ABSTRACT OF THE DISCLOSURE 5-gallon plastic molded bottles of at least two manufacturers have neck profiles which differ slightly but have a diameter where the variation in profile is at a minimum. The cap of this invention fits at least two profiles. In each profile there is an outward-convex bead below the top lip. The interior of the skirt of the cap curves concave approximately co-extensive with such bead curvature and has plural circumferential internal annular ridges which engage the bead at about its maximum diameter. Below the ridges is an internal annular tension ring having a diameter when unstressed less than the diameter of the top neck bead at its circle of contact which engages below the maximum bead diameter and hence tends to pull the ridges down into tighter engagement with the profiles of either manufacturers' neck finish. Below the tension ring the skirt is formed with a horizontal tear line which extends about 265° of the circumference of the skirt. A second score line curves down to the bottom edge of the skirt. A tear tab projects down adjacent the terminus of the curved score line. To properly seat the cap on the neck and to reduce resistance to the capping operation, narrow vertical internal ribs radially spaced apart are formed on the inner skirt slightly below the horizontal score line.
