Description

  TECHNICAL FIELD The present invention relates to a sanitary paper storage carton, and more particularly, a sanitary paper storage carton having a flap that can prevent sanitary paper from dropping by protruding to an outlet and retaining the pulled out sanitary paper. About.

  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 out a perforation (cutting line for forming an outlet) of a predetermined shape provided on one side of the box (usually the upper surface of the box), thereby taking out the elongated outlet on 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. In order to reduce the labor of sorting and discarding window film, so-called “film-less cartons” that do not use window film have been proposed (for example, Patent Documents 2 to 4).

  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. For example, in the case of a box having a window film, the pulled-out tissue paper is held in a predetermined position popped up by a 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 boxes are not limited to tissue paper, but sanitary paper containing tissue paper (generic name for disposable paper such as paper towels (kitchen paper), toilet paper (excluding rolls), and Watting (paper cotton)). Widely used as a storage box.

  By the way, the above-mentioned box is not always used with the take-out port facing upward. For example, when the box is placed in a horizontally long shape (side-down) with the side face down, the take-out port faces sideways. It may be used in the state where In such a case, for example, there is a problem that it becomes difficult to quickly pull out tissue paper.

  In order to solve the above-mentioned problem, there is known one in which the outlet of the box is arranged at a biased position rather than the center of the surface where the outlet is formed. For example, the present inventor arranges an outlet forming cut line for forming the outlet at a position biased from the center of the surface on which the outlet is formed to one side of the side surface or one side of the end face. Proposed a box (for example, Patent Document 5).

Japanese Utility Model Publication No.41-6464 JP-A-9-150871 JP 2004-262490 A JP 2005-225562 A Utility Model Registration No. 3116098

  The box described in Patent Document 5 is advantageous in that it does not select the place where the box is placed. In other words, sanitary paper can be taken out from the outlet that is offset from the center of either the top or bottom surface, so that the side of the box can be placed horizontally (sideways), or the box can be like a stand. Can be placed vertically (vertically). There is also an advantage that tissue paper can be taken out quickly even if small items are placed in the empty space on the top surface of the box. Furthermore, compared with the conventional carton containing sanitary paper, the position of the outlet is different and gives a novel impression, so there is also an advantage that consumers' willingness to purchase is enhanced. However, the box described in Patent Document 5 has room for improvement in that the tissue paper pulled out may fall into the box when placed horizontally or vertically. In this way, if tissue paper falls into the box, the finger must be put inside the box to find the tissue paper and then pulled out again, and the user is forced to perform complicated work. There was room.

  The present invention has been made in view of such problems of the prior art, and it is effective that sanitary paper that has been drawn out falls into the carton even when it is placed horizontally or vertically. It is an object of the present invention to provide a carton for storing sanitary paper that can be prevented.

  As a result of intensive studies to solve the above-mentioned problems, the present inventor has formed a flap capable of preventing sanitary paper from falling by protruding to the outlet and engaging the pulled out sanitary paper. It has been found that the above problems can be solved, and the present invention has been completed. That is, according to the present invention, the following sanitary paper storage carton is provided.

  The sanitary paper storage carton of the present invention can effectively prevent the drawn sanitary paper from falling into the carton even when it is placed horizontally or vertically. Further, since the empty space on the surface where the outlet is formed is wide, this space can be used effectively.

  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] Carton for storing sanitary paper:
The sanitary paper storage carton of the present invention is folded into a shape having an upper surface, a bottom surface, a pair of side surfaces, and a pair of wives, as in the sanitary paper storage carton 1 shown in FIG. A carton body having a substantially rectangular parallelepiped box shape in which an internal space capable of storing sanitary paper is formed, and an outlet forming cut line for forming an outlet for the sanitary paper is formed; A sanitary paper storage carton comprising a window film disposed so as to cover the take-out port from the inside of the carton body and having a slit for taking out the sanitary paper. At least one of the cutting lines for use is formed in an annular shape that coincides with the outer peripheral shape of the outlet, and the annular cutting line is biased toward one of the wife surfaces on the outlet forming surface of the carton. And a part of the annular cut line is formed so as to be depressed toward the center of the outlet, and the indented portion projects toward the center of the outlet. The flap is formed.

[1-1] Cut-out line for forming an outlet:
The “take-out forming cut line” is a cut line provided to form a sanitary paper take-out opening, at least one of which is formed in an annular shape matching the outer peripheral shape of the take-out opening, The annular cut line is arranged at a position biased to one of the wives on the exit forming surface of the carton, and a part of the annular cut line is depressed toward the center of the take-out port. It is necessary to be configured such that a flap protruding toward the center of the outlet is formed by the indented portion (indented portion). 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.

  The outlet forming cut line needs to be formed in an annular shape that matches the outer peripheral shape of the outlet. There is no particular limitation on the cut line for forming the outlet as long as it is formed in an annular shape that matches the outer peripheral shape of the outlet. The “annular” here means a shape in which several lines (cuts) are continuously connected so as to partition a certain region. Moreover, since a rectangular parallelepiped thing is often used as a carton main body, it is preferable that the shape of the outlet is a horizontally long ring shape along the longitudinal direction of the carton main body. Accordingly, as the outer peripheral shape of the outlet, for example, a substantially semi-elliptical shape (substantially U-shaped), a semi-circular shape, a substantially rectangular shape, a substantially oval shape, a substantially oval shape, a rhombus shape, a polygonal shape, etc. Can be mentioned. For example, the sanitary paper storage carton 1 shown in FIG. 1 is an example in which a substantially oval shaped outlet forming cut line 14 is formed so as to coincide with the outer peripheral shape of the outlet.

  The annular cut line is formed so that a part thereof is depressed toward the center of the outlet, and the indented portion (indented portion) projects toward the center of the outlet. It needs to be configured so that a flap is formed. The invaginated portion is not particularly limited as long as it is configured as described above, and is, for example, substantially semi-elliptical (substantially U-shaped), semi-circular, substantially semi-elliptical, semi-elliptical, substantially rectangular, Or shapes, such as polygonal shape, can be mentioned. For example, the sanitary paper storage carton 1 shown in FIG. 1 is formed so that a part of the substantially oval-shaped takeout forming cut line 14 is recessed toward the center of the takeout opening. In this example, the flap 17 projecting toward the center of the outlet is formed in a substantially semi-elliptical shape by the portion (the indented portion 15).

  However, it is preferable that the sanitary paper storage carton of the present invention is formed so that the indented portion is indented in the slit film forming direction. That is, it is preferable that the formed flap is formed so as to protrude in the slit forming direction by forming the outlet by breaking the annular cut line. With such a configuration, after the sanitary paper is pulled out through the slit, the frictional force with the slit is not enough to hold the sanitary paper, and when the sanitary paper is about to fall into the carton, the flap further contacts the sanitary paper. A frictional force is generated between them. That is, the flap serves as a wedge for the sanitary paper, and the sanitary paper can be prevented from falling into the carton. For example, the sanitary paper storage carton 1 shown in FIG. 1 is formed with an indented portion 15 so as to be recessed in the direction in which the slit 18 is formed (that is, the long side direction of the sanitary paper storage carton 1). It is an example.

  The annular cut line needs to be arranged at a position biased toward one end face side of the carton outlet forming surface. As long as it is arranged in that way, there is no particular limitation on the number and position. With such a configuration, there is an advantage that the sanitary paper can be easily pulled out from the carton even when the carton is arranged with one of the wife faces down (vertically placed). In addition, compared with the conventional sanitary paper storage carton, it gives a novel impression, and there is also an advantage that consumers' willingness to purchase is enhanced. Furthermore, since the empty space on the take-out surface is widened, there is an advantage that this space can be used effectively. Examples of the use of the empty space include printing characters and pictures. For example, the sanitary paper storage carton 1 shown in FIG. 1 is an example in which one substantially semi-elliptical outlet forming cut line 14 is arranged at a position biased toward the one face 8a side on the upper surface 2. is there.

  Further, the annular score line can be formed on the upper surface and / or the bottom surface. For example, the sanitary paper storage carton 1 shown in FIG. 1 is an example in which an annular cut line 14 is formed on the upper surface 2. When annular cut lines are formed on the upper surface and / or the bottom surface, a sanitary paper sheet in the carton is taken from the outlet when a laminated sanitary paper partly folded is disposed between the upper surface and the bottom surface. Can be pulled out continuously.

  In addition, “arranged at a position biased toward one end face” means that the center of gravity of the part surrounded by the annular cut line (the part that becomes the cut piece) is from the center of gravity of the carton outlet forming surface. , Which means that it is arranged at a position shifted to one wife face side.

  Furthermore, it is preferable that the indented portion is formed so that the direction of intrusion toward the center of the outlet is along the direction from one end face to the other end face. With this configuration, it is more effective for the sanitary paper to fall into the carton with the flap acting as a wedge, especially when the sanitary paper storage carton is placed vertically and the protruding direction of the flap is directed upward. Can be prevented.

  For example, in the sanitary paper storage carton 1 shown in FIG. 1, one substantially oval-shaped cut-out line 14 for forming an outlet is disposed at a position biased toward the one of the face surfaces 8 a on the upper surface 2. The indented portion 15 is an example formed so as to be indented from one end face 8b toward the other end face 8a. With such a configuration, when the sanitary paper storage carton is placed vertically, the flaps effectively serve as a wedge, so that sanitary paper can be effectively prevented from falling into the carton.

  Further, the sanitary paper storage carton 120 shown in FIG. 4 and the sanitary paper storage carton 130 shown in FIG. This is an example in which the indented portion 15 is formed in a direction from one end face 8a toward the other end face 8b while being disposed at a position biased toward the 8a side. With such a configuration, for example, when a carton placed vertically with the wife face 8a facing down is placed at a high position such as overhead, the sanitary paper can be easily pulled out, and the sanitary paper can be It can prevent falling into the inside.

  Further, when the sanitary paper storage carton has a rectangular parallelepiped shape, the indented portion is formed so as to intrude along the long side direction of the carton, and the slit of the window film extends in the long side direction of the carton. It is preferable to form along. In other words, it is preferable that the indentation direction of the indentation part coincides with the slit formation direction. With such a configuration, sanitary paper can be more effectively prevented from falling into the carton. In other words, when the carton is placed vertically, the slit formation direction matches the vertical direction, so that the indented part can effectively serve as a wedge even if the holding force of the sanitary paper by the slit is insufficient. it can.

  For example, the sanitary paper storage carton 1 shown in FIG. 1 is a rectangular parallelepiped carton, and the indented portion 15 is formed so as to indent toward the long side of the sanitary paper storage carton 1, and This is an example in which the slit 18 of the window film 20 is formed along the long side direction of the sanitary paper storage carton 1.

  By the way, the carton described in Patent Documents 2 to 4 is a so-called filmless carton, and a flap-like portion protruding from the long side of the rectangular outlet is formed in the filmless carton. ing. This flap-like portion can play a role of holding sanitary paper when the film-less carton take-out port is placed upward (flat). However, for example, when the carton is placed vertically, the sanitary paper drawn from the carton does not stop at any of the flap-like portions and falls into the carton. On the other hand, the sanitary paper storage carton of the present invention naturally falls out of the sanitary paper drawn into the carton due to the flap even when it is placed flat, for example, when placed vertically. This can be prevented. Further, since the indented portion is formed so as to be depressed toward the slit film forming direction, the sanitary paper is coupled with the slit for holding the sanitary paper by the frictional force with the sanitary paper. Can be effectively prevented from falling into the carton.

  In the sanitary paper storage carton of the present invention, a flap is formed by a portion surrounded by a folding line and an indented portion formed so as to connect two starting points starting to indent toward the center of the outlet. It is preferable that it is comprised. With such a configuration, if the flap is bent upward along the folding line after the outlet is formed, sanitary paper can be more effectively prevented from falling into the carton. The folding line (also referred to as “push rule”) can be formed at a desired position by press molding or the like, for example. When the carton is a rectangular parallelepiped, the folding line is preferably formed along the short side direction of the carton.

  For example, the sanitary paper storage carton 1 shown in FIG. 1 includes a folding line 19 formed so as to connect starting points (intrusion starting points) a and b where the indented portion 15 starts to intrude toward the center of the outlet. In this example, the flap 17 is formed by the portion surrounded by the indented portion 15. In this example, the folding line 19 is formed so as to be orthogonal to the slit 18 formed in the direction along the long side of the sanitary paper storage carton 1. That is, it is formed in a direction along the short side of the sanitary paper storage carton 1.

  The area of the flap is preferably 10 to 80 area%, more preferably 20 to 70 area%, and particularly preferably 30 to 60 area% of the area of the outlet. If the area of the flap is less than 10% by area of the area of the outlet, the flap serving as a wedge is too small and it may be difficult to prevent sanitary paper from falling into the carton. On the other hand, if it exceeds 80 area% of the area of the take-out port, the flap is too large and it may be difficult to pull out the sanitary paper from the carton. For example, the sanitary paper storage carton 1 shown in FIG. 1 is an example in which the area of the flap 17 is 25 area% of the area of the outlet. The sanitary paper storage carton 110 shown in FIG. 3 is an example in which the area of the flap 17 is 17 area% of the area of the outlet.

  When the sanitary paper storage carton has a rectangular parallelepiped shape, the maximum length of the outlet in the long side direction of the sanitary paper storage carton is 25 to 70% of the length of the long side of the carton. Is preferable, and it is still more preferable that it is 35 to 60%. If the maximum length is less than 25%, the take-out port becomes too small and it may be difficult to take out the sanitary paper. On the other hand, if it exceeds 70%, the outlet is too large, and the sanitary paper may easily fall into the carton. “The maximum length of the outlet in the direction of the long side of the sanitary paper storage carton” means that when the sanitary paper storage carton has a rectangular parallelepiped shape, Pass through a straight line parallel to the short side of the rectangular parallelepiped sanitary paper storage carton and the point on the annular cut line closest to the other face, and into the short side of the rectangular parallelepiped sanitary paper storage carton It means the distance from a parallel straight line.

For example, the sanitary paper storage carton 170 shown in FIG. 9 passes through a point (maximum outlet end point) c on the outlet forming cut line 14 closest to the one face 8a, and is a rectangular parallelepiped sanitary paper. a straight line X ₁ parallel to the short sides of the housing carton 170, nearest preparative point on the outlet forming score lines 14 (outlet maximum length endpoint) on the other wife surface 8b through d, rectangular sanitary the maximum length L ₁ longer side direction of the sanitary paper accommodating carton takeout distance between the straight line X ₂ parallel to the short side of the sheet storage carton, sanitary paper accommodating carton 1 in the maximum length L ₁ of an example in which the ratio of 35% of the length L ₂ of the long side.

  When the sanitary paper storage carton has a rectangular parallelepiped shape, the maximum length of the outlet in the short side direction of the sanitary paper storage carton is 20 to 80 in proportion to the length of the short side of the sanitary paper storage carton. %, Preferably 30 to 70%. If the maximum length is less than 20%, the take-out port becomes too small and it may be difficult to take out the sanitary paper. On the other hand, if it exceeds 80%, the outlet becomes too large, and the sanitary paper may easily fall into the carton. The “maximum length in the short side direction of the sanitary paper storage carton at the outlet” means that when the sanitary paper storage carton has a rectangular parallelepiped shape, the point on the annular score line closest to one side surface is A straight line parallel to the long side of the rectangular parallelepiped sanitary paper storage carton and a line parallel to the long side of the rectangular parallelepiped sanitary paper storage carton passing through the point on the annular cut line closest to the other side And distance.

For example, the sanitary paper storage carton 170 shown in FIG. 9 passes through a point (maximum outlet end point) i on the outlet forming cut line 14 closest to one side surface 6 and stores a rectangular parallelepiped sanitary paper. a straight line X ₃ parallel to the long sides of the use carton 170, nearest preparative point on the outlet forming score lines 14 (outlet maximum length endpoint) on the other side surface 6 through j, rectangular sanitary paper storage the maximum length L ₄ distance preparative short side direction of the sanitary paper accommodating carton outlet of the straight line X ₄ parallel to the long sides of the use cartons, short of sanitary paper accommodating carton 1 in the maximum length L ₄ ratio of the length L ₅ of the side is an example to be 60%.

  Further, when the sanitary paper storage carton has a rectangular parallelepiped shape, the maximum length of the flap in the long side direction of the sanitary paper storage carton is the above-described length of the sanitary paper storage carton in the long side direction of the sanitary paper storage carton. The ratio with respect to the maximum length is preferably 10 to 60%, and more preferably 20 to 50%. If the maximum length is less than 10%, the flap serving as a wedge is too small, and it may be difficult to prevent sanitary paper from falling into the carton. On the other hand, if it exceeds 60%, the flap becomes too large, and it may be difficult to take out the sanitary paper. The “maximum length in the long side direction of the sanitary paper storage carton for the flap” means that when the sanitary paper storage carton is a rectangular parallelepiped, it passes through the point on the indented portion closest to the one face. A straight line parallel to the short side of the rectangular parallelepiped sanitary paper storage carton and a straight line parallel to the short side of the rectangular parallelepiped sanitary paper storage carton passing through a point on the indented portion closest to the other face. Means distance.

For example, the sanitary paper storage carton 170 shown in FIG. 9 passes through a point e (maximum end point of the flap) e on the indented portion 15 closest to the one end surface 8a, and passes through the sanitary paper storage carton 170 having a rectangular parallelepiped shape. a straight line X ₅ parallel to the short side, passes through the closest point of the invaginated portion 15 on (maximum length endpoints flaps) f the other wife surface 8b, parallel to the short sides of the rectangular parallelepiped sanitary paper accommodating carton the maximum length L ₃ distance in the long side direction of the sanitary paper accommodating carton flaps of the straight line X _6, the maximum length of the long side direction of the sanitary paper accommodating carton takeout in the maximum length L ₃ L _{In this} example, the ratio to ₁ is 25%.

  Two annular cut lines may be formed on the outlet forming surface. By forming two, there is an advantage that the degree of freedom in placing the sanitary paper storage carton of the present invention is further increased. That is, for example, when a sanitary paper storage carton is placed vertically, any of the pair of wife faces can be used as the bottom face.

  In addition, a sanitary paper storage carton having two annular cut lines may store a stack of two sanitary papers corresponding to each outlet, or a single sanitary paper stack. May be stored so that the sanitary paper can be pulled out from any outlet.

  For example, as a sanitary paper storage carton having two annular cut lines, a substantially elliptical outlet forming cut line 14 is provided as in the sanitary paper storage carton 140 shown in FIG. The upper surface 2 is disposed at a position biased toward the one of the wife surfaces 8a, and the indented portion 15 is formed so as to indent from the wife surface 8b toward the wife surface 8a. A flap 17 is formed so as to protrude from the end face 8a toward the end face 8a, and another substantially elliptical outlet forming cut line 14 is provided on the upper face 2 on the other end. It is arranged at a position biased toward the surface 8b side, and the indented portion 15 is formed so as to indent in the direction from the wife surface 8a to the wife surface 8b, and the indented portion causes the wife surface 8a to the wife surface 8b. A flap 17 projecting in the direction of Is an example configured as. With such a configuration, it is possible to use any of the face surfaces 8a and 8b downward, so that there is an advantage that the degree of freedom in placing the sanitary paper storage carton is further increased.

  As another aspect, for example, as in the sanitary paper storage carton 150 shown in FIG. 7, one substantially oval-shaped cut-out line 14 for forming an outlet is biased toward the one face 8 a side on the upper surface 2. And the indented portion 15 is formed so as to be depressed in the direction from the wife surface 8a to the wife surface 8b, and the indented portion causes the wife surface 8a to move toward the wife surface 8b. A projecting flap 17 is formed, and another substantially elliptical outlet forming cutting line 14 is arranged at a position biased toward the other end face 8b on the upper surface 2. The indented portion 15 is formed so as to indent in the direction of the wife surface 8a from the wife surface 8b, and a flap 17 that protrudes from the wife surface 8b in the direction of the wife surface 8a is formed by the indented portion. This is an example configured as described above.

  Further, as another aspect, for example, as in the sanitary paper storage carton 160 shown in FIG. 8, one substantially elliptical outlet forming cut line 14 is formed on the one face 8 a side of the upper surface 2. The indented portion 15 is formed so as to be indented in the direction from the wife surface 8b to the wife surface 8a, and is directed in the direction from the wife surface 8b to the wife surface 8a. Further, another substantially oval shaped outlet forming cut line 14 is arranged at a position biased toward the other end face 8b in the upper surface 2. At the same time, the indented portion 15 is formed so as to indent in the direction of the wife surface 8a from the wife surface 8b, and the indented portion forms a flap 17 that protrudes from the wife surface 8b in the direction of the wife surface 8a. This is an example configured as described above.

  The cut-out 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 FIG. is not. For example, it may be formed on the bottom surface of the carton body. Further, the outlet forming cut line does not have to be formed on only one surface, and may be formed on two or more surfaces (for example, an upper surface and a bottom surface).

  Furthermore, the portion surrounded by the cut-out line for forming the outlet (the portion that becomes the cut piece) is connected to two points on the cut-out line for forming the outlet, and the portion that becomes the cut piece is divided into two parts. A tearing line for peeling may be formed. By forming such a cut line, there is an advantage that the cut piece can be easily peeled off.

  For example, the sanitary paper storage carton 1 shown in FIG. 1 connects two points (peeling cut line end points) g and h on the outlet forming cut line 14 to form a substantially elliptical shaped outlet. This is an example in which a tearing cutting line 52 for dividing a portion surrounded by the cutting line 14 (a portion to be a cut piece) into two near the center is formed.

  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.

  Further, in the sanitary paper storage carton according to the present invention, when the outlet cut line is formed on the upper surface of the sanitary paper storage carton, the push-up piece forming cut for forming a pair of push-up pieces on the bottom surface. Forming a lead wire is also a preferred form. When the remaining amount of sanitary paper stored in the carton body is reduced, a pair of push-up pieces is formed by pressing and breaking the push-up piece forming cut line formed on the bottom surface and bending it inside the carton body. 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 upper surface outlet to the last sheet of sanitary paper. For example, in the carton blank 100 shown in FIG. 2, the outlet cut line 14 is formed on the surface to be the upper surface 2, and the U-shaped push-up piece forming cut line 54 is formed at the center of the surface to be the bottom surface 4. This is an example in which one pair is formed.

[1-2] 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.

[1-2A] 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 FIG. 1 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 pair of face surfaces 8a and 8b sides as short sides. . 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.

  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. 2 has a top surface 2, a bottom surface 4, and a pair of side surfaces 6 formed by a sheet of paper material via a folding line, and from the edge of the side surface 6 via a folding line. The inner flap 26 is 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. Further, a side joining margin 32 is extended from one side edge of the bottom surface 4 via a folding line, and the end face of the bottom surface outer flap 30 has a mating surface which is a joint allowance with the upper surface outer flap 28. A joint 34 is attached. Such a carton blank 100 bends each fold line, joins the side joint allowance 32 and the side face 6, and then joins the wife face joint allowance 34 and the upper outer flap 28, so that the pair of wife faces 8 a and 8 b are joined. Can be formed. In this way, the carton blank 100 can be a sanitary paper storage carton 1 as shown in FIG.

  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, by taking out the uppermost sanitary paper, 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 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.

[1-3] 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.

[1-3A] 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 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 FIG.

[1-3B] 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. Although there is no restriction | limiting in particular as a formation direction of a slit, It is preferable to form in the direction in alignment with the long side of the sanitary paper storage carton of this invention. For example, the sanitary paper storage carton 1 shown in FIG. 1 is an example in which a linear slit 18 is formed along the long side of the sanitary paper storage carton 1 at the center of the window film 20.

  In the sanitary paper storage carton of the present invention, it is preferable that the slit of the window film is formed in the same direction as the direction in which the indented portion is indented. With such a configuration, after the sanitary paper is pulled out through the slit, the frictional force with the slit is not enough to hold the sanitary paper, and when the sanitary paper is about to fall into the carton, the flap further contacts the sanitary paper. A frictional force is generated between them. That is, the flap serves as a wedge for the sanitary paper, and the sanitary paper can be prevented from falling into the carton. For example, the sanitary paper storage carton 1 shown in FIG. 1 is an example in which the slits 18 are formed in the intrusion direction of the indented portion 15 (the direction in which the flap protrudes).

[2] Manufacturing method:
The sanitary paper storage carton of the present invention can be manufactured, for example, by the following manufacturing method. First, a carton blank in which a cut line for forming an outlet is not formed is prepared. Next, in this carton blank, a shape that is formed in an annular shape that coincides with the outer peripheral shape of the take-out port at a position that is biased to one of the wife surfaces on the upper surface, a part of which is indented toward the center of the take-out port A cut-out line for forming an outlet is formed. Subsequently, a window film in which a slit is formed in advance is disposed and pasted at a position surrounding the cut-out line for forming the outlet.

  After that, the carton blank is bent along a folding line, the side surface and the bottom surface are overlapped with each other, 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 surface outer flap are bent so that the portions overlap each other, and the overlapping portions are bonded with an adhesive or the like, thereby making a pair of wives 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).
