The present invention relates to a diaper structure and its method. The structure comprises a main body and a gathering container jointed to one side of the main body. A guiding part is formed on one side of the main body, and the gathering container and the guiding part are oppositely matched with each other. One side of the gathering container is provided with an injection part and an exhaustion part for allowing external fluid to flow into the gathering container and exhausting fluid out of the gathering container. The method of cleaning the diaper includes (a) opening the injection part and the exhaustion part of the gathering container (b) guiding fluid from the injection part into the gathering container for performing a cleaning operation, and exhausting fluid out of the gathering container through the exhausting part and (c) closing the injection part and the exhaustion part. As a result, the diaper of the present invention can be repeatedly used, so as to achieve the advantage and function of re-using.本發明為有關一種尿布結構,其結構包含一主體及一結合於主體一側處之收集容器,收集容器為具有口部之袋體,主體於一側處形成一為開口之導引部,而收集容器與導引部對接配合,且收集容器之一側處具有一供外部流體進入收集容器內、及排出收集容器外之為塞口的注入部及排出部;使用時將結合於主體側處的收集容器上之注入部及排出部開啟,並垂放收集容器使注入部之位置高於排出部,然後由注入部導入外部流體並進入收集容器內進行清潔,並由排出部將流體排出收集容器外,再將注入部及排出部封閉,藉此本發明之尿布將可反覆的進行使用,達到重覆使用之優點功效。1‧‧‧主體11‧‧‧導引部12‧‧‧彈性固定帶13‧‧‧黏性結合組件2‧‧‧收集容器21‧‧‧注入部22‧‧‧排出部
