ABSTRACT:
Packing members which are formed from expanded plastic foam sheet, such as polystrene, wherein the sheet is resilient. The sheet is provided with a backing which may be formed of bendable paper. A typical packing member will be formed by dividing the sheet into two legs by a longitudinal groove which is V-shaped in cross section and which does not extend into the backing. The surfaces of the foam sheet defining the V-groove are coated with an adhesive which will bond the legs together in annular relation at a later date so that the packing member may be shipped in its flat state. Because of the compression of the sheet material, it may be readily bent to form corners as opposed to cracking with the result that a leg of the packing member may be provided with a V-notch to divide that leg into two portions. The V-notch will be closed when the other leg is bent at right angles.
