Patent ID: 8117722

Claim:
An assembly device ( 1 ) associable with containers for logistical use, comprising: a principal locking element ( 5 ) irremovably connectable to an inner flap ( 2 a ) of a container realisable by folding a laminar element ( 10 ), said principal locking element ( 5 ) being designed to enable the coupling of said inner flap ( 2 a ) with at least one outer flap ( 2 b ) of said container at least partially superimposable on said inner flap ( 2 a ) of the container itself; a complementary locking element ( 6 ) activatable on said outer flap ( 2 b ) in operating conditions and designed to engage at least partially with the principal locking element ( 5 ); a principal active portion ( 5 b ) of the principal locking element ( 5 ), said principal active portion ( 5 b ) presenting mechanical restraining means extending towards the outer flap ( 2 b ) of the container in assembly conditions and designed to engage with the complementary locking element ( 6 ); and a complementary active portion ( 6 b ) of the complementary locking element ( 6 ), said complementary active portion ( 6 b ) presenting interconnection means extending towards the inner flap ( 2 a ) of the container in assembly conditions and designed to engage with the mechanical restraining means of the principal active portion ( 5 b ); sealing means ( 100 ) operationally active between the principal locking element ( 5 ) and the complementary locking element ( 6 ) and irreversibly configurable between a condition of first closure of the assembly device in which said sealing means bind the principal locking element ( 5 ) to the complementary locking element ( 6 ), and a condition of opening having occurred in which the principal locking element ( 5 ) is separated from the complementary locking element ( 6 ), said sealing means being separated by breakage, this corresponding to said condition of opening having occurred and including: a first irreversible hooking body ( 101 ) insertable into the principal locking element ( 5 ), a direction of said insertion being from the inner flap ( 2 a ) towards the outer flap ( 2 b ); and a second irreversible hooking body ( 102 ) formed in the complementary locking element ( 6 ) and designed to engage irreversibly with said first irreversible hooking body ( 101 ), this corresponding at least to the condition of first closure.
