A dispenser for rolls of wound film is disclosed, as well as a method of manufacturing such a dispenser. The dispenser includes a trunk to which a lid is hingedly attached. First and second end walls of the trunk include retainers adapted to penetrate into hollow ends of a roll of wound film disposed within the trunk. The first and second retainers include multiple flaps which are locked into a penetrating position. The multiple flaps may include first and second parallel wing flaps which are pushed inwardly by a locking flap. The combined flaps may be locked into position by frictional engagement of the locking flap in notches provided in the first and second wing flaps. By penetrating the first and second ends of the roll, the roll is reliably held within the trunk, and less susceptible to being inadvertently pulled from the carton during dispensing of the film.
