  • Cleaning agents are usually available in solid form or in liquid form (or as a flowing gel). Liquid cleaning products in particular are becoming increasingly popular with consumers.
  • Solid cleaning agents have the advantage that, unlike liquid cleaning agents, they do not require any preservatives. Liquid forms are increasingly gaining ground on the market, particularly due to their rapid solubility and the associated rapid availability of the active ingredients they contain.

  • the spatial shape of the shaped body is fundamentally freely selectable; its lateral surface can, for example, be designed to be convex, concave or flat. At the same time, however, certain spatial configurations have proven to be particularly advantageous in terms of the manufacturability, storage and use of the molded bodies.

  • the shaped bodies can be used in terms of their spatial shape or their Composition may be identical or differ, for example, in terms of their composition or spatial shape.
  • the shaped bodies can be arranged one above the other or next to one another and will generally be in contact with one another. Several shaped bodies can also be in direct contact with the closure element. If the inside of the closure element is covered to a certain extent of its surface by moldings, as described below, the degree of coverage refers to the coverage caused by the totality of the moldings contained in the single-use cleaning agent portion.
  • the molded body which is in contact with the closure element, has a height of 2.5 to 9 mm, preferably 2.75 to 6.0 mm, in particular 3.0 to 5.5 mm.
  • Such shaped bodies are particularly suitable for utilizing the available space in the receiving chamber in combination with the powder and at the same time achieving the advantages of covering the powder compared to the closure element.
  • the entire single-use cleaning agent portion is stabilized by the presence of such shaped bodies.
  • Shaped bodies with significantly lower heights than specified are generally more sensitive to breakage, which means that they cannot fulfill the purpose according to the invention right from the start or not over the entire transport and/or storage period.
  • Much thicker shaped bodies have the disadvantage that they leave too little space in the space used for the single-use cleaning agent portion for other important components that cannot be incorporated into the shaped body without greater effort and/or loss of activity.

  • the shaped body is essentially the same thickness.

  • the molded body has a substantially flat top and bottom side, the top side being in essentially full-surface contact with the closure elements.
  • a preferred arrangement according to the invention is that less than 10% of the surface of the inside of the closure element is in contact with the powder. This is advantageous for the efficient, especially trouble-free production, strength of the closure between the receiving chamber and the closure element, and the optical properties of the single-use portion, since in this case there is less chance for the powder to get onto the closure surfaces, e.g. in the case of deep-drawn receiving chambers, directly onto the surfaces next to the trained chamber.
  • the stability of the single-use portion in particular during storage and/or transport, can also be improved in that the powder, if it has only a small amount of contact with the inside of the closure element, does not injure the closure element, bulge or even bulge in some places punctures or wears away and/or wears through due to prolonged friction. If the contact of the powder with the inside of the closure element is reduced or avoided, the thickness of the closure element, e.g. B. the thickness of the closure film can be chosen to be smaller, which is advantageous in terms of sustainability by using less packaging material.
  • the single-use cleaning agent portion contains exactly one shaped body, which according to the invention is arranged so that it is in direct contact with the closure element.

  • the inside of the closure element is in contact with the powder to less than 8%, in particular to less than 6%, and most particularly to less than 3% of its surface.
  • the shaped body according to the invention is a preformed shaped body.
  • a preformed molded body has already received its shape before it is introduced into the receiving chamber.
  • the production of the shaped body is decoupled from the production of the single portion (particularly in terms of time).
  • the production steps of the entire single-use cleaning agent portion can therefore be carried out in quick succession and are not extended by the solidification times of the shaped body, which are necessary if this shaped body is produced in situ, for example when it is introduced into the receiving chamber as a flowable premix.
  • ingredients that are not incorporated into gel phases in particular those that are introduced into the receiving chamber as a flowable composition as a flowable composition, can also be incorporated into the moldings that are preformed due to the processability of the ingredients themselves, the manufacturing process of the gel phases, and/or their material properties can be.
  • at least one shaped body must be arranged in such a way that it is in direct contact with the closure element and less than 10% of the surface of the inside of the closure element is in contact with the powder.
  • the inside of the closure element is not in contact with the powder.
  • the shaped body is arranged in the chamber so that it is in direct contact with the powder.
  • the shaped body can cover the powder well so that it does not come into contact with the inside of the closure element and possibly impair the tightness of the closure of the single-use portion.

  • This can be done in particular by bringing the shaped body onto or into the receiving chamber from above after filling the powder into the receiving chamber.
  • the shaped body then covers the phase formed by the powder to a large extent and at least largely prevents the powder from coming into contact with the surface of the inside of the closure element after the single-use cleaning portion has been closed. The previously described negative consequences of large-area contact of the surface with the powder are thereby avoided.
  • the closure element rests on the molded body during direct contact.
  • the side of the shaped body which is in contact with the closure element has at least 70%, preferably at least 75%, in particular at least 80%, particularly preferably more than 85% of its surface in contact with the inside of the closure element.
  • This embodiment has the advantage that this arrangement prevents particles of the powder from getting between the closure element and the molded body after production, for example during transport. The above-mentioned problems of chafing, piercing, etc. are thereby further reduced.
  • This side of the molded body particularly preferably has essentially full-surface contact with the closure element.
  • Essentially full-surface means that at least 90% of the surface of the contact side is in direct contact with the inside of the closure element Contact is established. The closure element then rests on the molded body during direct contact.
  • the shaped bodies according to the invention preferably have a flat underside, the largest diagonal of which is greater than the height of the shaped body.

  • the shaped body has an upper side that is essentially plane-parallel to the underside.
  • Essentially plane-parallel surface means that deviations from complete parallelism of approximately 10%, preferably 5%, are still possible. Such surfaces are caused by production deviations or certain production processes and, for example, show slightly roughened, bumpy surfaces. However, such surfaces are included according to the invention.
  • This configuration advantageously means that a flat closure element (in particular a flat, water-soluble film) can be easily applied to a plane-parallel top side.

  • the thickness of the film can be reduced because the above-mentioned negative effects due to the powder do not occur, since there is little contact with the powder .
  • This has the advantage that, for the environmentally friendly, sustainable use of packaging material, a film can be selected that has a smaller thickness than that used for conventional water-soluble single-use portions.
  • the water-soluble film has a thickness of 80 pm or less, preferably 70 pm or less, in particular 65 pm or less, particularly preferably 60 pm. Most preferably, the thickness of the film can be 55 ⁇ m or less, which leads to a significant saving in packaging material.
  • the water-soluble film forming the closure element has a thickness smaller than the average thickness of the water-soluble receiving chamber.
