ABSTRACT:
A container (1) for liquid products fashioned from at least one blank of multi-layer paper material comprises an essentially parallelepiped body (2) with four side walls (4, 5, 6, 7), and a top section (9) presenting four angled faces (4a,5a,6a,7a) that converge toward a tubular element (17) providing a spout (15) from which to pour the liquid contents. The tubular element (17) also presents four tags (24) designed to interact with the top section (9); the tags function as anchors insertable between and weldable together with the corresponding edges (11) of the blank to form joined areas (12) serving as both closure and reinforcing elements in the finished container (1).
