PAPER BAG.

Specification of Letters Patent.

Patented Apr. 26, 1910.

To all whom 'it may concern:

Be it known that I, HENRY W. STUART, a citizen of the United States, residing at Fernbank, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Paper Bags, of which the following is a specification.

My invention relates to an improvement in paper bags of the duplex type in which the innermember consists of paraffin pa er or other moisture-proof suitable materia The objects of the invention are to simplify and cheapen the product and at the same time to improve and strengthen the bag structurally.

TheV features of the invention are more fully set forth in the description of the accompanying drawings, forming a part of this specification, in which Figure 1 is a plan view of the outer blank. Fig. 2 is a plan view of the inner member, partly formed. Fig. 3 is a plan view showmg the relative positions of the inner member'and the outer blank and method of applyln glue for sealing the bottom. Fig. 4 1s a p an view of the com leted article with a portion of the outer b ank thrown back. Fig. 5 is a cross section through the bottom of the double bag, showing the formation at this point. Fig. 6 is a View similar to Fig. 3, showing a modification. Fig. 7 is a section through the bottom of the modification of Fig. 6.

This bag is formed of an outer member consisting of a blank folded u on itself to form a bottom along the line o folding, the meeting side edges of the folded sections being secured together in any suitable manner; and an inner member consisting of a strip of paper or a blank folded upon itself in lines transverse to the line of folding of the outer member, so that the inner bag has two folding lines corresponding in osition to the side seams of the outer bag, w ile the meeting ends of the inner blank are secured together upon a line adjacent to an inter- Thus it will be seen that the" lateral or si e seams of the outer and the inner bag are parallel, but the seams of the outer bag are adjacent to an integral portion of the inner ba and the single seam of the inner bag is a jacent to an integral portion of the outer bag. This is to prevent the bag from having comcident seams along the sides. The outer blank consists of a side l, havin laterally extended flaps 2, constituting olding and gluing ed es, and the opposin side 3 forming an en wise extension of t e side 1 and separated by the intermediate foldingl line 4. The

sides

1 and 3 are of the same dimensions so that when the piece 3 is folded upon the piece 1, the flaps 2 ma be folded over and secured tothe mar ina side surfaces of the piece 3, as indicate in Fig. 4.

T e inner member 10 which is of suitable moisture-proof material, consists of a strip of paper, the

opposite ends

6, 7, of which, are folded inwardly and brought together substantially along the medial llongitudinal line of the receptacle to be formed; they are overla ped and secured by the glue 4, indicated 1n Fig. 2. Preferably, this inner member has at one end, an extended flap 5 adapted to be folded over the sections 6 7, of the inner member 10, see Figs. 2 and 5. If desired however, the flap 5 may be omitted, as indicated in Figs. 6 and 7, in which case the inner member is bottomless, the bottom being formed by the folding over of the outer bag member 3, see Fig. 6, a marginal stri of glue 7a being applied to the member 3 a jacent the open end 8 of the inner member, so as to secure the outer member to the inner member at this point, and thus form a bottom for the inner member, the relative positions being indicated by Figs. 6 and 7.

Preferably, however, the bag is constructed as shown in Fig. 3. It will be understood that the innei member is of the same dimensions as the member l and is laid thereon in position to be infolded by the end extension 3 and the gluing fiaps 2, with the flap 5 extending beyond the folding line 4 of the outer member and lying upon the adjacentportion of the member 3. The glue 9 is then applied to the flap 5 and extending slightly beyond, covers a narrow section at the folding end of the member 3. When the member is folded over on the member 1, the flap 5 is folded over and adhesively secured upon the outer surface of the

parts

6, 7, of the inner bag, and also the glued section 9, of the part 3, is adhesively secured upon the

parts

6, 7, just above the line of attachment of fla 5. Finally the flaps 2 of the art 1, are fo ded over and adhesively secure u on the inner marginal edges of the outer ag member 3. These bags are substantially fiat when collapsed so as to be shipped knockeddown, and they may be opened up and filled with tobacco or other similar commodities which can be economically handled in packages of this character. In a bag thus formed, the seams of the outer bag are at the outer marginal edges, and the single side seam of the inner bag is at an intermediate point. This strengthens the article structurally, for the reason, that when the bag is opened up, the sides of the two members are not. secured together coincidentally. Of course, this line of adhesive attachment is the part most likely to tear under the strain of opening, and with this construction, if the outer member starts to tear along the lines of attachment of the flap 2, theadjacent portion of the inner member being integral along this line, will not be apt to tear, the one serving to reinforce the other.

Having described my inventien, I claim l. A bag formed of two blanks placed together for folding, the outer member consisting of a blank folded upon itself to form a bottom along the lines of folding, the meeting side edges of the blankV being secured together, and the inner member consisting of a blank folded upon itself transversely to the line of folding of the outer blank, the meeting ends of the inner member being secured together adjacent an integral section of the outer member, and the meeting edges of the outer member being secured together adjacent the integral sections of the inner member, substantially as described.

2. A bag formed of two blanks placed together for folding, the outer member consisting of a blank folded upon itself to form a bottom along the lines of folding, one of the folding sections lhaving gluing flaps eX- tending laterally beyond the adjacent edges of the opposing sections, and the inner member consisting of a blank folded upon itself transversely to the line of folding of the outer blank, the meeting edges of the inner member being secured together Ito form a lateral seam adjacent an integral section of the outer member, and the gluing flaps of the outer member being secured 'to the opposing section of the outer member to form lateral seams adjacent integral sections of the inner member, substantially as described.

3. A paper bag consisting of two blanks placed together, the outer blank being folded upon itself to form a bottom along the line of folding, the inner blank being folded. upon itself and having its meeting edges secured together on a hne transverse to the folding line of the outer blank, the inner bag being placed, within the outer bag,

means adhesively securing together said bags at the bottom, and means Securing tofA to the folding line of the outer member, said flap being secured upon one side of the inner member to form a bottom therefor, substantially as described.

5. A double paper bag composed of two blanks placed together for folding, the outer member consisting of a blank folded upon itself to form a bottom along the line of folding and constituting the outer bag, the inner bag consisting of a blank folded upon itself and having its meeting edges secured together, the folding lines of the two blanks being substantially at right angles to one another, substantially as described.

6. A doubleI paper bag consisting of two blanks placed together for folding in one continuous operation, the outer blank being folded upon itself to form a bottom along the line of folding and constituting the outer bag, the inner bag consisting of a blank,

folded upon itself and having each end open, and having its side meetin together, the folding lines o the two blanks being substantially at right angles to one another, substantially as described.

7. A flat paper bag formed from an outer blank of suitable paper material, and a lining blank of waxed paper, the outer blank comprising abroad side and a narrow side with a. middle line of fold, and with longitudinal score-lines for the broad side to form narrow securing flaps, the inner linin blank having transverse and longitudina score-lines to coincide with the corresponding score-lines of the outer blank, and having wide securing side flaps to overlap when the bag isfolded and a narrow locking stripV to lock around the lower edge ofthe narrow flaps of the outer blank when folded.

In' testimony whereof, I have hereunto set my hand.
