- the closure system 10 may be activated from a first unsealed position 18 by lifting the engageable surface 12 that has the means for engaging the engageable surface 16, away from the passive surface 14 where the means for engaging the engageable surface 16 rests in a first unsealed position 18.
- the means for engaging the engageable surface 16 may then be placed against the engageable surface 12, thereby forming a contact or seal resulting in the second sealed position 20.
- the means for engaging the engageable surface 16 may be further defined as a pressure sensitive adhesive 22.
- the passive surface 12 may be further defined as a release film 24.
- the release film 24 may include compounds such as a silicon release coating. Both the release film 24 and the pressure sensitive adhesive 22 may be applied to an engageable surface 12 in the configurations described above, wherein the engageable surface 12 is paper or plastic.
- the properties of the release film 24 allow for the pressure sensitive
- the pressure sensitive adhesive 22 When positioned in the second sealed position 20, the pressure sensitive adhesive 22 easily adheres to either paper or plastic, when the user gently presses against the engageable surface 12 that has the dry, pressure sensitive adhesive 22.
- the properties of the pressure sensitive adhesive 22 allow the user to use minimal pressure to create a secure seal, and does not require the user to wet or moisten the closure system 10 to initiate the activation of the adhesion, as required in most conventional closure systems.
- the closure system 10 is more hygienic as it is does not require licking by the user, and results in a more environmentally friendly product during its manufacture as its production results in almost zero waste.
- the closure system 10 may be applied to various articles like a conventional paper envelope 26 as described in Figs. 1 , 2, and 3a-c. More specifically, the closure system 10 may be applied by way of example to the following: flat paper envelopes; contoured paper envelopes; 2-way mailers; 3-way mailers; V-fold form system; paper board; corrugated board; cardboard package envelopes; air-mail boxes; signage for retail products: prescription forms; confidential memos and message pads; banking security forms; government forms, such as GST and PST tax forms; confidential inter-office correspondence; direct mail advertising and return order forms; pre-paid postage return mailers; company invoicing; inserts for periodicals and magazines; bulletins; and plastic pouches and the like, some of which are further described below.
- the paper envelope 26 may be adapted to formulate a variety of different mailing systems.
- the closure system 10 may be applied to a two-way mailer 30 comprising of an outgoing mailer 32 and a return mailer 34.
- the closure system In this mailing system, the closure system
- the closure system 10 may be applied to an engageable surface 36, such as paper, of both the outgoing mailer 32 and the return mailer 34.
- the outgoing mailer 32 and the return mailer 34 may be connected to one another by a series of perforations 38.
- a coadhesive 40 may be applied to the outgoing mailer 32 and the return mailer 34 to allow each mailer to be sealed along the sides 42 when the coadhesive 40 adheres to itself.
- the properties of the .coadhesive 40 allow the coadhesive 40 to contact the engageable surface 36 without adhering to it and may be further defined as a water and starch adhesive or a co-hesive adhesive.
- the outgoing mailer 32 is larger in size than the return mailer 34, so that the return mailer 34 can fit within the outgoing mailer 32.
- the return mailer 34 of the two-way mailer 30 may be folded so that the return mailer 34 fits inside the outgoing mailer 32.
- the coadhesive 50 of the return mailer 34 may rest against the engageable surface 44 of the outgoing mailer 32 without adhering to it.
- the closure system 46 of the return mailer 34 is in the first unsealed position 18, so that the means for engaging the engageable surface 56 is resting against the passive surface 58.
- the outgoing mailer 32 may be folded then so that the coadhesive 52 of the outgoing mailer 32 seals the sides 60 of the outgoing mailer 32.
- the closure system 48 of the outgoing mailer 32 may be activated to the second sealed position 20 by placing the means for engaging the engageable surface 62 against the engageable surface 44.
- the return mailer 34 may be detached from the outgoing mailer 32 along the perforations 38.
- the return mailer 34 may be used to enclose information that could be returned to the sender of the outgoing mailer 32.
- the closure system 46 of the return mailer 34 may be activated in manner described above for the outgoing mailer 32.
- the configuration of the outgoing mailer 32 and the return mailer 34 with the closure systems, 48 and 46 respectively, allows for the easy insertion of the two-way mailer 30 into printers for printing information on the engageable surface 44 of the outgoing mailer 32, and the engageable surface 54 of the return mailer 34. Storage of the two-way mailer 30 is also trouble-free, as the means for engaging the engageable surface, 56 and 62, and the coadhesive 50 and 52 are in the first unsealed position 18 and can not adhere to any other surfaces.
- the closure system 10 may also be used in conjunction with a return mailer 62.
- a return mailer 62 may consist of a statement portion 64 and a return envelope 66 connected to one another by a series of perforations 68.
- the statement portion 64 may contain printed information that the sender wishes to communicate to the recipient.
- the return envelope 66 may then be used by the recipient to enclose any information that could be conveyed to the sender.
- the return mailer 66 may include a closure system 70 identical to the closure system 10 described above.
- the return mailer 62 may be enclosed in an envelope with a closure system 10 as described in Figs. 1 , 2 and 3a-c and sent to the recipient.
- the recipient of the return mailer 62 may separate the statement portion 64 from the return envelope 66 along the series of perforations 68. The recipient may then return any information or payment to the sender by using the return envelope 66. More specifically, the user would lift the means for engaging the engageable surface 72 away from the passive means 73 and allow the means for engaging the engageable surface 72 to contact the engageable surface 74 and seal the return envelope 66. As described in Figs. 4, 5, and 6a-c, a coadhesive 76 would seal the sides 78 of the return envelope 66. The recipient would therefore keep the statement portion 64 of the return mailer 62 for their records. The orientation of the return mailer 62 allows the user to easily print information on the statement portion 64 and the return envelope 66 without engaging the closure system 70.
- the closure system 10 may be applied to a V-fold form 80.
- the V-fold form 80 may comprise of first panel 82 and a second panel 84.
- the panels 82 and 84 are connected by a series of perforations 86.
- Both panels 82 and 84 have closure systems, 88 and 90 respectively.
- the orientation of the closure systems 88 and 90 allows for the following associations.
- the passive surface 92 of the first panel 82 may associate with the means for engaging the engageable surface 94 of the second panel 84; and the passive means 96 of second panel 84 may associate with the means for engaging the engageable surface 98 of first panel 82.
- the closure systems 88 and 90 may be preferably located at the centre of the V-fold form 80, although the closure systems 88 and 90 may be located in a variety of positions (by way of example, horizontal or vertical) to accommodate the many applications of the V-fold form 80.
- the V-fold form 80 may be used where the first panel 82 is detached from the second panel 84 along the series of perforations 86 exposing the second panel 84.
- both the first panel 82 and the second panel 84 include closure systems 88 and 90 respectively
- the user may fold the engageable surfaces 100 and 102 of either panel and engage the means for engaging the engageable surfaces 94 and 98.
- the closure systems 88 and 90 By engaging the closure systems 88 and 90 to a second sealed position 20, the user may render any information on the panels 82 and 84 confidential and more difficult to tamper with.
- the V-fold form 80 may be used in multiples.
- the V-fold form 80 may be in a pad format as described in Fig. 11 , such as prescription pads or confidential note pads.
- the orientation of the V-fold form 80 allows for the easy insertion into a printer to allow for the printing of information on the engageable surfaces 100 and 102 without exposing the means for engaging the engageable surfaces 94 and 98 to the printing process. This is significant as most conventional closure systems are printed with the adhesive exposed.
- the V-fold form 80 is manufactured in a flat format, which allows the user to save on storage space as the V-fold form 80 can contain both a letter portion and an envelope portion.
- closure systems 80 and 90 described above may be applied to most paper products, and most plastic products such as plastic pouches. In all instances, the closure systems 80 and 90 allow for information to be printed on the engageable surfaces 100 and 102 using high speed commercial printing equipment resulting in more efficient manufacturing. Printing of the V-fold form 80 can also occur on ink jet or laser printers, any home printing equipment or even labelled by hand.
- the closure systems 80 and 90 also allow for easy photocopying as the means for engaging the engageable surfaces 100 and 102 do not adhere to any surface such as the heat pad or roller of a photocopying machine.
- the closure system 10 also results in a more environmentally friendly product as there is no additional waste from tear strips and perforated edges.
- a pressure-sensitive adhesive 22 the closure system 10 does not require any additional wetting or moisture and is more hygienic since it does not require licking.
- the mailing systems described above may also be stored in a variety of formats. Referring to Figs. 12a-d, by way of example, the envelope 26 may be manufactured in a continual tear-away format that allows the envelopes 26 to be stored in either a roll or a fan-fold formats. These formats allow for the user to use the envelope 26 in continuous printing.
