Description

The invention relates to a detergent product, in particular for textile treatment, more particularly for textile cleaning and/or for textile laundry, with a film bag having a plurality of bag chambers, each of which is enclosed by a water-soluble film, the bag chambers being connected to one another in a sealing plane Foils are formed and are separated from one another by sealing sections lying in the sealing plane and the bag chambers are each filled with a detergent preparation, at least one central chamber arranged in the central region of the foil bag being provided, which is filled with a detergent preparation, and the bag chambers arranged around the central chamber are, whereby the detergent preparation with which the central chamber is filled is transparent and achromatic.

Water-soluble detergent products in the format of a disposable portion pack for textile treatment, in particular in the form of foil bags, so-called pouches, are known. Such a portion pack is used for a one-time textile treatment application, usually within a textile washing machine. The detergent product has a foil bag with one or more bag chambers. Consumer surveys and market research show that consumers generally prefer products with multiple chambers over products with only one or fewer chambers. In general, the popularity of such multi-chamber products in a unit dose format has increased significantly in recent years and now accounts for a significant market share in many European countries.

Each bag compartment of such detergent products contains a detergent preparation which contains detergent-active substances for textile treatment, in particular for textile laundry. The use of several bag chambers opens up the possibility of separately storing different detergent preparations, which may react chemically with one another or are not stable in storage when mixed for other reasons. In addition, the use of several, different detergent preparations within one washing process allows the release of several, functionally different detergent and/or additive substances, such as bleach, fabric softeners or fragrances. If several bag chambers are provided, the individual detergent preparations within the bag chambers can have the same or different consistency and are preferably of a liquid consistency, for example liquid, gel-like, pasty, wax-like, or of a solid consistency, for example powdery, granular-like, free-flowing or solid-like. The term “detergent preparation” is to be understood broadly within the meaning of the invention.

Such detergent products with multiple bag chambers are, for example, from EP 3 381 835 A1 known. The detergent products described therein have a high intrinsic dimensional stability and thereby enable improved use in particular in textile washing machines, which includes in particular improved dissolution behavior during the washing process, ie a high dissolution rate and largely residue-free dissolution. In addition, these detergent products can be easily manufactured in a cost-effective and resource-saving manner with good machine usability and meet the high demands of users when it comes to innovative product design.

It is particularly important for consumers that the number of chambers is easy to recognize. Manufacturers therefore currently use compositions, especially liquid detergent preparations, in the various chambers that can be easily distinguished from each other by strong color differences or contrasts. In particular, designs in which a chamber is filled with a white, opaque preparation perform well in consumer surveys.

However, it has been shown that the opacifiers used here are potentially disadvantageous from an environmental protection point of view, particularly in view of the microplastic particles under discussion.

In the registration US 2009/0196891 A1 Water-soluble bags are described which comprise a multi-phase detergent. The patent US 8,835,372 B2 discloses water-soluble multi-chamber liquid detergent pouches containing opacifying agents.

Proceeding from this, the invention is based on the object of providing a detergent product which dispenses with the corresponding compounds without impairing user acceptance and the overall impression of the product.

It has now surprisingly been found that a multi-chamber detergent product with a central chamber that is filled with a transparent and achromatic preparation and therefore itself appears transparent and colorless, still shows a high contrast and the product design continues to be very appealing to users.

In a first aspect, the invention therefore relates to a detergent product (1), in particular for textile treatment, more particularly for textile cleaning and/or for textile laundry, with a film bag (2) having a plurality of bag chambers (3), each of which has at least one water-soluble film are enclosed, the bag chambers (3) being formed by water-soluble films connected to one another in a sealing plane and separated from each other by sealing sections (4) lying in the sealing plane, and the bag chambers (3) each being filled with a detergent preparation, a plurality of bag chambers (3) with the number n ≥ 2 is provided, the bag chambers (3) being arranged in at least one cutting plane around a common n-fold axis of rotation perpendicular to the cutting plane and at least one arranged in the central region of the film bag (2). Central chamber (12) is provided, which is filled with a detergent preparation, and the bag chambers (3) are arranged around the central chamber (12),
characterized in that
the detergent preparation with which the central chamber is filled is transparent and achromatic and the detergent preparations with which the bag chambers (3) are filled are colored.

The detergent preparation in the central chamber and preferably also the preparations in one or more, preferably all, bag chambers are liquid, i.e. flowable under standard conditions (20 ° C, 1013 mbar). However, "liquid" as used herein also includes highly viscous liquids, liquids with yield points and gels.

In various embodiments, the detergent preparation with which the central chamber (12) is filled has a turbidity of <50 NTU, preferably <30 NTU, even more preferably <20 NTU, most preferably <10 NTU or <5 NTU. The Nephelometric Turbitity Unit (NTU) is a unit of turbidity of liquids that can be measured with a calibrated nephelometer. The light scattering is measured at an angle of 90° to the incident light (white light) according to EPA Procedure 180.1 (United States Environmental Protection Agency, Revision 2.0, August 1993). Alternatively, the turbidity can also be specified in the unit FNU, which is analogous to NTU. This is determined according to ISO 7027 under 90° scattered light at a wavelength of 860 nm. The turbidity measurements are preferably determined using a laboratory turbidity meter model 2100N from Hach (Hach, USA), which measures according to USEPA method 180.1, in a 30 mL glass cuvette (Hach, DE). Alternatively, the same device can be used that measures according to ISO 7027. Unless otherwise stated, the turbidity values stated herein are those determined using the instrument cited in accordance with the USEPA 180.1 method. "Transparent", as used herein, therefore means in particular that the preparation meets the turbidity values specified above.

In various embodiments, the detergent preparation with which the central chamber (12) is filled is free of enzymes, opacifying agents and/or fragrances. It is particularly preferred that they are free of opacifying agents, whereas, in various embodiments, enzymes and fragrances may be included. However, it can also be preferred that no enzymes and/or fragrances are included. “Free from” as used in this context means that the corresponding ingredient is present in the composition in an amount <1% by weight, preferably <0.1% by weight, more preferably <0.01% by weight. In particular, such a component is not added intentionally. These components are not included in particular because they can adversely affect the clouding and thus the appearance of the formulation.

In various embodiments, the detergent preparation with which the central chamber (12) is filled contains at least one optical brightener, preferably an optical brightener of the stilbene type, preferably in an amount <1% by weight based on the total weight of the detergent preparation in the central chamber , more preferably <0.6% by weight. Stilbene-type brighteners for use in detergents are known in the art and include, in particular, triazinyl derivatives of 4,4'-diamino-2,2'-stilbenesulfonic acid. The most economically important stilbene derivatives are DAS1 (disodium 4,4-bis[(4-anilino-6-morpholino-1,3,5-triazin-2-yl)amino]-stilbene-2,2-disulfonate) and DSBP ( disodium 4,4-bis(2-sulfostyryl)biphenyl). Such compounds are commercially available, for example, under the trade name Tinopal, such as Tinopal CBS-X (BASF).

Alternatively or additionally, the detergent preparation with which the central chamber (12) is filled can comprise at least one blue or violet dye in small amounts - for example a so-called shading dye. This is in an amount >0% by weight, but preferably in an amount <0.1% by weight, based on the total weight of the detergent preparation in the central chamber, more preferably <0.02% by weight, for example between 0.001 and 0.01 % by weight included. The quantities are based on the total weight of the preparation in the central chamber. Such a dye serves, for example, the purpose of covering up any possible yellowish tint to the preparation. This dye, if used, does not change the fact that the preparation appears largely colorless when viewed with the naked eye. A suitable dye is, for example, commercially available under the name Milliken Liquitin Violet 129.

In various embodiments, the detergent preparation with which the central chamber (12) is filled contains at least one antioxidant or color stabilizer. This is in an amount >0% by weight, but preferably in an amount <0.5% by weight, based on the total weight of the detergent preparation in the central chamber, more preferably <0.3% by weight, for example between 0.05 and 0 .15% by weight. The quantities are based on the total weight of the preparation in the central chamber. For example, but not limited to, metabisulfites (pyrosulfites), in particular sodium metabisulfite (Na ₂ S ₂ O ₅ ), are suitable.

The detergent preparation in the central chamber is colorless or achromatic. This means in particular that it does not have a yellowish color. This preferably means that the Hazen color index is below a value of 310, particularly preferably below 290, even more preferably below 280, most preferably below 260. For formulations without optical brighteners, the Hazen color index is preferably generally below 250, particularly preferably below 230, even more preferably below 200, most preferably below 180. The Hazen color index can be defined as color value). become. The instrument used for this purpose is a Hach Lange Lico 500 spectrocolorimeter with reference beam technology (Hach, DE) with Hach Lange LZM 130 cuvettes (1 cm, disposable cuvettes), which has been calibrated with deionized water (as a reference) and with certified test solutions (Addista Color). . The instrument measures the XYZ transmission and automatically calculates the Hazen color values. Unless otherwise stated, the Hazen values mentioned herein are those that were determined using the device mentioned in accordance with the DIN EN 1557:1996 method within 72 hours of formulation of the preparation and, if necessary, storage at room temperature. With prolonged storage, for example over a period of 12 weeks or longer, the Hazen Color Index may increase. When stored for 12 weeks at room temperature, the Hazen Color Index according to the invention is preferably below a value of 450, particularly preferably below 400, even more preferably below 350.

Additionally or alternatively, the feature achromatic can mean that the preparation without shading/tinting dye has an absorption <0.10, preferably <0, when measuring a VIS spectrum (undiluted) in the range 400-800 nm, in the wavelength range >450 to 800 nm .08, more preferably <0.06 or <0.05. With shading/tinting dye, the preparation has an absorption <0.20, preferably <0.17, <0.15, < when measuring a VIS spectrum (undiluted) in the range 400-800 nm, in the wavelength range >450 to 800 nm 0.12 or <0.10, preferably <0.08, even more preferably <0.06 or <0.05. These measurements can also be carried out in accordance with DIN EN 1557:1996 with a Hach Lange Lico 500 spectral colorimeter with reference beam technology (Hach, DE) with Hach Lange LZM 130 cuvettes (1 cm, disposable cuvettes), which are filled with deionized water (as a reference) and with certified Test solutions (Addista Color) were calibrated. Unless otherwise stated, the absorption values mentioned herein are those that were determined using the device mentioned in accordance with the DIN EN 1557:1996 method.

The absorption of the detergent preparation of the central chamber is, in various embodiments, equal to or lower than the absorption of the preparations in the bag chambers over the entire visible light range. This ensures that there is sufficient contrast between the different chambers.

Further components of the detergent preparation of the central chamber include, but are not limited to, organic solvents, such as glycerin and/or 1,2-propanediol, anionic and/or nonionic surfactants, such as linear alkylbenzene sulfonates and fatty alcohol ethoxylates, soaps, alkali formers, bitter substances, Complexing agents such as phosphonates, soil-removing polymers such as (modified) polyethyleneimines and polyesters made from propylene glycol and terephthalates. The latter are commercially available, for example, under the trade names ^Sokalan® (BASF) and ^Texcare® (Clariant).

In general, the detergent preparations in the central chamber are preferably highly concentrated formulations with surfactant contents >35% by weight, for example up to 75% by weight, typically in Range 40 to 65% by weight, based on the total weight of the preparation. The surfactants can be selected, for example, from anionic, cationic, nonionic, amphoteric and zwitterionic surfactants and soaps. The surfactants are/comprise preferably combinations of anionic and nonionic surfactants, for example 25 to 40% by weight, preferably 26 to 35% by weight, of anionic surfactants and 15 to 30% by weight, preferably 18 to 28% by weight, Niotensides, each based on the total weight of the preparation. In addition (to the anionic and nonionic surfactants), the preparation can contain soaps which are not considered anionic surfactants in the sense of the above disclosure and can be contained in amounts of 1 to 15% by weight, based on the total weight of the preparation. Preferred anionic surfactants are linear alkylbenzene sulfonates, for example C9-13 alkylbenzene sulfonates, and fatty alcohol ether sulfates, in particular linear alkylbenzene sulfonates. Suitable nonionic surfactants are alkoxylated, in particular ethoxylated, fatty alcohols and oxo alcohols, for example with 3 to 8 EO. Combinations of linear alkylbenzene sulfonates and alkoxylated fatty alcohols/oxo alcohols are generally preferred.

The detergent preparation of the central chamber is in particular low in water to anhydrous, i.e. the water content, based on the total weight, is typically less than 18% by weight, usually up to 15% by weight, for example up to 13% by weight. The lower limit can be, for example, 0, 1, 2, 3 or 4% by weight.

The detergent preparations with which the bag chambers (3) are filled are colored. This makes them different from preparation in the central chamber. The preparations in the different bag compartments can have the same color, but are preferably colored differently. “Colored,” as used in this context, means that the preparations appear colored to the naked eye to the user. “Differently colored” means that the individual preparations have different colors that can be seen by the consumer with the naked eye. Examples of such colors include, without limitation, green, light blue, dark blue, turquoise, and violet.

After adding the detergent products described herein to water, the film dissolves and releases the detergent preparation. The film bag can be formed from several water-soluble films, the water-soluble film preferably being PVA film (polyvinyl alcohol film). The films that can be used usually consist of polyvinyl alcohol copolymers with appropriate additives such as plasticizers, water, surfactants, antioxidants, lubricants, release agents, bitter substances or salts. The film bag can be made from a water-soluble base film and a water-soluble cover film, which form the boundary walls of at least one bag chamber. The base film can be deep-drawn, for example in a plastically deforming manner, to form at least one bag chamber. The base film and the cover film are then placed in one or more sealing or Connecting sections sealed or connected to each other. The sealing sections then lie in a so-called sealing plane or connecting plane of the two films.

In the detergent products, a plurality of bag chambers with the number n ≥ 2 or n ≥ 3 are provided, the bag chambers being arranged in at least one cutting plane around a common n-fold axis of rotation perpendicular to the cutting plane. By rotating the foil bag or the detergent product through an angle of 360°/n around the axis of rotation, the arrangement of the bag chambers can be brought back into line with itself, based on the surfaces of the bag chambers in the cutting plane. If the foil bag or the detergent product rotates around the axis of rotation and the arrangement of the bag chambers remains essentially indistinguishable from the initial state when rotating through 360 ° / n, then the foil bag has an n-fold axis of rotation in the sense of the present invention. In the case of, for example, a three-fold axis of rotation, a rotation of the film bag through an angle of 120° around the axis of rotation leads to the cutting surfaces of the bag chambers being brought into line with themselves again in the cutting plane. This creates a total of three symmetry-equivalent or essentially congruent arrangements of the bag chambers, based on the cutting surfaces of the bag chambers in the cutting plane.

The term “detergent product” is to be understood broadly within the meaning of the invention and in particular also includes those products that are used for cleaning dishes in dishwashers. The term “detergent preparation” is therefore also to be understood broadly and also includes, for example, machine dishwashing detergents and rinse aids. The following statements relating to the use of the detergent product according to the invention in textile washing machines also apply accordingly to embodiments of the detergent product according to the invention for use in dishwashers, without going into detail.

The bag chambers can be designed in a flow-optimized manner and arranged relative to one another in a flow-optimized manner, which when used in a textile washing machine leads to a uniform and intensive flow around and over the bag chambers combined with a rapid and largely complete dissolution of the film material. The bag chambers can in particular be designed in such a way that fewer areas of attack are created for laundry items, such as buttons and/or applications. Accordingly, the detergent products according to the invention are less likely to get caught on laundry items and are therefore moved more intensively during a washing process, so that a sufficiently high level of water contact is ensured during the washing process.

Finally, configurations of the bag chambers and their arrangement relative to one another are possible, which are characterized by a very compact structure. The compact structure leads to reduced material consumption. Manufacturing and packaging processes are simplified.

The product design, i.e. the geometric design of the bag chambers, their size and their arrangement relative to one another, can also provide very narrow sealing sections between adjacent chambers, which leads to a reduction in the dimensions of the detergent product according to the invention and thus maximum utilization of the apparatus and machine capacities for production and the transport of the detergent products and equipment and machines used. In addition, the external appearance of the detergent products is enhanced.

The bag chamber can be formed by at least two, preferably only two, layers of film sealed together in one or more sealing sections. Preferably, only adjacent and separate bag chambers are provided and no superimposed/overlapping bag chambers, so that the production of the film bag is possible using only two layers of film. This leads to reduced manufacturing costs and reduced manufacturing effort. The film bag can be made from a water-soluble base film and a water-soluble cover film, which are tightly connected to one another in the sealing plane. The base film can be deep-drawn in a plastically deforming manner to form bag chambers.

The bag chambers are separated from each other by sealing sections located in the sealing plane. The sealing sections can in particular be designed to run non-rectilinearly and thus ensure a desired high intrinsic dimensional stability of the detergent product.

The outer contour of the foil bag in the sealing plane can preferably be circular, triangular or square. The shaping can be done, for example, by laser cutting or punching. Other outer contours of the foil bag are not excluded.

In a particularly preferred embodiment, the bag chambers in the sealing plane have the same base surfaces, which are arranged around a common n-fold axis of rotation perpendicular to the sealing plane, where n is the number of bag chambers. When producing the bag chambers by plastically deforming a base film in a deep-drawing tool and subsequently connecting it to a cover film, the shape and size of the base surfaces are determined by the contours of the chamber cavities of the deep-drawing tool. “Same” in the sense of the invention includes an identical shape and size of the base surfaces or an approximately identical shape and size of the base surfaces, ie a substantially identical shape and size, so that when the film bag rotates n times around the axis of rotation in Essentially symmetry-equivalent appearances of the base surfaces in the sealing plane result. "Essentially symmetry-equivalent appearances of the base surfaces" are present in the sense of the invention in particular when the degree of surface coverage of the base surfaces of the bag chambers after a rotation of the film bag starting from a 0 ° position in Initial state by 360 ° / n, ie, for example, with a three-fold axis of rotation, a rotation of the film bag by 120 °, at least 90%, preferably at least 95%, in each case with reference to the initial state.

The foil bag can have between two and ten or between three and ten bag chambers, preferably between three and five bag chambers, which can have the same or different detergent preparations. Accordingly, the bag chambers can be arranged around a three- to nine-fold axis of rotation, preferably around a three-, four- or five-fold axis of rotation. Despite the high number of chambers, a compact and flow-optimized design with the advantages mentioned above is possible due to the arrangement of the bag chambers around an n-fold axis of rotation.

In particular, in the case of a film bag with a circular or polygonal, for example square or triangular, outer contour of the film bag in the sealing plane, a centrally arranged n-fold axis of rotation can be provided, around which the bag chambers are arranged. This allows for a very compact structure of the detergent product according to the invention. Furthermore, a product design that is very appealing from the user's point of view can be achieved with sealing sections that are as small as possible. Consumer acceptance of the use of the detergent products according to the invention is correspondingly high.

Although not necessarily provided, preferably at least two bag chambers, preferably all bag chambers, have the same filling volume and/or the same spatial shape. The term “same” includes an identical filling volume and/or an identical spatial shape or also an approximately identical filling volume and/or an approximately identical spatial shape, which means a deviation in the filling volume of less than 20%, preferably of less than 10%, more preferably of less than 5%, and/or a non-identical, but essentially identical appearance of the bag chambers from the user's point of view when viewed spatially. With the same design of the bag chambers, a high intrinsic stability of the film bag can be ensured and an intensive and uniform flow around all bag chambers can be achieved, so that they dissolve essentially at the same speed. In addition, in three-dimensional space, fewer attack surfaces are created on which laundry items, such as buttons or applications, can get caught and then unintentionally transport the foil bag. Finally, the formation of bag chambers of equal size simplifies the production of the detergent product according to the invention and reduces the manufacturing costs. The filling volume of the bag chambers can be in the range between 1 ml and 50 ml, preferably in the range between 2 ml and 15 ml.

It is also expedient if the base surface of the bag chamber lying in the sealing plane is axially asymmetrical. The base surface is axially asymmetrical if it does not pass through one vertical axis reflection can be imaged onto itself on a mirror axis running through the base surface. The axial asymmetry allows flow conditions to be achieved in the bag chamber, which lead to improved and more uniform dissolution of the film material when the detergent product is used in a washing process. A specific arrangement of the bag chambers relative to one another also makes it possible to achieve a compact structure of the film bag, whereby the width of the sealing sections between adjacent bag chambers can be reduced. A modern product design with unusual bag chamber shapes is possible, which draws the user's attention more closely to the bag chambers and their contents. This contributes to high consumer acceptance of the detergent product according to the invention. Against this background, a preferred embodiment of the invention provides teardrop-shaped, leaf-shaped or yin and yang-shaped base surfaces of the bag chamber. A particularly preferred contour of the bag chamber in the sealing plane is characterized by a narrow convex end section and a wide convex end section of the contour opposite in the longitudinal direction of the bag chamber. The contour can be characterized by a first circular shape with a smaller inner radius placed on the narrow end section and a second circular shape with a larger inner radius placed on the wider end section, the ratio of the larger inner radius to the smaller inner radius being more than 3:1, preferably more than 5 :1, more preferably more than 8:1, or can be more than 12:1. When producing the film bag in a deep-drawing mold, the inner radii are determined by the cavities of the deep-drawing mold. Between the narrow convex end section and the wide convex end section, the contour can be provided by a concave or straight inner section directed towards the center of the foil bag and a convex or straight outer section directed towards the outer edge of the foil bag, resulting in a teardrop-shaped, leaf-shaped or yin and yang-shaped Base area of the bag chamber can result.

An advantageous embodiment of the bag chamber contour in the sealing plane can provide that a wide convex end section of the contour of a first bag chamber adjoins or lies opposite a concave or straight inner section and/or a narrow convex end section of the contour of an adjacent second bag chamber. Alternatively or additionally, the narrow convex end section of the contour of the second bag chamber can also partially encompass the wide convex end section of the contour of the adjacent first bag chamber from the outside. Alternatively or additionally, the wide convex end portion of the contour of the first bag chamber may intersect a tangent placed on the wide convex end portion and on the narrow convex end portion of the contour of the adjacent second bag chamber. The wide convex end section of the first bag chamber then extends into a concave area of the contour of the second bag chamber. The contours described above allow for a product design that is characterized by a very compact arrangement of the bag chambers on the foil bag.

In particular, the transitions of the bag chambers in the circumferential direction of the film bag can be characterized by narrow sealing sections. The sealing sections can have a maximum width of less than 5 mm, preferably less than 3 mm, more preferably only 2 mm or less, particularly in the radially outer areas between two adjacent bag chambers. The detergent product is therefore less likely to get caught on laundry items. This results in intensive contact of the foil bag with the washing solution, the laundry drum and the laundry during a washing process and riding on the load of laundry is prevented, which results in improved dissolution behavior of the foil bag. Furthermore, a higher intrinsic stability of the detergent product can be achieved in this way. From the user's perspective, the product design can be made modern and interesting due to the unusual shape of the bag chambers, whereby the user is only slightly aware of narrow sealing sections between the bag chambers and the user's attention is drawn to the bag chamber and its contents.

In order to achieve the most homogeneous flow possible to the bag chambers and good dissolution behavior as well as high intrinsic dimensional stability with the narrowest possible sealing sections between the bag chambers, the outer sections of the contours of the bag chambers in the sealing plane can at least essentially lie on a common circumferential line, which is essentially circular , elliptical, superelliptical, square, rectangular or triangular shape.

It has been shown that particularly advantageous flow conditions in the bag chambers and an overall very good dissolution behavior of the film bag can be achieved if a bisector of the base surface of a bag chamber in the sealing plane is left- or right-handed and, preferably, a left- or right-handed arrangement all bag chambers are provided. The base surfaces of all bag chambers can have outer contours and/or inner contours with at least sections of the same direction of curvature. The bisectors of all the bag chambers of the film bag are then bent in the same direction, i.e. either to the left or to the right, which leads to an aesthetically pleasing appearance of the detergent product according to the invention. Furthermore, a curvature of the bag chambers in the same direction can help ensure that the detergent product comes into intensive contact with the laundry solution and the items of laundry in the washing drum and that the laundry solution "travels" to a certain extent without getting stuck on certain items of laundry and without riding up on the load of laundry or even getting stuck Porthole to be promoted.

Particularly advantageous for improved dissolution behavior is a shape of the base surface of the bag chamber lying in the sealing plane, in which the width of the base surface transversely to the bisector of the surface, starting from a narrow convex end section of the contour of the bag chamber in the sealing plane, initially along the bisector of the surface in the direction of one opposite wide convex end section of the contour increases steadily until a maximum value of the width is reached. The width can then decrease again up to the wide convex end section. Accordingly, the cross-sectional area of the bag chamber perpendicular to the sealing plane can increase steadily along the bisector of the surface, starting from the narrow convex end section of the contour, until a maximum value is reached, and then decrease again until the wide convex end section is reached. The bag chamber can then have a helical structure both in two-dimensional space in the sealing plane and in three-dimensional space in the direction of rotation or rotation of the surface bisector. Here, the cross-sectional area of the bag chamber can initially increase over a longer section of the area bisector until the maximum value is reached and then decrease again over a shorter section after reaching the maximum value. The same can apply to the width of the base area.

The subsequent bag chamber can then be connected with the same cross-sectional profile, whereby the maximum cross-sectional area of a subsequent bag chamber can be equal to the maximum cross-sectional area of a previous bag chamber or larger or smaller than the maximum cross-sectional area of a previous bag chamber. If the contour of the bag chamber in the sealing plane has a narrow convex end section and a wide convex end section opposite the narrow convex end section, the maximum cross section or the maximum width of the bag chamber can be in the area of the center of a circular arc placed from the inside on the wide convex end section lay.

At least one central chamber is provided in the central region of the film bag, with the bag chambers being arranged around the central chamber. This optimizes the dissolution behavior of the detergent product and achieves a high level of stability against unintentional folding of the bag chambers when holding the detergent product.

The central chamber is separated from each bag chamber by a sealing section, whereby the central chamber can be an equal distance from each bag chamber. The minimum width of the sealing section between a bag chamber and the central chamber may be less than 5 mm, preferably less than 3 mm, more preferably less than 2 mm. This enables high intrinsic dimensional stability and a product design that is appealing from the user's perspective.

The central chamber has a base area in the sealing plane, whereby the base area can be circularly symmetrical or n-fold rotationally symmetrical, with n being the number of bag chambers of the film bag. For example, the central chamber can have a circular base surface or a polygon-shaped base surface, preferably a square, triangular, star-shaped, propeller-shaped or fan wheel-shaped base surface. In the sealing plane, the central chamber can, for example, have a triangular base surface with convexly curved corner sections and have convex and/or concave and/or wavy side sections. In three-dimensional space, the central chamber can be hemispherical, for example. Through a rotationally symmetrical design of the central chamber in two-dimensional space, that is, based on a top view of the base surface of the central chamber in the sealing plane, and/or in three-dimensional space, that is, based on a perspective view of the central chamber, the basic idea according to the invention of arranging the bag chambers around one n-fold axis of rotation is taken into account and this basic idea is further developed to reinforce the advantages described above. The central chamber is therefore designed differently and therefore has a different spatial shape than the other bag chambers surrounding it.

The manufacturing process of the detergent product according to the invention and also the water-soluble films used to produce the product are fundamentally known to those skilled in the art and are also described in the EP 3 381 835 A1 described. Examples of preferred polymers, copolymers or derivatives suitable for use as a bag compartment, as well as suitable detergent preparations, are also in the DE 10 2014 102 567 A1 described.

The figures show different embodiments of detergent products 1 for textile treatment in the format of disposable portion packs. Such a portion pack is used for a one-time textile treatment application, usually in a textile washing machine. Each detergent product 1 has a foil bag 2 with two or three bag chambers 3. The individual bag chambers 3 contain detergent preparations which can contain detergent-active substances for textile treatment, in particular textile laundry. Water-soluble PVA films with the type designation M8630 or M8720 from the film manufacturer Monosol can be used to produce the film bag 2. Alternatively, appropriately designed water-soluble films from other film manufacturers, such as Aicello, Nippon Gohsei or Mondi, can also be used.

The film bag 2 is formed from two water-soluble films, which can be designed as PVA films. The water-soluble films enclose the bag chambers 3 by forming their boundary walls. The films are connected to one another in the area of sealing sections 4 in such a way that the bag chambers 3 are each completely closed by the sealing sections 4 and separated from one another. A sealed film section is also provided between two adjacent bag chambers 3, which connects the bag chambers 3 to one another to achieve a single portion pack.

The bag chambers 3 each have the same base area A1 in the sealing plane or the connecting plane between the films ( Figures 2, 3 ; 9, 10 ; 16, 17 ), while the entire detergent product 1 or the foil bag 2 has the base area A2 in the sealing plane. The base area A1 of a bag chamber 3 is limited by the contour line of the respective bag chamber 2 in the sealing plane. The base area A2 of the (entire) detergent product 1 is limited by its contour line of the sealing plane. With those in the Figures 1 to 21 In the embodiments shown, a substantially circular or superelliptical base surface A2 of the detergent product 1 is provided, whereas in the embodiments shown in FIG Figures 22-24 In the embodiments shown, a substantially square base area of the detergent product is provided.

With those in the Figures 1-21 In the embodiments shown, the base surfaces A1 of the bag chambers 2 each have a teardrop or teardrop shape with a narrow convex end section 5 of the contour line of the respective bag chamber 3 in the sealing plane (with a smaller inner radius r1) and with a wider convex end section 6 opposite in the longitudinal direction of the bag chamber 3 (with a larger inner radius r2). Between the two convex sections 5, 6 at the ends of the bag chamber 3, a concave or possibly straight connecting section 7 is provided radially on the inside and a convex or straight connecting section 8 is provided radially on the outside.

The different product designs in the are presented below Figures 1 to 21 Detergent products 1 shown, ie in particular the geometric configuration (shape), the size and the arrangement of the bag chambers 3 relative to one another, are explained in detail. All of the embodiments shown in these figures have the common feature that a plurality of bag chambers 3 with the number n ≥ 3 are provided, with the bag chambers 3 in at least one cutting plane, in this case the sealing plane, around a common n-number standing perpendicular to the cutting plane Rotary axis Y ( Figures 1 , 8th , 15 ) are arranged. This provides a compact arrangement of the bag chambers 3 with narrow sealing sections 4 between the bag chambers 3, so that product capacities of the apparatus and systems used to produce the detergent product 1 can be optimally utilized.

The compact arrangement of the bag chambers 3 also reduces the attack surfaces on which laundry items, such as buttons or applications, can get caught. If a snag occurs, the detergent product 1 can be held on the corresponding item of laundry and transported with it, so that overall the circulation movements of the detergent product 1 decrease during a washing process in a textile washing machine and the foil bag 2 is washed around less intensively with the washing liquid. The limited movement of the detergent product 1 and the lower rinsing deteriorate the dissolution behavior of the water-soluble film bag 2, namely the dissolution rate and the degree of dissolution achieved during a washing process.

In addition, the compact arrangement of the bag chambers 3 leads to a higher intrinsic stability of the film bag 2, which increases the user's acceptance of the detergent products 1.

An improved dissolution behavior of the film bag 3 also results from a flow-optimized design of the bag chambers 3 and from a flow-optimized arrangement of the bag chambers 3 relative to one another. In the embodiments shown, the bag chambers 3 are flowed around turbulently during a washing process, so that in particular the sealing sections 4 of the film bag lying between adjacent bag chambers 3 dissolve in a shorter time and more completely than is the case with the detergent products 1 known from the prior art . The transitions of the bag chambers 3 in the (radially) outer edge regions of the film bag 2 are characterized by narrow sealing sections between adjacent bag chambers 3, so that the user's eye is directed to the bag chambers 3 and their contents. The result is a very appealing, “innovative” product design, which contributes to a high level of user acceptance.

The ones in the Figures 1 to 21 Detergent products 1 shown each have three bag chambers 3 with the same base surfaces A1 in the sealing plane, the base surfaces A1 being arranged around a common 3-fold axis of rotation Y perpendicular to the sealing plane. If the film bag 2 or the detergent product 1 rotates about the axis of rotation Y, the arrangement of the bag chambers 3 remains essentially indistinguishable from the initial state when rotated by 120 °, with a total of three symmetry-equivalent or essentially congruent arrangements of the base surfaces A1 being created.

In the embodiments shown in the figures, the bag chambers 3 are arranged around a central chamber 12 in the central region of the film bag 2. The bag chambers 3 are arranged one behind the other in the longitudinal direction of the bag chambers 3 or in the circumferential direction of the base surface A2 of the film bag 2 and do not overlap one another. All bag chambers 3 have the same filling volume and the same spatial shape. The central chamber 12 is surrounded by the bag chambers 3. When used, the central chamber 12 leads in one Textile washing machine causes strong turbulence of the washing water in the middle area of the foil bag 2 between the adjacent bag chambers 3. The central chamber 12 allows the dissolution behavior of the foil bag 2 to be further optimized. Basically, the central chamber 12 has a different design than the bag chambers 3 surrounding it, both with its base area A3 and with its entire spatial shape.

It is also the case that the base surface A1 is axially asymmetrical. The base surface A1 can each be designed in the shape of a drop. Based on a circular shape with a smaller inner radius r1 placed on the narrow convex end section 5 of the contour of the bag chamber 3 in the sealing plane and a circular shape with a larger inner radius r2 placed on the wider convex end section 6, the ratio of the larger inner radius r2 to the smaller inner radius r1 is as follows Fig. 2 at about 5:1 or more.

How further unfolds Fig. 2 results, adjacent bag chambers 3 are arranged relative to one another in such a way that the wider convex end section 6 of the contour of a first bag chamber 3 lies opposite the concave connecting section 7 of a second bag chamber 3 following in the circumferential direction. The narrower convex end section 5 of the subsequent second bag chamber 3 is offset radially outwards relative to the wider convex end section 6 of the first bag chamber 3 with respect to the surface bisector 10 of the two base surfaces A1 of the adjacent bag chambers 3. Here, the starting point of the surface bisector 10 of the base surface A1 at the narrow end of a bag chamber 3 following in the circumferential direction of the film bag 2 is offset radially outwards compared to the end point of the surface bisector 10 of the base surface A1 at the wide end of a preceding bag chamber 3.

The wider convex end section 6 of the contour of a preceding bag chamber 3 in the sealing plane also intersects a tangent 9, which is placed on the narrow convex end section 5 and on the wide convex end section 6 of the contour of a subsequent bag chamber 3 and thus extends into a concave area the subsequent bag chamber 3.

The connecting sections 7, 8 of the contours of all bag chambers 3 in the sealing plane have the same direction of curvature starting from the narrow convex end section 5 to the wide convex end section 6 of the respective bag chamber 3. The same applies to the bisector 10. According to Fig. 2 This results in a left-handed arrangement of the base surfaces A1 of the bag chambers 3 in a plan view in the direction from the narrow convex end section 5 to the wide convex end section 6 (or a corresponding right-handed arrangement in a view from below of the foil bag 2 according to Fig. 3 ). It goes without saying that, in a top view, a clockwise arrangement of the base surfaces A1 of the bag chambers 3 can also be provided.

Further follows from Figure 2 that the width b of the base surface A1 of each bag chamber 3 transversely to the bisector 10, starting from the narrow convex end section 5 towards the wide convex end section 6, initially increases steadily until a maximum width is reached. The width then decreases steadily until it reaches the wide, convex end section 6. The same applies to the cross-sectional area perpendicular to the sealing plane. Here, the cross-sectional area increases, starting from a narrow end of the bag chamber 3 (cross-sectional area = 0) towards a wide end of the bag chamber 3 (cross-sectional area = 0) in the longitudinal direction of the bag chamber 3, initially over a greater length with a smaller gradient, until a maximum cross-sectional area the bag chamber 3 is reached and, after reaching the maximum cross-sectional area, drops back to zero at the wider end of the bag chamber 3 over a shorter length with a steeper gradient. This is then followed by the subsequent bag chamber 3 with an identical or similar cross-sectional profile, with the maximum cross-sectional area of the subsequent bag chamber 3 in the Figures 1 to 21 shown embodiments is each equal to the maximum cross-sectional area of a previous bag chamber 3.

The geometry of the bag chamber 3 or its envelope is therefore both in two-dimensional space in the sealing plane (in a top view of the base surfaces A1) and in three-dimensional space (in a perspective view of the bag chambers 3) in the direction of curvature of the surface bisector 10 by a helical structure marked.

The maximum width of a base area A1 or the maximum cross-sectional area of a bag chamber 3 can be achieved in the area of the center of a circular arc placed from the inside on the wide convex end section 6 of the contour line of the bag chamber 3 in the sealing plane.

It should also be noted that the convex outer connecting sections 8 of the contour lines of the bag chambers 3 of a film bag 2 in the Figures 1 to 21 detergent products 1 shown are arranged on a common at least substantially circular or superelliptical circumferential line 11. Other shapes of the circumferential line 11 are not excluded, for example the circumferential line 11 can be rectangular or square. This also contributes to a compact structure. The smallest distance between two bag chambers 2 following in the direction of the circumferential line 11 in the sealing plane can preferably be less than 5 mm, more preferably less than 3 mm, particularly preferably less than 2 mm. Due to the deformations that occur during the production of the film bag 2 by deep drawing and due to restoring forces of the film layers, adjacent bag chambers 3 can even partially rest against each other when the detergent product 1 is in use.

At the in the Figures 1 to 7 In the embodiment shown, a spherical central chamber 12 with a circular base surface A3 is provided in the sealing plane ( Fig. 2 ).

The ones in the Figures 8 to 14 The embodiment shown shows a central chamber 12, which forms a dome on the top and bottom of the foil bag 2 with a triangular base surface A3 in the sealing plane. The base surface A3 is characterized by more convexly curved corner sections 13 and only slightly convexly curved side sections 14. In comparison to that in the Figures 1 to 7 In the embodiments shown with a central chamber 12, which has a circular base area A3 in the sealing plane, the surface area of the sealing sections 4 between the central chamber 12 and the adjacent bag chambers 3 can be reduced to a greater extent by means of a central chamber 12 with a triangular base area A3. The user perceives the sealing sections 4 between the central chamber 12 and the bag chambers 3 less strongly, which contributes to an appealing aesthetic appearance of the detergent product 1 and draws the user's interest even more towards the bag chambers 3 and the detergent preparations contained therein.

The ones in the Figures 15 to 21 The embodiment shown has a central chamber 12 with a base surface A3, the contour of which is even more closely adapted to the contour of the adjacent bag chambers 3. This leads to a substantial minimization of the size of the sealing surfaces in the central region of the film bag 2 between the bag chambers 3. The base surface A3 of the central chamber 12 has approximately the shape of a distorted triangle with convex corner sections 13 and S-shaped or wave-shaped side sections 14 in between. Over the course of the side sections 14, the minimum distance between the base surface A3 of the central chamber 12 and the base surfaces A1 of the adjacent bag chambers 3 remains essentially constant.

The base surfaces A3 of the central chambers 12 are in the Figures 8 to 21 Embodiments shown are each designed or arranged three-fold rotationally symmetrical.

The ones in the Figures 22-24 Detergent products 1 shown each have two bag chambers 3 with the same base surfaces in the sealing plane.

Production of a four-chamber portion bag with the film Kuraray Monosol M8720, 88 µm film thickness in a four-chamber cavity (deep-drawing temperature 102 °C, sealing temperature 150 °C). 7.5 g of formulations 1 to 3 were prepared in one chamber 1 to 3 and 2.5 g of formulation 4 (Table 1: universal detergent; Table 2: color detergent) in the central chamber. Total weight of liquids: 25g. For both formulations 4, NTU, Hazen and absorbance in the range 450-800 nm were determined using the methods given above.

NTU: Light scattering was measured at an angle of 90° to the incident light (white light) in accordance with EPA Procedure 180.1 (United States Environmental Protection Agency, Revision 2.0, August 1993) using a model 2100N laboratory turbidity meter from Hach (Hach, USA) in a 30 mL glass cuvette (Hach, DE).

Hazen: The Hazen color index was determined in accordance with DIN EN 1557:1996 (surface-active substances - colorimetric characterization of optically clear, colored liquids (products) as X, Y, Z transmission color values) with a Hach Lange Lico 500 spectral colorimeter with reference beam technology (Hach, DE) and Hach Lange LZM 130 cuvettes (1 cm, disposable cuvettes), which were calibrated with deionized water (as a reference) and with certified test solutions (Addista Color). The samples were previously stored at room temperature for 3 weeks.

Absorption: According to DIN EN 1557:1996 with a Hach Lange Lico 500 spectral colorimeter with reference beam technology (Hach, DE) with Hach Lange LZM 130 cuvettes (1 cm, disposable cuvettes), which is filled with deionized water (as a reference) and with certified test solutions (Addista Color ) was calibrated.

   (ii) the film bag (2) has between 2 and ten bag chambers (3), preferably between 3 and 5 bag chambers (3); and/or

   (iii) the bag chambers (3) are arranged in at least one sectional plane about a 3- to 9-fold axis of rotation, preferably about a 3- or 4- or 5-fold axis of rotation; and/or

   (iv) the bag chambers (3) are arranged in at least one sectional plane about a centrally arranged n-fold axis of rotation;

   (v) at least two bag chambers (3), preferably all bag chambers (3), have an identical filling volume and/or an identical spatial shape; and/or

   (vi) the central chamber (12) is separated from each bag chamber (3) by a sealing section (4) and that the central chamber (12) has an equal distance to each bag chamber (3); and/or

   (vii) the minimum width of the sealing section (4) between a bag chamber (3) and the central chamber (12) is less than 5 mm, preferably less than 3 mm, further preferably less than 2 mm; and/or

   (viii) the central chamber (12) has a base surface in the sealing plane and that the base surface is circularly symmetric or n-count rotationally symmetric with n as the number of pouch chambers (3); and/or

   (ix) the central chamber (12) has a circular base surface or a polygonal base surface, preferably a square, triangular, star, propeller or fan wheel shaped base surface.
8. Detergent product (1) according to any one of the preceding claims, characterized in that

   (i) the bag chamber (3) has a base surface in the sealing plane and that the base surface is axis asymmetric; and/or

   (ii) the base surface is teardrop-shaped or yin-and-yang-shaped.
9. Detergent product (1) according to any one of the preceding claims, characterized in that

   (i) a surface bisector (10) of the base surface is left- or right-rotating and that, preferably, a left- or right-rotating arrangement of all bag chambers (3) is provided; and/or

   (ii) the width of the base area transverse to a bisector (10) of the base area and/or the crosssectional area of the bag chamber (3) perpendicular to the sealing plane initially increases over a portion of the length of the bisector (10) and decreases after reaching a maximum value.
