Abstract (en)

[origin: WO2009094215A2] Spouts, particularly for flexible fluid reservoirs, include a generally cylindrical neck portion and a pair of opposed, generally triangular portions extending laterally there from characterized as spout-film or spout weld interface(s). Invention embodiments include use of a spout material having a melting temperature that is closely matched to at least a portion of film-spout or film weld interface(s), which are part of the flexible fluid reservoir film; use of spout weld interface surface characteristics characterized as substantially flat and/or smooth, and/or characterized as negative relief surface features such as holes or depressions; use of at least one stress delocalizing feature characterized as flexible appendages, preferably at the convergence of opposing sides of a spout (the apex of the triangular portions) or at neck portions that form a portion of the spout weld interfaces, which depend beyond the spout weld interface and into the reservoir; and/or use of spout edges and/or portions of the spout weld interfaces that are flexible in comparison to the neck portion of the spout.
