The cross walls are further characterized in each instance by the provision of two.

24. The general form of the blank so folded is that of the letter W. The folds 22 occupy sets of means either or both of which coact with the blank to secure the cross walls lowermost positions, the folds 23 are ad acent the upper edge of the carton, and the folds 24 are adapted to occupy substantially 1h a l lelatloh hheewlth In the a center postion' when the blank is closed h p h Shown herem, P Wan over to provide covers for the carton. The h w 1 Q m vertlcauy bends 21 are disposed between the center from lts PP g? A flanhg entrance d b tt f ld 20 d 22, as h Th for the slot is provlded by slantmg backat sections of the blank between the fold 20 and 2' n g fl-a from the pp slot side a lug 53 pro ects partly across the entrance to the slot. When a cross wall is bends 21 provide a vertically extending double wall 0. Between the bends 21 and 22 v inserted through the slots 35 into final position, its lug 53, which is bent laterally durare oblique sections d, between the folds 22 ing this operation, will straighten out into the proximate slot 36 to overlie the vertical folds 23 and 24 are cover sections f. Joined to each cover section at the fold 24 is a flap and 23 are other sections 6, and between the g. In addition the blank is adapted to'be double wall 0.

slots are openings 36 arranged in a row along the lines 31 which defines between' rous product, may be as'follows: The carton is first doubled The lugs 53 and slots 35 constitute one set of means for interlocking the blank and cross walls. I provide also another set of interlocking means which serve additionally and independently to sustain the inneroblique sections of the blank intermediately in W- formation, as shown in Figs. 1. and 2. Such an interlock desirably includes each cross wall wherein are provided additional slots or incisions--65 in line with the sections d of the blank. Interrupting the continuity of the slots 35 of the blank are obstructing lugs 66 adapted to be received within the slots 65 of the cross walls when the latter are assembled in position within the blank. By this means the cross walls are held in place independently of the interlock afforded by the co-operatin vlu s and slots 53 and 36, respectively, an ad itionally, the carton bottom is maintained centrally throughout its length with the inner sections of the blank sustained intermediately in the W formation shown.

The operation of assembling the cross walls B in the carton blank A may proceed upon itself along the fold line 20 so as to bring the two sets of slots 35 into register. The cross walls are'then inserted into position within these slots the lengthof which exceeds the vertical dimension of the cross walls, and the latter are then shifted lengthwise of the blank slots so as to bring the double walled section 0 down toward the lower end of the cross wall slot 51. During thismovement the double'walled section '0 of the blank may be required to bend while moving past the obstructing lugs 53. In the final position, the parallel-edges of the slots 51 afford support toopposite sides of the double walled section 0 such thatit is held against tilting. The lugs 53 which project into the recesses 36 prevent a reverse movement of the blank relative to the cross walls, and the projection of the lugs 66 into the slots cause the inner sections of the blank to be hooked up obliquely into the position desired for thesustaining of eggs or other commodities.

With the walls assembled into the blank in this manner, the parts are interlocked securely against displacement. For convenience in packing and shipping, the walls may be turned flat against the blank and in this knock-down condition the carton occupies but very little space. It may be set up for use by bending the blank along the folds 22.

which has the effect of bringing up the sections 6 and h until the latter are hooked into the notches ll. With the parts so related, the lugs 46 act to retain the'outer sections of the blank in a set-up condition with its upper sections f and 9 opened out to permit insertion of eggs or other commodities into the cells defined by the blank sections 03- and e and the intervening cross wiills. As these cells are filled, the obliquely disposed sections 01 and 6 will tend to bow out, in so far as permitted by the interlocking lugs and slots 66 and 65, respectively, in conformity with the contour of the eggs or other commodities so set. in place. The

upper" portions of the blank consisting of the sections f and 9 may thereafter be folded over the top of the carton, the "sections f meeting substantially along the center fold 20 so as to permit insertion of the two flaps g vertically into the slots 51 along one side of the double wall 0.

.is afforded to the carton bottom such that the latter is adequately sustained at an elevated point regardless of the load which may be introduced into the carton. The

various longitudinal bends or folds in theblank provide, in effect, a pluralityof hingedly connected strips forming side and bottom walls of a trough of which there are two, arranged side by side.

I claim:

1. An egg holder or filler in which is comprised a blank bent in the form of a letter W with slotted oblique bottom sect-ions meeting at an elevated point centrally of the holder, the blank also providing front and rear sides and a cover,a plurality of cross walls collapsibly supported within the blank and extended through the slotted bottom sections thereof, and coacting means on the cross walls and oblique central bottom sections for sustaining said oblique bottom sections at a point intermediate per and lower edges.

2. An egg holder or filler having a slotted blank with longitudinal bends such that it may provide a cover, front and '"rear sides and a bottom in which is comprised a pair of upwardly inclined transversely slotted sections meeting centrally for the length of the holder; cross walls extended vertically from the cover through the slotted bottom sections, and an interlock between the cross walls and obliquecentral bottom sect-ions for snstainingsaid inclined bottom sections at a point intermediately of their upper and lower edges.

3. An egg holder or filler having a slotted blank with longitudinal bends such that it y of their upmay provide a cover, front and rear sides and a bottom inwhich is comprised a pair of upwardly inclined transversely slotted sections meeting centrally for thelength of the holder, cross walls extended vertically from the cover through the slotted bottom sections, and an interlock between the cross walls and inclined central bottom sections for sustaining said inclined bottom sections at a point intermediately of their upper and lower edges, said interlock comprising means interrupting the continuity of the slots in the inclined bottom sections together with a complementary incision in the cross Walls for receiving such 1neans.

4. An-egg holder or filler blank with longitudinal bends such that it may provide a cover, front and rear sides /and a bottomin which is comprised a pair of upwardly inclined transversely slotted sections meeting centrally for the length of the holder, cross walls extended vertically from the cover through the slotted bottom sections, and coacting means on the cross walls and inclined central bottom sections of the blank for sustaining said inclined bottom sections at a point intermediately of their' upper and lower edges, said means comprising lugs on the one extended into lncisions in the other located between the upper and lower edges of-the inclined bottom sections and oppositely with respect to the longitudinal center of the holder.

5. In a collapsible egg holder, foldable tro'ugh members arranged side by side and having oppositely inclined slotted bottom sections-meeting in a ridge centrally of the holder, a plurality of cross walls collapsible with the foldable trough members and ex- 40 tended vertically through theinclined slotted bottom" sections, said cross walls and trough members being so formed as to interlock at the ridge and along the inclined central bottom sections below theridge. I
