An automatic opening and closing device for a container comprises a closure flap within the container and a pivot arm with a weighted portion. When the container is in a first position, the centre of mass of the weighted portion is offset horizontally and vertically from the pivot point of the pivot arm and acts to bias the closure flap to close an opening in the container. When the container is rotated in a first direction to a second position, the weighted portion causes the pivot arm and closure flap to rotate relative to the container in a second direction opposite to the first direction, to bias the closure flap away from the opening. In the first position, the weighted portion is offset vertically by a greater distance than it is offset horizontally. A locking mechanism may also be provided, which is operable to the user to keep the container closed even when tilted.

A container closure device includes a closure unit with a closure part for opening and re-closing the container opening multiple times, and an operating device with an operating part for actuating the closure part, wherein the operating part is rotatably disposed on the closure part and can be rotated from a locked position into an unlocked position. The operating part includes a first and a second locking portion configured such that, in the locked position, the two locking portions extend beyond the container opening up to an opening limiting region delimiting the container opening, and that, in the unlocked position, at least one of the two locking portions does not extend beyond the container opening up to the opening limiting region delimiting the container opening.

A container lid assembly including a rotational and axial guide feature extending radially from an interior surface of a lid sidewall. The rotational and axial guide feature is designed to provide axial translation and retention of a cap or other accessory when the cap (accessory) is rotationally engaged with the lid sidewall. The cap and lid can include an interface that creates a liquid and gas impervious seal therebetween. The seal can be provided between a bottom surface of the cap and the top surface of the lid, a feature of the sidewalls of the cap and the lid, or any other sealing interface. The lid can include a score line defining a tear panel, wherein the tear panel can be opened when the score line is fractured. The score line can be fractured using a stay-on-tab, an incisor, a shearing force, etc.

A closure for containers providing a seal when closed. A pull tab lifted to open provides a venting action, and a pour opening. A sanitary platform covers a drinking area around the pour opening. Closure contains electronic device components triggered to engage a user in games of chance through the use of a cellular phone.

An easy-opening end closure that may also be reclosed, suitable for joining to a container. A cover panel is bonded around its perimeter to an end panel with a rotatable lever interposed between them. To open the closure, a user applies force to the rotating lever to move it axially around an attachment point and progressively debond the seal perimeter. In this process, latching mechanisms ensure uni-directional movement of the lever relative to the shutter and joining of the two components at the end of the rotational sweep.

An apparatus is disclosed and includes a can, which has an end wall incorporating a vent panel and a pouring panel, both panels being breakable and presenting a contour defined by a rupture line. A first actuation tab is externally affixed to the vent panel and manually and angularly displaceable, in order to be separated from the can jointly with the vent panel. A second actuation tab, which may be actuated after the vent panel is removed, is externally affixed to the pouring panel and provided with an end lower tooth, which is pressed against the rupture line of the pouring panel, when the second actuation tab is displaced so as to break, initially, the confronting spot region of the rupture line and, subsequently, to separate the pouring panel from said end wall.

A pop top lid encloses a cylindrical fluid container. The pop top lid includes an end shell having an off-center scored line defining a tear panel; and a stay-on tab assembly riveted through a central portion to the end shell for rotation. An aperture point is attached to a central portion and rotatably positioned proximate to an inner edge of the scored line. A shearing edge is attached to the central portion and radially extending behind the aperture point. An actuator portion is attached to the central portion opposite to the aperture point, is liftable as a first-degree lever to form an aperture at the scored line with the aperture point, and is rotatable to insert the shearing edge into the aperture shearing the scored line to remove the tear panel from the end shell.

A metallic container end closure is provided that generally comprises a primary pour opening and an extended or secondary score which is opened with a secondary tool to form a secondary pour opening. The fact that a secondary tool is required allows the secondary score to be shallower, and thus more secure than deeper scores that are openable by finger pressure alone. Once the secondary tool is used to fracture the secondary score, a secondary pour opening is produced adjacent to the primary pour opening to form a larger opening. A user may insert materials such as ice or oranges through the enlarged pour opening.

An easy-opening end closure that may also be reclosed, suitable for joining to a container. A cover panel is bonded around its perimeter to an end panel with a rotatable lever interposed between them. To open the closure, a user applies force to the rotating lever to move it axially around an attachment point and thereby progressively debonding a substantial portion of the bond perimeter. The closure incorporates means for equilibrating pressure in the internal headspace of the container with the outside ambient for improved pouring.
