Abstract
Abstract A lightproof film dispenser for a box formed from telescoping box parts. The box parts have adjacent cut-out portions in telescoping wall portions thereof. The dispenser is formed from a housing having a pair of spaced, parallel channels into which are fitted the longitudinal edges of the cut-out portions of the box parts. Each end of the dispenser is cut-away. A top wall of the cut-away portion at one end of the dispenser is at a level which is spaced from that of the corresponding top wall of the cut-away portion at the other end of the dispenser by a distance the same as the thickness of the material from which the box parts are made. This difference in levels of the top walls provides for a light-tight seal.
