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.

The disclosed systems and methods relate to improved tamper-proof cases for securely storing and shipping products. A case can include a back panel, two sidewalls, an upper foldable section, and a lower foldable section. Each of the features of the case can be manufactured on a single sheet of material. The upper and lower foldable sections include panels having apertures for holding the top and bottom of a product, respectively. The upper foldable section includes one or more fasteners that secures the upper foldable section to the sidewalls. Once secured, the products cannot be removed from the case without showing evidence of the removal. The disclosed systems also provide a tear strip and/or a tear corner that can be used to release the products from the sealed case.

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.

A beverage can end has an arcuate panel wall and a chuck wall having a curved transition wall portion. Configuration of the seaming panel and panel wall is provided.

A method and apparatus for forming a can end in a forming press including positioning a sheet of material between an upper punch assembly and a fixed base assembly; cutting a can end blank from the sheet of material; clamping a peripheral portion of the can end blank; moving the upper punch assembly to clamp a central portion of the can end blank between an upper panel punch and a lower panel punch to define a central panel section positioned below an annular inner bead die located adjacent to the lower panel punch on the fixed base assembly; and extending the upper punch assembly to form an initial annular countersink radius next to the peripheral portion of the can end blank, with a substantially undeformed intermediate area extending between the initial annular countersink radius and the annular inner bead die.

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.

A can end including a center panel, an annular portion disposed about the center panel, a standard chuck wall disposed about the annular portion, and a curl extending radially outwardly from the standard chuck wall. The annular portion includes an enhanced annular countersink.

The present invention is directed to containers and packaging that incorporate novel tamper evident features. In particular, the containers of the present invention comprise newly designed tamper evident linkages, i.e., wedged fracture tabs. In addition, the present invention provides novel methods of improving tamper security of packages or containers by incorporating distinguishing printed graphics on the tamper evident component (e.g., frangible hinge, frangible tear strip, or wedged fracture tabs) of the present invention.

A mixed drink glass in which a shot glass affixed to the bottom of a mixing glass, wherein the volume of the mixing glass is larger than the volume of the shot glass.
