Definitions

  • the present invention in some embodiments thereof, relates to envelopes and, more particularly, but not exclusively, to tamper-resistant and tamper-evident envelopes.
  • Envelopes are commonly used for packaging written/printed material and relatively small items which are to be sent by a sender in a first location to a receiver in a second location. These may include money, notes, classified documents, valuables, among others.
  • the envelope is entrusted to a third party, which may be a complete stranger, who assumes responsibility for transporting the envelope from the sender to the receiver.
  • transport of the envelope may be done by a postal service.
  • a private delivery service such as a courier may be used.
  • a main concern of the sender, and frequently also the receiver is that the envelope be received at the second location without having been tampered with. If tampered with, this may be an indication that the contents inside the envelope has been meddled with, and its confidentiality violated.
  • Tamper-resistant and tamper-evident envelopes are known in the art, generally designed so as to allow the third party transporting the envelope (hereinafter may be referred to as “courier” or “deliverer) and/or the receiver to visibly corroborate tampering with the envelope.
  • US Patent No. 5,727,686 "TAMPER-EVIDENT SECURITY ENVELOPE"
  • a tamper-evident envelope has a first layer of paper-containing material and a second layer of paper-containing material attached to each other along a number of seams.
  • Each seam includes a pattern embossed and/or perforated through both layers along a major part of the seam. If the envelope is opened and resealed along one of these seams, the embossed or perforated pattern is corrupted, thereby making the unauthorized opening of the envelope readily apparent to an intended recipient.”
  • US Patent No. 5,918,983 "SECURITY ENVELOPE"
  • a security envelope for transporting valuable documents and articles includes a thin header formed of thin frangible material secured to the back panel having an adhesive layer that seals the header to the front panel upon folding and pressing closed.
  • An inner layer of adhesive on the inner surface of the back panel seals the inner front and back panel surfaces to close the envelope chamber and extends further toward the envelope bottom than the header adhesive layer when sealed to prevent tampering tool access to the envelope chamber.
  • Application of tampering heat will shrivel the header and cold sufficient to release the inner adhesive layer will cause pieces of the outer adhesive layer to break off and fall away.
  • Printed indicia on the header inner surface and a transparent flood coat on the inner header surface will adhere to the header adhesive layer and aid in the tampering attempt indication.”
  • US Publication No. 2008/0156855 "SECURE ENVELOPE AND METHOD FOR SECURING INFORMATION"

  • the flap has an interior and an exterior side and is attached to the second panel at an edge of the second panel opposite the closed edge portion.
  • the envelope comprises thereon an adhesive layer on the interior side of the flap comprising an adhesive; wherein a non-transparent window is located on the first panel or the second panel.

Furthermore, it should be evident to one skilled in the art that the method described may be varied to include more steps, less steps, a different order of steps, and is not intended to be limiting in any way.
  • sheets from which the front panel and the rear panel are prepared are laminated with an optically opaque laminated film; for example laminated film 220 in FIGURES 2A and 2B .
  • the laminated sheets are cut to form the front panel and the rear panel, the laminated film on an inner face of the front panel and on an inner face of the rear panel; for example front panel 202 with laminated film 220 on inner face 202C as shown in FIGURE 2B , and rear panel 204 with laminated film 220 on inner face 204C as shown in FIGURE 2A .
  • a bubble wrap liner is attached to inner faces 202C and 204C of front panel 202 and rear panel 204, respectively.
  • the tamper-resistant envelope by joining the front panel to the rear panel along three seams, forming a pocket between the panels; for example, envelope 100 formed by joining front panel 102 with rear panel 104 along seams 103, with pocket 107 formed between the panels.
  • the tamper-evident seam by perforating or embossing symbols in the seams; for example, symbols 116 and 118 in seams 103 as shown in FIGURE 1A .
  • the flap optionally prepare the tamper-evident viewing windows in the flap; for example, windows 321 in flap 306 as shown in FIGURE 3 .
  • tamper-resistant adhesive to the flap and cover the adhesive with a removable strip so as to avoid inadvertent adhering of the adhesive or inadvertent tampering with the adhesive; for example, adhesive 114 applied to flap 106 and covering a substantial area of the flap between fold line 108 and distal end 106A, and removable strip 112 placed over that adhesive, as shown in FIGURE 1A .
  • markings to the envelope panels; for example flap sealing line 110 on front panel 102 shown in FIGURE 1A , and markings 422 - 426 on front panel 402 and markings 428 on rear panel 404 as shown in FIGURES 4A and 4B .
  • composition or method may include additional ingredients and/or steps, but only if the additional ingredients and/or steps do not materially alter the basic and novel characteristics of the claimed composition or method.
  • a compound or “at least one compound” may include a plurality of compounds, including mixtures thereof.
  • range format is merely for convenience and brevity and should not be construed as an inflexible limitation on the scope of the invention. Accordingly, the description of a range should be considered to have specifically disclosed all the possible subranges as well as individual numerical values within that range. For example, description of a range such as from 1 to 6 should be considered to have specifically disclosed subranges such as from 1 to 3, from 1 to 4, from 1 to 5, from 2 to 4, from 2 to 6, from 3 to 6 etc., as well as individual numbers within that range, for example, 1, 2, 3, 4, 5, and 6. This applies regardless of the breadth of the range.
