ENVELOPE
Abstract
An envelope, and a unitary blank for making the same, having a
rectangular panel joined to another panel at one end by a
connecting strip and having a slit at the other end is disclosed.
The connecting strip is folded where it joins the rectangular panel
and the rectangular panel is then folded transversely along a line
slightly offset from the transverse axis. A pair of tabs formed by
the slot are then folded over to seal the envelope. The connecting
strip is extended into the rectangular panel by perforations which
can be torn thereby allowing the user to pull the strip and second
panel outwardly thereby exposing hidden writing through a window
provided in the rectangular panel.

Description
FIELD OF THE INVENTION
This invention relates to envelopes broadly, and more particularly
to an envelope of the type having a pull-out tab and the whole
being made from a unitary blank.
BACKGROUND OF THE INVENTION
A multiplicity of specialty-type envelopes is on the market, each
designed for a particular purpose. Examples of such types of
envelopes are window envelopes for the insertion of letters, bills,
or the like with the addressee's address being visible through the
window. Another speciality-type of envelope is one which combines a
mailing envelope, a printed bill or other correspondence, and a
return envelope all in one unit. Various other types of envelopes
have been designed for use in contests, "give-aways," and other
types of promotional activities. Many of these envelopes are
designed so as to convey the impression that there is hidden
information within which will be revealed to the recipient at an
appropriate time, thereby indicating whether or not the recipient
is a "winner." These various types of envelopes are complicated in
design and extremely difficult and costly to assemble on a large
scale for a mass mailing.
BRIEF DESCRIPTION OF THE INVENTION
Accordingly, it is a primary object of the present invention to
provide an envelope with a pull-out tab which is free of the
aforementioned and other such disadvantages.
It is another primary object of the present invention to provide an
envelope with a pull-out tab which is simple to construct and
inexpensive to manufacture.
It is a further object of the present invention to provide an
envelope with a pull-out tab, the complete assembly being made from
a single unitary blank.
It is yet another object of the present invention to provide an
envelope with a pull-out tab, made from a single unitary blank,
wherein the pull-out tab can be separated from the main portion of
the envelope and manipulated so that printing or other indicia
thereon become visible through a window in the envelope.
It is another object of the present invention to provide a single
unitary blank for an envelope with a pull-out tab, which blank is
simple and inexpensive to manufacture.
In accordance with the foregoing objects, a blank is provided
having a first rectangular panel joined at one end to a second
panel through a connecting strip. The first panel has a slot cut in
its other end thereby forming a pair of tabs. Two parallel rows of
perforations extend inwardly at the first end essentially defining
a continuation of the connecting strip. The perforations are joined
by a die-cut slit. The envelope is formed by folding the connecting
strip at the end of the first panel and then folding the first
panel in half transversely with the two tabs extending outwardly.
The connecting strip and second panel are then enclosed within the
first panel. Finally, the tabs are folded over and adhesively
sealed.

DETAILED DESCRIPTION OF THE INVENTION
For a proper understanding of the present invention it is helful to
first consider the construction of the blank used to make the
pull-out tab envelope. To this end, attention is first directed to
FIG. 1 wherein there is shown a blank generally designated by the
number 10. This blank is a single unitary piece which is formed
into the envelope by a series of folds. The blank 10 includes a
first elongated rectangular panel 12, a second panel 14, and a
connecting strip 16. The rectangular panel 12 has a pair of
parallel opposed edges 18 and 20 and a pair of parallel opposed
ends, first end 22 and second end 24. The blank is made of any
suitable material such as paper, cardboard, or a suitable plastic.
Paper, of course, for economic reasons, is the preferred material
of construction. A suitable adhesive is applied in a narrow strip
along the edges 18 and 20, thereby providing adhesive portions 26
and 28. First rectangular panel has a transverse axis A--A and a
longitudinal axis B--B.
Second panel 14 has a first edge 30 and a second edge 32.
Connecting strip 16 joins first panel 12 at the first end 22 with
second panel 14 at the first edge 30. First panel 12, second panel
14, and connecting strip 16 are coaxial along longitudinal axis
B--B. Connecting strip 16 has a pair of opposed parallel edges 34
and 36 which are extended into first panel 12 in the neighborhood
of first end 22 in the form of a pair of parallel rows of
perforations 38 and 40. The perforations 38 and 40 are joined by a
die-cut slit 42.
At the second end 24 of first panel 12 is a notch 44 of
substantially the same width as connecting strip 16, although it
could be slightly wider for ease of operation as will be seen as
the description hereof proceeds. The notch 44 is centered about
longitudinal axis B--B and therby forms a pair of equal tabs 46 and
48. The tabs will be folded along first fold line 50. A second fold
line 52 is provided halfway between first end 22 and first fold
line 50. Essentially, second fold line 52 is displaced toward first
end 22 from the transverse axis A--A by a distance equal to
one-half the depth of notch 44.
In use, the desired printing, which is to be kept hidden from view
until the user is to observe the same, is printed on second panel
14 and/or connecting strip 16. Connecting strip 16 is then folded
upwardly along first edge 22 so that it is superposed on first
panel 12. First panel 12 is then folded in half along second fold
line 52 thereby sandwiching second panel 14 and connecting strip 16
therewithin. The adhesive strips 26 and 28 then join the folded
halves of first panel 12 together. Finally, tabs 46 and 48 are
folded over and adhesively secured, thereby providing a sealed
envelope 54 as shown in FIG. 2. The perforations 38 and 40,
combined with the die-cut slit 42, form a lifting tab 56. When the
recipient of the envelope desires to read the hidden message he
lifts the tab 56 by inserting a fingernail into the die-cut slit 42
and tearing the tab along perforations 38 and 40. The assembly
comprising the second panel 14 and the connecting strip 16 is then
separated from first panel 12 and may be slid outwardly until first
edge 30 reaches the fold 50. A hidden message on second panel 14 or
connecting strip 16 will then be visible in the window created by
the removal of tab 56.
Attention is now directed to FIG. 3 wherein there is shown another
embodiment of the instant invention. In this embodiment, a separate
window 58 is cut into first panel 12. Second panel 14 and
connecting strip 16 are shown with various indicia thereon showing
a particular use to which the envelope can be put. Thus, as can be
seen in FIG. 4, a questionmark appears in window 58 before the tab
56 is torn loose and withdrawn. When tab 56 is torn loose by
die-cut slit 42 and perforations 38 and 40, the word "pull" becomes
visible through the window created by the removal of tab 56. When
the assembly is then pulled, the winning, or losing, number or
other indicia appears in window 58.
In still another embodiment, as shown in FIG. 5, a blank is
provided having a plurality of windows 58. Each window represents a
number as, for instance the winning number in a horse race. The
winning number, as indicated by the figure of a horse with a rider
60 is printed on second panel 14 so that it will be aligned with
one of the windows 58. As shown in FIG. 6, on the outside of the
envelope is printed numbers and pictures of horses corresponding to
those numbers. Questionmarks printed on connecting strip 16 and on
first panel 12 appear in the windows 58. When tab 56 is lifted the
word pull and an arrow will appear. The assembly is then pulled
thereby aligning a horse in one of the windows 58 thereby
indicating the winner, or loser.
Returning momentarily to FIG. 2, wherein second panel 14 and
connecting strip 16 are shown in dotted lines, it will be seen that
the distance from first end 22 to second edge 32 is no greater than
the distance between first edge 22 and second fold line 52.
Thus, it can be seen that a simple and inexpensive to manufacture
pull-out tab envelope and a blank for making the same have been
disclosed by reference to presently preferred embodiments, which
envelope has a particular use as a promotional item. Having now
described illustrative and preferred embodiments of the present
invention in sufficient detail to permit a complete understanding
of the various aspects of the invention, it should be apparent to
those reading this specification that the objects set forth at the
outset hereof have been successfully achieved. Modifications and
variations may be made without departing from the invention.
For example, to prevent any possibility of anyone deliberately or
surreptitiously seeing the "secret" message, winning number,
indicia, etc, via the die cut slit 42 or windows 58 while the
envelope is still sealed, it should be recognized as an integral
variation of this invention that the second panel 14, which is
pulled out when the tab 56 is lifted, detached and pulled, may be
printed with the desired "message" on the reverse side, namely the
side opposite the pull tab when the envelope is sealed closed and
ready to be opened. The die cut window(s), therefore, may be placed
on the half of the first panel 12 between folds 52 and 50.
Also, a window may be die cut in the second panel 14 which will
reveal the printed "message" on panel 12 through the die cut
window(s) on the first panel after the tab 56 is detached and
pulled.
