CONTAINER WITH A LID ATTACHED TO A THREADED CLOSURE MECHANISM
FIG7 is a vertical cross-section according to an alternative embodiment in which the retainer element is a plastic deformation made in the wall of the tubular skirt towards the inside of the first insertion passage
FIG7 shows an embodiment similar to the one described above, but in which the retainer element 50 is a plastic deformation of a part of the tubular skirt 42 located below the annular flange 21 of the lid 20, with the receptacle 10 being in the vertical position.

['1. A container with a lid attached to a threaded closure mechanism, the container including: • a receptacle (10) provided with a mouth (11) including a receptacle opening (13), an annular mouth surface (14) surrounding said receptacle opening (13), and a thread (12) externally surrounding said mouth (11); • a lid (20) with a front side and a back side, said lid (20) including an annular perimetral flange (21) which, in a closed position, is superimposed on the annular mouth surface (14) of the receptacle (10), and at least one central rib (22) protruding from the front side of the lid (20); • a sealing ring (30) arranged and held between the annular mouth surface (14) of the receptacle (10) and the annular flange (21) of the lid (20); • a closure mechanism (40) movable between a closed position and an open position, the closure mechanism (40) being formed by a tubular skirt (42) with a first open end and a second end closed by means of an annular disc (41) attached along its outer perimeter to the tubular skirt (42), said tubular skirt (42) being provided with an engagement configuration (43) complementary to the thread (12) of the receptacle (10); wherein ∘ the tubular skirt (42) surrounds and defines a first insertion passage (44) the size of which is equal to or greater than the external size of the annular flange (21) of the lid (20) and the depth of which is greater than the thickness of the annular flange (21); and ∘ the annular disc (41) surrounds and defines a second insertion passage (45) in the center thereof, the size of which is smaller than the size of the first insertion passage (44) and the external size of the annular flange (21) and greater than or equal to the size of the at least one central rib (22) of the lid (20); wherein in the closed position the annular flange (21) is inserted into the first insertion passage (44) and in contact with the annular disc (41) of the closure mechanism (40), the at least one central rib (22) is inserted into the second insertion passage (45), the tubular skirt (42) is arranged around the mouth (11), and the engagement configuration (43) of the closure mechanism (40) is coupled to the thread (12); characterized in that : a retainer element (50) is connected to the closure mechanism (40) constricting the first insertion passage (44) thereby retaining the annular flange (21) attached to the closure mechanism (40) preventing the removal of the lid (20); or a retainer element (50) is connected to the closure mechanism (40) constricting the second insertion passage (45), portions of the retainer element (50) being inserted into portions of side grooves (24) located in areas of the at least one central rib (22) of the lid (20) located at two different halves of the lid (20), thereby retaining the at least one central rib (22) attached to the closure mechanism (40) preventing the removal of the lid (20).']
