Reclosable package or bag with audible reclosure

摘要

The present disclosure relates a reclosure or zipper for a reclosable package or container, such as a plastic bag, wherein opening or closing the zipper causes an audible sound and a tactile feel. The reclosure or zipper is manufactured by an apparatus which includes a cutting wheel which is opposed to a pressure wheel. The cutting wheel includes cutting teeth spaced about its periphery. Interlocked zipper material is engaged between the cutting wheel and the pressure wheel to form indentations in the interlocked zipper, thereby resulting in audible and tactile feedback when the zipper is operated.
