Abstract
Abstract A tamper evident packaging for contaminatable products. The packaging includes inner and outer gas-tight containers. In one embodiment, the inner container has only one flexible wall and the outer container has only one flexible wall. The inner and outer containers are each pressurized with gas above atmospheric pressure to inflate their flexible walls. In another embodiment of the invention, both walls of each of the inner and outer containers are flexible. The capsules, pill and the like to be protected are located inside the inner container and the inner container is positioned inside the outer container providing a package which is difficult to tamper with and will clearly show evident of tampering both through appearance and characteristic feel to the would be purchaser.
