Description

Patented Oct. 6, 1936 UNITED STATES PATENT OFFICE BAG Application June 14, 1935, Serial No. 26,539

4 Claims.

This invention relates to bags and is particularly directed to bags made of paper, Cellophane, glassine or a combination of such materials.

The preferred form of my invention contemplates a bag one wall of which is made of one kind or color of material and the other wall of another kind or color of material. The entire bag may be made of the same kind and color of material, if desired, but it will be appreciated that varied decorative effects may be accomplished by using different materials as well as colors for the two walls.

In the manufacture of the bag of my invention I prefer to employ two strips of material of different length. One strip which is to constitute one wall of the bag is slightly wider than the gtrip which is to constitute the other wall of the The strip of narrower and shorter material, which in the preferred form of my invention is transparent material, is superimposed centrally so far as side edges are concerned, of the wider strip, which in my illustrated form is opaque paper, but in offset relation so far as its ends are concerned so as to provide an assembly of two strips face to face, with the transparent material projecting from one end and the opaque material projecting from the other end.

The sides of one strip project beyond the sides of the other strip and the projecting side edges or flaps of the wider strip thus provided are folded over upon the sides of the narrower strip to form two longitudinal seams which close the side of the bag. These seams are the only seams in the bag and it will be appreciated that a considerable saving of material is effected over bags as previously constructed wherein the two strips of material are of the same length and where a third longitudinal seam is provided in the front of the' bag. One advantage in eliminating the front seam is the provision of a smooth seam-free surface available for printing and a further advantage is increased strength since it is well known that failure often occurs at the seam.

A further advantage of my improved bag over prior bags is that in its preferred form the edge of the shorter transparent material may be turned back upon itself to provide a reinforced edge at the open end of the bag, the transparent material being readily ruptured or torn at the edge. The present invention eliminates this trouble. If the reinforced edge at the mouth of the bag is not required the transparent or shorter wall of the bag may be made still shorter resulting in an even greater saving of material.

Still further advantages of my improved bag over prior bags will be manifest from the following description and the accompanying drawing, in which:

Fig. 1 is a perspective view of a bag before the bottoming or reinforcing operations are performed;

Fig. 2 is a perspective view of the completed a Fig. 3 is a sectional view on line 3-3 of Fig. 2;

Fig. 4 is a perspective view of the bag in open position;

Fig. 5 is a fragmentary view of a modified form of bag; and

Fig. 6 is a similar view of another modified form of bag.

Referring to the drawing in detail and first of all to the form of bagv illustrated in Figs. 1 to 4, inclusive, I designates a seamless paper strip which is to constitute one wall the front, for example, of the completed bag. A strip of Cellophane, glassine or other transparent material 2 constitutes the other bag wall. These two strips are assembled face to face, but the paper strip I being materially wider than the strip 2 the sides 3 and 4 of this strip may be folded or tucked to provide side pleats 5 and 6, respectively, and projecting side flaps I and 8 which are folded over upon the face of the transparent strip and secured thereto by paste, glue or in any other suitable manner to close the sides of the bag.

It will be noted from Fig. 1 that the paper strip I and transparent strip 2 are not of the same length and while the transparent strip 2 is centrally located upon the paper strip I so far as the side edges of the strips are concerned, the

strips are offset longitudinally to provide either an even edge or a more or less projecting flap 9 of transparent material at one end and a projecting flap I0 of paper at the other end.

In finishing the bag the projecting flap' 9 of transparent material which is at the open end of the bag may be folded over upon itself as seen in Fig. 2- to reinforce the edge of the same, therebyyto reduce to a minimum tearing of the matei lal at this end of the bag when filling the sa -me, or it may be left unfolded as in Fig. l.

" The bottom of the bag is formed by folding over the projecting paper flap I0 and both walls at the bottom of the bag length along the transverse line II so that not only is the flap II'I i'olded over but also the end I2 of the transparent material as shown in Fig. 3 to provide an exceedingly strong bottom.

The form of bag illustrated in Fig. is similar to that of Figs. 1 to 4, inclusive, except that in Figs. 1 to 4 I have illustrated a pleated bag whereas in Fig. 5 the bag is not pleated. This bag comprises a paper wall 20 and transparent wall 2|, the sides 22 of the paper strip which is wider than the transparent material being folded over and secured to the transparent material as in Fig. 1. This bag may also be reinforced at its open end by folding over the flap 23 and the projecting flap 24 at the bottom end of the bag is folded over as in the bag of Fig. 1.

In Fig. 6 I have illustrated a bag made up of transparent strip 30 and opaque strip 33, the transparent material in this instance being longer and wider than the strip 33. The projecting side flaps 3| of the transparent material are folded over upon the face of the opaque material to close the sides of the bag, while the projecting flap 32 of transparent material is folded over upon the face of the opaque material to bottom the bag. As inthe other embodiments of my invention the projecting flap of transparent material at the mouth of the bag may be folded over upon itself to reinforce its edge.

It will be understood that various changes may be made in the bag herein illustrated and described without departing from the spirit and scope of my invention.

What I claim is:

1. A bag comprising a strip of seamless flexible opaque material constituting one wall of the bag, a strip of transparent flexible material constituting the other wall of the bag, said strips being secured to each other face to face to form longitudinal side seams, and oil'set longitudinally to provide a projecting flap of opaquematerial at one end of the assembly which is folded over upon and secured to the face of the transparent material to bottom the bag, and to provide a projectin'g flap of transparent material at the other end of the bag which is folded over upon itself to reinforce the open end of the bag.

2. A bag comprising a strip of seamless flexible material constituting one wall of the bag, a strip .of different flexible material constituting the ferent lengths and so disposed with respect toeach other that a projectingflap of one material is provided at one end of the assembly and a projecting flap of the other material at the other end, the projecting flap at one end of the assembly being folded over upon and secured to the face of the other material to bottom the bag, the projecting flap of the other material at the other end of the assembly being folded over upon itself to reinforce the edge of the open end of the bag.

3. A bag comprising a strip of seamless paper or like material constituting one wall of the bag and a strip of transparent material constituting the other wall of the bag, thepaper strip being wider than the transparent material, the latter being disposed centrally of the paper strip with respect to the sides of the strips so that the sides of the paper strip project beyond the sides of the transparent strip, the strips being offset with respect to each other longitudinally to provide a projecting flap of paper at one end and a projecting flap of transparent material at the other end of the assembly, the projecting sides of the paper strip being folded over upon and secured to the face of the transparent material to form two longitudinal seams to close the sides of the bag, the paper flap'being folded over upon the turned over sides of the paper strip and upon the face of the transparent material and secured thereto to bottom the bag, and the projecting flap of transparent material at the other end of the assembly being folded over upon itself to reinforce the same.

4. A bag comprising a strip of seamless paper or like material constituting one-wall of the bag and a strip of transparent material constituting the other wall of the bag, the paper strip being wider than the transparent ma erial, said transparent strip being disposed centrally of the paper strip with respect to the edges of the strips so that the sides of the paper strip project beyond the sides of the transparent strip, both strips being offset with respect to each other longitudinally so as to provide a projecting flap of paper at one end and a projecting flap of transparent material at the other end, the projecting sides of' the paper strip being folded over upon the transparent material to close the sides of the bag, the projecting end of the paper strip being folded over upon the transparent material alonga transverse line within the adjacent end of the transparent strip to bottom the bag, and the flap on the transparent material at the open end of the bag being folded over upon itself to reinforce the edge of the same.
