A dispenser for use in a self select retail environment and adapted for controlled delivery of packages has a dispensing member (6; 56) which is manually actuated so that individual packages (2) are taken in turn from a stack of packages stored in the dispenser and presented for removal when the dispensing member is in its open position. Return movement of the dispensing member (6, 56) from the open to the closed position under the influence of a return spring (12; 64; 86) is retarded by a rotary damper (20) driven by a toothed rack (17; 67; 80) so that the rate at which packages can be removed from the dispenser by repeated actuation of the dispensing member is restricted. In one embodiment the packages are stacked vertically and the dispensing member comprises a drawer (6) which is guided for horizontal sliding movement (Figs 1-16 and 28-35). In an alternative embodiment the packages are stacked horizontally and the dispensing member is a door (56) which pivots about a horizontal axis between an upright closed position and a forwardly inclined open position (Figs 17-27). The dispenser allows controlled loading of packages, but removal of packages by reversal of the loading procedure is prevented. Thus, a series of loading slots (32) may be formed along the stack container (Fig 7) or barbs (42; 45) which flex or move to allow downward movement and which block upward movement can be disposed along a loading slot (41) (Figs 10 and 11). |
