Definitions

  • the present invention belongs to the field of machine washing. It relates to a new washing process making it possible to optimally use the products currently available on the market in solid form, in particular powder, which are used in a washing operation, for example detergents or other special additives having activity during washing.
  • the invention also relates to a device for implementing such a method.
  • Washing is increasingly carried out in machines, using products presented in the form of powder, granules or other solid forms in particles. Washing machines are mainly drum machines but there are also so-called agitator / pulsator machines. Whatever type of machine is used, specialists know that the conditions for using such products are far from optimal. There is indeed a real problem in ensuring a uniform distribution of the particulate product and its dissolution in the washing medium located in the tank of the machine. In the following, the technical problems will be illustrated more particularly in the case of powdered detergents, but it is clear that similar problems arise with detergents presented otherwise as with any additives having activity during washing.
  • compartments or trays are provided for receiving the appropriate quantity of detergent powder before the actual washing operation.
  • the powdery active product is supposed to be entrained by the water in the tank of the machine, as the process progresses.
  • the powdered detergent is far from being completely entrained by the water, so that more or less significant residual quantities remain in the distribution tank. So the expected amount of detergent powder is not actually consumed, which affects the effectiveness of washing.
  • the washing machine tubs are always soiled with residues from previous operations. This difficulty is widely known and is the subject of numerous complaints from users.
  • the dissolution of the detergent powder particles thus come into contact with the laundry exerts an unfavorable influence on the latter.
  • the detergent particles are colored, so that the colored granules of the detergent dissolve by releasing the dye from the laundry and can then cause stains on the laundry.
  • the detergent composition contains peroxygen compounds, the corresponding granules, for example perborate, will decompose on contact with the laundry and may discolor fragile colored articles .
  • the applicant has appealed to the concept of a process according to which a device is first filled with detergent, which is then placed in the machine, with the laundry to be washed. It has, in fact, developed this concept essentially in the case of liquid detergents and, by way of reference to illustrate such a state of the art, mention may be made of patent FR-A-2563250 having as title: "Washing process of the machine washing with liquid detergent and device for its application ".
  • the detergent contained in the device gradually diffuses into the washing medium and into the laundry in the machine.
  • the device comprises a filling orifice and vents for the gradual release of the liquid within the laundry during washing.
  • such a device comprises a body capable of being filled with the desired amount of detergent, removable means for closing this body, the body or said means having holes or vents for the release of the detergent, said device being characterized in that it comprises means separating the part of the device comprising the holes or vents from the part comprising particulate detergent, said means being designed to allow the washing water to pass freely and to practically prevent the massive and uncontrolled outflow of the particulate detergent.
  • a device structure which has given very interesting practical results has the general appearance of a body of revolution which can be closed by a removable cap, which has holes allowing both the entry of water inside. of the device and also the distribution of the detergent, the device being more particularly characterized in that it comprises at least one plate mounted inside the device for separating the cap and the part of the body containing the detergent which is circular, said plate having itself at least one orifice whose surface is smaller than that of the holes or vents of the cap.
  • the perforated plate makes it possible to retain the particulate detergent in the body of the device while allowing the washing water to come to dissolve this detergent before its release in the washing machine.
  • the present invention provides a solution to these technical problems as well as to others, as will emerge from the description which follows, while fully retaining the benefits of the metering and diffusing devices which it had already proposed for particulate detergents. , in particular those forming the subject of the aforementioned patent application FR 2 614.905.
  • the invention relates to a method for washing laundry in the machine, according to which a metering and diffusing device of the reusable type is filled with a particulate product having activity during washing, this device is placed in the machine with the laundry. washing and then washing is carried out in the usual manner, characterized in that said device essentially comprises a flexible sheath in the form of a bag, extending around at least one mouth, which allows the filling of the bag with the desired quantity of product substantially corresponding to a washing operation and is closed during washing, the material constituting the bag being designed to allow the penetration of the aqueous washing medium through the bag, with a view to the gradual dissolution of the particulate product, which is located inside the bag, being gradually released during washing as a solution aqueous passing through the bag, from the inside to the outside of it.
  • the bag is made of a material capable of retaining the particulate product, without letting it pass in solid form, as well as withstanding the temperatures of washing the machine and drying.
  • the bag is permeable to water and to the washing medium, so as to allow the penetration of the aqueous washing medium into the interior of the bag as well as the diffusion and the release of an active solution of product through the bag, from the inside to the outside of it.
  • the process of the invention can be applied not only to detergents in solid form, but also to any particulate product having activity during washing, for example chosen from bleaching agents, such as agents releasing chlorine or active oxygen (peroxygen compounds), bleaching catalysts, bleaching activators, bactericides, foam regulators, brighteners, anti-redeposition agents of dirt, enzymes, softeners, agents exerting a stain-removing action grease stains or constituents which do not exert a direct action on the soiling but which can intervene in a washing process in the machine, for example the agents ensuring the protection of the organs and internal parts of the washing machine.
  • bleaching agents such as agents releasing chlorine or active oxygen (peroxygen compounds)
  • bleaching catalysts such as agents releasing chlorine or active oxygen (peroxygen compounds)
  • bleaching activators such as agents releasing chlorine or active oxygen (peroxygen compounds)
  • bactericides such as bactericides, foam regulators, brighteners, anti-redeposition agents of dirt, enzymes, softeners, agents
  • the expression "particulate product” includes all the forms of presentation of such solid products, such as powders, granules, flakes, pellets and other similar physical structures capable of being dissolved in water under normal conditions of washing.
  • the process of the invention is particularly advantageous with detergents presented under form of so-called high density particles, which are already being developed in some countries. They have advantages in packaging, transport, storage, vis-à-vis similar traditional products, because of the reduction in size they allow to obtain.
  • high-density particulate detergents tend to cause losses in the distribution tank as well as in the drainage circuits, even greater than detergents in traditional powder.
  • the ability to dissolve these new detergents is, in some cases, less than that of known products.
  • the device used according to the invention is distinguished in many aspects from certain means known from the prior art which consisted of sachets or bags which may contain a detergent or an additive useful in washing, such products may be present under particulate form in the sachet.
  • the bags or sachets of the prior art contain a predosed amount of product and cannot be reused. Their design does not allow the product to be released gradually, it being completely dispensed either immediately at the start of the washing cycle, or during it.
  • the device of the invention does not have the drawbacks of sachets or bags of the prior art.
  • the device is of the reusable kind and one can dose at will the quantity of product (detergent or any additive) thanks to the presence of the mouthpiece, which is used for filling the product.
  • the sachets or bags of the prior art must have a wall which is soluble in water or in the washing medium or else, in the case where this wall does not is not soluble in water, it is necessary to provide seals, or bonds capable of dissolving to release the products.
  • the sachets or bags are difficult to store and to market practically, because of their sensitivity to humidity.
  • the device of the invention can be recovered at the end of washing without any risk for the machine, which is entirely essential for the practical needs of users.
  • the method of the invention can be implemented with a wide variety of devices comprising a flexible bag.
  • the material of the flexible bag can be of any type, as long as it has sufficient resistance to water and to the washing medium at the temperatures used during washing as well as during drying, up to around 150 ° C. It can therefore be a woven or non-woven material produced from natural or synthetic fibers or mixtures thereof.
  • a bag formed from a flexible sheath made of pure cotton may be used either in the form of a fabric having a mesh opening of less than about 0.5 mm or in the form of a nonwoven article with openings ranging in particular from 0.5 to 0.8 mm.
  • the bag can also be produced from extruded or co-extruded films and having perforations. The dimensions of these can vary within wide limits, depending on the nature and the particle size of the particulate product.
  • perforation films of approximately 380 microns can be used.
  • the material of the bag is not necessarily a textile material.
  • the sheath can also be produced from a plastic mesh or a sheet of paper or other porous and water-resistant cellulosic material. If the material provided for the flexible bag does not in itself have sufficient resistance to water, it can be provided with a coating making it water resistant.
  • the coating may consist of a latex-based binder associated with a hydrophobic substance.
  • the exterior shape of the bag can also be very variable.
  • the bag can be a substantially cylindrical sheath extending in the extension of the mouth, when the latter is open, the diameter of the sheath then being substantially equal to that of the mouth.
  • sheaths which taper from the mouthpiece or, on the contrary, widen from it.
  • the flexible bag can have various markings corresponding to filling levels and by therefore to varying amounts of particulate products.
  • the device according to the invention has at least one mouth allowing the bag to be filled with the active product.
  • the device comprises a single mouth, the section of which may be any; circular, oval, square, rectangular and others. Good practical results have been obtained with mouthpieces of circular or oval section.
  • the mouth of the bag which is kept open for filling and closed during washing should be delimited by means serving to support the sheath of the bag and provided with removable closing members.
  • any of the arrangements can be used in known manner, which make it possible to open and close the mouth of a flexible container.
  • the mouth of the bag can be provided with a ring on which can be removably fixed a closure member, by screwing, conjugation of shapes or the like.
  • preference is given to quick opening and closing arrangements, in which it is not necessary to use a separate closure element.
  • One of the simplest arrangements consists in delimiting the mouth with lips, preferably two lips, each containing an elastic member and which can be applied or separated from one another according to the needs of the use.
  • the constituent materials of the bodies allowing the closure and the opening of the bag can be chosen without any limitation among plastic, metallic materials, wood, cardboard rendered water resistant and any other similar material. Good practical results are obtained with plastics which are easy to work with.
  • plastics which are easy to work with.
  • polyethylene and polypropylene are very suitable.
  • the shape of the support means of the flexible bag can be chosen so as to facilitate the removal of particulate product in a larger packaging, for example a barrel.
  • the support can be arranged so that its outer edge acts as a sampling trough.
  • the ring may also have surface irregularities, in relief or in hollow, allowing a good grip with the fingers.
  • fix on the support an element allowing its gripping.
  • Such an element can be permanently mounted, in which case it is preferably of small dimension, or as a variant, this element consists of a handle of larger dimension, which can be fixed on the support in a removable manner by any suitable means.
  • the method and the device of the invention are particularly suitable for the use of particulate products having a fairly slow rate of dissolution in water or else it is desired that certain constituents do not come directly into contact with the laundry in solid form.
  • the particulate products in question can be detergents for heavy washing or for delicate washing or other additives useful in washing at variable times in the cycle. It is also appropriate that the particulate product does not form a gel when water enters the bag, so that the dissolution of said product can take place gradually in contact with water. Since the device remains closed during the entire washing cycle, there is no risk of the particulate product coming into contact with the laundry.
  • the method of the invention can be applied to detergents for heavy washes having substantially the following composition: Alkyl sulphates 7-10% Fatty acid 1- 3% Sodium tripolyphosphate 18-25% Water-soluble polymers 1- 3% Sodium perborate 10-25% Sodium silicate 3- 8% Sodium sulfate 10-40% Sodium carbonate 5-10% Alcalase (enzyme) 0-2%
  • a composition which can be used as a detergent for delicate washes is also indicated by way of illustration below: Alkyl sulphates 10-20% Fatty acid 1- 3% Sodium tripolyphosphate 20-40% Sodium silicate 1- 5% Sodium sulfate 20-40% Sodium carbonate 0- 5%
  • the volume of the flexible bag must be chosen according to the dose of active product to be dispensed during washing.
  • suitable volume values for the flexible bag are approximately 250 ml to 400 ml, which makes it possible to introduce weight quantities of particulate detergent of the order of 150 250 g per wash.
  • the method of the invention which uses a metering and diffusing device with flexible bag makes it possible to use detergent compositions which currently cannot find a practical application, due to the fact that they cannot be suitably distributed from the bin or compartment fitted to the washing machine. This is already true for certain high density detergent compositions, which have already been mentioned previously. But the same observation is to be made for other detergent compositions having a poor solubility in water.
  • the method of the invention therefore makes it possible to use detergent compositions providing better washing performance, for example by reducing or even eliminating the fillers of sodium sulfate type while increasing the proportions of surfactant, for example anionic and nonionic.
  • the invention can be implemented with particulate products of very variable particle size, since those skilled in the art can choose the metering and diffusing device and in particular the material constituting the flexible bag depending on the nature of the active product.
  • the method of the invention makes it possible to dispense detergents, additives or other active washing products, available in particulate form, within the laundry even in the machine, which provides higher concentrations of detergent solution in contact with the laundry and therefore increases the performance and quality of washing.
  • the invention completely eliminates the losses of active product, in particular detergent, which occur when the metering compartment of the washing machine is used, the losses in the drain circuit of the machine being eliminated.
  • the amount of plastic used in the metering and diffusing device is very low. In some cases, it is not even necessary to use plastic to make the support for the bag. Thus the invention provides better protection of the environment because the materials constituting the device are very largely degraded in the natural environment.
  • the very small size of the dosing and diffusing device with flexible bag makes it possible to associate it in an optimal manner with the packaging of products in particles, such as detergents and other additives useful in washing. It is thus possible to use individual packages comprising larger quantities of particulate product and / or packages which themselves have a reduced bulk.
  • the device in question is very easy to handle and store, since it occupies only a very small space.
  • the invention makes it possible to use any desired quantity of product, depending on the nature of the latter. We therefore even choose the metering and diffusing device most appropriate to the characteristics of the product, a type of device then being assigned to an individual product packaging.
  • the method of the invention is still very easy to implement since the metering and diffusing device can be used directly to take off the particulate active product. Once the washing operation is complete, the device is easily retrieved from the machine and can then be reused. Even if the user forgets the device in the machine or the dryer, this presents no disadvantage either for the machine or for the laundry in a subsequent washing operation.
  • the metering and diffusing device designated by the general reference 10 in FIG. 1 essentially comprises a ring 1 made of plastic material, for example made of polypropylene and a bag 2 made of flexible material, for example made of cotton fabric or of cotton-based nonwoven .
  • the section of the ring 1 is circular, but a different section, for example oval, could also be adopted.
  • Schematically shown in 4 are the organs used for clipping or screwing a cap 3 whose inner surface 5 is provided with corresponding removable fixing means.
  • the size of the openings of the bag 2 is such that it can prevent the free passage of a particulate product, in particular a detergent, placed inside the bag, even with regard to the finest particles.
  • the flexible bag 2 had a capacity of approximately 250 ml to 400 ml, the detergent doses varying from approximately 150 to 250 g.
  • the mesh openings of the cotton fabric were less than about 0.5 mm in size. With a non-woven cotton bag, the size of the openings was about 0.5 to 0.8 mm.
  • Figure 2 is a sectional view schematically showing the mounting of the flexible bag 2 on the support ring 1.
  • the ring has an inner wall 6 connecting to an outer wall 7 providing between them an interior space 8 in which can be inserted the extreme edge 9 of the bag 2.
  • any suitable means can be used, for example an adhesive capable of withstand the temperatures used in washing machines, including those where drying is carried out, the temperatures then being able to go up to 150 ° C.
  • FIG 3 schematically shows in plan a ring 11 of structure similar to that of the ring 1 of Figures 1 and 2, the ring 11 further comprising a tongue 12 can be used as a gripping means.
  • This tongue 12 facilitates the introduction of the particulate product when the latter is taken out in a package for dosing in the bag.
  • FIG. 4 illustrates a variant in which the ring 21 can be provided with a handle 23 presented separately and which can be removably fixed at 22 by any suitable rapid fixing means, in particular by clipping or notching.
  • the opening section of the rings can have any outline.
  • devices with no sharp edges are preferred, so as to cause no damage to the laundry. This is why we prefer round or oval structures rather than structures with a square or rectangular section, even if the edges are rounded.
  • the material of the support rings is not necessarily hard, because other materials, such as paper, having a lower hardness can be used.
  • This device designated by the general reference 30 comprises a support 31 and a flexible bag 32.
