By the way, in recent years, the problem of plastic waste has become more serious worldwide, and in order to improve the global environment, there is a demand to replace plastic packaging materials with other materials. The packaging bag described in Patent Document 1 is also made of plastic, and there is still room for improvement in the selection of the material of the packaging bag for packaging a plurality of sanitary paper rolls.

In addition, the dimensions of the packaging bag for packaging multiple sanitary paper rolls should be designed appropriately from the viewpoint of the appearance of the package and the occurrence of tearing of the packaging bag during the packaging process, transportation, product display, actual use, etc. There is a need.

It is an object of the present invention to provide a sanitary paper roll package that is friendly to the global environment, and that is capable of suppressing breakage of the packaging bag of the package and achieving aesthetics of the package. That's what it is.

A sanitary paper roll packaging body according to the present invention is a sanitary paper roll packaging body in which a plurality of sanitary paper rolls are wrapped in a paper material to wrap around the body, and the packaging portion of the body of the sanitary paper roll packaging body is parallel to the axis of the sanitary paper roll. The length Y between both ends of the paper material cut and developed in the direction orthogonal to the cutting direction is 95.0% of the theoretical circumferential length L of the plurality of sanitary paper rolls arranged in parallel in the sanitary paper roll package. It is characterized by being 0% or more and 105.0% or less.

Therefore, the possibility of tearing the packaging bag of the packaging body is reduced. By setting the winding density of the two-ply sanitary paper roll according to the present invention to the above numerical range, the sanitary paper roll is less likely to be crushed by pressing during bonding in the packaging process, and the sanitary paper roll can easily cope with deformation. Therefore, when the packaging bag of the package is picked up and carried with one hand, the finger pressure is dispersed and is less likely to be concentrated on one point of the packaging bag, and the packaging bag is less likely to tear.

In addition, in the sanitary paper roll package according to the present invention, the basis weight of the paper material of the sanitary paper roll package is 40.0 g/m ² or more and 80.0 g/m ² or less, and the density of the paper material is 0.60 g. /cm ³ or more and 0.90 g/cm ³ or less.

By setting the basis weight of the paper material of the sanitary paper roll package according to the present invention to the numerical range, the packaging bag of the package is less likely to break when picked up and carried with one hand, and the manufacturing cost can be reduced. .

FIG. 1 is an overall perspective view of a sanitary paper roll package 1 according to one embodiment of the present invention, FIG. 2 is a top plan view of the sanitary paper roll package 1 according to this embodiment, and FIG. FIG. 4 is a plan view of the packaging bag 10 of the sanitary paper roll package 1, with the top and bottom of the sanitary paper roll package 1 peeled off, and the paste margin 11 peeled off. FIG. 2 is a plan view of the packaging bag of 1, which is developed by peeling off the adhesive on the top and bottom of the sanitary paper roll packaging body 1 and cutting it along the cutting line CL. The uncut unfolded wrapping paper in FIG. 3 is 10B, and the cut and unfolded wrapping paper in FIG. 4 is 10C.

A sanitary paper roll package 1 according to the present invention is formed by wrapping a plurality of sanitary paper rolls 2 with a paper material (paper material). As shown in FIG. 1, a sanitary paper roll package 1 according to the present embodiment is formed by caramel-wrapping four toilet rolls 2 arranged in two rows and two columns with a paper material. Examples of the paper material include coated paper, kraft paper, and laminated paper. Also, the paper material is obtained by papermaking a slurry containing a pulp component, which is a fiber raw material. Pulp components include wood pulp, non-wood pulp, and waste paper pulp. The total number of sanitary paper rolls 2 housed in the sanitary paper roll package 1 is preferably an even number of 8 rolls or less, more preferably 4 rolls. Further, the caramel packaging may adopt a known one, for example, the packaging means described in Patent Document 2 may be adopted. Specifically, for example, first, the sanitary paper roll 2 placed on the flat paper material is wrapped so as to be rolled up, and the overlapping portions in the rolling direction are adhered. This adhesion is made, for example, by heat sealing. Next, the surplus portion beyond the end face position of the sanitary paper roll 2 is folded into the end face side of the sanitary paper roll 2 (folded along the folding line indicated by the symbol FL in FIG. 3). Then, the tip edges of the triangular piece or the trapezoidal piece formed during folding are adhered to each other to cover the sanitary paper roll 2 from the upper and lower end faces. A known device can be used as a device for such caramel packaging.

The sanitary paper roll 2 according to the present invention comprises a one-ply (or two-ply) paper portion 20 and a paper tube (core) 21 . The winding diameter of the sanitary paper roll 2 is preferably 100 mm or more and 130 mm or less, more preferably 105 mm or more and 125 mm or less. The outer diameter of the core of the paper tube 21 is preferably 37 mm or more and 42 mm or less, more preferably 38 mm or more and 41 mm or less. Here, the number of plies represents the number of superimposed sanitary paper rolls.

In addition, in the sanitary paper roll package 1 according to the present invention, the wrapping portion of the trunk portion of the sanitary paper roll package 1 is cut parallel to the axis of the sanitary paper roll 2 and developed. The length Y between them (see FIGS. 1 and 4) is 95.0% or more and 105.0% or less of the later-described theoretical circumferential length L of the plurality of sanitary paper rolls 2 arranged in parallel in the sanitary paper roll package 1. ing. The Y/L is preferably 96.5% or more and 103.5% or less, more preferably 98.0% or more and 102.0% or less.

The length Y is such that after peeling off the adhesive on the top and bottom of the sanitary paper roll package 1 (the top and bottom surfaces of the sanitary paper roll package 1 in FIG. It can be said that it is the length in the width direction (of the sanitary paper roll 2) when it is cut and developed (along the cutting line CL of 1) (see FIG. 4).

The theoretical circumferential length L is obtained by arranging the sanitary paper rolls 2 stored in the sanitary paper roll package 1 in the same arrangement as when the sanitary paper roll package 1 was stored (unwrapped state), as viewed from above. When the roll 2 is regarded as a plurality of equal circles circumscribing, the total length of the common circumscribed lines of the plurality of equal circles (marks CSL1 and CSL2 in FIG. 2) and the circumference of one circle (marks CAL1 and CAL2 in FIG. 2) It can be said that the length is the sum of Specifically, when the radius of one sanitary paper roll 2 is r (mm), the number of sanitary paper rolls 2 in the width direction is nX, and the number of sanitary paper rolls 2 in the length direction is nX. Assuming nY, the theoretical circumference L (mm) can be expressed as 2πr+4×(nX−1)r+4×(nY−1)r.

In this embodiment, by adopting a paper material for the material of the packaging bag 10 for packaging a plurality of sanitary paper rolls 2, the sanitary paper roll packaging body 1 friendly to the global environment is realized, and the degree of slackness of the packaging bag 10 is realized. is adjusted appropriately, it is possible to achieve both suppression of tearing of the packaging bag and aesthetics of the package. Regarding the degree of slackness, when the length Y is less than 95.0% of the theoretical circumference L, the packaging bag is easily torn due to a tightly wound state, and the length Y is less than the theoretical circumference. If it exceeds 105.0% of the length L, the packaging bag will loosen and the aesthetic appearance of the sanitary paper roll package will deteriorate.

As a further specific example of this embodiment, the basis weight of the paper material of the packaging bag 10 of the sanitary paper roll package 1 is 40.0 g/m ² or more and 80.0 g/m ² or less, and the density of the paper material is 0.0 g/m 2 or more and 80.0 g/m 2 or less. It may be 60 g/cm ³ or more and 0.90 g/cm ³ or less. The basis weight is preferably 42.5 g/m ² or more and 70.0 g/m ² or less, more preferably 45.0 g/m ² or more and 60.0 g/m ² or less. The density is preferably 0.65 g/cm ³ or more and 0.85 g/cm ³ or less, more preferably 0.70 g/cm ³ or more and 0.80 g/cm ³ or less.

According to this embodiment, the packaging bag 10 of the sanitary paper roll package 1 is not easily broken when picked up and carried with one hand, and the manufacturing cost can be reduced. Further, according to this embodiment, since the bulk and the bonding between fibers are optimized, the packaging bag 10 of the sanitary paper roll package 1 is not easily broken when picked up and carried with one hand, and the rigidity is optimized, so that packaging workability is improved. will be superior. On the other hand, if the basis weight is less than 40.0 g/m ² , the sanitary paper roll package is likely to tear when picked up with one hand, and if it exceeds 80.0 g/m ² , the cost will increase. If the density is less than 0.60 g/cm ³ , the sanitary paper roll package is likely to be torn when picked up with one hand because it is bulky and has ^few interfiber bonds. Packaging workability will be inferior.

As further specific examples of this embodiment, the winding length and winding density in the case of the first specific example in which the number of plies of the sanitary paper roll 2 is one and the second specific example in which the number of plies is two will be described below.

As a first specific example in which the sanitary paper roll 2 is one ply (single ply), the winding length of the sanitary paper roll 2 is 50 m or more and 150 m or less, and the winding density of the sanitary paper roll 2 is 0.65 m/cm ² or more and 1.30 m. /cm ² or less. The winding length is preferably 60 m or more and 140 m or less, more preferably 70 m or more and 130 m or less. The winding density is preferably 0.80 m/cm ² or more and 1.25 m/cm ² or less, more preferably 1.00 m/cm ² or more and 1.20 m/cm ² or less.

The winding density is calculated by the following formula by dividing the value obtained by multiplying the winding length by the number of plies by the cross-sectional area of the roll excluding the cross-sectional area of the paper tube.
Winding density (m/cm ² ) = winding length (m) x number of plies/cross-sectional area of roll (cm ² )
Here, the cross-sectional area of the roll is represented by S=πr ² -πrc ² where r (mm) is the radius of the sanitary paper roll 2 and rc (mm) is the radius of the paper tube.

According to this embodiment, the replacement frequency of the sanitary paper roll 2 is reduced, and the packaging bag 10 of the sanitary paper roll package 1 is moderately heavy when picked up from both sides with one hand and carried. The possibility of tearing the packaging bag 10 is reduced. With this configuration, the sanitary paper roll 2 is less likely to be crushed by being pushed during bonding in the packaging process, and the sanitary paper roll 2 can easily cope with deformation. When carrying, the finger pressure is dispersed and is less likely to be concentrated on one point on the packaging bag 10, and the packaging bag 10 is less likely to tear. On the other hand, if the winding length is less than 50 m, the frequency of replacement of the sanitary paper roll increases. If the winding length exceeds 150 m, the mass of the sanitary paper roll increases and the sanitary paper roll package becomes heavy, so that when the sanitary paper roll package is picked up from both sides with one hand, the packaging bag is easily torn. If the winding density of the sanitary paper roll is less than 0.65 ^m /cm ² , the sanitary paper roll is likely to be crushed by pressing during adhesion in the packaging process. When the sanitary paper roll package is picked up with one hand, the finger pressure is concentrated on one point of the packaging bag, which makes the packaging bag easily torn.

As a second specific example in which the sanitary paper roll 2 is two-ply, the winding length of the sanitary paper roll 2 is 25 m or more and 75 m or less, and the winding density of the sanitary paper roll 2 is 0.65 m/cm ² or more and 1.30 m/cm ² or less. may be The winding length is preferably 30 m or more and 70 m or less, more preferably 35 m or more and 65 m or less. The winding density is preferably 0.80 m/cm ² or more and 1.25 m/cm ² or less, more preferably 1.00 m/cm ² or more and 1.20 m/cm ² or less.

According to this embodiment, the replacement frequency of the sanitary paper roll 2 is reduced, and the packaging bag 10 of the sanitary paper roll package 1 is moderately heavy when picked up from both sides with one hand and carried. 10 is less likely to break. With this configuration, the sanitary paper roll 2 is less likely to be crushed by being pushed during bonding in the packaging process, and the sanitary paper roll 2 can easily cope with deformation. When carrying, the finger pressure is dispersed and is less likely to be concentrated on one point on the packaging bag 10, and the packaging bag 10 is less likely to tear. On the other hand, if the winding length is less than 25 m, the frequency of replacement of the sanitary paper roll 2 increases. When the roll package 1 is pinched from both sides with one hand, the packaging bag 10 is easily torn. If the winding density of the sanitary paper roll 2 is less than 0.65 m/cm ² , the sanitary paper roll ² is likely to be crushed by pressing during bonding in the packaging process. When the sanitary paper roll package 1 is picked up with one hand, the finger pressure concentrates on one point of the packaging bag 10, so the packaging bag 10 is easily torn.

Traditionally, sanitary paper rolls, such as toilet paper and kitchen paper, have generally been packaged in sets of multiple rolls and wrapped in plastic film to prevent dust and dirt from adhering to them. For example, Patent Document 1 discloses a packaging body in which sanitary paper rolls are wrapped in two rows with a plastic film, and the gripping margin between the sanitary paper rolls generated when packaging in two rows is It describes a package in which the position of the opening line formed on the packaging bag is devised so that the opening line is not broken when gripped.

By the way, in recent years, the problem of plastic waste has become more serious worldwide, and in order to improve the global environment, there is a demand to replace plastic packaging materials with other materials. The packaging bag described in Patent Document 1 is also made of plastic, and there is still room for improvement in the selection of the material of the packaging bag for packaging a plurality of sanitary paper rolls.

In addition, the dimensions of the packaging bag for packaging multiple sanitary paper rolls should be designed appropriately from the viewpoint of the appearance of the package and the occurrence of tearing of the packaging bag during the packaging process, transportation, product display, actual use, etc. There is a need.

Furthermore, in view of the fact that paper differs from plastic film in terms of stretchability, in order to achieve both suppression of tearing of the packaging material in paper packaging and aesthetics of the packaging, we independently determined the degree of slackness of the packaging paper and the sanitary paper. It is necessary to adjust the winding density of the roll.

According to the present invention, by adopting a paper material as the material of the packaging bag 10 for packaging a plurality of sanitary paper rolls 2, the sanitary paper roll package 1 that is friendly to the global environment is realized, and the slackness of the packaging bag 10 is reduced. Since the degree is optimized, it is possible to achieve both suppression of tearing of the packaging bag 10 and aesthetics of the sanitary paper roll package 1 .
