Description

[Detailed Description of the Invention] Industrial Application This invention has a large circular hole with a predetermined size, for example, a large circular hole with a diameter of about 3.8 cm, at the center of the beginning of winding, and toilet paper rolls are rolled. A temporary adhesive cylinder core made of the hard temporary adhesive toilet paper itself is provided, and the temporary adhesive cylinder core of the toilet paper is continuous with the temporary adhesive cylinder core of the toilet paper. The toilet paper relates to a tightly wound toilet paper roll.

Conventional technology As a conventional ordinary toilet paper roll, it is loosely wound around a paper tube core that is a core with a diameter of about 3.8 cm.
The length of loosely wound toilet paper is about 65 m, and the outer diameter of the toilet paper roll is about 11.5 cm.

Problems to be Solved by the Invention In this conventional extremely ordinary toilet paper roll, since a paper tube core is required, it is necessary to prepare the paper tube core in advance and the cost is increased by the amount of the paper tube core. Along with the problems, there are problems that it takes time to supply the paper tube core to the winding machine, and there is a problem that the paper tube core cannot be used as toilet paper. Also, after using all the toilet paper at home, office, company, etc., the paper core that is the core remains, so this paper core cannot be flushed to the flush toilet and must be discarded to another place. There was a problem.

This invention solves the above-mentioned problems that conventional toilet paper rolls have, and does not use a paper tube core, but uses all toilet paper rolls including a temporary adhesive tube core made of toilet paper as toilet paper. Toilet paper roll does not lose its shape, temporary adhesive tube core made of toilet paper can be easily made when winding the toilet paper to reduce the cost, and despite having a large circular hole in the center, it is circular. The purpose is to maintain the shape of the hole well, to attach it to a thick supporting rod of an ordinary holder, and to reduce the bulk (volume) for the length of the toilet paper.

Means for Solving the Problems A toilet paper roll according to the present invention is a toilet paper roll in which a predetermined amount of toilet paper is tightly wound around a winding start portion of a toilet paper roll having a large circular hole of a predetermined size in the center. A temporary sticking tube core made of roll-shaped toilet paper itself is provided, which is temporarily adhered to each other by an adhesive that can be temporarily adhered to each other so that the toilet paper can be pulled out at the time of use without being rolled up. A predetermined amount of toilet paper is provided around the outer circumference of the cylinder core, around which the toilet paper, which is continuous with the temporary toilet paper for temporary adhesion of the toilet paper, is tightly wound.

The toilet paper roll of the present invention has a large amount of a circular hole of a predetermined size at the center, and a predetermined amount of the toilet paper is tightly wound around the beginning of the roll of the toilet paper roll, and the toilet paper rolls can be temporarily bonded together. A temporary adhesive core made of roll-shaped toilet paper itself that is temporarily adhered to each other by a chemical agent so that the toilet paper can be pulled out at the time of use without being rolled up, and is provided on the outer circumference of the temporary adhesive core of the toilet paper. A certain amount of toilet paper tightly wrapped with continuous toilet paper that is a temporary core of toilet paper
Since it is installed, the temporary adhesive tube core made of toilet paper at the time of production is easy to make when tightly winding the toilet paper and the paper tube core is not used, so the cost of the toilet paper roll is low and a large circular hole at the center The provisional adhesive core made of toilet paper does not deform, and the provisional adhesive core made of toilet paper does not lose its shape because it is firmly and well-shaped. The large circular hole in the shape is well retained. Also, since a large circular hole is provided in the center, it can be attached to an ordinary holder, and a long length of toilet paper can be wound with the same volume (bulk) as it is tightly wound. And since it is possible to use a long toilet paper for a long time for a long time, the frequency of replacement work is reduced, and a toilet paper roll with temporary adhesion of a temporary core made of toilet paper is used as a toilet paper roll. Since all of the above are used and the tube core for temporary adhesion of toilet paper does not remain after use, it is not necessary to dispose of the paper tube core in another place as in the conventional case.

Embodiment Next, one embodiment of the toilet paper roll of the present invention will be described with reference to the drawings.

The toilet paper roll 4 is provided with a temporary bonding cylinder core 3 made of the toilet paper itself having a predetermined large circular hole which can be locked in a usual holder, for example, a large circular hole 2 having a diameter of about 3.8 cm, at the center of the roll start portion. The toilet paper 1 is tightly wound around the temporary core 3 made of this toilet paper, and the wound toilet paper 1 is temporarily adhered in a roll-like rigid state.

A predetermined amount of toilet paper tightly wound around the outer periphery of the temporary adhesive core 3 made of this toilet paper, which is continuous with the toilet paper 1 constituting the temporary adhesive core 3. Paper 1
Toilet paper roll 4 with an outer diameter of about 11.5 cm
Is.

The temporary-bonded cylinder core 3 is made of a roll-shaped toilet paper itself which retains a large circular hole 2 of a predetermined size at the center thereof and does not lose its shape and can be pulled out when used.

As a method of manufacturing the toilet paper roll 4 of this embodiment, as shown in FIG. 2 and FIG. 3, a hard metal core 5 having an outer diameter that can be contracted is provided on two parallel rolls 6, 6. At the same time, a pressure roll 7 is provided on the hard core 5, and a spray nozzle 8 is further provided toward the core 5.

By supplying the toilet paper 1 to the winding core 5, the winding core 5 is rotated along with the rotation of the rolls 6, 6, and the toilet paper 1 is tightly wound around the outer circumference of the winding core 5 while being pressed by the pressure roll 7. To be

When the toilet paper 1 is wrapped tightly, an aqueous solution having a polyvinyl alcohol (PVA) concentration of about 0.5%, which is an adhesive that allows the toilet papers to temporarily adhere to each other at the beginning of the toilet paper 1, is sprayed from the spray nozzle 8 onto the toilet paper 1 by about 50 cm. Spray little by little over the length of. A small amount of sprayed low-concentration PVA aqueous solution and the toilet paper 1 are tightly wrapped around the toilet paper 1 so that the toilet paper 1 is temporarily adhered to each other in a roll-like rigid state, and the temporary adhesive core made of the toilet paper is used. 3 is molded.

Furthermore, the toilet paper 1 of the temporary adhesive bonding core 3 is continuous to the outer periphery of the temporary bonding cylindrical core 3 made of the rigidly temporarily bonded toilet paper formed at the beginning of the roll of the toilet paper roll 4. The toilet paper 1 is wound into a roll.

In addition, if necessary, another tension roll may be provided at the time of this winding and the toilet paper may be wound while applying a required tension.

After the toilet paper is tightly wound to the outer diameter of about 11.5 cm and the toilet paper outer layer portion 1'is formed,
Stop winding. As it is, a toilet paper roll 4 made up of a temporary adhesive cylinder core 3 made of toilet paper temporarily bonded in a roll state and a toilet paper roll 1 tightly wound in a roll shape around the outer periphery of the temporary adhesive cylinder core 3 Since the hard core 5 is harder to remove than the hard core 5, the outer diameter of the hard core 5 is reduced as shown by the phantom line in FIG. 3 to facilitate the removal, and then the wound toilet paper roll 4 is removed from the core 5 and the toilet paper is removed. Only the roll 4 has a large circular hole of about 3.8 cm in the center thereof, and a toypaper roll 4 is formed in a roll shape.

In addition, the temporary adhesion aqueous solution sprayed as an adhesive capable of temporarily adhering toilet paper to each other is methylcellulose (M) having a concentration of about 0.5% to about 1% in addition to the PVA aqueous solution.
C) and has the property of being redissolved in water, and the concentration is approximately 0.05%
It goes without saying that the toilet paper may be temporarily adhered to each other with about 0.1% acrylic aqueous solution.

Effect of the Invention The toilet paper roll of the present invention is such that the toilet paper is tightly wound around the beginning of the roll of the toilet paper roll and the toilet paper rolls are temporarily and temporarily adhered in a roll shape, and the toilet paper roll is fixed at the center of the beginning of the roll. A temporary adhesive tube core made of a toilet paper roll having a large circular hole is provided, and a toilet paper continuous with the temporary adhesive tube core toilet paper is provided on the outer periphery of the temporary adhesive tube core. Since a certain amount of tightly wrapped toilet paper was provided,
Not only use all of the toilet paper roll, that is, the toilet paper wound around the outer periphery of the temporary adhesive core made of toilet paper as usual, but also temporarily use it as a temporary adhesive core made of toilet paper. It is possible to use the entire toilet paper roll as the toilet paper by pulling out the bonded tubular toilet paper by hand to form the sheet-shaped toilet paper and then using it as the toilet paper.

In this way, because the tube core that is temporarily and temporarily bonded during manufacturing is easily made when the toilet paper is tightly wrapped, the toilet paper with this temporarily bonded tube core and the toilet paper on the outer periphery of this temporarily bonded tube core are Therefore, the cost of the toilet paper roll can be reduced because the toilet paper roll can be easily made by continuously winding the toilet paper around the outer periphery of the temporary core of the temporary attachment of the toilet paper roll.
In addition, since the rigid temporary adhesive cylinder core made of toilet paper acts as a strong temporary core, it has the effect that the inside of the toilet paper roll does not always lose its shape, and the large circular hole provided at the center of the toilet paper roll is well maintained. Since the outer shape of the toilet paper roll is provided on the outer circumference of the temporary core of the temporary toilet paper roll, the entire toilet paper roll is well shaped like a roll and does not lose its shape.

And since the toilet paper roll is tightly wrapped around the temporary adhesive tube core made of toilet paper and the outer layer of the toilet paper, a long toilet paper is wrapped with the same volume, so it is not bulky for storage. In addition to being effective, there is an effect that a long toilet paper can be used for a long time despite its bulkiness, and an effect that it is possible to reduce the frequency of replacement work.

Furthermore, it is possible to insert the thick supporting rod of the ordinary holder into the large circular hole of the toilet paper roll and attach it to the ordinary holder for use, and to use the entire toilet paper roll (the temporary adhesive core made of toilet paper is (Including everything) can be used as toilet paper, so there is no need to throw away the paper tube core (paper tube) to another place as in the conventional case.
