IACKAGE AND PROCESS OF MAKING IT.

Application filed July 7, 1921. Serial No. 482,942.

To all whom it may concern:

Be it known that I, ADELMER M. BATES, a citizen of the United States, residing at Chicago, in the county of Cook of Illinois, have invented a certain new and useful Improvement in Packages and Processes of Making Them, of which the following is a specification.

My invention relates to an improved package, and a process for forming it, and particularly to packages adapted for holding material such as flour, rice and the like, and particularly also to packages made of paper or similar material. The package in general terms comprises a tube of paper closed at each end by a reinforced seam, the length of the bag closing portion of the seam being substantially equal to the diameter of the filled bag or package in the direction of the seam and less than the width of the tube when collapsed without inward folds. The side walls of the package adjacent the seams are inwardly folded to reinforce and shorten the seams. The package illustrated is made of crinkled paper which will expand something like 30 per cent of its tearing.

My invention is illustrated more or less diagrammatically in the accompanying drawings, wherein Figure 1 1s a side elevation of the-package;

Fig. 2 is an end elevation;

Fig. 3 is a plan view of the package,

Fig. 4 is a section through the end of the tube at the place where the seam is to be formed, and

Fig. 5 is a diagrammatic view of a means for forming the packa e from a tube.

A is a tube of crink ed paper, though of course it might be of cloth or membraneous material, or even of smooth; tough paper. A is a pasted longitudinal seam, although this might be a sewn seam. If it were sewn, the seam would probably be inside, the tube A A are the inwardl bent ends of the tube forming the ends 0 the package and joined together by the seam A.

The seam A is made up of the two parallel reinforcing members B B, which members are sewn together by stitches B B and State length before I opposed sides of the bag an of thread or the like extending throughthe reinforcing members and through the package material to form a reinforced seam.

C G are inwardly bent portions of the tube j between the portions A A and these inwardly bent portions terminate in accordion folds 0 G which are sewn into the seam ..so that the corners of the bag at the ends of the seam are reinforced as at C there being at this point four thicknesses of the paper or other fabric instead of two, and these four thicknesses being also reinforced by the reinforcing members. corners of the package at the ends of the seam, which are the points likelyto support the heaviest load and likely tobe the weakest parts of the bag, are reinforced both by the folding of the bag and by the presence of the reinforcing members tied together by the holding seam. As will be noted, the inwardly bent portions G form a hand hold of advantage in handling the bag and the reinforced seam may be gripped ,readily without tearing the bag.

The process of forming the package from a tube may be made easier by a prefolding of the tube before the charge of material is placed therein; In such a case the tube, is folded or collapsed, as'illustrated in Fig. .4, the accordion pleats therein, running from end to end of the tube when in collapsed condition. In the, process illustrated, an elongated tube, thus prefolded, is fed forward about any preferred bag-filling means, such as a filling tube D, and the tube is collapsed longitudinally thereabout. The bottom closure is'then formed by puckering or pleating the bottom of the tube as above described, the tube being sewed across to form the type of seam and reinforced bag end illustrated in Figs. 2 and 3. Acharge tion of the bag section by folding the has inwardly at opposed points on the prefor of the tube. The are thus collapsed, the operator then passes the collapsed portion of the bag through any means E adapted to sew the reinforced seam above described. The section thus formed is then severed from the tubing along line parallel folded or creased portion Thus the four lettered C closures are made its a packs? and one method of making the same, regard as essential only those features stated in the several appended claims. I have shown a particularclosure applied to a filled package, but the I have described in some detail a in orcing members on each'side, but in some instances reinforcing elements may be dispensed with or used on one side only, and numerous other changes may be'made in the article and process within the scope of the appended claims without departing om the spirit of the invention.

I claim- 1. As an article of manufacture, a age comprising; body portion,an en sure formed by a seam substantially equal in lenlglth to the width of the body portion when led, the walls of the body portion being folded vin-adjacent the closure to form a reentrant pocket at each end of .the seam and the seam being formed by sewin v through the walls, including thein'folde portions.

2. As an article of manufacture, .a bag comprising a body portion, a stitched closure and a reinforcing element extending entirely across the closure and held in place solely by the stitches of the closure, the walls of the body portion being folded in adjacent the closure ,to' form a reentrant pocket, at each and of the seam gdflthe saeialgn formfid ysewingthro ew ,incuin te infolded portion g 3. As an article of manufacture, a. package comprising a tubular bag body cut oil acres each end and closed by seams, the tube wallwbeing folded in to form a reentrant pocket at eachend of each seam and the seam being formed by sewing through the walls, including the infolded portions.

4. an article of manufacture, a package comprising a tubular acres each end and closed bag body cut off by seams, a reinforcing element across each end closure and held in place thereon solely by the stitches of the seam, the tube wall be' folded in to form a. reentrant pocket at each end of each seam and the seam being formed by sewing through the walls, including the infolded portions.

5. As an article of manufacture, a bag comprising a tubular bag y cut oif across of crinkled end, a reinforcing element across age consisting of an end and closed by a seam, a reinforcing element extending entirely across said clo- As an article of manufacture, a bag I having an end folded inwardly on two opposite sides and closed: by through the sides and folds, the apex of .each fold extending through the seam.

8. As an article of manufacture, a bag comprising atubular bag body, a stitched closure across an end of the body and a reinforcing element sure on each side of the bag and held in position solely by the stitches of the closure, the walls of the bag body being folded in at each end of the closure and the stitches passifngd through the walls at the apex of each 9.
