By comprising in this way, the cutting line 6 for dismantling can be favorably fractured with less force and without deviating from the cutting line 6 for dismantling.

  The sanitary paper storage carton 100 shown in FIG. 1 to FIG. 6 has an outer flap (for example, FIG. 1) overlapped on the front side of the upper surface side outer flap 11 and the bottom surface side outer flap 12 constituting the end face 4. In FIG. 6, the dismantling cut line 6 is formed on the upper surface side outer flap 11 and the bottom surface side outer flap 12 in FIG. 6, but the outer flap (for example, the bottom surface in FIG. 1) The dismantling cut line 6 may be formed in the outer side flap 12, and in FIG. 6, the upper surface side outer flap 11).

  The joining portion 7 between the upper surface side outer flap 11 and the bottom surface side outer flap 12 is configured by joining with a conventionally known adhesive or the like.

  The cutting line 6 for dismantling may be formed by a straight cut (slit) or a perforation having a partial connection, and the cut called a zipper in the packaging industry has a bowl shape. It may be a bent breaking line for opening (see page 281 of the well-known and commonly used techniques in the packaging industry, issued on December 20, 1978) or a double perforation.

  In the sanitary paper storage carton 100 according to the present embodiment, although not particularly limited, the front-side outer flap 11 or the bottom-side outer flap 12 further includes a protruding protrusion 9 for joining, It is preferable that the upper surface side outer flap 11 and the bottom surface side outer flap 12 are joined to each other at the protruding portion 9. By configuring in this way, it is not necessary to join the entire tip portion of the upper surface side outer flap 11 and the bottom surface side outer flap 12, and the joint portion 7 between the upper surface side outer flap 11 and the bottom surface side outer flap 12 is formed. Can be reduced.

Further, the sanitary paper storage carton 100 according to the present embodiment extends from both end edges of each of the pair of side faces 3a and 3b and extends from opposite side faces (for example, from both end edges of the side face 3a). In this case, the inner flap 16 is further bent on the side surface 3b side, and the inner flap 16 and the upper surface side outer flap 11 and the bottom surface side outer flap 12 are arranged so as to overlap each other in an unjoined state. The

  With this configuration, the structural strength of the sanitary paper storage carton 100 can be improved without impairing the ease of dismantling of the sanitary paper storage carton 100, and the gap between the end face 4 and the side face 3 can be improved. It is possible to effectively prevent dust and the like from entering.

  The sanitary paper storage carton 100 according to the present embodiment is a storage box mainly made of paper materials such as cardboard made of wood pulp and waste paper, and mainly contains sanitary paper 107 such as tissue paper and paper towels. A storage box for storing.

  In FIG. 2, the shape of the outlet cutting line 15 on the upper surface 1 is substantially oval. However, the shape of the outlet cutting line 15 is not particularly limited, and has a conventionally known shape. A take-out cutting line 15 may be formed.

  For example, as other shapes of the cutout line 15 for the outlet, the center is constricted, and the “bow tie” shape or the bone shape (the center portion is narrow and the end portion is rounded) is widened toward both longitudinal ends of the upper surface 1. Swelled bone shape).

  Further, the take-out cutting line 15 may be formed with a tearing-out cutting line 17 so that a portion surrounded by the taking-out cutting line 15 can be easily peeled off. For example, in the sanitary paper storage carton 100 shown in FIGS. 1 and 2, the area surrounded by the outlet cutting line 15 on the upper surface 1 is divided into two areas near the central portion. A tearing line 17 for peeling is formed for division.

  The outlet cut line 15 and the tearing cut line 17 may be formed by straight cuts (slits) or may be partially perforated, and may be used in the packaging industry. Rupture line for unsealing, which is called a zipper and bent in a bowl shape (see page 281 of the packaging industry well-known and commonly used technology, issued by the Japan Patent Office on December 20, 1978), and a double-line sewing machine Eyes may be used.

  In the sanitary paper storage carton 100 of the present embodiment, a film (not shown) such as a polyethylene film covering the outlet 10 is attached to the inner surface of the outlet 10, and a straight line is formed at the center of the film. It may be provided with a slit, or may be a so-called filmless carton having a structure in which no film is attached to the inner surface of the outlet 10.

  In addition, the carton having a film (not shown) attached to the inner surface of the outlet 10 can protect the contents against external dust and foreign matters, and when taking out the sanitary paper sheet 107 to the outside. The so-called pop-up sanitary paper sheet 107 is prevented from falling into the box due to friction between slits provided in a film (not shown), and the sanitary paper sheet 107 is held well at the outlet 10. be able to.

  On the other hand, the filmless carton can omit the material cost of a film such as a polyethylene film and the step of attaching the film, and separate and discard the film when the used sanitary paper storage carton 100 is discarded. It has the advantage that it is not necessary.

  In addition, as shown in FIGS. 1 to 3, in the sanitary paper storage carton 100 of the present embodiment, a push rule 18 may be formed on the outer periphery of the outlet 10. By configuring in this way, the structural strength around the take-out port 10 can be improved to prevent damage such as tearing, and even if the production speed is increased, the carton 100 is hardly deformed and productivity can be improved. . Further, when the sanitary paper 107 is stored and used, distortion of the carton 100 is suppressed by the crease 18, and the shape loss of the carton 100 can be well prevented. Further, when the sanitary paper 107 is taken out from the outlet 10, it is possible to reduce the sound generated when the inner peripheral edge and the sanitary paper 107 are rubbed.

  The shape of the stamped rule 18 is not particularly limited as long as it can obtain the above effects. In addition, the method for forming the stamped rule 18 includes, for example, a method in which the carton paper constituting the sanitary paper storage carton 100 is pressed by a push blade or the like, or in a punching process using a normal punching die. Examples of the method include a method in which a sheet is sandwiched between an iron plate provided with a female mold such as a hardened paper and a metal ruled line plate, and then pressed.

  Further, in the sanitary paper storage carton 100 of the present embodiment, although not particularly limited, a bottom raising portion 33 for pushing the sanitary paper 107 to the outlet 10 side is provided on the bottom surface 2 facing the top surface 1. A bottom-up part cut line 31 for forming may be formed.

  The bottom-up portion 33 is, for example, broken into a substantially semicircular shape by breaking a substantially arc-shaped cut line 31 for the bottom-up portion and using a broken line 32 provided corresponding to the substantially arc-shaped chord portion as a hinge portion. It can be formed by bending the part inward. In FIG. 2, a pair of portions divided into two substantially semicircles constitute a bottom raising portion 33.

  By forming such a raised portion 33, the sanitary paper 107 can be pushed up toward the outlet 10 when the remaining amount of the sanitary paper 107 is reduced, and the last one of the sanitary paper 107 can be reliably taken out. Is possible.

  Moreover, although illustration is abbreviate | omitted, the cut line (cutting line for outlets) for forming the outlet different from an upper surface may be formed in the bottom face, for example.

  The sanitary paper 107 stored in the space 5 in the sanitary paper storage carton 100 of the present embodiment is not particularly limited. For example, tissue paper (what is called face paper, decorative paper, etc.), dust paper, paper towel (Kitchen paper, etc.), toilet paper (excluding rolls), disposable papers such as Watting (paper cotton), etc. (see, for example, Paper Pulp Technology Handbook 5th Edition, page 459, issued on January 30, 1992, paper pulp) (Technical Association edited and published).

  As the sanitary paper 107, it is preferable that the sanitary paper 107 can be stored in the space 5 inside the sanitary paper storage carton 100 so that a part of the sanitary paper 107 is alternately folded. Such sanitary paper 107 can be continuously and smoothly taken out from the outlet 10 of the sanitary paper storage carton 100.

  Here, a method of using the sanitary paper storage carton 100 according to the present embodiment in which such sanitary paper 107 is stored will be described. When using the sanitary paper storage carton 100 of the present embodiment, first, the center portion of the outlet cut line 15 on the upper surface 1 is pressed with a finger to break the tearing cut line 17. Then, a finger is pointed into the inside of the box from this central portion, and one half of the portion surrounded by the cutout line 15 is picked up, and the takeout port 10 is opened in half.

  Next, the remaining half of the portion surrounded by the outlet cut line 15 is peeled off, and the outlet 10 is completely opened.

  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 a part of the sanitary paper 107 is stored so as to be alternately folded, when the first sanitary paper 107 is taken out, the next sanitary paper 107 that is alternately folded is pulled out. Thus, the sanitary paper 107 can be continuously taken out.
