1. A method of maintaining or preserving a product that is sensitive to an environmental trigger, the product being situated in a container having a first cavity and a second cavity, the product being stored in the second cavity, the container further having a utensil that is usable for removing an amount of the product from the second cavity and that is releasably attached to a housing defining the first cavity, the first cavity being devoid of any of the product while the utensil is releasably attached to the housing, the utensil comprising a concave product removal portion and a handle portion extending from the product removal portion, the utensil enclosing the first cavity while the utensil is releasably attached to the housing, the method comprising:
releasing and removing the utensil from the housing and thereby unshielding an active agent that is housed in the first cavity, the active agent being structured to reduce exposure of the product to the environmental trigger, the utensil retaining its original shape as it is released and removed from the housing; and
exposing the product housed in the second cavity to the active agent, thereby reducing exposure of the product to the environmental trigger in order to maintain or preserve the product.
