Description

  The present invention relates to a thin paper product such as a box-type tissue paper manufactured by stacking a plurality of original fabrics while being folded.

  Scented tissue paper is well known. The fragrance imparting step in the production is mainly performed by applying a chemical solution in which a microcapsule enclosing a fragrance is dispersed in a solvent such as glycerin to a continuous sheet fed from a raw roll that is later made into tissue paper. It has become.

  The scented tissue paper manufactured by this method is rubbed with the slit formed in the carton box when the user takes out the tissue paper, or the user himself grasps the microcapsule to break it. The fragrance is volatilized and the scent spreads.

  Therefore, in the tissue paper with fragrance produced by this method, since the fragrance is enclosed in the microcapsule, the fragrance can be maintained without volatilizing until the last one, and the fragrance itself is not oxidized and is kept with time. There is a merit that there is no typical scent change.

On the other hand, in recent years, tissue paper is often used for applications that directly touch the skin. Therefore, a fragrance is added to a storage box for storing tissue paper without directly applying chemicals to the tissue paper. There is also known a scented tissue paper product configured to indirectly impart a scent to a group of tissue paper contained in the tissue paper. The storage box in which tissue paper is stored at the time of product is generally called a carton box, and an opening for taking out the tissue paper is formed on the top surface, and a film with a slit is attached to this opening. Forms a roughly rectangular parallelepiped. A fragrance is mixed with hot melt paste used when assembling such a carton box so that the scent component volatilizes and spreads inside the carton box, and the scent is indirectly added to the tissue paper group stored therein. And is configured to be taken out from the slit as a scented tissue paper at the time of use.

  However, tissue paper products coated with a microcapsule drug solution in which a fragrance is encapsulated are expensive to manufacture microphone capsules. In addition, since the user does not use the microcapsule consciously, in order to ensure that the scent is scented at the time of use, the chemical must be applied to the entire tissue paper. Moreover, the chemical solution must be applied to all the tissue papers stored in the storage box. However, in actual use, only a part of the applied microcapsules is broken, and most of the microcapsules are not broken and are discarded together with the used tissue paper. Therefore, it cannot be said that cost effectiveness is good, and it is expensive and not preferable in terms of environment. Furthermore, since it is necessary to handle the microcapsules so as not to break after the chemical solution coating step, there may be a case where the operation is deteriorated such as a decrease in the operation speed.

  On the other hand, the method of mixing fragrances with hot melt glue used for assembling carton boxes and the method of directly applying fragrances to carton boxes are complicated operations and cause a lot of operational troubles, such as affecting the adhesive properties of adhesives. There is a possibility. In addition, the assembly of the carton box is usually performed by bonding the end face pieces constituting the side surface of the carton box. The carton box is made of relatively strong thick paper. Therefore, after the carton box is formed, the hot melt adhesive is positioned between the thick papers, so that the fragrance in the hot melt adhesive does not spread effectively inside the box. The tissue paper group may not be given a fragrance. In particular, at a time or place where the temperature is low, the hot melt adhesive is likely to be hardened and the volatilization becomes insufficient, and the scent may not be sufficiently imparted. In addition, the fragrance component may ooze out on the outer surface of the carton box, and the carton box itself may unintentionally emit a scent.

  Therefore, the main problem of the present invention is to provide a method for manufacturing a thin paper product that solves problems such as operational troubles, a decrease in operation speed, cost, environmental aspects, and design freedom by the conventional methods listed above. There is to be.

The present invention that has solved the above-described problems and the effects thereof are as follows.
<Invention of Claim 1>
In supplying a plurality of continuous sheets each consisting of a plurality of plies to an interfolder and stacking while folding, to form a folded laminated continuous sheet,
Prior to folding and stacking, a continuous sheet with a scent that emits a fragrance by applying a fragrance to some of the continuous sheets of the plurality of continuous sheets,
A method for producing a thin paper product, wherein the folded laminated continuous sheet has a scented continuous sheet arranged in a predetermined layer.

(Function and effect)
In the present invention, a scented continuous sheet is folded and stacked together with other scentless continuous sheets in an interfolder to form a folded laminated continuous sheet. Accordingly, by cutting this and storing it in a storage box, a thin paper product having a folded laminate in which a scented thin paper is arranged at a predetermined location can be obtained.

  And since the scented continuous sheet in this invention gives off the fragrance | flavor to which the fragrance | flavor was apply | coated, naturally the scented thin paper in the thin paper product which consists of this naturally also releases a fragrance. Therefore, in such a thin paper product, the fragrance released from the scented thin paper spreads in the storage box, and the scent is transferred to the thin paper to which the fragrance made of another continuous sheet is not applied. The fragrance imparting process in this new thin paper product is not a mechanism in which the fragrance is scattered by breaking the microcapsule due to an external action as in the conventional product, and therefore the waste of the fragrance is extremely small. That is, since only a part of the thin paper is coated with the fragrance, there is little fragrance that is wasted after use. Moreover, since it can apply | coat to a continuous sheet directly, without having to enclose a fragrance | flavor in a microcapsule, it can manufacture at low cost. In addition, it does not require careful handling like a microcapsule and is easy to operate.

  On the other hand, in the thin paper product by the manufacturing method of the present invention, adjacent to the scented thin paper is another thin paper stored in the storage box. Unlike a product in which a fragrance is mixed with a conventional adhesive, the fragrance is not sandwiched between thick papers, so that the fragrance spreads reliably in the storage box. Further, there is no case where the scent permeates into the outer surface of the storage box and the storage box does not smell unintentionally.

  On the other hand, in the present invention, the ratio of the scented continuous sheet in the folded laminated continuous sheet is increased or decreased by increasing or decreasing the number of scented continuous sheets continuously supplied to the interfolder. The number of scented thin papers arranged will be increased or decreased. For this reason, the intensity | strength of the fragrance in a storage box can be easily adjusted by changing the ratio of the number of the continuous sheet with a fragrance supplied to an inter folder, and the number of continuous sheets without a fragrance.

  Moreover, it is possible to adjust the scent imparting time etc. at the time of a product by setting arbitrarily the position in the folding lamination | stacking continuous sheet of a continuous sheet with a fragrance. For example, if a continuous sheet that becomes a thin paper located in the uppermost layer when a thin paper product is later used is a scented continuous sheet, the thin paper that is first taken out by the user after opening the product becomes scented and used Kahara will be removed from the storage box at an early stage after the start. On the other hand, if the thin paper located at the bottom is made scented, the scent will remain in the storage box for a long time, and the scent can be transferred to other non-scented thin paper for a long time. .

  As described above, the manufacturing method of the present invention can extremely easily change the design such as fragrance strength. For example, an optimum thin paper product can be easily manufactured in consideration of temperature, humidity, consumer preference, cost, etc. Is possible.

  In addition, if the fragrance A is applied to some continuous sheets and the fragrance B is applied to some other continuous sheets, the fragrance A and B are mixed while being mixed in the storage box. It is also possible to transfer the scent to the coated thin paper.

  In the present invention, a part of the plurality of continuous sheets supplied to the interfolder is a scented continuous sheet coated with a fragrance, and all continuous sheets are scented continuous sheets. Absent.

(Function and effect)
Since the fragrance is applied before being attached to the original roll support portion of the interfolder, the operation can be performed without providing a new fragrance application facility to the existing interfolder.

<Invention of Claim 4>
The manufacturing method of the thin paper product of Claim 2 which apply | coats a fragrance | flavor with respect to a continuous sheet in the path | route from the said original fabric roll support part to a folding mechanism part, and makes it a continuous sheet with a fragrance.

(Function and effect)
Since the continuous sheet coated with the fragrance is immediately laminated by another continuous sheet, the volatilization of the fragrance during the operation process can be reduced. Most of the applied fragrance can be held in the storage box, and waste of the fragrance can be reduced.

<Invention of Claim 5>
The manufacturing method of the thin paper product of any one of Claims 1-4 which makes a continuous sheet located in the lowest part when it is made into a folding lamination | stacking continuous sheet with a scented continuous sheet.

(Function and effect)
If the continuous sheet, which is located at the bottom when folded into a laminated continuous sheet, is made into a continuous sheet with scent, the thin paper at the bottom can be made scented and stored when it is later made into a thin paper product. A product in which the fragrance stays in the box for a long time can be obtained, and a tissue paper product can be obtained in which the scent can be transferred to other scentless tissue paper over a long period of time. Moreover, since a fragrance | flavor is not pinched | interposed into thick paper like the product which mixed the fragrance | flavor with the conventional adhesive agent, a fragrance spreads reliably in a storage box.

<Invention of Claim 6>
In a thin paper product in which a folded laminate formed by folding a pair of thin paper sheets by a pop-up method is stored in a substantially rectangular parallelepiped storage box,
A thin paper product, wherein only a part of the thin paper constituting the folded laminate is a scented thin paper.

(Function and effect)
In the thin paper product of the present invention, the fragrance released from the scented thin paper spreads in the storage box, and the scent is transferred to the thin paper to which the fragrance made of another continuous sheet is not applied. Since the fragrance imparting process in the thin paper product is not a mechanism in which the fragrance is scattered by breaking the microcapsule due to an external action as in the conventional product, the fragrance is very little wasted. That is, since only a part of the thin paper is coated with the fragrance, there is little fragrance that is wasted after use. Moreover, since it can apply | coat to a continuous sheet directly, without having to enclose a fragrance | flavor in a microcapsule, it can manufacture at low cost.

<Invention of Claim 7>
The thin paper product according to claim 6, wherein only the thin paper located at the bottom, or only the thin paper located at the bottom and the thin paper located above the thin paper is a scented thin paper.

(Function and effect)
Easy to manufacture. Further, if the thin paper located at the bottom or the like has a scent, the scent will remain in the storage box until the end, and the scent will be transferred to other scentless thin paper over a long period of time. From the scented thin paper used as a scent to the last sheet, a scented thin paper can be used.

<Invention of Claim 8>
The thin paper product according to any one of claims 6 and 7, wherein a color or / and embossing is imparted to the scented thin paper that emits the fragrance.

(Function and effect)
By coloring or embossing only the scented thin paper, the user can visually distinguish between the scented thin paper and the non-scented thin paper. It becomes like this. Therefore, when the scent is disgusted during use, only the scented thin paper can be easily removed. The color may be dyed on the whole tissue paper or may be dyed partially. Moreover, you may color a geometric pattern like a printed pattern. Moreover, you may give embossing the whole thin paper, or partially. In embossing, embossing when plying a plurality of sheets, so-called ply bonding embossing, may be performed only on scented thin paper with a pattern different from other thin paper. Furthermore, you may carry out so that it may have coloring and embossing together.

  As described above, according to the present invention, a thin paper product and a method for producing the same are provided, which solves problems such as operation troubles, a decrease in operation speed, costs, environmental aspects, and design freedom.

Hereinafter, embodiments of the present invention will be described in detail.
FIG. 1 shows a folded plate type interfolder 1 which is an object of the present invention. In the figure, a secondary web roll R set on the web roll support 2 of the interfolder 1 is shown. The required number of secondary raw rolls R are set side by side in a direction perpendicular to the plane of the drawing. In the case of this example, a plurality of product tissue papers are slit in advance in the width of the product tissue paper by a ply machine. An original fabric roll R wound with a double width, for example, a double width, is set. As the ply machine, for example, as shown in FIG. 8, the primary continuous sheets 101 and 102 fed out from a plurality of primary raw rolls JR and JR are overlapped and wound and cut into a ring (divided into a plurality in the width direction). A structure for producing a secondary raw roll 110 composed of a plurality of plies is preferably used.

  Secondary continuous sheets (hereinafter simply referred to as “sheets”) 3A and 3B fed from the secondary web roll R are fed into the folding mechanism section 20 through guide means such as guide rollers G1 and G1.

  In the folding mechanism section 20, as shown in FIG. 2, a necessary number of folded plates P, P... Are arranged in parallel to form a folded plate group 21, and each folded plate P, P. Guide rollers G2 and G2 and guide round bar members G3 and G3 for guiding the pair of sheets 3A and 3B fed from the next raw roll are respectively disposed at appropriate positions, and below the folded plates P and P. Is provided with a conveyor 22 that receives and conveys the laminated product 30 that is folded and stacked.

  A folding mechanism using this type of folded plates P, P... Is known, for example, from US Pat. No. 4,052,048, and is generally called a folded plate type or multi-stand type interfolder. As shown in FIG. 3, the sheets 3A, 3B... Are stacked while being folded in a Z shape and the side edges of the adjacent sheets 3A, 3B.

  The relationship between the folding mechanism and the folding plate is shown in FIGS. Briefly described, as shown in FIGS. 4 to 7, first, a pair of sheets 3A and 3B is guided to each folded plate P. At this time, the sheets 3A and 3B are side end portions by a guide round bar member G3. Guided while being shifted in position so that they overlap each other. Here, assuming that the sheet whose side edge overlaps with the lower side when guided by the folded plate is the first sheet 3A, and the sheet that overlaps with the upper side is the second sheet 3B, these sheets 3A, 3B, as shown in FIG. 3 and FIG. 5, the side end e1 that does not overlap the second sheet in the first sheet 3A is folded back to the upper side of the second sheet 3B by the side plate P1 of the folded plate, As shown in FIGS. 3 and 6, the side end e2 of the second sheet 3B that does not overlap the first sheet 3A is folded downward so as to be drawn onto the folded plate from the slit P2 of the folded plate P. At this time, as shown in FIGS. 3 and 7, the uppermost folded end e3 of the sheet 3A folded and stacked on the upstream folded plate P is moved from the slit P2 of the folded plate P to the second sheet 3B. Folded part It is guided to. Thus, the sheets 3A, 3B... Are folded in a Z shape and the side edges of the adjacent sheets 3A, 3B are overlapped with each other.

  In this way, the folded laminated continuous sheet 30 manufactured by the interfolder 1 is cut at a predetermined interval in the longitudinal direction in the subsequent equipment.

  After that, the cut laminate is boxed in the storage box, and the boxing operation to the storage box is performed by placing the storage box in the unfolded state with the side face opened so that the tissue paper outlet is located on the upper surface. The assembly is performed by inserting a cut laminate that flows on the conveyor 22 from the side opening. Therefore, the tissue paper located at the bottom layer in the laminate on the conveyor 22 is located at the bottom when the boxed product is used.

  Thus, a so-called pop-up tissue paper product is produced in which the next tissue paper is drawn when the topmost tissue paper is taken out.

  In the interfolder 1 as described above, the present invention has a scent that releases a fragrance by applying a fragrance to some of the continuous sheets 3A, 3B, 3A, 3B... Prior to folding and stacking. As a continuous sheet, a folded laminated continuous sheet in which a scented continuous sheet is arranged in a predetermined layer is formed. As is clear from the operation mechanism of the interfolder 1 described above, each of the folded plates P, P... Of the folding mechanism unit 20 has continuous sheets 3A, 3B fed from the corresponding secondary raw rolls R, respectively. 3A, 3B... Are supplied. Accordingly, if any or a part of the continuous sheets supplied to the folded plates P, P ... are made scented with a fragrance applied, the folded laminated continuous sheet in which the scented continuous sheet is arranged in a predetermined layer 30 is formed. The tissue paper product formed from the folded laminated continuous sheet 30 is a tissue paper with a fragrance that emits a fragrance in which only a part of the tissue paper in the storage box is coated with a fragrance, from the above-described boxing operation. It will be.

The number of tissue paper to be taken out at the time of product is made into scented tissue paper, which is determined by the selection of which of the folded sheets P, P the continuous sheets 3A, 3B,. . For example, in the above-described folding mechanism 20, the most upstream Kanagawa toward the folded plate P _X located on the most downstream from folded plate P ₁ located (leftward in FIG. 2), for sequentially continuous sheet are stacked , when it is a folded laminated continuous sheet 30, the continuous sheet fed to the folding plate P ₁ of the most upstream is located at the lowermost portion (closest to the conveyor belt 22), fed to the folding plate P _X in the most downstream in the opposite The continuous sheet is positioned on the uppermost layer. Therefore, the continuous sheet 3A supplied to the most upstream folded plate P _1, if 3B to those of scented perfume has been applied, at the time of product tissue paper (last and previous above more than and bottommost The tissue paper to be taken out becomes a tissue paper product with a fragrance.

  Here, prior to folding and laminating, as a method of applying a fragrance to any one of the continuous sheets, a secondary raw roll R made of a continuous sheet pre-applied with a fragrance is applied to any original of the interfolder 1. Although it is simple to attach to the anti-roll support portion, for example, as shown in FIG. 1, it is particularly desirable for the sheet guide path from any of the original roll support portions 2 to the folding mechanism portion 20. It is also possible to provide the fragrance applicator 10 on the sheet guide path from the exit side of the slitter device (not shown) to the folding mechanism unit 20 so as to continuously apply the fragrance.

  The fragrance applicator 10 of this example has a pair of rolls 11 and 12 configured to continuously supply the fragrance to the outer peripheral surface of one roll 11, and the sheets 3 </ b> A and 3 </ b> B are sandwiched between the rolls 11 and 12. Perfume is applied in a printing manner. Thus, the fragrance is applied to the sheets 3 </ b> A and 3 </ b> B that are in the process of being transferred from the raw roll support portion 2 to the folding mechanism portion 20. Particularly in this case, by not providing the ply machine with the emboss bonding means as described above, it is possible to stabilize the processing without reducing the processing speed of the ply machine. In addition, you may make the form which sprinkles a fragrance | flavor over the width direction of a continuous sheet. In this case, the operation speed of the interfolder is preferably 150 m / min or less, particularly 120 to 140 m / min.

(Other)
Needless to say, the present invention can be applied not only to the folded plate type interfolder as in the above example but also to other types, for example, a roll type interfolder. In addition, the present invention has, for example, a type in which an original fabric roll having the same width as that of the product tissue paper is set, or a width more than twice the width of the product tissue paper, and this is provided in the interfolder before folding. It can also be applied to a known interfolder such as a so-called rotary interfolder that is divided into continuous sheets having a product tissue width by a slitter. However, the present invention is an inter-folder of the type in which the raw roll R that has been slit into the width of the product tissue paper in advance by a ply machine and wound up in multiple times the width of the product tissue paper is set as in the illustrated example. Particularly preferred.

  In addition, as a fragrance | flavor used in this invention, the known fragrance | flavor which emits a fragrance only by application | coating can be used. It is preferably volatile. Specific examples include natural fragrances such as menthol, mint, lavender, and rosemary, rose fragrance, citrus fragrance, cypress fragrance, and synthetic fragrances. Is mentioned.

  The present invention can be used not only for boxed tissue paper, but also for other types of products such as kitchen paper and paper towels that are stored in a storage box after creating a laminate using an interfolder.
