Patent ID: 11845591

Abstract:
To provide a pouring spout in which an open state of the closing member is maintained while contents are being transferred. The above-described problem is solved by a pouring spout (10) including a spout main body (10A) and a closing unit (20). The spout main body (10A) includes at least a bonded part (15), a tubular part (11), and a channel (18). The closing unit (20) includes a closing member (21), an attaching part (24), and a coupling member (23). The spout main body (10A) is formed with an attached part (40). The coupling member (23) couples a first surface of the closing member (21) on the attaching part (24) side and facing the pouch main body part side, and the attaching member (24). The closing member (21) includes a fixed region corresponding to an area of a second surface opposite to the first surface on the attaching part (24) side thereof in which the coupling member (23) is coupled, the fixed region being supported by a nozzle (58) of a packaging container, thereby holding an angle θ formed by the closing member (21) with an end surface of the bonded part (15) on the pouch main body part side at less than 90 degrees.
