Abstract

To eliminate or reduce warpage of a rectangular bottom surface without depending on improvement in rigidity.SOLUTION: A self-standing thin rectangular parallelepiped carton 1B is formed of a paper pattern having a panel constitution in which a long side of a rectangular bottom panel 31, long sides of rectangular left and right side face panels 11 and 13 narrower than a front panel 12 and a long side of a rectangular back panel 14 are consecutively connected to a lower edge of a short side of the rectangular front panel 12, both side edges of the long side of the front panel 12 and a side edge of the left side panel 13 respectively. In the outer bottom face panel 31 is formed an inclined recessed surface 31A inclined from one long side toward the other long side of the outer bottom face panel 31.SELECTED DRAWING: Figure 2

Description

この発明は自立性の高い，すなわち安定して自立させることができる薄型直方体カートンに関する。   The present invention relates to a thin rectangular parallelepiped carton having high self-reliance, that is, stable self-standing.

長方形の底面を備える薄型直方体カートンは倒れやすく，これを倒れにくくするために外向きに短くのびる脚部を形成することが考えられている（特許文献１）。特許文献１に記載のものは，カートンの前板部と底板部の境界において底板部に入り込む切欠きが形成されており，この切欠きを前脚部として利用する。底面に穴が開くので内容物の保護に欠ける。   It has been considered that a thin rectangular parallelepiped carton having a rectangular bottom is prone to fall, and in order to make it difficult to fall it, it is considered to form an outwardly extending short leg (Patent Document 1). In the case described in Patent Document 1, a notch is formed in the bottom plate portion at the boundary between the front plate portion and the bottom plate portion of the carton, and this notch is used as a front leg portion. Since the hole is in the bottom, it lacks the protection of the contents.

特許文献２は，長方形の底板面に，短辺に平行な方向の罫線を入れたものを開示する。長方形の底面を備える薄型直方体カートンの底面は，側方から見て外方に向かって弧状に反りがちであるが，上記罫線によって底板面の上記反りに対する剛性を向上させることができる。しかしながら，反りに完全に打ち勝つほどに剛性を向上させるのは難しい。   Patent Document 2 discloses a bottom plate surface of a rectangle in which ruled lines in a direction parallel to the short sides are inserted. The bottom surface of the thin rectangular parallelepiped carton having a rectangular bottom surface tends to bow in an arc shape outward when viewed from the side, but the above-mentioned ruled lines can improve the rigidity against the above-mentioned warp of the bottom plate surface. However, it is difficult to improve the rigidity so that the warpage is completely overcome.

この発明は，剛性向上に頼らずに長方形の底面の反りを無くすまたは軽減することを目的とする。   An object of the present invention is to eliminate or reduce warpage of a rectangular bottom without relying on rigidity improvement.

この発明はまた，長期間にわたって安定した自立を維持することができるようにすることを目的とする。   Another object of the present invention is to make it possible to maintain stable independence over a long period of time.

この発明による自立性薄型直方体カートンは，長方形の正面パネルの短辺下縁に長方形の外側底面パネルの長辺が，上記正面パネルの長辺両側縁に上記正面パネルより幅狭の長方形の左右の側面パネルの長辺が，上記左右の側面パネルのいずれかの側縁に長方形の背面パネルの長辺が，それぞれ連設されているパネル構成を有する型紙からつくられるものであって，上記外側底面パネルに，外側底面パネルの一方の長辺から他方の長辺に向けて，または一方の短辺から他方の短辺に向けて傾斜する傾斜凹面が形成されているものである。   In the self-supporting thin rectangular parallelepiped carton according to the present invention, the lower side of the short side of the rectangular front panel and the long side of the rectangular outer bottom panel are smaller than the width of the front panel of the rectangular side. The long side of the side panel is made from a template having a panel configuration in which the long side of the rectangular back panel is connected to either side edge of the left and right side panels, The panel is formed with an inclined concave surface which is inclined from one long side to the other long side of the outer bottom panel or from one short side to the other short side.

型紙を折ることで立体的につくられるカートンは，紙が持つ弾性（反発力）によって，折られる前の状態に戻ろうとする力がパネルに働く。正面パネルに連設された外側底面パネルは内向きに折られるので，外向きの力が生じがちである。この発明によると，上記外側底面パネルに，外側底面パネルの一方の長辺から他方の長辺に向けて，または一方の短辺から他方の短辺に向けて傾斜する傾斜凹面が形成されているので，紙の反発力によって外側底面パネルに外向きの力が働いても，外方湾曲底面を接地面（平坦面）に接しにくくすることができ，薄型直方体カートンの自立の不安定化を防止または軽減することができる。   A carton made in three dimensions by folding a template works on the panel to return to its unfolded state by the resiliency of the paper. Since the outer bottom panel connected to the front panel is folded inward, an outward force tends to occur. According to the present invention, the outer bottom panel is formed with an inclined concave surface which is inclined from one long side of the outer bottom panel to the other long side or from one short side to the other short side. Therefore, even if an outward force acts on the outer bottom panel due to paper repulsion, the outer curved bottom can be made less likely to contact the ground surface (flat surface), preventing the instability of the thin rectangular parallelepiped carton Or can be mitigated.

自立性薄型直方体カートンの外側底面パネルは長方形であり，側方から見て外方に向かって弧状に反りがちであるので，傾斜凹面は外側底面パネルの長手方向にのびるように形成するのが好ましい。もっとも，傾斜凹面を複数に分け，複数の傾斜凹面を外側底面パネルの長手方向に並べてまたは短手方向に並べて形成してもよい。   Since the outer bottom panel of the self-supporting thin rectangular box is rectangular and tends to bow in an arc when viewed from the side, it is preferable to form the inclined concave surface so as to extend in the longitudinal direction of the outer bottom panel . However, the inclined concave surface may be divided into a plurality, and the plurality of inclined concave surfaces may be formed side by side in the longitudinal direction of the outer bottom panel or in the lateral direction.

傾斜凹面の傾斜方向について，外側底面パネルの一方の長辺から他方の長辺に向けて次第に深さが深くなるように形成してもよいし，外側底面パネルの一方の短辺から他方の短辺に向けて次第に深さが深くなるように形成してもよい。   In the inclined direction of the inclined concave surface, the depth may be gradually increased from one long side to the other long side of the outer bottom panel, or from the short side of the outer bottom panel to the other short side. You may form so that the depth may become deep gradually toward a side.

好ましくは，上記背面パネルの短辺下縁に長方形の内側底面パネルの長辺が連設されており，内側底面パネルについても，外側底面パネルの一方の長辺から他方の長辺に向けて，または一方の短辺から他方の短辺に向けて傾斜する傾斜凹面が形成されている。   Preferably, a long side of a rectangular inner bottom panel is connected to a lower edge of a short side of the back panel, and the inner bottom panel is also directed from one long side of the outer bottom panel to the other long side, Or the inclined concave surface which inclines toward the other short side from one short side is formed.

図１は第１実施例の薄型直方体カートンの展開図を示している。図２は第１実施例の薄型直方体カートンを底面がわから見た斜視図である。図３は図２のIII−III線に沿う薄型直方体カートンの下部の端面図である。   FIG. 1 shows a developed view of the thin rectangular parallelepiped carton of the first embodiment. FIG. 2 is a perspective view of the thin rectangular parallelepiped carton of the first embodiment seen from the bottom. 3 is an end view of the lower portion of the thin rectangular parallelepiped carton taken along the line III-III of FIG.

図１の展開図１Ａは薄型直方体カートン１Ｂ（図２，図３）を形成する厚紙の型紙を示しており，薄型直方体カートン１Ｂに組み立てたときの外側となる面を見たものである。一点鎖線は薄型直方体カートン１Ｂを組み立てるときに山折りにされる折り線を示している。折り曲げを容易にするために，この一点鎖線に沿って押し罫加工が施される。   The developed view 1A of FIG. 1 shows a cardboard template forming the thin rectangular parallelepiped carton 1B (FIGS. 2 and 3), and is a view of the outer surface when assembled in the thin rectangular parallelepiped carton 1B. The alternate long and short dash lines indicate folding lines that are mountain-folded when assembling the thin rectangular parallelepiped carton 1B. In order to facilitate bending, crease processing is performed along the alternate long and short dash line.

図１に示すように型取り（型抜き）された型紙１Ａを折り曲げかつ必要箇所を接着（糊付け）することによって図２〜図３に示す薄型直方体カートン１Ｂがつくられる。   As shown in FIG. 1, the thin rectangular parallelepiped carton 1B shown in FIGS. 2 to 3 is produced by bending the molded paper 1A and bonding (gluing) the necessary parts.

図１を参照して，右側面パネル11，正面パネル12，左側面パネル13，背面パネル14および糊代パネル15が横向きに連設されている。右側面パネル11，正面パネル12，左側面パネル13，背面パネル14および糊代パネル15は，いずれもその幅（横方向の長さ）に比べて高さ（縦方向の長さ）が高く，長方形の形状を持つ。   Referring to FIG. 1, a right side panel 11, a front panel 12, a left side panel 13, a back panel 14 and a glue margin panel 15 are continuously provided in a lateral direction. The right side panel 11, the front panel 12, the left side panel 13, the back panel 14 and the glue margin panel 15 are all higher in height (longitudinal length) than their width (lateral length), It has a rectangular shape.

正面パネル12の上縁に外側天面パネル21が連設され，背面パネル14の上縁に内側天面パネル22が連設されている。正面パネル12の下縁に外側底面パネル31が連設され，背面パネル14の下縁に内側底面パネル32が連設されている。左右の側面パネル11，13の上下縁にはフラップ41が連設されている。   An outer top panel 21 is connected to the upper edge of the front panel 12, and an inner top panel 22 is connected to the upper edge of the rear panel 14. An outer bottom panel 31 is connected to the lower edge of the front panel 12, and an inner bottom panel 32 is connected to the lower edge of the back panel 14. The flaps 41 are connected to the upper and lower edges of the left and right side panels 11 and 13 respectively.

正面パネル12とその下縁に連設された外側底面パネル31の境界，および背面パネル14とその下縁に連設された内側底面パネル32の境界にはミシン目（間隔をあけて形成された複数の孔の列）Ｍが形成されている。ミシン目Ｍは厚紙を折ったときの反発（折られる前の姿勢に戻ろうとする力）を軽減するために形成されている。ミシン目に代えてハーフカットを形成してもよい。   Perforations are formed at the boundary between the front panel 12 and the outer bottom panel 31 connected to the lower edge thereof, and at the boundary between the back panel 14 and the inner bottom panel 32 connected to the lower edge thereof. A plurality of rows of holes) M are formed. The perforations M are formed to reduce the repulsion (force to return to the posture before being folded) when the cardboard is broken. The perforations may be replaced by half cuts.

外側底面パネル31および内側底面パネル32の表面（外面）に傾斜凹面31Ａ，32Ａが形成されている。   Inclined concave surfaces 31A and 32A are formed on the surfaces (outer surfaces) of the outer bottom panel 31 and the inner bottom panel 32, respectively.

外側底面パネル31に形成された傾斜凹面31Ａは，外側底面パネル31の長手方向（左右の短辺同士を結ぶ向き）に形成され，正面パネル12との境界（ミシン目Ｍ）から外側底面パネル31の先端縁部に向かって次第に深くなる傾斜を持つ。内側底面パネル32に形成された傾斜凹面32Ａは，内側底面パネル32の長手方向（左右の短辺同士を結ぶ向き）に形成され，内側底面パネル32の先端縁部から背面パネル14との境界（ミシン目Ｍ）に向かって次第に深くなる傾斜を持つ。傾斜凹面31Ａ，32Ａのもっとも深い箇所の深さは，紙厚によるが，たとえば紙厚が 400μｍであれば，100μｍ〜200μｍ程度とされる。傾斜凹面31Ａ，32Ａは，外側，内側底面パネル31，32の表面（外面）に傾斜凸面を有する型を押し付けることで形成される。もっとも，通常の罫線をつくる罫線刃を押し型に用いても傾斜凹面31Ａ，32Ａは形成可能であり，この場合には押し型を受ける面板に傾斜凹面を有するものが用いられる。   The inclined concave surface 31A formed on the outer bottom panel 31 is formed in the longitudinal direction of the outer bottom panel 31 (direction connecting the left and right short sides), and from the border (perforation M) with the front panel 12 to the outer bottom panel 31. It has a slope that gets progressively deeper towards the tip edge of the. The inclined concave surface 32A formed on the inner bottom panel 32 is formed in the longitudinal direction (direction connecting the left and right short sides) of the inner bottom panel 32, and the boundary between the tip edge of the inner bottom panel 32 and the back panel 14 It has a slope which becomes deeper gradually toward the perforation M). Although the depth of the deepest portion of the inclined concave surfaces 31A and 32A depends on the paper thickness, for example, if the paper thickness is 400 μm, it is about 100 μm to 200 μm. The inclined concave surfaces 31A, 32A are formed by pressing a mold having an inclined convex surface on the surface (outer surface) of the outer and inner bottom panels 31, 32. However, the inclined concave surfaces 31A and 32A can be formed even if a ruled line blade for forming a usual crease is used as a pressing die, in which case, the face plate which receives the pressing die has an inclined concave surface.

図３を参照して，外側，内側底面パネル31，32の傾斜凹面31Ａ，32Ａは，外側，内側底面パネル31，32が重ねあわされたときに重なり合う箇所（範囲）に形成される。外側，内側底面パネル31，32の外面に形成される傾斜凹面31Ａ，32Ａに対応して，外側，内側底面パネル31，32の内面には傾斜凸面が形成される。   Referring to FIG. 3, the inclined concave surfaces 31A and 32A of the outer and inner bottom panels 31 and 32 are formed at overlapping portions (ranges) when the outer and inner bottom panels 31 and 32 are overlapped. Corresponding to the inclined concave surfaces 31A and 32A formed on the outer surfaces of the outer and inner bottom panels 31 and 32, inclined convex surfaces are formed on the inner surface of the outer and inner bottom panels 31 and 32, respectively.

薄型直方体カートン１Ｂは次のようにして組み立てられる。すなわち，左側面パネル13と背面パネル14の境界で型紙１Ａを折畳み，正面パネル12と右側面パネル11の境界も折畳む。重なり合う糊代パネル15と右側面パネル11とを接着して筒状とし，その後に隣接するパネル間の角度が直角となるように起函する。上面および下面が開口する角筒が作られる。   The thin rectangular parallelepiped carton 1B is assembled as follows. That is, the paper pattern 1A is folded at the boundary between the left side panel 13 and the back panel 14, and the boundary between the front panel 12 and the right side panel 11 is also folded. The overlapping paste margin panel 15 and the right side panel 11 are adhered to form a tubular shape, and then raised so that the angle between the adjacent panels becomes a right angle. A square tube is created with open top and bottom surfaces.

左右の側面パネル11，13の下縁に連設されたフラップ41を内向きに直角に折り，次に背面パネル14の下縁に連設された内側底面パネル32を内向きに直角に折り，最後に正面パネル12の下縁に連設された外側底面パネル31を内向きに直角に折り，外側底面パネル31の内面と内側底面パネル32の外面とを接着する。角筒の底面が閉じられる。   Fold the flaps 41 connected to the lower edge of the left and right side panels 11 and 13 at a right angle inward, and then fold the inner bottom panel 32 connected to the lower edge of the back panel 14 at a right angle inward; Finally, the outer bottom panel 31 continuously connected to the lower edge of the front panel 12 is folded inward at a right angle to bond the inner surface of the outer bottom panel 31 and the outer surface of the inner bottom panel 32. The bottom of the square tube is closed.

開口する上面から角筒内に，医薬品，化粧品，菓子等の内容物が入れられ，その後に上面開口も閉じられる。下面を閉じる工程と同様に，左右の側面パネル11，13の上縁のフラップ41を内向きに直角に折り，背面パネル14の上縁の内側天面パネル22を内向きに直角に折る。最後に正面パネル12の上縁の外側天面パネル21を内向きに直角に折り，外側天面パネル21の内面と内側天面パネル22の外面を接着する。角筒の天面が閉じられ，薄型直方体カートン１Ｂが完成する。   Contents such as medicines, cosmetics, confectionery, etc. are put into the square tube from the open upper surface, and then the upper surface opening is also closed. Similar to the process of closing the lower surface, the flaps 41 on the upper edge of the left and right side panels 11 and 13 are folded inward at a right angle, and the inner top panel 22 of the upper edge of the back panel 14 is folded at a right angle inward. Finally, the outer top panel 21 at the upper edge of the front panel 12 is folded at a right angle inward to bond the inner surface of the outer top panel 21 and the outer surface of the inner top panel 22. The top surface of the square tube is closed to complete the thin rectangular parallelepiped carton 1B.

図２および図３を参照して，薄型直方体カートン１Ｂの底面を構成する外側，内側底面パネル31，32の外面の傾斜凹面31Ａ，32Ａは内方に凹んでいるので，傾斜凹面31Ａ，32Ａは接地せず，傾斜凹面31Ａ，32Ａが形成されていない傾斜凹面31Ａ，32Ａを取り囲む範囲が接地面となり（接地するのは外側底面パネル31の傾斜凹面31Ａを取り囲む範囲），ここで薄型直方体カートン１Ｂは支持されることになる。   Referring to FIGS. 2 and 3, since the inclined concave surfaces 31A and 32A of the outer surfaces of the outer and inner bottom panels 31 and 32 constituting the bottom surface of the thin rectangular parallelepiped carton 1B are recessed inward, the inclined concave surfaces 31A and 32A are The area surrounding the inclined concave surfaces 31A and 32A without the ground and the inclined concave surfaces 31A and 32A not formed is the ground plane (the ground is the area surrounding the inclined concave surface 31A of the outer bottom panel 31). Will be supported.

型紙を折ることで立体的につくられるカートンは，紙が持つ弾性（反発力）によって，折られる前の状態に戻ろうとする力がパネルに働く。正面パネル12の下縁に連設された外側底面パネル31は内向きに折られるので，外向きの力が生じる。背面パネル14の下縁に連設された内側底面パネル32も内向きに折られるので，外向きの力が生じる。外向きの力は正面パネル12と外側底面パネル31の境界，および背面パネル14と内側底面パネル32の境界に働く。外側，内側底面パネル31，32は接着されているので，側方からみて外方（下方）に反る向きに湾曲を生じがちである。   A carton made in three dimensions by folding a template works on the panel to return to its unfolded state by the resiliency of the paper. Since the outer bottom panel 31 continuously connected to the lower edge of the front panel 12 is folded inward, an outward force is generated. Since the inner bottom panel 32 connected to the lower edge of the back panel 14 is also folded inward, an outward force is generated. The outward force acts on the boundary between the front panel 12 and the outer bottom panel 31 and the boundary between the back panel 14 and the inner bottom panel 32. Because the outer and inner bottom panels 31, 32 are bonded, they tend to bow in a direction that bows outward (downward) when viewed from the side.

ここで，外側，内側底面パネル31，32には傾斜凹面31Ａ，32Ａが形成されているので，正面パネル12と外側底面パネル31の境界，および背面パネル14と内側底面パネル32の境界に働く外向きの紙の反発力は，傾斜凹面31Ａ，32Ａの範囲に伝わらないまたは伝わりにくくなる。また，傾斜凹面31Ａ，32Ａが外方に湾曲しても，接地面（傾斜凹面31Ａ，32Ａを取り囲む範囲）を大きく超えて外方に突出しにくく，したがって外方湾曲底面が平坦面に接して薄型直方体カートン１Ｂを不安定にすることがない。   Here, since the inclined concave surfaces 31A and 32A are formed in the outer and inner bottom panels 31, 32, the outer working on the boundary between the front panel 12 and the outer bottom panel 31, and the boundary between the rear panel 14 and the inner bottom panel The repulsive force of the oriented paper will not be transmitted to the range of the inclined concave surfaces 31A, 32A or will not be transmitted. In addition, even if the inclined concave surfaces 31A and 32A are curved outward, it is difficult to project outward greatly beyond the ground contact surface (the range surrounding the inclined concave surfaces 31A and 32A). There is no instability of the rectangular parallelepiped carton 1B.

さらに，外側，内側底面パネル31，32に形成される凹面を斜面とすることで，凸凹部が滑らかになり，印刷表示部を阻害することなく，意匠性に優れる。また，段差の開始部から徐々に滑らかに平らになるので疑似的（相対的）に断面が階段状になり，上記境界に働く曲がり反発力を効果的に抑制することができる。   Further, by forming the concaves formed on the outer and inner bottom panels 31 and 32 as inclined surfaces, the convex and concave portions become smooth, and the design is excellent without obstructing the printing display portion. Also, since the surface gradually becomes smooth and flat from the start of the step, the cross section becomes pseudo-stepwise (relatively) stepped, and it is possible to effectively suppress the bending repulsive force acting on the boundary.

また薄型直方体カートン１Ｂは切込みを用いて脚部を形成するものではないので，切込みによる隙間（孔）ができることもなく，カートン１Ｂ内への塵埃の侵入を防止することができる。   Further, since the thin rectangular parallelepiped carton 1B does not use the incisions to form the leg portions, it is possible to prevent the entry of dust into the carton 1B without forming gaps (holes) by the incisions.

傾斜凹面は少なくとも外側底面パネル31に形成すればよく，内側底面パネル32に形成する必要は必ずしもない。もっとも，内側底面パネル32にも傾斜凹面を形成するのが好ましい。   The inclined concave surface may be formed at least on the outer bottom panel 31, and is not necessarily formed on the inner bottom panel 32. However, it is preferable to form an inclined concave surface on the inner bottom panel 32 as well.

図４および図５は第２実施例を示すもので，図４は薄型直方体カートンを形成する厚紙の型紙２Ａを示している。図５は型紙２Ａから形成される薄型直方体カートン２Ｂを底面がわから示す斜視図である。図１および図２に示す型紙１Ａおよび薄型直方体カートン１Ｂとは，外側，内側底面パネル31，32に形成されている傾斜凹面31Ｂ，32Ｂが，外側，内側底面パネル31，32の短辺同士を結ぶ全体に（端から端まで）形成されている点が異なる。傾斜凹面31Ｂ，32Ｂを挟む，正面パネル12がわおよび背面パネル14がわのそれぞれにおいて長手方向にのびる領域において，薄型直方体カートン１Ｂは支持される。正面パネル12がわおよび背面パネル14がわのそれぞれにおいて支持されることによって，薄型直方体カートン１Ｂは安定して自立する。   FIGS. 4 and 5 show a second embodiment, and FIG. 4 shows a cardboard template 2A forming a thin rectangular parallelepiped carton. FIG. 5 is a perspective view showing the bottom of a thin rectangular parallelepiped carton 2B formed from the template 2A. In the template 1A and the thin rectangular parallelepiped carton 1B shown in FIGS. 1 and 2, the inclined concave surfaces 31B and 32B formed on the outer and inner bottom panels 31, 32 are the short sides of the outer and inner bottom panels 31, 32. The difference is that the whole is formed (end to end). The thin rectangular parallelepiped carton 1B is supported in the region in which the front panel 12 and the back panel 14 extend in the longitudinal direction on both sides of the inclined concave surfaces 31B and 32B. By supporting the front panel 12 with the back panel 14 at each of the walls, the thin rectangular parallelepiped carton 1B is stably and self-supporting.

図６は第３実施例の薄型直方体カートンを形成する型紙３Ａを示している。図１に示す第１実施例の薄型直方体カートンを形成する型紙１Ａとは，外側，内側底面パネル31，32のそれぞれに，長手方向にのびる傾斜凹面31Ａ１，31Ａ２，32Ａ１，32Ａ２が，上下に並んで（正面と背面を結ぶ方向に）間隔をあけて形成されている点が異なる。また，合計４つの傾斜凹面31Ａ１，31Ａ２，32Ａ１，32Ａ２が，いずれも外側，内側底面パネル31，32の先端縁部から正面，背面パネル12，14との境界（ミシン目Ｍ）に向かって次第に深くなる傾斜を持つ点が異なる。   FIG. 6 shows a paper pattern 3A forming the thin rectangular parallelepiped carton of the third embodiment. In the template 1A forming the thin rectangular parallelepiped carton of the first embodiment shown in FIG. 1, the inclined concave surfaces 31A1, 31A2, 32A1, 32A2 extending in the longitudinal direction are arranged vertically on the outer and inner bottom panels 31, 32 respectively. The difference is that they are formed spaced apart (in the direction connecting the front and back). In addition, a total of four inclined concave surfaces 31A1, 31A2, 32A1, and 32A2 gradually increase from the leading edge of the outer and inner bottom panels 31, 32 toward the boundary with the front and rear panels 12, 14 (perforation M). The difference is that they have a deeper slope.

正面パネル12と背面パネル14とを結ぶ方向に２つの傾斜凹面を並べて形成することで，外側，内側底面パネル31，32に外向きにかかる力を２段階に防ぐことができる。   By forming two inclined concaves side by side in the direction connecting the front panel 12 and the back panel 14, the force applied to the outside and the inside bottom panels 31 and 32 can be prevented in two stages.

外側底面パネル31に形成された傾斜凹面31Ａ１，31Ａ２と，内側底面パネル32に形成された傾斜凹面32Ａ１，32Ａ２は同じ向き（ミシン目Ｍに向かう方向に次第に深くなる向き）の傾斜であるので，外側底面パネル31と内側底面パネル32を重ね合わせたときに凹凸が完全には重なり合わないものの，傾斜凹面の深さは上述したように100μｍ〜200μｍ程度であるので，接着剤等によって外側底面パネル31の内面と内側底面パネル32の外面の間を埋めつつこれらを接着することができる。傾斜凹面の方向（外側，内側底面パネル31，32の先端縁部に向けて浅くするか深くするか）は任意に設計することができる。もっとも，紙の反発力によって外側，内側底面パネル31，32に生じる外向きの力は，正面パネル12と外側底面パネル31の境界，および背面パネル14と内側底面パネル32の境界に働くので，少なくとも１つの傾斜凹面は，この境界に向けて傾斜が深くなる向きに形成するのが好ましい。   Since the inclined concave surfaces 31A1 and 31A2 formed on the outer bottom surface panel 31 and the inclined concave surfaces 32A1 and 32A2 formed on the inner bottom surface panel 32 are inclined in the same direction (direction in which they are gradually deepened in the direction toward the perforation M), Although the unevenness does not completely overlap when the outer bottom panel 31 and the inner bottom panel 32 are overlapped, the depth of the inclined concave is about 100 μm to 200 μm as described above. These can be adhered while filling in between the inner surface of 31 and the outer surface of the inner bottom panel 32. The direction of the inclined concave surface (whether it is shallow or deep toward the leading edge of the outer and inner bottom panels 31, 32) can be designed arbitrarily. However, the outward force generated on the outer and inner bottom panels 31 and 32 by the repulsive force of the paper acts on the boundary between the front panel 12 and the outer bottom panel 31 and the boundary between the back panel 14 and the inner bottom panel 32. One inclined concave surface is preferably formed in a direction in which the inclination becomes deeper toward this boundary.

第３実施例の傾斜凹面31Ａ１，31Ａ２，32Ａ１，32Ａ２についても，外側，内側底面パネル31，32の短辺同士を結ぶ全体に（端から端まで）形成してもよい（図１，図２に示す傾斜凹面31Ａ，31Ｂと同様の関係）。   The inclined concave surfaces 31A1, 31A2, 32A1 and 32A2 of the third embodiment may also be formed on the entire short sides of the outer and inner bottom panels 31 and 32 (from end to end) (FIGS. 1 and 2) The same relationship as the inclined concave surfaces 31A and 31B shown in FIG.

図７および図８は第４実施例を示すもので，図７は薄型直方体カートンを形成する型紙４Ａを示している。図８は型紙４Ａから形成される薄型直方体カートン４Ｂを底面がわから示す斜視図である。   7 and 8 show a fourth embodiment, and FIG. 7 shows a pattern 4A forming a thin rectangular parallelepiped carton. FIG. 8 is a perspective view showing the bottom of a thin rectangular parallelepiped carton 4B formed from the template 4A.

外側底面パネル31に，傾斜凹面31Ｃ１と傾斜凹面31Ｃ２とが間隔をあけて長手方向に並んで形成されている。外側底面パネル31の左側に形成されている傾斜凹面31Ｃ１は，外側底面パネル31の左短辺に向かって次第に深さが深くなる傾斜を持つ。外側底面パネル31の右側に形成されている傾斜凹面31Ｃ２は，外側底面パネル31の右短辺に向かって次第に深さが深くなる傾斜を持つ。内側底面パネル32も同様であり，傾斜凹面32Ｃ１と傾斜凹面32Ｃ２とが間隔をあけて長手方向に並んで形成されており，内側底面パネル32の左側に形成されている傾斜凹面32Ｃ１は内側底面パネル32の左短辺に向かって次第に深さが深くなる傾斜を持ち，内側底面パネル32の右側に形成されている傾斜凹面32Ｃ２は，内側底面パネル32の右短辺に向かって次第に深さが深くなる傾斜を持つ。このように外側，内側底面パネル31，32の短辺同士を結ぶ方向の傾斜を有する凹面を形成することによっても，薄型直方体カートン４Ｂの自立安定性を向上させることができる。 Outside the bottom panel 31, an inclined concave surface 31C 1 and inclined concave 31C 2 are formed side by side in the longitudinal direction at intervals. Inclined concave 31C 1 which is formed on the left side of the outer bottom panel 31 has a gradually depth increases inclined toward the left short side of the outer bottom panel 31. Inclined concave 31C 2 formed on the right side of the outer bottom panel 31 has a gradually depth increases inclined toward the right short side of the outer bottom panel 31. Inner bottom panel 32 is also similar, are formed side by side in the longitudinal direction and the inclined concave 32C 1 and inclined concave 32C 2 are spaced, inclined concave 32C 1 which is formed on the left side of the inner bottom panel 32 It has gradually depth increases inclined toward the left short side of the inner bottom panel 32, inclined concave 32C 2 formed on the right side of the inner bottom panel 32 gradually toward the right short side of the inner bottom panel 32 It has a slope that deepens the depth. The self-supporting stability of the thin rectangular parallelepiped carton 4B can also be improved by forming a concave having an inclination in a direction connecting the short sides of the outer and inner bottom panels 31 and 32 in this manner.

図９および図１０は第５実施例を示すもので，図９は薄型直方体カートンを形成する型紙５Ａを示している。図１０は型紙５Ａから形成される薄型直方体カートン５Ｂを底面がわから示す斜視図である。   9 and 10 show a fifth embodiment, and FIG. 9 shows a pattern 5A forming a thin rectangular parallelepiped carton. FIG. 10 is a perspective view showing the bottom of the thin rectangular parallelepiped carton 5B formed from the template 5A.

外側底面パネル31に，傾斜凹面31Ｄ１と傾斜凹面31Ｄ２と傾斜凹面31Ｄ３が間隔をあけて長手方向に並んで形成されている。傾斜凹面31Ｄ１，31Ｄ２，31Ｄ３は，いずれも外側底面パネル31の長辺同士を結ぶ方向に傾斜しているが，その向きが，両端の傾斜凹面31Ｄ１と傾斜凹面31Ｄ３とについては正面パネル12との境界（ミシン目Ｍ）から外側底面パネル31の先端部に向けて次第に深くなる方向に傾斜しているのに対し，これらに挟まれた傾斜凹面31Ｄ２については外側底面パネル31の先端部から正面パネル12との境界（ミシン目Ｍ）に向けて次第に深くなる方向に傾斜している。 Outside the bottom panel 31, inclined concave 31D 1 an inclined concave surface 31D 2 and the inclined concave 31D 3 are formed side by side in the longitudinal direction at intervals. The inclined concave surfaces 31D 1 , 31D 2 and 31D 3 are all inclined in the direction connecting the long sides of the outer bottom panel 31, but the directions thereof are the inclined concave surfaces 31D 1 at both ends and the inclined concave surfaces 31D 3. The outer bottom panel 31 is inclined in the direction of becoming deeper gradually from the boundary (perforation M) with the front panel 12 toward the tip of the outer bottom panel 31, while the outer bottom panel 31 for the inclined concave surface 31 D 2 sandwiched therebetween. Are inclined in the direction of becoming deeper gradually from the tip of the head to the boundary (perforation M) with the front panel 12.

内側底面パネル32については，外側底面パネル31と内側底面パネル32とを重ね合わせたときに傾斜凹面同士を重ね合わせることができるようにするために，両端の傾斜凹面32Ｄ１と傾斜凹面32Ｄ３については内側底面パネル32の先端部から背面パネル14との境界に向けて次第に深くなる方向に傾斜しており，これらに挟まれた傾斜凹面32Ｄ２は背面パネル14との境界から内側底面パネル32の先端部に向けて次第に深くなる方向に傾斜している。 The inner bottom panel 32, in order to be able to superimpose inclined concave together when superposing the outer bottom panel 31 and the inner bottom panel 32, the inclined concave 32D 1 and the inclined concave surface 32D 3 at both ends Is inclined in the direction of getting deeper from the tip of the inner bottom panel 32 toward the boundary with the back panel 14, and the inclined concave surface 32 D 2 sandwiched therebetween is from the boundary with the back panel 14 It inclines in the direction which becomes deeper gradually toward the tip.

上述したように，正面パネル12と外側底面パネル31の境界，および背面パネル14と内側底面パネル32の境界に，外側，内側底面パネル31，32を外方に湾曲させる力が生じるので，正面パネル12と外側底面パネル31の境界，および背面パネル14と内側底面パネル32の境界のそれぞれに対してバランスよく，外方に湾曲させる力を低減させる構造を持たせるのが好ましい。上述のように外側，内側底面パネル31，32のそれぞれに，傾斜方向が逆向きの複数の傾斜凹面を形成しておくことで，このバランスをとることができる。   As described above, the force that causes the outer and inner bottom panels 31, 32 to curve outward is generated at the boundary between the front panel 12 and the outer bottom panel 31, and at the boundary between the back panel 14 and the inner bottom panel 32. It is preferable to have a structure that reduces the force of curving outward in a well-balanced manner with respect to each of the boundary between the outer bottom panel 31 and the outer bottom panel 31 and the boundary between the back panel 14 and the inner bottom panel 32. This balance can be achieved by forming a plurality of inclined concave surfaces whose directions of inclination are opposite to each other on the outer and inner bottom panels 31 and 32 as described above.

FIG. 12 is a perspective view showing the bottom of a thin rectangular parallelepiped carton 6B formed from the template 6A.

傾斜凹面31Ｅ，32Ｅはいずれも外側，内側底面パネル31，32の長手方向に形成されており，外側，内側底面パネル31，32のそれぞれの左右の端部に，左右短辺に向かってしたがって次第に深さが浅くなる傾斜を持つものである。このような傾斜凹面31Ｅ，32Ｅによっても薄型直方体カートン６Ｂの自立安定性が向上する。   The inclined concave surfaces 31E, 32E are both formed in the longitudinal direction of the outer and inner bottom panels 31, 32, and are gradually extended toward the left and right sides of the outer, inner bottom panels 31, 32, respectively, toward the left and right sides. It has a slope that is shallow in depth. The self-supporting stability of the thin rectangular parallelepiped carton 6B is also improved by such inclined concave surfaces 31E and 32E.
