SECTOR-SHAPED CARTON.

SPECIFICATION forming part of Letters Patent No. 756,494, dated April 5, 1904.

Application filed August 24, 1903- candy or the like in pails and which are made of a single flat blank cut to the proper shape and having its parts joined by the use of paste or glue to form a tubular body and connected bottom wall, which may be folded fiat for transportation, but which may be readily set up for use.

The invention consists in the matters hereinafter set forth, and more particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 illustrates a blank for forming a carton madein accordance with my invention. Fig. 2 is a perspective View of the carton when folded and ready for use looking upwardly at the bottom thereof. Fig. 8 is a perspective view of the carton when folded and ready for use looking downwardly into the interior of the same. Fig. 4 is a side view of the carton when the parts thereof are joined by pasting and the same is folded flat for transportation. Fig. 5 shows the blank after the ends of the tubular part or body-have been joined by pasting and when the folding flaps or sections which constitute the bottom are in their extended or unfolded position.

The blank illustrated embraces four connected main sections A B (l D, which constitute the tubular body of the finished carton and are separated by score-lines (0b 0 d, an end or pasting flap E, joined to the section D and separated therefrom by a score-line cl, two triangular bottom-sections F and Gr, of which the section F is connected with the main section B and the section G is connected with Serial No. 170,514. (No model.)

an extension of the bottom flap G. The gusset-sections H and I are separated from the body-section C and bottom-section F by scOrelines 71 and 2' and from each other by a scoreline it. The gusset-section J is separated from the bottom-section G by a score-liney' and from the gusset-section K by a score-line is. On the bottom margin of the body-section A is a pasting-flap L, separated therefrom by a score-line Z, and on the bottom margin of the body-section Dis a pasting-flap M, which is separated from the same by a score-line m. The bottom-sections F and G are alike in shape and together correspond in form with the bottom of the carton, and said sections constitute the bottom wall of the carton when the same is ready for use, as clearly seen in Figs. 2 and 3. The gusset-sections H and I are also alike in shape and are joined to and fill the triangular space between the bottom margin of the bodysection C and the adjacent margin of the bottom-section F, the side margins of said gusset-sections (indicated by the score-lines l1 and i) being of corresponding length, while the score-line it, which divides the Said gussetsections H and I, subtends the angle between said score-lines h and c'. The gusset-sections J and K correspond in shape with the said sections H and I, the side margin of the section J, which joins the section G, being of the same length'as the side margin of the section I, which joins the section F, while the score-line la subtends angle between the scoreline j and the corresponding outer margin of the section K. The sections A and B constitute the diverging walls of the sector-shaped carton, while the sections 0 and D form the outer or are walls thereof, the width of the sections C and D being equal and the united widths of the sections B and C being equal to those of the sections A and D. The parts of the blank thus made are permanently joined or pasted by folding the section D along the score-lines 0 against the section C and likewise folding the section A along the scoreline (4 against the section D and then securing the pasting-flap E to the outer margin of the section A. The parts will then be in the po sition shown in Fig. 5. The sections Gr,-I, and K are then folded upwardly and against the sections F, H, and J along the score-line g and the pasting-flap M then pasted to the margin 7a of the section K and the flap L on the section A also secured to the adjacent margin g of the bottom-section G. The parts will then be in the position shown in Fig. 4, the blank then being in its knockdown or folded form and ready for shipment or transportation.

In setting up or placing in readiness for use the blank shaped, folded, and pasted in the manner described the sides of the tubular body of the blank are spread apart by drawing apart the same at the score-lines d and 6, this movement tending to straighten out the bottom-sections F and G. Before the body of the blank I reaches its fully-expanded form, however, and

while the said bottom-sections F and G still stand at an angle to each other the triangular connecting parts or folding gussets formed in one instance by the gusset-sections H and I and in the other instance by the gusset-sections J and K are folded upwardly into the interior of the'carton, this being accomplished by pressing inwardly on the parts at the scorelines h in. The gusset-sections are in this operation folded together or against each other along the said score-lines it and in, and said gusset-sections are bent into angular relation to the parts with which their outer margins are connected on the score-lines h d and jm. After the triangular gusset-sections J K and H I have thus been folded inwardly the side Walls are drawn farther out and the bottomsections F and-G pushed upwardly until said gusset-sections J K and H I are pressed flat against each other and rest closely against the upper or inner surfaces of the sections F and G, as clearly seen in Fig. 3, when the carton will be in condition for use.

'It will be understood that the bottom of the carton made as described will be of ample vented by the contents of the carton, but because downward pressure coming on the inturned gusset-sections J K and H I will have little effect in forcing downwardly or out- Wardly the bottom-sections, in view of the fact that the sections K and H are directly attached to the Walls C and I) and are support ed by said walls from downward movement, as will be readily understood from an inspection of Figs. 2 and 3.

I claim as my invention 1. A blank for sector-shaped cartons embracing a body portion which is divided transversely by score-lines into four main sections adapted to form the radial Walls and are walls of the carton and is provided on two of said sections with a flap for forming the bottom of the carton consisting of two triangular sections, shaped to conform to the bottom of the carton and two pairs of gusset-sections forming extensions of the two triangular bottomsections adapted to be folded inwardly inside of the bottom-sections; thesaid blank also having pasting-flaps for joining one of the bottomsections to one of the body-sections and for joining one of the gusset-sections to one of said body-sections.

2. A sector-shaped carton comprising two radial walls and two are Walls, which walls are joined to form a tubular body, a bottomwall embracing two triangular bottom-sections which are joined to each other and to the radial walls of the tubular body, and two triangular pairs of folding gusset-sections, each pair of which is attached at one edge to one of the bottom-sections, and at its other edge to one of the arc walls of the tubular body.

In testimony that I claim the foregoing as my invention I affix my signature, in presence of two Witnesses, this 15th day of August,

JOEL C. GRAHAM. Witnesses:

CHAs. W. WHITTAKER, CHAS. HINoHMAN.
