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. In window forming means for packages
comprising an inner folded wrapper and an outer
transparent cellulosic covering sheet, a tearing

the opposite margin of the folded sheet.
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
