<p>A hand-held paste dispenser (1) is disclosed which has a discharge means (3) actuated by a cap (5) for the dispenser. For dispensing, the cap (5) is removed from the discharge end and pushed over the rear portion, in which position a key (13) engages a recess (10) in a threaded drive spindle of the discharge means. The cap is then rotated to dispense paste and rotation is limited by stops (16,17) so that a metered "measure" may be dispensed. The dispenser may also include a paste applicator head (32) to form a reservoir toothbrush. Because engagement between the cap and discharge means is required, accidental discharge resulting in blocking of the outlet and lack of cleanliness is avoided and the dispenser is tamper-proof for young children. Further, the dispenser allows control of the amount discharged which is important for avoiding waste and in discharging an exact required amount of paste.</p> |
