Appeal No. 2001-0109
Application 08/871,898
The apparatus includes a plastic ring (32) having an
inward-facing surface (34) complementary to the outward-facing
surface (26) of the plug (23). See Appellant’s specification
Figures 1 and 4, see also page 4, lines 21-28 and page 5, lines
22-33. The dimensions of the ring (32), in relation to the
dimensions of the plug (23) and of the lip stretched over the
outer surface (26) of the plug (23) cause a tight interference
fit. See Appellant’s specification Figures 1 and 4, see also
page 4, lines 21-28, page 6, lines 16-22, page 6, line 34
through page 7, line 15, and Appellant’s Amendment B, Paper
No.6, dated June 28, 1999, page 3, paragraphs 2-3. The ring
(32) acts to seal and grip the lip, tightly and securely
between the plug (23) by a uniform interference fit. See
Appellant’s specification Figures 1 and 4, see also page 4,
lines 21-28, page 6, lines 16-22, page 6, line 34 through page
7, line 15, and Appellant’s Amendment B, Paper No.6, dated June
28, 1999, page 3, paragraphs 2-3.
