The invention relates to a medicament easily-mixing bottle. The medicament easily-mixing bottle comprises a bottle body, a bottleneck and an elastic press device. The bottle body and the bottleneck are connected detachably. The bottle body is divided into medicament cavities by a vertical partition plate. The bottoms of the medicament cavities are sealed by a sliding plate. The sliding plate can only be moved horizontally along the inner wall of the bottle body and the side wall of the partition plate. The tops of the medicament cavities are sealed by a one-way valve. The one-way valve only allows medicament to flow out of the medicament cavities. Vent holes corresponding to the medicament cavities one by one are formed in the bottom of the bottle body. A fixed shaft is installed on the axis of the bottleneck. A rotatable stirring wheel is arranged on the fixed shaft in a sleeving mode. A guiding-out pipe is arranged on the side wall of the elastic press device. The guiding-out pipe is provided with a one-way door which only allows the medicament to flow out. The medicament bottle is novel and unique in structure, medicines can quickly disposed, the progress of experiment is accelerated, and the disposed medicines are uniform and stable.
