Definitions

  • the invention relates to a method for the production of a tablet of soap, said tablets of soap being made up of several layers of soap.
  • Tablets of soap which are used for cleansing, for example, the skin are generally known. In general, these tablets are made by pressing them in a mould. It is also known to cast the tablets of soap, in which case the soap must be liquid at a temperature which lies above the temperature at which said tablets of soap are to be used.
  • the aim of the invention is a method for the production of tablets of soap, in which a tablet of soap is made up of layers of soap, in which each layer can be of a different colour.
  • a mould comprising two or more parts which when combined form a mould with a filling aperture, said filling aperture being used to permit the filling of the remaining space in the mould with a soap which is liquid above a specific tempera­ture which is above 40 degrees Celsius, and which is solid below a temperature which lies below the above-mentioned specific temperature, while before the parts of the mould are combined one or more parts of the mould are filled with a soap at a temperature at which it is liquid, this soap layer is then cooled to a temperature which lies below the above-mentioned specific temperature, following which the mould is closed and the remaining space is filled up with a soap whose temperature lies above the melting point of said soap, each soap filling having a desired composition.
  • This process means that tablets of soap which are made up of several layers, and in which each layer can be of a dif­ferent desired colour, can be produced. This can greatly enhance the external appearance of the tablet of soap, most certainly if the tablet of soap is packed in a transparant piece of packaging material such as cellophane or trans­parant plastic.
  • a special effect is obtained if another possible process is used.
  • This other possible process is that after one or more layers are placed in one of the mould parts and cooled to a desired temperature, and before the mould parts are combin­ed, an object such as an illustration, free gift article, logo or the like, is placed on the last layer of soap for­med.
  • an object such as an illustration, free gift article, logo or the like, is placed on the last layer of soap for­med.
  • small objects can be placed in the soap during the production process.
  • This placing of small objects in the soap is all the more appealing since soaps which are virtually translucent or transparant can now be produced, with the result that these objects are visible from the outside of the soap, and they therefore differ from known tablets of soap which do not have the property of being transparant.
  • Fig. 1 shows a mould 1, comprising two parts 2 and 3, in which a tablet of soap 4 is moulded.
  • a layer of soap 5 was first poured into the part 2 of the mould 1 and, after this layer 5 had cooled to the extent that this soap layer 5 was no longer liquid, a new layer 6 of the same type of composi­tion as that of the first layer was poured in.
  • Such a first layer 5 will then not be able to heat up so far that it becomes completely liquid again, due to the fact that it takes quite a large amount of energy to convert a substance from the solid phase to the liquid phase; on the other hand, if the temperature difference between the two layers is not too great when the new layer is poured in, the two layers will adhere well, because the surface layer against which the new soap layer is poured will then melt slightly, especially since a soap of approximately the same composi­tion, in which, for example, only the colour is allways changed by adding a different dye, is used for all layers.
  • the last layer can be applied by closing the mould and filling up the mould through the filling aperture 7.
  • Fig. 2 shows a cross-section through a tablet of soap, in which the tablet of soap comprises a number of layers and contains an object 8. This object is inserted by placing it on a layer after the latter has cooled down sufficiently, and subsequently applying the other layers of soap.
  • This placing of logos or other small objects in a tablet of soap is now very attractive because soaps which are virtually transparent can now be made, which means that these objects are very easy to see from the outside.
