" ‘At S I have shown a usual revenue “stamp ap 45 plied .to ‘cigarette packages_ ’ It will be noted that the‘ projected end of the tape R lies ad jacent the revenue stamp, although in practice, a part of the tape may lie under the stamp 50 so that when it is pulled upwardly to tear out a rectangular opening in the wrapper, the stamp will be torn. In the use of the transparent cellulose outer wrapping sheet, it may be applied simultaneously 9,121,448 the inner wrapping sheet, or sheets, as own in Figure 6, and hence the projected end tape R will lie outwardly from the top edge the sheet and will project in the manner in Figure 8. Inasmuch as it is desired that the cellulosic material entirely enclose the This is done preferably before the 10 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 the stamp will be torn (note Figure‘ 9 wherein the left-hand margin of the cap 4 is shown under 15 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 20 that its adhesive bond to the cellulose will offer less resistance than a corresponding integral area of cellulose sheet. 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 pack age and an outermost wrapping sheet of trans parent cellulosic material having an area cut away to form a window adjacent said rectangular formation of the strip, and a covering cap for 16 said window. 2.

The further modi?cation as shown in Figures 15 to 17 inclusive, eliminates the necessity for outer transparent cellulosic covering sheet, a tearing strip folded in rectangular formation to 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-annu lar projection ll terminating at the points a of transparent cellulosic material having an _Figure2. In the 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 45 cover the opening I5‘ and .the tape will readily tear the cellulosesheet atvthe sides of the pro jection ll, particularly in view of the small cuts at ‘a and b.
