DESCRIPTION:
BRIEF SUMMARY
The invention relates to powdered-soap dispensers for sprinkling powdered soap or the like onto the hand in an apportioned manner.
For reasons of hygiene, instead of bars of soap, use is often made of liquid soap from various designs of liquid-soap dispensers. In washrooms in the workplace and public places, the use of liquid-soap dispensers is customary since regulations prohibit the use of bars of soap. Occasionally, use is also made of devices for scraping off fragments from a piece of soap, as a result of which contact of the piece of soap with the hand is ruled out.
As a result of the more favourable properties, for example the ability to break down readily, it would be preferable to use powdered soap; however, there is an apparent lack of practical dispensers which can be produced cost-effectively for this purpose. The use of powdered soap would also be recommendable because, in recent years, new production methods have improved the properties of powdered soap, in particular the sprinkling characteristics thereof.
The hitherto known designs according to U.S. Pat. No. 2,681,169, FR 934 501, DE 17 79 727 and DE 26 46 882 are dispensers, but not of the apportioning variety, i.e. upon actuation a closure is opened and powdered soap runs out until the opening is closed. High outlay is often required here in order to prevent bridge formation of the powdered soap. The designs are complicated and expensive.
The design according to DE 35 11 507 is suitable for dispensing relatively large quantities in an apportioned manner and is intended for washing powder for washing machines. A disadvantage of the design is that, as the closing piston is lifted from the bottom position into the top position, both openings are open, as a result of which apportioning is inaccurate and it is not possible for small quantities to be apportioned.
The object of the invention was to provide a powdered-soap dispenser which does not have the listed disadvantages of the prior art and is just as straightforward to handle as the known dispensers for liquid soap.
This object is achieved by a novel powdered-soap dispenser for sprinkling powdered soap or the like onto the hand in an apportioned manner which comprises a dispenser part, a container and a mount, it being possible for the dispenser part to be integrated in the container or to be separable.
The dispenser part has at least one sprinkling hole, as well as an apportioning lever. For its part, the apportioning lever has an actuating surface and at least one apportioning closure piston.
The apportioning closure pistons project through the sprinkling holes into the interior of the container. Furthermore, in the direction towards the interior of the container, the apportioning closure piston has integrally formed on it a web, and, following this, a closure part, it being the case that the closure part, on the side located on the web, is of spherical or conical shape and, in the dispensing position, the closure part closes the sprinkling holes from the inside. This produces, between the apportioning closure piston and closure part, a cavity which determines the volume of powdered soap which is to be dispensed when the dispenser is actuated. Accordingly, the wall height of the sprinkling holes is also derived from the volume of the cavity.
Finally, the apportioning lever has an integrally formed restoring spring.
The sprinkling holes are open at the top and closed at the bottom in the basic position of the apportioning lever and, following actuation of the apportioning lever, are closed at the top and open at the bottom in the dispensing position.
The actuating surface on the apportioning lever is preferably arranged such that, when the dispenser is actuated by the thumb or fingers of one hand, the powdered soap which is to be apportioned falls onto the palm of the same hand.
The diameters of the apportioning closure pistons are usually greater than the diameter of the sprinkling holes, in order to ensure closure of the sprinkling holes in the basic position.
