Description

衛生薄頁紙  Hygienic tissue paper  

本發明涉及衛生薄頁紙。 The present invention relates to sanitary tissue paper.

廚房紙等衛生薄頁紙具備層疊有實施了壓花加工的皺紋紙等片材的層疊結構。對於以往的衛生薄頁紙，為了賦予油分、水分的吸收性能，對各片材實施壓花加工，在一個面上形成凸部(以下，稱為壓花凸部)，在另一個面上形成與該凸部對應的凹部(以下，稱為壓花凹部)，將這些片材層疊，從而在層疊的片材間形成空間(壓花空間)，在該壓花空間保持有吸收的油分等。 The sanitary tissue paper such as kitchen paper has a laminated structure in which sheets such as crepe paper subjected to embossing are laminated. In the conventional sanitary tissue, in order to impart oil and moisture absorption properties, each sheet is subjected to embossing, and a convex portion (hereinafter referred to as an embossed convex portion) is formed on one surface and formed on the other surface. A concave portion (hereinafter referred to as an embossed concave portion) corresponding to the convex portion is formed by laminating the sheets to form a space (embossing space) between the laminated sheets, and an absorbed oil or the like is held in the embossed space.

此外，在這種衛生薄頁紙中，為了提高設計性、吸收性能(水分、油分的吸收量．保持量等)，在各片材上形成藉由壓花加工而形成的壓花凸部和與該凸部對應的壓花凹部以及被多個壓花凸部包圍的不存在壓花凸部的部分(以下，稱為非壓花凸部)，進而，形成未形成這些壓花凸部和非壓花凸部的部分(以下，稱為非壓花部)彼此對置的非壓花空間，藉由使油分等通過該非壓花空間，從而油分等的吸收性能變高。 Further, in such sanitary tissue paper, in order to improve designability and absorption performance (water absorption, oil absorption amount, holding amount, etc.), embossing convex portions formed by embossing are formed on each sheet and An embossed concave portion corresponding to the convex portion and a portion (hereinafter referred to as a non-embossed convex portion) surrounded by the plurality of embossed convex portions without embossing convex portions, and further, the embossing convex portions are not formed and The non-embossed space in which the portions of the non-embossed convex portions (hereinafter referred to as non-embossed portions) face each other, and the oil component or the like passes through the non-embossed space, whereby the absorption performance of the oil component or the like is increased.

例如，在日本特公平6-28951號公報(專利文獻1)的圖2中公開了具備使經壓花加工的2片皺紋紙的凸部的頂部彼此相對而黏接的頂對頂(Tip To Tip)形式的層疊結構的廚房紙巾等衛生紙。另外，在美國專利第8409404號說明書(專利文獻2)中公開了具備以一個皺紋紙的凸部的頂部位於另一個皺紋紙的不是凸部的部分(從相對的一個皺紋紙來看被多個壓花凸部包圍的未形成凸部的部分)的方式相互不同地佈置凸部而黏接的嵌套(Nested)形式的層疊結構的廚房紙。進而，在日本特開2008-208501號公報(專利文獻3)中公開了在內部具備交叉的線狀的非壓花空間的廚房紙。 In Fig. 2 of Japanese Patent Publication No. 6-28951 (Patent Document 1), a top-to-top (Tip To) is provided which has a top portion of a convex portion of two crepe papers which are embossed and adhered to each other. Tip) A toilet paper such as a kitchen towel in the form of a laminated structure. In addition, in the specification of U.S. Patent No. 8,490,404 (Patent Document 2), a portion having a convex portion having one crepe paper is located at a portion of another crepe paper which is not a convex portion (a plurality of crepe papers are viewed from the opposite one) A kitchen paper of a nested structure of a Nested form in which the convex portions are disposed differently from each other in such a manner that the convex portion is not formed by the embossing convex portions. Further, Japanese Laid-Open Patent Publication No. 2008-208501 (Patent Document 3) discloses a kitchen paper having a line-shaped non-embossed space that intersects inside.

專利文獻3：日本特開2008-208501號公報 Patent Document 3: Japanese Laid-Open Patent Publication No. 2008-208501

然而，對於專利文獻1的結構(頂對頂形式的層疊結構)，存在如下問題：對層疊方向(厚度方向)的強度較弱，在使用衛生薄頁紙時(例如，在鋪在盤子上的廚房紙上放置油炸食品的情況等)，由於負荷而吸收的油分等滲出(透印)到衛生薄頁紙的背面側(例如，載置廚房紙的盤子)。 However, with the structure of the patent document 1 (the top-to-top type laminated structure), there is a problem that the strength in the lamination direction (thickness direction) is weak, when using a sanitary tissue paper (for example, on a plate) When the fried food is placed on the kitchen paper, etc., the oil absorbed by the load is oozing out (printed) to the back side of the sanitary tissue (for example, a dish on which the kitchen paper is placed).

另外，對於專利文獻2的結構(嵌套形式的層疊結構)，雖然與頂對頂形式的層疊結構相比能夠減小與使用物件的接觸面積，但由於壓花空間小，因此即使在使用時受到負荷時產生的微小的壓花空間的壓扁，也使油分等變得難以吸收，另外，存在吸收的油分滲出的問題。 Further, with the structure of the patent document 2 (the laminated structure of the nested form), although the contact area with the article to be used can be reduced as compared with the laminated structure of the top-to-top type, since the embossed space is small, even when it is used The crushing of the minute embossed space generated by the load also makes it difficult to absorb oil and the like, and there is a problem that the absorbed oil is oozing out.

進而，對於專利文獻3所公開的具有非壓花空間的衛生薄頁紙，由於在非壓花空間不存在由壓花凸部形成的柱，因此，對厚度方向的負荷的強度降低。因此，對於存在這樣的非壓花空間的以往的衛生薄頁紙，不論頂對頂形式、嵌套形成的層疊結構，均存在如果對厚度方向施加負荷，則非壓花空間壓扁，吸油性能降低的問題。 Further, in the sanitary tissue having the non-embossed space disclosed in Patent Document 3, since the column formed by the embossed convex portion does not exist in the non-embossed space, the strength against the load in the thickness direction is lowered. Therefore, in the conventional sanitary tissue paper having such a non-embossed space, regardless of the top-to-top form or the nested laminated structure, if the load is applied in the thickness direction, the non-embossed space is flattened and the oil absorbing performance is obtained. Reduced problems.

另外，藉由減小這樣的非壓花空間，能夠提高厚度方向的強度，但由於非壓花空間的空間體積的減少而油分等的擴散性降低，另外，由於各片材中的非壓花部的面積減小，因此，設計性降低。另外，在各片材所夾住的空間存在非壓花空間交叉的交叉部時，油分等在該交叉部滯留，阻礙油分等的擴散，因此，吸收性能進一步降低。 Further, by reducing such a non-embossed space, the strength in the thickness direction can be increased, but the diffusibility of the oil component or the like is lowered due to the decrease in the spatial volume of the non-embossed space, and the non-embossing in each sheet is also caused. The area of the portion is reduced, and thus the design is lowered. In addition, when there is an intersection where the non-embossed space intersects in the space sandwiched by each sheet, oil or the like is retained at the intersection, and the diffusion of oil or the like is inhibited, so that the absorption performance is further lowered.

本發明的目的在於提供一種維持吸收性、設計性並且負荷時的吸收性能優異的衛生薄頁紙。 An object of the present invention is to provide a sanitary tissue which is excellent in absorbability and durability while maintaining absorbability and design properties.

為了解決上述課題，本發明的第1方式是一種衛生薄頁紙，是將2片以上的片材重疊而一體化的衛生薄頁紙，具有由上述2片以上的片材中在重疊方向鄰接的至少2片片材構成，且該2片片材各自在正面和背面形成有多個壓花 凸部和與該壓花凸部對應的壓花凹部的一對片材，上述一對片材具有壓花凸部的形成面以嵌套形式相對的第1片材和第2片材，上述第1片材具有形成有多個壓花凸部和多個非壓花凸部的壓花部以及未形成多個壓花凸部和多個非壓花凸部的非壓花部，上述第2片材具有形成有多個壓花凸部和多個非壓花凸部的壓花部，不具有未形成多個壓花凸部和多個非壓花凸部的非壓花部。 In order to solve the problem, the first aspect of the present invention is a sanitary tissue paper which is a sanitary tissue sheet in which two or more sheets are superposed and integrated, and has two or more sheets adjacent to each other in the overlapping direction. And a pair of sheets each having a plurality of embossing convex portions and embossing concave portions corresponding to the embossing convex portions, the pair of sheets are formed on at least two sheets, and the two sheets are respectively formed on the front surface and the back surface The first sheet and the second sheet having the embossed convex portion forming surface in a nested form, the first sheet having an embossed portion in which a plurality of embossed convex portions and a plurality of non-embossed convex portions are formed And a non-embossed portion in which a plurality of embossed convex portions and a plurality of non-embossed convex portions are not formed, and the second sheet has an embossed portion in which a plurality of embossed convex portions and a plurality of non-embossed convex portions are formed, There is no non-embossed portion in which a plurality of embossed convex portions and a plurality of non-embossed convex portions are not formed.

衛生薄頁紙將2片以上的片材重疊而一體化。衛生薄頁紙沒有特別限定，也包含廚房紙、棉紙、幹式或含浸了水、藥液的濕式的衛生薄頁紙。關於衛生薄頁紙的用途，家庭用、業務用的衛生薄頁紙都可以成為對象。此外，2片以上的片材可以使用用於衛生薄頁紙的習知的皺紋紙。各片材可以使用相同的材質，也可以使用不同的材質。此外，將2片以上的片材重疊而一體化是指多片片材在上下方向疊加而構成1片衛生薄頁紙。 The sanitary tissue is formed by overlapping two or more sheets. The sanitary tissue paper is not particularly limited, and includes kitchen paper, cotton paper, dry or wet sanitary tissue impregnated with water or liquid medicine. Regarding the use of sanitary tissue paper, sanitary tissue paper for household use and business can be targeted. Further, as the conventional crepe paper for sanitary tissue, two or more sheets can be used. Each sheet can be made of the same material or a different material. Further, the fact that two or more sheets are superposed and integrated means that a plurality of sheets are stacked in the vertical direction to form one sheet of sanitary tissue.

一對片材由2片以上的片材中在重疊方向鄰接的至少2片片材構成。重疊方向是指2片以上的片材所疊加的方向(衛生薄頁紙的厚度方向)。此外，在重疊方向鄰接的至少2片片材是指在疊加的2片以上的片材中，上下鄰接而被疊加的2片片材。進而，構成一對片材的2片片材在各個片材上在正面和背面形成有多個壓花凸部和與該壓花凸部對應的壓花凹部。 The pair of sheets is composed of at least two sheets adjacent to each other in the overlapping direction of the two or more sheets. The overlapping direction refers to a direction in which two or more sheets are superimposed (thickness direction of the sanitary tissue). Further, at least two sheets adjacent to each other in the overlapping direction are two sheets which are superposed adjacent to each other in two or more sheets which are superimposed. Further, on each of the two sheets constituting the pair of sheets, a plurality of embossed convex portions and embossed concave portions corresponding to the embossed convex portions are formed on the front and back surfaces of the respective sheets.

壓花凸部為藉由壓花加工而形成在該片材的凸部。壓花凹部為在該片材上與壓花凸部正面和背面一體地形成的凹部。非壓花凸部表示被多個壓花凸部包圍的未形成凸部的部分。 The embossing convex portion is formed in a convex portion of the sheet by embossing. The embossed recess is a recess formed integrally with the front and back surfaces of the embossing projection on the sheet. The non-embossed convex portion indicates a portion where the convex portion is not surrounded by the plurality of embossed convex portions.

一對片材具有壓花凸部的形成面以嵌套形式相對的第1片材和第2片材。使壓花凸部的形成面以嵌套形式相對是指使一對片材中第1片材的壓花凸部的頂部與第2片材的不是壓花凸部的部分(從第1片材來看被壓花凸部包圍的未成為凸的部分，以下，稱為非壓花凸部)相對，且使第2片材的壓花凸部的頂部與第1片材的不是壓花凸部的部分(從第2片材來看被壓花凸部包圍而未成為凸的部分，以下，稱為非壓花凸部)相對。壓花凸部的頂部可以與相對的非壓花凸部接觸。此外，壓花凸部的頂部可以與相對的非壓花凸部黏接。 The pair of sheets have a first sheet and a second sheet in which the forming faces of the embossing projections face each other in a nested form. The formation of the embossed convex portion in a nested manner refers to the top of the embossed convex portion of the first sheet of the pair of sheets and the portion of the second sheet that is not the embossed convex portion (from the first sheet) The non-embossed portion surrounded by the embossed convex portion, hereinafter referred to as a non-embossed convex portion, is opposed to each other, and the top portion of the embossed convex portion of the second sheet and the first sheet are not embossed convex portions. The portion of the portion (the portion that is surrounded by the embossed convex portion and is not convex as viewed from the second sheet, hereinafter referred to as a non-embossed convex portion) faces each other. The top of the embossing protrusion can be in contact with the opposing non-embossed protrusions. Additionally, the top of the embossing projections can be bonded to the opposing non-embossed projections.

一對片材中第1片材具有壓花部和非壓花部。壓花部形成有多個壓花凸部和多個非壓花凸部。非壓花部沒有形成多個壓花凸部和多個非壓花凸部中的任一者。此外，一對片材中第2片材具有壓花部，不具有非壓花部。即，第2 片材僅形成有多個壓花凸部和多個非壓花凸部。 The first sheet of the pair of sheets has an embossed portion and a non-embossed portion. The embossed portion is formed with a plurality of embossed convex portions and a plurality of non-embossed convex portions. The non-embossed portion does not form any of a plurality of embossed convex portions and a plurality of non-embossed convex portions. Further, the second sheet of the pair of sheets has an embossed portion and does not have a non-embossed portion. That is, the second sheet is formed only with a plurality of embossed convex portions and a plurality of non-embossed convex portions.

在第1方式中，以具有壓花部和非壓花部的第1片材與具有壓花部且不具有非壓花部的第2片材相對的方式構成一對片材。在這種構成中，在一對片材間非壓花部彼此不會相對，因此在第1片材與第2片材之間不會形成非壓花空間(藉由非壓花部彼此相對而形成且容易相對於厚度方向的負荷而壓扁的空間)。因此，可以提高衛生薄頁紙的對負荷的厚度方向的強度，能夠提高負荷時的吸收性能(例如，減少油分等的透印)。 In the first aspect, the first sheet having the embossed portion and the non-embossed portion is formed to face the second sheet having the embossed portion and having no non-embossed portion. In such a configuration, since the non-embossed portions do not face each other between the pair of sheets, a non-embossed space is not formed between the first sheet and the second sheet (with respect to each other by the non-embossed portions) And a space which is formed and which is easily crushed with respect to the load in the thickness direction). Therefore, it is possible to increase the strength of the sanitary tissue in the thickness direction of the load, and it is possible to improve the absorption performance at the time of load (for example, to reduce the offset of oil or the like).

此外，即使是在這樣的一對片材間非壓花部彼此不相對的結構，由於在衛生薄頁紙內配置有非壓花部，因此也可以在衛生薄頁紙內介由該非壓花部擴散油分等。因此，根據第1方式，即使不存在非壓花空間，也能夠維持吸收的油分等的擴散性。 Further, even in a configuration in which the non-embossed portions are not opposed to each other between the pair of sheets, since the non-embossed portion is disposed in the sanitary tissue, the non-embossing can be imparted in the sanitary tissue. Diffusion of oil and so on. Therefore, according to the first aspect, even if there is no non-embossed space, the diffusibility of the absorbed oil or the like can be maintained.

此外，在這樣的一對片材間不存在非壓花空間的結構中，當然也不存在非壓花空間交叉的交叉部(容易滯留油分等的部分)，因此能夠提高油分等的擴散性、減少油分等的透印。 Further, in the configuration in which there is no non-embossed space between the pair of sheets, of course, there is no intersection portion (a portion where oil or the like is easily retained) where the non-embossed spaces intersect, so that the diffusibility of oil or the like can be improved, Reduce the penetration of oil and the like.

此外，在衛生薄頁紙中，由於非壓花空間成為發揮設計性的部分，因此若不存在非壓花空間則設計性降低，但在第1方式中，由於僅形成在第1片材上的非壓花部被配置于衛生薄頁紙內，因此即使不存在非壓花空間，也能夠維持設計性。 Further, in the sanitary tissue, since the non-embossed space is a part that exhibits designability, the design property is lowered if there is no non-embossed space, but in the first aspect, it is formed only on the first sheet. Since the non-embossed portion is disposed in the sanitary tissue, the design can be maintained even if there is no non-embossed space.

此外，在第1方式中，一對片材採用嵌套形式的層疊結構，一對片材中第2片材具有僅由壓花部形成的片材，因此能夠減少衛生薄頁紙的與使用物件的接觸面積，即使在使用時施加負荷，衛生薄頁紙內的空間也不容易壓扁。而且，即使在一對片材間不設置非壓花空間，也可以維持吸收速度，此外，提高負荷時的吸收性能的同時減小每平方米的重量、紙厚，可以減薄衛生薄頁紙的厚度。 Further, in the first aspect, the pair of sheets have a laminated structure in a nested form, and the second sheet of the pair of sheets has a sheet formed only of the embossed portion, so that the use and use of the sanitary tissue can be reduced. The contact area of the article, even if a load is applied during use, the space inside the sanitary tissue is not easily crushed. Further, even if a non-embossed space is not provided between the pair of sheets, the absorption speed can be maintained, and the weight and paper thickness per square meter can be reduced while improving the absorption performance at the time of load, and the sanitary tissue can be thinned. thickness of.

在第2方式中，具有上述2片以上的片材中位於上述重疊方向的兩端部中的至少一端的端部片材，上述端部片材具有形成有多個壓花凸部和多個非壓花凸部的壓花部以及未形成多個壓花凸部和多個非壓花凸部的非壓花部。重疊方向的兩端部中的至少一端是指將重疊方向放置成上下方向的情況下的最上端 或最下端，構成衛生薄頁紙的正面或背面。此外，端部片材為位於該最上端或最下端的片材，即，構成衛生薄頁紙的正面或背面的片材。 In the second aspect, the end sheet having at least one of the end portions of the two or more sheets in the overlapping direction, wherein the end sheet has a plurality of embossing projections and a plurality of An embossed portion of the non-embossed convex portion and a non-embossed portion in which a plurality of embossed convex portions and a plurality of non-embossed convex portions are not formed. At least one of the both end portions in the overlapping direction means the uppermost end or the lowermost end when the overlapping direction is placed in the vertical direction, and constitutes the front or back surface of the sanitary tissue. Further, the end sheet is a sheet located at the uppermost or lowermost end, that is, a sheet constituting the front or back of the sanitary tissue.

在第2方式中，藉由以此方式具有非壓花部的端部片材位於重疊方向的兩端部的一端，從而具有可發揮設計性的非壓花部的片材被配置于衛生薄頁紙的正面或背面。因此，可以提供從外部來看的辨識性良好的衛生薄頁紙。 In the second aspect, the end sheet having the non-embossed portion in this manner is located at one end of both end portions in the overlapping direction, and the sheet having the non-embossed portion capable of exhibiting design is disposed on the sanitary sheet. The front or back of the sheet of paper. Therefore, it is possible to provide a hygienic tissue paper which is well-recognized from the outside.

在第3方式中，上述端部片材由具有上述非壓花部的上述第1片材構成。第1片材構成以嵌套形式形成的一對片材的一部分，此外，以嵌套形式形成的一對片材的對厚度方向的負荷的強度較高。即，在第3方式中，在直接受到向厚度方向的負荷的衛生薄頁紙的正面或背面，以嵌套形式形成的一對片材中配置有第1片材(具有非壓花部的片材)。因此，即使在衛生薄頁紙的內部不存在非壓花空間的情況下，也能夠提高衛生薄頁紙的對負荷的厚度方向的強度，並且維持設計性。 In the third aspect, the end sheet is composed of the first sheet having the non-embossed portion. The first sheet constitutes a part of a pair of sheets formed in a nested form, and the pair of sheets formed in a nested form has a high strength against a load in the thickness direction. In other words, in the third aspect, the first sheet (the non-embossed portion) is disposed in a pair of sheets formed in a nested form on the front surface or the back surface of the sanitary tissue directly subjected to the load in the thickness direction. Sheet). Therefore, even in the case where there is no non-embossed space inside the sanitary tissue, the strength of the sanitary tissue in the thickness direction of the load can be improved, and the design can be maintained.

在第4方式中，具有上述2片以上的片材中位於上述重疊方向的兩端部中的至少一端的端部片材，上述端部片材具有形成有多個壓花凸部和多個非壓花凸部的壓花部，且不具有未形成多個壓花凸部和多個非壓花凸部的非壓花部。即，端部片材僅具有形成有多個壓花凸部和多個非壓花凸部的壓花部。 In the fourth aspect, the end sheet having at least one of the end portions of the two or more sheets in the overlapping direction, wherein the end sheet has a plurality of embossing projections and a plurality of The embossed portion of the non-embossed convex portion does not have a non-embossed portion in which a plurality of embossed convex portions and a plurality of non-embossed convex portions are not formed. That is, the end sheet has only the embossed portion in which the plurality of embossed convex portions and the plurality of non-embossed convex portions are formed.

在第4方式中，藉由以這種方式使僅具有壓花部的端部片材位於重疊方向的兩端部的一端，從而與具有非壓花部的片材相比不具有對負荷的厚度方向的強度高的非壓花部的片材被配置于衛生薄頁紙的正面或背面。即，由於可以在直接受到向厚度方向的負荷的衛生薄頁紙的正面或背面配置相對於厚度方向的負荷的強度高的片材，因此可以提高衛生薄頁紙整體的厚度方向的強度。 In the fourth aspect, by providing the end sheets having only the embossed portions at one end of both end portions in the overlapping direction in this manner, there is no load on the sheet having the non-embossed portion. The sheet of the non-embossed portion having a high strength in the thickness direction is disposed on the front surface or the back surface of the sanitary tissue. In other words, since the sheet having a high strength against the load in the thickness direction can be disposed on the front surface or the back surface of the sanitary tissue directly subjected to the load in the thickness direction, the strength in the thickness direction of the entire sanitary tissue can be improved.

在第5方式中，端部片材由不具有上述非壓花部的上述第2片材構成。即，端部片材由僅具有壓花部的片材構成。僅具有該壓花部的第2片材構成以嵌套形式形成的一對片材的一部分，以嵌套形式形成的第2片材即使在僅具有壓花部的片材中相對於厚度方向的負荷的強度也更高。 In the fifth aspect, the end sheet is composed of the second sheet which does not have the non-embossed portion. That is, the end sheet is composed of a sheet having only an embossed portion. Only the second sheet having the embossed portion constitutes a part of a pair of sheets formed in a nested form, and the second sheet formed in a nested form is opposed to the thickness direction even in a sheet having only the embossed portion The strength of the load is also higher.

即，在第5方式中，在重疊方向的兩端部中的至少一端，配置有以嵌套形式形成的一對片材中不具有非壓花部的片材(僅具有壓花部的片材)。因此，在直接受到向厚度方向的負荷的衛生薄頁紙的正面或背面，可以配置相對於厚 度方向的負荷的強度更高的片材，因此可以進一步提高衛生薄頁紙整體的厚度方向的強度。 In other words, in the fifth aspect, at least one of the end portions in the overlapping direction is disposed with a sheet having no non-embossed portion among the pair of sheets formed in a nested form (a sheet having only the embossed portion) material). Therefore, a sheet having a higher strength with respect to the load in the thickness direction can be disposed on the front surface or the back surface of the sanitary tissue directly subjected to the load in the thickness direction, so that the strength in the thickness direction of the entire sanitary tissue can be further improved. .

在第6方式中，上述2片以上的片材分別具有2個以上的片材區域，在上述第1片材的該片材區域中的至少1個片材區域形成有具有上述非壓花部的非壓花區域，在上述第2片材的片材區域僅形成有不具有上述非壓花部的壓花區域。 In the sixth aspect, the two or more sheets each have two or more sheet regions, and the non-embossed portion is formed in at least one of the sheet regions of the first sheet. In the non-embossed region, only the embossed region having the non-embossed portion is formed in the sheet region of the second sheet.

片材區域是指將各片材劃分為任意的尺寸時被劃分的範圍，2片以上的片材分別具有2個以上的片材區域是指該劃分的範圍為2個以上。此外，壓花區域是指片材區域中不具有非壓花部的片材區域(僅具有壓花部的片材區域)，非壓花區域是指片材區域中具有非壓花部的片材區域(具有壓花部和非壓花部的片材區域)。另外，在至少1個片材區域形成有非壓花區域包含在2個以上的片材區域中一部分片材區域形成有非壓花區域、在另一部分的片材區域形成有壓花區域的情況以及在2個以上的片材區域的全部片材區域形成有非壓花區域的情況。 The sheet area is a range in which each sheet is divided into an arbitrary size, and two or more sheets each having two or more sheet areas means that the range of the division is two or more. Further, the embossed area refers to a sheet region (a sheet region having only an embossed portion) which does not have a non-embossed portion in the sheet region, and the non-embossed region refers to a sheet having a non-embossed portion in the sheet region. Material area (sheet area with embossed and non-embossed parts). Further, the non-embossed region is formed in at least one sheet region, and includes a non-embossed region in a part of the sheet region in the two or more sheet regions, and an embossed region in the sheet region of the other portion. And a case where a non-embossed area is formed in all the sheet areas of two or more sheet areas.

在第6方式中，在以這種方式劃分的片材區域中第1片材的至少1個片材區域形成的非壓花區域僅與形成於第2片材的壓花部相對。即，在一對片材之間的各區域，以非壓花部彼此不重疊的方式配置(不會形成非壓花空間)。因此，即使增加形成於第1片材的非壓花區域的面積，由於不存在非壓花空間，因此也可以維持對負荷的厚度方向的強度，能夠提高負荷時的吸收性能。此外，即使不存在非壓花空間，由於存在形成於第1片材的非壓花區域，也能夠抑制油分等的分散性的降低、維持設計性。 In the sixth aspect, the non-embossed region formed in at least one sheet region of the first sheet in the sheet region divided in this manner faces only the embossed portion formed on the second sheet. That is, each region between the pair of sheets is disposed such that the non-embossed portions do not overlap each other (the non-embossed space is not formed). Therefore, even if the area of the non-embossed area formed in the first sheet is increased, since there is no non-embossed space, the strength in the thickness direction of the load can be maintained, and the absorption performance at the time of load can be improved. In addition, even if there is no non-embossed space, it is possible to suppress a decrease in dispersibility of oil or the like and maintain designability because there is a non-embossed region formed on the first sheet.

在第7方式中，非壓花部由多個圖案形成。非壓花部的圖案為從相對的形成有壓花部的第2片材來看的形成於第1片材的非壓花部的輪廓形狀。藉由將非壓花部的圖案設為多個，能夠提高衛生薄頁紙的設計性。此外，由於形成於第1片材的非壓花區域增加，因此能夠提高油分等的分散性。 In the seventh aspect, the non-embossed portion is formed of a plurality of patterns. The pattern of the non-embossed portion is a contour shape of the non-embossed portion formed on the first sheet as viewed from the second sheet on which the embossed portion is formed. By designing a plurality of patterns of the non-embossed portions, the design of the sanitary tissue can be improved. Further, since the non-embossed region formed on the first sheet increases, the dispersibility of the oil component or the like can be improved.

在第8方式中，圖案中鄰接的2個圖案為360°/n旋轉對稱。此處，n為1以上的整數。此外，360°/n旋轉對稱是指在以虛擬軸為中心使圖案旋轉360°/n時，旋轉後的圖案與旋轉前的圖案重疊。另外，圖案的形狀沒有特別限定，可以採用圓形、三角形、四邊形、多邊形、十字形、心形等所有形狀。此外，構 成圖案的圖形的個數不限定於1個，也可以由多個圖形構成，此外，多個圖形可以為不同的形狀。 In the eighth aspect, the two adjacent patterns in the pattern are 360°/n rotationally symmetric. Here, n is an integer of 1 or more. Further, the 360°/n rotational symmetry means that when the pattern is rotated by 360°/n around the virtual axis, the rotated pattern overlaps with the pattern before the rotation. Further, the shape of the pattern is not particularly limited, and any shapes such as a circle, a triangle, a quadrangle, a polygon, a cross, and a heart may be employed. Further, the number of patterns constituting the pattern is not limited to one, and may be composed of a plurality of patterns, and the plurality of patterns may have different shapes.

以成為這種旋轉對稱的位置關係的方式將鄰接的2個圖案形成於第1片材，從而能夠在第1片材上規則地配置非壓花部。即，非壓花部的圖案在衛生薄頁紙整體可以呈現幾何花紋。因此，即使不存在非壓花空間，也能夠抑制油分等的分散性的降低，並且維持設計性。 By forming the two adjacent patterns on the first sheet so as to have such a rotationally symmetrical positional relationship, the non-embossed portions can be regularly arranged on the first sheet. That is, the pattern of the non-embossed portion can assume a geometric pattern on the entire sanitary tissue. Therefore, even if there is no non-embossed space, it is possible to suppress a decrease in dispersibility of oil or the like and maintain designability.

在第9方式中，多個圖案中鄰接的2個圖案為線對稱。線對稱是指在以假想的直線為軸使圖案反轉時，反轉後的圖案與反轉前的圖案重疊。藉由以成為這種線對稱的位置關係的方式將鄰接的2個圖案形成於第1片材，也能夠將非壓花部規則地配置於第1片材上(非壓花部的圖案在衛生薄頁紙整體可以呈現幾何花紋)，因此能夠抑制油分等的分散性的降低，並且維持設計性。 In the ninth aspect, two adjacent patterns among the plurality of patterns are line symmetrical. The line symmetry means that when the pattern is inverted with the virtual straight line as the axis, the inverted pattern overlaps with the pattern before the inversion. By forming the two adjacent patterns on the first sheet so as to have such a line-symmetric positional relationship, the non-embossed portions can be regularly arranged on the first sheet (the pattern of the non-embossed portion is Since the sanitary tissue as a whole can exhibit a geometric pattern), it is possible to suppress a decrease in dispersibility of oil or the like and maintain designability.

在第10方式中，上述非壓花部不具有交叉部。不具有交叉部是指在第1片材中沒有在非壓花部內交叉的部分、或者非壓花部彼此不交叉。藉由採用這種構成，不會形成有可能滯留非壓花部內的油分等的部分，因此能夠可靠地提高油分等的擴散性、減少油分等的透印。 In the tenth aspect, the non-embossed portion does not have an intersection portion. The absence of the intersection means that the portions that do not intersect in the non-embossed portion in the first sheet or the non-embossed portions do not intersect each other. By adopting such a configuration, it is possible to prevent a portion in which oil or the like in the non-embossed portion is retained, and it is possible to reliably improve the diffusibility of oil or the like and to reduce the offset of oil or the like.

在第11方式中，非壓花部的面積率成為3~16%。非壓花部的面積率是指第1片材(衛生薄頁紙)的表面所占的非壓花部的面積的比例。形成於第1片材的非壓花部的面積率優選為5~13%，更優選為6~11%。在非壓花部的面積率小於3%的情況下，有可能無法得到充分的油分等的分散性。此外，在非壓花部的面積率超過13%的情況下，由於壓花凸部的數量少，因此有可能無法得到負荷時的對厚度方向的充分的強度。 In the eleventh aspect, the area ratio of the non-embossed portion is 3 to 16%. The area ratio of the non-embossed portion refers to the ratio of the area of the non-embossed portion occupied by the surface of the first sheet (hygiene tissue). The area ratio of the non-embossed portion formed on the first sheet is preferably 5 to 13%, and more preferably 6 to 11%. When the area ratio of the non-embossed portion is less than 3%, sufficient dispersibility such as oil content may not be obtained. Further, when the area ratio of the non-embossed portion exceeds 13%, since the number of embossed convex portions is small, sufficient strength in the thickness direction at the time of load may not be obtained.

根據本發明的一個方式，可以提供一種維持吸收性、設計性，並且負荷時的吸收性能優異的衛生薄頁紙。 According to an aspect of the present invention, it is possible to provide a sanitary tissue which is excellent in absorbability and designability and which is excellent in absorbability at the time of load.

以下，一邊參照附圖一邊對本發明實施的方式詳細地進行說明。應予說明，有時對各個圖中通用的部分標記相同的符號而省略說明。圖1為表示本發明的實施方式(實施例1)所涉及的廚房紙的圖。圖2的(A)和(B)為表示構成圖1的廚房紙的第1片材和第2片材的圖。 Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the description of the drawings, the same reference numerals will be given to the same parts in the respective drawings, and the description will be omitted. Fig. 1 is a view showing a kitchen paper according to an embodiment (Example 1) of the present invention. (A) and (B) of FIG. 2 are views showing the first sheet and the second sheet constituting the kitchen paper of Fig. 1 .

如圖1和圖2所示，廚房紙100具有皺紋紙10和皺紋紙20。廚房紙100的形態沒有特別限定，可以使用將帶狀且以適當的間隔配置有分斷用的穿孔線的廚房紙捲繞在紙管上的卷型、或被稱為拾取式(pick up type)、抽取式(pop-up type)等的將單張廚房紙折疊層疊而成的層疊型。應予說明，廚房紙100為本發明的衛生薄頁紙的一個例子，皺紋紙10、20為構成本發明的衛生薄頁紙的第1 和第2片材的一個例子。 As shown in FIGS. 1 and 2, the kitchen paper 100 has crepe paper 10 and crepe paper 20. The form of the kitchen paper 100 is not particularly limited, and a roll type in which a kitchen paper in which a perforation line for separation is disposed in a strip shape at a proper interval is wound around a paper tube, or a pick up type can be used. A stacked type in which a single piece of kitchen paper is folded and laminated, such as a pop-up type. Incidentally, the kitchen paper 100 is an example of the sanitary tissue of the present invention, and the crepe papers 10 and 20 are examples of the first and second sheets constituting the sanitary tissue of the present invention.

皺紋紙10使用將原紙的原料以紙漿為主材的紙。紙漿組成可以使用廚房紙的習知的組成。例如，可以將紙漿的配合比例設為50品質%以上，優選為90品質%以上，更優選為100品質%。此外，皺紋紙20也可以使用與皺紋紙10相同的紙。 The crepe paper 10 uses paper in which the raw material of the base paper is made of pulp. The pulp composition can be made using the conventional composition of kitchen paper. For example, the blending ratio of the pulp may be 50% by mass or more, preferably 90% by mass or more, and more preferably 100% by mass. Further, the same paper as the crepe paper 10 can be used for the crepe paper 20.

紙漿組成例如可以將NBKP(針葉樹牛皮紙漿)、NUKP(針葉樹未漂白紙漿)等針葉樹紙漿以及LBKP(闊葉樹牛皮紙漿)、LUKP(闊葉樹未漂白紙漿)等闊葉樹紙漿以適當的比率使用。特別優選為與闊葉樹紙漿相比使針葉樹紙漿更多的組成的紙漿組成。針葉樹紙漿與闊葉樹紙漿之比優選為50：50~80：20。 For the pulp composition, for example, conifer pulp such as NBKP (conifer kraft pulp), NUKP (coniferous unbleached pulp), and hardwood pulp such as LBKP (broadleaf kraft pulp) and LUKP (broadleaf unbleached pulp) can be used at an appropriate ratio. It is particularly preferred to have a pulp composition which makes the conifer pulp more composed than the hardwood pulp. The ratio of conifer pulp to broadleaf pulp is preferably 50:50 to 80:20.

此外，皺紋紙10、20中，使用以JIS P 8124(1998)為基準的每平方米的重量為15~30g/m2的紙。若將皺紋紙10、20的每平方米的重量調整為該範圍，則水、油等液體與紙面接觸時，得到充分的液體擴散性，尤其是得到特別高的吸水性能。此外，該範圍內的每平方米的重量時，可得到作為廚房紙使用時的柔軟性、追隨性。 Further, in the crepe papers 10 and 20, paper having a weight per square meter of 15 to 30 g/m 2 based on JIS P 8124 (1998) is used. When the weight per square meter of the crepe papers 10 and 20 is adjusted to this range, when a liquid such as water or oil comes into contact with the paper surface, sufficient liquid diffusibility is obtained, and in particular, a particularly high water absorbing property is obtained. Moreover, the softness and followability at the time of use as a kitchen paper can be obtained by the weight per square meter in this range.

皺紋紙10中，在皺紋紙10的正面和背面形成多個壓花凸部EC和與壓花凸部EC對應的壓花凹部ED。各壓花凸部EC的頂部(或壓花凹部ED的開口部)在俯視時呈現四邊形狀。此外，壓花凸部EC(或壓花凹部ED)的側面從壓花凹部ED的底部向開口部以未圖示的錐形形成。 In the crepe paper 10, a plurality of embossed convex portions EC and embossed concave portions ED corresponding to the embossed convex portions EC are formed on the front and back surfaces of the crepe paper 10. The top of each embossed convex portion EC (or the opening portion of the embossed concave portion ED) has a quadrangular shape in plan view. Further, the side surface of the embossed convex portion EC (or the embossed concave portion ED) is formed from a bottom portion of the embossed concave portion ED toward the opening portion by a taper (not shown).

壓花凸部EC是藉由習知的鋼橡膠式的壓花賦予方法將未圖示的凸壓花輥按壓在皺紋紙10上，從而形成於皺紋紙10的一個面上，壓花凹部ED作為與壓花凸部EC對應的壓花凹部而形成於皺紋紙10的另一個面上。 The embossing convex portion EC is formed by pressing a embossing roller (not shown) on the crepe paper 10 by a conventional steel-rubber embossing method to form one surface of the crepe paper 10, and the embossed concave portion ED. The embossed concave portion corresponding to the embossed convex portion EC is formed on the other surface of the crepe paper 10.

皺紋紙10具有壓花部30和非壓花部50。壓花部30形成有多個壓花凸部EC和多個非壓花凸部NE。另一方面，在非壓花部50，多個壓花凸部EC和多個非壓花凸部NE均未形成。 The crepe paper 10 has an embossed portion 30 and a non-embossed portion 50. The embossed portion 30 is formed with a plurality of embossed convex portions EC and a plurality of non-embossed convex portions NE. On the other hand, in the non-embossed portion 50, a plurality of embossed convex portions EC and a plurality of non-embossed convex portions NE are not formed.

此處，非壓花凸部NE表示被多個壓花凸部EC包圍的未形成凸部的部分。應予說明，壓花部30和非壓花部50為構成本發明的衛生薄頁紙的一對片材中形成於第1片材的壓花部和非壓花部的一個例子。 Here, the non-embossed convex portion NE indicates a portion where the convex portion is not formed surrounded by the plurality of embossed convex portions EC. Incidentally, the embossed portion 30 and the non-embossed portion 50 are examples of the embossed portion and the non-embossed portion formed in the first sheet of the pair of sheets constituting the sanitary tissue of the present invention.

皺紋紙20中，在皺紋紙10的正面和背面形成有多個壓花凸部EC和與 壓花凸部EC對應的壓花凹部ED。各壓花凸部EC的頂部(或壓花凹部ED的開口部)在俯視時呈現四邊形狀。此外，壓花凸部EC(或壓花凹部ED)的側面從壓花凹部ED的底部向開口部以未圖示的錐形形成。壓花凸部EC與皺紋紙10同樣地藉由將凸壓花輥按壓在皺紋紙20上而形成於皺紋紙20的一個面上，壓花凹部ED作為與壓花凸部EC對應的壓花凹部而形成於皺紋紙20的另一個面上。 In the crepe paper 20, a plurality of embossed convex portions EC and embossed concave portions ED corresponding to the embossed convex portions EC are formed on the front and back surfaces of the crepe paper 10. The top of each embossed convex portion EC (or the opening portion of the embossed concave portion ED) has a quadrangular shape in plan view. Further, the side surface of the embossed convex portion EC (or the embossed concave portion ED) is formed from a bottom portion of the embossed concave portion ED toward the opening portion by a taper (not shown). The embossed convex portion EC is formed on one surface of the crepe paper 20 by pressing the convex embossing roll against the crepe paper 20 in the same manner as the crepe paper 10, and the embossed concave portion ED serves as an embossing corresponding to the embossed convex portion EC. A recess is formed on the other surface of the crepe paper 20.

皺紋紙20具有壓花部40，不具有非壓花部。壓花部40形成有多個壓花凸部EC和多個非壓花凸部NE。即，皺紋紙20僅形成有多個壓花凸部EC和多個非壓花凸部NE。此處，非壓花凸部NE表示被多個壓花凸部EC包圍的未形成凸部的部分。應予說明，壓花部40為構成本發明的衛生薄頁紙的一對片材中形成於第2片材上的壓花部和非壓花部的一個例子。 The crepe paper 20 has an embossed portion 40 and does not have a non-embossed portion. The embossed portion 40 is formed with a plurality of embossed convex portions EC and a plurality of non-embossed convex portions NE. That is, the crepe paper 20 is formed only with a plurality of embossed convex portions EC and a plurality of non-embossed convex portions NE. Here, the non-embossed convex portion NE indicates a portion where the convex portion is not formed surrounded by the plurality of embossed convex portions EC. The embossed portion 40 is an example of an embossed portion and a non-embossed portion formed on the second sheet of the pair of sheets constituting the sanitary tissue of the present invention.

在本實施方式的廚房紙100中，將皺紋紙10與皺紋紙20重疊，使壓花凸部EC、EC的形成面以嵌套形式相對而一體化。具體而言，皺紋紙10的壓花凸部EC與皺紋紙20的非壓花凸部NE(未設置有壓花凸部EC的部分)對置而配置。另一方面，皺紋紙20的壓花凸部EC與皺紋紙10的非壓花凸部NE(未設置有壓花凸部EC的部分)對置而配置。 In the kitchen paper 100 of the present embodiment, the crepe paper 10 is overlapped with the crepe paper 20, and the formation faces of the embossed convex portions EC and EC are opposed to each other in a nested form. Specifically, the embossed convex portion EC of the crepe paper 10 is disposed opposite to the non-embossed convex portion NE of the crepe paper 20 (portion where the embossed convex portion EC is not provided). On the other hand, the embossed convex portion EC of the crepe paper 20 is disposed opposite to the non-embossed convex portion NE of the crepe paper 10 (portion where the embossed convex portion EC is not provided).

此外，皺紋紙10的壓花凸部EC的頂部利用未圖示的黏接劑與皺紋紙20的非壓花凸部NE黏接。藉由使皺紋紙10的壓花凸部EC的頂部與皺紋紙20的非壓花凸部NE黏接，能夠將2片皺紋紙10、20的黏接部分平衡良好地配置於一個皺紋紙(皺紋紙10)側。因此，能夠減少由黏接劑所致的吸收性能的降低。 Further, the top of the embossed convex portion EC of the crepe paper 10 is adhered to the non-embossed convex portion NE of the crepe paper 20 by an adhesive (not shown). By bonding the top of the embossed convex portion EC of the crepe paper 10 to the non-embossed convex portion NE of the crepe paper 20, the adhesive portions of the two crepe papers 10 and 20 can be placed in a crepe paper in a well-balanced manner ( Wrinkled paper 10) side. Therefore, the decrease in the absorption performance by the adhesive can be reduced.

另外，黏接劑可以使用具有層疊結構的廚房紙所採用的習知的黏接劑。作為這種黏接劑，例如有聚乙烯醇、澱粉、改性澱粉、羧甲基纖維素等纖維素系黏接劑等。 Further, as the adhesive, a conventional adhesive used for kitchen paper having a laminated structure can be used. Examples of such an adhesive include cellulose-based adhesives such as polyvinyl alcohol, starch, modified starch, and carboxymethylcellulose.

另外，也可以將皺紋紙20的壓花凸部EC的頂部與皺紋紙10的非壓花凸部NE黏接來代替將皺紋紙10的壓花凸部EC的頂部與皺紋紙20的非壓花凸部NE黏接。此外，也可以將皺紋紙10的壓花凸部EC的頂部與皺紋紙20的非壓花凸部NE黏接且將皺紋紙20的壓花凸部EC的頂部與皺紋紙10的非壓花凸部NE黏接。 Alternatively, the top of the embossed convex portion EC of the crepe paper 20 may be bonded to the non-embossed convex portion NE of the crepe paper 10 instead of the non-pressure of the top of the embossed convex portion EC of the crepe paper 10 and the crepe paper 20. The flower convex part NE is bonded. Further, the top of the embossed convex portion EC of the crepe paper 10 may be adhered to the non-embossed convex portion NE of the crepe paper 20 and the top of the embossed convex portion EC of the crepe paper 20 and the non-embossed crepe paper 10 may be The convex portion NE is bonded.

在本實施方式中，如圖1所示，皺紋紙10的壓花部30和非壓花部50是以與皺紋紙20的壓花部40相對的方式在皺紋紙10形成有壓花部30和非壓花部50、在皺紋紙20僅形成有壓花部40。藉由採用這種結構，在皺紋紙10與皺紋紙20之間，非壓花部彼此不相對，因此在皺紋紙10與皺紋紙20之間不會形成容易壓扁的非壓花空間。因此，根據本實施方式，能夠提高廚房紙100的對負荷的厚度方向的強度，因此能夠提高負荷時的吸收性能(例如，降低廚房紙100的油分等的透印)。 In the present embodiment, as shown in FIG. 1, the embossed portion 30 and the non-embossed portion 50 of the crepe paper 10 are formed with the embossed portion 30 on the crepe paper 10 so as to face the embossed portion 40 of the crepe paper 20. The embossed portion 40 is formed with only the embossed portion 40 on the crepe paper 20. By adopting such a configuration, the non-embossed portions are not opposed to each other between the crepe paper 10 and the crepe paper 20, so that a non-embossed space which is easily crushed is not formed between the crepe paper 10 and the crepe paper 20. Therefore, according to the present embodiment, the strength of the kitchen paper 100 in the thickness direction of the load can be increased, so that the absorption performance at the time of load (for example, the offset of the oil content of the kitchen paper 100 or the like) can be improved.

此外，即使是在皺紋紙10與皺紋紙20之間非壓花部彼此不相對的結構，由於非壓花部50配置於廚房紙100內，因此油分等也可以在廚房紙100內介由非壓花部50進行擴散。因此，根據本實施方式，即使不形成非壓花空間，也能夠維持吸收的油分等的擴散性。 Further, even if the non-embossed portions are not opposed to each other between the crepe paper 10 and the crepe paper 20, since the non-embossed portion 50 is disposed in the kitchen paper 100, the oil or the like may be interposed in the kitchen paper 100. The embossed portion 50 is diffused. Therefore, according to the present embodiment, even if the non-embossed space is not formed, the diffusibility of the absorbed oil or the like can be maintained.

此外，如本實施方式那樣在皺紋紙10與皺紋紙20之間不存在非壓花空間的結構中，當然也不存在非壓花空間交叉的交叉部(容易滯留油分等的部分)，因此，根據本實施方式，能夠提高油分等的擴散性、降低油分等的透印。 Further, in the configuration in which the non-embossed space is not present between the crepe paper 10 and the crepe paper 20 as in the present embodiment, of course, there is no intersection portion where the non-embossed space intersects (the portion where oil or the like is easily retained), and therefore, According to the present embodiment, it is possible to improve the diffusibility of the oil component or the like and to reduce the offset of the oil component or the like.

此外，在本實施方式中，非壓花部50配置於廚房紙100內，因此即使不形成非壓花空間，也能夠維持設計性。 Further, in the present embodiment, since the non-embossed portion 50 is disposed in the kitchen paper 100, the design property can be maintained without forming a non-embossed space.

此外，在本實施方式中，由於採用嵌套形式的層疊結構，且具有僅形成有不具有非壓花部的壓花部的片材，因此能夠減小廚房紙100的與使用物件(例如，餐具、油炸食品等)的接觸面積，即使在使用時施加負荷，廚房紙100內的空間也難以壓扁。因此，根據本實施方式，能夠提高負荷時的吸收性能，並且減小皺紋紙10、20的每平方米的重量、紙厚，能夠減薄廚房紙100的厚度。 Further, in the present embodiment, since the laminated structure in the nested form is used and the sheet having only the embossed portion having no non-embossed portion is formed, it is possible to reduce the use of the kitchen sheet 100 and the use of the article (for example, The contact area of the tableware, the fried food, and the like is hard to be crushed even if a load is applied during use. Therefore, according to the present embodiment, the absorption performance at the time of load can be improved, and the weight per unit square of the crepe papers 10 and 20 and the paper thickness can be reduced, and the thickness of the kitchen paper 100 can be reduced.

此外，在本實施方式中，位於皺紋紙10、20中重疊方向的兩端部的一端(將重疊方向放置成上下方向時的最上端)的皺紋紙(端部片材)由具有非壓花部50的皺紋紙10構成。即，在廚房紙100的表面配置有形成了未形成多個壓花凸部EC和多個非壓花凸部的非壓花部的片材。 Further, in the present embodiment, the crepe paper (end sheet) which is located at one end of both ends of the crepe papers 10 and 20 in the overlapping direction (the uppermost end when the overlapping direction is placed in the vertical direction) is made of non-embossed The crepe paper 10 of the portion 50 is constructed. That is, a sheet on which the non-embossed portions in which the plurality of embossed convex portions EC and the plurality of non-embossed convex portions are not formed are formed on the surface of the kitchen paper 100 are disposed.

本實施方式中，具有非壓花部50的皺紋紙10位於片材的重疊方向的最上端，因此具有可發揮設計性的非壓花部50的皺紋紙10被配置於廚房紙100的表面。因此，廚房紙100的從外部來看的辨識性良好。 In the present embodiment, since the crepe paper 10 having the non-embossed portion 50 is located at the uppermost end in the overlapping direction of the sheet, the crepe paper 10 having the non-embossed portion 50 capable of exhibiting design is disposed on the surface of the kitchen paper 100. Therefore, the visibility of the kitchen paper 100 from the outside is good.

此外，皺紋紙10構成與皺紋紙20以嵌套形式重疊的一對片材的一部分，此外，以嵌套形式形成的一對皺紋紙的對厚度方向的負荷的強度高。在本實施方式中，在直接受到向厚度方向的負荷的廚房紙100的表面配置有具有非壓花部50的皺紋紙10，因此即使在廚房紙100的內部不存在非壓花空間的情況下，也能夠提高廚房紙100的對負荷的厚度方向的強度，並且維持設計性。 Further, the crepe paper 10 constitutes a part of a pair of sheets which are overlapped with the crepe paper 20 in a nested form, and the strength of the load in the thickness direction of the pair of crepe papers formed in a nested form is high. In the present embodiment, the crepe paper 10 having the non-embossed portion 50 is disposed on the surface of the kitchen paper 100 directly subjected to the load in the thickness direction. Therefore, even if there is no non-embossed space inside the kitchen paper 100, It is also possible to increase the strength of the kitchen paper 100 in the thickness direction of the load and maintain the design.

此外，在本實施方式中，位於皺紋紙10、20中重疊方向的兩端部的一端(將重疊方向放置成上下方向時的最下端)的皺紋紙(端部片材)由不具有非壓花部的皺紋紙20構成。即，在廚房紙100的背面僅配置了形成有多個壓花凸部EC和多個非壓花凸部NE的壓花部40。 Further, in the present embodiment, the crepe paper (end sheet) which is located at one end of both ends of the crepe papers 10 and 20 in the overlapping direction (the lowermost end when the overlapping direction is placed in the vertical direction) has no non-pressure. The crepe paper 20 of the flower part is composed. That is, only the embossed portion 40 in which the plurality of embossed convex portions EC and the plurality of non-embossed convex portions NE are formed is disposed on the back surface of the kitchen paper 100.

在本實施方式中，僅具有壓花部40(不具有非壓花部)的皺紋紙20位於片材的重疊方向的最下端，因此能夠在直接受到向厚度方向的負荷的廚房紙100的背面配置對厚度方向的負荷的強度高的皺紋紙，因此能夠提高廚房紙100的厚度方向的強度。 In the present embodiment, only the crepe paper 20 having the embossed portion 40 (having no non-embossed portion) is located at the lowermost end in the overlapping direction of the sheet, and therefore can be directly received on the back surface of the kitchen paper 100 in the load in the thickness direction. Since the crepe paper having high strength against the load in the thickness direction is disposed, the strength of the kitchen paper 100 in the thickness direction can be improved.

此外，皺紋紙20構成與皺紋紙10以嵌套形式重疊的一對片材的一部分，此外，以嵌套形式形成的一對皺紋紙的對厚度方向的負荷的強度高。在本實施方式中，在直接受到向厚度方向的負荷的廚房紙100的背面，配置有僅具有壓花部40(不具有非壓花部的)的皺紋紙20，因此可以在直接受到向厚度方向的負荷的廚房紙100的背面配置對厚度方向的負荷的強度更高的皺紋紙，由此能夠可靠地提高廚房紙100的厚度方向的強度。 Further, the crepe paper 20 constitutes a part of a pair of sheets which are overlapped with the crepe paper 10 in a nested form, and the strength of the load in the thickness direction of the pair of crepe papers formed in a nested form is high. In the present embodiment, the crepe paper 20 having only the embossed portion 40 (having no non-embossed portion) is disposed on the back surface of the kitchen paper 100 directly subjected to the load in the thickness direction, so that the thickness can be directly received. The crepe paper having a higher strength against the load in the thickness direction is disposed on the back surface of the kitchen paper 100 in the direction of the load, whereby the strength in the thickness direction of the kitchen paper 100 can be reliably improved.

此外，在本實施方式中，廚房紙100具有2個以上的區域，構成廚房紙100的皺紋紙10、20分別具有2個以上的區域(片材區域)。如圖2(A)所示，在皺紋紙10的片材區域(第1片材區域11、第2片材區域12、第3片材區域13和第4片材區域14)形成有不具有非壓花部50的區域和具有非壓花部50的區域。另一方面，如圖2(B)所示，在皺紋紙20的片材區域(第5片材區域21、第6片材區域22、第7片材區域23和第8片材區域24)僅形成有不具有非壓花部的區域。即，具有非壓花部50的區域以與不具有非壓花部的區域重疊的方式配置。 Further, in the present embodiment, the kitchen paper 100 has two or more regions, and the crepe papers 10 and 20 constituting the kitchen paper 100 each have two or more regions (sheet regions). As shown in FIG. 2(A), the sheet region (the first sheet region 11, the second sheet region 12, the third sheet region 13, and the fourth sheet region 14) of the crepe paper 10 is formed without The area of the non-embossed portion 50 and the region having the non-embossed portion 50. On the other hand, as shown in FIG. 2(B), in the sheet region of the crepe paper 20 (the fifth sheet region 21, the sixth sheet region 22, the seventh sheet region 23, and the eighth sheet region 24) Only regions having no non-embossed portions are formed. That is, the region having the non-embossed portion 50 is disposed so as to overlap with the region having no non-embossed portion.

具體而言，如圖1所示，廚房紙100具有能夠劃分成4個區域的區域70。該區域70可以劃分為第1區域71~第4區域74。區域70中，在第1區域71、 第3區域73配置有皺紋紙10的壓花部30和皺紋紙20的壓花部40，在第2區域72、第4區域74配置有皺紋紙10的非壓花部50和皺紋紙20的壓花部40。 Specifically, as shown in FIG. 1, the kitchen paper 100 has a region 70 that can be divided into four regions. This area 70 can be divided into the first area 71 to the fourth area 74. In the region 70, the embossed portion 30 of the crepe paper 10 and the embossed portion 40 of the crepe paper 20 are disposed in the first region 71 and the third region 73, and the crepe paper 10 is disposed in the second region 72 and the fourth region 74. The embossed portion 50 and the embossed portion 40 of the crepe paper 20.

將皺紋紙10的壓花部30劃分為第1壓花區域31~第4壓花區域34，將皺紋紙10的非壓花部50劃分為第2非壓花區域52和第4非壓花區域54，將皺紋紙20的壓花部40劃分為第1壓花區域41~第4壓花區域44。如此，在廚房紙100的4個區域中，在第1區域71中，皺紋紙10的第1壓花區域31與皺紋紙20的第1壓花區域41相對，在第2區域72中，皺紋紙10的第2非壓花區域52與皺紋紙20的第2壓花區域42相對，在第3區域73中，皺紋紙10的第3壓花區域33與皺紋紙20的第3壓花區域43相對，在第4區域74中，皺紋紙10的第4非壓花區域54與皺紋紙20的第4壓花區域44相對。 The embossed portion 30 of the crepe paper 10 is divided into a first embossed region 31 to a fourth embossed region 34, and the non-embossed portion 50 of the crepe paper 10 is divided into a second non-embossed region 52 and a fourth non-embossed portion. In the region 54, the embossed portion 40 of the crepe paper 20 is divided into a first embossed region 41 to a fourth embossed region 44. As described above, in the four regions of the kitchen paper 100, in the first region 71, the first embossed region 31 of the crepe paper 10 faces the first embossed region 41 of the crepe paper 20, and in the second region 72, wrinkles The second non-embossed region 52 of the paper 10 faces the second embossed region 42 of the crepe paper 20, and in the third region 73, the third embossed region 33 of the crepe paper 10 and the third embossed region of the crepe paper 20 In the fourth region 74, the fourth non-embossed region 54 of the crepe paper 10 faces the fourth embossed region 44 of the crepe paper 20.

在本實施方式中，皺紋紙10的非壓花部50配置於第2、第4區域72、74，在皺紋紙20未形成非壓花部。在這種構成中，配置於廚房紙100的4個區域中2個區域的非壓花部50的非壓花區域52、54由於在皺紋紙10與皺紋紙20之間非壓花部彼此不相對，因此不會形成非壓花部相對而形成的非壓花空間(容易壓扁的空間)。因此，能夠增加形成在皺紋紙10上的非壓花部50的非壓花區域的面積，能夠提高對負荷的厚度方向的強度，因此能夠提高負荷時的吸收性能。此外，即使增加形成在皺紋紙10上的非壓花部50的非壓花區域的面積，由於不存在非壓花空間，因此也可以較高地維持負荷時的吸收性能，並且抑制油分等的分散性的降低、維持設計性。 In the present embodiment, the non-embossed portion 50 of the crepe paper 10 is disposed in the second and fourth regions 72 and 74, and the non-embossed portion is not formed on the crepe paper 20. In such a configuration, the non-embossed regions 52 and 54 of the non-embossed portion 50 disposed in two of the four regions of the kitchen paper 100 are not embossed between the crepe paper 10 and the crepe paper 20. In contrast, a non-embossed space (a space that is easily crushed) formed without opposing the embossed portions is not formed. Therefore, the area of the non-embossed region of the non-embossed portion 50 formed on the crepe paper 10 can be increased, and the strength in the thickness direction of the load can be increased, so that the absorption performance at the time of load can be improved. Further, even if the area of the non-embossed area of the non-embossed portion 50 formed on the crepe paper 10 is increased, since there is no non-embossed space, the absorption performance at the time of load can be maintained high, and the dispersion of oil or the like can be suppressed. Reduced sexuality and maintain design.

圖3為表示本實施方式中後述的實施例2所涉及的廚房紙的圖。圖4的(A)和(B)為表示構成圖3的廚房紙的皺紋紙的圖。圖3的例子中，廚房紙100的4個區域70中，第1區域71~第4區域74均配置有皺紋紙10的非壓花部50和皺紋紙20的壓花部40。 FIG. 3 is a view showing the kitchen paper according to the second embodiment to be described later in the embodiment. 4(A) and 4(B) are views showing crepe paper constituting the kitchen paper of Fig. 3. In the example of FIG. 3, among the four regions 70 of the kitchen paper 100, the non-embossed portion 50 of the crepe paper 10 and the embossed portion 40 of the crepe paper 20 are disposed in each of the first region 71 to the fourth region 74.

將皺紋紙10的非壓花部50劃分為第1非壓花區域51~第4非壓花區域54，將皺紋紙20的壓花部40劃分為第1壓花區域41~第4壓花區域44。如此，在廚房紙100的4個區域中，在第1區域71中，皺紋紙10的第1非壓花區域51與皺紋紙20的第1壓花區域41相對，第2區域72中，皺紋紙10的第2非壓花區域52與皺紋紙20的第2壓花區域42相對，第3區域73中，皺紋紙10的第3非壓花區域53與皺紋紙20的第3壓花區域43相對，第4區域74中， 皺紋紙10的第4非壓花區域54與皺紋紙20的第4壓花區域44相對。 The non-embossed portion 50 of the crepe paper 10 is divided into a first non-embossed region 51 to a fourth non-embossed region 54, and the embossed portion 40 of the crepe paper 20 is divided into a first embossed region 41 to a fourth embossed portion. Area 44. As described above, in the four regions of the kitchen paper 100, in the first region 71, the first non-embossed region 51 of the crepe paper 10 faces the first embossed region 41 of the crepe paper 20, and the wrinkles in the second region 72 The second non-embossed region 52 of the paper 10 faces the second embossed region 42 of the crepe paper 20, and the third non-embossed region 53 of the crepe paper 10 and the third embossed region of the crepe paper 20 in the third region 73 In the fourth region 74, the fourth non-embossed region 54 of the crepe paper 10 faces the fourth embossed region 44 of the crepe paper 20.

在圖3的實施方式中，在廚房紙100的第1區域71~第4區域74配置有皺紋紙10的非壓花部50，在皺紋紙20未形成非壓花部。在這種構成中，配置於廚房紙100的4個區域中全部區域內的非壓花部50的非壓花區域51~54由於在皺紋紙10與皺紋紙20之間非壓花部彼此不相對，因此不會形成非壓花部相對而形成的非壓花空間(容易壓扁的空間)。因此，能夠增加形成在皺紋紙10上的非壓花部50的非壓花區域的面積，能夠提高對負荷的厚度方向的強度，因此能夠進一步提高負荷時的吸收性能。此外，圖3的例子中，由於也不存在非壓花空間，因此藉由使形成於皺紋紙10的非壓花部50的非壓花區域的面積增加，從而可以較高地維持負荷時的吸收性能，並且進一步抑制油分等的分散性的降低、進一步維持設計性。 In the embodiment of FIG. 3, the non-embossed portion 50 of the crepe paper 10 is disposed in the first region 71 to the fourth region 74 of the kitchen paper 100, and the non-embossed portion is not formed in the crepe paper 20. In such a configuration, the non-embossed regions 51 to 54 of the non-embossed portion 50 disposed in all of the four regions of the kitchen paper 100 are not embossed between the crepe paper 10 and the crepe paper 20. In contrast, a non-embossed space (a space that is easily crushed) formed without opposing the embossed portions is not formed. Therefore, the area of the non-embossed region of the non-embossed portion 50 formed on the crepe paper 10 can be increased, and the strength in the thickness direction of the load can be increased, so that the absorption performance at the time of load can be further improved. Further, in the example of Fig. 3, since there is no non-embossed space, the area of the non-embossed region formed in the non-embossed portion 50 of the crepe paper 10 is increased, so that the absorption at the time of load can be maintained high. The performance is further suppressed, and the dispersibility of the oil component or the like is further suppressed, and the design property is further maintained.

在本實施方式中，如圖1和圖3所示，皺紋紙10的非壓花部50由多個圖案形成。非壓花部50的圖案為從相對的形成有壓花部40的皺紋紙20來看的形成在皺紋紙10上的非壓花部50的輪廓形狀。具體而言，在皺紋紙10的非壓花區域52形成有1個圖案，在皺紋紙10的非壓花區域54形成有另一個圖案。藉由以這種方式使非壓花部50的圖案為多個，從而能夠提高衛生薄頁紙的設計性。此外，由於形成於第1片材的非壓花區域增加，因此能夠提高油分等的分散性。 In the present embodiment, as shown in FIGS. 1 and 3, the non-embossed portion 50 of the crepe paper 10 is formed of a plurality of patterns. The pattern of the non-embossed portion 50 is a contour shape of the non-embossed portion 50 formed on the crepe paper 10 as seen from the crepe paper 20 on which the embossed portion 40 is formed. Specifically, one pattern is formed in the non-embossed region 52 of the crepe paper 10, and another pattern is formed in the non-embossed region 54 of the crepe paper 10. By designing a plurality of patterns of the non-embossed portion 50 in this manner, the design of the sanitary tissue can be improved. Further, since the non-embossed region formed on the first sheet increases, the dispersibility of the oil component or the like can be improved.

此外，在本實施方式中，形成於皺紋紙10的多個非壓花部50的圖案為360°/n旋轉對稱。此處，n為1以上的整數。具體而言，圖1和圖2的例子中，形成於非壓花區域52的圖案和形成於非壓花區域54的圖案為180°旋轉對稱。此外，圖3和圖4的例子中，形成於非壓花區域51、52的圖案與形成於非壓花區域53、54的圖案為180°旋轉對稱。 Further, in the present embodiment, the pattern of the plurality of non-embossed portions 50 formed on the crepe paper 10 is 360°/n rotationally symmetrical. Here, n is an integer of 1 or more. Specifically, in the examples of FIGS. 1 and 2, the pattern formed in the non-embossed region 52 and the pattern formed in the non-embossed region 54 are 180° rotationally symmetric. Further, in the examples of FIGS. 3 and 4, the patterns formed in the non-embossed regions 51, 52 and the patterns formed in the non-embossed regions 53, 54 are 180 degrees rotationally symmetric.

另外，非壓花部的圖案的形狀是任意的。在本實施方式中，在圖1的例子中，如圖1和圖2所示，圖案的形狀為十字形。此外，在圖3的例子中，如圖3和圖5所示，在各非壓花區域51~54中，圖案的形狀為長方形。進而，在圖3的例子中，在非壓花區域51、53形成有四個圖案，在非壓花區域52、54形成有12個圖案。 Further, the shape of the pattern of the non-embossed portion is arbitrary. In the present embodiment, in the example of Fig. 1, as shown in Figs. 1 and 2, the shape of the pattern is a cross. Further, in the example of FIG. 3, as shown in FIGS. 3 and 5, in each of the non-embossed regions 51 to 54, the shape of the pattern is a rectangle. Further, in the example of Fig. 3, four patterns are formed in the non-embossed regions 51, 53, and twelve patterns are formed in the non-embossed regions 52, 54.

藉由作為具有成為這種旋轉對稱的位置關係的圖案的皺紋紙10的非壓 花部50的圖案而形成，能夠在皺紋紙10與皺紋紙20之間規則地配置非壓花部50。即，如圖1、圖3所示，非壓花部50的圖案從廚房紙100的整體來看時，可以呈現幾何花紋。因此，即使不設置非壓花空間，也能夠抑制油分等的分散性的降低、維持設計性。 The non-embossed portion 50 can be regularly disposed between the crepe paper 10 and the crepe paper 20 by being formed as a pattern of the non-embossed portion 50 of the crepe paper 10 having the pattern of such rotationally symmetrical positional relationship. That is, as shown in FIGS. 1 and 3, the pattern of the non-embossed portion 50 can be geometrically patterned when viewed from the entirety of the kitchen paper 100. Therefore, even if the non-embossed space is not provided, it is possible to suppress the decrease in the dispersibility of the oil component or the like and maintain the design property.

此外，如果改變觀看方式，則在本實施方式中，如圖1和圖3所示，形成於皺紋紙10的多個非壓花部50的圖案為線對稱。具體而言，在圖1和圖2的例子中，形成於非壓花區域52的圖案和形成於非壓花區域54的圖案為線物件。此外，在圖3和圖4的例子中，形成於非壓花區域51、52的圖案和形成於非壓花區域53、54內的圖案為線對稱。 Further, if the viewing mode is changed, in the present embodiment, as shown in FIGS. 1 and 3, the pattern of the plurality of non-embossed portions 50 formed on the crepe paper 10 is line symmetrical. Specifically, in the examples of FIGS. 1 and 2, the pattern formed in the non-embossed region 52 and the pattern formed in the non-embossed region 54 are line objects. Further, in the examples of FIGS. 3 and 4, the patterns formed in the non-embossed regions 51, 52 and the patterns formed in the non-embossed regions 53, 54 are line symmetrical.

藉由將具有成為這種線對稱的位置關係的圖案的非壓花部50形成於皺紋紙10，也可以在皺紋紙10與皺紋紙20之間不形成非壓花空間，而規則地配置非壓花部50，因此能夠可靠地抑制油分等的分散性的降低、維持設計性。 By forming the non-embossed portion 50 having the pattern having such a line-symmetric positional relationship on the crepe paper 10, a non-embossed space may not be formed between the crepe paper 10 and the crepe paper 20, and the non-embossed space may be regularly arranged. Since the embossed portion 50 can reliably suppress the decrease in dispersibility of oil or the like and maintain designability.

在本實施方式中，皺紋紙10的非壓花部50和皺紋紙20的非壓花部60成為不具有交叉部的構成。即，在皺紋紙10的非壓花部50內沒有非壓花部彼此交叉的部分。例如，在圖1的例子中，在可成為皺紋紙10的非壓花部50的交叉部的部分形成有壓花凸部NC。此外，在圖3的例子中，由於非壓花部的圖案為多個獨立的長方形的圖案，因此非壓花部彼此不會交叉。 In the present embodiment, the non-embossed portion 50 of the crepe paper 10 and the non-embossed portion 60 of the crepe paper 20 have a configuration without an intersection portion. That is, in the non-embossed portion 50 of the crepe paper 10, there is no portion where the non-embossed portions cross each other. For example, in the example of Fig. 1, an embossed convex portion NC is formed at a portion where the non-embossed portion 50 of the crepe paper 10 can be formed. Further, in the example of FIG. 3, since the pattern of the non-embossed portion is a plurality of independent rectangular patterns, the non-embossed portions do not cross each other.

藉由設為這種不具有交叉部的結構，從而在非壓花部50、60內不存在有可能滯留油分等的交叉部，因此能夠可靠地提高油分等的擴散性、減少油分等的透印。 By having such a configuration that does not have an intersection portion, there is no intersection portion in which the oil or the like may remain in the non-embossed portions 50 and 60. Therefore, it is possible to reliably improve the diffusibility of the oil component and the like, and to reduce the penetration of oil and the like. Printed.

此外，在本實施方式中，皺紋紙10的非壓花部50和皺紋紙20的非壓花部60的面積率(在形成有非壓花部的片材表面所占的非壓花部的面積的比例)為3~16%，優選為5~13%，更優選為6~11%。在非壓花部50、60的面積率小於3%時，有可能無法得到充分的油分等的分散性。此外，在非壓花部50、60的面積率超過13%的情況下，由於壓花凸部的數量少，因此有可能無法得到負荷時的對厚度方向的充分的強度。 Further, in the present embodiment, the area ratio of the non-embossed portion 50 of the crepe paper 10 and the non-embossed portion 60 of the crepe paper 20 (the non-embossed portion occupied by the surface of the sheet on which the non-embossed portion is formed) The ratio of the area is 3 to 16%, preferably 5 to 13%, and more preferably 6 to 11%. When the area ratio of the non-embossed portions 50 and 60 is less than 3%, sufficient dispersibility such as oil content may not be obtained. Further, when the area ratio of the non-embossed portions 50 and 60 exceeds 13%, since the number of embossed convex portions is small, sufficient strength in the thickness direction at the time of load may not be obtained.

此外，圖5和圖6為表示本實施方式(實施例3)所涉及的廚房紙的圖。在皺紋紙10未形成非壓花部，在皺紋紙20形成有非壓花部60。在這種構成中， 皺紋紙10、20中位於重疊方向的兩端部的一端(將重疊方向放置成上下方向時的最下端)的皺紋紙(端部片材)由具有非壓花部60的皺紋紙20構成。即，在廚房紙100的背面配置有形成了未形成多個壓花凸部EC和多個非壓花凸部的非壓花部的片材。 In addition, FIG. 5 and FIG. 6 are views showing the kitchen paper according to the embodiment (Example 3). A non-embossed portion is not formed on the crepe paper 10, and a non-embossed portion 60 is formed on the crepe paper 20. In such a configuration, the crepe paper (end sheet) of the one end portions of the crepe papers 10 and 20 located at the both end portions in the overlapping direction (the lowermost end when the overlapping direction is placed in the vertical direction) has the non-embossed portion 60. The crepe paper 20 is constructed. That is, a sheet on which the non-embossed portions in which the plurality of embossed convex portions EC and the plurality of non-embossed convex portions are not formed are formed on the back surface of the kitchen paper 100 are disposed.

在本實施方式中，由於具有非壓花部60的皺紋紙20位於片材的重疊方向的最下端，因此具有可發揮設計性的非壓花部60的皺紋紙20配置於廚房紙100的背面。因此，廚房紙100的從外部來看的辨識性良好。 In the present embodiment, since the crepe paper 20 having the non-embossed portion 60 is located at the lowermost end in the overlapping direction of the sheet, the crepe paper 20 having the non-embossed portion 60 that can exhibit the design property is disposed on the back surface of the kitchen paper 100. . Therefore, the visibility of the kitchen paper 100 from the outside is good.

此外，圖7和圖8為表示本實施方式(實施例4)所涉及的廚房紙的圖，圖9和圖10為表示本實施方式(實施例5)所涉及的廚房紙的圖，圖11和圖12為表示本實施方式(實施例6)所涉及的廚房紙的圖，圖13和圖14為表示本發明的實施方式(實施例7)所涉及的廚房紙的圖。 7 and 8 are views showing a kitchen paper according to the present embodiment (Example 4), and Figs. 9 and 10 are views showing a kitchen paper according to the present embodiment (Example 5), and Fig. 11 FIG. 12 is a view showing the kitchen paper according to the embodiment (the sixth embodiment), and FIGS. 13 and 14 are views showing the kitchen paper according to the embodiment (the seventh embodiment) of the present invention.

這些圖7~圖14所示的廚房紙100均將3片皺紋紙進行重疊而一體化。具體而言，除皺紋紙10和皺紋紙20以外，進一步重疊皺紋紙110或皺紋紙120而一體化。例如，圖7和圖8的例子中，在皺紋紙10形成有非壓花部50，在皺紋紙20和皺紋紙110未形成非壓花部。 Each of the kitchen sheets 100 shown in FIGS. 7 to 14 has three sheets of crepe paper stacked and integrated. Specifically, in addition to the crepe paper 10 and the crepe paper 20, the crepe paper 110 or the crepe paper 120 is further superposed and integrated. For example, in the example of FIGS. 7 and 8, the non-embossed portion 50 is formed on the crepe paper 10, and the non-embossed portion is not formed on the crepe paper 20 and the crepe paper 110.

此外，在圖9和圖10的例子中，在皺紋紙10和皺紋紙20形成有非壓花部50和非壓花部60，在皺紋紙110未形成非壓花部。 Further, in the examples of FIGS. 9 and 10, the crepe paper 10 and the crepe paper 20 are formed with the non-embossed portion 50 and the non-embossed portion 60, and the crepe paper 110 is not formed with the non-embossed portion.

此外，在圖11和圖12的例子中，在皺紋紙10未形成非壓花部，在皺紋紙20和皺紋紙120形成有非壓花部60和非壓花部160。 Further, in the example of FIGS. 11 and 12, the non-embossed portion is not formed on the crepe paper 10, and the non-embossed portion 60 and the non-embossed portion 160 are formed on the crepe paper 20 and the crepe paper 120.

此外，在圖13和圖14的例子中，在皺紋紙10形成有非壓花部50，在皺紋紙20未形成非壓花部，在皺紋紙120形成有非壓花部160。 Further, in the example of FIGS. 13 and 14, the non-embossed portion 50 is formed on the crepe paper 10, the non-embossed portion is not formed on the crepe paper 20, and the non-embossed portion 160 is formed on the crepe paper 120.

在這些圖7~14所示的廚房紙100中，重疊的3片皺紋紙中形成有非壓花部的皺紋紙和未形成非壓花部的皺紋紙均以嵌套形式層疊，因此在以嵌套形式層疊的皺紋紙之間不會形成容易壓扁的非壓花空間。因此，即使在將3片皺紋紙重疊而一體化的情況下，也能夠提高廚房紙100的對負荷的厚度方向的強度，因此能夠提高負荷時的吸收性能。此外，即使在以嵌套形式層疊的皺紋紙之間不存在非壓花空間，也可以由於非壓花部的存在而維持吸收的油分等的擴散性。 In the kitchen paper 100 shown in these FIGS. 7 to 14, the crepe paper in which the non-embossed portion is formed and the crepe paper in which the non-embossed portion is not formed in the three sheets of crepe paper which are overlapped are stacked in a nested manner, so A non-embossed space that is easily crushed is not formed between the crepe papers stacked in a nested form. Therefore, even when three sheets of crepe paper are superposed and integrated, the strength of the kitchen paper 100 in the thickness direction of the load can be improved, so that the absorption performance at the time of load can be improved. Further, even if there is no non-embossed space between the crepe papers stacked in a nested form, the diffusibility of the absorbed oil or the like can be maintained due to the presence of the non-embossed portion.

此外，在圖7、圖9和圖13的例子中，3片皺紋紙中位於重疊方向的最上端的皺紋紙(端部片材)由具有非壓花部50的皺紋紙10構成。此外，在圖11和圖13的例子中，3片皺紋紙中位於重疊方向的最下端的皺紋紙(端部片材)由具有非壓花部160的皺紋紙120構成。 Further, in the examples of FIGS. 7, 9, and 13, the crepe paper (end sheet) located at the uppermost end in the overlapping direction among the three sheets of crepe paper is composed of the crepe paper 10 having the non-embossed portion 50. Further, in the examples of FIGS. 11 and 13, the crepe paper (end sheet) located at the lowermost end in the overlapping direction among the three sheets of crepe paper is composed of the crepe paper 120 having the non-embossed portion 160.

即，具有可發揮設計性的非壓花部50或非壓花部160的皺紋紙10或皺紋紙120配置於廚房紙100的正面或背面。因此，即使在重疊3片皺紋紙而增厚廚房紙100的厚度的情況下，廚房紙100的從外部來看的辨識性也良好。 That is, the crepe paper 10 or the crepe paper 120 having the non-embossed portion 50 or the non-embossed portion 160 that can exhibit the design property is disposed on the front surface or the back surface of the kitchen paper 100. Therefore, even when the thickness of the kitchen paper 100 is thickened by stacking three sheets of crepe paper, the visibility of the kitchen paper 100 from the outside is good.

此外，在圖7和圖9的例子中，3片皺紋紙中位於重疊方向的最下端的皺紋紙(端部片材)由不具有非壓花部的皺紋紙110構成。此外，在圖11的例子中，3片皺紋紙中位於重疊方向的最上端的皺紋紙(端部片材)由不具有非壓花部的皺紋紙10構成。 Further, in the examples of FIGS. 7 and 9, the crepe paper (end sheet) located at the lowermost end in the overlapping direction among the three sheets of crepe paper is composed of the crepe paper 110 having no non-embossed portion. Further, in the example of Fig. 11, the crepe paper (end sheet) which is located at the uppermost end in the overlapping direction among the three sheets of crepe paper is composed of the crepe paper 10 which does not have the non-embossed portion.

即，由於在直接受到向厚度方向的負荷的廚房紙100的正面或背面配置有相對於厚度方向的負荷的強度高的皺紋紙(僅由壓花部形成的皺紋紙)，因此即使在重疊3片皺紋紙而增厚廚房紙100的厚度的情況下，也能夠提高廚房紙100的厚度方向的強度，因此能夠維持負荷時的吸油性能。 In other words, the crepe paper (the crepe paper formed only by the embossed portion) having a high load with respect to the load in the thickness direction is disposed on the front surface or the back surface of the kitchen paper 100 directly subjected to the load in the thickness direction, and therefore even overlaps 3 When the thickness of the kitchen paper 100 is increased by the crepe paper, the strength of the kitchen paper 100 in the thickness direction can be increased, so that the oil absorbing performance at the time of load can be maintained.

A plastic sheet (approximately 12 cm × 12 cm, a thickness of 0.2 mm, a weight of 2.7 g, a material polypropylene) shown in Fig. 15 , a test piece, and a pressed iron (approximately diameter) were measured using an electronic balance (HR300 manufactured by A&D Co., Ltd.). 82mm, thickness 10mm, weight 59g, material acrylic resin ( )), each weight of the base paper (the paper is cut into five sheets of paper having a size of about 12 cm × 12 cm). After the measurement, a test piece was placed on a plastic sheet, and a weight was placed on the center of the test piece. In addition, the weight is provided with a hole penetrating in the thickness direction. The diameter of the hole is approximately 12 mm.

然後，使用移液管(Thermo scientific公司製，FinnpipetteF2，0.5~5ml)從壓鐵的孔滴加2.3ml(約2.0g)的油(常溫的沙拉油)(日清奧利友集團株式會社製的日清沙拉油)。此時，滴加位置(壓花部)如圖15所示那樣預先固定於試驗片的中心位置。 Then, using a pipette (Finnpipette F2, 0.5 to 5 ml, manufactured by Thermo Scientific Co., Ltd.), 2.3 ml (about 2.0 g) of oil (normal temperature salad oil) was added dropwise from the pores of the iron (manufactured by Nisshin Olympus Corporation). Nisshin Salad Oil). At this time, the dropping position (embossed portion) is fixed to the center position of the test piece in advance as shown in FIG. 15 .

在比較例1中，使用圖16和圖17所示的廚房紙100。比較例1中，採用頂對頂形式，非壓花部50的面積率設為37.4%，將非壓花部50的圖案設為格子形狀，除此以外，與實施例1同樣地進行。在比較例1中，非壓花部50與非壓花部60相對而形成，且形成有具有交叉部CP的非壓花空間LN。將比較例1的條件和結果示於表1。 In Comparative Example 1, the kitchen paper 100 shown in Figs. 16 and 17 was used. In the first comparative example, the same as in the first embodiment, the area ratio of the non-embossed portion 50 was set to 37.4%, and the pattern of the non-embossed portion 50 was a lattice shape. In Comparative Example 1, the non-embossed portion 50 is formed to face the non-embossed portion 60, and a non-embossed space LN having the intersection portion CP is formed. The conditions and results of Comparative Example 1 are shown in Table 1.

〔比較例2〕 [Comparative Example 2]

比較例2中，使用圖18和圖19所示的廚房紙100。比較例2中，對於原紙，使用了克重21.2g/m2的原紙，除此以外，與實施例1同樣地進行。對於壓花條件，將非壓花部50的圖案設為蜂窩形狀，將壓花凸部的個數設為2172個/144cm2，將皺紋紙10的壓花凸部EC與皺紋紙20的非壓花凸部NE的黏合面積率設為8.1%，將全部壓花凸部的容積設為13275mm2，將非壓花部50、60的面積率設為19.1%，除此以外，與實施例1同樣地進行。在比較例2中，非壓花部50與非壓花部60相對而形成，且形成有具有交叉部CP的非壓花空間LN。將比較例2的條件和結果示於表1。 In Comparative Example 2, the kitchen paper 100 shown in Figs. 18 and 19 was used. In Comparative Example 2, the same procedure as in Example 1 was carried out except that a base paper having a basis weight of 21.2 g/m 2 was used for the base paper. For the embossing conditions, the pattern of the non-embossed portion 50 is set to a honeycomb shape, and the number of the embossed convex portions is set to 2172 / 144 cm 2 , and the embossed convex portion EC of the crepe paper 10 and the crepe paper 20 are not The adhesion area ratio of the embossing convex portion NE was 8.1%, the volume of all the embossing convex portions was 13275 mm 2 , and the area ratio of the non-embossed portions 50 and 60 was 19.1%. 1 is carried out in the same manner. In Comparative Example 2, the non-embossed portion 50 is formed to face the non-embossed portion 60, and a non-embossed space LN having the intersection portion CP is formed. The conditions and results of Comparative Example 2 are shown in Table 1.

根據表1，在實施例1~7中，相對於滴加油量的試驗片吸油率以及最終保持率均與比較例1、比較例2相比變高。此外，相對於滴加油量的試驗片的回液率與比較例1、比較例2相比變低。即，顯示出實施例1和實施例2的油保持性能高。特別是與具備相同的嵌套形式的層疊結構(2層片)的比較例2相比，實施例1~實施例3顯示出高的油保持性能。 According to Table 1, in each of Examples 1 to 7, the oil absorption rate and the final retention ratio of the test piece with respect to the amount of dripping oil were higher than those of Comparative Example 1 and Comparative Example 2. Further, the liquid-repellent rate of the test piece with respect to the amount of dripping was lower than that of Comparative Example 1 and Comparative Example 2. That is, it was revealed that the oil retaining performance of Example 1 and Example 2 was high. In particular, Examples 1 to 3 exhibited high oil retaining performance as compared with Comparative Example 2 having the same nested structure (two-layer sheet).

此外，實施例1~7中，相對於滴加油量的透印率、透印總率均與比 較例1、比較例2相比變低。該結果表示在實施例1~實施例7中抑制了油的透印(難以滲出)。特別是與具備相同的嵌套形式的層疊結構(2層片)的比較例2相比，實施例1~實施例3也顯示出油難以透印。 Further, in Examples 1 to 7, the offset ratio and the total print-through ratio with respect to the amount of dripping were lower than those of Comparative Example 1 and Comparative Example 2. This result indicates that the offset of the oil was inhibited (difficult to bleed out) in Examples 1 to 7. In particular, in Comparative Examples 2 having the same nested structure (two-layer sheet), Examples 1 to 3 also showed that the oil was difficult to be printed.

此外，在實施例1與實施例3、或實施例5與實施例6中，形成有非壓花部的皺紋紙的位置成為上下相反的位置，但相對於相同嵌套形式的比較例2，均維持了高的油保持性能。從該結果可知，使用物件所接觸的面不管是廚房紙100的正面和背面，均能夠發揮高的油保持性能。 Further, in the first embodiment, the third embodiment, or the fifth and sixth embodiments, the position of the crepe paper in which the non-embossed portion is formed is the upper and lower positions, but the comparative example 2 of the same nested form is used. Both maintain high oil retention properties. From this result, it is understood that the surface to be contacted by the article can exhibit high oil retaining performance regardless of the front and back surfaces of the kitchen paper 100.

另外，即使比較設計性，也由於在實施例1~7中在廚房紙100整體配置有非壓花部，因此相對於存在非壓花空間的比較例1和比較例2，設計性也並不差。 Further, even if the design is not preferable, since the non-embossed portions are disposed on the entire kitchen paper 100 in the first to seventh embodiments, the design is not the same as in the comparative example 1 and the comparative example 2 in which the non-embossed space is present. difference.

以上，對本發明的優選實施方式進行了詳述，但本發明並不限定於該特定的實施方式，可以在專利請求保護的範圍所記載的發明範圍內進行各種變形、變更。 The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the specific embodiments, and various modifications and changes can be made within the scope of the invention as described in the appended claims.
