1 Claim. (Cl. 222-393)
This invention relates to improvements in liquid dis
pensing devices and, in particular, to a valve actuating
and flow channeling device for pressurized containers.
It is a particular object of the present invention to
provide a removable valve actuating and ?ow channel~
erally internally of the container a dispensing valve struc
ture 22.
The dispensing valve structure 22, in the illustrated
form of the invention, is of the type that is adapted to
dispense a metered quantity of material from the con
tainer each time the valve mechanism is opened.
The valve mechanism 22 includes a dip tube 24, the
lower end 26 of which terminates adjacent the bottom
16 of the container. The upper end 28 of the dip tube
24 discharges into a dispensing chamber 30. The dis
pensing chamber 30 is provided with a reciprocally
mounted valve member 32 which includes a stem por

In the illustrated form of the invention, the up
standing arm 72 is re-curved as at 74 to receive a formed

60 is rotated about the flow channeling member 50 in
either of the directions indicated by directional arrows A
