Abstract
ABSTRACT OF THE DISCLOSURE
A new soap bar is disclosed wherein a soap bar com-prises a soap bar body having a cavity stamped therein and a raised design or character imprinted in the bottom of the cav-ity. A smaller piece of soap of another colour is used to fill the cavity whereby the imprinted design or character become visible after the mass of soap above the imprint is washed away. This improvement allows the user to recognize the design or character during practically the entire useful life of the soap bar, even when the initial imprinted mark on the surface of the soap bar has already been washed off.

Description
Many soap bars with various appearances have been developed which, as a rule, depend upon various optical effects.
Those soap bars enjoy a great popularity with the consumer.
It has been known for quite some time that one can manufacture transparent soap bars. Marbled or striped soaps have also been on the market for a long time. A particulary esthetically appealing soap consists of two equally sized halves which are coloured differently. Manufacture of such soap is the subject matter of German Auslegeschrift No. 2,049,268.
Soaps are also known which contain a smaller piece of soap which is e~bedded in a base body of soap. The smaller piece usually has a colour which contrasts with the colour of the base body. Such soaps and their manufacture are described in German Offenlegungschriften No. 1,617,253 and 1,617,254.
A disadvantage of soaps in general and especially of the above described "inlaid soaps" is the fact that the addi-tional characters, emblems or other marks imprinted on the sur-face of such soaps, which serve for the differentiation and embellishment of the optical make-up of the soap, are quickly removed by wear. Thus, due to wear of a partially used soap bar, it is no longer possible for the user to determine which brand has been used.
BRIEF DESCRIPTION OF THE INVENTION
The present invention relates to a new type of soap bar and to a particularly suited process for manufacturing the soap bar.
It has been discovered that one can overcome the prior disadvantages in soaps whereby one may recognize such applied characters, emblems, marks, and so forth, during pract-~41~S6 1 ically the entire useful life of the soap bar and especially at the end of their usage.
This ob]ective is met by a soap bar which consists of a soap bar body of customary composition and of at least one smaller piece of soap embedded into its surface in a cavity having a relief design at the bottom of the cavity. The cavity then serves to take up the smaller embedded piece of soap which itself may have imprinted on its surface a similar relief design in the form of a character, emblem, heraldic figure or other mark.
As a result of the construction of the inventive soap, it is possible to maintain the visibility of the imprinted mark throughout the usage period of the soap bar even when the ini-tial imprinted mark on the surface of the soap (e.g., on the smaller inset piece of soap~ has already been washed off. It is also possible to make this mark visible again in ~he almost washed away soap bar.
The subject matter of the present invention further comprises a process for manufacturing a soap bar according to ~ the invention. The process comprises manufacturing a soap bar in a known manner, stamping out a cavity therein and providing at the bottom of that cavity, an imprint, preferably having a raised design. Subsequently, a smaller, preshaped piece of soap is inserted in the cavity of the soap body provided for the purpose.
The insertion of the smaller piece of soap into the cavity of the base soap body can be optimally achieved if the smaller piece of soap to be imbedded as well as the cavity of the base soap body are shaped as a cone or section of a cone.
To this end, in one of its aspects, the inver,tion 1 provides an improved soap bar consisting of a soap bar body and at leasc one smaller piece of soap embedded in a corrspond-ing cavity in at least one surface of the body, said improvement comprising providing a relief design at the bottom of the soap bar body in which the small piece is embedded.
In another of its aspects, the invention provides a process for manufacturing a soap bar which consists of a soap bar body and at least one smaller piece of soap embedded in a corresponding cavity in at least one surface of the body, and wherein a relief design is provided at the bottom of the soap bar body in which the smaller piece is embedded, the process comprising forming a soap bar, stamping at least one cavity into the bar, imprinting a relief design into the bottom of the cavity, and filling the cavity with soap.
DETAILED DESCRIPTION
The figure illustrates a soap bar structured according to the present invention.
Cavity 2 is stamped into the surface of soap bar body 1, and a smaller piece of soap 3 is embedded therein. The smaller soap piece 3 has a colour different from that of soap bar body 1. The embedded piece of soap 3 is provided with a raised character 4 on its surface. At the bottom of cavity 2, there is likewise, a similar raised character 5 which is imprinted prior to imbedding the smaller piece of soap therein.
Raised character 5 becomes visible to the user after the above situated soap mass has been washed away.
The soap masses for the soap bar body and for the smaller piece of soap to be imbedded therein may be manufactured separately such as by extrusion with extruders which are arranged in parallel next to one another. Both of the parallel soap 1 ropes coming out of the extruders are cut into unfinished pieces of suitable size. Then the cavity is stamped into the soap body corresponding in size to the formed smaller pieces of soap. The bottom of the cavity is then imprinted with a relief design which may be, for example, a raised character. The formed smaller pieces of soap are inserted into the so~p body cavity. Thc soap bar thus manufactured is stamped and if need be, is provided with an additional imprint.
The soap bodies can have any suitable shape ~e.g.
round or oval) and the embedded smaller piece of soap can like-wise have any desired shape.
The chemical composition of the inventive soap barsis in accordance with that customarily used for soap ~ars. As used herein, the term "soap" is understood to include alkali salts of higher fatty acids as well as the so-called surface active soaps which contain the usual ad~itives. In this regard, reference is made to the data in Ullmann's Enzyklopadie der technischen Chemie, 3rd editions, volume 18, pages 355-395 ~1967, Urban & Schwarzenberg, Munich, Berlin, Vienna~ and to the monograph of D. Osteroth, "Kosmeticum Feinseife" (1972, Huthig-Verlag, HeidelbergJ.
It has been found especially useful to shape thebottom of the embedded smaller piece of soap as a cavity corre-sponding to the raised relief design of the cavity bottom of the soap bar, i.e. as "negative mold" of said raised relief. This improves the firmness of both pieces and prevents damage of said raised relief design during stamping of the finished soap bar.
Although the disclosure describes and illustrates a preferredembodiment of the invention, it is to be understood the invention is notrestricted to this particular embodiment.
Those soap bars enjoy a great popularity with the consumer.
