Abstract
Abstract A plastic, integrally formed caddy comprising a rear panel, a base, a front panel, a pair of side panels, and hinge lines for joining the panels and the base together. Channels on the base and the rear panel seat the edges of the side panels for proper alignment therebetween. Locking tabs and guiding tabs at the free ends of the side panels fit into slots in the rear panel to hold the caddy in erected position. One side panel has two spaced projections for holding a writing implement. Suspension means are integrally formed within a recess in the rear panel of the caddy. After the caddy has been erected, the suspension means are severed from the rear panel and are secured to a flat surface. The caddy is then engaged with, and suspended from, said suspension means.
