Wojcik, Chicago, Ill., assigner to international Harvester Company, Chicago, Ill., a corporation of New Jersey Filed Sept. 3, 1964. Ser. No. 394,134 4 Claims. (Cl. 229-37) -or ply wall container which is made from a single blank Iand in which the number of layers comprising the walls ofthe container is uniform throughout their entire lengths.

The requirementrfor such a container exists for ship- Ament of objects needing protection but with a minimum weightr of box board in the' side walls of the container.

lNow, it is apparent that minimum thickness for protection can be procured by using some prior art devices. ;However, in order to obtain a box of such minimum .thickness extensive additional thickness of material must be involved as the prior devices are not of uniform thickness. Of course, such prior constructions are therefore `needlessly costly: First, in the sense that more material `than is actually necessary is used; and second, shipping ;costs may be needlessly high because of inclusion of use- 'less material in containers.

In accordance with the instant invention, the inclusion of funneces-sary material in box construction can be obvviated.

It is an object of the instant invention to provide an .improved construction in a multiple layered or ply wall v'carton or box in which the side walls are -of substantially `uniform thickness and provide substantially uniform cushioning throughout their lengths and widths.

It is additionally an object of the invention to provide such a carton, box or container from a one piece scored blank.l

A yet further object of the invention is to provide an inexpensive-to-produce one piece multiple layered or ply wall shipping container, by reason of minimizing use of material vvin the side walls to that thickness and number of layers only which are in fact required.

The above and other objects, features yand advantages "of the present invention will become more apparent upon `consideration of the following description and appende-d claims, whenconsidered in conjunction with the accom- 'panying drawings, wherein the same reference characters or numerals refer to like or corresponding parts throughout the several views.

FIG. 6 is a reduced plan View of the member which is shown in FIG. 5 and being after formation of the container side walls and before bending of said side walls into final position.

Referring now more particularly to the drawings, it is believed that an understanding of the construction is more easily obtained by first having reference to the blank from which the construction is formed. The blank which is shown in FIG. 4 in plan view is preferably of corrugated or equivalent fibrous board fabrication. It is seen that there are four straight rows which are herein identified by ,the letters A, B, C and D. While the rows A, B, C and D appear in the drawings extended horizontally, in the actual container construction the rows A, B, C and D are disposed vertically. Therefore, for the best understanding of how the container will be formed, one must ment-ally rotate FIG. 4 90 l Now, having furtherreference-to FIG. 4, it is seen that there -arevnine straight columns which, in FIG. 4, extend-from side to side at right angles to rows A, B, C and D. The columns are designated by the; numerals 10, 20, 30, 40, 50, 60, 70, and 90.

By thus identifying the rows and the columns, it is seen that the various sections which are divided by lines of scoring, numerals for which will hereinafter be applied, will conveniently have two coordinates depending upon the row and the column in which each of said sections falls. Accordingly, each of the sections is labeled in FIG. 4 with its coordinates; and when speciiically referring to a particular section in the instant description, such section will be defined or referred to in terms of row and column coordinates.' In other words, for example, all of the sections in row A, in addition to the number designation depending uponthe column in which they are, have applied adjacent such number designation the letter designation identifying the row A. f

The various blank sections heretofore identi-fied are in the most part divided from each other by lines of scoring along which said sections will be creased or folded to formthe container. The lines of scoring dividing columns `10-90 are straight and parallel to each other.

The line of scoring between the column 10 .and Ztl-is designated by the numeral 110. The line ofjscoring between columns 20 and 30 is identified by' the numeral 120. The line of scoring between columns 30 and 40 is designated by the numeral 130. -The line of scoring between the columns 40 and 50 is designated by the numeral 140. That between the columns 50 'and 60 -is designated by the numeral 150, The line of scoring between the columns 60 and 70 is designated by the numeral 160. The line of scoring between the columns 70 and Sil is designated by the numeral 170. And the line of scoring between the column 80 and 90 is designated by the numeral 180. All are `as illustrated in FIG. 4.

Attention is especially invited to the lines of scoring 149 and 150. It is observed that the line indicia employed to designate such lines of scoring is different from the remainder of the scoring lines hereto-fore identified. That is because lines 140 and 150 are distinctive in that they are reverse lines of scoring; that is to say, they provide for folding or creasing which is in a direction opposite to or reverse of that for folding or creasing of the remainder of the lines of scoring heretofore identified between various columns 10-90.

`Between the rows A, B, C, and D and extending from the beginning of column 30 through column 70, there is a` plurality of additional lines of scoring. The additional lines of scoring are parallely to each other and extend `transversely of lines of scoring -180. While such additional lines of scoring extend from side to side, that is, horizontally in FIG. 4, nevertheless, they shall be referred to as vertical lines of scoring.

The said vertical lines of scoring are identified as follows: That which is between the rows A and B is identied by the letter X; that vertical line of scoring which is disposed between or separates the rows B and C is identified by the letter Y; that vertical line of scoring which is between or separates rows C and D is identied by the letter Z.

Between the blank sections A and 20A and 10B and B, there is a vertical slot 111 which in the blank appears as an extension of the line of scoring X. Between the sections lllB and 20B and MC and 20C is a slot 211 which appears as a vertical extension of the line of scoring Y. Between the blank sections 10C and 20C and 10D and 20D Ais an elongated slot 311 which appears as a vertical extension of the line of scoring Z. On the opposite side of the blank, a slot 411 divides columns 80 and into rows A and B, and said slot appears as a vertical extension of the vertical line of scoring A slot 511 divides columns 80 and 90 into B and C sections or rows, and said slot 5,11 appears as a vertical extension of the vertical line Yof scoring Y. A slot 611 divides columns 80 and 90 into Arows C and D, and said slot 611 appears as a vertical extension of the vertical line of scoring Z.

Having thus describedthe various components or blank sections and the means separating them, itis appropriate that adescr'iption o'f the dimensions of the various components be provided as a tool to facilitate a more complete understanding of the invention. lFor orientation,

all dimensions employed in describing the invention will be in terms of the directions in FIG. 1.

Therefore, vertical will be a direction which extends from the top to the bottom ofthe box in FIG. 1, and that dimension will be the one in which the height of the `device is reckoned. Whereas, width will be the dimension which extends perpendicular to the height in a Vertical plane, Such as the plane which is defined by the `lines of scoring Yand Z. Therefore, vthe shortest lineal distance between lines of scoring X and Y would be considered the width Depth,' then, is the remaining dimension; in terms of FIG. 1 it may be characterized as distance in a horizontal plane inward from a wall or vertical plane.

'Now, restated in terms of the `blank shown in FIG. 4, height is the shortest lineal distance between the lines `of scoring whichdivide the blank into columns 3), 449, 50, 60 and 7l). Width is .the shortest lineal dimension whichfdivides the blank 'into rows A, B, C and D. Whereas depth, and in this regard the only sections which have depth within the framework of the definition herein provided are the columns 1t) and 2) and 80 and 90,

yis the shortest lineal distance between the edge 711 and the horizontal line of scoring 110, and also the shortest lineal distance between'the line 110 and the line of scoring 120. `On the other end of the device, depth is the shortest lineal distance 'between the lines of scoring 170 and 180 and also between the line of scoring 180 and the other edge S11 of said blank.

Now then, reference is had to the column 50. The height of each of sections 50A, 50B, 59C and SilD is equal to twice the width thereof. The'width is considered vas one container construction unit. Therefore, each of sections. 50A, SGB, 50C and 50D may be characterized as having an area of two square units of container construction.

With respect to the contains sections in the columns 30, dit, 60 and 70, the height of each of said sections is equal to its width, with the width of said columns equal to the width of column 50. Restated therefore, it may he be said that each of the sections A, 343B, 36C; 36B, A, 40B, 49C, 46D, 63A, lB, 60C, 63D, 70A, 79B, 70C and 7ilD, comprises substantially a square, equivalent to one unit on each side, ergo an area of one square container construction unit.

Now then, reference is had to the columns 10 and Zit and 30 and 9) which form the topof the box and the bottom of the box, respectively. The width of each of sections lilA-llD, 20A-20D, SQA-86D and 90A-90D is equal to one full construction unit. On the other hand, the depth of each of said blank sections which will ultimately make up top and bottom vof the box is only equal to one-half a unit; that is, the depth of the blank lsections which comprise the top and bottom of the -box is one-half its width. Therefore, the area of sections 10A-10D, ZtA-ZQD, SGA-Stil) and A-96D each equals one-half a square construction unit.

Having thus described the details of construction and the preferred dimensions thereof, a description now ensues relative to the manner in which the blank is folded or creased and formed into the container orl box seen in FIG. 1. It is believed that the most clear understanding of the ensuing description will be looking to the blank in FIG. 4.

In the rst step of the box formation, the portion of the blank comprised of columns 1t), 26,36 and 4t) is bent upwardly toward the viewer and then rotated clockwise downwardly upon the remainder of the blank along the reverse line of scoring 140. Next, that portion of the blank comprised of columns 1t), 20 and 30 is bent upwardly toward the viewer and then rotated to the left or downwardly counter-clockwise along the line of scoring 134i, so that column 3) will be lying upon or superposed with respect to column 4). Thereafter that portion of the blank comprising columns 10 and 20 is Ibent downwardly with respect to FIG. 4 at right angles to column 30 and along the line of scoring 120. Then column y1t) is folded back or rotated counter-clockwise along the line of scoring under the column 2li so that the free edge'711 engages the column 3) adjacent the line of scoring 110.

Thereafter, that portion of the blank comprised of columns 60, 70, Sil and 90 is folded upwardly with respect to FIG. 4 along reverse line of scoring 150 and then rotated to the left or counter-clockwise until columns 60 and 7o lie upon column 59. From such position, .but portion of the blank comprising columns '70, Si) and k9) is folded upwardly along the line of scoring andthen rotated downwardly to the right or clockwise to a position in which column '70 will lie or be disposed upon column 6o. Then that portion of the blank comprised of columns 8i) and vSNL is `bent along the line of scoring 170 downward with respect to FIG. 4 to a position which is ,at right angles to column 70. Thereafter, column 90 is bent back `or rotated clockwise under column Ail() along the line of scoring so that the edge 811 engages the column 7) adjacent the line of scoring 17,9.

The appearance of the construction to the `point just described is as illustrated in FIGS. 5 and 6.

In the final steps of the formation of the container or box, each of the rows A, B, C and D is bent v90 from the adjacent thereof along a respective of the lines of scoring X, Y and Z. With the last bending along the vertical lin-es of scoring, the two vertical edges 911 and 912 of the blank will be brought adjacent each other, as illustrated in the cross sectional view of FIG. 3.. A customary or conventional gummed tape or the like may be employe to connect together the edges 911 and 912.

In the final stage of construction or formation, while the rows are being Vbent along the vertical lines of scoring X, Y and Z, those portions of the top which are comprired of sections 1GB and 29B and `10D and 20D 'will be rotated beneath the sections 10A and 29A and sections 10C and 20C. In like manner, sections 80B and 90B sections Stil) and 91N) will be covered by the ,outer bottom portions comprised of sections 80C and 90C and sections 30A and 90A.

From the foregoing, it is apparent that the formed container or box has a heightfof 2 construction units and a width of l unit, so that the area of each side of the box is 2 square units; and that the top and bottom of the box yhad by once againv are each 1 square unit comprising 1 construction unit on each side thereof.

It is further observed that the multiple layered wall container hereby provided comprises side Walls having throughout their area a uniform thickness of plural layers. The device provided by the instant invention also supplies a top and bottom of a uniform number of layers throughout, whereby the requirement for addition or provision of inserts to protect tops and bottoms of fragile objects or other fragile material and the like is obviated.

As many substitutions or changes could be made in the above described construction, and as many apparently widely different embodiments of the invention within the scope of the claims could be constructed without depart- Y ing from the spirit and scope thereof, it is intended that all matter contained in the accompanying specification shall be interpreted as being illustrative and not in .a limiting sense.
