A container (1) for biologic samples, comprising:
- a lower receptacle (2), having a side wall (20) provided with a first external thread (21) and terminating with a first circular mouth (22),
- an upper receptacle (3) designed to contain, before activating the container (1), a toxic liquid (LF) or considered as such, having a side wall (30) being provided with a second external thread (31) and terminating at one end with a second circular mouth (32) and at the other end with a closed base (33);
- a connecting sleeve (4), comprising:
- a lower part (41) having a lower side wall (43) with a first internal thread (44) engaging the first external thread (21) of the lower receptacle (2),
- an upper part (42) having an upper side wall (45) terminating with a free end (46) and including a first internally smooth band (47), an internally threaded zone (48) with a thread (70) engaging the external thread (31) of the upper receptacle (3), and a second internally smooth zone (49) near the free end (46);
- a transversal septum (40) separating said lower part (41) from said upper part (42) and being provided with a central vent opening (55), made in a chimney element (65), and with a plurality of transfer openings (51) made, for a transfer of the toxic liquid (LF), in a peripheral area (52) with respect to the central vent opening (55),
- characterized in that
- in said connecting sleeve (4):
- said peripheral area (52) of the transversal septum (40) is internally delimited by a first circumferential projection (53) orthogonally protruding in the upper part (42) of the connecting sleeve (4), the first circumferential projection (53) being adapted to create a tight seal with said second circular mouth (32), when the upper receptacle (3) is completely screwed into the upper part (42) of the connecting sleeve (4), and
- a circumferential rim (54), being at least partial, projects inward near the free end (46) of the upper side wall (45), the circumferential rim (54) having an inner diameter adapted to create an undercut in said second internally smooth zone (49) in the upper part (42) of the connecting sleeve (4),
- and
- said upper receptacle (3) comprises, concentrically with said second circular mouth (32):
- in said second internally smooth zone (49) near the free end (46) a radial ring (63) having an outer diameter greater than the internal diameter of said circumferential rim (54) of the connecting sleeve (4), and
- a stem (56) leaning inwardly from said closed base (33) of the upper receptacle (3), the stem (56) being able to fit tightly into the central vent opening (55) of the transversal septum (40) when the upper receptacle (3) is completely screwed, and to create an air passage when the upper receptacle (3) is partially unscrewed up to said circumferential rim (54).
