OF ST. PAUL, MINNESOTA BAG AND METHOD OF MAKING THE SAME Application filed February My invention relates to bags which are made upon a machine from sheet material or rolls of paper and which are adapted to provide a bag for various uses ofa strong substantial nature adapted to resist wear and provide a means of carrying and supporting goods within the same in the most efficient manner, yet having an economical nature so that the bags can be marketed at a reasonable price.

A feature of the invention resides in applying reinforcing means to the material which makes the bag as the material passes through the bag machine so that when the material is discharged from the bag machine the finished bag is ready for use having reinforcing means extended along the sideof the same to strengthen the bag.

My invention further includes a: bag wherein the same may be used for a shopping container so that the bag is provided with suitable carrying handles to permit the goods within the bag to be readily carried, the body of the bag having suflicient strength to provide a tough and wear resisting material most adaptable for bags of this nature.

My invention includes reinforcing means which is adapted to be applied to the body of the bag as the same is made up in a manner so that the reinforcing means is virtually a part of the same and so that the reinforcing means can be folded into engagement with the bottom of the bag as it is made, thereby overlapping the reinforcing means in the bottom to provide a strong bottom portion to the bag. This is an-essential feature of the invention as it permits reinforcing means to be made a part of the bag body.

The reinforcing means is inter-folded with the portions forming the bottom, thereby strengthening-the bottom and side walls of the bag. This-construction extends the reinforcing means the length of the bag so that carrying handles can be attached at the mouth at the bag in a manner so that the reinforcing means assist to directly carry the load. i. a I

My reinforced bag is also adapted to the type of shopping bag wherecord' means is extended through the walls of the bag and 18, 1926. Serial No. 89,085.

over the bottom of the same and adapted to form gripping handles at the top. In this construction the cords are threaded directly through and over the reinforcing means forming a part of. the bag, thereby providing a strong wear resisting shopping bag with supporting handles at the top and portions extending over the reinforclng and across the bottom of the bag.

My method of manufacturing my bag includes means adapted to apply reinforcing material to the material making up the body of the bag as material passes through the bag machine automatically and continuously so that the reinforcing material becomes an inherent part of the finished bag extending from end to end and being adapted to be folded in at the bottom with the folding of the bag so that the reinforcing means provides means for supporting the load over the bottom of the bag directly up to the neck or opening of the same.

My bag structure permits the making of a shopping bag which is provided with handles at the top, the reinforcing means extending from the top and the handles over the sides and across the bottom, thereby permitting a shopping bag to be made which can be readily carried by one handle if it is desired to support the load within the same without danger of breaking the bag under ordinary use. This is accomplished by the reinforcing means which extends from the top over the sides of thetbag and across the bottom so that when the handles are attached at a point adjacent to or through the reinforcing means at the top ofthe bag, the strain of the load in the bag is directed to a largeextent from the reinforcing means over the bottom and up the sides direotl to the supporting handles of the shopping ag.

These features, together with other objects and detailsof construction and means of carrying out my method will be more fully and particularly pointed out in the following specification-and claims.

Figure 14 illustrates a stage of the manufacture of my bag, only a part of the bag being illustrated.

Figure 15 illustrates another stage of the manufacture of my bag, only a part of the bag being illustrated.

igure 16 illustrates another stage of the manufacture of my bag, only a part of the bag being illustrated.

Figure 17 illustrates a portion of my bag, a part of which is broken awa In the drawings my bag A 1s designed to be made of paper or any other suitable material having the body portion thereof formed with side walls 10 and 11 which are adapted to fold flat against each other in a manner to provide a bag which when folded is adapted to lie in a flat state.

The bottom 12 of my bag A is designedto fold flat against either side wall of the bag as illustrated in Figure 16 when the bag is folded. Inopen position the bottom 12 is adapted to extend straight across in approximately a rectangular shape, however, this is merely a means of illustrating the formation of my bag when complete and it is obvious that the bag may be of any suitable design and nature having a construction which is adaptable to be made up on an automatic bag machine, adapted to make a square or satchel bottom bag.

The method of carrying out the making of my bag consists in employing sheet material such as 14 and applying thereto reinforcing strips 15 extending along longitudinally of the material 14 and being attached to the material 14 automatically as the material is passed through an automatic bag making machine which is adapted to fold the material 14 to provide the sides 10 and 11 with the overlapping edges 16, thereby providing a tubular body portion as is illustrated in Figures 11, 12 and 13. This forms the bag A with the side walls 10 and 11 adapted to fold fiat against each other and edges the reinforcing means 15 in a manner to extend along the sides and from end to end of the bag A.

As the ba forming material 14 passes through the ag machine the same being of ordinary Well known construction and not illustrated in the drawings, the material is folded as illustrated in Figures 11, 12 and 13 with the overlapping edges 16. In the progress of the material 14 through the bag machine my bag A is designed to be scored along the dotted lines 18 and slit at 19 so as to form a satchel bottom type of bag in one construction of my bag A. As the material 14 passes through the bag machine the strips 15 are automatlcally attached thereto and at timed intervals the material is cut off along the lines 20 and 21 to form the ends of the bag as illustrated in Figure 13. After the scoring 18 and slitting 19 of the bag A the same is adapted to be folded with the portions 22 projecting inwardly from the edge 21 as illustrated in Figure 14 which shows the first step of folding in the formation of the bottom 12 of the bag A.

The next step of operation in the folding of the bag A is illustrated in Figure 15 which shows one end 23 pasted against the inwardly folded sides 22 and the other end 24 projecting outwardly from the portions 22 .just before the folding of the same. The next operation is illustrated in Figure 16 which shows the end 24 folded over 'onto the end of the portion 23 and asted thereto to complete the folding and ormation of the bottom 12 by folding the ends 23 and 24 over the inwardly folded portions 22.

In the process of the making of the bag ,A, strips 15 are attached to the sheet material 14 and when the material 14 is cut off along the edges 20 and 21 the reinforcing strips 15 are also cut at the same time to provide the bag, as illustrated in Figure 13, with the strips 15 secured to the same in a manner to become a practical inherent part of the bag A. As the bottom 12 is formed by folding the sides 22 and the ends 23 and 24 together, as illustrated in Figures 14 to 16 inclusive, the reinforcing strips 15 are inter-folded in the bottom and to virtually extend over the bottom to form a reinforcing means extending from the upper edge of the bag alon the sides and over and across the bottom 0 the same as is illustrated in Figure 1 with the reinforcing strips extending in line from the edge 21 to form a reinforcing along the sides and over the bottom of the bag which are adapted to materially strengthen the same.

After the bag has been made up in this manner an additional reinforcing means may be applied to the bottom 12 of the same by pasting a strip of material such as 26 across the bottom over the end of the reinforcing strips 15 on the end 24. This reinforcing member 26 merely. forms an additional means of strengthening the bottom of the bag A and is not necessarily an essential detail of the same, however, in some constructions of bags it may be more practical to apply this reinforcing strength so as to strengthen the bottom of the bag and to assist in sealing the overlapping ends 23 and 24 together with the ends of the strips 15 virtually together at the bottom of the same. In Figure 16 the strip 26 is illustrated in dotted outline to show the relative position of the same .over the bottom when the bottom 12 is folded flat against either side of the walls 10 or 11 of the bag.

My bag A may be used as a container for articles of considerable weight and where the bag should be reinforced so as to support the material within the same without danger of the bag breaking and permitting a strengthening of the bag along the side and over the bottom of the same. In this use I have illustrated the bag as shown. in Figure 2 where no handle supporting means are used at the top, but the bag is tied closed at the neck 28 by any suitable securing means. It

i is quite apparent that ordinary paper bags may be made very economically with my reinforcing strips to carry ordinary staple articles of merchandise or groceries in and used by simply drawing the neck 28 together without securing the same with string as is often done by customers in stores. It is also apparent that my bag strengthened in this manner, which is accomplished on a bag machine and all of which is applied and carried out automatically, provides a bag in an economical manner yet having reinforcing means suflicient to prevent tearing away of the bag at the neck while a person is carrying it filled with merchandise. This form of bag makes an improved and inexpensive container for the holding of heavy articles such as flour, sugar, cement, potatoes and any other staple articles which are constantly being packed and distributed in bags.

Adapting my bag to the shopping bag or carrying bag type, the upper edge 20 is adapted to be folded in along the scored line 29 so as to form an inturned marginal edge 30 beneath which reinforcing cardboard strips or the ed e 30 so that when the strips 31 are inserted eneath the inturned edge of the bag, handles 32 may be attached through the slots 33 in the strip 31 and through the openings 34 which are formed or punched. in the strips after they have been placed under the inturned edge of the bag A and so as to form openings 35 through the upper edge of the bag A and directly through the reinforcing strlps 15. In this manner the handles 32 are adapted to extend through the bag and the reinforcing strips so that when the handles are engaged the load carried in the bag is inclined to be along from the handles through the strips 15 and the walls of the bag. Therefore, it is readily apparent that with my reinforced construction of bag the strips 15 will strengthen the sides and bottom of the bag in a manner so as to cause the strain of the load carried by the handles 32 to be carried to a great extent by the strips 15 from and across the bottom up the side walls to the handles. The reinforcing strips 15 strengthen the bag at the openings 35 through the wall of the same so as to obviate the necessity of eyelets or other strengthening means where the hole passes through the bag for the handles.

In the manufacture of my bag by applying reinforcingv strips 15, which is accomplished at the same time that the bag is automatically being formed, is a more economical and better method of strengthening the bag in place of stitching or using eyelets, which is an expensive method.

The handles 32 may hold against the strips 31 in a manner so that the strain of the load is directed beneath the inturned marginal edge 30, thereby further directing the strain against the reinforcing strips 15. In this manner 'my bag A is very adaptable as a shopping bag providin an economical means of carrying merchandise and staple articles and providing a bag which has considerable carrying strength, in fact can be readily carried if it is desired by one handle while the bag is being filled.

In adapting my bag to a shopping bag having a cord carrying handle means, which I have illustrated in Figure 5, the cord 36 1s adapted to pass through the openings 35 at the top of the bag A and extends along inside the wall of the bag and out through the openings 37 then along the strips 17 and over these strips across the bottom and up the other side of the bag in through the openings 37 and up to and out of the openings 35 to form the handle 38. The cord 36 may be one continuous cord looped at the top to form the handles 38 on either side of the bag, or several cords may be used, one on either side of the bag and connected together, but it is essential that these cords extend through the openings 35 and 37 which are reinforced by the strips 15 and the strain of the portion of the cords 36 which extends over the bottom 12 is directed against and along the strips 15, thereby strengthening the bag Where the cord comes in contact with the walls of the same in carrying the load. By adapting my reinforced bag to a carrying bag of this nature with the cords extended over the strips, I provide a very strong construction which is adapted to carry heavy loads and has a considerable wear-resisting quality as the friction of the cords through the openings in the sides of the bag is reinforced by the members 15 and the strips 15 attached to the bag proper form double thicknesses of material where the cords pass through the walls of the bag so as to obviate the necessity of any other reinforcing means in these points. This reinforced construction also provides double thickness of material at points where strain is directed against the cords in supporting the load in the bag along the sides and over the bottom of the bag, thereby providing a bag of a more economical nature to manufacture, yet having all of the advantages of a bag where the openings 35 and 37 have to be strengthened with eyelets or other reinforcing means in these points and points where the strain is directed against the cord.

Obviously the reinforcing strips 15 can be of paper or textile material such as tape or any other suitable strengthening and reinforcing means which can be made a part of the bag A in the most economical manner in the course of construction and manufacture of the bag. sirable that this strip be of a cloth or textile nature in combination with a paper-bodied bag or where the bag is made of any other suitable material and desired to be used for various purposes. However, where the bags A are made of paper it is clearly evident that paper strips may be used having a tough, strong nature which would be amply suflicient to reinforce the body of the bag A for various purposes, thus providing a bag with the de-' sired reinforcing along the sides and over the bottom and into the neckof the bag so that it will properly carry the load for which it is adapted without danger of breaking away and in a manner to provide a bag of an economical manufacture, yet having more strength and utility.

It may be more desirable in some forms of my bag A to provide areinforcing material along the side in a single band or strip such as 40, illustrated in the bag in Figure 3. In this construction the reinforcing strip 40 There are times when it is de-' provides the same function as the reinforcing strips 15 and is in the form of a single strip extending along either side and over the bottom of the bag, thereby providing a band of reinforcing along the bottom and over the sides which is applied at the time of the formation of the bag A through the bag form'- ing machine.

The features and particular construction of my reinforced bag A have been pointed out in a manner to set forth the utility of this reinforced construction of bag and while I have illustrated a particular formation and construction in the drawings I desire to have it understood that the same are only suggestive of a means of carrying out my invention and that the bag and reinforcing may be applied and made a part of the bags in any suitable manner and also applied by methods and to uses other than those above set forth within the scope of the following claims.
