Description

  The present invention relates to a toilet roll, a toilet roll product in which the toilet roll is packaged, and a method for manufacturing the toilet roll, and particularly to a toilet roll having excellent portability.

Toilet rolls mainly used for defecation and wiping after urination are well-known products. This toilet roll generally has a structure in which a long toilet paper is wound around a paper tube having substantially the same width as that, and only a necessary length is continuously unwound and cut. In many cases, perforations extending in the paper width direction are formed at predetermined intervals in the longitudinal direction of the paper in order to facilitate cutting during use.
On the other hand, toilet rolls of this type are extremely necessary and are therefore widely used. For example, department stores other than houses, restrooms such as stations where the public stands such as stations, event venues, etc. It is common to have a regular toilet and a public toilet.
JP 05-000121 A

However, in a restroom or the like shared by the public as described above, a state where the toilet roll is used up may be left unattended, and defecation may not be possible.
In addition, it is heard that the toilet roll was used up after defecation, and experienced a situation where it was impossible to leave the toilet.
Conventionally, in such a situation, a so-called pocket tissue in which a suitable number of folded tissue papers excellent in portability are packaged is often used for emergency purposes.
However, many pocket tissues are not water-degradable and are often not recommended for use in a restroom or the like. Furthermore, when using the pocket tissue for wiping after defecation, a complicated operation is required in which a plurality of sheets are stacked after being taken out from the packaging bag one by one. In particular, when performing defecation in a restroom, etc., such as when going out, it is often performed while holding the clothes so that the clothes do not come into contact with the floor or holding a bag or the like. Pocket tissue that requires manipulation was difficult to use.
On the other hand, in the restrooms and the like shared by the public as described above, many users feel uneasy about hygiene because they are shared by an unspecified number of people.
In order to eliminate such anxiety, for example, a toilet seat in which a toilet seat sheet disclosed in Japanese Patent Application Laid-Open No. 05-000121 and a disinfectant (to wipe the toilet seat by applying to toilet paper) is used for cleaning the toilet seat However, no measures have been taken for toilet rolls that may be touched by an unspecified number of people, so we refrain from using the provided toilet rolls and use pocket tissue while feeling inconvenience. There are many people who do.
Also, when traveling abroad to unhygienic areas, many people feel uneasy about the hygiene aspects of the toilet rolls they have prepared, and want to refrain from using them.
In view of the above problems, a main object of the present invention is to provide a sanitary toilet roll that is excellent in portability and can be carried.

The present invention that has solved the above problems is as follows.
<Invention of Claim 1>

Thereafter, the portable toilet roll is crushed from the body surface direction into a flat shape having an elliptical end surface with a long side length of 60 to 85 mm and a short side length of 10 to 30 mm. Production method.

(Function and effect)
The toilet roll excellent in portability described in claim 1 can be manufactured.

  As described above, according to the present invention, a sanitary toilet roll which is excellent in portability and can be carried is provided.

Next, embodiments of the present invention will be described in detail below with reference to the drawings.
Embodiments of the present invention will be described in detail below with reference to FIGS. FIG. 1 is a perspective view for explaining a toilet roll 1 of the present embodiment.
The toilet roll 1 of the present invention has a structure in which a long toilet paper 10 is wound around a paper tube 11 having substantially the same width.
As shown in FIGS. 1 (a) and 1 (b), the toilet roll 1 of the present invention is characteristically formed from a body surface (also referred to as a peripheral surface) 1a after the toilet paper 10 is wound around a paper tube. It is crushed and flattened. The crushing direction is indicated by an arrow P in FIG.

Although the said toilet paper 10 can use the thing of the known composition which shows water-decomposability, about paper thickness, it shall be 50-200 micrometers. If the paper thickness is less than 50 μm, it will be unreliable when used, and if it exceeds 200 μm, it will not be possible to obtain a sufficient winding length sufficient for one use when it has excellent portability like pocket tissue.
Further, the number of plies of the toilet paper 10 is not particularly limited, but a general one-ply or two-ply is preferable because it is easy to use existing manufacturing equipment. The paper thickness means the thickness of the plurality of plies when the number is a plurality of plies regardless of the number of plies.
For example, specific physical properties of the toilet paper 10 are a basis weight of 13 to 23 g / m ² , a dry tensile strength of 60 to 400 cN based on JIS P 8113, and a wet tensile strength of 0 to 80 cN. Examples of the raw material include pulp fibers such as waste paper pulp and virgin pulp.

The toilet paper 10 is desirably formed with perforations extending in the paper width direction L1 at predetermined intervals in the paper longitudinal direction, although not shown. It becomes easy to cut at a desired position. The interval between the perforations is preferably 100 to 250 mm.
The perforation line can be formed by a known perforation roll (sewing blade roll) facility. That is, a plurality of blades are arranged along the width direction on a roll wider than the width L1 of the toilet paper 10 to form a blade row, and this blade row is rolled at the same pitch as the interval between the perforation lines of the toilet paper 10. By making a plurality of perforation rolls provided in the circumferential direction of the paper abut against the toilet paper traveling while rotating, perforation lines extending in the width direction of the toilet paper can be formed at predetermined intervals in the longitudinal direction.

Here, in this invention, it is good to make the tensile strength in a perforation line a little stronger than a normal toilet roll on the relationship which crushes after winding up the toilet paper 10. FIG. Specifically, it is good to set it as 400-800 cN. By crushing, the perforation line becomes difficult to tear. The “tensile strength at the perforation line” here is the tensile strength at the time of drying measured in accordance with the tensile property test method defined in JIS P 8113, and the tensile strength measured across the perforation line. Means.
The tensile strength at the perforation line can be adjusted by adjusting the tie length, which is the connecting part at the perforation line, and the cut length, which is the same split part, or the tie cut, which is the ratio of this tie length to the cut length. This can be done by adjusting the ratio. More specifically, it can be adjusted by replacing with a perforation roll having a blade row having a desired tie cut length and tie cut ratio. The tensile strength can be adjusted by adjusting the pressing pressure of the perforation roll to the paper (pressing force on the paper per unit width of the paper (kgf / cm)) and the winder speed (paper winding speed). It can also be adjusted by adjustment.
On the other hand, the toilet paper 10 may carry a known disinfectant or antibacterial agent. Examples of such bactericides and antibacterial agents include silver ions, copper ions, salts thereof, alcohols, and the like that are known to have known bactericidal and antibacterial effects.

On the other hand, the paper tube 11 has a characteristic basis weight of 140 to 300 g / m ² , a diameter L3 before crushing of 38 to 45 mm, and a length L1 of 100 to 120 mm.
If the basis weight of the paper tube 11 is less than 140 g / m ² , it will be difficult to ensure sufficient strength, and if it exceeds 300 g / m ² , portability will deteriorate, and when crushed, it will be perpendicular to the crushing direction. The toilet paper 10 that is rolled up due to excessive folds is likely to be damaged, and the quality becomes unstable.
If the diameter of the paper tube 11 is less than 38 mm, there is a high possibility that the paper tube 11 cannot be installed on the existing paper holder, and even if it can be installed, the roll is difficult to rotate and may not be pulled out smoothly. On the other hand, if it exceeds 45 mm, the diameter when the necessary amount of toilet paper 10 suitable for carrying, which will be described later, is wound up becomes too thick, and portability deteriorates.
If the length of the paper tube 11 is not in the range of 100 to 120 mm, there is a high possibility that the paper tube 11 cannot be installed in the paper holder.
On the other hand, the material and the manufacturing method of the paper tube 11 can adopt known materials and methods, and are not particularly limited. Examples of the composition of the paper tube 11 include pulp fibers such as waste paper pulp and virgin pulp. In the present invention, it is desirable that the paper tube is also excellent in water disintegration.

On the other hand, the toilet roll 1 of the present invention sets the length of the toilet paper 10 to 3 to 20 m. When the present inventors investigated about the usage-amount of a general toilet roll, it discovered that it was about 240-100 cm in the wiping after a defecation, and about 80-100 cm in the wiping after a urination in general. From the viewpoint of the amount used and portability, the amount used is less than 3 m, and if it exceeds 20 m, portability deteriorates in relation to the diameter after winding described later.
Moreover, the toilet roll 1 of this invention makes it the diameter L2 after toilet paper winding before crushing to 55 +/- 5mm. If the winding diameter in the length of the toilet paper 10 is less than 50 mm, the winding density increases too much, and the possibility that the toilet paper 10 is broken during crushing described later increases. On the other hand, when the thickness exceeds 60 mm, the winding density becomes too low, and there is a high possibility that the paper tube 11 may come off or the toilet paper 10 may be separated, and the portability is also deteriorated.

Furthermore, the shape after the crushing of the toilet paper 10 of the present invention is a flat shape having an end surface elliptical shape in which the length of the long side Lx is 60 to 85 mm and the length of the short side Ly is 10 to 30 mm.
By adopting this flat shape, it is excellent in portability, and in use, from both edges of the flat shape (from both ends of the long side Lx of the end face 1b) as shown by the arrow X in the figure, the shaft center By lightly pushing toward the front, it can be restored and deformed to a state close to a true cylinder before being crushed and can be easily set in the holder, and can be pulled out smoothly during use.
Here, if the long side Lx is less than 60 mm, it is thick and inferior in portability, and if it exceeds 85 mm, it is difficult to restore the true cylindrical shape and it is difficult to set in a paper holder. Moreover, it becomes easy to obstruct the smooth drawer | drawing-out about the curl of the toilet paper 10 excessively.
Similarly, if the short side Ly exceeds 30 mm, the thickness increases and the portability becomes inferior. If it is less than 10 mm, it is difficult to restore the true cylindrical shape and it is difficult to set the paper holder. In addition, the smooth pull out of the toilet roll is liable to be hindered from being smoothly pulled out.

<Manufacturing method of toilet roll>
Subsequently, the manufacturing method of the toilet roll 1 of this invention is demonstrated. The manufacturing method of the toilet paper 10 and the paper tube 11 according to the present invention can adopt a known manufacturing method. At this time, the paper tube 11 is adjusted to have a desired basis weight by adjusting the basis weight of the pulp fiber.
On the other hand, the toilet roll 10 can be wound around the paper tube 11 by a known winding facility. The method of tail sealing is not particularly limited, and a known method can be adopted.
On the other hand, the crushing P of the body surface 1a may be performed by placing the toilet roll 1 on a horizontal table so that the body surface 1a is up and down and pressing a flat surface against the body surface 1a from above. It can also be done by placing it on a horizontal table so that the end face 1b is up and down and sandwiching it between parallel plates from both sides.
After crushing, for example, the product is packaged in a packaging bag to be described later. It will be excellent in distribution, marketability, and portability.

<Toilet roll products>
Next, the toilet roll product X1 of the present invention will be described with reference to FIG. This toilet roll product X1 according to this embodiment is obtained by packaging the above-described toilet roll 1 of the present invention with a packaging bag 2.
The material for the packaging bag 2 is not particularly limited. Examples thereof include paper and resin films.
A resin film is preferable in that it is excellent in waterproofness and moisture proofness and can suitably protect water-decomposable toilet paper and can easily maintain a hygienic state.
Due to the nature of the product, the packaging bag is preferably opaque. In this case, for example, an opaque resin film or paper may be used as the raw material. Specifically, regarding this transparency, the opacity based on JIS P 8148 (2001) is 30% or more, preferably 50% or more. There should be. A partially transparent window may be provided so that the remaining amount inside can be visually recognized.

Examples of the resin film include a polypropylene resin film, a polyethylene resin film, and a polyethylene terephthalate resin film. The resin film may be a laminate film in which several films are laminated.
As the polyethylene resin film, a linear or linear short chain branched polyethylene resin composition film can be used. A laminate film of polyethylene terephthalate and a linear or linear short chain branched polyethylene resin composition is suitable.
The linear or linear short chain branched polyethylene resin composition is also referred to as LLDPE, and can be produced by a known method using a metallocene catalyst. This LLDPE is excellent in heat sealability. As another film, a polyethylene resin composition other than LLDPE, for example, a high versatility called LDPE obtained by a high pressure method having a density of 0.850 to 0.950, preferably 0.910 to 0.936 is high. An inexpensive one can also be used.
The polyethylene resin composition may contain a known additive other than the polyethylene resin, for example, a preservative, an antioxidant, an antiblocking agent, a slip agent, and the like as a secondary material.

Here, the laminating method of the resinous film is a dry laminating method in which each resin is formed into a film in advance, and this film is laminated with an epoxy adhesive, an acrylic adhesive, or the like, and each molten resin is removed from the T-die. An extrusion laminating method in which a thin film is extruded and laminated as front and back surfaces can be employed. The extrusion lamination method is preferably employed because it can be manufactured at low cost and the resin type can be arbitrarily selected.
On the other hand, the thickness of the resin film is 5 to 100 μm, preferably 10 to 40 μm, particularly preferably 15 to 25 μm. If the thickness is less than 5 μm, the adhesive strength is insufficient, and if it exceeds 100 μm, the resin cost is excessive and may cause trouble in the equipment.
The thickness of the laminate layer can be adjusted as appropriate by adjusting the thickness of the film used for forming the laminate layer and the amount of extrusion.

On the other hand, as a method for forming the packaging bag 2 using a resin film or a toilet roll packaging method, a known bag-making technique or packaging technique can be used. For example, after the toilet roll 1 is covered with a resin film, a method of adhering the edge portion by ultrasonic fusion, thermal fusion (heat sealing), or the like can be employed. As the specific shape and shape of the packaging bag, a known bag forming technology such as three-way closed packaging, four-sided closed packaging, jointed closed packaging, gusset packaging, caramel packaging, pillow packaging, and reverse pillow packaging is suitable. Adopted.
On the other hand, in the toilet roll product X1 of this embodiment, a zipper 20 that can be freely opened and closed is preferably formed on the packaging bag 2 as shown in the drawing. The zipper is preferably formed by fitting a pair of male strips 21 and female strips 22 disclosed in, for example, JP-A-2006-69645, JP-A-2007-119043, and the like. As a result, it is possible to ensure a suitable portability even when the apparatus is not used up.

  The present invention can also be used for roll papers other than toilet rolls.
