Definitions

• the present invention relates to a detergent packaging form comprising an outer package and detergent tablets arranged in assorted form within the outer package.
• the invention relates to detergent packaging forms comprising assorted detergent tablets and outer packages with high fill levels.
• detergents and cleaning agents are subject to constantly changing requirements. For some time now, a major focus has been on convenient dosing by the consumer and simplifying the steps required for washing or cleaning.
• pre-portioned detergent or cleaning agent dosing units such as water-soluble containers with one or more compartments for powdered or liquid detergents or cleaning agents.
• detergent tablets which can be single-phase or multi-phase.
• Both water-soluble containers and detergent tablets are generally hygroscopic due to the active ingredients they contain.
• the pre-portioned detergent or cleaning agent dosing units are individually packaged using waterproof packaging materials, such as flow packs based on water-insoluble polymer films.
• multiple detergent or cleaning agent dosing units can be packaged in a single container, which itself has a water vapor barrier, thus reducing water access to the dosing units.
• one goal of developing innovative detergent packaging formats is to provide solutions and designs that, based on recycled, recyclable, or biodegradable materials, realize the technical advantages of non-recyclable, non-biodegradable, or non-biodegradable materials to the greatest extent possible. Optimizing and further developing existing sustainable technical solutions offers a starting point for this development.
• transport and storage stability includes ensuring physical stability.
• the protection of detergent or cleaning agent dosing units, for example against breakage or abrasion, as well as ensuring the chemical stability of the detergent or cleaning agent dosing units, for example against premature decomposition and deterioration of the shape caused by decomposition, are crucial.
• a classic approach to ensuring the transport and storage stability of detergent or cleaning agent tablets involves packaging these tablets in individual flow packs with three-sided welds and the characteristic fin seams of these flow packs.
• These flow packs are generally made of 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 aforementioned fin seams ensure the physical integrity of the dosing units under mechanical stress due to their damping effect. Furthermore, the water-insoluble polymer films prevent unwanted water ingress from the ambient air and thus also chemically stabilize the detergent or cleaning agent dosing units.
• Packaging systems with an octagonal base for tablet-shaped items are described in the international patent application. WO 2004/058580 A1 described.
• German patent application DE 100 18 003 A1 It concerns packaging for cylindrical detergent tablets.
• Cuboid-shaped washing or cleaning agents are listed in the international application WO 2004/046297 A1 and in the granted patent US 4,996,000 revealed.
• the application aimed to provide detergent portion units that can be manufactured using simplified processes, possess high transport and storage stability, and can be easily packaged using minimal amounts of packaging material.
• the detergent portion units should offer high product performance and be easy and safe for the consumer to handle.
• a detergent offering form according to claim 1 is suitable for solving these tasks.
• the outer packaging is preferably designed as a one-piece folding carton.
• Preferred outer packaging has a flat base whose largest diagonal is greater than the height of the outer packaging. This design of the outer packaging increases its stability and allows for easy opening and removal. It is particularly preferred if the outer packaging has a flat base whose largest diagonal is more than twice, preferably more than four times, the height of the outer packaging.
• the outer packaging To achieve a high fill level, it has proven advantageous for the outer packaging to have a rectangular base. For the same reason, and to improve the stackability of the outer packaging, it is preferred that the outer packaging has a lid surface that is parallel to the base. Cuboid-shaped outer packaging is particularly preferred.
• Suitable closure elements include, for example, adhesive, snap, or plug-in elements, with adhesive and plug-in elements being particularly preferred.
• closure elements are snap closures or releasable adhesive closures.
• the packaging materials are based on renewable raw materials.
• the use of packaging materials based on pulp and recycled paper is particularly preferred.
• the outer packaging is made of cardboard. Besides its availability and recyclability, the advantages of cardboard lie in the wide variety of available grades and basis weights. Preferred cardboards have a basis weight of 150 to 400 g/ m2 .
• Corrugated board which has proven technically superior to cardboard in some respects, is used in a particularly preferred embodiment for the manufacture of the outer packaging. Corrugated board is characterized by high strength despite its low weight and is a suitable material for storage and transport, even in large containers.
• a further significant technical advantage of corrugated cardboard in connection with the present invention is its void volume.
• Designing the side walls of the outer packaging to include voids has proven surprisingly advantageous for the physical stability of the detergent tablets.
• at least one of the side walls has a void volume of at least 10% by volume of the side wall's volume.
• Further improved stabilization of the detergent tablets can be achieved if at least two of the side walls have void volumes of at least 10% by volume of the respective side wall's volume. It is particularly advantageous if two opposing side walls of the outer packaging have void volumes of at least 10% by volume of the respective side wall's volume.
• Detergent packaging formats in which all side walls of the outer packaging have void volumes of at least 10% by volume of the respective side wall's volume are especially preferred.
• the detergent tablets are arranged in the outer packaging such that the axes of rotation of the detergent tablets, along which they have the lowest tablet hardness, are orthogonal to a side wall of the outer packaging which has a cavity volume which is at least 10 vol. %, of the volume of the side wall.
• the chemical stability of the detergent tablets is surprisingly also enhanced by the integration of cavities into the sidewalls of the outer packaging.
• the cavities which interrupt the material of the sidewalls, hinder water from penetrating the outer packaging and/or that the cavities in the sidewalls buffer moisture ingress.
• particularly preferred outer packagings have one or more side walls in which the void volume is at least 20 vol.%, preferably at least 40 vol.% of the volume of the respective side wall.
• the hollow volume in the side walls of the outer packaging can be achieved, for example, by using corrugated cardboard.
• a preferred alternative or complement to corrugated cardboard are hollow-edge boxes or boxless boxes, which, due to their design, are suitable for achieving hollow volumes of 10% by volume and higher.
• a key feature of the detergent packaging format according to the invention is its high fill level of 85 to 99% by volume of the outer packaging.
• This high fill level not only reduces the amount of packaging material used per detergent tablet, but also surprisingly increases the physical stability of the detergent tablets, both in terms of With regard to tablet breakage as well as tablet abrasion, the fill level of preferred outer packaging is 88% to 99% by volume, preferably 92% to 99% by volume.
• “Fill level” refers to the proportion of the inner volume of the outer packaging occupied by the detergent tablets contained therein.
• detergent tablets refers to both those for washing textiles and those for cleaning hard surfaces such as ceramics, glass, metal, or tiles.
• Detergent tablets for washing textiles are particularly preferred because, due to the need for rapid disintegration in the wash water, they are generally characterized by a comparatively low tablet hardness. These tablets preferably weigh between 14 g and 42 g, more preferably between 20 g and 38 g, and particularly between 24 g and 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 tablet, are preferred.
• the cuboid detergent tablets are arranged in the outer packaging such that the axes of rotation of the detergent tablets, along which they exhibit the lowest tablet hardness, run parallel to the base of the outer packaging.
• This type of arrangement is particularly advantageous in the case of cuboid detergent tablets that have three twofold axes of rotation, wherein the tablet hardnesses exhibited by the detergent tablets along these three axes of rotation differ from one another.
• the cuboid detergent tablets have three twofold axes of rotation, and the lowest tablet hardness exhibited by the detergent tablets along one of these three axes of rotation is at least 20%, preferably at least 40%, and particularly at least 60% lower than the next highest tablet hardness along one of the two remaining axes of rotation.
• the tablet hardnesses exhibited by the cuboid detergent tablets along their three two-fold axes of rotation are preferably from 50 N to 300 N, more preferably from 70 N to 200 N.
• the lowest tablet hardness exhibited by the detergent tablets along one of their three axes of rotation is preferably in the range of 50 N to 150 N, more preferably from 60 N to 130 N.
• the tablet hardness is measured by deforming the tablet until it breaks, whereby the force acts on the tablet's side surfaces and the maximum force the tablet can withstand is determined.
• a tablet testing device from Sotax, for example, is suitable for determining the tablet hardness.
• the density of preferred detergent tablets is 1.1 g/ cm3 to 1.5 g/ cm3 , preferably 1.15 g/ cm3 to 1.3 g/ cm3 .

• Preferred detergent tablets have a rough top or bottom surface with an average roughness of 25 ⁇ m to 1000 ⁇ m, preferably 50 ⁇ m to 800 ⁇ m.
• Roughness describes the deviation of a real surface from an ideally smooth surface and is determined, for example, by confocal laser scanning microscopy.
• the roughness values preferred according to the invention reduce the abrasion of the tablets during manufacture and transport and at the same time ensure sufficient adhesion of the tablets to the material of the outer packaging and to the other tablets in the outer packaging, thereby stabilizing them within the outer packaging.
• the detergent tablets may have a foil wrapper, and it is particularly preferred if each detergent tablet has a separate foil wrapper.
