The smooth surface of permanently attached tab 25 is

of hinged junction 38 upward and apart into alignment

When the slide has been withdrawn to this extent it is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
panels 3 and 5. Triangular indentation 47 is centered in
the edge of the flap adjacent tab 25. Major part 24’ of
the visible surface is stippled to indicate the location of
adhesive, which may ‘be applied before or during the fold

Flap 22, whose width over most of its length closely
approximates ‘that of the other flap (and the narrow pan

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

in the interest of clarity, all showing of the bottom of

FIG. 3 shows in perspective the forming package of

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

at the free extremities of the two tabs. The upstanding

removed. Emptying of the package, which usually occurs
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

existing cigarette containers, the present one is free from
protrusions designed to aid manipulation of the closure

those others, by reason of the tight ?t assumed by an
outer cover of cellophane or the like.

after) a die-cutting of the blank outline, as can perfora

panel itself and is centered transversely thereof, and in

junction with the rest of the wall panel and approximates
the width of the closure slide at its attachment thereto.
