Abstract

An inexpensive and disposable dispenser has few parts. The dispenser has a housing with a reservoir of fluid therein. The housing has a valve seat and a valve. The valve is biased in a closed position by resilient spring arms. Each spring arm has a fixed end coupled to the housing and a free end that contacts a rounded or inclined surface of the valve in a location that is offset from a centerline of movement. As the valve moves to an open position, the spring arms flex with the free ends moving apart. When the spring arms straighten and the free ends move closer to each other, the valve is moved to the closed position. The dispenser can be manipulated by a hand or by a massager. A massager imparts vibrations to the valve by way of the housing and the spring arm. The dispenser can be used to work the fluid into an object such as human skin.
