A substantially cylindrical, metal container (1) which container comprising an envelope surface wall (2), a top end and a bottom end (3), wherein the bottom end having a cavity which is formed by a circular concave, parabolic bottom surface (4) and a circular surrounding edge (5). A UHF RFID tag (6), comprising an integrated circuit (7) and an antenna (8), is arranged at the bottom end, wherein the antenna is located at a predetermined distance above the center of the bottom surface (4), such that the bottom surface reflects the antenna radiation.

A method of making a container having a tamper evident feature. The method comprises affixing a tamper evident tag to a bottom end so that the tag covers perforations in the bottom end. The tag may be a film-based tag incorporating a color shifting ink layer. When the container is opened, air enters the interior of the container, passes through the perforations and activates the color shifting ink layer.

A pressure resistant basic shell, easy open end and can with easy open end, wherein the basic shell consists of a can seaming portion, a countersink portion, a ferrule arc portion, an upward extension portion of ferrule and a center panel from periphery to center in the cross section; the countersink portion also consists of a sixth arc portion and a second straight portion, and the sixth arc portion and the second straight portion are connected in a tangent way, and the second straight portion and the ferrule arc portion are connected in a tangent way; the center of the sixth arc portion is located below the upper surface of the center panel. The break probability under the failure of pressure resistance is lowered to 0.05%˜2.5%, which significantly improves the safety of use.

A small volume metal beverage can is provided. The small volume metal beverage can has a diameter approximately equal to a convention, single serving beverage can, which is typically a diameter of between about 2.0 and 2.25 inches, and a length, significantly less than 2.0 inches but sufficient to contain the required volume of liquid for the small volume that comprises a typical single serving size, which single serving size may range from about 0.5 ounces to about 2.5 ounces. The small volume metal beverage can has a base and a top lid connected by a cylindrical sidewall. The base, top lid, and cylindrical sidewall forms a generally squat form taking a shape similar to an ice hockey puck. The top lid is generally formed with a removable opening, such as, for example, a pull tab or pop top. The small volume metal beverage can is stackable on a conventional beverage can.

Embodiments of the present invention relate to domed metal containers, and more specifically to pressurized metallic food containers with liquid nitrogen wells and various closure mechanisms. In some embodiments, the metallic food containers are thin-walled aluminum and are pressurized using liquid nitrogen to maintain strength and integrity. The container can have a nitrogen well to receive liquid nitrogen and keep the liquid nitrogen away from the food stuff packaged in the container. In various embodiments, the metallic food container comprises a domed bottom portion shaped and sized to nest with a food stuff packaged in the container. In some embodiments, the container is sealed with a tear away lid, a screw-on lid, or a metallic end closure double seamed to the container.

The present invention is directed to a smart metal, glass, paper-based, wood-based, or plastic packaging comprising at least one sensor or communication device, characterized in that a structural component of the packaging forms a component of the at least one sensor or communication device. In addition, the present invention is directed to a method for manufacturing a smart packaging is provided comprising the steps of manufacturing a packaging and constituting at least one sensor or communication device on or in the packaging, wherein a structural component of the packaging is taken for constituting a component of the at least one sensor or communication device.

A disposable container for food or beverage has a resistive heating element and a temperature sensor, where electric power is applied to the heating element which generates heat used to warm the container and its contents. A processor monitors the container and content temperature using a signal from the temperature sensor, and controls the temperature of the container and content using a switch circuit, so that the temperature is raised to a preset level, and then the electrical power is removed from the heating element.

A container can end includes a concave dome shape and may forgo a peripheral reinforcing bead around the center panel. The tab may also be curved. Tooling for forming the end and a corresponding method are provided.

An apparatus is disclosed and includes a can, which has an end wall incorporating a vent panel and a pouring panel, both panels being breakable and presenting a contour defined by a rupture line. A first actuation tab is externally affixed to the vent panel and manually and angularly displaceable, in order to be separated from the can jointly with the vent panel. A second actuation tab, which may be actuated after the vent panel is removed, is externally affixed to the pouring panel and provided with an end lower tooth, which is pressed against the rupture line of the pouring panel, when the second actuation tab is displaced so as to break, initially, the confronting spot region of the rupture line and, subsequently, to separate the pouring panel from said end wall.
