closure is in screw-threaded engagement with the vessel. A
housing face wall and housing side wall at the internal rim
abruptly merge into each other, i.e., the radius of curvature
of the internal rim approximates zero in a longitudinal cross-
section.
In our opinion, it would have been obvious to one having
ordinary skill in the art, from a combined consideration of

From our perspective, the incentive on the part of one having

boiling by Jessop as reasonably suggestive thereof. In the
