Reprocess Indicating Device
The present invention provides a secure indicator label device for use on an article or container which includes a visual indicator, tamper-evident and/or anti-counterfeit features. Also provided are methods for indicating whether an article or the contents of a container have been exposed to a particular environment and a method for reducing the likelihood of improper re-use of a single-use article or container.
1 . A label for an article, comprising an indicator capable of undergoing a color change when exposed to a particular environment and an anti-counterfeiting means and/or a tamper-evident means.
2 . The label according to claim 1 , wherein the anti-counterfeiting means is selected from the group consisting of a hologram, an optically variable device and an optically variable image, and wherein said anti-counterfeiting means provide optical effects.
3 . The label according to claim 1 , wherein the tamper-evident means is created by the incorporation of a pattern of release material between the layers of a multi-layer label, wherein such material selectively degrades the chemical bond between the layers so that the label is destroyed if an attempt is made to remove the label from the article.
4 . The label according to claim 1 , wherein the tamper-evident means is created by die cuts in the label that cause the label to segment if an attempt is made to peel the label off of the article.
5 . The label according to claim 1 , wherein the label is part of the construction of the article.
6 . The label according to claim 1 , wherein the environment is selected from the group consisting of moisture, steam, high temperature and a chemical.
7 . The label according to claim 1 , wherein the indicator is an encapsulated dye.
8 . The label according to claim 1 , wherein the article is a single-use device.
9 . The label according to claim 1 , wherein the article is a medical device.
10 . The label according to claim 9 , wherein the article is a single-use device.
11 . The label according to claim 1 , wherein the article is a container or packaging.
12 . The label according to claim 1 , wherein the label is a multi-layer label comprising a transparent top layer, a visually-indicating middle layer and an adhesive bottom layer.
13 . The label according to claim 12 , further comprising a mask positioned between the transparent top layer and the visually-indicating middle layer.
14 . A method for indicating whether an article has been exposed to a particular environment, comprising:
adhesively attaching to the article a label, the label comprising an indicator capable of undergoing a color change when exposed to a particular environment and an anti-counterfeiting means and/or a tamper-evident means; and
visually examining the label for an appropriate color change.
15 . The method of claim 14 , wherein the article is a single-use medical device.
16 . The method of claim 14 , wherein the environment is selected from the group consisting of moisture, steam, high temperature and a chemical.
17 . A method for indicating whether the contents of a container or package have been exposed to a particular environment, comprising:
adhesively attaching to the container or package a label according to claim 1 ; and
visually examining the label for an appropriate color change.
18 . The method of claim 11 , wherein the container is a bottle or a jar.
19 . A method for reducing the likelihood of improper re-use of a single-use device, comprising:
adhesively attaching to the single-use device a label, the label comprising an indicator capable of undergoing a color change when exposed to a particular environment and an anti-counterfeiting means and/or a tamper-evident means;
visually inspecting the indicator label for indication of color change, tampering, and/or counterfeiting; and
disposing of the single-use device if the inspection indicates previous use.
20 . The method of claim 19 , wherein the single-use device comprises a medical device.
