BAG OR LINING AND METHOD OF PRODUCING THE SAME Filed Jan. 29. 1931 2 Sheets-Sheet 2 INVENTOR Edwin D Greene ATTORNEYS Patented May 16, 1933 .Lrinkled paper gl nings for containers are usually-madeof, a si ngle. piece of crinkled paper that as foldedover; o'na line extending aiirthegeneraldi-rectipn of. the crinkles in the paper .with ;the ,margins;aof, its longitudinal edgesand the edges pfjoneend folded over and sewed--1 In: somev 'cases,.also the longitudinaledge' iportionjs .ofthe. bag blank either beforeaor.after-closing; the end of the bag tube are tucked in.

and while in open condition is inserted in the container. In the case of barrels, kegs and other containers having circular bottoms. it is diflicult to properly lay the unformed bottom end of the lining on the circular bottom 1 w of the container, and even where care is exercised bulky folds are likely to occur at the bottom of the lining which, of course, is objectionable. It has been proposed to form a flat bottom in the bag blanks or linings before shipment to the user but such pre-forming of the bottoms adds materially to the expense of the linings.

One of the objects of the present invention is to provide a bag blank having an unformed bottom end which may be easily and 3 quickly inserted in a barrel or other container having a circular bottom so as to closely fit the container.

\Vith this object in View, one of the features of my invention consists in the provision of a scoring or crease in the bag blank which is so located that upon merely ballooning the bag in the usual manner, the closed 1 end of the lining takes a substantially circular form which upon insertion of the lining in the container uniformly flattens out and closely fits the bottom of the container.

Another object of my invention is to provide a lining of the character indicated of novel and improved construction.

The lining illustrated in the drawings is particularly adapted for barrels, kegs and other containers having circular bottoms. The bag blank as illustrated'in Fig. 1 may be formed in the usual manner by folding a sheet of crinkled paper upon itself and folding over and stitching the longitudinal edges as indicated at 2 and similarly forming a. seam at one end of the folded sheet as indi cated at 4. In the form shown in Fig.1 the bag blank is provided with a scoring or crease on a line 6 parallelwith the seam 4 and spaced a distance fromthe seam corresponding substantially to the radius'of the bottom of the container. The bag blank is also provided with lines ofstitches '8 extending diagonally across the coifners the closed end of the blank fron the cr ases;

Owing to the pliability of the crinkled paper, as the lining is thus opening up, the closed end thereof tends to fiat-ten out from the crease 6, so that when the. bag is ready to be inserted in the container its bottom takes a substantially fiat and circular form, corresponding substantially to the diameter of the container. Also, owing to the lines of stitches 8 the projcct-ing corners tend to fold over as indicated in Figure 2 so that upon placing the bottom of the lining on the bottom of the container the corners readily lay down flat against the container, and thus a substantially uniform fiat bottom is formed in the bottom of the lining which closely tits the bottom of the container.

\Vhile it is preferred to provide the stitches 8 so as to cause the corners to be folded over easily as the lining is inserted in the container, in place of these stitchings thelinings may be creased across the corners, or if desired the corners may be folded over before ballooning the bag. In fact it has been found that even without such provision for folding over of the corners, that the mere provision of the crease 6 assists materially in properly fitting the lining to the container.

In the form shown in Figs. 5 to 10, inclusive, the bag blank is initially formed in a well known manner by tucking in the longitudinal edges 10 thereof before forming the end seam in the bag blank, and the ends of the tucked-in longitudinal portions are stitched in with the end of the bag tube.

In accordance with my invention, a scoring or crease 12, corresponding to the scoring or crease 6, is provided in the bag blank parallel with the end seam of the bag blank and spaced a distance therefrom corresponding substantially to the radius of the bottom of the container.

During the usual inflation of the bag, the end of the bag blank tends to flatten out from the crease 12 until it reaches a substantially flattened condition, and upon insertion in the container it naturally flattens throughout its area on the bottom of the container as indicated in Figs. 7 and 8.

As will be evident to those skilled in the art, my invention permits various modifications without departing from the spirit thereof or the scope of the appended claims.

What I claim is:

1. In a. lining for containers of the class described, comprising a flat bag blank of crinkled paper having one end and its longitudinal edges closed and having its crinkles extending longitudinally of the blank, the

improvement which consists in said blank, having a peripheral crease spaced a distance from the closed end thereof to assist in forming a substantially flat bottom in the lining when the lining is opened, said-crease de fining the outer edge of the bottom thus formed and said bottom being adapted to substantially fit the bottom of the container.

2. A structure according to claim 1 in which the longitudinal edges of the bag blank are tucked in.

3. A structure according to claim 1 in which a' line of stitching extends from said crease diametrically across each of the corners at the closed end of the bag blank.

4. In a lining for a container having a circular bottom of the class described comprising a flat bag blank of crinkled paper having one end and its longitudinal edges closed and having its crinkles extending longitudinally of the blank, the improvement which comprises said blank having a peripheral crease spaced a distance from the closed end thereof corresponding substantially to the radius of the bottom of the container to assist in forming a substantially flat bottom in the lining when the lining is opened, said crease defining the outer edge of the bottom thus formed and said bottom being adapted to substantially fit the bottom of the container.

In testimony whereof, I have signed my name to this specification.

EDWIN D. GREENE.
