Description

  The present invention relates to a sanitary paper-filled carton. More specifically, the present invention relates to a carton with sanitary paper that can reliably take out sanitary paper one set at a time and that can satisfactorily hold the next sanitary paper drawn out in a pop-up manner.

  Cartons containing sanitary paper such as tissue paper widely used in homes and offices generally have an outlet for taking out the tissue paper on one side of the rectangular parallelepiped box (usually the upper surface of the box). It has a structure. The user cuts off the cut piece along a perforated cut line having a predetermined shape provided on one surface of the box, forms an elongated outlet (opening), and takes out the tissue paper therefrom. Usually, a film such as a polyethylene film covering the outlet is attached to the inner surface of the outlet, and a linear slit is provided in the center of the film (see, for example, Patent Document 1). The tissue paper as the contents is drawn out through the slit of the film.

  In many cases, tissue paper is made into a set of two sheets, and the set is folded and stored alternately so that it can be continuously taken out from the inside of the carton, and when the set of tissue paper is pulled out from the slit, The next set of tissue paper is folded by a so-called pop-up method so as to be pulled out from the inside of the box to a position held by the slit. The above-mentioned film adhered to the inner surface of the box protects the contents against external dust and foreign matters, and when the tissue paper is taken out, the so-called pop-up tissue paper is caused by friction between the slits of the film. It prevents falling into the box and holds the tissue paper in place.

  On the other hand, a so-called filmless carton having a structure in which the film is not attached to the inner surface of the outlet has been proposed for the purpose of omitting the material cost of the film such as polyethylene film and the step of attaching the film to the box (for example, (See Patent Documents 2 to 4 and Non-Patent Document 1).

  Further, in such a filmless carton, the tissue paper being taken out is taken out of the outlet by opening the both ends in the longitudinal direction of the outlet, which is elongated in the longitudinal direction of the box and having a substantially rhombic shape, into a specific angular shape. There has been proposed a carton containing tissue paper that can be held at both ends so as not to drop into the box (see, for example, Patent Document 5). Furthermore, a carton has been proposed in which the shape of the take-out port is not limited to a rhombus, and slits are formed at both end edges of the take-out port so as to sandwich tissue paper (see, for example, Patent Document 6).

  Furthermore, a filmless carton is also proposed in which the cutout portion forming the outlet in the carton is arranged with an inclination angle θ with respect to the reference line in the long side direction of the surface having the outlet. (For example, refer to Patent Document 7).

The “Container Recycling Law” has been fully implemented since 1997, and the movement toward the construction of a recycling-oriented economic society has been fully implemented since 1997. In view of the acceleration, when disposing of used cartons of tissue paper, kitchen paper, etc., the plastic film adhered to the outlet must be peeled off from the carton body, separated and disposed This is a problem because it is troublesome at the time of disposal. The filmless carton can be said to solve this problem.
Japanese Utility Model Publication No.41-6464 Japanese Utility Model Publication No. 57-167080 JP-A-9-150871 Japanese Utility Model Publication No. 4-80878 Japanese Utility Model Publication No. 6-72883 Japanese Patent Laid-Open No. 9-30573 JP 2005-225563 A Oji Paper's public relations magazine “Miki no Hibiki”, Oji Paper Public Relations Office, published on June 20, 2003, summer issue, pages 25-26

  However, the conventional carton containing tissue paper sometimes pulls out tissue paper folded in a pop-up manner, and the next sanitary paper that is folded may be pulled out at the same time. There was a problem that it could be removed.

  In addition, when the tissue paper is taken out to the outside because the shape of both ends of the outlet is linear or the shape of the flap end provided at the outlet is angular, the tissue paper There is a problem that it is easy to be caught on a part or the like, and it is torn when it is pulled upward, or a pair of tissue papers cannot be taken out smoothly in a pop-up manner.

  The paper strength of tissue paper is a problem with the paper strength in the direction of pulling out the tissue paper held in the storage box, but paper strength is also related to other quality requirements of tissue paper and it is easy to change is not.

  On the other hand, in the carton shown in Patent Document 5, the opening angle at both ends in the longitudinal direction of the substantially diamond-shaped outlet is set from 60 ° to 170 °. If the opening angle is less than 60 °, tissue is used. When the paper is taken out, it is caught at the corners and it becomes difficult to tear or take out. On the other hand, when it exceeds 170 °, the gripping function is lowered, and the tissue paper tends to fall into the box.

  Further, in the case of the carton shown in Patent Document 6, since the entrance of the slit is narrow, it cannot be said that the tissue paper is easy to be taken out, and the shape of the slit is not smooth, so that the tissue paper is caught at the corner. .

  On the other hand, the filmless carton according to Non-Patent Document 1 is configured such that when the tissue paper in the box is pulled out by forming the forms at the left and right ends of the cutout portion forming the outlet with arcuate curves, It can be prevented from being broken by being caught in the corners or the like. However, if the flap part is folded and used, the tissue paper may fall into the box when used, and the tissue paper will pop up one by one. There was room for improvement in terms of continuous and smooth removal.

  The present invention has been made in view of the above-described circumstances, and it is possible to reliably take out sanitary sheets one by one and to hold the next sanitary sheet pulled out in a pop-up manner well at the outlet. It is to provide a sanitary paper carton possible. As a result of repeated research, it has been found that the above object can be achieved by the following means.

  That is, according to the present invention, the sanitary paper storage in which the cut-out portion for forming the take-out port is formed on the at least one surface of the box by the cut line arranged along the shape of the take-out port. A sanitary paper carton comprising a sanitary paper carton and a plurality of sanitary papers housed in such a manner that the sanitary paper storage cartons are alternately folded in part. The center line in the longitudinal direction of the cut portion is inclined with respect to the folding line of the sanitary paper within a range corresponding to the portion where the sanitary paper is alternately folded on the surface forming the outlet. A sanitary paper-filled carton is provided that is tilted at an angle θ.

  In the sanitary paper-containing carton of the present invention, as described above, the sanitary paper is alternately formed on the surface where the ellipse-shaped take-out port inclined at the inclination angle θ with respect to the folding line of the sanitary paper forms the take-out port. Because it is formed within the range corresponding to the folded part, when the top sanitary paper folded in the pop-up method is taken out, this sanitary paper (top sanitary paper) The next sanitary paper that has been drawn out is held by being restrained by the inner peripheral edge of one of the inclined oval-shaped outlets when it is drawn out about half. For this reason, two or more sets of sanitary sheets are not pulled out at a time, and a necessary number of sanitary sheets can be taken out from the sanitary sheet storage carton.

  In addition, since the shape of the cut-out part is an ellipse with no corners, the sanitary paper is taken out in a direction other than above the outlet, for example, in the direction of any side surface of the carton, or obliquely upward. The sanitary paper is not torn or damaged when pulled out. Of course, the sanitary paper-containing carton of the present invention has the effect that the sanitary paper can be reliably taken out one by one even when the sanitary paper is pulled out in the direction of the side surface, etc. The effect of favorably holding the sanitary paper at the outlet can be obtained.

  Moreover, since the shape of the cutout portion is a simple shape, when opening the takeout port, the cutout portion can be easily picked and opened, and delamination of the takeout port can be effectively suppressed. In addition, after opening the outlet, a finger can be easily inserted from the central portion of the outlet, and the first sheet can be reliably picked up.

  Further, by forming the cutout portion in an inclined state with respect to the folding line of the sanitary paper, the cutout portion is generally used as a “paper eye” of the paper material (also referred to as carton paper) constituting the sanitary paper storage carton. Therefore, when the cut portion is peeled off from the sanitary paper storage carton, an effect of suppressing the carton paper from being broken along the eyes of the paper can be expected.

  In the sanitary paper-filled carton according to the present embodiment, it is preferable that the half length of the entire circumference of the cut portion is shorter than the length of the folding line of the sanitary paper. By configuring in this way, the next sanitary paper drawn out by the sanitary paper can be easily suppressed by the inner peripheral edge of one end of the oval-shaped outlet, and only one set of sanitary paper is necessary for each set. Can be reliably removed. In addition, since the next sanitary paper is bent (rounded) and held so as to follow the outer peripheral shape of the outlet, the next sanitary paper drawn out about half is not deformed, and the next sanitary paper is not deformed. Paper can be pulled out easily.

  In addition, the sanitary paper-containing carton of the present invention is preferably a so-called filmless carton in which a film covering the outlet is not disposed inside the surface having the outlet. Such a configuration eliminates the need to separate the paper carton and the film at the time of disposal, and is environmentally friendly. Further, by eliminating the film, not only material costs can be saved, but the manufacturing process can be shortened, and energy saving and resource saving can be achieved.

  In the present specification, a carton is a storage box made mainly of paper materials such as cardboard made from wood pulp and waste paper, and mainly contains sanitary paper such as tissue paper and paper towels. It is a storage box. In this specification, sanitary paper refers to tissue paper (called face paper, decorative paper, etc.), dust paper, paper towels (kitchen paper, etc.), toilet paper (excluding rolls), and Watting (paper cotton). (For example, refer to the 5th edition of the Paper and Pulp Technology Handbook, page 459, published on January 30, 1992, edited and published by the Pulp and Paper Technology Association).

  In the sanitary paper-containing carton according to the present invention, the inclination angle θ formed by the center line of the cut portion and the sanitary paper folding line is −90 ° <θ ≦ −5 ° or 5 ° ≦ θ <90 °. It is preferable that -60 ° ≦ θ ≦ −5 ° or 5 ° ≦ θ ≦ 60 °. If the inclination angle θ exceeds -5 ° and less than 5 °, the inclination angle θ is too small, and the effect of inclining the take-out port becomes small. For example, it is difficult to hold the next sanitary paper drawn out. May be. On the other hand, when the inclination angle θ is −90 ° or 90 °, the take-out port is completely turned to the side, and for example, it may be difficult to take out sanitary paper.

  In the sanitary paper-filled carton of the present invention, it is preferable that a stamped line is formed so as to surround the take-out port over substantially the entire circumference away from the take-out port by a predetermined distance. By configuring in this way, it is possible to improve the structural strength around the outlet, suppress breakage such as tearing, and improve the productivity because the carton is hardly deformed even if the production speed is increased. In addition, when storing and using sanitary paper, the distortion of the carton is suppressed by the crease, and it is possible to satisfactorily prevent the carton from being deformed. In addition, it is possible to reduce the sound that is generated when the sanitary paper and the inner peripheral edge of the outlet are rubbed.

  Further, in the carton with sanitary paper of the present invention, the bottom raising portion for pushing the sanitary paper to the outlet side by folding the inside of the box on the surface opposite to the surface forming the box outlet is for the bottom raising portion. It is preferably formed by a score line. Thereby, the sanitary paper can be satisfactorily taken out to the last one.

  When such a raised portion is formed, the cut portion and the raised portion are formed so that the longitudinal center line of the cut portion intersects the longitudinal center line of the raised portion. It is preferable. By crossing the center line, the effect of pushing up and popping up the sanitary paper is increased.

  Moreover, when forming a ruled line over substantially the entire circumference away from the outlet by a predetermined distance, the ruled line may be a single one or a double or more. Note that the effect of suppressing delamination of the carton paper around the outlet and improving the mechanical strength of the sanitary paper storage carton increases in proportion to the number of formed creases. For this reason, it is preferable to determine the number of stamps so that the required characteristics can be satisfied.

  Further, such a stamped rule may be formed only on the surface forming the outlet, or may be formed from the surface forming the outlet to the side surface adjacent to this surface. In addition, when the ruled line is formed up to the side surface, the strength of the carton paper on this side surface can be improved, and the structure of the corner portion constituted by the surface forming the outlet and the adjacent side surface Since the strength can be improved, the three-dimensional distortion of the sanitary paper storage carton can be reduced.

  Furthermore, in the carton with sanitary paper of the present invention, it is preferable that a tearing line for dividing the longitudinal cut portion into two near the central portion is provided in the cut portion. By configuring in this way, it is easy to peel off the cutout portion, and it is possible to suppress delamination of the carton paper when the cutout portion is peeled off.

  The carton with sanitary paper of the present invention can reliably take out sanitary paper one by one and can hold the next sanitary paper drawn out in a pop-up manner well at the outlet. For example, if you take out the top sanitary paper that is folded in a pop-up manner as a set of two sheets, the end of the next sanitary paper drawn out by this sanitary paper is inside the outlet. Restrained by a portion of the periphery, it provides enough resistance to hold in a pop-up manner. It should be noted that the sanitary paper-containing carton of the present invention can be used in any case, even if the sanitary paper is pulled out above the sanitary paper storage carton or to the side of the sanitary paper storage carton. The paper can be held well at the outlet.

  Hereinafter, embodiments of the present invention will be described with appropriate reference to the drawings, but the present invention should not be construed as being limited thereto. Various changes, modifications, improvements, and substitutions can be added based on the knowledge of those skilled in the art without departing from the scope of the present invention. For example, the drawings show preferred embodiments of the present invention, but the present invention is not limited by the modes shown in the drawings or the information shown in the drawings. In practicing or verifying the present invention, the same means as described in this specification or equivalent means can be applied, but preferred means are those described below.

  1, 2, 3, 4, and 5 are views showing an embodiment of a sanitary paper-containing carton according to the present invention. 1 and 2 show a sanitary paper-containing carton according to the present invention, and FIG. 2 shows a state in which a bottom raising portion 23 provided on the lower surface plate 2 is bent inward. FIG. 3 is a development view of the state of the carton blank before assembling the sanitary paper storage carton of the sanitary paper containing carton shown in FIGS. 1 and 2, and FIG. 4 is an enlarged view of a circled portion A in FIG. FIG. FIG. 5 is a perspective view showing a state in which the sanitary paper-containing carton according to the present embodiment is opened.

  As shown in FIGS. 1 to 4, the sanitary paper-filled carton 100 according to the present embodiment has a cutout portion 13 along the shape of the outlet 10 to form the outlet 10 on at least one surface 1 a of the box. A sanitary paper storage carton 101 formed by the cut lines 11 disposed in a row, and a plurality of sanitary paper 107 stored in the sanitary paper storage carton 101 so that a part of the sanitary paper storage carton 101 is alternately folded. , And the cutout portion 13 has an oval shape in a range B corresponding to a portion where the sanitary paper 107 is alternately folded on the surface 1a forming the outlet 10. Further, the sanitary paper-containing carton 100 is formed in a state in which the longitudinal center line Y1 of the cutout portion 13 is inclined with respect to the fold line X1 of the sanitary paper 107.

  A sanitary paper storage carton 101 shown in FIGS. 1 to 4 is a storage box mainly made of paper materials such as cardboard made of wood pulp, waste paper, etc., and mainly sanitary tissue paper, paper towels, etc. A storage box for storing the paper 107. The sanitary paper storage carton 101 is a box formed of an upper surface plate 1, a lower surface plate 2, left and right side plates 3 and 4, and end face plates 6 and 7 constituting one end face in combination. Cutout for forming an outlet 10 on at least one surface of this box (surface 1a constituted by the upper surface plate 1 in the sanitary paper storage carton 101 of the sanitary paper-containing carton 100 of the present embodiment). The part 13 is formed by the cut line 11 disposed along the shape of the outlet 10.

  In addition, the sanitary paper storage carton 101 (hereinafter sometimes referred to as the sanitary paper storage carton) used in the sanitary paper containing carton 100 of the present embodiment has the sanitary paper 107 on the surface 1 a forming the outlet 10. Within the range B corresponding to the alternately folded portions, the center line Y1 in the longitudinal direction of the cut portion 13 is formed in a state where the inclination angle θ is inclined with respect to the folding line X1 of the sanitary paper 107. Yes. In the sanitary paper storage carton 101 shown in FIG. 3, a tearing line 14 for separating the longitudinal cut part 13 into two near the center is provided in the cut part 13. Yes.

  The sanitary paper 107 used in the sanitary paper containing carton 100 according to the present embodiment is stored in a pop-up manner so that a part of the sanitary paper storing carton 101 is alternately folded. For example, tissue paper (what is called facial paper, decorative paper, etc.), dust paper, paper towels (kitchen paper, etc.), toilet paper (excluding rolls), and disposable paper (such as paper cotton), such as paper pulp technology Handbook 5th edition, see page 459, published January 30, 1992, edited and published by the Pulp and Paper Technology Association).

  Usually, for example, when a sanitary sheet that is folded one by one or two or more as a set is pulled out, the next sanitary sheet that is folded and overlapped is pulled out to the outlet. In a conventional carton containing sanitary paper, the next sanitary paper may be completely pulled out from the outlet together with the uppermost sanitary paper, and two or more sanitary papers are drawn at the same time. There was a case.

  In the sanitary paper-containing carton 100 according to the present embodiment, when the sanitary paper 107 is pulled out from the outlet 10 of the sanitary paper storage carton 101, the sanitary paper 107 to be drawn out next is one of the oval-shaped outlets 10. For example, when the sanitary paper 107 such as tissue paper is taken out, two or more sets are not pulled out at one time because it is held down by the inner peripheral edge of one end. Further, even when the remaining number of sanitary sheets 107 is reduced, the next sanitary sheet 107 that is pulled out is favorably held at the outlet 10 by the frictional force, and the sanitary sheet 107 does not easily fall into the sanitary sheet storage carton 101. Become. In addition, when the cut-out portion 13 having the inclined shape is formed beyond the range B corresponding to the portion where the sanitary paper 107 is alternately folded on the surface 1 a forming the outlet 10, it is continuously drawn out. The next sanitary paper 107 cannot be removed at the outlet 10, and two or more sanitary papers are pulled out at the same time.

  In addition, the uniqueness of the state in which the outlet 10 is inclined at the inclination angle θ gives a unique impression to the user, and the psychological effect of increasing the consumer's purchasing motivation is exhibited.

  In the sanitary paper-containing carton 100 according to the present embodiment, even if the sanitary paper 107 is pulled out perpendicularly to the surface 1 a forming the outlet 10, Even if the sanitary paper 107 is pulled obliquely upward, the next sanitary paper 107 drawn out can be satisfactorily held at the outlet 10 in any case.

  Further, by forming the cutout portion 13 so as to be inclined with respect to the fold line X1 of the sanitary paper 107, the cutout portion 13 is generally made of a paper material (also referred to as carton paper) constituting the sanitary paper storage carton 101. It is formed to be inclined with respect to the “paper eye”, and the effect of suppressing the tearing of the carton paper along the paper eye when the cut portion 13 is peeled off from the sanitary paper storage carton 101. Can also expect.

  Here, with reference to FIGS. 6-8, the operation | movement at the time of drawing out a sanitary paper from the sanitary paper containing carton of this Embodiment is demonstrated. 6-8 is explanatory drawing which shows the operation | movement at the time of pulling out a sanitary paper from the sanitary paper containing carton of this Embodiment.

  As shown in FIG. 6, normally, when the carton 100 with sanitary paper is in use, the uppermost set of sanitary paper (hereinafter referred to as “top sanitary paper”) 107 a stands half up from the outlet 10. It is held in the state. At this time, the upper half of the top sanitary paper 107a folded in a pop-up manner exits from the outlet 10, and the inner peripheral edge of the outlet 10 on the side where the folded portion of the top sanitary paper 107a is located. 6, that is, in a state along the inner peripheral edge of the outlet 10 on the side surface 4 a side in FIG. 6.

  When the uppermost sanitary paper 107a is drawn upward, as shown in FIG. 7, the folded lower half side of the uppermost sanitary paper 107a is pulled out and at the same time the uppermost sanitary paper. A part of the upper half of the next set of sanitary paper (hereinafter referred to as “next sanitary paper”) 107b folded into 107a is pulled out. At this time, the uppermost sanitary paper 107a in the state along the outer periphery of the side surface 4a is the side where the lower end of the uppermost sanitary paper 107a is located, that is, the side surface 3a of the sanitary paper storage carton 101 in FIG. Move to the side.

  When the uppermost sanitary paper 107a is further pulled out, as shown in FIG. 8, the lower end of the uppermost sanitary paper 107a is completely separated from the take-out port 10, and the uppermost sanitary paper 107a is taken out. At this time, since the next sanitary paper 107b is held down by the end of the outlet 10 on the side surface 3a, the upper half is pulled out and held in the outlet 10.

  Since the next sanitary paper 107 drawn out about half in this way is bent (rounded) along the outer periphery on the side surface 4a side of the outlet 10, the next sanitary paper 107b is deformed. Therefore, the sanitary paper 107b can be easily pulled out at the next use.

  As described above, the sanitary paper 107 can be reliably taken out one by one from the sanitary paper-containing carton 100 according to the present embodiment.

  In addition, as shown in FIGS. 1 to 4, the sanitary paper-containing carton 100 according to the present embodiment has an oval shape with no corners. The sanitary paper 107 is not easily torn even when it is pulled out in the direction, for example, in the direction of the side surfaces 3a and 4a of the sanitary paper storage carton 101 or in the oblique direction. Further, when opening the take-out port 10, the cutout portion 13 is easy to pick and open, and delamination of the take-out port 10 can be effectively suppressed. Moreover, a finger can be easily inserted from the center part of the extraction opening 10 after opening, and the first one can be picked up reliably.

  The oval shape that is the shape of the cutout portion 13 of the sanitary paper storage carton 101 is not only a complete oval shape, but also an oval-like shape, such as an egg shape or a part of an oval shape. A shape that can be regarded as an ellipse is assumed to be included in an ellipse even for a shape that is convex or straight.

  Further, in the sanitary paper-containing carton 100 of the present embodiment, it is preferable that the half length of the entire circumference of the cutout portion 13 of the sanitary paper storage carton 101 is shorter than the length of the fold line X1 of the sanitary paper 107. With this configuration, the next sanitary paper 107b pulled out by the sanitary paper 107a that has been taken out can be easily held down by any one end side portion of the oval-shaped outlet 10 one by one. The sanitary paper 107 can be reliably taken out as much as necessary. Further, since the sanitary paper 107 held at the take-out port 10 is bent in a state along the outer periphery including the end portion of the take-out port 10, the sanitary paper 107 does not lose its shape and can be pulled out next time. .

  Moreover, the sanitary paper-containing carton 100 according to the present embodiment does not, for example, draw out the sanitary paper 107 toward the upper side of the upper surface plate. For example, as shown in FIG. Even when the sheet is pulled out to the side 4a side in FIG. 9, the next sanitary sheet 107 can be satisfactorily held. Even when the sanitary paper 107 is pulled out to the side surface 4a in this way, the sanitary paper 107 to be pulled out next is held down while being held down on the inner peripheral edge side of one end of the outlet 10, Two or more sets of sanitary paper 107 are not pulled out at once. FIG. 9 is a view showing the sanitary paper storage carton according to the present embodiment, and is a perspective view showing a use state in which the sanitary paper is pulled out to the side surface side. In FIG. 9, the same constituent elements as those in FIG.

  The cut lines 11 as shown in FIGS. 3 and 4 may be formed by straight cuts (slits) or perforations that are partially connected, and are referred to as zippers in the packaging industry. It may be a breaking line for opening (see page 281 of the well-known and commonly used techniques in the packaging industry, issued by the Japan Patent Office on December 20, 1978) or a double line perforation. The cut line 11 may be a perforated cut line or the above zipper. In order to make the cut surface smooth, the cut line 11 has a continuous cut or a discontinuous cut having a connecting portion (connecting portion) shorter than the cut size. It is good.

  Further, in the sanitary paper-containing carton 100 of the present embodiment, the inclination angle θ formed by the center line Y1 of the cut portion 13 and the fold line X1 of the sanitary paper 107 is −90 ° <θ ≦ −5 ° or 5 °. ≦ θ <90 ° is preferable, and −60 ° ≦ θ ≦ −5 ° or 5 ° ≦ θ ≦ 60 ° is more preferable. If the inclination angle θ exceeds −5 ° and is less than 5 °, the inclination angle θ is too small, and the effect of inclining the take-out port 10 is reduced. For example, the sanitary paper 107 that has been drawn out is taken out. It may be difficult to hold. On the other hand, when the inclination angle θ is −90 ° or 90 °, the take-out port 10 is completely turned to the side, and for example, it may be difficult to take out the sanitary paper 107.

  The sanitary paper storage carton 101 shown in FIG. 3 is formed such that the cut-out portion 13 is inclined in a counterclockwise inclination angle θ with respect to the fold line X1 of the sanitary paper 107. It may be formed in a state where the inclination angle θ is inclined clockwise.

  When the cutout portion 13 of the sanitary paper storage carton 101 in the sanitary paper containing carton 100 according to the present embodiment is peeled off and opened, as shown in FIG. To break the tear-off cutting line 14, point a finger into the inside of the box from this central part, pick up either one of the cut-out parts 13 halved from the top surface plate 1 of the box, One of the cutouts 13 is peeled off and half-opened. Next, the other cut-out portion 13 that has been halved is peeled off to form an outlet 10 that corresponds to the shape of the cut-out portion 13. Note that the tearing line 14 shown in FIG. 5 is for the tearing of the cut-out portion 13 along the shape of the finger to be pressed so that the center part can be easily broken when pressed. It is formed so that one side of the broken part of the line 14 is convex and the other side is concave.

  Thereafter, a finger is inserted from the formed outlet 10, and the uppermost first set of sanitary paper 107 is picked up and taken out upward. When the first set of sanitary paper 107 is taken out, the sanitary papers 107 stacked in the box are alternately folded one by one. Accordingly, the next sanitary paper 107 following this is drawn out.

  The carton 100 with sanitary paper shown in FIG. 5 is a pull for dividing the longitudinal cut portion 13 into two near the central portion so that the cut portion 13 can be divided and peeled at the substantially central portion. Since the peeling line 14 for peeling is disposed, it is easy to peel off the cut portion 13 and it is possible to satisfactorily suppress delamination when the cut portion 13 is peeled off. In addition, it is preferable that such a tearing line 14 for peeling is comprised similarly to the cutting line 11 which forms the cutting part 13. FIG.

  As described so far, the sanitary paper-filled carton 100 according to the present embodiment has the following effect due to the inclined outlet 10 formed in a predetermined range without arranging a film or the like covering the outlet 10. Since the sanitary paper 107 b can be held, the sanitary paper storage carton 101 has a so-called sanitary paper storage carton, in which a film covering the outlet 10 is not disposed inside the surface 1 a forming the outlet 10. A filmless carton is preferred.

  1 and 2 show a case where the width of the folded portion of the sanitary paper 107 is substantially the same as the width of the surface 1a forming the outlet 10, for example, FIG. As shown, the range B corresponding to the folded portion of the sanitary paper 107 is narrow (in FIG. 10, the range B corresponding to the folded portion of the sanitary paper 107 is substantially half the width of the surface 1a). In this case, the range in which the cutout portion 13 is formed is also narrowed according to the range B corresponding to the folded portion of the sanitary paper 107. As a result, even if the sanitary paper 107 is folded differently, the sanitary paper 107 in the second and subsequent sets can be effectively suppressed by the inner peripheral edge of one end of the outlet 10. Can be reliably taken out one by one. Here, FIG. 10 is a top view showing another example of the sanitary paper-filled carton according to the present embodiment. In FIG. 10, the same components as those in FIG. 1 are denoted by the same reference numerals, and description thereof is omitted.

  Further, as shown in FIG. 11, the carton 100 with sanitary paper according to the present embodiment is formed with a stamped line 15 so as to surround the outlet 10 over substantially the entire circumference away from the outlet 10 by a predetermined distance. Preferably it is. Here, FIG. 11 is a diagram showing another example of the sanitary paper-containing carton according to the present embodiment, and is a development view of the state of the carton blank before the sanitary paper storage carton is assembled. In FIG. 11, the same components as those in FIG. 3 are denoted by the same reference numerals, and the description thereof is omitted.

  By configuring in this way, the carton paper having a multilayer structure of usually about 5 layers is partially compressed, and the strength of the carton paper on which the surface 1a on which the outlet 10 is formed maintains the flat surface is improved. Thereby, generation | occurrence | production of the delamination around the taking-out port 10 can be prevented effectively, and breakage, such as a cutting | disconnection and tearing of the taking-out port 10, can be suppressed. Further, the surface 1a on which the outlet 10 is formed is less likely to be crushed or buckled. Further, at the time of production (assembly) of the sanitary paper storage carton 101, the box is hardly deformed even when the production speed is increased, and the productivity can be improved. Moreover, when using it in the state which accommodated the sanitary paper, the distortion of a carton is suppressed by a stamp, and it can prevent the shape loss of a carton favorably. Further, since the deformation of the take-out port 10 is suppressed, it is possible to reduce sound generated when the sanitary paper and the inner peripheral edge of the take-out port 10 are rubbed.

  In addition, the sanitary paper storage carton 101 shown in FIG. 11 is formed with a single ruled line 15 over substantially the entire circumference away from the outlet 10 by a predetermined distance. A double stamped line may be formed over substantially the entire circumference away from the exit by a predetermined distance. By configuring in this way, the strength against the pulling and compressing force at the outlet can be further improved, and the sanitary paper storage carton is less likely to be deformed.

  In addition, although there is no restriction | limiting in particular about the distance from the inner periphery of the taking-out port 10 to the pressing rule 15, For example, it is preferable to set it as 5-11 mm. By comprising in this way, structural strength can be improved favorably.

  Further, the sanitary paper storage carton 101 shown in FIG. 11 is formed with the pressing ruler 15 only on the surface 1a forming the outlet 10, but for example, although not shown, the outlet is formed. A pressing rule may be formed from the surface to be performed to the side surface adjacent to this surface (surfaces 3a and 4a constituted by the side plates 3 and 4 in FIG. 11). In addition, when the stamped line is formed even on the side surface, the strength of the carton paper on the side surface can be further improved, and the structural strength of the corner portion constituted by the upper surface and the side surface can be improved. Therefore, the three-dimensional distortion of the sanitary paper storage carton can be reduced.

  In the sanitary paper storage carton 101 shown in FIG. 3 and FIG. 11, a tear-off cutting line 14 is disposed at a substantially central portion of the longitudinal cut portion 13. For example, FIG. As shown in FIG. 4, the tearing wire 14 may be formed on one end side in the longitudinal direction of the cutout portion 13. In addition, there is no restriction | limiting in particular about the shape of the cut line 14 for peeling, For example, when pressing with a finger at the time of opening, a finger | toe will be pointed into the box from the fracture | ruptured part and the cut part 13 will be peeled off It is preferable that the shape be such that

  Furthermore, the sanitary paper-containing carton 100 according to the present embodiment is folded inside the box on the surface 2a opposite to the surface 1a forming the box outlet 10, that is, the surface 2a constituting the bottom plate 2. Accordingly, it is preferable that the bottom-up portion 23 that pushes up the sanitary paper 107 toward the outlet 10 is formed by the bottom-up portion cut line 21. As a result, when the remaining amount of the sanitary paper 107 housed in the sanitary paper-containing carton 100 is reduced, as shown in FIG. 4, the pair of bottom raised portions 23 provided on the lower surface plate 2 are placed inside the box. Can be folded and used.

  The bottom raised portion 23 is, for example, a portion that is broken into a substantially semicircular shape by breaking a substantially arc-shaped bottom raised portion cutting line 21 and using a broken line 22 provided corresponding to the substantially arc-shaped chord portion as a hinge portion. Can be formed by folding the inside of the box. In addition, in FIG. 3, the part divided into two substantially semicircles comprises the bottom raising part 23 as a pair. By forming the bottom-up portion 23 as described above, it is possible to stably pop up and take out the sanitary paper 107 from the upper surface outlet 10. The bottom raised portion 23 has a greater effect as described above as the height of the side surfaces 3a, 4a of the sanitary paper storage carton 101 increases, and the effect is sustained. In addition, it is preferable that the bottom raising part cutting line 21 is comprised similarly to the cutting line 11 which forms the cutting part 13. FIG.

  When the raised portion 23 is formed, as shown in FIGS. 3 and 11, the longitudinal center line Y1 of the cutout portion 13 and the longitudinal center line Y2 of the raised portion 23 intersect. In other words, it is preferable that the cut-out portion 13 and the bottom-up portion 23 are formed so that the center line Y1 and the center line Y2 are not parallel to each other. Thereby, the effect of pushing up and popping up the sanitary paper 107 is increased. For example, in FIG. 3, the center line Y2 in the longitudinal direction of the bottom raised portion 23 and the line X2 parallel to the fold line X1 are formed in parallel, but the outlet 10 is formed with an inclination angle θ inclined. Therefore, the center line Y1 in the longitudinal direction of the cut portion 13 and the center line Y2 in the longitudinal direction of the bottom raised portion 23 intersect each other.

  In particular, when the longitudinal center line Y1 of the cut-out portion 13 and the longitudinal center line Y2 of the bottom raised portion 23 intersect, the cut-out portion when viewed from above the surface 1a of the sanitary paper-containing carton 100. The absolute value of the angle (θ + φ) formed by 13 longitudinal centerlines Y1 and the longitudinal centerline Y2 of the raised portion 23 is preferably 30 ° to 150 °, and preferably 60 ° to 120 °. More preferably, the angle is 90 ° (that is, the center line Y1 and the center line Y2 are orthogonal). In this way, by taking a relatively wide angle (θ + φ) constituted by the center line Y1 and the center line Y2, the effect of pushing up the sanitary paper 107 to the upper surface side and popping it up increases.

  For this reason, for example, in the developed view as shown in FIG. 11, the inclination angle θ of the outlet 10 and the inclination angle φ of the bottom raising portion 23 are inclined in the same direction, and the center line Y1 in the longitudinal direction of the outlet And the angle (θ + φ) formed by the center line Y2 in the longitudinal direction of the bottom raised portion 23 is preferably close to 90 °.

  Further, when the carton 100 with sanitary paper is opened, the material of the carton 101 for storing sanitary paper is taken into consideration so that the cutout portion 13 is not broken or the cut portion 13 is not cut. There is a need to. In the sanitary paper-filled carton 100 of the present embodiment, it is preferable to produce the cardboard using wood pulp, waste paper, or the like as raw materials. In this case, the tear strength specified in JISP8116-2000 is 2500 to 2900 mN in the longitudinal direction, The range is preferably in the range of 3000 to 3400 mN. If the tear strength is too low, it is easy to break, and if it is more than necessary, it becomes difficult to open, which is not preferable.

  Further, although not particularly limited, in the sanitary paper-filled carton 100 of the present embodiment, the cutout portion 13 is in the range of 20 to 70% of the central portion in the long side direction of the surface forming the outlet 10. Preferably, it is formed in the range of 25 to 65%. By configuring in this way, the force to hold down both ends of the next sanitary paper becomes stronger, and the sanitary paper can be taken out more reliably one by one.

  Further, with this configuration, at least the take-out port 10 is not formed in a range of approximately 15% or more of each end portion in the long side direction of the surface 1a. Compared with a conventional sanitary paper storage carton that is formed relatively long in the direction, the structural strength of the storage box can be improved. For this reason, for example, the paper material (carton paper) for forming the sanitary paper storage carton can be thinned, and an economic effect can be expected.

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