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: A beverage can lid with an easy opening feature comprises a scored lid, having a pull tab affixed to the lid by a rivet and an initial contact point on the lid which is pushed downward as the score line breaks at the puncture point adjacent the rivet. In the invention, the contact point is positioned in close proximity to the rivet to minimize the required lifting force, which is in proportion to the distance between the initial contact point and the rivet. Further, the puncture point is positioned close to the initial contact point so that the lifting force is also reduced. In one embodiment, the scoring radius at the puncture point is quite sharp so that the force required to break the seal at the puncture point is reduced. Also the gap between the puncture point and the end of the scored line is minimized to facilitate opening the lid. Furthermore, the pivot line is moved closer to the contact point to reduce the lifting force.

Abstract: A protective seal for beverage cans, etc. completely covers and seals the mouth contact area of the can, thereby protecting that area from contamination. The present seal comprises a thin, durable, impervious sheet applied to the top of the can surrounding the opening area, extending down the upper side of the can adjacent the top opening area for a short distance to cover the mouth contact area of the can. The seal is peripherally sealed to the can surface by a narrow strip of food grade adhesive. The tab attachment extension of the seal may include bushings, washers, etc. to provide clearance for the majority of the seal to pivot between the pop tab lever and can top, and/or may include a circumferential weakening line about the pop tab rivet to allow the majority of the seal to shear circumferentially to pivot about the captured rivet attachment portion thereof.

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: Carbonated beverages can have a substantially reduced concentration of water soluble materials derived from biaxially oriented thermoformed beverage containers. Such containers can comprise a permeant barrier and an active trap for water soluble materials that can be removed from the thermoplastic by extraction into the carbonated beverage. The improved container material comprises a blow molded thermoplastic polyester web comprising a compatible modified cyclodextrin material having pendent moieties or substituents that render the cyclodextrin material compatible with the container thermoplastic. The cyclodextrin material, after it is added to the polymer material, acts as a barrier and to trap extractable materials as they permeate through the thermoplastic polyester. The cyclodextrin molecule has a large center cavity having properties that increase the likelihood that organic molecules will be absorbed and trapped in the center pore.

Abstract: By lifting the other end of a grip, one end of the grip presses down a can lid portion, and a can opening is formed in a can upper wall while a score line delimiting the can lid portion is torn. The can lid portion is moved into the beverage can, an edge of the can lid portion, which is opposed to the other end of the grip is moved and contacted to a connection piece thereby to bend the connection piece along its score line. Accordingly, the continuously moving can lid portion pulls the connection piece toward the center of the beverage can, and a rotating member integrally connected to the connection piece is rotated about the line connecting the centers of a pair of projections. As the rotating member is rotated, an upper end of the rotating member is moved toward the can opening, and a bellows part of a straw, which is prevented from upward expanding, projects through the can opening and beyond the can upper wall. Therefore, it is possible to drink beverage through the projected straw.

Abstract: A container filled with a freezable mixture for use in refrigeration or temporary cooling purposes. The container of the invention is generally one of the common metal cylindrical containers or cans but may also include both plastic and glass bottles. Normally such containers are unsuitable for holding a freezable mixture due to the expansion of the freezing mixture causing the deformation or rupture of said container. By using a fully soluble eutectic mixture, such as propylene glycol and water mixed at a ratio of 20% propylene glycol, an ice slurry is formed at the temperatures normally present in home freezers. A small gas space is also needed for expansion and contraction of the container contents. When a can or other inwardly flexible container is utilized, a positive pressure within the container, relative to the external pressure, can be maintained with a gas charge.

Abstract: The drink can has an off-center opening in its lid, which is firmly connected to the body surface, and is fastened to the body surface by a flanged rim. A closure cap is arranged in a rotatable but non-removable fashion, on this flanged rim. The closure cap has two annular beads that are directed towards the lid, and of which the second annular bead surrounds an opening which has the same eccentricity as the opening in the lid. The first annular bead surrounds a closed region that comprises a sealing ring and a deformable bulge. In the closed state of the drink can, the sealing ring rests on the apex of an annular bead that surrounds the opening. The annular bead is therefore also arranged to be off-center, so that it surrounds the annular bead when the closure cap is in the appropriate rotational position. After the convex bulge has been pressed into a permanent concave position, the closure cap can be rotated, so that the opening in the closure cap aligns with the opening in the lid.

Abstract: An easy-open, reseable closure assembly for a beverage can (10) comprises a metal lid (12) and two threadedly connected molded plastic closure elements (40, 60) with engageable annular reseal surfaces (46, 76). The lid is scored (30) to define a circular tear panel (28) and a hinge (32). The spout element (40) is attached to the lid (12) with the bottom surface of the cap element (60) directly above and aligned with the periphery of the tear panel (28). Rotation of the cap element (60) by a user ruptures the tear panel and pivots the tear panel (28) downward about the hinge (32), providing a passage through the spout element (40) for pouring and driking. Initial rupture and rupture propagation of the tear panel (28) is controlled by the spacing of the cap element (60) from the tear panel (28) and their configurations. When the cap element (60) is replaced on the spout (40), reseal surfaces (46, 76) engage.
