面に接合して成る容器用キヤツプ。 As described in detail in the main text and shown in the drawings, a cap body 2 that fits airtightly into the mouth of a container has a spout 3 whose upper surface is formed into a valve seat 17 at approximately the center thereof, and a peripheral wall 4 and an extension thereof on the periphery of the upper surface. A receiving tongue portion 5 is provided, and a fulcrum post 7 whose upper end is bent into a hook shape and forms an engaging protrusion 6 is provided at the rear thereof, and the upper surface of the cap body 2 is engaged with the engaging protrusion 6. Engagement protrusion hole 1
8 and rotates to open and close using the lid as a fulcrum.
The opening/closing lid 8 has a valve lid 9 facing the valve seat 17 at the center thereof, and a flexible membrane 10 at the periphery. A protrusion 11 that engages with the opening/closing lid 8 is formed in its vicinity, and the rear end of the opening/closing lid 8 is extended into a thin film to form a movable hinge 14, which is connected to a leaf spring 12. Reference numeral 12 designates a container cap whose lower end is expanded into a thin film to form a fixed hinge 13, which is then joined to the side surface of the cap body 2.
