successful to find a manufacturer and salesman in Taiwan and China. No serious

The patent is primarily
concerned with the air
pump rather than the
accessories. Nowhere
in the patent does
Wen-San Jou call a cork
a cork. Cork removal is
shown in the last of five
drawings and this
description is given:
"FIG. 5 shows an
operational use of the
portable air pump
when filling bottle 6. In
such applications, bottle
6 may include a plug 60 [he's referring to the cork] which can be ejectively removed
from bottle 6 due to inner pressure of bottle 6 being continuously increased if a pointed
of air nozzle 4 is passed therethrough and air is continuously inserted into bottle 6"
[sic].
A notation on the box cautions: "This is not a general toy but a useful appliance. Be sure
to keep out of reach of children."
