Description

  The present invention relates to a sanitary paper storage carton, and more particularly to a sanitary paper storage carton that can easily peel off a window film.

  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 on the box 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 box, for example, a box in which a window film such as a polyethylene film covering the outlet is previously attached from the inside of the box 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. And the adhesion | attachment part at the time of sticking a window film on a box is arrange | positioned in the annular | circular shape which surrounds an extraction port, especially the rectangular shape which surrounds an extraction port. For example, like the sanitary paper storage carton 110 shown in FIG. 7, the bonding portion 22 is arranged in a rectangular shape surrounding the outlet, and the rectangle is configured in a shape in which a part of the short side is broken. A sanitary paper storage carton has been proposed (see, for example, Patent Document 2).

  The tissue paper stored in the box is usually a pair of two sheets, and each pair is stored by being alternately folded by a so-called pop-up method so that each set can be continuously taken out from the inside of the box. ing. Thus, when alternately folded, when one set of tissue paper is pulled out from the slit, the next set is pulled out from the inside of the box to the position held by the slit. The pulled-out tissue paper is held in a predetermined position where it pops up by the frictional force between the slit of the window film and the tissue paper, and is prevented from falling into the box. In addition, tissue paper is protected from external dust and foreign matter by a window film.

  Such a box is not limited to tissue paper, but is used to store sanitary paper that includes tissue paper (a collective term for disposable paper such as paper towels (kitchen paper, etc.), toilet paper (excluding rolls), and cotton (paper cotton)). Widely used as a box.

  By the way, the “Container Recycling Law” has been fully implemented since 1997, and it has clarified the responsibility of consumers to separate and collect waste, municipal collection, and the recycling of businesses. As a result, in recent years, the movement toward building a recycling-oriented economic society has been accelerating. As for used cartons of sanitary paper such as tissue paper and kitchen paper, consumers are required to peel off the pasted window film from the carton body, separate it, and discard it.

In view of this, various ideas have been proposed to make it easy to peel off the pasted window film from the carton body and to facilitate separation and disposal of the window film. For example, a collaborator of the present inventor has already proposed a carton in which a cut line surrounding a bonding portion of a window film is formed in the carton body (see, for example, Patent Document 3).
Japanese Utility Model Publication No.41-6464 JP-A-9-118377 JP-A-2005-313909

  The carton can expose the window film attached to the inside of the carton to the outside of the carton by incising a cut line surrounding the bonding portion of the window film. Therefore, the attached window film can be peeled off from the carton body without the need for the troublesome work of dismantling the carton's wife, putting the hand in there, and peeling the inner window film. It is possible to easily separate and discard the film.

  Thus, the carton previously disclosed by the inventor's collaborator is useful in that it makes it easy to peel off the pasted window film from the carton body and facilitates the separation and disposal of the window film. In recent years, when the movement toward the construction of a recycling-oriented economic society is proceeding at an accelerating rate, there is a demand for measures that make it easier to peel off the window film. For example, there is a strong demand for a carton that can easily peel off a window film even for a weak person such as an elderly person, a child, or a woman.

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] Carton for storing sanitary paper:
The sanitary paper storage carton of the present invention has a shape having an upper surface 2, a bottom surface 4, a pair of side surfaces 6, and a pair of wife surfaces 8, as in the sanitary paper storage carton 1 shown in FIGS. The cut-out line 14 for forming the outlet is formed so as to form a box that is bent and defined by these surfaces and has an internal space in which the sanitary paper can be stored. A window film having a formed carton body 16 and a window film 20 which is disposed so as to cover the outlet from the inside of the carton body 16 and has a slit 18 for taking out sanitary paper. 20 is affixed to the inside of the carton body 16 by the adhesive portion 22, a pair of wife surface 8 of the carton body 16, perpendicular to the formation direction of the slits 18 direction Are arranged, the adhesive portion 22 is disposed in a rectangular shape surrounding the outlet, rectangular long side is a portion disposed along the formation direction of the slit 18, at least a portion of the rectangular long side Is broken, discontinuous portions 24 (24a) are formed , and rectangular short sides are continuous .

[1-1] 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 to the eggplant, the box is formed with a cut-out line for forming an outlet so as to coincide with the outer peripheral shape of the outlet of the sanitary paper.

[1-1A] Box shape:
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. . Examples of such shapes 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 storage carton 1 shown in FIGS. 1 to 3 is an example in which the carton body 16 is configured in a rectangular parallelepiped shape having the side surface 6 side of the carton body 16 as a long side and the end surface 8 side as a short side. In addition, in these shapes, those obtained by chamfering the ridge line portions of the two surfaces are also included in the “box shape” referred to in this specification.

  The “carton body” is formed into a shape having a top surface, a bottom surface, a pair of side surfaces, and a pair of wife surfaces, for example, by bending a carton blank made of a paper material or the like. The carton blank 100 shown in FIG. 4 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 from the edge of the side surface 6 via a fold line. The inner flap 26 is extended.

  Further, an upper outer flap 28 extends from the edge of the upper surface 2 via a fold line, and similarly, an outer bottom flap 30 extends from the edge of the bottom surface 4 via a fold line. Has been issued. Further, a side joining margin 32 is extended from one side edge of the bottom surface 4 via a fold line, and the end face of the bottom surface outer flap 30 has a mating surface which is a joining margin with the upper surface outer flap 28. A joint 34 is attached. Such a carton blank 100 forms a pair of end faces 8 by bending each fold line, joining the side joining margin 32 and the side face 6, and joining the end face joining margin 34 and the upper outer flap 28. be able to. By carrying out like this, the carton blank 100 can be made into the sanitary paper storage carton 1 as shown in FIGS.

  In the sanitary paper storage carton of the present invention, the carton body is formed on the bottom surface, and two points a and b on a ridge line between the bottom surface and one side surface (hereinafter referred to as “bottom surface-side surface ridge line”). A first incision line for connecting the bottom surface and the side surface ridge line and / or one side surface, and starting from two points a and b, the bottom surface side surface ridge line end point or the ridge line between the top surface and the side surface ( Hereinafter, it is preferable that the first cutting line for dismantling reaching “upper surface-side surface ridge line” 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. Combined with the effect that “the carton can be easily disassembled” and the effect of “the window film is easy to peel off” of the sanitary paper storage carton of the present invention, the carton is disassembled and the window film is pulled. A series of operations of peeling off becomes easier and simpler. Therefore, such a carton contributes to promoting the separation and disposal of the sanitary paper storage carton.

  For example, the sanitary paper storage carton 1 shown in FIG. 1 to FIG. 3 is formed with the carton body 16 on the bottom surface 4 and a first incision line for connecting the two points a and b on the bottom surface-side edge line 36. 38 and the first dismantling cut line 44 that is formed on the bottom surface-side ridge line 36, has two points a and b, and reaches the end point 40 of the bottom surface-side surface ridge line 36. It is.

  Further, the sanitary paper storage carton of the present invention further includes an upper surface outer flap that extends from the edge of the upper surface via a ridge line, and a bottom surface outer flap that extends from the edge of the bottom surface via the ridge line. The upper surface outer flap and the bottom surface outer flap are joined to form a wife surface, and the bottom surface outer flap is provided with a joint allowance with the upper surface outer flap at the tip, and the joint margin and the bottom surface outer flap are A second cutting line for dismantling is formed between the second cutting line formed on the bottom surface and connecting two points on the ridgeline between the bottom surface and the one end surface, and a flap outside the bottom surface It is further preferable that a third dismantling cut line that is formed at the two points and reaches the second dismantling cut line 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. Therefore, the carton can be further easily disassembled and developed into a planar shape, and the carton can be easily dismantled even by an elderly person or a disabled person. That is, in combination with the structure of the joint portion of the sanitary paper storage carton according to the present invention, the window film can be more easily peeled off, and the paper and plastic can be separated and discarded more easily. .

  For example, the sanitary paper storage carton 1 shown in FIGS. 1 to 3 is extended from the edge of the upper surface 2 through the ridge line and from the edge of the bottom surface 4 through the ridge line. And an outer bottom surface flap 30. The bottom surface outer flap 30 is provided with a mating surface joint allowance 34 which is a joint allowance with the upper surface outer flap 28 at the tip, and the upper surface outer flap 28 and the bottom surface outer flap 30 are joined via the wife surface joint allowance 34. Thus, the end face 8 is formed, and a second dismantling cut line 46 is formed between the end face joining margin 34 and the outer bottom flap 30. Further, the carton body 16 is formed on the bottom surface 4, and has 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 outer flap 30. This is an example in which a third dismantling cut line 50 that is formed and starts from two points c and d and reaches the second dismantling cut line 46 is formed.

  The sanitary paper storage carton 1 shown in FIGS. 1 to 3 can be disassembled by the method shown in FIGS. First, as shown in FIG. 5, when the inner portion of the second push-in cutting line 48 is pressed and broken with the thumb, the third break-up cutting line 50 and the second dismantling cut-out 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 storage carton 1 is developed in a flat shape as shown in FIG. Can be dismantled to state. In this state, the window film 20 can be peeled off very easily.

  In the sanitary paper storage carton of the present invention, an internal space defined by an upper surface, a bottom surface, a pair of side surfaces, and a pair of wife surfaces is formed. This internal space is a space for storing sanitary paper. There are no particular restrictions on the type of sanitary paper stored in this internal space. For example, tissue paper (what is called facial paper, decorative paper, etc.), dust paper, paper towels (kitchen paper, etc.), toilet paper (excluding rolls), Disposable paper such as Watting (paper cotton) (for example, see Paper and Pulp Technology Handbook 5th Edition, page 459, issued on January 30, 1992, edited and published by the Pulp and Paper Technology Association).

  Among them, one sanitary paper is folded and folded while the other sanitary paper is sandwiched between the folded parts, so that a bundle of sanitary paper in which a plurality of sanitary papers are continuously stacked is stored in the internal space. It is preferable to do. 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 outlet, and the sanitary paper can be easily taken out. There is an advantage (so-called pop-up method).

  There is no particular limitation on the material constituting the sanitary paper storage carton of the present invention. 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.

[1-1B] Cut-out line for forming an outlet:
The “takeout forming cut line” is a cut line formed so as to coincide with the outer peripheral shape of the sanitary paper takeout opening. The user can form the outlet by breaking the cut line, and can take out the sanitary paper from the outlet.

  There is no restriction | limiting in particular about the outer periphery shape of the taking-out opening of a sanitary paper, What is necessary is just to select suitably according to the shape of a carton main body or a sanitary paper. However, since a rectangular parallelepiped is often used as the carton body, the shape of the outlet is preferably a horizontally long shape along the longitudinal direction of the carton body. Accordingly, examples of the outer peripheral shape of the outlet include a substantially rectangular shape, a substantially oval shape, an oval shape, a rhombus shape, and a polygonal shape. For example, the sanitary paper storage carton 1 shown in FIGS. 1 to 3 is an example in which a substantially rectangular outlet forming cut line 14 is formed.

  The cut line for forming the outlet is usually formed on the upper surface 2 of the carton body 16 like the sanitary paper storage carton 1 shown in FIGS. is not. For example, it may be formed on the bottom surface of the carton body, or may be formed on another surface. Moreover, the cut line for forming the outlet does not have to be formed only on one surface, and may be formed on two or more surfaces (for example, an upper surface and a bottom surface).

  In addition, the cut line for peeling may be formed in the part (part used as a cut piece) enclosed by the cut line for opening formation so that two points of the cut line for outlet formation may be connected. By forming such a cut line, there is an advantage that the cut piece can be easily peeled off. For example, in the sanitary paper storage carton 1 shown in FIGS. 1 to 3, a substantially U-shaped tearing cut line 52 is formed on the end side of the substantially rectangular outlet forming cut line 14. It is an example.

  The above-described cut line for outlet and peel-off line may be a straight cut (slit) or may be a perforation having a partial connection. In addition, a break line for opening, which is called a zipper in the packaging industry, is bent into a bowl shape (see page 281 of the packaging industry well-known and commonly used technology, issued on December 20, 1978), 2 A perforated line may be used. For example, the sanitary paper storage carton 1 shown in FIG. 1 to FIG. 3 is an example in which the portion inside the tear-out cut line 52 of the cut-out forming line 14 is a double line perforation. .

  Moreover, in the sanitary paper storage carton of the present invention, it is also one of preferable modes to form a push-up piece forming cut line for forming a pair of push-up pieces on the bottom surface. When the remaining amount of sanitary paper stored in the carton body is low, the push-up piece forming cut line formed on the bottom surface is pressed and broken, and folded inside the carton body to remove the pair of push-up pieces. Form. 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 outlet on the top surface to the last sheet of sanitary paper. For example, the sanitary paper storage carton 1 shown in FIGS. 1 to 3 is an example in which a pair of U-shaped push-up piece forming cut lines 54 are formed at the center of the bottom surface 4.

[1-2] Window film:
The “window film” is a film material that is disposed so as to cover the take-out port from the inside of the carton body and in which a slit for taking out sanitary paper is formed. When a window film is pasted from the inside of the outlet, the sanitary paper can be protected from external dust and foreign matter. Also, when taking out sanitary paper, the pop-up sanitary paper is prevented from falling into the carton due to friction between the slits formed in the window film, and the sanitary paper is kept protruding from the outlet. It becomes possible to do.

[1-2A] Film:
A “film” is a thin film member. The constituent materials are not particularly limited, but for example, plastics such as polyethylene, polypropylene, polyvinyl chloride, polyester, polyvinyl alcohol; printing paper such as glassine paper, kraft paper, Kent paper, India paper, calligraphy paper, wrapping paper, processed base paper And the like can be suitably used. Further, as the plastic, a biodegradable plastic may be used.

  The “biodegradable plastic” means a plastic that is decomposed by the action of microorganisms including bacteria or enzymes. Specifically, poly (α-hydroxy acid) such as polyglycolic acid and polylactic acid; polylactones such as poly (ε-caprolactone) and poly (β-prochiolactone); poly-3-hydroxypropionate, Poly-3-hydroxybutyrate, poly-3-hydroxycaprolate, poly-3-hydroxyheptanoate, poly-3-hydroxyoctanoate, poly-3-hydroxyvalerate, poly-4-hydroxybutyrate Poly (α-hydroxyalkanoate) such as polyethylene oxalate, polyethylene succinate, polyethylene adipate, polyethylene azelate, polybutylene oxalate, polybutylene succinate, polybutylene adipate, polybutylene sebacate, polyhexamethylene seba Kate, polyneopentylo Polycondensate of glycol and carboxylic acid such as Sareto; and the like. The polymer constituting these plastics is not limited to a homopolymer and may be a copolymer. Moreover, the polymer which has a urethane bond, an amide bond, an ether bond, etc. may be used in the range which does not affect biodegradability.

  The film includes any of a transparent film, a translucent film, an opaque film, and a colored film. Moreover, the film on which the character, the pattern, etc. were printed may be sufficient. The shape of the film may be any shape as long as the outlet of the carton body can be covered. 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 storage carton 1 shown in FIGS.

  Furthermore, in the sanitary paper storage carton of the present invention, the window film is configured in a rectangular shape, and has a higher tensile strength in the long side direction than the tensile strength in the short side direction, It is preferable that the short side is attached to the inside of the carton body so that the short side is along the wife surface and the long side is along the side surface.

  For example, in a stretched film obtained by stretching a plastic made of a linear polymer such as polyethylene or polypropylene in a certain direction, the molecular chain is oriented in the stretching direction of the linear polymer, so that the tensile strength in the stretching direction is increased. When such a stretched film is used for a window film, the window film 20 is formed in a rectangular shape like the sanitary paper storage carton 1 shown in FIGS. , And the inner side of the carton body 16 so that the long side is along the side surface 6, the window film 20 is peeled off from the one face 8 side toward the other face 8, thereby It becomes possible to peel off neatly without breaking 20 in the middle.

[1-2B] Slit:
A “slit” is a break through the window film. Sanitary paper such as tissue paper stored in the sanitary paper storage carton is drawn out of the carton through this slit. For example, the sanitary paper storage 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.

[1-3] Bonding part:
The “adhesion part” is a part that adheres the carton body and the window film. That is, the window film is affixed to the inside of the carton body by the adhesive portion. As long as a window film can be affixed on a carton main body, the formation method is not specifically limited. For example, the adhesive portion can be formed by a method such as an adhesive, a double-sided tape, and heat fusion. In addition, the adhesion part may be colored. For example, by forming a bonded portion using a colored adhesive or the like, there is an advantage that the position of the bonded portion can be easily visually recognized and the manufacture of the carton is facilitated.

  Further, in the sanitary paper storage carton of the present invention, it is necessary that the adhesive portion is disposed in an annular shape surrounding the outlet. The term “annular” as used herein means a shape in which lines are continuously connected so as to divide a certain region, and not only a shape in which one curve is continuously connected but also several straight lines. Includes continuously connected shapes. Specific examples include a substantially rectangular shape, a substantially oval shape, an oval shape, a rectangular shape, a rhombus shape, and a polygonal shape. For example, the sanitary paper storage carton 1 shown in FIGS. 1 to 3 is an example in which the adhesive portion 22 is arranged in a rectangular shape surrounding the outlet.

Further, in the sanitary paper storage carton of the present invention, the adhesive portion is arranged in a rectangular shape surrounding the outlet, and the long side of the rectangle is a portion arranged along the slit forming direction. It is necessary that at least a part of the side is broken, a discontinuous part is formed, and the rectangular short side is continuous . By adopting such a configuration, it is possible to reduce the adhesive strength of the adhesive portion by the amount of the formed discontinuous portion (to reduce the area of the adhesive portion to be peeled), so the slit formation direction (for example, The window film can be easily peeled off along the long side direction of the rectangular window film. Therefore, even a weak person such as an elderly person, a child, or a woman can easily peel off the window film from the carton body.

  On the other hand, in the conventional sanitary paper storage carton, for example, like the sanitary paper storage carton 110 shown in FIG. 7, a portion of the adhesive portion disposed along the slit forming direction is broken. In general, it was formed continuously. Therefore, when the window film 20 is peeled along the long side direction, the peeling may be difficult.

  Further, the sanitary paper storage carton of the present invention can reduce the application area of the adhesive, thereby shortening the drying time of the adhesive and reducing the amount of the adhesive used. From the viewpoint of production cost and resource saving.

  Conventionally, since it takes time for the adhesive to dry and exhibit adhesive force, there is a problem that the window film is peeled off before bonding unless the window film itself has a certain weight. On the other hand, the sanitary paper storage carton of the present invention has an advantage that the drying time of the adhesive can be shortened, so that it is not necessary to make the window film thicker than necessary to increase the weight.

  For example, in the sanitary paper storage carton 1 shown in FIGS. 1 to 3, the adhesive portion 22 is arranged in a rectangular shape surrounding the outlet, and one of the long side portions arranged along the direction in which the slit 18 is formed. This is an example in which the portion is broken and three discontinuous portions 24 (24a) are formed (6 locations in total). Further, in this example, the adhesive portion 22 has a narrow portion 56 formed narrowly at a part of a short side portion arranged in a direction orthogonal to the forming direction of the slit 18. By forming such a narrow portion 56, the adhesive strength at that portion can be reduced, so that the window film 20 is easily peeled off as compared with the case where the adhesive portion 22 is formed with a certain width. It becomes possible.

  By the way, also in the conventional sanitary paper storage carton, an example is known in which a part of the annular adhesive part is broken and the adhesive part is formed discontinuously. For example, the sanitary paper storage carton 110 shown in FIG. 7 is an example in which a part of the rectangular short side of the rectangular adhesive part 22 is broken and the adhesive part is formed discontinuously. However, this carton is formed by discontinuously forming a part of the adhesive part for the purpose of preventing a malfunction when the slit formed in the paper window film is broken from the end part. It is not intended to reduce the bonding strength of the bonded portion. Further, when the window film is peeled off, it is often peeled along the longitudinal direction of the window film (or the long side direction of the rectangle if the window film is formed in a rectangular shape). For this reason, the effect of easily peeling off the window film is exhibited only by forming the adhesive portions discontinuously along the peeling direction. That is, as in the sanitary paper storage carton 110 shown in FIG. 7, when the discontinuous portion 24 is formed in a part of the rectangular short side of the rectangular adhesive portion 22, all the annular adhesive portions are removed. Although it is possible to reduce the adhesive strength to some extent as compared with the case of continuous formation, it is difficult to easily peel off the window film like the sanitary paper storage carton of the present invention.

The sanitary paper storage cartons, among the adhesive portion, the portion located along the forming direction of the slit at least a portion of the width, the portion located along a direction perpendicular to the formation direction of the slit top It may be formed narrower than significantly. Even in such a form, similarly to the form in which a part of the adhesive portion is discontinuous, the adhesive strength at that part can be reduced. Therefore, it is possible to easily peel off the window film as compared with the case where the adhesive portion is formed with a certain width.

  Also in this form, it is necessary that the bonding portion has an annular shape that surrounds the outlet, and the same applies to a preferable annular specific example. Moreover, when making an adhesion part into the rectangular shape which surrounds an exit, it is preferable that the width | variety of at least one part of a long side of a rectangle is formed more narrowly than the maximum width of the short side of a rectangle. The “maximum width of the short side of the rectangle” is the widest width in the long side direction of the short side portion of the rectangle.

For example, sanitary paper accommodating carton 120 shown in Figure 8, the adhesive portion 22 is formed in a rectangular shape surrounding the outlet, at least a portion of the width W ₁ of the rectangular long side is a rectangular short side top it is an example that is formed narrower than the substantial W _2.

  In addition, a form in which a part of the part arranged along the slit forming direction of the adhesive part is broken to form a discontinuous part and a form in which a part of the adhesive part is formed narrow is also preferable. One of the forms. In such a form, it is possible to enjoy the effects of both a form in which a part of the adhesive part is discontinuous and a form in which a part of the adhesive part is narrowly formed, and the window film is peeled off more. It can be made easier.

  In the sanitary paper storage carton of the present invention, a portion of the adhesive portion arranged along the slit forming direction has a tapered portion in which at least one end portion is formed in a tapered shape. It is preferable. By setting it as such a structure, since an adhesion part becomes narrow as it goes to the front-end | tip of a taper part, the adhesive strength of the part can be reduced.

Moreover, sanitary paper storage carton, of the adhesive portion, it is preferable that the discontinuous portion at least part of the portion disposed along a direction perpendicular to the formation direction of the slit is broken is formed. Such a configuration can reduce the adhesive strength while ensuring the adhesive strength necessary for the short side portion, and therefore, in contrast to the configuration in which the discontinuous portion is formed in the portion arranged along the slit forming direction. As a result, the window film can be peeled off more easily.

  For example, the sanitary paper storage carton 130 shown in FIG. 9 is arranged in a rectangular shape in which the adhesive portion 22 surrounds the outlet, and a part of the long side portion arranged along the forming direction of the slit 18 is broken. The three discontinuous portions 24 (24a) are formed in each of the three locations (total of six locations), and a part of the adhesive portion 22 formed between the discontinuous portions 24 (24a) is formed in the direction in which the slits 18 are formed. This is an example in which a narrow portion 56 that is narrower than the maximum width of the short side portion arranged along the direction orthogonal to the width is formed. Further, in this example, a taper portion 25 is formed in a portion of the adhesive portion 22 arranged along the long side direction of the rectangle, and a rectangular shape arranged in a direction orthogonal to the formation direction of the slit 18. A part of the short side portion is broken to form 8 discontinuous portions 24 (24b) in total (16 locations in total).

[2] Manufacturing method:
The sanitary paper storage carton of the present invention can be manufactured, for example, by the following manufacturing method. First, a pressing die having a convex surface that matches the shape of the bonded portion is prepared. Next, after the adhesive is attached to the convex surface of the pressing die, the pressing die is brought into contact with the position surrounding the cut line for forming the outlet of the carton blank, and the adhesive is attached to the carton blank. Further, before the adhesive is dried, a window film in which slits are formed in advance is placed at a predetermined position and attached.

  Thereafter, the carton blank is bent along the folding line, the side surface and the bottom surface are joined together, and the overlapping portion is bonded with an adhesive to form a square tube shape with the end face side open. Next, a purified paper bundle in which sanitary paper is laminated is loaded into the internal space of the rectangular tubular carton blank. Further, after bending the pair of inner flaps along the folding line, the upper surface outer flap and the bottom outer flap are folded so that the portions overlap each other, and the overlapping portions are bonded with an adhesive or the like, so that the pair of wife Form a surface. In this manner, the sanitary paper storage carton of the present invention can be manufactured.

  The sanitary paper storage carton of the present invention can be suitably used as a carton for storing sanitary paper such as paper towels such as tissue paper and kitchen paper, sheet-like toilet paper, and cotton (paper cotton).
