Description

The present invention relates to a film packaging type sanitary tissue paper package in which a bundle of sanitary tissue paper such as tissue paper is wrapped with a film.

As for the packaging of sanitary tissue paper such as tissue paper, a paper box type storage body called a box tissue that stores a bundle of sanitary tissue paper in a paper storage box such as a white ball called a carton is well known. Most of the paper box type sanitary tissue paper packages are stored as a pop-up type bundle of about 120 to 250 sets of two to four sheets of sanitary tissue paper.

On the other hand, with the aim of reducing packaging materials and improving transportation costs and portability by making them compact, pop-up bundles of the same number as the above-mentioned paper box type storage body are wrapped with a flexible resin film. There is a film wrapping type sanitary tissue paper wrapping body.

As the film-wrapping type sanitary tissue paper wrapping body, a pillow wrapping type and an overlap wrapping type are well known. In the pillow packaging form, a bundle to be packaged is wrapped with a long film so as to be wrapped in the width direction, the edges overlapping in the winding direction are adhered to each other, and further beyond the object to be packaged in the film length direction. It is a packaging form in which the extended portion is bonded and sealed in a gusset style.

Overlap wrapping is a wrapping form also called caramel wrapping or combined wrapping, in which a bundle to be packaged is wrapped with a film so as to be wrapped in a tubular shape, and the overlapping portions in the wrapping direction are adhered to each other. The portion of the film extending beyond the bundle to be packaged is folded from the two opposite edges toward the packaged object, and at least the tip edges of the triangular or square pieces formed at that time are bonded to each other. It is a packaging mode in which the film is sealed. Compared to the pillow wrapping, this overlap wrapping has a shape closer to the straight hexahedron shape, and the sealing part formed by adhering triangular or quadrangular pieces has high rigidity, so that sanitary tissue paper can be used after opening. Many of them have excellent shape retention of the packaging bag even if the height of the bundle is lowered by using it.

On the other hand, the outlet of the film-wrapped type sanitary tissue paper package is often a paper box type, in addition to a slit-shaped outlet formed by arranging one perforation in a straight line on the upper surface and dehiscence it. It is common to form a squared rectangular, rectangular or elliptical annular perforation on the upper surface to be seen and to make a squared rectangular, rectangular or oval opening formed by cutting off the part. It was.

JP-A-2002-308352 JP-A-2010-195443 JP-A-2018-52559 Japanese Unexamined Patent Publication No. 2004-224362 Japanese Unexamined Patent Publication No. 2016-188092

However, if one perforation is arranged in a straight line on the upper surface portion, it is easy to tear beyond both ends of the perforation at the time of opening.
In addition, since the shape of the packaging bag of the above-mentioned overlap packaging is not easily deformed, a simple slit-shaped outlet has a large resistance when taking out sanitary tissue paper, and in particular, the number of sets forming the bundle is reduced and its own weight. When the weight becomes lighter, the whole package tends to be lifted. In the case of a simple rectangular, rectangular or elliptical opening, the sheet tends to fall into the package through the opening, especially when the number of sets constituting the bundle is small.

Therefore, a main object of the present invention is to provide a sanitary thin paper package of overlap packaging, which is excellent in the ease of taking out the sanitary thin paper and the prevention of depression.

It is a perspective view for demonstrating the bundle of the sanitary tissue paper package which concerns on this invention. It is a figure for demonstrating the packaging form of the sanitary tissue paper package which concerns on this invention. It is a cross-sectional view of AA of FIG. 1 or 3, and is a figure for demonstrating the packaging form. It is a perspective view at the time of use of the sanitary tissue paper package which concerns on this invention. It is a top view which shows the outlet formation part of the sanitary tissue paper package which concerns on this invention.

Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 6.
The sanitary tissue paper package 1 of the present embodiment is obtained by wrapping a bundle 3 of sanitary tissue paper 2 with a film 4, and for taking out the sanitary tissue paper 2 contained in the top surface portion 1A of the film 4 one by one. An outlet forming portion 50 for forming the outlet 60 is provided.

The sanitary tissue paper package 1 is a so-called pop-up type, and when one or a set of sanitary tissue paper 2 is taken out from the outlet 60 formed by dehiscence of the outlet forming portion 50 or the like, the sanitary tissue paper 2 is taken out. A part of the sanitary tissue paper 2 to be taken out next is exposed and is in a state of being picked. In addition, in FIG. 1 and FIG. 3, the part represented by dehiscence of the outlet forming portion 50 to be the outlet 60 is indicated by the same reference numeral.

The sanitary tissue paper 2 according to the present embodiment is tissue paper, paper towel, toilet paper, or the like. Among them, the present invention is particularly effective in the case of a tissue paper having a ply structure in which two to four base papers having a dry crepe are laminated and assembled. In the ply structure, both ends of the laminated continuous sheet can be joined by contact embossing, the four sides around the sanitary tissue paper sheet, or the entire surface of the sheet can be joined by embossing means. Further, the sanitary tissue paper 2 according to the present invention is a dried dry type, not a so-called wet type impregnated with a chemical solution. Therefore, the bundle 3 contains air between the layers. Among the dry type sanitary tissue paper 2, especially the tissue paper, there is a moisturizing tissue to which a moisturizing agent or the like is applied. However, in the sanitary tissue paper package 1 according to the present invention, the bundle 3 is wrapped with the film 4. Therefore, the inclusions are less likely to dry than the paper box type, and the paper in the paper box is not distorted due to the moisture absorption peculiar to the moisturizing tissue, which is particularly effective in the moisturizing tissue.

In the suitable sanitary tissue paper 2 according to the present invention, the raw material pulp is a mixture of NBKP and LBKP. Waste paper pulp may be blended, but it is preferable that it is composed of only NBKP and LBKP in terms of texture and the like. The blending ratio is preferably NBKP: LBKP = 20: 80 to 80:20, and particularly preferably NBKP: LBKP = 30: 70 to 60:40.

It is desirable that the sanitary tissue paper has a basis weight of 10 to 25 g / m ² per ply (per base paper constituting a set). In particular, it is preferably 10 to 18 g / m ² . The basis weight here refers to the measurement method of JIS P 8124 (1998). The thickness of the sanitary tissue paper is not necessarily limited, but is 90 to 170 μm, more preferably 90 to 150 μm in the 2-ply state. It is 180 to 280 μm in a 3-ply state, more preferably 180 to 250 μm. It is 200 to 320 μm in the 4-ply state, and more preferably 200 to 280 μm. The paper thickness here is determined by adjusting the humidity of the test piece sufficiently under the conditions of JIS P 8111 (1998), and then using the dial thickness gauge (thickness measuring instrument) "PEACOCK G type" (manufactured by Ozaki Seisakusho) under the same conditions. It refers to the value measured in a set using.

As shown in FIG. 2, the bundle 3 of the sanitary tissue paper 2 according to the present invention is formed by folding a square sanitary tissue paper 2 having a length of 180 to 210 mm and a width of 130 to 160 mm in half and arranging them vertically on the folded inner side 2A. A plurality of sanitary tissue papers are folded and laminated so that the folded piece 2B of the other sanitary tissue papers is located. Therefore, the bundle 3 has a pair of longitudinal side surfaces 3A in which the folded edges 2C of each sanitary tissue paper are lined up, and a pair of short side surfaces 3B in which the folded edges 2C are not lined up, and further formed on the short side surface 3A and the longitudinal side surface 3B. It has a rectangular parallelepiped shape with a pair of connecting planes (top and bottom) 3C. The top surface portion 1A according to the present invention is a portion of the film facing the plane 3C. The size of the bundle 3 is not necessarily limited, but is generally about 153 mm (M size) in width or 137 mm (S size) in width × 96 mm in depth × 43 mm in height. Then, in this bundle 3, when one folded piece located at the highest position is pulled upward, another adjacent folded piece immediately below the folded piece is dragged upward and lifted, so that a so-called pop-up is made. .. Such a bundle 3 can be manufactured by a known multi-stand type or rotary type interfolder.

The number of sets of sanitary tissue paper 2 constituting the bundle 3 is not limited, but generally, a tissue paper storage body containing tissue paper has 2 plies (2 sheets stacked) and 3 plies (2 plies). The number of sets is 80 to 240 with 3 plies (3 layers) or 4 plies (4 layers) as one set, and the sanitary tissue paper packaging of the present embodiment is also preferably 80 to 240 sets.

The packaging form of the bundle 3 by the film 4 of the sanitary tissue paper packaging body 1 according to the present invention is overlap packaging. The overlap packaging is a packaging form also called caramel packaging. In particular, as shown in FIGS. 3 and 4, the bundle 3 to be packaged is wrapped with a film 4 in a tubular shape, and the winding direction thereof. In the overlapping portion 4A (FIG. 4), the films of the upper and lower layers are bonded by a fusion treatment or an adhesive (the bonded portion is indicated by reference numeral 4S in FIG. 4), and further extends beyond the bundle 3 which is the object to be packaged. The formed portion 4B (FIG. 3) is folded into the packaged object side from two edges facing each other on the side surfaces or the top surface and the bottom surface, and at least each tip edge portion of the triangular or trapezoidal piece formed at that time is folded. Is a packaging mode in which the cylinder opening 4X is sealed by bonding with a fusion treatment or an adhesive.

The sanitary tissue paper package 1 according to the present invention is, in particular, an overlap wrapping, and as shown in FIG. 3, a cylinder opening sealing portion 4C (FIGS. 1 and 5) formed by sealing the cylinder opening 4X is provided. , A packaging form in which the bundle 3 faces the lateral side surface 3B. Since the opening sealing portion 4C of the overlap packaging has a planar shape formed by stacking and adhering a plurality of layers of films, the overall outer shell shape has a straight hexahedron shape close to that of a paper box. Further, since the opening sealing portion 4C is adhered after the multiple layers of films 4 are laminated, the rigidity of the portion tends to be high. The sanitary tissue paper packaging 1 according to the present invention, represented by a film packaging tissue, may be piled up and sold in stores, and the shape of the product is close to a straight hexahedron and is excellent in shape retention without being crushed. Therefore, the overlap packaging according to the present invention is desirable from the viewpoint of the rigidity and the shape.

Further, in the sanitary tissue paper package 1 according to the present invention, the difference between the outer shell size (width x depth x height) of the film 4 and the bundle size (width x depth x height) is not necessarily limited. However, in this kind of product, it is generally -2 mm to +5 mm with respect to the bundle size, and the same can be applied to the sanitary tissue paper package 1 according to the present invention.

In the sanitary tissue paper package 1 according to the present invention, the overlap packaging is performed, and the outlet forming portion 50 for forming the outlet 60 is in the width direction in which the folded edge 2C of the sanitary tissue paper 2 extends. A pair of first easy dehiscence lines 5A, 5A extending along 3W and separated in a depth direction 3D orthogonal to the width direction, and a pair of first easy opening lines extending along the depth direction 3D. The range is surrounded by a pair of second easy dehiscence lines 5B and 5B connecting the ends of the dehiscence lines 5A and 5A. Here, the easy dehiscence lines 5A and 5B are lines made easy to dehiscence by the lines, such as perforations and slit lines provided with uncut portions at appropriate intervals. In addition, the line may be formed by reducing the thickness of the film.

Further, in the outlet forming portion 50 according to the present invention, characteristically, the pair of first easy dehiscence lines 5A and 5A are connected to the second dehiscence lines 5B and 5B from P1 and P1 to the bundle 3. The end squeezed portion 51, which gradually approaches each other toward the central portion in the width direction and narrows between them, and the pair of first I Ching opening lines 5A and 5A form the central portion in the width direction of the bundle 3 from the end stenosis portion 51 side. The widening portion 52, which gradually separates from each other and widens between them toward the side, and the pair of first I Ching opening lines 5A, 5A are at least thirst toward the central portion in the width direction of the bundle 3 from the widening portion 52. It has a shape with a wide portion 53 that gradually separates and bulges outward in the depth direction until the length between them becomes longer than the length of the I Ching opening line 5B, and in particular, the end. Between the narrowed portion 51 and the widened portion 52, the JW between the first easy dehiscence lines is 10% or less, preferably 1.6 to 8.3% of the length L1 in the depth direction of the bundle 3. In the wide portion 53 , the length SW between the first easy cleavage lines 5A and 5A is 60% or less, preferably 45 to 57% of the length L1 in the depth direction of the bundle 3 .

The sanitary tissue paper package 1 according to the present invention has a shape in which the outlet forming portion 50 has such an acute-angled portion 51, a widening portion 52, and a wide portion 53, and therefore is within the range of the outlet forming portion 50. First, at the position of the end stenosis portion 52, a sharp corner portion P (FIGS. 5 and 6) is located between the first easy cleavage line 5A and the second easy cleavage line 5B. Is formed. That is, since the end constriction portion 51 is arranged so that the pair of first fissure lines 5A approach each other from the end of the second easy fissure line 5B along the depth direction, the end constriction portion 51 is cut off. At the portion position, acute-angled corner portions P and P having the end position of the second fissure line 5B outward in the depth direction as the apex are formed.

Further, in the sanitary tissue paper package 1 according to the present invention, since the outlet forming portion 50 has such an end narrowing portion 51, a widening portion 52 and a wide portion 53, the outlet forming portion 50 of the outlet forming portion 50. When the inside of the range is cut off, free edge pieces 61 and 61 including the edge in the range from the end narrowed portion 51 to the wide portion 53 are formed. That is, the pair of first easy cleavage lines 5A and 5A according to the present invention first approach the central portion in the width direction of the bundle 3 at the end constriction portion 51, further separate at the widening portion 52, and further widen. Since 53 extends outward in the depth direction from the end of the second easy opening line 5B, the edge E1 in the range from the end stenosis 51 to the wide portion 53, the corner P, and at least the second easy fissure in the wide portion. The range connecting the end of the open line 5B to the outer position P2 in the depth direction of the bundle 3 is the free edge piece 61 formed of the flexible film 4.

The sanitary tissue paper package 1 according to the present invention is excellent in pullability and drop prevention because the outlet 60 related to the outlet forming portion 50 is formed. The ease of removal includes, in addition to being able to smoothly pull out the sanitary tissue paper, that a part of the next sheet or set exposed after pulling out one sheet or one set is easy to stand on its own and easy to pick up.
In the sanitary tissue paper package 1 according to the present invention, since the opening is wide at the position corresponding to the wide portion 53, there is little resistance at the time of pulling out, so that it is easy to pull out smoothly. Also, the first one is easy to pick. In particular, the length SW between the first easy dehiscence lines 5A and 5A in the wide portion 53 is 60% or less in the depth direction of the bundle, an excessively wide opening is not formed, and the drop prevention property is other. It is secured in combination with the composition of. On the other hand, in particular, as shown in FIG. 5, the edge 20E at the root portion of the next one or set of exposed portions 20 after taking out one or one set has entered the corner portion P. Will be supported. At that time, the edge piece 61 located on the corner side opposite to the corner portion P into which the edge 20E of the sanitary thin paper 2 is fitted comes to lean against the exposed portion 20 of the sanitary thin paper 2, and the edge 20E of the sanitary thin paper 2 is used. It pushes toward the corner P side and the fit is maintained. As a result, the independence and depression prevention of a part 20 of the following sanitary tissue paper will be excellent.

Further, since the bundle 3 has a pop-up type structure like the sanitary tissue paper package 1 according to the present invention, when pulling out one sheet or a set, the edge 20E of a part 20 of the sanitary tissue paper 3 pulled out thereafter and The surface moves toward the outlet while moving in the depth direction 3D, and when exposed from the outlet 60, is guided by the edge of the outlet 60. In the sanitary tissue paper package 1 according to the present invention, a part 20 of the sanitary tissue paper 2 is pulled out because the outlet 60 widens from the position between the end constriction portion 51 and the widening portion 52 toward the end constriction portion position. At this time, the edge 20E of the sanitary thin paper 2 is easily guided to the corner P. Further, in particular, the width between the end narrowed portion 51 and the widened portion 52 is narrowed to 10% or less of the length of the bundle 3 in the depth direction 3D, so that the surface of the sanitary tissue paper 2 is reliably supported by the edge. It is done and the depression prevention property is improved. It should be noted that the surface of the sanitary tissue paper 2 is more supported by providing a connecting portion 54 in which the distance between the first easy tearing lines 5A and 5A is 10% or less and the distance between the pair of first easy tearing lines is constant. It becomes easier and the prevention of depression is improved.

Here, it is desirable that the pair of first easy dehiscence lines 5A and 5A in the end constriction portion 51 and the widening portion 52 are curved lines. Since the edge E of the outlet 60 has a smooth curve, the sanitary tissue paper 2 is smoothly guided by the edge, and the pullability becomes more excellent.
The overall outline of the wide portion 53 is not particularly limited, but a circular shape, an elliptical shape, or a squared quadrangle having curved edges as shown in the illustrated example is desirable. It is hard to get caught in the edge when pulling out and it becomes easy to pull out smoothly.

The length PW of the bundle 3 of the first easy tearing lines 5A and 5A in the sanitary thin paper package 1 according to the present invention in the width direction 3W is shorter than the width direction length L2 of the bundle 3, especially 87 to 97%. It is desirable to have it. If it exceeds 97%, it becomes difficult for the edge 20E of the sanitary thin paper 2 to enter the corner P.

Further, it is desirable that the length EW of the second easily split opening line 5B in the sanitary tissue paper package 1 according to the present invention is 3 to 16% of the length L1 of the bundle 3 in the depth direction 3D. Within this range, the edge 20E can easily enter the corner portion P.

The width Bh of the edge piece 61 in the sanitary tissue paper package 1 according to the present invention, that is, the line Bb (line) connecting the corner portion P1 (one of the corner portions P) and the corresponding edge point P2 of the wide portion 53. The length Bh from (Bb passes through the corner portion P1 at the tangent line of the outer edge of the wide portion 53) to the opening edge E is preferably 8 to 24 mm. The position P2 on the edge side of the wide portion 53 on the line Bb connecting the corner portion P and the edge of the wide portion 53 is a position where the width Bh is the longest. If the width is within the above range of Bh, the size of general sanitary tissue paper can be sufficiently pressed and held.

On the other hand, the first easy tear line 5A and the second easy tear line 5B in the sanitary thin paper package 1 according to the present invention shall be composed of perforations or slits having uncut portions at appropriate positions as described above. However, more preferably, the first easy dehiscence line 5A is used as a slit that communicates inside and outside in the end narrowing portion 51 and the widening portion 52, and the tie 0.5 mm to 3 in the connecting portion 54 and the wide portion 53. Perforations of 0.0 mm and cuts of 1.0 mm to 7.00 mm are desirable. In the connecting portion 54 and the wide portion 53, the tie is 1.5 mm to 2.5 mm and the cut is 2.0 mm to 5.0 mm. It is hard to tear during transportation and loading, and it is easy to break with your fingers. Further, it is desirable that the second easy dehiscence line 5B is a perforation in which the position to be the corner portion P is cut, or a slit in which an uncut portion is provided particularly in the central portion in the depth direction 3D. When the slits and perforations are formed in this way, as shown in FIG. 6, the end portion while pressing the position X1 between the end constricted portion 51 on the top surface portion and the widthwise edge 1E of the package 1 with a finger. When the stenosis portion 51 is pulled away from the edge 1E, the end stenosis portion 51 becomes a peeled knob portion, and when the stenosis portion 51 is pulled toward the opposite end stenosis portion 51, the first easy tear opening line 5A The outlet forming portion 50 surrounded by the second easy opening line 5B is smoothly peeled off, and the opening 60 can be easily formed, so that the opening property becomes excellent.

Here, examples of the specific flexible resin film material constituting the film 4 according to the present invention include a polyethylene film, a polypropylene film, a polyester film, a polyethylene terephthalate film, a nylon film, a vinylidene chloride film, and an ethylene vinyl alcohol. Examples thereof include a monolayer film of a copolymer, an appropriately laminated laminated film containing those films, and a gas barrier film obtained by subjecting these films to a surface treatment such as aluminum vapor deposition. However, polypropylene film and polyethylene film are suitable from the viewpoint of cost. In particular, a non-stretched polypropylene film (CPP) having excellent heat-sealing properties is desirable.

The thickness of the film 4 may be appropriately selected in consideration of flexibility, cost, gas permeability, and heat fusion property at the time of packaging, but is preferably measured in accordance with JIS P 8118 (1998). It is desirable that the thickness is 20 to 60 μm and the softness measured based on the handle ometer method according to the JIS L 1096 (2010) E method is 5.0 to 50.0 cN. With such a thickness and softness, the film is not easily torn, and it is easy to make the film excellent in pop-up property.

(Test example)
Next, the shape of the outlet forming portion in the sanitary tissue paper package according to the present invention was tested for openability, pullability and depression. Examples are those according to the present invention, and comparative examples are those outside the present invention. Comparative Example 5 has an opening forming portion formed by one of the perforations along the bundle width direction, and the outlet is a linear slit. The tie-cut ratio is 2 mm for tie and 3 mm for cut.
The packaging form is all overlapping packaging, and the sealing portion is by heat fusion. The outer shell size of the product and the size of the bundle were prepared in almost the same manner except for manufacturing errors, and the bundle was a commercially available S size and an M size. The M size is a bundle of non-moisturizing tissue papers containing no moisturizing agent, and the S size is a bundle of moisturizing type tissue papers containing 14% by mass of a moisturizing agent.
