A TTORNE Y5 Patented Mar. 26, 1935 UNITED STATES PATENT OFFICE Claims.

This invention relates to window envelopes, and particularly to the construction thereof in such manner as to provide means therein to prevent shifting of the insert in such envelopes, thereby 5 maintaining the address part in proper register with the window, even though the size of the insert be considerably smaller than that of the envelope, measuring the same from top to bottom.

As hereinafter more particularly pointed out, an advantage of the envelope of the present invention is that it permits the use of addressed inserts, the address portions of which are close to the upper margins of such inserts. Postal regulations require a designated minimum space between the window and the upper border of the envelope. The envelopes of the present invention provide this minimum space by being made over-size in the dimension from top to bottom, a tuck-in flap being provided to engage the upper edge of the insert and hold such insert from shifting with reference to the window.

Other objects and advantages will be apparent from reading this specification in connection with the accompanying drawing, in which Figure 1 is a rear View of an envelope embodying my invention in which the sealing flap is shown in extended position; and

Figure 2 is a similar view to Figure 1, in which the seaming flap is folded upon the envelope.

Referring now in detail to the drawing, in which similar characters refer to similar parts throughout, 3 is an envelope having a front flap 4 which extends upwardly from the face of the envelope and which for that reason will here- 'after be referred toas the face flap. The back of the envelope is designated as 5 and is provided with a flap 6, which to distinguish it from the face flap will be referred to as the back flap. A window is shown at 7.

Score lines 8 extend across the base of the back flap and occupy the connecting zone between the back flap and the back of the envelope, the purpose of which is to control the folding of the flap on a line best suited for the envelope insert. The back 5 of the envelope is preferably cut out at 9--9 to provide a correspondingly larger bending zone for the back flap, adapting it to be operative on different sizes of envelope inserts. The insert in the present envelope is indicated at 10.

In operation the insert 10 is entered into the envelope so as to rest at the bottom end thereof, the address on such insert occupying the portion designed to fit adjacent the window 7 and to be read therethrough. The back fiap 6 is then folded inwardly along a score line over the top of the insert so as to snugly hold the same against internal shift, and the front flap of the envelope may then be sealed against the back thereof.

The envelopes of my invention are especially 5 adapted for use with certain types of inserts such as invoices or cards employed in connection with automatic registers and the like, the address portions of which invoices, by reason of the set-up of such registers, are generally located adjacent 10 the upper margins of the invoices. If such invoices were inserted in ordinary window envelopes corresponding in size to the size of such invoices, the windows of such envelopes would have to be placed too close to the upper borders of the en- 15 velopes to comply with postal regulations, which I require a minimum space between such window and'the upper border.

The envelopes of the present invention are oversize in the dimension from top to bottom, 20 thus providing the necessary space between the top of the window and the upper border of the envelope, as will be apparent from the drawing. The cut-outs 9--9 of the back and the small tuck-in flap 6 provide a construction which, when the flap 6 is folded over the insert, will serve to hold the same in its proper relation to the window, as above noted.

I have described what I believe to be the best embodiment of my invention. I do not wish, however, to be confined to the embodiment shown, but what I desire to cover by Letters Patent is set forth in the appended claims.

I claim:

1. An envelope comprising a front having a window therein, a back, a fiap on the front divided from the front by a fold line which defines the upper edge of the envelope, the back having spaced cutouts extending below the upper edge of the envelope, and a back flap between said cutouts adapted to be folded inwardly to fit over an enclosure of less height than the envelope to hold said enclosure against shifting.

2. A window envelope provided with a front flap and a back flap, said back flap being adapted to be folded inwardly over the contents of the envelope and hold said contents against shifting, said back fiap having a scored zone at its 'base within the area of the back side of the envelope which is adapted to be covered by the front flap.

3. A window envelope having a face and back, a front flap secured to said face and a back flap secured to said back, the said back being cut out at the sides of said back flap to increase the window therein, a front flap adapted to be folded backward against the back of the envelope body, a back flap adapted to be folded forward into the envelope, said back flap being foldable along a line below and parallel to the line of fold of the front flap to fit an enclosure of less height than the envelope and hold the enclosure against shifting.
