Abstract
Abstract A collapsible terrarium assembly which is inflatable to assume a desired configuration for transparently housing a potted plant or other article to be protectively enclosed. The structure is constituted by a disc-like base and a dome attachable thereto. The dome is formed by an open, flexible plastic envelope whose rim is secured to a coupling ring which is joinable to the base to form a hermetically-sealed enclosure, the envelope including a valve for inflating the dome.
