Application September 17, 1937, Serial No. 164,376

12 Claims.

My invention relates to carrying bags of paper and similar material which are provided with cord handles; such bags being familiarly known as shoppers. My invention comprises a special type of handle structure; the manner or method of attaching the same to a bag of paper or similar material, and the complete bag furnished with such handle structure.

In my Patent No. 2,075,672, dated March 30, 1937, I have described and claimed the manner of and one form of mechanism for making a type of cord handle structure which includes a loop of cord permanently secured to a strip of cardboard or like material which is employed as the means of the type indicated. My present invention relates to a handle structure' of the type shown in my prior patent; the manner or method of applying such handle structures to bags of the shopper type, and to the completed bags equipped with such handles.

One object of my present invention is to facilitate the attachment of these handle structures to bags of paper and similar material by enclosing or covering the handle-attached cardboard strips within folded vends of the bag walls which are adhesively held to such strips. l And a further object of my invention is to utilize the position of the cord loops with respect to the ends of the strips and the staples or other fastening means holding such looped cord handles to the cardboard strips as the means for effecting proper placement of the handle structures with respect to folded portions of the walls of the bag at the open end of the same.

These and other features of my invention are more fully described hereinafter; reference being had to the accompanying drawings, more or less diagrammatic in character, in which: 40 Figure l is a fragmentary perspective view illustrating one end of a bag of the shopper type, to which my improved handle structures are to be applied.

Fig. 8 is an enlarged sectional view, fragmentary in character, illustrating a detail of my invention. I

In Figure l, I have shown the open end of a 10 bag, indicated at l, in a. relatively distended condition, with the opposite walls i* provided with notches 2 disposed in registering relation and having ilap portions 3 between the same.

The lines a., a, indicate `creases preliminarily formed in the walls adjacent to the open end of the baga short distance beyond the termination of the notches to deilne the portions of the ends of the bag walls which will be turned in after the handle structures have been applied thereto and rmly fastened against the strip portions of such handle structures, to which adhesivefhas been previously applied. For convenience and to facilitate the operation of separating or distending the bag walls for application of the handie structures, one of the naps 3 lying between the notches 2 may be slightly shorter than the other, as indicated at 3a in Figs. l and 4, though the shortening of the flap is not essential n carrying out my invention. f

The handle structure, of the type illustrated in my prior patent before referred to, comprises a strip of heavy paper, cardboard, or like material, indicated at Ill, carrying a looped cord, indicated at Il, which has been secured thereto by staples I2, or otherwise; such fastening means being placed centrally through the cord, lengthwise of the same when staples are used, and disposed substantially centrally of the side edges of the strip.

In addition, the straight runs of the looped cord, indicated at I la, are denitely spaced on the strip in positions equidistant from the ends of the same, with such straight runs the same distance apart on each successive strip so as to exactly register with the preformedpnotches formed in the ends of the bag Walls. When staples are employed as the means for fastening the cord loops to the cardboard strips, each leg passes through the cord-preferably centrally of the same-as indicated in Fig. 8. While it is not essential that the cord-fastening means-staples or other devices-shall occupy a central position with respect to the side edges of the strip, although such position has its advantages, it is desirable that the yfastening means, of whatever nature may be employed, shall occupy the same position vin each strip so as to facilitate application to the bag by drawing such fastening device against the lend of each notch, in thev manner indicated in Figs. 4 and 6. Figs. 2 and 3 illustrate clearly that the cord loops are placed centrally of the strips and that the straight runs areequidistant from the ends of such strips. The surface of the strip upon which the cord lies has had adhesive applied thereto over the area indicated at b, in Fig. 2; a portion of such strip indicated at :c having been left blank, while the opposite side of the strip has had adhesive applied over its entire area, as indicated at b', Fig. 3.

By reason of the fact that at leastone of the flaps 3, (indicated at 3) between the notches 2 at the ends of the bag walls may be shorter than the other, thearea of the adhesively covered surface between the cord sections stops short of the lower edge of the strip, as indicated at z, Fig. 2, so that when such shorter flap is finally secured in position over such strip there will be no uncovered adhesive. 'I'he opposite full length flap will overlie the uncovered portion of' the strip of the other handle structure.

In associating my improved handle structures with respect to the bags to which they are to be attached, said bags are presented to the operator who opens the end of the same to the position indicated in Fig. 1; such bag walls having been creased along the lines a, a, and provided with the notches 2. The notches terminate short of the creases a, and the distance between the ends of such notches and the bag folds or creases a may be substantially equal to the space which exists between one leg of the staple or other fastening means holding the looped cord to, the strip, and an edge of the latter, Aas clearlyindicated in Fig. 6. In whatever relation the fastening elements are placed, they are uniform in all oi' the handle structures by reason of the fact that such fastening means are applied by'mechanical means in exact relation to the side edges of the strips, and when the strips are associated with the ends of the bags, the fastening means are brought into engagement with the ends of the notches. As the latter are of uniform depth and in uniform spaced relation, the uniformly spaced straight runs oi' the handle loops insure that the handle structures will be uniformly and properly applied to the successive bags.

' To the notched and creased ends of the bag a pair of handle structures are applied; such handle structures being of the' type illustrated in Figs. 2 and 3, and disclosed in my patentbefore rei'erred to; both surfaces of the strip portions of such handle structures having been coated with a suitable adhesive, as indicated 'Ihe adhesive is wet and ready for application to the bag walls and the handle structures will be presented to the operator in such position that a handle structure maybe picked up in each hand and with the handle loop of each one outwardly disposed so that they may be applied to the end walls of the bag; the strip portions entering the bag and the handle loops lying outside the same opposite the notches and being drawn against the edge of the bag wall so that the fastening devices for the handle loops engage the ends of 'the notches, as clearly indicated in Fig. 6.

With` the open ends of the bags presented in position by the operator (and this might conveniently be done by placing a group of bags between the knees) the ends of the bag walls are separated by grasping the longer ilap, and then that the upper edge of such strips shall engage the fold, as clearly indicated at y, Fig. 7.

It will be understood that both handle structures are applied simultaneously, and the next operation will be to fold in the ends of the bag walls at the creased portions of the same, with said strips in engagement with such portions, and then to turn these ends in so as to bring the other surface of the strips against the inner surface of the bag walls below the creased portions, the portions beyond the creases inside the bags overlying the strips, and after this operationthese infolded ends may be pressed together to insure proper contact of the bag walls with the adhesively covered strips to present the bag in the finally handled condition.

While reference is made in the foregoing description to the manner of applying the handle structures and, as illustrated in Figs. 4 and 5, that application of the handle structures is made vprior to folding or turning in the ends of the bag walls, it will be understood that these ends may be folded in before the handle structures are applied, in which case the operator introduces the strip portions of the handle structures into the open end of the bag with the handleloops uppermost and with the straight portions ofl the same in such position as to enter the preformed notches 2 and then draws the strips into their flnal position beneath the turned-in portions of the bag walls, after which these turnedin portions are pressed against the strips, adhesivly connecting them with the inner surfaces of the walls of the bag on the one side and with the turned-in portions of the bag walls beyond the creases, on the other side.

An important feature of my inventionresldes in the fact that in the handle structures as prel formed before application to a bag, the cordfastening means, preferably in the form of twopronged elements such as staples, have both legs passing through the centre of the cord runs and are clinched against the opposite side of the strip. Even though other forms offastening means may be used to secure the handle loops to the strips, such fastening means pass through the central portion of the cord. While I prefer to have the fastening means for the cord loops centrally of the strips with respect to the side edges of the same, such position may be varied so long as it is the same with each handle structure. This conditionis readily brought about by reason of the fact that inthe formation of the handle structures the cord will be exactly positioned across the same and the fastening means will be applied in the same position with respect to each strip, uniformly. u

It will be understood, of course, that while I have disclosed specific embodiments of my invention, I do not wish to be limited thereto and 1.
