Definitions

• the present invention relates to a detergent supply form, comprising outer packaging and detergent tablets, which are sorted and arranged in the outer packaging.
• the invention relates to detergent supply forms that have sorted detergent tablets that can be easily and safely removed by the consumer after opening the outer packaging.
• washing or cleaning agent dosing units for example water-soluble containers with one or more receiving chambers for powdered or liquid washing or cleaning agents.
• detergent tablets which can be single-phase or multi-phase.
• Both the water-soluble containers and the detergent tablets are usually hygroscopic due to the active ingredients they contain.
• the pre-portioned washing or cleaning agent dosage units are individually packaged using water-impermeable packaging means, for example flow packs based on water-insoluble polymer films.
• a plurality of washing or cleaning agent dosing units can be packaged in a container, which in turn has a water vapor barrier and in this way reduces the ingress of water to the dosing units.
• Transport and storage stability includes both ensuring the physical stability of the detergent or cleaning agent metering units, for example against breakage, and ensuring the chemical stability of the detergent or cleaning agent metering units, for example against premature reaction and decomposition of the three-dimensional shape caused by reaction.
• a classic approach to ensuring the transport and storage stability of detergent or cleaning agent tablets is to pack these tablets using individual flow pack packaging with three-sided weld seams and the fin seams that are characteristic of these flow packs.
• These flow packs are usually made from non-biodegradable, water-insoluble polymer films and, in addition to the detergent or cleaning agent dosing unit, also enclose a considerable volume of air.
• This air volume and the fin seams mentioned above guarantee the physical integrity of the dosing units under mechanical stress due to their dampening effect.
• the water-insoluble polymer films prevent undesired ingress of water from the ambient air and thus also chemically stabilize the detergent or cleaning agent dosing units.
• the application was based on the object of providing detergent portion units which can be produced using simplified processes, have high transport and storage stability and can be made up easily using very small amounts of packaging materials. Finally, the detergent portion units should have a high product performance and be easy and safe to handle for the consumer.
• the outer packaging is preferably designed as a folding box, in particular as a one-piece folding box.
• Preferred overwraps have a flat bottom surface whose longest diagonal is greater than the height of the overwrap. This configuration of the outer packaging increases its stability and enables it to be opened and removed easily.
• the outer packaging has a cornered bottom surface, preferably a square bottom surface, very particularly preferably a rectangular bottom surface.
• the outer packaging has a cover surface that is plane-parallel to the base surface. Outer packaging in the form of a parallelepiped is particularly preferred.
• the outer packaging is resealable.

• the outer packaging is made of cardboard.
• the advantages of cardboard lie in the great variability of the types and grammages available.
• Preferred cardboards have a grammage of 150 to 400 g/m 2 .
• Corrugated board which has proven to be technically superior to cardboard in some respects, is used in a particularly preferred embodiment for manufacturing the outer packaging.
• Corrugated cardboard is characterized by its low weight and high strength and is a suitable medium for storage and transport, even in large containers.
• An essential component of the detergent dosage form according to the invention are the detergent tablets.
• a "molding" is a single body that is self-stabilizing in its imposed shape. This dimensionally stable body is formed from a molding material (e.g. a composition) by bringing this molding material into a predetermined shape in a targeted manner, e.g. by pouring a liquid composition into a mold and then curing the liquid composition or by compressing a particulate premix, for example in as part of a tabletting process. It is particularly preferred if the detergent shaped bodies are in the form of tablets or comprise tablets.
• detergent tablets Both forms of supply for textile washing and forms of supply for cleaning hard surfaces such as ceramics, glass, metal or tiles are referred to as detergent tablets. Particular preference is given to detergent tablets, in particular detergent tablets for textile washing, since these are generally characterized by comparatively low hardness because of the need for rapid disintegration in the washing liquor.
• the detergent tablets preferably weigh from 14 g to 42 g, preferably from 20 g to 38 g, in particular from 24 g to 34 g.

• the roughness values preferred according to the invention reduce abrasion of the moldings during production and transport and at the same time ensure adequate adhesion of the moldings to the material of the outer packaging and the other moldings in the outer packaging, thereby stabilizing them within the outer packaging.
• An essential feature of the detergent dosage form according to the invention is its high degree of filling of 85 to 99% by volume of the outer packaging.
• This high degree of filling not only reduces the amount of packaging material that can be used per detergent tablet, but also surprisingly increases the physical stability of the detergent tablets, both with regard to tablet breakage and tablet abrasion.
• the degree of filling of preferred outer packaging is 85% by volume to 99% by volume, preferably 88% by volume to 99% by volume, particularly preferably 92% by volume to 99% by volume.

• the gel body preferably occupies at least 50% by volume, preferably at least 60% by volume, of the detergent supply form.
• Preferred gel bodies also contain dye.
• Preferred detergent tablets comprise a transparent gel body.
• Those gel bodies are referred to as "transparent" which have a transmission in the wavelength range from 410 to 800 nm at at least one wavelength, preferably at 600 nm, above 10%, preferably above 40% and in particular above 60%.

• the transmission is determined by means of VIS spectrometry at a sample temperature of 20° C. and a cuvette length of 10 mm.
• non-transparent shell materials especially when used in combination with transparent gel bodies, creates a product appearance that enables the consumer to distinguish between the surfaces covered by the shell substance and those that are not covered by the shell substance and the detergent portion unit, for example when removing it from the outer packaging , which comprises a plurality of detergent shaped bodies, specifically to grip the surfaces covered by the shell material and in this way to avoid direct contact with the gel body.
• preferred coating substances for example tablets, are white, ie not colored.
• the white color of the enveloping substance is suitable for printing.
• the enveloping substance can also be colored.

• the gel body and the enveloping substance have a color difference ⁇ E of more than 30, preferably more than 50. Colored enveloping substances can of course also be printed.
• the water-soluble coating substance for example in the form of two tablets, covers the surface of the gel on two opposite sides. It is particularly preferred if the gel body has an underside and an upper side and the water-soluble coating substance at least partially covers both the underside and the upper side of the gel body.
• this type of surface covering has advantages with regard to the packaging of the detergent tablets, in particular when packaging several detergent tablets together in an outer packaging, since in this way the risk of the gel phases of the tablets sticking to one another or to the outer packaging can be reduced.
• gel bodies which have an underside and an upper side and the coating substance covers both the underside and the upper side of the gel body by at least 40%, preferably at least 60% and in particular at least 80%. It is very particularly preferred if the enveloping substance covers both the underside and the upper side of the gel body over the entire surface.
• the degree of filling of the outer packaging can be optimized by a specific arrangement of the tablets.
• Detergent supply forms have proven to be advantageous in which the detergent tablets are arranged sorted in the outer packaging such that each of the detergent tablets is in direct contact with at least one other detergent tablet.
• the increased degree of filling and the direct contact can also improve their tendency to fracture and abrasion and improve the transport stability of the shaped bodies.
• Preferred detergent tablets have surfaces of different roughness. Different surface roughnesses enable the consumer to differentiate between the tactile properties of the shaped body surfaces and improve product safety when removing the product. This applies in particular to detergent tablets which do not have separate film packaging.
• Preferred detergent tablets have a rough upper side or a rough underside with an average roughness of from 25 ⁇ m to 1000 ⁇ m, preferably from 50 ⁇ m to 800 ⁇ m.

• Preferred webs have a height which is 5 to 80%, preferably 10 to 60% and in particular 20 to 50% of the shortest distance between the two end faces of the detergent tablets.
• the detergent tablets can have a separate film packaging.
• the water-soluble film material may comprise one or more structurally distinct water-soluble polymer(s).
