BAG AND CLOSURE THEREFOR Application filed June 80,

The invention relates to new and useful improvements in bags and more particularly to the closure for the bag.

An object of the invention is to provide a bag which is closed by stitches passing through a strip folded about the edges of the side walls of the bag at the mouth thereof with means located between the strip and the side walls of the bag for preventing ma terial from escaping from the bag through the needle punctures in the side walls of the g further object of the invention is to provide a bag enclosure of the above type wherein the means which closes the needle punctures is of a character to permit air to filter therethrough.

A further object of the invention is to provide a bag enclosure of the above type wherein the means which closes the needle punctures is in the form of fabric strips which also reinforce the walls of the bag and aid in the firm anchoring of the stitches.

These and other objects will in part be ob vious and-will in part be hereinafter more fully disclosed.

In the drawings which show by way of illustration one embodiment of the invention Fig. 1 is a side view of a bag embodying the improvements.

Fig. 2 is a sectional view on the line 22 of Flg. 1.

Fi 3 is a view of the opposite side of the bag om that shown in Fig. 1.

The invention is directed to a sure therefor which is particularly useful where the bags are made of paper or like material. Prior to the invention it has been customary to enclose the edges of the bag at the mouth thereof with a strip which is laced along the outer face of one wall of the ag, folded over the edges of the walls and against the other wall of the bag, and then the bag is closed by a line of stitches passing through the strip and the walls of the bag. In a closure of this type the needle makes a puncture through the side walls of the bag which remains more or less open, particularly if the bag is made of paper or the like.

These abric strips 3 and 3' ric of soft textu are made of closely woven re. The strips are so placed that the line of closing stitches which is indicated at 4 passes through the closing strip and these fabric strips 3 and 3. st1tches preferably include a which is formed The closing needle thread into loops by a needle which punctures the closing strip and the side walls of the bag and also the strips 3 an d 3'. The

needle thread loops are secured by loops formed in the looper thread. Other types of stitches may be used in the closing of the bagmouth. The ent closure essential feature of the presis the fabric strips 3 and 3 located inside of the closing or binding strip 2, so as to be concealed thereby and so as to be against tne side walls of the firmly clamped ha g by the stitch held es. The fabric of these strips will contract when the needle is Withdrawn about the needle thread and thus effectively close the needle punctures so as to prevent the escape of material therefrom. Air in the bag may, at the same time, filter through the strip. The strip also serves as a means for reinforcing the closure as; the stitches pass therethrough and aids in the firm anchoring of the stitches and prevents the same from pulling through the closing strip 2 and the side walls of the bag. By the arrangement of the strips there has been provided a very firm closure for the bag and one which efi'eo tii'ely closes the bag so as to prevent the escape of any fine material in the bag. It will he understood, of course, that the bag may be made of other material than paper and that the strips would be of advantage.

It is obvious that minor changes in the shaping and the arrangement of the parts may be made without departing from the spirit of the invention as set forth in the appended claim.

Having fully described my invention, what I claim as new and desire to secure by Let ters Patent, is

A bag having side walls, a=cl"0sing strip folded about the edge portions of the side walls at the mouth of the bag, 'a strip of fabric of soft texture disposed bet-Ween the closing strip and the side wall of-"the bag at each side thereof, a lineof stitches passing through the closing strip, thestri'ps of fabric of soft texture and the side waljlsiof the bag for closing the bag and holding the closing strip firmly in contact with the strips of fab ric of soft textnre,wh ereby said fabric strips of soft texture will contract at the needle punctures and 't'lose in' againstthe needle thread for substantially the needle punctures and preventing the escape of the material from the bag ther'ethrough.

In testimony whereof, I afiix my signature.
