Disclosure of Invention
Problems to be solved by the invention
However, if a plurality of toilet paper rolls are packaged using only a packaging substrate including a paper substrate, the paper substrate may have a significantly lower tensile strength in the CD direction than in the MD direction, and thus, due to the characteristics of the paper substrate, the packaging substrate may be undesirably broken at the opening perforation line by a tensile force in the MD direction acting on the paper substrate when packaging the toilet paper rolls, or may be difficult to be broken along the opening perforation line when opening.
The present invention aims to prevent accidental breakage at a perforation line for unsealing when packaging toilet paper rolls, and to easily enable the packaging base material to be ruptured along the perforation line for unsealing when unsealing in a toilet paper roll package in which a plurality of toilet paper rolls are packaged by the packaging base material comprising the paper base material.
Means for solving the problems
The toilet paper roll package according to the present invention is characterized by comprising a packaging substrate comprising a paper substrate, wherein a plurality of toilet paper rolls are packaged in a state of being aligned in a direction perpendicular to the axial direction of the plurality of toilet paper rolls, and perforation lines for unsealing are formed in the packaging substrate along the MD direction of the paper substrate.
According to this configuration, since the opening perforation line is formed in the packaging substrate along the MD direction of the paper substrate, accidental breakage of the opening perforation line due to the stretching force in the MD direction acting on the paper substrate when packaging the toilet paper roll can be prevented, and the packaging substrate can be easily broken along the opening perforation line in the CD direction of the paper substrate when opening.
In the toilet paper roll package according to the present invention, the opening perforation line extends along the axial direction of the toilet paper roll so as to be located between two toilet paper rolls adjacent to each other in an aligned manner in a direction perpendicular to the axial direction of the toilet paper roll.
According to this configuration, at the time of unsealing, the packaging base material can be easily ruptured along the line of perforations for unsealing in the CD direction of the paper base material by simply pressing between two toilet paper rolls that are aligned and adjacent in the direction perpendicular to the axial direction of the toilet paper rolls in the packaging base material.
Further, in the toilet paper roll package according to the present invention, the opening perforation line extends in a direction perpendicular to the axial direction of the toilet paper roll so that a part thereof is located between two toilet paper rolls adjacent in an aligned manner in the direction perpendicular to the axial direction of the toilet paper roll.
According to this configuration, when opening, a part of the opening perforation line passing between two toilet paper rolls aligned and adjacent in the direction perpendicular to the axial direction of the toilet paper rolls in the packaging base material is pushed in and split, so that the packaging base material can be easily split along the CD direction of the paper base material with the split part as a starting point.
In the toilet paper roll package according to the present invention, an auxiliary perforation line is formed in the packaging base material, the auxiliary perforation line extends in a direction perpendicular to the axial direction of the toilet paper roll or extends in the axial direction of the toilet paper roll, and a part of the auxiliary perforation line intersects the opening perforation line between two toilet paper rolls aligned and adjacent in the direction perpendicular to the axial direction of the toilet paper roll.
According to this configuration, when opening, the intersecting portion of the opening perforation line and the auxiliary perforation line in the packaging base material is pushed in, and a part of the opening perforation line is broken, so that the packaging base material can be easily broken along the CD direction of the paper base material with the broken portion as a starting point.
Effects of the invention
According to the present invention, in a toilet paper roll package in which a plurality of toilet paper rolls are packaged with a packaging substrate including a paper substrate, accidental breakage of an opening perforation line due to a tensile force acting in the MD direction of the paper substrate when packaging the toilet paper rolls can be prevented, and at the time of opening, the packaging substrate can be easily broken along the opening perforation line in the CD direction of the paper substrate, so that the toilet paper roll package can be opened smoothly.

< first embodiment >
Fig. 1 is a perspective view of a toilet paper roll package 1 in which a plurality of toilet paper rolls 2 are candy-packaged according to a first embodiment of the present invention, and fig. 2 is a plan view of the front side of the toilet paper roll package 1 shown in fig. 1. In fig. 2, among the four toilet rolls 2, the right two laminated toilet rolls are set to 2f, the left two laminated toilet rolls are set to 2s, the central axis of the toilet roll 2f is set to 2fA, and the central axis of the toilet roll 2s is set to 2sA.
The toilet paper roll package 1 of the present invention is formed by wrapping a plurality of toilet paper rolls (toilet paper rolls in this embodiment) 2 with their both end surfaces aligned in a direction perpendicular to the axial direction thereof with a wrapping base material 10. The packaging substrate 10 is provided with an opening perforation line PL on the paper substrate, and further, a process (for example, a printing process) required for packaging the toilet paper roll 2 is performed. For convenience of explanation, the side of the toilet paper roll package 1 having the adhesive portion is referred to as the back side, and the side opposite to the back side is referred to as the front side. In order to facilitate removal of toilet paper roll 2 after unsealing and prevent accidental detachment of the remaining toilet paper roll 2 after removal of toilet paper roll 2, the length of the unsealing perforation line PL is preferably 1.4 to 1.9 times the width dimension of toilet paper roll 2, and more preferably 1.5 to 1.8 times the width dimension of toilet paper roll 2.
As shown in fig. 1, the packaging substrate 10 of the package 1 according to the present embodiment has a pair of top and bottom surfaces 10T and 10B, which are provided to face each other, and a peripheral surface 10P.
As shown in fig. 1, a package 1 according to the present embodiment is formed by candy wrapping 4 toilet paper rolls 2 in 2 rows×1 rows×2 layers with a wrapping material 10. The packaging substrate 10 comprises at least a paper substrate. Examples of the paper base material include coated paper, kraft paper, laminated paper, cellophane, and overcoated paper having an overcoated layer for ensuring water repellency. The paper base material is obtained by papermaking a slurry containing a pulp component as a fiber raw material. Examples of the pulp component include wood pulp, non-wood pulp, and waste pulp. In the present embodiment, the packaging substrate 10 is a glossy single-sided paper having a glossy outer surface.
In order to exert the effects of the present invention, the tensile strength in the MD direction of the paper base material in the packaging base material 10 is preferably 2.5 to 7.0kN/m, more preferably 3.5 to 6.0kN/m, and even more preferably 4.0 to 5.5kN/m. If the tensile strength in the MD direction of the paper base material in the packaging base material 10 is less than 2.5kN/m, the packaging base material 10 may be unexpectedly broken when the toilet paper roll 2 is packaged, and if the tensile strength in the MD direction of the paper base material in the packaging base material 10 is more than 7.0kN/m, the bending strength in the MD direction of the packaging base material 10 becomes high, and it may be difficult to fold the packaging base material 10 in the MD direction when the toilet paper roll 2 is packaged.
In order to exert the effects of the present invention, the tensile strength in the CD direction of the paper base material in the packaging base material 10 is preferably 1.0 to 3.5kN/m, more preferably 1.5 to 3.0kN/m, and even more preferably 1.7 to 2.7kN/m. If the tensile strength in the CD direction of the paper base material in the packaging base material 10 is less than 1.0kN/m, the packaging base material 10 may be accidentally ruptured along the perforation line PL for unsealing in the CD direction of the paper base material, and if the tensile strength in the CD direction of the paper base material in the packaging base material 10 is more than 3.5kN/m, the packaging base material 10 becomes difficult to rupture along the perforation line PL for unsealing in the CD direction of the paper base material.
In order to exert the effects of the present invention, the thickness of the packaging substrate 10 is preferably 45 μm to 130. Mu.m, more preferably 50 μm to 110. Mu.m, and still more preferably 65 μm to 90. Mu.m. If the thickness of the packaging substrate 10 is thicker than 130 μm, when the packaging substrate 10 is broken along the line PL for opening at the time of opening, the broken end face of the packaging substrate 10 at the line PL for opening contacts the finger with a large pressure, and if the thickness of the packaging substrate 10 is thinner than 45 μm, the packaging substrate 10 cannot obtain a sufficient tensile strength.
In the present invention, as the paper base material of the packaging base material 10, for example, cellophane can be preferably used. The glassine paper is a tissue paper manufactured as follows: the raw paper obtained by high-consistency pulping and papermaking of chemical pulp is passed through a calender and heat and pressure are applied to crush the gaps between fibers, thereby producing a tissue paper. Glassine paper has the properties of high smoothness, gloss, high density, high air permeability (i.e., the time it takes a certain amount of air to pass through a certain area of paper under a certain pressure, in other words, low air permeability), translucency, etc.
By using cellophane for the paper substrate of the packaging substrate 10, there are advantages such as the following.
(1) From the appearance of the package 1, the toilet paper roll 2 wrapped by the wrapping substrate 10 can be easily distinguished through the transparent or translucent heat-seal layer and the translucent cellophane. Further, characters and graphics printed on the surface of cellophane, which is the inner surface of the packaging substrate 10, can be seen from the outside of the packaging substrate 10, and the degree of freedom in design is improved.
(2) Since cellophane has high air permeability, the toilet paper roll 2 as a packaged object, which is packaged by the packaging substrate 10, is not easily affected by external moisture. For other specific examples of the paper base material and the packaging base material 10, the description of patent document 2 can be referred to.
The candy wrapper may be in a known manner. Specifically, for example, a continuous sheet of packaging material pulled out from an original roll of roll paper is cut to a predetermined length to form packaging material 10, and then toilet paper roll 2 is wrapped in roll form by packaging material 10, and the ends of packaging material 10 overlapping in the roll direction are bonded (heat-sealed) to each other via a heat-seal layer described later. Next, the remaining portion of the packaging substrate 10 beyond the end face position of the toilet paper roll 2 is folded into the end face side of the toilet paper roll 2. Then, the front edge portions of the triangular pieces or trapezoidal pieces of the packaging base material 10 formed when the remaining portions of the packaging base material 10 are folded in are bonded (heat-sealed) to each other via a heat-seal layer described later, and the toilet paper roll 2 is wrapped from the upper and lower end face sides. As a device for performing such candy wrapping, a known device can be used.
The packaging base material 10 in the toilet paper roll package 1 is bonded by heat sealing as described above. In order to adhere by the above method, a heat seal layer to which a heat sealing agent that performs an adhesive function when heat is applied is provided on the paper base material of the packaging base material 10. As a material constituting the heat seal layer, for example, a polyolefin resin, another thermoplastic resin, or the like can be used.
As shown in fig. 1 and 2, the toilet paper roll package 1 according to the present embodiment includes a package substrate 10 including a paper substrate, the package substrate 10 packages four toilet paper rolls 2f and 2s in a state of being aligned in a direction perpendicular to an axial direction of a central axis 2fA (or 2 sA) thereof, and an opening perforation line PL is formed in the package substrate 10 along an MD direction of the paper substrate. The opening perforation line PL (and an auxiliary perforation line described later) is composed of a connecting portion and a non-connecting portion, and the pitch of the connecting portion (or the non-connecting portion) can be designed in consideration of the effects of the present invention.
According to this configuration, since the opening perforation line PL is formed in the packaging substrate 10 along the MD direction of the paper substrate, accidental breakage of the opening perforation line due to the tensile force acting in the MD direction of the paper substrate when packaging the toilet paper roll 2 can be prevented, and the packaging substrate 10 can be easily ruptured in the CD direction of the paper substrate along the opening perforation line PL when opening.
As shown in fig. 1 and 2, the toilet paper roll package 1 according to the present embodiment has an opening perforation line PL extending along the axial direction of the central axis 2fA (or 2 sA) of the toilet paper roll 2f (or 2 s) so as to be located between two toilet paper rolls 2 adjacent in an aligned manner in the direction perpendicular to the axial direction of the central axis 2fA (or 2 sA) of the toilet paper roll 2f (or 2 s).
According to this configuration, at the time of opening, the packaging substrate 10 can be easily ruptured along the opening perforation line PL in the CD direction of the paper substrate by simply pressing between two toilet paper rolls 2 in the packaging substrate 10 that are aligned and adjacent in the direction perpendicular to the axial direction of the central axis 2fA (or 2 sA) of the toilet paper roll 2f (or 2 s).
In order to achieve the effect of the present invention, the basis weight of the packaging substrate 10 is preferably 30g/m 2 Above and 65g/m 2 Hereinafter, it is more preferably 35g/m 2 Above and 60g/m 2 Hereinafter, it is more preferably 45g/m 2 Above and 55g/m 2 The following is given. According to this structure, the packaging substrate 10 is not easily producedCracking, good water resistance can be obtained, and sealing strength can be improved. That is, if the basis weight of the packaging substrate 10 is less than 30g/m 2 The packaging substrate 10 is easily broken and good water resistance cannot be obtained. In addition, if the basis weight of the packaging substrate 10 exceeds 65g/m 2 The heating temperature of the heat-seal layer at the time of sealing is lowered, and good sealing strength (lowering of sealing strength) is not obtained.
Conventionally, a toilet paper roll package in which toilet paper rolls are packaged and stored as a film for a packaged object is known, and such a package is described in patent document 1, for example, in which a plastic film for packaging a plurality of toilet paper rolls in a state of being aligned in a direction perpendicular to an axial direction thereof is provided, and the toilet state of the toilet paper rolls is maintained by the plastic film so as to prevent dust and dirt from adhering. An opening perforation line is formed on the plastic film so that the plastic film can be broken along the opening perforation line when the toilet paper roll is used, and the toilet paper roll can be taken out.
However, 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 replace the raw material of packaging with other raw materials from plastic, and in packaging for packaging paper products such as toilet paper rolls, the raw material of packaging is also replaced with paper from plastic films, and for example, patent document 2 proposes packaging for packaging paper products such as toilet paper rolls using a packaging substrate including a paper substrate.
However, if a plurality of toilet paper rolls are packaged using only a packaging substrate including a paper substrate, the paper substrate may have a significantly lower tensile strength in the CD direction than in the MD direction, and thus, due to the characteristics of the paper substrate, the packaging substrate may be accidentally broken at the opening perforation line by a tensile force in the MD direction acting on the paper substrate when packaging the toilet paper rolls, or the packaging substrate may be difficult to break along the opening perforation line when opening.
That is, for example, in the step of pulling out the continuous packaging substrate sheet from the original roll, or in the folding step of folding the remaining portion of the packaging substrate beyond the end face position of the toilet paper roll into the end face side of the toilet paper roll after the toilet paper roll is wound up by the packaging substrate at the time of candy wrapping, when the toilet paper roll is wrapped from the upper and lower end face sides, a tensile force acts on the continuous packaging substrate sheet or the packaging substrate in the MD direction of the paper substrate, and thus when the opening perforation line is formed in the continuous packaging substrate sheet or the packaging substrate in the CD direction of the paper substrate, the tensile force acts in the direction of tearing the opening perforation line when the continuous packaging substrate sheet is pulled out from the original roll or when the toilet paper roll is wrapped from the upper and lower end face sides at the time of candy wrapping, the opening perforation line may be ruptured.
According to the present embodiment, since the perforation line PL for unsealing is formed in the MD direction of the paper base material in the packaging base material 10, when the toilet paper roll 2 is packaged, accidental breakage of the continuous packaging base material sheet or the packaging base material 10 at the perforation line PL for unsealing due to a tensile force acting in the MD direction of the paper base material can be prevented, and the packaging base material 10 can be easily ruptured in the CD direction of the paper base material along the perforation line PL for unsealing at the time of unsealing, and thus unsealing can be smoothly performed.
< second embodiment >
In the second embodiment of the present invention, as described above, unlike the first embodiment, the MD direction of the paper base material is the circumferential direction of the toilet paper roll package 1', and the opening perforation line PL extends along the circumferential direction of the toilet paper roll package 1'.

In the present embodiment, as shown in fig. 4, the opening perforation line PL is formed such that a part thereof is formed between the central axis 2fA of the toilet paper roll 2f and the central axis 2sA of the toilet paper roll 2s, and the remaining part thereof extends outward in the width direction.
According to this configuration, at the time of opening, a part of the opening perforation line PL passing between the two toilet paper rolls 2 aligned and adjacent in the direction perpendicular to the axial direction of the central axis 2fA (or 2 sA) of the toilet paper roll 2f (or 2 s) is pushed in and broken, and the packaging substrate 10' can be easily broken in the CD direction of the paper substrate along the opening perforation line PL with the broken part as a starting point.
In the toilet paper roll package 1 according to the first embodiment and the toilet paper roll package 1' according to the second embodiment, one straight line-shaped perforation line PL for unsealing is provided, but in the present invention, the perforation line PL for unsealing may include a curved line or may be constituted by a plurality of perforation lines, as long as the effect of the present invention is achieved.
