dimensions of the first material exceed inner dimensions of a
space in the cartridge body so as to hold the material outward
against the cartridge body when inserted therein.
The applied prior art would have suggested the
limitations. Koitabashi teaches that the initial outer
dimensions of its vacuum producing material exceed inner
dimensions of a space in the ink container to hold the
material outward against the container when inserted therein.
Specifically, “[i]t is desirable that a foamed material ... is
cut-into a desired dimension, and it is squeezed into the
vacuum producing material container so as to provide the
desired pore density and the capillary force.” P. 10, ll. 10-

Because Koitabashi’s foamed material is squeezed into its
vacuum producing material container so as to provide the
desired pore density and the capillary force, we are persuaded
