(Function and effect)
In the toilet roll of the present invention, the paper tube is made water-degradable, and a water-soluble cleaning agent is loaded thereon. After using the toilet paper, the cleaning agent is removed from the paper tube by inserting the paper tube into the flush toilet. Elution and cleaning of toilet bowls and piping.

  Therefore, after using the toilet paper, the paper tube can be easily disposed of by being thrown into the toilet without being taken out of the toilet room, and since the toilet can be cleaned, the paper tube can be used without waste.

  In particular, in the present invention, the paper tube is formed of a paper tube base paper in which a plurality of water-decomposable base papers are laminated and integrated with a water-soluble adhesive so as to be water-decomposable. In this way, when the paper tube is put into the toilet, the paper tube base paper constituting the paper tube is quickly separated into the water-degradable base paper of each layer and is carried in contact with the water in the toilet. The detergent is also eluted quickly. Therefore, good water disintegration and cleaning effects are exhibited.

  Here, if the position where the cleaning agent is carried in relation to the paper tube is the outer surface of the paper tube, that is, the surface position of the paper tube base paper, the cleaning agent instantaneously contacts the water when the paper tube is put into the toilet. Thus, not only toilet piping but also toilet toilets, particularly the trap portion where the water reservoir is formed, can be effectively cleaned. Needless to say, the cleaning agent is supported on the outer surface of the paper tube, particularly on the outer surface of the water-degradable base paper.

  Further, assuming that the paper tube base paper is a laminate of three or more layers of water-decomposable base paper, the elution rate of the cleaning agent can be adjusted by supporting the cleaning agent on the water-decomposable base paper constituting the inner layer. That is, when the cleaning agent is supported on the inner layer water-degradable base paper, the elution of the cleaning agent is slightly delayed as compared with the case where the cleaning agent is supported on the outer surface. Therefore, when the cleaning agent is supported on the water-degradable base paper of the inner layer, it becomes possible to elute the cleaning agent not in the toilet trap but in the pipe connected to the toilet. It should be noted that the trap and the pipe can be effectively cleaned by combining the loading of the cleaning agent on the water-degradable base paper of the inner layer and the loading of the cleaning agent on the outer surface. At that time, in order to make the cleaning agent suitable for cleaning each part, the cleaning agent supported on the outer surface and the cleaning agent supported on the water-decomposable base paper constituting the inner layer may be used.

  Moreover, in the toilet roll, it is common to pull out and use the toilet paper with the paper holder support inserted in the paper tube, and the paper tube inner peripheral surface will slide with the support, If the cleaning agent is carried on the inner peripheral surface of the paper tube, the cleaning agent may be peeled off by sliding. Therefore, in the present invention, when the cleaning agent is carried on the outer surface of the paper tube, the cleaning agent is preferably carried on the outer peripheral surface of the paper tube. If the cleaning agent is supported on the outer peripheral surface of the paper tube in this way, there is no risk of the cleaning agent peeling off, and the cleaning effect of the paper tube when used after the toilet paper has been used up reliably can be obtained. Of course, even if the cleaning agent is supported on the water-degradable base paper constituting the inner layer of the paper tube base paper among the plurality of water-decomposable base papers constituting the paper tube base paper, there is no risk of the cleaning agent peeling off, The cleaning effect of the paper tube when used after the toilet paper has been used up.

  In addition, when carrying the cleaning agent on the outer peripheral surface, hold the two or three fingers in the paper tube and moisten the paper tube to elute the cleaning agent on the outer peripheral surface of the paper tube, A wiping aspect of wiping the toilet bowl is also possible.

  Here, as a method of loading the detergent on the water-degradable base paper, it is applied with a coater such as a size press, a gate roll coater, a bill blade coater, etc. together with a water-soluble polymer such as starch or CMC in a paper machine or the like. Can be performed. Moreover, you may apply | coat with the offcoater separately to the base paper made with the paper machine.

  On the other hand, in the present invention, the cleaning agent carried on the water-decomposable base paper constituting each layer may be different. Various cleaning agents suitable for piping and traps can be carried, or a plurality of cleaning agents difficult to be mixed as a solution can be carried. In addition, when the paper tube is put into the toilet, each cleaning agent is eluted in the water accumulated in the trap, so that each cleaning agent can be mixed in the trap to exert a cleaning effect. .

Moreover, in this invention, a cleaning agent is contained in the water-soluble adhesive for laminating and integrating water-degradable base papers . The cleaning agent content in the paper tube can be increased. In that case, the cleaning agent carried on the water-degradable base paper and the cleaning agent in the water-soluble adhesive for integrating the water-decomposable base papers are different .

  On the other hand, in the present invention, the paper tube is formed in such a manner that a plurality of strip-shaped paper tube base papers are spirally wound in a state of being partially overlapped in the width direction and adhered by glue at the overlapping portion, A cleaning agent may be contained in the paste disposed in the overlapping portion.

  In this way, it becomes possible to carry more cleaning agent on the paper tube. Moreover, even when the cleaning agent is included in the glue, the cleaning agent is prevented from being peeled off due to sliding with the paper holder support when the toilet roll is used. In addition, even if the cleaning agent is carried in the adhesive in this way, it can be manufactured without any change in the process for making the paper tube from the normal paper tube base paper, and thus the paper tube is made from a large amount of paper tube base paper. There is an advantage that the carrying amount of the cleaning agent can be increased without greatly changing the equipment.

  On the other hand, a desirable detergent component in the present invention is a surfactant such as a cationic surfactant, an anionic surfactant, a nonionic surfactant, and an amphoteric surfactant. It is suitable for cleaning toilet bowls and piping, and can be stably supported on paper tubes.

  Further, when at least one of acids and alkali components is contained in the cleaning agent, it is possible to remove scales and urine stones attached to the toilet, and to prevent adhesion, resulting in a paper tube with higher added value.

  As described above, according to the present invention, there is provided a toilet roll having a paper tube for a toilet roll that can be poured into a toilet after use and disposed, and that has added value.

It is a figure for demonstrating the toilet roll which concerns on this invention. It is explanatory drawing of the manufacturing process of the toilet paper which concerns on this invention. It is a figure for demonstrating the manufacturing method of the paper tube which concerns on this invention. It is sectional drawing of the paper tube base paper concerning this invention.

Embodiments of the present invention will be described below with reference to the drawings.
"Production example of toilet roll according to the present invention"
First, the manufacturing method of the toilet roll which concerns on this invention is demonstrated with reference to FIG.1 and FIG.2.
The manufacturing method of the toilet roll 10 according to the present invention includes a process (A) for manufacturing a long paper tube 11L, a log manufacturing process (B), and a cutting process (C).

  In the process of manufacturing the long paper tube 11L ((A) in FIG. 1), as shown in FIG. 2, two strips of paper tube base paper (paperboard) 12 and 12 are removed from the raw rolls 12A and 12A. Applying glue 30 at a predetermined position by the glue roll 13 while feeding each of them, and winding the glued portion around the shaft 15 by the core winder 14 in a spiral manner, then pulling out the shaft and defining according to the production type A long cylindrical paper tube 11 </ b> L is formed by cutting and aligning the length with the slitter 16.

  Each of the paper tube base papers 12 and 12 may use a different original fabric. For example, one of the paper tube base papers 12 and 12 may be printed, or each rice paper basis may be changed. Also in the present invention, the paper tube base papers 1 and 1 are not necessarily the same.

  Next, in parallel with or after the production of the long paper tube 11L, the log 10R is manufactured in the log manufacturing process ((B) in FIG. 1). Note that the log 10R is a general term in the industry. And an intermediate product having the same diameter as the final product and the width of the final product.

  In manufacturing the log 10R, toilet paper base sheets S1 and S1 having substantially the same width as the long paper tube 11L are fed out from the jumbo rolls JR and JR and wound around the log paper 10R continuously or stepwise to form the log 10R. . A known winder device X2 can be used for this winding. In the illustrated example, toilet paper base sheets S1 and S1 are fed from two jumbo rolls JR and JR to form a laminated continuous sheet S2 in the overlapping portion 51, and then a known contact embossing device 54 and perforation line forming device. After applying contact emboss CE and forming a perforation line (not shown) at 70, a winding device 75 is used to form a winding two-ply structure.

  In the embodiment shown in the drawing, sanitary thin paper is fed from two jumbo rolls to form a two-ply toilet paper base paper S2 having a laminated structure. It may be more than ply. Furthermore, in the case of a multi-ply structure, the basis weight, physical properties, and the like of each base paper need not be the same.

  Next, when the log 10R is manufactured in this way, the log 10R is moved to the subsequent log cutter facility X4 while being stocked as a plurality of logs by the known log accumulator X3. Then, as shown in (C) of FIG. 1, the log 10 </ b> R is cut into a product width by a known log cutter 76 to obtain individual toilet rolls 10. Thus, the toilet rolls 10, 10... According to the present invention are manufactured.

"Toilet roll of the first embodiment"
Next, the toilet roll according to the first embodiment of the present invention will be described.
The toilet roll according to the present invention is one in which toilet paper S3 is wound around a paper tube 11, as shown in FIG. The size and the like are not limited, but generally, the width L1 is 100 to 115 mm, the diameter L2 is 100 to 120 mm, the winding length (the total length of the toilet paper) is 18 to 70 m, and the paper tube diameter is 35 to 50 mm. .

  The toilet paper S3 according to the present invention may be a known one, but the water disintegration result in the test method for ease of loosening defined in JIS P 4501 is 100 seconds or less. Normally, if it exceeds 100 seconds, the water disintegration is slow, and there is a possibility that the drain pipe is clogged when discarded in a flush toilet, for example. In the present invention, since it is one of the problems to make it possible to dispose of the paper tube in the flush toilet, it is assumed that the toilet paper S3 can also flow into the flush toilet.

  In order to achieve the above-mentioned water disintegration in the toilet paper S3, it is possible to achieve it by a known method such as adjustment of the beating degree of the raw slurry and non-use of wet paper strength agent.

  On the other hand, in the present invention, as shown in FIG. 4, the paper tube base paper 12 constituting the paper tube 11 is characteristically laminated by laminating a plurality of water-decomposable base papers 22 and 22 with a water-soluble adhesive 25. As a result, the paper tube base paper 12 and further the paper tube 11 itself are made water-decomposable. Further, a water-soluble cleaning agent is carried on any of the water-decomposable base papers 22 and 22 constituting each layer of the paper tube base paper 12. In FIG. 4, (A) illustrates the paper tube base paper 12 composed of two (two layers) water-decomposable base papers 22 and 22, and (B) illustrates three (three-layer) hydrolysable base papers 22 and 22. The paper tube base paper 12 composed of 22 and 22 is illustrated. Note that the number of layers of the water-decomposable base paper 22 and the position where the cleaning agent 50 is carried are not limited to the illustrated example. For example, the cleaning agent 50 may be carried on the portion of the two-ply paper tube base paper 22 facing the water-soluble adhesive 25, or one of the water-decomposable base papers 22, 22 ... constituting each layer. A mode in which the cleaning agent 50 is supported only on the (one layer) hydrolyzable base paper 22 may be employed.

  Here, the water disintegration property of the paper tube 11 as a whole is desirably 100 seconds or less as a result of water disintegration in the test method for ease of loosening defined by JIS P 4501 as with the toilet paper. If it exceeds 100 seconds, it will be unsuitable for flowing into the toilet.

Here, in order to improve the water disintegration property of the paper tube 11 itself, the basis weight of the water disintegratable base paper 22 constituting the paper tube base paper 12 is set to about ²⁰ to 50 g / m ² , and the number of laminated layers is set to about 2 to 4 layers. Is desirable. If it does in this way, when paper tube 11 is thrown into a toilet, it will be separated into each layer quickly, and cleaning agent 50 will elute, and water decomposability and a cleaning effect will become favorable. In addition, about lamination integration of the water-decomposable base paper 22, after applying the water-soluble adhesive 25 to at least one surface of the front and back surfaces of the predetermined number of water-decomposable base paper 22 by various known coating machines and printing machines, May be manufactured by pressurizing with a suitable nip roll or the like. Further, as the water-decomposable base paper 22, a paperboard or crepe paper produced by a known paper machine can be used.

Here, in order to improve the water disintegration property of the paper tube 11, (1) when making the water disintegratable base paper 22 constituting the paper tube base paper 12, the beating degree of the pulp slurry as a raw material is set to be a low beating degree. (2) The water-degradable base paper 22 and the water-soluble adhesive 25 constituting the paper tube base paper 12 are not used with a sizing agent that increases water repellency or a wet paper strength agent that increases paper strength when wet. Or (3) the basis weight of the paper tube base paper 12 as a whole is about 100 to 220 g / m ² , (4) a water-soluble adhesive 25 for laminating and integrating the water-degradable base papers 22; It is desirable that the paste 30 for adhering the paper tube base papers has high water solubility such as starch paste and PVA (polyvinyl alcohol).

In addition, about the beating degree of the raw material of the said water-degradable base paper 22, it is desirable to set it as about CSF (Canadian Freeness) of about 500-600. If the CSF exceeds 600, the paper tube 11 may have insufficient strength, and if it is less than 500, the water disintegration will deteriorate. If the basis weight of the paper tube 11 as a whole is less than 100 g / m ² , the strength at the time of winding the toilet paper may not be ensured at the time of production, and if it exceeds 220 g / m ² , the water disintegration will be extremely deteriorated. To do. About the usage-amount of a sizing agent and a wet paper strength agent, it can determine suitably in relation to the said CSF and basic weight.

As for the water-soluble adhesive 25, to secure the water-degradable, it is desirable to 0.1g / m ² ~5.0g / m ² approximately deposition volume. Within this range, the water-soluble adhesive itself exhibits sufficient water solubility, and when the paper tube 11 is put into the toilet, it is quickly decomposed into the paper tube base paper 12 constituting the paper tube 11 and the paper tube 11. The water disintegration property of the resin becomes good.

Also, the glue 30 to adhere the paper tube sheet 12 to each other also, in order to improving the water-degradable, it is desirable to 0.1g / m ² ~5.0g / m ² approximately deposition volume.

  Here, in order to improve the water-disintegration property of the paper tube 11, the paper tube base paper 12 has a large number of holes, and the user cuts the paper tube 11 finely after using the toilet paper S3 by giving a perforation line. And it is good also as an aspect which can be poured into a toilet.

  On the other hand, in the present invention, the cleaning agent 50 is supported on the water-decomposable base paper 22 with respect to the dry paper in the step after the dry paper formation in the paper machine or the base paper manufactured by the paper machine. What is necessary is just to provide a solution or cleaning agent slurry by an application | coating means. Examples of the applying means include various coating machines such as a size press coater, a gate roll coater, a bill blade coater, and a curtain coater, a printing machine such as a flexographic printing machine, a gravure printing machine, and an inkjet printing machine, and a spray coating apparatus.

On the other hand, in the present invention, the cleaning agent 50 is contained in the adhesive 25 that bonds the hydrolyzable base papers 22 to each other . In this case, after applying the water-soluble adhesive 25 to the water-degradable base paper 22, the powdery cleaning agent 50 is sprayed and fixed to the water-soluble adhesive 25 to such an extent that the adhesive force does not excessively decrease. You may try. In this way, a relatively large amount of the cleaning agent 50 can be carried on the paper tube 11, so that the elution rate of the cleaning agent when the paper tube 11 is put in the toilet can be increased, and the cleaning effect is also high. It becomes.

  Here, as the cleaning agent 50, a known water-soluble cleaning agent used for cleaning use such as a known toilet bowl and toilet seat and wiping use can be used. Preferred are cationic surfactants, anionic surfactants, nonionic surfactants, and amphoteric surfactants, which are highly stable and safe and have a high cleaning effect.

  When the cleaning agent 50 is carried on the plurality of water-decomposable base papers 22 constituting the paper tube base paper 12, the types of the cleaning agents 50 carried on the water-decomposable base papers 22 are not necessarily the same. A plurality of types of cleaning agents can be used as appropriate. In addition, when a water-soluble adhesive that bonds water-decomposable base papers contains a cleaning agent, the type of the adhesive to be carried on the water-decomposable base paper may be different from the cleaning agent that is included in the water-soluble adhesive. Good. The same applies to the case where a cleaning agent is contained in the glue for bonding the paper tube base papers to form the paper tube.

  Further, the detergent may contain a vegetable acid such as citric acid and an alkali agent such as sodium bicarbonate. By containing citric acid or baking soda, it is possible to improve the removal of scales and urine stones attached to the toilet bowl. Further, only these acids and alkali agents may be used as the cleaning agent 50.

  Further, the cleaning agent may contain a foaming component that foams by reaction with a large amount of water. The improvement of the cleaning property by the foaming effect and the decomposability of the paper tube 11 are enhanced.

  On the other hand, the carrying amount of the cleaning agent on the water-degradable base paper in the present invention is not particularly limited, but it is preferable that the carrying amount of the entire paper tube is 0.05 g or more. If it is less than 0.05 g, the cleaning effect may not be obtained. Preferably, it is 0.5 to 5.0 g.

  In the toilet roll 10 of the above embodiment, the toilet tube can be washed by putting the paper tube 11 remaining after the toilet paper S3 is completely used up into the toilet.

"Toilet roll of the second embodiment"
Next, a toilet roll according to a second embodiment of the present invention will be described.
In the toilet roll of the first embodiment, the present embodiment is one in which a cleaning agent is carried on the outer surface (outer peripheral surface and inner peripheral surface) of the paper tube.

  In this embodiment, when the paper tube base paper 12 is manufactured, a cleaning agent is applied to one or both sides of the water-decomposable base paper 22 constituting the surface layer so that the coated surface becomes the surface of the paper tube base paper 12. So that they can be laminated and integrated. Moreover, you may apply | coat the cleaning agent 50 to front and back after paper tube base paper formation.

  In this embodiment, since the cleaning agent is carried on the outer surface of the paper tube, the cleaning agent elutes instantly when it is put into the toilet, so that not only the toilet piping but also the trap part which is a water pool portion can be effectively cleaned. Can do.

  In this embodiment, a water-soluble cleaning agent may be supported only on the outer peripheral surface around which the toilet paper S3 of the paper tube 11 is wound. In this case, as described in the column of the operational effect, there is no risk of the cleaning agent detachment due to sliding with the support portion of the paper holder when it is carried on the inner peripheral surface of the paper tube.
