The spreader has a housing for receiving a first receptacle and a second
receptacle. The first receptacle is a cartridge of fluid, such as paint.
The second receptacle is a manifold having a secondary reservoir, a
meter, and a spreading material. Paint is transferred from the first
receptacle to the second receptacle via a main conduit, with a pair of
pistons acting upon the main conduit between a pair of one directional
check valves. The pair of pistons may be replaced by a button pump having
two one way valves. The manifold is slideably engaged to the housing such
that manifolds having different conduit arrangements, larger conduits,
different meters, different spreading materials, and different end
portions, may be used.
