Description

[Technical field]

[0001] The present invention relates to a blister container. [Background technology]

[0002] 2. Description of the Related Art Conventionally, it has been known to use a container housing that houses a plurality of agents constituting a hair cosmetic product as a mixing tray for mixing the plurality of agents immediately before use. For example, Patent Document 1 discloses a hair dye tray having two recesses formed therein in which the bottoms of two tube containers are placed when the two tube containers are stored side by side.

[0003] Patent Document 2 discloses a tray for hair cosmetics in which a storage space for hair cosmetics is formed by a bottom wall and a side wall extending from the periphery of the bottom wall to surround its upper surface, the side wall forming an inclined plane inclined at a predetermined angle from the upper surface of the bottom wall, and a step is formed at the upper end of the inclined plane.

[0004] Also, blister containers have been known as transparent or translucent three-dimensional resin containers that are three-dimensionally molded to have a recess for accommodating contents and have a display section so that the package insert of the contents can be seen or have an improved design and decorative effect. Patent Document 3 discloses a blister package in which a sheet having a recess for accommodating a packaged item has a back surface portion connected to an opening of the recess and perpendicular to the depth direction of the recess, and a bottom surface portion connected to the back surface portion and spaced from the recess in a first direction perpendicular to the depth direction, the bottom surface portion being parallel to a second direction perpendicular to both the depth direction of the recess and the first direction, and constituting at least a part of one or more contact portions included in an imaginary plane intersecting the first direction.

[0005] [Patent Document 1] Patent No. 4949955 [Patent Document 2] Patent No. 5528178 [Patent Document 3] JP 2018-052576 A Summary of the Invention [Problem to be solved by the invention]

[0006] The trays of Patent Documents 1 and 2 have both a function of accommodating containers containing multiple agents and a function as a tray for mixing the agents contained in each of the containers. However, when the tray and the multiple containers are distributed to the market, it is common to further package the tray containing the multiple containers in an outer box. In this respect, there is room for improvement from the viewpoint of reducing the environmental load. The blister container of Patent Document 3 is provided with the abutment portion, so that it can stand stably. The fact that the blister container can stand on its own is considered to contribute to efficient distribution because the blister container attracts attention from consumers when it is displayed on a shelf. However, the blister container of Patent Document 3 is not intended as a tray for mixing agents, and no consideration has been given to the operability when used as such a tray.

[0007] Therefore, the present invention relates to a blister container that can reduce the environmental impact, function as a mixing tray, and can stably maintain a self-supporting posture that contributes to improving distribution efficiency. [Means for solving the problem]

[0008] The present invention relates to a blister container comprising a container holder made of synthetic resin that forms a storage section in which multiple inner containers each contain multiple agents that make up a hair cosmetic product, and a lid sheet that closes the opening of the container holder. In one embodiment, it is preferable that the container holder can be used as a mixing tray for the multiple agents when the lid sheet is separated. In one embodiment, the blister container preferably has a first grounding portion on the housing portion side and a second grounding portion on the lid sheet side in a side view. In one embodiment, it is preferable that the device be self-supporting with the first grounding portion and the second grounding portion in contact with the placement surface. In one embodiment, it is preferable that the outer surface of the container housing and the inner surface of the housing portion have different surface roughnesses. Effect of the Invention

[0009] The blister container of the present invention can reduce the environmental impact, function as a mixing tray, and can stably maintain a self-supporting position that contributes to improving distribution efficiency. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] The blister container of the present invention will now be described based on its preferred embodiments. Fig. 1 shows one embodiment of the blister container of the present invention (hereinafter also referred to as "this embodiment"). As shown in FIG. 1, the blister container 1A of this embodiment comprises a container holder 2A made of synthetic resin that forms a storage section 21 in which two inner containers 4a, 4b are stored, and a lid sheet 3 that closes the opening of the container holder 2A.

[0012] The blister container 1A of this embodiment has a hexahedral shape that is long in one direction, and has a longitudinal direction Y and a width direction X perpendicular to the longitudinal direction Y. The longitudinal direction of the blister container 1A coincides with the longitudinal direction of the container housing 2A, and the width direction of the blister container 1A coincides with the width direction of the container housing 2A. The blister container 1A also has a thickness direction Z perpendicular to both the longitudinal direction Y and the width direction X. The thickness direction Z is the direction from one main surface to the other main surface when the length between opposing main surfaces of the container housing 2A described below is taken as the thickness.

[0013] The container housing 2A is a box-shaped resin container having one main surface open, which is three-dimensionally formed by vacuum forming using a plastic film or a plastic sheet. The container housing 2A of this embodiment is a flat hexahedral resin container having one main surface open. The container housing 2A uses a transparent or semi-transparent plastic film or sheet, so that the inner containers 4a, 4b and other contents such as one or more bag-like containers, combs, instruction manuals, etc. housed in the housing section 21 can be directly viewed. In addition, the container housing 2A is designed so that the package insert, decoration, etc. displayed on the surface of the lid sheet 3 attached to close the opening, facing the housing section 21, can be viewed through the container housing 2A, enhancing the display effect and decorative effect.

[0014] The container housing 2A has a flat wall portion 22 arranged opposite to the lid sheet 3 at a distance in the thickness direction Z. In this embodiment, the flat wall portion 22 is parallel to the lid sheet 3. As described later, the flat wall portion 22 is a portion that forms the bottom surface of the tray when the container housing 2A is used as a mixing tray for the agents contained in the inner containers 4a and 4b. The container housing 2A also has a peripheral wall portion 23 that is located around the flat wall portion 22 and extends in the thickness direction of the container housing 2A. In the container housing 2A, the space surrounded by the flat wall portion 22 and the peripheral wall portion 23 serves as the storage portion 21 that stores the inner containers 4a and 4b and other contents described above. That is, in the container housing 2A, the recess formed by the flat wall portion 22 and the peripheral wall portion 23 serves as the storage portion 21.

[0015] FIG. 3(a) shows the blister container 1A placed on a horizontal surface (hereinafter also referred to as the "placing surface 50") with the flat wall 22 of the container carrier 2A as the bottom surface (hereinafter also referred to as the "flat state"). In this state, the thickness direction Z of the blister container 1A coincides with the vertical direction. As described below, this blister container 1A has a first grounding portion 51 at a corner between the flat wall 22 and the peripheral wall 23. The corner is a boundary between the flat wall 22 and the peripheral wall 23, and the flat wall 22 and the peripheral wall 23 are continuous with each other through the corner. In the flat state, the longitudinal direction Y of the blister container 1A coincides with the horizontal direction (not shown).

[0016] As shown in Figures 1(a) and (b), the blister container 1A of this embodiment can stand on its own with the longitudinal direction Y aligned along the vertical direction Y1. Hereinafter, this state will be referred to as the "self-supporting state." In the self-supporting state, the thickness direction Z of the blister container 1A is aligned along the front-rear direction Z1 (depth direction) perpendicular to both the longitudinal direction Y and the width direction X (see Figure 2). In this front-rear direction Z1, the flat wall portion 22 side is the rear side, and the opposite side of the flat wall portion 22, i.e., the lid sheet 3 side, is the front side. Details of the blister container 1A in the self-supporting state will be described later.

[0017] In this embodiment, six scales 221 are formed on the outer surface of the flat wall portion 22 at equal intervals in the longitudinal direction Y, and two scales are formed at intervals in the width direction X. The scales 221 are lines extending along the width direction X, and function as a guide for measuring the amount of the multiple agents dispensed. The scales 221 may be formed as recesses or protrusions when the container housing 2A is three-dimensionally molded, or may be formed on the inner or outer surface of the housing portion 21 by printing.

[0018] In the freestanding state shown in Fig. 4, one end of the container housing 2A in the longitudinal direction Y is in contact with the placement surface 50, and the other end of the container housing 2A in the longitudinal direction Y is spaced apart from the placement surface 50 in the vertical direction. At one end of the container housing 2A in the longitudinal direction Y, the flat wall portion 22 has a rear edge portion 22a extending in the width direction X, a front edge portion 22b facing the rear edge portion 22a and extending in the width direction X, and a pair of side edges 22c, 22c located between the rear edge portion 22a and the front edge portion 22b and extending along the longitudinal direction Y of the flat wall portion 22 (see Fig. 2). In the container housing 2A of this embodiment, the side edges 22c, 22c of the flat wall portion 22 extend linearly along the longitudinal direction Y.

[0019] As described above, the peripheral wall portion 23 is located around the flat wall portion 22 and extends in the thickness direction Z from the peripheral edge of the flat wall portion 22. Specifically, the peripheral wall portion 23 has a rear wall portion 23a that is continuous with the rear end edge portion 22a of the flat wall portion 22 in the thickness direction Z, a front wall portion 23b that extends in the thickness direction Z from the front end edge portion 22b of the flat wall portion 22, and side wall portions 23c, 23c that extend in the thickness direction Z from the side end edges 22c, 22c of the flat wall portion 22. In the flat-laid state, the peripheral wall portion 23 has a tapered shape in which the horizontal cross section expands from the flat wall portion 22 toward the opening of the container housing 2A.

[0020] The rear wall 23a, the front wall 23b, and the side walls 23c, 23c of the peripheral wall 23 are connected in a ring shape at their edge portions opposite the flat wall 22 in the thickness direction Z to form the opening end of the container housing 2A. With regard to such opposite edge portions, the edge portion of the rear wall 23a is also referred to as the "lid-side rear edge 24a," the edge portion of the front wall 23b is also referred to as the "lid-side front edge 24b," and the edge portions of the side walls 23c, 23c are also referred to as the "lid-side both side edges 24c, 24c."

[0021] The container housing 2A has a storage section 21 in which a plurality of inner containers 4a, 4b are stored. In the container housing 2A of this embodiment, two inner containers 4a, 4b are stored in the storage section 21. One inner container 4a is a tube container in which a first agent constituting the hair cosmetic is stored, and the other inner container 4b is a tube container in which a second agent constituting the hair cosmetic is stored. In this embodiment, the two inner containers 4a, 4b are stored in the storage section 21, but other inner containers may also be stored. In the blister container 1A of this embodiment, the inner containers 4a and 4b are accommodated in the accommodation section 21 with the longitudinal direction of the inner containers 4a and 4b aligned with the longitudinal direction Y of the blister container 1A.

[0022] Each of the inner containers 4a and 4b of this embodiment includes a tube body 40 in which the agent is contained. Each of the tube bodies 40 includes a body portion 42 made of a cylindrical tube body made of synthetic resin, an end seal portion 43 formed between the inner surfaces at one longitudinal end of the tube body by a known method such as heat fusion or ultrasonic waves, and a cap portion 41 detachably attached to a neck portion (not shown) connected to the other longitudinal end of the tube body (see FIG. 1(a)).

[0023] The container housing 2A has flange portions 25 extending outward in the longitudinal direction Y and the width direction X from the periphery of the opening of the container housing 2A (see FIG. 2). Specifically, the flange portion 25 has a rear flange portion 25a extending outward in the longitudinal direction Y from the lid-side rear end edge portion 24a, a front flange portion 25b extending outward in the longitudinal direction Y from the lid-side front end edge portion 24b, and a pair of side flange portions 25c, 25c extending outward in the width direction Y from the lid-side both side edges 24c, 24c. The rear flange portion 25a, the front flange portion 25b and the pair of side flange portions 25c, 25c are formed so as to surround the four sides of the periphery of the rectangular opening of the container housing 2A.

[0024] In this embodiment, the front flange portion 25b is located vertically above the lid sheet 3 in a freestanding state. The front flange portion 25b has a hanging opening 27 at the center in the width direction X. The blister container 1A of this embodiment can be displayed in a state where it is hung from a hanging device provided in a sales area, for example, by hanging the hanging opening 27 on the hanging device.

[0025] As shown in Fig. 4(b), the rear flange portion 25a in the container housing 2A of the present embodiment has a tip portion folded back inward in the longitudinal direction Y to form a rear locking portion 26a having a U-shaped or C-shaped cross section along the longitudinal direction Y. Also, as shown in Fig. 3(b), the side flange portions 25c, 25c in the container housing 2A of the present embodiment have tip portions folded back inward in the width direction X to form side slide locking portions 26c, 26c having a U-shaped or C-shaped cross section along the width direction X. These locking portions 26a, 26c, 26c are arranged along three edges of the rectangular opening end of the container housing 2A in a self-supporting state, excluding the edge along the front flange portion 25b. In the container housing 2 having such locking portions, the lid sheet 3 is inserted between the side flange portions 25c, 25c and the side slide locking portions 26c, 26c formed by folding back, and one end of the lid sheet 3 in the longitudinal direction X is inserted between the rear flange portion 25a and the rear locking portion 26a formed by folding back, and is fixed to the container housing 2. As a result, the opening of the container housing 2A is closed by the lid sheet 3. In the blister container 1A of this embodiment, the opening of the container holder 2A can be opened by sliding the lid sheet 3 along the longitudinal direction X toward the front flange portion 25b.

[0026] In the blister container 1A of this embodiment, the lid sheet 3 is fixed between the rear engagement portion 26a and the rear flange portion 25a, and between the side slide engagement portions 26c, 26c and the side flange portions 25c, 25c by adhesive tape (not shown) while closing the opening of the container holder 2A. In the blister container 1A of this embodiment, product information about the product is displayed on a surface 3a of the lid sheet 3 opposite to the surface facing the storage section 21, i.e., on the outer surface 3a of the lid sheet 3. The product information is information that is usually displayed on a packaging container such as an outer box of a product placed in the distribution process, such as the product name, the contents and their quantities contained in the blister container 1A, hair color, finished image, operating procedures, warning labels, and a list of all ingredients of the contents (package insert). The lid sheet 3 in this embodiment is made of paper, but the material of the lid sheet 3 is not limited to this and may be, for example, plastic, metal, etc., or a combination of these.

[0027] The blister container 1A of this embodiment comprises a container housing 2A having a storage section 21 in which inner containers 4a, 4b and other contents are stored, and a lid sheet 3 that closes an opening in the container housing 2A that communicates with the storage section 21. The lid sheet 3 has product information displayed on its outer surface 3a. Therefore, the blister container 1A functions as a packaging container for distributing the inner containers 4a, 4b and other contents to the market, eliminating the need for an outer box or the like for packaging them from the outside.

[0028] As described above, the blister container 1A of this embodiment is capable of standing on its own (see FIG. 4(a)). When the blister container 1A is viewed from the side in a standing state, the blister container 1A has a first grounding portion 51 and a second grounding portion 52 at one end in the longitudinal direction Y that is in contact with the mounting surface 50. In the side view, the first grounding portion is located on the housing portion 21 side, and the second grounding portion 52 is located on the lid sheet 3 side. These grounding portions 51, 52 are portions that come into contact with the mounting surface 50 when the blister container 1A is in a standing state, and the blister container 1A is capable of standing on its own with the grounding portions 51, 52 in contact with the mounting surface 50.

[0029] The first grounding portion 51 is formed by one end of the container housing 2A in the longitudinal direction Y. The second grounding portion 52 can be formed by one end of the container housing 2A in the longitudinal direction Y or one end of the lid sheet 3 in the longitudinal direction Y. In the blister container 1A of this embodiment, a first grounding portion 51 is formed at the corner between the rear end edge portion 22a of the flat wall portion 22 and the rear wall portion 23a of the peripheral wall portion 23, and a second grounding portion is formed on the rear flange portion 25a. With this configuration, there is no need to provide a separate grounding portion for the blister container 1A with the placement surface 50, and the appearance can be made compact.

[0030] In this embodiment, the first grounding portion 51 and the second grounding portion 52 each extend in the width direction X and are parallel to each other. This allows the blister container 1A to be more stable in a self-supporting state. The blister container 1A in the self-supporting state is longer in the vertical direction (height direction) than when it is laid flat. This makes it easier for consumers to see the surface 3a of the lid sheet 3 opposite the storage portion 21 when the blister container 1A is displayed on a display shelf in a self-supporting state.

[0031] The container housing 2A can be used as a mixing tray for the multiple agents contained in the inner containers 4a, 4b when the cover sheet 3 is separated. That is, by separating the cover sheet 3 from the blister container 1A, the container housing 2A can be used as a mixing tray when the opening is opened and the inner containers 4a, 4b and other contents are removed through the opening. In this case, the container housing 2A is used with the outer surface of the flat wall portion 22 as the bottom, and the multiple agents are mixed in the space forming the housing portion 21.

[0032] When the container housing 2A of this embodiment is used as a mixing tray, the scale 221 formed on the flat wall portion 22 functions as a guide for measuring the amount of multiple agents dispensed. That is, since the two types of agents accommodated in the inner containers 4a and 4b can be dispensed in precise amounts, the agents can be mixed in a precise ratio, and operability is excellent.

[0033] In the blister container 1A, the outer surface of the container housing 2A and the inner surface of the housing portion 21 have different surface roughness. This allows the container housing 2A to achieve both stability in a self-supporting state and ease of use when mixing multiple agents. More specifically, by making the surface roughness of the outer surface of the container housing 2A rougher than that of the inner surface, it is possible to increase the frictional force generated between the container housing 2A and the placement surface 50, and to improve the ease of use when mixing multiple agents on a smooth inner surface.

[0034] As described above, in the blister container 1A of this embodiment, the first ground contact portion 51 is formed at the corner between the rear end edge portion 22a of the flat wall portion 22 and the rear wall portion 23a of the peripheral wall portion 23, and the second ground contact portion 52 is formed on the rear flange portion 25a. That is, since the first ground contact portion 51 and the second ground contact portion 52 have a surface roughness greater than that of the inner surface of the container housing body 2A, the frictional force generated between the first ground contact portion 51 and the second ground contact portion 52 can be increased, making them less likely to slip on the mounting surface 50.

[0035] In order to better achieve a balance between the self-supporting ability of blister container 1A and the operability of container housing 2A as a mixing tray, the difference in surface roughness (arithmetic mean roughness Ra) of the outer surface of container housing 2A and the surface roughness (arithmetic mean roughness Ra) of the inner surface of housing section 21 is preferably 1 μm or more, more preferably 5 μm or more, and preferably 50 μm or less, more preferably 25 μm or less, and preferably 1 μm or more and 50 μm or less, and more preferably 5 μm or more and 25 μm or less. To prevent the blister container 1A from slipping on the placement surface 50, the surface roughness (arithmetic mean roughness Ra) of the outer surface of the container package 2A is preferably 5 μm or more, and more preferably 10 μm or more. Furthermore, when the container housing 2A is used as a mixing tray, from the viewpoint of facilitating mixing of multiple agents within the housing section 21, the surface roughness (arithmetic mean roughness Ra) of the inner surface of the housing section 21 is preferably 4 μm or less, and more preferably 2 μm or less.

[0036] [Method of measuring surface roughness] The surface roughness (arithmetic mean roughness Ra) of the outer surface of the container housing 2A and the inner surface of the housing portion 21 is measured in accordance with JIS B 0601. The surface roughness is measured using a stylus-type surface roughness meter (SV-C4000CNC, manufactured by Mitoyo Co., Ltd.) at a measurement speed of 0.05 mm / s.

[0037] The blister container 1A of this embodiment functions as a packaging container for the inner containers 4a, 4b, and the container housing 2A also functions as a mixing tray. Therefore, according to the blister container 1A of this embodiment, when distributing it on the market, it is not necessary to provide a separate outer box or mixing tray, so that the overall amount of synthetic resin used can be reduced, which contributes to reducing the environmental load. In addition, since the blister container 1A of the present invention is self-supporting, the display space required can be reduced. This allows a large number of blister containers 1A to be displayed. Furthermore, the self-supporting ability makes it easier to visually confirm product information. In particular, the visibility of the outer surface 3a of the lid sheet 3 is excellent. Thus, the self-supporting ability of the blister container 1A of this embodiment contributes to improving distribution efficiency.

[0038] From the viewpoint of further improving the visibility of the above-mentioned product information, it is preferable that the blister container 1A is inclined in a self-supporting state with the outer surface 3a of the lid sheet 3 facing obliquely upward. In such an inclined state, it is preferable that the intersection points La, Lb between the placement surface 50 and perpendicular lines drawn from the centers of gravity Ga, Gb of the inner containers 4a, 4b, respectively, to the placement surface 50 are between the first grounding portion 51 and the second grounding portion 52 (see FIG. 4(a)). Such an inclined state of blister container 1A is preferable because, when blister container 1A is displayed in a free-standing state, it can further improve the visibility of outer surface 3a of lid sheet 3. Furthermore, because the intersections La, Lb are present between first grounding portion 51 and second grounding portion 52, even when blister container 1A is in the above-mentioned inclined state, blister container 1A can be prevented from falling toward flat wall portion 22 due to the weight of inner containers 4a, 4b, so that inclined blister container 1A can be made to stand upright more stably.

[0039] From the viewpoint of making the blister container 1A more stable in its freestanding state, the inclination angle θ of the second grounding portion 52 in the freestanding state (see FIG. 4(b)) is preferably 60° or more, more preferably 75° or more, and is preferably 90° or less, more preferably 85° or less, and is preferably 60° or more and 90° or less, and more preferably 75° or more and 85° or less. With this configuration, the intersection points La and Lb between the mounting surface 50 and the perpendicular lines drawn from the centers of gravity Ga and Gb of the inner containers 4a and 4b, respectively, to the mounting surface 50 are likely to be located between the first grounding portion 51 and the second grounding portion 52. The inclination angle θ is the angle of the second grounding portion 52 with respect to the mounting surface 50 when the blister container 1A in the freestanding state is viewed from the side.

[0040] In the blister container 1A, the inner containers 4a and 4b are tube containers (see Fig. 1(b) and Fig. 2). The container carrier 2A of this embodiment has a plurality of cap recesses 53a and 53b for accommodating the cap parts 41 of the tube containers, and it is preferable that the outer surface sides of the cap recesses 53a and 53b form a plurality of first grounding parts 51 spaced apart from each other. This makes it possible to make the free-standing state of the blister container 1A more stable.

[0041] More specifically, in the container carrier 2A of this embodiment, cap recesses 53a, 53b capable of accommodating the cap portions 41 of the inner containers 4a, 4b are formed in the rounded corners between the rear end edge portion 22a of the flat wall portion 22 and the rear wall portion 23a of the peripheral wall portion 23. The cap recesses 53a, 53b are spaced apart from each other in the width direction X, and the outer sides of each of them form the first grounding portion 51. In addition, in the blister container 1A in a self-supporting state, the portion between the rear end edge portion 22a of the flat wall portion 22 and the rear wall portion 23a of the peripheral wall portion 23, which is between the cap recesses 53a, 53b in the width direction X, is in a state of being floated above the placement surface 50. In this blister container 1A, the cap portions 41 of the inner containers 4a, 4b accommodated in the accommodation portion 21 are accommodated in the cap recesses 53a, 53b, so that the inner containers 4a, 4b are fixed inside the accommodation portion 21, thereby further preventing the inner containers 4a, 4b from colliding with each other and being damaged during transportation, etc. In addition, because the first grounding portions 51 (cap recesses 53a, 53b) to which the weight of the inner containers 4a, 4b is likely to be applied are spaced apart in the width direction X, the load due to the weight can be dispersed, and the self-supporting state of the blister container 1A can be further stabilized. In order to further enhance the above-mentioned effect, when the container housing 2A is viewed from the outer surface of the flat wall portion 22, the separation distance L in the width direction X between the cap recesses 53a, 53b is preferably 5 mm or more and 30 mm or less, more preferably 10 mm or more and 20 mm or less.

[0042] The container housing 2A preferably has rounded corners at least on one end side in the height direction (longitudinal direction Y) in a freestanding state. As shown in FIG. 4(a), the container housing 2A of this embodiment has rounded corners at the upper end in the longitudinal direction Y in a freestanding state, i.e., at one end in the longitudinal direction Y in a flat laid state. More specifically, the corners between the front end edge 22b and the front wall 23b of the flat wall 22 are rounded. This makes it easier for a stirring spatula or the like to enter the corners when the container housing 2A is used as a mixing tray, and the workability of mixing a plurality of agents can be further improved. In order to facilitate the mixing of multiple agents while at the same time making the storage section 21 compact, the radius of curvature of the rounded corners is preferably 5 mm or more, more preferably 10 mm or more, and is preferably 30 mm or less, more preferably 20 mm or less, and is preferably 5 mm or more and 30 mm or less, and more preferably 10 mm or more and 20 mm or less.

[0043] From the viewpoint of achieving a good balance between the storage capacity of the storage unit 21 and the ease of use when used as a mixing tray, it is preferable that the dimensions of the storage unit 21 and the inner containers 4a, 4b be within the following ranges. The depth (length in the thickness direction Z) of the storage section 21 consisting of a recess is preferably 1 to 2 times, more preferably 1.1 to 1.5 times, the thickness of the inner containers 4a, 4b in the stored state. The thickness of the inner containers 4a, 4b in the stored state is the maximum length in the thickness direction Z of the inner containers 4a, 4b when they are stored in the storage section 21. The length of the flat wall portion 22 in the longitudinal direction Y is preferably 1 to 1.3 times, and more preferably 1.05 to 1.2 times, the length of the inner containers 4a, 4b in the longitudinal direction Y. The length of the inner containers 4a, 4b in the contained state in the longitudinal direction Y is the maximum length of the inner containers 4a, 4b in the longitudinal direction Y when they are contained in the container section 21. The above-mentioned dimensions of the flat wall portion 22 are dimensional values ​​that do not include the rounded portions, if the corners formed between the flat wall portion 22 and the peripheral wall portion 23 are rounded.

[0044] It is preferable that the lid sheet 3 has usage information including a method of using the container housing 2A as a mixing tray displayed on the outer surface 3b (not shown). This eliminates the need for a separate instruction manual, and therefore eliminates the need to provide separate paper or the like on which the instruction manual is written, thereby further conserving resources.

[0045] Next, another embodiment of the blister container of the present invention will be described. In the following description, components different from the embodiment shown in Figures 1 to 4 will be mainly described, and similar components will be given the same reference numerals and description will be omitted. For components that are not particularly described, the description of the above embodiment will be applied as appropriate. In the following description, components common to different embodiments will be denoted by the same reference numerals and description thereof will be omitted. In this case, the description of the common components will also be applied as appropriate.

[0046] In the container housing 2A of the above-mentioned embodiment, the flat wall portion 22 arranged facing the lid sheet 3 at a distance in the thickness direction Z is parallel to the lid sheet 3, but is not limited to such a configuration. In the blister container 1B shown in Figs. 5(a) and (b), the flat wall portion 22 is inclined with respect to the lid sheet 3 so that the distance between the lid sheet 3 and the flat wall portion 22 in the thickness direction Z gradually narrows toward the front wall portion 23b in the longitudinal direction Y. As a result, when the blister container 1B is in a self-supporting state in which the outer surface 3a of the lid sheet 3 is in a tilted state facing diagonally upward, the longitudinal direction of the inner containers 4a, 4b accommodated in the accommodation portion 21 approaches the vertical direction, so that the centers of gravity Ga, Gb of the inner containers 4a, 4b are more stabilized and the self-supporting state can be easily maintained. As a result, the blister container 1B is less likely to fall over, and the self-supporting state is more stable.

[0047] In the blister container 1B of this embodiment, the first ground contact portion 51 is formed by the edge of the rear wall portion 23a of the peripheral wall portion 23 on the flat wall portion 22 side. The edge extends in the width direction X. That is, the first ground contact portion 51 of this embodiment is continuous with the blister container 1A in the width direction X.

[0048] The blister containers 1A, 1B in the above-described embodiments can be three-dimensionally molded to have a recess (containing portion 21) for containing the contents, thereby manufacturing the container housings 2A, 2B. The blister containers 1A, 1B are manufactured by putting contents such as inner containers 4a, 4b into resin containers (container housings 2A, 2B) that are three-dimensionally molded by vacuum forming using a plastic sheet, and then covering the openings of the resin containers with a lid sheet 3.

[0049] From the viewpoint of achieving both the self-supporting property of the blister containers 1A, 1B and the ease of use when used as a mixing tray, the thickness of the plastic sheet used for the container holder 2A is preferably 0.2 mm or more and 0.5 mm or less.

[0050] The present invention is not limited to the above-described embodiments and may be modified as appropriate. In addition, the above-described embodiments may be combined. For example, although the containers in the above-described embodiment are self-supporting containers, they may be used in a state other than the self-supporting state. For example, a hanging hole may be provided in the front flange of the container holder, and the container may be displayed in a state where it is hung from a hanging tool through the hole. In the above-described embodiment, the lid sheet 3 is fixed by adhesive tape in a state in which it is slidably engaged with the engaging portions formed on the flange portions 25 of the container housing 2A, 2B, but instead, as shown in Fig. 6, the lid sheet 3C may be sealed to the flange portion 25 of the container housing 2C by a known method such as heat fusion or ultrasonic waves. The flange portion 25 shown in Fig. 6 has a rear flange portion 25a, a front flange portion 25b, and a pair of side flange portions 25c, 25c that surround the four sides of the rectangular opening periphery of the container housing 2C and have substantially the same width.

[0051] Further, the container housing 2A, 2B, and 2C in the above-mentioned embodiment are flat hexahedral containers with one main surface open, but instead, as shown in Figs. 7(a) and (b), they may be bowl-shaped containers with one main surface open and a flat bottom surface. The container housing 2D of the blister container 1D shown in Figs. 7(a) and (b) has a flat wall portion 22D corresponding to the bottom surface portion and a substantially cylindrical peripheral wall portion 23D located around the flat wall portion 22D and extending in the thickness direction of the container housing 2D. In the container housing 2D, a bowl-shaped space surrounded by the flat wall portion 22D and the peripheral wall portion 23D is the housing portion 21D. In addition, the edge portion of the peripheral wall portion 23D opposite to the flat wall portion 22D forms a circular opening periphery. The container housing 2D has a flange portion 25D extending outward from the opening periphery. A lid sheet 3D is sealed to the flange portion 25D by a known method such as heat fusion or ultrasonic sealing.

[0052] In the container housing 2D, the housing section 21D can house the inner containers 4a, 4b and other contents as described above, similarly to the housing section 21 of the above-mentioned embodiment. In addition, by separating the cover sheet 3D from the blister container 1D, the opening of the container housing 2D is opened, and the container housing 2D can be used as a mixing tray after the inner containers 4a, 4b and other contents are removed through the opening. In this case, the container housing 2D is used with the outer surface of the flat wall portion 22D as the bottom surface, and multiple agents are mixed in the space forming the housing section 21D. The container housing 2D allows stirring work while running a spatula or the like along the inner surface of the cylindrical peripheral wall portion 23D, which further improves the workability of mixing multiple agents. In addition, the container housing 2D has cap recesses 53a, 53b capable of housing the caps 41 of the inner containers 4a, 4b at the corners between the flat wall 22D and the peripheral wall 23D. The cap recesses 53a, 53b are spaced apart from each other in the width direction X, and the outer sides of each recess are the first grounding parts 51D. The flange 25D of the container housing 2D has a second grounding part 52D at the end closest to the first grounding part 51D. As shown in FIG. 7(b), the blister container 1D of this embodiment can stand on its own in a state where the grounding parts 51D, 52D are in contact with the mounting surface 50 by abutting the first grounding part 51D and the second grounding part 52D against the mounting surface 50. This provides the same effect as the above-mentioned embodiment.

[0053] In addition, although the inner container in the above-described embodiment is a tube container, it may be a bag-shaped container instead. The hair cosmetic product may be a hair dye, for example, a two-component or three-component hair dye. [Explanation of symbols]
