<p>The pasty material dispenser comprises a tubular container in which a piston slides under the action of a rotary component so as to discharge the material through a nozzle at one end. The nozzle is mounted on a tubular portion coaxial with the axis of rotation of the component and passing through the top end wall, being connected to the vessel interior by passages in a cap above the top end wall. The cap extends to the container sides. The cap (13) constitutes the rotary component (D), and it can be arranged to snap into engagement with a central aperture (11) in the top wall (7).</p> |
