History of suitcase development
The suitcase was not invented until 199 1. The history of suitcase development is bound to be closely related to tourism history, transportation and industrial manufacturing level. Early human migration was mostly wrapped in coarse cloth. Later, with the development of carriages, trains, cars and cruise ships, coarse cloth parcels also experienced the evolution from wood, leather to iron.
However, until the middle and late19th century, the suitcase was still a bulky behemoth, which was very inconvenient to carry. By the end of19th century, the transformation of transportation promoted the great development of tourism, and luggage really began to develop.
1972, Bernard Sadow from America invented a hand luggage with four wheels and a belt, and obtained a patent. Since then, wheeled suitcases have gradually become popular.
