ABSTRACT:
A hexahedral drinking fluids carton comprising an upwardly tapered outflow opening extending from a bottom portion of a side wall of the carton and communicating with an access opening at a bottom portion of a diamond-shaped bendable guide part. At the top portion of the guide part, an outflow mouth can be folded flat against a top wall of the carton and interposed between a cover, applied to the carton, and the top wall so as to seal the carton. A removable protective covering portion of the cover is positioned above the outflow mouth so that the outflow mouth can be exposed when the protective covering portion is removed from the cover.
