Abstract
A reusable envelope includes a plurality of panels defining a pocket having an opening for receipt of the content material. The reusable envelope also includes a flap closure having first and second bond lines and first and second flap folds disposed between the bond lines. The first flap fold and first bond line are adapted to close the pocket during an initial mail delivery while the second flap fold and second bond line are adapted to close the pocket for reuse during a subsequent mail delivery. A tear strip is disposed between the front panel and the flap closure to open the pocket for removal of the mailpiece content material. Upon removal of the tear strip and insertion of content material associated with the subsequent mail delivery, the second bond line connects the panels to close the pocket for reuse of the envelope.
Description
- This application claims the benefit of U.S. Provisional Application Ser. No. 61/209,122, filed Jun. 10, 2009, (Docket No. G-515) entitled “Reusable Envelope Tear Off Front”
- The present invention relates to mailpiece envelopes, and, more particularly, to a new and useful reusable mailpiece envelope which facilitates assembly/use and is configured for ease of manufacture.
- In the spirit of reducing the environmental impact associated with fabricating mailpiece envelopes, i.e., the number of trees cut, transported and consumed, interest is increasing for mailpiece envelopes which can be used more than once. For example, in a typical billing process, a first envelope containing a bill/request for payment, is mailed to a recipient and, a second envelope, contained and delivered within the first, is used by the recipient to return payment. Hence, two (2) envelopes are consumed in a typical billing process. Inasmuch as this type of mail communication is perhaps the most common form of exchange, an envelope which can be used multiple times, offers a unique opportunity to lower the cost of mailing and save natural resources.
- Various attempts have been made to introduce a single envelope which may be reconfigured for reuse by the mail recipient. That is, envelopes have been designed which, after initial mailing, may be used again for return correspondence. In this specific instance, a single reusable envelope substitutes for two (2) or more envelopes, such as those required for bill/payment mail communications, discussed in the preceding paragraph.
- While the motivation to implement reusable envelopes is well-understood and appreciated, especially in view of the current environmental climate, difficulties associated with (i) alterations during delivery, (ii) damage to the envelope, (iii) ease of use, and/or (iv) high fabrication cost, have slowed the widespread acceptance of such envelopes. For example, when a mailpiece is delivered, automated handling equipment used by the United States Postal Service (USPS), scans the mailpiece to read a “pre-sort” or “preprinted’barcode”, i.e., a barcode indicative of the recipient's destination address and which is used for sorting batches of mail into route/delivery order sequence. Should the pre-sort barcode be absent from the mailpiece, a scanner reads the destination address (i.e., via Optical Character Recognition (OCR) program code) and a barcode representative of the destination address is printed on the face of the mailpiece. This barcode information, also referred to as a POSTNET barcode, is now used by the automated handling equipment, e.g., distribution center sorters, to perform the requisite sorting (i.e., ZIP code or route order). Furthermore, the USPS uses these barcodes or Intelligent Mail Barcodes (IMBs) to encode the destination address.
- While the printed barcode facilitates subsequent handling of a typical mailpiece i.e., one intended for one-way mail communications, the alterations produced by printing a barcode on the face of the envelope can create confusion during a subsequent mail delivery, i.e., mailpieces intended for reuse. For example, destination information printed during the preceding delivery, i.e., the barcode printed by the USPS, can, during a subsequent mail delivery, result in a “returned” mailpiece. That is, if the scanner interprets the previously printed barcode as the current destination address, the mailpiece will be delivered/returned to the sender's address rather than to the actual destination address.
- While the printed barcode can be readily removed by erasure, or obscured by a label, each of these methods requires a positive action by the sender to reuse an envelope. That is, these methods require that directions posted on the reusable envelope, e.g., “remove attached label and cover any information/barcode printed in lower right corner”, be read by the sender and that and that the directions be followed correctly. Inasmuch as such directions can be inadvertently overlooked or incorrectly followed, it is disadvantageous for reusable envelopes to require actions other than those typically associated with mailing envelopes, e.g., open flap, insert content material so that the address can be seen though a transparent window, seal, apply postage, etc. Hence, reusable envelopes which are easy to use, i.e., do not require any unusual actions, will be most successful.
- Other difficulties associated with reusable envelopes relate to the cost of fabrication and, more particularly, to the cost of invested capitol associated with new tooling or automated fabrication equipment. With respect to the latter, envelope manufacturers are, oftentimes, reluctant to invest in new equipment capable of handling the relatively complex flat patterns associated with reusable envelopes. That is, unless the flat patterns closely approximate those required for conventional mailpiece envelopes, a large investment may be required to fabricate unique, one-of-a-kind, tooling for processing more complex patterns. Inasmuch as these incremental additional costs cannot be easily amortized, the cost of the conventional two (2) envelopes can be less and more profitable than the cost of a single reusable envelope.
- A need, therefore, exists for a reusable envelope which is facilitates ease of use and minimizes the cost of fabrication.
- A reusable envelope is provided including a plurality of panels defining a pocket having an opening for receipt of the content material. The reusable envelope also includes a flap closure having first and second bond lines and first and second flap folds disposed between the bond lines. The first flap fold and first bond line are adapted to close the pocket during an initial mail delivery while the second flap fold and second bond line are adapted to close the pocket for reuse during a subsequent mail delivery. A tear strip is disposed between the front panel and the flap closure and opens the pocket for removal of the mailpiece content material following the initial mail delivery. Upon removal of the tear strip and insertion of content material associated with the subsequent mail delivery, the second bond line connects the panels to close the pocket for reuse of the envelope.
- The accompanying drawings illustrate various embodiments of the invention, and assist in explaining the principles of the invention.

While the reusable mailpiece envelope is described in the context of a conventional number ten (10) mailpiece envelope, it will be appreciated that the teachings herein are equally applicable to other style envelopes, e.g., executive style, flats type etc., including other types of reusable envelopes.
-
FIGS. 1 and 2 depict front and rear views, respectively, of a two-dimensional,flat pattern 10F of a reusable envelope 10 (shown folded and assembled in subsequent figures) according to teachings of the present invention. Theflat pattern 10F includes front andback panels Tabs front panel 12 and seal, alongbond lines back panel 14. Thebond lines tabs front panel 12 along tab folds TFL, which facilitate folding of thetabs back panel 14, i.e., once theback panel 14 is folded and in register with thefront panel 12. - A
flap closure 20 is connected to one of thepanels tear strip 26 and includes first andsecond bond lines flap closure 20 defines first and second flap folds FF1, FF2 which are disposed between the first andsecond bond lines second bond line 22B while the second flap fold FF2 is disposed between the first flap fold FF1 and thefirst bond line 20B. The import of such spatial relationships will become apparent when discussing/examining the assembly of thereusable envelope 10 in the subsequent text and drawings. - The
tear strip 26 is disposed between theflap closure 20 and thefront panel 12 and is defined by lines ofperforation perforation lines 30 b, which is contiguous with thefront panel 12, extends across each of the tab folds TFL and includes end portions TP which correspond in shape to the corner edge profile 14EP of therear panel 14. That is, the end portions TP of theperforation 30 b compliment the shape of the edge profile 14EP of therear panel 14 upon being adhesively bonded to each of theside tabs tear strip 26 from the envelope inasmuch as theperforation 30 b cuts through or severs a single thickness of sheet material. That is, the end portions TP of theperforation 30 b avoid difficulties associated with tearing multiple layers of sheet material as may be required when one of thepanels tabs - A crescent or C-shaped perforation PT is disposed along the
tear strip 26 and bifurcates thetear strip 26 intoportions front panel 12, or tab fold line TFL, to facilitate removal of thetear strip 26 and printing of a return address/postage indicia to either side of the perforation PT. - The
front panel 12 includes at least onewindow 40 which bounds a first region RDA for displaying the destination address of theenvelope 10. Additionally, or alternatively, thewindow 40 bounds a second region RPZ corresponding to a zone for printing additionally or supplemental information, i.e., information printed by the delivery agent to facilitate routing of the mailing envelope. In the described embodiment, thewindow 40 includes afilm media 40F bonded to an internal face surface of thefront panel 12 which is sufficiently transparent or translucent to view/read information printed on the internal content material. The second region RPZ of thewindow 40 is formulated to receive inkjet print such that information printed by the delivery agent during an initial mail delivery is unreadable during a subsequent mail delivery. A reusable envelope adapted to prevent the readability of such printed information is described in commonly-owned, co-pending patent application Ser. No. ______ entitled “Reusable Windowed Envelope” (Atty. Docket #. G-521) which is herein incorporated by reference in its entirety. -
FIGS. 3 and 4 depict front and back views, respectively, of thereusable envelope 10 after being folded, assembled and prepared for receipt of content material. Theside tabs rear panel 14 has been folded about the panel fold PFL, and therear panel 14 has been sealed to each of theside tabs bond lines rear panels side tabs FIGS. 3 and 4 show theflap closure 20 in an up/open position to receive content material. - In
FIGS. 5 and 6 , front and rear views of thereusable envelope 10 are depicted after an initial mail delivery. Therein, thetear strip 26 connects theflap closure 20 to thefront panel 12, andpostage indicia 44 is printed between the lines ofperforation tear strip 26. Furthermore, the mail recipient/destination address 46 of theenvelope 10 is viewable through thetransparent window 40, i.e., region RDA of thewindow 40 and aPostnet barcode 48 has been printed by the delivery agent on the region RPZ of the transparent window. As discussed in the Background of the Invention, whenever the delivery agent cannot find, or, for any one of a variety of reasons, fails to read a presort barcode (i.e., a barcode applied by the sender, which is the equivalent of a POSTNET barcode, to receive a presort postage discount), the delivery agent prints thePOSTNET barcode 48 on the face of a mailpiece to facilitate subsequent handling/routing of the mailpiece during mail delivery. It will be also recalled that the region RPZ of thewindow 40 has been coat, treated or otherwise formulated to receive, i.e., be receptive to accept, inkjet print. - In
FIG. 6 , theflap closure 20 folds about the first flap fold FF1 such that a first portion of theflap closure 20 remains coupled to thetear strip 26, i.e., a portion which includes/accepts the second bond line (seeFIG. 4 ) while a second portion of theflap closure 20 may be sealed to therear panel 14 along thefirst bond line 20B. The second flap fold FF2 is disposed between the first flap fold FF1 and thefirst bond line 20B to be used during the subsequent mail delivery, discussed in the following paragraphs. - In
FIG. 7 , the mail recipient opens theenvelope 10 by removal of thetear strip 26. More specifically, a pull strip perforation PT, comprising a central slit CS and aligned punch holes PH to each side thereof, is provided to initiate tearing and removal of thetear strip 26. To avoid damage to theenvelope 10, the pull strip perforation PT may be located between the tab flap folds TFL to bifurcate thetear strip 26 into first andsecond portions perforation tear strip 26 effects removal of the return address and cancelled postage indicia. Moreover, once thetear strip 26 is removed, theflap closure 20 is retained/sealed to an upper edge of therear panel 14. by thefirst bond line 20B. - In
FIG. 8 , theenvelope 10 is opened, i.e., theflap closure 20 is shown in an up/open position, and the content material has been removed, i.e., the content material associated with the initial mail delivery. Further, theflap closure 20 is coupled to therear panel 14 along thefirst bond line 20B. Moreover, in the front view depicted, a portion of theflap closure 20, i.e., the portion containing thesecond bond line 22B, is unfolded (relative to the he first flap fold FF1). Remaining is thePOSTNET barcode 48 which was printed by the delivery agent during the initial mail delivery, i.e., upon recognizing that a Presort barcode was missing. - In
FIG. 9 , the content material for subsequent mail delivery has been inserted such that thedestination address 46 of the mailpiece is viewable through a portion RDA of thetransparent window 40. In the described embodiment, the content material includes a darkened area or strip 52 which corresponds to the region RPZ, i.e., the region of thewindow 40 coated, treated or otherwise formulated to accept or receive inkjet print. As discussed in the co-pending patent application which has been incorporated by reference, the darkened area 52 is operative to diminish or entirely prevent the readability of the previously printedPOSTNET Barcode 48. As such, thebarcode 48 printed during the initial mail delivery will have no impact, or affect on the delivery/routing, during a subsequent mail delivery. - In
FIGS. 9 and 10 , the flap closure 20 (i) folds about the second flap fold FF2, (ii) seals to therear panel 14 along thefirst bond line 20B, and (iii) seals to thefront panel 12 along thesecond bond line 22B. Inasmuch as thetear strip 26 has been removed, the overall height of theenvelope 10 is reduced by about one-half the height dimension HT of thetear strip 26. That is, upon removal of thetear strip 26, theflap closure 20 folds about the second flap fold FF2 and thesecond bond line 22B seals to thefront panel 12. By changing the fold lines, i.e., from the first flap fold FF1 to the second flap fold FF2, the height HE of the envelope is reduced. - In an alternate embodiment of the invention shown in
FIG. 11 , it may be desirable to strengthen or reinforce portions of theenvelope 10 to ensure that thetear strip 26 may be removed without damaging theenvelope 10. For example, a reinforcingfilm 60 may be bonded to the internal face of thetear strip 26, i.e., along its length, to augment the strength of thetear strip 26 inboard of eachperforation film 60 may be the same film media used to produce transparent windows, e.g., thetransparent window 40 for viewing thedestination address 48. - Alternatively, or additionally, in
FIG. 12 , it may be desirable to reinforce theenvelope 10 in areas immediately adjacent to the lines ofperforation perforation film media 40F covering thewindow 40 may be enlarged such that aperipheral edge 40E of thefilm media 40F is bonded immediately adjacent the lower of the two lines ofperforation tear strip 26 and thefront panel 12. While theperipheral edge 40E of thefilm media 40F may extend the full length of thelonger portion 26 a of thetear strip 26, as illustrated,peripheral edge 40E extends from the crescent-shaped pull strip perforation PT to a location midway between the tab folds TFL. With respect to theupper perforation 30 a, thesecond bond line 22B is disposed adjacent and alongside the upper perforation, hence no further structural augmentation or reinforcement is needed. As a result of one or both of the reinforcing techniques described and illustrated inFIGS. 11 and 12 , a tear will follow each line ofperforation front panel 12 orflap closure 20. Consequently, damage to thereusable envelope 10, while opening or re-sealing, can be significantly reduced or entirely eliminated. - In summary, the
reusable envelope 10 of the present invention includes atear strip 26 along the front face of theenvelope 10 to (i) open the envelope, (ii) eliminate printed information associated with the initial mail delivery, e.g., the return address, postage indicia, etc., and (iii) produce a flap closure having bond lines which seal/close the envelop during the initial and subsequent mail deliveries. The periphery of the two-dimensionalflat pattern 10F (shown inFIGS. 1 and 2 ) is essentially identical to the peripheral shape of conventional mailing envelopes, and, accordingly, may be processed/handled by conventional automated fabrication equipment. That is, the shape and size of the reusable envelope is sufficiently similar to that of conventional envelopes such that bond lines, fold lines and perforation lines may be incorporated/produced without significant changes to existing envelope fabrication systems. As a result, the cost of fabricating a singlereusable envelope 10 in accordance with the teachings of the present invention is significantly less than the cost of producing two (2) conventional envelopes, i.e., one for sending a communication and the other for receiving a communication responsive to the first. - It is to be understood that all of the present figures, and the accompanying narrative discussions of preferred embodiments, do not purport to be completely rigorous treatments of the articles and methods under consideration. Consequently, a person skilled in the art will understand that the elements described represent general cause-and-effect relationships that do not exclude intermediate interactions of various types. A person skilled in the art will further understand that the various elements described in this application can be implemented by a variety of different combinations which need not be further elaborated herein.
