), characterized in that the second tubular body (3) has a first annular groove (13) open on a second free edge (12) of the second tubular body (3), the first tubular body (2) having a flange (14) at the first free edge (11), the flange (14) being positioned inside said first annular groove (13) so as to load a lateral surface (15) of the annular groove (13) when the closure (6) is fitted on the machine, a surface (16) of the first body (2) facing the tubular projection (9) having a second groove (18) in correspondence with said flange (14), the second groove (18) having a C-section, the closure having a reduced diameter surface (6A) configured to cooperate with a free end of the second tubular body (3) where the annular grove (13) is located, so that, when the closure (6) is in position, the flange (14) and the part of the tubular body (3) where the annular grove (13) is located are sandwiched between the tubular projection (9) and the reduced diameter surface (6A).
