A can comprises a metal can body and a metal lid. The can body has an edge defining a top opening into the body, and an inwardly directed bead (22) extending around the body adjacent to the top opening. The bead defines an upwardly facing sealing surface (25) and an inwardly facing surface (26). The lid has a centre panel (30), a wall (32) surrounding the centre panel, and an outwardly directed curl (34) at the top of the wall. The curl defines a peripherally extending channel (35) having an opening therein, and sealing compound (36) is located within the channel and projects through the opening. The can body and the lid are dimensioned to allow the lid to be press-fitted into the can body, so that an outwardly facing surface of the wall opposes the inwardly facing sealing surface of the bead, whilst the sealing compound is in sealing engagement with the upwardly facing sealing surface of the bead.

The can container includes a can barrel and a can bottom, the can bottom provided with, in a center thereof, a dome part concaved toward the inside of the can container along the can axis direction, and an annular convex part projecting toward the outside of the can container to shape an annular support part in an outer periphery of the dome part, wherein an inner peripheral surface extending from the support part of the annular convex part to an outer peripheral edge part of the dome part includes a recessed part where the outer peripheral edge part of the dome part is positioned in a direction of being farther away from the can axis than an innermost part of the inner peripheral surface.

A method for manufacturing a beverage use can, which is provided with a cylindrical part with one end portion and the other end portion, a bottom part positioned at the one end portion of the cylindrical part, the bottom part having an outer circumferential surface with an outer diameter gradually increasing with a move toward the other end portion of the cylindrical part, includes a protection layer forming process applying ink to the outer circumferential surface of the bottom part to form a protection layer on the outer circumferential surface.

An urging member configured to constitute a base for a can, comprising a peripheral edge, at which the urging member is to be connected to a side wall of a can at one end thereof to form a semi-fabricated can; an urgeable area surrounding having a normal state in which at least a central part of the area is outwardly convexly curved; and a pattern of elements formed in the urging member and located between the peripheral edge and a central axis thereof. The elements comprise at least one strengthening rib extending along the peripheral edge and protruding in the outward direction of the urging member, and urgeability-providing elements located between the central axis and the at least one strengthening rib. The urgeability-providing elements are angularly spaced from each other about the central axis, being radially spaced from the strengthening rib and being configured to provide the urgeable area with the ability to be repeatably elastically displaceable in an inward direction, upon the manual application of an urging force to the urgeable area by at least one finger of a user, thereby changing the state of the urgeable area from a normal state in which the central portion of the area is disposed at a first location with respect to the reference plane, to a deformed state in which the central portion is disposed at a second location spaced from the reference plane to a greater distance than in the normal state; and in the outward direction upon release of the urging force, thereby changing the state of the urgeable area from the deformed state to the normal state.

A coating composition includes: (a) 60 to 90 percent by weight of an active hydrogen-containing polyester having a number average molecular weight of at least 23,000, an acid value below 5 and a hydroxyl value below 10, (b) 0.1 to 10 percent by weight of a polyanhydride, and (c) 5 to 30 percent by weight of a curing agent reactive with the active hydrogens associated with (a) and (b), the percentages being based on weight of resin solids of the coating composition, where the reaction product of the coating composition forms a single coating without including a thermoplastic polymer. The coating composition is useful in coating food and beverage containers, particularly 2-piece cans formed by drawing and redrawing (DRD).

An environmentally friendly can for containing a product includes a sealed container that contains the product and includes a polyester resin and a release mechanism to open the container and access the product. The polyester resin may be a furan resin selected from poly (ethylene 2, 5-furan dicarboxylate) (PEF), poly (butylene 2, 5-furan dicarboxylate) (PBF), poly (trim ethylene furan dicarboxylate) (PTF), poly (propylene 2, 5-furandicarboxylate) (PPF), and poly (neopentyl 2, 5-furandicarboxylate) (PNF); and/or a biodegradable polyester resin such as polyglycolic acid (PGA). The can may further include a generally cylindrical shell molded to have a sealed bottom and a straight wall that includes the resin; and a cap to seal the shell, the cap having the release mechanism and a rim that includes the resin; wherein the rim of the cap is bonded to the wall of the shell to releasably seal the product inside the can.

A first aspect of the present invention provides a can container including: a can body of a cylindrical shape, and at least a surface coating layer, in which the surface coating layer is formed on at least a part of an outer peripheral surface of the can body, the surface coating layer has a resin component, and surface free energy of a surface of the surface coating layer is 30 mJ/m.sup.2 or more and 50 mJ/m.sup.2 or less at a temperature of 25° C.

A container assembly includes a container, a closure and a one-piece tamper-evident label. The container has a neck portion defining an opening and a body portion. The body portion includes at least one sidewall and a bottom opposite of the neck portion. The closure fits to the neck portion of the container for closing the opening. The closure includes a top wall portion and an annular skirt portion depending from the top wall portion. The one-piece tamper-evident label is permanently attached to the container and the closure. The label includes at least one line of weakness extending across thereof. The label covers a majority of the at least one sidewall and substantially extends around the circumferences of the container and the closure. The label is configured to be separated into at least a first label portion and a second label portion via the at least one line of weakness.

Provided is an object to be printed which can improve the quality of a printed image in inkjet printing on the object to be printed, regardless of the resolution of an inkjet image. In a method for producing an object to be printed having an area to be printed on a surface thereof, a surface of the area to be printed is adjusted so that the area to be printed has a surface energy E (mN/m) of 30 or more and 50 or less. The object to be printed is selected from a can and a film for containers.

A bottom forming system for a metal container includes a domer assembly that forms a double dome in a bottom of the metal container during a bottom forming process. The domer assembly includes a first domer and a second domer that is movable relative to the first domer. A method of forming a bottom of a metal container includes forming a first dome profile in the bottom of the metal container using the first domer and the second domer of a domer assembly. The method includes forming a second dome profile in the bottom of the metal container by moving the second domer relative to the first domer.
