Abstract (en)
A device (1) for dispensing a non-fluid chemical product can be made without the need for a spray head. This device is of the kind where the product is dispensed as a dosing liquid comprising a solution and/or dispersion thereof in a solvent, wherein the device is separated by a liquid-pervious screen (10), into an upper chamber (8) in which the product is to be held, and a lower chamber (14) provided with an inlet (14a) for the solvent and an outlet (18) for the dosing liquid. This is achieved by virtue of the inlet being connected to a mouth (16) for receiving the solvent in free space, whereby the solvent can flow into and fill the lower chamber to a level where it permeates the screen to take-up the product thereabove, whereafter it flows back into the lower chamber to exit via the outlet as the dosing liquid.
