WILLIAM GRUI IOW, JR., OF NEW YORK, N. Y.

EQLDING 30x.

Specification of renters Patent.

Application filedDecember 3,1914. Serial No. 875,311.

To all whom it may concern:

-Be it known that I, WI LIAM GRUNOW,

.Jr.,- a citizen of the United States, residing at New York city, in the county of-New York, State of New York, have invented certain new and useful Improvements in Folding Boxes, of whichj the following is a description, reference being had to' the accompanying drawing and to the figures of reference marked thereon.

lhe invention relates to new and useful improvements n folding boxes, and more particularly to a folding box made from pasteboard, or the like, and which is especially designed for shipping articles by parcel post.

An object of the invention is to providea folding box, wherein the body portion, and the cover may eachbe made from a single integral blank folded so as to forma structure which is not only non-leakable, but

which is strong and durable.

A further object of the invention is to provide a box of the above character with spacers for the articles to be shipped and also Withstrengthening' retainers which not only hold the spacers in place, but 'which also strengthen the box longitudinally and transversely. y V

These and other objects will in part be obvious and will in part be hereinafter more fully described. n

In the drawings which show by way of 1 illustration one embodiment of the inven-' tion: Figure l is a perspective view, show- .ing a box embodying my. improvements,

with'the cover separated'from the body portion and theupper retainer broken away to show. the spacers; Fig.- 2isv a longitudinal sectional view through the box on the line 22 of Fig. 3; Fig. 3fis'a transverse sectional view on the line 33 of Fig. 2; Fig.

. {I is a detail in perspective, showing the initial folding of-one ofthe corner flaps; Fig. 5 is a view showing a blank from which either the body portion or the cover may be made, Fig. 6 is aplan view. of one of the retainers; Fig. 7 is a sectional view through one of the retainers and the spacers, show ing the spacers nested on the depressions in the retainers; andFig. 8 isa plan view of a'lolank, showing a strip which may be bent to'form one of the spacers.

The invention consists generally in providing a box, wherein the body portion and the cover portion are similar in construe Patented May 25, 1915.

tion, the end and side walls of the body portion. being of substantially'the same height as the end and side walls of the-cover. Both the cover and the body portion are made from a single integrallblank, which is provided with corner flaps formed integral 'withthe bottom and the side and end walls, so that when the part s'are folded a body portion will be formed which is non-leakable. The same is true of the cover portion and this produces-a box structure which is especially useful for shipping articles by parcel post. I v

The corner flaps are foldable against the inner faces of the side and end walls andare also foldable over the top edges ofv said side and end w'allsand against the outer faces thereof, which looks the corner and holds the parts of the box in assembled position for use. Located within the box are spacers for vided, which retainers are preferably made of reinforced card-board. One of the retainers is also formed with depressions for receiving and holding the spacers and these retainers both fit within the body portion of the boxand conform'to the, shape of the box, so as to strengthen the same transversely and lengthwise thereof.

Referring more in-detail to the drawings, my improved box consists of a body portion 1 and a cover 2. As above noted, the body portion and cover are both similar in construction and therefore a detailed description of one will answerfor the other.

The body portion 1 is formed from a blank indicated at B, Fig. 5. Thedotted lines in this figure show, the lines of fold in the forming of' the box, and said blank folds so 6. The flaps 6 fold on the line ww andalso on the line w g and m-z, see Fig. 5. Said flap is also provided with a slot 7 ,which is in line with the points y-z, and the flap also folds along this line y-z over the npper edges of the side and end walls, as w11l be more fully described. The body portion in V Fig.

formed and scored, if desired along the dotted lines indicated in Fig. 5, is first folded so as to bring the parts to the position shown 4, with the flap within the side and end walls and the sections 8 and 9 are positioned so that they will fold against the inner faces of the side and end walls 3 and 1'. The flap 6 also folds along the center line m-m, so

against the inner faces of the sections 8 and 9 of the flap forming the corner. The upper sectionllof the flap is then folded over the upper edges of the sideand end walls 3 and 4:, and, this section 11 will lie against the outer fabes of the side and end walls 3 and 4:, as clearly shown in Fig. 1. The slot 7 is in line with the'upper edges of the and endwalls and extends a short distance each'side of the central line of fold in the strip and the flap. This slot permits the ready turning of the upper section 11 of the flap over the upper edges of the side and end walls and also serves to hold this section of the flap in the position shown in Fig. 1.

It will be readily seen that both the body portion and the cover may be quickly folded into assembled position and the parts held therein by the construction of the blank itself without any other locking devices. It will also be readily seen that both the body portion and thecover, when in folded or assembled position, are nonleakable.

. Located within the boxis a series of spacers 12. Each'spacer is formed from a single strip, as indicated at S, Fig. 8. This strip is provided *with slots 13, 14, 15 and 1(5 extendinginwardly fromone edge of the strip to a point centrally of the strip" and slots 17, 18 and 19 extending inwardly from the other edge of. the strip to points centrally of the strip. This strip is then bent so that the slot 13 may be interlocked with the slot 18 and the slot 14 is interlocked with the slot 17. The sections ofvthe strip between the slots 14 and 17 form a cylindrical cell 20, whilethe sections of the strip between the slots 13 and 14 form one-half of the cell 21, while the sections of the strip between the slots 17 and 18 form the other The, other end of the half of said cell. spacer is similarly formed by bending the two ends of the strip 22 and 23 meet centrally of the spacer, as clearly shown'inFig. 4. When theslot 13 engages f the strip at the slot 17, it will be understood that the slot 13engages the solid portion of the strip at the end of the slot 17, while'the slot 17 engages the solid portion of the strip at the end of the slot 13, so that when the strip is bentsto form these cells it is bent back upon itself and the edges at each side he in the same plane.

In order to hold the spacers in proper position in the box and also to strengthen that the sections 10-10 will lie side the box, I have provided retainers, and the retainer 24 is formed preferably of corrugated card-board and this corrugated card: board is'put under pressure so as to form depressed portions 25, 26 and 27. These depressed portions are similar in contour this retainer 24-, with the depressionsthere in, is placed in the bottom of the box. The spacers are'then placed. in the depressions in the retainer after which a second'jretainor 28, as shown in Fig. 1, is placed-on top of.

The spacers are preferably of the spacers. such a height that when the retainer 28- is placed thereon, the outerface of said retainer is flush with the outer edge of the box, so that the retainer is wholly within this retainer 24. The retainer 24:,

the upper edges of the box, and, therefore, as

said retainer fits closely to the sideand end walls of the box, said box will be strength ened lengthwise and laterally thereof.

When the cover is in place on the box, the retainers and spacers will be held in assembled position. "The spacers are preferably so constructed that they are separate from each other and the retainers will hold the spacers in this separated position. My improved boxwi's particularly adapted for shipping eggs by parcel post. All egg is placed in each single cell and these spacers hold the eggs completely separated from each other. r V r It is obvious that minor changes in the details of construction and arrangement ,may be made without departing from the I claim as new and desire to secure by Let ters Patents, is: p e

1. A folding box comprising a bottom, side and end walls. and corner flaps formed integral with said bottom, side and end.

walls, said flaps being foldable againstthe inner-face of the side and end walls, and having a portion foldable over the upper edge of said side andvend'walls and against the outer faces thereof, each of saidfiaps having a slot formed therein in line with the upper edges of theside and end walls andextending a short the central line of fold in the flap. 1

' 2. A folding box comprising a body portion and a' cover, said ody portion and cover being similar in construction and having the side and end walls thereof substantially the same height, said body portion including a bottom, side and end walls and distance. each side of foldable against the inner faces of the side and end walls and having a portion foldable over the upper edges of said side and end Walls and against the outer faces thereof, each of said flaps having a slot formed therein in line with the upper edges of the side and end Walls and extending a short distance each side of the central line of fold in the flap.

3. The combination of a box, of spacers located therein for articles to be shipped, said spacers comprising a strip of cardboard having slots adjacent each end and leading from the same edge substantially half way across the strip and a slot at the center of the strip leading from the opposite'edge substantially ha f Way across the strip, and having also interlocking slots between the end slots and center slot, said .strip being bent and interlocked at the slots WILLIAM GRUN OW, JR.
