Definitions

  • the present invention relates to the field of washing and cleaning machine laundry.
  • European patent application No. 85400652.5 published under No. 0151549, in the name of the applicant, describes an original method of washing laundry in the machine with a liquid detergent.
  • a device is used containing a liquid detergent and comprising non-blocked vents. This device is placed with the laundry to be washed in the drum of the machine and the machine is started up allowing the washing cycle to run, the detergent thus progressively passing through the laundry and the washing bath as soon as the machine is started. on the way.
  • a predetermined quantity of liquid detergent is poured into the device, which has for this purpose a filling orifice and, at the end of the washing, the device is recovered which can be reused.
  • Such a device comprises at least one filling orifice and vents for the gradual release of the liquid within the laundry during washing.
  • the device comprises a body and an attached assembly, which is intended for filling and / or diffusing the liquid.
  • Such an assembly can be permanently mounted on the body or on the contrary be removable.
  • Such an assembly may include a central filling orifice and vents distributed around its periphery.
  • the filling orifice has the form of a chimney plunging inside the body. It will also be noted that an advantageous arrangement in practice consists in giving the device an essentially spherical shape. However, this form is in no way limiting and it is possible, for example, to implement other forms of revolution.
  • the device is filled with liquid detergent and it is thus placed filled in the drum of the machine, where the laundry is already located, the liquid detergent contained in the device gradually diffusing during washing in the medium. washing and in the laundry.
  • a controlled predissolution of the detergent is carried out in the device, physically preventing the detergent from leave the device in particulate form, in a massive and uncontrolled manner, while allowing the washing liquid to penetrate inside the device, so as to allow the gradual release of the pre-dissolved detergent within the medium containing the laundry in washing course.
  • a metering and diffusing device suitable for implementing such a method comprises a body capable of being filled with the desired quantity of particulate detergent, removable means for closing off this body, the body or said means having holes or vents for detergent release. Means separate the part of the device comprising the holes or vents from the part comprising the particulate detergent, these means being designed to allow the washing water to pass freely and to practically prevent the massive and uncontrolled exit of the particulate detergent.
  • the device has the general shape of a body of revolution which can be closed by a removable cap. It comprises at least one plate mounted inside the device for separating the cap and the part of the body containing the particulate detergent, said plate itself having at least one orifice whose surface is smaller than that of the holes or vents of the cap. .
  • the Applicant has continued its work in the general field of machine washing technique, the subject of its aforementioned European patent application 0151549. It was desirable, in fact, to have a simple process, which can be implemented with inexpensive devices, for simultaneously solving several technical problems which arise with the detergent compositions currently available on the market.
  • the first problem to be solved is to allow the user to have a method and a device for adapting the washing conditions to the state of soiling of the laundry, thereby providing "à la carte washing". This problem is general and it exists as well for liquid detergent compositions as for the compositions in particulate form.
  • a complementary problem results from the fact that it is desirable to wash the laundry with a detergent composition, the constituents of which exert their activity at the optimum time, as well as intervening in the washing process, for example to ensure a protective role for parts of the washing machine, only to fulfill their specific function during washing, which is the case for example with enzymes, softeners, agents which have a stain-removing action on grease stains, peroxygen compounds, bleaching catalysts , bleach activators, bactericides, foam regulators, optical brighteners and other similar constituents with specific functions.
  • Such constituents must be available at determined instants of the washing cycle and the technical problem to be solved is to find a simple and practical method for presenting these constituents so as to make them available for the washing process according to a predetermined and optimal sequence.
  • the invention provides a solution to the problems which have just been mentioned, whatever the type of detergent used, and this by taking advantage of the currently existing devices which are for example described in the aforementioned European patent application 0152350 and which have proven in practice, very suitable for the implementation of the general washing technique described in particular in the European patent application 0151549 mentioned above.
  • the subject of the invention is an improved machine washing process, in which a device is used comprising non-blocked vents and containing a detergent, this device is placed. with the laundry to be washed in the drum of the machine and the machine is started by letting the washing cycle take place, said process being characterized in that a detergent composition is used, some of the constituents of which are separated, in that at least one of said components is introduced into the device and in that at least one other of said components is associated separately with said device, so that, during washing, all of the components diffuse in the laundry and the washing bath .
  • the method is applicable to detergent compositions in which certain constituents have a specific mode of action on soiling. It can also be used in the case where certain constituents have insufficient compatibility with others within the detergent composition.
  • Nonlimiting examples of constituents which, in the process according to the invention, can be separated from the detergent composition proper are: bleaching agents, such as agents releasing chlorine or active oxygen (peroxygen compound), brightening agents, anti-redeposition agents of dirt, enzymes, softeners, agents exerting a stain-removing action of grease stains.
  • bleaching agents such as agents releasing chlorine or active oxygen (peroxygen compound)
  • brightening agents such as agents releasing chlorine or active oxygen (peroxygen compound)
  • the fact of associating with the device at least one component having a specific mode of action on dirt means as well that such a component is made integral with the device as soon as it is put in place. machine and from the start of the washing cycle or that such a constituent is presented in a separate form to produce its effects during the washing cycle, in combination with the other constituents contained in the device.
  • the constituents presented in separate form can be contained in bags or sachets, for example by individual dose, in a nonwoven material or on the contrary in a material soluble in the washing bath (for example in polyvinyl alcohol PVA).
  • These constituents can also be capsules or tablets or lozenges soluble in the washing bath, as well as granules, sheets, for example nonwoven, impregnated or coated with active ingredients, or materials having the consistency of a dough.
  • the actual detergent composition is in liquid or granular form and is supplied individually to the user.
  • the latter also has specific action products or constituents which are offered to him separately and, for example, have characteristic tones or colors for each of them, so that the user can, according to the indications given to him , adapt the formulation of the detergent composition to the precise need for washing, depending on the state of soiling of the laundry.
  • the problem of insufficient incompatibility of certain constituents of the detergent composition can be solved.
  • the method of the invention can be implemented with a very simple device or container, for example of the general type described in the European patent application published under No. 0152359 or in the aforementioned French patent application No. 8707413.
  • the device or container may include housings, for example in its outer periphery, capable of receiving the separate constituents in any of the forms which have been previously mentioned.
  • a container comprising a body of revolution and an assembly, removable or not, with a central filling orifice having a chimney shape, and vents distributed at its periphery
  • the constituents of said composition which are intended to be associated with the container, and which are for example presented in the form of a sachet of nonwoven material or soluble in the bath of washing.
  • a container comprising a double chimney, one allowing filling with the actual detergent composition and the other serving for placing the bags, which then have a specific housing.
  • the chimney or chimneys in question can be left free at their upper part or on the contrary comprise a clip-on cover or a movable cover, for example with a hinge, so as to enclose the constituents in their housings and to let them diffuse through the vents of the container. , together with the rest of the detergent composition.
  • these separate constituents can also be presented in a different form, for example a liquid or a gel.
  • these separate constituents of the actual detergent composition can be placed in the container in a particular housing.
  • the container can be supplied to the user with a housing thus filled in advance, in which case it suffices to fill the container with the detergent and to clear the opening of this housing, to allow the diffusion of the detergent as well as of the constituent already put in place.
  • the invention provides a simple and effective solution to the technical problems mentioned at the start of this specification.
  • certain methods of washing laundry in the machine have involved the use of a machine capable of removing the separate ingredients of a detergent formulation from separate tanks.
  • This technical solution is extremely complicated, since it is not only necessary to modify the structure of the machines but to provide expensive programming equipment which comes into operation as the washing cycle proceeds.
  • the process of the invention takes advantage of all the advantages of simplicity and efficiency of the general washing technique which is the subject of European patent application 0151549.
  • the advantages of this technique namely better washing efficiency and elimination of detergent losses in the machine's drain circuit, the invention adds great flexibility in the washing conditions, the user being able to carry out "à la carte washing", depending on the nature and condition of the laundry to be washed and soiling to be removed.
  • the invention also relates to the packaging of containers of washing products for a washing machine, intended to be introduced into said machine.
  • Washing machines for washing clothes or dishes include at least one compartment intended to receive a washing product, washing machines for washing linen generally even comprising several compartments for receiving various products for washing and / or softening and / or purifying and which are hereinafter generally referred to as "detergents".
  • the compartments are designed to empty into the machine during the washing cycle.
  • Each product is in the form of a powder or a liquid and it is the user himself who fills the corresponding compartment, from a packaging or a container of bulk product.
  • such a detergent container for a washing machine intended to be introduced into said machine, contains a determined dose of product for a washing cycle.
  • the container is already ready for use, which avoids, in particular, any manipulation of product and any dosing problem.
  • a shape that is particularly well suited for a container according to the invention is the spherical shape.
  • the containers according to the invention can be packaged in any way.
  • an original packaging is advantageously used which is remarkable in that it groups together a plurality of containers, containing products which are distinct by the nature of the articles to be washed and / or the function of the product, and which differ from each other by different brands and / or colors.
  • the devices which will be described are of the general type which is the subject of the European patent application published under No. 0152359. They include, as illustrated in particular in Figure 1, a body 1 of generally spherical shape and an attached assembly 2 to which the body 1 is connected by a flat surface 4 extending radially and extended by a cylindrical surface 5 extending upwards.
  • the attached assembly 2 comprises an upper part 6 in the form of a bowl providing a central opening 7.
  • the wall of the bowl 6 has peripheral perforations 8.
  • the bowl 6 is extended downwards by a cylindrical part 9 in the form of a plunging chimney inside the device 1, which is intended to serve as a container for the detergent composition.
  • the attached assembly 2 also has parts 10, projecting outwards and at the periphery, which come to bear on the surface 4 of the body 1 and essentially serve as gripping means.
  • the process of the invention can advantageously be implemented with this type of device, which makes it possible to combine certain separate constituents of the basic detergent composition, which is introduced into the body 1.
  • a number of tablets containing ingredients or constituents having a specific function for washing are placed inside the chimney 9.
  • the inner surface of the chimney 9 may have annular projections 13 making it possible to provide them with housings where the tablets 12 are housed respectively.
  • the chimney is limited by a wall 14 situated at a level intermediate of its height, which makes it possible not to be forced to push a tablet into the chimney to its lowest level.
  • the chimney 9 has been illustrated as having longitudinal lateral openings, which are usual in devices of this type already used. However, for the needs of the invention, it may be advantageous to provide a chimney with full walls, so that the detergent composition, for example liquid, introduced into the body 1 does not immediately come into contact with the tablets housed in the fireplace.
  • the detergent composition for example liquid
  • the drawing of Figures 1 and 2 illustrates tablets housed in the chimney, but the same provisions could be applied with constituents presented in the form of capsules or any other structure having sufficient strength to be inserted and maintained in the chimney.
  • FIG. 3 shows a cover 16 movable around a hinge 18 and capable of being manipulated by a ring 17.
  • This cover can be useful if the material of the bag 15 is a non-woven fabric which does not dissolve in the washing bath, in which case it is better to avoid that, at the end of it, the bag escapes the device and could possibly cause damage to the mechanical parts of the washing machine.
  • the cover 16 is folded down at the top of the chimney, so that it is closed.
  • the chimney 9 presents, as it is usual, longitudinal openings 19 also making it possible to bring the sachet into contact with the washing liquid, to ensure the diffusion of the constituent that it contains. If the bag 15 is formed of a water-soluble material such as polyvinyl alcohol, it is sufficient to place it in the chimney which then does not need to be sealed at its upper part.
  • Figures 4 to 6 illustrate an alternative embodiment according to which tablets of constituents having a specific function for washing are placed not in the chimney as indicated in Figures 1 to 3 but in the bowl 6 of the set 2 attached on the body 1.
  • a part 20 is provided which is pressed inside the bowl by enclosing the tablets.
  • This part 20 is shown in perspective in Figure 6. We see that it has skirts 21, 22 having the shape of cylindrical walls which extend vertically to match the vertical walls of the bowl 6, but only over a limited area thereof, while passages or orifices 23, 24, 25 are also provided to then allow the diffusion of the active products in the washing bath.
  • the part 20 also has at its upper part two recesses 26, facing each other, which facilitate gripping of this part.
  • Figure 4 clearly shows the situation of the device when the part 20 is put in place and pressed inside the bowl 6. This same arrangement appears in section in Figure 5, where we also see two tablets 12 housed in bowl 6.
  • Figure 7 illustrates a tablet that can be used in any of the aforementioned devices, as well as in those which will be illustrated below.
  • This type of tablet can be obtained directly by compacting a substance having an activity in a washing process, for example a mineral compound such as a peroxygen compound, in particular sodium perborate.
