A dispenser comprises a container for containing fluid to be dispensed and a manually operated reciprocating fluid pump to be secured to the container. The fluid pump includes a pump mechanism, an intake port adapted for fluid communication with liquid contained in the container, an intake liquid flow path providing fluid communication between the intake port and the pump mechanism, a discharge port, a discharge liquid flow path providing fluid communication between the pump mechanism and discharge port, a closure cap portion configured for securing the fluid pump to the container, and a seal portion engageable with the container for providing a fluid-tight seal between the fluid pump and the container. The container includes a neck having a mouth therein for passage therethrough of liquid in the container. The container further includes a flange circumscribing the neck of the container. The closure cap portion comprises a generally annular-shaped skirt, and at least three protrusions extending generally radially inwardly from an inside surface of the skirt. The protrusions are circumferentially spaced from each other along the inside surface of the skirt. The protrusions of the closure cap and the flange of the container are configured for a resilient snap-fit engagement of the protrusions with the generally downwardly facing surface of the flange when the seal portion of the fluid pump is brought into engagement with the container to releasably maintain the seal portion in fluid-tight sealing engagement with the container.

[ What is claimed is:] [18.] A dispenser comprising:a container for containing fluid to be dispensed; anda manually operated reciprocating fluid pump adapted to be secured to the container;the fluid pump including a pump mechanism, an intake port adapted for fluid communication with liquid contained in the container, an intake liquid flow path providing fluid communication between the intake port and the pump mechanism, a discharge port, a discharge liquid flow path providing fluid communication between the pump mechanism and discharge port, a closure cap portion configured for releasably securing the fluid pump to the container, and a seal portion engageable with the container and shaped and configured for providing a fluid-tight seal between the fluid pump and the container;the container including a neck having a mouth therein for passage therethrough of liquid in the container, the container further including a flange circumscribing and extending radially outwardly from the neck of the container, the flange including a generally downwardly facing surface;the closure cap portion comprising a generally annular-shaped skirt, at least one protrusion extending generally radially inwardly from an inside surface of the skirt, the protrusion of the closure cap portion and the flange of the container being configured for a resilient snap-fit engagement of the protrusion with the generally downwardly facing surface of the flange when the seal portion of the fluid pump is brought into engagement with the container to releasably maintain the seal portion in fluid-tight sealing engagement with the container;the closure cap portion further including a first camming surface, and the container further including a second camming surface, the first and second camming surfaces being shaped and configured to engage one another in a manner to cause separation of the protrusion from the flange upon simultaneous application of a radial force against the closure cap and rotation of the closure cap relative to the container, the closure cap portion and container being shaped and configured to permit rotation of the closure cap portion on the container while maintaining the seal portion in fluid-tight sealing engagement with the container when the closure cap is devoid of such radial force.
