132^665 (1) 九、發明說明 【發明所屬之技術領域】 本發明是關於包裝具，特別是關於供集合包裝複數個 圓筒狀的容器用之包裝具。 【先前技術】 過去以來，供集合包裝複數個收納有淸涼飮料、啤酒 φ 或是酒類等的飮料之圓筒狀的容器用之包裝具已有種種的 記載。例如，以「罐用複合包」的名稱，用板狀的紙箱材 作成立方體形狀，將6罐的容器收納在其中（例如，參考 曰本專利文獻1)。在此罐用複合包，從上板切入側板的 上部而形成有帶狀的把手。藉由抓住此帶狀的把手，很容 易就將收容有罐容器的複合包提起。 不過，單是切入上板和側板的上部而形成把手的情況 ，會有以下的問題。即是罐容器無間隙地收納在複合包內 φ 的情況，構成複合包之紙箱材不變形，手伸入到把手會有 困難的問題。此外，也會有爲了增高變形性，而在複合包 與罐容器之間設置很大的間隙，則罐容器偏離複合包，有 時就會脫離複合包的問題。 能解決上述的問題之包裝用捆包具也有記載。如第6 圖和第7圖所示，此包裝用捆包具101係爲了形成握持部 125而設置二條騎縫線124，在這兩騎縫線124之間形成 另外的騎縫線130(例如，參考日本專利文獻2)。另外 的騎縫線130形成在與所收容之罐的上端緣相對應的位置 -4- ' (2) 132泛665 上。因而，提起握持部125，包裝用捆包具ιοί 會接近到罐的上端側，騎縫線1 3 0張開而罐的上 . 進入。因此，包裝用捆包具101形成爲很容易就 此結果是形成爲能夠用力向上方提起握持部125< 再則，形成有將包裝對象物也就是將瓶子等 • 住之孔208之包裝用捆包具也有記載（例如，參 利文獻）。此包裝用捆包具如第8圖所示，在與 φ 部相對應的位置形成反三角形狀的孔208，瓶子 入到該孔208中就會抑制瓶子的偏移或移動。 〈日本專利文獻1> 特開2001— 328670號 2圖，摘要） <日本專利文獻2> 特開平8 — 25 5 1號公 圖，摘要） <曰本專利文獻3> 實開平7-115 66號公 圖） 【發明內容】 <發明所欲解決之課題> 不過，上述日本專利文獻2的包裝用捆包具 • 下的問題。即是形成在握持部1 25之間的騎縫線 ，因而握持部125向上方提起時，罐的上端緣立 騎縫線130的兩端。然且，在罐的上端緣，一般 成上蓋的一部分之環狀的突起，因而此突起咬入 130的兩端部而對各端部施加很大的應力；有時 的上端就 端緣就會 能變形。 的頭部卡 考曰本專 瓶子的頭 的頭部嵌 公報（第 報（第3 報（第1 還會有以 1 3 0很短 即接觸到 形成有構 到騎縫線 會有騎縫 -5- (4) 1326665 4 面部' 側面部、以及底面部，由前述上面部往 有2條的裁切線而形成握持部，在前述各裁切 就是在前述上面部與各側面部的交界領域’設 的寬度和高度之開口部，以前述握持部向上拉 口部接近到容器上端部側的情況，前述開口部 到容器的外周面比開口部的寬度方向兩端接觸 上端部還先的方式來形成前述開口部。 p 這種構成的情況’即使提起握持部’很大 會施加到開口部的兩端。因而’能有效防止開 破裂。 另外，本發明的申請專利範圍第2項，其 口部的寬度爲即使前述握持部向上拉起而前述 到容器上端部側的情況，前述容器上端部仍不 述開口部的寬度方向兩端之寬度。以這種構成 明的申請專利範圍第1項的作用，力量不會從 φ 直接施加到開口部兩端，因而更加防止包裝具〖 本發明的申請專利範圍第3項，其中：前 有反三角形的形狀。以這種構成，加上本發明 範圍第1或2項的作用，開口部之三角形的二 器的外周面而以此部分來均等承受外力。因而 口部的各頂點之應力減低。 本發明的申請專利範圍第4項，其中：前 的與前述容器的外周面相接觸的部分形成爲圓 種構成，加上本發明的申請專利範圍第1或2 各側面部設 線之間，也 有具有預定 起而前述開 的下緣接觸 到前述容器 的應力仍不 口部兩端的 中：前述開 開口部接近 會接觸到前 ，加上本發 容器上端部 θ破裂。 述開口部具 的申請專手IJ 邊接觸到@ ，施加到_ 述開口部中 弧狀。以逭 項的作用， 1326665 ' (5) 以開口部的圓弧狀緣部來與容器的外周面均等接觸，所以 即使從握持部施加很大的力量，仍能以圓弧狀緣部來均等 . 承受此力量。此結果是·有效抑制包裝具的破裂。 本發明的申請專利範圍第5項，其中：相當於前述開 口部的頂點之部分形成爲圓弧狀。以這種構成，加上本發 明的申請專利範圍第1 ~4項的作用，即使應力施加到開口 部的各頂點’與如同過去之線狀的開口部作比較，應力不 φ 易集中在一處，而更加抑制包裝具的破裂。 再則，本發明的申請專利範圍第6項，其中：在前述 開口部之寬度方向的兩側近旁’設有與前述上面部和側面 部的交界線相交叉之裁切線。以這種構成，加上本發明的 申請專利·範圍第1〜5項的作用，即使如果包裝具從開口部 的兩端開始破裂的情況，破裂會在該裁切線停止，而抑制 破裂繼續前進。 φ 【實施方式】 參照附圖詳細說明本發明的一個實施形態。 <全體槪要> 第1圖爲本實施形態之包裝具1的展開圖。如該第1 圖所示，包裝具1係由上面部1A、及連接到此上面部ία 的兩側之側面部1 B !和1 B2、及還連接到各側面部1 B i和 1B2之底面部lCi和1C2相互間成一體所構成。各構件1A 、ΙΒι、IB2、ICi、1C2由薄紙製的材料所組成，以上面部 '側面部以及底面部的交界線來相互彎摺。然而，材料也 -8- (6) 1326665 可以用有預定的厚度之紙箱材等。另外，包裝具1的寬度 W係依據罐容器的大小進行種種的選擇，不過本實施形態 約爲175 mm。另外，上面部的LA約爲125 mm，各側面 部 ΙΒι ' 1B2 的 LB!、LB2 約爲 170 mm。 另外，在側面部IBt'lBa之寬度方向的兩端，形成 有爲了使包裝容器（例如，罐容器）的時候，容器不致於 滑落之阻止部3。另外，2個的底面部1C!、1C2係藉由 g 相互結合，而形成爲與上面部1A同樣的大約125 mm所 構成。底面部1(^、1(：2彼此間的結合係將形成在另一方 的底面部1C2之突起部7卡合到形成在其中一方的底面部 1 C !之承孔5中。再則，也有用黏著劑將兩者接合來進行 結合的情形。然而，圖中的虛線是表示彎摺線。 包裝到本實施形態的包裝具1中爲圓筒狀的罐容器， 高度約爲17〇 mm，罐身部分的外周直徑約爲66 mm，設 成倒角之上端部的直徑約爲60 mm (2又6/16英吋）。 φ 另外，其重量則每一個約爲500 g程度。因而，如後述包 裝有6罐的罐容器的情況，全重量約成爲3 000 g。只不過 這些的尺寸及重量只是一個例子而已。罐容器各部的尺寸 若有變化，隨著此變化而包裝具1各部的尺寸也跟著變更 。另外，所要包裝的對象物並不侷限於罐容器，若爲圓筒 狀的容器，則裝有食品的罐等任何的罐都能對應。 <裁切線及握持部> 在上面部1A，設有用來形成握持部11之有預定的彎 (7) 132,6665 曲形狀之2條的裁切線13。各裁切線13是以相互對稱的 方式所形成，各裁切線13的端部到達側面部IBi、1B2的 一部分爲止。以各裁切線13所夾入的領域13之寬度係中 央部寬闊，面對各側面部1 B !、1 B2的方向則一度變窄。 然後，面對與側面部1B!、1B2的交界領域又再度變寬， 而此部分成爲所謂的八字形狀。另外，在於側面部lBj、 1B2也同樣成爲八字形狀。此處，以2條裁切線13所夾入 φ 之領域的寬度最窄的部分存在於上面部1A，其寬度例如 爲30 mm。只不過此値只是一個例子而已，即使爲20 mm 或是40 mm皆可，還可以是這兩値之間的値。 此外，上面部1A之中央的寬度較寬的部分成爲約72 mm的寬度。然後，此寬度較寬的部分以分別形成大致三 角形的方式形成有預定的彎折線15。具體上，三角形的一 邊爲朝包裝具1的寬度方向成直角，其餘的二邊則是與寬 度方向相對成3 0度程度傾斜。然後，朝相對寬度方向而 φ 往直角的方向延伸之2條彎折線1 5彼此間的間隔係與上 述過寬度的最窄部分30 mm同等。再則，上面部1A與側 面部IB!、1B2的交界線上之2條裁切'線13的間隔約成爲 110mm。 另外，本實施形態的裁切線13並不是把全長都完全 裁斷，而是仍有斷續接合之不連續的裁切線13。此理由是 防止在使用握持部之前就突出握持部11會妨礙到搬運之 故。只不過當然也可以是一開始就完全裁斷全體之連續的 裁切線。再則，到達各裁切線1 3的側面部1 B i、1 B2之各 -10- (8) 1326665 端部爲朝向包裝具1之寬度方向的內側之大致圓弧形狀部 1 9。此理由是如後述，即使很大的負荷施加到握持部1 i， 包裝具1也不會在於裁斷線13的端部破裂之故。」 <開口部> 其次，針對形成在2條裁切線1 3的相互間，也就是 形成在上面部1 A與側面部1B!、1B2之間的交界領域之開 | 口部21作說明。此開口部21爲在已包裝有罐容器的時候 ，罐容器的上端部接近或是接觸。具體上是形成爲握持部 1 1向上拉起而開口部21接近到容器上端部側的情況，開 口部的下$ 2 1 a接觸到容器的外側面比開口部2 1的寬& 方向兩端接觸到容器上端部還先。如第1圖所示，開口部 21具有大致三角形狀，2個頂點位於上面部1A與側面部 1B!、1B2之交界線的近旁，其餘的頂點位於側面部1Bl、 1B2。因而，組合該包裝具1時，開口部21的各頂點23 φ 成預定的圓弧狀切穿。這理由是使包裝具1不會在於該頂 點23破裂之麥。然而，此開口部21係由接近到容器上端 部側之大、至/四角形狀的部分、及接觸到容器的外周面之大 至;三角形的部分所構成。 開口部2 1的寬度Wo能依據所包裝罐容器的大小進 行種種的選擇，不過本實施形態則是約爲51 mm。因此， 考慮到與上述罐容器的上端部的直徑約爲60 mm之關係， 則成立開口部寬度Wo :上端部直徑与5 : 6的關係。設定 開口部寬度與容器上端部直徑的比來使這樣的關係成立， -11 - (9) I32t6665 容器上端部就不會接觸到開口部2 1的寬度方向兩端，經 實驗已得到證明。另外，開口部21的高度（圖中的上下 方向）Lo約爲21 mm。然而，這些的値只是一個例子而已 ，開口部寬度Wo也可以是40 mm〜60 mm程度，高度Lo 也可以是10 mm~30 mm程度。 另外，在開口部21之寬度方向的兩端近旁，由開口 部2 1有些許的隔離而分別形成有裁切線（圓弧狀裁切線 φ ) 25。此圓弧狀裁切線25往沿著開口部21的兩端的圓弧 之方向（面對寬度方向外側之凸的圓弧）彎曲。此圓弧狀 裁切線25能有種種的選擇，不過本實施形態則是跨過上 面部1A與側面部IB!、1B2的交界線而成約爲10 mm程 度。 <作用> 其次，參照第2圖〜第4圖說明本實施形態之包裝具1 φ 的作用。第2圖爲表示用本實施形態的包裝具1包裝6罐 的罐谷器的情況之平面圖及正面圖。此圖則是表不运沒向 上拉起握持部11的狀態。如第2(A)圖的平面圖所示， 罐容器是每2罐排列成3列來包裝，在與中央的2罐相對 應的位置形成有握持部11。另外，如平面圖和正面圖所示 ，包裝具1的開口部21位於與中央的罐容器之上端部相 對應的位置。但是，如同圖中未向上拉起握持部11的狀 態則是罐容器的上端部沒有接觸到開口部21的各緣部。 其次，第3圖爲第2(B)圖的III— in線之剖面圖， -12- 1326665 * (10) 特別是表示握持部11向上拉起的狀態之圖β爲了向上拉 起握持部11，而將往握持部11的中央部之兩外側彎曲的 • 部分往包裝具1的內側彎摺。此時，在彎曲著的部分形成 有二角形狀的彎折線1 5，所以沿著此彎折線1 5彎摺握持 部1 1的一部分，並容易進入到罐容器彼此間的間隙。然 •後’把手指插入到握持部11的下面來握持握持部U，故 能夠向上拉起握持部11。向上拉起握持部11，則隨著動 φ 作而包裝具1的上端部就會朝握持部11的中心方向靠近 。因而，形成在包裝具1的開口部21接近到罐容器的上 端緣。 不過，開口部21的寬度Wo形成比過去的還長，所 以開口部21的下緣21a接觸到容器的外周面比開口部21 的兩端接觸到容器的上端緣還先。這點從第4圖中的擴大 開口部21的周邊之立體圖就能明白。因此，在開口部21 的兩端部不會集中應力，此部分就不會破裂。如果，即使 φ 施加預料外很大力量而開口部21的兩端破裂的情況，上 述圓弧狀裁切線25形成在兩側近旁，所以破裂就會在此 圓弧狀裁切線25停止，而抑制繼續前進。 此外，如同上述過開口部21的2條下緣21a隨著握 ' 持部Π向上拉起就接觸到罐容器的外周面。此時，開口 部21藉由2條的下緣21a而成爲反三角形狀，所以在於 各下緣21a較長的範圍接觸到罐容器的外周面。因而’不 會局部對各下緣21a施加過大的應力；另外，下緣21a爲 直線，所以包裝具1也不會從該下緣21a開始破裂然而 -13- (11) 1326665 ’也可以取代該2條下緣21a，改而將開口部21的下緣全 體形成爲凹入下方的圓弧狀。如此，將罐容器的外周面所 接觸之開口部21的下緣設成圓弧狀，就能夠更均等與罐 容器接觸’又能夠有效防止包裝具的破裂。另外’此開口 部21也可以由與容器上端部側接近之大之四角形狀的部 分、及與容器的外周面接觸之大致圓弧狀的部分所形成（ 參考第5 ( B )圖）。 | 另外，如同上述過，本實施形態的包裝具則也有推定 爲開口部21的寬度方向兩端接觸到容器上端部的情況， 不過也能設定爲又考慮到容器的尺寸或包裝具的材料強度 ’而開口部21的兩端又不會接觸到容器上端部。 另外，如同上述過，直到達到側面部1 B! ' 1B2爲止 之裁切線1 3的端部係以面對包裝具1的中心側之半圓弧 形狀部19所形成。如此，將裁斷線13的端部朝向中心側 的情況，即使很大的力量施加到握持部1 1，包裝具1也不 φ 容易在於裁斷線13的端部破裂。 〔產業上利用的可能性〕 本發明爲用紙等的材料所製造之包裝具，也就是可適 用於集合複數罐有重量的罐容器等來包裝之包裝具等。 〔發明之效果〕 本發明的包裝具，在包裝具的上端部形成有寬度較寬 的開口部，所以開口部的下緣部接觸到容器的外周面比容 -14- (12) (12)1326665 器的上端部接觸到開口部的兩端還先；以此下緣來承受力 量，所以能有效防止開口部兩端造成破裂。 【圖式簡單說明】 第1圖爲表示本發明的一個實施形態之包裝具的展開 圖。 第2圖爲表示組裝第1圖所圖式的包裝具的狀態之圖 ，桌2(A)圖爲表不平面圖，第2(B)圖爲表不正面圖 〇 第3圖爲第2 ( B )圖的III — III線之剖面圖；特別是 表示提起握持部的狀態。 第4圖爲第2圖所圖示的包裝具之立體圖；特別是表 示提起握持部的狀態。 第5圖爲本發明之包裝具的開口部的變形例之立體圖 :第5(A)圖爲把四角形狀和三角形狀組合起來的情況 ，第5(B)圖爲把四角形狀和圓弧狀組合起來的情況。 第6圖爲表示過去的包裝具之正面圖。 第7圖爲第6圖所圖示的包裝具之立體圖^ 第8圖爲表示其他的過去例子之立體圖。 【主要元件符號說明】 I :包裝具 II :握持部 13 :裁斷線 -15- (13)1326665 2 1 :開口部 2 1 a :下緣 25:裁斷線（圓弧狀裁斷線） 1 A :上面部 1 B !、1 B 2 :側面部 1 C 1、1 C2 :底面部132^665 (1) Description of the Invention [Technical Field of the Invention] The present invention relates to a package, and more particularly to a package for packaging a plurality of cylindrical containers. [Prior Art] In the past, there have been various types of packaging materials for cylindrical containers for collecting and packaging a plurality of packets containing buckwheat, beer φ or alcohol. For example, a 6-can container is housed in a cubic shape by a plate-shaped carton material under the name of the "composite package for cans" (for example, refer to Patent Document 1). In this can composite bag, a strip-shaped handle is formed by cutting the upper portion of the side plate from the upper plate. By grasping the belt-shaped handle, it is easy to lift the composite bag containing the can container. However, the case where the handle is formed by cutting the upper portion of the upper plate and the side plate alone has the following problems. That is, when the can container is accommodated in the composite bag φ without a gap, the carton constituting the composite bag is not deformed, and it is difficult to reach into the handle by hand. In addition, in order to increase the deformability, a large gap is provided between the composite bag and the can container, and the can container deviates from the composite bag, and sometimes the problem of the composite package is removed. The packaging package for solving the above problems is also described. As shown in FIGS. 6 and 7, the packaging harness 101 is provided with two riding stitches 124 for forming the grip portion 125, and an additional riding stitch 130 is formed between the two riding stitches 124 (for example, reference) Japanese Patent Document 2). The additional riding stitch 130 is formed at a position -4- ' (2) 132 pan 665 corresponding to the upper end edge of the contained can. Thus, the grip portion 125 is lifted, and the package bundle ιοί is brought close to the upper end side of the can, and the sling line 1130 is opened and the can is inserted. Therefore, the packaging package 101 is formed so that the grip portion 125 can be lifted upwards with force, and a packaging bundle for the packaging object, that is, the hole 208 for holding the bottle or the like, is formed. The package is also documented (for example, the reference document). The packaging package has an anti-triangular hole 208 at a position corresponding to the φ portion as shown in Fig. 8, and the bottle is inserted into the hole 208 to suppress the offset or movement of the bottle. <Patent Document 1> JP-A-2001-328670, 2, and Abstract) <Japanese Patent Literature 2> Japanese Patent Laid-Open No. Hei No. Hei 8-2551, Abstract) <曰本专利文件3> 实开平7-115 [Patent No. 66] [Problem to be Solved by the Invention] The problem of the packaging package of the above-mentioned Japanese Patent Document 2 is a problem. That is, the sacrificial line formed between the grip portions 125, and thus the upper end edge of the can is erected at both ends of the suture line 130 when the grip portion 125 is lifted upward. However, at the upper end edge of the can, it is generally an annular protrusion of a part of the upper cover, so that the protrusion bites into both ends of the 130 and exerts a great stress on each end; sometimes the upper end will be at the end edge. Can be deformed. The head of the card is the head of the special bottle of the head of the bullet-inlaid bulletin (the third report (the first one will have a short distance of 1 3 0, that is, the contact with the formation of the riding line will have a seam -5 - (4) 1326665 4 The side surface portion and the bottom surface portion of the face portion are formed by two cutting lines from the upper surface portion, and the respective cutting portions are provided at the boundary between the upper surface portion and each of the side surface portions. The opening portion of the width and the height is such that the grip portion comes close to the upper end portion of the container, and the opening portion reaches the outer peripheral surface of the container in a manner in which the both ends in the width direction of the opening portion contact the upper end portion. The above-described opening portion is formed. p In the case of such a configuration, even if the lifted grip portion is large, it is applied to both ends of the opening portion. Therefore, it is possible to effectively prevent cracking. Further, the second aspect of the patent application of the present invention is The width of the portion is such that the above-mentioned grip portion is pulled up to the upper end side of the container, and the upper end portion of the container does not describe the width of both ends in the width direction of the opening portion. Item The force is not directly applied from both φ to the both ends of the opening portion, thereby further preventing the packaging member from the third aspect of the patent application scope of the present invention, wherein: the shape of the anti-triangle is preceded. With this configuration, the scope of the present invention is added. The action of the first or second term, the outer peripheral surface of the two triangular members of the opening portion, and the external force is equally received by the portion. Therefore, the stress at each vertex of the mouth portion is reduced. The fourth aspect of the patent application of the present invention, wherein: The portion in contact with the outer peripheral surface of the container is formed in a circular shape, and between the side portions of the first or second side portions of the patent application range of the present invention, there is also a predetermined lower edge and the lower edge of the opening is in contact with the container. The stress is still not in the middle of the two ends of the mouth: the opening portion is close to the front, and the upper end portion θ of the hair container is broken. The application of the opening member IJ is in contact with @ and is applied to the opening portion. It has an arc shape. It acts as a , item, 1326665 ' (5) The arcuate edge of the opening is in equal contact with the outer peripheral surface of the container, so even if a large force is applied from the grip, The arc-shaped edge portion is equalized. The force is received. The result is that the rupture of the packaging tool is effectively suppressed. In the fifth aspect of the invention, the portion corresponding to the apex of the opening portion is formed in an arc shape. With this configuration, in addition to the effects of the first to fourth aspects of the patent application of the present invention, even if stress is applied to the apexes of the opening portion, the stress is not concentrated in one place as compared with the line-like opening portion in the past. Further, the rupture of the packaging tool is further suppressed. Further, in the sixth aspect of the invention, in the vicinity of the both sides in the width direction of the opening portion, the intersection of the upper surface portion and the side surface portion is provided. With such a configuration, in addition to the effects of the first to fifth aspects of the patent application of the present invention, even if the package is broken from both ends of the opening, the rupture stops at the cutting line. Suppress the rupture and move on. φ [Embodiment] An embodiment of the present invention will be described in detail with reference to the drawings. <All of the Summary> Fig. 1 is a development view of the packaging device 1 of the present embodiment. As shown in Fig. 1, the package 1 is composed of an upper surface portion 1A, side portions 1 B and 1 B2 connected to both sides of the upper surface ία, and also connected to the side surface portions 1 B i and 1B2. The bottom surface portions 1Ci and 1C2 are integrally formed with each other. Each of the members 1A, ΙΒι, IB2, ICI, and 1C2 is made of a material made of a thin paper, and the boundary line between the side surface portion and the bottom surface portion of the upper surface is bent. However, the material -8-(6) 1326665 can be used in a carton material having a predetermined thickness or the like. Further, the width W of the packaging material 1 is variously selected depending on the size of the can container, but this embodiment is about 175 mm. In addition, the LA of the upper surface is about 125 mm, and the LB! and LB2 of each side portion ΙΒι ' 1B2 are about 170 mm. Further, at both ends in the width direction of the side surface portion IBt'1Ba, a stopper portion 3 for preventing the container from slipping when the packaging container (for example, a can container) is formed is formed. Further, the two bottom surface portions 1C! and 1C2 are formed by being coupled to each other by g, and are formed to be approximately 125 mm similar to the upper surface portion 1A. The bottom portion 1 (1, 1 (the combination of 2 and 2) is formed by the protrusion portion 7 formed on the other bottom portion 1C2 in the through hole 5 formed in one of the bottom portions 1 C! It is also possible to use a bonding agent to join the two to form a bonding. However, the broken line in the figure indicates a bending line. The packaging container 1 of the present embodiment is a cylindrical can container having a height of about 17 mm. The outer diameter of the body portion is about 66 mm, and the diameter of the upper end of the chamfer is about 60 mm (2 and 6/16 inches). φ In addition, the weight is about 500 g each. In the case where a can of 6 cans is packaged as described later, the total weight is about 3 000 g. However, the size and weight of these are only an example. If the size of each part of the can is changed, the parts of the package 1 are changed with this change. In addition, the object to be packaged is not limited to the can container, and if it is a cylindrical container, any can or the like containing a food can correspond. <Cutting line and grip > In the upper face portion 1A, there is a predetermined order for forming the grip portion 11 Curves (7) 132, 6665 Curved lines 13 of two curved shapes. Each of the cutting lines 13 is formed symmetrically, and the end portions of the respective cutting lines 13 reach a part of the side surface portions IBi and 1B2. The width of the field 13 sandwiched by the cutting line 13 is wide at the center, and the direction of each side portion 1 B !, 1 B2 is once narrowed. Then, the boundary area with the side portions 1B! and 1B2 is again closed. In this case, the side portions 1Bj and 1B2 also have a splayed shape. Here, the narrowest portion of the field in which φ is sandwiched by the two cutting lines 13 exists on the surface. The width of the portion 1A is, for example, 30 mm. However, this is only an example, and even if it is 20 mm or 40 mm, it may be a flaw between the two turns. Further, the width of the center of the upper face 1A The wider portion has a width of about 72 mm. Then, the wider portion is formed with a predetermined bending line 15 in a manner of forming a substantially triangular shape, respectively. Specifically, one side of the triangle is at a right angle toward the width direction of the package 1. The remaining two sides are wide and wide The degree of inclination is inclined to about 30 degrees. Then, the interval between the two bending lines 15 extending in the direction perpendicular to the width direction and φ in the direction perpendicular to the width is equal to 30 mm of the narrowest portion of the over-width. The interval between the two cut 'lines 13 on the boundary line between the upper surface portion 1A and the side surface portions IB! and 1B2 is approximately 110 mm. Further, the cutting line 13 of the present embodiment does not completely cut the entire length, but is still intermittent. The discontinuous cutting line 13 is joined. This reason is to prevent the grip portion 11 from being obstructed until the grip portion is used. However, it is of course possible to completely cut the entire continuous cutting line from the beginning. Further, the end portions of each of the side surface portions 1 B i and 1 B2 reaching the respective cutting lines 13 are -10- (8) 1326665 end portions which are substantially circular arc-shaped portions 1 9 facing the inner side in the width direction of the package 1 . The reason for this is that, as will be described later, even if a large load is applied to the grip portion 1 i, the package 1 does not break at the end portion of the cut wire 13 . <Opening Portion> Next, the opening portion 21 formed between the upper surface portion 1A and the side surface portions 1B! and 1B2 is formed between the two cutting lines 13 . The opening portion 21 is such that the upper end portion of the can container is close to or in contact when the can container is packaged. Specifically, the grip portion 1 1 is pulled up and the opening portion 21 approaches the upper end side of the container, and the lower side of the opening portion contacts the outer side surface of the container more than the width & direction of the opening portion 2 1 . Both ends are in contact with the upper end of the container. As shown in Fig. 1, the opening portion 21 has a substantially triangular shape, and two apexes are located in the vicinity of the boundary line between the upper surface portion 1A and the side surface portions 1B! and 1B2, and the other apexes are located on the side surface portions 1B1 and 1B2. Therefore, when the package 1 is combined, the apexes 23 φ of the opening 21 are cut into a predetermined arc shape. The reason for this is that the package 1 does not lie in the rupture of the apex 23 . However, this opening portion 21 is composed of a portion which is close to the upper end side of the container, a portion which is shaped to a square shape, and a portion which is in contact with the outer peripheral surface of the container; a triangular portion. The width Wo of the opening portion 2 1 can be variously selected depending on the size of the can container to be packaged, but in the present embodiment, it is about 51 mm. Therefore, in consideration of the relationship with the diameter of the upper end portion of the can container of about 60 mm, the opening width Wo is set such that the diameter of the upper end portion is 5:6. The ratio of the width of the opening to the diameter of the upper end of the container is set such that the relationship is established. -11 - (9) I32t6665 The upper end portion of the container does not contact the both ends in the width direction of the opening portion 2, and has been experimentally proven. Further, the height (the vertical direction in the drawing) Lo of the opening portion 21 is about 21 mm. However, these flaws are only an example. The width Wo of the opening portion may be about 40 mm to 60 mm, and the height Lo may be about 10 mm to 30 mm. Further, in the vicinity of both ends in the width direction of the opening portion 21, a cut line (arc-shaped cutting line φ) 25 is formed by the opening portion 2 1 to be slightly separated. This arc-shaped cutting line 25 is curved in a direction along an arc of the both ends of the opening 21 (a convex arc facing the outer side in the width direction). The arc-shaped cutting line 25 can be variously selected. However, in the present embodiment, it is about 10 mm across the boundary line between the upper surface portion 1A and the side surface portions IB! and 1B2. <Action> Next, the action of the package 1 φ of the present embodiment will be described with reference to Figs. 2 to 4 . Fig. 2 is a plan view and a front view showing a state in which six cans of cans are packaged by the packaging tool 1 of the present embodiment. This figure is a state in which the grip portion 11 is pulled up. As shown in the plan view of Fig. 2(A), the can container is packed in three rows and arranged in three rows, and the grip portion 11 is formed at a position corresponding to the two cans at the center. Further, as shown in plan view and front view, the opening portion 21 of the package 1 is located at a position corresponding to the upper end portion of the central can container. However, as in the state in which the grip portion 11 is not pulled up, the upper end portion of the can container does not contact the respective edge portions of the opening portion 21. Next, Fig. 3 is a sectional view of the III-in line of Fig. 2(B), -12- 1326665 * (10) particularly showing a state in which the grip portion 11 is pulled up. In the portion 11, the portion bent to the outside of the center portion of the grip portion 11 is bent toward the inner side of the package 1. At this time, a bent line 15 having a double-angle shape is formed in the bent portion, so that a part of the grip portion 1 1 is bent along the bent line 15 and easily enters the gap between the can containers. However, the finger is inserted into the lower surface of the grip portion 11 to grip the grip portion U, so that the grip portion 11 can be pulled up. When the grip portion 11 is pulled up, the upper end portion of the package 1 approaches the center of the grip portion 11 as the motion φ is made. Thus, the opening portion 21 formed in the package 1 approaches the upper end edge of the can container. However, the width Wo of the opening portion 21 is formed longer than in the past, so that the lower edge 21a of the opening portion 21 comes into contact with the outer peripheral surface of the container before the both ends of the opening portion 21 come into contact with the upper end edge of the container. This can be understood from the perspective view of the periphery of the enlarged opening portion 21 in Fig. 4. Therefore, stress is not concentrated at both end portions of the opening portion 21, and this portion is not broken. If the φ is applied with a large amount of force and the both ends of the opening 21 are broken, the arc-shaped cutting line 25 is formed on both sides, so that the rupture stops at the arc-shaped cutting line 25, and the suppression is suppressed. Keep going. Further, the two lower edges 21a of the over-opening portion 21 are in contact with the outer peripheral surface of the can container as the grip portion 拉 is pulled up. At this time, since the opening portion 21 has an inverted triangular shape by the two lower edges 21a, the lower edge 21a is in contact with the outer peripheral surface of the can container in a long range. Therefore, 'the excessive stress is not locally applied to each of the lower edges 21a; in addition, the lower edge 21a is a straight line, so the package 1 does not start to rupture from the lower edge 21a, but the 13-(11) 1326665' can also replace the The two lower edges 21a are formed such that the entire lower edge of the opening portion 21 is formed in an arc shape recessed downward. As a result, the lower edge of the opening portion 21 in contact with the outer peripheral surface of the can container is formed in an arc shape, so that it can be more uniformly contacted with the can container, and the breakage of the package can be effectively prevented. Further, the opening portion 21 may be formed by a portion having a large quadrangular shape close to the upper end side of the container and a substantially arc-shaped portion in contact with the outer peripheral surface of the container (refer to Fig. 5(B)). In the packaging tool of the present embodiment, it is estimated that both ends of the opening portion 21 in the width direction are in contact with the upper end portion of the container, but it is also possible to set the size of the container or the material strength of the package. 'The two ends of the opening portion 21 are not in contact with the upper end portion of the container. Further, as described above, the end portion of the cutting line 13 up to the side surface portion 1B! '1B2 is formed by the semicircular arc-shaped portion 19 facing the center side of the package 1. As described above, when the end portion of the cutting wire 13 is directed toward the center side, even if a large force is applied to the grip portion 1, the package 1 is not easily ruptured at the end portion of the cutting wire 13. [Industrial Applicability] The present invention is a packaging material manufactured from a material such as paper, that is, a packaging material which can be used for packaging a plurality of cans having a weight of a can container or the like. [Effects of the Invention] In the packaging device of the present invention, since the opening portion having a wide width is formed at the upper end portion of the packaging device, the lower edge portion of the opening portion contacts the outer peripheral surface of the container to a specific volume -14 - (12) (12) The upper end of the 1326665 is in contact with both ends of the opening; the lower edge is used to withstand the force, so that the ends of the opening can be effectively prevented from being broken.
