Appeal No. 2001-2126
Application 09/141,069
The sealing lip 2 departs from the holding part
1 in the region of the transition-between the limb 4
and the web 5. It is composed of essentially the
same material, but its hardness is adjusted to a
somewhat lower value. . . . The thermoplastic
material forming the holding part 1 and the sealing
lip 2 is co-extruded, by a known technique, the two
grades of material being securely welded to one
another in the transition region.
The sealing lip 2 contains a reinforcing insert
10, composed of spring steel wire, bent into a
zigzag shape, this wire being thinner than that of
the reinforcing insert 8. The strength of the
reinforcing
insert 10 and the thickness of thermoplastic
material surrounding it are chosen, by design, such
that the desired sealing force and compliance
results when the sealing lip is deformed by the
expected amount [column 4, lines 21 through 59].
Anticipation is established only when a single prior art
