CORRUGATED-PAPER-BOARD BOX.

Specification of Letters Patent.

Application filed July 29, 1918. Serial No. 247,102.

Board Boxes, of which the fo lowing is a specification.

My invention relates to boxes constructed of double-faced corrugated paper board or equivalent material, and has for its object the production of a box particularly well adapted for the shipment of small lots of canned goods, such as canned fruit, vegetables or other food ordinarily put up in tin cans, and also adapted for the shipment of other articles of similar cylindrical or other regular shape, such as bottles or pasteboard boxes which are circular or polygonal in cross-section and which it maybe desired to package in small lots, such as a half dozen or a dozen in a package. In carrying out my invention I have employed two blanks, both of which are rectangular in shape and can therefore be cut economically, and have so proportioned and arranged the box members that the box includes an oblong outer box of double thickness at its bottom and top, separated by a transverse partition which is braced against the members of the outer box and forms a support for the outer top and bottom members. With the foregoing objects and advantages in view I have designed .and invented the box structures illustrated in the accompanying drawings and hereinafter described, the essential element of my invention being more particularly pointed out in the appended claims.

Of the drawings, Figure 1 is a plan view of the larger blank used in constructing a preferred form of my invention, lines of out completely severing the material being indicated by full lines and folding lines being shown by dotted lines; Fig. 2 is a similar view of the smaller blank; Fig.3 is a perspective of a box filled with cans and partially closed, parts being broken away to better show the arrangement and relationship of the parts; Fig. 4 is a longitudinal section of the box; Figs. 5, 6, 7 and 8 are views of a modified form of box, said figures corresponding respectively to Figs. 1, 2, 3 and 4-; Fig. 9 is a longitudinal vertical section of a slight modification of proportions of theform of box shown in Figs. 1 to 4,

inclusive; and Fig. a similar section of a modification of proportions of the box shown in Figs. 5 to 8 inclusive.

The same reference characters indicate the same parts in all the figures of the drawing.

The box which is shown in Figs. 1 to 4, inclusive, is designed for the reception of a half dozen cans, arranged in two rows of three cans each, and the end portions 1, 1'- of the rectangular box blank (see F ig. 1) are therefore two-thirds as long as the

side portions

2, 2, the length of the ends being twice the diameter of the cans intended to be packed in the box, and the sides being three times such diameter. the

portions

1 and 2 is equal to the height of the cans. The bottom closure comprises outer portions or flaps 33, each one half as wide as the ends 11, or one diameter of the cans, and inner portions or flaps l4 of the same width. The but edges of the end 1-" and side 2 are united by a cloth pasting strip 5, or equivalent means, and the inner bottom portions 4;4 folded inwardly toward each other, after which the outer bottom portions 38 are folded upon and. glued to the portion l land their meeting edges further secured together by a pasting strip 6. Preferably a pasting strip (3 is also applied at each end of the folded box to unite the side edges of the outer bottom flaps 33 and the

ends

1, 1 of the box and afford additional strength as well as afford a neat finish.

Hinged to the

sides

2, 2 are the outer cover flaps 77 of the same size as the outer bottom portions 38, and hinged to the

sides

1, 1 are the inner cover flaps 88 of the same size as the innerbottom portions ll, the flaps 77 and 88 constituting the top closure of the box.

It is evident that the inner bottom portions or flaps la l and the inner cover flaps 88 being each of a width equal to the diameter of a can. there will be left between each pair a space or gap also equal to one diameter which is filled by the top and bottom members of the partition structure which will next be described. This partition structure is formed of a blank (see Fig. 2) .which is transversely scored to provide a horizontal bottom portion 9 of a width equal to one diameter of the cans. and which will therefore fit exactly into the gap between the inner portions -ll of the folded outer The width of t3 Ii box: a vertical partition wall it) as wide as the sides and end of the box proper. that is. the height of the cans; a horizontal top porlion 11 ot' the same size as the bottom 9 and which will therefore tit between the top cover flaps 8-$z and meeting vertical flaps 12-12 connected one to the bottom portion 5) and one to the top portion 11 which are together equal in width to the vertical partition and constitute a second vertical partition wall. llowerer. this exact arrangement of the parts of the desirable. is not a neeessam one. since the important requisites to the formation of an ett'ective partition are merely that it Shall include top and bottom portions arranged to till the spaces between the por ions 4l and 8% of the box proper and an intermediate vertical portion extending between the closures of the box.

It will be understood that the bottom closure having been formed as described. the partition structure is inserted as shown in Fig. 3 and the articles to be packed in the receptacle are inserted. The inner cover tlaps are now folded down into the same plane as the top portion of the partition structure and the outer cover flaps then glued down upon such inner cover tlaps and top partition member. The partition blank in the folded and closed package will form a transverse rectangular tube having its bottom fitting snugly between and in the same plane as the inner portions 4'-l ot the outer box and its top iitting in the same manner between the inner top cover flaps of the outer box. the vertical partition wall 10 and the wall formed of the abutting flaps 12-42 extending between the bottom and top cover portions 3-3 and 7-7 of the outer box and affording them very substantial support. The partition. thus restrained from lateral movement, prevents the entire weight of the contents of the box from being thrown wholly against either end, while the top and bottom closures are strengthened against crushing stresses.

The box illustrated in Figs. 5 to 8 inelusive is adapted to hold a dozen cans or other articles, one-half on each side of the central partition. the entire lotbeing ar ranged in four transverse rows of three cans each. It follows from this arrange ment that the top and bottom portions of the box blank (the parts of which are nnnr bered the same and are identical in arrange ment and vary only in proportions as com pared with corresi'ionding parts of the form of box first described) are each of a width equal to one and one-half times the. diameter of the cans, leaving a central space be tween inner bottom flaps 44 andv inner cover flaps 8'9 equal to one diameter and extending from the middle of the second to the middle of the third row of cans.

partition blank, although.

mg an intermediate gap, and

The partition wall used in the modified form of my invention is formed by the central portion 13-l3 of two identical partition blanks. the portions 13 being each hinged at top and bottom to a top flap 1i and a bottom flap 15. These portions 14. andlfi are each of a width equal to one-half the diameter of can, so that when arranged in the assembled box as shown they'will completely fill the space between the inner bottom portions and top cover portions of the box proper. The bottom flaps 15 are preterably glued to the outer bottom flaps 3-2) of the box, though this is not absolutely necessary.

It is obvious that variations in the proportions of the box embers may be made in adapting my in. i on to diti'erent requirements. For instance. it the package is designed to contain ten cans arranged in two rows of five! each. the end tlaps will extend over the end cans at each end and the partition member will be constructed to inclosc the six cans intermediate the end cans as shown in Fig. 9. It it be desired to pack fifteen cans in a package, the box shown in Figs. 5 to 8 may be modified by lengthening it, and lengthening the top and bottom flaps of one of the partition members to extend over one and one-halt diameters of the cans, the partition wall in this case being arranged a little to one side of the center and the compartment on one side containing six cans and on the other nine, as illustrated in Fig. 10. My claims. therefore. are not to be limited to the exact. arrangement and construction shown in the forms of my invention hereinbefore particularly described.

I claim:

1. A rectangular box of the character described and comprising a box proper provided at top and bottom on two opposite sides with meeting outer closure flaps and on the other two sides with inner closure flaps extending toward each other and leava partition structure comprising a vertical wall provided with connected top and bottom members arranged to fill the gap between said inner closure flaps.

2. A rectangular box of the character described and comprising a box proper provided at top and bottom on two opposite sides with meeting outer closure flaps and on the other two sides with inner closure flaps extending toward each other and leaving an intermediate gap, and a partition structure comprising a bottom portion arranged to fill the gap between the inner hottom closure flaps of the box proper and a connected vertical wall and a connected top portion arranged to fill the gap between the top closure of the box, said bottom and top portions being provided with meeting 13( name 7 B flaps arran ed to together constitute a second vertica partition wall.

3. An oblong box of the character described and comprising a box proper hav- 5 ing connected sides and ends provided at top and bottom on its two sides with meeting outer closure flaps and on its two ends with inner closure flaps of the same width extending toward each other and leaving an intermediate gap, and a partition struc- 10 ture comprising a" vertical wall and a connected horizontal portion arranged to fill the gap between said inner closure flaps.
