Application filed June 27, 1921.

To all whom it may concern:

Be it known that I, GEORGE E. SoRUnY, a citizen of the United States. residing at Birmingham, in the county of Jelferson and State of Alabama. have invented certain new and useful Improvements in Box Covers, of which the following is a specification.

This invention relates to covers made of paper or pasteboard for boxes made of similar material. In my application for patent filed June 24, 1921, I have shown a" pasteboard box of novel construction and of general octagonal shape, and the primary object of my present invention is to provide a suitable cover for boxes of this kind. The box shown in said application is made from a single folded blank and it is possible to ship a large number of blanks in a fiat condition.

The cover herein shown is also made from a single fiat blank, but the blank is. bent into shape and certain parts are secured together so that the cover may .be quickly opened and held in usable condition before it is shipped. In order to accomplish these objccts the blank is scored and slit to provide a central octagonal top or body portion and eight side portions, four of the side portions being recessed between their opposite ends to faciliate the bending of the sides without distorting them when the top or cover is flattened for transportation.

In the accompanying drawings Figure 1 is a perspective view of a box with the cover embodying my improvements applied thereto. I

Figure 2 is a perspective view of the cover looking at the insidethereof when in open condition ready for use.

Figure 3 is a perspective view of the cover folded and flattened for transportation.

Figure at is a plan View of the scored, re-- cessed and slit blank from which the coveris made.

Figure 5 is a perspective view of'the blank partially bent into shape.

Figure 6 is a perspective view showing the ste s of bending portions of the blank. igure 7 is a perspective view of a portion of the cover showing how certain parts are overlapped and secured.

Figure 8 is a view on an enlarged scale partlyin section and partly in bottom plan showing certain details of construction.

Serial No. 480,608.

The cover A is shown applied to a box B of octagonal form, but while the box and the cover are polygonal they are not necessarilv octagonal. u

As shown in Figure 2, the top or body a of the cover is surrounded by side sections which form the rim of the cover. The sect ons are of the same size, each alternate sections being of double thickness. The in tervening sections of single thickness are recessed as shown at w for a purpose hereinafter described. Figure 2 shows thecovcr ready for use. Figure 3 shows the cover in its folded condition suitable for shipment. The cover may be readily changed from the condition shown in Figure 2 to that shown in Figure 3 as will be hereinafter explained and this may be done without breaking or distorting the material. I

The blank shown in Figure 4 is creased or scored at a to form a central body portion or top c. There are four rim forming flaps C which extend from the body of theblank radially outwards. These four flaps or sections are formed by the slits c and the outer end of each flap is cut away at the opposite corners at 0'. Each flap is scored at so that the outer part of the flap may be doubled over upon the inner portion to thus increase its thickness and strength and also to provide means for holdingadjacent portions of the blank in place.

Intermediate the flaps or sections C are four other flaps or sections D which are separated from the flaps C by the slits c and the flaps D are scored at d on lines perpendicular to the creases a and extend from the joints of these lines outwards. Intermediate its opposite ends, each section D is recessed as mdicated at w.

portant feature of the invention and its purpose is to facilitate in bending the blank while it is being folded to the condition shown in Figure 2 without breaking or distorting the material.

The blank shown in Figure 4 is perfectly fiat and it may if desired be shipped in this condition, but for the convenience of the user or for retail use, the blank is preferably bent into shape and secured and flattened to the condition shown in Figure 3, which is also practicall flat. It is obvious that the blank shown in igure 3 may be quickly bent into condition for use as shown in Figure 2.

This is an ima In order to bend the parts of the blank into shape and to properly secure them, I proceed in the manner indicated in Figures 5, 6 and 7 The first operation is to bend the 5. four sections D on the lines a and to bend the wings D inward as indicated 1n Figure 5. Then the sections C are turned from the position shown at 1 in Figure 6 to the 'ti'on shown at 2 in the same figure. Then the outer parts of the sections 0 are turned over upon the win D and upon the lower portions 0 as indi, ated at 3 and 4 in Figure 6 and then the parts are stapled, ce-

lit)

, mented, or otherwise secured as indicated at w F in Figure 7. When these operations are completed the blank will appear as shown in Figure 2 ready for use, but in such condition the covers would occupy considerable space and in order to avoid this, the blanks are bent to assume 'the condition shown in Figure 3. In thus bending the blank, each section C is turned over upon the middle I portion of the blank and a portion of each section D at opposite ends thereof is bent over upon the interior of the blank while the middle portion of each section D is turned outwards and flattened. It will be observed that when this operation takes place, "each part Dis bent'upon the lines d. The parts above or outside the lines (1 are the I parts that are bent inwards upon the blank while the parts contained within the lines a and d are bent outward. In making these bends, the corners y at opposite ends of the recesses :12 approach each other as indicated in Figure 3. This operation could not be performed if the arts D were not recessed in the manner'be ore described and it will thus be seen that these recesses perform a very important function. The recesses are preferably semicircular, but not necessarily so, it being important that a portion of each flap or section D should be bent outwards, namely, the middle portion, and that portions at opposite ends of each section should be bent inwards.

I claim as my invention: Y 1. A blank for box covers comprising a single piece of material having a body portion, a plurality of side portions formed with wings and which are deeply recessed between the wings and creased on lines extending inwardl from the inner portions of the recesses to t e inner ends of the wings,

posiand other side portions intermediate those first mentioned, each side portion folding with the bottom portion on a fold line which is at an obtuse angle to the fold line on which the adjacent side portion folds with the bottom portion.

2. A box cover made from a single piece of material, having a body portion, side portions formed with wings and which are recessed between the wings, and other side portions intermediate those first mentioned which are doubled over upon themselves and upon the wings and which aresecured to the ings.

3. A blank for box covers comprising a single piece of material having an angular central portion, aplurality of side portions formed with wings and which are deeply recessed between,the wings and are creased diagonally from their inner edges to the inner portions of the recesses, and other side 7 portions intermediate those first mentioned,

each side portion folding with the bottom portion on a fold line which is at an obtuse angle to the fold line on which the adjacent side portion folds with the bottom portion.

4. A box cover made from a single piece of material, having a polygonal central portion, side. portions formedwith wings and which are recessed between the wings, and other side portions intermediate those firstmen tioned which are formed in two sections doubled upon themselves and which are secured 'at opposite ends to the wings.

5. A boxcover flattened and ready for shi ment made from a single piece of materlal having an angular body portion, side portions formed with wings and which are recessed between the wings, and other side portions intermediate those first mentioned which are doubled over upon themselves and 95 upon the wings and secured at opposite ends to the wings, said doubled over side portions beingbent bodily over flatwise. upon the body portion of the cover, andthe remainingside portions having the wings and 10 the opposite end portions bent over upon the central portion of the cover while the middle portions of said recessed members are turned outwards.

In testimony whereof, I have hereunto 1 subscribed f my name.

GEORGE E. scRUBY.
