Description

本発明は、ティッシュペーパーやウェットティッシュ、ペーパータオル、ポリ袋等のシート状の収納物を内部に収納する収納箱に関する。 The present invention relates to a storage box for storing sheet-shaped storage items such as tissue paper, wet tissue, paper towels, and plastic bags.

ティッシュペーパー等のシート状の収納物を積層状態で収納し、このシート状収納物の取出口が上部に形成された収納箱として、例えば特許文献１に記載のものが知られている。この収納箱では、収納物の残量が少なくなったときに、矩形状の底面の角部を頂点とする錐体状の部分を切離線に沿って切り離すか、あるいは、その底面の角部付近に接する側面の角部を切込線又は折込線に沿って切り込み又は折り込んで開口を形成することにより（同文献における図９乃至図１２参照）、底面と二側面が交わる底面の角部周辺の剛性を低下させることができる。その上で、側面に形成された折込線に沿って、側面を底面との交線に略平行に折り曲げ、底面を上方に押し上げることにより、底面を底上げして収納物を取出口に近づけ、残量が少なくなった収納物の取出しを容易としている。 As a storage box in which sheet-like storage items such as tissue paper are stored in a stacked state and an outlet of the sheet-like storage item is formed in the upper part, for example, the one described in Patent Document 1 is known. In this storage box, when the remaining amount of the stored item is low, the cone-shaped part having the corner of the rectangular bottom is cut off along the separation line, or near the corner of the bottom By forming the opening by cutting or folding the corner portion of the side surface in contact with the cut line or along the folding line (see FIGS. 9 to 12 in the same document), around the corner portion of the bottom surface where the bottom surface and the two side surfaces intersect Stiffness can be reduced. Then, along the fold line formed on the side surface, the side surface is bent substantially parallel to the line of intersection with the bottom surface, and the bottom surface is pushed upward to raise the bottom surface and bring the stored item closer to the outlet, leaving It makes it easy to take out the stored items when the amount is small.

上記従来の収納箱では、底面が全体的に底上げされるので、例えば収納物がティッシュペーパーのように薄手で柔らかいものである場合にも、その一部だけが持ち上げられて他部が持ち上げられずに取り出しにくいといったような不都合は解消される。一方、使用者により底面が全体的に底上げされるためには、使用者が折込みを容易に行える必要があり、もしこの折込作業が使用者にとって難しいものであると、結局は収納物の残量が少なくなっても収納箱は底上げされることなく使用され続けることになる。 In the above conventional storage box, the bottom surface is raised as a whole, so even if the stored item is thin and soft like tissue paper, only a part of it is lifted and the other part is not lifted. Inconveniences such as being difficult to remove are eliminated. On the other hand, in order for the user to raise the entire bottom surface, it is necessary for the user to be able to fold it easily, and if this is difficult for the user, the remaining amount of stored items will eventually be increased. The storage box will continue to be used without raising the bottom even if the number is reduced.

しかしながら、上記従来の収納箱では、特に底面の長さ寸法（辺の長さ）が大きい場合に折込みにくさを伴うことがあり、使用者の折込作業が容易となるように実用性を高める必要があった。 However, in the above conventional storage box, it may be difficult to fold especially when the length dimension (side length) of the bottom is large, and it is necessary to improve the practicality so that the user can easily fold it. was there.

すなわち、上記従来の収納箱の折込作業時に、使用者は、左右の親指で側面又は底面周縁部の（使用者から見て）左右両端に力を加え、これを収納箱の向きを変えながら各側面又は各底面周縁部について変形量のバランスをとりつつ順次行い、底上げを最終的に完了させる。よって、使用者が底上げを容易に行うためには、左右の親指の力が不用意な変形を生じさせない程度に効率的に側面又は底面周縁部に伝達されることを要するが、上記従来の収納箱では、底面の長さ寸法が大きいと、左右の親指による力の作用点が離れ、側面又は底面周縁部を長さ寸法全域に亘って変形させるために大きな力を加える必要がある一方、その大きな力の作用点付近だけ不用意に変形してしまうおそれもあり、誰もが習熟を要することなく簡単に底上げすることができる構造とは必ずしもいえない場合があった。 That is, during the folding operation of the conventional storage box, the user applies force to the left and right edges (as viewed from the user) with the left and right thumbs while changing the direction of the storage box. The side surface or each bottom surface peripheral portion is sequentially performed while balancing the deformation amount, and the bottom raising is finally completed. Therefore, in order for the user to easily raise the bottom, it is necessary that the force of the left and right thumbs be efficiently transmitted to the side surface or the peripheral edge of the bottom surface without causing inadvertent deformation. In the box, if the length of the bottom surface is large, the point of action of the force by the left and right thumbs is separated, and it is necessary to apply a large force in order to deform the side surface or the bottom edge over the entire length dimension, There is a possibility that only the vicinity of the point of application of a large force may be inadvertently deformed, and it may not always be a structure that can be easily raised without anyone having to learn.

本発明は、上記の問題点に鑑みてなされたもので、底面の長さ寸法が大きい場合にも容易に底上げすることができるシート状収納物の収納箱を提供することを課題としている。 This invention is made | formed in view of said problem, and makes it a subject to provide the storage box of the sheet-like stored article which can be easily raised even when the length dimension of a bottom face is large.

収納箱１の生産に供する紙製のシート材は、例えば図３に示すように加工されている（同図において、図１及び図２の各所と対応する箇所には同一の符号を付して説明を省略する。）。このシート材１６は、収納箱１の展開図様のもので、これに対して所定の手順で折曲げ及び貼着を行うことにより収納箱１になる。 The paper sheet material used for the production of the storage box 1 is processed, for example, as shown in FIG. 3 (in the figure, parts corresponding to those in FIGS. 1 and 2 are given the same reference numerals). The description is omitted.) This sheet material 16 is a developed view of the storage box 1, and the storage box 1 is formed by bending and sticking the sheet material 16 according to a predetermined procedure.

シート材１６では、長側面４、天面２、長側面４、底面３及び貼代１７がこの順で連設され、これらを区画する長辺２ａ，３ａは凹状にプレス加工されている。 In the sheet material 16, the long side surface 4, the top surface 2, the long side surface 4, the bottom surface 3, and the pasting margin 17 are connected in this order, and the long sides 2 a and 3 a that define these are pressed into a concave shape.

また、天面２の長さ方向の両端部に隣接して短側面上片１８，１８が形成され、底面３の長さ方向の両端部に隣接して短側面下片１９，１９が形成され、短側面下片１９，１９の先端には貼代２０，２０が設けられている。天面２と短側面上片１８とを区画する短辺２ｂ、及び、底面３と短側面下片１９とを区画する短辺３ｂは、凹状にプレス加工されている。 Short side upper pieces 18 and 18 are formed adjacent to both ends of the top surface 2 in the length direction, and short side lower pieces 19 and 19 are formed adjacent to both ends of the bottom surface 3 in the length direction. The sticking allowances 20 and 20 are provided at the tips of the short side lower pieces 19 and 19. The short side 2b that partitions the top surface 2 and the short side upper piece 18 and the short side 3b that partitions the bottom surface 3 and the short side lower piece 19 are pressed into a concave shape.

さらに、長側面４の長さ方向の両端部には、これに隣接して耳部２１，２１が形成されている。長側面４と耳部２１との境界には、凹状にプレス加工された折込線２２及び補助切込線１３が設けられている。 Furthermore, the ear | edge parts 21 and 21 are formed in the both ends of the length direction of the long side surface 4 adjacent to this. At the boundary between the long side surface 4 and the ear portion 21, a folding line 22 and an auxiliary cutting line 13 that are pressed into a concave shape are provided.

このシート材１６を組み立てて収納箱１とするには、まず、長辺２ａ，３ａを山折りし、貼代１７に糊付けしてこれを図３における上方の長側面４の裏面に貼着する。なお、貼代１７には、その長側面４における折込線１５と重なり合う位置に、凹状にプレス加工された折込線２３が形成されており、後述する底上げ時に、その折込線１５の折込みが阻害されないようになっている。 In order to assemble the sheet material 16 into the storage box 1, first, the long sides 2a and 3a are folded in a mountain, and glued to the pasting allowance 17, which is adhered to the back surface of the upper long side surface 4 in FIG. . In addition, in the pasting margin 17, a folding line 23 that is pressed into a concave shape is formed at a position that overlaps with the folding line 15 on the long side surface 4, and the folding of the folding line 15 is not hindered when raising the bottom, which will be described later. It is like that.

次に、天面２、底面３及び２つの長側面４で囲まれた中空内部にティッシュペーパーＴを入れ、折込線２２を山折りして耳部２１を内方に折り曲げる。 Next, the tissue paper T is put into the hollow space surrounded by the top surface 2, the bottom surface 3, and the two long side surfaces 4, the folding line 22 is folded in a mountain, and the ear portion 21 is folded inward.

続いて、短辺３ｂを山折りして短側面下片１９を上方に折り曲げ、短辺２ｂを山折りして短側面上片１８を下方に折り曲げ、貼代２０に糊付けした上でこれを短側面上片１８の裏面に貼着する。これにより、短側面５が形成され、収納箱１が完成する。 Subsequently, the short side 3b is folded in a mountain and the short side surface lower piece 19 is folded upward, the short side 2b is folded in a mountain and the short side surface upper piece 18 is folded downward and glued to the adhesive allowance 20 and then short. It sticks on the back surface of the side upper piece 18. Thereby, the short side surface 5 is formed and the storage box 1 is completed.

この収納箱１において、ティッシュペーパーＴの残量が少なくなった場合には、使用者は、ティッシュペーパーＴを取り出しやすくするために、底上げをすればよい。 In this storage box 1, when the remaining amount of the tissue paper T is reduced, the user may raise the bottom so that the tissue paper T can be easily taken out.

この底上げ時の手順は、まず、図４に示すように、切込線９，１０及び補助切込線１３，１４のすべてについてミシン目を破断し、切込みを形成する（切込みには、対応する切込線と同一の符号を付す。）。 As shown in FIG. 4, the procedure for raising the bottom is first to break the perforation for all of the cut lines 9 and 10 and the auxiliary cut lines 13 and 14 to form cuts (corresponding to the cuts). (The same reference sign as that of the score line is attached.)

次に、図５に示すように、切込み１３，１４を外縁として形成される三角形状の折込片２４を、折込線１５を山折りして収納箱１の内側に折り込むとともに、切込み１０，１４を外縁として形成される三角形状の折込片２５を、折込線１２を山折りして収納箱１の内側に折り込む。 Next, as shown in FIG. 5, the triangular folding piece 24 formed with the notches 13 and 14 as the outer edges is folded into the inside of the storage box 1 by folding the folding line 15 and the notches 10 and 14 are A triangular folding piece 25 formed as an outer edge is folded inside the storage box 1 by folding the folding line 12 in a mountain.

そして、図６に示すように、左右の親指Ｆ_Ｌ，Ｆ_Ｒを、長辺３ａ上の交点３ｆと中間点９ａ（ここでは、中間点９ａは、切込み９の中間点とする。）との間でなるべく離間した位置（一方の指を交点３ｆの近く、他方の指を中間点９ａの近く）に当て、そこに押込力を加える。すると、その交点３ｆと中間点９ａとの間の部分が、折込線７，８が山折りとなるように、かつ、長辺３ａ、短辺３ｂ及び折込線１１，１２が谷折りとなるように変形するので、このような押込みをその長辺３ａの残り半分及びもう一方の長辺３ａについて順次行う。 Then, as shown in FIG. 6, the left and right thumbs _F L, the _{F R,} (in this case, the midpoint 9a is a midpoint of the cuts 9.) Intersection 3f and the intermediate point 9a on the long side 3a and the A position between them as far as possible (one finger close to the intersection 3f and the other finger close to the intermediate point 9a) is applied with a pushing force. Then, in the portion between the intersection 3f and the intermediate point 9a, the folding lines 7 and 8 are mountain-folded, and the long side 3a, the short side 3b and the folding lines 11 and 12 are valley-folded. Therefore, such pushing is sequentially performed for the remaining half of the long side 3a and the other long side 3a.

以上の手順により、図７に示すように、長側面４及び短側面５の下部４ａ，５ａが折込線７，８に沿って中空内部Ｓの側に折り込まれ、底面３は略全面的に底上げされ、積層状態にあるティッシュペーパーＴは全体的に取出口６に接近するので、その取出しが容易となる。 By the above procedure, as shown in FIG. 7, the lower portions 4a and 5a of the long side surface 4 and the short side surface 5 are folded along the folding lines 7 and 8 toward the hollow interior S, and the bottom surface 3 is raised almost entirely. In addition, since the tissue paper T in the laminated state approaches the take-out port 6 as a whole, the take-out becomes easy.

この実施の形態に係る収納箱１によれば、切込みの形成を容易とする切込線９，１０が底面３の長辺３ａから中心部３ｄに向けて設けられ、使用者は、その切込線９，１０により切込み９，１０を形成した上で底上げすることができるので、底上げ時に長側面４とともに折り込まなければならない底面３の長さが、切込み９，１０によりＬ_１からＬ_２（図２参照）に分断・短縮され、使用者の左右の親指Ｆ_Ｌ，Ｆ_Ｒは、分断・短縮された中での両端位置において底面３又は長側面４に押込力を作用させる。 According to the storage box 1 according to this embodiment, the cut lines 9 and 10 that facilitate the formation of the cuts are provided from the long side 3a of the bottom surface 3 toward the center 3d, and the user can cut the cuts. Since the bottoms 3 can be raised after the cuts 9 and 10 are formed by the lines 9 and 10, the length of the bottom surface 3 that must be folded together with the long side surface 4 when the bottom is raised is changed from L ₁ to L ₂ by the cuts 9 and 10 (see FIG. is divided, shortened to 2 reference), the left and right thumbs F _L of the _user, F _R exerts a pushing force on the bottom 3 or length side 4 at both ends position in which the cutting-shortened.

詳細には、切込線１０が長辺３ａの端部３ｃから底面３の中心部３ｄに向けて設けられているので、底上げ時に折り込まなければならない底面３の長さ、すなわち、底上げ時の左右の親指Ｆ_Ｌ，Ｆ_Ｒによる押込力の作用点間距離は、切込線１０が中心部３ｄに向かい短辺３ｂから離れる分（端部３ｃと交点３ｆとの離間距離分）だけ小さくなる。その上、ここでは切込線９が長側面４から底面３にかけて設けられ、切込線９により形成される切込み９が長辺３ａを横切る。よって、底上げ時に折り込まなければならない長側面４の長さが底面３の長さと同様に切込み９により分断・短縮され、長側面４と底面３が交わってなる稜線周辺の剛性も低下する。 Specifically, since the score line 10 is provided from the end 3c of the long side 3a toward the center 3d of the bottom surface 3, the length of the bottom surface 3 that must be folded when raising the bottom, that is, the left and right when raising the bottom thumb F _L, pushing force of the distance from the application point by F _R of smaller extent that score lines 10 is separated from the short sides 3b toward the central portion 3d (distance portion of the end portion 3c and the intersection 3f). In addition, here, the score line 9 is provided from the long side surface 4 to the bottom surface 3, and the score 9 formed by the score line 9 crosses the long side 3a. Therefore, the length of the long side surface 4 that must be folded when raising the bottom is divided and shortened by the cut 9 similarly to the length of the bottom surface 3, and the rigidity around the ridge line formed by the intersection of the long side surface 4 and the bottom surface 3 is also reduced.

さらに、長辺３ａの端部３ｃから長側面４と短側面５との交線（折込線２２）に沿って衝合点７ａまで、及び、長辺３ａの端部３ｃから底面３と長側面４との交線（長辺３ａ）に沿って交点３ｆまで、切込みの形成を容易とする補助切込線１３，１４が設けられ、切込線１０及び補助切込線１３，１４による切込み１０，１３，１４を外縁として折込片２４，２５が形成されるので、底上げ時には、その折込片２４，２５を中空内部Ｓの側に折り込むことにより、底面３、長側面４及び短側面５が集まる長辺３ａの端部３ｃ（底面３の角部）周辺の剛性を低下させることができる。 Furthermore, from the end 3c of the long side 3a to the abutting point 7a along the intersection line (folding line 22) between the long side surface 4 and the short side surface 5, and from the end 3c of the long side 3a to the bottom surface 3 and the long side surface 4 Auxiliary incision lines 13 and 14 are provided to facilitate the formation of the incision along the intersection line (long side 3a) up to the intersection 3f, and the incision 10 by the incision line 10 and the auxiliary incision lines 13 and 14, Since the folding pieces 24 and 25 are formed with the outer edges 13 and 14 as outer edges, when the bottom is raised, the folding pieces 24 and 25 are folded toward the hollow interior S so that the bottom surface 3, the long side surface 4 and the short side surface 5 are gathered together. The rigidity around the end 3c (corner of the bottom surface 3) of the side 3a can be reduced.

したがって、収納箱１は、切込線９，１０により押込力の作用点間距離の分断・短縮が図られるとともに長側面４と底面３が交わってなる稜線周辺の剛性低下も図られ、加えて、補助切込線１３，１４により底面３の角部周辺の剛性低下も図られることによって、底上げが容易となっている。 Therefore, the storage box 1 can cut and shorten the distance between the points of action of the pushing force by the cut lines 9 and 10, and can also reduce the rigidity around the ridge line where the long side surface 4 and the bottom surface 3 intersect. Further, the auxiliary cutting lines 13 and 14 can reduce the rigidity around the corners of the bottom surface 3, thereby facilitating raising the bottom.

また、収納箱１では、折込みを容易とする折込線７，８が、長側面４及び短側面５においてそれらと底面３との交線に略平行に設けられ、折込線１１，１２が、４つの切込線１０のうち隣接するもの同士について、その底面３の中心部３ｄ側の端部１０ａを結ぶように設けられ、折込線１５が、折込片２４について設けられているので、底面３、長側面４、短側面５及び折込片２４，２５の折込みが容易で、底上げの容易性を高めている。 Further, in the storage box 1, folding lines 7 and 8 that facilitate folding are provided on the long side surface 4 and the short side surface 5 substantially in parallel with the intersection line between the bottom surface 3 and the folding lines 11 and 12. Adjacent ones of the two cut lines 10 are provided so as to connect the end 10a on the center 3d side of the bottom surface 3 and the folding line 15 is provided for the folding piece 24. The long side surface 4, the short side surface 5 and the folding pieces 24 and 25 are easily folded, and the ease of raising the bottom is enhanced.

なお、折込片２４，２５の折込みについては、強い力を加えてしっかり行うのではなく軽く行えばよい。こうすることにより、底上げの完了時には紙の復元力も作用してそれらの折込みにより生じた開口が塞がれるような状態となり（図７参照）、例えばティッシュペーパーＴが保湿性を有するものである場合に、開口を通じた通気を防止して乾燥を抑制することができる。 The folding of the folding pieces 24 and 25 may be performed lightly rather than by applying a strong force. By doing so, when the bottom raising is completed, the restoring force of the paper also acts to close the opening caused by the folding (see FIG. 7). For example, when the tissue paper T has moisture retention Further, it is possible to prevent the air from passing through the opening and to suppress drying.

（第２実施形態）
図８は、実施の形態の他の例（第２実施形態）としての収納箱１’を示しており、図９は、当該収納箱１’の生産に供する紙製のシート材１６’を示している。 (Second Embodiment)
FIG. 8 shows a storage box 1 ′ as another example (second embodiment) of the embodiment, and FIG. 9 shows a paper sheet material 16 ′ used for production of the storage box 1 ′. ing.

本実施の形態の収納箱１’は、以下の点を除き、第１実施形態の収納箱１とほぼ同様の構成である。すなわち、収納箱１における各長側面４から底面３にかけて、同収納箱１の長さ方向の略中央に位置するように設けられている切込線９と、長辺３ａの端部３ｃから、底面３と長側面４との交線である長辺３ａに沿って設けられている補助切込線１４が、第２実施形態の収納箱１’では存在していない点が異なっている。 The storage box 1 ′ of the present embodiment has substantially the same configuration as the storage box 1 of the first embodiment except for the following points. That is, from each long side surface 4 to the bottom surface 3 in the storage box 1, from the cut line 9 provided so as to be located at the approximate center in the length direction of the storage box 1, and the end 3 c of the long side 3 a, The difference is that the auxiliary cut line 14 provided along the long side 3a, which is a line of intersection between the bottom surface 3 and the long side surface 4, does not exist in the storage box 1 'of the second embodiment.

したがって、底面３には、長辺３ａ，３ａの各両端部３ｃ，３ｃから中心部３ｄに向けて、切込線９と同様にミシン目状に加工された４本の切込線（角部切込線）１０が設けられているとともに、長辺３ａ，３ａの各両端部３ｃ，３ｃを起点として長側面４と短側面５の交線に沿って補助切込線１３が設けられている。なお、この場合の補助切込線１３は、長辺３ａのやや中央部側となるように、短辺３ｂと平行となるように形成されていれば、切込線１０と干渉しないため、折り込みをしやすくなるため好適である。 Therefore, on the bottom surface 3, four cut lines (corner portions) processed in a perforated manner in the same manner as the cut lines 9 from the both end portions 3 c and 3 c of the long sides 3 a and 3 a toward the center portion 3 d. (Cut line) 10 is provided, and auxiliary cut lines 13 are provided along the intersecting line of the long side surface 4 and the short side surface 5 starting from both end portions 3c, 3c of the long sides 3a, 3a. . The auxiliary score line 13 in this case does not interfere with the score line 10 if it is formed so as to be slightly parallel to the short side 3b so as to be slightly on the center side of the long side 3a. This is preferable because it is easy to perform.

また、折込みを容易とするために、裏面側から見て凹状にプレス加工された折込線７，８が、長側面４及び短側面５においてそれらと底面３との交線である長辺３ａ及び短辺３ｂと略平行になるように設けられている。底面３には、折込線７，８と同様に、裏面側から見て凹状にプレス加工された折込線１１，１２が、底面３と、長側面４及び短側面５との各交線である長辺３ａ及び短辺３ｂと略平行になるように設けられている。 Further, in order to facilitate folding, the folding lines 7 and 8 that are pressed into a concave shape when viewed from the back side are the long sides 3a and the long sides 3a that are the intersections between the long side 4 and the short side 5 and the bottom 3 It is provided so as to be substantially parallel to the short side 3b. Similar to the folding lines 7 and 8, the folding lines 11 and 12 that are pressed into a concave shape when viewed from the back side are the intersection lines of the bottom surface 3, the long side surface 4, and the short side surface 5. It is provided so as to be substantially parallel to the long side 3a and the short side 3b.

続いて、本実施の形態における収納箱１’の使用法について説明する。 Subsequently, a method of using the storage box 1 ′ in the present embodiment will be described.

図１０に示すように、左右の親指（図示せず）を、各長辺３ａの略中間点に当て、そこに押込力を加えて、折込線７，８，１１，１２が表面側から見て山折りとなり、かつ、長辺３ａ、短辺３ｂが表面側から見て谷折りとなるように、すなわち、底面３が凸状となるように変形させる。そして、図１１に示すように、左右の親指（図示せず）を各短辺３ｂの略中間点に当て、そこに押込力を加え、折込線７，８が山折りとなり、長辺３ａ、短辺３ｂがそれぞれ長側面４及び短側面５に当接するとともに、折込線１１，１２が底面３に対して略フラットとなるように、底面３を凹状に変形させる（図１２，図１３）。 As shown in FIG. 10, the left and right thumbs (not shown) are applied to the approximate middle point of each long side 3a, and a pushing force is applied thereto, so that the folding lines 7, 8, 11, 12 are viewed from the surface side. The long side 3a and the short side 3b are deformed so as to form a valley when viewed from the front side, that is, the bottom surface 3 is convex. Then, as shown in FIG. 11, the left and right thumbs (not shown) are applied to the approximate middle point of each short side 3b, a pressing force is applied thereto, the folding lines 7 and 8 are mountain-folded, and the long side 3a, The short side 3b is in contact with the long side surface 4 and the short side surface 5, respectively, and the bottom surface 3 is deformed into a concave shape so that the folding lines 11 and 12 are substantially flat with respect to the bottom surface 3 (FIGS. 12 and 13).

このような二段階の手順により、第１実施形態の収納箱１と同様に、長側面４及び短側面５の下部４ａ，５ａが折込線７，８を境に中空内部Ｓの側に折り込まれ、長側面４及び短側面５の壁面に当接することによって、当該折込線７，８が新たな長辺及び短辺となるように変形することになる。これにより、底面３は略全面的に底上げされ、積層状態にあるティッシュペーパーＴは全体的に取出口６に接近するので、その取出しが容易となる。 By such a two-step procedure, the lower side 4a, 5a of the long side surface 4 and the short side surface 5 is folded into the hollow interior S side with the folding lines 7, 8 as in the case of the storage box 1 of the first embodiment. By making contact with the wall surfaces of the long side surface 4 and the short side surface 5, the folding lines 7 and 8 are deformed to become new long sides and short sides. As a result, the bottom surface 3 is raised almost entirely, and the tissue paper T in the laminated state is brought close to the take-out port 6 as a whole, so that the take-out becomes easy.

この実施の形態に係る収納箱１’によれば、まず底面３の両長辺３ａに押込力を加えることにより、底面３が容易に凸条に変形することになる。このとき、切込みの形成を容易とする切込線１０と補助切込線１３が設けられており、また、底面３に折込線１１，１２が設けられているため、当該切込線１０及び補助切込線１３により形成されている切込部分が離間し、当該折込線１１、１２に沿って、長側面４及び底面３の長辺３ａを容易に変形させることができる。そして、その後に、短側面５及び底面３の短辺３ｂに押込力を加え、底面３の凸部を下方に押し込むことによって、折込線１１，１２が底面３に対して略フラットとなるように、底面３を凹状に変形させることができる。このように、二段階の作業で容易に収納箱１’を底上げすることができることになる。 According to the storage box 1 ′ according to this embodiment, first, by applying a pressing force to both the long sides 3 a of the bottom surface 3, the bottom surface 3 is easily deformed into a ridge. At this time, the cut line 10 and the auxiliary cut line 13 that facilitate the formation of the cut are provided, and the fold lines 11 and 12 are provided on the bottom surface 3. The cut portions formed by the cut lines 13 are separated from each other, and the long sides 4 a and the long sides 3 a of the bottom surface 3 can be easily deformed along the cut lines 11 and 12. After that, by applying a pressing force to the short side surface 5 and the short side 3 b of the bottom surface 3 and pressing the convex portion of the bottom surface 3 downward, the folding lines 11 and 12 become substantially flat with respect to the bottom surface 3. The bottom surface 3 can be deformed into a concave shape. In this way, the storage box 1 'can be easily raised in two steps.

なお、折込線７，８，１１，１２は、事前のプレス加工により、裏面側から見て凹状となるように加工されているため、裏面側から谷折りとなるように容易に折り込み変形させることができる。 In addition, since the folding lines 7, 8, 11, and 12 are processed so as to have a concave shape when viewed from the back side by prior press processing, they can be easily folded and deformed so as to be valley-folded from the back side. Can do.

（第３実施形態）
図１４は、実施の形態の他の例（第３実施形態）として収納箱２６を示し、図１５は、その生産に供するシート材２７を示す。収納箱２６は、収納箱１と略同様の構成を有するが、切込線１０の代わりに補助切込線１３，１４と同一長さの補助切込線２８が端部３ｃから短辺３ｂに沿って設けられ、かつ、この補助切込線２８の端部２８ａと交点３ｆとの間に凹状にプレス加工された折込線２９が設けられている点が異なる。収納箱２６の底上げ時には、折込片２５の代わりに、切込線１４，２８により形成される切込み１４，２８を外縁とする三角形状の折込片３０が折り込まれる。 (Third embodiment)
FIG. 14 shows a storage box 26 as another example (third embodiment) of the embodiment, and FIG. 15 shows a sheet material 27 used for the production. The storage box 26 has substantially the same configuration as that of the storage box 1, but an auxiliary cut line 28 having the same length as the auxiliary cut lines 13 and 14 instead of the cut line 10 extends from the end 3 c to the short side 3 b. The difference is that a folding line 29 is provided which is provided along the edge 28a of the auxiliary cutting line 28 and pressed into a concave shape between the intersection 3f. When raising the bottom of the storage box 26, instead of the folding piece 25, a triangular folding piece 30 having the notches 14 and 28 formed by the cutting lines 14 and 28 as outer edges is folded.

この収納箱２６では、底上げ時に折り込まれなければならない底面３の長さが、切込み９によりＬ_１からＬ_３（図１４参照）に分断・短縮される。 In the storage box 26, the length of the bottom surface 3 that must be folded when the bottom is raised is divided and shortened from L ₁ to L ₃ (see FIG. 14) by the cut 9.

（第４実施形態）
図１６は、実施の形態のさらに他の例（第４実施形態）として収納箱３１を示し、図１７は、その生産に供するシート材３２を示す。シート材３２は、シート材１６の折込線１５に代えてミシン目状に加工された補助切込線３３が設けられたもので、補助切込線３３は、長辺３ａに対して切込線１０と線対称な形状を呈する。すなわち、補助切込線３３は、長辺３ａの端部３ｃから長側面４の中心部４ｂ（長側面４において２本の対角線が交差する点を含む広がりをもった領域）に向けて設けられ、補助切込線３３の端部３３ａは折込線７上に位置する。収納箱３１の底上げ時には、補助切込線３３のミシン目を破断して切込み３３を形成し、切込み１３，３３で囲まれた三角形状の折込片を折り込めばよい。 (Fourth embodiment)
FIG. 16 shows a storage box 31 as still another example (fourth embodiment) of the embodiment, and FIG. 17 shows a sheet material 32 used for production. The sheet material 32 is provided with an auxiliary cut line 33 processed into a perforation instead of the folding line 15 of the sheet material 16, and the auxiliary cut line 33 is formed with respect to the long side 3a. 10 and a line-symmetric shape. That is, the auxiliary score line 33 is provided from the end 3c of the long side 3a toward the center 4b of the long side surface 4 (a region having a spread including a point where two diagonal lines intersect on the long side surface 4). The end 33 a of the auxiliary score line 33 is located on the score line 7. When raising the storage box 31, the perforation of the auxiliary cut line 33 may be broken to form the cut 33, and the triangular folded piece surrounded by the cuts 13, 33 may be folded.

この収納箱３１では、底上げ時に折り込まなければならない長側面４の下部４ａの折込線７に沿った長さ（２つの端部３３ａ，３３ａで区画される折込線７の長さ）が、補助切込線３３が長側面４と短側面５との交線から離れる分（Ｌ_１／２−Ｌ_２）だけ小さくなる。ここでは、特に、切込線１０が長辺３ａの端部３ｃから底面３の中心部３ｄに向けて設けられており、底上げ時に折り込まなければならない底面３の折込線１１に沿った長さも小さくなるので、長側面４及び底面３の折込箇所（折込線７，１１で挟まれた領域）の短縮化が相俟って底上げが極めて容易となる。 In this storage box 31, the length along the folding line 7 of the lower part 4 a of the long side surface 4 that must be folded when the bottom is raised (the length of the folding line 7 defined by the two end portions 33 a and 33 a) is The lead wire 33 becomes smaller by the distance (L ₁ / 2-L ₂ ) that is away from the intersection line between the long side surface 4 and the short side surface 5. Here, in particular, the cutting line 10 is provided from the end 3c of the long side 3a toward the center 3d of the bottom surface 3, and the length along the folding line 11 of the bottom surface 3 that must be folded when the bottom is raised is also small. As a result, it is extremely easy to raise the bottom in combination with shortening of the folding portions of the long side surface 4 and the bottom surface 3 (regions sandwiched between the folding lines 7 and 11).

なお、図１８に示すように、補助切込線３３を設けた際に、補助切込線１３を廃してもかまわない。この場合、長側面４において、切込み３３により分断されて短側面５側に残る三角形状の部分（上記切込み１３，３３で囲まれた三角形状の折込片に対応する部分）は、短側面５の下部５ａとともに折り込まれる。 As shown in FIG. 18, when the auxiliary cut line 33 is provided, the auxiliary cut line 13 may be eliminated. In this case, on the long side surface 4, the triangular portion that is divided by the cut 33 and remains on the short side surface 5 side (the portion corresponding to the triangular folded piece surrounded by the cuts 13 and 33) It is folded together with the lower part 5a.

以上、本発明を実施するための形態について例示したが、本発明の実施形態は上述したものに限られず、本発明の趣旨を逸脱しない範囲で適宜変更等してもよい。 As mentioned above, although the form for implementing this invention was illustrated, embodiment of this invention is not restricted to what was mentioned above, You may change suitably etc. in the range which does not deviate from the meaning of this invention.

例えば、収納箱は、切込線の形成や長側面及び短側面の折込み、底面の押上げを可能とするものであればどのようなものでもよく、その材質を紙ではなく薄いプラスチックとしてもよい。 For example, the storage box may be anything as long as it allows the formation of score lines, the folding of long and short sides, and the lifting of the bottom, and the material may be a thin plastic instead of paper. .

また、切込線９を底面３及び長側面４の長手方向に沿って１箇所のみに設けるのではなく、２箇所以上に設けてもよいし、補助切込線１４を長辺３ａの端部３ｃから底面３と長側面４との交線に沿って設けるのではなく、底面３と短側面５との交線に沿って設けてもよい。 In addition, the cut line 9 may be provided at two or more places along the longitudinal direction of the bottom face 3 and the long side face 4, and may be provided at two places or more, and the auxiliary cut line 14 is provided at the end of the long side 3a. Instead of being provided along the intersection line between the bottom surface 3 and the long side surface 3 from 3c, it may be provided along the intersection line between the bottom surface 3 and the short side surface 5.

さらに、底上げ時に折込片を収納箱の内側ではなく外側に折り込んでもよいが、中空内部の側に折り曲げた方が長側面の裏面に押し戻される等して開口を塞ぐように復元しやすい場合には、その方が密閉性を保つ（通気性を抑える）上では望ましいことは上記のとおりである。 In addition, the folded piece may be folded outside the storage box instead of inside the storage box when raising the bottom, but when it is easier to restore the closed side so that it is pushed back to the back side of the long side when folded into the hollow interior side As described above, it is desirable to maintain the airtightness (suppress air permeability).

本発明は、積層状態のシート状の収納物で、上層のシートから順次取り出されて残量が減っていくものを収納する場合であれば、用途を問わず利用することができる。 The present invention can be used for any purpose as long as it is a stacked sheet-like stored item that is sequentially taken out from the upper layer sheet and the remaining amount decreases.
