ABSTRACT:
The present inventon is a liquid metered dispensing container of the squeezable type. The squeezable container has an opening for dispensing liquid therefrom at one end and a bottom at the other end. A non-flexible trap chamber is connected to the opening and extends outwardly therefrom. The trap chamber has a lower end inserted into the container opening and has an inlet orifice extending from the lower end into the container. The inlet orifice is adapted to receive a dip tube which is attached thereto and extends close to or at the bottom of the container. The trap chamber has an upper end with a dispensing orifice. This is small enough to prevent dripping of liquid therefrom by gravity when the bottle is inverted but is large enough to dispense liquid therefrom when the bottle itself is squeezed. A one way valve is connected to the lower end of the trap chamber which permits liquid to flow from the container to the trap chamber but not vice versa. The trap chamber may have indicia so that exact dosage levels of different amounts may be squeezed into the chamber, or the chamber itself may have a single, predetermined volume.
