Abstract
Abstract A process for the preparation of soap articles containing dried shapes also formed of soap, comprises the steps of placing on the bottom of a cylindrical frame a supporting base transparent soap which has been cooled to solidification but has not been dried as yet, said base having a height lower than that of said frame; fixedly placing a dried shape(s) of colored soap on said supporting base; pouring in said frame a dough of transparent soap which may or may not be colored, and put into a molten state by heating, followed by cooling thereof to solidification; and removing the thus solidified transparent soap with said supporting base from said frame, followed by drying thereof. Instead of using the base, use may be made of one or plural needles.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
180 words
A process for the preparation of a soap article containing an embedded dried shape also formed of soap, comprising the steps of forming a desired shape from a colored soap made from a first soap composition containing water, and drying said shape, providing a second soap composition which is a transparent soap composition containing water, placing on the bottom of frame means a supporting layer of said second soap composition which has been cooled to solidification but not dried, said transparent soap supporting layer having a height lower than that of said frame means; placing said desired dried shape of colored soap on said transparent soap supporting layer; and fixing said dried shape on said supporting soap layer, pouring into said frame means a molten dough of said second transparent soap composition and cooling said molten dough to solidification; thereby fusing said dough with said supporting layer, there being complete integration of said layer and said supporting molten dough to prevent separation; removing the thus solidified transparent soap including said supporting layer from said frame means, and drying said soap.
Claim 2
Dependent Claim
180 words
A process for the preparation of a soap article containing an embedded dried shape also formed of soap, comprising the steps of forming a desired shape from a colored soap made from a first soap composition containing water, and drying said shape, providing a second soap composition which is a transparent soap composition containing water, placing on the bottom of frame means a supporting layer of said second soap composition which has been cooled to solidification but not dried, said transparent soap supporting layer having a height lower than that of said frame means; placing said desired dried shape of colored soap on said transparent soap supporting layer; and fixing said dried shape on said supporting soap layer, pouring into said frame means a molten dough of said second transparent soap composition and cooling said molten dough to solidification; thereby fusing said dough with said supporting layer, there being complete integration of said layer and said supporting molten dough to prevent separation; removing the thus solidified transparent soap including said supporting layer from said frame means, and drying said soap.
Claim 3
Dependent Claim
19 words
The process according to claim 1, further comprising said first and second soap base being essentially the same composition.
Claim 4
Dependent Claim
35 words
The process according to claim 1, further comprising forming said desired shape from a colored soap made from a first soap base and drying said shape to about 50 to 70% of its original weight.
Claim 5
Dependent Claim
145 words
A process for the preparation of a soap article containing an embedded dried shape also formed of soap, comprising the steps of: inserting one or more needle members in a frame means through a bottom plate closely fitted into the bottom of said frame means; forming a desired shape from a colored soap made from a first soap composition containing water, and drying said desired shape, securing said shape onto said needle member pouring into said frame means a molten dough of a second soap composition which is transparent and contains water, cooling said molten dough to solidification sufficient to prevent movement of said desired shape; and separating the thus solidified transparent soap from the said frame and said needle members, closing the hole remaining on the underside of the soap by removal of the needle by applying heat, followed by drying of said soap.
Claim 6
Dependent Claim
145 words
A process for the preparation of a soap article containing an embedded dried shape also formed of soap, comprising the steps of: inserting one or more needle members in a frame means through a bottom plate closely fitted into the bottom of said frame means; forming a desired shape from a colored soap made from a first soap composition containing water, and drying said desired shape, securing said shape onto said needle member pouring into said frame means a molten dough of a second soap composition which is transparent and contains water, cooling said molten dough to solidification sufficient to prevent movement of said desired shape; and separating the thus solidified transparent soap from the said frame and said needle members, closing the hole remaining on the underside of the soap by removal of the needle by applying heat, followed by drying of said soap.
Claim 7
Dependent Claim
50 words
The process as recited in claim 1 or 4, in which the coloring material for said embedded dried shape of colored soap, is selected from finely divided, colored synthetic resin; finely divided, colored silica gel; microcapsules with filled-in coloring matters, and a mixture of two or more of these substances.
