PROBLEM TO BE SOLVED: To provide a cut cake packaging bag which is suitable especially for packaging cut cakes.SOLUTION: The cut cake packaging bag 10 which includes a bottom face section 1 of an approximate isosceles triangle shape consisting of two long sides L and one short side S, and has a configuration which is suitable for packaging cut cakes having an approximate wedge shape, includes a section 2 to be tucked in which is not less than 20% and less than 50% of the internal dimensional width (a length between A and F shown in Fig.1) of the packaging bag under a folded state, only on the short side. Then, the apex angle θ of a heat-seal H or a weld-cut seal of a mountain shape formed on the bottom end of the packaging bag under the folded state is set to be 120 to 130°. Thus, the cut cake packaging bag 10 provides a housing space of an approximate isosceles triangle prism shape when the folded packaging bag 10 is spread out to be stereoscopic.COPYRIGHT: (C)2013,JPO&INPIT【課題】 特にカットケーキを包装するのに適したカットケーキ包装用袋を提供すること。【解決手段】2つの長辺Lと、1つの短辺Sとからなる略二等辺三角形状の底面部1を備え、略楔形のカットケーキを包装するのに適した形態を有するカットケーキ包装用袋10であって、折り畳まれた状態の包装用袋の内寸幅の20%以上~50%未満の折込部2を前記短辺側にのみ備え、折り畳まれた状態の包装用袋の底端部に形成される山形のヒートシールH又は溶断シールの頂角θを120~130度とすることで、略二等辺三角柱形状の収納空間を展開時に備えることを特徴とするカットケーキ包装用袋10である。【選択図】図1
