and end walls will extend substantially at right angles to the base or main wall of the container.
In the art there has been considerable development in the provision of knock-down paper containers of the type referred to in which the side and end walls are formed with diagonal folds which when the container is in knockdown condition makes each end of the container frusto-triangular in shape. Many users of this type of package prefer that the folds of the side and end flaps at the ends of the container will lie flat with the end wall of the base of the con-' tainer and this results in it sometimes being necessary to make the containers with the frustotriangular ends and then to refold them so that I the end wall together with the diagonally folded pairs thereof will extend in and lie flat against the bottom wall of the container.
The manufacture of diagonally folded knockdown containers of the type noted further requires a difiicult diagonal folding operation which it is one of my objects to avoid.
It is the particular object of my invention to provide a knock-down container which will fold fiat and which will have ends which extend at right-angles to the sides of the infolded sides of the container and which also may be readily manufactured on a simple folding machine and which will not require any diagonal folding of the ends or corner flaps.
Broadly it is the idea of my invention to provide a container which will require a side folding operation, a glue-spot applying operation and an end folding operation.
In my previous reference to the folding of the sides and ends of the container, I use the terms sides and ends arbitrarily to indicate opposed walls because in the case of a square package, the size of the sides and ends will be equal.
Referring to the drawings:

the blank is folded in the manner illustrated. Figure 5 is a plan view of a modified type of blank, having cut and scored comer end flaps. Figure 6 is a plan view of the blank shown in Figure 5 after the end folding operation.

Figure 9 is a plan view of another modified type of blank in which the corner flaps are cut and scored.
Figure 10 is a plan view of the blank after th sides are folded in.
Figure 11 is a plan view of the container after the sides are folded in.
Figure 12 is a perspective view of the type of container shown in Figures 9 to 11 after it is set In describing the various modifications in my new type of box, I-will first refer to the modificationshown in Figures 5 to 8 and in Figures 9 to 12 because the modification shown in Figures 1 to 4 are susceptible of folding operations in different sequences, while the modifications in Figures 5 to 8 and in Figures 9 to 12 must be folded in a prearranged manner.
In Figure 5 I have shown a blank having a bottom wall A, side walls B and end walls C. Corner flaps D are articulated to the side walls B, as indicated at iz--a and these flaps have diagonal fold lines a--b formed by the usual scoring operation.
The first operation in forming the container from the blank shown in Figure 5 is to pass the blank through a folding machine which turns over the end flap C and corner flaps D causing these flaps to lie fiat over the bottom wall A of the container. With suitable spot-glue applying 95 mechanism 1 to apply the glue over a desired area of the inwardly folded flaps, glue or suitable adhesive is applied to the triangular areas indicated at E--E.
The blank is then usually passed in the direction at right-angles to its movement to the endfolding operation and the sides B-B together with the end folded corner flaps D are folded over so as to lie flat against the bottom of the container. With the folding over of the side 105 walls, the glued area E of the corner flaps will adhere to the space indicated at F-F on the outer side of the infolded end walls.
To open up the container for use all that is necessary is to pull out the end wall C. The side n walls B will then stand erect and the corner flaps will fold along their diagonal score lines permitting the end wall C to stand in upright position at right-angles to the bottom wall in a plane and at right-angles to the side walls in another plane.
Referring now to the modification shown in Figures 9 to 12, the bottom wall of the blank is indicated at A the side walls articulated to the bottom wall are indicated at B and the end walls articulated to the ends of the bottom wall are indicated at C The corner flaps D are articulated to the end walls as indicated at a--a' and the corner flaps are provided with diagonal fold lines indicated at a-b'.
The first folding operation in this modification is performed when the blank is moved in the direction of its length and in which the side walls B together with the corner flaps D are folded over to lie fiat against the bottom wall of the blank.
By means of spot-glue applying mechanism, triangular areas of adhesive are applied to the infolded corner flaps in the space in the area indicated at E The next folding operation illustrated in Figure 11 is to fold over the end walls C of the blank which will cause the adhesive to adhere to the areas of the outer surfaces of the side walls indicated in Figure 10 at F In opening up this modified type of blank, the end walls are raised to an upright position which will carry the side walls also to upright position and the container will be ready for use.
Referring to Figures 1 to 4, we have shown a blank having a bottom wall A side wall B and end walls C The corner flaps have diagonal folds, 11 -1) and are articulated as indicated at a a and a-c to both the side and end wall.
I have indicated the manner of folding this modification of blank in a way similar to the folding of the modifica ion shown in Figures 5 and 8 although by the application of the adhesive to different areas of the corner flaps, the same manner of folding shown in Figures 9 and 12 may be employed in which case a container which when set up, will have the appearance of the container shown in Figure 12 instead of that of the container shown in Figure 8.
Figure 2 shows the blank shown in Figure 1 with the sides C folded in against the bottom wall of the blank. Adhesive is then applied to the triangular areas of the outer surface of the infolded corner flaps as indicated at E The side walls B of the blank are then folded in against the bottom wall and the -adhesively coated area E adheres to the outer surface of the end walls indicated at F Opening up the infolded blank illustrated in Figure 3 by pulling out on the ends C the side walls B and the end walls C will stand upright at right-angles to the plane of the bottom A and the corner flaps will form a triangular fold exteriorly of the end walls.
It will be obvious that by applying the sequence of folding operations illustrated in Figures 9 to 12, a blank similar to that shown in these figures may be formed from the blank shown in Figure 1 in which the side walls extend along the sides of the container with the corner flaps formed in a diagonal fold outside the ends of the sides.
All of the modifications illustrated may be readily folded in two simple folding operations, without the necessity of any diagonal folding of side or end flaps which is a much more simple operation than as previously been required and which may be formed on a simple envelope folding machine without the necessity of diagonal folding mechanism.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
1. A knockdown container comprising a rectangular bottom and four walls upstanding from the respective edges of the bottom, two opposite walls having at their respective ends slits leaving square flaps separate from and folded across the outer sides of the respective adjacent other walls, each flap also being folded inwardly on a line from its innermost to its outermost corner, forming an inner triangular half between its other half and the adjacent wall, and this inner half being fixed to said adjacent wall.
2. A four-walled knock-down container comprising a rectangular sheet having pairs of slits extending in from opposite edges, leaving rectangular corner flaps and forming two opposite wall members each between and separate from each two corner flaps, with each corner flap having one triangular half folded onto the other on a diagonal line beginning at the outer corner next to the adjacent slit, and each wall member folded in the same direction on a line joining the inner ends of the two adjacent slits, onto the adjacent portions of the sheet, and with the other two opposite edge portions of the sheet folded in the same direction on lines joining the inner ends of the respective adjacent slits, to form the other two opposite walls of the container, with said infolded triangular portions rigidly secured to the inner corner portions of said first two infolded walls, whereby substantially registering edges of the parts thus secured together form compact substantially rigid frictional bearings against said other two wall members when the container is set up, without tendency to spring open, whereby the container is held in set-up condition.
