ops, particularly of the type adapted to' transmit mail matter at third class rates.

()ne object of the invention is to provide an envelop of this character in which the contents may more readily be inserted than in the type of envelop using open flaps.

Another object is to provide an envelop of this character in which the contents is securely held and is still removable to comply with the requirements of third class mail matter postal regulations.

The arious further objects and advantages will more fully appear from the de tailed description and the features of novelty will be particularly pointed out in the claims.

In the drawing illustrating'this invention, Figure 1 is a perspective view of the im proved envelop with the mouth thereof opened by the pressure of the fingers along the edges while the contents is being inserted. Fig. .2 is a plan view of the envelop illustrating the slit. Fig. isa developn'ient of the blank out of which the envelop is made. Fig. 4 is a plan view of a modified form of envelop. Fig. 5 is a perspective view illustrating the manner in which the contents of the envelop may be removed without tearing the stamp. Fig. 6 is a plan view of an envelop having a modified form of slit.

Referring in detail to the drawing, par ticularly to Figs. 1, 2, 3 and 5, the envelop comprises the face 10, back 11 and scaling flaps 12, 13 and 14. These flaps are'perrnanently sealed, forming an envelop closed at all ot'the edges. To provide a mouth for the envelop, I form along one edge of the envelop, preferably across the face of the envelop, a slit comprising straight portions 15 and 16 adj acent to the edges and a curved intermediate portion 17 uniting the straight portions. When itis desired to open the mouth of the envelop to insert the contents, pressure is applied alongthe longitudinal edges as indicated in dotted lines in Fig. 1,

' the postage stamp ing' flaps extendi which causes the curved portion 17 of the slit to open wide, thereby pernntting the easy insertion of the contents. The stamp 18 is then applied directly over the straight portion 15 and part of the curved portion 17, thereby closing the slit at that point and preventing the accidental loss of the con tents. However, the latter can he removed without tearing the stamp as clearly indicated in Figv It is to be noted that the fingers may be inserted through the open portion of the slit and the contents folded and turned so as to remove it in a narrower compass than its full width. This requires special mani nilation and, therefore, it will be readily seen that the papers in the envelop cannot he accidentally lost.

In the modified form illustrated in Fig. 4, a form of envelop is shown in which the flaps 22 and are triangular in form as in the ordinary envelops now in use. HoW-' ever, these flaps are sealed and the mouth of the envelop is formed by the slit 15, 16, 17 as in the other form described.

In the modified form illustrated in Fig. 6,

the slit is formed with the straight portion 31 and the transverse portion 32 and portion opening along the edge, and. terminates in another diagonal portion 3% at the bottom. lVhen the stamp 18 is inserted over the portion 31 or over both portions 31 and 32, the contents cannot be removed except in the manner illustrated in Fig. 5.

It will be noted from the above description that my improved envelop permits easy manipulation in inserting the contents as the envelop merely has to be grasped andpressure applied along the edges whereupon the mouth opens wide to receive the papers. The envelop is sealed by the insertion of and the form of the slit may be such as to secure the most effective opening and sealing. Althoughthe envelop is virtually sealed, it may besent under third class matter rates; The blank consists of one piece of flexible paper and the slit may be cutby the same die which cuts the outline of the blank.

Having thus described my invention, '1

claim as new and desire to secure by Letters Patent:

1. A mailing envelop comprising a uni tary blank having a face and back and sealpg therefrom along the marginal edges, said blank being formed with a slit extepdiiig the width of the face mit the ready opening of the envelop when 10 thereof, said slit being formed with a curve pressure is applied to the edges. whereby it forms a mouth which ieadily Signed at New Ynrk in the county of New opensby pressure along the edges of the York and State 01' New York this 5th day envelep. of August A. D. 1915.
