Description

  The present invention relates to a laminate of sheet-like materials, and more particularly to a laminate of sheet-like materials laminated so that the wet tissue can be continuously taken out in a folded state of the wet wet tissue.

  Conventionally, wet tissues obtained by impregnating a fiber material such as paper, woven fabric, or nonwoven fabric with a chemical solution containing alcohol, a humectant, a surfactant, and the like are accommodated in a package having airtightness or liquidtightness. The wet tissue is used for various purposes such as wiping off dirt on the skin, removing makeup, wiping the bottom of an infant, and cleaning a toilet. In this type of package, an outlet having an open / close lid is provided at one place of the package, and the wet tissue accommodated therein can be taken out from the outlet. In addition, this wet tissue is folded in various shapes, a plurality of layers are stacked, and when one wet tissue is lifted, the wet tissue stacked under it is also lifted and stacked so that it can be removed continuously. A laminate of the formula is formed.

  As shown in FIG. 4A, a conventional wet tissue laminate 100 is obtained by folding and laminating a plurality of wet tissues 101. More specifically, the wet tissue 101 is formed by folding the folded line 102 with the upper folded piece 103 and the lower folded piece 104, and the direction opposite to the direction in which the free end side of the lower folded piece 104 is folded at the folded line 102. The overlapping end 105 having a short width is formed. Further, the wet tissue 101 folded as described above is divided into a right-sided waist folded wet tissue 101R and a left-sided waist folded wet tissue 101L depending on the direction of folding along the fold line 102. The wet tissue laminate 100 is formed by assembling the short overlapped end 105 of each right-facing waist folded wet tissue 101R in the hands of the free end of the upper folded piece 103 of each left-facing waist folded wet tissue 101L and each left-facing waist folded wet. It is formed by assembling the short overlapped end 105 of the tissue 101L on the free end side of the upper folded piece 103 of each right-facing waist folded wet tissue 101R and the hand of the phase. Moreover, the laminated body 100 of the wet tissue has a configuration in which the short width overlapping end 105 of the wet tissue 101 is divided into the left half side and the right half side (see Patent Document 1).

  By the way, the wet tissue used for many purposes is desired to have a large size of one wet tissue.

  However, when a laminate having a conventional folding structure is manufactured using a wet tissue having a size larger than the conventional size, the width of the resulting laminate is inevitably larger than the conventional size, and the size of the package is reduced. In addition to changing the design of the wet tissue laminate manufacturing apparatus, the packaging manufacturing apparatus must also be changed. In addition, if the size of the package is changed, the size of the cardboard used at the time of product shipment must be changed, resulting in a change in inventory space, and changing the size of one wet tissue to change the standard. There are many points that must be made.

  Moreover, in the taking-out structure shown in Patent Document 1, the finished laminate has a substantially rectangular cross section as shown in FIG. 4B. However, the stacked display used when displaying the package containing the laminate as a product has a substantially rectangular cross section, so it seems to be stable at first glance. In some cases, the stability could be affected.

Japanese Patent No. 2951187

  Therefore, in view of the above-described problems, the present invention provides a structure in which a larger-sized sheet-like material can be stacked while the size of the package is the same as the conventional size, It aims at providing the laminated body of the sheet-like material with the sense of stability at the time of stacking.

The laminate of sheet-like materials according to the present invention is a laminate of sheet-like materials laminated so that a plurality of folded sheet-like materials can be continuously taken out. A first intermediate piece formed to have a length substantially the same as the width dimension of the laminated body, and a fold line parallel to one side of the sheet-like material is folded downward in the stacking direction. The second intermediate piece formed adjacent to the first intermediate piece and having a width of 2 is folded back from the second intermediate piece in the stacking direction so as to have substantially the same width as the second intermediate piece. The first folded piece formed and the first intermediate piece are folded back to the upper side in the stacking direction so that the width of the first intermediate piece is adjusted to the desired width of the laminate, and the first The first folded piece is folded so as to have a second folded piece that is ½ or less of the width of the intermediate piece . And the even-numbered sheet-like material and the odd-numbered sheet-like material of the laminated sheet-like material are laminated in a folded state so as to be symmetrical, and each even-numbered (odd-numbered) material is laminated. The first of the odd-numbered (even-numbered) sheet-like materials stacked next to the sheet-like material in a valley formed by the first intermediate piece and the second intermediate piece of the sheet-like material. And a peak portion formed by the intermediate piece and the second folded piece.

  In the present invention, since the second folded piece that is not in the conventional laminated structure is provided, even if it is a sheet-like material having a size larger than the conventional one by the area of the second folded piece, It is possible to form a laminate having the same size as the above. For this reason, it is not necessary to change the design of the manufacturing apparatus for the packaging body for packaging the finished laminated body, and further, it is not necessary to change the size of the corrugated cardboard or the like used at the time of product shipment.

  Further, the present invention provides each odd-numbered sheet-like material stacked next to the above-mentioned sheet-like material in a trough formed by the first intermediate piece and the second intermediate piece of each even-numbered sheet-like material. The first intermediate piece and the second intermediate piece of the odd-numbered sheet-like material are similarly overlapped by overlapping the mountain portions formed by the first intermediate piece and the second folded piece. In the valley portion formed by the above, the peak portions formed by the first intermediate piece and the second folded piece of each even-numbered sheet-like material stacked next to the sheet-like material are overlapped and crossed. Therefore, the formed sheet-like laminate itself has a thick portion in the vicinity of the first fold line and the third fold line of each sheet-like material, as long as the second fold is provided. It is formed and the stability at the time of stacking the laminated bodies can be improved.

  Hereinafter, the best mode of a sheet-like product laminate according to the present invention will be described in detail with reference to the drawings.

The portion corresponding to the length of the second intermediate piece 12 of the long sides 10a and 10b of the sheet-like object 10, that is, the distance B between the first fold line 15 and the second fold line is the length 11a of the first intermediate piece 11. Is approximately half the length.

  The first folded piece 13 is adjacent to the second intermediate piece 12, and is surrounded by the long sides 10a and 10b parallel to the length direction of the sheet-like object 10, the second broken line 16, and the short side 10d. Part. The portion corresponding to the length of the first folded piece 13 of the long sides 10a and 10b of the sheet-like object 10, that is, the distance C between the second broken line 16 and the short side 10d is substantially the same as the distance B.

  The second folded piece 14 is adjacent to the first intermediate piece 11 and is surrounded by the long sides 10a and 10b parallel to the length direction of the sheet-like object 10, the third broken line 17 and the short side 10c. It is. The distance D between the portion corresponding to the length of the second folded piece 14 of the long sides 10a and 10b of the sheet-like object 10, that is, the third broken line 17 and the short side 10c has a relationship of D <C. That is, the distance D is a value smaller than half of the distance A.

  As shown in FIGS. 2 and 3A, the sheet-like object 10 composed of the above-described parts is folded back at the respective polygonal lines 15, 16, and 17. That is, the sheet-like object 10 is folded back in the first folding line 15 in the direction opposite to the stacking direction (−z direction) to form the first intermediate piece 11 and the second intermediate piece 12, and the second folding line 16 A first folded piece 13 is formed in a direction opposite to the stacking direction (−z direction), and a second folded piece 14 is formed in the third folding line 17 in the stacking direction (z direction).

  Next, the laminated structure of the sheet-like laminate 1 will be described with reference to FIGS. 2, 3A, and 3B.

  In the sheet-like material laminate 1, the sheet-like material 10 is crossed at a predetermined position. That is, in the sheet-like material stack 1, the even-numbered sheet-like material 10R and the odd-numbered sheet-like material 10L are crossed with each other.

  For convenience, the sheet-like object 10R is a sheet-like object in which the second intermediate piece 12 and the first folded piece 13 are provided on the right side in FIG. A sheet-like material in which the second intermediate piece 12 and the first folded piece 13 are provided on the left side in FIG. 2 with respect to the first intermediate piece 11 of the sheet-like material 10 is referred to as a sheet-like material 10L. Further, the sheet-like material 10R and the sheet-like material 10L in the present description are folded back so that the sheet-like material 10 is symmetric with respect to the short side 10c (direction parallel to the y-axis). It has the same configuration as the sheet-like material 10. Further, the sheet-like material 10R is an even-numbered sheet-like material shown in FIGS. 2 and 3 (A), and the sheet-like material 10L is an odd-numbered material shown in FIGS. 2 and 3 (A). Sheet-like material.

  Specifically, the sheet-like material laminate 1 is a sheet that is laminated next to each sheet-like material 10R in a trough formed by the first intermediate piece 11 and the second intermediate piece 12 of each sheet-like material 10R. The peaks formed by the first intermediate piece 11 and the second folded piece 14 of the sheet-like object 10L are overlapped and crossed, and can be formed by the first intermediate piece 11 and the second intermediate piece 12 of each sheet-like object 10L. In the valley portion, a pile formed by the first intermediate piece 11 and the second folded piece 14 of the sheet-like material 10R laminated next to each sheet-like material 10L is overlapped to form a laminated body as an intersection.

  The sheet-like product laminate 1 configured as described above has the second folded piece 14 that is not in the conventional laminated structure, so that the second folded piece 14 has the same width as the conventional laminated product. The sheet-like material 10 having a size larger than that of the conventional sheet can be stacked by the area of. Specifically, the sheet-like material 10 has a size within the range of the area of the second folded piece 14, that is, the above-described relationship of D <C, as compared with the size of a conventionally used sheet-like material. Can be used, and sheets up to about 25% in size can be used. Therefore, even if the size of the sheet-like material to be laminated is changed, only the design change of the production device for the sheet-like material laminate, and the design change of the production device for the packaging body for packaging the finished laminate is not required, Furthermore, it is not necessary to change the size of cardboard or the like used at the time of product shipment, and it is not necessary to change the inventory space.

  Moreover, the sheet-like laminated body 1 is a sheet-like thing 10L laminated | stacked next to each sheet-like thing 10R in the trough formed by the 1st intermediate piece 11 and the 2nd intermediate piece 12 of each sheet-like thing 10R. In the valley portion formed by the first intermediate piece 11 and the second intermediate piece 12 of each sheet-like material 10L, the peak portions formed by the first intermediate piece 11 and the second folded piece 14 are overlapped and crossed. The crests formed by the first intermediate piece 11 and the second folded piece 14 of the sheet-like material 10R laminated next to each sheet-like material 10L are overlapped to be crossed. Therefore, as shown in FIG. 3B, the formed sheet-like laminate 1 itself has a bulky state in the vicinity of the first broken line 15 and the third bent line 17, that is, the end of the sheet-like laminated body 1. In the vicinity, the bulk of the laminate is increased by the size of the second folded piece 14. That is, in the sheet-like product laminate 1, a thick portion is formed in the vicinity of the first fold line 15 and the third fold line 17 of each sheet-like material 10 by the size of the second fold piece 14. Then, the casing portion of the laminated body is reinforced, and the sense of stability when the laminated bodies are overlaid can be improved.

  The second folded piece 14 is provided for the purpose of enlarging the size of the sheet-like object 10 and reinforcing the casing portion of the sheet-like article laminate 1. When the distance D between the broken line 17 and the short side 10c is larger than the distance C, the second folded piece 14 of each sheet-like material 10R (or the sheet-like material 10L) and each sheet-like shape are obtained in the finished sheet-like laminate 1. The first folded piece 13 of the object 10L (or the sheet-like object 10R) overlaps, and the overall bulky state becomes unstable due to the central portion swelling. Therefore, in the present invention, the distance D between the third broken line 17 of the second folded piece 14 and the short side 10c is set to D <C.
