" PAPER BAG Filed May 21, 1930 Patented Oct. 6, 1931 2 UNITED STATES ISABELLE B. BLAKE, 01! NEW YORK, 11'. Y.

PAPER BAG Application filed Kay 21, 1980. Serial R0. 454,898.

This invention relates to receptacles and the improvements are directed to a novel form of paper bag formed from a single piece of material.

Primarily, the object of the present invention resides in the provision of a blank for forming a bag of the above-mentioned character, said blank being provided with indica: tions, in the form of lines, or the like, whereby said blank may befolded to produce a bag having an oblong bottom devoid of seams.

A subsidiary object is the arrangement of additional lines whereby the formed bag may be collapsed or folded to assume a compact form to facilitate the shipment" or handling thereof.

An additional object of the invention isthe provision of a blank which is susceptible of variance in order that formed bags having desired dimensions may be produced.

With these objects in view, together with others whichwill appear as the descriptionproceeds, the invention resides inthe novel formation, combination and arrangement of parts, all as will be described more fully here- 4 lnafter, illustrated in the drawings, and particularly pointed out in the claims.

In said drawings: v Figure 1 is a view of the blank from which the bag is formed, the dot and dash lines indicating the lines on which the material is folded.

Fig. 2 is a fragmentary view illustrating one step in the folding of the blank.

Fig. 3 is a similar view showing one end of the bag completed.

Fig. 4 is a perspective view of the completed bag. I

Fig. 5 is a View showingthe bag partially collapsed; and a V Fig. 6 is a view showing the receptacle completely collapsed.

Referring now more in detail to the accompanying drawings, wherein like characters of reference indicate similar parts throughout the several'views, let A denote the blank, and upon inspection of Fig. 1 it will be observed that said blank is provided with a series of lines which indicate the lines on which said blank is folded. Said lines have been designated by certain numerals arranged sequentially in the order of folding, as will presently appear, but at this time it is pointed out that the bottom of the completed bag is bounded by lines 12, 14, 18 and 21, whereby the desired oblong structure is produced. Lines 21 and 13, arranged at right angles to said line 12, and lines 17 and line 10 coincides with line 14, as indicated in P Fig. 2. Certain parts are now in an erect position as'shown in said figure. Next the lines 15, 15a, 16, 17 and 18 are folded upwardly and inwardly until said line 16 coincides with line 14, whereupon the overlapping portions B, (see Fig. 3) may be pasted together to maintain the parts in the erect position shown. One end of the bag is now formed.

The formation of the other end of the bag is similar to that just described in that lines 19, 19a, 20 and 21a are folded upwardly and inwardly, line 20 coinciding with line 21a, and finally lines 22, 22a, 23 and 24: and similarly folded, said line 23 coinciding with line 21a and with the overlapping portions pasted, the bag is substantially completed. It

7 will be noted the foldings just described, have produced flaps C and D which are now folded upwardly against the sides of the bag, and pasted thereto-to complete the structure.

From the foregoing it is apparent that the formed bag is provided with an oblong bottom portion and the latter is devoid of seams of any sort. In view of this solid bottom, said bag may be snugly engaged within a garbage can, or the like, for the reception of waste material.

As previously pointed out, it is desired to provide means whereby the bag as a whole may be collapsed to assume a compact arrangement whereby packing and shipmentis facilitated. To this'end'diagonal fold lines D Y 26 and 30, and diagonal lines 27 and 31 are provided, the first pair of lines cooperating.

- ,withsaid lines and to form a square,

while lines 27 and 31 cooperate with lines 19 and 22 to'form a square, the intersections of said pairs of diagonal lines being connected byline 25.' In addition to the foregoing,

blank is provided with a series of transverse lines which are designated generally by the numerals 29-33, 34':35, and 28-32. When collapsing the formed bag, the 11116 is pressed inwardly, the bottom thus foldcollapsed bag shown in Fig. 6. ,In this'coneated inFig. 4..

is to be understood that the invention is not dition the bags are ready for shipment and when a, bag is tobe used the samemay be conveniently unfolded to the position indi- While the present referred embodiment 'of the invention, it
