Abstract

A spray head (1) with a nozzle insert (2) for atomizing a fluid, which tends to gum up or harden, from a reservoir, wherein the nozzle insert (2) is substantially designed as a hollow cylinder (3) that is open on one side and has, on the other side, a nozzle opening (4) towards the outside, and the nozzle insert (2) is connected to a nozzle insert receptacle (5), which has a channel (6) for the fluid, wherein the channel (6) corresponds to the nozzle opening (4). The nozzle insert (2) consists of an elastic material (7) and, in this manner, is connected to the nozzle insert receptacle (5) so that an external, free section (8) of the nozzle insert (2) along with the nozzle opening (4) is at least partially manually compressible and/or is designed to be manually bendable from its standby position (R), whereby hardened resin residue (12) can be removed from the nozzle opening (4).
