AMEDEO OIBICI, OF SUFFOLK, VIRGINIA. PAPER- CONTAINER. Application filed March 4, 1920. Serial No. 363,228. To all whom it may concern: Be it known that I, AMnono OBIOI, a citizen of the United States, residing at Suffolk, in the county of Nansemond, State of Virginia, have invented certain new and useful Improvements in Paper Containers, of which the following is a description, reference being hadto the accompanying drawing and to the figures of reference marked thereon. container formed with a foldable closing flap, which, when sealed, provides a closed paper receptacle. Referring more particularly to the accompanying drawings Figure 1 represents an ordinary piece of paper, the diagonal thereof indicating the line On which it is folded; Fig. 2 shows the paper thus folded, the dotted vertical line indicating the line on which one of the apices is folded inwardly; Fig. 3 shows the next step, such apex having been folded inwardly the dotted line in dicating the point at which the other diagonal apex is folded inwardly; Fig. 4 shows these diagonal or base apices interfolded in position; Fig. 5 is a perspective of the rear face of the container showing the double upstanding flaps before one of the same is folded downwardly Fig. 6 shows one of such flaps folded and sealed in position, forming a complete container; and Fig. 7 is a sectional view on the line 77 of Fig. 6. In general, the invention embraces an envelop type of paper container comprising 7 an open mouth receptacle provided with an integral foldable sealing flap, made by folding a square piece of paper diagonally to form a double triangle, next folding inwardly the apices of the triangle adjacent the diagonal into overlapping position so that the apex of one will lie within the double fold of the other, then folding inwardly one of the remaining apices of the original triangle, so that the edges thereof substantially meet the edges of the inwardly folded apices leaving the other apex of the remaining triangle, which will form the closing flap, in its original upstanding position, then securing in position the inwardly folded portions or apices whereby to form the container described. This container may then be filled as desired, the flap folded down and sealed. The container is made by folding a sub stantially square sheet 1 of paper of any size, along the diagonal indicated in dotted lines at 2 to form a double triangle having the folds 8 and 4. With the diagonal 2 as a base, the base or diagonal apices 5 and 6 are folded inwardly along lines transverse to the diagonal, such lines being indicated in dotted lines in Fig. 2 at 7 and in dotted lines in Fig. 3 at 8, and being preferably at points substantially one-third the length of the base or diagonal. These inwardly folded base or diagonal apices 5 and 6 are next interfolded as shown in Figs. l and 5 by inserting the apex of one within the double fold of the other to hold them in position. As shown in Fig. 5, the container has now as .sumed a rectangular shape, preferably square, with two upstanding triangular flaps 9 and 10 integral with the body. These flaps 9 and 10 are in fact the flaps of the remaining apex of the original triangle shown in Fig. 2, that is to say, these flaps 9 and 10 are the folds of the only remaining apex of the original triangles 3 and 41 that have not been as yet folded. The rearmost one of these folds, that is, the apex 9 is now inwardly folded to a point where its edges 11 and 12 meet or substantially meet the edges 13 and 14 of the inwardly folded apices 5 and 6 as indicated in Fig. 6 and these inwardly folded portions or apices are now sealed in any desirable manner, such as by pasting the same with mucilage, or by a metal fastener, or by a niucilage stamp, the latter being indicated at 15 in Fig. 6. There is now completed a paper container forming an open-mouthed receptacle provided with an integral foldable closing flap 10 which as clearly shown in Figs. 5, 6, and 7, is the only remaining apex of the original triangle which has not as yet been folded. After the contents is inserted into the container, this flap is folded inwardly to 7 closed position and is sealed in any desired manner. It will be noted that such a container has been formed of a substantially square sheet of paper, without any cutting operation, and by the simple interfolding of the parts. Having thus described the invention, what I claim as new and desire to secure by Letters-Patent, is 1. A finished paper container formed from a substantially square piece of paper by folding the same diagonally into a double triangle, folding the 'aplces adjacent thev angular flap of single thickness forming a foldable closure therefor. 2. A "finished paper container formed from a substantially square piece of paper by folding the same diagonally into a double triangle,- overlapping the apices by folding the same inwardly along the diagonal, interfolding such apices one within the other, folding one only of the remaining apices of the original triangle inwardly and securing such inwardly folded apices whereby to form an open mouthed container, the other remaining apex of the original triangle forming a foldable closing flap therefor. 8. A finished paper container formed from asquare piece of paper by foldingthe same diagonally into a double triangle, folding the apices inwardly along the diagonal each at a point substantially one third of the length of said diagonal, inter-folding such apices one within the other, folding one only of the remaining-apices of the original triangle inwardly to substantially meet the edges of the interfolded apices and securing such inwardly folded apices in position whereby to form an open-mouthed container the other remaining apex of, the original triangle forming a foldable' closing flap therefor. In testimony whereof, I aflix my signature. AMEDEO 013101. Referenced by
