  • Plugging-type resin cap
    Patent number: 10894637
    Abstract: Provided is a plugging-type resin cap which can sufficiently seal a container and in which, upon uncapping of the container, a restraining band loosens after the pressure in the container is released without the application of an excessive force. A plugging-type resin cap (100) includes a restraining band (130), a tab (140), and engagement projections (151). The restraining band (130) has an arcuate restraining portion (131), stoppers (132), and an upwardly projecting portion (133). The stoppers (132) are formed to extend radially outward from the circumferential both ends of the restraining portion (131). The engagement projections (151) are disposed over an outer side surface of a skirt wall (120) in the vicinity of the circumferential both ends of a tab (140). The stoppers (132) and the engagement projections (151) are formed to be fittable with each other.
