Abstract
Abstract 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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
398 words
A sleeve file case and card set, comprising a tubular member, said tubular member including a central cavity therethrough which opens to both opposite ends of said tubular member, a plurality of cards slidably positioned in said cavity being slidably removable therefrom, each of said cards including a body portion having a transverse dimension corresponding to that of said central cavity for insertion of said body portion in said cavity, each of said cards being in substantially full frictional engagement with at least one other of said cards, wherein said tubular member is rectangular in cross-section having the same cross-sectional dimension and configuration for one end of said tubular member to the other, a first relatively wide end wall, a second relatively wide end wall spaced apart from said first end wall to define said central cavity between said end walls, a top edge of said end walls bordering the opening of said cavity at one end thereof, a bottom edge of said end walls bordering the opening of said cavity at the opposite end thereof, and a plurality of longitudinal ribs formed on the inner surfaces of said end walls projecting into said cavity to contact an adjacent one of said cards and space said cards from said inner surfaces of said end walls, said plurality of ribs on each end wall being spaced apart a first distance to reduce friction between said cards and said end walls when said cards are tightly packed in said cavity, said first distance being greater than the cross-sectional dimension of one of said ribs, each of said ribs extending from one end of said tubular member to the other and each of said ribs having the same cross-sectional configuration and dimension continuously from one end of said tubular member to the other wherein said plurality of cards includes a first card, said first card includes a main body portion having a width less than the width of said cavity of said tubular member, a top border portion having a width greater than the width of said cavity, said means to retain said cards in position in said cavity including an overhang portion of said top border portion which exceeds the width of said cavity, and extends laterally beyond said cavity and across at least a portion of the top edge of said side walls when said card is inserted therein.
Claim 2
Dependent Claim
398 words
A sleeve file case and card set, comprising a tubular member, said tubular member including a central cavity therethrough which opens to both opposite ends of said tubular member, a plurality of cards slidably positioned in said cavity being slidably removable therefrom, each of said cards including a body portion having a transverse dimension corresponding to that of said central cavity for insertion of said body portion in said cavity, each of said cards being in substantially full frictional engagement with at least one other of said cards, wherein said tubular member is rectangular in cross-section having the same cross-sectional dimension and configuration for one end of said tubular member to the other, a first relatively wide end wall, a second relatively wide end wall spaced apart from said first end wall to define said central cavity between said end walls, a top edge of said end walls bordering the opening of said cavity at one end thereof, a bottom edge of said end walls bordering the opening of said cavity at the opposite end thereof, and a plurality of longitudinal ribs formed on the inner surfaces of said end walls projecting into said cavity to contact an adjacent one of said cards and space said cards from said inner surfaces of said end walls, said plurality of ribs on each end wall being spaced apart a first distance to reduce friction between said cards and said end walls when said cards are tightly packed in said cavity, said first distance being greater than the cross-sectional dimension of one of said ribs, each of said ribs extending from one end of said tubular member to the other and each of said ribs having the same cross-sectional configuration and dimension continuously from one end of said tubular member to the other wherein said plurality of cards includes a first card, said first card includes a main body portion having a width less than the width of said cavity of said tubular member, a top border portion having a width greater than the width of said cavity, said means to retain said cards in position in said cavity including an overhang portion of said top border portion which exceeds the width of said cavity, and extends laterally beyond said cavity and across at least a portion of the top edge of said side walls when said card is inserted therein.
Claim 3
Dependent Claim
76 words
A sleeve file case and card set as set forth in claim 1, wherein said plurality of longitudinal ribs includes a first plurality of said ribs on said first end wall, a second plurality of said ribs on said second end wall, the number of ribs in each of said pluralities being equal, the ribs on said first end wall being in facing relationship respectively to corresponding ones of said ribs on said second end wall.
Claim 4
Dependent Claim
201 words
A sleeve file case and card set as set forth in claim 2, including a pair of side walls respectively joining said first and second end walls along the opposite edges thereof, said side walls and said end walls having said longitudinal ribs comprising the entire peripheral boundary of said cavity, the surfaces of said end walls lying continuously in respective ones of spaced apart first planes extending through said cavity, the surfaces of said longitudinal ribs lying continously in respective ones of a plurality of second planes extending through said cavity, the surfaces of said side walls lying continuously in respective ones of spaced apart third planes extending through said cavity, said first, second and third planes extending through said cavity being continuously parallel to the longitudinal axis of said cavity from one end thereof to the other, said tubular member being of extrudable material, whereby said tubular member of said sleeve file case may be completely formed by drawing a block of said extrudable material through an extrusion die having a core wall of cross-sectional configuration and dimension corresponding to the cross-sectional configuration and dimension of said surfaces of said end walls, said longitudinal ribs and said side walls.
