ABSTRACT:
A plastic squeeze container for dispensing an appropriate solution is disclosed. The top of the container includes a 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 an aperture in the container top adjacent the stem. A small central aperture in the seal where it overlies the closing of the stem, enables dispensing contents from the container when the container is squeezed, as the resulting internal pressure causes the seal to balloon slightly away from the stem and permit passage of the solution from the container through the container aperture and through the seal central aperture. When the external pressure is removed, the seal resiliently retracts against the stem and closes the container. A screw-on cap is also provided which when attached to the container creates a seal which isolates the aperture at the top of the container and prevents unintentional dispensing of container contents due to accidental squeezing of the container. Finally, the valve assembly includes a peripheral seal which prevents air from leaking in.
