This capped spout is provided with a spout (1) and a cap (30) engaged with the spout (1). The spout (1) has a cylindrical body (3) and a weld part (4). An internal space of the cylindrical body (2) is configured as a pouring passage (2) for pouring out a content liquid of a pouch-shaped package, and a cap (30) is mounted on the cylindrical body (2) so as to block an opening at an exit end of the pouring passage (2). The weld part (4) is formed on the outside of a cylindrical body (3), and is a portion welded to a mouth part of the package. The capped spout furthermore has a thin film part (11) formed on the inside of the cylindrical body (2) so as to block an opening at an entrance end of the pouring passage (2). The thin film part (11) has a first surface facing the internal space of the cylindrical body (2) closed by the cap (30) and the thin film part (11), and a circumferential groove (12) having the center of the thin film part (11) at the center thereof is formed in the first surface. The circumferential groove (12) is configured from an arc-shaped first groove (12a) and an arc-shaped second groove (12b) which is longer than the first groove (12a). Linear third grooves (13a, 13b) in the first surface extend outward in the radial direction of the cylindrical body (2) from both ends of the second groove (12b), the first groove (12a) has an unbreakable configuration, and the second groove (12b) and the third grooves (13a, 13b) have a breakable configuration. An arc-shaped fourth groove (14) is furthermore formed in the first surface in a portion positioned on the outside in the radial direction relative to the first groove (12a) and between the pair of third grooves (13a, 13b), and the fourth groove (14) has an unbreakable configuration. |
