Definitions

  • the invention relates to a portion unit of a powdery cleaning agent, comprising a closed bag and a unit dose of the powdery cleaning agent received in the bag.
  • cleaning agent encompasses any washing and cleaning agent compositions which are suitable for use in a washing machine and / or a dishwasher.
  • Powdered cleaning agents are understood to mean cleaning agents that are in the form of granules and / or powder, as opposed to liquid and gel-like cleaning agents.
  • Portion units of this type can be designed, for example, as so-called “pouches”, in which a unit dose of a generally liquid or gel-like cleaning agent is enclosed in a packaging unit formed by film sections sealed together at the edges.
  • the packaging unit is advantageously made from a water-soluble material so that the portion unit can be placed in the washing machine or dishwasher as a whole. The water-soluble packaging unit dissolves in the cleaning water and the cleaning agent is released.
  • Liquid and gel-like cleaning agents require a liquid-tight packaging unit, formed for example from a film material, in order to prevent the cleaning agent from leaking out of the packaging unit.
  • packaging units are also known for solid, granular and / or powdered cleaning agents which are made from flat textile structures, for example from a woven fabric or a fleece.
  • portion units based on textile fabrics are also known, so-called detergent wipes or “laundry sheets”, in which a unit dose of a detergent composition is incorporated into a textile fabric and this cloth is placed in the washing machine as a whole. During the wash cycle, the cloth dissolves and releases the detergent composition. It has been shown, however, that with this dosage form, in general, no good washing performance can be achieved, since the concentration of washing agent that is achieved in the washing liquor is not sufficiently high. In addition, it has proven difficult to incorporate perfuming substances into such detergent wipes.
  • the present invention has set itself the task of providing a portion unit of a powdery cleaning agent which overcomes the disadvantages of the prior art and which is easy to handle both for an end user and during transport and storage. It is a further object of the invention to provide a method for producing such portion units.
  • the invention is a portion unit of a powdery cleaning agent, comprising a closed bag and a unit dose of the powdery cleaning agent received in the bag, the bag being formed from a textile fabric made of a water-soluble material and at least two each by one Seam section comprises compartments separated from one another, wherein a proportion of the unit dose of the powdery cleaning agent is received in each compartment and wherein the individual seam sections are formed from a water-soluble yarn.
  • the invention provides that the bag enclosing the unit dose of the powdered cleaning agent is formed from a textile fabric, for example from a fleece or woven fabric or knitted fabric or knitted fabric or felt, which in turn is formed from a water-soluble material. It is due to the way in which such portion units are produced that it is not possible to fill the bags to the brim with cleaning agent. A significant unfilled space therefore always remains within the bag. Due to the loose bulk, this leads to the powdery cleaning agent collecting in one area of the bag and possibly bulging the bag in this area, while other areas of the bag appear empty. In order to counteract this circumstance, the invention provides that the bag comprises at least two compartments which are separated from one another by a seam section formed from a water-soluble yarn. A proportion of the unit dose of the powder cleaning agent is included in each compartment. A compartment is understood to mean a chamber in which a portion of the unit dose of the cleaning agent is enclosed.
  • the entire internal volume of the bag is thus divided by seam sections into at least two, preferably more than two, separate compartments which each hold a proportion of the unit dose of the powdery cleaning agent.
  • the detergent is distributed more evenly within the bag and an accumulation in a single area of the bag can be prevented.
  • this leads to an improved aesthetic impression for a consumer and, on the other hand, is what forms the bag Material less stressed.
  • such portion units can be layered in a smaller overall packaging in a more space-saving manner, whereby space and thus costs can be saved both in storage and in transport. It is not necessary here for the proportions of cleaning agent taken up in the individual compartments to be exactly the same. However, an essentially even distribution of the cleaning agent over the individual compartments is advantageous.
  • the bag including the seam sections dissolves in the cleaning water without leaving any residue and the cleaning agent is released.
  • a textile fabric has the advantage over a film film that, due to the open-pore structure of such materials and the associated air permeability, perfume substances that are added to the detergent composition are immediately perceptible to the consumer when the outer packaging is opened.
  • a closed bag made of a textile fabric is understood to mean a bag which does not include any openings beyond the pores present in the textile fabric.
  • the bag does not include any openings and / or pores whose size is larger than the grain size of the particles forming the powdery cleaning agent.
  • a seam or a seam section within the meaning of the invention does not include a seam between two compartments caused by sealing or welding the two layers of material forming the bag. Sealing or welding can only be used to form the bag itself, that is to say to connect two layers of material at the edge to form a bag, which will be described in more detail, but not for the formation of a seam section separating two compartments.
  • the seam sections according to the invention can be made in different sewing stitches.
  • a proposal of the invention provides that at least one seam section is executed in a lock stitch.
  • at least one seam section is designed in a zigzag stitch.
  • Other sewing stitches may also be suitable.
  • all seam sections of a bag can be made in the same sewing stitch or in different sewing stitches. Both the stitch length and the fineness of the thread of the water-soluble yarn used are based on the grain size of the powdery yarn filled into the bag Cleaning agent matched so that particles of the cleaning agent cannot pass through a seam section and / or through a puncture point in the textile fabric caused by the needle.
  • the lines of the seam sections can also vary.
  • at least one seam section can be designed in a straight line.
  • at least one seam section can be designed, at least in sections, as a curved line.
  • the individual seam sections can particularly preferably be sections of a single, continuous seam. This is to be understood in particular that in a bag with more than two compartments, the seam sections separating the compartments can be designed as a continuous seam in one approach, in such a way that a seam section directly adjoins a preceding seam section. In contrast, it can alternatively be provided that several compartments are separated from one another by seam sections which are designed as individual seam sections that are separated from one another.
  • the textile fabric is designed as a nonwoven material.
  • the textile planar structure can also be designed, for example, as a woven or knitted fabric or knitted fabric or felt.
  • the material of the textile fabric comprises polyvinyl alcohol (PVOH).
  • PVOH polyvinyl alcohol
  • Polyvinyl alcohol is a water-soluble polymer.
  • the PVOH polymer can comprise a PVOH homopolymer and / or a PVOH copolymer, in particular it can comprise several different PVOH homopolymers and / or several different PVOH copolymers.
  • the water-soluble yarn from which the seam sections are formed also comprises polyvinyl alcohol (PVOH).
  • PVOH polymer can comprise a PVOH homopolymer and / or a PVOH copolymer, in particular it can comprise several different PVOH homopolymers and / or several different PVOH copolymers.
  • the invention also comprises a method for producing a portion unit of a powdery cleaning agent, comprising the following steps: providing a textile fabric made of a water-soluble material;
  • the method according to the invention thus provides that subsequent compartmentalization is carried out only after the bag has been filled and completed by providing the filled bag with at least one, preferably several seam sections in such a way that the inner volume of the bag is divided into several separate chambers or compartments is divided, in each of which a portion of the unit dose of the powder detergent is included.
  • the cleaning agent is preferably distributed essentially uniformly within the closed bag, so that an excessive accumulation of cleaning agent in a single compartment can be avoided. Due to the small width of a seam formed with a needle and thread, there is no risk that large quantities of cleaning agent will become stuck in the area of the seam. In the case of a seam subsequently brought about by welding or sealing, on the other hand, there would always be a larger amount of detergent powder between the sealing jaws. Such seams are therefore not provided in the context of the present invention for separating individual compartments.
  • the bag can be formed from two identically shaped material layers of the textile fabric, whereby a first material layer is initially provided, a unit dose of the powdery cleaning agent is applied to this first material layer, then the second material layer is placed on the cleaning agent so that the first and the second material layer including the cleaning agent are essentially congruent on top of one another and finally the two material layers are closed by edge-side welding or sealing or sewing to form a bag containing the cleaning agent.
  • the bag can be formed from a single, correspondingly larger-sized material layer of the textile fabric, to which the unit dose of the powdery cleaning agent is applied and which is then folded in the middle.
  • the bag is already closed in the area of the fold break and only the remaining edge areas have to be closed by sealing or welding or sewing.
  • the material layers used to form the bag can, for example, have a round or elliptical or polygonal, in particular rectangular, shape.
  • the bag can be produced from a tube section formed from the textile fabric by adding the unit dose of the powdery Cleaning agent introduced into the hose section and this is closed on the two open sides by welding or sealing or sewing.
  • the subdivision into individual compartments is always made only after the bag has been closed, for example by applying one or more seam sections that penetrate and connect the two material layers of the bag with the aid of a sewing machine.
