A pour spout that is sufficiently rigid to be prevented from breaking due to ultrasonic vibrations during welding and that is readily separated from a packaging container being broken down, and a packaging container with the pour spout. The pour spout includes a cylindrical sidewall and a disk-like flange extending outwardly from one end of the sidewall. The flange has a to-be-cut portion that is a recess arranged annularly, and a rib disposed at an annular projection or at the to-be-cut portion.

A package closure (10) comprising a neck (12), a cap (11) for closing an opening of the neck (12), and a folded portion (21) connecting the neck (12) and the cap (11), wherein the neck (12) has an axis (A) and is formed with a tubular portion (16) and an inward projecting sealing flange (18), wherein the cap (12) is formed with a top portion (13) for covering the opening of the neck, and an axially extending sealing ring (19) to interact with the sealing flange (18) to form a seal between them. The neck (12), the cap (11) and the folded portion (21) are formed in a single integrated piece. The cap (11) is further formed with an axially extending wall (14) arranged radially outside of the tubular portion (16) of the neck (12), wherein the folded portion (21) connects the wall (14) of the cap (11) with the neck (12). The top portion (13) of the cap (11) is connected to the wall (14) through a breakable notch (23) and a hinge (24), wherein the top portion (13) is openable by tearing along the notch (23) and folding along the hinge (24). Disclosed is also a method for producing the package closure (10).

A one-piece polymeric closure includes first and second closure portions. The first closure portion includes a first polymeric top wall portion and a first polymeric annular skirt portion. The first annular skirt includes a first set of splines on an inner surface thereof and knurls formed on an exterior surface thereof. The second closure portion includes a second polymeric top wall portion with a pull ring and a second polymeric annular skirt portion The second annular skirt portion includes a second set of splines on an outer surface thereof, an internal thread formation, and a locking ratchet band. The first and second sets of splines are configured to interact with each other when the polymeric closure is in a closed position. The polymeric closure opens by flipping the first closure portion with respect to the second closure portion via a hinge.

There is described a spout for a package having a designated pour opening and being filled with a pourable product. The spout comprises at least a collar extending along a longitudinal axis, carrying a pouring outlet at a first axial end and an inlet opening for the pourable product at a second axial end and delimiting a flow channel for the pourable product extending between the pouring outlet and the inlet opening a closing element configured to interrupt a fluidic connection between the pouring outlet and the inlet opening. The closing element is interposed between the inlet opening and the pouring outlet and is rupturably fixed to an inner surface of the collar.

There is described a lid-spout assembly for a package. The lid-spout assembly comprises at least a spout having a collar carrying a pouring outlet, a coupling ring arranged around a portion of the collar, a lid and a hinge element hinging the lid to the coupling ring. The lid is controllable between at least a closed configuration and an open configuration. The lid-spout assembly comprises an interaction assembly partially associated to the collar and partially associated to the lid and being designed such to determine a threshold force needed to be exceeded, in use, in order to control the lid from the closed configuration to the open configuration.

A spout is for a package having a designated pour opening and being filled with a pourable product. The spout comprises a collar carrying a pouring outlet, an inlet opening and a closing element controllable between an active position in which the closing element interrupts a fluidic connection between the pouring outlet and the inlet opening and an inactive position in which the closing element is configured to allow a fluidic connection between the pouring outlet and the inlet opening. The closing element comprises a peripheral portion contacting prior to a first control of the closing element from the active position to the inactive position an inner surface of the collar along an initial contact portion. The inner surface comprises a main surface portion extending from the initial contact portion towards the pouring outlet and an auxiliary surface portion extending from the initial contact portion to the inlet opening.

A closure assembly (10) for plastic containers comprises a neck insert (12) and a closure cap or plug (26). The closure assembly is configured to be fixed and sealed to the container either by insert-molding or by ultrasonic welding.

A spout comprises a collar carrying a pouring outlet and an inlet opening for the pourable product and delimiting a flow channel. The collar comprises an inner surface delimiting the flow channel. The inner surface comprises at least a main surface portion and a slanted surface portion. The main and slanted surface portions are such that a first intersection of a first intersection plane with the inner surface results in at least one first one-dimensional curve, a second intersection of a second intersection plane with the inner surface results in at least one second one-dimensional curve. The first and second one-dimensional curves each comprise respective first and second portions lying on respectively the slanted surface portion and the main surface portion. The first one-dimensional curve is superimposable on the second one-dimensional curve such that at least the respective first portions and the respective second portions are superposed.

A container 10 for mixing and dispensing of material having a liquid receptacle 14 and a plunger 18. The receptacle 14 has a front portion 36 and the plunger 18 has a forwardly projecting sharp protrusion 42 having a shaft 72 which terminates in a sharp outer end 78, 82. Upon the plunger 18 being depressed the sharp protrusion 42 pierces a front portion 36 of the liquid receptacle 14 and the liquid in the receptacle 14 is pushed hydraulically through the front portion 36 into a main chamber 17. Thus the liquid contacts material in the main chamber 17 to form a mixture. The plunger 18 can continue to be depressed so as to break the front portion 36 of the liquid receptacle 14 away and then push the material in the main chamber 17 towards a dispensing nozzle 26. The main chamber 17 has a frangible membrane 22 at a distal end 13 thereof which is hydraulically broken by pressure applied from the material in the main chamber 17 so that the material can be dispensed from the container 10. The container 10 is particularly envisaged for use with mixing and dispensing of dental materials.

A resealable, tamper-evident, low cost plug for an edible oil (or other foodstuffs) container is contemplated. The plug includes a single-piece, hinged construction with the base panel having a removable diaphragm revealing an opening that is sealed by structure provided on the hinged panel. Smooth pouring features may also be incorporated within and/or beneath the opening.
