ABSTRACT:
An article of manufacture comprising an integrally molded plastic cup nestable with indentically formed plastic cups. The mouth of the cup is formed with a threaded portion and a circumferential lip portion therebeneath. The threaded portion may be matingly engaged with a threaded cap, or if desired, the threaded portion may be removed and the lip portion may be matingly engaged with a snap-on cap. Thus a cup with two alternative types of closure means may be manufactured from a single mold and a single inventory can be kept for orders of either type of closure. Air passage means are formed in a surface of the cup wall to permit air to flow therethrough when identical cups are nested thereby preventing difficulty in removing one cup from another due to air pressure differentials inside the nested cups created during storage temperature differentials and during separation of nested cups.
