The function of the envelope 2 is to cover the center hole 3 and read slot openings 4 in a diskette rigid cartridge 5 so that debris is not introduced into the cartridge 5 interior to contaminate the enclosed magnetic media. For function, appearance, and low cost, the envelope must have a thin wall cross section and no molding draft. Blow molding provides these features and is capable of low cost/high volume production. The envelope is removed for use of the cartridge and replaced after use for storage protection with the label 10 exposed. The central depression 8, secures the envelope to the cartridge by projecting into center hole 3.
