IT1276560B1 - Sponge dispenser with intercommunicating chambers - Google Patents

Abstract

The dispenser, made from a hard material, rectangular in shape, is divided into three chambers by two internal plates, drilled at the base. In the central chamber is a sponge, cut to a parabolic shape, to cause various levels of humidity. Now, the liquid poured into the two side chambers through the semicircular holes in the respective covers, by the well-known principle of communicating vessels, exerts on the sponge a constant physiological water tension. Unlike what is found with traditional dispensers, the sponge remains in contact with the liquid without a continuity solution. It is sufficiently absorbent and recovers spontaneously, by cybernetic reflex, the amount of liquid dispensed. Useful for practical purposes, such as moistening stamps, it will be more so for reasons of hygiene. Millions of clerks, operators and shopkeepers will stop using saliva on their fingers. <IMAGE>
