Definitions

  • the invention relates to the soap industry.
  • It relates more particularly to the manufacture of soaps by a process of cold saponification, that is to say in which the synthesis of the soap is carried out at a temperature of the order of 40 to 50° - unlike the saponification at hot which implies much higher temperatures, around 120°.
  • the dough can take on texture more or less quickly depending on several parameters: the fragrance used, the temperature of the ingredients and the nature of the ingredients themselves, in particular the fatty substances chosen.
  • the object of the invention is, beyond these commonly available products, to be able to produce cold saponified soap bars comprising a inclusion, created in the mass and over the entire thickness of the bar of soap, of one or more predetermined geometric patterns of a color different from the color of the rest of the bar of soap.
  • the predetermined geometric pattern must in particular be able to be a rectangular or triangular, circular or fractional round pattern, in the shape of a scale, a diamond, a star, etc.
  • the FR 2 613 724 A1 proposes, after molding and hardening of soap bars of a first color, to cut out the center of these soap bars right through using a cookie cutter to form a hole there, then to cut in soap bars of a second color , also after molding and hardening, a piece of soap of the same size as the hole, to insert this piece of soap into the hole of the first soap, and finally to compress everything to homogenize the final product.
  • This technique although presented in an industrialized form, is not very profitable given the large quantities to be scrapped (cutting offcuts, not recoverable). It also does not allow a very wide variety of patterns, because of the mechanical stresses of resistance to cutting and to the insertion of the insert.
  • the WO 2006/063691 A1 describes a technique for molding a log-shaped "multi-phase" cylindrical soap block, with a core of a different color or composition than the rest of the log.
  • the technique uses an installation with two coaxial molds, with a central mold removed after pouring the core material to allow the pouring of the peripheral material, the latter being confined by the mold. external.
  • the two coaxial molds are moreover each provided with a hollow lining allowing the circulation of a fluid for cooling the cast materials, since these are hot saponifiable soaps.
  • the composite cylindrical log thus obtained is then detailed into individual round and flat bars, by cutting the log into successive slices along planes radial with respect to the axis of the cylindrical log.
  • the US 6,147,040A describes a comparable technique for a individually produced disc-shaped soap bar with a "rainbow" pattern of several different colors arranged concentrically.
  • the technique consists of molding a piece of soap in the shape of a flat disk in a mold of reduced diameter, then placing the piece of soap obtained after hardening in the center of a mold of larger diameter and pouring around it a mass of soap of a different color. , place the two-tone piece obtained in another mold of greater diameter, etc., and so on until the final product.
  • the US 2001/040312 A1 illustrates another technique for making multicolored soaps, by successive casting of masses of soap of different colors in the same mould. At each casting the mold is only partially filled, until the last casting which gives the soap its final shape.
  • the patterns produced are not, however, predefined geometric patterns, identical for all the bars of soap as in the case of the various processes described above, but more or less random patterns, in the form of marbling or colored spots.
  • the patterns that make it possible to achieve the known prior processes are all very limited in their variety, and in particular none makes it possible to produce bars of soap with materials of different color or composition which would simply be joined or juxtaposed, in a non-concentric manner. .
  • these horizontal and/or vertical cutouts can easily be made collectively by means of a lyre or racket of thin stretched steel wires capable of sinking into the mass of hardened soap.
  • Sub-claims 2 and 4-6 are directed to advantageous, subsidiary implementations of this method of manufacture.
  • FIG. 1 there is illustrated in perspective a tank for the manufacture of soaps according to the method of the invention, this tank comprising a bottom 10 and sides 12. These various elements are removable so as to allow easy demolding once the mass of soap solidified.
  • a tank of 28 ⁇ 28 ⁇ 30 cm making it possible to mold cubic bars of soap with a side of 28 cm, for a weight of the order of 20 kg.
  • vertical counterforms 14 are placed inside the mold, so as to leave empty spaces 16 between them. counterforms and the internal walls of the tank are preferably wrapped in a non-stick film 18 to allow easy demolding once the mass of liquid soap which will be poured into the mold has hardened.
  • Counterforms 14 are for example wooden or plastic counterforms. Characteristically of the invention, they have the shape of a right prism or a right cylinder (in the most general sense of the term, that is to say the volume described by a vertical line resting on a polygon or on a circular curve or not).
  • the counterforms are placed vertically in the mould, as can be seen in the Figure 1 , according to a regular layout (cf. plan view of the Figure 2 ) which will depend on the final pattern of the soap bars that one wishes to produce after the last step of the process (cf. Figure 6 ).
  • the profile, in plan, of these counterforms will be chosen according to the different soap patterns that one wishes to achieve, and examples of which are illustrated in Figure 9 .
  • the bottom 10 of the tank has markings forming benchmarks to facilitate the placement of the base of the counterforms according to their predetermined arrangement, for example in the form of a pattern placed under the bottom 10, the latter being made of a transparent material. (rigid plastic material such as PMMA or the like).
  • the next step of the process after having placed the counterforms, consists in preparing a first mass of cold-saponifiable soap of a first color A, and in pouring this first mass into the tank, in the empty spaces 16 remaining between the counterforms 14.
  • the result of this step after taking the mass of the soap of the first color A, is shown Figure 3 .
  • An important characteristic of the invention resides in the choice of a cold-saponifiable soap, with the characteristics set out above in the introduction. In fact, the caking of the soap occurs quickly, a few minutes after the mixing of the basic constituents.
  • the next step consists in preparing a second mass of cold-saponifiable soap of a second color B, different from color A, and in pouring this second mass into the tank in the empty spaces 20 provided by the removal of the counterforms.
  • the result of this step, after taking the mass of the soap of the second color B, is shown Figure 5 .
  • the respective horizontal and vertical cutouts are advantageously made collectively by means of a "lyre” or “racket” of thin stretched steel wires, capable of sinking into the hardened soap mass.
  • the counterforms 14 are replaced by blocks of soap molded to the desired shape, that is to say that the cylindrical vertical shapes or Prismatics are not made of wooden pieces, but of previously molded and/or cut blocks of soap.
  • the work is always carried out vertically, making it possible to produce a very large number of individual soap bars in a single process.
  • This method of manufacture differs in this respect from the current, artisanal processes, implementing horizontal flat trays in which the soap is poured into bars which are then detailed into individual soap bars.
  • This artisanal production, horizontally not only has the disadvantage of a low production rate, but in addition it does not make it possible to produce, as in the invention, bars of soap with inclusions in the mass, and over the entire thickness, of predetermined geometric patterns based on regions of different colors.
  • the Figure 9 illustrates various other examples of soap bars which it is possible to produce thanks to the teachings of the invention, with geometric patterns consisting of straight line segments and arcs of circles delimiting on the same soap bar the regions of different colors, with at least two colors A, B, possibly with a third color C.
