ABSTRACT:
(U) FIELD OF THE INVENTION
The present invention relates, in general, to stock material or miscellaneous articles and, in particular, to a structurally defined web or sheet.
BACKGROUND OF THE INVENTION
For some items, it is important to know whether or not they were tampered with (e.g., evidence in a criminal trial, food, medicine, a ticket). One way of indicating whether or not an item was tampered with is to place a label on the item that would be visibly and irreversibly altered if disturbed. Such a label is often referred to as a tamper-evident label.
U.S. Pat. No. 4,738,472, entitled “THERMOSENSITIVE LABEL RENDERED UNUSABLE BY REMOVAL FROM ITS FIRST APPLICATION” discloses a tamper-evident label that includes a water-activated adhesive and a thermosensitive dye. The present invention does not include either a water-activated adhesive or a thermosensitive dye. U.S. Pat. No. 4,738,472 is hereby incorporated by reference into the specification of the present invention.
U.S. Pat. No. 5,319,475, entitled “TAMPER RESISTING HOLOGRAPHIC SECURITY SEAL,” discloses a tamper-evident label that includes an optical diffraction pattern that undergoes an irreversible change if tampered with, heated, or chilled. The present invention does not include an optical diffraction pattern. U.S. Pat. No. 5,319,475 is hereby incorporated by reference into the specification of the present invention.
U.S. Pat. No. 5,411,295, entitled “TAMPER EVIDENT LABEL,” discloses a tamper-evident label that includes water-soluble and water-insoluble indicia or graphics. The present invention does not include water-soluble or water-insoluble graphics. U.S. Pat. No. 5,411,295 is hereby incorporated by reference into the specification of the present invention.
U.S. Pat. No. 5,979,357, entitled “EVIDENCE SEALING TAPE WITH FINGERPRINT IDENTIFICATION ZONE,” discloses a tamper-evident label that includes an identification portion for receiving a fingerprint. The present invention does not include an identification portion for receiving a fingerprint. U.S. Pat. No. 5,979,357 is hereby incorporated by reference into the specification of the present invention.
U.S. Pat. No. 6,149,203, entitled “TAMPER-EVIDENT CLOSURE SEAL,” discloses a tamper-evident label that includes an imprinted pattern of adjoining matte and high-gloss areas. The present invention does not include an imprinted patter with adjoining matte and high-gloss areas. U.S. Pat. No. 6,149,203 is hereby incorporated by reference into the specification of the present invention.
U.S. Pat. No. 6,303,202, entitled “SECURE STICKER AND INTEGRATED LABEL/FORM,” discloses a tamper-evident label that includes a paper ply and printed matter sealed in a resin and a liner ply that defines a label portion and a removable portion. The present invention does not include a paper ply, printed matter, a resin, or a liner ply that defines a label or a removable portion. U.S. Pat. No. 6,303,202 is hereby incorporated by reference into the specification of the present invention.
U.S. Pat. No. 6,326,071, entitled “REVERSE THERMAL LABEL,” discloses a tamper-evident label that includes a thermally-imprintable color producing layer. The present invention does not include a thermally-imprintable color producing layer. U.S. Pat. No. 6,326,071 is hereby incorporated by reference into the specification of the present invention.
SUMMARY OF THE INVENTION
It is an object of the present invention to indicate tamper of the label of the present invention if the label is subjected to one of a plurality of tamper techniques.
It is another object of the present invention to include a plurality of adhesive types on the label of the present invention that are sensitive to different conditions.
The present invention is a tamper-evident label that includes a substrate, a plurality of pressure-sensitive adhesives applied to the substrate in user-definable patterns, and a release sheet.
The tamper-evident label is applied to an item of interest by removing the release sheet and pressing the adhesive-side of the label against the item. The adhesives are sensitive to different conditions under which someone might attempt to remove the label. If someone were to attempt to remove the label intact under one of the conditions for which the adhesives are sensitive, the substrate would fracture, rendering the label un-useable as an intact label and, therefore, defeating any attempt to remove the label, tamper with the item, and reseal the item with the label to avoid detection.
