PAPER BAG.

Application filed May '7, 1926. Serial No. 107,425.

' rangement thereof as hereinafter described plete bag;

and claimed.

A prime object of the invention is to provide in conjunction with a bag proper a single cord for supporting the same and which is so arranged with relation to the side walls and the bottom wall of the bag as to effectually brace the bottom wall where the greatest strain occurs when the bag is filled.

I-Ieretofore it has been the practice to support the bag by different cord arrangements, as where an endless cord is threaded through openings in the sides of the bag proper and passed in parallel relation under the bottom. It has also been the practice to provide a plurality of supporting cords with portions thereof passing under the bottom of the bag proper and interlaced with each other.

For obvious reasons it has been found that it is desirable to provide a bag support ing means which does not penetrate through the bottom of the bag. It is also desirable to use but a single supporting cord and arrange the portions thereof so that the weight of the objects within the bag pressing down upon the bag bottom particularly at the center of the bag bottom, will not have a tendency to break the bottom of the bag or cut through the bottom of the bag in consequence of any sliding movement that the cord may have with respect to the body of the bag.

To this end, the invention resides in the construction, combination, and arrangement of parts, elements and features, hereinafter more particularly pointed out.

In the accompanying drawing:

Figure 1 is a perspective view of thecom- Figure 2 is a perspective view of the cord arrangement used in conjunction with the body of the bag.

The bag is formed from heavy paper and includes side walls 1 and a bottom wall 2. The bottom wall 2 is imperforate. Both of the side walls 1 of the bag are provided with upper spaced openings 3 and lower spaced openings 4. The respective openings at the at openings 3 and 4 are lactate-d at equal distances beyond and at opposite sides of the median vertical dimension of the side walls 1 of the bag.

A single cord '5Vbefore being made endless by a single knot 6, is threaded inwardly through the openings 3 and outwardly through the openings 4 in the lower portion of the sides of the bag. Portions 7 of the said cord extend diagonally from the openings 4 at one side of the bag around the edges and under the lower surface of the bottom 2 .of the bag and through the openings 4 at the opposite side walls 1 of the bag. Thus the portions 7 extend diagonally across the bottom of the bag and intersect or cross each other at the point 8 which occurs at the center of the bottom wall 2 of the bag. Each portion 7 extends from the opening 4 at one side of the median vertical line of one side of the bag to the opening 4 lying at the opposide side of the vertical median line of the opposite side wall 1 of the bag. Portions 9 of the cord extend above the upper edge of the bag to provide handles.

By this arrangement it will be seen that the supporting cord reinforces and braces the bottom of the bag where the greatest strain occurs and the portions 7 may slip or .slide without cutting or damaging the bottom of the bag. At the same time, the sliding movement of the cord through the openings 3 and 4 will accommodate the cord to the folding of thebag, as in packing the bags, and in holding the bottom of the bag in its normal folded position when the bag is not in use. It will also be seen that the paper bottom of the bag will not have to carry the load and be broken by the variety of objects carried in .a bag of this kind in shopping use. In view of the fact that but a single cord is used, a minimum amount of material is employed in the make up of the bag structure as an entirety and inasmuch as but a single knot is made in the cord, time is saved in assembling the parts. At the same time a bag structure is provided which possesses maximum strength and durability. This is due to the reinforced crossing of the portions 7 under the center of the bottom of the bag givin the maximum support at the center of t e bag bottom, where the-re is the greatest Weight and strain. brought his the contents of the Approxiniatch at the point 8 where the portione T of the eord erosn each other a ring 9 is provided and the said portions 7 are threaded through the said ring as best Ahown in l igrnre 1 ol the drawing. 'ihue the portions 1' may have limited longitudinal sliding; movement with relations to each other but the Side ring will hold the point of intersection S at: all times approximately at the c inter ol? the bottom of the bag and therefore it will be impossible for the pertions 7 to swing around the ends 0] the bottom of the hue and become dieplaced with respect to each other and with relations to the bag bottom.

From the foregoing description of the construction of our improved device it will be seen that we have provided a simple, inexpensive and ellieient means for carryingout the objects of the invention and while we have particularly (li.\ ciil')e 'l the elements; best adopted to perform the functions set forth, it is obvious that various changes in form, proportion and in the minor details of construction may he resorted to without departing from the spirit or sacril'ieing; any of the principles of the invention.

llaving thins tltjHt'l'llltll our invention what we claim is:

A paper bag having an inl wrtorate hottoni wall, the side walls ol the bag having. upper and lower openings located at equal distances beyond the median vertical dimension ol the side walls and an endless cord threaded through, the openings in the side walls of the bag and projecting: above the edge oi the hog to form handles, said endless cord being dis ioned exteriorally of the lower portion of the side Walls of the bag and exteriorally ot' the bottom wall, said cord having portions; extending diagonally from the lower openings in the opposite 'side 'alle oil the bag directly and completely across the under surface of the bottom 01'' the ljltl and around the edges thereof and the portions of the cord at the same side at the lit-1;}: converging toward each other from the openings toward the bottom of the bag and a ring; surrrninding the diagonally disponed portions of the cord.

in testimony whereof we aliix our signaitll'tii.
