1. A rupturable container comprising:

  • a first layer of flexible sheet material;

    a second layer of flexible sheet material;

    first means bonding said layers together over first regions of said layers to form laminated sheet material;

    second means preventing preselected confronting regions of said layers from being bonded together as securely as said first regions; and

    third means joining zones of the second layer of said laminated sheet material together to form a closed container, said first and second layers being folded back on each other and being creased at said preselected confronting regions of said layers to form a mechanically weakened region of the container at said preselected confronting regions whereby when the container is struck said weakened region ruptures as a result of the action in said second means and the mechanical weakening of said preselected confronting regions to expose said substance.
