An elastic stretchable lid capable of absorbing moisture is revealed. The elastic stretchable lid includes a lid body and a hollow cap. The lid body made of soft and elastic materials is fit on an opening of a container while the hollow cap is arranged at a center of the lid body and provided with at least one air hole on a bottom thereof, a moisture-absorbing member mounted therein, and a moisture measurement unit arranged at the top thereof. Thereby the lid can be applied to different sizes of containers for closing openings and absorbing moisture to keep inner space of the container dry and prevent objects stored in the container from deterioration or mold growth. The reuse of containers protects the environment. Users can learn saturation degree of the moisture-absorbing member easily by the moisture measurement unit and further replace or regenerate the moisture-absorbing member.

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.
