A device to air entrain and add liquid soap or some other liquid to the water stream which flows through a shower head. There is a secondary liquid additive passageway leading into a constricted reduced pressure area of the main flow passageway of the shower water. There is a container rotatably mounted in a manner to either shut off flow of the liquid soap or other liquid, or to selectively meter the flow into the main water stream by selectively aligning aspirating air holes with an aspirating air passageway that leads into the secondary passageway.

An apparatus to selectively introduce an additive liquid into a stream of water flowing through a shower head, said apparatus comprising: a. a main housing member defining a first main through passageway for flow of shower water therethrough, said passageway having a reduced flow area passageway portion to create a low static pressure flow area; b. a second dispensing member connected to said housing member and defining a second passageway having an inlet end and an outlet end leading into the low pressure flow area of the first passageway; c. an additive liquid container defining a containing chamber and adapted to be mounted to said second member so that said container can be moved relative to the second member and so that said inlet of the second passageway communicates with the containing chamber with said container being positioned so that there is a gravitational component of flow from said containing chamber to said second passageway; and d. the second member and the container collectively defining selectively operable aspirating air passageway means connecting to said second passageway, said air passageway means being arranged so that relative movement between the container and the second member to selected positions relusts in greater or less air flow through the air passageway means to the second passageway while flow of the additive liquid is maintained through said second passageway, to vary flow of additive liquid through the second passageway to the first main passageway.
