Abstract:
1. A pouring plug fitted to a packaging container, the packaging container possessing a vertically extending wall intersecting a top part having a tilted surface that is tilted at least forward on a front side of the top part of the packaging container, the tilted surface being provided with an area for pre-laminated hole sealed by film, the pouring plug comprising a frame body, a cap and a cylindrically-shaped movable ring, the frame body forming a pouring spout, the frame body comprising a flange connected with said tilted surface at a circumference of said area for pre-laminated hole and a cylindrically-shaped spout portion integrally moulded with the flange and extending from the flange approximately at an angle from the flange so as to be substantially parallel with the vertically extending wall, and wherein said cap is fitted removably to said pouring spout portion so as to plug said pouring spout, and said movable ring being disposed at an inner circumference of said pouring spout, said cylindrically-shaped movable ring engaging said cap so the movable ring and said cap rotate together as a unit, the movable ring possessing a lower end portion cut at an angle to form a cutting part which cuts the film when the cap and the movable ring are rotated to provide access to an interior of the packaging container, wherein the packaging container also includes a substantially flat surface adjacent to the tilted surface on a rear side of the top part and the height of the cap fitted on to the pouring spout portion is lower than that of the flat surface of the top part of the container, the angle of the lower end portion of the movable ring being substantially parallel to the area for pre-laminated hole sealed by the film in an initial position of the movable ring before the movable ring is rotated toward a cutting position to cut the film, and being not parallel to the area for pre-laminated hole sealed by the film after the movable ring is rotated toward the cutting position and cuts the film.
