An envelope with tear panel

FIELD OF THE INVENTION

The present invention relates to envelopes, and in particular to envelopes adapted to carry indicia. The invention has been primarily developed to allow for an envelope to carry marketing information and will be described herein with particular reference to that application. However, it will be appreciated that the invention is not limited to such a field of use, and is generally applicable to in a broader context.

BACKGROUND TO THE INVENTION Any discussion of the prior art throughout the specification should in no way be considered as an admission that such prior art is widely known or forms part of common general knowledge in the field.

It is known to include marketing information on an envelope, the underlying rationale being to extract additional value from the envelope itself. In some cases the marketing information relates to the business of the sender, whilst in other cases the marketing information relates to the business of a third party that purchases marketing rights from the sender.

Typically, the marketing information is printed on an exterior surface of the envelope. It has been appreciated by the inventor, however, that a consumer, upon receipt of an envelope externally carrying marketing information, may make assumptions regarding the contents of the envelope. In particular, the consumer may assume that the envelope contains solely marketing-related materials - and on that basis discard the envelope and enclosed correspondence as junk mail. This perception makes it less likely for a sender to include external marketing information on an envelope that is to carry relatively important correspondence such as invoices, bank statements, reminders, and so on. In such cases, the possible marketing value of envelopes is not realised.

An alternate approach is to include the marketing information on an interior surface of an envelope. This involves increased envelope production costs due to the associated requirement of double- sided printing. Moreover, there are reasonable chances that the marketing information will not be read by the recipient due to its concealed nature.

SUMMARY OF THE INVENTION

It is an object of the present invention to overcome or ameliorate at least one of the disadvantages of the prior art, or to provide a useful alternative.

In accordance with a first aspect of the invention, there is provided an envelope including: first and second planar envelope portions interengageable to define a cavity for carrying an enclosure; an information panel defined on the first envelope portion, the panel being frangibly separable from the first envelope portion for providing access to the interior of the envelope; and an information display surface on the information panel, the display surface being initially contained within the cavity such that frangible separation of the panel from the first portion provides external access to the display surface.

In some embodiments the first and second portions are envelope halves having a common edge.

Preferably the information panel includes a primary layer integrally formed with the first envelope portion. More preferably the information panel includes a secondary layer mounted to the primary layer for defining the display surface. In a preferred embodiment the secondary layer is adhesibly mounted to the primary layer. The secondary layer preferably has a periphery that substantially conforms to the periphery of the primary layer.

In a preferred embodiment the information panel has a periphery defined by a perforated path on the first portion. Preferably this path is substantially rectangular. More preferably the path defines a tab portion on the information panel for finger engagement to facilitate the frangible separation.

In some preferred embodiments the path is perforated with ties of between about 0.028 inches and 0.036 inches, and preferably about 0.032 inches. In another preferred embodiment the panel is a postage card and more preferably a prepaid or reply paid postage card. Preferably the postage card includes address information disposed on the display surface.

In yet another preferred embodiment the panel is a frangibly removable secondary envelope preferably including at least one region having remoistenable adhesive for selective sealing of said secondary envelope. Preferably the secondary envelope is a prepaid or reply paid secondary envelope. According to a second aspect of the invention, there is provided a system for manufacturing an envelope, the system including: a first processing assembly for providing an envelope sheet including: first and second envelope portions interengageable to define a cavity for carrying an enclosure; a panel defined on the first envelope portion, the panel being frangibly separable from the first portion for providing access to the interior of the envelope; and a second processing facility for providing a label mountable to the panel, the label including an information display surface that is initially contained within the cavity such that frangible separation of the panel from the first portion provides external access to the display surface.

According to a third aspect of the invention, there is provided method for manufacturing an envelope, the method including the steps of: providing an envelope sheet including: first and second envelope portions interengageable to define a cavity for carrying an enclosure; a panel defined on the first envelope portion, the panel being frangibly separable from the first portion for providing access to the interior of the envelope; and providing a label mountable to the panel, the label including an information display surface that is initially contained within the cavity such that frangible separation of the panel from the first portion provides external access to the display surface.

According to a further aspect of the invention, there is provided an envelope including: first and second planar envelope portions interengageable to define a cavity for carrying an enclosure; a panel defined on the first envelope portion, the panel being frangibly separable from the first envelope portion; and

a patch mountable to the first portion for providing an information display surface, the display surface being initially concealed by the panel such that frangible separation of the panel from the first portion reveals the display surface.

In an embodiment the panel is a postage card. Preferably the postage card is prepaid or reply paid. Further, the postage card may include address information disposed such that the address information is initially concealed by the panel and frangible separation of the panel from the first portion reveals the address information.

DETAILED DESCRIPTION Referring to the drawings, it will be appreciated that, in the different figures, corresponding features have been denoted by corresponding reference numerals.

Referring to the drawings, and particularly Figures 1 to 4, an envelope 1 includes first and second planar envelope portions 2 and 3 defined on a paper substrate. These portions are interengageable to progress the envelope from a sheet configuration to a folded configuration. Specifically, the interengagement defines an envelope cavity for carrying an enclosure 4 in the conventional manner. A frangibly separable information

panel 5 is defined on portion 2, and frangible separation of this panel from portion 2 provides one means of access to the envelope cavity. Another means of access is via closure flap 14 in the conventional manner. An information display surface 6 is provided on panel 5, and contained within the envelope cavity when the envelope is in the folded configuration. Frangible separation of panel 5 from portion 2 externally reveals surface 6, as best shown in Figure 2.

In the present embodiment, display surface 6 is used to carry indicia, for example marketing information 7. In overview, information 7 is not visible to a recipient upon initial receipt of envelope 1. However, in using panel 5 to access the envelope cavity, the recipient reveals information 7. As a result, marketing information 7 is less likely to cause preconceptions regarding the contents of envelope 1, particularly when compared with prior art envelopes that externally carry marketing information. Further, marketing information 7 is more likely to be noticed as compared with prior art envelopes that internally carry marketing information. Additionally, the possibility of separating the information panel 5 from portion 2 to reveal the marketing information 7 may advantageously elicit curiosity from at least some recipients of the envelope 1. In this manner the preferred embodiment may contribute to greater market penetration of the marketing information 7. Further, once the information panel 5 has been separated from the portion 2, the resultant additional means of access to the enclosure 4 within the envelope 1 may contribute to higher readership rates for the information enclosed therein. The exterior surfaces 8 and 9 of portions 2 and 3 respectively define a back and a front of envelope 1. Recipient information 10 is provided on surface 9 in line with a conventional addressing method, such as printing, adhesion of a printed label, or provision of a transparent window for displaying information 10 maintained on enclosure 4. For example, in some cases panel 5 is provided on portion 3, and address information is provided on the exterior side of panel 5.

In overview, envelope 1 is folded along fold lines 11 and maintained in the folded configuration by adhesive portions 12. Enclosure 4 is inserted into the envelope cavity, and subsequently a closure flap 14 on portion 3 is folded along fold line 15. An adhesive portion 16 on the interior surface of flap 14 seals this flap to a corresponding location 17 on surface 8 to close envelope 1. Subject to postage tariff requirements, envelope 1 is at that point in a form suitable for delivery.

Although the present embodiments relate to an envelope design where portions 2 and 3 are envelope halves defined on a common paper sheet to include a common edge 18, in other embodiments two-part envelope construction is used. A relatively generic overall single sheet envelope design is disclosed for the purposes of illustration only, and it will be appreciated that this is not to be regarded as limiting in any way.

In the present embodiment, explanatory indicia 20 is provided to facilitate recognition and utilisation of panel 5 by a recipient for the purpose of opening envelope 1. It will be appreciated that a frangibly separable panel 5 presents a simple and convenient solution for opening an envelope, particularly when compared alternative approaches such as the use of a letter- opener.

Panel 5 is frangibly separable due to a perforated periphery 23, which is preferably cut into envelope 1 during the initial envelope manufacture process. In the present embodiment, panel 5 is completely separable from the remainder of portion 2 due to a wholly perforated periphery. In other embodiments one of the edges of panel 5 is unperforated such that panel 5 remains partially connected to the remainder of portion 2 following frangible separation.

In the present embodiment, panel 5 makes use of a laminar construction. More specifically, panel 5 is defined by a printed label 25 adhesibly mounted to the paper envelope substrate. This label 25 defines surface 6 and carries information 7. Label 25 is sized such that it has a periphery 28 that substantially conforms to periphery 23. More precisely, periphery 28 defines a rectangle just inside of periphery 23. In other embodiments panel 5 is defined solely by the material used to form portion 2, and information 7 is printed directly to the interior surface of portion 2 in the region surrounded by periphery 23. However, laminar construction offers numerous non- trivial advantages, as discussed below.

• Increased panel strength. In the present embodiment, panel 5 is intended to be used as a removable and redeemable voucher. As such, there is a need for some structural integrity in panel 5 to reduce the risk of damage to the panel upon its removal from the remainder of the envelope. Laminar construction provides this structural integrity without the need to use a stronger material for the formation of envelope 1 as a whole. It will be appreciated that making use

of a stronger material for the envelope as a whole would add considerably to manufacturing costs.

• Reduced show-through. Show-through refers to an effect where information printed on one side of a paper sheet is visible from the other side. This can reduce the integrity of an envelope. Show-through is dramatically reduced by the use of label 25, primarily as a result of increased panel thickness.

• Increased design flexibility . Envelope manufacturing equipment is typically designed with the objective of increasing throughput and reducing unit costs. As a result, the ability to print information 7 in full colour or with reasonable levels of detail and intricacy is inhibited when using such equipment. By printing information 7 to label 25 outside of the general envelope manufacture process, more flexible printing equipment is available.

• Avoidance of static printing constraints. Envelope manufacturing equipment is generally constrained to static printing methods. This means that every envelope produced includes the same printed information. As a result, if information 7 were printed using envelope manufacture equipment, the same information 7 would appear on each envelope. However, using laminar construction, conventional label printing methods allow for labels 25 to be printed in series. This allows for a large increase in marketing flexibility. Examples include labels including unique identifiers, and labels that provide probability based promotions where a given percentage of panels include "winning" information 7.

An important consideration in the design of envelope 1 is to balance the need for convenient panel removal with the risk of inadvertent panel removal. This is in part achieved by selection of a suitable perforation configuration. Perforation configuration is described in terms of "teeth per inch" (TPI) and tie width. The former relates to the spacing of teeth used in perforation forming machinery, the latter relating to the width of ties that span across the perforation and bridge the gap between perforations formed by the teeth. In the present embodiment, periphery 23 is perforated at 8 TPI with a tie length of about 0.032 inches. That is: about 3.15 teeth per centimetre with a tie width of about 0.081 centimetres. Other embodiments preferably make use of perforations of between 6 and 10

TPI (approximately 2.36 and 3.94 teeth per centimetre) with tie width of between about 0.028 inches and 0.036 inches (approximately 0.071 centimetres and 0.091 centimetres).

While periphery 23 is substantially rectangular, a semicircular tab portion 31 is defined at one side. This tab portion is provided for convenient finger engagement of panel 5 to assist in the removal of that panel 5 by a recipient. Indicia 20, in this case, includes an arrow 32 and "pull here" comment 33 to instruct an recipient in regard to the use of tab 31. A region 34 of periphery 23 defining the periphery of tab 31 is not perforated, and is instead cut such that tab 31 is easily grasped.

In other embodiments alternate tabs or lifting formations are used. As an example, in one embodiment a corner of panel 5 is cut rather than perforated.

Panel 5 should preferably be sized both to allow removal of enclosure 4 from the envelope cavity and also to provide a suitably sized voucher. In the present embodiment the length of panel 5 is approximately 80% the width of portion 3, and in other embodiments sizes of between about 70% and 90% of this width are used. The height of panel 5 is approximately 55% of the height of portion 3, and in other embodiments heights of between about 30% and 75% are used.

Figure 5 illustrates a system 30 for the manufacture of envelope 1. It will be recognised that several distinct manufacturing facilities are used:

• An envelope manufacture facility 41. This facility is responsible for the cutting and printing of spooled paper to form printed envelope substrates. It is specifically noted that perforation of periphery 23 occurs at this point as part of the cutting process;

• A label printing facility 42 for the printing of labels, such as label 25.

• A labelling facility 43 for the mounting of labels to the manufactured envelopes, thereby to define panels 5; and

• A folding facility 44 for progressing envelopes 1 from the sheet configuration to the folded configuration.

In one practical implementation, the entire process occurs in a common plant prior to distribution of envelopes 1. In such a case, a client places an order for a predetermined quantity of envelopes, along with details for marking information that is to appear on those envelopes. Typically, a large number of envelopes are ordered, and these include envelopes having several different labels 25. Whilst facility 41 is better suited for running

large batches of a single type, facility 42 is suitably adapted to vary printing style continuously or intermittently. Unlabeled envelope substrates and printed labels are continuously spooled to facility 43, where labelling is carried out. The labelled envelopes are then passed to folding facility 44, packaged according to the marketing information 7 they carry, and shipped to the client.

In other embodiments, label printing and adhesion is carried out at a client plant following delivery of blank envelope substrates.

There are a number of business models possible on the basis of envelope 1. A few of these are outlined below: • Providing a combined mailing and marketing service to a single customer.

That is, the customer pays for envelopes to be manufactured, labels to be printed and attached on the basis of customer-defined marketing messages, and for enclosures to be placed in folded envelopes. These envelopes are subsequently sealed and delivered. • Providing a low-cost or no-cost mailing service. In this case, a mailing service is provided to a first group of customers at low cost or no cost at all to the first group. On behalf of this first group of customers, correspondence is printed, inserted into envelopes, and delivered to the desired recipients. Marketing space, in the form of panels 5 on these envelopes, is sold to a second group of customers.

• Selling low cost envelopes to a first group of customers, these envelopes including labels 5 carrying marketing material of a second group of customers. This second group purchase marketing rights prior to envelope production.

• Selling appropriately perforated envelopes with blank labels. A customer purchases the envelopes and labels, prints marketing information to the labels using conventional office printing equipment, and subsequently affixes the printed labels to the perforation portions.

Combinations and variations of these general models are also considered. A general notion is that marketing space on panels 5 is of value, and this value perhaps outweighs the envelopes' material and production costs.

It will be appreciated that the above disclosure allows for the manufacture of an envelope particularly well adapted for carrying marketing information. In summary, the

marketing information is internally carried by a frangibly removable panel. This panel is removed to gain access to the interior of the envelope, both encouraging a recipient to open the envelope and to inherently view the marketing material. The general notion is applicable purposes other than marketing. As an example, in some embodiments panel 5 is a pre-addressed postage-paid docket that a recipient posts to confirm receipt of a document.

Figures 6 to 10 illustrate an alternate embodiment of the invention, in the form of envelope 40. Envelope 40 makes use of substantially the same paper substrate as envelope 1. However, information 7 is carried by a patch 50 rather than, or in addition to, label 25. Patch 50 has a first side 51 for carrying information 7, and an opposite second side

52. An adhesive periphery 53 on side 51 allows adhesion of patch 50 to the interior of envelope 40 such that information 7 is concealed by panel 6. Upon receipt of envelope 40, a recipient is urged by indicia 20 to remove panel 6. In this embodiment, removal of panel 6 reveals information 7 printed on side 51 of patch 50, as best shown in Figure 7. Adhesive periphery 53 is defined between an inner rectangular periphery 54, and outer rectangular periphery 55. Inner periphery 54 is slightly larger than periphery 23, and patch 50 is adhered such that periphery 54 surrounds periphery 23. The rationale behind this adhesive configuration is to avoid adhesive connection of patch 50 to panel 6.

An advantage of this embodiment is that upon removal of panel 6 envelope 40 remains generally structurally intact. This may be particularly advantageous for those recipients wishing to retain the contents of the envelope 40 within the envelope 40 subsequent to its opening.

Figures 11 and 12 illustrate another embodiment, in the form of an envelope 60. Numbering conventions from the above example have been adopted for the sake of convenience. In this embodiment, a prepaid or reply paid postage card 61 takes the place of information panel 5. Card 61 is frangibly removable from the remainder of envelope 60 by virtue of a perforated periphery 23, and includes an adhesive label 62 for carrying information including address information and a prepaid or reply paid postage identifier. As was the case in examples above, the use of such a label provides various advantages associated with laminar construction.

From a practical perspective, envelope 60 is particularly useful for facilitating two- way communication between senders and recipients. For instance, a sender uses an

envelope 60 having the sender's return address (or in other embodiments another desired address) printed on label 62. A recipient, upon receipt of envelope 63, optionally frangibly removes postage card 61 and mails it free of charge to the sender as a form of return communication. In some such embodiments envelope 60 includes printed material typically on label 62 for receiving information from a recipient. This printed material is preferably provided on label 62, and in some embodiments includes the likes of forms, checklists, voting means, and so on. In one embodiment a form is provided for a recipient to write personal information including his/her name and address.

It will be appreciated that the address provided on card 61 need not correspond to the sender in all embodiments. For example, in one embodiment the address identifies a third party. In another embodiment there is no address, and the recipient is effectively authorised to send card 61 to a party of his/her choosing.

Examples of possible uses for envelope 60 include surveys and offers for goods and/or services. In one embodiment an envelope 60 is used to facilitate the payment of an invoice. In one such embodiment information printed on label 62 corresponds to information printed on an enclosure of envelope 60. For example, the envelope contains an Invoice X for a Customer Y, and label 62 includes printed information indicative of Invoice X and Customer Y. In one embodiment Customer Y manually adds this information to label 62. Label 62 also includes printed material for allowing Customer Y to provide credit card details or the like for the payment of invoice Y. In overview, the customer receives an envelope containing an invoice, and reviews the invoice. The customer optionally then takes steps to pay the invoice by providing a credit card number or other form of payment authorisation on card 61. The customer then places card 61 in a post box or at another suitable mail collection location. It will be appreciated that information to be communicated by a recipient of envelope 60 using card 61 is on public display during the delivery of card 61. There may be instances where material contained in the return communication is sensitive (such as in the case of credit card information, as mentioned above). In such cases it may be advantageous to use an embodiment such as envelope 70 shown in Figures 13 and 14. In overview, envelope 70 includes a frangibly removable secondary envelope 71.

In the present embodiment secondary envelope 71 includes a prepaid or reply paid postage identifier 72 and carries address information (which in this embodiment is

indicative of the sender of envelope 70 to facilitate two-way communication). This secondary envelope is sealable to define a container for containing and concealing information and/or enclosures in much the same way as a conventional envelope. A recipient optionally frangibly removes secondary envelope 71 in a similar fashion to panel 5 above, provides within the secondary envelope information and/or enclosures, seals the secondary envelope, and subsequently mails it free of charge to the sender of envelope 70.

Secondary envelope 71 includes a portion 75 defined by the perforations on the paper substrate of envelope 70 and bounded by periphery 23, an adhesive label 76 affixed to the interior of portion 75 for providing the abovementioned laminar construction advantages, and a secondary envelope portion 77 of substantially the same size as portion 75. In this embodiment portion 75 and label 76 at least in part define one "half of envelope 71, the other "half being at least in part defined by portion 77.

Portion 77 includes an external face 78 for carrying address information and prepaid or reply paid postage identifier 72. An internal face 79 is oppositely directed with respect to face 78. This face 79 includes a region 80 for carrying an adhesive, typically a one-time use glue. Using such an adhesive, region 80 is, as part of the envelope manufacturing process, adhered adjacent to an edge of label 76 to connect the two envelope halves. Face 79 also includes a peripheral region 81 of remoistenable adhesive. This adhesive is moistened and portion 77 pressed against label 76 to define a cavity within and allow sealing of secondary envelope 71 - a process optionally carried out by a recipient of envelope 70. That is, the adhesive at region 81 is maintained in an unmoistened state during assembly and delivery of envelope 70, and subsequently moistened by a recipient to allow sealing of secondary envelope 71 at an appropriate time. Prior to sealing secondary envelope 71, a recipient typically inserts information into secondary envelope 71. In some embodiments this insertion includes inserting a physical enclosure carrying such information into secondary envelope 71 (such as a payment slip, ballot paper, or the like), whilst in some embodiments the insertion includes writing on to face 79 and/or label 75 ( for example where either or both of these faces include printed information such as surveys, checklists, or forms for completion by the recipient). In either case, information provided by the recipient is able to be contained and concealed within secondary envelope 71 upon sealing of secondary envelope 71, and this information is subsequently able to be returned to the sender free of charge.

Manufacture of envelope 70 is in one embodiment achieved by a process including the steps of:

• Cutting perforations to define portion 75.

• Adhering label 76 to portion 75. • Adhering portion 77 to label 76.

In some embodiments the perforations are cut after adhesion of either or both of label 76 and/or label 77. In other embodiments portion 77 and label 76 are sized such that portion 77 is adhered to portion 75 instead of to label 76, or to a combination of both portion 75 and label 76. In one embodiment label 76 is omitted altogether. An alternate configuration for portion 77 is provided in Figures 17 and 18. In this case the shape and configuration of portions 80 and 81 are modified to provide a secondary envelope having an inherent cavity and opening. Another example is provided in Figures 19 and 20, where portion 77 includes a fold line 83. During the manufacturing process, this portion 77 is folded along line 83 and adhered to portion 75 using adhesive applied at a region 84. It will be appreciated that in this embodiment portion 77 is adhered to portion 75 in much the same way as label 76 to provide a similar laminar construction, and as such label 76 is not required in embodiment such as this. On the opposite face of portion 77 to region 84 is a peripheral region 85 of remoistenable adhesive for allowing sealing of envelope 70. It will be appreciated that various other configurations of portion 77 are used in further embodiments for providing a frangibly removable secondary envelope.

Figures 21 and 22 illustrate another envelope 90, these figures respectively providing front and rear views. As is common in the field, envelope 90 includes on its front face 91 a transparent window 92. Window 92 allows external viewing of a part of an enclosure, this part typically including address information to facilitate delivery of envelope 90. Envelope 90 also includes a secondary transparent window 93 which, at the time of delivery, is concealed by a frangible patch 94 similar to those patches used in examples above. Once patch 94 is removed, it allows viewing of other information contained on the enclosure, which in some cases includes marketing material or information indicative of a prize or other offer.

Figures 23 and 24 illustrate another embodiment, in the form of an envelope 100. Envelope 100 is similar to envelope 1, however upon frangible separation of panel 5,

enclosure 4 remains contained behind a transparent plastic window 101. In some embodiments marketing information is provided on the region of enclosure 4 revealed through window 101. In some such embodiments panel 5 does not carry information of its own, and in some such cases laminar construction of the panel is not necessary. An underlying rationale behind envelope 100 is that a recipient is enticed to remove panel 5, and in doing so reveal information on enclosure 4. The recipient is therefore additionally enticed to remove and more thoroughly review enclosure 4.

Figures 25 and 26 illustrate an embodiment in the form of envelope 110. Envelope 110 combines design features of envelope 1 and envelope 40. Specifically, envelope 110 includes a panel 5 having a laminar construction and optionally carrying information, and additionally a patch 50 that also optionally carries information.

Figures 27 and 28 illustrate an embodiment in the form of envelope 120. Envelope 120 combines design features of envelope 40 and envelope 70. Specifically, envelope 120 includes a secondary envelope 71 having a laminar construction and optionally carrying information, and additionally a patch 50 that also optionally carries information.
