    Abstract: A spout assembly includes a spout and a cap. The cap includes an inner ring having an outer peripheral surface provided with a first region with a first outer diameter and a second region with a second outer diameter. The spout includes a side wall having an inner peripheral surface provided with a first region having a first inner diameter and a second region having a second inner diameter. When the cap is threadably engaged with the spout, the first region of the inner ring is in close contact with the first region of the side wall of the spout throughout the circumference, and the second region of the inner ring is in close contact with the second region of the side wall of the spout throughout the circumference.

    Abstract: Provided are a spout stopper that prevents a decrease in sealing performance to a cap without deterioration of liquid-shutting-off performance of a stopper body, and a packaging container using the spout stopper. The spout stopper includes: a stopper body including a cylindrical side wall; and a cap to be mounted from an upper end side that is one end of the side wall. A projection is formed at an upper end edge of the side wall so as to project outward from the side wall, and a top surface at an upper end of the side wall is in surface contact with a predetermined contact surface inside a cap over an entire circumference thereof in a state where the cap is mounted on the side wall.

    Abstract: In a container having a lid member coupled to a container body by a hinge, the lid member has a top panel, and an inner ring formed on the top panel, the inner ring being fitted to an inner peripheral surface of a sidewall of the container body in a closed state to seal the container body. The inner ring has an outer peripheral surface on which an outer peripheral surface projection is formed along a circumferential direction, and the container body has an inner peripheral surface on which an inner peripheral surface projection is formed along the circumferential direction, in the vicinity of an end portion of the sidewall. When closing the lid member, the outer peripheral surface projection contacts and slides over the inner peripheral surface projection to cause the lid member to be locked to the container body, with the inner ring sealing the container body.
