A tamper-indicating label to be applied to a container. The label is longer than the circumference of the container, so that the label can be wrapped around the container and adhered to itself in an overlap area. The label includes a tamper-indicating mechanism in the overlap area irreversibly indicating if the label has been separated in the overlap area after initial application of the label to the container. The mechanism may be (1) an adhesive bond in the overlap area that is stronger than the label stock in the overlap area, (2) a line of weakening in the label, and/or (3) a frangible material, an adhesive, and/or printing that fractures and/or separates when the overlap area is opened.

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows: 1. A labeled container comprising: a container having a sidewall with a circumference; a label wrapped about said sidewall, said label having a front surface and a back surface and a length greater than said circumference, said label having a container portion and an overlap portion along said length, said container portion and said overlap portion abutting one another, said overlap portion overlapping said container portion; and a single pressure-sensitive adhesive on and extending substantially the full length of said back surface of said label continuously through said container portion and said overlap portion, said adhesive releasably adhering said container portion to said sidewall, said adhesive adhering said overlap portion to said container portion and providing a bond stronger than said label thereby creating a tamper indicating means for indicating whether said overlap portion has been separated from said container portion after said label has been applied to said container. 2. A labeled container as defined in claim 1 wherein said tamper indicating means further includes at least one of a frangible material and printing between said overlap portion and said container portion and adapted to at least one of fracture and separate onto both of said portions when said portions are separated. 3. A tamper revealing label comprising: a label having a container portion and an overlap portion adapted to overlie and adhere to said container portion when said label is wrapped about a container; and a single pressure-sensitive adhesive including a first adhesive zone on said container portion adapted to releasably adhere said container portion to the container and a second adhesive zone between said overlap portion and said container portion adapted to permanently adhere said overlap portion to said container portion when said label is wrapped about the container, said adhesive extending substantially the full length of said label and being continuous through said first and second adhesive zones, the bond provided by said adhesive being stronger than said label, whereby said label is at least one of deformed and destroyed when said overlap portion is separated from said container portion to provide an irreversible indication of the separation of said overlap portion from said container portion. 4. A tamper revealing label as defined in claim 3 wherein said label further includes at least one of a frangible material and printing that at least one of fractures and separates onto the two portions when the overlap portion is separated from the container portion. 5. A method of producing a container with tamper-revealing labeling comprising the steps of: providing a label having a front surface and a back surface, said label having a single pressure-sensitive adhesive on said back surface and having a length greater than the circumference of the container, the adhesive extending substantially the full length of the label; wrapping the label around the container overlapping itself, thereby creating an overlap area, the adhesive extending continuously through said overlap area and the remainder of the label; and releasably adhering the label to the container as the label is wrapped around the container and permanently adhering the label to itself in the overlap area, said permanently adhering step including providing a tamper indication mechanism in the overlap area, whereby the label irreversibly indicates whether the label has been separated in the overlap area after the label has been applied to container. 6. A method as defined in claim 5 wherein the tamper indication mechanism is adapted to cause the label to be deformed when the label is separated in the overlap area. 7. A method as defined in claim 6 wherein the adhesive in the overlap area is stronger than the label, thereby creating the tamper indication mechanism. 8. A method as defined in claim 5 wherein the tamper indication mechanism includes at least one of a frangible material and printing that at least one of fractures and separates onto the two label portions when the label is separated in the overlap area.
