[Industrial applications]

 This invention is a toilet that has a large hole of a predetermined size in the center, for example, a large diameter hole of 3.8 cm in diameter. It is related to paper rolls.

[0002]

[Prior art]

 As a conventional ordinary toilet paper roll, it is loosely wrapped around a paper tube core, which is a core having a diameter of about 3.8 cm, and the outer diameter of the toilet paper roll is 11. even if the length of the toilet paper is 65 m. There is about 5 cm. Further, as conventional coreless toilet paper rolls, there are, for example, Japanese Patent No. 1,022,189 (Japanese Patent Publication No. 55-11100) and Utility Model Registration No. 1,366,748 (Japanese Utility Model Publication No. 54-43963). There is a coreless toilet paper roll in which the toilet paper is first wound around the core loosely, then tightly wound, and then the core is removed after winding.

[0003]

[Problems to be solved by the device]

 The former ordinary toilet paper roll of the former requires a paper tube core, which increases the cost due to the need for the paper tube core at the time of production, and it is loose for the length of the toilet paper. There is a problem that it is bulky because it is wrapped, and the paper core that is the core remains after using all the toilet paper at home, office, company, etc. There was a problem that it did not happen. In the latter conventional coreless toilet paper roll, as shown in FIG. 5, after the core is removed, the central very fine pores 12 formed in the toilet paper roll 13 are initially spaceed by the loosely wound toilet paper 11 '. Since the shape is such that the central very small pore 12 is naturally closed, the perfect very small pore 12 is not formed at the center of the toilet paper roll 13, and at the time of use, one end is sharp and the other end is contracted by a spring or the like. A free dedicated thin core rod 14 (about 1 cm in diameter) must be inserted into this incomplete polar pore 12 from the pointed end, and this core rod 14 must be locked to the toilet paper holder for use. Therefore, the ordinary thick mounting support rod (diameter of about 2.5 cm) that is attached to general households cannot be used, and the specially shaped core rod 14 is required. However, there is a problem that the cost is increased by the amount of the required amount, and since the specially shaped core rod 14 remains after using the toilet paper 11, one core rod is included for each bag containing several rolls. There was a problem that the core rod 14 had to be discarded every time several rolls were used because it was put in.

The present invention solves the above-mentioned problems of these conventional toilet paper rolls, lowers the cost, reduces the bulk (volume) for the length of the toilet paper, and Do not always lose its shape, always be easily attached to a conventional holder, use the toilet paper in the cylindrical part at the center of the roll, leave nothing after use, have a large hole of the specified size in the center It has a good roll-like shape, it is a good toilet paper roll, it can be used up to the final toilet paper when it is used, and it does not cause unnatural and ugly wrinkles on the toilet paper. That the toilet paper rolls of the toilet paper roll do not adhere firmly, and It is intended to be used as illette paper.

[0005]

[Means for Solving the Problems]

 The toilet paper roll of the present invention is a toilet paper roll from the point of 30 cm to 70 cm from the end of the rolled roll of the toilet paper, and at the both ends in the width direction of the toilet paper, 2 to 3 times the amount of the adhesive aqueous solution or water is used. After the toilet paper is sprayed on the paper, the toilet paper is wrapped tightly around the winding shaft with the same outer diameter as the paper tube core and wound tightly in a roll on the outside of the winding shaft. Only the toilet paper that is removed after forming and wound tightly has a large hole of a predetermined size in the center of the toilet paper, and the toilet paper cylinder is temporarily attached to the toilet paper and formed into a roll shape.

[0006]

[Action]

 The toilet paper roll of the present invention has a predetermined distance from the end of the roll of the toilet paper, and the two ends of the toilet paper in the width direction are provided with adhesive aqueous solution or water in an amount 2 to 3 times that of the central portion. After spraying, the toilet paper has a toilet paper that is wound tightly around the same axis as the paper tube core and rolled tightly around the outside of this axis. Only the toilet paper that was pulled out after molding and wound tightly has a large hole of a specified size in the center, and both ends of the toilet paper in the width direction are temporarily fastened more strongly than the center. Since the tubular part of the toilet paper was molded and retained in a roll shape, when the toilet paper is tightly wound around the reel, Since there is no aqueous solution of adhesive or water in the roll, there is no risk that the lengthwise end of the toilet paper will stick to the reel, and water sprayed on the toilet paper will not be wrapped in the toilet paper. Since it penetrates and spreads inside and outside of the toilet paper, many unnatural and ugly `` wrinkles '' do not occur on the toilet paper where the water is sprayed, and the toilet paper does not stick firmly. The shape of the toilet paper roll, which tends to lose its shape, is stronger than the center of the toilet paper in the widthwise direction. The cost is low because the paper core is not used at the time of production and the special shape of the core rod is not used because it is attached to the normal holder at the time of use, and the toilet paper cylinder is molded inside the roll. It is easy to attach to a normal holder, and long toilet paper can be wrapped with the same volume (bulk) as it is tightly wrapped. Further, since the adhesive paper solution or water is sprayed to mold the tubular part of the toilet paper, the toilet paper in the tubular part of the toilet paper is in a temporarily attached state. It can be pulled out further and used, and the paper tube core and specially shaped core rod do not remain after use.

【Example】

 Next, one embodiment of the toilet paper roll of the present invention will be described with reference to the drawings. The tightly wound toilet paper roll 4 has a hole in the center thereof having a size that can be locked in a normal holder, for example, a large hole 2 having a predetermined size of about 3.8 cm in diameter. It has a tubular portion 3 of toilet paper which is worn and is temporarily attached to both ends in the width direction more strongly than the central portion. The tubular portion 3 is a portion 1 ″ about 45 cm from the end 1 ′ of the toilet paper 1 at the beginning of winding, and at both ends of the toilet paper 1 in the width direction, 2 parts of the low-concentration adhesive aqueous solution sprayed to the center portion. By spraying 0.5 times the amount over a length of about 50 cm and rolling the toilet paper from its end 1 ', the aqueous adhesive solution is permeated and diffused into the inside and outside of the rolled toilet paper, and the width of the toilet paper is equal. Both ends in the direction are temporarily fastened more strongly than the central part.Toilet paper 1 is tightly wrapped around tubular toilet part 3 having this large hole 2 and both ends strongly fastened, and only toilet paper 1 is It is a toilet paper roll 4 having an outer diameter of about 11.5 cm, which is shaped like a perforated roll.

As a method of making the toilet paper roll 4 of this embodiment, as shown in FIG. 3, two parallel rolls of a retractable metal winding shaft 5 having an outer diameter substantially the same as that of the paper tube core are used. 6 and 6, a pressure roll (riding roll) 7 is provided on the winding shaft 5, and a spray nozzle 8 is further provided toward the winding shaft 5. By supplying the toilet paper 1 to the winding shaft 5, the winding shaft 5 is rotated along with the rotation of the rolls 6 and 6, and the toilet paper 1 is tightly wrapped around the outer circumference of the winding shaft 5 while being pressed by the pressure roll 7. Be kicked. In this tight winding, as shown in FIG. 2, both ends 1/4 of the width of the toilet paper 1 start from a point 1 ″ about 45 cm from the beginning 1 ′ of the toilet paper 1. (Lower to the center is 1/2) 2.5 times the concentration of the center is about 0.5% and low concentration polyvinyl alcohol (PVA) aqueous solution is sprayed from the spray nozzle 8 onto the toilet paper 1 over a length of about 50 cm. The toilet paper 1 is sprayed with the sprayed PVA aqueous solution as described above so that the PVA aqueous solution permeates and diffuses inside and outside the toilet paper, and the toilet paper 1 is a toilet paper tube in which both ends in the width direction are temporarily attached to the toilet paper stronger than the center. The shaped part 3 is formed.As with a normal toilet paper roll, the outer diameter is tightly wound to about 11.5 cm, and then the winding is stopped. Allow at least 7 minutes for the temporary toilet paper tubular part 3 to keep its shape, because it is not possible to separate the tightly wound toilet paper roll 3 and winding shaft 5 from each other. 3. The outer diameter of the shaft 5 is reduced as shown by the phantom line in Fig. 4, and then the toilet paper roll 4 wound tightly around the winding shaft 5 with the reduced outer diameter is removed. A toilet paper cylinder 3 having a large hole of 8 cm is formed and a roll-shaped toilet paper roll 4 is produced.The toilet paper roll 4 of this example has an outer diameter of about 11.5 cm, which is the same as the conventional one. Although the outer diameter is almost the same as that of the toilet paper, the length of the toilet paper is about 130 m, so it is about twice as long as the conventional one with the same outer diameter of about 65 m. It is not bulky because it can be made to have almost the same volume, and it can be used for a long time, and it takes about half the time to replace the toilet paper roll with the holder. Attach 3 to the holder and pull out the toilet paper in the tubular part 3 of the toilet paper from the holder to use.

As a method of manufacturing the toilet paper roll of this embodiment, an aqueous solution of an adhesive agent is applied at a position about 45 cm from the beginning end of the toilet paper roll, and 2.5 times as much as the central portion at both ends in the width direction. I explained that spraying the toilet paper onto the toilet paper, but if it is too close to the beginning of the toilet paper, the toilet paper may stick to the reel, and if it is far from the beginning of the toilet paper, the toilet paper As a result of the test, it is better to start from about 30 cm to about 70 cm from the beginning end of the roll of the paper because the end is not temporarily attached. Further, the length of spraying the adhesive aqueous solution on the toilet paper has been described as being sprayed over a length of about 50 cm in this example, but similar test results show that the length is about 50 cm to about 100 cm, and both ends in the width direction are good. If the amount of the adhesive aqueous solution is too small, the temporary adhesion force will be small and the ends will be easily deformed.If the amount of the adhesive aqueous solution is too large at both ends in the width direction, the adhesive will be too rigid and the tubular part Since the toilet paper in this case cannot be rewound smoothly, the result of the test is that it is about 2 to 3 times the center of the toilet paper in the width direction. Then, instead of the aqueous solution of the adhesive, water may be used as well. Further, the aqueous solution of the adhesive to be sprayed has the property of being redissolved in carboxymethyl cellulose (CMC) or water having a concentration of about 0.5% in addition to the PVA aqueous solution having a concentration of about 0.5%, and having a concentration of 0.05%. To about 0.01% acrylic adhesive is preferable.

[Effect of device]

 The toilet paper roll of the present invention is located at a position 30 cm to 70 cm from the beginning of the toilet paper roll, and the width of both ends of the toilet paper is 2 to 3 times that of the central portion of the adhesive solution or After spraying water, the toilet paper has a toilet paper that is wound tightly around the winding shaft having the same outer diameter as the paper tube core and is wound tightly around the winding shaft in a roll shape. Only the toilet paper that has been pulled out after winding and wound tightly has a large hole of a specified size in the center, and the toilet paper is temporarily attached, and both ends in the width direction are temporarily attached more strongly than the center. Since the roll-shaped part was formed by shaping the shaped part, the adhesive water solution or water was placed on the toilet paper at the beginning of winding when the towel paper was tightly wound around the winding shaft. Kuo with longitudinal end of the fry in toilet paper tension in the winding shaft it at all, a good toilet paper rolls. And since there is no possibility of sticking to the reel, the final toilet paper will not be damaged, and even the final toilet paper can be used at the time of use, and water etc. sprayed on the toilet paper Since it penetrates and spreads inside and outside the toilet paper wrapped around the toilet paper, it has the effect of preventing unnatural and ugly "wrinkles" from occurring on the toilet paper in the area where water is sprayed. It has the effect that the lett paper comrades do not stick together firmly. In addition, the cost can be reduced by not using the toilet paper roll paper tube core and the special shape core rod that is attached to the ordinary holder, and since it is wound tightly, it has the same volume and a long toilet. Since it can be wrapped with paper, it is not bulky, and when used, long toilet paper rolls can be used for a long period of time, and the frequency of replacement can be reduced. Furthermore, the shape of a toilet paper roll formed by forming a tubular portion of the toilet paper, in which both ends in the width direction are temporarily adhered to the center of the roll more strongly than the center, allows good shape retention, and the inside of the roll is always deformed. Instead, you can always use it by simply inserting the thick support rod of the conventional holder into the large hole of the toilet paper roll and always easily attaching it to the conventional holder. All toilet paper can be used by pulling out the toilet paper of the part from the holder, and since there is nothing left after use, discarding the paper core from the holder and discarding the paper core as in the past The effect is that it does not require time and effort.
