Der Yaw Mould Company, Ltd. Was founded by Mr. Yang

Heng-Te and Mr. Wu Lien Sheng in 1975. They expanded

into the housewares market and in 1978 they formed Ku

Yu Plastic Ent. Co. The company took a major step into

the Cork Ejector market with Yang Heng Te’s April 11,

2003 Patent 528,056. Here’s the patent abstract:

A cork removal apparatus in the invention has an

exterior barrel, a interior barrel mounted inside the

exterior barrel, a telescoping barrel engaged between the

exterior barrel and the interior barrel, a needle, a

partition plate attached inside the telescoping barrel and

extended though by the needle, and a cover with a press-

in member. The needle fixed at a bottom of the interior

barrel has a gas inlet, a gas passageway and a gas outlet. Place a gas container into the interior barrel

with its release nozzle downwardly aligned to the gas inlet, combine the cover on the exterior barrel

and penetrate the needle through a cork so that a depressing of the press-in member can force gas

of the gas container to flow through the needle into the bottle to extract the cork upwardly from

the bottle to achieve a rapid, convenient, laborsaving and safe removal of a cork.

This cork ejector is marketed by Sharper Image and the Wine Enthusiast as the "Wine Genie." The

packaging indicates the product is made in Taiwan and the United States contact is Lentek

International, Kissimmee, Florida. It has a foil cutter stand that snaps on the base.
