Patent ID: 11708191

Abstract:
Opening/closing device (1) for a container (100) for pourable products having at least one pierceable portion (101), said opening/closing device comprising a collar (2) combinable with said container at said pierceable portion, a cap (3) provided with a lower portion (3a) and displaceable on the outer surface (2a) of said collar (2) in a constrained and only rotatable way by first guiding means (40) interposed between said collar (2) and said lower portion (3a), and a cutting element (5) movable in a constrained way inside said collar (2) by second guiding means (60), which are interposed between said cutting element (5) and said collar (2) to sever said pierceable portion, said device (1) further comprising pushing means (7) for said cutting element (5) which are driven by said cap (3), at least during its first displacement on said outer surface (2a) of said collar (2), such as to aid the displacement of said at least one cutting element inside said collar in direction of said pierceable portion, said cap (3) comprising at least one lid (3b) rotatably constrained with respect to said lower portion (3a) of said cap (3) between an opening position (PI) and a closing position (P2), and vice-versa, characterized by comprising releasing/engaging means (10) between said lid (3b) and said collar (2) such as to allow the opening/closing of said lid depending on the rotation angle reached by said cap (3) with respect to said collar (2), after the first displacement of said cap on said outer surface (2a) of said collar (2), said opening of the lid being allowed only when said cap reaches a rotation angle such as the pouring is handier for the user, and once the lid has been reclosed, said lied being lockable in stable position with the collar by rotating the cap with respect to the collar so that to reach a rotation angle different from that in which said lid is rotatable with respect to the lower portion of the cap.
