A capped barrel system for aging liquids includes a barrel and a barrel cap removably coupled to the barrel. The barrel includes: a plurality of wooden staves suitable for aging liquids, hoops for holding the staves together, a head coupled to the staves, and a bunghole formed in the head. The barrel cap includes: a lid including a top portion and a rim extending downwardly from the top portion. The rim includes an inner surface and a seal that defines at least a portion of the inner surface. The barrel cap further includes an opening formed in the top portion of the lid that is generally aligned with the bunghole and a closure removably positioned in the opening. When the closure is positioned in the opening, a gas tight coupling between the closure and the lid and a gas tight fit between the seal and the barrel form a gas tight environment between the barrel and the barrel cap.

A coating composition comprising a high molecular weight polyester, a trimellitic anhydride-polyol adduct and a curing agent is disclosed. The compositions are useful in coating food and beverage containers, particularly 2-piece cans formed by drawing and redrawing (DRD).

A container for storing a liquid or a solid may include a container body having a container side wall and a container bottom and a container lid having a pop top arm to pivot and cooperate with a weakened area to provide access to the interior of the container body. The container body may be formed from plastic and the container lid is formed from metal, and the container body may include a vertical neck. The container body may include a lip, and the bottom wall may include a center protrusion. The bottom wall may include a depression, and the bottom wall may include a radial extending depression.

A unit for bonding the container with the lid, made of plastic, designated especially for pressurised beverages, having a profiled rim of the container opening and a profiled rim of the lid, characterised in that the profiled rim of the opening (2) of the container (1) comprises a flange (3) formed around the said opening (2), extending outwards away from the side wall of the container, where the flange (3) has a top surface (4), side surface (5) and bottom surface (6) bonded to the external side surface of the container (1), and where formed on the top surface (4) around the opening (2) of the container (1) there is a rib (7) protruding above the surface (4), while the profiled rim of the lid (8) comprises a groove (9) formed on the bottom surface (10) of the lid (8) around its bottom edge, the groove (9) accommodating the said rib (7) which supports the lid (8) without touching on the top surface (4) of the flange (3), where there is an energy director (12, 13) formed on the bottom of the groove (9) or the top surface of the rib (7), which focuses ultrasonic energy in the process of ultrasonic welding of the rib (7) and the lid (8).

A container, such as a beverage or food can is provided, which includes a first sidewall, a second sidewall and a bottom portion extending between the first and second sidewalls. The material of the bottom portion is stretched relative to the first sidewall and the second sidewall to form a thinned preselected profile, such as a dome. The material of the container at or about the dome has a substantially uniform thickness. The container is formed from a blank of material, which has a base gauge prior to being formed. After being formed, the blank of material of the container at or about the dome has a thickness less than the base gauge. Tooling having a clamp bead, or a progressive clamp bead, for selectively forming a blank of material into a container, as well as an associated method are also disclosed.
