Description

  The present invention relates to a method for manufacturing a sanitary paper-containing carton. More specifically, the sanitary paper can be prevented from being damaged, the window film being bent, or the window film being peeled off during manufacturing. The present invention relates to a carton manufacturing method.

  In general, tissue paper widely used in homes and offices is sold in the form of being stored in the internal space of a rectangular parallelepiped box (hereinafter also referred to as “carton”). When using tissue paper, the user cuts the elongated outlet into a carton by cutting off a perforation (cutting line for forming the outlet) of a predetermined shape provided on one side of the box (usually the upper surface of the box). Can be formed.

  As such a carton, for example, a carton in which a window film such as a polyethylene film covering the outlet is previously attached from the inside of the carton and a linear slit is formed at the center of the window film is proposed. (For example, refer to Patent Document 1). The user can draw out the tissue paper stored in the internal space through the slit of the window film and use it.

  By the way, in the above carton, the adhesive part when the window film is stuck to the carton is often arranged in an annular shape surrounding the take-out port, particularly in a rectangular shape surrounding the take-out port. In addition, there are also known those in which a part thereof is broken to form a discontinuous portion (see, for example, Patent Documents 2 to 4).

  The carton described in Patent Document 2 is a carton in which a pair of short sides of a rectangular adhesive part is partially broken to form discontinuous parts. This carton is formed by extending the slit to the adhesive part in order to prevent problems such as deterioration of the appearance of the carton when the end of the slit formed in the paper window film is broken. For this reason, the pair of short sides of the rectangular adhesive portion is broken to form discontinuous portions.

  The carton described in Patent Document 3 is a carton in which a pair of opposing sides of a square-shaped adhesive portion is partially broken to form discontinuous portions. In this carton, a pair of opposing sides of a square-shaped adhesive portion is broken to form discontinuous portions for the purpose of reducing the resistance to taking out sanitary paper stored in the carton.

  The carton described in Patent Document 4 is a carton in which one short side of a rectangular adhesive part is partially broken to form a discontinuous part. In this carton, one short side of a rectangular adhesive portion is broken to form a discontinuous portion for the purpose of inserting a gift certificate between the pasted window film.

  In general, the carton first forms a rectangular tube carton in which both or one of the pair of wife surfaces are opened, and then a bundle of sanitary paper is inserted from the opened wife surface side of the square tube carton. Manufactured. However, in the carton, a discontinuous portion (non-adhesive portion) that is not attached to the carton in the attached window film may hang down inside the carton. If the non-adhesive portion of the window film hangs down inside the carton, the sanitary paper bundle sometimes gets caught on the sagging window film when the bundle of sanitary paper is inserted into the rectangular tube carton. When a bundle of sanitary paper was caught on the hanging window film, the following problems were caused.

  First, if a bundle of sanitary sheets is forcibly inserted in a state in which the bundle of sanitary sheets is caught on the hanging window film, the sanitary sheets may be damaged. In addition, the window film is bent in the insertion direction of the bundle of sanitary paper, and a part of the slit is covered with the folded window film, so that it may be difficult to take out the sanitary paper. Furthermore, if a bundle of sanitary paper is forcibly inserted, part of the window film may be peeled off, and the window film and the slit may not perform their functions.

  The present invention has been made in view of the above-described problems of the prior art, and includes a window film that is bonded by an adhesive portion that is partially broken to form a discontinuous portion. When manufacturing a carton containing sanitary paper by inserting a bunch of sanitary paper into a carton for storing a bundle (hereinafter referred to as “carton for storing sanitary paper”), sanitary paper is damaged, window film is bent, Provided is a method for producing a sanitary paper-containing carton that can prevent the window film from peeling off.

  As a result of intensive studies to solve the above-described problems, the inventors of the present invention have at least adhesive portions formed continuously when a sanitary paper bundle is inserted into the sanitary paper storage carton to produce a sanitary paper-containing carton. A square tube-shaped carton having an open end face is formed, and a sanitary paper sheet is formed from the end face of the open end face of the square tube-shaped carton where the adhesive portion is continuously formed. It has been found that the above problem can be achieved by inserting a bundle, and the present invention has been completed. That is, according to this invention, the manufacturing method of the sanitary paper containing carton shown below is provided.

  ADVANTAGE OF THE INVENTION According to this invention, the manufacturing method of the sanitary paper containing carton which can prevent that sanitary paper is damaged, a window film bends, and a window film peels can be provided.

  Hereinafter, the best mode for carrying out the present invention will be described, but the present invention is not limited to the following embodiment. That is, it is understood that modifications and improvements as appropriate to the following embodiments are also within the scope of the present invention based on ordinary knowledge of those skilled in the art without departing from the spirit of the present invention. Should be.

[1] Manufacturing method of carton with sanitary paper:
Method for producing sanitary paper carton of the present invention has an upper surface, a bottom surface, a pair of side surfaces, and a pair of his wife surface, said upper surface, outlet forming score lines of sanitary paper is formed, further wherein A window film is arranged so as to cover from the back side of the upper surface , and the window film surrounds the cut-out line for forming the outlet in a rectangular shape having a long side on the side surface and a short side on the wife surface side, and the one wife surface side. Sanitary pasted from the back side of the upper surface by an adhesive part in which the short side of the other side is continuously formed and the discontinuous part is formed on the short side of the other side and the long side of the pair of side surfaces upon producing paper carton, top, bottom, and a pair of side surfaces, is opened at least bonded portion wife surface short side which is continuously formed Rutotomoni, the outlet forming score lines The window film arranged to cover The adhesive portion by forming a square tubular carton pasted from the back side of the upper surface, of the opened wife surface of square tubular carton, the side wife face the short side of the adhesive portion is continuously formed A bundle of sanitary paper is inserted.

[1-1] Carton with sanitary paper:
Sanitary paper carton produced by the production method of sanitary paper carton of the present invention, a top surface, a bottom surface, a pair of side surfaces, and a pair of his wife surface, said upper surface, taken in the sanitary paper outlet forming notches A window film is disposed so as to cover from the back side of the upper surface , and the cut-out line for forming the outlet is surrounded by a rectangular shape having a long side on the side surface and a short side on the wife surface side, short sides wife surface side is continuously formed in, and the adhesive portion discontinuity the long sides of the short sides and a pair of side surface is formed on the other wife side, window film, wherein the upper surface It is affixed from the back side.

  Usually, a sanitary paper carton is folded into a shape having a top surface, a bottom surface, a pair of side surfaces, and a pair of wife surfaces, and is a box shape in which an internal space that can store sanitary paper is defined by these surfaces. Configured. Examples of the box shape include hexahedron shapes such as a rectangular parallelepiped shape and a cubic shape. For example, the sanitary paper-filled carton 1 shown in FIGS. 1 to 3 is configured in a rectangular parallelepiped shape having the side surface 6 side as a long side and the wife surface 8 side as a short side. In addition, these shapes may be a box shape with chamfered ridge portions of two surfaces.

The “take-out forming cut line” is a cut line that is formed on the upper surface to form a sanitary paper take-out opening. There is no restriction | limiting in particular about the shape of the cut line for taking-out opening, What is necessary is just to select suitably according to the shape of a carton or a sanitary paper. For example, the sanitary paper-filled carton 1 shown in FIGS. 1 to 3 is an example in which a substantially rectangular outlet forming cut line 14 is formed.

The “window film” is a film material that is arranged so as to cover the cut-out line for forming the outlet from the back side of the upper surface , and is formed with a slit for taking out sanitary paper. Normally, the outlet forming cut line is often formed on the upper surface of the sanitary paper-filled carton, so the window film is arranged so as to cover the outlet forming cut line from the back side of the upper surface. Often.

  The “adhesion part” is a part that surrounds the above-described cut line for forming the outlet in an annular shape and adheres the window film. That is, the sanitary paper-filled carton has a window film attached to the inside by an adhesive portion.

  “Annular” means a shape in which lines are continuously connected so as to divide a certain area, and not only a shape in which one curve is continuously connected but also a number of straight lines are continuously connected. Includes tied shapes. For example, a substantially rectangular shape, a substantially oval shape, an oval shape, a rectangular shape, a rhombus shape, a polygonal shape, and the like can be given. For example, the sanitary paper-filled carton 1 shown in FIGS. 1 to 3 is an example in which the adhesive portions 24 that annularly surround the outlet forming cut line 14 are arranged in a rectangular shape.

  In addition, the “bonding portion” is a portion in which a portion on one side of the face is continuously formed and a discontinuous portion is formed in a portion on the side of the other face. When the adhesive portion is configured in this way, the hygienic paper bundle is caught by the window film hanging down inside the carton by inserting the hygienic paper bundle from the end face on which the adhesive portion is continuously formed. Thus, it is possible to prevent sanitary paper from being damaged, the window film from being bent, and a part of the window film from being peeled off.

  Furthermore, when the adhesive part is arranged as described above, the adhesive strength of the adhesive part can be reduced by the amount of the discontinuous part (the area of the adhesive part to be peeled can be reduced), so that the window film is easily peeled off. It becomes possible. In particular, even a weak person such as an elderly person, a child, or a woman can easily remove the window film from the carton with sanitary paper.

  In particular, in the manufacturing method of the present invention, the adhesive portion for pasting the window film surrounds the cut-out line for forming the outlet in a rectangular shape having a long side on the side surface and a short side on the side of the face. It can be suitably used for the manufacture of sanitary paper-filled cartons arranged so that the short sides are continuously formed and the discontinuous portion is formed on the short side on the other end face side.

  For example, the sanitary paper-filled carton 1 shown in FIGS. 1 to 3 surrounds the outlet forming cut line 14 formed on the upper surface 2 in a rectangular shape having a long side on the side surface 6 and a short side on the end surface 8 side. This is an example in which the short side on the side of one end face 8a is continuously formed and the discontinuous portion 24a is formed on the short side on the side of the other end face 8b.

[1-2] Formation of rectangular tubular carton:
In the manufacturing method of the present invention, first, a rectangular tubular carton having an upper surface, a bottom surface, and a pair of side surfaces and at least a wife surface on the side where an adhesive portion is continuously formed is opened.

  The “rectangular cylindrical carton” refers to a cylindrical shape that is bent into a shape having an upper surface, a bottom surface, and a pair of side surfaces and is partitioned by these surfaces to form an internal space. For example, the rectangular tubular carton 101 shown in FIG. 4 is an example in which both the pair of end faces 8 are opened by bending the upper side 2, the bottom side 3, and the pair of side faces 6. That is, the square cylindrical carton refers to a shape in which the end face of the sanitary paper-filled carton is opened (the end face is not formed). In the present specification, the term “rectangular carton” is not limited to one in which both of the pair of end faces are opened, but only the end face on which the adhesive portion is continuously formed is opened. Shall also be included.

  A window film is attached to the inside of the rectangular tubular carton by the above-described adhesive portion. As long as the bonding portion is arranged in the above-described shape, there is no particular limitation on other shapes and forming methods.

  In other words, the shape of the adhesive part encircles the cut-out line for forming the outlet, the part on the one face side is continuously formed, and the discontinuous part is formed on the other face side. As long as it is a shape to be formed, there is no particular limitation, and there is no limitation on the position and number of discontinuities.

  For example, in the carton 1 with sanitary paper shown in FIGS. 1 to 3, the adhesive portion 24 has the outlet forming cut line 14 formed on the upper surface 2, the side surface 6 side being the long side and the wife surface 8 side being the short side. Surrounding in a rectangular shape, the adhesive portion 24 is continuously formed with a short side on the side of one end surface 8a, and one discontinuous portion 24a is formed on the short side on the side of the other end surface 8b, This is an example in which discontinuous portions 24a are formed at three locations (6 locations in total) on the long sides on the pair of side surfaces 6 side.

  Moreover, an adhesion part can be formed as follows, for example. First, a pressing die having a convex surface that matches the shape of the bonded portion is prepared. In this pressing die, a convex surface is arranged at a portion where the adhesive portion is continuously formed, and a concave surface is arranged at a portion where the adhesive portion is broken and a discontinuity is formed. Subsequently, after an adhesive is attached to the convex surface of the pressing die, the pressing die is brought into contact with a position surrounding the outlet forming cut line, and the adhesive is attached. Further, before the adhesive dries, a window film is placed and pasted. As described above, the adhesive portion is formed of an adhesive or the like for attaching the window film.

  The window film attached to the inside of the rectangular tube carton by the adhesive portion is not particularly limited in its constituent materials, but for example, plastic such as polyethylene, polypropylene, polyvinyl chloride, polyester, polyvinyl alcohol; glassine paper, kraft paper Printing paper such as Kent paper and India paper, paper such as calligraphy paper, wrapping paper, processed base paper, etc. can be suitably used. Further, as the plastic, a biodegradable plastic may be used.

  Further, the window film may have any shape as long as the window forming cut line can be covered from the back side of the surface on which the opening forming cut line is formed. However, since a horizontally long shape is widely used as the shape of the outlet, it is preferable to use a rectangular film like the sanitary paper-containing carton 1 shown in FIGS.

  The window film is formed with a slit which is a cut through the window film. Sanitary paper including tissue paper stored in the carton containing sanitary paper is drawn out of the carton through this slit. For example, the sanitary paper-filled carton 1 shown in FIGS. 1 to 3 is an example in which a linear slit 18 is formed at the center of the window film 20.

  Further, the window film can be provided with a peeling tab. The “tab” is a knob for peeling off the window film. By attaching such a tab, the window film can be peeled off by holding the tab. However, in the manufacturing method of the present invention, if the tab is disposed on the edge on the side where the adhesive portion is continuously formed, a bundle of sanitary paper inserted into the square cylindrical carton may be caught on the tab. is there. Therefore, there is a possibility that the same trouble as the above-mentioned trouble caused by the window film hanging down inside the carton is caused by the tab. Therefore, it is preferable that the tab is not attached to the end edge on the side where the adhesive portion is continuously formed.

  For example, the carton 110 with sanitary paper shown in FIG. 5 has a short edge on the side where the discontinuous portion 24a is formed on the side edge where the discontinuous portion 24a is formed on the bonding portion 24. This is an example in which a semicircular tab 22 is attached to the side.

  Furthermore, the marking for peeling off can also be displayed on the edge to which the said tab was attached to the said window film. The “marking” is a mark such as a character, a figure, a symbol, a pattern, or a color for indicating the direction in which the window film is peeled off or indicating the position of the edge of the window film. By this marking, the position of the edge of the window film can be easily visually confirmed.

  In the manufacturing method of the present invention, the method of forming the rectangular tubular carton is not particularly limited, but can be formed by, for example, bending a carton blank made of a paper material or the like.

  As the carton blank, for example, a carton blank 100 as shown in FIG. 6 can be used. The carton blank 100 shown in FIG. 6 has a top surface 2, a bottom surface 4, and a pair of side surfaces 6 formed of a sheet of paper via a folding line, and from the edge of the side surface 6 via the folding line. The inner flap 26 is extended.

  For example, in the rectangular tubular carton 101 shown in FIG. 4, the carton blank 100 shown in FIG. 6 is bent along a folding line, the side surface 6 and the side surface joining margin 32 of the bottom surface 4 are overlapped, and the overlapping portion is bonded with an adhesive. It is an example formed by bonding.

  In the rectangular carton formed in this way, it is necessary that the end face on the side where the adhesive portion is continuously formed is open. For example, the rectangular tubular carton 101 shown in FIG. 4 is an example in which the end face 8a on the side where the adhesive portion 24 is continuously formed is opened.

[1-3] Inserting a bundle of sanitary paper:
In the manufacturing method of the present invention, after forming the rectangular tube-shaped carton as described above, the hygiene from the side of the wife surface on the side where the bonded portion is continuously formed among the opened wife surfaces of the rectangular tube-shaped carton. Insert a stack of paper.

  In this manner, a bundle of sanitary paper is inserted into the rectangular tube carton from the side of the end face on which the adhesive portion is continuously formed, rather than the end of the end face on which the discontinuous portion is formed in the adhesive portion. By doing so, it is possible to prevent the bundle of sanitary sheets to be inserted from being caught by the window film that hangs down. And the malfunction resulting from it can be prevented.

  That is, in manufacturing a carton containing sanitary paper, it is possible to prevent the sanitary paper from being damaged by forcibly inserting the sanitary paper bundle in a state where the sanitary paper bundle is caught on the hanging window film. Further, since the window film is bent in the insertion direction of the bundle of sanitary paper and a part of the slit is covered with the folded window film, it is possible to prevent difficulty in taking out the sanitary paper. Furthermore, it is possible to prevent the window film and the slit from performing their functions by forcibly inserting a bundle of sanitary paper and peeling off a part of the window film.

  In addition, in the manufacturing method of the present invention, when inserting a bundle of sanitary paper into a rectangular tube carton, the wife surface on the side where the discontinuous portion is formed in the adhesive portion may be opened or sealed. In the case of continuously manufacturing sanitary paper-filled cartons, it is preferable that the wife surface on the side where the discontinuous portion is formed in the bonded portion is also opened.

  By the way, the conventional carton containing sanitary paper is usually formed in a rectangular parallelepiped shape, and the rectangular parallelepiped carton often has a wife face on the short side. And the adhesion part which has stuck the window film on a rectangular parallelepiped carton arrange | positions a long side on the side surface side of a carton, and a short side on the wife surface side like the carton shown in FIG. 7, FIG. Often rectangular. Such a carton is usually formed by first forming a rectangular tube carton with one of the wife surfaces open, and then inserting a bundle of sanitary paper from the opened wife surface side of the square tube carton. Manufactured. That is, in the conventional manufacturing method of sanitary paper-containing cartons, the side of the face is the side of the face where the adhesive part is continuously formed, or the side of the face of the face where the discontinuous part is formed in the adhesive part. Regardless of which, a bundle of sanitary paper was inserted.

  For example, the conventional carton 120 with sanitary paper shown in FIG. 7 encloses the outlet forming cut line 14 into a rectangular shape having a long side on the side surface 6 side and a short side on the side of the wife surface 8. Discontinuous portions 24 a are respectively formed on the short sides of the adhesive portion 24, and the end face 8 is disposed on the short side of the adhesive portion 24. In such a conventional sanitary paper-containing carton 120 shown in FIG. 7, even if a bundle of sanitary paper is inserted from any end face 8 side, there is a risk that the sanitary paper bundle may be caught on the hanging window film. Further, the sanitary paper bundle is caught on the sagging window film, so that the sanitary paper may be damaged, the window film may be bent, or the window film may be peeled off.

  Further, for example, the conventional carton 130 with sanitary paper shown in FIG. 8 surrounds the outlet forming cut line 14 in a rectangular shape having a long side on the side surface 6 side and a short side on the side surface 8 side. A short side of the surface 8a side is continuously formed, and a bonding portion 24 is formed in which a discontinuous portion 24a is formed on the short side of the other end surface 8b, and on the short side of the bonding portion 24 Wife face 8 is arranged. In such a conventional sanitary paper-containing carton 130 shown in FIG. 8, if a bundle of sanitary paper is inserted from the short-side wife surface 8 b side where the discontinuous portion 24 a is formed in the bonding portion 24, it hangs down. A bundle of sanitary paper may be caught on the window film. Therefore, there is a possibility that the same trouble as the conventional carton 120 with sanitary paper shown in FIG.

By the way, in the manufacturing method of the present invention, the window film encloses the cut-out line for forming the outlet in a rectangular shape having a long side on the side surface and a short side on the side of the face, and the short side on one side of the face is continuous. A sanitary paper-filled carton affixed from the back side of the upper surface by means of an adhesive portion formed in a discontinuous manner on the short side of the other face side and the long side of the pair of side faces. upon the upper surface, a bottom surface, and a pair of side surfaces, are arranged so as to cover at least an adhesive portion wife surface of the continuously formed short side is opened Rutotomoni, outlet forming score lines The window film forms a rectangular tube carton pasted from the back side of the upper surface by the bonding part, and the short side where the bonding part is continuously formed among the opened wife surfaces of the rectangular tube carton to insert a bunch of sanitary paper from the side of the wife surface of the side.

  For example, FIG. 4 shows an outlet forming cut line 14 formed on the upper surface 2 surrounded by a rectangular shape having a long side on the side surface 6 side and a short side on the side surface 8 side, and a short side on the side of one end surface 8a. Are formed continuously, and one discontinuous portion 24a is formed on the short side on the other end face 8b side, and further, there are three discontinuous portions 24a on the long side on the pair of side surfaces 6 side (total 6 places) The rectangular side carton 101 having the pair of end faces 8 open to which the window film 20 is pasted is formed by the formed adhesive part 24, and the short side where the adhesive part 24 is continuously formed This is an example in which a bundle of sanitary paper 103 is inserted into a rectangular tubular carton 101 from the end face 8a side.

  The sanitary paper-filled carton has been described with an example in which the rectangular adhesive portion is disposed. However, in the manufacturing method of the present invention, the window film surrounds the cut-out line for forming the outlet, Sanitary paper affixed from the back side of the surface on which the cut line for forming the outlet is formed by the adhesive part in which the part is continuously formed and the discontinuous part is formed in the part on the other face side When manufacturing a carton, a rectangular tube carton having an upper surface, a bottom surface, and a pair of side surfaces, at least a side surface on which the adhesive portion is continuously formed is opened, The same effect can be obtained as long as a bundle of sanitary sheets is inserted from the side of the face of the opened face where the adhesive portion is continuously formed.

  Note that a bundle of sanitary paper is a sanitary paper that is laminated with a plurality of sanitary papers by folding one sanitary paper and folding it with the other sanitary paper sandwiched between the folded parts. It is preferable to store the bundle in the internal space. In the sanitary paper having such a laminated structure, when the uppermost sanitary paper is taken out, a part of the sanitary paper of the next layer sandwiched between the sanitary papers protrudes from the take-out port, and the sanitary paper can be easily taken out. There is an advantage (so-called pop-up method).

  There are no particular restrictions on the type of sanitary paper. For example, tissue paper (what is called face paper, decorative paper, etc.), dust paper, paper towels (kitchen paper, etc.), toilet paper (excluding rolls), and Watting (paper cotton) And the like (for example, see Paper and Pulp Technology Handbook 5th edition, page 459, published on January 30, 1992, edited and published by the Pulp and Paper Association of Japan).

  In the manufacturing method of the present invention, after inserting a bundle of sanitary paper into the square cylindrical carton as described above, a sanitary paper carton is manufactured by forming a wife surface and closing the opening of the square cylindrical carton. be able to.

  For example, in the rectangular tubular carton 101 shown in FIG. 4, a pair of inner flaps 26 are bent along a folding line, and the upper outer flap 28 and the lower outer flap 30 are bent so that parts of them overlap each other. A pair of end faces 8 can be formed by bonding with an adhesive or the like. Note that the end face on which the discontinuous portion is formed in the adhesive portion may be formed in advance before the sanitary paper bundle is inserted into the rectangular tubular carton.

  In addition, according to the manufacturing method of the present invention, for example, the sanitary paper-filled carton 1 shown in FIGS. 1 to 3 has a top surface 2, a bottom surface 4, a pair of side surfaces 6, and a pair of wife surfaces 8, The sanitary paper outlet forming cut line 14 is formed on either side, and the outlet forming cut line 14 is covered from the back side of the surface on which the outlet forming cut line 14 is formed. The window film 20 is arranged in such a manner that the window film 20 annularly surrounds the outlet forming cut line 14, a portion on the side of one end surface 8a is formed continuously, and the other end surface 8b A sanitary paper-filled carton can be produced by attaching the discontinuous portion 24a to the side portion from the back side of the surface on which the outlet forming cut line 14 is formed.

  The sanitary paper-containing carton manufactured by the manufacturing method of the present invention will be further described with reference to the sanitary paper-containing carton 1 shown in FIGS.

  For example, the sanitary paper-filled carton 1 shown in FIGS. 1 to 3 connects the two points a and b on the bottom surface-side ridge line 36, and the first pushing cut line 38 formed on the bottom surface 4 and the bottom surface − This is an example in which a first dissection cut line 44 formed on the side ridge line 36 and starting from two points a and b and reaching the end point 40 of the bottom surface-side ridge line 36 is formed. Such a carton can be easily disassembled by separating the side surface and the bottom surface when discarding an empty carton after use.

  Also, for example, the sanitary paper-filled carton 1 shown in FIGS. 1 to 3 is provided between the end face flap 34 and the bottom face flap 30, which is a joint allowance attached to the tip of the bottom face flap 30. A dismantling cut line 46 is formed, formed on the bottom surface 4, a second pushing cut line 48 connecting the two points c and d on the ridge line between the bottom surface 4 and the one end surface 8, and the bottom surface This is an example in which a third dismantling cut line 50 formed on the outer flap 30 and starting from two points c and d and reaching the second dismantling cut line 46 is formed. Such a carton can separate not only the side surface and the bottom surface, but also the upper surface outer flap and the bottom surface outer flap forming the wife surface.

  The sanitary paper-containing carton 1 shown in FIGS. 1 to 3 can be disassembled by the method shown in FIG. First, as shown in FIG. 9, when the inner portion of the second push-in cutting line 48 is pressed and broken with the thumb, the third dismantling cut line 50 and the second dismantling cut-off line are accompanied accordingly. The cut line 46 is also broken, and the upper outer flap 28 and the lower outer flap 30 can be cut. Next, when the inner portion of the first push-in cut line 38 is pressed and broken with the thumb, the first break-up cut line 44 is also broken and the bottom surface 4 and the side surface 6 are cut. be able to. By doing so, the top outer flap 28, the bottom outer flap 30, the side surface 6 and the bottom surface 4 can be cut outward, and the sanitary paper-filled carton 1 can be disassembled in a flattened state.

  The method for producing sanitary paper-containing cartons according to the present invention is suitable as a method for producing cartons for storing sanitary paper such as paper towels such as tissue paper and kitchen paper, sheet-like toilet paper, and cotton (paper cotton). is there.
