Abstract

Abstract A floppy disk container comprises a plate having an adhesive tape or agent applied to a rear face thereof. Three edges of a flexible plastic film of an approximately square shape are fastened to the plate, and the remaining edge of the film is free from attachment to the plate and positioned at a mid portion of the plate in order to obtain an upwardly opening insertion opening of the floppy disk container. Thus, a bag-like floppy disk container is obtained. A pair of stoppers are formed to protrude from an upper portion of the front face of the plate at positions just above the top edge of the floppy disk when the floppy disk is in the container, so as to abut the top edge of the floppy disk and prevent the floppy disk from falling out of the container. In addition, a transverse elongated ridge in parallel with the insertion opening is formed on the front face of the plate between the insertion opening and the stoppers, in order to leave a gap between the top edge of the floppy disk and the plate 3.
