Definitions

  • the present invention is in the field of portioned compositions which preferably have washing and cleaning-active properties.
  • Such detergent and cleaning agent portions include, for example, portioned agents for washing textiles, portioned detergents for machine dishwashing or cleaning hard surfaces, portioned bleaches for use in washing machines or dishwashers, portioned water softeners or stain salts; these individual forms of supply are summarized below under the term “detergent or cleaning agent portion”.
  • the invention relates to washing and cleaning agent portions that are used for the automatic cleaning of dishes in household dishwashers.
  • 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.
  • Tableted detergents and cleaning agents have a number of advantages over powdered ones: They are easier to dose and handle and, thanks to their compact structure, have advantages during storage and transport. Detergent tablets are consequently also extensively described in the patent literature.
  • a problem that occurs again and again when using shaped articles which are active in washing and cleaning is the insufficient rate of disintegration and dissolution of the shaped articles under conditions of use. Since sufficiently stable, that is to say molded and break-resistant molded articles can only be produced by relatively high compression pressures, there is a strong compression of the molded article components and consequently a delayed disintegration of the molded article in the aqueous liquor and thus to a slow release of the active substances in the Washing or cleaning process.
  • the delayed disintegration of the shaped bodies has the further disadvantage that many washing and cleaning agent shaped bodies cannot be washed in via the washing-in chamber of household washing machines, since the tablets do not disintegrate into secondary particles which are small enough to be washed into the washing drum from the washing-in chamber to become.
  • This dichotomy between hardness (ie manageability) and decay only plays a subordinate role in packaged detergent or cleaning agent portions. Rather, phenomena such as the solubility or disintegrability of the packaging come to the fore, while the packaged detergent or cleaning agent only plays a role with its physical properties if a tablet has been packaged.
  • filled tubular bags have little aesthetic appeal. The consumer only accepts this form of offer very little and does not trust the corresponding product to have a high level of performance. If only one uniform composition is packed in a bag, multifunctional advantages of the agents cannot be visualized.
  • the prior art therefore discloses packaging made of water-soluble materials which are not in the form of tubular bags but are produced by processes such as injection molding or deep drawing. These more rigid bodies are filled - similar to yoghurt cups - and sealed after filling.
  • another composition e.g. a powder, a liquid or a melt
  • the pack can separate in an uncontrolled manner, which leads to problems with the closure of the filled hollow articles and to leads to aesthetic inconvenience.
  • the object of the present invention was to provide aesthetically appealing detergent or cleaning agent portions which combine the advantages of the compactness of tablets with those of the quick solubility of portioned systems.
  • Larger solid bodies (“cores”) ie solid bodies, which differ significantly in size from particulate, should be used Lift off compositions and have, for example, minimum diameters above 2 mm, can be incorporated without causing technical or aesthetic disadvantages.
  • cores can be introduced into water-soluble portion packs and can be surrounded with flowable material if they are fixed to the water-soluble casing before being filled with flowable material.
  • the present invention relates to a portion packaging comprising a water-soluble envelope and at least one core located therein and a matrix of flowable material at least partially surrounding the core (s), in which the core (s) on the water-soluble covering is / are fixed.
  • portion packaging and “detergent or cleaning agent portion” are used without, where “detergent or cleaning agent portion” stands, other portion packaging according to the invention is not to be excluded. Rather, the portion packaging according to the invention is also suitable for others Areas of application such as pesticides, pharmaceuticals, cosmetics, etc.
