科技资讯:谁发明了法式压滤咖啡壶?  

"From the beginning
the French devoted more attention than any other people to coffee brewing
" William Harrison Ukers wrote in "All About Coffee
" published in 1922. The first French coffee maker appeared around 1800
Ukers claimed
and the first one made of glass followed 40 years later. Though Ukers's encyclopedic work defined dozens of devices
it never mentioned the simple plunger-style vessel that we've e to call the "French press."
That coffee maker — known as the cafetière in Britain — wasn't popular until after Ukers's death
but the technology was around long before he wrote his book. In March 1852
a Paris metalsmith and a merchant received a joint patent for "the filtering of coffee by means of a piston." The patent described a rod attached to a piece of tin pierced with holes and sandwiched beeen o layers of flannel. The rod would be pressed by hand into a cylindrical vessel. "By lowering the piston
" the inventors wrote
"filtered coffee is obtained above it
perfectly clear."
But the French press did not bee well known until the late 1920s
when a Milanese firm patented a version of the French invention. The pany perfected the device in the years that followed: A version introduced in 1935 had a spring that wrapped around the plunger discs to hold them flush with the cylinder.
但是法式压滤壶直到20世纪20年代才为世人所知，当时一个米兰工厂为这项法国发明的一个版本申请专利。其后这家公司又改良了这种设备。1935年推出的一个型号有一个弹簧包裹在泵盘周围，让泵盘可以水平地压入圆柱容器。
A similar design spread through Europe in the 1950s. But it took a while for the gadget to make its way to the United States
and still longer for it to gain its current appellation. (Even now
the Oxford English Dictionary defines the French press first and foremost as an exercise designed to "develop and strengthen the biceps.") As of the early 1980s
some Americans followed British usage and called it a cafetière; others used the phrase "French plunger-type." In 1993
Florence Fabricant explained the "French-press method" to readers of The New York Times as a favorite of connoisseurs. The method had one major drawback
she noted: "The coffee is sometimes muddy."
