The method including providing a sheet of material in the form of a strip, first folding the sheet of material onto itself to form a first package face and a second package face that oppose each other, a first end portion and a second end portion of the sheet of material extending from the first package face, sealing the sheet of material along opposed longitudinal edges of the sheet of material, fixing the first end portion and the second end portion to each other to form a sealing flap, first defining an opening cut in the sealing flap, the opening cut being defined by both the first end portion and the second end portion, and connecting the sealing flap to the first package face to form the assembled package, the opening cut not being visible or directly accessible on the assembled package.

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 drawn aluminum can shell has a peripheral crown which is double-seamed with an end portion of an aluminum can body to provide a can end having a generally flat center panel connected by an inclined curved or straight panel wall to an inner wall of an annular U-shaped countersink. The countersink has an outer wall which connects with a lower wall portion of a chuck wall, and the chuck wall has an upper wall portion which connects with an inner wall of the crown. The chuck wall also has an intermediate wall portion forming a break, and the inner bottom width of the countersink is less than the radial width of the panel wall.

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 crimping unit (1) having a first plate (10); a first lever (50) equipped with a winding wheel (54), a second lever (60) equipped with a crushing wheel (64), a winding actuator connected to the first lever (50), and a crushing actuator connected to the second lever (60). The winding actuator and the crushing actuator are governed by an electronic control unit (7) to vary the distance between the winding wheel (54) and/or the crushing wheel (65) of the first axis according to the angular position of the first plate (10) around the first axis.

The disclosed systems and methods relate to improved cases for securely storing and shipping products. A case can include a back panel, 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 case is foldable into a closed configuration such that a lower holder panel, a lower front panel, and a bottom panel form a lower box configured to hold the bottom of the first product, and an upper holder panel, an upper front panel, and a top panel form an upper box configured to hold the top of the first product.

A can end (10) for a two-piece beverage container (1) has a public side (32) opposite a product side (34). A cured coating (76) is on the product side (34) of the can end (10) and forms a substantially continuous thin layer thereon. A circumferential curl (12) is centered about a longitudinal axis (50). A circumferential chuckwall (14) extends downwardly from the curl (12). A circumferential U-shaped countersink (16) is located downwardly from the chuckwall (14). The countersink (16) has an annular bead defining a lowermost vertical extent of the can end (10). A center panel (18) is located radially inwardly from the countersink (16) and is centered about the longitudinal axis (50). The center panel (18) has a means for providing an opening in the can end (10). A circumferential second coating (92) forms an annular layer on the product side (34) of the circumferential curl (12) and the cured coating (76). The second coating (92) provides a layer on one or more fractures in the cured coating (76).
