## Background
REFERENCE TO RELATED APPLICATIONS
This application claims the benefit of U.S. Provisional application Ser. No. 60/668,662, filed Apr. 5, 2005, entitled, “REUSABLE ENVELOPE STRUCTURES AND METHODS,” which application is incorporated herein by reference in its entirety for all purposes.


TECHNICAL FIELD
The present invention is directed to reusable envelope structures. More particularly, the present invention is directed to reusable envelope structures that provide additional functions such as for advertising, promotion of goods and services, or general correspondence, for example.
BACKGROUND
One well-known type of envelope structure is a bangtail envelope. A bangtail envelope structure includes a flap or tail that is either removably attached to a closure flap of the envelope or a separate flap distinct from the closure flap of the envelope. In either case, the flap is designed so that it needs to be detached from the envelope in order to close the envelope with the closure flap. One application for such bangtail envelope structures is for return envelopes. Typically, return envelopes are used in a first mailed envelope for commercial activities such as the payment of bills, or the ordering of merchandise, or the like. For this type of use, the bangtail flap is generally sized to be larger than the closure flap, and can take the form of a return slip, coupon, or detachable order form, or it may simply be used as an advertising or promotion attachment to the return envelope. Upon receipt, the recipient can detach the bangtail flap and discard it, or use it as a part of the materials included in the return envelope.
SUMMARY
The present invention provides reusable envelope structures that can also provide advertising, feedback, billing, promotional, or other correspondence or bangtail-like functionality. The present invention also provides methods of using and methods of making such envelopes. In preferred aspects, the present invention provides envelope structures in which a single envelope structure can provide multiple uses.
A reusable envelope structure in accordance with the present invention comprises a reusable flap and a removable portion. The removable portion may comprise, for instance, a coupon or similar advertising, promotional, or correspondence device. In practical use, an envelope in accordance with the present invention is designed so that the envelope can be closed a first time by the reusable flap. Removal of the removable portion helps to open the envelope a first time by the reusable flap. When closed, a portion of the reusable flap is sealingly attached to the removable portion and also detaches when the portion of the reusable flap is removed when opening the envelope a first time. A remaining portion of the reusable flap can then be sealingly attached to the envelope to close the envelope a second time for reusing the envelope.
Accordingly, in one aspect of the present invention, a reusable envelope is provided. Generally, the envelope comprises an envelope body and a reusable sealing flap. The envelope body comprises at least first and second oppositely facing body panels. The first body panel comprises a removable portion capable of being separated from the first body panel. The removable portion is preferably defined by at least one line of weakness such as a perforation or the like. The reusable sealing flap comprises first and second flap portions separable from each other. Preferably, the first and second flap portions are separable along at least one line of weakness. The first flap portion is foldably attached to the second body panel of the envelope body and extends along a length of the second body panel of the envelope body. The second flap portion extends from the first flap portion and extends along a length of the first flap portion. The second flap portion is designed to be capable of being attached to the removable portion of the first body panel to close the envelope body a first time. In accordance with the present invention, the removable portion of the first body panel can be separated from the first body panel and the second flap portion can be separated from the first flap portion while attached to each other to help open the envelope body after being closed the first time. The first portion of the envelope can subsequently be used to close the envelope body a second time.
In another aspect of the present invention a method for reusing an envelope is provided. The method comprises providing an envelope having an envelope body comprising at least first and second oppositely facing body panels. The first body panel comprises a removable portion capable of being separated from the first body panel such as by a first line of weakness, for example. The first body panel also comprises a reusable sealing flap comprising first and second flap portions separable from each other such as along a second line of weakness, for example. The first flap portion is foldably attached to the second body panel of the envelope body and extends along a length of the second body panel of the envelope body. The second flap portion extends from the first flap portion and extends along a length of the first flap portion. The method also comprises attaching the second portion of the sealing flap to the envelope body to close the envelope body a first time, opening the envelope body by separating the removable portion of the first body panel from the first body panel and separating the second flap portion from the first flap portion while attached to each other, and attaching the first portion of the sealing flap to the envelope body to close the envelope a second time.
In another aspect of the present invention, a method of delivering a marketing device to a consumer is provided. The method comprises structurally integrating the marketing device with a reusable envelope so that separating the marketing device from the reusable envelope after the reusable envelope has been closed with an envelope flap a first time functions to open the reusable envelope at the envelope flap in a way that allows the envelope flap to be used to close the envelope a second time. The method also comprises sending the envelope to a consumer.
In yet another aspect of the present invention, a reusable envelope is provided. The reusable envelope comprises an envelope body and a reusable flap. The envelope body has a body panel and a removable panel attached to the body panel of the envelope body. The reusable flap comprises a first flap portion removably attached to a second flap portion. The first flap portion comprises a first adhesive region that sealingly mates with the removable panel to close the envelope body. The first flap portion and the removable panel can be detached from the body panel of the envelope body together to open the envelope. The second flap portion comprises a second adhesive region allowing the second flap to sealingly mate with a surface of the body panel of the envelope body after the first flap portion and the removable panel are detached from the body panel of the envelope body to close the envelope body an additional time.

DETAILED DESCRIPTION
Referring to FIGS. 1 and 2, an exemplary envelope 10 in accordance with the present invention is shown. Generally, the envelope 10 comprises an envelope body 12 and a reusable flap 14. The envelope body 12 comprises first and second oppositely facing panels, 16 and 18, that define an interior space 11 of the envelope body 12. The first panel 16 of the envelope body 12 comprises a removable portion 20 that is described in more detail below. Preferably, the second panel 18 of the envelope body 12 comprises a window 22, as can be seen in FIG. 2, which can be used to display a mailing address that is provided on correspondence located in the interior space of the envelope body 12. Optionally, such a window can be provided in the first panel 16 or both the first and second panels, 16 and 18, if desired. An envelope in accordance with the present invention, such as the envelope 10, can be addressed in any manner. For example, an address can be provided directly on the second panel 18 or indirectly by using well-known address labels or the like. Also, addressing techniques that use tear off portions as disclosed in Applicant's co-pending Non-Provisional U.S. patent application filed on Jul. 31, 2003 having Ser. No. 10/632,489 and entitled “Environmentally Friendly Reusable Envelope Structures” can be used. The disclosure of U.S. patent application Ser. No. 10/632,489 is fully incorporated by reference herein for all purposes.
The reusable flap 14 preferably comprises first and second flap portions, 24 and 26, that are designed to enable the envelope 10 to be reused one or more times. The first and second flap portions, 24 and 26, are separable from each other along a line of weakness, generally illustrated with a dashed line identified by reference numeral 28. Any presently known or future developed line of weakness capable of functioning to separate the first and second flap portions, 24 and 26, from each other can be used such as a single perforation line, a plurality of spaced perforation lines, a tear strip, a crease or fold line that provides a mechanical weakening, or the like. Also, the first and second flap portions, 24 and 26, preferably comprise separate adhesive regions, 30 and 32, respectively, that can be used to seal the first and second flap portions, 24 and 26, to the first panel 16 of the envelope body 12 for first and second uses of the envelope 10 as described further below. Adhesive regions, 30 and 32, are not required and any way of functionally closing the envelope 10 for mailing can be used.
The first flap portion 24 is foldably attached to the second panel 18 of the envelope body 12 along a fold line 25 and preferably extends along the entire length of the second panel 18, as illustrated. However, the first flap portion 24 is not required to extend along the entire length of the second panel 18 and may extend along any desired length of the second panel 18. The second flap portion 26 extends from the first flap portion 24, as shown. The second flap portion 26 preferably extends along the first flap portion 24 for a length less than the first flap portion 24 but can extend along the first flap portion 24 for any desired length including the entire length of the first flap portion 24. Other reusable flaps that can be used for the reusable flap 14 in accordance with the present invention are described in Applicant's co-pending Non-Provisional U.S. patent application filed on Jul. 31, 2003 having Ser. No. 10/632,489 and entitled “Environmentally Friendly Reusable Envelope Structures” and Applicant's co-pending Non-Provisional U.S. patent application filed on Feb. 24, 2005 having Ser. No. 11/064,791 and entitled “Reusable Envelope Structures and Methods.” The disclosures of U.S. patent applications having Ser. Nos. 10/632,489 and 11/064,791 are each fully incorporated by reference herein for all purposes.
The removable portion 20 is preferably designed so that the removable portion 20 can be completely separated from the first panel 16 of the envelope body 12 in a way that does not affect the ability of the envelope 10 to function as a mailing device (for a return trip, for example). As illustrated, the first panel 16 includes lines of weakness, 34, 35, 36, and 37, that define the removable portion 20. The lines of weakness, 34, 35, 36, and 37, preferably comprise perforation lines but any line of weakness can be used as noted above with respect to the reusable flap 14. The removable portion 20 can have any desired shape and can be defined by any number of lines of weakness. Also, as illustrated, the removable portion 20 preferably comprises a tab 38 that is designed to help in separating the removable portion 20 from the first panel 16 of the envelope body 12. The tab 38 may comprise a precut region that can be grasped and pulled to help separate the removable portion 20 from the first panel 16 of the envelope body 12. Any number of tabs or similar regions may be used in any location for the purpose of helping to remove the removable portion 20.
In accordance with the present invention, the removable portion 20 preferably comprises information such as that used for advertising, marketing, promotions, product ordering, bill paying and the like. Particularly, the removable portion 20 can comprise any correspondence used with conventionally known bangtail type envelopes or the like. For example the removable portion 20 may comprise a return slip, coupon, detachable order form, or other similar correspondence.
The removable portion 20 is designed so that the removable portion 20 can function to help open the envelope 10 after the envelope 10 has been closed a first time with the reusable flap 14. Referring to FIG. 3, the envelope 10 is shown as closed by the second flap portion 26 of the reusable flap 14 such as by using the adhesive region 32. As shown, the second flap portion 26 is sealingly attached to the removable portion 20. Preferably, when in this configuration, the line of weakness 28 of the reusable flap 14 and the line of weakness 34 of the removable portion 20 substantially overlap. This allows the second flap portion 26 to be separated from the first flap portion along the line of weakness 29 at the same time as the removable portion 20 is separated from the first panel 16 along the line of weakness 34 as shown in FIG. 4. After the envelope 10 is opened in this manner, the envelope 10 can be reused with the first flap portion 24.
In one preferred aspect of the present invention, the line of weakness 34 can be precut and does not need to be a line of weakness such as a perforation. That is, the removable portion 20 can be attached to the first panel 16 by perforations at the lines of weakness 35, 36, and 37 and the removable portion 20 can be pre-separated from the first panel 16 along the line of weakness 34. This can make it easier to remove the removable portion 20 and the second flap portion 26 together for opening the envelope 10 a first time.
Further referring to FIG. 4, removal of the removable portion 20 preferably reveals a backing panel 40. The backing panel may comprise any desired information such as a return address or information such as can be provided on the removable portion 20 as noted above, for example. The first panel 16 of the envelope body 12 and the removable portion 20 can be designed in any desired way to provide the backing panel 40 when the removable portion is removed. For example, the removable portion 20 can be defined in the first panel 16 and the backing panel 40 can be attached to an inside surface of the first panel 16 of the envelope body 12. Alternatively, the removable portion 20 can be defined in a panel that is attached to an outside surface of the first panel 16 of the envelope body 12. In this way, the first panel functionally provides the backing panel 40. It is contemplated however, that the backing panel 40 does not need to be used and contents of the envelope 10 can function as the backing panel 40.
In FIG. 5, another exemplary reusable envelope 50 in accordance with the present invention is shown. The envelope 50 is preferably similar to the envelope 10 discussed above and preferably comprises a body 52 and a reusable flap 54, as illustrated. The body 52 comprises first and second panels, 56 and 58, respectively. Also, the reusable flap 54, as shown, comprises first and second flap portions, 60 and 62, respectively. In accordance with the present invention, the first panel 56 comprises a removable portion 64 (shown partially removed) that is defined by lines of weakness, 66 (separating the first and second flap portions), 68, 70, and 72 (shown as separated along line 72). The removable portion 64 comprises a fold portion 74 that is attached to the removable portion along fold line 76. The fold portion 74 can be attached to the removable portion 64 in other ways, however, such as by a line of weakness or with an adhesive, for example. In this way, the fold portion 74 can comprise information, such as private information, that is contained within the envelope body 52. The information can be any information as described above with respect to envelope 10.
