The present disclosure relates generally to mailer forms and, more particularly, to confidential postcards.
Mailers come in a variety of different configurations and are commonly used for a variety of applications as an effective way to distribute information. Mailers in the form of postcards provide savings in postage charges. However, on Feb. 5, 2004, the United States Postal Service (USPS) revised Domestic Mail Manual (DMM) C100.2.9 to state that only the top or bottom of a double postcard, once folded, may be sealed and that the sealing of the sides of double postcards, regardless of method, is not permitted. Consequently, confidential information contained in a double postcard mailer would be plainly viewable.
Postcards such as, for example, outgoing mailings and return postcards advantageously provide substantial savings in postage charges over conventional letters. For example, the current cost to mail a postcard via the USPS is less than mailing a regular letter. Such cost savings provide an incentive to utilize postcards for a wide variety of standard and/or specialized mailings.
However, postcards must meet certain USPS regulations. One such regulation requires postcard mailing pieces to meet particular weight (pounds per surface area) or thickness requirements. Further regulations require postcards to have a certain thickness, weight, and/or size so that the postcards can travel through postal sorters or other postal equipment without difficulties. For example, current USPS postcard regulations state that a postcard must have a height between 3.5 inches and 4.25 inches, a length between 5.0 inches and 6.0 inches, a thickness between 0.007 inches and 0.016 inches, and a weight of no more than 1 ounce. Thus, it is desirable for an outgoing mailer to qualify as a postcard to realize the postal mail savings for a first class postcard versus a first class letter. However, such requirements often limit the use of postcards. For example, the thickness requirement may limit the types of printers with which such postcards can be utilized, making the use of postcards more difficult and undesirable.
In addition, current USPS regulations state that the left and right sides of double postcards cannot be sealed. Consequently, all information contained on the interior panels of a double postcard would be plainly visible to any one who squeezed the folded double postcard to separate the interior panels to peek inside. If confidential information were contained on the postcard, this information would then be known to anyone who looked inside the postcard.
An example mailer form described herein has a return postcard integrally formed with the mailer such that when fully assembled, the return postcard satisfies the USPS regulations and requirements such as, for example, weight, thickness and size requirements. To meet USPS postcard thickness requirements without limiting the type of printer that can be used, the mailer form (e.g., a double V-fold mailer form) and, thus, the return postcard, are formed from a single sheet of paper or stock. The single sheet enables various or custom indicia such as, for example, personalized customer information, to be printed on a first or single side of the form via for example, a laser printer, a personal printer, an industrial printer, and/or any other suitable printer. In addition, the example postcard forms described herein contain confidential areas that are not plainly viewable by anyone without separating, substantially or completely, or fully opening the panels of the example postcard forms.
One of the example postcard or mailer forms described herein includes two panels, one of which serves as a return postcard (e.g., a business return postcard, a courtesy return postcard, etc.). In this example, at least one of a first face of a first panel and a first face of a second panel includes a first adhesive portion that receives adhesive to adhere the first panel and the second panel to form a postcard when the form is folded as an outgoing mailer. The first panel includes indicia related to the reply postcard, and the second panel may include, for example, instructions, advertisement information or any other information. A portion of at least one of the first panel or the second panel includes a second adhesive portion, apart or separate from the first adhesive portion. The second adhesive portion defines a confidential pocket or area in which confidential information may be included. The second adhesive portion couples the first and second panels so that the information contained in the confidential pocket is not viewable when the form is folded as an outgoing mailer.
The example configuration advantageously enables a user to print personalized data or information to a particular recipient onto the postcard and/or the confidential pocket or area either by printing on only one side of the form (e.g., where the form is a double V-fold type form) or on both sides of the form (e.g., where the form is a V-fold type form) when the form is fed through, for example, a laser printer. Such personalized or otherwise confidential information may include, for example, a recipient's name, account number, and/or other information on the form as detailed herein.
The information in the example mailer form may be human and/or machine readable information, which may be pre-printed on the example form, printed on the form when the form is passed through a printer such as, for example, a laser printer, handwritten on the form, provided via a label, and/or any combination thereof.
Another example mailer form described herein includes four panels having an integral return postcard (e.g., a business return postcard, a courtesy return postcard, etc.) formed from two adjacent panels when the form is folded as an outgoing mailer. For instance, in one example, the mailer forms include a first face of a first panel and a first face of a fourth panel that represent respective first and second sides of the return postcard when the form is folded and the first and fourth panels are adhered together. A second side or face of the first and fourth panels include first adhesive portions that receive adhesive to adhere the first panel to the fourth panel to form a reply postcard when the form is folded along a first fold line. At least one of a first face of a first panel and/or a first face of a second panel includes second adhesive patterns or portions that receive adhesive to adhere the first and second panels together as an outgoing mailer. The first and fourth panels include reply card indicia, the third panel includes addressee indicia, and the second panel may include, for example, instructions, advertisement information or any other information, though the order and contents of the panels may be changed. When the form is folded as an outgoing mailer, the second panel is disposed between the first panel and the third panel.
A portion of at least one of the first panel or the second panel includes a third adhesive portion, apart or separate from the first and second adhesive portions. The third adhesive portion defines a confidential pocket or area in which confidential information may be included. The third adhesive portion couples the first and second panels so that the information contained in the confidential pocket or area is not viewable when the form is folded as an outgoing mailer. As the illustrated examples show, this third adhesive pattern on the first face of the first and/or second panels may be omitted and the confidential box may be defined by the second adhesive pattern.
A form configuration with a confidential box or area advantageously enables a user to provide personalized data or other confidential information to a particular recipient via the postcard and/or the confidential pocket or area as noted above, thereby maintaining the secrecy of such information.
The example postcard construction 102 includes a first panel 200 and a second panel 202. The first panel 200 and the second panel 202 are separated by a fold line 204 or other line of weakness. To form the outgoing mailer (i.e., the outgoing postcard), the first panel 200 and second panel 202 are folded in a V-fold about the fold line 204 so that a first face 206 of the first panel 200 is opposite and coupled to a first face 208 of the second panel 200. At least one of the first face 206 of the first panel 200 and/or the first face 208 of the second panel 202 includes a first adhesive pattern 210 to releasably couple the first panel 200 and the second panel 202. In this example, the first adhesive pattern 210 is shown as a series of distinct adhesive spots. However, any other suitable pattern may be used as well including solid strips or lines, series of dots, etc.
In this example, the first panel 200 forms a reply postcard that may be detached from the second panel 202 and used by the recipient of the postcard construction 102 to respond to an offer, for example. The first face 206 of the first panel 200 includes the face of the reply card and, thus, may include addressee indicia 212, a stamp area 214, a barcode area 216 for post office barcoding, and an area for face identification marks (FIM) 218, etc. A second face 300 (
The second panel 202 forms the portion of the outgoing mailer that provides the recipient with the intended information in a message area 220 on the first face 208 of the second panel 202. A second face (not shown) of the second panel 202 forms the front face of the outgoing mailer and, therefore, include address indicia for the recipient/addressee. An example front face of an outgoing postcard mailer is shown in
At least one of the first face 206 of the first panel 200 and/or the first face 208 of the second panel 202 includes a second adhesive pattern 222, which is set apart or is separate from the first adhesive pattern 210. In this example, the second adhesive pattern 222 is shown as a series of distinct adhesive spots. However, any other suitable pattern may be used as well including solid strips or lines, series of dots, etc. On the first panel 200, the first adhesive pattern 210 and the second adhesive pattern 222 define the barcode area 216, without interfering, in terms of either printing or readability, with any barcode contained therein. In some examples, the barcode area 216 is a 0.625 inch wide rectangle that starts at a bottom edge 224 of the first panel or reply card 200 and continues up to 0.625 inches from the bottom edge 224. However, in other examples, other shapes and dimensions may be used instead or in addition to those recited here.
On the second panel 202, the first adhesive pattern 210 and the second adhesive pattern 222 define a confidential pocket, box or area 226. In the confidential area 226, personal and/or confidential information may be printed. When the postcard construction 102 is formed as an outgoing mailer, the sides of the mailer are left unadhered, as required by the USPS, and a postal inspector, employee or other person can look into the outgoing mailer and read the information shown on the first face 206 of the first panel 200 and the first face 208 of the second panel 202, outside of the confidential area 226 because the first adhesive pattern 210 and the second adhesive pattern 222 ensure the confidential area 226 remains covered.
Though the first adhesive pattern 210 and the second adhesive pattern 222 are described as separate adhesive patterns, these adhesive patterns maybe be contiguous, coincide, flow together or otherwise combined into one adhesive pattern that provides an area that remains sealed from view when the form is folded as an outgoing mailer.
The form 100 may also include a perforation or other line of weakness 228 through most or all of the second panel 202. The perforation 228 separates the confidential area 226 from the remainder of the second panel 202. The perforation 228 may be manipulated by the recipient, for example, to remove the confidential area 226 and, thus, the sensitive information contained therein, from the remainder of the postcard construction 102.
The example form 400 includes top and bottom edges 402 and 404, respectively, and parallel first and second side edges 406 and 408, respectively. In this example, the top and bottom edges 402 and 404 are substantially perpendicular to the side edges 406 and 408. The form 400 further defines a front face or first side 410 (
The example form 400 includes first, second and third lines of weakness or fold lines 412, 414 and 416. The example fold lines 412, 414 and 416 are substantially parallel to the top and bottom edges 402 and 404 and extend substantially transverse to, and at least partially between the side edges 406 and 408 to divide the form 400 into four panels 418, 420, 422 and 424. The first panel 418 is the top panel of the example form 400, the second panel 420 is the second panel of the example form 400, the third panel 422 is the third panel of the example form 400 so that the second panel 420 is between the first panel 418 and the third panel 422, and the fourth panel 424 is the bottom panel of the example form 400 so that the third panel 420 is between the second panel 420 and the fourth panel 424.
The example lines of weakness or fold lines 412, 414 and 416 may be any suitable type including, for instance, perforation lines, die cut lines, scores or creases, etc., to facilitate folding of the example form 400 and/or removal of the panels 418, 420, 422 and/or 424 by an end user or recipient of the form 400.
In this example, the first, second and third fold lines 412, 414 and 416 extend substantially the entire distance between the first and second side edges 406 and 408 and each of the fold lines 412, 414 and 416 is substantially continuously formed. In other examples, at least one of the first, the second, or the third fold lines 412, 414 and 416 may extend less than the entire distance between the first and second side edges 406 and 408 and/or may be formed by two or more collinear fold lines. For example, the fold lines 412, 414 and 416 may be discontinuously formed. Thus, the first, second, third, and fourth panels 418, 420, 422 and 424 in combination define the form 400 prior to folding as an outgoing mailer as described below. The first panel 418 is interconnected with the second panel 420 via the first fold line 412, the second panel 420 is interconnected with the third panel 422 via the second fold line 414, and the third panel 422 is interconnected with the fourth panel 420 via the third fold line 416. The first, second, third and fourth panels 418, 420, 422 and 424 are interconnected in a manner that enables the first, second, third, and fourth panels 418, 420, 422 and 424 to be double parallel folded onto each other as explained in greater detail below.
The first, second, third, and/or fourth panels 418, 420, 422 and 424 may include human and/or machine readable indicia that may be pre-printed on the example form 400, printed when the form 400 is passed through a printer such as, for example, a laser printer, handwritten on the form 400, provided via a label, and/or any combination thereof. Additionally or alternatively, the first, second, third, and/or fourth panels 418, 420, 422 and 424 may include personalized information relating to a particular recipient/customer of the example form 400 and/or any other suitable information. In some examples, each of the first, second, third and/or fourth panels 418, 420, 422 and 424 may be left blank. Furthermore, in this example, the second panel 420 may include confidential information and, as explained in detail below, a portion of the second panel 420 is sealed when folded as the example outgoing mailer, thereby assuring confidentially and show-through protection for information on the second panel 420.
In this example, the first side 410 of the first panel 418 includes a barcode area 426 that may include a barcode or in which the USPS may print a barcode or other routing and/or processing information. The first side 410 of the first panel 418 also includes a first pattern of adhesive 428, which, in the illustrated example, outlines or surrounds the barcode area 426. In other examples, the first adhesive pattern 428 may be disposed on a different area of the first panel 418 or on a different one of the panels 418, 420, 422 and/or 424. Furthermore, though the first adhesive pattern 428 is shown as a series of spots, any type of pattern including, for example, solid strips, dots, etc. may be used instead of or in addition to the series of spots. The first side 410 of the first panel 418 also includes a first addressing area 430 that may be used, for example, for addressing information for the addressee of a reply card.
The first face 410 of the second panel 420 includes a second adhesive pattern 432 in addition to or as an alternative to the first adhesive pattern 428. In other examples, the second adhesive pattern 432 may be disposed on a different area of the second panel 420 or on a different panel. Furthermore, though the second adhesive pattern 432 is shown as a series of spots, any type of pattern including, for example, solid strips, dots, etc. may be used instead of or in addition to the series of spots. The second adhesive pattern 432 defines a confidential pocket, box or area 434, which may be used to contain personalized, confidential or otherwise sensitive information. As described in further detail below, when the form 400 is folded as an outgoing mailer, the first adhesive pattern 428 and/or the second adhesive pattern 432 couple the first face 410 of the first panel 418 and the first face 410 of the second panel 420 such that the confidential area 434 is not exposed and is not exposable by postal employees or anyone else without compromising the bond between the first sides 410 of the panels 418 and 420 created by the first adhesive pattern 428 and/or the second adhesive pattern. 432. In some examples, the second panel 420 also may include a first perforation 435 or other line of weakness. The first perforation 435 may be manipulated by the recipient of the form 400 to remove the confidential area 434 from the form 400.
In this example, the first side 410 of the third panel 422 includes an area 436 for address information of the addressee of the outgoing mailer. The first face 410 of the third panel 422 may also include a stamp area and other areas containing postal information (e.g., return addresses, FIMs, etc.) as desired. In addition, the third panel 422 may include a second perforation or other line of weakness 437. The second perforation 437 aligns with the first perforation 435 when the form 400 is folded about the second fold line 414 as described below. When the second panel 420 and the third panel 422 are coupled as detailed below, the second perforation 437 facilitates manipulation of the first perforation 435 to remove the confidential area 434.
The first face 410 of the fourth panel 424 forms the back of the reply card and may contain any desired and/or appropriate information. In some examples, the fourth panel is left blank.
To fold the form 400 into an outgoing mailer, the form 400 is first folded, as shown in
A fourth adhesive pattern 504 may also be included on the second face 500 of the third panel 422 to couple the second face 500 of the third panel 422 to the second face 500 of the second panel 420. Though not shown, there may be additionally or alternatively a fifth adhesive pattern and/or a sixth adhesive pattern disposed similar to either of the first, second, third or fourth adhesives patterns 428, 432, 502 and 504 on the second faces 500 of the first panel 418 and/or the second panel 420 for coupling these panels to the fourth panel 424 and third panel 422, respectively.
As shown in
As shown in
To open the form 400, the recipient applies sufficient force to separate the first panel 418 and fourth panel 424 from the second panel 418 and third panel 422 by overcoming the adhesive bond created by the first adhesive pattern 428 and/or the second adhesive pattern 432. The first panel 418 and fourth panel 424, which form the reply card, may be removed by separating these panels from the second panel 420 and the third panel 422 along the first fold line 412 and third fold line 416. In addition, as noted above, the confidential area 434 may be removed by separating the confidential box 434 from the remainder of the second panel 420 along the first perforation 435 and, in some examples, along the second perforation 437 as well.
In some examples, the form 400 may include a security marker 700, which indicates whether the adhesive bond formed by the first adhesive pattern 428 and/or the second adhesive pattern 432 between the first face 410 of the first panel 418 and the first face 410 of the second panel 420 has been broken, tampered with, disengaged, re-engaged or otherwise compromised. In this example, the security marker 700 is a tab (e.g., a label or sticker), that extends over the edge of the form 400 where the top edge 402, the bottom edge 404 and the second fold line 414 meet. If the first panel 418 and second panel 420 are separated so that the confidential area 434 is exposed, the security marker 700 will rip and, thus, provide evidence of the exposure of the confidential area 434. In other examples, the security marker 700 may be a staple or other suitable mechanical or chemical fastener. In addition, there may be a plurality of security markers including, for example, two tabs located over the edge of the outgoing mailer toward each of the left and right sides.
As noted above, the various panels may include any desired and or appropriate human and/or machine readable information or may be left blank. Such information may include, for example, instructional information, receipt information, an advertisement, a coupon, a gift receipt, a gift card, promotional information, a negotiable instrument, a rebate, payor and payee information, headings, titles and/or logos. Additionally or alternatively, the panels may include personalized information tailored specifically for each recipient that is to receive the example mailer 400. Such information may include, for example, a customer name, an item name and model number of a purchased item, a date of purchase, a method of payment, a rebate amount, a date a rebate was paid, and/or any other suitable personalized information.
The reply card (e.g., the first panel 418 and the fourth panel 424) may be a business reply postcard, a courtesy reply postcard and/or any other suitable postcard. The reply card may include a survey, a request for promotional discounts or rebates, a purchase request, extended warranty information, a request for additional information relating to the extended warranty, a request for information or rebate information for various products, truncated credit card information, an authorization signature line to purchase a product or service such as, for example, extended warranty coverage for a purchased item, the recipient's name, address information, other personal information, and/or a section to correct such information if it is incorrect. The reply card may also include return address indicia, address barcode information, postage indicia and/or any other suitable indicia or information.
The confidential area 434 may contain the more sensitive and personal information including, for example, any financial information, a credit card number, a portion of a credit card or account number, a password, an address, a check number, an amount of money, a ticket number, a phone number, a name, a social security number, a portion of a social security number, a code, a test result, an acceptance decision (e.g., to a college), a prescription, a judgment or any other confidential and/or personal information.
The indicia or information on the first, second, third or fourth panels 418, 420, 422 and 424 can be inverted from the orientation shown or printed in any other manner. In this example, the first, second, third and fourth panels 418, 420, 422 and 424 are substantially the same size (e.g., the same width and length). In other examples, the panels 420, 422 and 424 may be any suitable size. In still other examples, the panels 420, 422 and 424 may be configured in any suitable arrangement so that the form 400 may be folded as a Z-fold configuration, a C-fold configuration, and/or any other suitable fold configurations.
The adhesive patterns 210, 222, 428, 432, 502 and 504 described herein are pressure activated adhesives. By utilizing a pressure activated adhesive, the example forms 100 and 400 may be processed through a printer without having the adhesive impair or damage the printer because the rollers of a printer do not apply sufficient pressure to the forms 100 and 400 to activate the adhesive. When folded via, for example, a folding machine, the folded forms 100 and 400 are passed through a roller or other pressure applying devices that apply sufficient pressure to active the adhesive on the adhesive patterns 210, 222, 428, 432, 502 and/or 504 to secure or hold the folded forms 100 and 400 as the example outgoing mailers shown herein. However, in other examples, the adhesive patterns 210, 222, 428, 432, 502 and 504 may include a variety of different adhesives such as, for example, rewettable adhesive, heat activated adhesive, and/or any other suitable adhesive or chemical fastening substance(s).
In addition, in some or more of the illustrated examples, one or more of the adhesive patterns 210, 222, 428, 432, 502 and 504 may be permanent adhesives such as a pressure seal adhesive, cohesive, and/or any other suitable fastening substance. For example, the fourth adhesive pattern 502 forms the reply card upon folding the form 400 and the application of suitable pressure to the fourth adhesive pattern 502. Furthermore, in some examples, the fourth adhesive pattern 502 may be substantially continuous to preclude delamination of the return postcard. The other adhesive patterns 210, 222, 428, 432 and 504 may be continuous as well. However, in other examples, the adhesive patterns 210, 222, 428, 432, 502 and 504 may be provided as a plurality of discontinuous elements (strips, spots, etc.) and/or may be disposed in any suitable pattern, shape, or density.
Any feature of any example described herein may be combined with any other feature of any example described herein. In addition, though V-fold and double V-fold postcards are described herein, the one or more of the features of these examples may be included in any type of postcard, mailer or business form. In addition, the example forms described herein are not limited to the described series and orientations of panels, and may be reversed or changed in any suitable manner.
Although certain example apparatus and articles of manufacture have been described herein, the scope of coverage of this patent is not limited thereto. On the contrary, this patent covers all apparatus and articles of manufacture fairly falling within the scope of the appended claims either literally or under the doctrine of equivalents.
This patent claims the benefit of the filing date of U.S. Provisional Application Ser. No. 61/154,799, filed Feb. 24, 2009, entitled “Confidential Postcards,” and incorporated herein by reference in its entirety.
