Definitions

  • the invention relates to a dosing element for introducing and distributing, in particular, powder detergent into a washing machine, with a flexible receiving bag made of water-permeable material, the upper opening edge being reinforced.
  • Metering elements for detergents which are also used as metering devices, have already become known in various configurations.
  • Liquid detergent is poured into such dosing balls from above through a suitable opening and the filled dosing element is then inserted into a washing machine filled with laundry.
  • the dosing element is tipped over and the liquid detergent runs out into the laundry or the wash liquor.
  • Such metering elements are not yet satisfactory in every respect.
  • powdered or pasty detergent in a metered amount cannot be used directly in the laundry with such a known metering element.
  • powder detergent can be poured into a known dosing element for liquid detergent.
  • a dosing element with a receiving bag has already been proposed by the applicant, in the unpublished patent application P 38 33 536.0.
  • the upper edge of the receptacle bag is provided with a rigid insert part which forms a dispensing opening and filling aid.
  • the object of the invention is to provide a metering element for introducing and distributing, in particular, powdered detergent in a washing machine, which is of a more simple design with a simple design.
  • the opening edge is formed from elastically resilient strip elements, preferably plastic strip elements, which are arranged opposite one another, essentially perpendicular to a depth extension of the metering element, and by end loading against the effect of the restoring force into a Opening spacing can be moved.
  • the opening edge is therefore not formed by completely rigid elements, but by flexible elements which can be resiliently bent in transverse sections perpendicular to their longitudinal extension. In a longitudinal cross cut the strip elements are little or not elastically deformable.
  • the user can take the dosing element in his hand in such a way that he exerts pressure on the end of the strip elements, which then move away from one another. Washing powder can be poured into the opening.
  • the dosing element can also be handled in such a way that, in the opened state, a portion of the edge is used as a scooping edge which, owing to its stability, can be pressed into a supply of washing powder and drawn through.
  • the strip elements are elliptical in the unloaded state.
  • the strip elements can also mean that the opening edge is formed by a single strip element. This can be connected to one another at its ends, for example welded, to form the one-piece structure.
  • the elliptical or oval design of the strip elements and thus the opening edge results on the one hand in a constant opening which supports the washing in of water or wash liquor to discharge the washing powder at the start of the washing process, and on the other hand it is also advantageous in terms of handling.
  • the strip elements in the unloaded state are slightly gaping from one another in such a way that in any case there is a constant inflow opening for the water or the wash liquor during the washing process, and the water or the wash liquor is the receiving bag rinse from the inside and can remove the detergent dissolved in the water.
  • the slightly gaping design is also important in that the metering element cannot get between the drum and the rubber seals of a washing machine because of its otherwise thin, cloth-like design, in the unfilled or emptied state.
  • a piece of laundry in the The edge of the opening may be pinched if the laundry pressure results in an opening load during the washing process and then the strip elements reset due to their resilience.
  • the greatest spacing of the strip elements is given approximately in the middle of the strip elements, ie also approximately in the middle over a width of the metering element.
  • the greatest spacing is offset to one side of the metering element. This in the configuration that there is an opening cross-section which is approximately, even if distorted, drop-like.
  • the lower curve can also be advantageous as a scoop. While the last-described embodiment is preferably formed from a single strip element which forms both sides of the opening edge by means of an approximately central bend, the free ends being unconnected, the configuration with the approximately central largest opening is preferably formed by two strip elements whose free ends are not connected to each other.
  • the invention also proposes that a strip element has a curved cross section, the curvature opening pointing outwards.
  • the curved design results in a high stability in the longitudinal direction of the strip elements, while an elastic bending in the transverse direction is readily possible.
  • the receiving bag can preferably consist of a nonwoven material. A non-woven plastic material that can be welded is advantageous. Alternatively, the receiving bag can also consist of a textile, water-permeable material.
  • the strip elements and the design of the upper opening edge area the invention also proposes that the strip elements be completely covered by the nonwoven material. She is For example, advantageous with regard to a very low noise level of the metering element during a washing process.
  • the nonwoven material or other material from which the receiving bag is made has a sound-absorbing effect with respect to the strip elements.
  • the invention proposes that the receiving bag has in its upper section assigned to the opening edge area an insert bag which tapers downwards in a funnel shape and opens towards the bottom area of the receiving bag.
  • Such an insert bag initially forms, as it were, a check valve with respect to the detergent powder taken up.
  • the washing powder taken up cannot be rinsed out immediately and at once. It turns out that, at the beginning of the washing process, the washing powder initially, partially, gets caught in the gusset between the receiving bag and the insert bag and only dissolves over time and passes into the water or the washing liquor.
  • the insert bag is connected to the inside, below the opening edge area and parallel to it, preferably also welded.
  • the receiving bag made of nonwoven, and possibly also the insert bag is welded to its edge regions forming the side edges of the metering element.

  • the nonwoven fabric is welded to the plastic strip element and the strip element is fixed in the edge envelope.
  • the receiving bag is designed to widen to the bottom. The opening edge is thus made smaller than a lower cross section of the receiving bag.

  • the measuring spoon has a handle area and a spoon area, the spoon area being formed with an approximately oval-shaped opening edge.
  • a measuring spoon is known, for example, from EP-AI 253 419, it being possible for the handle area in this known measuring spoon to be used at the same time to cover the spoon area. Otherwise, the handle area can be plug-connected there with the spoon area.
