ABSTRACT:
An anti-creeping cap to prevent the self unscrewing of a cap from a container used for edible products. The cap has an internal screw thread and multiple spaced engagement ribs extending from a secondary depending annular flange that correspondingly engaged to a number of registering projections extending from the neck finish of the container. Moderate torsional rotation input force is required to disengage the registering projections from grooves formed between the ribs which is accomplished by the flexation of the flange for cap removal.
