PROBLEM TO BE SOLVED: To provide a planting container preventing freeze or high-temperature drying of soil by performing heat insulation or heat radiation such that cold heat coming from a side face of the planting container or high-temperature heat by the irradiation of sunlight is not transferred to the planting soil inside the planting container.SOLUTION: A planting container includes: an inner wall provided between an outer wall and a soil space of the planting container a gap serving as a movement passage allowing the vertically movement of air, provided between the outer wall and an inner wall a communication port communicating outside air and the gap, provided at the lower end of the outer wall and opening parts opening to the outside air, provided at the upper end of the gap. This configuration allows air to move upward or downward by cooling air or a temperature rise by high-temperature heat, and prevents transmission of the cold heat or high-temperature heat to soil by discharging it to the outside air.COPYRIGHT: (C)2014,JPO&INPIT【課題】本発明の課題は、植栽容器の側面からくる冷熱或いは太陽光の照射による高温熱を植栽容器内の植栽用土に伝わらないように保温或いは放熱を行い、用土の凍結や高温乾燥を防止可能とした植栽容器を提供することである。【解決手段】本発明の植栽容器は、植栽容器の外壁と用土空間の間に内壁、外壁と内壁の間に上下方向に空気を移動可能にする移動通路をなす空隙、外壁の下端に外気と空隙を連通する連通口、空隙の上端に外気に開いた開口部を備えたことで、空気の冷却または高温熱による昇温により空気を上方向または下方向に移動して冷熱または高温熱を外気に排出して用土への伝達を防止する。【選択図】図1
