Abstract
A closure system comprised of a passive surface, an engageable surface and an adhesive surface that may be applied to a number or surfaces such as paper and plastic.
Description
- This invention relates generally to a closure system and more specifically to a closure system for paper or plastic products.
- Since the advent of letter writing, closure systems for paper products such as envelopes have progressed from sealing wax to more innovative closure systems that use a variety of adhesives and sealing mechanisms. Many of these closure systems often require wetting the adhesive or removing an additional element such as a pull tear or release paper.
- The purpose for developing some of these closure systems was to improve convenience for the user when sending paper products such as envelopes, as well as trying to increase the confidentiality associated with sending letters. Prior art closure systems have been devised to address some of the aforenoted problems with closure systems.
- For example, U.S. Pat. No. 5,474,229 issued to Shimazaki on Dec. 12, 1995 describes a method and apparatus for stacking pressure-sensitive adhesive envelopes. The invention relates to a stack of envelopes wherein each envelope can be easily removed from the stack and used without having to moisten the flap. Specifically the flaps of the envelopes are treated on the backside with a release coating and on the front side with a pressure sensitive adhesive. The envelopes are stacked with the flaps open so that there is an impermanent, adhering interface between the release coating and the pressure sensitive adhesive.
- U.S. Pat. No. 5,642,855 issued to Michlin on Jul. 1, 1997 discloses a composite outgoing mailer and return envelope form. The invention describes a one piece Z-folding form for a outgoing mailer. With the removal of tear strips from two sides of the outgoing mailer and removable panels, the remainder may be folded into a return envelope.
- U.S. Pat. No. 5,400,594 issued to Kaye on Mar. 28, 1995 discloses a reversible-returnable envelope blank. Specifically the reversible and returnable envelope blank is generally cross-shaped and uses a non-permanent reusable, resealable low tack pressure sensitive adhesive so that the envelope can be folded inside out and used as a return envelope.
- U.S. Pat. No. 5,375,764 issued to Sauerwine on Dec. 27, 1994 describes a double parallel heat seal mailer. The invention discloses a double parallel mailer which may include a return envelope with a side edge opening or a booklet. More specifically the mailer includes a first outgoing portion and a return portion which can be detached from the first outgoing portion.
- U.S. Pat. No. 5,052,613 issued to Lin on Oct. 1, 1991, describes a two-way envelope. More specifically the invention discloses an envelope that may be used for both an original and return mailers and includes removable and reusable address labels. The invention further describes a number of different ways to fold the mailer so that there is an outgoing portion and a second return portion.
- A closure system for both paper and plastic products that does not require any moistening of the adhesive, allows for easy application to envelopes or mailing systems, and allows for easy storage, printing and use of the paper and plastic products is desirable.
- An object of one aspect of the present invention is to provide an improved closure system.

Theoutgoing mailer 32 and thereturn mailer 34 may be connected to one another by a series ofperforations 38. Acoadhesive 40 may be applied to theoutgoing mailer 32 and thereturn mailer 34 to allow each mailer to be sealed along thesides 42 when thecoadhesive 40 adheres to itself. The properties of thecoadhesive 40 allow thecoadhesive 40 to contact theengageable surface 36 without adhering to it and may be further defined as a water and starch adhesive or a co-hesive adhesive. Typically theoutgoing mailer 32 is larger in size than thereturn mailer 34, so that thereturn mailer 34 can fit within theoutgoing mailer 32. - Referring to FIGS. 4, 5, and6 a-c, in operation, the
return mailer 34 of the two-way mailer 30 may be folded so that thereturn mailer 34 fits inside theoutgoing mailer 32. Thecoadhesive 50 of thereturn mailer 34 may rest against theengageable surface 44 of theoutgoing mailer 32 without adhering to it. Theclosure system 46 of thereturn mailer 34 is in the first unsealedposition 18, so that the means for engaging theengageable surface 56 is resting against thepassive surface 58. Theoutgoing mailer 32 may be folded then so that thecoadhesive 52 of theoutgoing mailer 32 seals thesides 60 of theoutgoing mailer 32. Theclosure system 48 of theoutgoing mailer 32 may be activated to the second sealedposition 20 by placing the means for engaging theengageable surface 62 against theengageable surface 44. - Upon receipt of the
outgoing mailer 32, thereturn mailer 34 may be detached from theoutgoing mailer 32 along theperforations 38. Thereturn mailer 34 may be used to enclose information that could be returned to the sender of theoutgoing mailer 32. Theclosure system 46 of thereturn mailer 34 may be activated in manner described above for theoutgoing mailer 32. The configuration of theoutgoing mailer 32 and thereturn 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 theengageable surface 44 of theoutgoing mailer 32, and theengageable surface 54 of thereturn 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 unsealedposition 18 and can not adhere to any other surfaces. - Referring to FIGS. 7 and 8, the
closure system 10 may also be used in conjunction with areturn mailer 62. Areturn mailer 62 may consist of astatement portion 64 and areturn envelope 66 connected to one another by a series ofperforations 68.
