Abstract
Abstract A container for dispensing sheet material from a roll received interior of the container, the container having a removable end wall for insertion of a roll of sheet material such as film. The container has a slot through a wall portion thereof from which the sheet material can be dispensed, the slot being formed by inwardly bent portions of the material which forms the container body. Removable seal members carried by the inwardly bent portions are coated with a fabric-like material which substantially closes the slot to restrict entrance of light to the interior of the container.
