the width of the wide panel, along junction welt 28. The
fully open position, attained by such triple-fold con?gura

When the slide has been withdrawn to this extent it is
folded through a right angle (along transverse fold line

to the width (horizontal dimension) of each of narrow

the edge of the flap adjacent tab 25. Major part 24’ of
the visible surface is stippled to indicate the location of

Flap 22, whose width over most of its length closely

panel 2 for approximately two-thirds of the wide panel
which is bounded by the top edge of narrow wall panel
3 and free edge portions 42 and 44 of wall panels 2 and
4 plus the near edge of the ?aps, is completely uncovered
by the slide.
The top of the inner wrapper is shown being opened
in this view (FIG. 7) by removal of end portion 30 there
of, as may be accomplished most simply by placing thumb
width along junction welt 26 at the top of that wide panel.
The ?ap narrows at its outermost edge, as a result of a
sloping of the edge closest to tab 23, and on indentation

FIG. 3 shows in perspective the forming package of

When the slide is in the fully closed position, hinged por

with the rest of that wall panel. Complete closure is posi

after from about ten to twenty openings and closings when
used for cigarettes, leaves it in good condition for sub

similar household ‘articles.
It is apparent that withdrawal of the closure slide to
