发明名称 Plastic file sleeve and index cards
摘要 A plastic file sleeve and index card set for organized record retention and use, including a sleeve having two relatively wide end walls, two relatively narrow side walls, open at the top and bottom defining a sleeve cavity therein to receive index file cards as described. The index file cards include a body portion having a width corresponding to that of the sleeve cavity for insertion therein, and include a tabulating strip portion across the top of the card which is wider than the sleeve. The tabulating strip portion of the cards includes shoulder portions which project outwardly from each opposite end beyond the corresponding respective side edges of the body portion of the cards. The outwardly projecting shoulder portions of the cards rest against the top edge of the sleeve, thereby supporting the tabulating strip portion above the sleeve for visual examination without having to reach in the sleeve and withdraw cards for examination. The tabulating strip portion of each card includes a rectangular panel across its width and a raised tab portion projecting upwardly from the upper edge of the rectangular panel. The raised tab portion is located at a different point on each card in the set and arranged so a portion of each tab is visible when the cards are placed in the sleeve. The side walls of the sleeve include longitudinal ribs formed on the inward facing surfaces thereof.
