Abstract
A carton blank and a leakproof carton formed therefrom which carton has an outer enclosure formed from a relatively rigid material and having an openable top portion and a closed bottom portion and a leakproof inner liner having a central body portion secured to an opposed central body of the outer enclosure, a closed bottom and an openable closed top so that after portions of the material in the carton have been removed the top portion and adjacent portions of the inner liner's central body may be separated from the central body of the outer enclosure and folded downwardly to protect the remaining material in the carton. In one embodiment, after all the material has been removed from the carton, the leakproof inner liner may be completely removed from the outer enclosure.
