[0001] This invention relates to a mailer form suitable for printing and a method of developing
the same and, more particularly, a single message-ply mailer form advantageously employed
in printing as by laser printing, ink jet printing, etc.
[0002] There is a need for a mailer form in business systems and promotional applications
that can be used with non impact and particularly laser type computer printers.
[0003] The mailer forms exemplified by my earlier patents are all designed for impact type
computer printers where an image produced on an outside office ply also makes an image
on the face of the mailer envelope and on plies already inside the mailer envelope.
These mailers are not suited for use with non impact computer printers or where an
original computer printed image is desired on the message copy of the mailer.
[0004] The mailers that are subject of this invention are computer printed where they are
essentially in the form of a single ply. This ply is then folded and glued in a way
that will achieve several important objectives:
[0005] First, the mailer can be a single ply form without the need for die cut windows,
window patching or glue patterns. This results in a low cost, easy to manufacture
mailer.
[0006] Second, the absence of exposed glue patterns, rough edges of a window die cut, and
loose edges of window patches results in a form that gives trouble free feeding and
printing, particularly on laser printers.
[0007] The face of the envelope, back of the envelope, message area and even the flap are
in position to receive computer print-out information. After folding, all the message
areas are protected from handling wear and tear and for security of the information
by portions of the mailer that are later to be discarded by the recipient.
[0008] Third, after computer print-out, the mailer can be folded conveniently on readily
available paper folder thus avoiding the need for specialized equipment.
[0009] Fourth, the mailer is held in the folded condition for mailing by simple glue lines
that are applied on the folder. It is also possible to provide glue patterns on the
mailer form initially and to activate these glue patterns by means of moisture, heat
or pressure.
[0010] Fifth, the folded mailer completely encloses the message portion so that it is secure
from prying eyes.
[0011] Sixth, the folded mailer is easily opened by the recipient by removing a perforated
stub at each end. It is also easy to remove and dispose of the non message portions
of the mailer that are to be discarded.
[0012] The inventive mailer includes a flap panel, a face of the mailer panel, a back of
the mailer panel, a message portion including one or more panels and two stub end
portions. The single ply form can be printed and is perforated both horizontally and
vertically before the form is computer printed. An interior cross perforation may
be provided to facilitate the eventual separation of the message panels from the other
portions which are to be discarded by the recipient. A vertical perforation near each
side enables the recipient to remove the two end stubs in order to open the mailer.
The invention in preferred embodiments, also provides an advantageous return envelope
construction. Other objects and advantages of the invention may be seen in the details
of the ensuing specification.
[0013] The invention will now be further described by way of example with reference to the
accompanying drawings, in which:-

[0014] In the illustrations given and with reference first to FIG. 1, the numeral 10 designates
generally a mailer suitable for laser printing and the like which is constructed according
to the teachings of this invention. The mailer 10 is a unitary paper sheet and is
equipped with a plurality of fold lines dividing the sheet into four panels. The uppermost
panel 11 ultimately becomes the flap of the mailer when it is sent out to the recipient.
[0015] Positioned immediately therebelow (in the illustration given) is the panel 12 which
becomes the face of the mailer, i.e., the portion to be equipped with the addressee
information. This normally varies from mailer to mailer.
[0016] Still proceeding downwardly in FIG. 1, the panel designated 13 ultimately becomes
the back of the mailer when it is being sent out. The back of the mailer 13 and flap
11 are available for computer variable information such as customer account number,
return address, promotional message, etc. Lastly, the bottom panel 14 will become
the message panel on which other variable information will be printed -- this along
with the panel 12 which is the face of the mailer and it will be seen that the information
to be imprinted thereon will occur on the same face of both panels 12 and 14.
[0017] The mailer as illustrated in FIG. 1 has two side edge portions 15 and 16 respectively
and adjacent to but slightly inboard thereof are lines of perforation as at 17 and
18 defining tear off stubs 19 and 20.
[0018] Extending perpendicularly to the lines of perforation 17 and 18 are a plurality of
transversely extending fold lines as at 21, 22 and 23. Fold lines 21 and 22 define
the mailer face panel 12. Fold lines 22 and 23 define the mailer back panel 13. Fold
line 23 with the sheet edge 24 define the message panel 14, and fold line 21 along
with sheet edge 25 define the flap panel 11.
Operation Generally
[0019] The sheet 10 can be processed through a computer printer either in discreet form
as shown or as part of a continuous web, with transverse separation occurring thereafter.
In any event, the mailer 10 is normally computer imprinted in the panels 12 and 14
with variable information relating to the addressee and the particular message, respectively.
Other panels are also available for computer imprinting.
[0020] After computer printout, the mailer is folded as illustrated in FIG. 1A. Referring
now to FIG. 1A, the message panel 14 is seen in the central portion of that figure
and is defined at one edge by the fold line 23. Positioned under the message panel
14 is the mailer back panel 13 -- by folding along the fold line 23. Thereafter, the
face 12 of the mailer is positioned over the message panel 14 by folding around the
fold line 22. Lastly, the flap 11 is positioned over the mailer back panel 13 by folding
around the fold line 21.
[0021] Incident to this folding, adhesive is advantageously applied to the front face of
the tear off stubs 19 and 20 as at 26 and 27 in FIG. 1. This results in the front
face of the message panel 14 being adhered along its sides to the rear face of the
front panel 12 as at 26A and 27A. It also results in the flap panel 11 being adhered
to the back of the mailer as at 26B and 27B.
[0022] When the mailer is received by the recipient all he or she has to do is to tear off
the two tear off stubs 19 and 20 whereupon the mailer can be unfolded. Normally, I
provide a line of perforation along the fold line 23 so as to permit the message panel
to be readily separated from the remainder of the mailer. This is particularly advantageous
when a return envelope is provided within the mailer as can be seen in FIG. 2.
[0023] In FIG. 2, the numerals designating parts identical to those in FIG. 1 are given
the same numeral but with the addition of 100. Hence, the flap panel is 111, the mailer
front 112, the back 113 and the message panel 114. In like fashion, the tear off stubs
are 119 and 120. Further, both the fold lines 122 and 123 include lines of perforation
which permit not only detachment of the message panel 114 from the mailer back 113
but also detachment of the face of the mailer 112 from the back of the mailer 113.
This results in the provision of the return envelope generally designated 128 (see
also FIG. 2A).
[0024] The return envelope 128 is developed by using a patch or ply of paper secured to
the rear or second face of the mailer, i.e., the side opposite to that receiving the
computer printing. This advantageously is positioned between the stub foming perforations
117 and 118 and consists of two portions. The first portion 129 is secured to the
back panel 113 by gluing along three sides as at 130, 131, and 132. The second portion
133 is not adhesively secured but underlies the mailer front 112 and is provided with
a line of potential folding as at 134. Thus, it is possible for the recipient to return
the message panel 114 by only folding the same once.
[0025] In use, the recipient detaches the return envelope which includes the mailer back
113 and the two portions 129 and 133 from the remainder of the mailer -- by tearing
along the lines of perforation 122 and 123. After insertion of the message panel 114,
check, or other information piece, the return envelope 128 is closed by folding along
the line 134 using adhesive that has been previously applied as at 135. This may be
of the remoistable variety and the return envelope is now ready for mailing.
[0026] Two variations of the return envelope are available as presented in FIGS. 2B and
2C. In FIG. 2B a return envelope 128′ is provided which is again attached to the back
panel but with the glue line 131′ reoriented so that when the mailer is processed
through the computer in the direction of the arrow applied to FIG. 2B, there will
be no possibility of the flap part 133′ being caught.
[0027] In FIG. 2B, I have employed a single transverse line as at 121 to represent a fold
line and a double transverse line as at 134 to represent a perforation line with strong
bonds so that it is readily folded but not too easily broken. The third form of designation
is a double line with a slash across as at 122 and 123 to indicate a line of perforation
with very weak bonds so that separation is easily achieved.
[0028] In some instances, it may be advantageous to have the return envelope of the same
length as the mailer, i.e., coextensive therewith and this is illustrated at 128˝
in FIG. 2C. This again is secured to the rear panel 113 by means of a line of transverse
glue as at 131˝. I provide another line of perforation with weak bonds as at 136 for
easy detachment of a portion of the second web -- which provides the return envelope
-- but which is not needed when the return envelope is used. This additional portion
137 seen at the extreme right of FIG. 2C may carry advertising information, instructions,
or the like.
[0029] Turning now to FIG. 3, a mailer form generally designated 210 is provided which is
identical in most respects to that seen in FIG. 1 -- but with the exception of providing
an additional message panel 238. The first and second message panels 214 and 238 are
adapted to be separated from the remainder of the mailer by detachment along the line
of perforation 223. This then provides the recipient with panels 214 and 238 which
are separated by a fold line 239.
[0030] With the construction of FIG. 3, two folding configurations are available. In FIG.
3A I illustrate what could be considered a "continuous rollover" fold -- where the
mailer is essentially folded on itself as one would wind an element.
[0031] The other folding configuration is illustrated in FIG. 3B which embodies a form of
"zig-zag" folding. In FIG. 3B, the message panel 238 is on top of the first message
panel 214. Below the panel 214 is the back panel 213. Completing the mailer assembly
is the front panel 212 and the flap 211.
[0032] In FIG. 3A, the second or bottom-most message panel 238 underlies the first message
panel 214 after which the configuration is the same.
[0033] In FIG. 4 I illustrate a mailer 310 which has three message panels 314, 338 and 340.
The line 323 separating the first message panel from the mailer back is advantageously
a line of perforation whereas the line 339 between the first and second message panels
314 and 338 is a fold line -- as is the line 341 between the second and third message
panels 338 and 340.
[0034] With three message panels, three folding variations are possible and these are illustrated
in FIGS. 4A, 4B and 4C.
[0035] In FIG. 4A, the continuous rollover form characteristic of FIG. 3A is employed on
the message panels.
[0036] In FIG. 4B, a combination of the rollover and zig-zag procedure is employed whereas
in FIG. 4C the folding is of the zig-zag type on the message panels.
[0037] In the version of the invention presented in FIG. 5, I am able to provide two message
panels. In the illustration given in FIG. 5 the face of the mailer is designated 412
and proceeding downwardly first and second flap portions 411 and 411′ are next encountered.
The fourth panel down is designated by the numeral 413 and is available for a message
imprinting, the same as is the back panel 414. Thus, I am able to use the mailerback
panel as a second message panel.
[0038] By the provision of two intermediate flap panels 411 and 411′, I am able to provide
the two message panels 413 and 414 while still achieving a confinement or enclosing
of the message panels within the mailer. This can be appreciated from a consideration
of FIG. 5A. There it will be seen that the rear of the message panel 414 now becomes
the back of the folded mailer and next in proceeding downwardly is the message panel
413. The message panels 413 and 414 are separated by a fold line 423 which can also
be seen in FIG. 5. The message panel 413 is also defined by a fold line 422 which
is adjacent the flap 411′. The flaps 411 and 411′ are folded on themselves as can
be appreciated from the left hand portion of FIG. 5A and folded behind the two message
panels 413 and 414. The face panel 412 is folded under the message panel 413. The
face panel 412 is defined in part by the fold line 421.
[0039] Again, the unitary sheet is equipped with lines of perforation 417 and 418 adjacent
the longitudinal edges 415 and 416 respectively. This develops the tear off stubs
419 and 420.
[0040] Adhesive is provided as at 426a and 427a analogous to that found in the embodiment
of FIG. 1. However, the portion of the glue stripe at 426b and 427b is positioned
differently from that in FIG. 1, being on the front face of the second flap 411′.
[0041] By reference to FIG. 5A, it will be seen that the first glue line 427a is effective
to adhere together the sides of the message panels 414 and 413. Then, by virtue of
the glue provided at 427b, the flap 411′ is adapted to be secured to the unprinted
face of the second messge panel 411. The sides of the front panel 412 -- in the stub
portion -- are secured to the remainder of the mailer by the adhesive 426a and 427a
extending through the holes 442 in the first message panel 413.
[0042] In FIG. 5B I show a modified form of the mailer 410 which includes a return envelope
428. This showing is analogous to that found in FIG. 2B.
[0043] While in the foregoing specification a detailed description of an embodiment of the
