The closure member (30) is free of any axial retention members with both containers (12, 14) such that when the upper container (14) is rotated in a first rotational direction (F1), the closure member translates downward until falling into the first product cavity (22).)

1. A device (10, 40) for packaging two products (A, B) separately and dispensing the resulting mixture (M) at the first use,

the device (10, 40) comprises: a lower container (12, 42) defining a first product chamber (22, 52) containing a first product (A); and an upper container (14, 44) defining a second product chamber (24c, 54c) containing a second product (B), the containers (12, 42; 14, 44) being rotatable one relative to the other without moving axially,

wherein said device (10, 40) further comprises a temporary closure member (30) configured for closing the open end (24b, 54b) of the upper container (14, 44) prior to the first use and comprising a cylindrical skirt (32) surrounding said open end (24b, 54b) and a plug (34) connected to said cylindrical skirt (32), said cylindrical skirt (32) being provided on its inner cylindrical surface with an inner thread (32a) cooperating with an outer thread (24e) provided on the upper container (14, 44) and on its outer cylindrical surface with first anti-rotation means (32b) cooperating with second anti-rotation means (18d, 48d) provided on the lower container (12, 42) for preventing the closure member (30) from interacting with the lower container (12, 42) and the device is characterized in that,

the closure member (30) is free of any axial retention members with both containers (12, 42; 14, 44) such that when the upper container (14, 44) is rotated in a first rotational direction (F1, F1'), the closure member translates downwardly until falling into the first product cavity (22, 52).

2. The device (10, 40) according to claim 1, wherein the closure member (30) comprises a bridge (34B) of hinge-forming material connecting the plug (34) to the cylindrical skirt (32) and at least one connection (34c) of breakable material, such that when the upper container (14, 44) is rotated in a second rotational direction (F2 ') opposite to the first rotational direction (F1'), the closure member is translated upwardly until the breakable connection (34c) is broken by a force, causing the plug (34) to pivot about the bridge (34B) of hinge-forming material between a first position in which the open end (24B, 54B) is closed to a second position in which the open end (24B, 54B) is open, such that the second product (B) flows to the first product cavity (22) of the lower container (12, 42), 52).
