Description

[Technical field]

[0001] The present invention relates to a package in which a plurality of rolls of sanitary tissue paper or a stack of sanitary tissue paper are bundled together and packaged in paper material. [Background technology]

[0002] Conventionally, packages have been known in which multiple pieces of sanitary thin paper such as toilet paper or kitchen paper in a roll form (hereinafter also referred to as "roll-form sanitary thin paper") or cartons serving as sanitary thin paper laminates containing laminates of sanitary thin paper such as tissue paper or wipers (hereinafter also referred to as "sanitary thin paper cartons") are bundled together and wrapped in film. For example, Patent Documents 1 and 2 describe such packages in which an identification code such as a barcode used in a POS (Point Of Sale) system is printed on the packaging film.

[0003] Incidentally, in recent years, the problem of plastic waste has become more serious worldwide, and in order to improve the global environment, it is desired to change packaging materials from plastic to other materials. Also, in a package in which rolled sanitary thin paper or a sanitary thin paper laminate is packaged, it has been proposed to use a wrapping paper with a heat seal layer to heat seal package the rolled sanitary thin paper or the sanitary thin paper laminate (Patent Document 3). Therefore, it is considered to use a wrapping paper with a heat seal layer to package a package in which multiple rolls of sanitary thin paper or sanitary thin paper cartons are packaged together. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2008-120431 A [Patent Document 2] JP 2009-096474 A [Patent Document 3] Patent Publication No. 2021-070501 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in a package in which multiple rolls of sanitary thin paper or sanitary thin paper cartons are heat-sealed using wrapping paper with a heat-seal layer, when an identification code such as a barcode is printed (for example by printing) on ​​the wrapping paper, just as in a package wrapped in film, depending on the position of the code, wrinkles may occur around the heat-sealed and welded heat-seal layer (hereinafter also referred to as the "heat-sealed portion") due to the temperature difference during heat sealing.These wrinkles may distort the identification code, resulting in misreading or poor reading of the identification code.

[0006] The present invention aims to suppress misreading or poor reading of identification codes in a package in which multiple rolls of sanitary tissue paper or sanitary tissue paper laminates are bundled together and heat-sealed using wrapping paper with a heat seal layer, by preventing wrinkles caused by temperature differences during heat sealing around the heat seal portion from distorting the identification code to the extent that this causes misreading or poor reading. [Means for solving the problem]

[0007] The package according to the present invention is a package in which a plurality of rolls of sanitary tissue paper or sanitary tissue paper laminates are bundled together and heat-sealed using wrapping paper having a heat-seal layer, and is characterized in that an identification code is displayed on the outer surface of the wrapping paper around the heat-seal layer that is heat-sealed during the heat-seal packaging, in an unaffected area that is not affected by wrinkles that occur due to temperature differences during the heat-sealing.

[0008] With this configuration, the identification code is displayed on an unaffected part of the outer surface of the wrapping paper that is not affected by wrinkles that occur around the heat-sealed part due to the temperature difference during heat-sealing. Therefore, the identification code is not distorted to the extent that it would be misread or read incorrectly due to wrinkles that occur around the heat-sealed part due to the temperature difference during heat-sealing, thereby preventing misreading or read errors of the identification code.

[0009] In addition, the packaging body according to the present invention is characterized in that the wrapping paper wraps a plurality of rolls of sanitary thin paper together, the plurality of rolls of sanitary thin paper are wrapped around the body and wrapped in the wrapping paper in a state in which both end faces are aligned in a direction perpendicular to the axial direction, the wrapping paper has the heat seal layer extending in the axial direction of the rolls of sanitary thin paper at one end of the plurality of rolls of sanitary thin paper in the waist direction, the other end of the plurality of rolls of sanitary thin paper in the waist direction is overlapped and heat sealed to the heat seal layer at a position where at least a portion of the end abuts against the outer periphery of one of the plurality of rolls of sanitary thin paper aligned in the direction perpendicular to the axial direction of the rolls of sanitary thin paper, and the identification code is displayed on the outer surface of the wrapping paper at a position where at least a portion of the end abuts against the outer periphery of another of the plurality of rolls of sanitary thin paper aligned in the direction perpendicular to the axial direction of the rolls of sanitary thin paper.

[0010] With this configuration, the multiple rolls of sanitary thin paper in the wrapping paper are heat-sealed at both ends in the waist direction using one roll of sanitary thin paper as a receiver, so tearing of the wrapping paper due to the effect of being pressed in during heat sealing can be suppressed. Also, since the identification code is displayed on the outer surface of the wrapping paper in a portion where at least a portion of the identification code abuts against the outer periphery of another roll of sanitary thin paper among the multiple rolls of sanitary thin paper arranged in a row in a direction perpendicular to the axial direction of the roll of sanitary thin paper, even if the wrapping paper slackens between the multiple rolls of sanitary thin paper arranged in a row in a direction perpendicular to the axial direction of the roll of sanitary thin paper, the identification code is less likely to be distorted by the influence of this slack, so misreading or reading errors of the identification code can be more reliably suppressed.

[0011] Furthermore, the packaging body according to the present invention is characterized in that the identification code is displayed on a second unaffected portion around the folded portion of the wrapping paper that is not affected by wrinkles that occur due to the folding of the wrapping paper.

[0012] With this configuration, the identification code is not distorted to the extent that it would be misread or read incorrectly due to wrinkles that occur around the folded parts of the wrapping paper (for example, the folded parts on the top and sides of the package, or the corners) caused by the folding of the wrapping paper, and misreading or read errors of the identification code can be more reliably prevented.

[0013] In addition, the packaging material according to the present invention is characterized in that the background color of the wrapping paper is white, and the identification code is printed on the outer surface of the wrapping paper.

[0014] With this configuration, the identification code can be displayed simply and clearly on the outer surface of the wrapping paper.

[0015] The packaging body according to the present invention is characterized in that the packaging paper is one-sidedly glossy paper with a glossy outer surface, and the identification code is printed and displayed on the glossy surface of the packaging paper.

[0016] This configuration allows the identification code to be printed more clearly. Effect of the Invention

[0017] According to the present invention, the identification code is displayed on the outer surface of the wrapping paper in an unaffected area that is not affected by wrinkles that occur around the heat-sealed area due to the temperature difference during heat-sealing. Therefore, the identification code is not distorted to the extent that it would cause misreading or reading errors due to wrinkles that occur around the heat-sealed area due to the temperature difference during heat-sealing, and misreading or reading errors of the identification code can be suppressed.

[0019] The embodiment of the package according to the present invention will be described in detail with reference to Figures 1 to 6. However, the present invention is not limited to this embodiment.

[0020] As described above, the sanitary thin paper according to the present invention includes toilet paper, kitchen paper, tissue paper, wipers, etc., and in the description of this specification and the claims, "roll-shaped sanitary thin paper" refers to sanitary thin paper such as toilet paper or kitchen paper rolled into a roll, and "sanitary thin paper laminate" refers to sanitary thin paper such as tissue paper, wipers, etc. that is folded and laminated. In the following, in the first embodiment, a form in which a plurality of roll-shaped sanitary thin paper sheets are carton-wrapped in a paper material (hereinafter also referred to as "wrapping paper") is described, and in the second embodiment, a form in which a stack of a plurality of cartons serving as a sanitary thin paper laminate containing the sanitary thin paper laminate is carton-wrapped in wrapping paper is described.

[0021] In addition, in the present specification and claims, the terms "top surface" and "bottom surface" refer to the surfaces defined by the packaging bag in which multiple rolls of sanitary tissue paper or sanitary tissue paper laminates are packaged and exposed to the outside. However, these terms are used merely for convenience and do not, of course, define absolute positions in the direction of gravity. The same applies to terms such as "top" and "bottom."

[0022] Furthermore, in this specification, the claims, and the drawings, the "height direction," the "width direction," and the "length direction" are perpendicular to each other, and the "roll parallel direction" corresponds to either the above-mentioned "width direction" or "length direction."

[0023] In addition, in the description of this specification, the claims, and the drawings, an "identification code" is an optically readable code that indicates various information regarding various items, and includes, for example, one-dimensional codes such as barcodes and two-dimensional codes such as QR codes (registered trademark).

[0024] For ease of explanation, the overall perspective views of FIG. 1 and FIG. 5 show contents in a see-through state.

[0025] First Embodiment Fig. 1 is an overall perspective view of a package 1 in which a plurality of rolled sanitary thin paper 2 according to the first embodiment of the present invention are caramel-packaged, Fig. 2 is a plan view of the back surface of the package 1 according to this embodiment, Fig. 3 is a plan view of the top surface of the package 1 according to this embodiment, and Fig. 4 is a plan view of the package bag 10 of the package 1 according to this embodiment, which is unfolded after the heat-sealed layers 12 at the top and bottom of the package bag 10 and the heat-sealed layers 12 at the glue tabs 11 are peeled off. In Fig. 2, of the four rolled sanitary thin paper 2, the two on the right are designated 2f and the two on the left are designated 2s, the central axis of the rolled sanitary thin paper 2f is designated 2fA, the central axis of the rolled sanitary thin paper 2s is designated 2sA, and the unfolded package in Fig. 4 is designated 10D.

[0026] The packaging body 1 according to the present invention is formed by wrapping and wrapping a plurality of roll-shaped sanitary thin papers (toilet rolls in this embodiment) 2 in a state where both end faces are aligned in a direction perpendicular to the axial direction, with a paper material (paper materials). As shown in FIG. 1, the packaging body 1 according to the present embodiment is formed by wrapping four toilet rolls 2 in two rows and two columns with a paper material. Examples of the paper material include coated paper, craft paper, and laminated paper. The paper material is obtained by papermaking a slurry containing a pulp component, which is a fiber raw material. Examples of the pulp component include wood pulp, non-wood pulp, and recycled paper pulp. In this embodiment, the packaging paper is a one-sided gloss paper with a glossy outer surface. A known type of caramel packaging can be used for the caramel packaging. Specifically, for example, first, the toilet roll 2 placed on the paper material formed in a flat shape is wrapped in a roll, and the overlapping parts in the rolling direction are bonded (heat-sealed) via a heat seal layer described later. Next, the excess portion extending beyond the end face position of the sanitary paper roll 2 is folded toward the end face side of the sanitary paper roll 2 (folded in mountain folds and valley folds along the mountain fold lines and valley fold lines indicated by the symbols UFL and DFL in FIG. 4, respectively).Then, the leading edge portions of the triangular or trapezoidal pieces formed during folding are bonded together to cover the upper and lower end faces of the toilet roll 2.A known device can be used as a device for performing this type of caramel packaging.

[0027] In addition, the paper material in the packaging body 1 is bonded by the heat seal method as described above. For bonding by the above method, the paper material (the glue margin 11 and one or both sides of the folded part) is provided with a heat seal layer 12 to which a heat seal agent that exhibits an adhesive function when heat is applied is previously applied. As shown in FIG. 4, the heat seal layer 12 is applied to the outer surface of the unfolded packaging paper 10D, that is, the portion shown by diagonal hatching in the figure, that is, the glue margin 11 and the peripheral portion of the packaging paper 10D. That is, as shown in FIG. 4, the heat seal layer 12 is provided in a U-shape on the peripheral side of one surface of the rectangular packaging paper. When the toilet roll 2 is packaged, the heat seal layer 12 on the bottom surface 10B side and the top surface 10T side of the packaging body 1 is the bottom surface sealing heat seal layer 12B and the top surface sealing heat seal layer 12T, respectively. For example, polyolefin resins and other thermoplastic resins can be used as the material constituting the heat seal layer 12.

[0028] As shown in Figs. 1-4, the package 1 according to this embodiment is a package in which four toilet rolls 2 are bundled together and heat-sealed using a wrapping paper having a heat-seal layer 12, and an identification code 14 is displayed on a non-affected portion 13 that is not affected by wrinkles that occur around the heat-sealed layer (heat-sealed portion) 12 that is heat-sealed during heat-seal packaging, on the periphery of the outer peripheral surface of the wrapping paper, due to the temperature difference during the heat-sealing. Here, "the identification code 14 is displayed" includes, for example, a case in which the identification code 14 is printed and displayed on the outer surface of the wrapping paper by a printing process, or a case in which a sticker with the identification code 14 printed thereon is affixed to the outer surface of the wrapping paper and displayed on the outer surface of the wrapping paper. In addition, the "non-affected portion that is not affected by wrinkles" refers to a portion that is not affected by wrinkles, as well as a portion that is not distorted by wrinkles to the extent that the identification code 14 is misread or not read properly.

[0029] With this configuration, the identification code 14 is displayed on the unaffected portion 13 on the outer surface of the wrapping paper, which is not affected by wrinkles that occur around the heat-sealed portion 12 due to the temperature difference during heat-sealing. Therefore, the identification code 14 is not distorted to the extent that it would cause misreading or reading errors due to the influence of wrinkles that occur around the heat-sealed portion 12 due to the temperature difference during heat-sealing, and misreading or reading errors of the identification code 14 can be suppressed.

[0030] More specifically, in the package 1 according to the present embodiment, as shown in Figs. 1 to 4, the four toilet rolls 2 are wrapped around the body and wrapped in wrapping paper in a state in which both end faces are aligned in a direction perpendicular to the axial direction, and the wrapping paper has a heat seal layer 12E extending in the axial direction of the toilet rolls 2 at one end in the waist circumference direction of the four toilet rolls 2 (the surface of the pasting margin 11 in Fig. 4), and one of the toilet rolls 2f, 2s in two rows aligned in a direction perpendicular to the axial direction of the toilet rolls 2 is The heat seal layer 12 at one end in the waist direction is overlapped and heat sealed at a portion where at least a portion of the heat seal layer 12 at one end in the waist direction abuts against the outer periphery of the other toilet roll 2s (the toilet roll on the left side in Figure 2) of the two rows of toilet rolls 2 arranged in parallel in a direction perpendicular to the axial direction of the toilet roll 2, on the outer surface of the wrapping paper.

[0031] With this configuration, the wrapping paper is heat-sealed at both ends in the waist direction of the four toilet rolls 2 using one toilet roll 2f as a receiver (see FIG. 1), so that tearing of the wrapping paper due to the influence of pushing during heat sealing can be suppressed. Also, since the identification code 14 is displayed on the outer surface of the wrapping paper at a portion where at least a part of the identification code 14 abuts against the outer periphery of another toilet roll 2s among the four toilet rolls 2 arranged in a row in a direction perpendicular to the axial direction of the toilet roll 2, even if the wrapping paper slackens between the four toilet rolls 2 arranged in a row in a direction perpendicular to the axial direction of the toilet roll 2, the identification code 14 is unlikely to be distorted by the influence of this slack, so that misreading or reading failure of the identification code 14 can be more reliably suppressed.

[0032] In the present invention, as shown in Fig. 2, the identification code 14 may be displayed in an area overlapping the central axis 2sA of another toilet roll 2s when viewed from the back side of the packaging body 1. This configuration also makes the identification code 14 less likely to be distorted, thereby preventing misreading or reading errors of the identification code 14.

[0033] Furthermore, in this embodiment, the identification code 14 is disposed in a second unaffected portion that is not affected by wrinkles that occur around the folded portion of the wrapping paper due to the folding of the wrapping paper. The folded portion of the wrapping paper is a folded portion where the wrapping paper is folded on the top surface 10T or bottom surface 10B of the packaging body 1, or a corner between the peripheral surface of the packaging body 1 and the top surface 10T (or bottom surface 10B), and is a place where wrinkles occur around the periphery due to the folding of the wrapping paper, and in this embodiment, the identification code 14 is displayed avoiding the place (at a position away from the place) as shown in Figures 1, 2, and 4. Here, the "second unaffected portion that is not affected by wrinkles" means a portion that is not affected by wrinkles, as well as a portion that is not distorted by wrinkles to the extent that the identification code 14 is misread or read improperly.

[0034] With this configuration, the identification code 14 is not distorted to the extent that it causes misreading or reading failure due to the influence of wrinkles that occur around the folded portion of the wrapping paper due to the folding of the wrapping paper, and misreading or reading failure of the identification code 14 can be more reliably suppressed.

[0035] Additionally, in this embodiment, the background color of the wrapping paper is white, and the identification code 14 is printed on the outer surface of the wrapping paper.

[0036] With this configuration, the identification code 14 can be printed and displayed simply and clearly on the outer surface of the wrapping paper. In order to achieve the effects of the present invention, it is preferable that the ISO whiteness (ISO2470-1) of the background color of the wrapping paper is 70% or more, preferably 80% or more, and more preferably 85% or more. The whiteness value increases depending on the amount of bleaching agent used to bleach the fiber pulp before it is made into paper, i.e., the unbleached pulp, and the amount of dye having a bluish color such as blue or purple that is added to the bleached pulp when it is made into paper.

[0037] In this embodiment, as described above, the wrapping paper is one-sided glossy paper with a glossy outer surface, and the identification code 14 is printed on the glossy surface of the wrapping paper. This configuration allows the identification code 14 to be printed more clearly, and makes it possible to further reduce misreading and reading errors of the identification code.

[0038] Conventionally, in a package in which a plurality of rolls of sanitary thin paper or sanitary thin paper laminates are bundled and wrapped in a film, an identification code such as a barcode used in a POS system is printed on the packaging film, as described in, for example, Patent Document 1 and Patent Document 2. However, in recent years, in order to improve the global environment, it has been desired to change the packaging material from plastic to other materials, and it has been proposed to use wrapping paper with a heat seal layer to heat seal the rolls of sanitary thin paper or the sanitary thin paper laminate in a package in which rolls of sanitary thin paper or sanitary thin paper laminates are wrapped (Patent Document 3). Therefore, it is considered to use wrapping paper with a heat seal layer to wrap a package in which a plurality of rolls of sanitary thin paper or sanitary thin paper cartons are bundled and wrapped.

[0039] However, in a package in which multiple rolls of sanitary thin paper or sanitary thin paper cartons are heat-sealed using wrapping paper with a heat seal layer, when an identification code such as a barcode is printed on the wrapping paper, as is the case with packages wrapped in film, depending on the position of the code, wrinkles may occur around the heat-sealed and welded heat seal layer (heat seal portion) due to temperature differences during heat sealing.These wrinkles may distort the identification code, resulting in misreading or poor reading of the identification code.

[0040] According to this embodiment, the identification code 14 is displayed on the unaffected portion 13 on the outer surface of the wrapping paper, which is not affected by wrinkles that occur around the heat-sealed portion due to the temperature difference during heat-sealing. Therefore, the identification code 14 is not distorted to the extent that it would cause misreading or reading errors due to wrinkles that occur around the heat-sealed portion due to the temperature difference during heat-sealing, and misreading or reading errors of the identification code 14 can be suppressed.

[0041] <Second embodiment> In the second embodiment of the present invention, as described above, unlike the first embodiment, a stack of multiple cartons 3 as sanitary thin paper laminates containing sanitary thin paper laminates is wrapped in wrapping paper having a heat seal layer, and as in the first embodiment, the identification code is displayed in a location away from the heat seal portion (and the folded portion of the packaging body 1') on the circumferential surface as the outer surface of the wrapping paper and at a location where the surface of the contained item is abutted against the back of the wrapping paper. Therefore, it is possible to prevent misreading or poor reading of the identification code 14 by preventing the identification code from being distorted to the extent that it would be misread or poorly readable due to wrinkles that occur around the heat seal portion (and the folded portion of the packaging body 1') due to temperature differences during the heat sealing or due to folding of the wrapping paper during packaging.

[0042] Fig. 5 is an overall perspective view of a package 1' in which a stack of cartons 3 as a sanitary thin paper laminate containing a laminate of sanitary thin paper according to this embodiment is caramel-packaged, and Fig. 6 is a plan view of the back surface of the package 1' according to this embodiment. Of the various elements constituting the package according to this embodiment, those having similar functions are given the same reference numerals as in the first embodiment, and their explanations are omitted.

[0043] In this embodiment, similarly to the first embodiment, the package 1' is provided with a heat seal layer 12B for sealing the bottom surface, a heat seal layer 12T for sealing the top surface, and a heat seal layer 12E at one end in the waist direction.

[0044] In this embodiment, the package 1' is a substantially rectangular parallelepiped shape formed by caramel-wrapping a stack of cartons 3, and the folded parts where wrinkles are likely to occur around the folds due to folding of the wrapping paper include corners between adjacent long and short sides. In this embodiment, the identification code 14 is arranged at a position away from not only the heat seal layer 12E at one end in the waist circumference direction and the corners on the top surface 10T side and bottom surface 10B side of the package 1', but also the corners between adjacent long and short sides, as shown in Figures 5 and 6.

[0045] According to this embodiment, as in the first embodiment, the identification code 14 is displayed on the outer surface of the wrapping paper in a portion that is not affected by wrinkles that occur around the heat-sealed portion due to the temperature difference during heat-sealing. Therefore, the identification code 14 is not distorted to the extent that it would cause misreading or reading failure due to the influence of wrinkles that occur around the heat-sealed portion due to the temperature difference during heat-sealing or wrinkles that occur around the folded portion due to the folding, thereby suppressing misreading or reading failure of the identification code 14.

[0046] <Other> The present invention is not limited to the above-described embodiments or the modified examples described throughout the specification, and appropriate changes and modifications can be made without departing from the technical concept of the present invention.

[0047] For example, although the above embodiments relate to caramel packaging, the present invention is not limited to this and can be applied to various packaging formats such as gusset packaging and pillow packaging (see Patent Document 3 for specific packaging).

[0048] In addition, in the first embodiment described above, the packaging body 1 packages four rolls of sanitary thin paper in two rows, but this is not limited to this in the present invention, and it is sufficient if it packages multiple rolls of sanitary thin paper together.

[0049] In addition, in the above second embodiment, a stack of multiple cartons 3 containing a laminate of sanitary thin paper is packaged in wrapping paper having a heat seal layer, but this is not limited to this. A laminate of sanitary thin paper may be packaged in wrapping paper, and a stack of multiple such packages may be packaged in wrapping paper having a heat seal layer. [Explanation of symbols]
