裝著。該米飯加工食品用包裝材1’係具備有：外薄膜10’ ;和與該外薄膜10’互助來形成袋部150’之內薄膜20’。 外薄膜1 〇 ’係以在平面視角呈長方形狀之一片薄膜所 構成。箱對於此，內薄膜20’係以一對薄膜20a’、20b’所 構成。一對薄膜20a’、20b’係在重疊於外薄膜10’之狀態 • 下，在與外薄膜1〇’的長方向正交的方向（以下稱爲寬度 方向）橫排地配置著。再者，在以下的說明，對於構成內 薄膜20’之一對薄膜20a、20b’中，將配置於外薄膜10’的 ^ 寬度方向的一端側之一方的薄膜20 a’稱爲第一內薄膜，而 配置於外薄膜10’的寬度方向的另一端側之另一方的薄膜 20b’稱爲第二內薄膜。 第一薄膜20a’及第二薄膜20b’分別形成爲較將外薄膜 10’於寬度方向分割成2等分者若干寬廣之長方形狀。又 ，第一薄膜20a’及第二薄膜20b’係配置成在外薄膜1〇’的 201033094 中央部，寬度方向的端部彼此以非接著的方式重疊，該重 疊之部分以外的外周端部係熱接著（密封）於外薄膜10’ 的外周端部。藉此，米飯加工食品用包裝材1’係以外薄膜 10’與內薄膜20’形成用來收納薄片狀食品SF’之袋部150’ 〇 又，這種的米飯加工食品用包裝材1係具備有開封手 段。開封手段具有各種形態者，一般係利用以延伸於與寬 度方向正交的方向（以下稱爲縱方向）延伸的方式黏接於 II 外薄膜10’的內面側之裁製帶（cut tape ) 101’、和由夾持 裁製帶ιοί’的方式設置於外薄膜ίο’的縱方向的兩端部的 - 缺口所組成的切口 102’、102’所構成。 — 爲了以上述結構的米飯加工食品用包裝材1’來包裝米 飯加工食品RF’，首先，在將薄片狀食品SF’收容於袋部 150’內後，將米飯加工食品載乘於內薄膜20’上，在該狀 態下，如圖24所示，以外薄膜10’被覆米飯加工食品RF’ 全體並予以包裝。接著，米飯加工食品用包裝材1’被黏接 ❹ 標籤等的封條30’，保持該預定的被覆狀態，包裝作業結 束。 又，爲了將包裝了米飯加工食品RF’之米飯加工食品 用包裝材1’開封，首先，藉由將裁製帶101’的一端部朝另 一端側拉引，來將外薄膜10’切斷於縱方向而在寬度方向 分割成2份。如此，外薄膜10’被分割成2份之米飯加工 食品用包裝材1’，然後，藉由將外薄膜10’朝寬度方向 拉引，藉此，外薄膜10’的寬度方向的一端側之一半與第 -6- 201033094 一薄膜20 a’受到熱接著部Hsl’（參照圖22及圖23)所成 爲一體者、和外薄膜10,的寬度方向的另一端側之一半與 第二薄膜20b’受到熱接著部Hs2,（參照圖22及圖23)所 成爲一體者，各別單側地被取走。於是，薄片狀食品SF’ 所捲繞之米飯加工食品RF’露出，能夠能夠一同食用這些 食品之狀態。 Φ 【發明內容】 [發明所欲解決之課題] 然而，上述結構的米飯加工食品用包裝材1’，會有無 法圓滑地開封之情況產生。 具體而言，上述結構的米飯加工食品用包裝材Γ，當 包裝米飯加工食品RF’時，會形成米飯加工食品用包裝材 1’的縱方向的一方的端部的兩角部4’、5’彼此深深地重疊 之重叠部G。 • 因此，在拉引了裁製帶101’之際，重疊部G會妨礙 該裁製帶101’的行進，會有該裁製帶101’在中途斷裂之情 況產生。因此，在這樣的情況，變得無法整齊地分割外薄 膜10’，反而會造成花費時間在開封作業上之問題點存在 因此，本發明係用來解決上述問題點而開發完成之發 明，其目的在於提供容易且確實地進行利用開封手段之切 斷，又可簡單地分割並開封之米飯加工食品用包裝材。 201033094 [用以解決課題之手段] 本發明之米飯加工食品用包裝材，係具備有··可分割 於寬度方向地形成之外薄膜；及經由薄片狀食品重疊於前 述外薄膜，並可分離於與外薄膜相同方向地形成之內薄膜 ，外薄膜及內薄膜的外周端部彼此被密封成包圍前述薄片 狀食品，將前述內薄膜作成爲內側來包裝米飯加工食品之 ^ 米飯加工食品用包裝材，其特徵爲：具備有爲了將前述外 薄膜分割於寬度方向而可將該外薄膜切斷於與寬度方向正 © 交的方向之開封手段，前述外薄膜及內薄膜係形成爲在平 面視角呈四角形狀，並且在寬度方向相鄰的二角部分或四 · 角部分形成有缺口部。 ‘ 若依據上述結構的米飯加工食品用包裝材，在將內薄 膜作成爲內側並將米飯加工食品與薄片狀食品一同包裝之 狀態下，藉由開封手段將外薄膜朝與寬度方向正交的縱方 ; 向切斷而呈2份地分割於寬度方向後，藉由朝米飯加工食 品用包裝材朝寬度方向拉引，將內薄膜及外薄膜的寬度方 Θ 向的各一半被一體地拆除。 又，上述結構的米飯加工食品用包裝材係可容易且確 實地進行上述這樣的開封。即，藉由在外薄膜及內薄膜的 在寬度方向相鄰的二角部分或四角部分設置缺口部，使得 米飯加工食品用包裝材，不會具有角部，因此，可將在包 裝了內容物之時間點的米飯加工食品用包裝材的重疊部縮 成非常小。即，上述結構的米飯加工食品用包裝材，由於 在包裝狀態下角部彼此的重疊會消失，故，實質上可將重 -8- 201033094 疊部的面積縮小。因此，在以開封手段切斷外薄膜之際， 成爲切斷阻礙者幾乎消失，能夠圓滑地開封。 又，藉由在米飯加工食品用包裝材（外薄膜及內薄膜 )的寬度方向相鄰的二角部分或四角部分設置缺口部，使 得從縱方向之任何方向均可進行包裝，因此亦可謀求作業 效率提昇。又，在將缺口部設置於密封外薄膜與內薄膜的 部分（接著部）內之情況時，能夠確保密封性，故，能夠 Φ 良好地維持袋部內的密封狀態，薄片狀食品不會因外部的 濕氣而受潮，極爲理想。 前述外薄膜及內薄膜，可設置從劃定前述缺口部之端 緣朝內側延伸之複數個切痕。藉此，能夠減少當進行開封 時作用於開封手.段之阻抗，使得開封作業變得容易。 前述開封手段亦可具備有以延伸於前述縱方向的方式 設置於外薄膜之至少2條的裁製帶，該至少2條的裁製帶 係設置成在前述縱方向的至少一部位相互地交叉。藉此， • 由於至少2條的裁製帶，係設置成從相互地交叉位置逐漸 地分離，故，當進行開封時，可形成較裁製帶本身的寬度 更廣的開口部，容易且可瞬間地取出米飯加工食品。 [發明效果] 如以上所述，若依據本發明，可達到下述優良效果， 即，能夠容易且確實地進行利用開封手段之切斷，並可簡 單地分割並開封。 201033094 【實施方式】 以下，參照圖面，說明關於本發明的第一實施形態之 米飯加工食品用包裝材。 圖1至圖3係顯示本實施形態之米飯加工食品用包裝 材。圖1係顯示米飯加工食品用包裝材的內裝側之槪略裏 ^ 面圖，圖2係顯示圖1所示的米飯加工食品用包裝材的外 ’ 裝側之槪略表面圖，圖3係圖1之A-A線斷面圖。 本實施形態之米飯加工食品用包裝材1係如圖1至圖 參 3所示，具備有可分割於寬度方向地形成之外薄膜1〇、和 隔著海苔等的薄片狀食品SF重疊於前述外薄膜10，且可 朝與外薄膜10相同方向分離地形成之內薄膜20，外薄膜 1〇及內薄膜20的外周端部彼此熱接著（熱封）成包圍薄 片狀食品S F。 外薄膜10係設置成可被覆米飯加工食品RF之大小。 本實施形態之外薄膜10係在平面視角，形成爲縱長的四 角形狀（長方形狀）。 @ 外薄膜1〇係以具有熱接著性之泛用性薄膜所構成。 在此，作爲泛用性薄膜，可舉出例如聚乙烯、聚丙烯等的 合成樹脂薄膜。又，合成樹脂薄膜，存在有單軸延伸合成 樹脂薄膜、雙軸延伸合成樹脂薄膜、無延伸合成樹脂薄膜 ，故，可因應用途，選擇具適宜的特性之薄膜。 在此，單軸延伸合成樹脂薄膜係指具有可朝一方向延 伸的特性之薄膜，爲具有對延伸方向容易拉裂，但對與其 正交的方向不易拉裂的特性之薄膜，而雙軸延伸合成樹脂 -10- 201033094 薄膜係指具有可延伸於正交的二方向之特性的薄膜，爲具 有對兩方向容易拉裂之特性者。 在前述外薄膜ίο，設有開封手段1〇〇。本實施形態之 開封手段係以裁製帶101與切口 102所構成。裁製帶 ιοί係配置成在與外薄膜ίο的長方向（縱方向）正交的方 向（寬度方向）的中央部延伸於縱方向，從外薄膜10的 縱方向的一端到達另一端。又，裁製帶101係接著於外薄 • 膜10的其中任一方的面即可，在本實施形態，被接著於 外薄膜10的內面（與內薄膜20相對向的面）。再者，裁 製帶101係使用不容易被切斷程度之具有一定的強度者。 前述切口 102係在裁製帶1〇1所位在之外薄膜10的 部位中的縱方向的兩端部，在夾持著裁製帶101之狀態下 ，成對地設置著。再者，切口 102、102不限於設置於外 薄膜10的縱方向的兩端部者，亦可僅設置於其中任一方 的端部。即，切口 102、102係設置於至少成爲開封始端 • 側之端部即可。 又，藉由前述切口 102、102的存在，在外薄膜1〇的 _ 縱方向的端部，形成有摘取部103，其與裁製帶1〇1的端 部相對應。前述切口 102、102係成爲外薄膜10的切斷之 契機，同時導引開封初期的切斷方向。因此，當摘取藉由 切口 102、102所形成之摘取部103，並朝縱方向的另—端 側拉引時，裁製帶1 01對外薄膜1 〇之初期的行進變得容 易，因此可圓滑地進行外薄膜10的切斷。由於裁製帶101 設置於外薄膜10的縱方向的兩端間，故，藉由拉引裁製 -11 - 201033094 帶ιοί ’能夠將外薄膜10切斷於縱方向，並在寬度方向分 斷成二個。 內薄膜20係以一對薄膜20a、20b所構成。一對薄膜 20a、20b係在重疊於外薄膜1〇之狀態下，在與外薄膜1〇 的長方向正交的方向（寬度方向）橫向排列地配置著。再 者’在以下的說明，將配置於外薄膜10的寬度方向的一 端側之一方的薄膜2 0a稱爲第一內薄膜，將配置於外薄膜 10的寬度方向的另一端側之另一方的薄膜20b稱爲第二內 n 薄膜。 第一薄膜20a及第二薄膜10b，分別係以具有與外薄 膜10相同的熱接著性之泛用性薄膜所構成。第一內薄膜 20a及第二內薄膜20b，係形成爲縱長的四角形狀（長方 形狀），各自的寬度方向的長度被設定成較外薄膜10之 寬度方向的一半的長度若干長。 第一內薄膜20a係在使寬度方向的一端與外薄膜10 的寬度方向的一端一致、且使縱方向的兩端分別與外薄膜 0 1〇的縱方向的兩端一致之狀態被配置著，成爲寬度方向的 另一端側超過裁製帶101之配置。藉此，第一內薄膜20a 係覆蓋外薄膜10的寬度方向的一端側一半的內面側全區 域。又，第一內薄膜2 0a係寬度方向的一端部、和從縱方 向的兩端部之寬度方向的一端部至裁製帶的附近爲止 的部位，對外薄膜10以預定寬度熱接著（熱封）著。 相對於此，第二內薄膜2 0b係在使寬度方向的一端與 外薄膜10的寬度方向的另一端一致、且使縱方向的兩端 -12- 201033094 分別與外薄膜10的縱方向的兩端一致的狀態下被配置， 成爲寬度方向的另一端側超過裁製帶101之狀態。藉此， 第二內薄膜2 0b係覆蓋外薄膜10的寬度方向的另一端側 一半的內面側全區域。又，第二內薄膜20b係寬度方向的 一端部、和從縱方向的兩端部之寬度方向一端部至裁製帶 101的附近爲止的部位，對外薄膜1〇以預定寬度熱接著（ 熱封）著。 Φ 藉此，上述結構的米飯加工食品用包裝材1係成爲第 —內薄膜2 0a及第二內薄膜20b的另一端側彼此在外薄膜 10的寬度方向中央部呈非接著的方式相互重疊之狀態，第 一內薄膜20a及第二內薄膜2 0b係構成爲與外薄膜10同 樣之在平面視角呈縱長之四角形狀（長方形狀）的內薄膜 10。又，該內薄膜20(第一內薄膜20a及第二內薄膜2 0b )係與外薄膜10相互合作來形成袋部150。在袋部150的 內部，形成有從外部所區劃的空間。又，藉由第一內薄膜 • 20a及第二內薄膜20b的另一端側彼此對應於外薄膜10的 寬度方向中央部而相互重疊，成爲第一內薄膜2 0a與第二 內薄膜2 0b之重疊的部分係與裁製帶101相對應的配置。 再者，圖示的米飯加工食品用包裝材1，係第一內薄 膜2 0a的寬度方向的一端部與外薄膜10的寬度方向的一 端部在縱方向被斷續地熱接著，並且第一內薄膜20a的寬 度方向的一端部與外薄膜10的寬度方向的另一端部在縱 方向被斷續地熱接著。即，本實施形態之米飯加工食品用 包裝材1，第一內薄膜20a的寬度方向的一端部與外薄膜 -13- 201033094 ίο的寬度方向的一端部係在縱方向以隔著間隔之複數個部 位進行熱接著，並且第一內薄膜20a的寬度方向的一端部 與外薄膜10的寬度方向的另一端部係在縱方向以隔著間 隔的複數個部位進行熱接著。藉此’在被熱接著之部位（ 熱接著部Hsl、Hs2)間將袋部150的內部與外部連通’ 可使袋部150內的空氣釋放到外部。 又，上述結構的米飯加工食品用包裝材1，爲第一內 薄膜20a與第二內薄膜20b之相互重疊的另一端側彼此呈 相互非接著的狀態’故，當以裁製帶將外薄膜分 割於寬度方向時，構成內薄膜20之第一內薄膜20a及第 二內薄膜2 0b成爲可相互朝寬度方向分離（遠離）。即， 上述結構的米飯加工食品用包裝材1，當以裁製帶1 〇 1將 外薄膜10的寬度方向中央部朝縱方向切斷時，則可分割 成：外薄膜10的寬度方向的一端側一半與第一內薄膜20a 以熱接著部Hsl成爲一體者、和外薄膜10的寬度方向的 另一端側一半與第二內薄膜20b以熱接著部Hs2成爲一體 者。 又，外薄膜10及內薄膜20分別如上述般，以形成爲 在平面視角呈四角形狀（長方形狀）爲前提，於四角部分 形成有缺口部160…。即，在將外薄膜1〇及內薄膜20重 疊而形成之米飯加工食品用包裝材1的各角部，設有缺口 部160·"。各缺口部160…係以延伸於與寬度方向正交的 縱方向之直線部160a、和從該直線部160a朝外側傾斜之 傾斜部160b所劃定的。各缺口部160係形成於米飯加工 201033094 食品用包裝材1的四角部分的熱接著部Hsl、Hs2內。直 線部160a係形成爲與米飯加工食品用包裝材1的縱方向 即與裁製帶101平行地朝向開封方向，傾斜部160b係形 成爲直線狀，使得在傾斜方向與直線部160a相連而到達 米飯加工食品用包裝材1的側端部。 本實施形態之米飯加工食品用包裝材1係由以上的結 構所構成，爲了使用上述米飯加工食品用包裝材1來包裝 ® 米飯加工食品RF，而預先將薄片狀食品SF (例如海苔） 收容於袋部150內。 再者，爲了將薄片狀食品SF收容於袋部150，在米 飯加工食品用包裝材1的製作過程，將薄片狀食品SF配 置於外薄膜10的內面側後，在此薄片狀食品SF重疊內薄 膜20 (第一內薄膜20a及第二內薄膜20b )之狀態下予以 配置，再將外薄膜10及內薄膜20a的周緣部彼此予以熱 接著（熱封）即可。又，薄片狀食品SF，需要具有能夠 覆蓋米飯加工食品RF的全面左右之大小，在此，使用與 袋部150內的空間的形狀所對應之四角形狀者。再者，圖 示的薄片狀食品SF，其縱方向的一端側的兩角部被切除 〇 又，在內薄膜20的內面側，配置有捏成適合食用的 大小、且呈三角形狀之米飯加工食品RF。此時，米飯加 工食品RF係配置於米飯加工食品用包裝材1的縱方向的 —端部側。具體而言，米飯加工食品RF係如圖4所示， 將其一個頂部在朝向縱方向的一端側之狀態下配置於米飯 -15- 201033094 加工食品用包裝材1的寬度方向中央部、且比起縱方向的 中央部更偏靠一端側之位置。 又，在將米飯加工食品RF搭載於內薄膜20 (第一內 薄膜20a、第二內薄膜20b)之狀態，將米飯加工食品用 包裝材1的縱方向的一端側之寬度方向的兩側2、3折彎 。即，將米飯加工食品用包裝材1的縱方向的一端側之寬 度方向的一端側（第一部位）2沿著構成米飯加工食品RF 的外周之傾斜面（位於縱方向的一端側之頂部的兩側的傾 @ 斜面中之其中一方的傾斜面），朝圖4中的a方向折彎， 使該折彎的第一部位2與米飯加工食品RF接觸。同樣地 ，將米飯加工食品用包裝材1的縱方向的一端部之寬度方 向的另一端側（第二部位）3沿著構成米飯加工食品RF 的外周的傾斜面（位於縱方向的一端側之頂部的兩側的傾 斜面中之另一方的傾斜面）朝圖中的b方向折彎，使該折 彎的第二部位3與米飯加工食品RF接觸。 接著，以米飯加工食品用包裝材1的縱方向的另一端 © 側之一半，被覆米飯加工食品RF。即，將米飯加工食品 用包裝材1的縱方向的另一端側之一半，沿著米飯加工食 品RF朝圖4中的c方向折彎，使該折彎的部位與米飯加 工食品RF接觸，作成爲如圖5所示的這種狀態。接著’ 折彎米飯加工食品用包裝材1的縱方向的另一端部之寬度 方向的兩側4、5。即，將米飯加工食品用包裝材1的縱方 向的另一端部之寬度方向的一端側（第三部位）4 '沿著米 飯加工食品RF的前述一方的傾斜面，朝圖5中的d方向 -16- 201033094 折彎，使該折彎的第三部位4重疊於第一部位2的外面。 同樣地，將米飯加工食品用包裝材1的縱方向的另一端部 之寬度方向的另一端側（第四部位）5，沿著米飯加工食 品RF的前述另一方的傾斜面朝圖中的e方向折彎，使該 折彎的第四部位5重疊於第二部位3的外面。再者，米飯 加工食品用包裝材1係第一部位2與第三部位4之間、第 二部位3與第四部位5之間，分別藉由熱接著等呈點狀接 0 著並加以保持爲佳。 其結果，米飯加工食品用包裝材1係如圖6所示，包 覆成覆蓋米飯加工食品RF的全面。此時，米飯加工食品 用包裝材1的第三部位4與第四部位5之間，係以封條3 0 跨越的方式被黏貼並固定。藉此，米飯加工食品用包裝材 1係在覆蓋米飯加工食品RF之狀態下被保持。該情況係 如圖示般，當將封條30的一部亦與外薄膜10接觸地黏貼 時，則米飯加工食品用包裝材1的固定會變得更完全。再 • 者，封條30可適宜地選擇紙製者、樹脂製者、或將紙與 樹脂予以複合而成者等來使用。 . 又，在食用以米飯加工食品用包裝材1所包裝之米飯 _ 加工食品的情況，拆除裁製帶1 〇 1，將外薄膜1 0分斷成二 個。即，爲了在將薄片狀食品SF收容於袋部150之狀態 下，將包裝有米飯加工食品RF之米飯加工食品用包裝材 1開封，可利用經由米飯加工食品用包裝材1的其中任一 端側（在本實施形態爲縱方向的另一端側）的摘取部1 03 ，抓住裁製帶101的端部，朝米飯加工食品用包裝材1的 -17- 201033094 其中任另一端側（本實施形態爲縱方向的一端側）拉引。 於是，外薄膜10伴隨裁製帶101的進行而沿著該裁製帶 101被切斷，或與裁製帶101成爲一體而一部分被拆除。 其結果，外薄膜10，其寬度方向中央部朝縱方向呈直線地 被切斷，米飯加工食品用包裝材1被分割成寬度方向的一 端側一半與另一端側一半。 然後，當將米飯加工食品用包裝材1朝寬度方向拉引 時，在薄片狀食品SF被覆於米飯加工食品RF之狀態下， 這些食品露出。即，當抓住外薄膜1〇的寬度方向的一端 側一半的頂部並朝一端側外側拉引時，受到熱接著部Hs 1 所接著之第一內薄膜2 0a與外薄膜10的寬度方向的一端 側一半被一同地拆除。此時，由於第一內薄膜20a位於米 飯加工食品RF與薄片狀食品SF之間，故，其內面在米飯 加工食品RF的表面上滑動且外面在薄片狀食品SF上滑動 而朝寬度方向的一端側移動，進而朝外側被拆除。因此， 如圖7所示，米飯加工食品RF的寬度方向的一端側一半 在被薄片狀食品SF所覆蓋的狀態下露出。 接著，將薄片狀食品SF作成爲按壓於.寬度方向的一 端側一半的米飯加工食品RF之狀態後以手予以握持，與 前述同樣地，當抓住外薄膜10的寬度方向的另一端側一 半的頂部並朝寬度方向的另一端側外側拉引時，則被熱接 著部Hs2所接著之第二內薄膜2 0b與外薄膜10的寬度方 向的另一端側一半一同地被拆除。此時，由於第二內薄膜 2 0b位於米飯加工食品RF與薄片狀食品SF之間，故其內 201033094 面滑動於米飯加工食品RF的表面上且外面滑動於薄片狀 食品SF上而朝寬度方向的另一端側移動，進而朝外側被 拆除。因此，米飯加工食品RF的寬度方向的另一端側一 半也在被薄片狀食品SF所覆蓋的狀態下露出。 如此，本實施形態之米飯加工食品用包裝材1，能夠 簡單地作成爲下述狀態，即，米飯加工食品RF的全體被 薄片狀食品SF所覆蓋的狀態，也就是能夠將米飯加工食 # 品RF與薄片狀食品SF —同食用之狀態。再者，本實施形 態之米飯加工食品用包裝材1，亦可從寬度方向的另一端 側一半拆除，但如上述般，作成爲先拆除米飯加工食品用 包裝材1的寬度方向的一端側一半的狀態爲佳。即，由於 該米飯加工食品用包裝材1，第一內薄膜20a的寬度方向 的另一端側呈不與米飯加工食品RF接觸的狀態，故，藉 由先拉引米飯加工食品用包裝材1的寬度方向的一端側一 半，能夠使第一內薄膜20a與米飯加工食品RF之間的摩 ® 擦阻抗變小，能儘可能地抑制米飯加工食品RF的形狀崩 潰。 如以上所述，由於本實施形態之米飯加工食品用包裝 材1，係在將薄片狀食品SF收容於袋部150內之狀態下 包住米飯加工食品RF，故，在食用米飯加工食品前，薄 片狀食品SF不會與米飯加工食品RF接觸。因此，當處於 包裝狀態時，薄片狀食品SF不會因米飯加工食品RF的水 分而受潮，不會有損薄片狀食品SF的風味，能夠將該薄 片狀食品SF和米飯加工食品RF —同可口地食用。 -19- 201033094 又’由於形成爲以相互非接著的方式重疊之第一內薄 膜20a及第二內薄膜20b的另一端側是與裁製帶1〇1相對 應之配置，故，使外薄膜10的各一半分離的同時，可一 倂使第一內薄膜2 0a與第二內薄膜20b分離。藉此，拆除 外薄膜10與內薄膜20( —對薄膜2 0a、2 0b)的同時，可 作成爲將薄片狀食品SF被覆於米飯加工食品RF之狀態也 就是可將這些食品一同食用之狀態。 又，本實施形態之米飯加工食品用包裝材1，能夠容 @ 易且確實地進行開封。 即，本實施形態之米飯加工食品用包裝材1係藉由在 外薄膜10及內薄膜20的四角部分設置缺口部160··.，如 圖6所示，能夠縮小在裁製帶101所處的寬度方向中央部 之第三部位4與第四部位5之重疊部G。即，米飯加工食 品用包裝材1，藉由在各角部設置以直線部160a與傾斜部 160b所劃定的略梯形狀的缺口部160···，能夠使第三部位 4、及第四部位5的各角部消失，故，處於包裝狀態時的 ◎ 米飯加工食品用包裝材1的角部彼此的重疊會消失。因此 ，在裁製帶1〇1切斷外薄膜1〇之線上成爲切斷之阻礙者 ，除了封條30以外，其餘均消失。因此，當進行開封時 ，重疊部G不會妨礙裁製帶101的行進，故，容易進行利 用裁製帶之外薄膜的切斷，可確實地進行米飯加 工食品用包裝材1的分斷。 又，本實施形態之米飯加工食品用包裝材1，能夠增 加包裝方向。·ΒΡ ’由於在米飯加工食品用包裝材1的縱方 -20- 201033094 向之兩端部的兩角部設置缺口部160…，並且在裁製帶 101的縱方向的兩端部設有摘取部103，故，亦可將第一 及第二部位2、3重叠於米飯加工食品用包裝材1的第三 及第四部位4、5的外面側的方式進行包裝。即，在本實 施形態，由於使第三及第四部位4、5重疊於米飯加工食 品用包裝材1的第一及第二部位2、3的外面側，故，設 置於米飯加工食品用包裝材1的縱方向的另一端側的兩角 # 部之缺口部160…能夠大幅地減少第三及第四部位4、5的 重疊部G。與此同樣地，即使在將第一及第二部位2、3 重疊於米飯加工食品用包裝材1的第三及第四部位4、5 的外面側之情況，設置於米飯加工食品用包裝材1的縱方 向的一端側的兩角部之缺口部160…也能夠大幅地減少第 一及第二部位2、3的重叠部G。 因此，本實施形態之米飯加工食品用包裝材1’即使 從縱方向的任一半被覆（覆蓋）米飯加工食品RF’也能 Φ 夠縮小在裁製帶101的線上之米飯加工食品用包裝材1的 重疊部G，故，不需要進行包裝作業時之米飯加工食品用 包裝材1的縱方向的判斷。 其次，參照圖8、及圖9’說明關於本發明的第二實 施形態之米飯加工食品用包裝材。圖8係顯示米飯加工食 品用包裝材的內裝側之槪略裏面圖’圖9係圖8之B-B線 斷面圖。再者，從各圖得知，本實施形態之米飯加工食品 用包裝材的基本結構係與第一實施形態之米飯加工食品用 包裝材共通，故，針對與第一實施形態共通的部分省略其 -21 - 201033094 說明，針對不同的結構爲主進行說明。又’爲了方便說明 ，對於與第一實施形態之米飯加工食品用包裝材的結構相 同或相當者，賦予與第一實施形態的各結構相同名稱’並 賦予相同符號。 該米飯加工食品用包裝材1係構成內薄膜20之第一 內薄膜20a及第二內薄膜2 0b中的其中任一方之寬度方向 的另一端側被折返。本實施形態之米飯加工食品用包裝材 1係將第二內薄膜20b的寬度方向的另一端部折返，而形 響 成折返部21。藉此，本實施形態之米飯加工食品用包裝材 1係除了可達到與第一實施形態的米飯加工食品用包裝材 1相同的效果外，亦可達到不會傷及米飯加工食品RF而 能拆除米飯加工食品用包裝材1之效果。 即，本實施形態之米飯加工食品用包裝材1，由於在 第二內薄膜2 0b的寬度方向的另一端側形成折返部21，故 ，在將外薄膜10分割後，將米飯加工食品用包裝材1的 寬度方向的另一端側拉引之際，第二內薄膜20b對米飯加 〇 工食品RF剝離地朝寬度方向的另一端側移動。 即，如第一實施形態這種未形成有折返部之情況，當 第二內薄膜2 0b將米飯加工食品用包裝材1的寬度方向的 另一端側朝寬度方向外側拉引時，由於會與米飯加工食品 RF的表面摩擦進行移動，故會有拉引力作用於該摩擦的 部位，造成米飯加工食品RF的形狀崩潰之虞，但，本實 施形態之米飯加工食品用包裝材1，當拉引寬度方向的另 一端側一半時，第二內薄膜20b在米飯加工食品RF的表 -22- 201033094 面上，從折返部21的寬度方向的一端側（折線的部位） 朝另一端側，向180°的方向一邊剝離一邊移動》藉此，在 拆除米飯加工食品用包裝材1之際，不會有拉引力施加於 米飯加工食品RF的情況，因此，米飯加工食品RF的形 狀不會崩潰而能以經常整齊的狀態下維持著。 再者，在本實施形態，第一內薄膜2 0a，寬度方向的 另一端側位於第二內薄膜20b與外薄膜10之間而未與米 # 飯加工食品RF接觸。因此，當進行開封之際，將米飯加 工食品用包裝材1分斷後，從該一端側一半先拆除，則第 一內薄膜20a對米飯加工食品RF之摩擦少，故能有效地 防止米飯加工食品RF的形狀崩潰。 其次，根據圖1〇、及圖U，說明關於本發明的第三 實施形態之米飯加工食品用包裝材。圖1 〇係顯示米飯加 工食品用包裝材的內裝側之槪略裏面圖，圖11係圖1〇之 C-C線斷面圖。再者，從各圖亦可得知，本實施形態之米 • 飯加工食品用包裝材的基本結構係與第一及第二實施形態 之米飯加工食品用包裝材共通，故，針對與第一及第二實 施形態共通的部分省略其說明，針對不同的結構爲主進行 說明。又，爲了方便說明，對於與第一及第二實施形態之 米飯加工食品用包裝材的結構相同或相當者，賦予與第一 及第二實施形態的各結構相同名稱，並賦予相同符號。 第一內薄膜2 0a係如圖10、及圖11所示，呈較第二 實施形態之第一內薄膜20a寬度更廣的縱長的四角形狀。 相對於此，第二內薄膜20b係設定成與第二實施形態之第 -23- 201033094 二內薄膜2 0b相同的形態（形狀及尺寸）。 本實施形態之第一內薄膜20a，其超越第二內薄膜 20b的寬度方向的另一端之部位朝內面側折返而形成折返 部22。又，第二內薄膜2 0b，其超越第一內薄膜20a的折 線之部位朝內面側折返而形成折返部23。第一內薄膜20a 及第二內薄膜2 0b的各折線係形成於超越裁製帶101之位 置。又，第一內薄膜20a與第二內薄膜2 0b與係配置成在 與外薄膜1〇的寬度方向中央部相對應的位置，另一端側 @ (折返部22、23 )彼此相互地重疊。又，第一內薄膜20a 及第二內薄膜2 0b係對相互重叠的部分對向之部分（重疊 的相手側、外薄膜10)呈非接著的狀態，而相重叠的部分 以外之端部對外薄膜10的外周端部被熱接著著。 上述結構的米飯加工食品用包裝材1，除了與第一實 施形態作過說明之作用外，也能夠不會使米飯加工食品 RF受損地拆除米飯加工食品用包裝材1。即，本實施形態 之米飯加工食品用包裝材1，較在第二實施形態所說明之 © 米飯加工食品用包裝材1更能不會使米飯加工食品RF受 損地加以拆除。 具體而言，本實施形態之米飯加工食品用包裝材1， 由於在第一內薄膜20a及第二內薄膜20b各自的寬度方向 的另一端側形成有折返部22、23，故，在分斷外薄膜10 後，拉引寬度方向的一端側之際，第一內薄膜2 0a朝一端 側移動’來對米飯加工食品RF剝離。又，該米飯加工食 品用包裝材1係當拉引寬度方向的另一端側之際，第二內 -24- 201033094 薄膜20b朝另一端側移動，來對米飯加工食品RF剝離。 因此，本實施形態之米飯加工食品用包裝材1，係不 僅如第一實施形態拉引第二內薄膜20b的另一端側時，且 在拉引第一內薄膜20a的一端側時，拉引力均不會施加於 米飯加工食品RF，故，米飯加工食品RF的形狀不會崩潰 而能以經常整齊的狀態下維持著。 再者，本實施形態之米飯加工食品用包裝材1，由於 Φ 第一內薄膜20a的折返部22位於較第二內薄膜20b的折 返部2 3外面側（外薄膜10側），故，米飯加工食品用包 裝材1從寬度方向的一端側一半拆除爲佳。即，由於米飯 加工食品用包裝材1係成爲第二內薄膜20b的另一端側重 疊於第一內薄膜20a的寬度方向的另一端側而該第一內薄 膜2 0a的另一端側未與米飯加工食品RF接觸的狀態，故 ，藉由先拉引米飯加工食品用包裝材1的寬度方向的一端 側一半，能夠縮小第一內薄膜20a與米飯加工食品RF之 • 間的摩擦阻抗。 其次，依據圖12〜圖15，說明關於本發明的第四實 . 施形態之米飯加工食品用包裝材。圖1 2係顯示米飯加工 食品用包裝材的內裝側之槪略裏面圖，圖1 3係顯示米飯 加工食品用包裝材的外裝側之槪略表面圖。又，圖14係 以米飯加工食品用包裝材包裝了米飯加工食品的狀態之背 面圖，圖15係以米飯加工食品用包裝材包裝了米飯加工 食品的狀態之正面圖。再者，從各圖得知，本實施形態之 米飯加工食品用包裝材的基本結構係與第一實施形態之米 -25- 201033094 飯加工食品用包裝材共通，故，針對與第一實施形態共通 的部分省略其說明，針對不同的結構爲主進行說明。又， 爲了方便說明，對於與第一實施形態之米飯加工食品用包 裝材的結構相同或相當者，賦予與第一實施形態的各結構 相同名稱，並賦予相同符號。 本實施形態之米飯加工食品用包裝材1係如圖1 2及 圖13所示，與第一實施形態同樣地，外薄膜10及內薄膜 20形成爲在平面視角呈四角形狀，在外薄膜1〇及內薄膜 @ 20的四角部分（4個角部）形成有缺口部160…。又，前 述外薄膜10及內薄膜20係設有從劃定前述缺口部160··· 之直線部160a朝內側延伸之複數個切痕6…。本實施形態 之米飯加工食品用包裝材1係藉由設置前述複數個切痕6 …，當進行開封時可緩和作用於裁製帶101之阻抗，防止 裁製帶101的斷裂。 又，本實施形態之米飯加工食品用包裝材1係如圖14 、及圖15所示，在包裝了米飯加工食品之狀態下，於前 ❹ 述外薄膜10的表面的至少1部位黏貼有封條30、35。該 封條30、50係可適宜地選擇因應所黏貼的部位顯示預定 的資訊（米飯加工食品的內容物之種類、開封順序等）者 '素色者、實施有設計圖案等者來加以採用。 前述封條30、35可形成爲四角形狀、圓形狀、三角 形狀、星形狀、鑽石形狀等的各種形態。即，封條3 0、3 5 可因應用途、黏貼的部位等，設定成適宜的形狀。 前述封條30、35係在周緣部設有複數個切痕31..·、 -26- 201033094 36···，藉由此切痕3 1···、36··· ’能夠緩和進行開封時作用 於裁製帶101之阻抗，防止裁製帶101的斷裂。即，當將 標籤等的封條對應於裁製帶101的配置而黏貼時，該封條 的存在會阻礙裁製帶101的行進，但由於本實施形態之封 條30、35在周緣部設有複數個切痕31…、36·.·，故，即 使對應於裁製帶101的配置而進行黏貼，也可在裁製帶 101的行進中變得容易切斷。藉此，前述封條30、35係可 Φ 防止當開封時裁製帶101在途中斷裂。 又，如圖14所示，本實施形態之米飯加工食品用包 裝材1係除了與第一實施形態同樣地包裝了米飯加工食品 ，並且在米飯加工食品用包裝材1的縱方向的另一端側一 半重疊一端側，而將該重叠的部分固裝於位於其下側之米 飯加工食品用包裝材1的部分，此固裝係使用前述封條30 。再者，該封條30，由於黏貼於包裝狀態之背面側，故例 如亦可印刷製造日期、價格等的資訊。 Φ 又，如圖15所示，在米飯加工食品用包裝材1的表 面側（外薄膜1 〇的表面側）黏貼前述封條3 5。再者，該 封條3 5，由於黏貼於包裝狀態之正面側，故可顯示商品名 稱、米飯加工食品RF的內容物之種類、開封手段100之 開封方法等爲佳。又，黏貼於正面之封條35的片數爲1 片或1片以上均可，因應顯示的種類設定片數即可。再者 ，前述封條30、35，可利用作業者之手作業進行黏貼’亦 可使用貼標籤機等以機械性的方式進行黏貼’如此可更進 一步提高生產效率。 -27- 201033094 在本實施形態，黏貼印刷有內容物等之封條3 5。因此 ，不需要使用進行因應米飯加工食品RF的內容物種類之 顯示的米飯加工食品用包裝材1。藉此，能以一種類的米 飯加工食品用包裝材1對應數種之內容物，故不需要如以 往般預先庫存數種的米飯加工食品用包裝材1，能夠減低 進行管理所需之作業，並且能夠連續地使用一種類的米飯 加工食品用包裝材1，故即使內容物改變，也不需要變更 製程等，能夠大幅地提昇生產性。再者，在前述的說明， 在米飯加工食品用包裝材1的外薄膜10的表面側，黏貼 顯示米飯加工食品RF的內容物之種類等的封條3 5，但， 對於共通部分（例如設計圖案部分等），亦可與以往同樣 地藉由凹板印刷等的印刷來加以實施。 其次，依據圖16〜圖19，說明關於本發明的第五實 施形態之米飯加工食品用包裝材。圖16係顯示米飯加工 食品用包裝材的內裝側之槪略裏面圖，圖17係顯示米飯 加工食品用包裝材1的外裝側之槪略表面圖。又，圖18 係米飯加工食品用包裝材的說明圖，其中（a)爲包裝了 米飯加工食品之狀態的斜視圖、（b )爲開封時的斜視圖 。圖19係開封後的斜視圖。再者，從各圖得知，本實施 形態之米飯加工食品用包裝材的基本結構係與第一至第四 實施形態之米飯加工食品用包裝材共通，故，針對與第一 至第四實施形態共通的部分省略其說明，針對不同的結構 爲主進行說明。又，爲了方便說明，對於與第一至第四實 施形態之米飯加工食品用包裝材的結構相同或相當者，賦 -28- 201033094 予與第一至第四實施形態的各結構相同名稱，並賦予相同 符號。 本實施形態之開封手段1 00係如圖1 6及圖1 7所示， 具備有以延伸於前述縱方向的方式被接著於外薄膜10之 至少2條的裁製帶101a、101b。又，本實施形態之開封手 段1〇〇，係與第一至第四實施形態同樣地，除了裁製帶 101a > l〇lb 外，亦具備有切口 102、102。 Φ 2條的裁製帶101a、101b係設置成與外薄膜10的縱 方向的至少一部位相互地交叉。在本實施形態，前述2條 的裁製帶l〇la、101b係配置成：在以位於外薄膜10的縱 方向的一端側之切口 102、102所形成的摘取部103附近 位置交叉（第一交叉部C1)後，朝向米飯加工食品用包 裝材1的縱方向的另一端側描繪圓弧地逐漸遠離，而在比 起該米飯加工食品用包裝材1的縱方向的中央更靠近另一 端側之部位，一邊描繪圓弧一邊逐漸接近而再次交叉（第 • 二交叉部C2)後，再次朝另一端側描繪圓弧地逐漸遠離 。換言之，2條的正弦波狀的裁製帶101a、101b係處於經 由交叉部Cl、C2使相互的山部與谷部相對向之狀態。 因此，能夠將「具有與從雨裁製帶l〇la、101b的山 部的頂部位與谷部的最深部位所形成的最大遠離距離大致 相同之寬度」的開口形成於米飯加工食品用包裝材1的外 薄膜10。 本實施形態之米飯加工食品用包裝材1係由以上結構 所構成，與第一至第四實施形態相同的方式包裝米飯加工 -29- 201033094 食品。又，在取出米飯加工食品RF加以食用之際，如圖 18(a)所示，首先，抓住摘取部103並朝正前方拉引， 以裁製帶l〇la、101b將外薄膜10切斷於縱方向。再者， 使用2條的裁製帶101將封條30與米飯加工食品用包裝 材1—同切斷之封條30，其係被黏貼成位於下端部遠離之 2條的裁製帶101重疊（一部分成爲一體）交叉部C2附 近。 藉此，如上述般，在以裁製帶l〇la、101b將外薄膜 0 10切斷於縱方向之際，如圖18(b)所示，藉由將被2條 的裁製帶101所分散的拉裂力，當分斷封條30之際暫時 集中於封條30的一部位（P)，使得米飯加工食品用包裝 材1與封條30 —同被切斷。 又，如上述般，經由交叉部Cl、C2而形成爲一條， 更進一步將米飯加工食品用包裝材1的一部位與條30雙 方拉裂之裁製帶101，之後會再次一邊遠離一邊切斷米飯 加工食品用包裝材1，因此，如圖19所示，具有較裁製帶 〇 101本身的寬度尺寸更廣之寬度的開口形成於米飯加工食 品用包裝材1。 然後，當將被分割於寬度方向之米飯加工食品用包裝 材1分別朝遠離的方向（箭號E)拉引時，這些包裝材拆 除，捲繞有薄片狀食品SF之米飯加工食品RF露出。在本 實施形態，藉由形成較裁製帶l〇la、101b本身的寬度尺 寸更廣的寬度之開口，可使米飯加工食品用包裝材1對米 飯加工食品RF之被覆面積變小，如上述般，可使將已被 -30- 201033094 分割之米飯加工食品用包裝材1朝遠離方向拉引之際的對 米飯加工食品RF之摩擦阻抗變小，能夠圓滑地拆除所残 留之米飯加工食品用包裝材1。 因此，本實施形態之米飯加工食品用包裝材，具有容 易且可瞬間地取出米飯加工食品RF之優點。 再者，本發明之米飯加工食品用包裝材不限於上述各 實施形態，在不超出本發明的技術思想範圍內，可進行各 φ 種變更。 即，外薄膜10、及內薄膜20的材質未特別限定。例 如，可使用聚丙烯製、聚乙烯製等的泛用薄膜。再者，內 薄膜20 ( —對薄膜20a、20b )，係與米飯加工食品RF之 分離效果好的聚乙烯製者爲佳，但，若不會使濕氣通過且 與米飯加工食品RF之分離效果好者即可。 又，在上述各實施形態，以三角形狀的米飯加工食品 RF作爲對象，但不限於此，亦可將例如加工成圓柱體狀 • 之米飯加工食品作爲對象。 又，在上述各實施形態，將缺口部160形成於外薄膜 10及內薄膜20的四角部分，但，亦可形成於外薄膜10及 內薄膜20的在寬度方向相鄰的二角部分。 且，在上述各實施形態，採用裁製帶101、101a、 101b，作爲開封手段100的一結構，但，開封手段100不 限於此，亦可例如將延伸於外薄膜10的縱方向之撕線隔 著間隔成對地形成於寬度方向，來作爲開封手段100。藉 此，由於可藉由成對之兩撕線，來切斷外薄膜10，故，能 -31 - 201033094 夠將撕線間切除成帶狀，而與裁製帶101、l〇la、101b同 樣地可切斷外薄膜10。特別是在以延伸薄膜構成外薄膜 10之情況，開封手段100，亦可不設置裁製帶101，而僅 以設置於外薄膜10的縱方向的兩端中的至少其中任一方 的端部之一對切口 1 02、1 02來構成。例如，在以單軸延 伸薄膜、或雙軸延伸薄膜，或以單軸延伸薄膜與無配向薄 膜之層積品，或以雙軸延伸薄膜與無配向薄膜之層積品來 形成外薄膜10之情況，即使無裁製帶101，亦可僅抓住形 @ 成於切口 102、102間之摘取部103加以拉引，能夠在該 切口 102、102間的寬度朝縱方向切斷外薄膜10，因此能 夠維持開封之容易性。又，在外薄膜10使用延伸薄膜之 情況，與上述情況相反地，開封手段1 00，亦可不設置切 口 102、102，而僅以裁製帶101來構成。 在上述各實施形態，採用以直線部1 60a與傾斜部 160b所劃定之缺口部160，但此缺口部160不限於此形狀 ，例如，亦可爲以直線狀或略圓弧狀的端緣（邊緣）加以 ⑩ 劃定者。又，亦可如圖20所示，從米飯加工食品用包裝 材1的縱方向的一端6a (及/或另一端6b)朝寬度方向 的一端6c (及/或另一端6b)延伸之大致呈鋸齒刃狀的 邊緣9e來劃定缺口部160…。再者，此邊緣9e，亦可行 成爲通過直線狀或略圓弧狀（未圖示）的線上。 在上述各實施形態，將構成內薄膜20之第一內薄膜 2 0a與第二內薄膜2 0b的重叠部分（對應於外薄膜1〇的寬 度方向的中央部之重疊部分）以非接著的方式構成，但， -32- 201033094 不限於此，亦可例如’將第一內薄膜20a與第二內薄膜 2 0b之重疊部分可剝離地予以弱密封。該弱密封，亦可將 第一內薄膜20a與第二內薄膜20b在縱方向隔著間隔的複 數個部位部分地進行’亦可以沿著縱方向的方式作成爲連 續的線狀。又’在上述各實施形態，將外薄膜10的外周 端部與內薄膜20的外周端部斷續地熱接著，但，不限於 此’亦可將外薄膜10的外周端部與內薄膜20的外周端部 # 予以連續地熱接著。 在上述各實施形態，以第一內薄膜20a與第二內薄膜 2 0b構成內薄膜20，但，亦可與外薄膜1〇同樣地，以一 片薄膜來構成內薄膜20。在此情況，作爲分離內薄膜20 之手段，形成撕線、半切痕即可。 在上述各實施形態，藉由在包裝了米飯加工食品RF 之（折彎成對應於米飯加工食品RF的形態）米飯加工食 品用包裝材1的重叠的部位（第三部位4、第四部位5) ® 黏貼封條3 0，維持對米飯加工食品RF之包裝狀態，但不 限於此，亦可例如圖21所示，將爲了與米飯加工食品RF 的形態對應而利用折彎（包裝）米飯加工食品用包裝材1 所形成之3個角部El、E2、E3呈帶狀地密封（熱封）， 再將各角部E1、E2、E3封裝即可。在此情況，亦將米飯 加工食品用包裝材1的重疊的部位（第三部位4、第四部 位5 )黏貼封條3 0，即可使對米飯加工食品RF之包裝變 得確實。 在上述第二至第五實施形態，折返構成內薄膜20之 -33- 201033094 第一內薄膜20a及第二內薄膜2 0b的至少其中任一方的寬 度方向的另一端側，但不限於此，亦可例如以與第一實施 形態同樣地構成。又，亦可將第一實施形態的米飯加工食 品用包裝材1的內薄膜20作成爲第二至第五實施形態的 形態。即，內薄膜20作成爲第一實施形態至第五實施形 態的其中任一形態均可。 在上述第五實施形態，將2條的裁製帶101a、101b 設置成在外薄膜10的縱方向的至少一部位相互地交叉， _ 但，並非一定需要將此2條的裁製帶101a、101b交叉。 例如，不使2條的裁製帶，而各自作成爲波形後再配置於 外薄膜10，或不使2條的裁製帶交叉而各自作成爲直線狀 再配置於外薄膜10。 【圖式簡單說明】 圖1係本發明的第一實施形態之米飯加工食品用包裝 材的裏面圖。 @ 圖2係第一實施形態之米飯加工食品用包裝材的表面 圖。 圖3係圖1之A-A線斷面圖。 圖4係顯示使用第一實施形態之米飯加工食品用包裝 材，包裝米飯加工食品之際的第一段階的圖。

Then (sealed) to the outer peripheral end portion of the outer film 10'. In this way, the film 10' and the inner film 20' other than the packaging material 1' of the rice processed food are formed into a bag portion 150' for accommodating the flaky food SF', and the rice processed food packaging material 1 is provided. There are means of opening. The opening means has various forms, and is generally bonded to the inner side of the II outer film 10' by a method of extending in a direction orthogonal to the width direction (hereinafter referred to as a longitudinal direction). 101', and a slit 102', 102' composed of a notch provided at both end portions of the outer film ίο' in a manner of holding the cutting tape ιοί'. - In order to package the rice processed food RF' with the rice processed food packaging material 1' having the above configuration, first, after the flaky food SF' is contained in the bag portion 150', the rice processed food is carried on the inner film 20 In this state, as shown in Fig. 24, the outer film 10' is covered with the whole of the rice processed food RF' and packaged. Then, the packaging material 1' for the rice processed food is adhered to the seal 30' such as a label, and the predetermined covering state is maintained, and the packaging operation is completed. In addition, in order to unpack the rice processed food packaging material 1' in which the rice processed food RF' is packaged, first, the outer film 10' is cut by pulling one end portion of the cutting tape 101' toward the other end side. It is divided into two in the width direction in the longitudinal direction. In this manner, the outer film 10' is divided into two portions of the packaging material 1' for rice processed food, and then the outer film 10' is pulled in the width direction, whereby one end side of the outer film 10' in the width direction is formed. One half and the -6-201033094 film 20 a' are integrated by the heat contact portion Hsl' (see FIGS. 22 and 23), and the outer film 10, the other end side in the width direction and the second film 20b The heat-receiving portion Hs2 (see FIGS. 22 and 23) is integrated, and each side is taken away. Then, the rice processed food RF' wound by the flaky food SF' is exposed, and the state of the food can be eaten together. [Explanation] [Problems to be Solved by the Invention] However, the packaging material 1' for rice processed food having the above configuration may be unsuccessfully opened. Specifically, in the packaging material for rice processed food having the above-described configuration, when the rice processed food RF' is packaged, the two corner portions 4' and 5 of one end portion of the rice processed food packaging material 1' in the longitudinal direction are formed. 'Overlapping parts G that overlap each other deeply. Therefore, when the cutting tape 101' is pulled, the overlapping portion G hinders the travel of the cutting tape 101', and the cutting tape 101' may be broken in the middle. Therefore, in such a case, it becomes impossible to divide the outer film 10' neatly, and the problem of spending time on the opening operation is caused. Therefore, the present invention has been developed to solve the above problems, and the object thereof is aimed at In order to provide a packaging material for rice processed food which can be easily and surely cut by the unsealing means and which can be easily divided and opened. 201033094 [Means for Solving the Problem] The packaging material for rice processed food of the present invention includes a film which can be formed by being divided into the width direction, and which is superposed on the outer film via the flaky food, and can be separated from The inner film formed in the same direction as the outer film, the outer peripheral end portions of the outer film and the inner film are sealed to surround the sheet-like food, and the inner film is used as the inside to package the rice processed food. Further, the present invention is characterized in that the outer film and the inner film are formed in a plane view angle in order to divide the outer film into a width direction and cut the outer film in a direction perpendicular to the width direction. A quadrangular shape, and a notch portion is formed at a dihedral portion or a quadrangular portion adjacent to each other in the width direction. In the state in which the inner film is made to be inside and the rice processed food is packaged together with the flaky food according to the above-described structure, the outer film is oriented perpendicular to the width direction by the opening method. After being divided into two in the width direction, the packaged material for rice processed food is pulled in the width direction, and the half of the width of the inner film and the outer film are integrally removed. Further, the packaging material for rice processed food having the above configuration can be easily and surely subjected to the above-described unsealing. In other words, by providing the notch portions at the two corner portions or the four corner portions adjacent to each other in the width direction of the outer film and the inner film, the rice processed food packaging material does not have a corner portion, and therefore, the contents can be packaged. The overlapping portion of the packaging material for rice processed food at the time point is very small. In other words, in the packaging material for rice processed food having the above configuration, since the overlapping of the corner portions in the package state disappears, the area of the overlap of the weight -8 - 201033094 can be substantially reduced. Therefore, when the outer film is cut by the unsealing means, the cut-off stopper is almost eliminated, and the opening can be smoothly opened. In addition, by providing a notch portion at a dihedral portion or a four-cornered portion adjacent to the width direction of the packaging material for the processed rice food (outer film and inner film), the package can be packaged in any direction from the longitudinal direction. Increased work efficiency. Further, when the notch portion is provided in the portion (the rear portion) where the outer film and the inner film are sealed, the sealing property can be ensured, so that the sealing state in the bag portion can be favorably maintained, and the sheet-like food is not externally sealed. The moisture is damp and extremely ideal. The outer film and the inner film may be provided with a plurality of slits extending inward from the edge of the notch portion. Thereby, it can reduce the action on the opening hand when opening the seal. The impedance of the segment makes the opening work easier. The opening and closing means may further include at least two cutting tapes provided on the outer film so as to extend in the longitudinal direction, and the at least two cutting tapes are disposed to cross each other in at least one of the longitudinal directions . Therefore, since at least two cutting tapes are provided to be gradually separated from each other at the intersection position, when the opening is performed, an opening having a wider width than the cutting tape itself can be formed, which is easy and possible. Instantly take out rice processed food. [Effect of the Invention] As described above, according to the present invention, it is possible to easily and reliably perform the cutting by the unsealing means, and to divide and unseal easily. [Embodiment] Hereinafter, a packaging material for rice processed food according to the first embodiment of the present invention will be described with reference to the drawings. Fig. 1 to Fig. 3 show a packaging material for rice processed food of the present embodiment. Fig. 1 is a schematic view showing the inner side of the packaging material for rice processed food, and Fig. 2 is a schematic top view showing the outer side of the packaging material for rice processed food shown in Fig. 1, Fig. 3 Figure 1 is a cross-sectional view taken along line AA of Figure 1. As shown in FIG. 1 to FIG. 3, the packaging material 1 for rice processed food of the present embodiment includes a film 1 可 which is formed to be separable in the width direction, and a flaky food SF which is interposed with seaweed or the like. The outer film 10 is formed into an inner film 20 which is formed apart from the outer film 10 in the same direction, and the outer peripheral ends of the outer film 1 and the inner film 20 are thermally (heat-sealed) to surround the sheet-like food SF. The outer film 10 is set to be sized to cover the rice processed food RF. In addition to the present embodiment, the film 10 is formed into a vertically long rectangular shape (rectangular shape) in a plan view angle. @ The outer film 1 is composed of a general-purpose film having thermal adhesion. Here, the general-purpose film may, for example, be a synthetic resin film such as polyethylene or polypropylene. Further, since the synthetic resin film has a uniaxially stretched synthetic resin film, a biaxially stretched synthetic resin film, and an unstretched synthetic resin film, a film having suitable characteristics can be selected depending on the application. Here, the uniaxially stretched synthetic resin film refers to a film having a property of being able to extend in one direction, and is a film having a property of being easily pulled in the extending direction but not easily pulled in a direction orthogonal thereto, and biaxial stretching synthesis Resin-10-201033094 A film is a film having a property of being able to extend in two directions orthogonal to each other, and has a property of being easily pulled in both directions. In the foregoing outer film ίο, an opening means 1 is provided. The unsealing means of this embodiment is constituted by a cutting tape 101 and a slit 102. The cutting tape ιοί is arranged so as to extend in the longitudinal direction in the central portion in the direction (width direction) orthogonal to the longitudinal direction (longitudinal direction) of the outer film ίο, and to reach the other end from one end in the longitudinal direction of the outer film 10. Further, the cutting tape 101 may be attached to one of the outer thin films 10, and in the present embodiment, is attached to the inner surface of the outer film 10 (the surface facing the inner film 20). Further, the cutting tape 101 is used to have a certain strength which is not easily cut. The slit 102 is provided at both end portions in the longitudinal direction of the portion of the film 10 which is located outside the film 10, and is placed in pairs in a state in which the cutting tape 101 is sandwiched. Further, the slits 102 and 102 are not limited to being provided at both end portions of the outer film 10 in the longitudinal direction, and may be provided only at one of the end portions. That is, the slits 102 and 102 may be provided at least at the end of the opening/side of the opening. Further, by the presence of the slits 102, 102, a pick-up portion 103 is formed at the end portion of the outer film 1 in the longitudinal direction, which corresponds to the end portion of the cut tape 1?. The slits 102 and 102 serve as a cutting opportunity for the outer film 10, and at the same time guide the cutting direction at the initial stage of opening. Therefore, when the picking portion 103 formed by the slits 102, 102 is taken out and pulled toward the other end side in the longitudinal direction, the cutting tape 101 is easily advanced in the initial direction of the outer film 1 ,, so The cutting of the outer film 10 can be performed smoothly. Since the cutting tape 101 is disposed between both ends of the outer film 10 in the longitudinal direction, the outer film 10 can be cut in the longitudinal direction and cut in the width direction by pulling the cut -11 - 201033094 with ιοί ' Into two. The inner film 20 is composed of a pair of films 20a and 20b. The pair of films 20a and 20b are arranged side by side in a direction (width direction) orthogonal to the longitudinal direction of the outer film 1 状态 in a state of being overlapped with the outer film 1 〇. In the following description, the film 20a disposed on one end side in the width direction of the outer film 10 is referred to as a first inner film, and is disposed on the other end side of the outer film 10 in the width direction. The film 20b is referred to as a second inner n film. The first film 20a and the second film 10b are each formed of a general-purpose film having the same thermal adhesion as the outer film 10. The first inner film 20a and the second inner film 20b are formed into a vertically long rectangular shape (rectangular shape), and the length in the width direction is set to be somewhat longer than the length of one half of the width direction of the outer film 10. The first inner film 20a is disposed such that one end in the width direction coincides with one end in the width direction of the outer film 10, and both ends in the longitudinal direction are aligned with the both ends of the outer film 0 1 纵 in the longitudinal direction. The other end side in the width direction is disposed beyond the cut tape 101. Thereby, the first inner film 20a covers the entire inner surface side of the one end side half of the outer film 10 in the width direction. Further, the first inner film 20a is one end portion in the width direction and a portion from the one end portion in the width direction of the both end portions in the longitudinal direction to the vicinity of the cutting tape, and the outer film 10 is thermally sealed at a predetermined width (heat sealing) ). On the other hand, the second inner film 20b is formed such that one end in the width direction coincides with the other end in the width direction of the outer film 10, and both ends in the longitudinal direction -12-201033094 and the longitudinal direction of the outer film 10 are respectively When the ends are aligned, the other end side in the width direction is out of the state of the cutting tape 101. Thereby, the second inner film 20b covers the entire inner surface side of the other end side half of the outer film 10 in the width direction. Further, the second inner film 20b is one end portion in the width direction and a portion from the one end portion in the width direction of the both end portions in the longitudinal direction to the vicinity of the cut tape 101, and the outer film 1 is thermally sealed at a predetermined width (heat sealing) ). Φ In this way, the packaging material 1 for rice processed food having the above-described structure is in a state in which the other end sides of the first inner film 20a and the second inner film 20b overlap each other in the central portion in the width direction of the outer film 10. The first inner film 20a and the second inner film 20b are formed into an inner film 10 having a rectangular shape (rectangular shape) which is vertically long in plan view angle, similarly to the outer film 10. Further, the inner film 20 (the first inner film 20a and the second inner film 20b) cooperate with the outer film 10 to form the pocket portion 150. Inside the pocket portion 150, a space partitioned from the outside is formed. Further, the other end sides of the first inner film 20a and the second inner film 20b overlap each other in correspondence with the central portion in the width direction of the outer film 10, and become the first inner film 20a and the second inner film 20b. The overlapping portions are configured corresponding to the cutting tape 101. In addition, the packaging material 1 for rice processed food shown in the drawing is one end portion in the width direction of the first inner film 20a and one end portion in the width direction of the outer film 10 is intermittently thermally stopped in the longitudinal direction, and the first inner portion One end portion in the width direction of the film 20a and the other end portion in the width direction of the outer film 10 are intermittently thermally contacted in the longitudinal direction. In the packaging material 1 for rice processed food of the present embodiment, one end portion in the width direction of the first inner film 20a and one end portion in the width direction of the outer film-13-201033094 are spaced apart in the longitudinal direction by a plurality of intervals. The portion is thermally heated, and the other end portion of the first inner film 20a in the width direction and the other end portion of the outer film 10 in the width direction are thermally joined in a plurality of portions spaced apart in the longitudinal direction. Thereby, the inside of the bag portion 150 is communicated with the outside between the portions (the heat-receiving portions Hs1 and Hs2) which are heated, and the air in the bag portion 150 can be released to the outside. Further, the packaging material 1 for rice processed food having the above configuration is such that the other end sides of the first inner film 20a and the second inner film 20b which are overlapped with each other are in a non-adjoining state with each other, so when the outer film is cut by the tape When divided in the width direction, the first inner film 20a and the second inner film 20b constituting the inner film 20 are separated from each other in the width direction (away from). In other words, when the packaging material 1 for rice processed food having the above-described structure is cut in the longitudinal direction at the central portion in the width direction of the outer film 10 by the cutting tape 1 〇1, it can be divided into one end in the width direction of the outer film 10. The side half is integrated with the first inner film 20a as the heat contact portion Hs1, and the other end side half of the outer film 10 in the width direction and the second inner film 20b are integrated by the heat contact portion Hs2. Further, as described above, the outer film 10 and the inner film 20 are formed so as to have a quadrangular shape (rectangular shape) in a plan view, and the notch portions 160 are formed at the four corner portions. In other words, at each corner portion of the packaging material 1 for rice processed food formed by stacking the outer film 1〇 and the inner film 20, a notch portion 160·" is provided. Each of the cutout portions 160 is defined by a linear portion 160a extending in the longitudinal direction orthogonal to the width direction and an inclined portion 160b inclined outward from the linear portion 160a. Each of the notch portions 160 is formed in the thermal joint portions Hs1 and Hs2 of the four corner portions of the rice processing 201033094. The straight portion 160a is formed so as to be parallel to the cutting direction of the rice processed food packaging material 1 in the longitudinal direction, and the inclined portion 160b is formed in a straight line so as to be connected to the straight portion 160a in the oblique direction to reach the rice. The side end portion of the packaging material 1 for processed foods. The packaging material 1 for rice processed food of the present embodiment is configured by the above-described configuration, and the flaky food SF (for example, seaweed) is previously stored in order to package the rice processed food RF using the packaging material 1 for rice processed food. Inside the pocket portion 150. In the process of producing the packaging material 1 for rice processed food, the flaky food SF is placed on the inner surface side of the outer film 10, and the flaky food SF is overlapped. The inner film 20 (the first inner film 20a and the second inner film 20b) is disposed, and the outer peripheral film 10 and the peripheral portion of the inner film 20a are thermally contacted (heat-sealed). Further, the flaky food SF needs to have a size that covers the entire range of the rice processed food RF, and a quadrangular shape corresponding to the shape of the space in the pocket portion 150 is used. In addition, in the flaky food SF shown in the figure, the corners on one end side in the longitudinal direction are cut off, and on the inner surface side of the inner film 20, rice having a triangular shape that is suitable for eating is disposed. Processed food RF. In this case, the rice processing food RF is placed on the end side in the longitudinal direction of the packaging material 1 for rice processed food. Specifically, as shown in FIG. 4, the rice processed food product RF is placed in the center portion in the width direction of the processed food packaging material 1 in the state of rice -15-201033094 in a state in which one of the top portions is in the longitudinal direction. The central portion in the longitudinal direction is located closer to the one end side. In the state in which the rice processed food product RF is mounted on the inner film 20 (the first inner film 20a and the second inner film 20b), both sides in the width direction of the one end side in the longitudinal direction of the rice processed food packaging material 1 are 2 3 bends. In other words, the one end side (first portion) 2 in the width direction of the one end side in the longitudinal direction of the packaging material 1 for rice processed food is along the inclined surface of the outer circumference of the rice processed food RF (the top side of the one end side in the longitudinal direction). The inclined surface of one of the inclined @ slopes on both sides is bent in the direction a in Fig. 4, so that the first portion 2 of the bend is in contact with the rice processed food product RF. In the same manner, the other end side (second portion) 3 in the width direction of one end portion of the packaging material 1 for rice processed food is along the inclined surface (the one end side in the longitudinal direction) constituting the outer periphery of the rice processed food RF. The other inclined surface of the inclined surfaces on both sides of the top is bent toward the b direction in the drawing, so that the bent second portion 3 is in contact with the rice processed food product RF. Next, the rice processed food RF is covered with one half of the other side of the longitudinal direction of the packaging material 1 for rice processed food. In other words, one half of the other end side in the longitudinal direction of the packaging material 1 for rice processed food is bent along the rice processed food RF in the direction c in FIG. 4, and the bent portion is brought into contact with the rice processed food RF to prepare. This is the state shown in Figure 5. Then, the both sides 4 and 5 in the width direction of the other end portion of the packaging material 1 in the longitudinal direction of the rice processed food are bent. In other words, the one end side (third portion) 4' in the width direction of the other end portion of the packaging material 1 for the rice processed food is along the inclined surface of the rice processed food RF toward the d direction in FIG. -16- 201033094 Bend so that the third portion 4 of the bend overlaps the outside of the first portion 2. In the same manner, the other end side (fourth portion) 5 in the width direction of the other end portion of the packaging material 1 for rice processed food is along the other inclined surface of the rice processed food RF toward the e in the drawing. The direction is bent such that the fourth portion 5 of the bend overlaps the outside of the second portion 3. Further, the packaging material for rice processed food 1 is held between the first portion 2 and the third portion 4, and between the second portion 3 and the fourth portion 5, and is held in a dot shape by heat or the like. It is better. As a result, the packaging material 1 for rice processed foods is as shown in Fig. 6, and is covered with a full range of rice processed food RF. At this time, the third portion 4 and the fourth portion 5 of the packaging material 1 for rice processed food are adhered and fixed so as to be spanned by the seal 30. Thereby, the packaging material 1 for rice processed food is held in a state of covering the rice processed food RF. In this case, when one portion of the seal 30 is also adhered to the outer film 10 as shown in the drawing, the fixing of the rice processed food packaging material 1 becomes more complete. Further, the seal 30 can be suitably used by selecting a paper maker, a resin maker, or a composite of paper and resin. . Moreover, in the case of eating rice _ processed food packaged in the packaging material 1 for rice processed food, the dicing tape 1 〇 1 is removed, and the outer film 10 is divided into two. In other words, the packaged material 1 for rice processed food containing the rice processed food RF is opened in a state in which the sheet-shaped food SF is stored in the bag portion 150, and any end side of the packaging material 1 for processing food through the rice can be used. (the other end side in the longitudinal direction of the present embodiment), the picking portion 101 is grasped, and the end portion of the cutting tape 101 is taken, and the other end side of the packaging material 1 for rice processed food is -17-201033094 In the embodiment, the one end side in the longitudinal direction is pulled. Then, the outer film 10 is cut along the cutting tape 101 as the cutting tape 101 proceeds, or is integrated with the cutting tape 101 and partially removed. As a result, the outer film 10 is cut linearly in the longitudinal direction at the center portion in the width direction, and the rice processed food packaging material 1 is divided into one end side half and the other end side half in the width direction. Then, when the rice processed food packaging material 1 is pulled in the width direction, the foodstuffs are exposed in a state where the flaky food SF is coated on the rice processed food RF. That is, when the top of the one end side half of the outer film 1 抓住 is grasped and pulled toward the one end side outer side, the first inner film 20a and the outer film 10 which are followed by the heat contact portion Hs 1 are oriented in the width direction. One end half was removed together. At this time, since the first inner film 20a is located between the rice processed food RF and the flaky food SF, the inner surface thereof slides on the surface of the rice processed food RF and the outer surface slides on the flaky food SF toward the width direction. One end side moves and is removed toward the outside. Therefore, as shown in Fig. 7, one end side half of the rice processed food RF in the width direction is exposed in a state covered by the sheet-like food SF. Next, the flaky food SF is pressed into. In the state of the rice processed food product RF at the one end side of the width direction, the hand is held by the hand, and the top of the other end side of the width direction of the outer film 10 is grasped and the other end side of the width direction is the same as described above. At the time of drawing, the second inner film 20b followed by the heat-receiving portion Hs2 is removed together with the other end side half of the outer film 10 in the width direction. At this time, since the second inner film 20b is located between the rice processed food RF and the flaky food SF, the inner surface of the 201033094 slides on the surface of the rice processed food RF and slides outside on the flaky food SF in the width direction. The other end side moves and is removed toward the outside. Therefore, the other end side of the width direction of the rice processed food RF is also exposed in a state covered by the flaky food SF. In this way, the packaging material 1 for rice processed food of the present embodiment can be easily placed in a state in which the whole of the rice processed food RF is covered with the flaky food SF, that is, the rice can be processed. RF is in the same state as the flaky food SF. In addition, the packaging material 1 for rice processed food of the present embodiment may be removed from the other end side in the width direction, but as described above, one end half of the width direction of the packaging material 1 for rice processed food is first removed. The status is better. In other words, the packaged material 1 for rice processed food has the other end side in the width direction of the first inner film 20a in a state of not being in contact with the rice processed food product RF. Therefore, the packaged material 1 for rice processed food is first pulled. One end side half of the width direction can reduce the frictional resistance between the first inner film 20a and the rice processed food RF, and can suppress the shape collapse of the rice processed food RF as much as possible. As described above, the packaging material 1 for rice processed food of the present embodiment encloses the rice processed food RF in a state in which the sheet-shaped food SF is contained in the bag portion 150, so that before the rice is processed, The flaky food SF does not come into contact with the rice processed food RF. Therefore, when in the packaged state, the flaky food SF is not dampened by the moisture of the rice processed food RF, and does not impair the flavor of the flaky food SF, and the flaky food SF and the rice processed food RF can be tasted together. Eat. -19- 201033094 Further, since the other end sides of the first inner film 20a and the second inner film 20b which are formed so as to overlap each other in a mutually non-adherent manner are arranged corresponding to the cutting tape 1〇1, the outer film is made While the respective halves of 10 are separated, the first inner film 20a and the second inner film 20b can be separated at a time. Thereby, the outer film 10 and the inner film 20 (the film 20a, 20b) are removed, and the flaky food SF is covered in the state of the rice processed food RF, that is, the food can be eaten together. . Moreover, the packaging material 1 for rice processed food of this embodiment can be opened easily and reliably. In other words, in the packaging material 1 for rice processed food of the present embodiment, the notch portion 160 is provided at the four corner portions of the outer film 10 and the inner film 20. As shown in Fig. 6, the overlapping portion G between the third portion 4 and the fourth portion 5 in the central portion in the width direction of the cutting tape 101 can be reduced. In other words, the packaged material 1 for rice processed food can be provided with the third portion 4 and the fourth portion by providing the notched portions 160··· defined by the straight portion 160a and the inclined portion 160b at the respective corner portions. Since the corner portions of the portion 5 disappear, the overlap between the corner portions of the packaging material 1 for rice processed foods in the packaged state disappears. Therefore, in the line where the cutting tape 1〇1 cuts the outer film 1〇, it becomes a hindrance of cutting, and the rest disappears except for the seal 30. Therefore, when the opening is performed, the overlapping portion G does not interfere with the progress of the cutting tape 101. Therefore, it is easy to cut the film other than the cutting tape, and the packaging of the rice processed food packaging material 1 can be surely performed. Further, the packaging material 1 for rice processed food of the present embodiment can increase the packaging direction.

In other words, in the present embodiment, the third and fourth portions 4 and 5 are placed on the outer surface side of the first and second portions 2 and 3 of the packaging material for rice processed food, and therefore, they are provided in the package for rice processed food. The notch portion 160 of the two corners of the other end side of the material 1 in the longitudinal direction can greatly reduce the overlapping portion G of the third and fourth portions 4 and 5. In the same manner, the first and second portions 2 and 3 are placed on the outer surface side of the third and fourth portions 4 and 5 of the packaging material 1 for rice processed food, and are provided in a packaging material for processed rice food. The notch portion 160 of the both corners on one end side in the longitudinal direction of the first aspect can also greatly reduce the overlapping portion G of the first and second portions 2, 3. Therefore, the packaging material 1' for rice processed food of the present embodiment can shrink the rice processed food RF' on the line of the cut tape 101 even if it is covered (covered) with the rice processed food RF'. In the overlapping portion G, it is not necessary to determine the longitudinal direction of the packaging material 1 for rice processed food when the packaging operation is performed. Next, a packaging material for rice processed food according to a second embodiment of the present invention will be described with reference to Figs. 8 and 9'. Fig. 8 is a schematic side view showing the inner side of the packaging material for rice processed foods. Fig. 9 is a sectional view taken along line B-B of Fig. 8. In addition, the basic structure of the packaging material for rice processed food of the present embodiment is the same as that of the packaging material for rice processed food of the first embodiment, and therefore, the portion common to the first embodiment is omitted. -21 - 201033094 Description, mainly for different structures. In addition, the structure of the package material for rice processed food of the first embodiment is the same as or equivalent to that of the first embodiment, and the same reference numerals are given to the same components as those of the first embodiment. The packaging material for rice processed food 1 is folded back at the other end side in the width direction of one of the first inner film 20a and the second inner film 20b which constitute the inner film 20. In the packaging material for rice processed food of the present embodiment, the other end portion in the width direction of the second inner film 20b is folded back to form the folded portion 21. In addition, the packaging material 1 for rice processed foods of the present embodiment can be removed in the same manner as the packaging material 1 for rice processed foods of the first embodiment, and can be removed without injuring the rice processed food RF. The effect of packaging material 1 for rice processed food. In the packaging material 1 for rice processed food of the present embodiment, the folded portion 21 is formed on the other end side in the width direction of the second inner film 20b. Therefore, after the outer film 10 is divided, the rice processed food package is packaged. When the other end side of the material 1 in the width direction is pulled, the second inner film 20b moves toward the other end side in the width direction of the rice-filled food product RF peeling. In other words, in the case where the folded portion is not formed as in the first embodiment, when the second inner film 20b pulls the other end side in the width direction of the rice processed food packaging material 1 outward in the width direction, The surface friction of the rice processed food RF is moved, so that the pulling force acts on the rubbing portion, causing the shape of the rice processed food RF to collapse. However, the packaging material for rice processed food of the present embodiment is pulled. When the other end side of the width direction is half, the second inner film 20b is on the surface of the table- 22-201033094 of the rice processed food RF, from the one end side (the portion of the fold line) in the width direction of the folded portion 21 toward the other end side, to 180 In the case where the rice processing food packaging material 1 is removed, the pulling force is not applied to the rice processed food RF. Therefore, the shape of the rice processed food RF does not collapse. It is maintained in a often neat state. Further, in the present embodiment, the first inner film 20a has the other end side in the width direction between the second inner film 20b and the outer film 10 and is not in contact with the rice processed food RF. Therefore, when the rice processed food packaging material 1 is cut off and then removed from the one end side, the first inner film 20a has less friction against the rice processed food RF, so that the rice processed food can be effectively prevented. The shape of the RF crashes. Next, a packaging material for rice processed food according to a third embodiment of the present invention will be described with reference to Fig. 1 and Fig. U. Fig. 1 shows a schematic inside view of the inner side of the packaging material for rice processing food, and Fig. 11 is a sectional view taken along line C-C of Fig. 1 . Further, as can be seen from the respective drawings, the basic structure of the packaging material for rice and rice processed food of the present embodiment is common to the packaging materials for rice processed foods of the first and second embodiments, and therefore The description of the common portions of the second embodiment will be omitted, and the different configurations will be mainly described. In the first embodiment and the second embodiment, the same reference numerals are given to the first and second embodiments, and the same reference numerals are given to the first and second embodiments. As shown in Figs. 10 and 11, the first inner film 20a has a vertically long quadrangular shape which is wider than the first inner film 20a of the second embodiment. On the other hand, the second inner film 20b is set to the same shape (shape and size) as the second inner film 20b of the second embodiment of the -23-201033094. In the first inner film 20a of the present embodiment, the portion beyond the other end in the width direction of the second inner film 20b is folded back toward the inner surface side to form the folded portion 22. Further, the second inner film 20b is folded back toward the inner surface side of the portion which is beyond the fold line of the first inner film 20a to form the folded portion 23. The respective fold lines of the first inner film 20a and the second inner film 20b are formed at positions beyond the cutting tape 101. Further, the first inner film 20a and the second inner film 20b are disposed at positions corresponding to the central portion in the width direction of the outer film 1A, and the other end sides @ (folded portions 22, 23) overlap each other. Further, the first inner film 20a and the second inner film 20b are in a non-contiguous state with respect to the overlapping portions (overlapping phase hand and outer film 10), and the ends other than the overlapping portions are externally The outer peripheral end of the film 10 is thermally sealed. In addition to the functions described in the first embodiment, the packaging material 1 for rice processed food having the above-described configuration can also be used to remove the packaging material 1 for rice processed food without damage to the rice processed food RF. In other words, the packaging material 1 for rice processed food of the present embodiment can be removed from the packaging material 1 for rice processed food described in the second embodiment without being damaged by the RF processed food. Specifically, the packaging material 1 for rice processed food of the present embodiment has the folded portions 22 and 23 formed on the other end side in the width direction of each of the first inner film 20a and the second inner film 20b. After the outer film 10 is pulled, the first inner film 20a is moved toward the one end side when the one end side in the width direction is pulled, and the rice processed food product RF is peeled off. In the case of the rice-processed food packaging material 1 when the other end side in the width direction is pulled, the second inner -24-201033094 film 20b is moved toward the other end side to peel off the rice processed food. Therefore, the packaging material 1 for rice processed food of the present embodiment is not only when the other end side of the second inner film 20b is pulled as in the first embodiment, but also when pulling the one end side of the first inner film 20a. Since it is not applied to the rice processed food RF, the shape of the rice processed food RF does not collapse and can be maintained in a constantly neat state. Further, in the packaging material 1 for rice processed food of the present embodiment, since the folded portion 22 of the Φ first inner film 20a is located on the outer surface side (the outer film 10 side) of the folded portion 2 3 of the second inner film 20b, the rice is It is preferable that the packaged material 1 for processed foods is removed from one end half of the width direction. In other words, the packaged material 1 for rice processed food is such that the other end side of the second inner film 20b overlaps the other end side in the width direction of the first inner film 20a, and the other end side of the first inner film 20a is not mixed with rice. Since the processed food is in contact with the RF, the frictional resistance between the first inner film 20a and the rice processed food RF can be reduced by first pulling the one end side half of the width direction of the food processing packaging material 1. Next, a fourth embodiment of the present invention will be described with reference to Figs. 12 to 15 . A package of rice processed foods. Fig. 1 is a schematic inside view showing the inner side of the rice processing food packaging material, and Fig. 1 is a schematic surface view showing the outer side of the rice processed food packaging material. In addition, Fig. 14 is a front view showing a state in which rice processed foods are packaged in a rice processed food packaging material, and Fig. 15 is a front view showing a state in which rice processed foods are packaged in a rice processed food packaging material. In addition, as for the first embodiment, the basic structure of the packaging material for rice processed food of the present embodiment is the same as that of the rice-processed food packaging material of the first embodiment. The common parts are omitted from the description, and the different structures are mainly described. In the same manner as or similar to the structure of the rice-processed food packaging material of the first embodiment, the same reference numerals are given to the same structures as those of the first embodiment. As shown in Figs. 12 and 13, the outer packaging film 10 and the inner film 20 are formed in a quadrangular shape in a plan view, and the outer film 1 is formed as shown in Figs. 12 and 13 in the first embodiment. And the four corner portions (four corner portions) of the inner film @20 are formed with notch portions 160. Further, the outer film 10 and the inner film 20 are provided with a plurality of slits 6 extending inward from the straight portion 160a defining the notch portion 160···. In the packaging material 1 for rice processed food of the present embodiment, by providing the plurality of slits 6 ..., the resistance acting on the cutting tape 101 can be alleviated when the opening is performed, and the cutting of the cutting tape 101 can be prevented. In the packaging material 1 for rice processed food of the present embodiment, as shown in Fig. 14 and Fig. 15, in the state in which the rice processed food is packaged, at least one portion of the surface of the outer film 10 is adhered to the seal. 30, 35. The seals 30 and 50 can be suitably selected for displaying the predetermined information (the type of the content of the rice processed food, the order of opening the seal, etc.) in accordance with the portion to be adhered, and the person who has a plain design or a design pattern is used. The seals 30 and 35 may be formed in various forms such as a square shape, a circular shape, a triangular shape, a star shape, and a diamond shape. That is, the seals 30 and 3 5 can be set to an appropriate shape depending on the application, the position to be adhered, and the like. The seals 30, 35 are provided with a plurality of incisions 31 at the peripheral portion. . -26-201033094 36. By the fact that the cut marks 3 1···, 36··· can alleviate the impedance acting on the cutting tape 101 at the time of opening, and prevent the breakage of the cutting tape 101. That is, when the seal of the label or the like is attached in accordance with the arrangement of the lap tape 101, the presence of the seal may hinder the travel of the lap tape 101. However, the seals 30 and 35 of the present embodiment are provided with plural numbers at the peripheral portion. Cut marks 31..., 36·. Therefore, even if it is adhered in accordance with the arrangement of the lap tape 101, it can be easily cut during the travel of the lap tape 101. Thereby, the aforementioned seals 30, 35 can prevent Φ from breaking on the way when the cover tape 101 is opened. In addition, as shown in FIG. 14, the packaging material 1 for rice processed foods of the present embodiment is packaged with rice processed foods in the same manner as in the first embodiment, and the other end side in the longitudinal direction of the packaging material 1 for rice processed foods. One half overlaps one end side, and the overlapped portion is fixed to a portion of the rice processed food packaging material 1 located on the lower side thereof, and the above-described seal 30 is used for the fixing. Further, since the seal 30 is adhered to the back side of the package state, for example, information such as the date of manufacture and the price can be printed. Φ Further, as shown in Fig. 15, the seal 35 is adhered to the surface side of the packaging material 1 for rice processed food (the surface side of the outer film 1). Further, since the seal 35 is adhered to the front side of the package state, it is preferable to display the product name, the type of the contents of the rice processed food RF, and the unsealing method of the unsealing means 100. Further, the number of sheets to be attached to the front side of the seal 35 may be one or more, and the number of sheets may be set according to the type of display. Further, the seals 30 and 35 can be adhered by the operator's hand, or can be attached mechanically by using a labeling machine or the like. Thus, the production efficiency can be further improved. -27- 201033094 In the present embodiment, a seal 35 of a content or the like is printed and pasted. Therefore, it is not necessary to use the packaging material 1 for rice processed food which is displayed in accordance with the type of the contents of the rice processed food RF. In this way, the packaging material 1 for a rice-processed food can be used in a plurality of types, and the packaging material 1 for rice processed foods is not required to be stocked in advance, and the work required for management can be reduced. Further, since the packaging material 1 for rice-processed foods can be used continuously, even if the contents are changed, it is not necessary to change the process, and the productivity can be greatly improved. In the above description, the seal 35 showing the type of the contents of the rice processed food RF is adhered to the surface side of the outer film 10 of the rice processed food packaging material 1, but for the common portion (for example, the design pattern) Part or the like can also be carried out by printing such as gravure printing as in the related art. Next, a packaging material for rice processed food according to a fifth embodiment of the present invention will be described with reference to Figs. 16 to 19 . Fig. 16 is a schematic inside view showing the interior side of the rice processing food packaging material, and Fig. 17 is a schematic top view showing the exterior side of the rice processed food packaging material 1. Fig. 18 is an explanatory view of a packaging material for rice processed food, wherein (a) is a perspective view showing a state in which rice processed food is packaged, and (b) is a perspective view at the time of opening. Figure 19 is a perspective view after opening. In addition, as shown in the respective drawings, the basic structure of the packaging material for rice processed food of the present embodiment is common to the packaging materials for rice processed foods of the first to fourth embodiments, and therefore, the first to fourth embodiments are implemented. The description of the parts in common is omitted, and the different structures are mainly described. In addition, for the convenience of description, the structures of the package materials for rice processed foods according to the first to fourth embodiments are the same or equivalent, and -28-201033094 is given the same names as the structures of the first to fourth embodiments, and Give the same symbol. As shown in Figs. 16 and 17 , the unsealing means 100 of the present embodiment includes at least two cutting tapes 101a and 101b which are attached to at least two of the outer film 10 so as to extend in the longitudinal direction. Further, in the opening and closing section 1 of the present embodiment, in addition to the cutting tapes 101a > l〇lb, the slits 102 and 102 are provided in the same manner as in the first to fourth embodiments. The two Φ strips 101a and 101b are disposed to intersect each other with at least one portion of the outer film 10 in the longitudinal direction. In the present embodiment, the two cutting tapes 10a and 101b are disposed so as to intersect each other in the vicinity of the picking portion 103 formed by the slits 102 and 102 on the one end side in the longitudinal direction of the outer film 10. After the intersection portion C1), the other end side in the longitudinal direction of the packaging material 1 for rice processed food is gradually drawn away from the arc, and is closer to the other end than the center in the longitudinal direction of the packaging material 1 for processed rice food. The side portion is gradually approached and intersected again (the second intersecting portion C2) while drawing the arc, and then gradually draws away from the arc on the other end side. In other words, the two sinusoidal strips 101a and 101b are in a state in which the mutual mountain portions and the valley portions are opposed to each other via the intersecting portions C1 and C2. Therefore, it is possible to form an opening having a width which is substantially the same as the maximum distance formed by the top position of the mountain portion of the rain cutting belt 10a, 101b and the deepest portion of the valley portion, in the packaged food for rice processed food. The outer film 10 of 1. The packaging material 1 for rice processed food of the present embodiment is composed of the above structure, and the rice processing -29-201033094 is packaged in the same manner as in the first to fourth embodiments. When the rice processed food RF is taken out and eaten, as shown in Fig. 18 (a), first, the picking portion 103 is grasped and pulled forward, and the outer film 10 is cut by the tapes 10a, 101b. Cut in the longitudinal direction. Furthermore, the seal 30 which cuts the seal 30 and the packaging material 1 for rice processed foods by the two strips 101 is adhered to the strip 101 which is located at the lower end and overlaps (part of the strip 101) It is integrated into the vicinity of the intersection C2. As a result, as described above, when the outer film 0 10 is cut in the longitudinal direction by the cutting tapes 10a, 101b, as shown in FIG. 18(b), the two strips 101 are to be cut. The dispersed tensile force is temporarily concentrated on a portion (P) of the seal 30 when the seal 30 is cut, so that the rice processed food package 1 and the seal 30 are cut together. In addition, as described above, the cutting tape 101 is formed by one of the intersection portions C1 and C2, and the portion of the rice processed food packaging material 1 and the strip 30 are further pulled apart, and then cut off again. In the rice processed food packaging material 1, as shown in Fig. 19, an opening having a wider width than the width of the tape cassette 101 itself is formed in the rice processed food packaging material 1. Then, when the rice processed food packaging material 1 divided in the width direction is pulled away from the direction (arrow E), the packaging materials are removed, and the rice processed food RF wound with the flaky food SF is exposed. In the present embodiment, by forming the opening having a wider width than the width of the tapes 10a and 101b, the coated area of the rice processed food package 1 can be made smaller than the rice processed food RF. In the same manner, the frictional resistance to the rice processed food RF at the time of drawing the packaging material 1 for rice processed food which has been divided by -30-201033094 is reduced, and the residual processed rice can be smoothly removed. Packaging material 1. Therefore, the packaging material for rice processed food of the present embodiment has an advantage that it is easy to take out the rice processed food RF instantaneously. In addition, the packaging material for rice processed food of the present invention is not limited to the above-described respective embodiments, and various modifications can be made without departing from the scope of the technical idea of the present invention. That is, the material of the outer film 10 and the inner film 20 is not particularly limited. For example, a general-purpose film made of polypropylene or polyethylene can be used. Further, the inner film 20 (the pair of films 20a and 20b) is preferably a polyethylene having a good separation effect from the rice processed food RF, but the moisture is not passed through and is separated from the rice processed food RF. The effect is good. In addition, in each of the above embodiments, the triangular shaped rice processed food RF is targeted, but the present invention is not limited thereto, and for example, rice processed food processed into a cylindrical shape may be used. Further, in each of the above embodiments, the notch portion 160 is formed at the four corner portions of the outer film 10 and the inner film 20. However, the outer film 10 and the inner film 20 may be formed at two corner portions adjacent to each other in the width direction. Further, in each of the above embodiments, the cutting tapes 101, 101a, and 101b are used as one configuration of the unsealing means 100. However, the unsealing means 100 is not limited thereto, and for example, a tear line extending in the longitudinal direction of the outer film 10 may be used. The opening means 100 is formed in the width direction in pairs at intervals. Thereby, since the outer film 10 can be cut by the pair of two tearing lines, the -31 - 201033094 can cut the tear line into a strip shape, and the cutting tape 101, l〇la, 101b Similarly, the outer film 10 can be cut. In particular, in the case where the outer film 10 is formed of an extended film, the opening means 100 may not be provided with the cutting tape 101, but only one of the ends of at least one of the both ends of the outer film 10 in the longitudinal direction. The slits 102 and 102 are formed. For example, the outer film 10 is formed by a uniaxially stretched film, or a biaxially stretched film, or a laminate of a uniaxially stretched film and an unaligned film, or a laminate of a biaxially stretched film and an unaligned film. In other words, even if the cutting tape 101 is not provided, only the picking portion 103 formed between the slits 102 and 102 can be grasped, and the outer film 10 can be cut in the longitudinal direction with the width between the slits 102 and 102. Therefore, it is possible to maintain the ease of opening. Further, in the case where the stretched film is used for the outer film 10, contrary to the above, the unsealing means 100 may be formed only by the cut tape 101 without providing the slits 102, 102. In each of the above embodiments, the notch portion 160 defined by the straight portion 1 60a and the inclined portion 160b is used. However, the notch portion 160 is not limited to this shape, and may be, for example, a linear or slightly arc-shaped end edge. (Edge) with 10 delimiters. Further, as shown in FIG. 20, the one end 6a (and/or the other end 6b) of the rice processed food packaging material 1 may be extended toward the one end 6c (and/or the other end 6b) in the width direction. The notched portion 160 is defined by the serrated edge 9e. Further, the edge 9e may be formed as a line passing through a straight line or a slightly arc shape (not shown). In each of the above embodiments, the overlapping portion of the first inner film 20a and the second inner film 20b constituting the inner film 20 (the overlapping portion of the central portion in the width direction of the outer film 1A) is in a non-adhesive manner. However, the present invention is not limited thereto, and for example, the overlapping portion of the first inner film 20a and the second inner film 20b may be weakly sealed by peeling. The weak seal may be partially formed in a plurality of portions spaced apart from each other in the longitudinal direction by the first inner film 20a and the second inner film 20b, or may be formed in a continuous line shape along the longitudinal direction. Further, in the above embodiments, the outer peripheral end portion of the outer film 10 and the outer peripheral end portion of the inner film 20 are intermittently thermally heated. However, the outer peripheral end portion of the outer film 10 and the inner film 20 may be not limited thereto. The peripheral end portion # is continuously heated. In the above embodiments, the inner film 20 is formed of the first inner film 20a and the second inner film 20b. However, the inner film 20 may be formed of a single film in the same manner as the outer film 1?. In this case, as a means for separating the inner film 20, a tear line or a half cut may be formed. In each of the above-described embodiments, the overlapping portion (the third portion 4 and the fourth portion 5) of the packaging material 1 for rice processed foods in which the rice processed food RF is packaged (in a form corresponding to the rice processed food RF) is packaged. ® adheres the seal 30 to maintain the packaging state of the rice processed food RF, but is not limited thereto. For example, as shown in Fig. 21, the bent (packaged) rice processed food is used in order to correspond to the form of the rice processed food RF. The three corner portions El, E2, and E3 formed by the packaging material 1 are sealed in a strip shape (heat sealing), and the corner portions E1, E2, and E3 may be sealed. In this case, the overlapping portion (the third portion 4 and the fourth portion 5) of the packaging material 1 for processed rice food is also adhered to the seal 30, so that the packaging of the rice processed food RF can be confirmed. In the above-described second to fifth embodiments, the other end side in the width direction of at least one of the first inner film 20a and the second inner film 20b which constitutes the inner film 20-33-201033094 is folded, but is not limited thereto. For example, it may be configured in the same manner as in the first embodiment. In addition, the inner film 20 of the packaging material for rice processed food of the first embodiment can be in the form of the second to fifth embodiments. That is, the inner film 20 may be in any one of the first embodiment to the fifth embodiment. In the fifth embodiment, the two cutting tapes 101a and 101b are disposed so as to intersect each other at least at a portion of the outer film 10 in the longitudinal direction. However, the two cutting tapes 101a and 101b are not necessarily required. cross. For example, the two strips are not placed, and each of them is placed in a wave shape and then placed on the outer film 10, or the two strips are not crossed, and each of them is linearly arranged and placed on the outer film 10.
