A carton blank (2) having an outer layer of a relatively rigid material, a first inner layer (120) of a relatively rigid material superposed over a portion of the outer layer and a second inner layer (140) of a relatively flexible layer of a fluid impervious material is provided with first (86) an d second (92) weakened portions so that, after a carton (180) has been formed from the carton blank (2), filled with a desired material and sealed, the first weakened portion (86) may be broken to form a flip top lid (282, 382, 482) which when moved in an arcuate path will gradually sever the second weakened portion (92) to form an opening in the carton (2) so that an amount of the desired material may be removed from the carton (2). The carton (2) also may include a feature wich allows the flip top lid (282, 382, 482) to b e securely re-closed after initial opening of the lid (282, 382, 482).
