Abstract

This invention is directed to a dispensing container for solid deodorant and/or disinfectant media, for use in urinals having a flush water system. The chemical dispensing container comprises a generally flat plate or screen having a perforate central portion and a perforate peripheral portion. An imperforate cover overlies the perforate central portion and contains therewithin the solid deodorant and/or disinfectant media. Cooperating fastening means are provided on said imperforate cover and said underlying plate to enable the cover to be releasably engaged to said plate. A lug support means is also provided, affixed to either of said cover or plate, to prevent abutment of the cover to said plate forming thereby a continuous peripheral channel immediately adjacent and below said cover whereby the flush water path of the urinal includes passage of flush water from the underside of the plate upwardly through the central perforate portion thereof into the interior of the imperforate cover, and outwardly through the continuous peripheral channel. In following this path, the flush water contacts the undersurface of the solid deodorant and disinfectant media, dissolves a portion of the same, and as it passes peripherally outwardly through the channel formed between cover and plate, the dissolved deodorant and disinfectant effectively causes deodorant and disinfectant action to occur over a large surface area of the bowl of the urinal surrounding the solid media.

Claims

1. A dispensing container for solid deodorant and/or disinfectant media, for use in urinals, which comprises:

a generally flat plate having a perforate central portion and a perforate peripheral portion;

an imperforate cover adapted to contain therewithin said solid media and being provided with a peripheral flange therearound;

cooperating fastening means on said imperforate cover and said plate for releasably engaging said imperforate cover with said plate in overlying relationship with said perforate central portion of said plate; and

lug means affixed to said plate and lying in abutment with said peripheral flange of said cover thereby prevening abutment of said cover to said plate and forming a substantially continuous peripheral channel immediately adjacent and below said cover whereby the flush water path includes passage of flush water from the underside of the plate upwardly through the central porforate portion thereof, into the interior of the imperforate cover, and outwardly through the peripheral channel formed immediately below said cover.

2. The dispensing container of claim 1 wherein said plate and cover are made of a plastic material.

3. The dispensing container of claim 1 wherein said cover has a domed configuration in side elevation.

4. The dispensing container of claim 1 wherein said lug means has a length which is a minor fraction of the periphery of said cover to form said substantially continuous peripheral channel.

5. The dispensing container of claim 1 wherein said cooperating fastening means includes mating hook and eye members.
