[0009] Hereinafter, an embodiment of a solid bath additive representing one aspect of the present invention will be described with reference to the drawings. Fig. 1 is a perspective view of a solid bath additive 1. Fig. 2 is a schematic cross-sectional view of the solid bath additive 1 shown in Fig. 1.
[0010] As shown in Figure 1, the solid bath additive 1 comprises a substantially spherical, water-soluble main body 10A (10) and a doll body 20A (20) contained within the main body 10A. The doll body 20A, which resembles a specific first character, is held in the solid, water-soluble main body 10A, so that when the solid body 10A is placed in a solution, such as bathwater 50 (see Figure 3), the main body 10A dissolves, revealing the doll body 20A. There are no particular restrictions on the manufacturing form of the main body 10A; for example, the main body 10A can be formed by combining halves 11 and 12 having a specific outer surface pattern 10m on the outer surface and an internal space.
[0011] The doll body 20A is made of a relatively flexible, water-insoluble material such as synthetic resin or rubber, and is designed to float on water. However, the main body 10A is made of a material that does not float on water. Therefore, the solid bath additive 1 can be designed to float on water or sink on water, depending on the weight ratio of the main body 10A to the total weight.
[0012] As shown in FIG. 2, the main body 10A of the solid bath additive 1 forms the surface 10s, forming an internal storage space SP. A doll body 20A and a tablet-shaped secondary body 30A are provided within the storage space SP. This configuration allows the solid bath additive 1 to appear after being dropped into bathwater 50 and dissolving. The secondary body 30A contains a pigment that dissolves upon contact with the bathwater 50 and produces a predetermined color, such as white. Several types of doll bodies 20A are available for inclusion in the main body 10A, and the selection is determined based on the main body 10, as described below. The exterior color of the main body 10A is a warm-looking color, such as orange. In addition to the coloring matter, the main body 10A also contains, for example, a citrus-based fragrance component and a carbonated foaming component.
[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. The solid bath additive 1 is configured so that the main body 10A floats on water. In this case, when the solid bath additive 1 is poured into bathwater 50, a first color 51, which is the orange appearance color of the main body 10A, is formed, as shown in FIG. 3. Then, over time, for example, the first color 51 area of the main body 10A expands, and the appearance color of the bathwater 50 becomes a transparent light orange. Then, as the color dissolves, the main body 10A melts and shrinks. Furthermore, as the main body 10A dissolves, bubbles 58 appear due to the foaming component contained therein.
[0014] FIG. 4 is an explanatory diagram showing the state of the bath water 50 when the main body 10 has almost dissolved. As the solid bath additive 1 begins to dissolve (as shown in FIG. 3), the doll body 20A floats on the surface of the water until the main body 10 has almost completely dissolved, as shown in FIG. 4. At this time, a region of a second color 52, for example, white, different from the original orange first color 51, appears around or near the doll body 20A within the first color 51. This second color 52 is the color of the dissolved secondary body 30A.
[0015] The secondary body 30A is constructed to be heavy enough to sink in water, and is therefore located on the bottom of the bathtub 60 directly below or near the floating doll body 20A. Therefore, when the second color 52 begins to appear, the color near the doll body 20A begins to change, as shown in Figure 4. Eventually, the entire bathwater 50 changes to a color that is a mixture of the second color 52 and the first color 51. In this case, a warm skin color, which is a composite color of orange and white, can be achieved.
[0016] The first color 51 and second color 52 of the main body 10A and the secondary body 30A are colors that match the character's exterior color or a color that corresponds to a part of the exterior color, or are colors that match or are similar to the character's image color. Apart from this change in appearance, the bathing effect also includes ingredients that have a heat-retaining effect, keeping the body warm even after getting out of the tub. These heat-retaining ingredients can be contained in either or both of the main body 10A and the secondary body 30A.
[0017] FIG. 5 is a cross-sectional view showing another example of the solid bath additive 1. As shown in FIG. In the case of the solid bath additive 1 shown in FIG. 5, the doll body 20B contained in the storage space SP is modeled after a second character different from that shown in FIG. 2. The doll body 20B shown here is modeled after an animal that lives in cold climates, such as a penguin. The main body 10B is colored, for example, light blue. The secondary body 30B is configured to be able to develop a color corresponding to the character of the doll body 20B. The solid bath additive 1 is configured to have a weight that allows it to sink in water. Therefore, in this case, when the solid bath additive 1 is poured into the bath water 50, it sinks to the bottom of the bathtub 60.
[0018] FIG. 7 is a perspective view showing the state of the doll body 20B and bath water in a state in which the main body 10B shown in FIG. 6 has dissolved. When the solid bath additive 1 is poured into the bath water 50, it sinks to the bottom of the bathtub 60. Then, the third color 53 dissolves into the bath water 50, turning it, for example, a transparent light blue. After a certain amount of time has passed and the dissolution of the main body 10B is almost complete, the doll body 20B rises to the surface as shown in Figure 6. This allows the identity of the character to be revealed for the first time.
[0019] Around the time that the main body 10B finishes dissolving, the secondary body 30B comes into contact with the bathwater 50 and begins to dissolve. As the secondary body 30B dissolves, a fourth color 54, a darker blue than the light blue, appears against the third color 53, as shown in FIG. 6 . The secondary body 30B contains not only the pigment of the third color 53 but also other ingredients, such as menthol. Furthermore, a fragrance component, such as a soda scent, can be added. The bathing effect, in line with the appearance of the third and fourth colors 53 and 54, can be a refreshing sensation upon emerging from the bathwater 50. As the main body 10B dissolves, the bathwater 50 is colored the third color 53, a clear, cool-looking light blue.
[0020] Furthermore, since the secondary body 30B is constructed with a weight that allows it to sink in water, it sinks to the bottom of the bathtub 60 directly below or near the floating doll body 20B. As a result, as in the case shown in FIG. 4, the fourth color 54 begins to change color near the doll body 20B, as shown in the figure. Furthermore, in the final stage where most of the secondary body 30B has dissolved, the remains 30b of the secondary body 30B float up, as shown in the figure. This state can be used to represent, for example, a penguin and ice, further enhancing the feeling of coolness.
[0021] FIG. 7 is a cross-sectional view showing another example of the solid bath additive 1. As shown in FIG. In the configuration shown in Fig. 7, the doll body 20C accommodated in the accommodation space SP of the main body 10C is modeled after a third character different from those shown in Figs. 2 and 5, such as a four-legged animal with a long tail. A third sub-body 30C is also provided within the accommodation space SP. The doll body 20C is configured in warm colors such as brown or red, for example, to give the character a warm impression.
[0022] In this embodiment, the main body 10C has a two-layer structure consisting of an inner layer 10i and an outer layer 10u. The outer layer 10u of the main body 10C is, for example, a pink fourth color 54, and the inner layer 10i is, for example, an orange fifth color 55. The secondary body 30C is, for example, a red sixth color 56. The secondary body 30C further contains, in addition to the sixth color 56, a component that provides a sensation of warmth to the body.
[0023] FIG. 8 is a perspective view showing the doll body 20C and bath water in a state in which the main body 10C shown in FIG. 7 has dissolved. When the main body 10C of the solid bath additive 1 is dropped into the bathwater, the pink of the fifth color 55 is dissolved, followed by the orange of the sixth color 56. Then, a mixture of these colors is formed. After that, the red of the seventh color 57 is dissolved by the secondary body 30C. All of these colors are warm colors that correspond to the color of the doll body 20C. Furthermore, the components that dissolve from the secondary body 30C, which will be described later, provide a physical sensation of warmth.
[0024] In this embodiment, components that can be contained in the main body 10 and the secondary body 30 include components that change the color of the bathwater 50, components that release fragrances, and components that directly stimulate the skin. Examples of colors include gray, red, blue, green, yellow, dark blue, orange, purple, brown, light blue, dark red, green, light brown, light purple, black, and pink. Examples of fragrances include milk, ocean, forest, citrus, soda, orange, grape, earth, soap, lavender, cypress, rock, chamomile, peach, and carbonated drink. Examples of direct sensations on the skin include moisturizing, warming, refreshing, smooth skin, sweating, and blood circulation promotion, as well as skin cleansing and softening the water by effervescence.
[0025] As described above, in the solid bath additive 1 of this embodiment, for example, the doll bodies 20 (20A, 20B, 20C) that resemble specific characters are enclosed in the main body 10, so that they are invisible from the outside until the main body 10 dissolves. The doll bodies 20 can then be seen for the first time when the solid bath additive 1 is poured into the bathtub 60 and the main body 10 dissolves. The doll bodies 20 that appear also create a sense of excitement as to what will appear.
[0026] Furthermore, in the solid bath additive 1 of this embodiment, a doll body 20 associated with the state of the dissolved liquid is selected and displayed, thereby achieving a synergistic effect between the change in appearance of the doll body 20 and the liquid. Furthermore, in addition to the change in appearance of the bathwater 50, the sensory changes felt on the skin can be made to correspond to the sensations of the doll body 20 or the sensations that correspond to the appearance, such as color.
[0027] In the solid bath additive 1 of this embodiment, when the main body 10 begins to melt, the appearance of the bathwater, such as its color and transparency, changes. As this happens, you can enjoy imagining what kind of doll body 20 corresponds to the character's image, including the high temperature and refreshing sensation felt on the skin.
[0028] Furthermore, the solid bath additive 1 of this embodiment contains ingredients that provide bathing, heat retention, cleansing, and moisturizing effects, allowing for a fun presentation of the association between the effects and the character of the doll body 20.
[0029] In the solid bath additive 1 of this embodiment, the doll body 20 is covered with the foamed main body 10, so that the player can play by searching for the doll body 20 among the foam.
[0030] In the solid bath additive 1 of this embodiment, a secondary body 30 that dissolves in liquid is provided within the main body 10, so that the secondary body 30 can produce a color that is different from the apparent color when the main body 10 dissolves.
[0031] In the solid bath additive 1 of this embodiment, the secondary body 30 is provided in the main body 10 adjacent to the doll body 20, so that the color of the bath water 50 can be changed with a time lag.
[0032] 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 secondary body 30 is one, but this is not limited to this configuration and may be two or more. Furthermore, in the above embodiment, the secondary body 30 is configured to sink in water, but this is not limited to this and it may be configured to float on water.
[0033] Furthermore, in the above embodiment, the shape of the doll body 20 and the description of the color that melts from the main body 10 are not limited to the above-described contents.
