Abstract: In a carton employing a turned-under lip along at least a portion of its periphery, an easily openable, non-resealable tab is provided for securing the carton lid to the body of a carton. The tab provides an easy open feature, secures the lid to the body of the carton, provides visual assurance that the carton has not been pilfered and eliminates the cost, nuisance and disposal problems normally associated with prior art overwrap materials and tear-out zippers. The tab requires a very low opening force which is highly reproducible. In addition, the tab is unaffected by minor carton damage. The tab is formed as an integral portion of the carton lid, is easily produced on standard packaging equipment, and, in a particularly preferred embodiment, requires no additional packaging material other than that required to form the carton lid.
