< Topic >The freshness retention tube of the flower containment the water content which can absorb the flower is offered.SolutionsThe freshness retention tube of the flower to include computer 1, the said computer storage of water section to provide 11 and soft deformation possible interposition installation section 111, to provide the water chamber 13 which at the same time communicates the storage of water section and the interposition installation section to this internal, the interposition installation section to provide the interposition hole which is communicated with the water chamber, the said storage of water section to provide soft step 112, when because of this, interposing the flower in the interposition hole 121, the interposition installation section the inside concave deformation do according to the interposition installation direction of the flower, adjust to deformation, the interposition hole containment the close state of 121 and the flower. Because of this when the flower absorbs the moisture inside the water chamber, the moisture inside the water chamber decreases, makes soft step deform 112, selects the moisture, makes the flower absorb, offers the effect of the efficient offering/accompanying water supply retention for the flower.< Choice figure >Drawing 4【課題】花が吸収できる水量を保持できる花の鮮度保存管を提供する。【解決手段】花の鮮度保存管は、本体1を含み、該本体は、貯水部11及び軟質の変形可能な挿入設置部111を設け、且つ本体内に貯水部及び挿入設置部を連通する蓄水室13を設け、挿入設置部は、蓄水室と連通する挿入孔を設け、該貯水部は、軟質段112を設け、これにより、花を挿入孔121に挿入する時、挿入設置部が花の挿入設置方向に沿って内凹変形し、変形に合わせ、挿入孔121及び花の密接状態を保持する。これにより花が蓄水室内の水分を吸収する時、蓄水室内の水分が減少し、軟質段112を変形させ、水分を抽出し、花に吸収させ、花に対する効率的な供給水保存の効果を提供する。【選択図】図4
