ABSTRACT:
The neck of a plastic container for motor oil or similar thin fluids is formed wiht plural, discrete, smooth external conical surfaces and further formed with shoulders below each such surface. The cap for such neck has an interior generally complementary to the exterior of the neck. Internal cap beads engage under the shoulders of the neck. At least the lowermost cap shoulder is preferably interrupted. Above each bead is an internal circumferential rib which seals against the corresponding smooth conical surface of the neck. The lower portion of the cap including the lowermost bead may be torn away, permitting the upper part of the cap, which functions as a reclosure cap, to be pried off the neck. For such purpose, the cap wall is made thin below the second locking bead and a downward-slanted scoreline extends from the thin area to the bottom edge of the cap. A tear tab extends below the bottom edge of the cap adjacent the terminals of the score line. Standoffs space the tab from the neck for ease in gripping the tab.
