Abstract: A beverage can cap member (16, 100) is configured so that its exterior surface (28) extending radially inwardly from the rim (18) or rim forming portion (140) is substantially flat or continuous, or has a slight curve from a position adjacent from the rim (18) or rim forming portion (140). The cap member (16, 100) may have a countersink (160) which is filled with a filler material including a curable adhesive, an insert (180) of a natural or synthetic material or the like. The filler material increases the structural strength of the cap member (16, 100) to an extent that it can be made of a relatively thinner material and still complies with the minimum peaking pressure of the industrial standard.

Abstract: An invention that raises the tops of beverage cans at an angle that makes the drinking process easier, cleaner, more practical and safer (as in the case of drinking a soft drink while driving an automobile) in which one end of the can top that contains the scored oval opening is raised above the rim top of the can in a slanting wedge or circular shape that slants down to the opposite side allowing the can to be raised to a higher degree angle where it does not come in contact with the nose of the person drinking and reduces the angle the head is tipped backward as the drink is being consumed. Also the new top is raised in just the right amount so that it will fit into the concave bottom of an existing can without making contact, thus allowing for the stacking of cans on top of cans in six pack units. For twelve pack or larger packs, the invention includes spacers that allow for stacking packages on top of packages.

Abstract: An aluminum container is comprised of a base portion, a substantially vertical wall portion extending upwardly from the base portion, a transition portion extending from the wall portion, and a neck portion extending from the transition portion.

The upper end of the neck portion may also be chamfered. The aluminum container of the present invention may be combined with a threaded sleeve to form a receptacle. The sleeve has an outer surface and an inner surface. The outer surface has threads thereon and the inner surface has a taper complementary to the taper of the neck portion so as to form a friction fit with the neck portion. The sleeve may also have a notch formed in the periphery of its upper outside surface.

Abstract: The Split Can for Beverages is an advancement of the 12 ounce (oz.) beverage can having increased measurements throughout the entire can to satisfy primary improvements (additions) made to: (a) the top of the can and, (b) the interior center of the can. The Split Can for Beverages obtains on its top two smaller pull tabs positioned back to back (mirror images) as a thin piece (layer) of aluminum placed vertically in it's interior center forming a split. The Split Can for Beverages is a single aluminum can able to contain beverage products in a double embodiment having two sides (left and right) that are independent of each other functioning as two self-ruling usable single cans. In addition, because the Split Can for Beverages has two independent sides with their own set of opening mechanisms (pull tab, aluminum flap and opening) it maintains two different products comfortably, their brand names and designs.

Abstract: A dual aperture beverage can (1) consisting of a venting scored section (4) and a pouring scored section (6) on the container top (11). The container (2) is comprised of a container sidewall (9), a container top (11), and a container bottom (8). A tab (7) is employed to open both the venting scored section (4) and the pouring scored section (6), such that their respective apertures are revealed.

The tear panel geometry is asymmetrically skewed having a large radius of score curvature in a first outer quadrant of the tear panel to provide low resistance to opening the tear panel at the large radius. The tear panel has a radially outermost segment of the score located in a different quadrant of the tear panel.

Abstract: A beverage can with a bottom end, a top end, and a side wall extending therebetween. A first weakening score is formed in the top end, and a second weakening score is formed near the bottom end of the can. The beverage can has a first tab selectively displaceable between an initial position wherein the first tab is generally parallel to the can a displaced position wherein the first end pierces the can by causing the first weakening score to fail, thereby forming a first opening. A second tab with features similar to the first tab is positioned near the second weakening score. Specifically, the second tab is selectively displaceable between an initial position wherein the second tab is generally parallel to the can, and a displaced position wherein the first end pierces the can by causing the second weakening score to fail, thereby forming a second opening. Beverage may exit the can from either the first or second opening.

Abstract: The invention relates to a beverage can with a press-in closure (2) whereby a lid area is surrounded by a separating line (3) which can be pressed down into a partial area by means of an actuation tab (4) of a grip lug (7) that is fixed to the lid (5) by means of a riveted joint (6), and forming a hole (8) in the interior of the can for pouring out said beverage. According to the invention, the hole (8) can be covered with a perforated external lid (9) which is also attached to the lid (5) by means of a riveted joint (6).

Abstract: A tab top beverage can has a compressible drinking straw held between the can bottom and an upwardly extending detachable closed cavity formed in the can top. Detachment of the cavity by a pivoting tab top uncovers a straw access orifice through which the straw is projected by the force of a previously compressed corrugated spring section formed in the straw wall. A bulge located on the straw prevents passage of the straw from the can and facilitates extension of the straw. The tab is attached to the can top by outwardly projecting lips formed on upwardly projecting closed cavities defined in the can top. The cavities extend through openings in the tab and the lips extend beyond the opening perimeters to secure the tab to the cavities and top.

Abstract: A top lid for beverage cans with an opener integrated sanitary cover is disclosed. The sanitary cover 8 is designed to cover the area around the opening piece 3a defined on the top lid 50 by a depressed seam 3c, thus protecting the lip contact portion of the top lid 50 from atmospheric impurities and keeping the can sanitary during storage of the can. The sanitary cover 8 also has a reinforced opener part 13 which presses down the opening piece 3a and breaks the piece 3a along the depressed seam 3c when the cover 8 is levered up. The opener part 13 has a reinforcing rib 13b improving the stiffness of the opener part 13, and so the opener part 13 reliably breaks the opening piece 3a without failure even though a high pressure acts on the interior surface of the opening piece 3a.
