Description

The present invention, in the interior of the carton sanitary paper bundle to a method of manufacturing a storage cartons containing sanitary paper.

  In general, tissue paper widely used in homes and offices is marketed in the form of cartons containing tissue stored in the internal space of a box (hereinafter referred to as “carton”). The carton of tissue containing cartons has a cut line (perforation, etc.) for forming a tissue outlet on one side of the carton. The tissue inside the carton can be taken out.

  In the tissue with cartons as described above, the tissue is usually a ply in which two or more base papers are overlapped, and is stored inside the carton as a sanitary paper bundle in which a plurality of sets of plies are folded. The sanitary paper bundle has a repeating structure in which one ply is folded, another ply is sandwiched between the folded plies, and the other ply is folded. When the ply is taken out from the carton, the ply located immediately below the ply is pulled out, and the ply can be sequentially taken out by a so-called pop-up method (see, for example, Patent Documents 1 to 3). ).

  In addition to tissue paper, the carton as described above stores paper towels such as kitchen paper, toilet paper other than rolls, and sanitary paper (also referred to as “disposable thin paper”) such as Watting (paper cotton). Widely used as a box for

  Sanitary paper stored in a carton as described above (hereinafter referred to as “sanitary paper in a carton”) can be removed in a pop-up manner, so that sanitary paper can be removed. There is an advantage that it is easy. However, at the start of use, the hygienic paper bundle is stored in a relatively dense state in the inner space of the carton, so that there is a problem that the uppermost ply cannot be pulled out well. That is, since the uppermost ply is strongly pressed against the inner surface of the carton, there is room for improvement in that the ply may be broken when pulled out.

  Particularly in recent years, so-called slim type sanitary sanitary paper in which a sanitary paper having the same number of plies as that in the past is housed in the inner space of the carton that is thinner than that of the conventional product is also commercially available. In such a slim type sanitary paper with a carton, the sanitary paper bundle is stored in a denser state than the conventional product, and the above-mentioned problems when pulling out the uppermost ply are more remarkable. There is a risk of becoming.

The present invention has been made in view of such problems of the prior art. Even at the start of use, the uppermost ply can be pulled out well, and the sanitary paper with cartons that are difficult to break is efficiently used. The manufacturing method of the sanitary paper with a carton which can be manufactured automatically is provided.

As a result of intensive studies to solve the above problems, the inventor of the present invention uses a folding plate type processing machine with one additional folding plate to fold back the uppermost ply again to form a folded portion. It has been found that the above problem can be solved by making the drawer portion of the two-layered structure into a two-layer structure, and the present invention has been completed. That is, according to this invention, the manufacturing method of the sanitary paper containing a carton shown below is provided.

A sanitary sheet bundle, and a sanitary sheet containing carton , a long ply supply roll and a folding plate corresponding to the number of plies constituting the sanitary sheet bundle, and the uppermost ply was added to wrap the P _U, using a folded plate-type machine having a single folded portion forming folding plate, and has said upper surface, said bottom surface, and the pair of side surfaces, these surfaces Within compartmented Space is formed, the flap for forming the wife surface from each of end edges of the pair of side surfaces between said upper surface and said bottom surface is extended, and forming a square tubular carton (A step), by the folding plate, folded one ply P _n, sandwiching the other plies P _{n + 1} between the folded ply P _n, further repeating the operation of folding the other plies P _{n + 1,} the repeating structure Forming the uppermost layer ply PU, sandwiching the ply P _U-1 positioned immediately below the upper layer ply P _U , and then folding back again by the folding plate for forming the folded portion; position to form a folded portion at the upper side of the ply P _U-1 to a step of obtaining the sanitary paper bundle (C step), and housing the sanitary paper bundle into the inner space of the rectangular tube carton, following In the the step (D step) of forming a wife surface, wherein the step B and the step C is carried out continuously, cartons containing hygienic manufacturing process of the sheet by fixing by folding the flap.

The method for producing sanitary paper with carton of the present invention can pull out the uppermost ply well even at the start of use, and can efficiently produce sanitary paper with carton that is difficult to break.

Hereinafter, the best mode for carrying out the method for producing a sanitary paper with carton according to the present invention will be specifically described with reference to the drawings. However, the present invention broadly includes a method for producing sanitary paper with cartons having the invention-specific matters, and is not limited to the following embodiments.

[1] Sanitary paper bundle:
The sanitary paper bundle obtained by the manufacturing method of the present invention is a sanitary paper bundle in which a plurality of sets of sanitary paper plies are folded and stored in an internal space of a box-shaped carton body, and one ply P _n is folded back, the other plies P _{n + 1} is sandwiched between the folded ply P _n, further which has a repetitive structure of the other plies P _{n + 1} is folded, the ply P _U of the top layer, its after sandwiching the ply P _U-1 located immediately below, further folded again, is sanitary paper bundle of carton accommodating forming the ply P _U-1 of the upper surface side to the folded portion located at the right below .

The sanitary paper bundle is configured by folding a plurality of sets of plies. This “ply” means a stack of two or more base papers such as tissue paper, but also includes a single sheet such as kitchen paper. In other words, the production method of the present invention can be applied to a sheet made of one sheet such as kitchen paper, in addition to a stack of two or more base papers such as tissue paper.

The sanitary paper bundle has a repeating structure in which one ply _Pn is folded, another ply _{Pn + 1} is sandwiched between the folded plies _Pn , and the other ply _{Pn + 1} is folded. have. Sanitary paper bundle having such a structure, the plies P _U of the uppermost layer is taken out from the carton, along with this ply P _U-1 positioned immediately below its withdrawn sequentially retrieve it plies by a so-called pop-up manner Is possible.

  Examples of the “repetitive structure” include a double-fold repeated structure (C hold), a triple-fold repeated structure (Z-fold structure), or a repeated structure obtained by combining these.

Examples of folded repeating structure (C hold), as sanitary paper bundle 10A shown in FIG. 2 (a), facing ply P _V folded back in a V-shape (C-shape) when viewed from the side with one another In this way, a repetitive structure in which a plurality of plies are continuously folded can be mentioned. Examples of 3-fold repeating structure, as sanitary paper bundle 10B shown in FIG. 2 (b), by being sandwiched alternately as ply P _Z folded back in a Z-shape when viewed from the side are opposed to each other A repetitive structure in which a plurality of plies are continuously folded can be given. The repeating structure combining them, as sanitary paper bundle 10C shown in FIG. 2 (c), folded back ply P _V and Z-shaped folded back in a V-shape when viewed from the side (C-shaped) by plies P _Z are sandwiched alternately have include a repeating structure in which a plurality of plies are folded continuously.

  For example, in the sanitary paper 1 with a carton shown in FIGS. 1A and 1B, the ply P folded back in a V shape (C shape) is opposed to each other in the internal space of the carton body 16. This is an example in which a sanitary paper bundle 10 having a two-fold repetitive structure in which a plurality of plies are continuously folded is stored by being sandwiched alternately.

The sanitary paper bundle, in addition to the sanitary paper bundle has a repetitive structure as mentioned above, the plies P _U of the top layer, after sandwiching the ply P _U-1 positioned immediately below them, folded once more Thus, there is a feature in that a folded portion is formed on the upper surface side of the ply PU _-1 located immediately below.

Such sanitary paper bundle, ply P _U of the top layer, since a structure of the two-ply at its folds, the strength of that portion is doubled by a simple calculation. User, since that would elicit ply P _U of the top layer picking high strength folds, in the case where sanitary paper bundle at the start of use is contained in a relatively dense state in the internal space of the carton Even if it exists, the ply of the uppermost layer can be pulled out well, and the ply is not easily broken.

  Further, in such a sanitary paper bundle, the portion exposed from the ply located immediately below the uppermost ply is folded again, and the portion is subjected to its own weight. Therefore, when a sanitary paper bundle is inserted into a square cylindrical carton to produce a sanitary paper with a carton, the uppermost ply is removed due to the wind pressure when the sanitary paper bundle is inserted and the friction between the sanitary paper bundle and the square cylindrical carton. It's hard to drown. Therefore, the ply of the uppermost layer is not likely to be wrinkled or torn, and in addition to being favorable in appearance, poor insertion is unlikely to occur when a sanitary paper bundle is inserted into a square cylindrical carton, and can be manufactured with high yield. is there.

For example, FIG. 1 (a) and cartons filled sanitary paper 1 shown in FIG. 1 (b), and sanitary paper bundle 10 of folded repeating structure in the interior space of the carton body 16 is housed, the uppermost ply P _U However, in this example, after the ply P _U-1 located immediately below is sandwiched, the ply P _U-1 is further folded back to form the folded portion 12 on the upper surface side of the ply P _U-1 located immediately below.

Also, the sanitary paper bundle, the folding portion is preferably the one in which the ends of the uppermost ply P _U is formed by folding back to match the edge of the sanitary paper bundle.

  With the configuration as described above, since the area of the folded portion having high strength can be increased, the user can draw out the uppermost ply better, and the effect that the ply is hardly broken can be improved. it can. Also, since the area where the weight is applied increases, the top layer ply is difficult to be pulled at the time of manufacturing, and the ply is not easily cracked or torn, and the insertion failure when inserting a hygienic paper bundle into a rectangular tubular carton. The effect of making it difficult to occur is also improved.

On the other hand, when even if the folded back ply P _U of the top layer, in which the folded portion (the portion ply overlaps) does not reach the edge, the area of the folded portion is reduced. In such a case, when a user pulls out a ply, a folding part cannot be picked well but there exists a possibility that a ply may be fractured | ruptured.

Furthermore, the sanitary paper bundle, it is preferable that the ends of the ply P _U-1 located at the right under said is sandwiched below the folded portion formed by the uppermost layer of the ply P _U.

With the configuration as described above, it is possible to prevent the ply from being broken by the user pulling out the ply PU _-1 positioned immediately below, which has a low strength.

In addition, with the configuration as described above, it is possible to prevent troubles from occurring due to not only the uppermost ply P _u but also the ply P _u-1 located immediately below it. . In sanitary paper bundle, each ply charged with static electricity, for repelling by the static electricity, not only the plies P _u of its own weight takes hard top layer, ply in the vicinity thereof is in the state easy lifting from sanitary paper bundle. Accordingly, as described above, the ply P _u-1 positioned immediately below the uppermost ply is sandwiched under the folding portion, so that the ply P _u-1 positioned immediately below is also formed by the uppermost ply P _u . fold weight would can take of prevention of wrinkles and tear ply P _u-1, insertion failure or the like of the sanitary paper bundle by the ply P _u-1 is lifted, in advance that the troubles during production occurs can do.

For example, sanitary paper bundle 10 shown in FIG. 1 (b), the folded portion 12, the folded such that the ends of the uppermost ply P _U coincides with the edge of the sanitary paper bundle 10 formed together are an example that is sandwiched on the lower side of the folded portion 12 which the end of the ply P _U-1 located at the right below is formed by plies P _U of the top layer.

  There is no particular limitation on the type of sanitary paper constituting the sanitary paper bundle, and conventionally known sanitary paper can be used. For example, tissue paper (what is called facial paper, decorative paper, etc.), dust paper, paper towels (kitchen paper, etc.), toilet paper (excluding rolls), and disposable paper (such as paper cotton), such as paper pulp technology Handbook 5th edition, see page 459, published January 30, 1992, edited and published by the Pulp and Paper Technology Association).

[2] Sanitary paper in carton:
The sanitary paper with carton obtained by the production method of the present invention includes, for example, a top surface 2, a bottom surface 4, a pair of side surfaces 6, and a sanitary paper with carton 1 shown in FIGS. It is bent into a shape having a pair of end faces 8 and has a box shape in which an internal space capable of storing sanitary paper is formed, and the sanitary paper take-out port is formed on the upper surface 2. And a sanitary paper bundle 10 in which a plurality of sets of sanitary paper plies P stored in the internal space of the carton body 16 are folded. The sanitary paper bundle described above is stored as the sanitary paper bundle 10.

[2-1] Carton body:
The “carton body” is a box-like shape that is folded into a shape having an upper surface, a bottom surface, a pair of side surfaces, and a pair of wife surfaces, and is defined by these surfaces and has an internal space that can store sanitary paper. In addition, the box is formed with an outlet forming cut line so as to match the outer peripheral shape of the sanitary paper outlet.

  The “box shape” is a shape that is folded into a shape having an upper surface, a bottom surface, a pair of side surfaces, and a pair of wife surfaces, and that is partitioned by these surfaces to form an internal space that can store sanitary paper. . This internal space is a space for storing sanitary paper.

  Examples of the “box shape” include hexahedron shapes such as a rectangular parallelepiped shape and a cubic shape. In these shapes, the upper surface and the bottom surface, the one side surface and the other side surface, and the one wife surface and the other wife surface are arranged in parallel so as to face each other. Among these shapes, a rectangular parallelepiped shape is preferable. For example, the sanitary paper 1 with a carton shown in FIG. 1A is an example in which the carton body 16 is formed in a rectangular parallelepiped shape with the side surface 6 side of the carton body 16 as a long side and the pair of wife surfaces 8a and 8b sides as short sides. It is. In addition, in these shapes, those obtained by chamfering the ridge line portions of the two surfaces are also included in the “box shape” in the present specification.

  There are no particular restrictions on the material constituting the carton body. However, it is preferable to use a paper material such as cardboard as a constituent material for the convenience of bending the box. Generally, as these paper materials, for example, those produced using wood pulp, waste paper, etc. as raw materials can be suitably used.

  On the upper surface of the carton body, an outlet forming cut line for forming an outlet for sanitary paper is formed. This “take-out forming cut line” is a cut line provided to form a take-out port for sanitary paper, and is formed in an annular shape that matches the outer peripheral shape of the take-out port. With such a configuration, the user can form the take-out port by breaking the cut line, and can take out the sanitary paper from the take-out port.

  Here, “annular” means a shape in which several lines (cuts) are intermittently arranged so as to partition a certain region. Since a rectangular parallelepiped shape is often used as the carton body, the shape of the outlet is usually a horizontally long ring along the longitudinal direction of the carton body. For example, shapes such as a substantially rectangular shape, a substantially oval shape, and a substantially oval shape can be given. For example, the sanitary paper 1 with a carton shown in FIG. 1A is an example in which a substantially rectangular outlet forming cut line 14 is formed on the upper surface 2 of the carton body 16 so as to coincide with the outer peripheral shape of the outlet. is there.

  As the above-mentioned cut line for forming the outlet, a perforated one is usually adopted. This perforation may be a double perforation arranged so that two perforations are parallel. In addition, a break line for opening that is called a zipper in the packaging industry and bent into a bowl shape (see page 281 of the packaging industry well-known and commonly used technology, issued on December 20, 1978) is adopted. You can also.

  The carton body may be provided with a cut line for another purpose in addition to the above-described cut line for forming the outlet. For example, a push-up piece forming cut line for forming a pair of push-up pieces is formed on a surface (usually the bottom surface) opposite to the surface (usually the top surface) on which the outlet forming cut line is formed This is also a preferred form. A pair of push-up pieces is formed when the push-up piece forming cut line is pressed and broken and bent inside the carton body. Since the sanitary paper inside the carton body is pushed upward by the push-up piece, it is possible to stably pop up from the upper surface outlet to the last sheet of sanitary paper.

  For example, FIG. 4 is a plan view showing a carton blank 110 that is an intermediate body of sanitary paper with a carton. The carton blank 110 has a cut-out line 14 for taking out the outlet formed on the surface that becomes the upper surface 2, and the bottom surface. 4 is an example in which a pair of U-shaped push-up piece forming cut lines 54 is formed at the center of the surface to be 4.

[2-2] Window film:
The carton body may be provided with a window film or may be a so-called filmless carton without a window film. The “window film” is a film material arranged so as to cover the outlet from the inner surface side of the carton body, and has a slit for taking out sanitary paper.

  This window film not only protects sanitary paper from external dust and dust, but also prevents the sanitary paper popped up from falling into the carton due to friction between the slits. It can hold | maintain in the state protruded from the exit.

  The shape of the window film may be any shape as long as it can cover the outlet of the sanitary paper. However, since a horizontally long annular shape is generally used as the shape of the outlet, it is preferable to use a rectangular window film 20 like the sanitary paper 1 with a carton shown in FIG.

  The constituent material of the window film is not particularly limited. For example, plastics such as polyethylene, polypropylene, polyvinyl chloride, polyester, polyvinyl alcohol; printing paper such as glassine paper, kraft paper, Kent paper, India paper, paper such as calligraphy paper, wrapping paper, and processed base paper; be able to.

A “slit” is a break through the window film. Forming direction of the slit is not particularly limited, but is preferably formed in a direction along the long side of the carton containing sanitary paper. For example, the sanitary paper 1 with a carton shown in FIG. 1A is an example in which a linear slit 18 is formed along the long side of the carton body 16 in the center of the window film 20.

[3] Manufacturing method of sanitary paper with carton:
The manufacturing method of the sanitary paper with a carton according to the present invention includes the upper surface, the bottom surface, and the pair of side surfaces, and an internal space defined by these surfaces is formed, and the upper surface, the bottom surface, and the pair of side surfaces. A step (A step) of forming a rectangular tubular carton in which a flap for forming the end face is extended from each end edge of the first ply _Pn , and the folded ply P _n sandwiched other plies P _{n + 1} during a further, by repeating the operation of folding the other plies P _{n + 1,} and step (B process) of forming the repeating structure, the plies P _U of the top layer, After the ply P _U-1 positioned immediately below is sandwiched, the ply P _U-1 is further folded back, and the folded portion is formed on the upper surface side of the ply P _U-1 positioned immediately below to obtain the sanitary paper bundle. A step (C step), and a step (D step) of storing the sanitary paper bundle in the internal space of the rectangular tubular carton and then forming the end face by folding and fixing the flap. It is to be prepared.

[3-1] Square tubular carton forming step (step A):
In the production method of the present invention, first, a rectangular tubular carton is formed. A “square cylindrical carton” is a cylindrical member that is bent into a shape having an upper surface, a bottom surface, and a pair of side surfaces, and is defined by these surfaces and has an internal space. A flap for forming a wife surface is extended from any one of the side surfaces.

  In the manufacturing method of the present invention, in order to insert a sanitary paper bundle later, it is necessary that at least one end face side of the rectangular tubular carton is open. However, both wife side may be opened. For example, a rectangular tubular carton 100 shown in FIG. 3 is an example in which both a pair of end faces 8 are opened by bending into a shape having an upper surface 2, a bottom surface 3, and a pair of side surfaces 6.

  In the manufacturing method of the present invention, as the rectangular tubular carton, a window film that is arranged in advance so as to cover the outlet from the inside of the rectangular tubular carton and has a slit for taking out the sanitary paper. It is preferable to use one with affixed. Such a rectangular cylindrical carton has a window film attached to the inner surface thereof, so that it can be said that defective insertion of sanitary paper bundles is more likely to occur than a filmless one. Therefore, the production method of the present invention can be suitably used.

  In the production method of the present invention, the method for forming the rectangular tubular carton is not particularly limited. For example, by folding a carton blank made of paper material or the like, such as the carton blank 110 shown in FIG. Can be formed.

  The carton blank 110 has a top surface 2, a bottom surface 4, and a pair of side surfaces 6 formed of a sheet of paper material via a fold line, and an inner flap 26 is formed from the edge of the side surface 6 via a fold line. It has been extended. Further, the upper surface outer flap 28 extends from the edge of the upper surface 2 via a folding line. Similarly, the bottom surface outer flap 30 extends from the edge of the bottom surface 4 via the folding line. Has been issued. Furthermore, a side joining margin 32 extends from one side edge of the bottom surface 4 via a folding line.

  The carton blank 110 has an annular outlet forming cut line 14 formed on a surface corresponding to the upper surface of the carton body 16. If necessary, a window film in which a slit is formed may be attached to a position surrounding the outlet forming cut line 14. Such a carton blank 110 can be formed into a rectangular tubular carton in which both end faces are opened by bending each folding line and joining the side joining margin 32 and the side face 6.

[3-2] Repeated structure formation step (step B):
Then, the folded one of the plies P _n, the folded ply P _n pinching other plies P _{n + 1} during a further, by repeating the operation of folding the other plies P _{n + 1,} forming the repeating structure To do.

Such a process can be performed by a folded plate type processing machine .

  A folding plate type processing machine (also referred to as a “multiple machine”) is a processing machine provided with a long ply supply roll and a folding plate corresponding to the number of plies constituting a sanitary paper bundle, and is a long ply. A long sanitary paper bundle can be formed by pulling out a long ply from the supply roll and stacking the drawn long ply while folding it with a folding plate. A sanitary paper bundle can be formed by cutting the long sanitary paper bundle into an appropriate length.

[3-3] Folded part forming step (C step):
Further, the uppermost ply P _U is sandwiched between the ply P _U-1 positioned immediately below the ply P _U , and then folded again to form the folded portion on the upper surface side of the ply P _U-1 positioned immediately below. To obtain the sanitary paper bundle.

Formation of folds can be carried out by folding at least once more than usual ply P _U of the top layer.

In the manufacturing method of this invention , the said B process and this C process use the folding plate type processing machine provided with the elongate ply supply roll and folding plate according to the number of sets of the said ply, and from each elongate ply supply roll. the plies of long supplied, carried out by folding back by the folding plate. That is, the folding plate type machine, by adding one of the folding plate for folding the ply P _U of the top layer, it is possible to perform the step B and the step C continuously, efficient manufacturing It can be performed. This step C may be performed after the long sanitary paper bundle is cut into an appropriate length, but is preferably performed before cutting in consideration of production efficiency.

  The long sanitary paper bundle obtained as described above is cut into an appropriate length by a cutter equipped with a round blade or a band saw to obtain a sanitary paper bundle. As the cutter, for example, a multi-blade saw, a round blade saw, a table-type multi-blade saw or the like can be suitably used.

[3-4] Carton formation step (D step):
Finally, the sanitary paper bundle is housed in the internal space of the square cylindrical carton, and then the end face is formed by bending and fixing the flap, thereby obtaining a sanitary paper with a carton.

Specifically, after the sanitary paper bundle is inserted from the side of the open face of the pre-formed square tubular carton, a pair of inner flaps are bent along a folding line on one or both sides of the face. Then, the top and outer bottom flaps are folded so that they partially overlap each other, and the overlapping part is bonded and fixed with an adhesive or the like to close the opening of the rectangular tubular carton. And a pair of wife surfaces is formed. In this way, a sanitary paper with a carton can be manufactured.

The manufacturing method of sanitary paper with a carton of the present invention can be used for manufacturing sanitary paper such as paper towels such as tissue paper and kitchen paper, sheet-like toilet paper, and Watting (paper cotton). In particular, it can be suitably used for the manufacture of so-called slim type sanitary paper with a carton in which sanitary paper having the same number of plies as the conventional one is housed in the inner space of the carton that is configured thinner than the conventional product.
