comprised of a hard plug rod 11 and a hollow cylindrical elastic
stopper body 12. The plug rod 11 comprises a top handhold portion
111, a positioning flange 112 extended around the periphery of the
bottom side of the handhold portion 111, a through hole 113
transversely extended through the top handhold portion 11I, bottom
cone 115, and a tapered shank 114 connected between the top
handhold portion 111 and the bottom cone 115. The tapered shank
114 has a diameter gradually reduced in direction from the bottom
cone 115 toward the top handhold portion 111. The stopper body 12
has a tapered upper section 121 made gradually greater toward the
top, an axially extended center through hole 122 adapted to receive
the plug rod 11.
Referring to FIG. 3 and FIG. 1 again, when in use, the
stopper body 12 is inserted into the mouth 31 of a container 3, the
tapered upper section 121 is stopped above the mouth 31,
preventing the stopper body 12 from falling to the inside of the
container 3. Thereafter, the plug god 11 is inserted through the
axially extended center through hole 122 to expand the stopper
body 12 radially against the inner surface of the mouth 31 of the
container 3, sealing the container 3 tightly. When the plug rod 11
5
CA 02421301 2003-03-07
inserted into the axially extended center through hole 122 to
expand the stopper body 12 radially outwards, the stopper body 12
is stopped against the inner surface of the mouth 31 and closely
pressed on the periphery of the tapered shank 114 and the periphery
of the bottom cone 115, preventing a leakage. When removing the
container stopper 1 from the container 3, hold the tapered upper
section 121 with one hand and then press the plug rod 11 with the
other hand to force the positioning flange 112 into the inside of the
axially extended center through hole 122, at this time the diameter
of the lower part of the stopper body 12 is relatively reduced and
disengaged from the inner surface of the mouth 31, and therefore
the container stopper 1 can easily be pulled out of the mouth 31 of
the container 3.
Referring to FIGS. 4 and 5 and FIG. 3 again, the container
stopper 1 can be used to seal a container of any of a variety of
shapes. Further, a cord member 4 or chain 4' may be fastened to the
through hole 113.
