AbstractA plastic squeeze bottle has a dispensing end having a central, closed-ended, cone-shaped portion which serves as a stem or core for a valve assembly which includes an elastomeric seal which overlies and resiliently grips and circumferentially seals around the stem. The seal also covers apertures in the bottle end adjacent the stem. A small central aperture in the seal where it overlies the closed end of the stem, enables dispensing contents from the bottle when the bottle is squeezed, as the resulting internal pressure causes the seal to balloon slightly away from the stem and permit passage of saline solution from the bottle through the bottle end apertures and seal central aperture. When the squeezing stops, the seal resiliently retracts against the stem and closes the bottle. A snap-on overcap assembly has seal control and closure maintenance features to avoid accidental dispensing of bottle contents due to unintentional squeezing of the bottle when the overcap is closed.
