[0010] The present invention will now be described based on preferred embodiments with reference to the drawings. 1 to 5 show one embodiment of the packaging box for hair dye of the present invention (hereinafter, simply referred to as packaging box). The packaging box 10 of this embodiment is adapted to house a storage container for a hair dye inside, and when the storage container for a hair dye is housed inside, the packaging box 10 and the storage container for a hair dye together constitute a packaged product 1 for a hair dye. The packaging box 10 includes both a box with a storage container for a hair dye housed inside and a box without a storage container for a hair dye housed inside. In this embodiment, two storage containers 4a, 4b corresponding to two-part hair dyes that are mixed when used are stored inside the packaging box 10. The packaged product 1 includes the storage containers 4a, 4b and the packaging box 10 for the hair dye that stores the storage containers 4a, 4b.

[0011] The storage container for the hair dye may be a pouch container, and the number of storage containers stored in the packaging box may be one or more. In this embodiment, the storage container 4a is a tube container in which a first agent constituting the hair cosmetic is stored, and the other storage container 4b is a tube container in which a second agent constituting the hair cosmetic is stored. In this embodiment, two storage containers 4a and 4b are stored in the storage space V of the packaging box 10, but other storage containers may also be stored. Note that the storage containers 4a and 4b in this embodiment each include a tube body in which the above-mentioned agent is stored. Each tube body includes a body portion made of a cylindrical tube body, an end seal portion formed between the inner surfaces at one end of the tube body in the longitudinal direction by a known method such as heat fusion or ultrasonic waves, and a cap portion detachably attached to a neck portion connected to the other end of the tube body in the longitudinal direction. The body of the tube container may be made of synthetic resin or aluminum, or may be a laminate of a synthetic resin layer and a metal layer such as aluminum.

[0012] The packaging box 10 has a hollow three-dimensional shape. The packaging box 10 of the present embodiment has a hollow hexahedral shape. The three-dimensional shape of the packaging box 10 is not particularly limited, and may be a columnar shape such as a cylinder, a triangular prism, or a pentagonal prism, a pyramidal shape such as a cone, a triangular pyramid, or a quadrangular pyramid, or a polyhedral shape such as an octahedron or a dodecahedron. The packaging box 10 of this embodiment is configured to include a cylindrical peripheral wall portion 2, a top surface portion 12, and a bottom surface portion 13 (see FIG. 1). The peripheral wall portion 2 stands upright from the periphery of the bottom surface portion 13. The bottom surface portion 13 closes one opening of the peripheral wall portion 2.

[0013] The packaging box 10 is for storing the hair dye containers 4a and 4b, and has an internal storage space V for storing the containers 4a and 4b (see FIG. 1). The storage space V is a space defined by the peripheral wall 2, the top surface 12, and the bottom surface 13, mainly consisting of the internal space of the cylindrical structure of the peripheral wall 2. The peripheral wall 2 of this embodiment has a quadrangular prism shape in which the horizontal cross section of the peripheral wall 2 is rectangular. More specifically, the peripheral wall 2 is formed by a front surface 14, a back surface 15 facing the front surface 14 in the depth direction X, and a pair of side surfaces 16 and 17 disposed between the front surface 14 and the back surface 15 and facing each other in the width direction Y. The front surface 14 and the back surface 15 face each other, and the pair of side surfaces 16 and 17 face each other between the front surface 14 and the back surface 15. This makes the peripheral wall 2 cylindrical. The front portion 14, the rear portion 15, and the side portions 16, 17 have the same height, but the front portion 14 and the rear portion 15 have a longer circumferential length than the side portions 16, 17.

[0014] The packaging box 10 of this embodiment can stand on its own with its height direction Z aligned along the vertical direction, as shown in Fig. 1. In this state, the height direction Z of the packaging box 10 coincides with the vertical direction. That is, the bottom surface portion 13 of the packaging box 10 faces downward, and the top surface portion 12 facing the bottom surface portion 13 faces upward. The packaging box 10 of this embodiment has a width direction Y along the width of the front portion 14 and the back portion 15, a depth direction X perpendicular to the width direction Y, and a height direction Z perpendicular to the width direction Y and the depth direction X. The depth direction X is a direction along the side portions 16, 17.

[0015] The top surface portion 12 includes top surface side flaps 18, 19 connected to the upper ends of the pair of left and right side portions 16, 17 via fold lines 3a, 3b, respectively, a rear top surface flap 20 connected to the upper end of the back surface portion 15 via fold line 3c, and a front top surface flap 21 connected to the upper end of the front surface portion 14 via fold line 3d (see FIG. 1). With this configuration, the top surface portion 12 closes the opening of the peripheral wall portion 2 on the top surface portion 12 side by the pair of top surface side flaps 18, 19, the rear top surface flap 20, and the front top surface flap 21. In the packaging box 10, the "inside" means the inside side of the packaging box 10 (the storage space V side), and the "outside" means the outside side of the packaging box 10.

[0016] A rectangular grip portion 31 is formed on the side surface 16. The grip portion 31 is a portion that is held by the user's fingers or the like when tearing the packaging box 10 along the cutting guide line FL described below. This makes it easier to tear the packaging box 10 along the cutting guide line FL, and makes it easier to produce a mixing tray 30 that can be used to mix hair dyes. From the viewpoint of making it easier to tear the packaging box 10 along the cutting guide line FL, it is preferable that the packaging box 10 is formed with the grip portion 31, but the grip portion 31 is not necessarily required.

[0017] The packaging box 10 has an opening 26 and a cutting guide line FL surrounding the opening 26 formed across the side portion 16, the front portion 14, and the side portion 17. The cutting guide line FL extends in the height direction Z and the depth direction X in the side portions 16 and 17, and extends in the width direction Y in the front portion 14 so as to surround the opening 26 (see FIG. 1). The tray portion 22 in this embodiment is an area surrounded by the cutting guide line FL, and forms the outer surface of the packaging box 10 before separation. From the viewpoint of resource saving, the area of ​​the outer surface of the packaging box 10 consisting of the tray portion 22 is preferably 10% or more, preferably 20% or more, and preferably 90% or less, preferably 70% or less of the total area of ​​the outer surface of the packaging box 10. The tear guide lines are preferably formed by perforations.

[0018] The opening 26 is formed across the side portion 16, the front portion 14, and the side portion 17. The opening 26 is for allowing the contents stored in the storage space V of the packaging box 10 to be seen from the outside. The packaging box 10 is provided with a transparent sheet 27 to cover the opening 26. The transparent sheet 27 is formed from a plastic sheet material. Hereinafter, the portion where the opening 26 and the transparent sheet 27 overlap when the packaging box 10 is viewed from the outside is also referred to as a transparent portion 28. The transparent sheet 27 is bonded at its periphery to the inner sides of the side portion 16, the front portion 14, and the side portion 17. Such bonding can be achieved by using a known bonding means such as an adhesive. Any shape can be selected as the shape of the opening 26. In the packaging box 10 of the present embodiment, the opening 26 is formed across the side surface portion 16, the front surface portion 14, and the side surface portion 17, but it is sufficient that the opening 26 is formed at least in the front surface portion 14.

[0019] The transparent sheet 27 is preferably a single-layer or multi-layer resin film made of any one of polyesters such as polyethylene terephthalate (PET), polyethylene naphthalate (PEN), and polybutylene terephthalate (PBT), polyolefins such as polyethylene (PE) and polypropylene (PP), polyamide (PA), polyacrylonitrile (PAN), polyimide (PI), polyvinyl chloride (PVC), and polyvinylidene chloride (PVDC). The transparent sheet 27 may be any shape as long as it can cover the entire opening 26.

[0020] The packaging box 10 has a tray portion 22 at one part thereof which forms a mixing tray 30 which can be used for mixing hair dyes. The mixing tray 30 is formed by separating the tray portion 22 from the packaging box 10. More specifically, the packaging box 10 of this embodiment is formed by pulling the tab portion 31 of the packaging box 10 before use toward the outside of the packaging box 10, thereby breaking the packaging box 10 along the tear guide line FL and separating the packaging box 10 from the tray portion 22. This operation forms an opening along the periphery of the tray portion 22 in the packaging box 10, and also forms the mixing tray 30 which can be used for mixing hair dyes (see FIG. 3).

[0021] The packaging box 10 of this embodiment functions as a packaging container for the storage containers 4a and 4b, and by separating a portion of the packaging box 10, a mixing tray 3 that can be used to mix hair dyes can be produced. Therefore, according to the packaging box 10 of this embodiment, when distributing the packaging box 10 of the present invention to the market, there is no need to provide a separate outer box or mixing tray, so the overall amount of synthetic resin used can be reduced, which contributes to reducing the environmental impact. Furthermore, since there is no need to provide a separate outer box or mixing tray, it is possible to reduce the size of the packaged product 1 compared to conventional products, which improves the transportation efficiency of the packaged product 1 during the distribution process and also reduces the volume of waste. In addition, since the packaging box 10 includes a plastic transparent portion 28, when the packaging box 10 is viewed from the outside, the inside of the packaging box 10 can be seen through the transparent portion 28. That is, the storage containers 4a, 4b and other contents such as one or more bag-shaped containers stored in the storage space V can be directly seen through the transparent portion 28. In addition, the packaging box 10 is designed so that, if desired, package inserts, decorations, etc. displayed on the surface of the rear portion 15 facing the storage space V can be seen through the packaging box 10, thereby enhancing the display effect and decorative effect.

[0022] In terms of enhancing the visibility of the hair dye container and / or the display effect and decorative effect, the ratio (S2 / S1) of the area S2 of the transparent portion 28 in the front portion 14 to the area S1 of the front portion 14 is preferably 0.35 or more, more preferably 0.50 or more. In terms of the ease of opening (ease of breaking the cutting guide line FL) and the durability of the packaging box 10, the ratio (S2 / S1) of the area S2 of the transparent portion 28 in the front portion 14 to the area S1 of the front portion 14 is preferably 0.90 or less, more preferably 0.75 or less. Taking the above into consideration, the ratio (S2 / S1) of the area S2 of the transparent portion 28 in the front portion 14 to the area S1 of the front portion 14 is preferably 0.35 or more and 0.90 or less, more preferably 0.50 or more and 0.75 or less. The area S1 of the front portion 14 is preferably 5000 mm 2 More than 20000mm 2 Less than or equal to 7500mm, more preferably 2 More than 15000mm 2 The following is the result. The area S2 of the transparent portion 28 in the front portion 14 is preferably 1750 mm 2 More than 18000mm 2 Less than or equal to 3750mm, more preferably 2 More than 11250mm 2 The following is the result. The area S1 of the front portion 14 can be calculated by multiplying the length L1 of the front portion 14 in the height direction Z by the length L2 of the front portion 14 in the width direction Y, and the area S2 of the transparent portion 28 in the front portion 14 can be calculated by multiplying the length L3 of the transparent portion 28 in the height direction Z by the length L4 of the transparent portion 28 in the width direction Y.

[0023] The mixing tray 30 of this embodiment has a flat wall portion 32 that forms the bottom surface, and a pair of opposing upright wall portions 33 located around the flat wall portion 32 (see FIG. 3). The flat wall portion 32 forms the bottom wall of the mixing tray 30 when the mixing tray 30 is used as a tray for mixing the agents contained in the storage containers 4a and 4b. The mixing tray 30 is used with the flat wall portion 32 facing vertically downward. The upright wall portion 33 is formed by a pair of side upright walls 23 and 24 facing each other in the depth direction X1. The side upright wall portion 24 is provided with a knob portion 31. In the mixing tray 30 of this embodiment, the side upright walls 23, 24 rise from the end of the flat wall 32. The upright wall 33 preferably rises perpendicular to the flat wall 32, but is not limited to being perpendicular. The term "perpendicular" as used herein does not necessarily mean that the angle between the flat wall 32 and the upright wall 33 on the inside of the packaging box 10 (this angle is also called the rise angle) is 90°, but also means that the angle is approximately perpendicular, for example, the rise angle is 70° or more and 110° or less. In the mixing tray 30, the rise angle is usually less than 180°, preferably less than 170°, and more preferably less than 150°.

[0024] Before being separated from the packaging box 10 as the mixing tray 30, the portion that becomes the flat wall portion 32 of the mixing tray 30 forms part of one face of the cubic-shaped packaging box 10, i.e., part of the front portion 14, and the portions that become the side upright walls 23, 24 of the mixing tray 30 form part of the other face perpendicular to the one face of the cubic-shaped packaging box 10, i.e., part of the side portions 16, 17. In this way, if the flat wall 32 and the side standing walls 23, 24 of the mixing tray 30 form surfaces perpendicular to each other in the packaging box 10 before being separated into the mixing tray 30, the flat wall 32 and the side standing walls 23, 24 are formed to have an angle therebetween, so that when separated into the mixing tray 30, the side standing walls 23, 24 tend to stand up relative to the flat wall 32 and tend to function as a three-dimensional barrier to prevent leakage of the hair dye. Also, the operation of folding the standing wall 33 to form an angle with the flat wall 32 is unnecessary or becomes extremely easy, making the preparation operation of the mixing tray 30 simple. The perpendicular angle between the surfaces of the packaging container is not limited to 90°, and also includes a case where the angle is approximately perpendicular, for example, an angle on the inside side of the packaging box 10 (also simply referred to as the angle formed) of 70° to 110°. In the state of the packaging container 10, the angle formed by the front portion 14, the whole or a part of which becomes the flat wall portion 32, and each of the side portions 16, 17, the parts of which become the flat wall portion 32, is preferably 70° to 110°, more preferably 80° to 100°, and further preferably 85° to 95°.

[0025] The mixing tray 30 of this embodiment includes a transparent sheet 27 on the flat wall portion 32, so that when the mixing tray 30 is used as a tray for mixing hair dye, it is possible to prevent the hair dye from seeping out of the mixing tray 30, and it is also easy to wipe off the hair dye and reuse it as a tray for mixing hair dye. In the mixing tray 30 of this embodiment, it is preferable that the transparent sheet 27 is disposed on the rising portions 29 of the side standing walls 23, 24, which are the boundaries between the flat wall portion 32 and each of the side standing walls 23, 24. In other words, it is preferable that the transparent sheet 27 is disposed across the flat wall portion 32 and the side standing walls 23, 24. In this way, it is possible to more reliably prevent the hair dye from seeping out when the mixing tray 30 is used. In order to further suppress the bleeding of the hair dye, the length of the transparent sheet 27 arranged in the rising portion 29 in the direction along the upright wall portion 33, i.e., the length L10 in the width direction Y1, is preferably 50% or more, and more preferably 70% or more, of the length L5 in the same direction of the flat wall portion 32.

[0026] 3 shows the mixing tray 30, which can be used for mixing hair dyes by cutting it out from the packaging box 10, with the flat wall portion 32 of the mixing tray 30 facing vertically downward. In this state, the thickness direction Z1 of the mixing tray 30 coincides with the vertical direction. In this state, the mixing tray 30 has a width direction Y1 along the width of the pair of side upright walls 23, 24 and a depth direction X1 perpendicular to the width direction Y1.

[0027] When the mixing tray 30 has a non-transparent portion 5 on the flat wall portion 32 that is not covered with the transparent sheet 27, the basis weight of the non-transparent portion 5 is set to 170 g / m2 in order to prevent the hair dye from seeping out. 2 More than 270g / m 2 More preferably, the basis weight of the non-transparent portion 5 is 1000 g / m2 or more from the viewpoint of ease of assembly and strength of the packaging box 10. 2 Less than 500 g / m 2 Taking the above into account, the basis weight of the non-transparent portion 5 is preferably 170 g / m 2 More than 1000g / m 2 Less than 270 g / m 2 More than 500g / m 2 The following is more preferred: In addition, from the viewpoint of suppressing bleeding of the hair dye, the ratio (S5 / S3) of the area S5 of the transparent sheet 27 in the flat wall portion 32 to the area S3 of the flat wall portion 32 is preferably 0.50 or more, more preferably 0.60 or more. From the viewpoint of ensuring the adhesive strength between the transparent sheet 27 and the flat wall portion 32, the ratio (S5 / S3) of the area S5 of the transparent sheet 27 in the flat wall portion 32 to the area S3 of the flat wall portion 32 is preferably 0.95 or less, more preferably 0.90 or less. Taking the above into consideration, the ratio (S5 / S3) of the area S5 of the transparent sheet 27 in the flat wall portion 32 to the area S3 of the flat wall portion 32 is preferably 0.50 or more and 0.95 or less, more preferably 0.60 or more and 0.90 or less. The area S3 of the flat wall portion 32 can be calculated by multiplying the length L5 of the flat wall portion 32 in the width direction Y1 by the length L6 of the flat wall portion 32 in the depth direction X1. The area S5 of the transparent sheet 27 on the flat wall portion 32 can be calculated by multiplying the length L10 of the transparent sheet 27 in the width direction Y1 by the length L11 of the transparent sheet 27 on the flat wall portion 32 in the depth direction X1.

[0028] The operability of the mixing tray 30 of the packaging box 10 can be evaluated using the value (S3 / L7) obtained by dividing the area S3 of the flat wall portion 32 by the height L7 of the upright wall portion 33 as a measure. In the present invention, from the viewpoint of preventing a spatula or a user's fingers from coming into contact with the mixing tray 30 during mixing and facilitating mixing of a plurality of agents, this value (hereinafter also referred to as the "flatness") is preferably 7 mm or more, more preferably 35 mm or more, even more preferably 100 mm or more, preferably 1500 mm or less, more preferably 1000 mm or less, and even more preferably 500 mm or less. Taking the above into consideration, the flatness is preferably 7 mm or more and 1500 mm or less, more preferably 35 mm or more and 1000 mm or less, and even more preferably 100 mm or more and 500 mm or less. The larger the flatness value, the flatter the mixing tray 30 is. In this specification, flat means that the area S3 of the flat wall portion 32 of the mixing tray 30 is relatively large compared to the height L7 of the upright wall portion 33, and that the depth of the space used to store and mix the hair dye is not very deep, making mixing, etc. easy. The height L7 of the upright wall portion 33 referred to here is the distance between the upper edge of the side upright wall portion 23 and the inner surface of the flat wall portion 32.

[0029] In the mixing tray 30, the height L7 in the thickness direction Z1 of the standing wall portion 33 is preferably 10 mm or more, more preferably 30 mm or more, from the viewpoint of suppressing unintended scattering when the hair dyes are mixed. Also, from the viewpoint of facilitating mixing of a plurality of agents, the height L7 in the thickness direction Z1 of the standing wall portion 33 is preferably 70 mm or less, more preferably 60 mm or less. Taking the above into consideration, the height L7 in the thickness direction Z1 of the standing wall portion 33 of the mixing tray 30 is preferably 10 mm or more and 70 mm or less, more preferably 30 mm or more and 60 mm or less.

[0030] The mixing tray 30 has a flat wall 32 with an area S3 of preferably 500 mm2 to facilitate mixing of the hair dyes. 2 More than 2500mm, preferably 2500mm 2 More preferably, 5000 mm2 From the viewpoint of reducing the environmental load, the area S3 of the flat wall portion 32 is preferably 15000 mm 2 Less than or equal to 12000mm, more preferably 2 Less than 10,000 mm, more preferably 2 Taking the above into account, the area S3 of the flat wall 32 of the mixing tray 30 is preferably 500 mm 2 More than 15000mm 2 Less than or equal to 2500 mm, preferably less than 2500 mm 2 More than 12000mm 2 Less than 5000 mm, more preferably 2 More than 10000mm 2 The following is the result.

[0031] The packaging box 10 of this embodiment is formed using one blank 50 shown in FIG. 4. Such a blank 50 can be easily obtained by, for example, punching and cutting a sheet of paperboard so that the packaging box 10 has a predetermined shape when unfolded. In addition, the blank 50 is provided with fold lines 3a to 3l and slits at appropriate locations by applying compression grooves, folding tendon processing, slit processing, etc., to the blank 50, so that the packaging box 10 can be easily assembled to have a desired three-dimensional shape described later. Even when the blank 50 is horizontally extended in a cantilever shape by gripping the side edge, it has enough shape-retaining rigidity and elasticity to easily maintain a smoothly curved state without bending, and also has enough deformability to easily be folded by hand.

[0032] As shown in FIG. 4, the blank 50 of this embodiment has a shape that is long in one direction, and has a longitudinal direction A and an orthogonal direction B perpendicular to the longitudinal direction. The blank 50 has a front portion forming plate 34, a back portion forming plate 35, and side portion forming plates 36, 37, which are partitioned by folding lines. The side portion forming plates 36, 37 are connected to both the left and right sides of the front portion forming plate 34 via folding lines 3h, 3i. The front upper surface flap forming plate 41 and the front lower surface flap forming plate 45 are connected to both the top and bottom sides of the orthogonal direction B of the front portion forming plate 34 via folding lines 3d, 3i. The upper surface side flap forming plate 38 and the lower surface side flap forming plate 42 are connected to both the top and bottom sides of the orthogonal direction B of the side portion forming plate 36 via folding lines 3a, 3e. An upper side flap forming plate 39 and a lower side flap forming plate 43 are connected to both the upper and lower sides of the side surface forming plate 37 in the orthogonal direction B via fold lines 3b, 3f. A rear upper flap forming plate 40 and a rear lower flap forming plate 44 are connected to both the upper and lower sides of the back surface forming plate 35 in the orthogonal direction B via fold lines 3c, 3g. A glue portion 82r is connected to the back surface forming plate 35 on the opposite side to the side surface forming plate 37 via a fold line 3l. Openings (not shown) are provided in the side surface forming plate 36, the front surface forming plate 34, and the side surface forming plate 37, and the transparent sheet 27 is provided so as to cover the openings.

[0035] A method for assembling the packaging box 10 will be described using the blank 50 shown in Fig. 4. The joining performed when assembling the packaging box 10 from the blank 50 shown in Fig. 4 can be performed by using a known joining means such as an adhesive. First, the fold lines 3h and 3j are folded at right angles so that the side surface forming plates 36 and 37 stand up from the front surface forming plate 34. Next, the back surface forming plate 35 is folded at right angles along the fold line 3k. Then, the glue tab 82r is folded along the fold line 3l to overlap the side surface forming plate 36 and join to the inner surface of the side surface forming plate 36. Next, the upper side flap forming plate 38 and the upper side flap forming plate 39 are folded along the fold lines 3a and 3b, and then the rear upper flap forming plate 40 is folded along the fold line 3c. Then, the front upper flap forming plate 41 is folded along the fold line 3d to be overlapped with the rear upper flap forming plate 40 and joined to the inner surface of the front upper flap forming plate 41. Next, the lower side flap forming plate 42 and the lower side flap forming plate 43 are folded along the fold lines 3e and 3f, and then the front lower flap forming plate 45 is folded along the fold line 3i. Then, the rear lower flap forming plate 44 is folded along the fold line 3g to be overlapped with the front lower flap forming plate 45 and joined to the inner surface of the rear lower flap forming plate 44. That is, the openings formed on the edge sides of the front portion forming plate 34, the side portion forming plates 36, 37 and the back portion forming plate 35 are closed by an upper side flap forming plate 38, an upper side flap forming plate 39, a rear upper side flap forming plate 40 and a front upper side flap forming plate 41, as well as a lower side flap forming plate 42, a lower side flap forming plate 43, a rear lower flap forming plate 44 and a front lower flap forming plate 45. In this manner, the packaging box 10 of the present embodiment is assembled. The packaged product 1 of the present embodiment is in a pre-use state (pre-opened state) with the storage containers 4a, 4b housed in the packaging box 10, and is distributed in this state.

[0036] The packaging box for hair dye of the present invention is not limited to the embodiment shown in the above-mentioned Figures 1 to 4. Another embodiment of the packaging box for hair dye of the present invention will be described below.

For components that are not particularly described, the description of the embodiment shown in Figures 1 to 4 will be applied as appropriate.

[0037] The mixing tray 30 in the above embodiment has only a pair of side upright walls 23, 24 facing each other in the depth direction X1 around the flat wall 32, but the manner in which the upright walls are provided around the flat wall 32 is not limited to this. For example, as shown in FIG. 5(a), the mixing tray 30 may have a pair of second upright walls 25, 25 facing each other in the width direction Y1. More specifically, in addition to the pair of upright walls 33, the mixing tray 30 may have another pair of second upright walls 25, 25 facing each other. By having the second upright walls 25, it is possible to further reduce unintended scattering and leakage when the hair dye is mixed. It is more preferable that the pair of upright walls 33 and the pair of second upright walls 25 form a peripheral wall surrounding the flat wall 32 from the viewpoint of further reducing unintended scattering and leakage when the hair dye is mixed. The second upright wall portions 25, 25 may be formed, for example, by bending the flat wall portion 32. When the second upright wall portions 25, 25 are formed by bending, it is preferable to form folding guide lines such as creases to facilitate folding. To make the mixing tray 30 have the second upright walls 25, 25, for example, in addition to the above-mentioned first portion 52 and second portions 53, 54, third portions 55 that become the second upright walls 25 are additionally provided on both sides of the first portion 52 in the direction B intersecting with the longitudinal direction A that is the direction connecting the second portions 53, 54 in the portion surrounded by the cutting guide line FL in the blank 50. For convenience, an example of the third portion 55 is shown in Fig. 4(a).

[0038] From the viewpoint of further suppressing the seepage of the hair dye, it is preferable that the transparent sheet 27 is disposed on the rising portion 29 of the second standing wall portions 25, 25. In other words, by disposing the transparent sheet 27 across the flat wall portion 32 and the second standing wall portions 25, 25, the seepage of the hair dye can be further suppressed when the hair dye is mixed.

[0039] As shown in FIG. 5(b), the mixing tray 30 may have a configuration in which the second standing wall portion 25 and the side standing wall portions 23, 24 can be engaged with each other. Specifically, the side standing wall portions 23, 24 may have engaged portions 6, 6, and the second standing wall portions 25, 25 may have locking pieces 7, 7 protruding from the second standing wall portion 25. The engaged portions 6, 6 are slits extending along the thickness direction Z1. With this configuration, for example, when the flat wall portion 32 is folded to form the second standing wall portions 25, 25, the locking pieces 7, 7 are inserted into the engaged portions 6, 6 of the side standing wall portions 23, 24, and the second standing wall portion 25 is fixed to the side standing wall portions 23, 24 (see FIG. 5(b)). In this way, the standing state of the second standing wall portions 25, 25 can be stably maintained. In such a configuration, it is preferable that the blank 50 is provided in advance with the locking piece 7 and the engaged portion 6, as shown in FIG. 4(b).
