Abstract
A novel snap on pull off tamper indicating cap and neck configuration for containers, the cap having a top with an annular depending wall on its peripheral edge and seven circumferentially spaced continuous spiral thread configurations on the inner surface of the annular depending wall. A removable tear skirt with continuous ratchet teeth on its inner surface depends from the outer peripheral edge of an outturned flange on said annular wall. An annular rib on said ratchet teeth, the tear skirt is joined to the flange with only the points of the ratchet teeth, a pull tab on the tear skirt with frangible lines enabling removing of the tab and tear skirt from the cap. Ratchet teeth on the container have a continuous longitudinally extending notch within for interlocking registration with the annular rib on the ratchet teeth of the tear skirt.
