Description

  The present invention relates to a toilet roll core and a toilet roll.

  Conventionally, a toilet roll in which toilet paper is wound around a paper tube is known. The paper tube is generally called a “core”.

  In the new toilet roll, the portion close to the outermost end is lightly glued to the surface under one turn of the winding so that the toilet paper is not naturally rewound. And the length which is pinched and lifted when the user peels off the said gluing is ensured at the end of toilet paper.

  Toilet rolls are usually attached to a holder fixed to the wall in the toilet. As a holder, a holder having a shaft rod extending in the horizontal direction and extrapolating a toilet roll core is popular.

None

  When the toilet roll has been used up to the end, replace the core remaining in the holder with a new toilet roll. At this time, in order to attach the toilet roll so that the toilet paper can be pulled out in the direction you prefer, carefully observe the surroundings of the glued part, remove the glue, You have to figure out the direction.

  However, since the toilet paper is thin and soft, the situation may not be well understood even when the periphery of the glued portion is observed, or it may not be peeled off well even if the glue is removed. If you make a mistake in the orientation of the holder, you will be able to step on the ground in a small toilet.

  Therefore, the present invention provides a toilet roll core for easily attaching the toilet roll to the holder so that the toilet paper can be pulled out in a desired direction, and a toilet roll including the core. Objective.

  The core of the toilet roll of the present invention is provided with an identifier on the inner surface for specifying one of the circumferential directions. The toilet roll provided with this core can align the direction specified by the identifier and the direction in which the toilet paper is wound around this core. In this case, when the toilet roll is attached to the holder, the toilet roll can be easily attached to the holder so that the direction in which the toilet paper is drawn becomes the preferred orientation by checking the direction specified by the identifier.

  A plurality of the identifiers may be provided in the axial direction. It is desirable that the identifiers be provided at both ends of the core from the viewpoint of ease of visual recognition. However, the long core, which is continuously made from a base paper by a spiral machine, is cut to the size of the toilet roll. For the convenience of manufacturing the core to be separated, it is not easy and practical for the identifiers to be located only at both ends of the core. Therefore, the fact that a plurality of identifiers are provided in the axial direction means that pipes are manufactured so that the probability that the identifiers are located at both ends of the separated cores is high regardless of where the long core is cut. This means that the core manufactured in this way is convenient for the user of the toilet roll including the core to easily recognize the identifier.

  Moreover, it is preferable that a plurality of the identifiers are provided in the circumferential direction. If there is only one identifier in the circumferential direction, the identifier may not be located on the inner surface that happens to be visible when looking at the core. Needs to be turned around the axis. In contrast, when a plurality of identifiers are provided in the circumferential direction, there is a high probability that the identifier can be visually recognized without rotating the core in the circumferential direction, and only one identifier is provided in the circumferential direction. Compared with the case, the visibility of the identifier is improved.

  Moreover, it is preferable that a plurality of the identifiers are provided so as to follow a spiral centering on the axis. According to this, when the core is continuously manufactured by the spiral machine, it is only necessary to provide the identifier as a simple repeating pattern with respect to the base paper, and therefore it is easy to provide the identifier.

  The identifier is preferably composed of at least one selected from the group consisting of characters, figures, symbols, and irregularities. According to this, the direction specified by the identifier can be easily expressed.

  The identifier is preferably provided by printing, printing, imprinting or stamping. These means are more suitable for mass production than other display methods.

  The core of the present invention preferably has an axial length of 112 mm to 116 mm, or 2.5 m to 3.5 m.

  The present invention also relates to a method for manufacturing a toilet roll core, wherein one of the circumferential directions of the core is specified on a surface that is an inner surface when pipes are manufactured among the surfaces of the base paper constituting the core. There is provided a method for manufacturing a toilet roll core, comprising a step of providing a plurality of identifiers in the length direction of a base paper and a step of forming the core by pipe-making the base paper. According to this, it is possible to manufacture a core with a high probability that an identifier is located at both ends of the separated core wherever the manufactured long core is cut.

  The present invention also includes the above-described core and toilet paper wound around the core, and the toilet paper is provided with a toilet roll wound in the direction specified by the identifier with the outer surface of the core as a base end. To do. In this toilet roll, the direction specified by the identifier matches the direction in which the toilet paper is drawn after the toilet roll is attached to the holder. Therefore, by grasping the direction specified by the identifier, the toilet roll can be easily attached to the holder so that the toilet paper can be pulled out in the direction desired by the user.

  Further, the present invention is a paper tube in which an identifier for specifying any one direction in the circumferential direction is provided on the inner surface, and the identifier is a spiral in the axial direction of the paper tube or around the axis. A plurality of paper tubes provided by printing, printing, imprinting or engraving are provided.

  ADVANTAGE OF THE INVENTION According to this invention, the toilet roll core for enabling a toilet roll to be easily attached to a holder so that the drawer direction of toilet paper may turn into a favorite liking, and a toilet roll provided with the said core are provided. .

[Definition of terms]
Terms used in this specification are defined as follows.
-“Toilet roll” means “toilet roll core” wound with “toilet paper”.
-“Toilet roll core” is also simply called “core”. “Core” refers to both of a state adjusted to an arbitrary length after pipe making and a state adjusted to the width of a toilet roll as a product that reaches a consumer's hand. Shall.
“Direction” refers to both directions in which the virtual line extends from an arbitrary point on the virtual line. On the other hand, “direction” indicates one of them.

[Toilet roll core]
As shown in FIG. 1 (a), a toilet roll core (hereinafter simply referred to as "core") 1 is a paper tube formed in a hollow cylindrical shape.

  The core 1 is continuously formed by, for example, winding a base paper spirally around a shaft rod of a spiral machine, and the core 1 is cut into an arbitrary length and manufactured. For example, after being cut into a length of about 3 m, toilet paper is wound around this. Then, the core 1 and the toilet paper are simultaneously cut into a length of 114 mm ± 2 mm, and become a separated toilet roll as a product that reaches the consumer. “114 mm ± 2 mm” is a width value of the toilet roll defined in JIS P 4501 (1993).

  The length of the core 1 in the axial direction is arbitrary, but considering the manufacturing process of the core 1 and the toilet roll described above, 2.5 m to 3.5 m is preferable, and 2.8 m to 3.2 m is more preferable. Considering the width of the toilet roll as a product reaching the consumer, the length of the core 1 in the axial direction is preferably 112 mm to 116 mm. The inner diameter of the core 1 is preferably 4.0 mm to 4.5 mm.

  FIG. 1B is a development view in which the core 1 of FIG. 1A is cut open along the axial direction, and shows the state of the inner side surface of the core 1. As shown in FIG. 1 (b), the core 1 is provided with an identifier 3 for specifying one of the circumferential directions of the core 1 on the inner surface thereof. Here, an arrow for specifying the downward direction on the paper surface is printed.

  A plurality of the identifiers 3 are printed so as to repeat in the axial direction and the circumferential direction of the core 1. In the axial direction, printing is preferably performed at intervals of 5 mm to 20 mm. In the circumferential direction, it is preferably printed at a position of 3 to 8 positions. In these cases, the identifier 3 is easily visible when the inner surface of the core 1 is viewed from an oblique direction of the core 1. FIG. 1A shows the state of peeping, and it can be seen that the direction of one direction of the circumferential direction is specified by the arrow as the identifier 3.

  Arranging the identifiers 3 at the positions printed repeatedly as described above is achieved by printing the identifiers 3 on the base paper in advance in consideration of the spiral angle in the manufacture of the core 1 using a spiral machine. can do. That is, as a manufacturing method of the core 1, a step of providing a plurality of identifiers 3 in the length direction of the base paper on the surface of the base paper constituting the core 1 which becomes the inner surface when the pipe is manufactured is performed.

  The identifier 3 is preferably composed of at least one selected from the group consisting of characters, figures, symbols, and irregularities. Various aspects of identifier 3 are shown in FIG. In FIG. 2, a total of 28 types of identifiers of 7 types in the vertical direction and 4 types in the horizontal direction are drawn so as to specify the downward direction in the drawing. According to these aspects, the direction specified by the identifier can be easily expressed. In particular, a figure including an arrow is preferable because of its high direction discrimination.

  As a method for displaying the identifier 3 on the inner surface of the core 1, printing is suitable for mass production. However, in addition to printing, engraving, branding, printing, stamping, sticker sticking, and the like are possible. As described above, the identifier 3 is provided at the stage of the base paper before the core 1 is manufactured. At this time, from the viewpoint of manufacturing cost and labor, it is preferably provided directly on the base paper without interposing other layers such as a film layer and a paper layer. The identifier 3 may have an arbitrary color.

  As described above, since the core 1 is provided with the identifier 3 for specifying one of the circumferential directions on the inner surface, the toilet roll provided with the core 1 has the direction specified by the identifier 3 and this The drawing direction of the toilet paper wound around the core 1 can be aligned. In this case, when the toilet roll is attached to the holder, by confirming the direction specified by the identifier 3, the toilet roll can be easily attached to the holder so that the direction of drawing out the toilet paper is a preferred direction. Moreover, since the shape of the core 1 is a cylindrical shape that does not have irregularities that become a special obstacle when the core 1 is extrapolated to the shaft rod of the holder, it is extrapolated in either direction with respect to the shaft rod of the holder. be able to. Further, according to the above-described core manufacturing method, a core with a high probability that the identifier 3 is located at both ends of the core 1 that is separated into pieces is cut regardless of where the manufactured long core is cut. Can do.

[Toilet roll]
FIG. 3 shows a toilet roll 10 with a core 1. The toilet roll 10 includes a core 1 and toilet paper 5 wound around the core 1. Here, the toilet paper 5 is wound in a direction (counterclockwise in FIG. 3) specified by the identifier 3 with the outer surface of the core 1 as a base end.

  In the toilet roll 10, the direction specified by the identifier 3 matches the direction in which the toilet paper 5 is pulled out after the toilet roll 10 is attached to the holder (that is, the direction in which the core 1 rotates when pulled out). . Therefore, by grasping the direction specified by the identifier 3, the toilet roll can be easily attached so that the direction in which the toilet paper 5 is pulled out is the direction desired by the user.

  Since the toilet paper 5 is thin and soft, conventionally, when handling a new toilet roll, the situation is not well understood by observing the periphery of the glued portion (51 in FIG. 3) on the outermost surface. Even if the edge (52 in FIG. 3) is pinched and the glue is peeled off, it does not peel off well, which is annoying. In the toilet roll 10 of the present embodiment, such annoying thought is not caused by the identifier 3.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to the said embodiment, It can implement in another various aspect. For example, a plurality of identifiers may be provided along a spiral centered on the axis of the core. In this case, when the core is continuously produced by the spiral machine, it is only necessary to provide the identifier as a simple repetitive pattern on the base paper. An example of this aspect is shown in FIG. FIG. 4 shows a developed view in which the core 1A having a length of 114 mm is cut along the axial direction. Here, the code | symbol 7 has shown the boundary of the base paper wound spirally.

  Further, the identifier is not limited to the toilet roll core, and can be provided for all the paper tubes. Providing an identifier is useful, for example, for a film tube, wrap paper tube, tape paper tube, or the like that needs to identify the winding direction of a wound object.

  The present invention can be used in situations where toilet rolls are used.
