the container of this invention may be seen in its fully assembled and operational form in fig1 - 7 . container body 20 is a rectangular prismoidal shape , which in one preferred form is substantially cubical . container body 20 has an upper horizontal wall 22 , a lower horizontal wall 23 , a rear vertical wall 24 , two vertical sidewalls 25 and a vertical open front 26 . cover 21 is removably attachable to container body 20 to function as a cover for open front 26 and may be swung along path 45 to leave front 26 open or closed . inside of container body 20 are two sets of grooves for holding floppy discs in a vertical position standing on edge . a first plurality of grooves 27 lies on lower wall 23 with grooves 27 running lengthwise parallel to each other and to vertical sidewalls 25 . grooves 27 have an open side 29 facing upward , and they extend from open front 26 to adjacent rear wall 24 . in a similar but opposing fashion , there is a second plurality of grooves 28 lying along upper wall 22 . grooves 28 are parallel to each other and to sidewalls 25 , and they extend from open front 26 to adjacent rear wall 24 . open sides 30 of grooves 28 face downwardly toward grooves 27 and are respectively aligned vertically with grooves 27 . it will be appreciated that with such alignment a floppy disc may be supported on edge in two such respective grooves . on the outside of sidewalls 25 adjacent open front 26 there is a shaft seat strip 31 . each strip 31 has two grooves 32 and 35 which serve to hold cover 21 in each of its two operating positions . upper groove 32 is positioned adjacent open front 26 and upper wall 22 . as illustrated in fig1 and 2 , a preferred embodiment has upper groove with an open end 33 with a vertical entrance at upper wall 22 and a closed end 34 positioned downwardly and rearwardly from open end 33 . according to this embodiment , lower groove 35 is adjacent open front 26 and lower wall 23 . open end 36 of groove 35 is positioned at open front 26 and closed end 37 is rearward of open end 36 . cover 21 has a front or outer face 38 , a back or inner face 39 , and two side arms 40 which extend rearwardly over the outside of sidewalls 25 substantially at right angles from faces 38 and 39 . facing each other on the inside of arms 40 ( not seen in fig1 and 2 but visible in fig5 - 7 ) are two short stub shafts 41 aligned with each other . shafts 41 are adapted to slide into grooves 32 and 35 and be seated in closed ends 34 and 37 . on the outside face 38 there is an area 42 which has been prepared , as by smoothing or lightly roughening , to receive an adhesive coated identification label to describe the contents . as shown in fig1 cover 21 may be engaged with upper grooves 32 and be pivotable to any open position or closed against container body 20 . in fig2 there is shown a second position for cover 21 in which it is engaged by lower groove 35 and pivoted rearwardly and under container 20 to lie against lower wall 23 and form a support base for container body 20 with open front 26 tilted slightly upward with respect to rear wall 24 so that the floppy discs in grooves 27 and 28 will not tend to roll out of container body 20 and may be easily inserted therein . in fig3 - 4 it may be seen that weight reducing voids 53 and 54 are employed and interspersed with grooves 27 and 28 , respectively . in fig5 - 7 there are shown tabs 43 and 44 projecting outwardly from inner surface 39 of cover 21 . there tabs are shaped and positioned to function as snap - closure structures to maintain cover closed against container body 20 in each of the positions shown in fig1 and 2 . tab 43 is positioned to fit into recess 51 to hold cover 21 closed against open front 26 . tab 44 is positioned to engage the corner formed by the intersection of rear wall 24 and lower wall 23 when cover 21 is in the position shown in fig2 . cover 21 is attachable to container body 20 by means of stub shafts 41 sliding into a pair of upper grooves 32 or a pair of lower grooves 35 . it may be seen that shaft seat strip 31 is a thin piece of material approximately the same thickness as the length of stub shafts 41 . grooves 32 and 35 pass through walls 25 . in this manner stub shafts may be slid into groove openings 33 or 36 and pushed into seating at closed ends 34 and 37 , respectively , and will be snugly seated there and yet easily pivoted . it is preferred that container body 20 and cover 21 be injection molded of a suitable plastic material , e . g ., polyolefin , polyester , polyacetal , polycarbonate , polyamide , polyvinyl , acrylic , and the various blends and copolymers associated therewith . suitable tapering and draft must be employed to allow the molded object to be easily removed from the mold . such has been shown in fig3 and 4 where open front 26 is slightly larger in area than rear wall 24 with the connecting corners tapered or inclined therebetween . in this embodiment it is preferred that grooves 27 and the associated structure be integrally molded with the structure of walls 22 , 23 , 24 , and 25 , while grooves 28 and their associated structure be molded as a separate unit 47 and assembled later to container body 20 . this arrangement also makes it more convenient to employ weight reducing voids 53 and 54 so as to reduce the cost of the final structure . by separately molding several pieces of the container body 20 and assembling the pieces into a single structure , the molding process can be simplified . container body 20 can be preferably manufactured by separately molding the five - walled container with grooves 27 along the bottom wall 23 as one unit , two shaft seat strips 31 as mirror images of each other , and one upper groove structure 47 as one unit . these four items are then adhesively joined together to produce a container body 20 . cover 21 is also separately molded as a unit and then is attached to container body 20 as needed . in fig8 and 9 there is shown one of shaft seat strips 31 , in this case the one shown in fig1 . a second strip 31 is needed for the opposite side of container body 20 and would be a mirror image of the one shown . each strip is molded with grooves 32 and 35 as shown and , preferably , with a lip 55 which forms a convenient indexing guide for assembling strips 31 to sidewalls 25 . in fig1 - 13 there is shown upper groove structure 47 with a front wall 48 and a rear wall 49 , grooves 28 and weight reducing voids 54 . for ease and accuracy in assembling structure 47 to container body 20 , the latter is molded with a groove 46 extending from open front 26 to rear wall 24 ( see fig1 - 2 ). structure 47 is molded with flanges 50 to slide into grooves 46 with rear wall 49 abutting into rear wall 24 of container body 20 . adhesive is employed between rear wall 24 and rear wall 49 to maintain structure 47 in place . thus , with three pieces molded to the base container structure , the final container body is easily produced . it is , of course , to be understood that other routes to the manufacture of container body 20 may be followed without departing from the essence of this invention . in fig1 and 15 there are shown the ways in which cover 21 is clamped to contained body 20 . in fig1 , cover 21 is in position as the supporting base under lower wall 23 as shown in fig2 . tab 44 snap fits around corner 52 which is the intersection of lower wall 23 and rear wall 24 . in fig1 , tab 43 is shown inserted into recess 51 in the middle of the front edge of lower wall 23 . in this position cover 21 fits snugly over open front 26 closing the entire opening . container 20 and cover 21 form an excellent storage for floppy discs without need of dust covers , since cover 21 will perform that function for all discs in the container . the number of slots 27 and 28 may obviously be increased or decreased for various embodiments of this invention . eight pairs of slots are shown here to house eight floppy discs . with more than eight slots the container 20 and cover 21 will become a wider rectangular shape , but will function equally well in all other regards . eight appears to be a convenient number since it provides a structure that is substantially cubical . spacing between adjacent slots 27 or 28 is maintained at that which is convenient for inserting a finger or thumb to grasp a disc . as mentioned previously , when cover 21 is attached as a supporting base as shown in fig2 it is desirable to have it structured to raise lower wall 23 to a higher elevation at open front 26 than at rear wall 24 . this provides an inclination to grooves 27 and 28 tapering downwardly toward rear wall 24 . by this means , discs will not inadvertently roll out the front but will remain in place . while the invention has been described with respect to cerain specific embodiments , it will be appreciated that many modifications and changes may be made by those skilled in the art without departing from the spirit of the invention . it is intended , therefore , by the appended claims to cover all such modifications and changes as fall within the true spirit and scope of the invention .
