Appeal 2006-1127
Application 10/712,970
Independent claim 1 is representative of the subject matter on appeal
and is set forth below:
1. A spraying device comprising:
a cartridge containing a first liquid, the cartridge being removably
connected to a sprayer body, the cartridge being oriented such that gravity
exerts a downward force on the first liquid;
the sprayer body comprising:
a conduit for receiving a second liquid;
a movable valve structure having first and second liquid passageways,
the first passageway communicating with the first liquid from the cartridge
and the second passageway communicating with the second liquid flowing
from the conduit;
a manual actuator positioned in operative relationship with the
movable valve structure enabling movement of the valve structure between
at least three discrete positions including:
a) a first position enabling the second liquid to flow through the valve
structure to create a reduced pressure in the valve structure which draws the
first liquid out of the cartridge and into the valve structure whereby the first
and the second liquids mix to form an outlet stream which flows through the
valve structure;
b) a second position enabling the second liquid only to flow through
the valve structure and blocking the flow of the first liquid through the valve
structure, and
c) a third position blocking the first and the second liquids from
flowing through the valve structure; and
