<p>The dispenser for washing powder, and especialy for a mixture of soap powder and sawdust, incorporates a storage compartment, pref. made of polycarbonate, for the powder, and a dispenser valve which is operated by means of a press-button and a spring. Two valve housings spaced apart from each other determine, by the distance between them, the quantity of powder to be discharged. At least one of the valves has a rim all round resting against side of the housing acting as a seal. The two valves are in one piece with two edges separated by a dispensing groove. The valves slide axially along a rod.</p> |
