A container with a lid attached to a threaded closure mechanism, the container including:
- a receptacle provided with a mouth including a receptacle opening, an annular mouth surface surrounding said receptacle opening, and a thread externally surrounding said mouth;
- the lid with a front side and a back side, said lid including an annular perimetral flange which, in a closed position, is superimposed on the annular mouth surface of the receptacle, and at least one central rib protruding from the front side of the lid;
- a sealing ring arranged and held between the annular mouth surface of the receptacle and the annular flange of the lid, the sealing ring including a central opening delimited by an inner edge of the sealing ring;
- the closure mechanism movable between a closed position and an open position, the closure mechanism being formed by a tubular skirt with a first open end and a second end closed by means of an annular disc attached along its outer perimeter to the tubular skirt, said tubular skirt being provided with an engagement configuration complementary to the thread of the receptacle;
- wherein
- the tubular skirt surrounds and defines a first insertion passage the size of which is equal to or greater than the external size of the annular flange of the lid and the depth of which is greater than the thickness of the annular flange;
- and
- the annular disc surrounds and defines a second insertion passage in the center thereof, the size of which is smaller than the size of the first insertion passage and the external size of the annular flange and greater than or equal to the size of the at least one central rib of the lid;
- wherein in the closed position the annular flange is inserted into the first insertion passage and in contact with the annular disc of the closure mechanism, the at least one central rib is inserted into the second insertion passage, the tubular skirt is arranged around the mouth, and the engagement configuration of the closure mechanism is coupled to the thread;
- a retainer element constricts the first insertion passage thereby retaining the annular flange attached to the closure mechanism preventing the removal of the lid, the retainer element comprising:
- a plastically deformed portion of the tubular skirt producing a bulging towards the inside of the first insertion passage, or
- an elastically deformable element attached under elastic strain into the tubular skirt, inserted by pressure into the first insertion passage, the elastically deformable element having portions thereof fitted in openings or seats of the tubular skirt fixing the position of the retainer element inside the first insertion passage;
- or
- an elastically deformable element attached under elastic strain around the tubular skirt with portions of the elastically deformable element introduced into the first insertion passage through openings of the tubular skirt.
