Packaging box of roll product and package

Abstract

To prevent bending of a front surface plate of a body of a packaging box when a sheet body is pulled out from a roll product in a package of the roll product, and to suppress defective cutting of the sheet body.SOLUTION: A plurality of embossing parts 23 is provided on a front surface plate 21b of a body 21 of a packaging box 20. An embossing forms rib-like unevenness on the front surface plate 21b, thereby improving its strength. When a material of the front surface plate 21b is compressed during processing, its rigidity and strength are further improved. Even if a load is applied to the front surface plate 21b due to rubbing of a sheet body 11 against the front surface plate 21b, the front surface plate 21b is unlikely to bend and deform, and when attempting to close a lid 22, a situation in which the lid 22 and the front surface plate 21b interfere with each other and cannot be closed well, or a blade plate 22b of the lid 22 and the front surface plate 21b are unlikely to slide against each other is prevented. Since only the embossing is performed, the embossing is labor-saving and reduces a material cost compared to the case where a reinforcing plate, ribs, etc. are later attached to the front surface plate 21b.SELECTED DRAWING: Figure 1

Description

[Technical field]

[0001] The present invention relates to a packaging box for storing a roll product formed by rolling up a sheet such as aluminum foil, wrap film, or cooking sheet, and to a package for the roll product formed by storing the roll product in the packaging box. [Background technology]

[0002] 2. Description of the Related Art Roll products made by winding up a sheet such as aluminum foil or plastic wrap film are widely used. These types of roll products are distributed, displayed, and the like in a packaged state in which they are stored in a rectangular parallelepiped-shaped packaging box that is elongated in the left-right direction. As described in Patent Document 1, such a packaging box comprises a main body that opens upward and a lid that is rotatably connected to the back panel of the main body to open and close the opening of the main body, and the roll product is stored in the main body with its axis aligned with the left-right direction of the main body.

[0003] Here, the lid of the packaging box also serves as a cutter for cutting the sheet body to a predetermined length. That is, when using the sheet body, the predetermined length is pulled out from the roll product through the opening of the main body, and the lid is rotated to bring the blade at the tip into sliding contact with the front plate of the main body, whereby the sheet body is sandwiched between the main body and the lid from above and below and is simultaneously cut by the blade. The cut sheets are used for various purposes such as food packaging. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2016-030634 A Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, some of the instructions printed on the packaging box specify the direction in which the sheet body should be pulled out, such as upwards, but in actual use at home, the overwhelming majority of users pull out the sheet body by pulling it out toward the front (horizontally). However, when the sheet body is pulled out toward the front in this manner, it is likely to interfere with the front panel of the main body of the packaging box. More specifically, the sheet body rubs against the upper edge of the front panel of the main body, applying a load to the front panel in the direction in which the sheet body is pulled out, and the front panel may be deflected and deformed, bulging outward from its original position.

[0006] If the front panel of the main body becomes deformed in this way, when attempting to close the lid, the front panel and the lid may interfere with each other, making it impossible to close the lid, or even if the lid can be closed, the blade of the lid may not slide properly against the deformed front panel. This causes a problem of improper cutting, such as the sheet body tearing at an unintended position, making it impossible to cut to the desired length.

[0007] Therefore, the problem to be solved by the present invention is to prevent the front panel of the main body of the packaging box from bending when a sheet body is pulled out from the roll product, and to suppress poor cutting of the sheet body, in the case of a packaging body and packaging box for a roll product. [Means for solving the problem]

[0008] In order to solve the above-mentioned problems, a package for a roll product according to the present invention comprises a roll product formed by rolling up a sheet body, and a packaging box for storing the roll product, the packaging box comprising a bottom panel, a front panel and a back panel respectively connected to the front and rear edges of the bottom panel in a rising direction, and a right side panel and a left side panel respectively connected to the left and right edges of the bottom panel in a rising direction, the top panel being open, a main body for storing the roll product such that the axis of the roll product coincides with the left-right direction, a top panel, a front panel and a back panel connected to the front and rear edges of the top panel in a rising direction, The packaging box has a lid which comprises a blade plate connected in a downward direction to the edge of the top panel, the rear edge of which is connected to the upper edge of the back panel of the packaging box body, and which can open and close the opening of the packaging box body by rotating the entire lid, and which can cut the sheet material pulled out from the roll product to the front side through the opening of the packaging box body by sliding the blade plate against the front panel of the packaging box body when the opening is closed, and the front panel of the packaging box body is provided with a plurality of embossed portions arranged in parallel in the left-right direction.

[0009] In this way, the strength of the front panel is improved because the embossing process forms rib-like irregularities on the front panel. In addition, if the packaging box is made of paper or other materials, the material is compressed during processing, which further improves the rigidity and strength of the front panel. As a result, even if a load is applied to the front plate due to rubbing of the sheet body against the front plate, the front plate is unlikely to bend or deform, and it is possible to prevent situations in which the lid cannot be closed properly due to interference between the lid and the front plate when attempting to close the lid, or where it is difficult for the blade plate of the lid to come into sliding contact with the front plate. Since the front plate only needs to be embossed, it requires less work and material costs can be reduced compared to retrofitting a reinforcing plate, ribs, etc. to the front plate.

[0010] In the package for roll products according to the present invention, it is preferable that the plurality of embossed portions each extend in the up-down direction of the front plate.

[0011] Such a configuration exerts the same effect as a so-called vertical rib, resulting in a structure that is strong against loads in the up-down direction (vertical direction), and further preventing deflection of the front panel.

[0012] In the package for roll goods according to the present invention, it is preferable that each of the embossed portions is convex toward the rear surface of the front panel.

[0013] As a load is applied from the sheet body that is pulled out toward the front, the front panel of the main body tends to bend in a direction that bulges outward. However, if the embossed portion is convex toward the front surface of the front panel (concave toward the back surface), the front panel tends to bend starting from the embossed portion. By making the embossed portion convex toward the rear surface of the front plate, the front plate is less likely to bend when bulging outward, and deformation of the front plate can be further prevented.

[0014] In the roll product packaging of the invention, it is preferable that the multiple embossed portions each have a vertical length within the range of 6 mm to 25 mm and a horizontal width within the range of 2 mm to 30 mm, and are arranged at equal intervals across the entire horizontal area of ​​the front panel.

[0015] This configuration provides an optimum structure for preventing bending of the front panel of the main body. If the vertical length of the embossed portion is less than 6 mm and the horizontal width is less than 2 mm, the dimensions are too small and each embossed portion may not be able to sufficiently prevent sagging. If the vertical length of the embossed portion exceeds 25 mm and the horizontal width exceeds 30 mm, the dimensions are too large, making it difficult to provide a large number of embossed portions, and the combined effect of the multiple embossed portions in preventing sagging may be insufficient. Also, there is a possibility that gluing of the lid to the front panel may be hindered when the product is not in use.

[0016] In the package for roll products according to the present invention, it is preferable that the plurality of embossed portions are provided only at positions of the front plate where the blade plates overlap when the opening is closed.

[0017] In general roll product packaging, a sticker (opening strip) is attached to the lower edge of the blade plate and glued to the bottom of the front plate to prevent the lid from opening when not in use. When in use, the sticker can be cut off from the blade plate to open the package. Here, if an embossed portion is provided at the location of the front panel where the adhesive plate is attached, the unevenness can easily cause poor attachment, and there is a risk that the lid will open unintentionally during transportation of the package. By providing the embossed portion only on the upper portion of the front plate where the blade plates overlap, there is no unevenness on the lower portion of the front plate where the adhesive plate is attached, preventing poor attachment. In addition, when not in use, the unevenness of the embossed portion is hidden by the blade plates and cannot be seen from the outside, which improves appearance.

[0018] In the roll product packaging of the invention, it is preferable to adopt a configuration in which the roll product is stored in the main body of the packaging box so that the outer end of the roll is pulled out from the bottom to the top of the packaging box main body.

[0019] The roll product can be stored in one of two ways inside the main body: a bottom-out winding direction, in which the outer end of the sheet is pulled out from the bottom of the main body of the packaging box to the top, and a top-out winding direction, in which the outer end of the sheet is pulled out from the top. In the bottom-out winding direction, the sheet is more likely to rub against the front panel when pulled out, making the front panel more likely to bend and deform. Therefore, by providing an embossed portion on the front body, the effect of preventing sagging deformation is more pronounced in the case of a downward projection than in the case of an upward projection. When the roll product is stored with the bottom facing out, the ends are folded (turned back) significantly when the sheet is cut, preventing it from rewinding. This makes it easy to pinch the ends when pulling out the sheet the next time, allowing the operation to be carried out smoothly.

[0020] In the roll product packaging of the invention, it is preferable that the front plate of the main body is configured such that the deflection rate, calculated as the amount of deflection (mm) of the front plate when the sheet body is pulled out ÷ the opening width (mm) of the main body before the sheet body is pulled out × 100, is 12% or less.

[0021] The smaller the deflection rate, the smaller the deformation of the front panel, so it is preferable for the lower limit to be 0% or less. However, by keeping the deflection rate below a certain level in this manner, interference with the front panel when the lid is closed can be sufficiently prevented.

[0022] In addition, in order to solve the above-mentioned problems, the packaging box for roll products of the invention comprises a main body consisting of a bottom panel, a front panel and a back panel connected in a rising direction to the front and rear edges of the bottom panel, respectively, and a right side panel and a left side panel connected in a rising direction to the left and right edges of the bottom panel, and has an open top panel, and stores the roll product so that the axis of the roll product coincides with the left-right direction; and a lid consisting of a top panel and a blade plate connected in a hanging direction to the front edge of the top panel, the rear edge of the top panel being connected to the upper edge of the back panel of the packaging box main body, the opening of the packaging box main body can be opened and closed by rotating the entirety, and when the opening is closed, the blade plate is brought into sliding contact with the front panel of the packaging box main body to cut the sheet body pulled out from the roll product to the front side through the opening of the packaging box main body, and the front panel of the main body is provided with a plurality of embossed portions arranged side by side in the left-right direction. Effect of the Invention

[0023] Since the packaging body and packaging box for roll products according to the invention are configured as described above, bending of the front panel of the main body of the packaging box is prevented when the sheet body is pulled out from the roll product, thereby suppressing cutting defects.

[0025] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The roll product packaging 1 of the embodiment shown in Figures 1 to 3 comprises a roll product 10 made of a sheet body 11 and a packaging box 20 of the embodiment for storing it, and the packaging box 20 is equipped with a function for cutting out the sheet body 11 from the roll product 10, allowing the sheet body 11 to be smoothly cut out.

[0026] As shown in FIG. 3, the roll product 10 has an elongated cylindrical shape, and is formed by winding a sheet body 11 around a winding core 12. The type of the sheet body 11 is not particularly limited, but examples thereof include aluminum foil, wrap film, and cooking sheet. The material of the sheet body 11 is also not particularly limited, but examples thereof include metal, synthetic resin, and paper. The material of the winding core 12 is not particularly limited, and may be made of paper. The winding core 12 may be omitted, and the roll product 10 may be made of the sheet body 11 alone.

[0027] As shown in FIGS. 1 to 3, a packaging box 20 for roll products according to an embodiment has a rectangular parallelepiped shape that is elongated in the left-right direction, and is made up of a main body 21 and a lid 22. The material of the packaging box 20 is not particularly limited, and may be made of paper. The main body 21 consists of a bottom plate 21a, a front plate 21b and a back plate 21c respectively connected to the front and rear edges of the bottom plate 21a so as to rise up, and side plates 21d respectively connected to the left and right edges of the bottom plate 21a so as to rise up, and the top surface is open. The rolled product 10 is housed in the main body 21 such that its axis coincides with the left-right direction of the main body 21.

[0028] The roll product 10 is rotatable about its axis inside the main body 21, and as the roll product 10 rotates, the sheet body 11 can be pulled out through an opening in the main body 21. Here, the roll product 10 is stored in a so-called bottom-out winding direction, that is, in a winding direction in which the end portion is pulled out from the bottom side to the top side.

[0029] The left and right side panels 21d are formed with push-in pieces 21e separated by an easy-to-break line such as a perforation, and when in use, the easy-to-break line can be broken to push the push-in pieces 21e into the winding core 12 of the roll product 10. The pushing piece 21e prevents the rotating roll product 10 from jumping out of the opening of the main body 21 when the sheet body 11 is pulled out. An inner flap 21f is connected to the upper edge of each of the left and right side panels 21d. A lock piece 21g is defined by a U-shaped slit at the boundary between the inner flap 21f and the side panel 21d, and when the inner flap 21f is folded inward, the lock piece 21g is cut and raised to protrude outward.

[0030] The lid 22 is composed of a top plate 22a, a blade plate 22b connected so as to hang down from the front edge of the top plate 22a, a backing plate 22c connected to the lower edge of the blade plate 22b, and side plates 22d connected to the left and right sides of the top plate 22a. The rear edge of the top plate 22a of the lid 22 is connected to the upper edge of the back plate 21c, and is rotatable around this point.

[0031] A plurality of blades are formed on the lower edge of the blade plate 22b and are aligned in the left-right direction. The sheet body 11 is cut by these blades. An easy-to-break line such as a perforation is formed at the boundary between the adhesive plate 22c and the blade plate 22b. The adhesive plate 22c is attached to the lower surface of the front plate 21b of the main body 21. This fixes the lid 22 in a state in which the opening of the main body 21 is closed.

[0032] When using the package 1, the easy-to-break line is broken, and the adhesive plate 22c serving as the opening strip is separated from the blade plate 22b. This releases the fixation of the lid 22, and the lid 22 becomes rotatable between a closed position where the opening of the main body 21 is closed and an open position where the opening of the main body 21 is opened. First, with the lid 22 in the open position, the roll product 10 is rotated and the sheet body 11 is pulled out from the opening of the main body 21 by a desired length. Next, the cover 22 is rotated to the closed position and the blade plate 22b is lowered while being brought into sliding contact with the surface of the front plate 21b of the main body 21, whereby the sheet body 11 is sandwiched from above and below and cut by the blades of the blade plate 22b.

[0033] The lid 22 has a step 22e formed on the rear surface of each of the side plates 22d. When the cover 22 is rotated to the closed position, a lock piece 21g cut and raised from the inner flap 21f of the main body 21 fits into this step 22e. This keeps the opening of the main body 21 closed by the lid 22, preventing the lid 22 from opening unintentionally. Furthermore, the depth of step 22e is shallow, and lock piece 21g is only lightly fitted into it, so if a small amount of force is applied to rotate lid 22 to the open position, lock piece 21g will come out of step 22e and the lock will be released.

[0034] Although not particularly limited, such a packaging box 20 is produced by assembling a blank 20' shown in FIG. The blank 20' is formed by punching out a sheet such as cardboard. The blank 20' has, from the top, a front plate 21b, a bottom plate 21a, a back plate 21c, a top plate 22a, a blade plate 22b, and a pasting plate 22c, which are arranged in parallel in the vertical direction with ruled lines or easy-to-break lines interposed therebetween. By bending each line or easy-to-break portion into a rectangular cylindrical shape, as shown in FIG. 5, the trunk of main body 21 is formed from front panel 21b, bottom panel 21a, and back panel 21c, and the trunk of lid 22 is formed from top panel 22a, blade plate 22b, and attachment plate 22c.

[0035] As shown in FIG. 4, the blank 20' has side flaps 21d at the left and right edges of the front plate 21b, the bottom plate 21a, and the back plate 21c, respectively, with ruled lines interposed therebetween. The side flaps 21d are folded along the lines, overlapped, and attached to each other to form the left and right side panels 21d of the main body 21, as shown in Fig. 5. An inner flap 21f is connected to the outside of the side flaps 21d of the bottom panel 21a via lines or the like. Furthermore, the blank 20' has side flaps 22d on the left and right edges of the top plate 22a and the blade plate 22b, with creases formed therebetween. The side flaps 22d are folded along the lines, overlapped, and glued together to form the left and right side panels 22d of the lid 22, as shown in FIG. At this time, since the dimensions of the side flaps 22d of the top plate 22a and the blade plate 22b are different, the both side flaps 22d do not overlap completely, and as a result, a step 22e is formed on the rear surface of the side plate 22d.

[0036] As shown in FIGS. 1 and 3, the front plate 21b of the main body 21 is embossed to form a plurality of embossed portions 23. As shown in FIG. The multiple embossed portions 23 each have an elongated oval shape and are arranged so that their major axis direction coincides with the vertical direction of the front plate 21b of the main body 21, that is, so as to extend in the vertical direction. The embossed portions 23 are arranged in parallel along the left-right direction of the front plate 21b. In the embodiment of the present invention, the embossed portion 23 is formed by pressing the entire inner side of the solid line portion of the L-shape as shown in Figure 1 to form a concave embossment, but it may also be an embossment like a ruled line formed by pressing only the solid line portion of the L-shape.

[0037] As shown in FIG. 6, in the embossed portion 23, projections and recesses are formed on the rear surface of the front plate 21b. In Fig. 6(a), the surface of the front panel 21b remains flat, but the material of the front panel 21b is compressed, and in Fig. 6(b), the surface of the front panel 21b is concave. The packaging box 20 is made of a compressible material such as paper. In either case, the embossed portion 23 acts like a vertical rib, increasing the rigidity of the front plate 21b. In addition, in FIG. 6(a), the wall surface is compressed, thereby increasing the strength of the front plate 21b. Therefore, even if a load is applied to the front plate 21b, for example, when the sheet body 11 unwound from the roll product 10 rubs against the upper edge of the front plate 21b, the front plate 21b is unlikely to bend or deform. Therefore, when closing the lid 22, the blade plate 22b of the lid 22 and the front plate 21b of the main body 21 do not interfere with each other, and the blade of the blade plate 22b smoothly slides against the surface of the front plate 21b, allowing the sheet body 11 to be neatly cut. In the illustration, the embossed portion 23 is formed so that the bottom of the depression is flat.

[0038] The embossed portion 23 is disposed only on the upper portion of the front plate 21b, and is entirely hidden behind the rear surface of the blade plate 22b when the lid 22 is closed as shown in FIG. Since the lower part of the front plate 21b to which the backing plate 22c of the lid 22 is attached is not provided with the embossed portion 23, there is no possibility of poor attachment due to unevenness.

[0039] The vertical length and horizontal width of the embossed portion 23 are not particularly limited, but the vertical length is, for example, within the range of 6 mm to 25 mm, and the horizontal width is, for example, within the range of 2 mm to 30 mm. More preferably, the vertical length is within a range of 8 mm to 15 mm, and the horizontal width is within a range of 2 mm to 10 mm. Furthermore, it is preferable to set the length of the embossed portion 23 in the up-down direction to be greater than its width in the left-right direction. By setting it in this manner, it has the same effect as a so-called vertical rib, resulting in a structure that is strong against up-down (vertical) loads and further preventing deflection of the front panel 21b.

[0040] Further, the arrangement and number of the embossed portions 23 are not particularly limited, but if they are provided evenly over almost the entire area of ​​the front plate 21b in the left-right direction, a good reinforcing effect can be obtained. In the figure, there are 13 parallel embossed portions, which are divided into three groups: three on each side in the left and right directions and seven in the middle. In each group, the embossed portions 23 are parallel and equally spaced, with the spacing between adjacent groups being slightly larger than the spacing between each group.

[0041] When the deflection rate (%) of the front panel 21b having the embossed portion 23 is calculated by dividing the maximum deflection amount (mm) of the front panel 21b when the sheet body 11 is pulled out by the opening width (mm) of the main body 20 before the sheet body 11 is pulled out by 100, it is preferably 12% or less, and more preferably 4% or less.

[0042] FIG. 7 shows another example of the embossed portion 23. In Figure 7(a), a group of three embossed portions 23 on each side in the left-right direction is provided on the upper part of the front plate 21b, and a group of seven embossed portions 23 in the center in the left-right direction is provided on the lower part of the front plate 21b.

[0043] When the front panel 21b flexes and deforms, it deforms from the upper part on both sides in the left-right direction and from the lower part in the center in the left-right direction. Therefore, ignoring the issue of bonding the adhesive plate 22c, the deformation of the front panel 21b can be further suppressed by arranging the embossed portion 23 in a location that is likely to become the starting point of the deformation.

[0044] In FIG. 7(b), embossed portions 23 in the form of horizontal ribs that are long in the left-right direction are arranged in a staggered manner in the up-down direction of front plate 21b. In the case of the embossed portion 23 having a horizontal rib shape, each embossed portion 23 itself is strong against loads in the left-right direction but weak against loads in the up-down direction. However, by arranging them in a staggered pattern, it becomes possible for them to withstand loads in the up-down direction as well. EXAMPLES

[0045] The present invention will be described in more detail below with reference to examples and comparative examples. As shown in the following Table 1, examples and comparative examples were prepared by embossing the front panel of a packaging box body of "Sunfoil" (a registered trademark of Toyo Aluminium Echo Products Co., Ltd.) (household aluminum foil measuring 25 cm x 7 m). In addition, each embossed portion of the examples and comparative examples other than Comparative Example 1 and Comparative Example 4 was formed by pressing the entire inner side of a rectangle consisting of the vertical and horizontal lengths shown in Table 1 so as to be convex toward the back surface of the front panel.

[0046] [Table 1]

[0047] For the packaging bodies of the examples and comparative examples, the aluminum foil as a sheet was pulled out almost horizontally from the opening of the main body, and the degree of deformation accompanying contact with the front plate was measured, and the interference between the lid and the front plate of the main body was evaluated. The results are shown in Table 2 below. The design opening dimension was 39 mm, and the evaluation was as follows: if three or more people out of 10 judged that there was interference, it was marked with an "X", if one or two people judged that there was interference, it was marked with an "O", and if zero people judged that there was interference, it was marked with an "A". The deflection rate (%) was calculated by the amount of deflection (mm) of the front panel when the sheet body is pulled out ÷ the opening width (mm) of the main body before the sheet body is pulled out × 100. The closer the value is to zero, the smaller the amount of deflection is, which is considered to prevent interference with the front panel when the lid is closed.

[0048] [Table 2]

[0049] The embodiments and examples disclosed herein are illustrative in all respects and are not restrictive. The scope of the present invention is defined by the claims, and includes all modifications and alterations within the scope and equivalent meanings.

[0050] The fact that multiple embossed portions 23 are arranged in parallel on the left and right sides of the front panel 21b is a characteristic feature of the present invention from a technical and aesthetic standpoint, and to that extent, modifications to the embossed portions 23 in the embodiments are possible. That is, the shape of the embossed portion 23 is not limited to the embodiment, and may be circular, elliptical, polygonal, or annular in plan view. In addition, in the embodiment, the bottom of the embossed portion 23 is flat, but this is not limited, and the embossed portion 23 may have a curved shape such as a hemisphere. The embossed portion 23 may be long not only vertically or horizontally, but also obliquely. The number, intervals, and positions of the embossed portions 23 are also not limited to the embodiment. The embossed portion 23 on the front plate 21b is essential, but the back plate 21c, side plate 21d, and bottom plate 21a of the main body 21, and the blade plate 22b, side plate 22d, and top plate 22a of the lid 22 may also have embossed portions.

[0051] The configuration of the packaging box 20 excluding the embossed portion 23 and the configuration of the roll product 10 are not limited to those in the embodiment. For example, in the packaging box 20, the push-in piece 21e of the main body 21, the inner flap 21f, and the step portion 22e of the lid 22 may be omitted as appropriate, and other configurations may be added. In addition, the side panels 21d, 22d are not limited to a configuration in which the side flaps are overlapped. The roll product 10 may also be one that does not include the winding core 12 and is made up of only the sheet body 11. The winding direction of the roll product 10 that can be stored in the packaging box 20 is not limited to the so-called bottom-out direction in the embodiment, and may be an upper-out direction.
