Description

本発明は、ロール状に巻き込んだクッキングペーパーやペーパータオル等のロールシートを収納する直方体形状の紙箱であって、開閉が可能なシート引き出し口を紙箱正面に有するロールシート収納紙箱に関する。特に、本発明は、ロールシートの引き出し抵抗が少なく、均一幅で水平に引き出すことができる開口部を紙箱前面に有するロールシート収納紙箱に関する。 The present invention relates to a cuboid-shaped paper box for storing roll sheets such as cooking paper and paper towels wound in a roll shape, and relates to a roll sheet storage paper box having a sheet drawer opening that can be opened and closed on the front side of the paper box. In particular, the present invention relates to a roll sheet storage paper box having an opening on the front side of the paper box that has a small pull-out resistance of the roll sheet and can be pulled out horizontally with a uniform width.

ロール状に巻き込んだクッキングペーパーやペーパータオル等のロールシートを収納した直方体形状の紙箱の天面から正面にかけて切り離し用の不連続切断線を設けて開閉可能なロールシート取り出し口を形成するタイプのロールシート収納箱として、収納ロールシートの取り出し易さを向上させたもの（特許文献１、特許文献２）、収納ロールシートの切断機構を改善したもの（特許文献３）、トップオープン方式の開閉紙箱の開閉部分のリクローズ性を改善したもの（特許文献４）などのように収納ロールシートの開閉可能な取り出し口の改善に関する提案は多数なされている。 Roll sheet of the type that forms a roll sheet take-out port that can be opened and closed by providing discontinuous cutting lines for separation from the top to the front of a rectangular paper box containing roll sheets such as cooking paper and paper towels rolled up in roll form Storage boxes with improved ease of storage roll sheet removal (Patent Literature 1, Patent Literature 2), storage roll sheet cutting mechanism improved (Patent Literature 3), and opening / closing of a top-open type open / close paper box Many proposals have been made regarding improvement of the take-out opening / closing opening of the storage roll sheet, such as the one with improved recloseability (Patent Document 4).

直方体形状の紙箱の天面から正面にかけて切り離し用の不連続切断線を設けて開閉可能なシート取り出し口を形成するタイプのロールシート収納箱の場合、収納したシートの引き出し抵抗を少なくするためには、直方体形状の紙箱の正面の全幅にわたる大きな開口を形成することがよいとされている。
しかし、直方体形状の紙箱の正面の全幅にわたる大きな開口を形成した場合、引き出されるシートが上下、左右方向に自由に変形できる状態であるため、使用者によって個人差があるシートの引き出し方向のバラツキが引き出されるシートの捩れの原因となって引き出されたシートのカットが効率的に行われないことがある。 In the case of a roll sheet storage box of a type in which a discontinuous cutting line for separation is provided from the top surface to the front surface of a rectangular parallelepiped paper box to form an openable sheet outlet, in order to reduce the drag resistance of the stored sheet It is said that it is good to form a large opening over the entire width of the front of the rectangular parallelepiped paper box.
However, when a large opening over the entire width of the front of a rectangular parallelepiped paper box is formed, the drawn sheet is in a state that can be freely deformed in the vertical and horizontal directions. In some cases, the drawn sheet is not efficiently cut due to twisting of the drawn sheet.

本発明の直方体形状のロールシート収納紙箱１は、天面板３内から正面板２の下端縁Ｍに至る一対の切り離し用不連続切断線部Ｚ（Ｚ１−Ｚ２−Ｚ３−Ｚ４−Ｚ５）を全長にわたって切り離すことによって正面板２内に形成されるロールシート引き出し開口部Ａの部分の両側縁部に角部ａ部分が形成される。
そして、この角部ａが形成されている正面板２内の開口部Ａの最大幅部分となり、その幅は箱内から引き出されるロールシートの幅と略等しい幅となるので、引き出されるシートの両側縁部が略Ｖ字形状に括れている角部ａ内に誘導された状態で引き出される。その結果、引き出し方に個人差があっても常にシートの両側縁部が角部ａにより水平状態に保たれて引き出されることとなり、シート引き出し時におけるシートの捩れに起因する破れの発生を防止することができる。 The rectangular parallelepiped roll sheet storage paper box 1 of the present invention has a pair of discontinuous cutting line portions Z (Z1-Z2-Z3-Z4-Z5) for separation extending from the top plate 3 to the lower end edge M of the front plate 2. The corner | angular part a part is formed in the both-sides edge part of the part of the roll sheet drawer | drawing-out opening part A formed in the front plate 2 by cutting over.
And since it becomes the maximum width part of the opening part A in the front plate 2 in which this corner | angular part a is formed and the width | variety becomes a width | variety substantially equal to the width | variety of the roll sheet pulled out from the box, both sides of the sheet | seat pulled out It is pulled out in a state in which the edge portion is guided into a corner portion a that is bundled in a substantially V shape. As a result, even if there are individual differences in the pulling method, both side edges of the sheet are always pulled out while being held in a horizontal state by the corners a, thereby preventing the occurrence of tearing due to the twisting of the sheet when pulling out the sheet. be able to.

また、開口部Ａの角部ａは正面板２の両側縁部における折線Ｌ５上の前記直線状不連続切断線部Ｚ３によって形成される上下方向に短い直線部分を有していてロールシートの側縁部が上下方向に若干スライドできるので、ロールシートの側縁部の引き出し抵抗が大きくなるおそれもない。
また、引き出されるシートの両側縁は常に正面板２の両側縁部の角部ａ内に保持されるので、引き出したシートを上下の何れかの方向（ｂ、ｃ）にカットする場合でも波刃Ｅによる切断のみならず、角部ａのＶ字形状の開口縁による切断も円滑に行うことが可能である。 Moreover, the corner | angular part a of the opening part A has a short straight part in the up-down direction formed by the said linear discontinuous cutting line part Z3 on the broken line L5 in the both-sides edge part of the front board 2, and is the roll sheet side. Since the edge portion can be slightly slid in the vertical direction, there is no possibility that the pulling resistance of the side edge portion of the roll sheet is increased.
Further, since the both side edges of the drawn sheet are always held in the corners a of the both side edge parts of the front plate 2, even when the drawn sheet is cut in either the upper or lower direction (b, c) Not only the cutting by E but also the cutting by the V-shaped opening edge of the corner portion a can be performed smoothly.

さらに、正面板２の内側に波刃Ｅを上端縁に有する内側正面板６を接合した場合、前記Ｖ字形状の角部ａにおける波刃部分が引き出しシートのストッパーの役を果たすことができるので、引き出しシートを任意の長さに引き出した状態で確実に止めて切断できるし、シートカットも波刃部分を利用して綺麗に行うことが可能となる。 Further, when the inner front plate 6 having the wave edge E at the upper end edge is joined to the inner side of the front plate 2, the wave blade portion at the V-shaped corner portion a can serve as a stopper for the drawer sheet. In addition, the drawer sheet can be reliably stopped and cut in a state where the drawer sheet is pulled out to an arbitrary length, and the sheet cutting can be performed neatly by using the wave blade portion.

天面板３には、天面板３と背面板４の間の折線Ｌ２の部分における２点（ｘ１、ｘ２）を基点として、天面板３と正面板２との間の折線Ｌ１上の２点（ｙ１、ｙ２）まで天面板３内を左右対称形に一対の天面板内不連続切断線部（Ｚ１）が形成され、さらに、正面板２内には、上記正面板２と天面板３の間の折線Ｌ１上の２点（ｙ１、ｙ２）から正面板２とその両側面閉鎖板２ａ，２ｂの間の折線Ｌ５上の天面側の１点（ｗ１、ｗ１）にかけて一対の天面板側の傾斜不連続切断線部（Ｚ２、Ｚ２）が形成されており、該天面側の点（ｗ１）から下端縁Ｍ側の１点（ｗ２，ｗ２）までの折線Ｌ５部分に直線状不連続切断線部（Ｚ３、Ｚ３）が形成され、該下端縁Ｍ側の１点（ｗ２，ｗ２）から正面板２の下端縁Ｍの２点（ｍ１，ｍ２）まで一対の正面板下端縁側の傾斜不連続切断線部（Ｚ４、Ｚ４）が形成されている。 The top plate 3 has two points on the fold line L1 between the top plate 3 and the front plate 2 (x1 and x2) at the fold line L2 portion between the top plate 3 and the back plate 4 as base points ( A pair of discontinuous cutting lines (Z1) in the top panel are formed symmetrically in the top panel 3 up to y1, y2), and further, in the front panel 2, between the front panel 2 and the top panel 3 A pair of top plate from the two points (y1, y2) on the fold line L1 to one point (w1, w1) on the top surface side on the fold line L5 between the front plate 2 and both side surface closing plates 2a, 2b. An inclined discontinuous cutting line portion (Z2, Z2) is formed, and a linear discontinuous cutting is performed at a fold line L5 portion from a point (w1) on the top surface side to one point (w2, w2) on the lower edge M side. A line portion (Z3, Z3) is formed, and a pair is formed from one point (w2, w2) on the lower edge M side to two points (m1, m2) on the lower edge M of the front plate 2. Slope discontinuity cut line portion of the front plate lower edge (Z4, Z4) are formed.

天面板３内の切り離し可能な一対の天面板内不連続切断線部（Ｚ１，Ｚ１）の基点（ｘ１、ｘ２）の位置として、図１には、天面板３と背面板４の間の折線Ｌ２上の位置が示されているが、この基点（ｘ１、ｘ２）の位置は、天面板３内であれば特に制限はない。全長にわたる一対の不連続切断線部（Ｚ，Ｚ）を全長にわたって切り離してロールシート引き出し開口部Ａを形成した際に、同時に形成される蓋部Ｂによるロールシート引き出し開口部Ａの開閉操作がし易いことや、天面板３における天面板内の不連続切断線部（Ｚ１，Ｚ１）の基点（ｘ１とｘ２）の間の距離を、折線Ｌ１上の２点ｙ１とｙ２の間の距離よりも短くすると意匠的な効果において優れていること等から、基点（ｘ１、ｘ２）の位置は図示されている位置であることが好ましい。 As the position of the base point (x1, x2) of a pair of discontinuous cutting line portions (Z1, Z1) in the top plate 3 that can be separated in the top plate 3, FIG. 1 shows a fold line between the top plate 3 and the back plate 4. Although the position on L2 is shown, the position of the base point (x1, x2) is not particularly limited as long as it is within the top panel 3. When the roll sheet drawer opening A is formed by cutting the pair of discontinuous cutting line sections (Z, Z) over the entire length to form the roll sheet drawer opening A, the roll sheet drawer opening A is opened and closed by the lid B formed at the same time. The distance between the base points (x1 and x2) of the discontinuous cutting line portions (Z1, Z1) in the top plate in the top plate 3 is greater than the distance between the two points y1 and y2 on the broken line L1. Since the shortening is excellent in the design effect, the position of the base point (x1, x2) is preferably the position shown in the figure.

また、天面板内の不連続切断線部（Ｚ１，Ｚ１）の天面板３と正面板２の間の折線Ｌ１上の２点（ｙ１、ｙ２）の位置は、正面板２内において、正面板２とその両側縁閉鎖板（２ａ，２ｂ）との間の両折線Ｌ５上の天面板側の１点（ｗ１，ｗ１）とを結ぶ天面板側の傾斜不連続切断線部（Ｚ２，Ｚ２）と、同折線Ｌ５上の前記天面側の１点（ｗ１、ｗ１）より下方の両折線Ｌ５上の点（ｗ２、ｗ２）と正面板２の下端縁Ｍの２点（ｍ１、ｍ２）とを結ぶ正面板下端縁側の傾斜不連続切断線部（Ｚ４，Ｚ４）とによって、正面板２の両側縁に形成される横向きＶ字状の角部ａの角度ｆ２を８０°〜９０°とすることが必要であることから、折線Ｌ１の左右両端部に近い図１に示される位置である。 Further, the positions of two points (y1, y2) on the fold line L1 between the top plate 3 and the front plate 2 of the discontinuous cutting line portions (Z1, Z1) in the top plate are as follows.
