Claims. (Cl. 229—56)

This invention relates to bags, and more particularly to double-pocket bags.

This application is a division of my copending application Serial No. 741,440, filed June 6, 1958, entitled, Bags, which is a continuation-in-part of my now abandoned application Serial No. 491,829, filed March 3, 1955, entitled, Manufacture of Bags.

Among the several objects of the invention may be noted the provision of double-pocket bags of a flexible ’ heat-sealable sheet material such as polyethylene, wherein each bag is provided with a length of relatively narrow flexible heat-sealable material extending from one . side edge of the bag to the other adapted to serve as a carrying handle for the bag; and the provision of a double-pocket bag with a carrying handle constituted by a length of tape extending from one side edge of the bag to the other and so positioned that, with the bag held by the handle, both pockets of the bag are closed so that articles therein will not fall out. Other objects and features will be in part apparent and in part pointed out hereinafter.

The invention accordingly comprises the constructions hereinafter described, the scope of the invention being indicated in the following claims.

In the accompanying drawings, in which several of various possible embodiments of the invention are illustrated,

FIG. 1 is a perspective view showing certain steps involved in one method of manufacturing bags of this invention with carrying handles;

FIG. 2 is an enlarged section taken on line 2—2 of FIG. 1;

FIG. 3 is a perspective view showing certain steps in5» volved in another method of manufacturing bags of this invention with carrying handles;

FIG. 4 is a perspective view showing a bag with a carrying handle of this invention made according to FIG. 1 or FIG. 3 in a folded condition with items inserted in the two pockets thereof;

FIG. 5 is a vertical section taken on line 5—5 of FIG. 4;

FIG. 6 is a perspective view showing a bag with a carrying handle in a reversely folded condition from that of FIG. 4; and,

FIG. 7 is a vertical section taken on line 7—7 of FIG. 6.

Corresponding reference characters indicate corresponding parts throughout the several views of the drawings.

Referring to the drawings, FIG. 1 illustrates a method for manufacturing double-pocket bags of this invention with carrying handles. As shown in FIG. 1, a continuous web 31 of flexible heat-sealable material such as polyethylene has side marginal margins 33 and 35 folded over on lines 37 and 39, respectively, to lie flat against the surface of an intermediate portion 41 of the web.

As shown, the folded-over side marginal portions 33 and 35 are of equal width, slightly less than one-quarter the total width of the web 1, and their edges 43 and 45 are slightly spaced apart on opposite sides of the longitudinal center line of the web. As shown in FIG. 1, the folding over of the side marginal portions is downward so that the intermediate portion 41 of the web is upward.

The folding over of the side marginal portions of the web 31 is carried out while the web is being fed in the 5 direction of the arrow in FIG. 1. A continuous tape 47 of flexible heat-sealable sheet material such as polyethylene is unwound from a supply roll thereof (not shown) and applied to the outside of the intermediate portion 41 of the folded web extending longitudinally of 10 the web along the longitudinal center line of the web, thus being in centered relation with respect to the opposed edges 43 and 45.

The folded web with the tape 47 applied thereto is then heat-sealed and segmented on transverse lines 49 spaced 15 along the length of the web. This forms bags C such as are shown in FIGS. 1, 2 and 4-7. As shown, bag C has two opposed open pockets constituted by the foldedover portions 33 and 35 and the portion 41 forming a back wall common to both pockets. Portions 33 and 2q 35 constitute front wall portions, portion 33 extending inward over the back wall 41 from one end thereof (the fold 37) and portion 35 extending inward over the back wall 41 from the other end thereof (the fold 39). The front wall portions 33 and 35 are joined along the sides 25 thereof to the sides of the back wall 41 by heat-sealed seams 49. Portion 33 is integrally joined at its outer end to back wall 41 at fold 37. Portion 35 is integrally joined at its outer end to the back wall 41 at fold 39. The inner ends of the front wall portions 33 and 35 at 30 edges 43 and 45 are free of the back wall, thereby providing pocket mouths 51 and 53 (see FIGS. 4 and 5). The portion of the tape 47 which is segmented along with the segmentation of the web extends transversely of the bag from one side edge of the bag to the other on the 25 outside of the back wall 41 and is located centrally of the length of the back wall 41. The ends of the tape are heat-sealed to the side edges of the bag at 49.

As shown in FIGS. 4 and 5, the bag C may be folded in half along the longitudinal center line of the tape 47 ₄0 with the back wall 41 and the tape on the inside and items of merhandise such as indicated at 55 and 57 placed in the two pockets 59 and 61 of the bag through the pocket mouths 51 and 53. One type of item for which the bag C is particularly adapted is a pair of shoes, one shoe ₄₅ being placed in one pocket, -the other shoe in the other pocket. Then, as shown in FIGS. 6 and 7, the folding of the bag is reversed to bring the tape 47 to the outside and the pocket mouths 51 and 53 to the inside. In this condition of the bag, the tape 47 serves as a carrying 50 handle and the mouths of the pockets are effectively closed by the fold 63 made in the back wall 41.

FIG. 3 illustrates another method of carrying out the manufacture of bags C of this invention such as illustrated in FIGS. 2 and 4-7, the bags being made from 55 continuous seamless tubing 71 of flexible heat-sealable sheet material such as polyethylene. This method includes as its initial step the slitting of one wall of the tubing as by means of knife 23. The result of the slitting operation is a folded web like that of FIG. 1, and the ₆₀ remainder of the method is the same as that of FIG. 1.

In view of the above, it will be seen that the several objects of the invention are achieved and other advantageous results attained.

As various changes could be made in the above con65 structions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
