Definitions

• the present invention relates to an additive product intended, in combination with the water contained in a flush tank of a toilet, to ensure the treatment of the walls thereof and the walls of the bowl associated therewith .
• the present invention also relates to a treatment agent consisting of this additive with water from a flush tank of a toilet.
• a flush tank is fed sometimes by raw water from a tap of the water distribution network, sometimes sometimes by recycled water, that is to say water having previously been used, such as for example showers, rainwater etc. .. This results in a number of inconveniences for the user.
• the tank and bowl of a toilet are also the seat of development of other pollutants consisting of microorganisms that are the source of many inconveniences and in particular causing unpleasant odors.
• Such products are therefore designed to act directly and neatly on the surfaces to be treated, so that they lose their effectiveness when they are in the diluted state, so that they are totally unsuited to the treatment of the walls of a tank and a bowl of a toilet, by distribution in the water contained therein.
• the object of the present invention is to propose an additive product that can be distributed in particular by this type of apparatus, and which, in combination with the water contained in a flush tank of a toilet, is capable of ensuring treatment of both the walls of this tank and the walls of the bowl associated therewith, on the one hand to avoid the formation of various deposits previously mentioned and on the other hand to promote the maintenance of mechanisms of the dispensing apparatus.
• Such a product also allows promote the maintenance of the air in the room surrounding the toilet.
• the subject of the present invention is thus a liquid additive product, comprising at least one acid, intended, in combination with the water contained in a flush tank of a toilet, to constitute a pollutant treatment agent contained in the tank, characterized in that:
• this acid is an organic acid, in particular a natural organic acid, the concentration by weight of which is at least 30%.
• the additive product will preferably comprise at least two organic acids, preferably natural ones, at least one of which acids may be citric acid, acetic acid or oxalic acid. At least one of the organic acids may also be a synthetic acid, in particular belonging to the group consisting of polyacrylic acid, or polymalanine acid or phosphonic acid.
• the additive product according to the invention will advantageously contain at least one element capable of at least slowing down photosynthesis.
• an element may for example consist of a dye which will thus ensure, in the additive product according to the invention, three functions, namely a first function of decorative order, conventional in this type of product, a second function, to namely an anti-photosynthetic function, and a third function, namely an indicator showing the correct dosage or the end of the product in the metering device.
• the additive product may also comprise at least one perfume oil whose concentration in total weight of the product will be at least 2%, the latter may be especially associated with at least one volatile alcohol short molecular chain, in particular consisting of methanol, and / or ethanol and / or propanol, the concentration of which will preferably be equal to 2% by total weight of the product.
• the additive product may also contain at least two surfactants, one of them being of nonionic type.
• the additive product may contain a biocide in the form of a cationic surfactant, especially QAV, namely a quaternary ammonium.
• the present invention also relates to a pollutant treatment agent contained in a flush tank of a toilet, characterized in that it consists of:
• an additive product such as the one mentioned above, namely a liquid additive product comprising at least one organic acid whose concentration in weight is at least 30%, and whose viscosity is less than 500 mPa.s,
• the concentration in the water of the reservoir of this additive product being between 100 ppm and 1000 ppm and preferably equal to about 400 ppm.
• Figure 1 is a single curve representative of the descaling action of a next treatment agent. the invention, depending on the concentration of additive product in the tank water of a toilet flush.
• the additive product according to the invention has It also serves to ensure the maintenance of the cisterns of tanks, ie reservoirs which house mechanisms which, to remain operational, must remain free from any deposits likely to hinder or modify their functioning.
• the additive product according to the invention although it can be used with any dispensing system, is however particularly intended to be distributed by mechanical and automatic devices which, arranged in the tank of the hunt, have the particularity to deliver small doses (of the order of 2 cm 3> additive product rigorously calibrated, and this regardless of the level of water in the tank flush.
• this additive product when it is added to the water of the tank of a flush of a toilet, forms, in association with the water contained therein, a suitable treatment agent. to destroy and prevent the formation of any pollution, that is mainly tartar and microorganisms.
• FIG. 1 shows the variation of the descaling action Ad of the treatment agent as a function of its concentration C 2 in additive product.
• the descaling action represents the weight loss (in mg) of a given mass of scale for one week. It is found that the descaling action increases proportionally to the concentration to reach a maximum around 400 ppm and then decrease. There is therefore an optimum dosage of additive product at about 400 ppm.
• the specific character of the additive product that is to say a liquid product capable of being dispensed by an apparatus in the form of small volume doses, also requires that surface tension phenomena do not prevent free flow.
• the viscosity of the additive product should be at most equal to 500 mPa.s.
• the treating agent is brought into contact with mechanisms having rubber or elastomer seals and it is necessary that it not be necessary to deteriorate these elements, and mainly these joints, but on the contrary contributes to the proper maintenance of these.
• the additive product according to the invention may also comprise a perfume oil and this at a relatively high concentration rate for this type of product.
• the perfume oil at high concentration that is to say greater than about 2%, then provides a biocidal function, this biocide function fighting against the formation of microorganisms sources including odors unpleasant.
