<p>Disclosed is a rigid container comprising a wall, the wall comprising: a) a first layer comprising an oxygen barrier having an oxygen transmission rate of no more than 100 cc/m2/24hr at 25 deg C, 0% RH, 1 atm (ASTM D 3985); and b) a second layer comprising an oxygen scavenger and a third layer comprising an oxygen indicator comprising a luminescent compound; or c) a second layer comprising an oxygen indicator comprising a luminescent compound and a third layer comprising an oxygen scavenger; wherein the oxygen indicator is substantially shielded by oxygen barrier layers from oxygen in the environment surrounding the container, and from oxygen in any headspace within the container; and wherein the oxygen indicator comprises all or part of a printed image. Also disclosed is a rigid container comprising: a) a tray comprising a tray flange, wherein the tray comprises an oxygen indicator comprising a luminescent compound; and b) a lidstock comprising an oxygen barrier having an oxygen transmission rate of no more than 100 cc/m2/24hr at 25 deg C, 0% RH, 1 atm (ASTM D 3985); and an oxygen scavenger. Also disclosed is a rigid container comprising: a) a tray comprising a tray liner, and a tray flange, wherein the tray liner comprises an oxygen indicator comprising a luminescent compound, and an oxygen scavenger; and b) a lidstock comprising an oxygen barrier having an oxygen transmission rate of no more than 100 cc/m2/24hr at 25 deg C, 0% RH, 1 atm (ASTM D 3985). Also disclosed is a rigid container comprising: a) a tray comprising a tray liner, and a tray flange, wherein the tray liner comprises an oxygen scavenger; and b) a patch, adhered to the tray flange, comprising an oxygen indicator comprising a luminescent compound, wherein the patch comprises an oxygen barrier having an oxygen transmission rate of no more than 100 cc/m2/24hr at 25 deg C, 0% RH, 1 atm (ASTM D 3985).</p> |
