ABSTRACT:
A bottle sealer includes a telescopic expansible hollow extension formed on an annular portion of the sealer sealed in a bottleneck, and fluidically communicated with a liquid filled in a bottle so that when the bottle filled with a liquid or water is subjected to a freezing temperature to become ice, the telescopic hollow extension may serve as a buffer for absorbing the volume expansion due to a conversion of water into ice.
