TAMPER-RESISTANT ENVELOPE

Description

FIELD AND BACKGROUND OF THE INVENTION

[0001] The present invention, in some embodiments thereof, relates to envelopes and, more particularly, but not exclusively, to tamper-resistant and tamper-evident envelopes.

[0002] 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. Usually, 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. In some instances, transport of the envelope may be done by a postal service. In other instances, a private delivery service such as a courier may be used. Regardless of who transports the envelope, 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.

[0003] 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.

[0004] US Patent No. 5,727,686 "TAMPER-EVIDENT SECURITY ENVELOPE", relates to "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."

[0005] US Patent No. 5,918,983 "SECURITY ENVELOPE", relates to "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."

[0006] US Publication No. 2008/0156855 "SECURE ENVELOPE AND METHOD FOR SECURING INFORMATION", relates to "A windowed envelope is disclosed comprising: a first panel with an interior and an exterior side; a second panel attached to the first panel to define an interior portion having opposite side edges, a closed edge portion and an opening portion opposite the closed edge portion to provide access to the interior portion of the envelope; and a flap for sealingly adhering to an exterior surface of the first panel. 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. The window comprises a reducible dye and a microencapsulated reducing agent, which is adapted to irreversibly change to a transparent window upon heating the non-transparent window to a temperature above room temperature."

[0007] Additional background art includes US5,474,818; US4,566,627; US2,230,849; DE344106; and in particular US 2005/0116014 apart from BE384979.

DESCRIPTION OF EMBODIMENTS OF THE INVENTION

[0023] The present invention, in some embodiments thereof, relates to envelopes and, more particularly, but not exclusively, to tamper-resistant and tamper-evident envelopes.

[0024] An aspect of some embodiments of the present invention relates to a tamper-resistant envelope formed from joining together a first panel and a second panel along three edges to form a pocket between the panels, the first panel extends beyond an opening to the pocket and includes an adherable flap which is adapted to be folded and adhered to both the first panel and the second panel for sealing the pocket. Adhering of the flap to both the first panel and the second panel substantially seals the opening of the pocket. Sealing the opening of the pocket prevents access to the opening (now sealed) from any direction using mechanical means without noticeable damage being caused to the envelope. This substantially prevents tampering with contents placed inside the pocket without the tampering being evident (tamper-evident). Optionally, a tamper-evident feature in the envelope makes the envelope substantially tamper-resistant as a person wishing to tamper with the envelope will most probably desist from such action if the tampering will be evident. The mechanical means may include an object (tool) suitable to be inserted under a flap for opening the flap. Optionally, the mechanical means may include a use of force for pulling the flap.

[0025] In some embodiments of the present invention, the flap is adhered to the first panel and the second panel using a tamper-evident adhesive which provides a visual indication when the adhesive has been tampered with. Optionally, the adhesive may include a glue and provides an indication of an attempt having been made to change the adhesive properties of the glue, for example by trying to heat the glue to dissolve it, and/or by trying to freeze the glue to cause it to brittle and break. Optionally, the glue changes a color when exposed to temperatures which change its adhesive properties. Optionally, the adhesive properties of the glue are maintained throughout a temperature range from -45°C to 100°C. Optionally, the adhesive properties of the glue are maintained for temperatures above 100°C and/or below -45°C. Additionally or alternatively, the tamper-evident adhesive includes an adhesive tape. Optionally, the adhesive tape is a double-sided adhesive tape. Optionally, the tamper-evident adhesive includes an adhesive film. Optionally, the adhesive tape is a tamper evident tape model 120/87 produced by Label Tech Ltd, Israel, and includes PVC 50µm and an acrylic adhesive. Optionally, a visual message such as, for example, the word "VOID", is formed in the tamper-evident adhesive when tampered with. Additionally or alternatively, the flap may include a tamper-viewing window through which evidence of tampering with the tamper-evident adhesive may be viewed. Optionally, the visual message is displayed through the window. Optionally, the tamper-evident adhesive may include one or more symbols (may include characters, letters, numbers, logos, etc.) invisible to the naked eye and which serve to corroborate that the adhesive has not been replaced.

[0026] In some embodiments of the present invention, the first panel and the second panel are each laminated on an inner face with a material film resistant to a wetter or a wetting agent which may be applied to the envelope for attempting to make the panels temporarily transparent. The laminated inner faces, which are on the side of the first panel and the second panel forming the pocket, are adapted to provide a degree of opacity which substantially prevents viewing of the contents inside the envelope when the wetter is applied to outer faces of the panels (optically opaque). Optionally, the laminate film is a plastic film and includes a polymeric material such as, for example, polyethylene, polypropylene, or nylon, or any combination thereof. Optionally, the laminate film is a carbon-based laminate. Additionally or alternatively, the laminated film prevents liquids from reaching the contents inside the pocket (water-resistant). The laminate film is susceptible to the wetter and changes a color when exposed to the wetter. Additionally or alternatively, the laminate film is adapted to bloom through the panels when the wetter is applied to the panels and migrates through the panels to the laminate film. Laminating of the inner faces may be done by methods known in the art, and may include cold lamination. Optionally, hot lamination is used. Optionally, a bubble wrap liner is attached to the inner face of each panel for providing mechanical protection to the contents of the envelope (inside the pocket) from impact.

[0027] In some embodiments of the present invention, the three edges along which the first panel and the second panel are joined together to form the pocket each include a tamper-evident seam. The tamper-evident seam includes one or more perforated symbols along a major portion of the seam such that, if the envelope is opened along the edge comprising the seam, at least one of the symbols will be damaged. The damaged symbol may then be readily detected when the envelope is checked for tampering. Optionally, use of the tamper-evident seam is restricted to one of the three edges. Optionally, use of the tamper-evident seam is restricted to two of the three edges. Optionally, tamper-evident symbols are used on the flap. Additionally or alternatively, the tamper-evident seam is embossed with the one or more symbols. Optionally, the tamper-evident seam (and/or the flap) includes at least one dissimilar symbol. Optionally, the one or more symbols are all similar.

[0028] In some embodiments of the present invention, the tamper-evident seam may include an electrical conductor which extends along the seam and is connected to a power source in the envelope. Optionally, the power source is an external source which induces a current in the electric conductor by generating an electromagnetic field (EM) to which the envelope is exposed. Optionally, the electrical conductor includes an electrically conducting paint and/or film. When the seam is opened (which may include being cut), an open circuit is created in the electrical conductor which is detected by a sensor in the envelope. Optionally, the power source includes the sensor. Additionally or alternatively, a visual warning is displayed in the envelope by a chemically reactive display responsive to the open circuit (for example, a change in color of a paint or coating as in electrochromic paints and/or thermochromic paints). Optionally, the visual warning is displayed through a thin film LCD. Optionally, the warning is displayed through a clock visibly included in the envelope which displays the time and date when the open circuit was created. Optionally, the clock is activated by the tampering and counts a period of time since its activation (a counter). Optionally, an audible alarm is activated.

[0029] In some embodiments of the present invention, the electrical conductors are arranged in the envelope such that an open circuit occurs when the pocket is opened. Optionally, the conductors are arranged along the flap and the second panel such that separating the flap from the second panel results in an open circuit.

[0030] In some embodiments of the present invention, the envelope includes a Radio Frequency Identification Device (RFID) tag for local reading of the envelope's identification. Optionally, the RFID tag is a passive RFID tag. Optionally, the RFID tag is an active tag. Optionally, the RFID tag is a battery-assisted passive tag. Additionally or alternatively, the envelope includes a GPS (Global Positioning System) device for determining a location of the envelope.

[0031] In some embodiments of the present invention, the panels include paper of thickness ranging from 60 gsm (grams per square meter) to 160 gsm, for example, 60 - 90 gsm, 80 - 100 gsm, 90 - 120 gsm, 120 - 160 gsm. Optionally, the panel thickness is greater than 160 gsm. Optionally, the panels include an 80 gram wood free paper model Hadar Top produced by Israel Paper Co. Ltd, in Israel. Optionally, the panels include outer faces which are laminated. Optionally, the panels are water resistant. Optionally, the panels include a cardboard material. Additionally or alternatively, the panels include a plastic material.

[0032] In some embodiments of the present invention, the envelope may be formed from a single panel which is folded along an edge into two sections forming the first panel and the second panel, the first panel including the extension and the flap. In an exemplary embodiment, the envelope includes two edges which are sealed. Optionally, the sealed edges are along the sides of the envelope. Optionally, the sealed edges include one of the sides of the envelope and a bottom edge opposite the flap.

[0033] Before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not necessarily limited in its application to the details of construction and the arrangement of the components and/or methods set forth in the following description and/or illustrated in the drawings and/or the Examples.
