Abstract

Abstract An impact-resistant container having a flexible walled, rupture resistant, fluid impervious body portion in which one or more pleats are formed. The pleats are secured in a folded position by use of an adhesive or by sewing or interweaving the pleated portion with threads or fibers of sufficient strength to hold the pleats in a folded position during normal use of the container as a vehicle fuel tank or for carrying other liquid substances. Upon being subjected to high impact loads, the folded pleats unfold to increase the volume of the container and while unfolding, absorb the energy of impact upon the container to prevent its bursting. This invention is particularly useful in preventing rupture of fuel tanks in airplane or automotive vehicles and greatly reduces the likelihood of fires which result from such ruptured fuel tanks, air droppable containers and any tank or container where high impact loads will be applied. When used as a fuel tank, the container of this invention may be mounted in a vehicle in a breakaway type retainer shell which holds the tank in a folded position during normal use but upon impact, will open up to permit the fuel tank to expand and unfold to absorb the energy of impact.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 83 words
An impact impact-resistant container comprising: a. a flexible walled rupture-resistant, fluid-impervious body portion; b. an integral pleated portion formed in the body portion; c. fibrous means securing pleated portion in a folded position; d. said fibrous securing means being of sufficient strength to retain the pleated portion in the folded position during normal use of the container when filled with its intended contents but adapted to break and permit the pleated portion to unfold when the container is subjected to high impact forces.
Claim 2
Dependent Claim 83 words
An impact impact-resistant container comprising: a. a flexible walled rupture-resistant, fluid-impervious body portion; b. an integral pleated portion formed in the body portion; c. fibrous means securing pleated portion in a folded position; d. said fibrous securing means being of sufficient strength to retain the pleated portion in the folded position during normal use of the container when filled with its intended contents but adapted to break and permit the pleated portion to unfold when the container is subjected to high impact forces.
Claim 3
Dependent Claim 73 words
An impact-resistant container as claimed in Claim 1 wherein the pleats are folded flat against the outside of the walls of the body portion and the entire body portion is enclosed within a retainer shell, said body portion being releasable from said shell upon receiving high impact forces, the energy of such impact forces being absorbed by the unfolding of the pleats in said body portion when it is released from the shell.
Claim 4
Dependent Claim 41 words
An impact-resistant container as claimed in claim 1 wherein the body portion is a fuel tank and breakaway fittings ate provided to attach the tank to the vehicle in which it is used and to attach fuel lines to the tank.
Claim 5
Dependent Claim 20 words
An impact-resistant container as claimed in claim 1 wherein the pleated portion is secured in the folded position by stitches.
Claim 6
Dependent Claim 74 words
An impact-resistant container as claimed in claim 1 wherein the pleated portion is secured in the folded position by a plurality of weft fibers running longitudinally of the pleat, the strength of said fibers being less than the warp fibers with which they are used thereby permitting failure of the weft fibers prior to failure of the weft fibers to permit unfolding of the pleats when the container is subject to high impact forces.
Claim 7
Dependent Claim 16 words
An impact-resistant container as claimed in Claim 5 wherein the warp and weft fibers are interwoven.
Claim 8
Dependent Claim 29 words
An impact-resistant container as claimed in Claim 5 wherein the weft fibers lie in parallel relationship to each other within a loop formed by each of the warp fibers.
Claim 9
Dependent Claim 21 words
An impact-resistant container as claimed in Claim 5 wherein the warp fibers are bonded to the wall of the body portion.
Claim 10
Dependent Claim 28 words
An impact-resistant container as claimed i in Claim 1 wherein part of the pleats of the pleated portion are of high strength and part are of low strength.
