Effects of the Invention

[0007] According to the present invention, a solid bath agent with high interestingness can be provided. [Brief explanation of the drawing]

[0008] [Figure 1] This is a perspective view showing the appearance of a solid bath additive according to one embodiment of the present invention. [Figure 2] Figure 1 is a schematic cross-sectional view showing the inside of a solid bath additive. [Figure 3] This is a perspective view of the first part.

[Figure 6] This is an explanatory diagram showing the state of toy parts floating on the surface of the water. [Figure 7] This is an explanatory diagram showing an example of how to play with the toy parts. [Figure 8] This is a schematic cross-sectional view showing a modified example of the enclosed state of the first and second parts. [Modes for carrying out the invention]

[0009] The following describes an embodiment of a solid bath additive representing one aspect of the present invention, with reference to the figures. Figure 1 is a perspective view showing the appearance of a solid bath additive 1 according to one embodiment of the present invention.

[0010] As shown in Figure 1, the solid bath additive 1 comprises a water-soluble main body 10 with a rotatable spherical outer surface 10s, and toy parts 20 consisting of a first part 21 and a second part 22 (hereinafter, when the first part 21 and the second part 22 are referred to collectively without distinction, they are called "toy parts 20").

[0011] Furthermore, a tablet-shaped sub-part 30 is enclosed adjacent to the first part part 21. The first part part 21 and the second part part 22 are made of rectangular plate members and are identical in shape. The first part part 21 and the second part part 22 are made of, for example, synthetic resin or wood, and are non-water soluble and float on liquid (bathwater 50). On the other hand, the sub-part 30, together with the main body part 10, is soluble and can change the color of the bathwater 50 (see Figure 5) to a specific color as a bath additive. Here, the outer surface 10s of the main body part 10 is made of a material that does not float on water, for example, has a rough, uneven surface. Therefore, the solid bath additive 1 is designed to sink when it is added to water (bathwater 50).

[0012] Figure 2 is a schematic cross-sectional view showing the inside of the solid bath additive 1 shown in Figure 1. As shown in Figure 2, the main body 10 contains a dye that produces a first color C1 when dissolved, and the sub-body 30 contains another dye that produces a second color C2 which is different from the first color C1. Therefore, when the solid bath additive 1 is added to the bathwater 50, as will be described later, the color at the initial stage when it begins to dissolve in the bathwater 50 is different from the color thereafter. Furthermore, the first part 21 and the second part 22 are located in the center of the main body 10. For example, the first part 21 and the second part 22 are located adjacent to each other in the center of the main body 10, flanking the center point Ce of the main body 10, without touching each other. Moreover, as shown in Figure 2, they are directly contained within the main body 10 without the use of special storage means (e.g., a case or bag).

[0013] Figure 3 is a perspective view of the first part 21, and Figure 4 is a perspective view of the second part 22.

[0014] The toy parts 20 shown in FIGS. 3 and 4 are flat plate members each depicting patterns D1 and D2 of, for example, fashionable female characters. In the illustration, only the front surface side of the toy part 20 is shown, but the same pattern may be on the back surface side or other patterns may be present. Each of the patterns D1 and D2 is a different pattern selected from a number of patterns.

[0015] Also, the toy part 20 is made of the same or the same color system (C1) as the main body part 10. In this embodiment, the part of the same color as the main body part 10, for example, the background part 28 of the character is made of the same color (C1). Note that the same color as referred to in the present invention does not mean that all the colors of the toy part 20 are the same or of the same color system, but a part of them is the same or of the same color system and can evoke a color-related association with the main body part 10. Therefore, as shown in the illustration, the background part 28 of the character may not be of the same or the same color system. For example, it may be the case of the color of the character's hair, clothing, etc. Further, for example, the toy part 20 may be configured to have a border part, and the color of this border part may be the same or of the same color system.

[0016] The first part portion 21 and the second part portion 22 are each provided with a hole portion 23. This hole portion 23 is configured, for example, as a substantially annular protrusion protruding from one short side of the toy part 20, and this protrusion portion has a through hole 23h in the part thickness direction.

[0017] FIG. 5 is an explanatory diagram showing the state where the solid bath agent 1 is put into the bath water 50. The solid bath agent 1 is configured such that the main body part 10 has a weight that sinks in water as described above. As a result, when the solid bath agent 1 is put into the bath water 50, together with the toy part 20 that floats in water, it sinks to the bottom 61 of, for example, the bathtub 60 (see FIG. 6) as shown in FIG. 5. In this sunken state, the main body part 10 melts away from its outer surface 10s.

[0018] From the outer surface 10s of the main body portion 10, the components of the first color C1 float upward, for example, together with the bubbles 18. Then, the color change of the bath water 50 starts from the water surface 50a or a place near the water surface 50a and changes to the first color C1 as the first stage. In this initial stage, the auxiliary body portion 30 has not melted out.

[0019] FIG. 6 is an explanatory view showing a state where the toy part 20 has floated on the water surface 50a. In the first stage when the solid bath agent 1 starts to dissolve, the bath water 50 becomes the first color C1. Then, as the main body portion 10 dissolves and the auxiliary body portion 30 starts to be exposed, the auxiliary body portion 30 starts to dissolve. As a result, before the toy part 20 floats on the water surface 50a, it starts to change to the second color C2 of the second stage. After the color of this second color C2 starts to appear or has appeared, as shown in FIG. 6, the toy part 20 floats. At this time, the toy part 20 floats together with the remaining portion 30a of the auxiliary body portion 30. Therefore, as shown in the drawing, the remaining portion 30a floats around the toy part 20, and the second color C2 continues to dissolve out from this remaining portion 30a.

[0020] The toy part 20 floating on the water surface 50a floats up in a state where the first part portion 21 and the second part portion 22 are separated as shown in the drawing. This is because, as described above, the first part portion 21 and the second part portion 22 are not arranged to contact each other, so the state where the two part portions 21, 22 are stuck together does not occur and they float up in a separated state. Also, before and after the timing when the toy part 20 floats, it becomes a color state of the two colors before the first color C1 and the second color C2 are completely mixed as shown in the drawing. Thereby, the appearance (floating up) of the toy part 20 is produced.

[0021] FIG. 7 is an explanatory view showing an example of how to play with the toy part 20. Since the toy part 20 has a configuration in which the first part portion 21 and the second part portion 22 are paired, as shown in FIG. 7, a strap 25 such as a chain, which is a string-like member, can be passed through the hole portion 23 to be in a connected state. The first part portion 21 and the second part portion 22 do not have a structure for directly connecting, and they can be attached to a bag or the like in a connected state via the strap 25 and played with.

[0022] Figure 8 is a schematic cross-sectional view showing a modified example of the enclosed state of the first part 21 and the second part 22. The solid bath bomb 1 shown in Figure 8 has an internal space SP formed inside it. The toy parts 20 and the sub-body part 30 are housed within this internal space SP. In this case, the sub-body part 30 is positioned between the first part 21 and the second part 22. Therefore, even in this case, the first part 21 and the second part 22 are not in contact with each other.

[0023] As described above, in the solid bath additive 1 of the above embodiment, the multiple parts of the first part section 21 and the second part section 22 are provided within the main body section 10, making it possible to play by linking the two part sections 21 and 22 together.

[0024] In the solid bath additive 1 of the above embodiment, different patterns D1 and D2 are provided on the first part 21 and the second part 22, allowing for a variety of patterns D1 and D2 to be enjoyed. Furthermore, since these different patterns D1 and D2 are selected from a large number of available patterns, for example, if patterns D1 and D2 are related to a character, it is possible to create a storyline related to the character by combining the selected patterns D1 and D2.

[0025] In the solid bath additive 1 according to the above embodiment, the first part 21 and the second part 22 are directly enclosed within the main body 10, so that both parts can be directly seen above the water surface 50a after the main body 10 has dissolved in the liquid (bathwater 50).

[0026] In the solid bath additive 1 according to the above embodiment, the first part 21 and the second part 22 are enclosed in the central part of the main body 10, so that they become visible almost simultaneously with the main body 10 almost completely dissolving. As a result, the main body 10 makes it possible to create a state in which both parts appear when the color of the bath water 50 is at its darkest due to the main body 10.

[0027] In the solid bath additive 1 according to the above embodiment, the first part 21 and the second part 22 are enclosed within the main body 10 side by side, making it possible to create the effect of both parts appearing almost simultaneously.

[0028] In the solid bath additive 1 of the above embodiment, the first part 21 and the second part 22 are enclosed within the main body 10 without touching each other, thereby preventing the two parts from sticking together. This allows the first part 21 and the second part 22 to float while separated from each other.

[0029] In the solid bath additive 1 according to the above embodiment, the first part 21 and the second part 22 are made to have the same color as the main body 10, making it possible to create an effect that emphasizes the relationship with the color of the dissolved main body 10.

[0030] In the solid bath additive 1 of the above embodiment, the main body 10 is configured to be spherical and rotatable before dissolution, so it can be rolled around and played with.

[0031] In the solid bath additive 1 of the above embodiment, the outer surface of the main body 10 has an uneven surface, making it less slippery and easier to hold. In addition, the uneven surface increases the surface area, which allows the main body 10 to dissolve more quickly.

[0032] In the solid bath additive 1 according to the above embodiment, the first part 21 and the second part 22 have a flattened shape, so when they float on the surface of the water, they can float with the flat parts on which the patterns D1 and D2 are formed facing upwards.

[0033] In the solid bath additive 1 according to the above embodiment, the first part portion 21 and the second part portion 22 are provided with holes 23 through which a strap 25 can be inserted, so that the two parts can be connected by the strap 25.

[0034] In the solid bath additive 1 of the above embodiment, the sub-body part 30, which is configured to be soluble, is enclosed within the main body part 10, so that the sub-body part emits a second color C2 in relation to the first color C1 of the main body part 10. This allows users to enjoy the change in the color of the bathwater 50. Furthermore, it is possible to create a visual effect that associates the change between the first color C1 and the second color C2 with the character of the toy part 20 through color.

[0035] Furthermore, in the solid bath additive 1 according to the above embodiment, since the sub-body portion 30 is provided adjacent to the first part portion 21 or the second part portion 22, the timing of the first part portion 21 or the second part portion 22 floating up and the timing of the sub-body portion 30 dissolving can be made to be approximately the same. As a result, the appearance of one or both of the characters of the toy parts 20 can be represented by the second color C2 of the sub-body portion 30.

[0036] Although embodiments of the present invention have been described above, the present invention can be modified as appropriate within the scope of its technical concept. For example, in the above embodiment, the solid bath additive 1 is a spherical body part 10, but it is not limited to this configuration, and may be configured in various shapes such as octahedron, hexahedron, tetrahedron, etc.

[0037] Furthermore, in the above embodiment, the first part 21 and the second part 22 are depicted as character faces D1 and D2, but the designs are not limited to these; for example, they could be designs of the costumes worn by the character.

[0038] Furthermore, in the above embodiment, the hole 23 is configured to protrude from the short side of the toy part 20, but it is not limited to this configuration, and may be a through hole provided at the corner of the toy part 20, for example.

[0039] Furthermore, although the above embodiment describes a way of playing in which the first part 21 and the second part 22 are connected by a strap 25, the invention is not limited to this, and for example, the first part 21 and the second part 22 may be used with the strap 25 attached separately.

[0040] Furthermore, although the above embodiment shows a single sub-body portion 30, it is not limited to this configuration and may include multiple sub-body portions 30 of different colors.
