PROBLEM TO BE SOLVED: To provide a corolla forming tool in which three-dimensional assembling of the corolla of a flower into a desired configuration while protecting the corolla, and planar development for easy transportation and storage without bulkiness can be performed easily, quickly and repeatedly anywhere.SOLUTION: A corolla forming tool 10 of the present invention comprises a peripheral wall part 2 formed in a recessed cone shape an opening part 3 into which a flower axis of the flower may be inserted at least 2 or more curved parts 4 formed by making curve on the peripheral wall part. In addition, the corolla forming tool 10 also comprises reversible curving means 5 which maintains the curved state of the curved parts and releases it. The corolla forming tool may make a curve on a flexible sheet having an opening part arranged approximately on the center so as to form the recessed cone shape. The curve on the sheet is made along with a straight line connecting a point of the side of a top edge part 21 and a point of the side of a base bottom part 22 on the peripheral wall part. In addition, when the flower axis of the flower is inserted into the opening part of the corolla forming tool, an outside edge of the corolla is surrounded and protected with the peripheral wall part so as to be formed into a desired configuration (a heart shape).COPYRIGHT: (C)2015,JPO&INPIT【課題】花卉の花冠を保護しつつ所望形状に成形するための立体的な組立てと、嵩張らずに搬送や収納をし易くするための平面的な展開が、どこでも容易に素早く繰り返し行うことができる花冠成形具を提供する。【解決手段】本発明の花冠成形具10は、凹錐状に形成した周壁部2と、花卉の花軸を挿通可能とする開放部3と、該周壁部を曲折して設けた少なくとも2以上の屈曲部4とを有する。また、該屈曲部の曲折状態の維持及びその解除を可能とする可逆的曲折手段5を備える。花冠成形具は、略中心に開放部を設けた可撓性を有するシート体を曲折することで凹錐状に形成できる。シート体の曲折は、周壁部の頂縁部21側の一点と基底部22側の一点とを結ぶ直線に沿って行う。そして、花冠成形具の開放部に花卉の花軸を挿通すると、花冠の外側は周壁部に取り囲まれて保護されつつ所望形状(ハート形)に成形されるものとなる。【選択図】図1
