Definitions

  • the invention relates to a device for dispensing a certain amount of detergent.
  • the detergent usually had to be removed from a detergent package with a measuring cup. Direct skin contact with the detergent is generally unavoidable. There is also the risk that detergent is spilled, dusty particles of the detergent are inhaled or children can come into contact with the detergent. It is also known that the dosage instructions are often not followed or only inaccurately.
  • the object of the invention is to create a dosing system which no longer has these disadvantages.
  • the device according to the invention in particular avoids direct skin contact or dust formation and can therefore effectively prevent any allergies.
  • the risk that children can come into contact with the detergent is considerably reduced, since the detergent is only released when the casing is dissolved in the water.
  • the fact that the detergent is in the form of certain detergent portions also makes dosing easier and also ensures that the dosage regulations are adhered to, since it must be decided in each case how many detergent portions are to be used.
  • the detergent should be completely encased by the water-soluble casing and that the material used for the casing should be compatible with the detergent in order to avoid impairing the detergent action.
  • the water-soluble casing expediently consists of a water-soluble, residue-free material.
  • the material should therefore be sufficiently soluble, at least at the respective washing temperature, that rapid release of the detergent is ensured and no residues remain on the laundry.
  • a material is preferably used which is readily water-soluble above 20 ° C., which allows use at all customary washing temperatures.
  • Suitable, water-soluble materials are known to the person skilled in the art and are commercially available. Preferred are materials that can be processed into films, in particular polymers and other macromolecules with similar properties. Examples of suitable materials are polyvinyl alcohol, water-soluble derivatives of polyvinyl alcohol, water-soluble cellulose derivatives such as carboxymethyl cellulose, methyl cellulose, hydroxyethyl cellulose and hydroxypropyl cellulose, cellulose ethanesulfonic acid, water-soluble starch, polyvinyl pyrrolidone, gelatin and the like. The material should preferably be environmentally friendly; materials which occur naturally and / or are biodegradable are particularly preferred.
  • the amount of detergent contained in the device according to the invention can preferably be coordinated with respect to the degree of hardness of the washing water and / or the amount of laundry. For practical reasons, it is generally preferred to use uniform detergent portions.
  • the amount of detergent per serving can, for example, be selected so that it is just sufficient for a small amount of laundry (eg 3 kg) and a low to medium degree of hardness (eg 10 to 20 fH). For harder water and / or larger amounts of laundry, two or more servings are used as required.
  • the detergent can thus be dosed as shown in the following table by way of example:
  • the device according to the invention can be produced in a manner known per se, in particular according to the methods which are well known to the person skilled in the art for packaging any goods in a film.
  • the detergent can be introduced in portions between two foils or into an endless tube made of the water-soluble material, and the foils or the tube can be welded or glued between the detergent portions. If desired, the sealed portions can be separated or perforated at the welded or glued points.
  • the shape of the device according to the invention is immaterial. The only important thing is that the detergent is completely sealed and the casing is water-soluble. For practical reasons, however, a shape as shown in Fig. 1 is usually used.
  • FIG. 1 thus shows, in elevation and in 2 cross sections perpendicular to one another, a preferred embodiment for the covering of the detergent (1) with a water-soluble covering (2).
