MANUFACTURE OF PAPER BAGS 0R RECEPTACLES.

.Specification of Letters Patent.

Patented Oct. 12, 1920.

' Application filed October 15, 1917. Serial No. 196,603.

T 0 all whom it may concern Be it known that I, CHARLES S. PEASE, a citizen of the United States, residing in Philadel hia, county of Philadelphia, and State of ennsylvanla, have invented certain new and useful Improvements in the Mannfacture of Paper ags or Receptacles, whereof the following is a specification, ref

1 erencebeing had to the accompanying drawin s.

ily invention relates to a bag or receptacle constructed along with its handle wholly of paper and preferably made by the cutting, folding and pasting of a single sheet. There are two handles at the mouth of the bag which are so constructed that their required strength is secured without the introduction of any reinforcing material.

In the accompanyingdrawings, Figure I, illustrates in perspective a bag constructed according to my invention.

Fig. II, is a similar view of the folded blank from which the bag is formed.

Fig. III, illustrates the initial step in the formation of the handle.

Figs. IV, and V, show respectively the successive folds by which the bag top is reinforced in completion of a handle.

Fig. VI, is a cross sectional view through the handle, the lane of which is indicated by the arrows IVI in Fig. V.

Fig. VII, is a similar View on an enlarged scale showing the final step in rounding a handle.

The structure of the completed bag which is shown in Fig. I, will be beSikdlIldelStOOd by describing the process of folding and cutting by which it is constructed. I A single sheet or blank of stout paper is cut to the outline indicated and folded along the line 2, 2, of Fig. II. The flap 3, of one free edge is folded and pasted over the other free edge to form a tubular receptacle. The infolding bottom of the bag may be formed in any of the methods commonly used in bag formation and need not be here described.

The two sides of the bag are prolonged above their point of union in the form of long tapered tabs 5, 5, formed by suitable cutting of the sheet from which the body of the bag is formed. The top of each tab is rolled upon itself until the resultin pa er roll occupies about the line 6, 6, of ig. I. This sta e of bag formation is illustrated in Fig. II. The remainder of the tab is of the body of the bag is then folded along the crease 7 7, Fig. III, which is substantially midway between the roll 6, 6, and the line 8, 8, which is to form the top of the tubular body of the bag, so that when the roll is folded down it occupies a position glose to this line as seen in Fig. IV. The slde flap thus rolled and folded is once more folded over outwardly along the line or crease 8, 8, and in this position is secured to the upper part of the side of the body of the bag by suitable adhesive. As a result of this rolling and folding each side reinforced by a double thickness of paper along the region of its upper edge, and also carries within the upper fold of this reinforcement, the roll which has been formed of the upper end of the tab. A hand hole 10, is cut through the side of the bag and through the double reinforcing flap as shown 1n Fig. V, and immediately below the roll of paper. When this has been done a cross section of the upper edge of the side of the body of the bag is represented by Fig. VI, which shows such a section taken on the line 6, 6, of Fig. V. Thereupon the free edges which are formed just below the roll alon the upper edge of the hand hole are folded in preferably by putting the single thickness beneath the double thickness and causing them to adhere, in which completed condition the section of the completed handle is represented in Fig. VII. I The handle for the other side of the bag having been similarly formed, there is produced out of a single sheet of paper a stout bag or receptacle having reinforced re istering hand holes on both sides near t e u per edge, which edge at this point is stout y reinforced for the formation of the handles by the paper roll which it contains. The strength of the handle thus formed is very great. The reinforcement of the sides of the bag in the region of the hand holes is sufficient to impart great resistance to tearin strains, so t at it will be found that accor ing tomy invention I have produced a bag or rece tacle formed wholly of paper which is capa le of being used for the carrying of great weight and in which the hand holes will resist very great tearing strain. I have found that the rolls of pa er sufliciently strengthen the upper edge 0 the hand hole and form sufiiciently stout handles to require no interior reinforcement, and although such reinforcement might be inserted, it is not necessary and will not add materially to the strength of the bag, a characteristic of which is that the requisite strength is obtained Wholly by the cutting, rolling, folding and securing of the paper Without the need of any such reinforcement.

Having thus described" my invention, I claim:

1. A aper bag or receptacle having a body with its upper portion at each side rolled into a series of convolutions and infolded, so as to constitute a reinforced upper edge for said body, there being at the sides handholes through the reinforcement immediately beneath the aforesaid convoluted rolls.

2. A paper bagor receptacle having a body with dOuble reinforcement of its upper edge at each sidecomprising a doubly folded bag handholes through the reinforcement immediately beneath the paper rolls, so that the latter may serve as handles.

In testimony whereof I have hereunto signed my name at Philadelphia, Pennsylvania, this eleventh day of October, 1917.

CHARLES s. PEAsE.
