Abstract: Disclosed is a shower head dispenser for bath oil and the like which includes a body member with an axial bore adapted for insertion between a shower line and a shower head. The body member has two longitudinally spaced apertures or transverse bores in its side wall which communicate between the axial bore and a detachable oil container. It has a dam extending transversely across the bore. One of the apertures intercepts the axial bore at the crest of the dam, and the other aperture intercepts the axial bore upstream of the dam. The oil container has an integral valve stem thereon which seats in the end of the downstream transverse bore, and metering is achieved by rotation of the container. When water passes through the axial bore of the body member, the greater pressure at the upstream bore or aperture forces oil out of the container through the downstream bore or aperture into the axial bore at the dam, where it mixes with water enroute to the shower head.
