发明名称 Cork extractor
摘要 The invention pertains to an apparatus for extracting a cork from a bottle comprising a cork-engaging member, including a corkscrew, and a holder for aligning and guiding the corkscrew, via its own diameter, with respect to the bottle. The corkscrew itself is improved by the provision of an outer layer of friction reducing material such as a tetrafluoroethylene or other suitable plastic. Additionally, the tip portion of the corkscrew is formed in an improved manner which prevents fragments of cork from breaking off and falling into the bottle even though the screw is driven completely through the cork. Also disclosed is an improved method of making such a corkscrew.
