CONTAINER AND METHOD SEALING.

Application filed September 9, 1922. Serial No. 587,151. i

The object of this invention is to provide a novel container and method of sealing.

Inthe attached drawings: Figure 1, is a front view of a container made in accordance with my nvention;

Fig. 2, is a section on the line 2-2, F1g. 1; Fig. 3, is aback view of the container 11- lustrated in Figs. 1 and 2;

Fig. 4, is a front view-of the container 1 sealed; I

Fig. 5, is a section on the line 5-5, Fig. 4. Fig. 6, is a fragmentary enlargement of the upper portion of the. sealed bag as 11- lustrated in Fig. 5, and

15 Fig. 7, is a view in perspective of a container illustrating a modification within the scope of the invention.

In the industry, bags are distinguished from envelopes chiefly by the methods of manufacture, and by the fact that whereas in the envelope the sealing flap is on the front face, in the bag this flap (when provided) is on the rear face.v In sealing a bag in normal fashion, it accordingl is necessary to turn the flap down over t e front face, which mars the appearance of the container.

I have found, however, that a bag of the usual form lends itself to the development of a container which is particularly useful for second-class mail where it is necessary to leave the container sufliciently open to permit inspection of the contents.

With reference to the drawings, I have in Figs. 1 to 6, inclusive, illustrated a common form of bag, this bag, as will be seen, consisting of a tubular blank'l of paper turned back at the bottom and sealed as indicated at 2, the rear side of the blank at the top extend- 40 ing somewhat-above the front face to form a flap At the rear of the flap 3, I prefer to place an adhesive 4, such as is commonly used on the edges of envelopes, and it is" also preferable to score the bag near the top,

as indicated by the reference numeral '5,

' thereby to assist the folding back of the upr portion of the bag and insuring its lying flat when folded.- The bag so formed and secured as illustrated in Figs. 4 and 5 by turning back the upper portion of the bag along the scored line 5 and securing the flap 3 to the back of the bag by means of the adhesive 4, may beemployed for sending second or third-class matte-rs through the mails, this by reason of the fact that the turned-back portion 6 of the front face of the bag is held loosely in place only by its connection with the flap 3, and the bag may be distorted to permit passage of the hand under the flap and into the interior of the bag, or to permit inspection of the contents. Although th1s invention finds its most useful application in the case of the so- 7 called bags, it will be understood that it is not limited to this particular form of container. Thus, for example, as shown in Fig. 7, the flap 3 is eliminated, the front and rear faces of the container being of equal height, and the strip of adhesive 4 is secured to the upper edge of the rear face of the bag, so that when the upper portion of the bag is turned, back, this adhesive may act to effectively seal the container while still permitting. access to the interior without breaking the seal.

Still other modifications are possible with no departure from the essential features of the invention.

I claim:

1. A bag comprising a tubular blank sealed at one end and having one face extending at the other end beyond the end edgeof the other face, and an adhesive on the outside and at the open end of said bag constituting'securing means when the aforesaid open end is folded over to close the bag.

2. A bag comprising a tubular blank sealed at one end and having its rear face extending at the other and normally open end beyond the end edge of the front face, and an adhesive on the outside of the extension of said rear face constituting securing means when the said open end'is folded over to close the bag.
