Pop to It is possible to adopt the up method.

  As mentioned above, although concretely demonstrated based on embodiment which concerns on this invention, this invention is not limited to the said embodiment, It can change in the range which does not deviate from the summary.

(Second manufacturing method)
For example, in the example shown in FIG.6 and FIG.7, compared with the manufacturing method of the sheet | seat 1 for cleaning of embodiment, the folding method of the nonwoven fabric 2 by the folding adhesion part 50 differs.
Specifically, in the second manufacturing method, as shown in FIG. 6, in the joining step, both ends in the direction orthogonal to the drawing direction of the nonwoven fabric 2 are folded back to the center and the ends are overlapped with each other, Only one end portion in a direction orthogonal to the drawing direction of the nonwoven fabric 2 is folded and overlapped with the other end portion.
By adopting the above folding method in the joining process, as shown in FIG. 7, the entire structure including the part where the joining part 3 is formed can have a two-layer structure. Sometimes the bulk of the portion where the joint 3 is formed can be suppressed.

  According to the second manufacturing method of the cleaning sheet 1, the joining step folds one end portion in a direction orthogonal to the drawing direction of the nonwoven fabric 2 and overlaps the other end portion, so that the joining portion 3 is formed. Thus, the entire structure including the portion can be made into a two-layer structure, and the bulk of the portion where the joint portion 3 is formed during the production of the secondary raw fabric 2B can be suppressed.

  Moreover, according to the cleaning sheet 1 manufactured by the second manufacturing method, the joint portion 3 is formed by folding the nonwoven fabric 2 in two and joining the end portions in the longitudinal direction X to each other. The entire structure including the portion where 3 is formed can be made into a two-layer structure, and when the inside of the packaging body 30 of the cleaning sheet packaging body 100 is laminated, Bulkiness can be suppressed.

(Modification 1)
For example, the example shown in FIGS. 8 and 9 is different from the cleaning sheet 1 of the embodiment in that the joining method when forming the joining portion 3 </ b> A and that the perforation 4 is not formed on the nonwoven fabric 2.
Specifically, the cleaning sheet 1 according to the modified example 1 fixes the entire end portion along the width direction Y when the end portions in the longitudinal direction X of the nonwoven fabric 2 are overlapped to form the joint portion 3A. Instead, as shown in FIG. 8, the adhesive portions 3 a that are intermittently scattered at arbitrary intervals along the width direction Y are fixed. As described above, the cleaning sheet 1 according to the modified example 1 can be easily released from the bonded state by fixing the bonding portions 3A at the bonding portions 3a that are scattered at arbitrary intervals. Therefore, the joint portion 3A can function as a cutout portion extending in the width direction Y.
Therefore, the cleaning sheet 1 according to Modification 1 has a configuration in which the perforation 4 is not formed on the nonwoven fabric 2 as shown in FIGS. 8 and 9.

Next, a method for manufacturing the cleaning sheet 1 according to Modification 1 will be described.
First, the non-woven fabric 2 is pulled out from the primary raw fabric 2A of the non-woven fabric 2 wound in a roll shape. Are bonded at the adhering portions 3a that are intermittently scattered at every arbitrary interval to form a bonding portion 3A (bonding step). In the joining step, for example, an adhesion method using an adhesive such as hot melt, or an adhesion method such as heat sealing or ultrasonic sealing is used.
Next, the secondary fabric 2B is produced | generated by winding up the nonwoven fabric 2 in which the junction part 3A was formed in roll shape (secondary fabric production | generation process).
Finally, the nonwoven fabric 2 is pulled out from the secondary raw fabric 2B of the nonwoven fabric 2 wound in a roll shape, and is cut into a predetermined size in a direction orthogonal to the direction in which the joining portion 3A is formed, whereby the cleaning sheet 1 is manufactured. (Cutting process).
In addition, after forming 3 A of joining parts in a joining process, it is also possible to cut | judge for every predetermined size as it is, without producing | generating secondary raw fabric 2B.

Next, a method for using the cleaning sheet 1 according to Modification 1 will be described.
First, the user peels off the cover member 20 while picking the knob portion 21 of the cover member 20 provided on the package body 30 of the cleaning sheet package body 100 to expose the opening 11.
Next, the user takes out and uses the cleaning sheet 1 through the opening 11 by pulling the cleaning sheet 1 upward while pinching it.
For example, when priority is given to workability, a hand is put into the cleaning sheet 1 formed in a cylindrical shape, and the floor or table to be cleaned is wiped off.
Further, when the dirt is severe, a hand is placed on the surface of the cleaning sheet 1 and the floor, the table or the like is wiped with the cleaning sheets 1 for two layers.
Further, when it is desired to remove a small amount of dirt in a wide range, after the cleaning sheet 1 is spread in the longitudinal direction X by releasing the bonding state of the bonding portion 3a in the bonding portion 3A formed on the cleaning sheet 1. Wipe floors and tables.

  As described above, according to the cleaning sheet 1 according to the modified example 1, when the cutout portion forms the joint portion 3A, the end portions in the longitudinal direction X of the nonwoven fabric 2 can be arbitrarily aligned along the width direction Y. Since it is formed by being fixed intermittently at intervals, it can be easily expanded in the longitudinal direction X by releasing the bonding state of the bonding portion 3a in the bonding portion 3A without providing the perforation 4.

  Moreover, according to the manufacturing method of the cleaning sheet 1 according to the modified example 1, the nonwoven fabric 2 is pulled out from the raw fabric 2A of the nonwoven fabric 2 wound in a roll shape, and the end in the direction orthogonal to the pulling direction of the nonwoven fabric 2 Are joined to each other at an arbitrary interval along the pull-out direction to form a joint 3A, and a joint 3A of the nonwoven fabric 2 in which the joint 3A is formed in the joint process. A cutting step of cutting every predetermined size in a direction orthogonal to the formed direction, so that the cut portion forming step for forming the perforation 4 can be omitted, and the manufacturing process can be shortened. Can do.

(Modification 2)
For example, in the example shown in FIGS. 10 and 11, the shape of the joint portion 3 is different from that of the cleaning sheet 1 of the embodiment.
Specifically, the cleaning sheet 1 according to the modified example 2 is formed such that the joint portion 3 projects to the upper surface side of the cleaning sheet 1.
Moreover, as shown in FIG.12 and FIG.13, the sheet | seat 1 for cleaning which concerns on the modification 2 is accommodated in the state (multiple sheet | seats S for cleaning sheets) laminated | stacked inside the package 30 of embodiment. The

  Moreover, the manufacturing method of the cleaning sheet 1 according to the modified example 2 is formed so that the bonding portion 3 protrudes to the upper surface side in the bonding process, as compared with the manufacturing method of the cleaning sheet 1 according to the embodiment. Only differ in.

As described above, according to the cleaning sheet 1 according to the modified example 2, since the joint portion 3 is formed so as to protrude to the upper surface side, The joint portion 3 of the cleaning sheet 1 positioned at the position automatically rises and can be easily pulled out when the user pulls out the cleaning sheet 1.
Note that Modification 2 can be combined with Modification 1.

(Other variations)
In the above embodiment, the wet type nonwoven fabric 2 is described as an example. However, the wet type nonwoven fabric 2 is not limited to this example. Instead of the wet type nonwoven fabric 2, a dry fiber mainly composed of hydrophobic fibers is used. A type of non-woven fabric may be used. Examples of hydrophobic fibers include polyolefin fibers such as polyethylene, polypropylene, and polyvinyl alcohol, polyester fibers such as polyethylene terephthalate and polybutylene terephthalate, and polyamide fibers such as nylon. These can be used alone or in combination of two or more.
