Abstract
A blister pack, particularly adaptable for use with batteries, is designed to incorporate a space for holding an electronic article surveillance sensor. The package consists of a blister of clear thermoformed plastic which has a thermoformed recess which holds the displayed product. The blister is then heat-sealed to a paperboard backing card which forms the backing of the blister pack. In order to incorporate the sensor the cavity of the blister is made deeper so the product is spaced away from the cardboard blister. This space is filled by a thin thermoformed thermoplastic tray. The tray has a surface which engages and supports the product, such as batteries, and a second surface which engages the card and a third surface which is spaced from the batteries towards the card which supports the electronic article surveillance sensor out of engagement with the batteries.
