Abstract

A pack container for liquids is described, comprising an upright folded carton containing an inside bag of plastic material. In its upper region the pack container is slanted on one or two sides to roughly approximate the appearance of a washing concentrate bottle. Optionally the pack container can be provided with a filling and pouring sleeve with a screw cap closure arranged in its head end or it can be opened at one of its slanted sides, whereby zig-zag shaped folded sections of the main surface areas (1, 4) of the folded carton can be uprighted to thus form a pouring opening in which a corner tail of the inside bag is accessible for cutting off.
