Description

  The present invention relates to a packaging box for sanitary paper such as tissue paper. In particular, the present invention relates to a sanitary paper packaging box excellent in dismantling property that can be easily separated into paper and plastic film and discarded after peeling off the plastic film attached to the outlet.

In the tissue paper packaging box, a plastic film such as a polyethylene film is usually attached to the inner surface of a take-out port formed on the upper surface of a rectangular packaging box.
In recent years, household waste such as tissue paper packaging boxes such as tissue paper has become necessary to separate paper and packaging plastic films due to increased efforts to reduce waste and recycling containers and packaging. It is desired that the attached plastic film is peeled off after use, separated into paper and plastic film and discarded. In other words, consumers are increasingly required to dispose of different materials.
However, in order to dispose of the packaging box as paper waste or to recycle it, you must peel off the adhesive parts on the front and rear end faces of the packaging box, then put your hands into the cylindrical box and peel off the plastic film. I had to. However, the cylindrical packaging box is difficult to access and the work of peeling the plastic film affixed to the inside of the box is cumbersome. Therefore, many packaging boxes are often discarded as they are without peeling off the plastic film.

On the other hand, for tissue paper packaging boxes, paper and plastic films can be easily separated and disposed of on top of the packaging box top plate, etc. Have also been proposed in which a perforation for separation that can be cut together is provided (see Patent Documents 1 to 3).
However, in the case of providing a perforation for separation in which the conventional plastic film and the top plate can be cut together, the dismantling of the packaging box and the separation work of the paper and the plastic film must be performed separately. It was troublesome.
In addition, as described below, the arrangement of the perforation for separation lacks consideration for the case where the elderly, the disabled, etc. disassemble the packaging box and separate the paper and the plastic film. That is, for example, unlike elderly people, elderly people often have poor eyes and inconvenience, so such elderly people can easily distinguish the perforation for separation provided to separate part of the top plate of the packaging box. There are things that cannot be done. In addition, the elderly are generally not dexterous and may have weak fingers. The perforating separation perforation provided on the top plate of the packaging box requires considerable force to cut or is troublesome and very troublesome, so it may be thrown away without separation. . As described above, the separation and disposal of the paper and the plastic film in the packaging box provided with the window-attached plastic film is practically difficult for the elderly and the disabled.
Even if the top plate is separated, and then the plastic film attached to the back of the top plate is peeled off, it will still require dismantling work to crush the packaging box, so even ordinary people will throw it away. There is a problem that there are many.

A preferred sanitary paper packaging box of the present invention typically has a sanitary paper outlet formed on the top surface of the box by a cut line such as a perforation. Sanitary paper stored inside is tissue paper, paper towels (including kitchen towels, kitchen sheets, paper used mainly in kitchens), toilet paper (excluding rolls), and Watting (Paper cotton) and other disposable papers (see Paper Pulp Technology Handbook 5th edition, page 459, issued January 30, 1992, edited and published by the Paper Pulp Technology Association). In the present invention, the term sanitary paper is used as a general term for these disposable papers. In general, the phrase “tissue paper” is often used as a phrase that refers to general disposable paper such as toilet paper, but in a narrow sense, it is called facial paper, decorative paper, etc. This is a sanitary paper. The “paper towel” is a paper manufactured using pulp fiber as a main raw material as a substitute for a towel and a towel, and among these, a paper mainly used in a kitchen is referred to as a kitchen paper.

The box used in the present invention is a box formed mainly of paperboard and corrugated cardboard made of wood pulp, waste paper, etc., and the left and right sides at both ends in the longitudinal direction of the box having a substantially rectangular tube shape. Inner flaps are connected to the edge of the face plate so that they can be bent, and upper and lower outer flaps are connected to the edges of the upper and lower face plates so that they can be bent, and one of the upper and lower outer flaps is connected to the tip of each other. It is formed so as to provide a joining allowance for overlapping and adhering the parts, and is formed on the boundary between the outer flap connected to either the lower surface plate or the upper surface side and the joining allowance provided on the front end side of the outer flap. It is possible to cut the lower surface side outer flap or the upper surface side outer flap along two parallel score lines leading to the score line, and the outer flap that forms two parallel score lines is a score Inside the outer flap that does not form a line It keyed in a carton to form a wife surface of both longitudinal ends.
Hereinafter, embodiments of the present invention will be described with reference to the drawings, but the present invention is not limited thereto.

FIG. 1 is an example of an embodiment of the present invention, and FIG. 1 to FIG. 4 are perspective views showing a state in which a used packaging box is flattened from a square box shape and disassembled. 1 shows the bottom side by turning the box upside down. FIG. 4 shows a state after the box is disassembled, and shows a state in which the plastic film F is attached to the inner surface of the tissue paper take-out port. FIG. 5 is a development view of the packaging box. The packaging box of the present invention forms a carton blank in which a cardboard blank is formed by punching cardboard into a required unfolded shape and is easily bent when used, or a cut line that is easily cut when used. Use assembled in shape.
<Composition of carton blank>

First, the overall configuration will be described with reference to the developed view of FIG. Reference numerals 1 and 2 are a wide rectangular upper surface plate and a lower surface plate, and 3 and 4 are a pair of side plates forming left and right side walls having a narrow rectangular shape, which are alternately connected via a broken line. Has been. Reference numeral 5 denotes a joining piece connected to one side edge of the lower surface plate 2. The upper surface plate 1 and the lower surface plate 2 and the side surface plates 3 and 4 can be assembled into a rectangular tube shape by the joining piece 5.
Reference numerals 6 and 7 denote an upper surface side outer flap and a lower surface side outer flap connected to the upper surface plate 1, the lower surface plate 2, and both end edges, and 8 and 9 are inner surfaces connected to both end edges of the side surface plates 3 and 4. It is a flap. When the box is assembled by a sack machine, the outer flaps 6 and 7 are folded on the outer surfaces of the inner flaps 8 and 9 to seal the opening surfaces (face surfaces) of the main body. A cut line 14 is formed on the tip end side of the flap, and a joining margin 10 is connected to the outside of the cut line 14. The front end portions of the outer flaps 6 and 7 are overlapped and bonded to each other via a joint margin 10. The length of the upper surface side outer flap 6 is set to be slightly larger than half of the box height, and the length of the lower surface side outer flap 7 is also set to be slightly larger than half of the box height. The joining margin 10 connected to the tip is formed with a pair of notch steps 11a and 11b at both ends thereof, so that the joining margin is shaped like a tongue. The width of the tongue-shaped joint allowance 10 is larger than the distance between the front edges of the opposing inner flaps 8 and 9 when the inner surfaces of the upper and lower outer flaps 6 and 7 are bonded to the outer surfaces of the left and right inner flaps, respectively. Is formed.

With this configuration, after applying an adhesive to the inner surface of the upper surface side outer flap 6, the overlapping portions of the upper and lower outer flaps 6, 7 and the left and right inner flaps 8, 9 are joined via the adhesive, It is possible to close the end walls (wife surfaces) at both ends in the longitudinal direction.
The joint allowance 10 means an adhesive portion delimited by a cut line 14 at the tip of the outer flap 7, and the cut line 14 is one of the outer flaps connected to either the lower surface plate 2 or the upper surface plate 1. Only provided.
<Dismantling mechanism>

Next, the disassembly mechanism will be described.
As shown in FIG. 5, a cut line 14 is formed on the boundary between the lower side outer flap 7 and the tongue-shaped joint margin 10 connected to the tip of the flap. The lower surface plate 2 is provided with an arc-shaped cut line 12 a starting from a connecting broken line between the lower surface side outer flap 7 and the lower surface plate 2. Furthermore, starting from the intersection of the connecting broken line and the arcuate cut line 12a, two cut lines 14 formed on the boundary between the lower outer flap 7 and the joint margin 10 connected to the tip thereof are provided. Parallel cut lines 13a and 13b are formed.
Here, the arc of the “arc-shaped cut line” does not have to be a complete arc, and may be an arc collapsed into an ellipse. Further, it may be a polygonal shape such as a corner, but it is preferably a circular arc having no corners in consideration of ease of manufacturing and safety in use. The term “cut line” means a line that is easily cut off during use, and the line may be formed by a straight cut (slit) or a perforated cut having a partial connection. The interval between the cuts may be uniform or non-uniform. Further, an opening cutting line in which a cut called “zipper” in the packaging industry is bent into a bowl shape may be used. The diameter of the arc is 10 to 35 mm, preferably about 20 mm, considering that the thumb is pushed in.
As shown in FIG. 5, with respect to the lower surface plate 2, the two lower points a and b on the connecting fold line (on the side of the boundary) between the lower surface plate 2 and one side surface plate 3 are separated from each other. A pushing cut line 15 having a substantially arc shape connecting the points is formed. Also, dismantling cut lines 16a and 16b are formed from each of the starting points a and b to the end of the continuous bent line of the outer flap 7 on the bottom plate side, thereby disassembling the box after use and disposal of the box The box body can be covered as shown in FIG. 4 along the cutting lines 16a and 16b for cutting and the cutting line 15 for pushing in a substantially arc shape.
Note that the arc of the substantially arc-shaped push-in cutting line 15 does not have to be a smooth arc, and may be a triangle or a polygon. However, in consideration of ease of manufacturing and safety in use, It is preferable that it is an arc which does not have.

  Next, a method for peeling off the plastic film F attached to the inner surface of the take-out port after use will be described. First, from the state shown in FIG. 1, when the inner portion of the arcuate cut line 12a on the bottom surface is pressed with a thumb, the bottom side outer flap 7 is pushed open as shown by the arrow in FIG. The lower outer flap 7 is moved along two parallel cut lines 13a and 13b extending to the cut line 14 formed on the boundary between the side outer flap 7 and the tongue-shaped joint margin 10 connected to the tip. Can be cut. Subsequently, since the cut line 14 provided on the boundary between the lower surface side outer flap 7 and the tongue-shaped joint margin 10 connected to the tip thereof can be cut off, the lower surface side outer flap 7 and the upper surface as shown in FIG. The adhesion part of the side outer flap 6 is cut off. Further, the outer flap 6 bonded to the inner flaps 8 and 9 is also peeled off simultaneously through the notch step portions 11a and 11b provided at both ends of the tongue-like joint allowance 10, and as a result, the lower surface side outer flap is removed. 7, the upper surface side outer flap 6 and the inner flaps 8, 9 naturally expand (deploy) outward. See FIG.

Subsequently, when the inner side of the pushing line 15 having a substantially arcuate shape is pressed with a thumb or the like, the breaking lines 16a and 16b for breaking up to the ends of the continuous folding lines of the outer flap 7 are pushed and broken. As described above, the side plate 3 or 4 falls to the outside. Therefore, thereafter, the plastic film F on the back surface of the take-out port can be easily peeled off simply by spreading the whole as shown in FIG. 4, and the box can be flattened and discarded.
In addition, the person with a disorder | damage | failure in the motor function of a finger | toe may perform said disassembly work and separation of the plastic film F using a toe.

In the above embodiment, as part of the disassembly mechanism, the disassembly cut lines 16a and 16b are connected to the outer flap on the lower surface plate side along the connecting fold line between the joining piece 5 and the lower surface plate 2 from the starting points a and b. However, the present invention is not limited to this, and other configurations may be employed.
For example, as shown in FIG. 7, the cutting lines 16a and 16b for dismantling are formed from the starting points a and b to the intermediate portion along the connecting broken line between the joining piece 5 and the bottom plate 2, and the joining pieces 5 and the lower surface plate 2 are formed in the middle of the side plate 3 by forming dismantling cut lines 16c and 16d extending from the middle part of the connecting broken line to the tip of the joining piece 5 continuously from the dismantling cutting lines 16a and 16b. In the assembled state of the box, the dismantling cut lines 16e and 16f reaching the connecting broken line between the side surface plate 3 and the upper surface plate 1 may be formed in succession to the dismantling cutting lines 16c and 16d. In this case, the inside of the push-in cutting line 15 is pressed inward of the box to break the dismantling cut lines 16a and 16b, and then the portion surrounded by the cutting-in cutting line 15 is moved to the side of the box. If the cutting line 16c, 16d, 16e, 16f for demolition is pushed and broken, the portion surrounded by the cutting line 15 for pushing and the cutting lines 16a, 16b, 16c, 16d, 16e, 16f for demolition, that is, the side A part of the face plate 3 falls to the outside as shown in FIG. Then, after a part of the side plate 3 is tilted outward, the portion between the connecting broken line between the side plate 3 and the inner flap 8 and the dismantling cut line 16e is picked and pulled out in the direction of arrow A in FIG. Then, it is peeled off from the joining piece 5, and a portion between the connecting broken line between the side plate 3 and the inner flap 8 and the disassembling cut line 16 f is picked and pulled out in the direction of arrow A in FIG. If it does, the part between the connection broken line of the side plate 3 and the inner flap 8 and the cutting line 16e for disassembly and the inner flap 8 will fall outside. Thereby, like the above-mentioned embodiment, the whole can be expanded and the plastic film F on the back side of the take-out port can be easily peeled, and the box can be flattened and discarded.

  In this embodiment, in particular, the interval B1 between the connecting broken line between the side plate 3 and the inner flap 8 and the cutting line 16e for disassembling, and the connecting bent line between the side plate 3 and the inner flap 8 and the cutting for cutting. It is preferable to form the cutting lines 16e and 16f for dismantling so that the distance B1 between the line 16f is 60 to 150% of the width B2 of the inner flap 8. When the interval B1 is less than 60% of the width B2, the portion between the connecting broken line of the side plate 3 and the inner flap 8 and the cutting line 16e for disassembly or the connecting bent line of the side plate 3 and the inner flap 8 and dismantling When the portion between the cutting line 16f is picked, pulled in the direction of arrow A in FIG. 8 and peeled off from the joining piece 5, the connecting broken line between the side plate 3 and the inner flap 8 and the cutting line 16e for disassembly It becomes difficult to pick a portion between the side plate 3 or the connecting broken line between the side plate 3 and the inner flap 8 and the dismantling cut line 16f. Further, when the interval B1 exceeds 150% of the width B2, a portion between the connecting broken line between the side plate 3 and the inner flap 8 and the cutting line 16e for dismantling or the connecting bent line between the side plate 3 and the inner flap 8 The adhesive force between the part between the dismantling cut line 16f and the joining piece 5 increases, and the part between the connecting broken line between the side plate 3 and the inner flap 8 and the dismantling cut line 16e or the side plate 3 The part between the connecting broken line between the inner flap 8 and the dismantling cut line 16 f is difficult to peel off from the joining piece 5. In particular, in the configuration in which an adhesive is applied to the outer surface of the inner flap 8 over the entire surface and the outer flaps 6 and 7 are bonded to the inner flap 8, the connection folding line between the side plate 3 and the inner flap 8 By picking a portion between the dismantling cut line 16e or a portion between the side plate 3 and the inner folding line 8 and the dismantling cut line 16f, and pulling it in the direction of arrow A in FIG. Since these portions need not only be peeled off from the joining piece 5 but also the inner flap 8 needs to be peeled off from the outer flap 6, if the distance B1 exceeds 150% of the width B2, the side plate 3 and the inner flap 8 The inner flap 8 is peeled off from the joint piece 5 at the same time as the portion between the connecting broken line and the dismantling cut line 16e or the portion between the connecting bent line between the side plate 3 and the inner flap 8 and the disassembling cutting line 16f is peeled off. Can be peeled off from the outer flap 6 It becomes difficult and the dismantling workability decreases.

Next, a third embodiment of the disassembly mechanism will be described. FIG. 9 is a development view of the third embodiment. In the drawing, the same reference numerals as those in the above embodiment are the same parts, and different points are dismantling cut lines that reach the tip of the joining piece 5 continuously from the starting points a and b of the pushing cut lines 15. 16g, 16h, and the connecting folding line of the side plate 3 and the top plate 1, the side plate 3 and the inner flap 8 in succession to the cutting lines 16g and 16h for disassembly in the middle of the side plate 3 in the assembled state of the box This is the point at which the dismantling cut lines 16i and 16j that reach the intersection with the connecting broken line are formed. That is, in the second embodiment, a part of the side plate 3 is cut in a straight line, whereas in the third embodiment, a part of the side plate 3 is cut in a C shape. Of course, the dismantling cut lines 16g, 16h, 16i, and 16j do not have to be strictly symmetrical. Then, at the time of disassembly, as in the first embodiment, the inner portion of the arcuate cut line 12a is pressed and broken, and then the lower surface side outer flap 7 is pushed open to open the lower surface side outer flap 7 and the upper surface side. When the outer flap 6 and the inner flaps 8 and 9 are spread outward, and then the inner portion of the push-in cutting line 15 is pressed to break through the dismantling cut lines 16g, 16h, 16i, and 16j, the side plate 3 A part of this is incised into a C-shape and falls outwards so that the whole can be deployed. Thereby, like the said embodiment, the whole can be expanded and the plastic film F of a back surface of a taking-out port can be easily peeled, and a box can be made flat and discarded.
<Tissue paper outlet and push-up mechanism>

Next, the tissue paper push-out piece provided on the tissue paper outlet and the bottom surface of the box will be described.
The tissue paper outlet 20 shown in FIG. 5 is elongated in the longitudinal direction at the center of the top plate 1. The take-out port 20 connects two perforated opening cut lines (double sewing line) 21 spaced at a predetermined interval in the longitudinal direction of the top plate, and both ends of the cut line 21. It is surrounded by the end cut line 22.
Further, a ruled line portion surrounded by a rectangular broken line 30 is provided at a substantially central portion in the longitudinal direction of the lower surface plate 2, and a pair of broken lines 30a and 30b formed in the ruled line portion are symmetrically sandwiched between the broken lines. A pair of sanitary paper push-up pieces 33a and 33b surrounded by arc-shaped cut lines 31a and 31b to be provided are provided. The one set of push-up pieces 33a and 33b can be bent inward by the fold lines 31a and 31b, respectively, and can be used by being bent inside the box. Incidentally, the cuts of the arc-shaped cut lines 31a and 31b are perforated cuts that are partially connected even if they are formed by straight cuts (slits) as in the case of the arc-shaped cut lines 12a. But you can. The interval between the cuts may be uniform or non-uniform. Further, an opening cutting line in which a cut called “zipper” in the packaging industry is bent into a bowl shape may be used. Considering that the thumb is pushed in, the diameter of the arc is 10 to 35 mm, preferably about 20 mm. When the push-up pieces 33a and 33b break the joint of the arc-shaped cut lines 31a and 31b and bend the folding line 30a or 30b to the inner side of the box at an appropriate angle, the push-up pieces 33a and 33b Push up the tissue paper inside. As a result, the tissue paper can be popped up stably from the tissue paper outlet 20 on the upper surface to the last piece of tissue paper. In addition, it is possible to bend the inside of the box at the same time left and right by a one-push operation by making a finger enter the lift pieces 33a and 33b formed symmetrically.
FIG. 6 shows a modification of the push-up piece. In either case, it is only necessary to push the left and right push-up pieces 33a and 33b into the inside of the box. In use, a carton can be suspended from a wall or the like by hooking an S-shaped hook or the like into a hole in a push-up piece opened on the bottom surface.
