PAPER BAG.

Specification of Letters Patent.

Patented Apr. 3, TQTT.

Application filed. December 21, 1916. Serial No. 138,248.

To all whom it may camera.

]Be it known that I, EDWARD N. SIMO- NEAUX, a citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Paper Bags; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains' to make and use the same.

This invention relates to improvements in paper bags, and more particularly to those. having what are termed satchel bottoms.

The object of the invention is to provide a bag of this character formed from a rectangular sheet of material so folded and out that a satchel bottom is produced composed of two-ply fabric and in which the bottom seam is overlapped on both sides by reinforcing flaps, thereby rendering it very strong and capable of withstanding heavy strains, and which is so constructed as to form three longitudinally alined substantially diamondshaped members on the bag bottom when the bag is in collapsed inoperative position.

In the accompanying drawings:

Figure 1 represents a plan view taken from the inside of the blank from which this improved bag is constructed;

Fig. 2 is a similar view with the upper portion of the blank broken away showing the first step in the folding operation of the blank;

Fig. 3 is a similar view with the blank partly folded;

Fig. 4 is a similar view showing a still further folding of the parts;

Fig. 5 is a similar view showing the bottom of the bag in completed condition; I

Fig. 6 is a vertical section taken on the line 6-6 of Fig. 3; and

Fig. 7 is a perspective view showing the completed bag opened up ready for use.

In the embodiment illustrated, a rectangular sheet 1 of Manila or other paper is shown which is folded from end to end are folded toward each other along said lines the edges 4 and 5 will lap a suitable distance about an inch more or less, and these edges are united in lapped relation by sealing or with line 8 and extend to line 9 where they meet lines 12 and 13 which converge and intersect with each other and with lines 2 and 3 at a point spaced from line 9 a distance equal to the distance from line 9 to the point where lines 10 and 11 intersect lines 2 and 3.

The lower edge of the blank is provided with two pairs of inwardly converging adjacent slits 14 and 15, said slits being formed parallel with the planes of the lines by folds 10 and 11 and terminate at their intersection with lines 12 and 13 forming complete one piece truncated triangular flaps 16 and 17 which are designed, when the blank is folded to form the bag, to extend toward each other with their wide free edges abutting as shown in Figs. 5 and 7. Lines of fold 18 and 19 extend from the points where lines 10 and 12, and 11 and 1? meet and are arranged parallel with lines 2 and 3, and when the blank is folded to form the bag these lines 18 and 19 ali ne with each other transversely of the bag bottom.

. In forming the bag bottom from the relation forming the lines of fold 9 withv the flaps 16 and 17 extending outwardly thereby forming the fold lines 12 and 13. The flaps 16 and 17 are then folded toward each other thereby forming the pairs'of reg istering fold lines 18 and 19. When in this position the edges of the flaps 16 and 17 abut and three alining substantially diamondshaped bottom members 20, 21, and 22, are formed, the bag then being in collapsed folded position for storing.

The overlapping edges of the lower end of e the tube extend longitudinally of the bottom thereof and are gummed and are secured together by Wetting the gum in the usual manner. The flaps 16 and 17 are also gummed on their inner faces and are secured to the flat overlapped bottom edges of the tube, effectually covering the seam at the bottom and forminga reinforce therefor, the bottom being of double thickness from the linesof fold 18' and 19 at each end of the bag bottom proper so that when the bag is opened for use a rectangular bottom of double thickness will beformed.

The bag may be closed at its top by the usual or any suitable means.

I clainz: 1. A paper bag comprising a blank cut and creased to fold into bag form with the edges of its bottom overlapping and adhesively secured forming a longitudinal seam, complete one piece flaps extending toward each other longitudinally of said edges, and overlapping both sides of the seam formed by said edges, and adhesively secured thereto with the free ends of said flaps abutting.

2. A paper bag comprising a rectangular blank folded to form a flat tube with its side edges overlapping and adhesively secured, one end of said tube having two pairs of inwardly converging slits, the slits of each 'pair being adjacent to each other forming complete one piece truncated triangular flaps adapted, when the blank is folded to form the bag, to extend toward each other withtheir .free ends abutting, the bottom edges of said bag being overlapped and adhesively secured, said flaps extending longitudinally of and lapping said edges.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
