本実施形態のシート包装体100は、さらに蓋体50を有する。蓋体50は、開裂した天面11の一部BLで形成され、取出口20を再封可能に閉口する。ここで、取出口20を再封可能に閉口するとは、蓋体50が開口した取出口20(開口OP)を覆うことを示す(図9、図11)。
The sheet package 100 of the present embodiment further has a lid 50. The lid body 50 is formed of a part BL of the cleaved top surface 11, and closes the outlet 20 so that the outlet 20 can be resealed. Here, closing the outlet 20 so that it can be resealed means that the lid 50 covers the opened outlet 20 (opening OP) (FIGS. 9 and 11).
蓋体50は、端縁51が天面11に接続されている。ここで、端縁51が天面11に接続されるとは、取出口20(開口OP)が開口した後も蓋体50が端縁51を介して天面11に固定された固定端となることを示す(図9)。なお、蓋体50の端縁51は、本実施形態のシート包装体における蓋体の端縁の一部の一例である。
The edge 51 of the lid 50 is connected to the top surface 11. Here, when the edge 51 is connected to the top surface 11, the lid 50 is a fixed end fixed to the top surface 11 via the edge 51 even after the outlet 20 (opening OP) is opened. This is shown (Fig. 9). The edge 51 of the lid 50 is an example of a part of the edge of the lid in the sheet package of the present embodiment.
本実施形態のシート包装体100では、蓋体50に、加工部60が設けられている(図1、図3、図8)。加工部60は、蓋体50の閉口動作を遅延させる機能を有する。ここで、蓋体50の閉口動作を遅延させるとは、取出口20を開口する方向に蓋体50を展開したときに、蓋体50が取出口20を閉口する元の状態に戻ろうとする動きを遅くすることを示す。
In the sheet packaging body 100 of the present embodiment, the lid body 50 is provided with a processed portion 60 (FIGS. 1, FIG. 3, and FIG. 8). The processing unit 60 has a function of delaying the closing operation of the lid body 50. Here, delaying the closing operation of the lid 50 means that when the lid 50 is deployed in the direction of opening the outlet 20, the lid 50 tries to return to the original state of closing the outlet 20. Indicates to slow down.
なお、蓋体50が元の状態に戻ろうとする動きは、蓋体50に加わった外力により蓋体50の内部に生じる弾性応力(以下、応力という)による蓋体50の動きであると考えられる。そして、蓋体50の内部に生じた弾性応力分布が加工部60により不連続ないし部分的に緩和される(以下、蓋体の応力が緩和されるという)ことが、蓋体50の閉口動作が遅延する理由の一つと考えられる(図9、図10)。
It is considered that the movement of the lid body 50 to return to the original state is the movement of the lid body 50 due to the elastic stress (hereinafter referred to as stress) generated inside the lid body 50 due to the external force applied to the lid body 50. .. Then, the elastic stress distribution generated inside the lid 50 is discontinuously or partially relaxed by the processed portion 60 (hereinafter, the stress of the lid is relaxed), so that the closing operation of the lid 50 is performed. This is considered to be one of the reasons for the delay (Figs. 9 and 10).

なお、取出口20は、第1方向(X方向)のシール部30が形成された第1方向(X方向)の端部11A側に形成されていてもよい。その場合、蓋体50のシール部30側の端縁が天面11に接続され、加工部60が蓋体50のシール部30側に設けられる。
The outlet 20 may be formed on the end portion 11A side in the first direction (X direction) in which the seal portion 30 in the first direction (X direction) is formed. In that case, the edge of the lid 50 on the seal portion 30 side is connected to the top surface 11, and the processed portion 60 is provided on the seal portion 30 side of the lid 50.
本実施形態のシート包装体100において、加工部60は、天面11の第1方向(X方向)と交差する第2方向(Y方向)に延びている。具体的には、加工部60は、シール部40から第1方向(X方向)までの距離L3が約1mmの位置で、第2方向(Y方向)に沿ってシール部40と平行に延びている(図3、図8)。
In the sheet package 100 of the present embodiment, the processed portion 60 extends in the second direction (Y direction) intersecting the first direction (X direction) of the top surface 11. Specifically, the processed portion 60 extends parallel to the seal portion 40 along the second direction (Y direction) at a position where the distance L3 from the seal portion 40 to the first direction (X direction) is about 1 mm.

なお、第1方向(X方向)におけるシール部40と加工部60との距離L3は、本実施形態における距離に限定されない。例えば、シール部40と加工部60との距離L3は、第1方向(X方向)における取出口20の間隔L2に対して、0.5%以上20%以下であり、好ましくは1%以上15%以下、より好ましくは2%以上10%以下である。
The distance L3 between the seal portion 40 and the processed portion 60 in the first direction (X direction) is not limited to the distance in the present embodiment. For example, the distance L3 between the seal portion 40 and the processed portion 60 is 0.5% or more and 20% or less, preferably 1% or more and 15% or less, with respect to the distance L2 of the outlet 20 in the first direction (X direction). % Or less, more preferably 2% or more and 10% or less.
なお、第2方向(Y方向)における加工部60の長さ(幅W3)は、本実施形態における距離に限定されない。例えば、加工部60の長さ(幅W3)は、第2方向(Y方向)における取出口20の間隔(幅W2)に対して、65%以上100%以下であり、好ましくは70%以上100%以下、より好ましくは75~100%である(図3)。
The length (width W3) of the processed portion 60 in the second direction (Y direction) is not limited to the distance in the present embodiment. For example, the length (width W3) of the processed portion 60 is 65% or more and 100% or less, preferably 70% or more and 100% with respect to the interval (width W2) of the outlets 20 in the second direction (Y direction). % Or less, more preferably 75 to 100% (FIG. 3).
本実施形態では、加工部60は、第2方向(Y方向)の長さ(幅W3)が、取出口20の第2方向(Y方向)の幅W2と同じである(図1、図3、図8)。すなわち、加工部60が第2方向(Y方向)に沿って、蓋体50の第2方向(Y方向)の端縁53から端縁54まで形成されている(図8)。
In the present embodiment, the length (width W3) of the processed portion 60 in the second direction (Y direction) is the same as the width W2 in the second direction (Y direction) of the outlet 20 (FIGS. 1 and 3). , FIG. 8). That is, the processed portion 60 is formed along the second direction (Y direction) from the edge 53 to the edge 54 of the lid 50 in the second direction (Y direction) (FIG. 8).
なお、加工部60を設ける際の位置決めを容易にする観点から、加工部60の第2方向(Y方向)の長さ(幅W3)が取出口20の第2方向(Y方向)の幅W2より長くなるように、加工部60を設けてもよい。
From the viewpoint of facilitating positioning when the processed portion 60 is provided, the length (width W3) of the processed portion 60 in the second direction (Y direction) is the width W2 of the outlet 20 in the second direction (Y direction). The processed portion 60 may be provided so as to be longer.
本実施形態のシート包装体100では、加工部60が、ミシン目PFで形成されている(図1、図3、図8)。ここで、ミシン目PFは、カットC2とタイT2(2つのカットC2、C2間のカットされていない部分)が交互に配置されたものである(図8)。本実施形態では、加工部60を構成するミシン目PFは、カットC2の長さとタイT2の長さとの比が1:1になっている。
In the sheet package 100 of the present embodiment, the processed portion 60 is formed by a perforated PF (FIGS. 1, FIG. 3, and FIG. 8). Here, in the perforation PF, the cut C2 and the tie T2 (the uncut portion between the two cuts C2 and C2) are alternately arranged (FIG. 8). In the present embodiment, the perforation PF constituting the processed portion 60 has a ratio of the length of the cut C2 to the length of the tie T2 of 1: 1.

本実施形態に係るシート包装体100では、蓋体50に、天面11に接続された端縁51と反対側の端縁52に接着用シール70が設けられている(図1、図3)。ここで、天面11に接続された端縁51と反対側の端縁52は、天面11に接続されない自由端を構成する。
In the sheet package 100 according to the present embodiment, the lid 50 is provided with an adhesive seal 70 on the edge 52 opposite to the edge 51 connected to the top surface 11 (FIGS. 1 and 3). .. Here, the edge 52 on the opposite side of the edge 51 connected to the top 11 constitutes a free end that is not connected to the top 11.
接着用シール70は、蓋体50に固定された状態で天面11に接着するシールである。接着用シール70は、蓋体50の端縁52に固定された固定部71と、天面11に剥離可能に接着する粘着部72と、つまみ73とで構成されている。なお、接着用シール70の態様は、限定されず、例えば、基材(図示せず)に、接着剤が塗布された固定部71と、固定部71より接着力が弱い接着剤が塗布された粘着部72と、残りの部分に接着剤が塗布されていないつまみ73とが形成されたものを用いることができる(図1、図3、図9)。
The adhesive seal 70 is a seal that adheres to the top surface 11 in a state of being fixed to the lid body 50. The adhesive seal 70 is composed of a fixing portion 71 fixed to the edge 52 of the lid 50, an adhesive portion 72 that is detachably adhered to the top surface 11, and a knob 73. The mode of the adhesive seal 70 is not limited, and for example, a fixing portion 71 to which an adhesive is applied and an adhesive having a weaker adhesive force than the fixing portion 71 are applied to a base material (not shown). An adhesive portion 72 and a knob 73 having no adhesive applied to the remaining portion can be used (FIGS. 1, 3, and 9).
なお、接着用シール70に用いられる基材の材質は、限定されないが、上述の包装袋10に用いられる可撓性フィルム等の樹脂材料、紙材料、生分解性材料、バイオマス材料等を用いることができる。また、基材の形態は、限定されず、上述の包装袋10に用いられる単層フィルム、ラミネートフィルム、混合フィルム等を用いることができる。さらに、基材の厚みは、上述の包装袋10に用いられる可撓性フィルムと同じ厚みを採用することができる。

第1実施形態のシート包装体100では、上述のように、取出口20を再封可能に閉口する蓋体50が、蓋体50の閉口動作を遅延させる加工部60を有することで、取出口20を開口する方向に蓋体50を展開したときに、展開した蓋体50が取出口20を閉口する元の状態に戻ろうとする蓋体50の動きを遅くすることができる。これにより、取出口20からシートSを取り出す際に、展開された蓋体50が取出口20から離れた状態を維持することができる(図9、図10)。
In the sheet package 100 of the first embodiment, as described above, the lid 50 that resealably closes the outlet 20 has a processed portion 60 that delays the closing operation of the lid 50, so that the outlet 20 is taken out. When the lid 50 is deployed in the direction of opening 20, the movement of the lid 50 that the deployed lid 50 tries to return to the original state of closing the outlet 20 can be slowed down. As a result, when the sheet S is taken out from the outlet 20, the expanded lid 50 can be maintained in a state of being separated from the outlet 20 (FIGS. 9 and 10).
本実施形態では、このような構成により、取出口20を覆う蓋体50が設けられている場合でも、取出口20からシートSを取り出す際に、蓋体50が邪魔になりにくい(図9、図10)。そのため、本実施形態によれば、シートSの取り出しが容易なシート包装体100を提供することができる。
In the present embodiment, even if the lid 50 covering the outlet 20 is provided due to such a configuration, the lid 50 is less likely to be an obstacle when the sheet S is taken out from the outlet 20 (FIG. 9, FIG. FIG. 10). Therefore, according to the present embodiment, it is possible to provide the sheet package 100 in which the sheet S can be easily taken out.
また、本実施形態では、開裂した天面11の一部BLが取出口20を再封可能に閉口する蓋体50を構成することで、閉口された取出口20から包装袋10内にゴミや埃等(以下、塵埃という)が入りにくくなる。これにより、本実施形態では、シート包装体100を衛生的に使用することができる(図11)。
Further, in the present embodiment, a part BL of the cleaved top surface 11 constitutes a lid body 50 that closes the outlet 20 so that the outlet 20 can be resealed. Dust and the like (hereinafter referred to as dust) are less likely to enter. Thereby, in the present embodiment, the sheet package 100 can be used hygienically (FIG. 11).
さらに、本実施形態では、開裂した天面11の一部BLが取出口20を再封可能に閉口する蓋体50となり、蓋体50の端縁51が天面11に接続されていることで、開裂した天面11の一部BLを構成する蓋体50が、包装袋10から切り離されずに天面11に接続した小片BLとなる。そのため、本実施形態では、取出口20の開封時に断片(包装袋10から切り離された切れ端等)が発生しない(図9~図11)。
Further, in the present embodiment, a part BL of the cleaved top surface 11 becomes a lid body 50 that closes the outlet 20 so that the outlet 20 can be resealed, and the end edge 51 of the lid body 50 is connected to the top surface 11. The lid 50 forming a part BL of the cleaved top surface 11 becomes a small piece BL connected to the top surface 11 without being separated from the packaging bag 10. Therefore, in the present embodiment, fragments (such as pieces separated from the packaging bag 10) are not generated when the outlet 20 is opened (FIGS. 9 to 11).
第1実施形態のシート包装体100では、上述のように、蓋体50の加工部60が蓋体50のシール部40側に設けられていることで、天面11に接続された蓋体50の端縁51の近傍51Aが蓋体50の加工部60となる。蓋体50のシール部40側の端縁51の近傍51Aは、取出口20を開口するために蓋体50を展開したときに応力が生じやすい部分であるため、この部分に蓋体50の加工部60を設けることで、蓋体50の応力が緩和されやすくなる。そのため、本実施形態によれば、蓋体50の閉口動作を遅延させる機能を高めることができる(図9、図10)。
In the sheet package 100 of the first embodiment, as described above, the processed portion 60 of the lid body 50 is provided on the seal portion 40 side of the lid body 50, so that the lid body 50 connected to the top surface 11 is provided. 51A in the vicinity of the edge 51 of the lid 50 serves as a processed portion 60 of the lid body 50. Since the vicinity 51A of the edge 51 on the seal portion 40 side of the lid 50 is a portion where stress is likely to occur when the lid 50 is deployed to open the outlet 20, the lid 50 is processed in this portion. By providing the portion 60, the stress of the lid 50 can be easily relaxed. Therefore, according to the present embodiment, the function of delaying the closing operation of the lid 50 can be enhanced (FIGS. 9 and 10).
また、本実施形態では、取出口20がピロー包装のシール部40が形成された天面11の第1方向(X方向)の一方の端部11B側に形成されているため、取出口20が天面11全体に形成されることはない。そのため、取出口20が開口した後も包装袋10の形状が保たれやすく、包装袋10内でシートS(シート積層体SL)の収容状態が乱れにくい。そのため、本実施形態によれば、シート包装体100を最後まできれいに使用することができる(図9~図11)。
Further, in the present embodiment, since the outlet 20 is formed on one end 11B side of the first direction (X direction) of the top surface 11 on which the seal portion 40 of the pillow packaging is formed, the outlet 20 is formed. It is not formed on the entire top surface 11. Therefore, the shape of the packaging bag 10 is easily maintained even after the outlet 20 is opened, and the storage state of the sheet S (sheet laminate SL) in the packaging bag 10 is not easily disturbed. Therefore, according to the present embodiment, the sheet package 100 can be used cleanly to the end (FIGS. 9 to 11).
また、本実施形態では、取出口20をピロー包装のシール部40が形成された天面11の第1方向(X方向)の一方の端部11B側に形成することで、取出口20を天面11のシール部40側に開口させることができる。これにより、取出口20からシートSを取り出す際に、シートSを天面11側に引き出すことができ、また第1方向(X方向)に沿ってシール部40側にも引き出すこともできる。そのため、本実施形態によれば、使い勝手がよいシート包装体100を提供することができる(図9、図10)。
Further, in the present embodiment, the outlet 20 is formed on the one end 11B side of the first direction (X direction) of the top surface 11 on which the seal portion 40 of the pillow packaging is formed, so that the outlet 20 is heavenly. It can be opened on the seal portion 40 side of the surface 11. As a result, when the sheet S is taken out from the outlet 20, the sheet S can be pulled out to the top surface 11 side, and can also be pulled out to the seal portion 40 side along the first direction (X direction). Therefore, according to the present embodiment, it is possible to provide a sheet package 100 that is easy to use (FIGS. 9 and 10).
第1実施形態のシート包装体100では、上述のように、蓋体50の加工部60が天面11の第1方向(X方向)と交差する第2方向(Y方向)に延びることで、天面11に接続された蓋体50の端縁51に沿って加工部60を設けることができる。これにより、本実施形態では、蓋体50の応力がさらに緩和されやすくなり、蓋体50の閉口動作を遅延させる機能をさらに高めることができる(図9、図10)。
In the sheet package 100 of the first embodiment, as described above, the processed portion 60 of the lid 50 extends in the second direction (Y direction) intersecting the first direction (X direction) of the top surface 11. The processed portion 60 can be provided along the edge 51 of the lid 50 connected to the top surface 11. As a result, in the present embodiment, the stress of the lid 50 can be further relaxed, and the function of delaying the closing operation of the lid 50 can be further enhanced (FIGS. 9 and 10).
本実施形態では、上述のように、蓋体50の加工部60の第2方向(Y方向)の長さ(幅W3)を取出口20の第2方向(Y方向)の幅W2と同じ長さにすることで、蓋体50のシール部40側の端縁51の近傍51A(取出口20を開口するために蓋体50を展開したときに応力が生じやすい部分)全体に加工部60を設けることができる。そのため、本実施形態によれば、蓋体50の応力がさらに緩和されやすくなり、蓋体50の閉口動作を遅延させる機能をさらに高めることができる(図9、図10)。
In the present embodiment, as described above, the length (width W3) of the processed portion 60 of the lid 50 in the second direction (Y direction) is the same as the width W2 of the outlet 20 in the second direction (Y direction). By doing so, the processed portion 60 is provided over the entire 51A (the portion where stress is likely to occur when the lid 50 is expanded to open the outlet 20) near the edge 51 on the seal portion 40 side of the lid 50. Can be provided. Therefore, according to the present embodiment, the stress of the lid 50 can be further relaxed, and the function of delaying the closing operation of the lid 50 can be further enhanced (FIGS. 9 and 10).
本実施形態では、上述のように、蓋体50の加工部60をミシン目PFで構成することで、蓋体50の加工部60を形成する作業が容易になる。また、本実施形態では、蓋体50のミシン目PFが設けられた部分(加工部60)により、蓋体50の応力が緩和されるため、蓋体50の閉口動作を遅延させる機能を付与することができる(図1、図3、図8~図10)。
In the present embodiment, as described above, by forming the processed portion 60 of the lid body 50 with the perforated PF, the work of forming the processed portion 60 of the lid body 50 becomes easy. Further, in the present embodiment, the stress of the lid 50 is relaxed by the portion (processed portion 60) of the lid 50 provided with the perforated PF, so that a function of delaying the closing operation of the lid 50 is provided. This is possible (FIGS. 1, FIG. 3, FIGS. 8 to 10).
本実施形態では、上述のように、蓋体50の天面11に接続された端縁51と反対側の端縁52に接着用シール70が設けられていることで、接着用シール70が天面11の一部BLを開裂するためのトリガーTGとしてつまむことができる。そして、このトリガーTGを上方に引っ張ると、天面11の一部BLが開裂し、天面11に開口する取出口20が形成され、開裂した天面11の一部BLが取出口20を再封可能に閉口する蓋体50を構成する(図1、図3、図9~図11)。
In the present embodiment, as described above, the adhesive seal 70 is provided on the edge 52 on the opposite side of the edge 51 connected to the top surface 11 of the lid 50, so that the adhesive seal 70 is on the top. It can be pinched as a trigger TG for cleaving a part BL of the surface 11. Then, when this trigger TG is pulled upward, a part BL of the top surface 11 is cleaved to form an outlet 20 that opens to the top surface 11, and a part BL of the cleaved top surface 11 reopens the outlet 20. A lid 50 that can be sealed is configured (FIGS. 1, FIG. 3, FIGS. 9 to 11).
本実施形態では、このような構成により、包装袋10の天面11を押え付けずに取出口20を開封できる。これにより、本実施形態では、取出口20の開封時にシートSが破れるのを防ぐことができる(図1、図3、図9、図10)。
In the present embodiment, with such a configuration, the outlet 20 can be opened without pressing the top surface 11 of the packaging bag 10. Thereby, in the present embodiment, it is possible to prevent the sheet S from being torn when the outlet 20 is opened (FIGS. 1, FIG. 3, FIG. 9, FIG. 10).
また、本実施形態では、蓋体50にこのような接着用シール70が設けられていることで、取出口20を閉口した状態で蓋体50を天面11に接着することができる。これにより、蓋体50による取出口20の再封が容易である。また、取出口20を閉口した状態で、包装袋10の形状が保たれやすく、包装袋10内でシートS(シート積層体SL)の収容状態が乱れにくい。また、蓋体50を閉口した状態が維持されるため、閉口された取出口20からの包装袋10内に塵埃の進入を防ぐことができる(図1、図3、図9~図11)。
Further, in the present embodiment, since the lid 50 is provided with such an adhesive seal 70, the lid 50 can be adhered to the top surface 11 with the outlet 20 closed. As a result, the outlet 20 can be easily resealed by the lid body 50. Further, the shape of the packaging bag 10 is easily maintained in the state where the outlet 20 is closed, and the accommodation state of the sheet S (sheet laminate SL) in the packaging bag 10 is not easily disturbed. Further, since the closed state of the lid 50 is maintained, it is possible to prevent dust from entering the packaging bag 10 from the closed outlet 20 (FIGS. 1, FIG. 3, FIGS. 9 to 11).
なお、蓋体50にこのような接着用シール70が設けられていると、取出口20からシートSを取り出す際に、接着用シール70にシートSが貼り付くおそれがある。しかしながら、本実施形態では、上述のように、蓋体50の閉口動作を遅延させる加工部60を有するため、展開した蓋体50が取出口20を閉口する元の状態に戻ろうとする蓋体50の動きを遅くすることができ、蓋体50が邪魔になりにくい。そのため、本実施形態では、蓋体50に接着用シール70を設けた場合でも、接着用シール70にシートSが貼り付きにくい(図1、図3、図9、図10)。
If the lid 50 is provided with such an adhesive sticker 70, the sheet S may stick to the adhesive sticker 70 when the sheet S is taken out from the outlet 20. However, in the present embodiment, as described above, since the processing portion 60 for delaying the closing operation of the lid 50 is provided, the expanded lid 50 tries to return to the original state of closing the outlet 20. The movement of the lid 50 can be slowed down, and the lid 50 is less likely to get in the way. Therefore, in the present embodiment, even when the adhesive seal 70 is provided on the lid 50, the sheet S is difficult to adhere to the adhesive seal 70 (FIGS. 1, FIG. 3, FIG. 9, and FIG. 10).

Evaluation was carried out in the same manner as in Example 1 except that a linear outlet (cut line for cleavage) extending in the first direction was provided in the middle of the second direction of the packaging bag, and neither a lid nor a processed portion was provided. .. The results are shown in Table 1.
表1より、半楕円形状の取出口(開裂用切目線)が包装袋の長手方向の端部に設けられ、開裂用切目線が開裂するとの端縁の一部が天面に接続する蓋体が形成され、蓋体に蓋体の閉口動作を遅延させる加工部が設けられたシート包装体は、取出性、保管性、衛生性のいずれも良好であった(実施例1~10、図1~図19)。
From Table 1, a semi-elliptical outlet (cleavage line) is provided at the end of the packaging bag in the longitudinal direction, and a part of the edge when the tear line is cleaved is connected to the top surface. The sheet package in which the lid was formed and the lid was provided with a processed portion for delaying the closing operation of the lid was good in all of the ease of removal, storage, and hygiene (Examples 1 to 10, FIG. 1). ~ FIG. 19).
これに対して、蓋体の閉口動作を遅延させる加工部を蓋体に設けなかったシート包装体は、取出性が不良であった(比較例1)。また、直線形状の取出口(開裂用切目線)が包装袋の天面全体に設けられた従来のシート包装体は、保管性、衛生性が不良であった(比較例3)。
On the other hand, the sheet package in which the lid did not have a processed portion for delaying the closing operation of the lid had poor take-out property (Comparative Example 1). Further, the conventional sheet package in which a linear outlet (cut line for cleavage) is provided on the entire top surface of the packaging bag is poor in storability and hygiene (Comparative Example 3).
また、蓋体に接着用シールが設けられたシート包装体は、開封時のシートの破れ、シートの貼り付きは、いずれも良好であった(実施例8~10、図1~図7、図9~図11)。
Further, in the sheet package in which the adhesive seal was provided on the lid, the sheet was torn and the sheet was firmly attached at the time of opening (Examples 8 to 10, FIGS. 1 to 7, FIG. 9 to 11).
これに対して、蓋体に接着用シールが設けたが、蓋体の閉口動作を遅延させる加工部を蓋体に設けなかったシート包装体は、取出性、シートの貼り付きが不良であった(比較例2)。また、直線形状の取出口(開裂用切目線)を包装袋の天面全体に設けた従来のシート包装体は、開封時のシートの破れ、保管性、衛生性が不良であった(比較例3)。
On the other hand, the sheet wrapping body in which the lid body was provided with an adhesive seal but the lid body was not provided with a processed portion for delaying the closing operation of the lid body had poor takeability and sheet sticking. (Comparative example 2). In addition, the conventional sheet package in which a linear outlet (cut line for opening) is provided on the entire top surface of the packaging bag has poor sheet tearing, storability, and hygiene at the time of opening (Comparative Example). 3).
これらの結果から、包装袋の天面の一部が開裂すると天面に開口する取出口と、開裂した天面の一部で形成されて取出口を再封可能に閉口する蓋体とを有し、蓋体の端縁の一部が天面に接続され、蓋体に蓋体の閉口動作を遅延させる加工部が設けられているシート包装体は、シートの取り出しが容易であり、保管性、衛生性に優れたるシート包装体であることが判った。
From these results, there is an outlet that opens to the top surface when a part of the top surface of the packaging bag is torn, and a lid that is formed by a part of the torn top surface and closes the outlet so that the outlet can be resealed. However, a sheet package in which a part of the edge of the lid is connected to the top surface and the lid is provided with a processed portion for delaying the closing operation of the lid makes it easy to take out the sheet and is easy to store. It was found that the sheet packaging was excellent in hygiene.

Further, the lid body is provided with a processed portion for delaying the closing operation of the lid body, and an adhesive seal is provided on the edge opposite to the edge connected to the top surface. The sheet package is opened. It was found that the sheet was sometimes hard to tear and the sheet was hard to stick when the sheet was taken out from the outlet.
以上、本発明の実施形態について説明したが、本発明は特定の実施形態に限定されるものではなく、特許請求の範囲に記載された発明の範囲内において、種々の変形、変更が可能である。
Although the embodiments of the present invention have been described above, the present invention is not limited to the specific embodiments, and various modifications and modifications can be made within the scope of the invention described in the claims. ..
以下、本発明の好ましい態様を付記する。
Hereinafter, preferred embodiments of the present invention will be added.
本発明に係る第1の態様は、積層された複数枚のシートを収容する包装袋と、前記包装袋の天面の一部が開裂すると前記天面に開口する取出口と、開裂した前記天面の一部で形成され、前記取出口を再封可能に閉口する蓋体とを有し、前記蓋体の端縁の一部が前記天面に接続され、前記蓋体には、前記蓋体の閉口動作を遅延させる加工部が設けられている、シート包装体である。
The first aspect according to the present invention is a packaging bag for accommodating a plurality of laminated sheets, an outlet that opens to the top surface when a part of the top surface of the packaging bag is cleaved, and the cleaved top surface. It has a lid that is formed of a part of the surface and closes the outlet so that the outlet can be resealed, a part of the edge of the lid is connected to the top surface, and the lid is attached to the lid. It is a sheet package provided with a processed portion that delays the closing operation of the body.
本明細書において、包装袋の天面の一部が開裂すると天面に開口するとは、取出口が天面に形成された開裂用切目線で形成され、この開裂用切目線が開裂すると、包装袋の天面に開口が形成され、この開口が取出口となることを示す。取出口を再封可能に閉口するとは、開口した取出口を蓋体が覆うことを示す。端縁の一部が天面に接続されるとは、取出口が開口した後も蓋体が端縁の一部を介して天面に固定されていることを示す。
In the present specification, when a part of the top surface of the packaging bag is cleaved, it opens to the top surface. An opening is formed on the top surface of the bag, indicating that this opening serves as an outlet. Closing the outlet so that it can be resealed means that the lid covers the opened outlet. When a part of the edge is connected to the top surface, it means that the lid is fixed to the top surface through the part of the edge even after the outlet is opened.
蓋体の閉口動作を遅延させるとは、取出口を開口する方向に蓋体を展開したときに、蓋体が取出口を閉口する元の状態に戻ろうとする動きを遅くすることを示す。なお、蓋体が元の状態に戻ろうとする動きは、蓋体に加わった外力により蓋体の内部に生じる弾性応力(以下、応力という)による蓋体の動きであると考えられる。そして、蓋体の内部に生じた弾性応力分布が加工部により不連続ないし部分的に緩和される(以下、蓋体の応力が緩和されるという)ことが、蓋体の閉口動作が遅延する理由の一つと考えられる。
Delaying the closing operation of the lid means that when the lid is deployed in the direction of opening the outlet, the movement of the lid to return to the original state of closing the outlet is delayed. The movement of the lid to return to its original state is considered to be the movement of the lid due to the elastic stress (hereinafter referred to as stress) generated inside the lid due to the external force applied to the lid. The reason why the closing operation of the lid is delayed is that the elastic stress distribution generated inside the lid is discontinuously or partially relaxed by the processed portion (hereinafter, the stress of the lid is relaxed). It is considered to be one of.
第1の態様では、取出口を再封可能に閉口する蓋体が、蓋体の閉口動作を遅延させる加工部を有することで、取出口を開口する方向に蓋体を展開したときに、展開した蓋体が取出口を閉口する元の状態に戻ろうとする蓋体の動きを遅くすることができる。これにより、取出口からシートを取り出す際に、展開された蓋体が取出口から離れた状態を維持することができる。
In the first aspect, the lid that resealably closes the outlet has a processed portion that delays the closing operation of the lid, so that the lid is deployed when the lid is deployed in the direction of opening the outlet. It is possible to slow down the movement of the lid that tries to return to the original state in which the lid closes the outlet. As a result, when the sheet is taken out from the take-out port, the deployed lid body can be maintained in a state of being separated from the take-out port.
このような構成により、第1の態様では、取出口を覆う蓋体が設けられている場合でも、取出口からシートを取り出す際に、蓋体が邪魔になりにくい。そのため、第1の態様によれば、シートの取り出しが容易なシート包装体を提供することができる。
With such a configuration, in the first aspect, even if a lid covering the outlet is provided, the lid is less likely to get in the way when the sheet is taken out from the outlet. Therefore, according to the first aspect, it is possible to provide a sheet package in which the sheet can be easily taken out.
また、第1の態様では、開裂した天面の一部が取出口を再封可能に閉口する蓋体を構成することで、閉口された取出口から包装袋内にゴミや埃等(以下、塵埃という)が入りにくくなる。これにより、第1の態様では、シート包装体を衛生的に使用することができる。
Further, in the first aspect, a part of the cleaved top surface forms a lid that closes the outlet so that the outlet can be resealed, so that dust, dust, etc. It becomes difficult for dust to enter. Thereby, in the first aspect, the sheet package can be used hygienically.
さらに、第1の態様では、開裂した天面の一部が取出口を再封可能に閉口する蓋体となり、蓋体の端縁の一部が天面に接続されていることで、開裂した天面の一部を構成する蓋体が、包装袋から切り離されずに天面に接続した小片となる。そのため、第1の態様では、取出口の開封時に断片(包装袋から切り離された切れ端等)が発生しない。
Further, in the first aspect, a part of the cleaved top surface becomes a lid that resealably closes the outlet, and a part of the edge of the lid is connected to the top surface, so that the cleft is opened. The lid that forms part of the top surface is a small piece that is connected to the top surface without being separated from the packaging bag.
