Description

Detergent container.

Technical field

The present invention relates to the sector of dishwashing, in particular refers to a container for the storage, distribution and display of a bag water-soluble multicompartmental that adapts to the dispenser of the dishwasher and releases the product in the prewash, wash cycles Main and / or subsequent rinse of the dishwasher. The bag It contains a cleaning composition that is released when it is produced The dissolution of the bag.

Background of the invention

Some consumers have observed that the doses unit detergent detergents are more attractive and comfortable because they avoid the need for the consumer to measure the product, thus creating a more precise dosage and avoiding waste of overdosing or insufficient dosage. For this reason, dishwashing detergent products in Pill form have become very popular. The products Bag-shaped detergents are also known in the art, they also have the advantage over the pads to avoid contact of the consumer's fingers with the composition for washing dishes that may contain bleach and / or other substances irritating

The process for automatic dishwashing usually involves an initial prewash cycle, a cycle of main wash and several rinse cycles. They get better results when the detergent is released at the beginning of the cycle of main wash than when the detergent is released in the cycle of prewash since this can be lost with the initial water. In washing machines for washing clothes, detergent can be place in the drum or in the dispenser, however, in the dishwasher, the detergent is usually released in the wash Main through the dispenser to avoid dissolution premature in the prewash. The amount of detergent is therefore limited by the volume of the dispenser. Dispensers vary in volume and form between the different manufacturers. In the case of loose detergent (i.e. powders, paste and liquids), the Dispenser volume is a decisive factor. In the case of unit dose forms, such as a pill, geometry and shape The dispenser also plays a very important role.

The pads can be designed to have A size and shape that suits all dishwashers. One of the disadvantages of detergent tablets is the fact that its manufacturing process requires the additional stage of the powder compaction. This stage reduces the enzymatic activity and slows the dissolution rate of the ingredients that make up the tablet, or requires the use of systems complex and expensive disintegrants or it is difficult to achieve differential dissolution of the active ingredients of the Detergent.

Some detergent ingredients used in dishwashing detergent compositions are liquid. It may be difficult or expensive to include these liquid ingredients in a solid detergent composition. Therefore determined ingredients are preferably transported and supplied to manufacturers of detergents in liquid form, requiring stages additional processing and sometimes expensive to be able to include them in a solid detergent composition. An example of These detergent ingredients is the surfactant, especially the nonionic surfactant, which is typically liquid to room temperature or is typically transported and supplied at Liquid detergent manufacturers. Another example are Organic solvents

Current methods to incorporate liquid ingredients in solid detergent compositions include the absorption of the liquid ingredient in a vehicle solid, for example, by mixing, agglomeration or pulverized Typically, solid detergent compositions they comprise only small amounts of these ingredients liquid detergents due to the difficulty and cost of incorporating These liquid ingredients in a solid detergent. Besides, the incorporation of liquid ingredients in the compositions solid detergents can affect the characteristics of dissolution of the composition (for example, as a result of the formation of the surfactant gel phases), can increase the moisture absorption by water sensitive ingredients and can also cause fluency problems. It would be advantageous to have a detergent composition that would allow different Ingredients be in their natural state, that is, liquid or solid.  This would facilitate the manufacturing process, increase the component stability and would also allow the release of liquid ingredients before or after the release of solid ingredients For example, the differential dissolution of active ingredients would be beneficial in the case of compositions of enzyme / bleach to prevent oxidation of enzymes by the bleach in the dishwashing solution. Too it would be advantageous to separate the bleach from the perfume.

Another factor that can contribute to liberation ineffective of the active substances to the wash solution, in the case of the pills, it is the need to add materials vehicle, such as porous materials capable of joining active liquid materials, binders and disintegrants. In in particular, the incorporation of surfactant liquids into detergent compositions in powder form may cause considerable processing difficulties and also the problem of a bad dissolution due to the formation of phases of gel surfactant.

There is still a need for a multicompartmental unit dose form capable of adapting to the dispensers of different types of dishwashers and that allow the simultaneous release of incompatible ingredients and Ingredients in different physical forms. There is also the need for a simplified manufacturing process for the production of a multi-compartment bag and for the production of multi-compartment bags with characteristics of improved resistance, handling and dissolution, as well as a excellent aesthetics

A container is described in WO97 / 26315 transparent colored or uncolored, like a bottle, which It contains a colored cleaning liquid. In particular, it is described a scalloped container of transparent liquid cleaning composition blue or violet color arranged in a transparent container of blue or violet color, or not colored, so that the appearance of filled container is practically transparent and neutral in color or slightly bluish green or slightly green appearance yellowish.

GB-2,235,206 describes a detergent system comprising two or more components, each of they packaged and dosed individually and where each of the components have a different color to distinguish between yes.

In EP0414462 a product of treatment for washing clothes in the form of a bag monocompartmental or multicompartmental able to release its content in the washing solution during the washing process of clothes. In D4 he also describes a multicompartmental bag; without However, as in EP0414462, nothing is mentioned at all of containers that allow to see through it for the storage of These little bags.

Summary of the invention

The present invention provides a container display comprising a container that allows viewing through it, for example a cardboard container or a bottle transparent or translucent that contains a plurality of doses unit detergent products in a multiplicity of groups visually or otherwise sensory different.

Preferably the unit doses are multi-compartment bags, possibly each compartment by itself visually distinct or otherwise different from the rest of the compartments in an individual bag. In a preferred embodiment, the groups of bags are different in As for color. In the case of multicompartmental bags, such as At least one group of bags has a compartment that is visually distinctive, for example, in terms of color, of the corresponding compartment in one or more other groups of bags. Preferably in said embodiments, all groups of bags they have at least one "common" compartment, that is, whose aspect is the same between groups. Preferably the compartment visually distinctive contains a liquid, a gel or paste; he Common compartment contains a powder or a pill. The bags are can be arranged in any form in the package, or randomly or in an order, for example, the provisions suitable that include layers where each bag comprises as at least one compartment of a different color than any of the rest of the remaining bag compartments on it cap. The container can be made of plastic or any other material, provided that the material is sufficiently Strong to protect the bags during transportation. This type of packaging is very useful also because the user does not need to open the container to see how many bags are left, since the bags of Different colors are very easy to identify from the outside. Alternatively, the package may have an outer container that do not allow to see through, perhaps with signs or illustrations that they represent the visually distinctive content of the package.

In another embodiment different groups of bags They contain different perfumes. Perfumes can be perfumes associated with a color, for example, lemon-scented yellow, pink With the smell of strawberry, blue with the smell of the sea.

The bag preferably has a volume of 5 to 70 ml, preferably 15 to 60 ml, more preferably 18 to 57 ml, and a longitudinal / transverse dimensional relationship in the range from 2: 1 to 1: 8, preferably from 1: 1 to 1: 4. The dimension longitudinal is defined as the maximum height of the bag when the bag rests on one of the bases that has the maximum surface when the compartments of the bag are superimposed on a longitudinal direction, that is, one over another and with a load static of approximately 2 kg. The transversal dimension is defined as the maximum width of the bag in a perpendicular plane to the longitudinal direction in the same conditions. These dimensions are suitable to fit the dispensers of the Most dishwashers. Although the shape of the bag can vary a lot in order to maximize the available volume, the Preferred bags have a base as similar as possible to the profile of most dispensers, that is generally rectangular.

In one embodiment, the plurality of Water-soluble bag compartments is in a relationship generally superimposed and the bag comprises exterior walls upper and lower generally opposite, side walls to edge mode that make up the sides of the bag, and one or more internal partition walls that separate the different compartments with each other, and where each of said walls upper and lower exterior and side wall by way of edge are shaped by thermoforming, vacuum forming or A combination of them.

The bag, when used herein it can be of any form and material that is suitable for contain the product before use, e.g. eg, without allowing release of bag compositions before putting on Contact the bagged composition with water. The exact realization it will depend for example on the type and quantity of the compositions in the bag, the required characteristics of the bag to maintain, protect and dispense or release the compositions, the number of compartments in the bag.

In the present invention bags are preferred water-soluble having a compartment comprising a liquid composition and another compartment comprising a powder composition or densified powder composition. During the manufacturing of the liquid compartment typically forms a Air bubble. This air bubble can reduce the understandability of the bag and therefore the ease of Closing the dispenser after placing the bag inside. It has been discovered that the ease of closure increases when the ratio between the diameter of the air bubble and the lateral dimension Maximum bag profile is approximately 1: 5 a approximately 1: 2. Preferably, the bubble has a diameter from about 9 to about 16 mm. The dimension of the Bubble can be controlled by process parameters.

During use, the water-soluble bag is usually placed inside the dishwasher dispenser and is released during the main cycle of the dishwashing process. However, some dishwasher dispensers are not completely water-tight, mainly for two reasons, or the dispenser has some openings that allow water to enter or the dispenser is sealed with a rubber band that can deform over time due at the high temperature of the dishwashing process. Water entering the dispenser can cause premature leakage of part of the contents of the bag, which is lost at the end of the prewash. This problem is especially acute in the case of bags comprising liquid compositions having a low viscosity where a considerable amount of the product can be lost before the main wash cycle. The problem can be solved by causing the bag or at least the liquid compartment thereof to be of a film-shaped material that is designed to survive the prewash cycle and release the contents of the bag on or after the start of the bag cycle. main wash In European dishwashers, prewashing is usually carried out in a cold water cycle (approximately 20ºC or less) without detergent and with a duration of approximately 10 to
15 min.

Preferably the film-shaped material it has a water solubility according to the test defined below in the present invention of less than about 50%, more preferably less than about 20% and especially less of approximately 5% in cold water conditions (20ºC or less) when exposed to water for at least 10 minutes, preferably at least 15 minutes and a water solubility of at least about 50%, more preferably at least about 75% and especially at least about 95% in hot water conditions (30 ° C or higher, preferably 40 ° C or higher) when exposed to water for approximately 5 minutes and preferably when exposed to water for approximately 3 minutes Such materials in the form of a film referred to herein are practically insoluble in cold water although soluble in hot water. Sometimes this is abbreviated simply as "hot water soluble."

50 grams ± 0.1 gram of material are added bag-shaped to a heavy 400 ml beaker previously and 245 ml ± 1 ml of distilled water are added. This it is maintained at the desired temperature by using a water bath and stir vigorously on a magnetic stirrer set to 63 rad / s (600 rpm), for the desired time. TO then the mixture is filtered through a glass filter Qualitative sintered folding with a maximum pore size of 20 \ mum. Water is removed from the filtrate collected by any conventional method and the weight of the remaining material is determined (the which is the fraction dissolved or dispersed). Next it is calculated % solubility or dispersibility.

Water insoluble commercial films Cold and hot water soluble include BP26 marketed by Aicello, L10 and L15 marketed by Aquafilm, VF-M and VM-S marketed by Kuraray and E-2060 marketed by Monosol.

In a preferred embodiment a bag multicompartmental comprises a first compartment comprising a liquid composition and a second compartment comprising a powder composition or densified powder composition. Preferably, the liquid compartment is made of a hot water-soluble material as described above in this memory and the powder or powder compartment densified is made of a cold water-soluble material, it is that is, a material that is soluble to a degree of at least 50%, preferably at least 75%, more preferably at least 95%, in weight under cold water conditions (20ºC or less) when exposed to water for about 5 minutes and preferably when expose to water for about 3 minutes. Due to the way in which European dishwashers work (these are filled with cold water and cold water is heated by a heater), the compartment made of water-soluble material needs more time to dissolve that the compartment made of a material water soluble. This form of bag allows a delayed release of the liquid composition providing the optimized use of the detergent composition Preferably, the liquid composition it comprises detergent enzyme, this being advantageous from the point in view of the stability during enzyme storage, separating the enzyme from the bleach and the materials highly alkalines contained in the powder or powder composition densified In addition, the compartment containing liquid (practically insoluble in cold water and soluble in hot water) it will need more time to dissolve or disintegrate than the compartment containing the solid (cold water soluble), minimizing the negative interaction in the wash solution between bleach and enzymes and between the surfactant and enzymes and providing better removal of protein stains and pre-treatment benefits in the later stages of the dishwashing

The compartments of the bags containing solid compositions, in particular compositions comprising oxygen bleaching bleach, they are usually perforated with in order to allow the escape of any oxygen formed. Without However, holes formed by drilling can also allow the escape of perfumes or the exit of bad smells. By For example, surfactants often have a smell unpleasant associated and when such bags are packaged within a secondary container, the smell of unpleasant surfactant can be concentrate in the upper space of the container and free each time The user opens the container. This problem can be avoided. including the surfactant in the liquid composition, since the compartments that contain the liquid must be free of drilled holes Thus, according to another embodiment, the composition Liquid comprises a surfactant. Another advantage of having the surfactant in the liquid phase is to avoid problems loading the surfactant on the solid material. Another advantage is that the surfactant is released with a certain delay with respect to the solid composition, allowing better performance of the bleach and enzymes, which can be seen adversely affected by the interaction between the surfactant and the surfaces of crockery, cutlery and glassware.

Preferably the perfume is introduced into the solid composition, piercing and allowing the release of perfume before using the product in the dishwasher.

The films practically insoluble in water cold and hot water soluble have a moisture and content of relatively low plasticizer, so the film would require an important time and temperature in order to seal them by heat sealing. These requirements may cause damage to the film, so that for example the holes drilled in the point where the film is stretched over the mold can cause a spill, especially problematic in the case of bags containing liquid. Therefore, it is preferred that compartments made of basically insoluble films in cold water and soluble in hot water and housing liquids are Seal using solvent, which partially hydrates the film before sealing, reducing time and temperature required for sealing, generating solid joints and avoiding hole formation. In the preferred embodiment of bags with differential solubility that have a compartment that comprises a liquid composition and another compartment comprising a powder composition, in which the liquid compartment is made of material basically insoluble in cold and soluble water in hot water and the powder compartment is made of material that is soluble in cold water, it is preferred that the Liquid compartment is sealed by solvent sealing while the liquid compartment is sealed with the Powder compartment by heat sealing.

The bag can also be placed outside the dispenser, for example, in the cutlery basket, in a net or dishwasher door. In this case, it is preferred that The entire bag is made of a film-shaped material, as for example, the one described above herein, which protects the contents of the bag until at least the beginning of the main wash cycle

Although the nature of bagged products It is such that they dissolve or disperse easily in water, it can be prefer that disintegrating agents as effervescent sources, water swellable polymers or clays are present in the own bag, and / or the product contained in it, in particular effervescent sources based on an acid and a source of carbonate. Suitable acids include carboxylic acids. organic such as fumaric acid, maleic acid, malic acid, citric acid; and suitable carbonate sources include salts sodium carbonate, bicarbonate and percarbonate. Preferred Levels of the disintegration aids or sources of effervescence or both are 0.05% to 15%, even 0.2% to 10% or even 0.3 to 5%, by weight of the total bagged composition.
