PROBLEM TO BE SOLVED: To place various decorations to be placed on a round rice-cake vessel without generating positional deviation on the round rice-cake vessel and to stably and reliably fix the decorations even when sizes, heights and the like of the decorations are different from each other.SOLUTION: In a fixing cover tool supporting decorations D placed on the round rice-cake vessel P filled with a rice cake and having an outer shape of a superposed rice cake, a fixing body 2 covering the round rice-cake vessel P to be fixed to the round rice-cake vessel P and a supporting body 5 supporting the decorations D placed on the round rice-cake vessel P are integrally formed to form a cover tool body 1. The supporting body 5 of the cover tool body 1 forms a supporting part 6 which is formed to be expanded in a cylindrical shape toward an upper part in a top part of the fixing body 2 and supports the decorations D and whose upper part is released. In the supporting part 6, the appropriate number of pressing pieces 7 are disposed in the top part of the supporting body 5, wherein the pressing pieces 7 are inclined from a peripheral edge of the top part toward the lower side on a center side of the supporting body 5 and whose edges come into press contact with the decorations D.COPYRIGHT: (C)2013,JPO&INPIT【課題】鏡餅容器上に載置する各種の飾り物を鏡餅容器上に位置ずれを生じさせずに載置でき、その飾り物の大小、高低等が異なっていて安定して確実に固定できる。【解決手段】餅を充填して重ね餅状の外形を呈する鏡餅容器P上に載置する飾り物Dを支持する固定カバー具であって、鏡餅容器Pを覆って鏡餅容器Pに固定させる固定体2と、鏡餅容器P上に載置する飾り物Dを支持する支持体5とを一体にしたカバー具本体1を形成する。このカバー具本体1の支持体5は、固定体2の頂部に上方に向かって筒状に膨出形成してあって、飾り物Dを支持する上部開放の支持部6を形成する。支持部6は、支持体5の頂部に、この頂部の周縁から支持体5の中心側下方に向かって傾斜し、端縁が飾り物Dを押圧当接している適数の押圧片7を配設してある。【選択図】図1
