ABSTRACT:
A tamper-evident container and a method for making the same. The container includes at least one open end with integral flaps adjacent the open end. A thermoplastic material is applied to one flap with the other flap folded over onto the one flap. The flaps are thus sealed together with a thermoplastic material. A temperature-sensitive indicator is applied to the closed end so that the indicator visually indicates whether an excessive amount of heat has been applied to the seal of thermoplastic material.
