At the time of use, the lid 22 is cut off along the splitting line 21 to form the outlet 20 (opening OP) in the top surface 11 (Fig. 5). As a result, the sheets S inside the box 10 can be taken out from the open take-out port 20 (FIG. 6).
　なお、本実施形態において、取出口２０の開裂用切目線２１は、シート収納箱１００の使用時において蓋２２を切り離すミシン目等の切り取り線を示す（図１、図４）。開裂用切目線２１は、カットＣとタイＴ（２つのカットＣ、Ｃ間のカットされていない部分）が交互に配置され、タイＴが破断すると両隣のカットＣが連続したカットになるミシン目である（図４）。 Note that in the present embodiment, the splitting line 21 of the outlet 20 indicates a perforation line or the like for separating the lid 22 when the sheet storage box 100 is used (FIGS. 1 and 4).

　取出口２０の蓋２２には、取出口２０の長さ方向（Ｘ方向）の端部２０Ｂ、２０Ｃにトリガー（図示せず）が設けられている。トリガーは、開裂用切目線（図示せず）で構成されている。トリガーの開裂用切目線も、カットとタイ（いずれも図示せず）が交互に配置され、タイが破断すると両隣のカットが連続したカットになるミシン目で構成することができる。 The lid 22 of the outlet 20 is provided with triggers (not shown) at ends 20B and 20C in the longitudinal direction (X direction) of the outlet 20. The trigger consists of a tearing score line (not shown). The trigger tearing score line may also consist of perforations in which cuts and ties (both not shown) are alternately arranged such that when the tie breaks, the adjacent cuts become continuous cuts.
　本実施形態では、トリガーの開裂用切目線が開裂すると、開口（図示せず）と一部が蓋２２に接続するフラップ（図示せず）が形成される。そして、該開口に指先を挿入して折り曲げたフラップと蓋２２を引き上げることで、蓋２２が天面１１から切り離され、取出口２０（開口ＯＰ）が形成される（図１、図５）。 In this embodiment, when the tearing score line of the trigger is cleaved, an opening (not shown) and a flap (not shown) partially connected to the lid 22 are formed. Then, by inserting a fingertip into the opening and pulling up the folded flap and the lid 22, the lid 22 is separated from the top surface 11, and the outlet 20 (opening OP) is formed (FIGS. 1 and 5).
　また、天面１１の取出口２０には、天面１１の裏面（シート収納箱１００の箱体１０の内側）から取出口２０を覆うように、樹脂フィルム３０が設けられていてもよい（図５）。樹脂フィルム３０には、長さ方向（Ｘ方向）に延びるスリット３１が形成されている。 In addition, a resin film 30 may be provided at the outlet 20 of the top surface 11 so as to cover the outlet 20 from the back surface of the top surface 11 (the inside of the box 10 of the sheet storage box 100) (Fig. 5).

As the material of the resin film 30, polyethylene, polypropylene, or the like can be used, but the material is not limited to these.
　このような樹脂フィルム３０が天面１１の裏面に設けられていることで、取出口２０から取り出されるシートＳは、樹脂フィルム３０のスリット３１を通過し、取出口２０の端縁に接しないため、シートＳが取出時に破れることを防ぐことができる。また、シートＳが取り出される際に次のシートＳが樹脂フィルム３０のスリット３１に係止されるため、ポップアップ式のシート積層体ＳＬの使用が容易になる。 Since such a resin film 30 is provided on the back surface of the top surface 11 , the sheet S taken out from the take-out port 20 passes through the slit 31 of the resin film 30 and does not come into contact with the edge of the take-out port 20 . , the sheet S can be prevented from tearing when it is taken out. Further, when the sheet S is taken out, the next sheet S is locked in the slit 31 of the resin film 30, so that the pop-up type sheet stack SL can be easily used.

Therefore, according to the third aspect, it is possible to obtain a sheet storage box in which the place of storage before and during use is not restricted.
　本発明に係る第４の態様は、前記箱体の表面積あたりの前記圧縮強度が３．６ｃＮ／ｃｍ２以上である、シート収納箱を有する。第４の態様では、箱体の表面積あたりの圧縮強度を３．６ｃＮ／ｃｍ２以上にすることで、シート収納箱を構成する箱体をよりコンパクト化しながら潰れにくくすることができる。そのため、第４の態様によれば、より置き場所が制限されず、しかも外出時の持ち運びがより容易なシート収納箱が得られる。 A fourth aspect of the present invention has a sheet storage box in which the compressive strength per surface area of the box is 3.6 cN/cm 2 or more. In the fourth aspect, by setting the compressive strength per surface area of the box to 3.6 cN/cm 2 or more, the box constituting the sheet storage box can be made more compact and less likely to collapse. Therefore, according to the fourth aspect, it is possible to obtain a sheet storage box in which the place of storage is not restricted and which is easier to carry when going out.
　本発明に係る第５の態様は、前記箱体の質量が１８．５ｇ以下である、シート収納箱を提供する。第５の態様では、箱体の質量を１８．５ｇ以下にすることで、シート収納箱を構成する箱体が軽量化されるため、箱体にシートが収容されたシート収納箱（シート収容体）全体として軽量化することができる。また、箱体の質量を１８．５ｇ以下にしても、箱体が潰れにくいため、シート収納箱の持ち運びがさらに容易になる。 A fifth aspect of the present invention provides a sheet storage box in which the mass of the box is 18.5 g or less. In the fifth aspect, by reducing the mass of the box to 18.5 g or less, the weight of the box constituting the sheet storage box is reduced. ) can be lightened as a whole. In addition, even if the mass of the box is 18.5 g or less, the box is less likely to be crushed, so that the sheet storage box can be carried more easily.
　本発明に係る第６の態様は、前記取出口は、前記所定の長さに対する前記所定の幅の比が０．２６以上０．３６以下である、シート収納箱を提供する。第６の態様では、取出口において所定の長さに対する所定の幅の比を０．２６以上０．３６以下にすることで、シートを取り出す際に箱体の浮き（または持ち上がり）を抑制することができる。そのため、第６の態様によれば、箱体がコンパクト化または軽量化されても、シートが取り出し易いシート収納箱が得られる。 A sixth aspect of the present invention provides a sheet storage box, wherein the outlet has a ratio of the predetermined width to the predetermined length of 0.26 or more and 0.36 or less. In the sixth aspect, by setting the ratio of the predetermined width to the predetermined length at the take-out port to 0.26 or more and 0.36 or less, the lifting (or lifting) of the box is suppressed when the sheet is taken out. can be done. Therefore, according to the sixth aspect, it is possible to obtain a sheet storage box from which sheets can be easily taken out even if the box body is made compact or lightweight.
　本発明に係る第７の態様は、前記取出口の面積が５０ｃｍ２以上７２ｃｍ２以下である、シート収納箱を提供する。本明細書において、取出口の面積は、天面に開口した状態の取出口の開口面積を示す。 A seventh aspect of the present invention provides a sheet storage box, wherein the outlet has an area of 50 cm 2 or more and 72 cm 2 or less. In this specification, the area of the outlet indicates the opening area of the outlet when it is open on the top surface.
　第７の態様では、取出口の面積を５０ｃｍ２以上７２ｃｍ２以下にすることで、箱体の圧縮強度を低下させずに、シートを取り出すための取出口の開口面積をできるだけ大きく天面に形成することができる。そのため、第７の態様によれば、箱体がコンパクト化または軽量化されても、取出口からのシートの取り出しが容易なシート収納箱が得られる。 In the seventh aspect, the area of the outlet is set to 50 cm 2 or more and 72 cm 2 or less, so that the opening area of the outlet for taking out the sheet is formed on the top surface as large as possible without lowering the compressive strength of the box. can do. Therefore, according to the seventh aspect, it is possible to obtain a sheet storage box from which sheets can be easily taken out from the take-out opening even if the box body is made compact or lightweight.
