PROBLEM TO BE SOLVED: To provide a package with an opening piece that can allow one to open a cylindrical film easily and well.SOLUTION: A package 1 with an opening piece includes a cylindrical film 5 made from a synthetic resin film formed in a cylindrical shape, a content 9 filling the cylindrical film 5, ligation members 6 forming ligation end parts 5E and 5F by ligating both end parts where the cylindrical film 5 filled with the content 9 is collected with each other, and an opening piece 10 made from a synthetic resin film which is adhered to the cylindrical film 5. The adhesion between the cylindrical film 5 and the opening piece 10 is performed including a single adhesion line 11 extending in an orthogonal direction with respect to the longitudinal direction of the cylindrical film 5. The adhesion line 11 is formed over a distance Lc that is 0.6 times or more and 1.5 times or less of a diameter Ld, away from a root part of a ligation member 6E along the surface of the cylindrical film 5 in the axial direction of the cylindrical film 5. The length of the opening piece 10 is that of the adhesion line 11 or more and less than the diameter Ld.COPYRIGHT: (C)2011,JPO&INPIT【課題】筒状フィルムの開封を容易かつきれいに行うことができる開封片付き包装体を提供すること。【解決手段】開封片付き包装体1は、合成樹脂のフィルムが筒状に形成された筒状フィルム5と、筒状フィルム5に充填された内容物9と、内容物9が充填された筒状フィルム5の集束された両端部を結紮して結紮端部5E、5Fを形成する結紮部材6と、筒状フィルム5に溶着された合成樹脂のフィルムの開封片10とを備える。筒状フィルム5と開封片10との溶着は、筒状フィルム5の長手方向に対して直交する方向に延びる一本溶着線11を含んで行われている。一本溶着線11は、結紮部材6Eの根元から、筒状フィルム5の軸方向に筒状フィルム5の表面に沿って、直径Ldの0.6倍以上1.5倍以下の距離Lcに形成されている。開封片10は、一本溶着線11の長さ以上、直径Ldの長さ未満の長さを有する。【選択図】図1
