- the cap 32 is removably attached to the spout 35 to close the spout.
- a cylindrical movable ring 33 which is disposed on the inner periphery of the spout portion 35 and is cut at a lower end substantially obliquely, engages with the cap 32 so as to rotate with the rotation of the cap 32.
- a blade 36 is provided at or near the lower end of the substantially cut oblique shape. .
- the spout 30 has a rotation assisting portion 37 protruding from the outer peripheral surface of the cap 32 and a tampering prevention portion 38 standing upright from the flange portion 34.
- the anti-tampering tool 38 is easily engaged 39 with the cap rotation.
- the spigot 30 shown in Fig. 12 has an inner peripheral surface of the spout 35 so that the movable ring 33 moves up and down as the cap rotates, as shown in Fig. 13.
- a guide groove 40 and a guide protrusion 41 are provided on the outer peripheral surface of the movable ring 33, and the position of the guide groove 40 at the end of rotation is lower than the position of the guide groove 40 at the start of rotation.
- the movable ring 33 moves up and down, and the blade section 36 reliably cuts the openable area 29 of the packaging container. Since the position of the guide groove 40 at the end of rotation is lower than the position of the guide groove at the start of rotation, when the opening operation is completed, as shown in Fig. 4 (c), the unnecessary movable ring 3 3 Hides from the spout and covers the cut end of the openable area.
- a through hole 42 is provided on the side wall of the movable ring 33 for ease of pouring.
- a clean opening in which the laminated film in the openable area does not partially remain in the opening of the container when opening the container or does not give an uncomfortable feeling to the consumer Parts can be formed.
