Abstract: A hermetic multi-barrier tamperproof package for encasing articles such as pharmaceutical products and the like, is disclosed. The package comprises: a first container typically being made of a substantially impervious plastic material into which the articles to be protected are placed prior to hermetically sealing the container so as to enclose the articles, and so as to further enclose normal atmosphere air within the container. A second container typically being made of a substantially impervious plastic material completely encloses the first container. The first and second containers are simultaneously separated from and connected to one another by attaching means comprising one or a number of discs having appertures in their centers, so as to allow a hermetic cavity defined between the first and second containers to extend continuously therebetween.
