.Application iled November f considerable distance in l refrigerator cars.

Suchfboxes-,must exhibit a considerable de- `grec.ot-strength in'resisting crushing pres- ,asurefsince theV boxes arestacked vlin the car in-t-iers of considerable height, and -in Vadd-ition Y; to this` and ether-requirements it is desirable .fthatsthe `containers `shall afford some,insulation-against the effect-s of changes in temperature-:as al `protection against such variations as may occur during a longV liourney,.because of thelopening of the car, irregularity in the action of the retrigerating mea-nsv` extreme weather conditions, etc. The air in the refrigerator cars is not only cool, but is very damp, and various articles of' food shipped in such cars, including oranges and other citrus fruit, have more or less natural moisture tending to permeate the material of the container in which the articles are shipped. Corrugated paper board, consisting ot a sheet of corrugated paper interposed between and cemented to opposite facing sheets of paper has of recent years come into extensive use as a material for the construction ot shipping boxes and cartons, and is light and economical and excellent insulating' material, but in all forms of shipping boxes constructed ot' this material which are known to me the construction is such that the walls of the box are relatively weak structurally and are insuliiciently protected against moisture, the effect of which greatly impairs the strength the material would possess if dry, so that when stacked in quantities the lowermost boxes are liable to collapse. The object of my invention is the provision of a corrugated paper board box which shall in the highest degree possible resist the deleterious effects of moisture and have the strength and other desirable qualities adapting it for the shipment of oranges or other fruit or vegetables under the conditions above mentioned. To this end l have designed and invented the novel container hereinafter 2i, i921. serrano. 516,585.

described, and my invention resides, in the` novel structural arrangement and construction ot' the box members, the essent-ialelementsy thereof beingr more Vparticularly pointed out in the appended claims.

Figure l oit the drawing' is a` plan View of the blank ot corrugated paper board of which my box is constructed; Fig. 2 is a perspective of the completedbo-x ready Vtor,

The .same referencecharacters indicate thesame partsinboth figuresof the drawing.

fonry side wall sections,rnumbered'l, 2,."3 and t, respectively, inner wall sections and 6 adapted to be turnedv from the top down upon and pasted `on the side wall sec-- tions l and 3 respectively;

inner Wall sections

7 and 8 similarly turned upward from the bottom and secured to the sides 2 and l.;

bottom closure sections

9 and 10 hinged to the sides 'l and 3 respectively, and top closure sections ll and l2, hinged to the sides E2 and l respectively. The inner wall sections are permanently cemented together, prefer` ably by means of a solution of silicate ot soda which. when dried, is not readily redissolved and Jforms a practically waterproof film or layer uniting the inner and outer sections ot the box sides. At least the outer facing` sheet of the blank is waterproof, and preferably the inner one also.

The

inner side sections

5, 6, 7 and S. Will be noted. are slightly shorter (in horizontal direction) than the sections l, 8 and 4, and the

closure sections

9, 10, l and l2 are correspondingly longer, from which it results that upon pasting the inner side wall sections to the outeriportions there will be spaces between the four inner sections permitting the box to be folded smoothly and without breaking at the vertical edges of the package, The closure sections, on the other hand, will be long enough to Seat over and rest along their side edges upon both sections of the adjacent sides.

The box blank, with the inner side sections permanently secured to the outer sections in the form shown in Fig. 3 and folded flat With the free ends of the sides l and 4f secured together by an ordinary cloth hinge, may be conveniently shipped to As shown in Fig. l the blank includes,

users of such boxes in bundles of any desired number. The boxA is prepared for packing 'by setting it up in square form and securing the bottom tiaps to the side Walls and the meeting edges of such flaps together by suitable adhesive strips ot strong paper or cloth in the usual manner. After being packed the topficlosure flaps are secured in `the same manner as the bottom.

.lt is obvious that my novel shipping box, constructed as above described, is Well adapted to fulil the requirements essential vin a box for the shipment of fruit or similar commodities under the conditions above explained, since the side Walls are of double thickness and are waterprooted both on the inside and outside of: the box as Well as between the two sections, and the horizontal closure members, though of singlethickness are well supported and sufficiently strong to support separat-ely the Weightot thecontents of the individualv boxes. rEhe box also affords a considerable measure of insulation against the eitects of heat and cold, and the pattern is such that it can be most economically manufactured.

I claim:

l. A foldedl sbipping` box formed of cellular paperboardhaving an outer Waterprooi'ed facing` sheet and comprising four connected side Walls, a pair of inner Wall vlular paper board having an outer water? sections connected to the top of two opposite side Walls, a second pair of inner side Wall sections connected to the bottom of' the other two opposite side Walls, said in ner side Wall sections being cemented to said side Walls, a top pair of closure flaps intermediate of and alternating with said tiret-mentioned pair ot inner side Wall sections, and a. bottom pair of closure flaps intermediate of and alternating With said second-mentioned pair of inner side Wall sections.

2. A folded shipping box ormedot celproofed facingV sheet and comprising tour connected side Walls, a pair of inner yWall sections connected to the top ot' two opposite side Walls, a second pair of inner side' Wall sections connected to the bottom of the other two opposite side Walls, said inner side Wall sections being shorter than the side Walls to permit folding Vand beingk cemented to said side Walls, a top pair of clo-v sure flaps alternating Withand correspond` ingly longer than said first-mentioned pair of inner side Wall sections, and a bottom pair of closure flaps alternating With and correspondingly longer than said second mentioned pair of inner side Wall sections.
