Packing box and packing body for reel products

Abstract

The invention provides a packaging box and a packaging body of a roll product. The present invention relates to a package for a roll product, which prevents a front panel of a main body of a package box from bending and suppresses poor cutting of a sheet body when the sheet body is pulled out from the roll product. A plurality of embossing processing parts are arranged on a front panel of a main body of the packaging box. Rib-shaped recesses and projections are formed on the front panel by embossing, so that the strength of the front panel is improved. And under the condition that the material of the front panel is compressed during processing, the rigidity and the strength of the front panel are further improved. The cover is not easy to bend and deform even if a load is applied to the front panel due to friction between the sheet body and the front panel, and when the cover is required to be closed, the cover is prevented from interfering with the front panel and being unable to be smoothly closed, or a blade plate of the cover is not easy to be in sliding contact with the front panel. In addition, since only the embossing process is performed, the material cost can be reduced without consuming labor compared with a case where a reinforcing plate, a rib, etc. are added to the front panel.

Description

Technical Field

[0001] The present invention relates to a packaging box for storing a roll product formed by winding a sheet body such as aluminum foil, cling film, cooking paper, etc., and a packaging body for the roll product formed by storing the roll product in the packaging box. Background Art

[0002] Roll products made by rolling up sheets of aluminum foil, cling film, etc. are widely used. Such roll products are used for distribution, display, etc. in the form of a packaged body stored in a rectangular parallelepiped packaging box that is elongated in the left and right directions.

[0003] As described in Patent Document 1, the packaging box is composed of a main body with an opening at the top and a cover that opens and closes the opening of the main body by being rotatably connected to a back panel of the main body. The rolled product is stored in the main body of the packaging box with its axis aligned with the left-right direction of the main body.

[0004] Here, the cover of the packaging box also serves as a cutter for cutting the sheet body into a predetermined length. That is, when the sheet body is used, a predetermined length is pulled out from the roll product through the opening of the main body, and the cover is rotated so that the blade provided at the front end thereof slides in contact with the front panel of the main body, thereby the sheet body is cut by the blade while being clamped from above and below by the main body and the cover.

[0005] The cut sheet body is used for various purposes such as food packaging.

[0006] Patent Document 1: Japanese Patent Application Publication No. 2016-030634

[0007] However, although the instructions for use printed on the packaging box sometimes specify that the sheet body is to be pulled out in an upward direction, in actual use at home, the sheet body is often pulled out toward the front (horizontally).

[0008] However, if the sheet is pulled out toward the front, it is easy to interfere with the front panel of the main body of the packaging box. More specifically, the sheet rubs against the upper edge of the front panel of the main body, etc., and a load is applied to the front panel along the direction in which the sheet is pulled out, and the front panel sometimes bends and deforms so as to expand outward from its original position.

[0009] In this way, if the front panel of the main body is deformed, when the lid is to be closed, the front panel interferes with the lid and cannot be closed, or even if the lid can be closed by itself, the blade of the lid cannot slide in contact with the deformed front panel well.

[0010] Therefore, there is a problem that a cutting failure such as a breakage of the sheet body at an undesired position occurs, and the sheet body cannot be cut into a desired length. Summary of the invention

[0011] Therefore, the problem to be solved by the present invention is to prevent the front panel of the main body of the package box from bending and suppress the cutting failure of the sheet body when the sheet body is pulled out from the roll product.

[0012] In order to solve the above-mentioned problems, the packaging body of the roll product involved in the invention is composed of: a roll product formed by winding a sheet body; and a packaging box for storing the above-mentioned roll product, the above-mentioned packaging box having: a main body, which is composed of a bottom panel, a front panel and a back panel connected and arranged in an upright direction at the front edge and the rear edge of the above-mentioned bottom panel, and a right panel and a left panel connected and arranged in an upright direction at the left and right edges of the above-mentioned bottom panel, and the top surface is open, and the above-mentioned roll product is stored in a manner in which the axis of the above-mentioned roll product is consistent with the left and right directions; and a cover, which is composed of a top panel and a blade plate connected and arranged in a downward direction at the front edge of the top panel, the rear edge of the above-mentioned top panel is connected and arranged with the upper edge of the back panel of the above-mentioned packaging box main body, and the opening of the above-mentioned packaging box main body can be opened and closed by rotating the whole body, and the above-mentioned sheet body pulled out from the above-mentioned roll product through the opening of the above-mentioned packaging box main body to the front side can be cut by making the above-mentioned blade plate slide and contact with the front panel of the above-mentioned packaging box main body when the opening is closed, and a plurality of embossed processing parts arranged in the left and right directions are provided on the front panel of the main body of the above-mentioned packaging box.

[0013] If so constituted, then by embossing and forming rib-shaped concavoconvex on the front panel, its strength is improved. In addition, when the material of the packaging box is made of paper or the like, the material is compressed during processing, thereby further improving the rigidity and strength of the front panel.

[0014] Therefore, even if the sheet body rubs against the front panel and a load is applied to the front panel, the front panel is not easily bent or deformed. When the cover is to be closed, the cover is prevented from interfering with the front panel and failing to close smoothly, or from making it difficult for the blade of the cover to slide in contact with the front panel.

[0015] Since the embossing process is performed only on the front panel, compared with the case where a reinforcing plate, ribs, etc. are added to the front panel, labor is not required and material costs can be suppressed.

[0016] In the package of the rolled product according to the present invention, it is preferable that the plurality of embossed portions each be configured to extend in the up-down direction of the front panel.

[0017] With this structure, the same function as a so-called longitudinal rib is achieved, and thus the structure has a strong ability to resist loads in the up-and-down direction (longitudinal direction), and can further prevent bending of the front panel.

[0018] In the package of the rolled product according to the present invention, it is preferred that the plurality of embossed portions each be convex toward the back surface of the front plate.

[0019] Since a load is applied from the sheet body pulled toward the front direction, when the front panel of the main body attempts to bend in the direction of expanding outward, the front panel is easily bent starting from the embossed portion if the embossed portion protrudes toward the surface of the front panel (is recessed toward the back).

[0020] By making the embossed portion protrude toward the back surface of the front panel, the front panel is less likely to bend due to outward expansion, and deformation of the front panel can be further prevented.

[0021] In the packaging body of the roll product involved in the invention, the above-mentioned multiple embossed parts preferably adopt the following structure: the length of each in the up and down direction is in the range of 6mm to 25mm, the width in the left and right direction is in the range of 2mm to 30mm, and the above-mentioned multiple embossed parts are evenly spaced and arranged in the entire area of ​​the left and right direction of the above-mentioned front panel.

[0022] This configuration can provide an optimal structure for preventing the front panel of the main body from bending.

[0023] If the length of the embossed portion in the up-down direction is less than 6 mm and the width in the left-right direction is less than 2 mm, the dimensions are too small, and therefore a sufficient effect of preventing bending may not be obtained in each embossed portion.

[0024] If the length of the embossed portion in the vertical direction exceeds 25 mm and the width in the horizontal direction exceeds 30 mm, the size is too large, so it is difficult to set a plurality of embossed portions, and the overall anti-bending effect of the plurality of embossed portions may be insufficient. In addition, the adhesion of the cover to the front panel when not in use may be hindered.

[0025] In the package of the rolled product according to the present invention, the plurality of embossed portions are preferably configured to be provided only at a portion of the front plate that overlaps with the blade when the opening is closed.

[0026] In the packaging body of a general roll product, in order to prevent the cover from being opened when not in use, a sticker (opening tape) is connected to the lower edge of the blade plate. It is glued to the lower part of the front panel. When in use, it can be opened by cutting the sticker off the blade plate.

[0027] Here, if an embossed portion is provided at the portion of the front panel where the cover sheet is attached, the embossed portion may easily cause poor attachment due to the unevenness, and the cover may be accidentally opened during transportation of the package.

[0028] By arranging the embossed portion only on the upper part of the front panel overlapping with the blade plate, there is no unevenness on the lower part of the front panel where the pasting plate is pasted, thereby preventing poor pasting. In addition, when not in use, the unevenness of the embossed portion is hidden in the blade plate and cannot be visually confirmed from the outside, so the appearance is good.

[0029] In the package of the rolled product according to the invention, the rolled product is preferably housed in the package body in a winding direction in which the outer end of the roll is pulled out from the lower side toward the upper side of the package body.

[0030] As the rolled product is stored in the main body, there is a so-called downward winding direction in which the outer end of the sheet body is pulled from the lower side of the main body of the packaging box toward the upper side, and a so-called upward winding direction in which the outer end of the sheet body is pulled from the upper side. In the downward winding direction, the sheet body is more likely to rub against the front panel when pulled out, so the front panel is more likely to bend and deform.

[0031] Therefore, compared with the case of upward exit, in the case of downward exit, the effect of preventing bending deformation is more significant by providing an embossed portion on the front body.

[0032] When the rolled product is stored in the downward-outward state, the end is greatly bent (folded back) when the sheet is cut, thereby suppressing rewinding. When the sheet is pulled out next time, it is easy to pinch the end, etc., and the operation can be performed smoothly.

[0033] In the packaging body of the roll product involved in the invention, the front panel of the above-mentioned main body preferably adopts the following structure: the curvature calculated by the bending amount (mm) of the front panel when pulling out the above-mentioned sheet body ÷ the opening width (mm) of the main body before pulling out the above-mentioned sheet body × 100 is less than 12%.

[0034] The smaller the curvature value, the smaller the deformation of the front panel. Therefore, the lower limit is preferably 0% or less. By setting the curvature to a constant value or less, interference with the front panel when the lid is closed can be sufficiently prevented.

[0035] In addition, in order to solve the above-mentioned problems, the packaging box of the roll product involved in the invention is constructed as follows: a main body, which is composed of a bottom panel, a front panel and a back panel connected in an upright direction at the front edge and the rear edge of the above-mentioned bottom panel, and a right panel and a left panel connected in an upright direction at the left and right edges of the above-mentioned bottom panel, and the top surface is open, and the above-mentioned roll product is stored in a manner such that the axis of the above-mentioned roll product is consistent with the left and right directions; and a cover, which is composed of a top panel and a blade plate connected in a downward direction at the front edge of the top panel, the rear edge of the above-mentioned top panel is connected to the upper edge of the back panel of the above-mentioned packaging box main body, and the opening of the above-mentioned packaging box main body can be opened and closed by rotating the whole body, and the above-mentioned sheet body pulled out from the above-mentioned roll product through the opening of the above-mentioned packaging box main body to the front side can be cut by making the above-mentioned blade plate slide in contact with the front panel of the above-mentioned packaging box main body when the opening is closed, and a plurality of embossed processing parts arranged in the left and right directions are provided on the front panel of the above-mentioned main body.

[0036] Since the package body and the package box of the rolled product according to the present invention are configured as described above, when the sheet body is pulled out from the rolled product, the front panel of the main body of the package box is prevented from bending, thereby suppressing cutting defects.

DETAILED DESCRIPTION

[0046] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0047] Figures 1 to 3 The packaging body 1 of the rolled product of the embodiment shown is composed of a rolled product 10 and a packaging box 20 of an embodiment for storing the rolled product. The rolled product 10 is composed of a sheet body 11, and in the packaging box 20 with a cutting function for cutting the sheet body 11 from the rolled product 10, the cutting can be performed smoothly.

[0048] like Figure 3 As shown, the roll product 10 has an elongated cylindrical shape and is formed by winding a sheet body 11 around a winding core 12 .

[0049] The type of the sheet body 11 is not particularly limited, and examples thereof include aluminum foil, cling film, and cooking paper. The material of the sheet body 11 is also not particularly limited, and examples thereof include metal, synthetic resin, and paper.

[0050] The material of the core 12 is not particularly limited, and paper is exemplified. The core 12 may be omitted, and the roll product 10 may be formed of only the sheet body 11 .

[0051] like Figures 1 to 3 As shown, the package box 20 of the rolled product of the embodiment is in the shape of a rectangular parallelepiped elongated in the left-right direction, and is composed of a main body 21 and a cover 22 .

[0052] The material of the package box 20 is not particularly limited, and paper is exemplified.

[0053] The main body 21 is composed of a bottom panel 21a, a front panel 21b and a back panel 21c connected in an upright manner at the front and rear edges of the bottom panel 21a, and a side panel 21d connected in an upright manner at the left and right edges of the bottom panel 21a, and the top surface is open.

[0054] The rolled product 10 is housed in the main body 21 so that the axis thereof coincides with the left-right direction of the main body 21 .

[0055] The rolled product 10 can rotate inside the main body 21 around its axis, and the sheet body 11 is pulled out through the opening of the main body 21 in accordance with the rotation.

[0056] Here, the rolled product 10 is stored in a so-called downward winding direction, that is, a winding direction in which the end portion is pulled out from the lower side toward the upper side.

[0057] The left and right side panels 21 d are provided with a press-in piece 21 e divided by an easy-to-break line formed by a perforation or the like. When in use, the easy-to-break line is broken and the press-in piece 21 e is pressed into the core 12 of the rolled product 10 .

[0058] The pressing piece 21 e prevents the rotating rolled product 10 from flying out of the opening of the main body 21 when the sheet body 11 is pulled out.

[0059] The inner wing pieces 21f are connected to the upper edges of the left and right side panels 21d. The inner wing pieces 21f and the side panels 21d are separated by a U-shaped slit to form locking pieces 21g. When the inner wing pieces 21f fall inward, the locking pieces 21g are cut and protrude outward.

[0060] The cover 22 is composed of a top panel 22a, a blade plate 22b connected to the front edge of the top panel 22a in a hanging manner, a contact plate 22c connected to the lower edge of the blade plate 22b, and side panels 22d connected to the left and right sides of the top panel 22a.

[0061] The rear edge of the top plate 22a of the cover 22 is connected to the upper edge of the back plate 21c and can rotate around this point.

[0062] A plurality of blades arranged in the left-right direction are formed at the lower edge of the blade plate 22b. The sheet body 11 is cut by the blades.

[0063] The boundary between the attached plate 22c and the blade plate 22b is formed with an easy break line formed by a perforation or the like. In addition, the attached plate 22c is attached to the lower surface of the front plate 21b of the main body 21. Thus, the cover 22 is fixed in a state of closing the opening of the main body 21.

[0064] When the package 1 is used, the break line is broken and the adhesive plate 22c serving as the opening tape is cut off from the blade 22b. Thus, the cover 22 is released from being fixed and the cover 22 is rotatable between a closed position for sealing the opening of the main body 21 and an open position for opening the opening of the main body 21.

[0065] First, with the cover 22 in the open position, the rolled product 10 is rotated to pull the sheet body 11 out of the opening of the main body 21 by a desired length.

[0066] Next, when the cover 22 is rotated to the closed position and the blade 22b is lowered while sliding against the surface of the front plate 21b of the main body 21, the sheet 11 is cut by the blade of the blade 22b while being clamped from above and below.

[0067] Step portions 22e are formed on the back surfaces of the side panels 22d of the cover 22, respectively.

[0068] When the cover 22 is rotated to the closed position, the locking piece 21g cut out from the inner wing piece 21f of the main body 21 is fitted into the step portion 22e.

[0069] Thus, the opening of the main body 21 is kept closed by the cover 22 , and the cover 22 is prevented from being accidentally opened.

[0070] Furthermore, the step portion 22e is shallow in depth and the locking piece 21g is only lightly embedded therein, so when an attempt is made to rotate the cover 22 to the open position with a slight force, the locking piece 21g is pulled out of the step portion 22e to release the lock.

[0071] Although not particularly limited, such a packaging box 20 is assembled Figure 4 The blank 20' is made.

[0072] The blank 20' is formed by punching a sheet such as cardboard and has 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 arranged in order from top to bottom via ruled lines or easy-to-break lines.

[0073] By bending each grid line or fragile line to form a square tube, Figure 5 As shown, the main body 21 is formed by the front plate 21b, the bottom plate 21a, and the back plate 21c, and the main body of the cover 22 is formed by the top plate 22a, the blade plate 22b, and the attachment plate 22c.

[0074] In addition, if Figure 4 As shown, the blank 20' has side flaps 21d at the left and right edges of the front panel 21b, the bottom panel 21a, and the back panel 21c via ruled lines.

[0075] By bending the grid line and overlapping and fitting the side wings 21d, Figure 5 As shown, the left and right side panels 21d of the main body 21 are formed. The inner side panels 21f are provided on the outer sides of the side panels 21d of the bottom panel 21a in a continuous manner via a grid line or the like.

[0076] Furthermore, the blank 20' has side wings 22d at the left and right edges of the top plate 22a and the blade plate 22b via ruled lines.

[0077] By bending the grid line, the side wings 22d are overlapped and attached, so that Figure 5 As shown, left and right side panels 22d of the cover 22 are formed.

[0078] At this time, since the side wing pieces 22d of the top plate 22a and the blade plate 22b have different sizes, the side wing pieces 22d do not completely overlap each other, and therefore a step portion 22e is formed on the back surface of the side plate 22d.

[0079] like Figure 1 and Figure 3 As shown, a plurality of embossed portions 23 are formed by embossing the front plate 21 b of the main body 21 .

[0080] The plurality of embossed portions 23 each have an elongated oval shape and are arranged such that the major axis direction coincides with the vertical direction of the front plate 21 b of the main body 21 , that is, extends in the vertical direction.

[0081] In addition, the embossed parts 23 are arranged in the left-right direction of the front plate 21b.

[0082] In addition, the embossed portion 23 of the embodiment of the present invention is formed with Figure 1 The embossing shown is one in which the inside of the solid line portion of the letter "ロ" is completely pressed and recessed, but it may be one in which only the grid lines of the solid line portion of the letter "ロ" are pressed.

[0083] like Figure 6 As shown, in the embossed portion 23, projections and depressions are formed so as to protrude on the back surface of the front plate 21b.

[0084] exist Figure 6 In (a), the surface of the front panel 21b remains flat, but the material of the front panel 21b is compressed. Figure 6 In (b), the surface of the front panel 21b is concave. The package box 20 is formed of a compressible material such as paper.

[0085] In either case, since the embossed portion 23 acts as a longitudinal rib, the rigidity of the front panel 21b is increased. Figure 6 In (a), on this basis, the wall surface is compressed, so the strength of the front panel 21b is increased.

[0086] Therefore, even when a load is applied to the front panel 21 b due to friction between the sheet body 11 pulled out from the roll product 10 and the upper edge of the front panel 21 b, the front panel 21 b is unlikely to bend and deform.

[0087] Therefore, when the cover 22 is closed, the blade 22b of the cover 22 does not interfere with the front plate 21b of the body 21, and the blade 22b can smoothly slide in contact with the surface of the front plate 21b, thereby neatly cutting the sheet 11.

[0088] In the drawings, the bottom of the depression of the embossed portion 23 is formed flat.

[0089] The embossed portion 23 is only disposed on the upper portion of the front panel 21b. Figure 2 As shown, when the cover 22 is closed, all of them are hidden behind the back of the blade plate 22b.

[0090] Since the embossed portion 23 is not provided on the lower portion of the front plate 21b to which the attaching plate 22c of the cover 22 is attached, defective attachment due to the unevenness thereof does not occur.

[0091] The vertical length and horizontal width of the embossed portion 23 are not particularly limited, but the vertical length is 6 mm to 25 mm, and the horizontal width is 2 mm to 30 mm.

[0092] More preferably, the length in the up-down direction is in the range of 8 mm to 15 mm, and the width in the left-right direction is in the range of 2 mm to 10 mm.

[0093] In addition, in the embossed portion 23, the length in the up-down direction is preferably set to be greater than the width in the left-right direction. By adopting such a setting, the same role as the so-called longitudinal rib is achieved, thereby becoming a structure with strong load capacity to resist the up-down direction (longitudinal direction), which can further prevent bending of the front panel 21b.

[0094] The arrangement and number of the embossed portions 23 are not particularly limited, and a good reinforcement effect can be obtained if the embossed portions 23 are provided over substantially the entire region in the left-right direction of the front plate 21 b .

[0095] In the figure, there are 13 arranged, 3 on each side in the left and right direction, 7 in the center, and a total of 3 groups. In each group, the embossed parts 23 are arranged at equal intervals, and the intervals between adjacent groups are slightly larger than the intervals in each group.

[0096] When the curvature (%) of the front panel 21b provided with the embossed portion 23 is calculated by the maximum curvature amount (mm) of the front panel 21b when the sheet body 11 is pulled out ÷ the opening width (mm) of the main body 20 before the sheet body 11 is pulled out × 100, it is preferably less than 12%, and more preferably less than 4%.

[0097] Figure 7 Another example of the embossed portion 23 is shown.

[0098] exist Figure 7 In (a), a group consisting of three embossed portions 23 on both sides in the left-right direction is arranged at the upper part of the front panel 21b, and a group consisting of seven embossed portions 23 in the center in the left-right direction is arranged at the lower part of the front panel 21b.

[0099] When the front panel 21b is bent and deformed, the deformation starts 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, if the problem of pasting the pasting plate 22c is ignored, the deformation of the front panel 21b can be further suppressed by arranging the embossed portion 23 at a position that is likely to become the starting point of the deformation.

[0100] exist Figure 7 In (b), the embossed portion 23 in the form of a transverse rib that is long in the left-right direction is arranged in a zigzag shape to form a height difference in the up-down direction of the front panel 21b.

[0101] In the case of the transverse rib-shaped embossed portions 23, although each embossed portion 23 itself has a strong ability to resist loads in the left-right direction, it is weak in the ability to resist loads in the up-down direction. By arranging them in a zigzag pattern, they can also withstand loads in the up-down direction.

[0102] Hereinafter, examples and comparative examples of the present invention will be listed to further clarify the contents of the present invention.

[0103] As shown in Table 1 below, Examples and Comparative Examples were prepared in which the front panel of the package box body of "Sunfoil" (a registered trademark of Toyo Aluminum Co., Ltd.) (a 25 cm x 7 m household aluminum foil) manufactured by Toyo Aluminum Co., Ltd. was embossed.

[0104] In addition, each embossed portion of the Examples and Comparative Examples other than Comparative Examples 1 and 4 was formed by pressing the entire inside of a rectangle having the vertical and horizontal lengths shown in Table 1 so as to protrude toward the back surface of the front plate.

[0105] 【Table 1

[0106]

[0107] Regarding the packaging bodies of Examples and Comparative Examples, the aluminum foil as a sheet was pulled out substantially horizontally from the opening of the body, and the degree of deformation due to contact with the front plate was measured to evaluate the interference between the cover and the front body of the body.

[0108] The results are shown in Table 2 below.

[0109] In addition, the design opening size is set to 39 mm. Regarding the evaluation, the case where the number of people judged to be interference is 3 or more among 10 people is ×, the case where the same number of people is 1 or 2 is 0, and the case where the same number of people is 0 is ◎.

[0110] The curvature (%) is defined as the curvature of the front panel when the sheet is pulled out (mm) ÷ the opening width of the main body before the sheet is pulled out (mm) × 100. The closer the value is to zero, the smaller the curvature is, and it is considered that interference with the front panel when the cover is closed can be prevented.

[0111] 【Table 2

[0112]

[0113] The embodiments and examples disclosed this time are illustrative in all aspects and are not restrictive.

[0114] The scope of the present invention is indicated by the scope of the claims and is intended to include all modifications and changes within the scope and equivalents thereto.

[0115] The fact that a plurality of embossed portions 23 are arranged side by side on the front plate 21 b is a characteristic point of the present invention from the technical and aesthetic viewpoints, and the embossed portions 23 of the embodiment can be modified within this range.

[0116] That is, the shape of the embossed portion 23 is not limited to the embodiment, and can be circular, elliptical, polygonal, or ring-shaped when viewed from above. In addition, in the embodiment, the bottom of the embossed portion 23 is flat, but it is not limited to this, and can also be a shape that draws a curve as a whole, such as a hemispherical shape. The embossed portion 23 is not only long in the vertical direction or horizontal direction, but can also be a shape that is long in the inclined direction.
