Abstract: A beverage package and a method of forming such a package defines a primary chamber containing an insert defining a secondary chamber. The insert has a seating in the form of a bore within which is received the lower end of a tube which is fitted to the insert. When the package is charged with beverage such as beer having gas in solution and sealed to form a headspace containing gas at a pressure greater than atmospheric, beer from the primary chamber fills the tube. The secondary chamber contains beverage and gas at a pressure greater than atmospheric and on opening the container the headspace de-pressurises causing beverage and gas from the secondary chamber to be ejected through the tube. A restricted aperture between the bottom end of the tube and an opposing wall of the insert causes froth to be developed in the beverage in the secondary chamber as the beverage flows into the bottom end of the tube. The frothy beverage then flows through the tube into the headspace.

Abstract: A container which has a top with two concentrically mounted lids, a first lid attached to and sealing the container and a second lid rotatably mounted to the first lid. The first lid has a weakened surface region formed by scoring, scribing or grooving. The first and second lids have nested embossments which are interengageable to apply a predetermined pressure to fracture the weakened region and form a pour aperture in the first lid when the second lid is rotated relative to the first lid. The second lid also has an aperture which is brought into an overlying relationship with the aperture in the first lid when the second lid is rotated relative to the first lid, thus allowing the contents of the container to be dispensed.

Abstract: The invention, relating to an easy-open metal container end, places a portion of the metal of the tear panel (12), in the region where a score stop otherwise would be located, under compression by forming a short coined depression or bead (40) in the tear panel, preferably in the public side, close to the score line (15) at least at the end of the vent region (35) opposite from the inner hook (16), which is located at the radially inward end of the tear panel score line. During initial opening or venting action, as the rivet (25) is lifted by initial tab motion, separation proceeds along the score line, beneath the nose (28) of the tab (27). The metal adjacent and in this coined depression tends to move partially underneath the metal on the opposite side of the score line from the coined vent bead. This action provides sufficient disruption or retarding of the score line separation or rupture, during venting, to confine such separation to the vent region until internal pressure is vented.

Abstract: A lid for a beverage container having a lifting tab is affixed to the lid by a staking member or rivet which serves as a fulcrum about which the tab pivots. The staking member is disposed radially from the center of the lid. A line of weakness defining a rupturable area in the lid is formed between the staking member and the periphery of the container, and defines a fruto-conical configuration so as to subtend an angle of at least about 90.degree.. The line of weakness is nearly completely continuous, but has one relatively small broken zone whereby the severed area circumscribed by the line is retained by the lid at the broken zone when the area is ruptured to create a hole along the line. The staking member is disposed radially from the center of the lid by at least about 2.5 mm., and the remaining surface area of the lid outside the rupturable surface area defined the line of weakness is greater than if a staking member were disposed in the center of the lid.

Abstract: A container (e.g., drawn and ironed) with modified end constructions is disclosed.

This tab includes at least one engagement section which is offset in relation to the center of the push-down tab and which is for interfacing with the consumer's finger (e.g., thumb) in a manner which facilitates a more effective opening of the push-down tab. The engagement section curves upwardly progressing toward the perimeter of the tab and therefore may be characterized as a generally ramped surface. In one embodiment, two such engagement sections are utilized and ramp upwardly in generally opposite directions. The integral end of the container body also includes a multi-stage center panel or dome for allowing stacking of filled containers.
