Inasmuch as it is desired that the cellulosic material entirely enclose the This is done preferably before the package is formed and the revenue stamp will overlie a side margin of the cap I so that when itistornloose by thepulling of the tape thestamp will be torn (note Figure 9 wherein the left-hand margin of the cap 4 is shown under the stamp S). It will be noted that the tearing strip bounds the openihg 3 and therefore in the pull of the tape the'cellulose' offers minimum resistance against the tearing action, the cap 4 being readily pulled away by reason of the fact that its adhesive bond to the cellulose will offer less resistance than a corresponding integral area of cellulose sheet.

Although in Figure 1 I have shown the opening at 3 as stamped out of an inner area of the cellulose sheet, the opening may be formed by incut'sections at the ends of the sheet as shown in Figure 11. when the sheet is folded over in the manner shown in Figure 12, these incut areas will lie in register to form an opening and to receive a cap 4 identical with that shown in Figure2.

In the figures, the full line l6 indicates the overlying edge of the cellulosic sheet at the top of the package and II the underlying edge of the opposite margin of the folded sheet.

The further modification as shown in Figures 15 to 17 inclusive, eliminates the necessity for a separate cap 4. To this end, one margin of the cellulose sheet is cut away at It and the opposite edge is formed with a larger-semi-annular projection ll terminating at the points a and b which may be slight cuts into the body of the cellulose sheet. when the cellulose sheet is applied, the projection It will lie over and will cover the opening I5 and .the tape will readily tear the cellulosesheet at the sides of the projection ll, particularly in view of the small cuts at a and b.

In the drawings I have shown the opaque wrapper O. P. in full lines inasmuch as the cellulose outer covering will be transparent. In the various figures only the folded over edge ll of the cellulose sheet and the cap 4 have been shown in full lines.

It will be understood that various modifica-' tions may be made in the embodiments illustrated in the drawings without departing from the spirit of the invention.

Having described my invention, what I claim and desire to secure by Letters Patent, is as follows:--- i 1. In window forming means for packages comprising an inner folded wrapper and an outer transparent cellulosic covering sheet, a tearing strip folded in rectangular formation to bound a corresponding portion at the inside of the upper folded laps of the inner wrapper, an end of the strip being projected outwardly from the package and an outermost wrapping sheet of transparent cellulosic material having an area cut away to form a window adjacent said rectangular formation of the strip, and a covering cap for said window.

2. In window forming means for packages comprising an inner folded wrapper and an outer transparent cellulosic covering sheet, a tearing strip folded in rectangular formation to bound a corresponding portion at the inside of the upper folded laps of the inner wrapper, an end of the strip being projected outwardly from the package and an outermost wrapping sheet of transparent cellulosic material'having an area cut away within its margin to form a window and a covering cap secured by adhesive to the area of the sheet at the sides of said cut away area, said cap lying over said rectangular formation of the strip.

3. In window forming means for packages comprising an inner folded wrapper and an outer transparent cellulosic covering sheet, a tearing strip folded in rectangular formation to bound a corresponding portion at the inside of the upper folded laps of the inner wrapper, an end of the strip being projected outwardly from the package and an outermost wrapping sheet of transparent cellulosic material having an area cut away to form a window adjacent said rectangular formation of the strip, a sealing stamp strip applied to the top of the wrapper, and a covering cap for the window having a marginal area projected under the sealing stamp strip.

4. Window forming means for packages constructed in accordance with claim 1, in which the window is formed by opposed cut away marginal areas of a sheet of transparent cellulosic material.

5. Window forming means for packages constructed in accordance with claim 1, in which the sheet of transparent cellulosic material is formed at one margin with a cut away area and is formed at the opposite margin with a projecting lip to form a covering cap for said cut away area when the sheet is in folded position
