A Novel Corkscrew Invention.
A corkscrew which will perform its function of extraction without spoiling the cork or making a hole in it is a novelty which should make a wide appeal. There is firstly to be considered the saving of corks—an important matter these days—and, in addition to this, it is claimed that the patent “Stap Corkscrew” illustrated avoids all unnecessary shaking of the bottle—a point which is of considerable importance in dealing with certain wines. In use the metal strips are pushed down gently with a rocking movement between the cork and the bottle neck. The cork is then extracted by pulling up gently and at the same time turning the screw. The appliance is light in weight and can be easily packed. The invention is handled in this country by Messrs Leverlite Lamps, 23A Old Bond Street, London, W.I.
