Abstract
A spout (1, 401, 601) having a plastic spout body which comprises an attachment portion (10, 410, 610) having a vertical first plane of symmetry (M1) with a vertical first sealing wall (11, 411, 611) and an opposed vertical second sealing wall (12, 412, 612), and with a transverse wall (20), which is integrally connected to an upper edge of the first sealing wall and to an upper edge of the second sealing wall, wherein the first sealing wall and the second sealing wall each depend from said transverse wall and each have a bottom edge (114, 115, 541, 515, 714, 715) remote from the upper edge. Each sealing wall is, seen in a bottom view of the attachment portion, composed of a first rectilinear portion (111, 121, 511, 521, 711, 721), a central curved portion (113, 123, 513, 523, 713, 723), and a second rectilinear portion (112, 122, 512, 522, 712, 722). The spout body has a tubular neck (30) having a bore (31) that adjoins an opening (21) in the transverse wall. The attachment portion further comprises curved stabilizing ribs (15, 16, 151, 161, 152, 162) extending between associated connection points to the opposed rectilinear portions of the sealing walls.
