[0001] The present invention generally relates to foldable paper and, more particularly,
to printed matter, uniquely foldable to form an envelope for mailing purposes.
[0002] With the advent of computer print-outs, statements to customers are automatically
printed out by the computer's printer for mailing to customers. These statements,
in addition to the customer's name and address, contain pertinent information, which,
typically, customers wish to have maintained in confidence In cases where a remittance
has to be sent back by the customer a separate card or stub is printed out, which
contains machine-readable data and which the customer is asked to send back with his
(or her) remittance.
[0003] To simplify the printing operation it is desirable to perform all the printing on
one side of the sheet of paper. Furthermore, the operation could be enhanced if both
the statement and the remittance card were printed on the same side of a single sheet.
The task of mailing would be enhanced greatly if after all the required information
is printed, the sheet could serve as a secure envelope, thus dispensing with the need
for separate envelopes, which have to be stuffed and addressed.
[0004] None of the arrangements, used to date, provide all of these advantages, namely a
single sheet of paper on which a statement is printed, sometimes together with a remittance
card or stub on only one side of the paper, and which can be used to form a secure
envelope for direct mailing to a customer. As used herein a secure envelope intends
to refer to an envelope, sealed in a way that the contents thereof is not readily
available, except by opening the sealed envelope.
[0005] Briefly, the present invention comprises:
a single sheet of paper on which the name and address of the customer as well as all
data or information to be sent to him are adapted to be printed on one side of said
sheet, with the customer's name and address on a top portion of said sheet, further
including first through n successive sheet portions of substantially equal dimensions
extending from said top portion, n being an integer not less than 2, said n portions
being separated by folds so as to be foldable over one another with opposite edges
on the front side of said first and one of the other portions being securable to one
another, to form an envelope-like unit, substantially equal in size to said first
portion, said top portion which is adapted to contain the customer's address being
foldable onto the back side of said first portion to form at least a portion of the
front side of said envelope with the back side of said second portion forming the
envelope back side; and
means along at least the edges on the front side of said first portion for securing
the other portions thereto to form a sealed envelope.
The novel features of the invention are set forth with particularity in the appended
claims. The invention will best be understood from the following description when
read in conjunction with the accompanying drawings.
[0006]

Figure 6 is another folded view of the sheet with more than two basic portions; and
Figure 7 is a top view of the sheet useful in explaining another embodiment of the
invention.
[0007] Attention is first directed to Figures 1, 2A, 2B and 3 in connection with which a
basic embodiment of the invention will first be described. Briefly, the invention
comprises a single sheet of paper 10 on which all information is printed on its front
side or face, generally designated by 10f, while its back side or face will be referred
to as 10b. The width of the sheet is designated by W, while its length is designated
by L. In the particular embodiment the sheet 10 is folded along its width by a plurality
of folds, such as those designated by dashed lines 12 and 13, thus effectively dividing
the sheet into three sections or portions. They include a top portion 15, a first
portion 16 which extends downwardly from portion 15 and a second portion 17 which
extends from portion 16. As will become apparent from the following description, top
portion 15 serves at least as part of the front face of the envelope to be formed
while portions 16 and 17 serve as the envelope sides or walls.
[0008] During printing, only unclassified or information which is not to be kept secret
is printed on the top portion 15. Such information may consist of the customer's name,
e.g. John Doe, and his address. However as to portions 16 and 17, thereon and only
on their front faces 10f pertinent classified information, such as a bank statement
or the like, is printed. Such printed information is designated by dashed lines 20.
Preferably, for purposes to be explained the printing is not performed over the entire
width W of the sheet. Rather margins of widths w are provided from edges 10el and
10e2 of each of portions 16 and 17.
[0009] After all the information is printed on the front face of sheet 10, its folding and
other steps to convert it to an envelope are performed. A particular sequence of steps
will be described, althouth as will become apparent the sequence may be changed without
departing from the true spirit of the invention. Briefly, adhesive matter 22 is applied
to the margin areas w along the two opposite edges 10el and 10e2 of one or both of
the sheet portions 16 and 17. Then portions 16 and 17 are folded onto one another,
as shown in Figs. 2A and 2B. Thus any printed information is enclosed between the
two sheet portions. The adhesive matter 22, e.g. a thin layer of quick drying glue
may be used to glue the two portions to one another.
[0010] As to the top portion 15 adhesive matter 22 is applied either to its back face and/or
to the top of the back face of portion 16, so that as the latter mentioned portions
are folded onto one another, as shown in Figs. 2A and 2B, the top portion 15 becomes
glued onto the back face of portion 16.
[0011] After being folded and the various portions glued to one another the sheet 10 effectively
becomes an envelope 25, as shown in Fig. 3. Its length is equal to the paper width
W and its height H equals the height of portion 16 which is generally equal but not
less than the height of portion 17. As to top portion 15 it forms at least part of
the front face of the envelope and contains the addressee's name, e.g. John Doe and/or
the address, both of which have been printed out automatically by a computer printer
on the front face 10f of sheet 10, on which all other information was printed.
[0012] As shown in Fig. 3 the top portion 15 forms only part of the envelope front face.
This is done to save paper, by using part of the back face of portion 16 as the rest
of the envelope front face. In such an embodiment a stamp 26, which is generally of
the machine printable type, is applied to the back face of portion 16 of the paper
10 either before the printing, folding and glueing operation or thereafter. However,
if desired, top portion 15 may be long or high enough to form the entire envelope
front face. In such a case the step 26 could be applied automatically at an appropriate
corner on the front face 10f of top portion 15.
[0013] From the foregoing, it should thus be apparent that the single sheet of paper 10,
once information 20 is printed thereon on the front face thereof, e.g. 10f, it is
foldable and together with adhesive matter 22 is converted into envelope 25 (Fig.
3). The envelope need not be addressed since the addressee and/or his address were
already automatically printed on the paper top portion 15 which becomes at least part
of the envelope front face.
[0014] The fold 13 between the first portion 16 which is below the top portion 15 and the
following portion 17, forms a sealed top of the envelope. As to the envelope bottom
end, as described so far, it is open. However, the edges of the envelope 25 are sealed
by the glue 22 which secures portions 16 and 17 to one another. Thus, the information
20 is relatively secured. The envelope can be. opened by prying the edges of portions
16 and 17 apart. To facilitate such opening, at some point in the operation, preferably
after the envelope 25 is formed, rows of perforations 30 are formed near the opposite
edges of the envelope spaced distances w therefrom. Thus, by tearing off the envelope
edges along the perforations the glued areas of portions 16 and 17 are removed. As
a result, the addressee can unfold the two portions 16 and 17 and read the classified
information contained therein.
[0015] To fully secure the envelope it may be desirable to seal the bottom end of the envelope.
This can be achieved by applying a thin layer of glue along the bottom edge of paper
portion 17 and/or along the top end of portion 16, below fold 12, so that when these
edges are pressed against one another they adhere to one another.
[0016] In another embodiment, at some point during operation, preferably after all printing
has taken place, but before the top portion 15 is folded and glued to the back of
paper portion 16, an elongated U-shaped slot 35 is punched near the bottom of the
top portion 15, as shown in Fig. 1, so that the fold 12 represents the open end of
the slot, thus forming a flap 40. Adhesive matter such as a layer of glue 22 is applied
to the flap. After the folding operation is completed, the flap 40 is folded in a
direction opposite to that of the folding of the rest of the top portion 15. It is
pressed against the back of paper portion 17 near its outer edge as shown in Fig.
4, wherein the thicknesses of the various paper portions have been exaggerated for
explanatory purposes. Thus, by sealing the flap 40 against portion 17 the bottom end
is practically sealed. This prevents anyone from having access to the envelope content,
without cutting off the flap 40 and tearing the envelope edges along the perforations
30. The envelope with such a flap is shown in front view in Fig. 5. Actually Fig.
4 is a cross-sectional view of the envelope of Fig. 5 along lines 4-4.
[0017] Herebefore the invention has been described in connection with a sheet 10, foldable
into a secure envelope, which, in addition to the top portion 15, includes only two
additional portions 16 and 17 on which information 20 is printed to be mailed toa
customer. Clearly, if desired or necessary, due to the length of the statement the
sheet, except for top section 15, may consist and be folded into more than two portions,
generally referred to as n, where n is an integer. Herebefore n was equal to 2. The
n sheet portions are folded so that when n is greater than 2, e.g. 3, all the sheets,
except for the first and second, counting down from the top portion 15, are folded
between the first and second portions 16 and 17 to be sealed therebetween. Fig. 6
is a simple example in which the sheet is folded to include, in addition to the top
portion 15 and portions 16 and 17, a third portion 18 which extends from portion 17.
When folded, it is located between portions 16 and 17, as shown.
[0018] As previously pointed out, quite often when a statement is sent to a customer from
an entity, e.g. a bank or credit institution, a stub or card are enclosed, indicating
any remittance which may be due. Typically, the customer is asked to return the amount
due together with the card. The card typically includes machine-readable data and
other information, e.g. customer account for machine processing the remitted sum when
returned with the card. To facilitate the processing of such cards by a machine the
cards are designed with one or more sharp edges so that the cards can be properly
stacked and fed automatically through a card reader or the like.
[0019] In accordance with the present invention the need for such a separate card is totally
eliminated, thus further pointing out the significant advantages provided by the invention.
This aspect may best be explained in connection with Fig. 7 in which elements like
those previously described are designated by like numerals. Basically Fig. 7 is similar
to Fig. 1, except that a card-like portion 45, hereafter referred to as the card 45
extends from the last portion, e.g. portion 17. Initially it is an integral part of
sheet 10. All the information, typically printed on a conventional card is also printed
on card 45. In Fig. 7 numeral 47 designates dashed lines which represent such information,
which is often machine-readable. All such printing can be and, in accordance with
the present invention, is done at the same time the statement information, represented
by numeral 20 is done. Before the sheet is to be folded a row of perforations, represented
by numeral 48 is formed along the top of card 45 and the bottom end of portion 17.
Then a fold is formed therealong. Prior to forming perforations 48 or thereafter,
the card is cut so that its length designated X is preferably sligyhtly less than
the distance between perforations 30. That is (W-2w)> X. The card is also cut to have
one and preferably two sharp edges such as 51 and 52 forming an angle a typically
of 90°. These sharp edges are often required to facilitate the processing of the card
45 by a machine, when returned to the addressor.
[0020] Thereafter the card is folded between portions 16 and 17 and the rest of the sheet
is folded and sealed to form the secured envelope, as herebefore described. When the
envelope is received and opened by tearing off its edges along perforations 30 and
flap 40 the sheet is unfolded, thus revealing the statement information on portions
16 and 17 as well as the card. It should be stressed that since the glue 22 is beyond
perforations 30 the card's edges are never marred by glue, nor are they affected by
tearing off the envelope's edges since X<(W-2w). The card 45 is easily detachable
from the rest of the sheet, which the customer keeps, by detaching it along perforations
48. As long as edges 51 and/or 52 are unmarred the card can be machine processed when
returned to the addressor. It should thus be apparent that in accordance with the
present invention the single sheet 10 on which all matter is printable on one side
is foldable and securable to form, not only a secure envelope, but also include a
returnable card as an integral part thereof.
