1. A package that includes:
- a container having an open end;
a closure closing the open end of the container; and
a sensor carried by at least one of the container or the closure to detect at least one of pressure in the container or weight of product in the container, wherein said sensor is responsive to a change associated with at least one of pressure in the container, weight of product in the container, or the closure relative to the container, to modify an optical characteristic associated with the package to indicate that the package has been opened and/or that product has been dispensed from the container, and wherein a portion of the package exhibits an initial state of the optical characteristic, and then exhibits another state irreversible to the initial state after the package has been opened and/or relieved of at least some of the product in the container.
