A can container includes a can barrel and a can bottom; the can bottom includes a dome part which is concaved toward an inner side of the can container along a direction of a can axis at a center, and also includes an annular convex part which projects toward an outer side of the can container so as to shape an annular support part on an outer periphery of the dome part: and the dome part has a central dome part which is positioned on the can axis and has a set radius of curvature, and an outer peripheral dome part which is shaped continuously on an outer side of the central dome part, has a center of curvature positioned on the can axis, and has a radius of curvature smaller than the radius of curvature of the central dome part.- - -

A can container includes a can lid including a disk-shaped panel portion in which a circular score line defining a region for forming a drinking opening is formed on an outer peripheral edge side, a groove portion connected to the outer peripheral edge of the panel portion and recessed from the panel portion; and a can body including a cylindrical body portion, a fixing portion fixed to the flange portion, and a tapered portion provided between the body portion and the fixing portion and having a diameter reduced from the body portion toward the fixing portion, wherein a ratio between a diameter of the score line and an inner diameter of the body portion is 0.6 to 0.8.

A method for producing a container having a threaded wide neck, includes steps of: heating a preform having a polyester body, on which there is mounted a polyolefin sleeve positioned next to an area of the body corresponding to the wide neck of the container; introducing the heated preform, with the sleeve, into a mould having the footprint of the container, including a threaded area having the footprint of the wide neck; injecting a pressurised fluid into the preform in order to form a blank of the container including a lower portion including the wide neck with a thread formed in the sleeve and an upper portion above the wide neck; separating the upper portion from the lower portion that thus forms the container.

A solid dosage preparation is provided with a bottle of water. The solid dosage preparation is contained in a safe and sanitary blister package and attached by means of a shrink band to the closure of the bottle. The shrink band provides a tamper-indicating seal for the both the bottle and blister contents. An advantage of the design is that it does not require customization of bottle and closure tooling, and thereby provides a simple and cost-effective means for combining solid and liquid materials in a unitary package. An additional advantage is the robustness of the tamper-indicating system and methodology.

A can lid made of a resin laminate steel sheet for a resin-metal composite container, includes: a top sheet portion; and a curved portion located at an outer periphery of the top sheet portion, in which the resin laminate steel sheet includes a steel sheet, a thermoplastic polyester-based resin layer provided at a first surface of the steel sheet, a modified polypropylene-based resin layer provided at a second surface of the steel sheet, a polypropylene-based resin layer, and an ethylene-propylene copolymer resin layer, a melting point of the ethylene-propylene copolymer resin layer is 135° C. or higher and 150° C. or lower, a melting point of the thermoplastic polyester-based resin layer is higher than a melting point of the polypropylene-based resin layer by 40° C. or more, and a range of a proportion of the ethylene component in the ethylene-propylene copolymer in the ethylene-propylene copolymer resin layer is 1.0 mass % or more and 45.0 mass % or less.

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 resin-coated metal sheet for can lids includes a metal sheet coated with thermoplastic resin films on both surfaces and formed into a can lid. A thermoplastic resin film A based on polybutylene terephthalate (PBT) and polyethylene terephthalate (PET) is heat-fused on a surface of the metal sheet serving as an exterior surface of the can lid, and a thermoplastic resin film B based on polyethylene terephthalate (PET) is heat-fused on a surface of the metal sheet serving as an interior surface of the can lid. A composition ratio (wt %) of PBT/PET in the thermoplastic resin film A on the exterior surface is (PBT/PET)=(40/60) to (80/20), and the thermoplastic resin film B on the interior surface includes 95 mol % or more of PET.

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.

A beverage container for holding pressurized beverages, comprising a cylindrical metal construction, wherein the container side wall includes one or more indentations or indented shapes proximate the container bottom, wherein the indentations or shapes define the shape of a second pouring aperture when ruptured.

Thermoplastic containers comprising an integrated separating component, as well as methods for converting the thermoplastic containers from a three-dimensional configuration into a configuration for enhanced recyclability, are provided. Systems and methods involving the thermoplastic containers are also provided.
