PAPER BAG.

SPECIFICATION forming part of Letters Patent No. 355,010. dated December 28, 1886.

Application filed May 12, 1886.

Serial No. 201,956. (No model.)

To CLZZ whom it may concern.-

Be it known that I, HARRY M. FARNS- WORTH, a citizen of the United States, residing at Cleveland, county of Ouyahoga, and

5 State of Ohio, have invented certain new and useful Improvements in Paper Bags, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

1 This invention relates to all classes of paper bags which are provided with what areknown in the art and to the trade as bellows sides.

The bags of this class, although very extensively used, are to some extent objection- 1 able, because of the difficulty of keeping the mouth of the bag fully open during the operation of filling the bag. This difficulty is caused by the tendency which the bellows folds in the sides of the bag have, whenever go they are opened out, to return to their original position, and thus draw the sides of the bag together and contract the mouth.

It is the object of the present invention to overcome this difficulty, and to provide means 2 5 by which the mouth of the bag when once opened will be maintained in a fully or nearly fully opened position.

To that end the invention consists in providing the month end of the bag with oblique o creases, which extend from the corners of the mouth inward and downward to the central lines of the bellows sides, thereby causing triangular portions of the material at the ends of the bellows folds to bend outward as soon as 3 5 those folds are opened out, and thus hold the mouth of the bag distended.

As a full understanding of the invention can be best imparted by an illustration and a detailed description of a bag embodying the in- 0 vention, such description will be given, reference being bad to the accompanying drawings, in which- Figure 1 is a perspective view of a common form of bellowssided bag, showingthe same 5 distended and ready to be filled. i Fig. 2 is a top or plan view slightlyin perspective, showing the mouth of the bag. Figs. 3 and 4 are views similar to Figs. 1 and 2, showing the same bag provided with theimprovement constitnting the present invention; and Figs. 5

l and 6 are side views of the bag, illustrating two ways of making the creases before referred to.

Referring particularly to Figs. 1 and 2, it is to be understood that the bag therein shown is of the form shown and described in Letters Patent No. 123,811. This form of bellowssided' bag is now so common and is so well known as to render a detailed description of its construction unnecessary. It will be ob- 6o served that in these figures, which show the bag in its opened or distended condition, the bellows folds a project inward for some distance between the sides b c of the bag, thus not only contracting the mouth of the .bag lengthwise, but also tending to draw the sides 19 0 together, and thus contracting the mouth widthwise. This partial closing of the bagmouth is caused by the tendency which the lines in the paper, to at once spring back into position between the sides I) 0 as soon as they are released after being opened out. This, as before stated, makes it difficult to keep the mouth of the bag fully open during the operation of filling the bag, which is often a source of annoyance. To overcome this difliculty I provide the month end of the bag with oblique creases 2, which extend from the corners of the bag inward and downward to the cen- 8o tral lines of the bellows folds, as shown in Figs. 3 and 4. These creases 2 are so formed that the triangular portions 4 above them have a tendency to spring outward, as shown, and thereby enlarge the mouth of the bag lengthwise. The portions 4, springing ontward in this manner, also have a tendency to hold the sides I) c of the bag apart, and thus prevent the mouth of the bag from being contracted widthwise. The creases 2 may be formed in any suitablemanner, either by creasing the paper before the bellows folds are formed and allowing the portions 4 to remain in the completed bag in the position shown in Fig. 6, or by folding the portions 1 outward between the sides of the bellows folds, as shown in Fig. 5.

The particular form of bag shown in the present case has been selected merely for the purpose of illustration.

bellows-folds a have, by reason of the creased 7Q The improvement [00 constituting the present invention is equally applicable to all classes of bags having bellows sides.

What I claim is 1. A bellows-sided bag having the creased lines 2, extending from the corners inward and downward to the central lines of the bellows folds, substantially as described.

2. A bellows-sided bag having the triangular portions 4 folded outward on the lines 2, x0 substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
