PACKING CASE.

^ Application led November 12, 1921. Serial No. 514,537.

To all whom t may concern:

Be itknown that I, WALTER K. DEAN, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented new and useful Improvements in a Packing Casefof which the following is a specification.

The purpose of" this invention is to provide a packing case which may be readily used for packing fragile articles, such as eggs, in such a way that the willl pass through ordinary shipments an particularly in the parcels ost `without breakage. Preferably the case`1s such that the constituent parts are collapsible so that the empty cases ma occupy small space both forshipping an for stora e. In carrying out the invention the co lapsible features, the strength of the receptacle, and the cushioning eect of the pockets are all matters of consideration together with the cheapness of manufacture.

The invention is illustrated in the accompanying drawings as follows Fig. 1 shows a perspective 'view of the case complete.- v

Figs. 2 and 3 plies of corrugated paper from which the outer case is formed.

1 marksthe louter shell. This is made of two plies of corrugatedpaper as shown in Figs. 2 and 3, thefpiece as shown in Fig. 2 being first wound into the shape of theshell,

the folds being shown at a, b, c and d. The.

piece shown in Fig-3 is then wrapped over this first being supplied with adhesive material and preferably the folds are reversed so that the joints are as completely broken as possible. The layers of paper 5 and 6 are then secured to the inner and outer surfaces of these plies. y T'his makes a very rigid construction, the paper preventing the flattening out of the corrugationsfand the reverse direction f the eorrugations giving rigidity in both directions. An inner shell has openings extending through it and is assembled with the outer shell by lacinv it within the outershell, the outer s ell c osing the openings in the inner shell and the side walls ofthe inner shell closing the openings of the Both of these shellsA are collapsible so that they may be readily shipped empty or stored. The pocket pieces 8 are formed .of partition strips 9 which extend in' the .form of a zig zag in parallel diagonal llines and with return bends at the upper and lower edges of the pockets, the strips being provided with f slits or notches 10 at v the crossings so as to permit theinterlapisvcollapsible as shown in Fig. 10. In the l smaller unit 1 the inner shell ordinarily is provided -with aplurality of the pocket4 pieces and the different pieces are separatedy y lseparati plates 12 formed preferably of corrugate paper.

In the structureshown in Fig. 12 and following a larger unit is formed. In this the outer shell P corresponds to the shell 1 and the inner shell 7B-corresponds to the shell 7. Thepocket piece 8a is made u with a plurality of rows'. This is forme by carrying the strips with a plurality of croing in each diagonal direction but the strips ave the return'bends at their upper and lower edges as in the construction shown in Fig.

6. The notching of the strips in order to provide them for a plurality of rows of pockets is illustrated in Figs. 14, 15, 16 and 17 wherein are shown the

strips

9a, 9b, 9c and 9d as formed prior to the assembling and with the lines on which the bending at the top and bottom is accomplished. The case is provided with a plurality of the pocket pieces 8a and these are separated by the separating plates 12R. As willbe seen all the

parts

1, 7a and 8a are collapsible so that these parts" may be put together and readily stored or shipped.

This provides a very rigid packing case so far as resisting crushing strain 1s con-l cerned and at the same time there is suficient cushionin effect to save sucharticles as eggs from un ue breakage.

What I claim is new is:-

1. In a packing case, the combination of a container; and a pocket piece comprising a series of parallel zig zag shaped partition strips extending diagonally across the container' with return bends at the container walls, said strips crossing each other and being oppositely notched and interlapped at the crossings.

2. In a packing case, the combination of a` container; and a pocket piece comprising a series of parallel zig zag shaped partition strips extending diagonally across the container with returif bends at the container walls, said strips crossing each other and being oppositely` notched and interlapped at the crossings, said partition strips having a plurality of crossings in each direction and .forming a series of rows or pockets.

3. In a packing case, the combination of a container; a plurality of pocket pieces each comp-rising a series of parallel z ig zag shaped partition strips extending diagonally across the container with return bends at the container walls, said strips crossing.

eachother and being oppositely notched and interlapped at thecrossings; and separating plates between the pocket-pieces.

4. In a packing case, the combination of a container; and a pocket piece comprising a series of parallel zig zag shaped partition strips extending diagonally across the container with return bends at the container walls, said strips crossing each other and being oppositely notched and interlapped at the crossings, said container and pocket piece being collapsible.

5. In la packing case, the combination of` a container; and a pocket piece comprising a series of parallel* zi zag'shaped partition strips extending diagonally across the container with returnbends at the container walls, saidA strips crossing eachother-and being oppositely notched and interlapped at the crossings, said partition stripsv having a plurality of crossin in each direction and lforming a series o ,rows of pockets, said container and pocket piece being collapsible;

6. In a packing case, the combination of a container comprising two telescoping shells open at their ends, one shell opening in a direction at right angles to the opening of the other when assembled.; and a pocket piece within thel vcontainer comprising a series of parallel zig zag shaped partition strips extending diagonally across the container with return bends at the container walls, said strips crossing each other and being oppositely notched `and interlapped at the crossings.

7. A container case formed of two plies ofcorrugated paper, each ply being wound to form the shell and having its meeting edges extending diagonally across the shell and the corrugations of one shell being in a direction at an angle'to the corrugations of the other shell.

8. A container case formed of two plies of corrugated paper, each ply being wound to form the shell and having its meeting edges extending diagonally across the shell and the corrugations of one shell being in a direction at an angle to the corrugations of' the other shell, the lioints between the edges of the two shells being broken.

. 9. yA container formed of two 'plies of corrugated paper, each ply being folded to form a shell and having its meeting edges extending diagonally across the ply, the slant my hand.
