ABSTRACT:
A molded, back-off resistant closure for use with an associated container having a neck portion and at least one outwardly projecting ratchet formation includes a generally circular top wall portion and a skirt portion depending from the top wall portion. The skirt includes an inner wall and an outer wall and defines a lower wall portion. The skirt terminates in an edge and includes a thread formation formed in the inner wall for matingly engaging the neck portion of the container. The closure includes a plurality of lugs recessed from the edge and extending radially inwardly from the lower wall and longitudinally along the lower wall portion a distance so as to not touch the edge. The lugs extend outwardly and downwardly such that at least one of the lugs can engage the at least one outwardly projecting ratchet formation on the container neck portion when the container and closure are engaged with one another.
