Abstract

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.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 147 words
The method of packing fragile articles utilizing a finite sized container having a bottom wall and a sealed expandable and deflatable tubing of a length greater than the longest inside dimension of the container which comprises disposing a sealed end of the deflated tubing in a first layer over the inside bottom of the container with the remainder of the tubing removed from above the first layer, placing a first group of the fragile articles to be packed on the first layer, disposing another portion of the tubing in a second layer over the fragile articles, placing a second group of fragile articles to be packed on the second layer of tubing, and so forth, until the desired quantity of articles are packed and then inflating the tube with gas to cause the tubing to separate the fragile articles and suspend the articles between the inflated layers.
Claim 2
Independent Claim 147 words
The method of packing fragile articles utilizing a finite sized container having a bottom wall and a sealed expandable and deflatable tubing of a length greater than the longest inside dimension of the container which comprises disposing a sealed end of the deflated tubing in a first layer over the inside bottom of the container with the remainder of the tubing removed from above the first layer, placing a first group of the fragile articles to be packed on the first layer, disposing another portion of the tubing in a second layer over the fragile articles, placing a second group of fragile articles to be packed on the second layer of tubing, and so forth, until the desired quantity of articles are packed and then inflating the tube with gas to cause the tubing to separate the fragile articles and suspend the articles between the inflated layers.
Claim 3
Dependent Claim 23 words
The method of claim 1 wherein the articles are positioned at random out of contact with each other on the layers of tubing.
Claim 4
Dependent Claim 41 words
The method of claim 1 wherein the choice of the inside width of the container and the width of the tube layers is of a close enough size so that upon inflation the tube will engage the sides of the container.
