Abstract
Abstract A dispenser for elongate articles, such as pencil leads, comprising a rectangular housing, open at one end, and divided into upper and lower chambers by an intermediate wall. Downwardly and upwardly projecting sills are formed on the upper and lower walls of the housing at the one end, to define a discharge aperture for each chamber. A slider openably closes the two apertures, the sill of the lower chamber preventing a lead sliding from the lower chamber, when the dispenser is tilted, while a lead from the upper chamber can slide out.
