Title: Container cushions and containers incorporating such cushions
IPC: B65D81/05
Filed: 1972-04-21
Abstract: 1379652 Cushioning material for packages DEFENCE SECRETARY OF STATE FOR & EPS (RESEARCH & DEVELOPMENT) Ltd 19 July 1973 [21 April 1972] 18646/72 Heading B8C [Also in Division F2] A container cushion formed from a resilient sheet of material shaped in a manner to reduce the effective stiffness of the material and further being arranged so that, on exertion of compressive forces above a particular value, the degree of stiffness exhibited by the material suddenly reduces and the material buckles, has at least one corrugated element, the, or each, corrugated element having, as viewed in transverse section, a generally curvilinear first face and a truncated triangulated second face, side walls of the second face of each corrugated element each being inclined to the general plane of the sheet at an angle of between 55 and 75 degrees, and the arrangement being such that, any compressed and deformed portion will return substantially to the original form thereof on removal of the impact load. The sheet material is formed from a material having a low " cushion factor " the latter being directly proportional to the thickness of the sheet of material and the " optimum static stress " of the latter. The " optimum static stress " is evaluated by dropping weights at a fixed height on to the specimen material and measuring the peak de-acceleration of the weight for each value of static stress. The loading at which peak de-acceleration has its lowest value is designated the " optimum static stress ". Cushioning of packages which vary widely in size, weight and fragility necessitate the use of a number of materials covering a range of " optimum static stress " from less than 0À1 lb./sq. inch to well over 1À0 lb./sq. inch. Expanded polyethylene and polyurethane foam, which are light, durable, and not costly, are preferred materials respectively for high and low optimum stress conditions. In a corrugated sheet 1 of expanded polyethylene or chipfoam, the inner surface of each corrugation is inclined at an angle of 65 degrees. The sheet may be secured to a base of rigid sheet material, a multi-layer arrangement of this kind being shown in Fig. 6. The inner side walls of the corrugations are preferably inclined at an angle of within 5 degrees of 65 degrees.
