摘要：
A dispenser includes a housing having a sidewall with first and second axial ends. A container has first and second end portions with the second end portion engaged with the housing such that the container extends from the first axial end of the housing. A plunger having first and second sides is disposed in the interior cavity of the container. The interior cavity of the container and the first side of the base cooperatively define a product cavity. The interior cavity of the container and the second side of the base cooperatively define an air cavity. A valve mechanism is in engagement with the second end portion of the container. The valve mechanism includes a nozzle defining an orifice and an accumulator defining a pumping chamber. The pumping chamber is adapted to receive a portion of the product in the container. A piston is selectively slidable in the pumping chamber.
