Definitions

  • the subject matter of the present application is a process for producing solid multi-phase WC cleaning blocks which consist of at least two phases.
  • Detergents and disinfectants have long been used in the toilet bowl under the edge of the pool (so-called rim blocks) as well as in the water tank (in- tank-biocks or cistern blocks).
  • the formulations generally contain surfactants, disinfectants and bleaches, salts, acids, complexing agents, fillers, dyes and perfumes, Ab Pattersonregulatoren and / or other components.
  • the ingredients are usually mixed, compressed and then extruded to Strän ⁇ gene. The strands are finally cut to the desired length and optionally placed in toilet bowls.
  • the toilet bowl can be cleaned and / or disinfected, for example. Furthermore, e.g. It is also possible to inhibit unpleasant odors or fragrance with a perfume.
  • the ingredients needed for these various effects are not always compatible with each other. For example, sensitive substances, such as dyes, can be attacked, for example, by antimicrobial bleaching agents; Also, the compatibility of acids or complexing agents, which are used to prevent lime, rust or urinary stone deposits, for example, with perfumes is often not given.
  • Such multi-use toilet sticks are therefore advantageously designed as multi-phase sticks.
  • the different phases can be equipped with different colors in order to signal the multiple benefit to the consumer as well. In this case, the different phases can be arranged either horizontally above one another or vertically next to or behind one another.
  • Polyphonic WC sticks have so far been produced in a single manufacturing process by co-extrusion of the different phases.
  • the various strands are brought together immediately after extrusion, pressed together and cut.
  • EP 1 165 740 B1 describes a toilet cleaning block comprising at least two phases, one phase of which contains a water-insoluble salt which makes up at least 50% by weight of the salt in this phase, and the second phase of which is a perfume and a water-soluble one Contains salt, wherein the salts in both phases should have the same anion. Other ingredients may also be included.
  • the manufacturing process also claimed is the coextrusion of the two or more phases to form the block.
  • EP 0 791 047 B1 also describes multi-phase cleaning agent pieces for flushing toilets, which, however, are configured in such a way that one phase is enclosed by a second and, if appropriate, further phases.
  • all phases can be extruded or extruded at least one phase and at least one further phase are poured, the latter in particular for liquid cores. If all phases are extruded, two or more extruders are needed, the strands of which are brought together and then cut, with a two-component or multi-component nozzle for the common extrusion of the phases enclosing each other can be used.
  • the object of the present invention was thus the development of a process for simplified production of multiphase WC sticks, which do not have the disadvantages mentioned with the same visual impression.
  • the invention therefore relates to a process for producing solid multi-phase WC cleaning block, consisting of at least two phases, characterized by the steps of mixing the components in each case for the individual phases, extrusion of the individual strands for the different phases, trimming the strands on the for the length of individual blocks, combining the blocks for the various phases and finally fixing in a water-soluble, transparent film.
  • a second subject of this invention is a multi-phase WC cleaning block which requires only one extruder to produce.
  • This toilet cleaning block is inserted into a water-soluble polyvinyl alcohol (PVAL) film.

  • Another subject of the invention is therefore a product of a multi-phase toilet cleaning block and a transparent container.

  • the can length of the longer edges of the cuboids for the individual phases is not more than twice as large as that of the shorter edges. If three or more phases are combined to form a block, they can all be arranged one above the other, all next to each other or both above and next to each other.
  • two phases may be arranged next to or behind one another and rest on a third block, the dimensions of which are preferably chosen such that complete coincidence occurs on the common area with the other two phases.

Abstract

L'invention concerne un procédé pour produire un bloc de nettoyage de W.-C., solide, à phases multiples, constitué d'au moins deux phases. Ce procédé est caractérisé en ce qu'il comprend les étapes suivantes: mélange des composants pour chaque phase individuelle; extrusion des boudins individuels pour les différentes phases; découpage des boudins à la longueur requise pour les blocs individuels; regroupement des blocs pour les différentes phases et fixation dans un film transparent hydrosoluble. On obtient ainsi des blocs de nettoyage de W.-C. à plusieurs phases dont la production ne requiert qu'une seule extrudeuse. Les blocs peuvent être vendus sous forme d'un produit associé à un contenant transparent.
