A package material blank comprises a body panel having a main panel, two second panels arranged adjacent to the main panel and at least one third panel. End closure panels arranged adjacent to the body panel, the end closure panels comprising a top and bottom closure panels arranged adjacent to the main and the at least one third panel, respectively and flap closure panels arranged adjacent to the two second panels. Lines of weakness separate each of the body and end closure panels. A line of weakness is provided on the main panel having a first portion and a second portion, wherein the first portion extends from a first point to a second point and the second portion extend from a third point to the second point.

A liquid container comprises a rigid planar material defining first and second faces interconnected by at least two connecting edges, and each face has an inner surface and an outer surface. The container is characterised in that it is configured to be converted, upon application of substantially opposing forces to two sides of the container, from a planar configuration, in which the inner surface of the first face is substantially adjacent to the inner surface of the second face, to an open configuration, in which the inner surfaces of the first and second faces are spaced apart and which, in combination with the at least two connecting edges, define a volume therebetween for containing liquid.

A packaging container that can be easily disassembled is provided at low cost. The packaging container is formed by a laminate including a base layer being folded into a box shape and each end thereof being overlapped to be sealed with each other, the laminate having a fragile part formed thereon. The laminate further has, for example, a film layer, and includes, as a fragile part, a first scored part formed on a base layer and a second scored part formed on a film in a 2.0-mm-wide band area with the first scored part being a widthwise center.

Described is paper or cardboard packaging produced from mineral oil contaminated, (e.g., recycled) paper, wherein the packaging includes a barrier layer obtainable by applying an aqueous polymer dispersion comprising a copolymer obtainable by emulsion polymerization of C.sub.1-C.sub.4 alkyl (meth)acrylates, acid monomers, e.g., acrylic acid or methacrylic acid, 0-20 wt % of acrylonitrile and 0 to 10 wt % of further monomers in an aqueous medium in the presence of a carbohydrate compound, preferably in the form of a degraded starch, wherein the glass transition temperature of the copolymer is in the range from +10 to +45 C. The barrier layer may be situated on one of the surfaces of the packaging or form one of multiple layers of a multilayered packaging coating or be situated as a coating on one side of an inner bag situated within the packaging.

A carton for holding containers can be converted from a first configuration for storing and shipping the containers therein to a second configuration in which the carton forms an open-top cooler for chilling and serving the containers. A beverage container cooling carton is dimensioned for increased ice surface contact with the outer surfaces of a number of the beverage containers such that heat transfer between the ice and beverage containers occurs efficiently.
