Abstract
A container for materials having volatile components is constructed to have a substantial transparency. The container includes a tubular housing having first and second closing structures at opposite ends. The housing is formed as a laminate having a relatively thin inner lining of high barrier amorphous nylon for contacting the material having a volatile component and an outer sleeve of low barrier plastic, such as polyethylene teraphthalate. The container is specifically adapted for viscous caulking compounds wherein the first closing structure is an end wall, nozzle and snout assembly and wherein the second closing structure is defined by a movable piston slideably received in the housing interior.
