Description

Sanitary foil paper packaging

The present invention relates to a film packaging type sanitary foil packaging body in which a bundle of sanitary foil papers such as tissue paper is packaged with a film.

As for the sanitary foil packaging body such as tissue paper, a paper box-type storage body, also called a box tissue, in which a bundle of sanitary foil papers are stored in a paper storage box such as white cardboard called a carton, is well known. Most of this paper box-type sanitary foil packaging body is housed in a pop-up bundle of about 120 sets to 250 sets of 2 to 4 sheets of sanitary foil paper as one set.

On the other hand, for the purpose of reducing packaging materials and improving transportation costs and portability due to compactness, film packaging in which pop-up bundles of the same number of sets as the above paper box-type storage bodies are packaged with a flexible resin film. There are types of sanitary foil paper packaging.

As a sanitary foil packaging body of this film packaging type, it is well known that it is a pillow packaging type and an overlap packaging type. In the form of pillow packaging, the bundles to be packaged are wrapped with a long film in the width direction, and overlapping borders are bonded in the winding direction, and the part extending in the long direction of the film beyond the package is gusseted. It is a form of packaging that is adhered and sealed.

Overlap packaging is a packaging form, also called caramel packaging or combined packaging, and wraps the bundle to be packaged in a tubular shape with a film, attaches the overlapping part in the winding direction, and furthermore, the film goes beyond the bundle, It is a packaging mode in which the extended portions are folded from two opposing edges toward the object to be packaged, and at least each of the leading edge portions of the triangular or square pieces formed at that time are bonded to each other and sealed. Compared to the pillow packaging, the overlap packaging has a shape closer to the rectangular parallelepiped shape, and the stiffness of the bag portion formed by bonding a triangle or square piece is high, and the height of the bundle is increased by using a sanitary foil paper after opening. Even if it is lowered, many packaging bags have excellent shape retention.

On the other hand, the outlet of the film packaging type sanitary foil packaging body is a slit shape formed by arranging one dotted line in a straight line on the upper surface part and opening it, and a chamfered rectangle on the upper surface part often seen in the paper box type. , In general, a rectangular or elliptical annular dotted line is formed, and a chamfered rectangular, rectangular, or elliptical opening is formed by removing the corresponding portion.

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

However, when one dotted line is arranged in a straight line on the upper surface portion, it is liable to break over both ends of the dotted line at the time of opening.

In addition, since the above-described overlap packaging is difficult to collapse in the shape of the packaging bag, a simple slit-type outlet has a high resistance when taking out the sanitary foil paper, and in particular, the number of sets constituting the bundle is small, and its own weight has been reduced. It is easy to be lifted up by each package at the time. In the case of a simple chamfered rectangular, rectangular or elliptical opening, particularly when the number of sets constituting the bundle is reduced, the sheet is likely to fall from the opening into the package body.

Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 6.

The sanitary foil paper packaging body 1 of the present embodiment is a product in which the bundle 3 of the sanitary foil paper 2 is packaged with a film 4, and is enclosed in the ceiling surface portion 1A of the film 4 There is provided an outlet forming portion 50 for forming an outlet 60 for taking out the sanitary foil (2) one by one.

This sanitary foil packaging body 1 is a so-called pop-up type, and when one sheet or a set of sanitary foil paper 2 is taken out from the outlet 60 formed by opening the outlet forming portion 50 or the like, Then, a part of the sanitary foil (2) to be taken out is exposed so that it can be caught. In addition, in Figs. 1 and 3, a portion indicated by opening the outlet forming portion 50 to form the outlet 60 is indicated by the same reference numeral.

The sanitary foil 2 according to the present embodiment is a tissue paper, a paper towel, a 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 dry crepe are stacked to form a set. In the ply structure, both ends of the laminated continuous sheet can be joined by contact embossing, or the peripheral four sides of the sanitary foil sheet or the entire surface of the sheet can be joined by a frame pressing means. In addition, the sanitary foil 2 according to the present invention is a dried dry type, and is not of a so-called wet type impregnated with a chemical solution. Therefore, the bundle 3 contains air between the layers. In addition, among dry-type sanitary foils 2, especially in tissue paper, there is a moisturizing tissue to which a moisturizing agent or the like is added, but in the sanitary foil packaging 1 according to the present invention, the bundle 3 is a film. Since it is packaged in (4), the inclusions are more difficult to dry than those of the paper box type, and the paper box is not deformed due to moisture absorption peculiar to the moisturizing tissue, which is particularly effective in the moisturizing tissue.

In a suitable sanitary foil (2) according to the present invention, the raw material pulp is a mixture of NBKP and LBKP. Although used paper pulp may be blended, it is preferable to consist of only NBKP and LBKP from the viewpoint of touch and the like. As a compounding ratio, NBKP:LBKP=20:80-80:20 is good, In particular, NBKP:LBKP=30:70-60:40 is good.

The sanitary foil paper preferably has a basis weight of 10 to 25 g/m 2 per ply (per sheet of raw paper constituting one 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 paper thickness of the sanitary foil is not necessarily limited, but is 90 to 170 µm in a two-ply state, and more preferably 90 to 150 µm. In a three-ply state, it is 180 to 280 µm, more preferably 180 to 250 µm. It is 200 to 320 µm in a four-ply state, more preferably 200 to 280 µm. The paper thickness here is in the state of one set using a dial health gauge (thickness gauge) ``PEACOCK G type'' (Ozaki Manufacturing Co., Ltd.) under the same conditions after sufficiently humidifying the test piece under the conditions of JIS P 8111 (1998). It refers to the measured value.

As for the bundle 3 of the sanitary foil 2 according to the present invention, as shown in FIG. 2, in particular, two rectangular sanitary foils 2 of 180 to 210 mm in length x 130 to 160 mm in width are folded. , In the folded inner side 2A, other sanitary foil papers positioned up and down are arranged so that the folded piece 2B is positioned so that a plurality of sanitary foil papers are folded and stacked small. Accordingly, the bundle 3 has a pair of rectangular side surfaces 3A on which the folded edges 2C of each sanitary tissue are arranged, and a pair of short sides not arranged by the folded edges 2C ( 3B), and a rectangular parallelepiped shape having a pair of flat surfaces (ceiling surface and bottom surface) 3C connected to the short side 3A and the long side 3B. In addition, the ceiling surface part 1A which concerns on this invention is a part which faces this plane 3C of a film. The size of the bundle 3 is not necessarily limited, but is generally about 153 mm wide (M size) or 137 mm wide (S size) x 96 mm deep x 43 mm high. And, when this bundle (3) is pulled up, the folded side of one folded sheet located at the top, the other folded side of the next adjacent sheet is pulled upward and lifted up, so that a so-called pop-up is generated. do. Such a bundle 3 can be manufactured by a multi-stand type, a rotary type existing interfolder.

In addition, the number of sets of the sanitary foil (2) constituting the bundle (3) is not limited, but in general, 2 plies (2 sheets stacked) and 3 plies (3 sheets) for a tissue paper container containing tissue paper. Each overlap) or 4 plies (4 sheets overlap) as one set, 80 to 240 sets, and 80 to 240 sets similarly to the sanitary foil paper packaging body of the present embodiment is preferable.

The packaging form of the bundle 3 by the film 4 of the sanitary foil packaging body 1 which concerns on this invention is overlap packaging. The overlap packaging is a packaging form also referred to as caramel packaging. In particular, as shown in Figs. 3 and 4, the bundle 3 to be packaged is wrapped in a cylindrical shape with a film 4, and in the winding direction In the overlapping portion 4A (Fig. 4), the upper and lower layers of the film are bonded by fusion treatment or an adhesive (in Fig. 4, the bonding portion is indicated by reference numeral 4S), and the portion 4B that extends beyond the bundle 3 which is a package object ( Fig. 3) is folded from the two edges facing each other or the ceiling and the bottom to the side of the package, and at least each of the ends of the triangular or trapezoid formed at that time is bonded to each other with a fusion treatment or an adhesive. Thus, it is a packaging aspect formed by sealing the cylinder opening 4X.

The sanitary foil packaging body 1 according to the present invention is, in particular, an overlap packaging, as shown in Fig. 3, a cylinder opening sealing portion 4C formed by sealing the cylinder opening 4X (Fig. 1, Fig. 5). It is a packaging type that faces the short side (3B) of the bundle (3). Since the opening-sealing portion 4C of the overlap packaging has a planar shape formed by bonding a plurality of layers of films overlaid thereon, the entire outer shape becomes a rectangular parallelepiped shape close to that of a paper box. Further, since the opening-sealing portion 4C is adhered after the plurality of layers of the film 4 are stacked, the rigidity of the portion tends to be increased. The sanitary foil packaging body 1 according to the present invention, represented by a film wrapping tissue, is sometimes sold in bulk at the storefront, and the shape of the product is close to a rectangular parallelepiped, and it is preferable that the shape of the product is not collapsed and has excellent shape retention. Therefore, the overlap packaging according to the present invention is preferable from the viewpoint of the related rigidity and shape.

In addition, in the sanitary foil packaging body 1 according to the present invention, the difference in each part between the outer dimensions (width × depth × height) of the film 4 and the dimensions of the bundle (width × depth × 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 foil packaging body 1 according to the present invention.

In the sanitary foil paper packaging body 1 according to the present invention, the air outlet forming portion 50 for forming the ejection opening 60, which is an overlapping packaging concerned, is provided to fold the sanitary foil paper 2 back. A pair of first easy heat improvement (5A, 5A) separated from the depth direction (3D) extending along the width direction (3W) in which the bent frame (2C) extends and is orthogonal to the width direction (5A, 5A), and the depth direction It extends along (3D) and is a range surrounded by a pair of second easy heat improvements 5B and 5B connecting the ends of the pair of first easy heat improvements 5A and 5A. Here, the easy heat improvement 5A, 5B refers to a line easily opened by the line, for example, a dotted line or a slit line provided with uncut portions at appropriate intervals. In addition, it may be a line formed by reducing the thickness of the film.

In addition, in the outlet forming part 50 according to the present invention, characteristically, the pair of the first easy heat improvement (5A, 5A) is connected to the second heat improvement (5B, 5B) (P1, P1). ) From the bundle (3) toward the central portion in the width direction of the bundle (3), the end constriction portion 51 which is gradually closer to each other and constricted therebetween, and a pair of first easy thermal improvement (5A, 5A), the end constriction portion 51 From the side toward the central portion in the width direction of the bundle 3, the widening portion 52 gradually dissipates from each other and widens therebetween, and the pair of first easy thermal enhancements 5A, 5A, the widening portion 52 Further, as the bundle 3 faces the central part in the width direction, the width between them gradually increases and expands outward in the depth direction until the length between them becomes longer than at least the length of the second heat improvement 5B. While forming a shape having 53, in particular, the length (JW) between the first easy thermal improvement between the end constriction portion 51 and the widening portion 52 is, in the width direction (3W) of the bundle 3 ) 10% or less of the length (L1), preferably 1.6 to 8.3%, and the length (SW) between the first easy heat improvement (5A, 5A) in the width portion 53 is the width direction of the bundle (3) (3W) 60% or less of the length L1, preferably 45 to 57%.

In the sanitary foil packaging body 1 according to the present invention, since the outlet forming portion 50 has a shape having such an end constricting portion 51, a widening portion 52, and a widening portion 53, the outlet forming portion When removing within the range of (50), first, at the position of the end constriction portion 52, a corner portion P of an acute angle at a position between the first easy heat improvement 5A and the second easy heat improvement 5B ( 5 and 6) are formed. In other words, since the end constriction 51 is arranged so that the pair of first thermal enhancements 5A are close to each other from the end of the second easy thermal enhancement 5B along the depth direction, when these are removed, the end constriction position is At, corner portions P and P having an acute angle with the end position of the second column line 5B facing outward in the depth direction as a vertex are formed.

In addition, in the sanitary foil packaging body 1 according to the present invention, since the outlet forming portion 50 has a shape having such an end constriction portion 51, an enlarged portion 52, and a light width portion 53, the above When the range of the ejection port forming portion 50 is removed, free frame pieces 61 and 61 including an edge in a range from the end constriction portion 51 to the width light portion 53 are formed. That is, the pair of first easy heat improvement 5A, 5A according to the present invention is closer to the center portion in the width direction of the bundle 3, first at the end constriction portion 51, and also at the widening portion 52. It is further away from the width portion 53 to the outer edge in the depth direction than the end of the second easy thermal line 5B, so that the edge E1 and the edge in the range from the end constriction portion 51 to the width portion 53 A free border formed by a flexible film 4 in which a range connecting the outer position (P2) in the depth direction of the bundle (3) than the end of at least the second easy heat improvement (5B) of the part (P) and the width part is formed of a flexible film (4) It becomes the side 61.

In the sanitary foil packaging body 1 according to the present invention, since the outlet 60 associated with the outlet forming portion 50 is formed, the pull-out property and fall prevention property are excellent. In addition, the take-out property includes the fact that the sanitary foil paper can be pulled out smoothly, and that the next sheet or part of the set exposed after pulling out one sheet or one set is easy to stand on its own and is easy to grasp.

In the sanitary foil packaging body 1 according to the present invention, since it is wide open at a position corresponding to the width portion 53, the resistance at the time of pulling out is small, and it is easy to pull out smoothly. Also, it is easy to grab the first one. In particular, the length (SW) between the first easy heat improvement (5A, 5A) in the light width portion 53 is less than 60% of the width direction of the bundle, and an excessively wide opening is not formed, so that it can be prevented from falling. It is secured with other configurations. On the other hand, in particular, as shown in Fig. 5, after taking out one sheet or one set, the frame 20E at the root portion of the next one or one set of exposed portions 20 is moved to the corner portion P. Enter and be supported. At that time, the edge piece 61 positioned on the opposite edge side of the edge portion P where the edge portion 20E of the sanitary foil paper 2 fits tightly is the exposed portion 20 of the sanitary foil paper 2 ) Is leaned on, and the edge 20E of the sanitary foil 2 is pressed toward the edge portion P, so that the fit is maintained. Accordingly, the self-reliance and fall prevention properties of a portion 20 of the following sanitary foil paper become excellent.

In addition, since the bundle 3 has a pop-up structure, like the sanitary foil paper packaging body 1 according to the present invention, a part of the sanitary foil paper 3 that is drawn out after that when one sheet or one set is taken out When the edge 20E and the surface of 20 are exposed from the outlet 60 toward the outlet while moving in the depth direction 3D, they are guided by the edge of the outlet 60. In the sanitary foil paper packaging body 1 according to the present invention, since the width of the outlet 60 increases from the position between the end constriction portion 51 and the widening portion 52 toward the end constriction portion position, the sanitary foil paper 2 When a part 20 of) is pulled out, the edge 20E of the sanitary foil 2 is easily guided to the corner P. In addition, in particular, since the width between the end constriction portion 51 and the widening portion 52 is narrowed to 10% or less of the length of the bundle 3 in the depth direction (3D), the surface of the sanitary foil 2 is bordered. It is supported reliably at, and the fall prevention property is improved. In addition, if the distance between the first easy heat improvement 5A and 5A is within a range of 10% or less, and a connection portion 54 having a constant spacing between the pair of first easy heat improvement is provided, a more hygienic foil paper (2) It becomes easier to support the surface of the wall, and the fall prevention property becomes higher.

Here, in the end constriction part 51 and the widening part 52, it is preferable that the pair of 1st easy heat improvement 5A, 5A is curved. Since the edge E of the outlet 60 becomes a smooth curve, the guide of the sanitary foil 2 by the edge is made smoothly, and the lead-out property becomes more excellent.

In addition, the overall shape of the width light portion 53 is not particularly limited, but a circular, elliptical, or chamfered rectangle having a curved edge is preferable as shown in the illustrated example. It is difficult to get caught in the frame when withdrawing, making it easier to withdraw smoothly.

In the sanitary foil packaging body 1 according to the present invention, the length PW in the width direction 3W of the bundle 3 of the first easy thermal improvement 5A, 5A is the length in the width direction of the bundle 3 It is shorter than (L2) and is particularly preferably 87 to 97%. If it exceeds 97%, it becomes difficult for the edge 20E of the sanitary foil 2 to enter the corner P.

In addition, the length EW of the second easy thermal improvement 5B in the sanitary foil packaging body 1 according to the present invention is 3 to 16 of the length L1 of the bundle 3 in the depth direction 3D. It is preferably %. If it is within this range, the edge 20E becomes easy to enter the corner part P.

In the sanitary foil packaging body 1 according to the present invention, the width Bh of the frame piece 61, that is, the corner portion P1 (one of the corner portions P), and the corresponding width portion 53 The length from the line (Bb) connecting the point (P2) of the edge of the border (line (Bb) passes through the edge (P1) from the tangent line of the outer edge of the width portion 53) to the opening edge (E) (Bh) is preferably 8 to 24 mm. In addition, in the line Bb connecting the edge portion P and the edge portion of the width portion 53, the edge position P2 of the width portion 53 is a position where the width Bh becomes the longest. In the range of the width Bh, it can be sufficiently pressed and held as long as it is the size of a general sanitary foil paper.

On the other hand, in the sanitary foil package 1 according to the present invention, the first easy heat improvement 5A and the second easy heat improvement 5B consist of a dotted line or a slit having an uncut portion at an appropriate position as described above. However, more preferably, in the end constriction portion 51 and the widening portion 52, the first easy heat improvement 5A is made a slit that communicates inward and out, and the connection portion 54 and the widening portion 53 In this case, it is preferable to use a dotted line of 0.5 mm to 3.0 mm of tie and 1.0 mm to 7.00 mm of cut. In the connection portion 54 and the width portion 53, more preferably, the tie is 1.5 mm to 2.5 mm and the cut is 2.0 mm to 5.0 mm. It is difficult to tear at the time of transportation or loading, and it becomes the thing which is easy to break with a finger. In addition, it is preferable that the 2nd easy heat improvement 5B is made into the dotted line in which the position where the edge part P is cut, or especially the slit provided with the uncut part in the center part of the depth direction 3D. When configured with slits and dotted lines in this way, as shown in FIG. 6, while pressing the position X1 between the end constriction portion 51 and the widthwise edge 1E of the package 1 at the ceiling surface portion with a finger, the end constriction portion When 51 is moved away from the rim 1E, the end constriction portion 51 becomes a detached handle portion, and when the handle portion is pulled toward the end constriction portion 51 on the opposite side, the first easy thermal improvement (5A) ) And the outlet forming portion 50 surrounded by the second easy heat improvement 5B is removed smoothly, so that the opening 60 can be easily formed, and the opening property becomes excellent.

Here, as a specific flexible resin film material constituting the film 4 according to the present invention, polyethylene film, polypropylene film, polyester film, polyethylene terephthalate film, nylon film, vinylidene chloride film, ethylene vinyl A single layer film of an alcohol copolymer, a laminated film suitably laminated including these films, or a gas barrier film in which surface treatment such as aluminum vapor deposition was applied to these films can be exemplified. However, from the viewpoint of cost, a polypropylene film and a polyethylene film are suitable. In particular, a non-stretched polypropylene film (CPP) excellent in heat adhesion is preferred.

The thickness of the film 4 may be appropriately selected in consideration of flexibility, cost, gas permeability, and thermal adhesion at the time of packaging, but preferably, the thickness measured in accordance with JIS P 8118 (1998) is 20 to 60 μm, It is preferable that the softness measured based on the handle metric method according to JIS L 1096 (2010) E method is 5.0 to 50.0 cN. If the thickness and softness involved, the film is less likely to be torn, and it is easy to make it excellent in pop-up properties.
