Definitions

  • the present invention relates to a method for producing detergent or cleaning agent portions, which have an envelope made of water-soluble materials, which closely surrounds the compositions contained in the portion.
  • Portioned detergents and cleaning agents are widely described in the prior art and are becoming increasingly popular with consumers because of the simple dosage.
  • the portioning can be achieved, for example, by converting it into a compact form or by separate packaging.
  • tableting has an outstanding role; in the latter case, in the area of detergents or cleaning agents, mainly portions are used which are surrounded by packaging made of water-soluble materials.
  • these portions have the disadvantage of not having the high degree of compactness that tablets have.
  • the filling of tubular bags leads on the one hand to a low degree of compression, and on the other hand to a technically determined empty volume, so that a quantity of a detergent or cleaning agent measured for a washing or cleaning cycle takes up a larger space than a corresponding quantity in tableted form.
  • the empty volume means that filled bags are unstable against mechanical influences and can burst.
  • washing or cleaning agent containers on the market are that they still have to be provided with an outer packaging which protects the ingredients from environmental influences (in particular moisture).
  • These "flow packs" made of water-insoluble materials must be removed by the consumer before metering, which can be annoying to the consumer and cause waste.
  • Approaches to solving this problem are coating the molded body with water-soluble polymers or using water-soluble packaging.
  • a coating provides visually appealing tablets with a smooth, glossy surface and advantageous haptic properties.
  • the coating of tablets is technically complex and expensive.
  • the use of water-soluble packaging is described in the prior art in the form of bags made of water-soluble film.
  • these tablets have aesthetic disadvantages compared to conventional tablets. Consumer acceptance too is low in this form of offer, since the outer packaging suggests to the consumer that it has to be removed - a real advantage of the water-soluble flow packs is therefore not recognizable to the consumer.
  • the present invention was based on the object of providing a method for producing aesthetically appealing detergent or cleaning agent portions.
  • the process should be so variable that tablets as well as differently formulated detergent or cleaning agent compositions such as castings, powders, granules, extrudates, flakes, etc. can be packaged in an aesthetically pleasing manner.
  • it should be possible to produce portions which combine the advantages of the compactness of tablets with those of the quick solubility of portioned systems and, moreover, do not have to be provided with an outer packaging made of water-insoluble film.
  • the present invention therefore relates to a process for the production with water-soluble wrappings of tightly wrapped detergent or cleaning agent portions, which comprises the steps a) placing a water-soluble bottom film on a transport chain or a mold (s); b) placing one or more detergent or cleaning agent portion (s) on the lower film; c) placing a water-soluble top film on the detergent or cleaning agent portion (s) on the bottom film; d) fixing the top film to the bottom film including the detergent or cleaning agent portion (s); e) sealing and optional cutting of the foils is marked.
  • a water-soluble bottom film is provided, which is placed on a transport chain or a mold (s).
  • a combination of transport chain and mold (s) can also be used according to the invention.
  • Transport belts etc. are also understood as a transport chain in the sense of the present invention. Conveyor chains or belts are preferred over fixed molds for reasons of process economy.
  • a combination of transport chain and mold (s) is, for example, an assembly line that has recesses at regular intervals.
  • step a) of the process according to the invention a water-soluble film is placed over these molds, onto which one or more detergent or detergent portions are placed in the next process step.
  • the film which is placed on the transport chain or the mold (s) in step a).
  • the particles are spatially fixed, which facilitates the subsequent process steps.
  • Preferred methods according to the invention are characterized in that the bottom film is preformed by applying a vacuum and / or by heating. As a result, the film is provided with a cavity for receiving the particulate detergent or cleaning agent composition.
  • the procedure described above is not based on the Dosage of particulate compositions limited, but can also be used for the packaging of tablets according to the invention.
  • the water-soluble film is heated to temperatures above 50 ° C., preferably above 70 ° C. and in particular above 90 ° C., before being placed on the mold (s). This will make subsequent deformation easier.
  • the film can be heated further during the forming process. Process variants are preferred here in which the deformation of the water-soluble film is supported by heating the film to temperatures of 100 to 120 ° C. A combination of the two process variants, i.e. Placing a heated film and further heating is possible and preferred.
  • the film can also be pressed into the mold by metering the tablet or the particulate composition.
  • this is possible, for example, by placing an annular tool on the film placed over the mold and metering the particulate composition into the mold through this tube.
  • the film can either sink into the mold due to the mass of the composition, but the metering process can also be supported by pressing the composition into the mold, for example by means of a stamp in the tubular meter.
  • This dosage unit can also be used for tablets, but due to the compact molded body structure, the tablet can also be placed without it.
  • a particulate composition it can also be slightly pre-compressed to ensure that the mold is filled as completely as possible. If multiphase portions are to be produced, pressing on the first metered-in particulate composition ensures a flat interface between the two layers. Visually, such two-phase portions are closely based on the known two-layer tablets. The forces for pressing the particulate composition are selected so that the area of elastic deformation is not left. The dosing pressure does not lead to the particles sintering together (as would be the case with tableting), but only to the removal of bulk material cavities and to a flat surface. Methods according to the invention are preferred here, in which a Particulate premix is slightly compressed with the aid of the stamp, compression forces below 1 kN being preferred.
  • Slightly pre-compressed particulate compositions can also be easily lifted out of the mold before the sealing process without breaking immediately - this can be used advantageously for the position of the subsequent sealing seam, see below.
  • Preferred methods according to the invention for the coating of particulate compositions are characterized in that a further particulate detergent or cleaning agent is metered onto the first pre-compressed particulate washing or cleaning agent. This makes it possible to produce visually appealing portions.
  • step c) of the method according to the invention determines how high the composition protrudes from the film level.
  • the sealing seam is formed as a "brim" on one end face of the portion.
  • a simple plate can be used here for sealing, but this has the disadvantage that the film, which covers the top of the portion to which heat is applied.
  • the sealing seam can also be designed so that it runs along the outer surface of the portion.
  • the portion protrudes from the mold and another part of the portion protruding from the mold is covered with another film.
  • the sealing can now not be carried out with a plate-like sealing tool, but instead takes place with an annular tool.

  • it is also possible and preferred that it consists of a detergent or cleaning agent tablet or a casting with washing or cleaning active ingredients. Tablets and castings have the advantage that they can be placed exactly on the film and do not slip even when the film is transported on a flat conveyor belt or chain. Pile clusters can change their shape with this procedure.
