Tamper evident bag

Abstract

A security bag includes a pair of overlapping wall panels joined at their bottom and side edges to define an opening at the top of the wall panels for carrying money and other items. One of the wall panels includes a receipt strip extending from the top of the panel and connected to the wall panel along a perforation line. The receipt strip and one of the wall panels each carry an identical identification number. The receipt strip is removable from the security bag by severing along the perforation line. A closure flap is provided for closing the opening of the bag when the receipt strip is removed. The closure flap includes a strip of tape having an adhesive on one surface that is adhered at a lower attachment portion of the tape to one wall panel. A release liner covers the adhesive on an upper sealing portion of the tape and is readily removable to expose the adhesive for adhering the closure flap to the other wall panel to close the bag opening. The lower edge of the release liner is disposed below the perforation line so that the strip of tape does not adhere to the receipt strip, thereby preventing its removal from the security bag. The strip of tape includes a security pattern that is imperceptible when the bag is properly closed, but becomes visible on the wall panel and the closure flap when the flap is pulled from the wall panel. The security panel remains visible, even when the flap has been resealed over the opening to give a positive visible indication of tampering with the security bag.
