PROBLEM TO BE SOLVED: To provide an air cleaning greening device which has satisfactory workability, can prevent density reduction of a planting base associated with planting or transplantation, or flowability reduction of air caused by uneven density, and can be light in weight, and to provide a cultivation container thereof.SOLUTION: The air cleaning greening device 1 comprises: a planting layer 2 a ventilation layer 3 positioned on a rear side of the planting layer 2 and blowing means 4 for sending air to the ventilation layer 3. The planting layer 2 has a plurality of cultivation containers 5 and a frame 6. The cultivation container 5 is in a cup shape whose mouth part is an opening 5a for planting, is filled with a planting base 7, and has an opening 5b for ventilation and water conduction at an area different from the opening 5a for planting. The frame 6 supports the plurality of cultivation containers 5 in an insertable/detachable manner while directing the opening 5a for planting toward the opposite side of the ventilation layer 3, and makes air having passed through the ventilation layer 3 ventilate through the opening 5b for ventilation and water conduction of the cultivation container 5 and seals the air to the outside.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】 施工性が良く、植栽や植え替えに伴う植栽基盤の密度低下や密度のむらによる空気の流動性低下を解消でき、装置の軽量化も可能な空気清浄緑化装置、およびその栽培容器を提供する。【解決手段】 この空気清浄緑化装置1は、植栽層2と、この植栽層2の裏側に位置する通気層3と、この通気層3に空気を送り込む送風手段4とを備える。植栽層2は、複数の栽培容器5とフレーム6とを有する。栽培容器5は、口部が植栽用開口部5aとなるカップ状とされて植栽基盤7が充填されかつ植栽用開口部5aとは別の箇所に通気・通水用開口部5bを有する。フレーム6は、前記複数の栽培容器5を、植栽用開口部5aを通気層3とは反対側に向けて挿脱可能に支持し、かつ通気層3を通過した空気を栽培容器5の通気・通水用開口部5bに通気可能でかつ外部に対して密封する。【選択図】 図1
