Definitions

  • the invention relates to a dispenser for washing powders, or the like, in automatic washing machines.
  • the washing powders and others additives are supplied to compartments, from which they are entrained and supplied to the drum of the machine by the washing water that flows through the compartments before being suppliede to the drum.
  • this way of proceeding presents the drawback that the washing water is not able to entrain the whole amount of powder compond, thus leaving in the said compartments, residual amounts of solids consisting in powder compound agglomerations adhering to them.
  • the required compound concentration in the drum to obtain the optimum actives principles exploitation is not achieved. The dissolution of the compound results even incomplete and often a certain amount of not dissolved powder settle on the drum bottom.
  • An object of the invention is to realize a dispenser for washing powders or the like that enables the elimination of the above disadvantages and an optimum exploitation of the washing powder and additives, by creating best distribution and dissolution conditions.
  • the present invention achieves said object by providing a dispenser for washing powders or the like, in automatic washing machines, consisting of a container for the washing powders or other kinds of powder compounds for washing, that is intended to be placed directly in the drum of the washing machine together with the linen and that is reusable for an indefinite number of subsequent washings, the container being realized in a material permeable to water and to the powder compounds in their dissolved form, as well as insoluble in water and being provided with openable closure means which remain in closed position during the whole washing step, so that washing powder or additives are progressively delivered in their completely dissolved condition in water, only through the container walls.
  • the container is realized as a floppy bag and can be made by any kind of material that is rather porous to allow the penetration of the washing water inside the walls and the progressive outside passage towards the exterior of the solution containing water, washing powders and other washing compounds. It can be for example made of fabric, nonwoven fabric, either of natural or of synthetic fibers, or combination thereof, whose wefts show by themselves a sufficient porosity or that are provided with microholes or normal holes with a predeterminated size lesser than the granulometry of the powder compounds and with a predeterminated ratio between the total area of the holes and the walls area. Even particular kinds of papers or sheets of fibrous or synthetic material, like plastic material or the like with desired porosity, can be used.
  • the openable closure means can be of any kind, and preferably consisting closure strings of the kind usually employed in other fields for closing small bags.
  • the dispenser according to the invention allows to regulate freely the doses of washing powder or additive that one wants to use.
  • the container comes in contact with the whole volume of washing water, distributing progressively and uniformly the washing powder and other washing compounds. This assures the maximum effectiveness of products and also assures an optimum washing.
  • the container softness and deformability eliminate the danger of damaging the container itself and the drum, and the noisiness in bumps.
  • the compressibility of the container assures the whole exploitation of the dose of washing powder or additive, avoiding wastes or unsatisfactory washing results.
  • the container according to the invention is formed by a small bag 1 of rectangular shape.
  • the small bag 1 can be made of fabric, nonwowen fabric or formed by a sheet of water-insoluble material, permeable to water and to the solution of water and washing powder or additive. This can depend on the inherent porosity of the employed materials that can be made of natural or synthetic fibers or a combination thereof, or can be obtained forming a number of holes or microholes, the size of which is lesser than the granulometry of the powder compounds, in order to prevent its discharge in dry conditions.
  • the small bag 1 presents a flat envelope-like shape and is open along one of the peripheral edges of its two faces.
  • the peripheral edge 2 of each face, near the opening, is realized in tubular form in the shape of a slot, and is open at the opposite head sides.
  • two closure pull elements 3, 4, for example two strings which are closed on themselves and extend in both tubular edges 2 of the faces, surrounding the opening. The closure of the upper edge 2 of the small bag 1 is obtained by pulling the strings 3, 4 in opposite directions.
