ABSTRACT:
A carton blank having an outer layer of a relatively rigid material, a first inner layer of a relatively rigid material superposed over a portion of the outer layer and a second inner layer of a relatively flexible layer of a fluid impervious material is provided with first and second weakened portions so that, after a carton has been formed from the carton blank, filled with a desired material and sealed, the first weakened portion may be broken to form a flip top lid which when moved in an arcuate path will gradually sever the second weakened portion to form an opening in the carton so that an amount of the desired material may be removed from the carton. The carton also may include a feature which allows the flip top lid to be securely re-closed after initial opening of the lid.
