Definitions

  • the invention relates to a detergent capsule with an outer shell based on a plastic film, which encloses at least one inner receiving space in which detergent or detergent components or laundry care products are accommodated.
  • the term detergent includes any detergent and cleaning agent compositions that are suitable for use in a washing machine and / or a dishwasher.
  • Laundry detergents are also to be understood as laundry detergents.
  • Laundry care products are, for example, fabric softeners or fragrance formulations, which may be free or almost free of detergent substances such as surfactants, but scent or condition the laundry.
  • detergent capsules in the sense of the invention.
  • These detergent capsules are particularly user-friendly thanks to a water-soluble packaging in the form of an outer shell based on a plastic film, with which a single dose of the detergent can be added directly to the machine.
  • the water-soluble outer shell dissolves in the washing water and the detergent is released. In this way, a user does not come into contact with the detergent, which is found to be very advantageous.
  • Such detergent capsules are for example in the DE 10 2014 014 767 A1 described.
  • Multi-chamber systems in which a single dose of the detergent is enclosed in a single receiving space formed by the outer shell, for example, from DE 10 2015 204 170 A1 and from the WO 02/085736 A1
  • Multi-chamber systems are also known, in which the outer casing has a plurality of separate receiving spaces, each of which is filled with a portion of the detergent dose. It can be provided that all of the receiving spaces of the detergent capsule designed as a multi-chamber system are filled with the same detergent composition, but different components of the detergent can also be enclosed in different receiving spaces.
  • Such detergent capsules of the type explained above represent a growing market.
  • the amount of detergent dosage contained in a single detergent capsule or its individual components can be carried out differently, for example 25 g for premium products, 22 g for middle-class products and 20 g for particularly inexpensive products.
  • this is also sufficient lower dosages depending on market requirements, washing conditions and consumer expectations of the requirements to be achieved.
  • a lower detergent dosage within a single detergent capsule is therefore desirable from an economic and also an ecological point of view.
  • a lower dosage of the detergent or detergent components can be filled into a standard form of a detergent capsule that fulfills the required minimum size and the minimum volume, but due to the oversized volume and the size of the detergent capsule, this causes a correspondingly large air bubble in the remaining free receiving space of the detergent capsule . Even if the weight declaration on the packaging and the actual filling quantity are correctly indicated, such large air bubbles in the detergent capsule produce a negative impression on the consumer, since they suggest that the filling is too low.
  • the overall dimensions of the detergent capsule can be changed, so that a large surface is obtained with a detergent capsule that is rather flat.
  • Such flat detergent capsules with a flat design prevent the risk of inadvertent ingestion, but are not accepted to the desired extent by the consumer.
  • the object of the invention is to propose a detergent capsule of the type mentioned at the outset and a method for its production which, even with a reduced dosage of the Detergent compartment or detergent components accommodated in the receiving space have an expansion similar to the spatial extent of the detergent capsule previously established on the market, but excessive formation of air bubbles in the receiving space is prevented, the production being to be carried out with little effort, if possible, using existing systems.
  • the solution according to the invention provides that at least one receiving space of the detergent capsule has at least one sealing seam introduced in some areas, which partially, but not completely, divides the receiving space.
  • This internal sealing seam is designed such that it is either contact-free to a peripheral edge which defines the receiving space and which preferably has a substantially constant width, or that when it comes into contact with this peripheral edge there is no closed volume in the form of an additional chamber. A single contact of the introduced sealing seam with this peripheral edge is therefore possible. In this case, the internal sealing seam would extend from the peripheral edge into the interior of the receiving space.
  • the detergent capsules designed according to the invention have an appealing and modern design by the consumer, which results in a correspondingly good market acceptance.
  • the detergent capsule according to the invention only has a single inner receiving space, which is also referred to as a mono-pouch, this receiving space is provided according to the invention with at least one sealing seam introduced in some areas.
  • the detergent capsule according to the invention has a plurality of, for example two to four, discrete, ie separate, reception spaces, a single, several or all of the receiving spaces are each provided with at least one sealing seam according to the invention.
  • a preferred embodiment of a detergent capsule according to the invention only comprises a receiving space with a sealing seam introduced in some areas.
  • the sealing seam introduced according to the invention divides the receiving space only partially, i. H. precisely not in a complete manner, which would result in a subdivision into further reception spaces, but only to the extent that the volume of the originally existing reception space is limited, but still all areas of the reception space communicate with one another and together contain the intended detergent or serve the detergent component.
  • the sealing seam can protrude from the circumference of the outer shell into the receiving space and is partially surrounded by the receiving space, which surrounds the sealing seam in the manner of a C, S, Z or U.
  • the detergent or detergent component filled into the receiving space is also arranged accordingly.
  • the sealing seam is completely surrounded by the receiving space, which then extends in a top view from above approximately in an annular manner around the preferably centrally inserted sealing seam and the detergent or detergent component filled into the receiving space is also arranged accordingly.
  • the introduced sealing seam reduces the originally existing volume of the receiving space of the detergent capsule according to the invention, which is too large for the metered detergent or the detergent component, in the area of the sealing seam so that an air bubble in the receiving space is minimized or ideally completely eliminated.
  • the outer shell of the detergent capsule according to the invention can be formed by two film layers connected to one another on the edge and in the region of the at least one sealing seam.
  • the connection can be effected, for example, by pressing and / or welding.
  • the plastic film for forming the outer shell is preferably water-soluble, for example by being based on polyvinyl alcohol (PVA).
  • PVA polyvinyl alcohol
  • the films that can be used generally consist of polyvinyl alcohol copolymers with appropriate additives such as plasticizers, surfactants, bitter substances or salts.
  • Such a plastic film can be produced, for example, in the casting process (solvent casting) or blow-extrusion process.
  • the plastic film can also be formed in one or more layers, for example in two layers.
  • the film can optionally be printed or decorated on the inside or outside, for example with consumer information and pictograms.
  • the print can be multi-colored and water-soluble or water-insoluble inks can be used.
  • the design and dimensioning of the at least one sealing seam of the detergent capsule provided according to the invention is not subject to any general restrictions and can be determined by the person skilled in the art in accordance with the objectives to be achieved.
  • the sealing seam has a width of approximately 0.5-5 mm, preferably 1 to 5 mm, more preferably 0.5 to 3 mm, or also more than 5 mm or more than 1 cm .
  • the sealing seam can be straight, for example in the manner of a separating web or in any free form.
  • the sealing seam can be U-shaped, V-shaped, triangular or circular.
  • this freeform can have dimensions of up to 25 x 25 mm or, in the case of a circular shape, diameters up to 25 mm, or preferably dimensions of up to 10x10 mm, or in the case of a circular shape, up to 10 mm.
  • Larger or elongated sealing seams are also conceivable. In any case, the sealed seam does not enclose a cavity filled with detergent, but is only surrounded by one.
  • a detergent capsule W1 of the prior art has a base area (length L by width B) of 2.3 cm ⁇ 3.1 cm and a height H of 2.0 cm, measured without the laterally projecting sealed edge. Due to the small width of 3.1 cm and length of 2.3 cm, the handling is reduced and the risk of swallowing is increased.
  • Another detergent capsule W2 of the prior art solves this problem by means of an increased length and width. However, considerably more detergent or air has to be filled in as a result, which disadvantageously increases the manufacturing outlay and the storage volume.
  • the detergent capsule W3 according to the invention also has an increased length and width, but also has only a small internal volume, thus avoiding all of the aforementioned disadvantages.
  • a method for producing a detergent capsule according to the invention provides that in a first step a layer of a plastic film is guided onto a cavity which has an edge and an internal elevation for forming the sealing seam.
  • the plastic film is deep-drawn or vacuum-deformed into the at least one cavity, preferably with heating and optionally supported by compressed air, so that the film has an elevation on the inside.
  • the elevation preferably has the same height as the edge, measured from the bottom of the cavity.
  • detergent or detergent components are filled up to the height of the elevation in the cavity lined with the plastic film, so that the top of the result, which is preferably flat, is free of detergent or detergent components.
  • the cavity is then closed by placing a further film, and the further film is welded to the edge and on the elevation to the plastic film.
  • the sealing seam is formed by welding the plastic film and the additional film on the elevation.
  • a further method for producing the detergent capsule according to the invention makes use of existing plant technology for easy implementation and implementation in that in a first step a layer of the plastic film is placed on at least one cavity which has no internal elevation to form the sealed seam.
  • the plastic film is deep-drawn or vacuum-formed in the at least one cavity, preferably with heating and optionally supported by compressed air, so that the film takes on the contour of the cavity.
  • detergent or detergent components are filled into the cavity lined with the plastic film.
  • the cavity is then closed by placing a further film, and the further film is welded to the edge of the plastic film. Before or after this welding, the detergent or the detergent components are displaced between the foils by pressing on the two foils, and the sealing seam is formed in this area by welding.
  • connection of the layers of the plastic film to form the edge areas and / or the sealing seam of the detergent capsule according to the invention can, for example, under the action of water and pressure or under the action of water, pressure and heating below a temperature of about 95 ° C or under the exclusive action of temperatures above of 90 ° C.
  • the resulting flange-like edge areas can be removed, for example, by a subsequent laser cut or punching or cutting.
  • a detergent capsule identified globally by reference number 1, can be seen, which has an outer shell 10 based on a water-soluble plastic film, for example made of polyvinyl alcohol.
  • the outer shell 10 encloses an inner receiving space 11, which is closed on all sides and in which a liquid or gel-like detergent, for example, is accommodated in a dosage of, for example, 20 g sufficient for a single washing process.
  • the outer shell 10 dissolves from the water-soluble plastic film upon contact with the washing water and releases the detergent held in the receiving space 11 in the desired dosage.
  • the dimensions of the detergent capsule 1 are in relation to the filled dosage of the detergent in the receiving space 11 itself chosen too large.
  • the volume of the inner receiving space 11 is reduced to such an extent by a sealing seam 12, which is partially introduced into the receiving space 11 and which is completely surrounded by the receiving space 11 and the detergent contained therein, that there is no air bubble in the receiving space 11 in addition to the introduced detergent.
  • the outer casing 10 is formed by connecting a lower and an upper layer of the plastic film to one another at the edges, including the metered detergent, in a manner not shown, for example thermally welded by the action of temperatures above 95.degree.
  • a flange-like peripheral area 100 is formed, which can be removed by punching or laser trimming if necessary.
  • the two layers of the plastic film in the area of the introduced sealing seam 12 are brought into direct contact with one another and connected to one another, for example thermally welded, so that the detergent filled in the receiving space 11 is displaced in the area of the sealing seam 12.
  • the two layers of the plastic film can also be connected to one another by the action of water, pressure and temperatures below 95 ° C. or by the action of water and pressure.
  • the size, dimensioning and design of the sealing seam 12 can be chosen freely by the person skilled in the art on the basis of the circumstances, provided that it is ensured that the receiving space 11 is not divided into two completely separate subspaces by introducing the sealing seam 12.
  • at least one free end of the sealing seam 12 must be partially surrounded by the receiving space 11 or, as in the exemplary embodiment shown, completely surrounded by the receiving space 11.
  • the detergent capsule 1 explained above can thus hold, for example, a dosage of 20 g of the detergent in the receiving space 11, but the outer dimensions correspond to a detergent capsule 1 for holding 24 g of the detergent, by introducing the sealing seam 12, an otherwise inevitably existing air bubble in the receiving space 11 is largely avoided.
