Packaging for a can containing ground roasted coffee packed under atmospheric pressure and having a flexible peel-off lid which is vented to allow the escape of a buildup of carbon dioxide gases. A spacing structure prevents the vent valve in the lid from being closed by contact with the plastic overcap. The spacing structure may include bosses on the overcap which engage the vent valve or a pocket in the overcap which allows the flexible lid to reach a maximum height without engaging the overcap. A permanently opened passageway may be provided between the plastic overcap and the rim of the can to further facilitate the escape of carbon dioxide.

A method for triggering an oxygen scavenging composition for use in packaging an oxygen sensitive article includes the steps of providing an oxygen scavenging composition comprising an oxidizable organic compound and, optionally, a transition metal catalyst, and exposing the composition to a source of pulsed light wherein each pulse has a duration of between 1 microsecond and 1 millisecond, a frequency of between 0.1 to 100 Hertz, and a total intensity of at least 350 mW/cmso that each pulse provides the composition with a dose of UV light of at least 0.1 J/cmso as to provide a triggered composition. The triggered composition can be applied to an article so as to provide an oxygen scavenging package. An apparatus and packaging system are also disclosed.

Method and apparatus for triggering oxygen scavenging composition with pulsed light

Novel articles and packages are disclosed. Disclosed is the non-invasive use of a luminescent compound to detect and measure concentrations of oxygen dissolved in solids, particularly polymeric materials present in multi-layered packaging materials. The measurement is made independent of the oxygen concentration of the surrounding atmosphere. The invention is especially useful as a quality assurance check to verify oxygen scavenger activation during the assembly of modified atmosphere and vacuum packages. A solid article includes a film including an oxygen barrier layer; and a layer including an oxygen scavenger; and a patch including an oxygen barrier; and an oxygen indicator including a luminescent compound; wherein the patch is adhered to the film; and wherein the oxygen indicator is disposed between the oxygen barrier of the patch, and the oxygen barrier of the film. A package, and a bottle, each having the oxygen indicator, are also disclosed.
