The present invention provides a watering and feeding dual-purpose vessel construction used as a vessel assembly for watering or feeding animals, the assembly comprising a top part served as a filling unit for adding water or forage, and a bottom part served as a bearing unit allowed for animals to drink water or peck up forage with beaks. A plurality of vertically spaced slots are depressedly provided at a predetermined height on the filling unit of top part at two corresponding sides, so as to cooperate with two protrusions, extendingly provided at an inner side and in the upper middle of the bearing unit of bottom part, and then to be inserted into them as desired. Due to the requirement for water filling/forage filling control of the vessel assembly, the filling unit of top part may be mounted on the bearing unit of bottom part by hand, in such a way that a predetermined and controlled water filling/forage filling amount between a discharging device screwed on the filling unit of top part and the bearing unit of bottom part may be achieved.本發明是提供一種飲飼兩用容器結構,是對作為動物飲水或餵食飼料的容器組體含括的上端作為添加入水或飼料的承裝單元、及作為供動物喙部飲水或啄取飼料的承置單元在作組合,是利用上端承裝單元位在預設高度的對應兩側凹設以上下間距的數道槽道,以配合下端承置單元偏上部位內側延伸的兩凸部依據所須切入,作為容器組體在須作入水/入料量的控制,能藉手部將上端承裝單元施以架設在下端承置單元,以達到旋鎖在上端承裝單元的出水裝置能與下端承置單元之間獲有預設的控制入水/或落料。1‧‧‧承裝單元13‧‧‧槽道131‧‧‧缺口141‧‧‧第一槽道142‧‧‧第二槽道15‧‧‧出水裝置2‧‧‧承置單元21‧‧‧透孔22‧‧‧凸部4‧‧‧容器組體
