7 Claims. (Cl. 229- 54) This invention relates to bags, and more particularly to handled sewn multiwall paper bags.

Among the several objects of the invention may be noted the provision in an economical manner of a sewnbag, and particularly a sewn multiwall paper bag, with a handle by means of which the filled bag may be conveniently carried without discomfort to the hand; the provision of such a bag with a handle which is in itself strong and which is firmly attached to the bag so that it will not rupture or tear loose from the bag under a relatively heavy load; the provision of such a bag with a handle which occupies an out-of-the-way position until it is to be used for carrying the bag; and the provision of such a bag with a handle which is attached to the bag as an incident to the formation of the closure of one end of the bag. Other objects and features will be in part apparent and in part pointed out hereinafter.

The invention accordingly comprises the constructions hereinafter described, the scope of the invention being indicated in the following claims.

In the accompanying drawings, in which several of various possible embodiments of the invention are illustrated:

Fig. 1 is a view in elevation of a sewn paper bag provided at the top with a handle of this invention;

Fig. 2 is an enlarged cross section taken on line 2-2 of Fig, l, thicknesses being exaggerated;

Fig. 3 is an enlarged cross section taken on line 3-3 of Fig. 1, thicknesses being exaggerated;

Fig. 4 is a view illustrating the formation of the handle per se; and,

Fig. 5 is a view illustrating a modification.

Corresponding reference characters indicate corresponding parts throughout the several views of the drawmgs.

Referring to the drawings, there is indicated at 1 a paper bag provided with a handle 3 of this invention. The bag would usually be a multiwall paper bag (a plural-ply paper bag), but it will be understood that the handle is applicable to a single-ply paper bag, or to a bag made of material other than paper. One end of the bag (the upper end as shown in Fig. l) is closed by a sewn closure generally designated 5, including a paper tape 7 folded around the end of the bag, a filler cord 9 and a line of stitching 11 driven through the filler cord,

the tape and the bag walls to hold the walls together and to hold the tape in place. Tape 7 may or may not e pasted to the bag walls. The other end of the bag (its lower end as shown in Fig, 1) may be initially left open, being subsequently closed after the bag has been filled as by means of a conventional stitched closure. It is also possible that the bag might be a valve bag, in which case both ends of the bag would be initially closed.

As shown, the stitching 11 comprises a needle thread 13 having loops 15 extending from one side of the bag (which is referred to as the needle side) through the filler cord 9, the tape 7 and the bag walls, and a looper thread 17 on the other side securing the loops 15 from 2,957,618 Patented Oct. 25, 1960 being pulled out. It will be understood that the stitching may be of the conventional chain stitch or lock stitch type. It may be a single-thread type of stitching instead of a two-thread type. The tape 7 projects beyond the sides of the bag, and the stitching 11 extends in a straight line throughoutthe length of the tape.

The handle 3 consists of a strip of narrow woven textile fabric, such as a coarse plain-woven cotton fabric of a type such as is used for drawtapes in drawtape bags (see, for example, Scruggs US. Patent 2,557,517, dated I June l9, 1951). The handle'strip 3 has a length somewhat greater than-the width of the bag, and somewhat greater than the length of the closure tape 7. The width of the material of the handle strip may be approximately two inches, for example. It is bunched or pleated by folding it along longitudinal fold lines as indicated at 19 in Fig, 4. End portions 3a of the'bunched or pleated strip 3;are disposed under the closure tape 7 on one side of the bag(the needle side) and are caught in the stitching. 11. The strip 3 extends from end-to-end of the tape 7 and the ends .of the strip .are coincident with the ends of the tape. As stated, the strip 3 is longer than the tape,:7, and it:has a loose central portion 3b free of the stitching, 11. and located out from under the tape 7 which is adapted to be grasped in the hand for carrying the bag, then assuming a position such as illustrated in dash lines in Fig. 1.

With the bunched or pleated end portions 3a of the strip 3 caught in stitching 11 under tape 7, the strip is securely caught and will not readily tear out from the stitching, even under a relatively heavy load. Also, the bunched or pleated end portions are of substantial breadth so that there is no particular difiiculty in assuring registration thereof with the needle of the sewing machine during the stitching operation, even though the bunched end portions are under the tape 7. The strip itself is strong so that it will not break even under a relatively heavy load. The bunched or pleated central portion 3b which is grasped in the hand is of such character that it does not cut into the fingers, so that the filled bag may be comfortably carried.

Fig. 5 illustrates a modification involving the stitching of the folded handle strip 3 as indicated at 19, the stitching running longitudinally of the handle strip 3 throughout its length. This strengthens the strip. The strip is initally folded along its longitudinal center line as indicated at 21, and the stitching is spaced from the fold and maintains the strip in its folded condition;

If necessary or desirable to strengthen the sewn end of the bag, a reinforcing band such as shown in Williams US. Patent 2,854,186, dated September 30, 1958, may be used.

In view of the above, it will be seen that the several objects of the invention are achieved and other advantageous results attained.

As various changes could be made in the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

I claim:

1. A bag having a closure at one end constituted by a tape folded over the end of the bag and a line of stitching driven through the tape and the bag walls, and a handle at said end of the bag constituted by a strip of material having bunched end portions underlying the tape on one side of the bag and caught by the stitching and having a loose central portion free of the stitching and located out from under the tape and adapted to be ing a reinforcement extending lengthwise thereof.

2. A bag having a closure at one end constituted by a tape folded over the end of'the bag and a line of stitching driven through the tape and the bag'walls, and a handle at said end of the bag constituted by a stripof material extending from end-to-end of the tape with its ends coincident with the ends of the tape, said strip having bunched end portions underlying the end portions of the tape on one side of the bag and caught by the stitching and having a loose central portion free of the stitch ing and located out from under the tape and adapted to be grasped in the hand for carrying the bag.
