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 () including a spout main body (A) and a closing unit (). The spout main body (A) includes at least a bonded part (), a tubular part (), and a channel (). The closing unit () includes a closing member (), an attaching part (), and a coupling member (). The spout main body (A) is formed with an attached part (). The coupling member () couples a first surface of the closing member () on the attaching part () side and facing the pouch main body part side, and the attaching member (). The closing member () includes a fixed region corresponding to an area of a second surface opposite to the first surface on the attaching part () side thereof in which the coupling member () is coupled, the fixed region being supported by a nozzle () of a packaging container, thereby holding an angle θ formed by the closing member () with an end surface of the bonded part () on the pouch main body part side at less than 90 degrees.

Pouring spout

To provide a pouring spout that allows a nozzle of a packaging container to be accurately inserted into a pouring spout of a refill container. The above-described problem is solved by a pouring spout () provided to a refill container () for pouring contents into a packaging container, and for pouring out the contents stored in the refill container (). The pouring spout () comprises at least a bonded part () bonded to a pouch main body part of the refill container, a tubular part () for pouring out the contents, a flange part () jutting outward at a boundary between the bonded part () and the tubular part (), a channel () for passing the contents from an inside to an outside of the refill container, and a closing member () for opening and closing the channel (). Both end portions of the flange part () separated farthest in a horizontal direction jut slightly outward from an area facing a peripheral wall part of the pouring unit constituting the packaging container.

A pouring spout of a container includes a spout main body, a closing member, and an energizing body. The spout main body includes a tubular pouring part and an attached part. The tubular pouring part includes an inflow port through which contents are flown in from a container main body and an outflow port. The attached part is configured to attach the inflow port to the container main body. The closing member is configured as a separate body from the tubular pouring part and fitted onto an inner circumferential surface of the tubular pouring part to close the inflow port. The energizing body presses the closing member from the container main body toward the inflow port. The closing member is capable of being removed from the inner circumferential surface of the tubular pouring part by an external force applied against the pressing by the energizing body.

Pouring spout of container

A pouring spout includes a spout main body which includes a tubular pouring part and an attached part. The tubular pouring part has a channel which is formed on an inner side of the tubular pouring part. The channel allows contents to pass therethrough. The attached part is positioned on one end side in an extending direction of the tubular pouring part. The attached part is attachable to a container. The tubular pouring part includes a guide that protrudes from an inner wall of the channel toward a center of the channel, and extends in an extending direction of the tubular pouring part.

Coupled structure between pouring spout of refill container and pouring unit of packaging container

A pouring spout of a container includes a spout main body and a closing member. The spout main body includes a tubular pouring part, and an attached part attachable to the container on one end side of the tubular pouring part in an axial direction of the tubular pouring part. The closing member closes the one end side of the tubular pouring part, and is fitted onto an inner circumferential surface of the tubular pouring part on the one end side thereof in such a manner that the closing member is capable of being removed from the inner circumferential surface of the tubular pouring part by an external force applied from other end side opposite to the one end side in the axial direction.
