Abstract: A tamper evident shipping container comprising a generally rectangular box formed from corrugated paper board includes a pair of overlapping top closure panels adhered together in sealed condition by multiple strips of pressure sensitive adhesive disposed therebetween and a pair of overlapping bottom closure panels sealed together in a like manner. Retaining tabs connected to opposite ends of one of the top closure panels and one of the bottom closure panels are adhered to the end walls of the container by pressure sensitive adhesive. The flutes or corrugations which comprise the container material extend transversely of the retaining tabs and the free edges of the top and bottom closure panels so that attempted entry of the container in the regions of seal causes creasing of the container material along the lines of scorrugation. The resulting creases are readily evident from a cursory inspection of the sealed container.
