Abstract
A tamper-proof package for articles, such as medicine, is disclosed. The package comprises a first container into which the articles to be protected are placed. A second container made of a substantially gas impermeable material encloses the first container. The space between the first and second containers is filled with a pressurized gas such as air and the second container is sealed. Two elastic layers are tightly stretched about the second container and sealed.

10. A method for packaging an article comprising the steps of:
-
completely enclosing a first container containing the article with a flexible gas impermeable second container, a space existing between the first and second containers; pressurizing the space between the first and second containers with a gas; removing the source of pressurized gas and simultaneously sealing said second container so that a quantity of the pressurized gas is maintained therein; and surrounding said second container with a first elastic layer tightly stretched about said second container. - View Dependent Claims (11, 12)

13. A method for tamper-proofing a container for an article comprising the steps of:
-
completely enclosing the container containing the article with a flexible gas impermeable second container, a space existing between said containers; pressurizing the space between said containers with a gas so as to inflate said second container; and sealing said second container so that a quantity of the pressurized gas is maintained therein, said second container thereby being in a normally inflated state, said second container deflating upon puncture to thereby give a visual indication of tampering. - View Dependent Claims (14)
