A sealable container is formed by a cylindrical member and a sealing cap for mating with the cylindrical member. A flexible tether is integrally connected to the sealing cap and the cylindrical member. The tether has a slide ring with at least one frangible bridge connecting the ring to the cylindrical member. Alternatively, the slide ring of the tether has at least one frangible bridge connecting the ring to the sealing cap. The sealing cap can have a frangibly connected lower skirt which fractures when the sealing cap is opened. Alternatively, the slide ring connected to the sealing cap by at least one frangible bridge can have a frangibly connected lower skirt which fractures when the sealing cap is opened. The cylindrical member may be a container or a fitment with a flange to attach to a container.
