Definitions

  • the invention relates to a metering element for introducing and distributing in particular powder detergent in a washing machine, with a flexible receiving bag made of water-permeable material, the upper opening edge being reinforced.
  • Dosing elements for detergents which are also used as dosing stores, 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 metering element is tipped over and the liquid detergent runs out into the laundry or the wash liquor.
  • Such dosing 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 metering element for liquid detergent.
  • a bag dosing element has already become known from EP-A1-40931, but is initially adhered to its opening edge and opens due to the movement in the drum and the laundry pressure. In particular, it is still unsatisfactory for use in powder 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  • a dosing element with a receiving bag has already been proposed by the applicant, in the unpublished patent application P 38 33 536.0.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 receiving 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 designed to be more user-friendly with simple training.
  • the opening edge is formed from elastically resilient strip elements, preferably plastic stiffening elements, which are arranged opposite one another, essentially perpendicular to a depth extension of the metering element, and can be displaced into an opening spacing against the effect of the restoring force by end loading.
  • the edge of the opening is therefore not formed by completely rigid elements, but by flexible elements which are resiliently bendable 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 so 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 metering element can also be handled in such a way that, in the open state, a portion of the edge is used as a scooping edge, which, because of 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 piece.
  • the elliptical or oval design of the strip elements and thus of the opening edge results on the one hand in a permanent opening which supports the flushing in of water or wash liquor for discharging 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 are gently spaced apart from one another in the unloaded state 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 rinse out the receiving bag from the inside and that Water can dissolve detergent.
  • the slightly gaping formation is also important in the respect 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 there is an opening load during the washing process due to the laundry pressure 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 lower curve can also be advantageous as a scoop.
  • the last-described embodiment is preferably formed from a single strip element that forms both sides of the opening edge with an approximately central bend, the free ends being unconnected, the configuration with the approximately central largest opening is preferably formed by two strip elements, the free ends of which are not connected to each other.
  • the invention also proposes that a strip element is curved in 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 easily possible.
  • the receiving bag can preferably consist of a nonwoven material. A non-woven plastic material that can be welded is advantageous.
  • 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 fleece 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 is open towards the bottom area of the receiving bag.
  • Such an insert bag initially forms, as it were, a non-return valve with regard to the detergent powder taken up.
  • the absorbed washing powder cannot be rinsed out immediately and at once. It turns out that at the beginning of the washing process, the washing powder is initially, partially, caught in the gusset between the receiving bag and the insert bag and is only dissolved 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 formed from nonwoven, and possibly also the insert bag is welded to its edge regions forming the side edges of the metering element.
  • one side edge of the metering element is designed as an envelope edge.
  • the bottom area of the dosing bag can also be designed as an envelope edge.
  • the edge envelopes, for receiving a strip element can also advantageously be formed by welding in terms of production technology, with a side edge weld running up to the edge area and passing through it completely. It may even be advantageous to have such a weld seam, in particular side edge weld seam, through the plastic To insert strip 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 therefore made smaller than a lower cross section of the receiving bag.
  • an approximately straight bottom line of the receiving bag merges into a corner region converging to the opening edge via a corner region formed with a curvature.
  • the receiving bag can be formed in the manner by two congruent blanks.
  • 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-A1 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.
  • the invention proposes in such a measuring spoon that the opening edge continues when leaving the oval shape in the handle area and delimits a shallow depression in the handle area in relation to the spoon trough.
  • the invention relates to a metering element in one of the configurations as described above, in which the strip elements forming the opening edge are designed to match the opening area of the spoon depression of the measuring spoon, as described above.
  • a metering element can be accommodated in the spoon area of the measuring spoon, which alone has advantages in terms of packaging technology.
  • the bag can be folded up and placed in the depth of the spoon area.
  • An embodiment is preferably provided such that the opening edge is supported essentially on the trough wall of the spoon trough, with the metering element being approximately completely immersed in the spoon trough. Due to the approximately parallel side walls and the circularly curved wall of the spoon depression, the inserted dosing element is supported in the front and rear area by resting on the circular trough wall by means of its opening edge, seen in the longitudinal direction of the spoon depression.
  • the dosing element 1 has a flexible receiving bag 2 made of water-permeable material. In the embodiments this material is a plastic nonwoven fabric that has pore-like openings.
  • the upper opening edge 3 of the metering element 1 is structured by elastically resilient strip elements 4, 5.
  • the strip elements 4, 5 are arranged opposite one another, substantially perpendicular to a depth T of the metering element 1. By loading the strip elements 4, 5 at the end, as is indicated, for example, in FIG. 8, the strip elements 4, 5 are in an opening Distance can be moved (cf. also here, for example, FIG. 8).
  • FIG. 6 shows a cross section through the upper opening edge region 3. It can be seen that the nonwoven fabric of the receiving bag 2 completely envelops the strip elements 4, 5.
  • FIG. 6 the section of the nonwoven fabric forming the covering of the strip elements 4, 5 is welded to the nonwoven fabric forming the receiving bag 2.
  • a longitudinal weld seam is formed below and parallel to the strip elements 4, 5.
  • the metering bag 2 is welded to the edge by longitudinal welds 7, 8.
  • the longitudinal welds 7, 8 go to an upper edge 3 ', so that the strip elements 4, 5 are completely enclosed in an envelope by the nonwoven fabric.
  • strip elements 4, 5 at their free ends 4 ', 4 ⁇ and 5', 5 ⁇ are not connected to each other. Rather, they are enclosed in the aforementioned closed chambers, which are formed by the welds in the nonwoven fabric at the opening edge 3.
  • FIG. 4 shows the object according to FIG. 1 in the filled, unloaded state.
  • the strip elements 4, 5 are slightly gaping apart in the unloaded state. There is therefore a constant opening of the metering element 1 even in the unloaded state. This is advantageous with regard to dispensing the detergent located in the metering element 1, and also with regard to an impossible or very difficult jamming or slipping of the metering bag between the drum and a rubber seal in the washing machine.
  • the greatest spacing between the strip elements 4, 5 is approximately in the middle of the opening edge 3.
  • the greatest spacing in the embodiment according to FIGS. 5-8 is offset to one side of the metering element 1.
  • This strip element 4a has a continuous curvature 9 on one side.
  • the strip element 4a accordingly forms both sides of the opening edge 3 in the embodiment according to FIGS. 5-8.
  • the free ends 4a 'and 4a ⁇ are not connected to each other.
  • the metering element 1 has an inner insert bag 10, which tapers downwards in a funnel shape and opens towards the bottom region of the receiving bag 2.
  • the insert bag 10 is connected to the receiving bag by the weld 6a, running parallel to a lower edge of the strip element 4a .
  • the receiving bag is also composed of two layers. There is still an average weld 11 with respect to each side wall of the receiving bag 2, but the side walls are not welded to one another in the area of the weld 11.
  • the side edge 12 is formed as a cover edge in the subject of FIG. 5. 1, the bottom region 13 is designed as a cover edge.
  • a receiving bag 2 can be formed, for example, by folding a strip across once and welding it off on the adjacent sides. Before that, the open ends are turned inwards and welded so that they each form a passage into which an elastically bendable strip element 4, 5 or 4a can be pushed.
  • the strip element can consist of an extruded plastic profile, e.g. B. made of polypropylene (PP). The aforementioned curvature ensures that the strip elements always form in opposite directions, ie form an opening.
  • Dosing bags can also be simply folded and bagged, for example to be added to a detergent powder container for sales.
  • FIG. 5 The object according to FIG. 5 is shown in FIG. 9, with the insert bag 10 turned outwards. This can occur during the washing process due to the washing solution flowing in and out. As a result, the receiving area for the powdered washing powder is enlarged by the washing powder being mixed with the water or the washing liquor and being dissolved therein.
  • FIG. 11 and FIG. 12 clearly shows the possible use of the opening edges 3 stiffened by the strip elements 4, 5 and 4a as scooping aids when filling in washing powder.
  • FIG. 12 shows a detailed detail view of the nonwoven fabric. It can be seen that approximately diamond-shaped openings 14 of very small size are formed in the nonwoven.
  • the opposite layers of a receiving bag are welded together in a weld seam area 7. A practically film-like consistency results in the weld seam area.
  • the material is also slightly transparent in the weld area.
  • the bag 10 is formed by lateral, inclined edges or seams (welded seams) 15 and 16.
  • welded seams welded seams
  • a dosing element 1 according to this application can have approximately the following dimensions (with reference to FIG. 9): width B approx. 15 cm, height H approx. 17 cm, height of an envelope for receiving a strip element 4, 5, H u approx. 2 cm , wherein the width of a strip element 4, 5, 4a is about 1.5 cm.
  • the constant opening width ⁇ can be about 3 - 5 cm.
  • the opening edge is formed by a single strip element 4 which is endless, for example it can be welded at its ends.
  • the strip element 4 as described above with reference to FIG. 2, is encased by the nonwoven material of the receiving bag 2.
  • the metering element 1 according to FIG. 13 can also be set into an opening spacing by loading the strip element 4 at the end.
  • the exposed area 19 of the strip element 4 can also be seen from the view according to FIG. 14. Moreover, it can be seen from FIGS. 13 and 15 that the receiving bag 2 is designed to widen towards the bottom. It has an approximately straight bottom line 20, which merges into corner regions 7, 8 converging towards the opening edge via corner regions formed with a curvature 21 or 22.
  • the receiving bag 2 can consist of two congruent layers of fleece be formed, a design, such as that shown in Fig. 16 for a side position.
  • FIG. 17 shows a top view of a measuring spoon 23, which is also used for dosing detergent, in particular powder.
  • the measuring spoon 23 has a handle area 24 and a spoon area 25.
  • the spoon area 25 has an approximately oval-shaped opening edge 26.
  • the opening edge 26 goes out of the oval shape of the spoon area 25 in the stem area 24 at 26 'and there delimits a shallow depression 27, which is also formed with a smaller width than the stem area 24.
  • the depression 27 is also formed with a smaller depth than the spoon region 25.
  • a trough wall 30, which closes the spoon trough 25 and connects the side boundary walls 28, 29, is generally approximately circular, as can be seen in particular from the side view according to FIG. 18. From Fig. 18 it can also be seen that the trough wall 30, leaving the circular shape, merges into the bottom of the recess 27.
  • FIGS. 17 and 18 show a measuring spoon 23 according to FIGS. 17 and 18 combined with a metering element 1, as is shown in particular in FIGS. 13-16. It can be seen that the strip element 4 conforms to the shape is formed on the opening edge 26 of the measuring spoon 23.
  • the receiving bag 2 of the metering element 1 is folded up and received in the spoon depression. Due to the recess 27 in the stem area 24 of the measuring spoon 23, it is possible to simply remove the dosing element from the spoon area for use.
  • the design is such that the opening edge of the metering element 1 is essentially supported on the trough wall 30 of the spoon trough 25, specifically in the area assigned to the depression 27 and in the opposite area, at the front end of the measuring spoon 23
  • the opening edge of the dosing element 1 and thus the entire dosing element 1 is completely accommodated in the measuring spoon 23, such that the upper edge of the opening edge of the dosing element 1 ends approximately with the edge of the measuring spoon 23 in a side view according to FIG. 20.
