[0009] Hereinafter, an embodiment of a solid bath additive representing one aspect of the present invention will be described with reference to the drawings.
[0010] (First aspect) Fig. 1 is a perspective view of a first type of solid bath additive 1. Fig. 2 is a schematic cross-sectional view of the solid bath additive 1 shown in Fig. 1. As shown in Fig. 1, the solid bath additive 1 comprises a water-soluble main body 10 having a spherical surface 10s, and a toy doll body 20 contained in the internal space SP of the main body 10. The doll body 20, which resembles a specific character, is held in the solid main body 10, which dissolves in water, so that when the solid bath additive 10 is placed in a liquid, such as bathwater 50 (see Fig. 3), the main body 10 dissolves and the doll body 20 appears.
[0011] The doll body 20 is made of a relatively flexible, water-insoluble material such as synthetic resin or rubber, and is designed to float in water. However, the main body 10 is made of a material that does not float in water, and the solid bath additive 1 is designed to sink in water.
[0012] As shown in Figure 2, for example, the solid bath additive 1 has a two-layer structure consisting of an outer layer 11 on the surface 10s side and an inner layer 12 inside the outer layer 11. The outer layer 11 contains a pigment that produces a first color when it dissolves, and the inner layer 12 contains another pigment that produces a color different from the first color. Therefore, when the solid bath additive 1 is poured into the bathwater 50, the color it produces when it first starts to dissolve in the bathwater 50 is different from the color it produces thereafter, as will be described later.
[0013] FIG. 3 is an explanatory diagram showing the state in which the solid bath additive 1 is placed in bathwater 50. As shown in FIG. As described above, the solid bath additive 1 is constructed so that the main body 10 sinks in water. When the solid bath additive 1 is dropped into bathwater 50, it sinks to the bottom 61 of the bathtub together with the floating doll body 20, as shown in Figure 3. In this sunk state, the main body 10 dissolves from its surface 10s.
[0014] The first color component emerging from the surface 10s of the main body 10 rises together with the air bubbles 18 and rises above the bathwater surface 50a. Then, in the first stage, the bathwater surface 50a changes to the first color. After the outer layer 11 dissolves, in the second stage, the inner layer 12 dissolves, revealing the second color, further changing the color of the bathwater 50.
[0015] FIG. 4 is an explanatory diagram showing the state in which the doll body 20 has risen to the surface 50a of the water. In the first stage, when the solid bath additive 1 begins to dissolve, it appears as a first color C1. Then, before the doll body 20 floats up, it changes to a second color C2 in the second stage. After the second color C2 appears, the doll body 20 floats up in the final stage, as shown in Figure 4. At this time, the doll body 20 floats up together with the remaining portion 12a of the inner layer 12. Therefore, as shown in the figure, the remaining portion 12a is floating around the doll body 20, and the second color C2 continues to dissolve from this remaining portion 12a.
[0016] In this way, from a state where it is unclear which character it is (the state before the doll body 20 emerges), the appearance (emergence) of the doll body 20 is produced in a two-color state in which the first color C1 and the second color C2 are not completely mixed, as shown, around the time the doll body 20 emerges.
[0017] In the first embodiment, the main body 10 has an internal space SP, but the present invention is not limited to this, and the internal space SP may also be filled with the inner layer 12 (i.e., the inner layer 12 is formed in close contact with the periphery of the doll body 20). In this embodiment, the time from when the main body 10 starts to dissolve until the toy 20 becomes visible can be extended, and the risk of damage to the main body 10 before dissolution can be reduced.
[0018] (Second aspect) FIG. 5 is a schematic cross-sectional view of a second type of solid bath additive 1 containing a doll body 20 modeled after another character. In the second type of solid bath additive 1 shown in FIG. 5, the contained doll body 20 is different from that shown in FIG. 2. The main body 10 also has a single-layer structure rather than a two-layer structure. Furthermore, the components contained in the main body 10 include a pigment component of the third color C3 and a foaming component. For example, the main body 10 also contains a foaming component such as carbonic acid that generates bubbles when it dissolves, and these components include, for example, at least sodium carbonate, citric acid, and sodium sulfate.
[0019] FIG. 6 is an explanatory diagram showing the state in which the doll body 20 has risen to the surface 50a of the water. In the case of the solid bath additive 1 of this embodiment, once the main body 10 begins to dissolve and a predetermined time has passed, the bathwater 50 is dyed a third color C3 and a certain amount of bubbles 10b are formed. However, unless any particular operation is performed to form a large amount of bubbles 10b, the doll body 20 will rise to the surface and become visible, as shown in Figure 6. In this case, the doll body 20 can be hidden in the bubbles by adding hot water through the faucet 80 or by manually vibrating (stirring) the water surface 50a to mix air into it.
[0020] Furthermore, if an operation such as mixing air into the water surface 50a is performed before the doll body 20 rises above the water surface 50a, the water surface 50a will be covered with bubbles 10b, and the doll body 20 will not be visible even if it rises. As a result, it is possible to create a state in which it is completely unclear for a certain period of time when the doll body 20 rose to the surface or what kind of character it is.
[0021] FIG. 7 is an explanatory diagram showing an example of how to play with the solid bath additive 1 in a foamed state. The bathwater 50 is colored the third color C3 by the dissolved color components, and the bubbles 10b are white, allowing you to enjoy the color contrast between the color of the bathwater 50 and the white color of the bubbles 10b.
[0022] As mentioned above, if a large number of bubbles 10b are formed before the doll body 20 rises to the surface, the floated doll body 20 will be covered with bubbles 10b and will not be visible. In this state, a player can have fun searching for the doll body 20 by feeling around from the bottom of the bath water 50, or, as shown in Figure 7, by pushing aside the bubbles 10b with a hand 70 from above the bubbles 10b to find the doll body 20.
[0023] (Third aspect) FIG. 8 is a schematic cross-sectional view of a third type of solid bath additive 1 containing a doll body 20 modeled after another character. In the third type of solid bath additive 1 shown in Fig. 8, the internal space SP contains a doll body 20 as well as a sub-body 30. In this embodiment, as in the first embodiment, the main body 10 has a two-layer structure consisting of an outer layer 11 and an inner layer 12. The outer layer 11 contains a pigment component of a fourth color C4, and the inner layer 12 contains a pigment component of a fifth color C5.
[0024] A large number of secondary bodies 30 are made of a mineral such as mica and are provided around the doll body 20 in the internal space SP. The secondary bodies 30 are formed, for example, in a star shape and are large enough to decorate the periphery of the doll body 20.
[0025] FIG. 9 is an explanatory diagram showing the state in which the doll body 20 has risen to the surface 50a of the water. When the main body 10 of this embodiment is placed in the bathwater 50, it sinks into the bathwater 50, as shown in FIG. 3 . Then, as the outer layer 11 and inner layer 12 of the main body 10 dissolve sequentially, the bathwater 50 is colored with the fourth color C4 and the fifth color C5. Then, as shown in FIG. 9 , the doll body 20 and the secondary body 30 rise to the surface. In this state, when the doll body 20 and the secondary body 30 first rise to the surface, the fourth color C4 and the fifth color C5 have not yet completely mixed on the bathwater surface 50a. As shown in FIG. 9 , the surroundings of the doll body 20 are decorated by the sparkling reflections of these two colors and the secondary body 30 due to the fluctuations of the bathwater surface 50a. Furthermore, because the secondary body 30 is made of mica, it dissolves into the bathwater 50 after a predetermined time has passed.
[0026] As described above, in the solid bath additive 1 of the above embodiment, as the main body 10 dissolves, it can undergo a first type of change in which the color of the bath water 50 (liquid) changes between a first color and a second color, a second type of change in which it foams when stirred or otherwise manipulated, and a third type of change in which the secondary body 30 (mineral fragment) floats in the bath water 50, thereby enabling a variety of presentations when the doll body 20 emerges from within the main body 10.
[0027] Furthermore, after the main body 10 is placed in the bath water 50, as the main body 10 becomes smaller and the appearance of the doll body 20 approaches (time passes), the color of the bath water 50 can change, or bubbles can be generated.
[0028] Furthermore, in the solid bath additive 1 of the above embodiment, the main body 10 is spherical, so that it can be rolled around and played with.
[0029] In addition, in the second type of solid bath additive 1, the foaming component of the main body 10 can be made to generate bubbles by stirring or vibrating during or after dissolution, so that it is possible to provide a more secrecy-enhanced way of enjoying the product by burying the doll body 20 floating in the bathwater 50 in bubbles and imagining what the character is.
[0030] Furthermore, in the third type of solid bath additive 1, dissolution of the main body 10 causes the secondary body 30, made of a mineral capable of floating in the bathwater 50, to appear, allowing the bathwater 50 to be decorated with a sparkling glow, creating the appearance of a doll body 20 floating on the bathwater surface 50a. Furthermore, because the secondary body 30 is made of a mineral capable of dissolving in water, it is easy to use and requires no cleanup.
[0031] Although the 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 has a spherical body 10, but this configuration is not limited to this, and various shapes such as an octahedron, a hexahedron, or a tetrahedron may also be used.
[0032] Furthermore, in the above embodiment, the second type (foam-generating type) and the third type (mica-containing type) of solid bath additive 1 are described as having separate configurations, but this is not limited to this, and the solid bath additive 1 may have both the second and third types of configurations at the same time.
[0033] In the above embodiment, the solid bath additive 1 is configured to sink in water, but this is not limiting and it may be configured to float on water.
