• article number 369 579 are tablets about 8 grams in weight, which are intended for about 2.5 liters of washing liquid.
• the problem is that these tablets are just too big and too heavy. If, for example, as is customary with certain vehicle types, one wishes to produce about 7 to 10 liters of window cleaning liquid, then correspondingly three to four such large tablets are required for this purpose. This corresponds to about 24g - 32g concentrate additive.
• the object of the invention is therefore a
• Another object of the invention is to provide for the tablet mold thus produced a packaging unit with which the window cleaner concentrate is easily and accurately dosed and still provides the necessary security against manipulation by children.
• a further object of the invention is to provide the disc cleaner concentrate according to the invention in tablet form in addition to the purely functional composition also further advantages in order to increase the marketability.
• the disc cleaner concentrate is very precisely metered for the amount of wash water present in each case, the tablet size generated in each case easily fits into the filling opening of any conventional washing water tank.
• the compacts for example, based on one to three liters of washing liquid, with a thickness of up to about 10 mm, a diameter up to about 15 mm occupy.
• the tablet has dimensioned for about 1 1 of water, a volume of about 0.5 cm 3. It is therefore relatively small, easy to handle tablets that can be dosed easily.
• the essential aspect of the invention is based on a surfactant content of more than 40% based on the raw material used.
• Cleaning aids such as phosphates and e.g. Dispense with trisodium nitrilotriacetate.
• This inert material must be such that it forms a complex with the surfactant without chemically reacting with the surfactant.
• This complex can be evaporated to a dry powder, which can then be compressed into tablets in conjunction with citric acid and sodium bicarbonate.
• the water-soluble inert material added to the aqueous surfactant solution forms a complex with the surfactants on a molecular basis without reacting with it.
• inert substance refers in this respect to the fact that the surfactants and the inert substance precisely no chemical reaction takes place, but only a complex compound.
• the evaporation of this complex is brought about in an advantageous embodiment of the invention by a process step in which under a temperature in the order of 50-60 °, a negative pressure of about up to 40 mbar is generated.
• the water contained in the surfactant solution which is supplied together with the inert material of the vacuum chamber, evaporate and be sucked off via a corresponding pump.
• the amount of citric acid can be up to about 35 percent by weight.
• the tablet according to the invention dissolves completely in water and all commercially available alcohol-containing antifreezes to 100%.
• inert substance e.g. Sugar into consideration.
• antifreeze materials do not have to be introduced into the tablets.
• the surfactants are originally in aqueous solution and are then concentrated by evaporation together with the inert material accordingly.
• the necessary aggregates which are also present in dry consistency, can be added.
• the mixture can already during drying or even later by conventional means also simply mix, before it is pressed in a corresponding tabletting machine.
• the disc cleaner concentrate is in a tablet form containing not more than 10 g, preferably not more than 5 g, of the mixed dried substrate.
• the individual tablet may also have no more than 2 g and would then be for half the amount of the basic volume of e.g. 2 liters of washing liquid to use.
• the additive sodium bicarbonate together with citric acid quickly dissolves bubbly and evenly in water, so that despite a high density of the tablets almost immediately after filling the washing water, the entire tablet contents went into solution.
• sodium bicarbonate together with citric acid, also has a certain cleaning effect, so that the surfactants contained as active ingredient are also assisted in their cleaning action.
• color pigments preferably color pigments, which correspond to the main dyeing of a previously determined customer group.
• This measure serves the purpose to offer the consumer individually colored tablets for sale, which fit into the product image of the respective provider due to their coloring - monochrome or multicolor.
• fragrances for example perfume oils
• the predetermined method to produce tablets which do not have to be provided with a circular cross-section.
• the tablets may have the outer contour of a scallop, a rhombus, a shield, or the like.
• This measure serves the purpose of documenting the corporate identity of a particular provider by means of the correspondingly contoured tablets.
• the tablet according to the invention can also be sold in a tablet tube.
• tablets were produced under a corresponding compression pressure whose density was about 2.5 g per cubic centimeter. Even such tablets were still slightly soluble in water and still small in volume at the desired high cleaning performance.
• the tablet is dissolved in the wash water as soon as possible by the use of sodium bicarbonate with citric acid alone.
• the tablet form so large that it together with a predetermined amount of water, also called base volume, for example 2 liters, has a sufficient cleaning effect.
• Fig.l a first embodiment of the invention.
• the windscreen washer tank of a motor vehicle is equipped on site with a tableted form according to the invention of a window cleaner concentrate.
• the container is filled with usual tap water. It is essential that the pane cleaner concentrate is tabletted and consists of a concentrate of evaporated surfactants previously present in aqueous solution, which were mixed with an inert material, for example with sugar, so that the dry consistency of the tablet 100 contains substantially highly concentrated surfactant.
• surfactants which are present in the evaporated concentrate of the original solution, including the inert material, which must be water-soluble, may be admixed with additives which were preferably also present in dry consistency.
• such a tablet 100 should not weigh more than 10 g, preferably not more than 5 g or, as a 1/2 dosage, not more than 2 g. ' >
• Tablets 100 can be produced which are suitable for about 1 liter of washing liquid at about 4 g in weight; correspondingly, a tablet 100 of up to about 2 g in weight would be suitable for about 1/2 liter of washing liquid.
• Citric acid may also be present as a further additive which, together with sodium bicarbonate, has a supplementary cleaning action.
• color pigments, fragrances or antifreeze additives can be provided in order to assign further functions to the tablet 100 according to the invention.
• So could e.g. be provided to equip such tablets 100 in red color with high concentrations of active ingredients, with green color with low concentrations, etc.
