Definitions

• the present invention relates to a detergent supply form, comprising an outer packaging and detergent tablets, which are arranged sorted 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 or abrasion, 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 overpacks have a flat bottom surface with a greater diagonal than that height of the outer packaging. This configuration of the outer packaging increases its stability and enables it to be opened and removed easily. It is particularly preferred if the outer packaging has a flat bottom surface, the largest diagonal of which is more than twice, preferably more than four times, the height of the outer packaging.
• 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.
• corrugated board in connection with the present invention is its hollow volume.
• the design of the side walls of the outer packaging including cavities has surprisingly proven to be advantageous for the physical stability of the detergent tablets.
• at least one of the side walls has a void volume which is at least 10% by volume of the volume of the side wall.
• a further improved stabilization of the detergent tablets can be achieved if at least two of the side walls have cavities which are at least 10 % by volume of the volume of the respective side wall, it being particularly advantageous if two opposing side walls of the outer packaging have hollow volumes which amount to at least 10% by volume of the volume of the respective side wall.
• Detergent supply forms in which all side walls of the outer packaging have hollow volumes which amount to at least 10% by volume of the volume of the respective side wall are very particularly preferred.
• the detergent tablets are preferably arranged in the outer packaging in such a way 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 hollow volume which is at least 10% by volume of the volume of the side wall.
• the chemical stability of the detergent tablets is surprisingly also favored by the integration of hollow volumes in the side walls of the outer packaging.
• a conceivable explanation is that the ingress of water from the outside into the interior of the outer packaging is made more difficult by the hollow volume interrupting the material of the side walls and/or the hollow volume in the side walls buffers the ingress of moisture.
• particularly preferred outer packaging has one or more side walls in which the hollow volume is at least 20% by volume, preferably at least 40% by volume, of the volume of the respective side wall.
• the hollow volume in the side walls of the outer packaging can be realized, for example, by using corrugated cardboard.
• a preferred alternative or supplement to corrugated cardboard is carded boxes or hollow-sided boxes, which, due to their structure, are suitable for realizing hollow volumes in the range of 10% by volume and higher.
• 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 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 to 99% by volume, preferably 92% by volume to 99% by volume.
• the “degree of filling” is that proportion of the inner volume of the outer packaging that is occupied by the detergent tablets in the outer packaging.
• Detergent tablets are both forms of supply for textile washing and forms of supply for cleaning hard surfaces such as ceramics, glass, metal or tiles. Detergent tablets for laundry are particularly preferred, since these are usually characterized by a comparatively low tablet hardness due to 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 tablet are preferred because of their manufacturability and their removal properties from the outer packaging.
• the cuboid detergent tablets are arranged in the outer packaging in such a way that the axes of rotation of the detergent tablets, along which they have the lowest tablet hardness, run parallel to the bottom surface of the outer packaging.
• This type of arrangement is particularly advantageous in the case of cuboid detergent tablets which have three twofold axes of rotation, with the tablet hardnesses which the detergent tablets have along these three axes of rotation differing from one another.
• the cuboid detergent tablets have three twofold axes of rotation and the lowest tablet hardness that the detergent tablets have along one of these three axes of rotation is at least 20%, preferably at least 40% and in particular at least 60% below the next higher tablet hardness along one of the two remaining axes of rotation .
• the tablet hardnesses which the cuboid detergent tablets have along their three twofold axes of rotation, are preferably from 50 N to 300 N, preferably from 70 N to 200 N.
• the hardness of the tablets is measured by deforming the tablet until it breaks, applying the force to the side faces of the tablet and determining the maximum force that the tablet can withstand.
• a tablet testing device from Sotax, for example, is suitable for determining tablet hardness.
• edges delimiting the underside and the upper side are chamfered.
• 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 .
• the detergent supply forms according to the invention have comparatively high densities, for example densities in the range from 0.9 g/cm 3 to 1.4 g/cm 3 , preferably in the range from 1.05 g/cm 3 to 1.3 g/cm 3 .
• Preferred detergent tablets have a rough upper side or a rough underside, the mean roughness of which is 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 tablets during production and transport and at the same time ensure adequate adhesion of the tablets to the material of the outer packaging and the other tablets in the outer packaging, thereby stabilizing them within the outer packaging.
• the detergent tablets can have film packaging, it being particularly preferred if each of the detergent tablets has separate film packaging.
• the water-soluble film material may comprise one or more structurally distinct water-soluble polymer(s).
• Particularly suitable as water-soluble polymer(s) are polymers from the group of (possibly acetalized) polyvinyl alcohols (PVAL) and their copolymers.
• Water-soluble film materials are preferably based on a polyvinyl alcohol or a polyvinyl alcohol copolymer whose molecular weight is in the range from 10,000 to 1,000,000 gmol -1 , preferably from 20,000 to 500,000 gmol -1 , particularly preferably from 30,000 to 100,000 gmol -1 and in particular from 40,000 to 80,000 gmol -1 lies.
• the preparation of the polyvinyl alcohol and polyvinyl alcohol copolymers typically involves the hydrolysis of intermediate polyvinyl acetate.
• Preferred polyvinyl alcohols and polyvinyl alcohol copolymers have a degree of hydrolysis of 70 to 100 mol %, preferably 80 to 90 mol %, particularly preferably 81 to 89 mol % and in particular 82 to 88 mol %.
• preferred polyvinyl alcohol copolymers include an ethylenically unsaturated carboxylic acid, its salt or its ester.
• Such polyvinyl alcohol copolymers particularly preferably contain, in addition to vinyl alcohol, sulfonic acids such as 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS), acrylic acid, methacrylic acid, acrylic esters, methacrylic esters or mixtures thereof; among the esters, C 1-4 -alkyl esters or - hydroxyalkyl esters are preferred.
• AMPS 2-acrylamido-2-methyl-1-propanesulfonic acid
• Other monomers are ethylenically unsaturated Dicarboxylic acids, for example itaconic acid, maleic acid, fumaric acid and mixtures thereof.
• film packaging which consists of at least 40% by weight, preferably at least 60% by weight and in particular at least 80% by weight of polyvinyl alcohol.
• the detergent tablets in the detergent dosage forms according to the invention have proven to be unexpectedly stable. This also applies in particular to detergent tablets, which tend to have reduced transport and storage stability due to their hygroscopicity, for example due to the integration of tablet disintegrants.
• Detergent tablets which are particularly suitable for packaging in the detergent forms according to the invention are in particular detergent tablets which have a water absorption (2 weeks, 35° C., 80% relative humidity) above 20 mg/g, preferably above 30 mg/g.
• Detergent tablets which have a volume expansion (2 weeks, 35°C, 80% relative humidity) above 5% by volume, preferably above 7% by volume and in particular from 8% by volume to 18 Have % by volume.
• This type of increase in volume can be observed, for example, in detergent tablets which contain a disintegration aid, in particular a polymeric disintegration aid, for example a disintegration aid based on polyvinylpyrroledione or cellulose.
• the detergent supply form comprises at least ten, preferably at least twenty, particularly preferably at least thirty detergent tablets, which are arranged in the outer packaging in such a way that the axis of rotation of the detergent tablets, along which they have the lowest tablet hardness, is parallel to the bottom surface of the outer packaging.
• Detergent supply forms that have proven to be advantageous include at least ten, preferably at least twenty, particularly preferably at least thirty detergent tablets, which are sorted in the outer packaging such that each of the detergent tablets is in direct contact with at least three other detergent tablets.
• the detergent supply form comprises at least ten, preferably at least twenty, particularly preferably at least thirty detergent tablets, which are arranged in the outer packaging in such a way that the axis of rotation of the detergent tablets, along which they have the lowest tablet hardness, is parallel to the bottom surface of the outer packaging run and this axis of rotation coincides with at least one axis of rotation of the lowest tablet hardness of a detergent tablet that is in direct contact.
• the packs contain at least ten, preferably at least twenty and in particular at least forty of the detergent dosage forms according to the invention.
