Definitions

  • the present invention relates to a detergent portion unit, comprising a gel body and a rigid enveloping substance at least partially covering the gel body.
  • the application also relates to a method for producing this detergent portion unit and a washing method for textiles or crockery using such a detergent portion unit.
  • water-soluble polymers are generally formed into receiving chambers, which are then filled with a detergent or cleaning agent and finally sealed.
  • the receiving chambers can be made, for example, from water-soluble polymer films by deep-drawing processes.
  • a water-soluble polymer is injection molded into a receptacle.
  • the water-soluble packaging material used to package the filled detergent portion units is generally hygroscopic.
  • the tendency and ability of the packaging to absorb water can result in portion units adhering to the surfaces of machines or packaging materials and being unable to be optimally conveyed, or in adjacent portion units, for example in a common outer packaging, glue together.
  • the powdering of the water-soluble detergent portion units in turn requires an additional process step.
  • the washing performance provided by the detergent portion unit is directly related to the dissolving properties of the portion unit. Precisely in view of the increasing use of cold washing processes, it is preferable to keep the thickness of the water-soluble film material contained in the detergent portion unit as small as possible in order to accelerate the dissolution process. At the same time, however, the reduction in the thickness of the surrounding film material results in reduced mechanical stability of the portion units. Overcoming this apparent dichotomy of mechanical stability and dissolution rate using water-soluble film-packaged detergent dosage units is still a relevant aspect in the development of water-soluble detergent portion units.
  • Detergent tablets offer an alternative to the sachets described above, in which however adequate mechanical stability and high dissolution rate are incompatible in a similar way as in the case of sachets.
  • the application was based on the object of providing detergent portion units that can be produced using simplified processes, have high product and storage stability, can be made up easily using very small amounts of packaging materials and are an appealing olfactory, visual and/or haptic appeal.
  • the detergent portion units should have a high product performance and be easy and safe to handle for the consumer.
  • a detergent supply form is suitable for solving these tasks, comprising a) outer packaging b) detergent tablets with an upper side, an underside and a lateral surface connecting the upper side and the lower side, with i) the outer packaging containing at least two detergent tablets which are sorted in the outer packaging and ii) the detergent tablets have a rough upper side or a rough underside, the average roughness of which is from 1 ⁇ m to 1000 ⁇ m, preferably from 10 ⁇ m to 800 ⁇ m and in particular from 25 to 500 ⁇ m.
  • the outer packaging is preferably designed as a folding box, particularly preferably 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 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, snap-in, 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.
  • a feature of preferred outer packaging is the COBB value of the cardboard used to produce it in the range below 25 g/m 2 , preferably below 20 g/m 2 .
  • the COBB value is a value that describes the resistance of paper and cardboard to moisture being drawn into the material.
  • a high COBB value means water is lighter penetrates.
  • a low COBB value means that it is difficult for water to penetrate the material.
  • the COBB value is determined according to DIN EN ISO 535 under 20 g/m2 at 20 °C and standard pressure.
  • Particularly preferred detergent supply forms are characterized in that the cardboard used to produce the outer packaging has a COBB value below 25 g/m 2 , preferably below 20 g/m 2 .
  • the outer packaging has, for example, a water-insoluble cover film, preferably a polyethylene cover film.
  • Water-insoluble cover films are generally suitable for preventing or at least reducing the entry of water or water vapor through the outer packaging into the interior of the outer packaging.
  • water-insoluble cover films are preferably only applied to the outside or inside of the outer packaging. Full-surface coverage is preferred to effectively limit the ingress of moisture.
  • detergent tablet describes a form of presentation in which a measured portion of a detergent or cleaning agent is present.
  • Detergent portion units therefore designate both forms of supply for textile laundry and forms of supply for cleaning hard surfaces such as ceramics, glass, metal or tiles.
  • a detergent tablet preferably weighs from 14 g to 42 g, preferably from 20 g to 38 g, in particular from 24 g to 34 g.
  • 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 tableting process.
  • a molding material e.g. a composition
  • the three-dimensional form of the detergent shaped body can in principle be freely selected; its lateral surface can, for example, be convex, concave or planar. At the same time, however, certain spatial configurations have proven to be particularly advantageous against the background of the producibility, storage and use of the gel bodies.
  • Correspondingly advantageous detergent tablets have a flat underside, the largest diagonal of which is greater than the height of the detergent tablet.
  • these bodies can also be packaged in a simple and space-saving manner and are suitable for dosing via the dosing or dispensing compartments of electronic cleaning devices. It is preferred if the gel body is a has a flat underside, the largest diagonal of which is 1.5 times, preferably more than 2 times, the height of the gel body.
  • the underside of the detergent tablet has no corners.
  • Preferred gel bodies are therefore characterized by oval undersides or alternatively by ellipsoidal or round, preferably round, undersides.
  • Corresponding detergent tablets with a non-angular underside are also preferred by many consumers because of their appearance. Preference is therefore given, for example, to detergent tablets which have an underside and an upper side which are connected to one another by a cylindrical lateral surface.
  • angular undersides are advantageous since such detergent tablets can be cut up without residues and can be packed in a space-saving manner.
  • preferred detergent tablets therefore have angular undersides, in particular triangular, quadrangular or hexagonal undersides.
  • detergent tablets which have an upper side that is plane-parallel to the underside have also proven to be advantageous.
  • the detergent tablet has an underside and an upper side which have the same geometric shape, the underside and the upper side having the same surface area.
  • Corresponding detergent tablets can, as already described above, be produced in a simple manner, for example by casting plates and then cutting the plates into individual detergent tablets.
  • these detergent shaped bodies can be spatially aligned more easily than gel bodies with a lower body symmetry due to the geometric identity of the top and bottom sides. This applies in particular to detergent tablets which at the same time have an upper side that is plane-parallel to the underside.
  • detergent tablets of this type are circular cylinders, elliptical cylinders, parallelepipeds, rhombohedrons, right or oblique prisms, cuboids or cubes.
  • the group of circular cylinders and elliptical cylinders includes the vertical circular cylinders and elliptical cylinders as well as the oblique circular cylinders and elliptical cylinders.
  • Detergent tablets are preferred due to their simple production by separating them from a sheet in the form of vertical circular cylinders, vertical elliptical cylinders, right prisms, right parallelepipeds or cubes.
  • the detergent tablet has an underside and an upper side which have the same geometric shape, the underside and the upper side having different surface areas.
  • Corresponding detergent tablets can be preferred due to their attractive appearance or their optimized fit, while at the same time being comparatively easy to produce. Examples of detergent tablets of this type are circular cylinders or elliptical cylinders with a convex or concave bottom and a flat top. Other examples are truncated cones or truncated pyramids.
  • the detergent shaped bodies are in the form of tablets or comprise tablets.
  • Particularly preferred detergent tablets are cuboid.
  • 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 advantageous for the stability of the tableted detergent tablets if the edges delimiting the underside and the upper side are chamfered. In order to increase the stability of these shaped bodies, it may also be advisable to round off the edges of the lateral surfaces connecting the undersides and the top sides.
  • the detergent shaped body comprises b1) a dimensionally stable gel body and b2) an encapsulating substance in the form of a tablet, which partially covers the surface of the dimensionally stable gel body.
  • Gel bodies are bodies that exhibit elastic deformation behavior under the action of force. Objects are considered dimensionally stable if they have an inherent dimensional stability that enables them to assume a non-disintegrating three-dimensional shape under the usual conditions of manufacture, storage, transport and handling by the consumer, with this three-dimensional shape also changing over longer periods under the conditions mentioned Time, preferably 4 weeks, particularly preferably 8 weeks and in particular 32 weeks, not changed, i.e. under the usual conditions of production, storage, transport and handling by the consumer in the spatial-geometric shape caused by the production , that is, does not flow.
  • the gel body and the enveloping substance are preferably adhesively bonded to one another.
  • the gel body preferably occupies at least 50% by volume, preferably at least 60% by volume, of the detergent supply form.
  • detergent tablets are preferred in which the gel component forms at least 16%, preferably at least 25% and in particular at least 30% of the total surface area of the detergent tablet.
  • the coating substance covers 10 to 70%, preferably 30 to 65% and in particular 40 to 60% of the surface of the gel body.
  • the water-soluble coating substance covers the surface of the gel body on two opposite sides of the gel body, since this makes it easier for the consumer to handle the detergent portion unit.
  • this type of surface covering has advantages with regard to the packaging of the detergent portion units, in particular when packaging several detergent portion units together, for example when the detergent portion units are stacked in an outer packaging.
  • detergent portion units in which 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. Both the underside and the upper side of the gel body are preferably covered to an extent of at least 40%, preferably at least 60% and in particular at least 80%.
  • the gel body has an underside and an upper side, and the water-soluble coating substance covers both the underside and the upper side of the gel body over the entire surface.
  • the detergent portion units according to the invention are particularly suitable for the formulation of surfactant-containing compositions, since these compositions tend to adhere and stick to a particular extent, for example, when exposed to moisture.
  • the gel body therefore contains 30 to 70% by weight, preferably 40 to 60% by weight and in particular 45 to 55% by weight of surfactant.
  • the gel bodies For the manufacturability and the subsequent dissolving power of the gel bodies, it has proven to be advantageous if they contain 15 to 35% by weight, preferably 20 to 30% by weight, of an aqueous-organic solvent.
  • Preferred gel bodies also contain dye.
  • Preferred detergent dosage units 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 20%, preferably above 30% and in particular above 35%.

  • the low molecular weight gelling agent has a solubility in water of less than 0.1 g/L (20° C.).
  • the solubility of the organic gelator compound is determined at 20°C in double-distilled, demineralized water.
  • gel formers are preferably suitable which have a structure containing at least one hydrocarbon structural unit with 6 to 20 carbon atoms (preferably at least one carbocyclic, aromatic structural unit) and additionally an organic structural unit covalently bonded to the aforementioned hydrocarbon unit, the at least two groups selected from -OH, -NH-, or mixtures thereof.
