  • Patent number: 5119974
    Abstract: The present invention relates to a spray bottle having full circle, continuous operational capability. It includes a mouth and a bottom wall, a reservoir of contained liquid, a human-powered pump sprayer attached to the mouth of the container, a straw extending into the contained liquid and a full circle, continuous complementary operative feed system in operational contact with the pump sprayer through the straw. The feed system of the present invention alternately connects the contained liquid to first and second entry ports in parallel relative to the straw as a function of working position. Assuming that the container is full or nearly full of liquid and that the spray bottle is in a normal upright working position, a first valve associated with the entry port near the bottom wall, is made to be operative open to liquid flow. Similarly, a second valve associated with the second entry port near the mouth of the container, is operated in a closed condition.
