Abstract: The embodiments disclosed describe a double opening beverage can lid system. The system includes a can lid having a pour panel associated with a pour opening and a vent panel associated with a vent opening. A tab is attached to the can lid. The tab includes a primary tab portion configured to open the pour opening, and a secondary tab portion configured to open the vent opening. A rivet hole facilitates attachment of the primary tab portion and the secondary tab portion to the can lid. A shelf is bent about 180° around a rear edge of the primary tab portion. The shelf blocks at least a portion of the secondary tab portion from contacting the vent panel.

Abstract: An improved beverage container of the type having a lid, a pour panel defined in the lid by a pour score and a vent panel defined in the lid by a vent score. A tab pivotally is mounted to the lid, wherein lifting the tab about a pivot in a lifting direction fractures the pour score and opens the pour panel. A secondary tab is carried by the tab, and is released into contact with the vent panel by lifting the tab to fracture the pour score, wherein pressing the tab in a direction generally opposite the lifting direction causes the secondary tab to fracture the vent score and open the vent panel. At least one anti-rotation member is disposed between the tab and the lid to prevent the tab from rotating about the rivet.

Abstract: Over the years there have been numerous attempts to improve the can lid oftentimes found on aluminum beverage can lids. The aims have traditionally been to reduce costs and improve performance. These aims have been accomplished through a variety of means, such as creating different formations within the can lid to reduce the amount of metal used while maintaining performance levels. Here, step portions are utilized between the annular countersink and the center panel of the can lid that cause a curvature of the center panel or to simply provide an angled inside wall. These formations, thus, reduce the amount of metal used while maintaining quality and yielding the desired performance.

Abstract: A preferred embodiment of the disclosed can lid has a center panel having a central axis that is perpendicular to a diameter of the outer rim, or peripheral curl portion, of the can lid, an annular countersink surrounding the center panel, an arcuate portion extending radially outward from the annular countersink, a step portion extending radially upward and outward from the arcuate portion, a first transitional portion extending radially outward from the step portion, a second transitional portion extending radially outward and upward from the first transitional portion, and a peripheral curl portion extending outwardly from the second transitional portion.

Abstract: A stay-on-tab container closure suitable for use on beverage cans and the like, said closure including an center panel with an downwardly displaceable tear panel, which, in one aspect, has a smooth upper surface having no visually perceptible contour features, and which, in another aspect, has low-relief contour features on its upper surface. Closures according to the invention have reduced stresses across the score defining the tear panel, thereby reducing the likelihood of stress-induced fatigue cracking which can lead to score failure when the container closure is joined to a can body and the resulting can is internally pressurized.

Abstract: The present invention describes a beverage can end which utilizes less material and has an improved internal buckle strength based on the geometric configuration of a chuck wall, inner panel wall and central panel, and which utilizes an inwardly oriented concave arch on the chuck wall with a radius of curvature between about 0.015 inches and 0.080 inches.
