ABSTRACT:
A box-like container receives a deflated sealed expandable tube which is disposed with one sealed end as a first layer of the tube over the inside bottom wall of the container. Fragile articles are then laid on the upper side of this first layer in a random fashion and spaced apart. A second layer of the tubing is then disposed across the fragile articles and another group of fragile articles is positioned on the second layer of tubing. The tubing is then disposed across this second group and so forth until the container is filled to the desired extent. The tube is then inflated with a gas to expand the tubing between the fragile articles and will suspend the articles between the inflated layers. A closure valve is disposed in a convenient location for the inflating and deflating of the tube.
