WIPO Patent Application WO/2023/168692
Kind Code:
A1
Abstract:
The invention relates to a planar composite (100) comprising a. a carrier layer (1404), b. a barrier layer (1407), and c. an inner polymer layer (1408); wherein the planar composite (100) includes at least a first plurality of grooves (101) arranged and configured such that at least a part of a container wall (1101) of a closed container (1100) is obtainable by folding along the grooves and joining portions; wherein the closed container (1100) includes a standing base (1103) and a head portion (1102); wherein the head portion (1102) includes at least 3 head side surfaces (209) inclined to each other in a longitudinal direction (201) such that the closed container (1100) tapers at least in sections in the head portion (1102); wherein a perimeter of each of the head side surfaces (209) is respectively formed by a plurality of side edges; wherein each of the plurality of side edges includes a pair of steep edges (1104); wherein each pair of steep edges (1104) is formed along a pair of grooves (210); wherein the grooves of each of the pairs of grooves (210) are at an angle (211) in the range from 40 to 60° to one other. The invention further relates to processes (1500, 1600, 1700) of manufacture and corresponding process products; a container precursor (400) and a closed container (1100), each comprising the planar composite (100) or a blank (200) thereof; a further closed container (1100); and a use of the planar composite (100) or the container precursor (400).
