The present invention relates to a tube closure assembly. The assembly includes a tube head that includes a neck and a closure liner sealing said neck, and a cap that includes a punch provided with at least one tooth. The one or more teeth are configured to peripherally cut said closure liner. The cap is configured to transition from an open flush position, in which the one or more teeth are flush with said closure liner, to a perforation position, in which the one or more teeth perforate the closure liner, then from the perforation position to an end-of-travel position allowing partial cutting of the closure liner, the transition from the perforation position to the end-of-travel position being carried out with an angular rotational range below 360°.

The present invention relates to an assembly for the closure of a tube. The assembly includes a cap that includes a punch adapted to cut a seal. The seal is adapted to seal a neck of a tube head. The cap is configured to be fixed to the neck in a first position, known as the standby position, and a second position, known as the use position. The assembly also includes a ring movably fixed to the cap. The assembly is configured to allow the passage from an extended position, with the aim of the punch being protected by the ring in the standby position of the cap, to a retracted position, with the aim of the seal being pierced by the punch in the use position of the cap, a passage of the assembly from the extended position to the retracted position being effected by a sliding of the cap through the ring.

A pack having an opening region provided in the top of the pack which forms a pouring opening after it is cut through by an applied pouring element, the pouring element including a base body, a cutting element arranged movably therein, and a screw cap, the screw cap being used for first opening of the pack by actuating the cutting element and for reclosure, and the opening region having a weakened line. The weakened line has a round first section and a second section. The first time the composite pack is opened by moving the cutting element, the weakened line is cut in the first section and tears in the second section.

The invention relates to an assembly for closing a tube, said assembly comprising a tube head that has a neck (10) and a cap (30), said assembly defining a guide path, a thread and a thread portion (11) allowing the cap (30) to be positioned on the neck (10) by cooperation with the guide path and the thread, said assembly comprising a first (24) and a second (25) stop element for said thread portion (11), said stop elements (24, 25) being angularly spaced apart and defining a passage (26) between the guide path and the thread, said assembly being configured to allow axial displacement of the thread portion (11) through the passage (26) with a non-return effect produced by at least one (24) of said stops.

The invention relates to an assembly for closing a tube, said assembly comprising a tube head (3) that has a neck (10) and a closing cover (5) for closing said neck (10), the assembly further comprising a cap (30) which is provided with a piercing element (7) designed to perforate said closing cover (5), the neck (10) and cap (30) being configured such that the cap (30) is guided on the neck (10) into a closed position in which said piercing element (7) has perforated the closing cover, passing via an intermediate position in which the piercing element (7) has finished piercing said closing cover (5), and this also produces a material deformation which seals the closure, said assembly being configured such that the intermediate position is passed through prior to the material deformation which seals the closure.

An assembly for closing a tube, said assembly comprising a tube head (3) provided with a neck (10) and a cap (5) closing said neck (10), said assembly further comprising a stopper (30) comprising a punch (7) adapted to perforate said cap (5), said neck (10) and said stopper (30) being configured to guide the stopper (30) to a closing position in which said punch (7) has perforated said cap (5), characterized in that said cap comprising a lateral skirt (23) provided with at least one notch (60) opening radially, said neck comprising a protrusion (61) configured to cooperate angularly with said notch (60) to block a withdrawal of the cap (30), once said cap (30) is in said closing position

The invention relates to an assembly for closing a tube, said assembly comprising a tube head (3) that has a neck (10) and a closing cover (5) for closing said neck (10), the assembly further comprising a cap (30) which is provided with a piercing element (7) designed to perforate said closing cover (5), the neck (10) and cap (30) being configured such that the cap (30) is guided into a closed position in which said piercing element (7) has perforated the closing cover (5), said piercing element comprising one or more teeth (50) for cutting through the closing cover (5), which extend from a free edge (80) of the piercing element (7), at least one angular portion (81) of said free edge (80), referred to as the passage portion, being configured to remain in the neck (10) when in said closed position.

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.

An opening device configured to be applied to packaging for pourable products comprises: a pouring spout defining a pouring opening through which to pour, in use, the pourable product; a cap configured to engage and disengage the pouring spout to respectively close and open the pouring opening; a closing element closing and/or sealing the pouring opening, formed in one piece with the pouring spout and connected to the pouring spout by a breakable connecting portion configured to break during first opening of the opening device; the closing element comprising a protruding portion extending through the pouring opening and connected to the cap; and tamper-evidence device fitted to the pouring spout and initially connected to the cap by at least one breakable connecting bridge configured to break during first opening of the opening device; wherein the cap is hinged to the tamper-evidence device thereby being permanently tethered to the pouring spout.
