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 which have sorted detergent tablets and outer packaging with high filling levels.
• 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.
• the concept of transport and storage stability includes ensuring physical stability of the detergent or cleaning agent dosing units, for example against breakage, and ensuring the chemical stability of the detergent or cleaning agent dosing 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 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. It is particularly preferred if the Overpack has a flat bottom surface, the largest diagonal of which is more than twice, preferably more than four times, the height of the overpack.
• 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.
• adhesive, latching, snap-in or plug-in elements are suitable as closure elements, with adhesive and plug-in elements being particularly preferred.
• closure elements are plug-in closures or removable adhesive closures.
• the packaging materials are preferably based on renewable raw materials.
• the use of packaging materials based on cellulose and waste paper is particularly preferred.
• 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.
• the outer packaging is designed as a box with a hinged lid.
• 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 compound (eg a composition) by specifically bringing this molding compound into a predetermined shape, for example by pouring a liquid composition into a mold and subsequent curing of the liquid composition or by compressing a particulate premix, for example in a tableting process.
• a molding compound eg a composition
• 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.
• Detergent tablets which have a flat underside, the largest diagonal of which is more than twice, preferably more than four times, the height of the detergent tablets are preferred due to their producibility and their removal properties from the outer packaging.
• the detergent shaped bodies are in the form of tablets or comprise tablets.
• the cuboid shaped detergent bodies comprise an underside, an upper side and a lateral surface connecting the underside and the upper side. It has also proven to be advantageous for the stability of the moldings if the edges delimiting the underside and the upper side are chamfered. In order to increase the stability of the moldings, it may also be advisable to round off the edges of the lateral surfaces connecting the undersides and the upper sides.
• the density of preferred detergent tablets is 1.1 g/cm 3 to 1.5 g/cm 3 , preferably 1.15 g/cm 3 to 1.3 g/cm 3 .

• 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.
• the roughness describes the deviation of a real surface from an ideally smooth surface and is determined, for example, using confocal laser scanning microscopy.
• 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 88% by volume and 99% by volume, preferably 92% by volume and 99% by volume.
• the “degree of filling” refers to that proportion of the inner volume of the outer packaging which is occupied by the detergent tablets located in the outer packaging.
