CONTAINER AND METHOD OF MAKING A CONTAINER

摘要

A container [110] includes a hydrochromic material [120] associated with at least a portion of the wall [112] of the container. The hydrochromic material may be visible from the exterior of the container. The hydrochromic material may have a first appearance when in a dry form and a second appearance, different from the first appearance, when the hydrochromic material becomes hydrated.
