Abstract: A device configured to maintain or preserve products sensitive to environmental triggers, such as moisture or oxygen, can include a lid (24) removably attachable to a body (16) of a container (10) in which the sensitive product (23) is stored. An active agent (12) capable of preventing, or at least slowing, exposure of the sensitive product to the environmental trigger is positioned in or under the lid. A utensil (40) configured to shield the active agent can be removably attached to an underside of the lid and positioned to cover the active agent when the utensil is attached to the lid. Upon removal of the utensil, the active agent is unshielded and, upon exposure to the environment, is activated to absorb or consume at least some of the environmental triggers within the container.
