A single one piece blank is folded over to form a gravity feed tube for point of sale display of products such as disposable cameras packaged in boxes with display cards. The rear wall has two overlying panels, the outer one of which has openings in a linear array and the other inner panel has locking tabs aligned with the openings. The tabs are pulled through the outer panel openings. The tabs have wings which engage the outer panel to lock the outer panel to the inner panel locking the blank in the tube configuration. A set of flaps in the bottom region form a feed opening and shelf for the product to be dispensed. A locking tab locks the bottom flaps closed. The side walls, front and rear walls have overlapping interior panel flaps at the top of the tube channel to provide a finished appearence to the interior at the open top.
