Abstract: A light-activated, sound-providing device (122) is slideably received in a cavity (64) formed in an insert (52) of a size and shape for receipt in the hollow volume of a container (10) with a friction fit. The insert (52) has a volume generally corresponding to the volume of consumer food product which would normally be received in the container (10). The provisions (50) for retaining the sound-providing device (122) includes a paperboard medallion (60) secured to the insert (52) including text and graphics (62). In a preferred form, the sound-providing device (122) is not activated while in the interior of the closed container (10) but when the container (10) is opened by removal of its closure layer (13), the sound-providing device (122) is activated providing a sound for prize announcement, attention getting, or a similar function.
