JPH11116998A - Soap having core therein - Google Patents

Abstract

PROBLEM TO BE SOLVED: To obtain a soap having a core therein which can prevent a soap from being disposed of without completely consuming the soap in such a stage that the soap has been brought to a thin plate form which is poor in foamability, and, in addition, is improved in effective utilization of soap materials and convenience involved in use of soaps by adopting a structure comprising a core material covered with a soap. SOLUTION: This soap has such a structure that a core material is embedded in a solid soap and, if necessary, a part of the core material is extended outside the soap. By virute of this structure, the soap can be used up until the core material is exposed. Therefore, the soap material can be saved. The core material can be recovered and again covered with a soap, realizing recycling of the core material. When a material having a lower specific gravity than the solid soap is used as the core material, the soap can be floated on water. This can solve such a problem that the soap is lost in a bathtub. When the core is made of a material having properties like a sponge, the core can be utilized as a washing tool. Further, a part of the core material may be extended outside the solid soap, and the extended portion may have a structure having a shape of a ship, a small bird, a flower or the like. This structure can also be used as a toy in bathtubs.

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an effective use of soap resources and an improvement in the convenience of soap. [0002] Regarding the solid soap technology, there has not been a technical idea of adding a core material to the soap to effectively use the soap resources and to improve the convenience thereof. [0003] As the solid soap is used, the soap melts from the surface, and the surface area is reduced to form a thin plate.
Since the foaming deteriorates and the shape easily collapses, the soap is often discarded at this stage without being completely consumed, and there has been a problem in terms of effective use of resources. The present invention has been made to solve this problem. [0004] The soap material has a structure in which the core (1) is covered with a soap (2) around the core material (1), thereby achieving an effective use of the soap material and an improvement in convenience in using the soap. . In the conventional bar soap, when the soap is used, the soap starts to melt from the surface, and when the soap becomes a thin plate, the soap melts out and foams are deteriorated, and the shape is liable to collapse. Often discarded. In the solid soap having a core therein according to the present invention, the soap is completely consumed up to the above stage while keeping its shape, and only the core remains. The core material can be selected according to expected convenience, but if a material such as sponge or pumice is used, the core material can be used as a cleaning tool. Further, the core material can be collected and processed again into soap, so that the soap resources can be effectively used. As a side effect, by selecting a material having a lower specific gravity than the soap as the core material, the solid soap comes to float in water. The inconvenience of losing soap in the bathtub is eliminated. By adopting a structure in which a part of the core material is pulled out to the outside of the solid soap, for example, the drawer portion is hook-shaped and the soap is hung using this, or the drawer portion is, for example, a toy ship, a water bird, The flower-like structure can provide soap with new and additional conveniences such as bathtub toys and bathtub decorations. An embodiment of the present invention will be described below. (A) The core material was covered with soap in a desired shape by a method such as extrusion molding, injection molding, or melt immersion. (B) The shape of the core material (1) is shown in FIG.
As shown in (1), the core material has a so-called disc shape in which the periphery is thinner than the center portion. (C) As shown in FIG. 3A, a part of the core material is drawn out of the soap to the outside. (D) By using a material having a lower specific gravity than the soap, such as cork, plastic foam, pumice, etc., as the core material, the soap could be floated in water. (E) In the example of FIG. 3 in which a part of the core material is pulled out of the soap, when the water is to be floated on water, the soap part may be floated on the water surface with the outer core material facing down, or the soap part may be facing downward. It was possible to float on the water surface with the outer core material facing up. By embedding a core material inside a solid soap or by taking out a part of the core material to the outside of the soap, the following new effects are obtained in the soap. (A) Since the soap can be used up until the core material is exposed, the soap material is saved. (B) The core material is recovered, and the soap can be coated thereon again to enable recycling. (C) Soap can be floated on water. (D) A part of the core material pulled out can be used for hooks, handles, toys, decorations and the like.
