Abstract: An opening/closing device for a container for pourable products is disclosed. The device has a perforable portion and a base combinable with the container at the perforable portion, and a cutting element having a sharp end arranged on its lower side. The base also has first and second passages located in a region of the base spaced from the upper surface of the perforable portion when the base is combined with the container and define a cavity between the lower surface of the region and the upper surface of the perforable portion. The cutting element is shaped to impede when it moves from a first position to a second position, allowing passage of the pourable product through the first passage from the container to the second passage through the cavity.

Abstract: An opening/closing device for a container for pourable products is disclosed. The device includes a collar combinable with the container at a perforable portion thereof, a moveable cap by a first guiding means, which are interposed between the cap and the collar, on the outer surface of the collar, and a cutting element constrainedly movable by second guiding means, which are interposed between the cutting element and the collar. Inside the collar, the device has pushing means for the cutting element, which are actuated by the cap during its first displacement on the outer surface of the collar, for promoting the displacement inside the collar of the cutting element in the direction of the perforable portion. The cap is also has a through hole for pouring product and a lid adapted to seal, or open, the passage of the through hole.
