0) and a cap (200), on the lower surface of the top plate (210) of the cap (200),
A two-stage guide inner body comprising an upper stage tube (231) and a lower stage tube (232) having a smaller diameter than the upper stage tube, and forming a plurality of spiral guide slopes (233 and 234) on the respective outer peripheral surfaces. A tube (230) is vertically installed and the spout (1)
00), a plurality of vertical grooves (122) are formed on the inner surface of the discharge cylinder (120).
A plurality of protrusions (131) sliding on the vertical groove are provided on the outer peripheral surface, and a plurality of vertical grooves (132) are formed on the inner surface.
Further, a cover cylinder (130) forming a plurality of guide slopes (133) slidingly in contact with the guide slope (233) of the upper cylinder of the guide inner cylinder is slidably inserted into the inner peripheral surface. A plurality of protrusions (141) sliding on the vertical groove (132) of the cover cylinder are provided on the outer peripheral surface, an opening blade (142) is formed at the lower end, and the lower step of the guide inner cylinder is formed on the inner peripheral surface. A plurality of guide slopes (144) that are in sliding contact with the guide slopes (234) of the cylinder.
Slidably insert the opening cylinder (140) forming
In the middle of removing the cap, the sealing film is broken by the opening blade at the tip of the descending opening cylinder, and when the cap is removed, the tip of the cover cylinder descends from the tip of the opening cylinder. It is a spout plug (10) incorporating an opening blade.

惧がない。[0007] The liquid paper container of the present invention having a stopper with a built-in opening blade protruding from the top is rotated upward by rotating the cap counterclockwise to remove the cap. The cover cylinder housed inside the spout pouring cylinder receives a force in the right rotation direction, with the guide ramp sliding on the inner peripheral surface of the upper cylinder in sliding contact with the guide ramp on the outer peripheral surface of the upper cylinder. Since the projection on the outer peripheral surface of the body is in sliding contact with the vertical groove of the spout discharge cylinder, the cover cylinder moves downward along the vertical groove. Similarly, an opening cylinder housed inside the cover cylinder having a guide slope slidably in contact with the guide slope of the outer peripheral surface of the lower guide inner cylinder of the cap guide inner cylinder,
Although the force in the right rotation direction is received, since the protrusion on the outer peripheral surface of the opening cylinder slides on the vertical groove of the cover cylinder, the opening cylinder moves downward along the vertical groove. For this reason, while removing the cap, as shown in FIG. 2, the opening blade (142) at the lower end of the descending opening cylinder (140) breaks the sealing film (30) sealing the container, and When the cap is opened and the cap is removed, as shown in FIG. 3, the tip of the cover cylinder (130) descends from the opening blade (142) of the tip of the opening cylinder (140) protruding inside the container. Since the cover cylinder covers the opening cylinder, there is no risk of injury to the hands or the like when the used container is disassembled and separated and collected.
