Claim 1

A disc record package consisting of a substantially U-shaped, plastic enclosure, and a pair of plastic, T-cross sectioned side rails; said U-shaped enclosure comprising a pair of spaced panel portions interconnected by an end portion along one side of said panel portions; each of said side rails having an edge wall portion and an intermediate flange portion extending substantially perpendicularly from said edge wall portion to define a pair of channels; each of said side rails having an integral raised step portion in each channel thereof; said perpendicular flange portions being inserted between the respective side edges of said panel portions such that said edge wall portions of said side rails are substantially flush with said side edges of said panel portions; wherein plasticizing energy is applied to said integral step portions, while said panel portions are securely held against said flange portions, to fuse said side rails to said enclosure to form said package; the improvement comprising making the inside surfaces of said edge wall portion of each of said side rails extend away from said perpendicularly-disposed, intermediate flange portion to provide room for excess molten plastic from the respective one of said integral step portions in said channels.
