Application 23, 1949, Serial No. 100,885 r My invention relates. to, a new method of; bag closure with labels. and to the. completed bag achieved by practicing this. method- My invention relates more, part ul rly. a e o of pIQ-fifitdflhlflfiflt of labels to. bags of the type that are made of heat-sealing material such as cellophane, Pliofilm or other vinyl or similar materials which are capable of being formed into bags from a roll of the material, the bag being formed in a continuous tubular structure by heat-sealing a folded-over section and then cutting the tube at desired lengths, at the same time heat-sealing one end of the bag shut.

Bags or containers of this type are used for packaging a wide variety of products, the bag being preferably transparent or translucent so that the product can easily be seen in the bag, and the product normally being provided with a printed label of paper or other material that is attached to one end of the bag. The label usually forms a loop between its attaching means to the package and its folded-over end, so that the filled packages can be mounted for sale or display on stands or racks, the label after attachment acting as a hanger or support for the filled package.

Bags or packages of the type described are in wide use throughout the country today, and in the usual procedure the open-ended bags are filled with the product, such as potato chips, popcorn, etc., at the factory, and after being filled the open end is heat-sealed or otherwise secured, and a label designating the product is then folded over the closed end and adhered or fastened in position by staples or other suitable means. The loop at the end of the label is then passed over a bar on a display rack where the packaged product hangs suspended until sold.

In the improved construction and method which I provide, considerable time is saved at the factory where the product is packaged because the bags or containers are furnished to the factory with the label already attached in such a way that after the product is placed in the bag it is hermetically sealed therein when the open end is closed.

For a more comprehensive understanding of the method and product which I provide, reference is had to the accompanying two sheets of drawings, upon which Fig. 1 is a front perspective view of the type of open-ended bag which I employ;

Fig. 2 is a similar view of the bag showing the manner in which a label designating the product to be placed in the bag is folded over the'sealed end of the same;

can was his. 3. shows the staple or. other fastening means in position firmly. attaching the label to the closed end of; the bag, the. folded-over end of the label being sufficiently spaced from the end of the bag so that the. filled bag may be slipped upon a support rod on a display stand;

Fig. 4 is a front perspective view of the completed bag and label shown in Fig. 3 open to be filled with a product such as popcorn; and

Fig. 5 is. a front elevational view showing the filled bag of popcorn, with the open upper end sealed and now forming the bottom of the bag.

In the embodiment of the invention which I have chosen to illustrate and describe, I have shown in Fig. 1 a bag l0 formed in the manner heretofore referred to of cellophane, Pliofilm or other heat-sealing material, the bag being formed with the longitudinal sealed seam I2 having the open end l4 and the cross heat-seal at its lower end to close the same. This is the usual manner in which bags of this type are constructed, the heat-sealing of the end of the bag normally taking place at the same time that the bag is cut off from the tube, leaving the open end of the following bag.

In carrying out my method I next take a label 18, which may have indicia 20 thereon indicating,

the product to be placed in the bag, and fold the: I6 of the bag so that it has.

label about the end a portion 22 on the front of the bag and a foldedover portion 24 at the back of the bag, the label. thus providing a loop 26 spaced from the end of the bag.

I next adhere the label to the bag In in any suitable manner, either by gluing or stapling, in which case I provide the staples 28 which fasten the label to the bag, the staples passing through the area of the heat-seal 16 across the end of the bag. After this has been done the bag is inverted with the open end I4 at the top, and it is filled with popcorn or otherproducts.

After the filling operation takes place at the manufacturer's factory, the open end of the bag is preferably heat-sealed shut, forming the seal 30 at the open end of the bag. The filled bags may now be inverted again so that the label 20 is at the upper end, and in this condition they may be placed upon racks for sale, storage or disposal.

From the above and foregoing description it can be seen that I have provided a comparatively simple manner of providing manufacturers with open-ended bags of the type described, the label being pro-attached to the same before they are filled with the product to be sold, so that after the filling operation it is only necessary to close the open end and the product is ready for sale and distribution.

By attaching the labels to the bag through the sealing area, at the closed end before the bags are filled, it can be seen that the bag is not pierced in any manner so that air can reach the product enclosed therein, thus adding greatly to the taste, freshness and quality of the packaged product.

While I have illustrated and described a specific embodiment of the invention, it will be apparent to those skilled in the art that changes and modifications may be made in the exact details shown. I do not wish to be limited in any particular; rather What I desire to secure and protect by Letters Patent of the United States is:

As an article of manufacture, the combination of an open-ended bag constructed of air-tight and water-tight material of the type which may be fused together by a heat seal. said bag having parallel side edges and end edges and formed with a longitudinal sealed seam medially of its two side edges throughout its length, a cross heat-seal applied at one end to form a sealed seam, and a paper label folded about the closed edges of the bag so that it has a portion overlying the front of the bag and a portion overlying the back of the bag and forming a loop spaced from the end of the bag, said label secured to said bag through said sealed seam whereby an open ended bag, label and hanger are provided which may be filled with a perishable food product and the open end closed with a sealed seam to effect an air-tight and water-tight package.
