| 摘要 |
The present invention provides a passive dispenser having dual sections for use in a toilet tank in which a disinfectant solution to be dispensed is stored in one section and substantially isolated from the water in the toilet tank, the section comprising a product chamber having a venting means and a refill/discharge pathway. The refill/discharge pathway is vented to the atmosphere and has an inclined conduit extending downwardly from the top portion of the pathway to the product chamber. Hydrostatic head obtained by use of refill/discharge pathway venting conduit in conjunction with the inclined conduit retards the outflow of solution from said product chamber during quiescent periods. Constriction means in the refill/discharge pathway venting conduit is preferred to provide turbulence during the refill cycle. In the other section of the dispenser, a soluble composition comprising a detergent, deodorant or other additive materials is stored. Both compositions are dispensed into the toilet tank simultaneously when the toilet is flushed.
