REUSABLE ENVELOPE
Abstract
An envelope includes a body portion with a window opening
covered by a transparent window patch. A pair of opposed side flaps
are integrally connected to the body portion and are demarcated
from the body portion by score lines along the edges of the body
portion. A top and bottom flap are integrally connected to the
upper and lower edges of the body portion respectively and are
demarcated therefrom by score lines along the body portion upper
and lower edges. The bottom flap is secured in overlying relation
to the folded side flaps to provide a first pocket for receiving an
insert. After the first mailing of the envelope, the upper portions
of each of the side flaps together with the top flap and an upper
portion of the body portion are severed from connection with the
remainder of the body portion and side flaps to form a second
pocket for receiving an insert. By securing the remaining top
portion of the body portion in overlying relation to the bottom
flap and the remaining portions of the side flaps, the envelope is
adapted for second mailing.

Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to envelopes and more particularly to
envelopes suitable for reuse after the first mailing by detaching
selected portions of the original envelope prior to the second
mailing.
2. Description of the Prior Art
Providing a second self-addressed envelope within a first envelope
submitted to the addressee by the sender for purposes of paying a
bill or receiving requested information by return mail in the
enclosed envelope is a common business practice. The cost of
manufacturing the enclosed or second envelope is an additional
expense that must be borne by the sender or passed on to the
customer in the form of higher prices. Furthermore, clerical
personnel are required to expend considerable time and effort in
completing the task of inserting the second envelope within the
first envelope to be mailed to the addressee. Once the addressee
receives the envelope from the sender, there exists the possibility
that the addressee will overlook the enclosed envelope and
subsequently dispose of it together with the first envelope.
Consequently, the effort and expense exerted by the sender in
providing the addressee with a second envelope for return mailing
is wasted. Also, the first envelope, once it is received and opened
by the addressee, is no longer usable and becomes a waste item
thereby presenting a disposal and litter problem.
Exemplary efforts to provide envelopes and mailing devices for
multiple use are illustrated and described in U.S. Pat. Nos.
3,522,908; 3,655,121 and 3,718,276. U.S. Pat. No. 3,522,908
discloses a two-compartment envelope comprising a plurality of
overlying panels which form a first large main compartment and a
second small compartment. Both compartments are provided with
openings located in overlying relation at the same end of the
composite envelope so that the closing flap secured to one of the
panels when folded closes both compartments. The small compartment
is intended to house a return envelope or a card. No provision is
made for severing the small compartment from the main compartment
so that it may be used separately of the composite envelope.
U.S. Pat. No. 3,655,121 illustrates and describes a combination
return address and receipt indicating answer card device. The card
is secured to a package or a letter by adhesive applied to one side
thereof. Initially the device is secured to a package or letter and
serves as a return address label for the sender. The device,
subsequently, functions as a reply card to be mailed by the
addressee to the sender as an acknowledgment of receipt. A
removable flap is provided to expose the upper portion of the stamp
receiving side of the card to leave the address receiving portion
exposed when the device is mailed as a reply card by the addressee
to the sender. However, the use of this card device is limited to
acknowledgment of receipt and contains no closure or pocket for
submitting any other information or bill payment to the sender.
U.S. Pat. No. 3,718,276 provides a combination envelope for use to
deliver processed photographic negatives and prints from the
processor to the customer. A first large envelope pocket is
provided to receive and hold prints for mailing and handling. A
second small envelope secured to the top edge of the front panel of
the first envelope is provided to retain the processed negatives.
The second small envelope may be severed from the first envelope,
however, it is not intended to be used for mailing negatives as no
provision is provided to secure the closure flap. Furthermore,
limited adhesive is provided for sealing the front panel to the
back panel, and as a result, one end of the second envelope remains
open to receive the negatives. There is need to provide a reusable
window-type envelope capable of manufacture by automatic envelope
making machines which permits one to correspond with the sender by
detaching selected portions of the first envelope so that it may be
reused by the addressee as an envelope for second mailing.
SUMMARY OF THE INVENTION
According to the present invention, there is provided an envelope
that includes a body portion having upper and lower edges and side
edges with a window opening provided adjacent the lower edge. A
pair of opposed side flaps is integrally connected to the body
portion. Each of the side flaps is demarcated from the body portion
by a score line along one of the body portion side edges. A bottom
flap is integrally connected to the body portion. The bottom flap
is demarcated from the body portion by a score line along the lower
edge. The bottom flap is secured in overlying relation to each of
the side flaps folded along the score line of the body portion side
edges by adhesive means. The side flaps folded in overlying
relation with the body portion thus form a first closure or pocket
for receiving inserts. A top flap is integrally connected to the
body portion and is demarcated from the body portion by a score
line along the body portion upper edge. The top flap is secured in
overlying relation to the side flaps and the body portion to
thereby seal the first closure. A portion of each of the side flaps
together with the top flap and the body portion upper edge is
severable from connection to the body portion to thereby form a
second closure or pocket for receiving inserts. The remaining top
portion of the body portion is secured in overlying relation with
the remaining portions of the side flaps and the bottom flap to
thereby seal the second closure by adhesive means for reuse of the
envelope. With this arrangement, the envelope used for first
mailing is easily adapted for reuse in second mailing.
Accordingly, the principal object of this invention is to provide a
reusable envelope in which the addressee can reply to the sender by
reusing the envelope submitted to him by the sender.
Another object of this invention is to alleviate the need of
supplying the addressee with a second enclosed envelope for
corresponding with the sender.
Another object of this invention is to provide a reusable envelope
that may be economically and efficiently manufactured by automatic
envelope making machines.
These and other objects and advantages of this invention will be
more completely disclosed and described in the following
specification, the accompanying drawings, and the appended
claims.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to the drawings and particularly FIG. 1, there is
illustrated an envelope or envelope blank generally designated by
the numeral 10 that includes a body portion 12 with a pair of
opposed outwardly turned side flaps 14 and 16 and a bottom flap 18
integrally connected to the body portion 12. A rectangular window
opening 20 provided in the body portion 12 includes a rectangular
window patch 22, manufactured from a transparent plastic material.
The window patch 22 is suitably secured to the window margin 24 on
the inner surface of the envelope blank 10 over the window opening
20. The opposed side flaps 14 and 16 are demarcated from the body
portion 12 by the score lines 26 and 28. A score line 30 extends
transversely across the bottom edge of the body portion 12 and
demarcates the body portion 12 from the bottom flap 18. A top flap
32 is integrally connected to the body portion 12 and is demarcated
therefrom by the score line 34 which entends transversely across
the upper edge of the body portion 12 parallel to the score line
30.
The side flaps 14 and 16 include upper end portions 36 and 38 each
having a side flap top edge 40. A tear facilitating perforated line
42 spaced a short distance below the top edge 40 extends
transversely across each of the side flaps 14 and 16. Tear
facilitating perforated portions 44 of the score lines 26 and 28
extend downwardly from the score line 34 along the side edges of
the body portion 12 and intersect the terminus of the perforated
lines 42 of the side flaps 14 and 16. A strip of gum or adhesive
46, having a predetermined thickness, is provided on the inner
surface of the top flap 32 adjacent the top flap upper edge 48. A
second strip of adhesive 50, having a predetermined thickness, is
provided transversely across the inner surface of the body portion
12 and positioned adjacent the score line 34. The top of the
adhesive strip 50 is defined by the tear facilitating perforated
line 52 also extending transversely across the body portion 12 and
laterally bound by the score lines 26 and 28. The bottom flap 18 is
also provided with strips of adhesive 54 and 56 provided on the
inner surface of the bottom flap 18 adjacent the diagonal edges 58
and 60.
The envelope 10 illustrated in FIG. 2 is assembled by folding the
side flap 14 along the score line 26 and the side flap 16 along the
score line 28 so that the side flaps 14 and 16 overlap the back of
the body portion 12. The bottom flap 18 is folded along the score
line 30 and positioned in overlying relation with the side flaps 14
and 16. The adhesive strips 54 and 56 secure the folded bottom flap
18 to the folded side flaps 14 and 16 and thereby provide an
envelope closure or pocket. The pocket is defined by the bottom
flap 18 positioned in overlying relation with portions of the body
portion 12 and the folded side flaps 14 and 16. The pocket has an
open end portion generally designated by the numeral 61.
An insert for first mailing is placed within the pocket open end
portion 61 and sealed therein by folding the top flap 32 along the
score line 34 and securing the top flap 32 in overlying relation to
the bottom flap 18 and the side flaps 14 and 16 by moistening the
adhesive strip 46 and applying pressure along the length thereof.
Thus, the envelope 10 containing the selected insert is ready for
first mailing as indicated in FIGS. 3 and 4. The address of the
addressee is visible through the window patch 22 covering the
window opening 20 in the body portion 12. The insert enclosed
within the envelope 10 and submitted to the addressee may be of the
type requesting the return to the sender certain information
desired by the sender or the payment of a debit note submitted to
the addressee by the sender.
Once the envelope is received by the addressee, he may comply with
the request of the sender by reusing the envelope for second
mailing to remit to the sender the desired information or payment
of the debit note. In order for the addressee to reuse the original
envelope used in the first mailing, he must remove that portion of
the body portion 12 upon which the stamp 64 and the return address
66 were provided, as indicated in FIG. 4. This is accomplished by
first severing the upper end portions 36 and 38 of the side flaps
14 and 16 from the body portion 12. The upper end portions 36 and
38 are detached by tearing the side flaps 14 and 16 along the
perforated lines 42 in a direction progressing outwardly from the
center of the body portion 12 toward the score lines 26 and 28.
Subsequently, the upper end portions 36 and 38 are removed from
connection with the side flaps 14 and 16. Then by tearing upwardly
from the free edge of upper end portions 36 and 38 along the
perforated portions 44 of the score lines 26 and 28 toward the top
flap 32, the upper end portions 36 and 38 are removed from
connection with the body portion 12.
The top flap 32 and the upper portion of the body portion 12 are
severed from connection with the body portion 12 by tearing along
the perforated line 52 transversely across the body portion 12. As
illustrated in FIG. 4, with the upper end portions 36 and 38
together with the top flap 32 and the upper portion of the body
portion 12 removed from connection with the side flaps 14 and 16
and the remainder of the body portion 12, the envelope 10 is
available to be reused for second mailing. The closure or pocket of
the envelope 10 for second mailing is reduced in size as compared
to the pocket of the original envelope by virtue of the removal of
portions of the original envelope. To provide a pocket having
sufficient capacity to house the selected insert, the original
envelope may be larger in dimension than normally required of
conventional business envelopes so that the envelope for second
mailing may adequately contain the insert.
The envelope 10 suitable for second mailing includes a newly formed
top flap 68 having an edge 70 formed as the result of tearing the
perforated line 52 across the body portion 12. The side flaps 14
and 16 are positioned in underlying relation with the bottom flap
18 as provided for the envelope 10 for the first mailing with the
modification of having the upper end portions 36 and 38 removed
from the side flaps 14 and 16. The closure or pocket of the
envelope 10 for second mailing is sealed by moistening the strip of
adhesive 50 and folding the top flap 68 to sealingly engage the
side flaps 14 and 16 and the bottom flap 18 as shown in FIG. 6 of
the drawings.
For the first mailing the address of the addressee is visible
through the window patch 22 covering the window opening 20,
however, for the second mailing, the sender's address is visible
through the window opening 20. The insert may be used for both the
first and second mailing by appropriately printing the address of
the sender, as well as the address of the addressee on the insert.
The insert is suitably placed in the pocket of the envelope 10 so
that the desired address for either the first or second mailing is
visible through the window patch 22 of the window opening 20. The
envelope 10 for second mailing has sufficient area above the window
opening 20 for placement thereon of a postage stamp and a return
address label. Accordingly, the hereinabove described invention
provides a useful and novel envelope which is adaptable for reuse
after first mailing thereby avoiding the additional expense of
supplying a second envelope for return mailing.
According to the provisions of the patent statutes, I have
explained the principle, preferred construction and mode of
operation of my invention and have illustrated and described what I
now consider to represent its best embodiments. However, I desire
to have it understood that, within the scope of the appended
claims, the invention may be practiced otherwise than as
specifically illustrated and described.
