ABSTRACT:
A pouring spout for a container has a tubular body to be mounted on a container wall, the inner surface of the tubular body having a guiding recess therein extending parallel to the axis of the tubular body, the recess having a greater width at the portion thereof toward one end of the tubular body and a shoulder at an end corresponding to another end of the tubular body; a tubular blade movably mounted within the tubular body and having a longitudinal projection on the outer surface thereof and an outward projection at the end of the longitudinal projection corresponding to the one end of the tubular body, the longitudinal projection being slidably engaged in the recess for guiding movement of the tubular blade into the tubular body in a direction from the one end toward the other end, the shoulder having a notch portion in an inner peripheral edge having a cross-sectional shape different from the cross-sectional shape of the longitudinal projection for blocking movement of the tubular blade in the direction at a set position within the tubular body by engagement of the longitudinal projection with the shoulder at the position of the notch portion, and the shoulder being deformable for permitting the longitudinal projection to fit into the notch and permit movement of the tubular blade in the direction past the set position until the outward projection engages the shoulder; and a cap mounted over the tubular body.
