Theinner end margins 29 of the two panels 26 at either end of'the -bIank are mutually convergent, and the width of'the" panels 26'is increased somewhat at 30;-to extend outwardly beyond the lines of the two side wall panel "hinge;- creases23: 'Iheouter sideinargins 3111 of panels 26 parallel "thei respective lines of creaseslf.

The ends ofthe hingedly fconnected partition sections 17 are-extendedlbngitudinallfbeyond' the" line of the creases 27 which hinge divider end wall panels 26 to floor panels 18.

In assembling the divider in the outer casing 11, the medial partition crease 17 is manually pre-broken downwardly and the various divider wall and floor panels 18, 22, 26 are also pre-broken in the opposite direction about their respective creasesto one another and to the partition section 17. The panels 17 of partition 16 are then compressed sufliciently to increase clearance of the divider relative to the side walls of the casing, whereupon the divider is dropped or pushed into the latter. Floor panels 18 are engaged with the bottom 32 of casing 11 and partition 16 is released, whereupon its inherent resilience causes the divider unit to expand outwardly into the operative position illustrated in Figs. 1, 2 and 3.

In this position of the divider its partition 16 and its various panels are very strongly and effectively braced by interengagement with one another. For example, end wall panels 26 have edge engagement at their respective inner, convergent edges 29 with the side surfaces of the partition panels 17, in substantially spaced relation in wardly of the longitudinally projected ends of the partition as illustrated in Fig. 3. Their outer edges 31 are directly buttressed by easing side walls 15. At the same time, the inner surfaces of divider end panels 26 are edge-engaged by the outwardly divergent end edges of the side wall panel 22 (Fig. 2). Thus any tendency of the partition 16 to sway or shift sidewardly is resisted by panels 26 and any tendency of these end wall panels 26 to shift endwise out of bracing position is efiectively contained by the panels 22 and end walls 13. This is the case even should side wall panels 22 shift inwardly somewhat, though the contents of the container will ordinarily prevent this. The floor panels 18 cannot slide outwardly. A very strong and rigid divider construction which correspondingly strengthens and rigidifies the container as a whole, is thus provided.

The respective divider end and side wall panels 26, 22, in their inclined relationship to the end and side walls 13, 15 of casing 10, afford ventilating spaces along the sides and ends of the divider, and the spaces defined by side panels 22 are open to the ventilating holes 14. The entire interior of the casing 10 is well ventilated to eliminate spoilage of produce in transit, and uniformity of distribu tion of ventilation is furthered by the small ventilating openings 21 respective junctures of the partition, floor and wall panels 17, 18, 22 and 26 of the divider. It may be noted that spoilage of fruit and produce most frequently occurs adjacent the walls of any shipping container, particularly at the bottom zone thereof. Hence the provisions described are of particular value in correcting this draw back.

It will also be noted that ventilation is further improved by the fact that the respective pairs of flap-like members which constitute the bottom 32 of outer container 10 do not quite meet at the center of the latter. This affords a bottom air opening 33 (Figs. 2 and 3) for the supply and discharge of air.
