providing in the coupling element ( 20 ) a first hollow end ( 26 ), suitable for coupling with the supplying end of the container ( 10 , 30 ), and a second end ( 27 ), closed and suitable for being punched;
providing on the coupling element ( 20 ) a first guiding means ( 21 ) for guiding the movement of the connecting means ( 6 ) movable from the first position, close to the second end ( 27 ), to the second position, close to the first hollow end ( 26 ), and vice versa along a first degree of freedom;
providing on the connecting means ( 6 ) an engaging means for engaging with the protection means ( 9 ) so as to integrally move along a second degree of freedom, different than the first degree of freedom, and first matches for the first guiding means ( 21 ), so as, during the integral movement of the protection means ( 9 ) and of the connecting means ( 6 ) according to the second degree of freedom, the first matches of the connecting means ( 6 ) move from the first position to the second position along the first guiding means ( 21 ) of the coupling element ( 20 );
providing on the coupling element ( 20 ) a second guiding means ( 23 ) for guiding the removal of the protection means ( 9 ); and
providing on the protection means ( 9 ) second matches ( 13 ) corresponding to the second guiding means ( 23 ), so that the removal movement of the protection means ( 9 ) corresponds to the movement of the protection means ( 9 ) in respect with the connecting means ( 6 );
making the container, the protection means or the coupling element malleable;
wherein the coupling of the coupling element ( 20 ) with at least one among the container ( 10 , 30 ), the protection means ( 9 ) and the connecting means ( 6 ), occurs when the container ( 10 , 30 ), the protection means ( 9 ) or the coupling element ( 20 ) is still malleable;
wherein the first guiding means of the coupling element ( 20 ) comprise a first thread, and wherein the first matches of the connecting means ( 6 ) comprise a first counter thread, on an inner surface ( 12 ) of the connecting means ( 6 ) and corresponding to the first thread;
wherein the second guiding means of the coupling element ( 20 ) comprise a second thread, with a direction opposite to the one of the first thread and wherein the second matches of the protection means ( 9 ) comprise a second counter thread ( 13 ), on an inner surface of the protection means ( 9 ) and corresponding to the second thread;
wherein at least one among the first counter thread and the second counter thread ( 13 ) is realized by pressing respectively the connecting means ( 6 ) and the protection means on the coupling element ( 20 ) while the connecting means ( 6 ) and the protection means ( 9 ) are still malleable.
2. The method for the realization of an opening and liquid supplying system ( 100 ) according to claim 1 , further comprising the following steps:
providing the connecting means ( 6 ) integral with a needle holder ( 4 ) equipped with needle ( 1 ) suitable for punching the second end ( 27 ) of the coupling element ( 20 ), when the connecting means ( 6 ) are in the second position;
providing a needle guard (C) for the needle holder ( 4 ),
embedding at least a portion of the needle guard (C) in the protection means ( 9 ) whene protection means ( 9 ) is still malleable.
3. The method for the realization of an opening and liquid supplying system ( 100 ) according to claim 1 , wherein the first guiding means are realized by pressing the connecting means ( 6 ) while still malleable on the coupling element ( 20 ).
4. The method for the realization of an opening and liquid supplying system ( 100 ) according to claim 1 , further comprising the following step:
realizing the second guiding means of the coupling element ( 20 ) by pressing the protection means ( 9 ) while still malleable on the coupling element ( 20 ).
5. The method for the realization of comprising an opening and liquid supplying system ( 100 ) according to the method of claim 1 further comprising a pre-filled container ( 10 , 30 ).
6. The method according to the claim 5 , further comprising the following step:
