The recovery rate of glass bottle reach over 60% every year, however, the recovery rate of bottle cap never be paid attention to. Our design is to attach importance to the recovery of the glass bottle cap in poverty areas. Differ from ordinary bottle cap, letter cap has its own letter inside the bottle cap. Children in poverty areas who have no books or pens can spell words by the letter cap after drinking the beverage bottles. Teachers in school also can use the letter cap to teach children recognize letter and spell words which reuse the bottle cap and reduce the pollution of bottle waste.
