A coated container includes: a container having a surface; and a coating applied to at least part of the surface to form a coated surface. Leaching of at least one of one or more types of ions or one or more types of compounds is determined by performing an alkaline treatment on at least part of the coated surface to obtain an alkaline treated surface and performing an acidic treatment on at least part of the alkaline treated surface to obtain an acidic treated surface. The leaching of the at least one of one or more types of ions or one or more types of compounds from the coated surface is 5.00 mg/l or less.

An aluminum alloy foil having superior formability is provided. An aluminum alloy foil, including 0.8 to 2.0 mass % of Fe, 0.05 to 0.2 mass % of Si, and 0.0025 to 0.5 mass % of Cu, with the rest consisting of Al and unavoidable impurities, wherein the aluminum alloy foil has an average crystal grain size of 20 μm or less, and a number of intermetallic compounds existing in the aluminum alloy foil, the intermetallic compounds having a circle equivalent diameter of 1.0 to 5.0 μm, is 1.0×10.sup.4 grains/mm.sup.2 or more, is provided.

A container for alcohol, e.g., a wine bottle, formed of a polycarbonate wall sandwiched between exterior and interior coatings, at least one of which may be an epoxy of 4,4′-isopropylidenedicyclohexanol and 1-chloro-2,3,-epoxypropane, crosslinked with 3-aminopropyltriethoxysilane. The polycarbonate wall may be an extrusion blow molded monolithic form at least 1.5 mm thick, and either or both of the exterior coating and the interior coating may have a thickness between 1 nm and 100 μm, inclusive.

A method for the distribution and dispensing of beverages utilizes a one-way system including a disposable and freestanding container. The container is blow-molded in one piece from a preform of plastics. The system also includes a tube to be inserted in the container and a closure cap. The container can be filled, distributed to an end user and connected to standard beverage dispensing structure. After use, the empty container is collapsed and discarded.

A preform for an integrally blow-moulded bag-in-container uses an inner layer and an outer layer, wherein the preform forms a two-layer container upon blow-moulding, and wherein the obtained inner layer of the container releases from the thus obtained outer layer upon introduction of a gas at a point of interface between the two layers. At least one of the inner and outer layers includes at least one additive allowing both inner and outer layers to reach their respective blow-moulding temperatures substantially simultaneously.
