Abstract

[Problem] To provide a solid bath additive that is highly appealing. [Solution] The solid bath additive 1 comprises a water-soluble main body 10 and a water-insoluble auxiliary body 20, wherein the auxiliary body 20 includes either a first type of auxiliary body that floats in water or a second type of auxiliary body that sinks in water, selected as the first auxiliary body 21, and the main body 10 is configured to enclose the first auxiliary body 21 before dissolution, and to make the first auxiliary body 21 visible after dissolution. Because it is uncertain whether the water-insoluble auxiliary body enclosed in the solid bath additive 1 will sink or float in the bathwater, for example, it is possible to create an effect where the toy form after the main body 10 of the solid bath additive 1 has dissolved is unpredictable.

Conventionally, as a solid bath additive, for example, Patent Document 1 discloses a water-soluble, hollow solid bath additive and a hollow, mascot-shaped component that can be disassembled and assembled, placed inside the solid bath additive. Utility Model Registration No. 3240450 This is a perspective view of a solid bath additive according to the first embodiment of the present invention.Figure 1 is a schematic cross-sectional view showing an example of the inside of a solid bath additive.Figure 1 is an explanatory diagram showing an example of what happens when a solid bath additive is added to bathwater.This is an explanatory diagram showing a state in which the first sub-body is covered by the main body which is in the process of dissolving, and the second sub-body is in the process of floating to the surface.This is an explanatory diagram showing an example of the state of the auxiliary body after the main body has dissolved.This is a perspective view showing the structure of the auxiliary body.This is a perspective view showing the main parts of the auxiliary body disassembled.This is a front view showing the assembled display state of the sub-body in the first embodiment.This is a perspective view of the initial state of the product as it is placed in the bathwater in the second embodiment.This is a cross-sectional view showing the interior of the main body in the second embodiment.This is a schematic diagram showing the state after the main body has dissolved in the second embodiment.This is a front view showing the assembled display state of the sub-body in the second embodiment. (First aspect) The following describes a first embodiment of a solid bath additive representing one aspect of the present invention, with reference to the figures. Figure 1 is a perspective view of solid bath additive 1. Figure 2 is a schematic cross-sectional view showing an example of the inside of solid bath additive 1. As shown in Figures 1 and 2, the solid bath additive 1 comprises a water-soluble, spherical main body 10 and a water-insoluble auxiliary body 20 inside the main body 10. Until dissolved by water or hot water, the solid bath additive 1 is covered by the main body 10, concealing the auxiliary body 20. The configuration of the auxiliary body 20 can be either, as shown in Figure 2, where multiple auxiliary body 20s are embedded within the main body 10, or where a housing space is formed inside the main body 10, and the auxiliary body 20s are housed within this space. The spherical main body 10 has an opaque, appropriately colored surface, and its outer surface 10s has, for example, small irregularities that create a rough texture. This rough texture increases the surface area, making it easier to dissolve, and the main body 10 is made of a water-soluble material whose color dissolves into surrounding water or hot water. A parting line 10j is formed around the outer circumference of the outer surface 10s. This is the configuration when the main body 10 is formed by injection molding, for example. However, in the case of molding two hemispheres with internal storage spaces joined together, this parting line 10j becomes the connecting portion of the hemispheres. The sub-body portion 20 includes, for example, a first sub-body portion 21 modeled after a character and a second sub-body portion 22 shaped like a barrel. The first sub-body portion 21 is composed of either a first type of sub-body portion that floats on water or a second type of sub-body portion that sinks on water. In this embodiment, the first sub-body portion 21 is made of polyvinyl chloride, a material that sinks on water. On the other hand, the second sub-body portion 22 is always designed to float on water and is made of the same material as the first type of sub-body portion, for example, thermoplastic rubber. Furthermore, while the first sub-body portion 21 is configured as a sub-body portion of type 2 that sinks in water in this embodiment, it can also be configured as a sub-body portion of ty
