Cartridges introduced
An innovation was the replaceable blade cartridge containing the blade which reduced the risk of the user receiving a cut from the unprotected blades used up until then.These took the form of a cartridge,with the blade fixed within a plastic enclosure of the type still in use today.In 1965 Gillette introduced the Techmatic razor which utilized a cartridge with a steel strip that could be wound forward to expose a fresh section of new blade.
我參考了第五版的 MACQUARIE DICTIONARY 里面的解釋有 a cylindrical case of pasteborad,metal,or the like,for holding a complete charge of powder,and often also the bullet,or a shot for a rifle,machine gun,or other small gun.(Macquarie Dictionary 5th ed,2009) 其他也都是case的意思 只不過(guò)不同的case.
