ABSTRACT:
A tamper-resistant package for articles such as pharmaceuticals and medicine which are themselves first enclosed within a first closed and sealed container. The first container is then enclosed within a second container, there being a void between the two containers. The second container includes a lid which is secured over its opening. Positioned between the lid and the opening of the second container is a permanently adhered thin sheet of elastic material or membrane which is impermeable to gas or liquid. This membrane is permanently adhered to the opening of the second container after the sealed first container and a portion of solid chemical material possessing the physical property of sublimation is placed into the void. In conjunction with the expansion into gas of the solid sublimation material at atmospheric pressure and normal ambient temperature subsequent to the permanent adhesion of the lid to the membrane and over the opening of the second container, the membrane stretches and expands outwardly from an aperture in the lid to produce visible and touchable positive evidence that the package has not been tampered with. The membrane is permanently destroyed when the lid is removed or when the membrane is punctured, cut or otherwise ruptured in any manner. This physical indicia remains in tact for at least the shelf life of the article, unless tampering occurs. A transparent protective cover releasably connected over the lid is also provided.
