Pat nted May 22,1917,

Application filed ll larch 16, 1916. Serial no. 84,526. i

To all whom it may concern:

Be it known that I, MASAO TANAKA, a subject of the Emperor of Japan, and a resident of New York city, borough of Manmentioned, provided with an inside flap' for preventing the string or analogous memher, when used for the purpose stated, from scattering or pulling out the contents of the envelopsthe flap also serving to normally prevent the string from dropping into the envelop, as well as to prevent the contents of the envelop from fouling the string.

Reference is to be made to the accompanying drawing forming a part of this specification, and in which like letters indicate like parts in all of the views.

Figure 1 is a view, partly in perspective and partly broken away, showing my improved envelop as it appears while it is be-' ing opened after being sealed.

Fig. 2 is a view, partly in perspective and partly broken away, showing the envelop as ready to receive its contents.

Fig. 3 is a substantially central vertical section through the envelop, substantially in the condition in which it appears in Fig. 2.

Fig. 4 is a detail, showing in elevation the inner flap or shield of the envelop.

The body. of the envelop is shown at 5, and the sealing flap at 6, the latter being provided along its outer or free edge with a thin layer 7, of adhesive material.

The envelop is provided with a bend or fold 8, and with a row of perforations 9,

this bend and the row of perforations ex-' tending along it serving as the line of demarcation, separatlng the flap 6 from the rest of the envelop, all parts of the device thus far described however, being prefer ably integral. In Flg, 4, I. showa separate plece 10,

which is secured, by use of an adhesive or in some other convenient manner, within the envelop body as indicated in. Figs. 1 and 2, and when thus secured this part is designated as the inner .flap. It is provided with a folding line 11 and with a relatively wide portion 12, carrying an adhesive surface 13 whereby. this member is, secured inv 7 position: Between the adhesive surface 13 v and the folding line 11 the portion ofthe member 12 is free of the envelop body, as indicated in Fig. 3.

A flexible member 14, preferably a string or wire and hereinafter designated for convenience as a string, extends alongthe envelop body, and substantially parallel to the adhesive surface 13. That is, the string extends between the inner surface of the envelop body and the adjacent free surface of the inner flap, and protrudes slightly from one end of the envelop body. The

string is secured by a drop of adhesive 15 to the inner surface of the envelop body and.

the adjacent surface of the inner flap.

The operation of mydevice is as follows: The parts being arranged as shown in Figs. 2 and 3, the complete envelop is ready foruse and may be filledwith papers, merchandise or the like. Forthis purpose the inner flap is raised or opened, the articles are placed in the envelop, and the inner flap is brought over them. Next the-sealing flap 6 is brought down over the inner flap, and sealed in the usual or any desired manner.

In order to open the envelop, the operator grasps the protruding end of the strlng and by pulling it laterally away from the envelop he rips the-paper along the fold1n g line 11, the perforations 8 facilitating th1s object. In using the string for th1s purpose, the inner flap is not disturbed. As

soon as the envelop is thus ripped open, the operator raises the inner flap and removes the contents of the envelop. I t

It will be noted that after the envelop 1s filled and sealed and before it is opened, the string lies 1h 'what is essentially a l1ttle crevicethat is, a lengthy space between a part of the. inner flap and the adjacent 1n ner surface of the envelop. The string while in this position is protected in the sense that it cannot be fouled by the contents of the envelop, andit is prevented, when pulled inorder to open the envelop, from disturbing the contents thereof.

- combination of an envelop Having thus described my invention,

What I claim as new and desire to secure by Letters Patent is as follows:'

In a device of the character described, the body provided with a sealing flap and with a row of perforations, a ripping cord secured at one of the row of perforations by pulling upon said ripplng cord, and an inner flap secured at one of its edges within said envelop body and bentback upon itself in order to main tain separation between said ripping cord and the contents of said envelop body, said ripping cord extending along the outer surface of said inner flap and free to move away from said inner flap without mutilating the same.

MASAO TANAKA.
