Abstract
The present invention provides a flexible container for dispensing liquids capable of providing precise dosage of the liquid. The container comprises an upper liquid reservoir and a lower liquid reservoir separated by a gasket, a longitudinal tube extending through the gasket and comprising a slot, and a dispensing tip having a longitudinal sleeve extending therefrom that also comprises a slot and is disposed concentrically around the upper end of the longitudinal tube. Liquid may be transferred from the lower reservoir to the upper reservoir by the application of pressure on the lower reservoir while the two slots are aligned. In a preferred embodiment, the container is rendered child-resistant through the provision of a cap.
Claims16
A container for dispensing liquids, said container comprising:
- a. a lower reservoir and an upper reservoir separated by a gasket, said gasket having an aperture therethrough and comprising an inner sleeve drain;
- b. a longitudinal tube extending through said gasket, said tube having a lower end extending into said lower reservoir, and an upper end extending into said upper reservoir, whereby when pressure is applied to said lower reservoir, liquid in said lower reservoir can travel through said tube and into said upper reservoir, said upper end of said tube having a longitudinal slot extending therethrough;
- c. a dispensing tip having a longitudinal sleeve extending therefrom, said longitudinal sleeve having a helical slit extending therethrough and comprising a base comprising an outer sleeve drain, said sleeve being disposed concentrically around said upper end of said tube such that it can rotate around said tube, whereby the maximum amount of liquid that can be maintained in said upper reservoir is controlled by the relative positions of said helical slit and said longitudinal slot and the relative positions of said inner sleeve drain and said outer sleeve drain.
A container for dispensing liquids, said container comprising:
- a. a lower reservoir and an upper reservoir in fluid communication with each other and separated by a gasket said gasket having an aperture therethrough and comprising an inner sleeve drain;
- b. a longitudinal tube extending through said gasket, said tube having a lower end extending into said lower reservoir, and an upper end extending into said upper reservoir, whereby when pressure is applied to said lower reservoir, liquid in said lower reservoir can travel through said tube and into said upper reservoir, said upper end of said tube having a slot extending therethrough;
- c. a dispensing tip having a longitudinal sleeve extending therefrom, said longitudinal sleeve having a slot extending therethrough, and comprising a base comprising an outer sleeve drain, said sleeve being disposed concentrically around said upper end of said tube such that said tube and sleeve can move relative to each other, whereby the maximum amount of liquid that can travel through said tube from said lower reservoir to said upper reservoir is controlled by changing the relative positions of said slots and the relative positions of said sleeve drains.
