A spork is a hybrid form of cutlery taking the form of a spoon-like shallow scoop with two to four fork tines. Spork-like utensils, such as the terrapin fork or ice cream fork, have been manufactured since the late 19th century;〔(【引用サイトリンク】Terrapin Forks (1890 - 1900) )〕 patents for spork-like designs date back to at least 1874, and the word "spork" was registered as a trademark in the US and the UK decades later. They are used by fast food restaurants, schools, prisons, the military, backpackers and in airline meals. The word ''spork'' combines ''spoon'' and ''fork''. Similarly, the word ''foon'' is a blend of ''fork'' and ''spoon''. The word ''"spork"'' appeared in the 1909 supplement to the ''Century Dictionary'', where it was described as a trade name and "a 'portmanteau-word' applied to a long, slender spoon having, at the end of the bowl, projections resembling the tines of a fork". ==History== In the US, patents for sporks and proto-sporks have been issued. A combined spoon, fork, and knife closely resembling the modern spork was invented by Samuel W. Francis and issued US Patent 147,119 in February 1874. Other early patents predating the modern spork include US Patent 904,553, for a "cutting spoon", granted on November 24, 1908 to Harry L. McCoy and US Patent 1,044,869, for a spoon with a tined edge, granted to Frank Emmenegger in November 1912. Many of these inventions predated the use of the term "spork". Given this significant prior art, the basic concept of combining aspects of a spoon and fork is well established; more modern patents have limited themselves to the specific implementation and appearance of the spork. These design patents do not prevent anyone from designing and manufacturing a different version of a spork. Examples of modern US design patents for sporks include patent number D247,153 issued in February 1978 and patent D388,664 issued in January 1998. The ''word'' spork originated in the early 20th century to describe such devices. In 1951, Hyde W. Ballard of Westtown, Pennsylvania filed an application with the United States Patent Office (USPO; now the United States Patent and Trademark Office) to register "Spork" as a trademark for a combination spoon and fork made of stainless steel.〔U.S. trademark application, serial no. 609,277, filed January 26, 1951. Official Gazette of the United States Patent Office, (vol. 665 ), no. 3, p. 673, December 16, 1952. Accessed April 2, 2014.〕 The Van Brode Milling Company subsequently registered SPORK for a combination plastic spoon, fork and knife at the USPO on October 27, 1970, but the registration expired 20 years later.〔U.S. trademark registration no. (901,492 ), filed October 24, 1969, registered October 27, 1970. Accessed April 2, 2014.〕 The word Spork accompanied by a stylised design is registered in the U.S. in relation to hand tools, in the name of a UK-based individual.〔U.S. trademark registration no. (2,514,381 ), filed March 23, 2000, registered December 4, 2001. Accessed April 2, 2014.〕 In the UK, Plastico Limited registered Spork as a trademark in relation to cutlery with effect from September 18, 1975 (reg. no. 1052291). The registration is now in the name of another company and remains in force. The trademark is also registered in the UK in relation to gardening tools in the name of the same UK based individual who owns US trademark registration no. 2514381. Another British company, Lifeventure, sells titanium and plastic versions using the name "Forkspoon". In an unsuccessful lawsuit in 1999 where the company Regalzone sought to invalidate Plastico Limited's UK registration for Spork, Justice Neuberger wrote: 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「spork」の詳細全文を読む スポンサード リンク
