  However, when embossing is performed after plying the base paper, if the sheet is already misaligned or wrinkled at the ply processing stage, it will be embossed with misalignment or wrinkle remaining on the sheet. Not only does it look bad, but there is a problem that the ply is easily peeled off. In addition, in the manufacture of wet sheets such as general toilet cleaners and kitchen cleaners, after embossing, several folds are applied in the direction parallel to and perpendicular to the sheet feeding direction. There has also been a problem that misalignment occurs. In this way, when embossing and folding are performed after ply processing, the sheet may be displaced or wrinkled during ply processing. There is still a problem of poor appearance.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a wet sheet that is easy to fold during manufacture and has a good appearance in a method for manufacturing a wet sheet to be embossed. Is to manufacture.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, the scope of the invention is not limited to the illustrated examples.
As an example of a wet sheet manufacturing method according to the present invention, a toilet cleaner manufacturing method will be described as an example. The wet sheet used in the state where it was made is included.

  As shown in FIG. 1A, the toilet cleaner 1 manufactured according to the present embodiment is obtained by plying (stacking) a plurality of base papers 11 and corresponding to both side edges of the toilet cleaner 1. Is provided with a contact embossing e1. In addition, the entire surface of the toilet cleaner 1 is provided with design embossing e2.

  Moreover, the toilet cleaner 1 of this embodiment is comprised from the water-decomposable fiber assembly so that it can be discarded as it is in the toilet bowl after cleaning the toilet. As the fiber assembly, natural fibers, synthetic fibers, fibers mixed with these, or the like can be used, and there is no particular limitation as long as the fiber assembly has water decomposability. Suitable raw material fibers include cellulose fibers such as wood pulp, non-wood pulp, rayon and cotton, and biodegradable fibers made of polylactic acid. Further, in order to improve the strength of the base material, polyvinyl alcohol (PVA), carboxymethyl cellulose (CMC) or the like may be blended or coated / coated as a paper strength enhancer.

In addition, a predetermined chemical solution is applied to the toilet cleaner 1 of the present embodiment. Specifically, in addition to the aqueous cleaning agent, a predetermined chemical solution containing auxiliary agents such as a fragrance, a preservative, and a disinfectant is provided. It has been applied. As the chemical solution, an appropriate one can be used. For example, as the aqueous cleaning agent, in addition to the surfactant, a lower or higher (aliphatic) alcohol can be used. As a fragrance | flavor, 1 type or several types can be suitably selected and used out of oily fragrance | flavors, such as orange oil, besides an aqueous | water-based fragrance | flavor. As the preservative, for example, parabens such as methyl paraben, ethyl paraben, propyl paraben and the like can be used. As the disinfectant, alcohol, paraoxybenzoic acid ester, quaternary ammonium salt of monomer, cetylpyridinium chloride, phenoxyethanol, or the like can be used.
In addition, the above-mentioned auxiliary agent for the component of the chemical solution can be appropriately selected, and a component that performs another function may be included in the chemical solution as necessary.

  As shown in FIG. 1 (a), the contact embossing e1 is provided on both surfaces of the sheet with respect to the portions corresponding to the both side edges of the toilet cleaner 1, and the portions subjected to the contact embossing e1 include a plurality of portions. The base paper is crimped. In the present embodiment, since the contact embossing e1 is performed at the stage of ply processing, a ply-processed original fabric roll can be manufactured in a state where there is no wrinkle or misalignment in the sheet. Therefore, even in the subsequent processing stage in which the raw fabric roll is used, the base papers are not easily displaced or wrinkled, and the processing is easy.

  Further, in the case of a general ply-processed sheet, when a chemical solution is applied and in a wet state, the ply process is easily peeled off even if one sheet is taken out, and it is difficult to take out one sheet at a time. On the other hand, since the toilet cleaner 1 of this embodiment is provided with the contact embossing e1 on both side edges, the ply process is difficult to peel off even in a wet state.

  As shown in FIG. 1A, the design embossing e2 is uniformly applied to both surfaces of the sheet except for both side edges of the toilet cleaner 1 to improve the design of the toilet cleaner 1. ing. Further, by applying the design embossing e2, the sheet can be made bulky, and can be made soft and comfortable to touch, so that it is possible to make the sheet easy to use.

The toilet cleaner 1 according to the present embodiment is folded into eight folds so as to be even when folded once, once along the longitudinal direction, and twice along the lateral direction, as shown in FIG. 1 (b), for example. It is. Then, it is stored in a folded plastic case, packaging film, etc. in a folded state, and is expanded and used as needed during use.
In addition, how to fold the toilet cleaner 1 is not limited to eight folds as shown in FIG. 1B, and may be folded into two or four, for example. Further, the folding method is not limited to the above-described example. For example, the folding may be performed so as not to be equal when folded.

Moreover, the convenience of the toilet cleaner 1 can be improved by providing a perforation 2 in the toilet cleaner 1. Specifically, as shown in FIG. 2, the perforation 2 can be provided at the center of the toilet cleaner 1 in the longitudinal direction and can be cut off by the perforation 2. Therefore, it is possible to use it in a cut-out state.
Here, the contact embossing e1 is applied to both side edges of the toilet cleaner 1 so that the sheets are pressure-bonded to each other, so that even when a part of the perforation 2 is cut off, the ply processing is peeled off from the edge. It has become difficult (see FIG. 2).

  As an example, the perforation 2 is provided in the central portion in the longitudinal direction of the toilet cleaner 1 in only one row in the direction orthogonal to the longitudinal direction. However, the present invention is not limited to this, and for example, 2 in the direction orthogonal to the longitudinal direction. You may provide more than a row | line | column and may provide along a longitudinal direction.

In the present embodiment, the contact embossing e1 is provided on both side edges of the toilet cleaner 1, and the design embossing e2 is provided on the entire surface of the sheet except for the both side edges of the toilet cleaner. It can be arbitrarily changed as long as it is within. For example, the configuration in which the vicinity of the perforation 2 is not embossed may be used, or the design embossing e2 may be applied on the contact embossed e1.
The contact embossing e1 and the design embossing e2 are provided on both sides of the sheet, respectively, but may be provided only on one side.

  Next, a method for manufacturing the toilet cleaner 1 according to this embodiment will be described.

  As shown in FIG. 3, the toilet cleaner 1 according to the present embodiment includes a ply processing step (S1) for plying a plurality of base papers by applying contact embossing, and a design embossing for the ply-processed sheet. A design embossing step (S2) for applying a perforation, a perforation processing on the design embossed sheet, folding and folding, applying a chemical solution, and packaging in a pack (S3) Manufactured by a manufacturing method.

  First, the ply processing step (S1) will be described in detail using FIG. Note that the number of primary raw rolls 10 used for ply processing can be changed as appropriate as long as there are two or more. However, in the following description, an example in which two are used will be described.

  In the ply processing step (S <b> 1), as shown in FIG. 4, first, contact embossing e <b> 1 is performed by the contact embossing roll 12 on the base paper 11 fed out from the two primary raw rolls 10. The contact embossing e1 is applied to a portion corresponding to the edge of the toilet cleaner 1, and two base papers 11 are pressure-bonded and plyed.

  Then, as shown in FIG. 5, the ply-processed sheet is wound into a roll shape to produce a secondary raw roll 20. Here, the contact-embossed e1 is applied to the ply-processed sheet, so that no slippage or wrinkle occurs when winding, and the ply-processed sheet can be wound in a clean state.

Here, the primary web roll 10 may have a width corresponding to a plurality of sheets of the toilet cleaner 1, for example, as shown in FIG. 5, the primary web having a width of 3 sheets. The secondary raw roll 20 may be manufactured with the roll 10. Here, when the primary fabric roll 10 has a width of three sheets, a portion corresponding to the edge of the side surface of the toilet cleaner 1 is required for a total of six rows, and therefore, shown in FIG. As described above, the contact embossing e1 is applied to the portion corresponding to the edge of the side surface of the toilet cleaner 1 for six rows.
In addition, when the primary raw fabric roll 10 has the width | variety for several sheets of the toilet cleaner 1, it is necessary to have the cutting process which cut | disconnects a sheet | seat for every unit number of sheets in a subsequent process. The timing for carrying out the cutting step is not particularly limited as long as it is before the finishing step (S3), but the cutting after the design embossing e2 is applied to the entire surface of the sheet is the same after cutting every unit number of sheets. Since it is more efficient than performing the design embossing e2 sheet by sheet, it is desirable to carry out after the design embossing (S2).

  As shown in FIG. 6, the design embossing step (S2) is performed on the entire surface of the sheet by a design embossing roll 22 with respect to the ply-processed sheet 21 fed from the secondary fabric roll 20 after plying. e2 is applied. The design of the design embossing e2 can be selected as appropriate. As an example, FIGS. 1, 2 and 7 illustrate an embodiment in which an embossed design having a U-shaped and inverted U-shaped pattern is provided. ing.

  Here, the design embossing e2 is provided not only for improving the design of the sheet, but also for the purpose of improving the flexibility, bulkiness, wiping, etc. of the sheet. Is not crimped. Therefore, although it is possible to peel off the sheet at the design embossed e2, the contact embossed e1 is applied to both side edges of the sheet as shown in FIGS. Therefore, the ply is difficult to peel off.

  The design embossing process (S2) can also be technically performed immediately after the contact embossing e1 is performed in the ply processing process (S1). However, when the design embossing e2 is applied, the sheet becomes bulky. Therefore, if the secondary embossed roll is manufactured by winding the design-embossed sheet, the secondary original roll itself becomes very bulky and is transported. It becomes inconvenient to handle. Moreover, when it winds with strong force, a sheet | seat will be crushed and the merit, such as the softness | flexibility of a sheet | seat obtained by design embossing, and bulkiness, will be impaired. Therefore, as in the present embodiment, the design embossing process (S2) is preferably performed on the ply-processed secondary raw roll.

  As shown in FIG. 6, the finishing step (S3) is performed after design embossing e2 is performed, and after the toilet cleaner 1 is cut into a single piece, perforation processing, folding processing, chemical application, In this process, the toilet cleaner 1 is completed through a series of pack packaging processes.

  In addition, in FIG. 1 (a), (b) shows the Example of this embodiment which provided the perforation 2 in the longitudinal direction center part of the toilet cleaner 1 as an example, and was folded in two at the position of the perforation. However, without being limited to the illustrated example, for example, the position where the perforation 2 is provided and the folding method can be appropriately changed.

  Moreover, as long as a finishing process (S3) is a process including a folding process and a chemical | medical solution application | coating process, you may add or delete a process suitably as needed, for example, it is good also as a process which does not include a perforation processing process. .

<Modification 1>
In this embodiment, as shown in FIGS. 7 (a) and 7 (b), the embossed design of the contact emboss e1 may be matched with the design emboss e2, and the contact emboss e1 may be provided on both sides of the sheet (before folding) FIG. 7A, see FIG. 7B after folding. The contact embossing e1 is applied to prevent ply peeling, and the design embossing e2 is applied to improve the design, bulkiness, flexibility and the like. It is possible to adapt the design. Thus, the design of the toilet cleaner 1 can be further improved by combining the embossed design.
As described above, the contact embossing e1 is desirably applied to both sides to unify the sheet design, but may be provided only on one side.

<Modification 2>
In this embodiment, as shown in FIGS. 8 (a) and 8 (b), the contact embossing e1 may be provided in a dotted line shape at regular intervals (before folding, FIG. 8 (a), after folding (See FIG. 8B). In the present embodiment, the contact emboss e1 is linearly provided on the edge of the side surface of the toilet cleaner 1 and is in a folded state (see FIG. 1B). Since the edge part of the side surface of will overlap, the side part of the toilet cleaner 1 will become hard. Therefore, when used, the toilet side surface of the toilet cleaner 1 may be damaged by the hard side surface of the toilet cleaner 1 or it may be difficult for the user to clean. Therefore, as in Modification 2, by providing the contact embossed e1 in a dotted line shape, the side surface of the sheet can be prevented from becoming hard, and the toilet cleaner 1 can be easily used.
In the second modification shown in FIG. 8, an example in which the contact embossed e1 is provided in a row in a dotted line at a constant interval is shown. However, the contact embossed e1 can prevent the plyed sheets from being displaced or wrinkled. The present embodiment is not limited to this example as long as the sheets can be pressure-bonded. As another embodiment, for example, a plurality of rows may be provided instead of a single row, and the intervals at which the embosses are provided may be appropriately set instead of being constant. The shape of the contact emboss e1 may be a dot shape. It may be provided.

  As described above, according to the present embodiment, in the step of plying the base paper 11 fed from the primary raw roll 10, the contact embossing e1 is applied to the portions corresponding to the both side edges of the toilet cleaner 1. The secondary sheet roll 20 can be obtained by bonding a plurality of sheets in a state free from displacement and wrinkles.

  Next, the design embossing e2 is applied to the entire surface of the ply-processed sheet 21 fed out from the secondary web roll 20, so that the sheet is uniformly embossed on the entire surface without any deviation or wrinkle. Processing can be performed.

  And in the next finishing process, the sheet without misalignment or wrinkles can be neatly creased or perforated and folded without any misalignment or wrinkles, so it looks good and has excellent design. The toilet cleaner 1 can be manufactured.

In this way, contact embossing is performed at the stage of plying the base paper, and design embossing is performed on the sheet fed from the raw roll, so that the entire surface of the sheet can be embossed in a uniform state. The sheet can be creased cleanly without any misalignment or wrinkles.
Here, as usual, if both the contact embossing and the design embossing are performed on the sheet fed from the ply-processed secondary raw roll, the sheet is already displaced or wrinkled at the ply processing stage. If so, the sheet is embossed with misalignment and wrinkles remaining on the sheet. Therefore, the appearance of the sheet may be deteriorated, or sufficient adhesive force may not be obtained, and the ply may be easily peeled off.
Further, for example, if both the contact embossing and the design embossing are performed at the time of ply processing, the secondary material roll becomes very bulky due to the design embossing, and handling becomes inconvenient when carrying. Further, when the secondary roll is wound with a strong force, the sheet is crushed, and the advantages such as flexibility and bulkiness of the sheet obtained by design embossing are impaired. .

  In the present invention, contact embossing is applied at the time of ply processing, and design embossing is applied to the sheet fed from the secondary raw roll, thereby solving the above-mentioned problems and processing at the time of folding because there is no deviation or wrinkle. It became possible to manufacture a toilet cleaner 1 that was easy and good-looking. Furthermore, as shown in the first modification, the design of the toilet cleaner 1 can be improved by matching the design of the contact embossing and the design embossing. As shown in the second modification, the contact embossing is indicated by a dotted line. By making it into a shape, the functionality of the toilet cleaner 1 can be improved.

  In the ply processing step (S1) of the present embodiment, as described above, it is possible to ply a plurality of base papers, but it is not always necessary to use the same type of base papers for processing. It can be changed. For example, when plying three sheets of paper, if the center sheet is a rigid sheet and the outside is a soft sheet that can be entangled with dust, it will have rigidity that will not break even if rubbed strongly. However, it is possible to obtain a sheet that is flexible and comfortable to touch, and that easily removes dust.
