A capped spout of the present invention has a spout (1) and a cap (30) that engages with the spout. Spout (1) has a cylindrical body (3) and a welding part (4). Cylindrical body (2) has an interior that serves as a discharge passage (2) for discharging liquid content in a bag-shaped package, wherein the cap (30) is attached to the cylindrical body (2) in order to close an opening of an outlet end of the discharge passage. The welding part (4) is formed outside the cylindrical body (3) and is welded to an opening of the package. The capped spout of the present invention further has a thin film part (11) that is formed inside the cylindrical body (2) in order to close an opening of an inlet end of the discharge passage. Thin film part (11) has a first surface that faces an interior of the cylindrical body, the interior being closed by the cap (30) and the thin film part (11). A circular groove (12) that is concentric with the thin film part is formed on the first surface. The circular groove (12) is formed of an arc-shaped first groove (12a) and an arc-shaped second groove (12b) that is longer than the first groove (12a). Third linear grooves (13a, 13b) extend on the first surface outwardly from each of both ends of the second groove (12b) in a radial direction of the cylindrical body (2). The first groove (12a) is unbreakable and the second (12b) and third grooves (13a, 13b) are breakable. An arc-shaped fourth groove (14) is further formed on the first surface, wherein the fourth groove is located radially outward of the first groove (12a) between a pair of the third grooves (13a, 13b). The fourth groove (14) is unbreakable.

1. A capped spout comprising a spout and a cap that engages with the spout, the spout comprising: a cylindrical body having an interior that serves as a discharge passage for discharging liquid content in a bag-shaped package, wherein the cap is attached to the cylindrical body in order to close an opening of an outlet end of the discharge passage; anda welding part that is formed outside the cylindrical body and that is welded to an opening of the package, whereinfurther comprising a thin film part that is formed inside the cylindrical body in order to close an opening of an inlet end of the discharge passage;the thin film part has a circular groove that is concentric with the thin film part, the circular groove is formed on a first surface of the thin film part, the first surface faces an interior of the cylindrical body, the interior being closed by the cap and the thin film part;the circular groove is formed of an arc-shaped first groove and an arc-shaped second groove that is longer than the first groove, third linear grooves extend on the first surface outwardly from each of both ends of the second groove in a radial direction of the cylindrical body, and the first groove is unbreakable and the second and third grooves are breakable; and,an arc-shaped fourth groove is further formed on the first surface, the fourth groove is located radially outward of the first groove between a pair of the third grooves, the fourth groove being unbreakablewherein, except in an area of the fourth groove, the first surface has a plurality of arc-shaped fifth grooves formed along a circle, the circle including the fourth groove and the fifth grooves being unbreakable; andthe first surface further has at least one sixth groove that extend from the respective fifth grooves to the second groove in a radial direction of the cylindrical body, wherein the sixth groove are breakable,wherein the thin film is separated into a first part and a plurality of second parts, wherein the first part includes a central portion inside the circular groove and an outer circumferential part that faces the fourth groove, and the first part can be folded along the first groove, and wherein the second parts are outer circumferential parts that face the fifth grooves, and the second parts are circumferentially divided by the third and sixth grooves and can be folded along the fifth groove. 2. The capped spout according to claim 1, wherein when a second surface of the thin film part that is opposite to the first surface is pushed toward the interior of the discharge passage, the second groove and the third grooves are broken, a central part of the thin film part that is defined by the second groove is then turned around the first groove that serves as a hinge so that the central part is pushed into the discharge passage, the opening of the inlet end of the discharge passage is then opened, the hinge is then prevented from being folded back by the fourth groove so that the opening of the inlet end of the discharge passage is kept open. 3. The capped spout according to claim 1, wherein a center angle that is formed by both ends of the first groove with regard to a center of the thin film part is 45 degree to 120 degree. 4. The capped spout according to claim 1, wherein the cylindrical body has an annular rib formed on an outer surface thereof, the annular rib is in close contact with an inner surface of the cap in order to prevent liquid from entering the cap when the cap is attached to the cylindrical body so that the opening of the outlet end of the discharge passage is closed. 5. The capped spout according to claim 4, wherein an outer surface of the cylindrical body and an inner surface of the cap have thread parts that engage with each other, respectively, the thread parts are located in a closed space formed by the cap and the annular rib when the cap is attached to the cylindrical body so that the opening of the outlet end of the discharge passage is closed.
