, pertains to make and use the same.

The present invention relates to envelopes or the like for enclosing letters and other matter adapted to be transported through the mails.

An object of the present invention is to provide a structure of envelope which may be easily and economically produced from a single blank of substantially rectangular form and which requires but few operations, and a blankwhich may be used as an envelope for enclosing a letter sheet, or which may be written directly upon to provide the letter sheet` itself.

Another object of the invention is to provide an envelope ofthis character which' may be quickly and easily sealed and which may be easily mutilated when being opened to gain access to the interior of the envelope :'10 and which is provided with a closing sheet adapted to be used in connection with a body part of the mutilated envelope for return use of the device.

With the foregoing and other objects in view, the invention will be more fully described hereinafter, and will be more particularly pointed out in the claim appended hereto. v

In the drawings, wherein like symbols refer to like or corresponding parts throughout the several views.

Figure 1 is a front elevation of the envelope constructed according to the present invention-and being sealed.

Figure 2 is a longitudinal section taken through the same substantially on the line 2 2 of Figure 1.

Figure 3 is a plan view of the blank from which the envelope is made, and showing the normal position Vof the device 'when it is open and ready for use.

Figure 4 is a perspective view of a supplemental closure sheet adaptedfor use with the envelope, and

Figure 5 is a rear face view of the closure sheet havingthe marginal flaps thereof fold- :l

kedover.` ;1 Referringto the drawing v1() designates the front wall of an envelope which isy preferably integral with the back wall,11.-.'The front and back walls 10 and 11 areof substantially the same dimensions and are Afoldable one upon the other ona crease -line 12. The blank providingv the front and rear i walls 10 and 11 has longitudinal. lines' o f perforation 13 which' are placedinwardly from the longitudinal edges of the blankVVA y 1 and extend throughout the entire length of the blank, andthe blank is also providedV with transverse lines of perforationskll spaced inwardly from the opposite ends `of the blank. y forations form marginal edge flaps which extend entirely about the blank. The marginal liaps about the three exposed edges y of the back Awall 11 have a coating of'an adhesive, as shown in'Figure 3, and are adapted'to be secured by the adhesive to the corresponding flaps of the front wall'when the latter is folded over on the line 12 to thus seal the envelope at its open edges.

The front wall 10 is adapted upon its face to bear the address of the party to whom the envelope is to be sent, and also adapted to carry the usual postage stamp 15 which may be secured thereon by an adhesive, orwhich may be impressed and. printed directly upon the paper or other material of which the envelope is made.

A Vletter sheet or other device may be placed between the walls 10 and 11 and the' latter sealed together at their marginal portions by moistening the adhesive layer on the flaps of the back wall 11. When sealed the envelope is closed at its marginal edges as shown in the sectional view in `Figure 2, when it is desired to gain access to the con- These lines 13 .and 14: of per? i se. y

tents of the envelope the adhering marginal Figures l and 5. rIhe sheet 16 is substantially of the same dimension as the back wall11 of the envelope and has longitudinal and lateral lines 17 and 18 of perforations sheet 16 may be used such as shown 1n f at its top and bottom edges and at one end edge to degne separable edge flaps about the seling sheet?.` The other end of the sheet 16 is provided with a, larger flap 19 which may be nsed 4:is the closure Hep of the envelope. As shown in Figure 5, the front and rear Walls lO and 11 of the envelope may be folded together and enclose e letter sheet and then placed `against the regir face of the sealing sheet 16 and the niarginal ilapsvof the latter turned over the edges of the Walls 1Q and 1l andsecured byan adhesive tothe rear face of the rear Well 11.

y For this pnrpose the marginal flaps olf' the sealing sheet-16 may be provided'with a` cpitingof Suitable adhesive as shown Figure If `desired thefsmaller flaps of thseeling sheet may rstbe turned over and `gnmnfied in place v'zi-nd' the larger Hap v 9`1i0ft open until the Inatterto be mailed "Tlie'iap 19 may then be secured over the rear" vll'l'to'selal the contents Within the encloeire. itis vapparent tht fthe sealing sheet-'16 rneybe used in connection with one or iiiore of the vWalls lof the envelopey end it provides a vnewv surfece on its'tr'ont fece for l:in `address of a, person to receive thepeeka'ge ind that it also mayreceive a stenlp" 'i5 1by either separate application or tirent mprsien and 'Printing- Qbvieus, that verQuS' 'changes @ed inodications may be mede in the details of construction and design of the above specifi* cally described embodiment of this inven-l tion Without departing from the spirit thereof, snch ,changes and modifications being restricted only by the scope of the following claim.
