Abstract
A removable insert and a spray nozzle which includes the removable insert and a nozzle cap. The removable insert has a base member and a protruding member. The nozzle cap has an annular flange which delimits an interior locating surface for the insert. The flange extends radially and ends with an internal extremity which defines a planar spray opening. When in use, the base member is housed within the nozzle cap whilst the protruding member projects outwardly and stands proud of the planar spray opening.
Claims26
-27. (canceled)
A spray nozzle having a downstream end portion with a smooth exterior contour, the spray nozzle including:
- a removable insert having a base member and a protruding member, the base member being integrated with the protruding member and having an external face;
- a nozzle cap with an annular flange which delimits an interior locating surface for the insert, the flange extending radially and ending with an internal extremity which defines a planar spray opening;
- and
- wherein the base member is housed within the nozzle cap whilst the protruding member projects outwardly, the protruding member stands entirely proud of the planar spray opening, the external face of the base member abutting the interior locating surface so as to form a tight seal between the annular flange and the removable insert, the smooth exterior contour transitions from the annular flange with an exterior surface which curves towards the extremity to the external face of the protruding member in a seamless fashion.
A removable insert for fitting into a nozzle cap of a spray nozzle having a downstream end portion with a smooth exterior contour, the insert having a base member and a protruding member, the nozzle cap having an annular flange which delimits an interior locating surface for the insert, the flange extending radially and ending with an internal extremity which defines a planar spray opening;
- wherein the base member is housed within the nozzle cap whilst the protruding member projects outwardly, the protruding member stands entirely proud of the planar spray opening, the protruding member includes an exposed surface which travels beyond the planar spray opening, the exposed surface being either linear and inclined to the planar spraying opening at a constant angle or converging curvedly to form a neck-shaped protruding member, the exposed surface of the protruding member is adapted to transition to the annular flange having an exterior surface which curves towards the extremity in a seamless fashion so as to form the smooth exterior contour.
