FILLERQANDVI FLAT FOR CONTAINERS Kitchener K. Newsom, San Francisco, Calif. Application August 3 1936', Serial No. 93,993

' a Claims. .(01. 217-265) I This invention relates to ,a packing. for eggs and fragile articles. f

, An object of this invention is to provide fillers and flats for cases or boxesin whicheggs or other fragile articles can be packed in larger quantities in.a given space with complete protection against breakage.

Another object of the invention is to provide a shipping box and particularly an egg carrier which is highly useful and simple in construction, convenience of arrangement, lightness and comparative inexpense of manufacture are further objects which have been borne in mind in the production and development of the invention.

I am aware that some changes may be made in I the general arrangements and combinations of the several devices and parts, as well as in the details of the construction thereof without departing from the scope of thepresent invention as set forth in the following specification, and as defined in the following claims; hence I do not limit my invention to the exact arrangements and combinations of the said device and parts as described in the said specification, nor do I confine myself to the exact details of the construction of the said parts as illustrated in the accompanying drawing.

The invention is clearly illustrated in the accompanying drawing, wherein:

Figure 1 is a fragmental view of the flats and fillers assembled in an egg box.

Figure 2 isa fragmental plan view of a flat or packing sheet. a

Figure 3 is a sectional view of the flat, or packing sheet, the section being taken on the line 3-3 of Figure 2. I

' Figure4 is a fragmental side View of a strip of cellular spacer or filler, and

' 'Figure 5 is a fragmental side view of another strip of the filler.

In the herein illustration I show an embodiment of my invention in connection with packing eggs' Eggs are packed in a-case or box 6 in staggered layers, each egg 1 in anindividual cell. This is accomplished by a stack of alternate flats 8 and fillers 9. Each flat 8 is made of a molded or pressed sheet, whichvi's slightly fiexible and resilient. There are a plurality of parallel rows of aligned concavo-convex depressions provided on each sheet in parallelism with an edge of the sheet. The concave sides of said depressions are on the same side-of the flat 8 toform seats ll for the ends of the eggs. The convex sides of said depressions protrude beyond the plane of the other side of the flat 8. The seats II are equally spaced from each other a a suitable distance to be in alignment with the centers or axes of the cells of the adjacent filler. Anotherset of simi' lar depressions is provided on the other side of each flat 8. The concave seats I2 of this second 5 set face oppositely to the seats II andare staggered and offset midway between the rows of seats H of the first set in both directions. The convex sides of the depressions of the secondset protrude beyond the first side of the flat 8 and 10 are equidistant from all the adjacent seats II. The flat 8 is rectangular and its marginal edges are spaced from the outer rows of seats at a distance equal to the parallel distance between the centers of the adjacent opposedseats I I and I2.

Around the rim of each seat I I or I2 is provided an annular rib l3 which latter is also preferably of concavo-convex cross section, bute'ach rib protrudes oppositely from the seat which it surrounds. In cross section the concave side'of each seat is in continuation of theconvex side of the rib l3 at the rimof vthe seat. The rib I3 is of larger diameter than the portion of the article or eg adjacent to it. Each egg'has its opposite ends supported in said seats l l and i2 and due to the resilient reinforcing action of the rib 13 the egg can better withstand axial loads exerted thereon. In other words each flat has parallel rows of holders and each holder is made of a concavo-convex bottom portion forming a seat H or l2. Said bottom portion is solid and continuous so as to be contacted by the respective tip of the egg. The convex side of such seat projects beyond a face or side of the flat, and the rim of each seat projects beyond theother, opposite face or side of the flat and Fthenit is turned upon itself back to the plane of the sheet thus forming a concavo-convex rib B. which resiliently connects the rim of the bottomiportion to the sheet. The diameter of the rib I3 is sufiiciently large to permit the end of the egg to rest directly on the solid bottom portion.

Each filler is made up of two sets of spaced parallel stripsarranged between two adjacent flats 8. One set of parallel strips intersects all the strips of the other set, so as to inclose a plurality of cells for theeggs.v The strip l4 shown in Figure 4 is similar to all the strips parallel with it. The lines of intersection of each strip l4 with the strips of the other set is-formed by ver- '50 tically aligned recesses I 6 and I1 respectively at the top and bottom of the strip l4, and by a slot l8 which starts at the recess l6 and extends to a limited distance transversely to the strip M. A

' hole I8 is provided outside of and in alignment 5;;

with the inner end of each slot I8. The spacing between the slots l8 determines the width of each cell of the filler along said strips M.

The strip 2|, shown in Figure 5, is similar to all the strips parallel with it, which intersect the first strips |4. Each strip 2| is also provided with vertically aligned recesses 22 and 23 at the top and bottom of each line of intersection. From each bottom recess 23 extends upwardly and at an angle to the vertical an open slot 24 for engagement with the respective slots l8 of the other strips I4. A prong or tooth 26 is formed on the top side of each slot 24 so spaced from the longitudinal edges of the strip 2| that the prong 26 is aligned with the hole l8 of the intersecting strip |4 when the filler is properly assembled.

In assembling the filler the strips 2| can be slightly bent to allow the complete interlocking of the slots 24 and I8 and then when released the prong 26 engages the adjacent hole l9 and positively prevents accidental release of said interlocking slots. The same positive interlocking is established at all lines of intersection of the strips l4 and 2| .of the filler. The spacing of the filler strips l4 and 2| is such that the recesses are aligned with the convex sides of the depressions in the flats at each end.

It is to be noted that the layers of eggs vertically overlap on account of the staggered packing and because the seats II and I2 are depressed beyond the respective planes of the flats 8.

The fillers at two adjacent sides thereof have the ends 21 extended to a greater degree than the other opposite remaining ends 25! thereof, thus the same fillers may be used on both sides of the flats 8, by a horizontal turn of an upper filler, relatively to the adjacent lower filler. In other words a filler is so placed on a flat 8 that the bottom recesses l6 and 23 at all interlocking points are substantially in registry with center lines of the convex projections of said fiat and the cells of the filler are centered above the concave seats N. Then another flat 8 is placed on top of the filler with concave seats |2 centered in said cells. By turning the next filler so that the longer ends of the strips thereof are opposite difierent walls of the box than those of the lower filler, the cells of this upper filler will be centered over the seats ii on the upper side of the last flat 8. The tiers of filler cells and eggs therein are thus stacked in staggered relation to each other.

A suitable cushioning layer 29 may be provided below the lowermost flat and above the uppermost flat of the pack.

Having thus described my invention what I claim and desire to secure by Letters Patent is:
