COMPOSITIONS IN BAG

TECHNICAL FIELD

The present invention relates to compositions in a bag having a compartment containing different components attached in different regions and a process for the manufacture of these compositions in a bag.

BACKGROUND OF THE INVENTION

Currently cleaning compositions come in many forms of products, such as granules, liquids and tablets, each having its advantages and disadvantages.

Recently, tablets have gained renewed interest, because they are user-friendly and easy to dose ('unit dose') and additionally have an additional advantage in that they allow incompatible ingredients to be incorporated separately from each other, for example in different layers. This can reduce the contact area of ​​these incompatible materials and thus reduce the occurrence of any reaction between such materials.

However, to make the tablets stable in storage and to avoid breakage of the tablets during handling, the ingredients have to be compressed together and binding agents are generally needed to ensure that the tablets do not break. This can reduce its solubility and dispersibility, which is undesirable for consumers and also from an operational point of view.

Thus, alternative modes or better ways are required to provide easy-to-handle unit dose products whereby different ingredients can be readily present apart from each other (for example to reduce intimate contact and to improve ingredient stability. incompatible) that do not produce dust or break.

The inventors have now discovered an improved way of providing improved products to solve the aforementioned problems, specifically by specifically incorporating a product into a bag, so that the aforementioned requirements are met.

Detergent bags as such are known in the art that are useful for providing unit dose compositions and for separating ingredients from one another. For example, US Patent 5,224,601 describes packaging made from different compartments for different materials. However, this type of structure and also other bags that are known in the art have their problems and often require a complicated manufacturing route and a relatively large amount of sheet material.

The inventors have now discovered improved pouched particulate compositions which are such that intimate contact with different components thereof is reduced, without the need to compact them to the extent of tablets without the need for difficult structures, such as separate multiple compartments, to separate different ingredients from each other. In the products of the invention, the different components of the composition are specifically packed tightly in different regions of one and the same compartment or bag, so that they are substantially immobilized or attached and remain in this way during handling and storage. However, because the components are still in powder or granular form and are not glued to one another as in tablets, the dispersion of the composition comprising these components in water is very rapid. In this way, improved storage stability of eg incompatible ingredients such as enzymes and bleach is achieved with a minimum of bag material and a very good product supply and performance.

Additionally, improved procedures are provided to form the composition in a bag, such that the components in the regions are held fixed or immobilized.

BRIEF DESCRIPTION OF THE INVENTION

The present invention provides a composition in a bag, the composition comprises two or more particulate components, and the bag comprises one or more compartments that disintegrate in water, are soluble in water or dispersed in water, according to which at least two of the Components are present in one and the same compartment and each forms one forms a fixed region in the aforementioned compartment.

In particular, the composition in a bag of the invention is obtained by a process that comprises the steps of:

a) obtaining an open bag comprising an open compartment;

b) Introducing a particulate component before at least one other particulate component in the open compartment and / or introducing a particulate component in a different part of the open component than at least one other particulate component; and ic) subsequently closing the open compartment so as to obtain a bag with a compartment (soluble in water or dispersible in water) comprising fixed regions of the aforementioned particulate components.

The components are so tightly packed that the regions are fixed, while the composition still flows freely (which can be seen when the bag is removed). This provides the advantages outlined above.

Typically this can be accomplished by overfilling the open compartment, using stretchable and preferably elastic material for the compartment, or using heat shrinkable material for the compartment or filling and closing the open compartment under reduced pressure or still vacuum.

The composition in the bag is preferably such that the volumetric density of the composition after closing the compartment is 5% to 45% or even 35%, preferably 5% to 30% or even 10% to 25% higher than the average of the volumetric density of the components before introducing into the compartment.

Preferably, the bag as a whole is soluble in water. Preferably the composition is a cleaning composition or fabric care composition or composition that is added during rinsing.

The invention also provides processes for making the inventive bag compositions, for example by the method described above and preferred procedures as claimed and described later in the present invention. A preferred procedure is such that it results in an uneven thickness of the compartment material, which can provide very rapid release of produced into the water, or can help control the release time of the different components to the wash water.

DETAILED DESCRIPTION OF THE INVENTION

Compositions and components thereof

The composition of the invention is present in a bag and in the present invention is also referred to as a bag composition. The composition comprises at least two different particulate components. Generally, the particulate component is a powder or granules, extrudate, or flakes.

When used in the present invention, 'different' means that one component has at least one different chemical property, for example at least one different ingredient, than the other component or components, or one component has at least one physical property. different from the other component or components. Typically, one component comprises one or more oxidizing ingredients and another component comprises one or more reducing ingredients or oxidizable ingredients. Examples are described later in the present invention.

The particulate components are present in the compartment such that they form fixed or immobilized regions within this compartment.

Fixation of the regions limits the direct contact of the components of the composition with each other, preferably only to the area where the regions touch, without the need for separate compartment structures for the components.

Typically, regions are formed by introducing a particulate component into an open compartment before another particulate component, so that layers of components are obtained. Alternatively, or additionally, this can be formed by introducing a component into a different part of the open compartment.

Typically, the regions are fixed and immobilized by tightly packing the components together and ensuring that there is substantially no free headspace within the compartment that allows the powders to move. Typically, the tight packaging is such that the volumetric density of the components after closing the compartment and thus the volumetric density of the compositions in the bag is 5% to 45%, preferably 35%, preferably 5%, or even

10% to 30% or even 25% or it may be preferred that this is 8% to 20% or even 15% higher than the average volumetric density of the components before incorporating into the bag.

The volumetric density of a component before it is incorporated into the bag composition can be determined using the Repour Cup method, as described in ISO 3424- 1975-E. The average volumetric density of the components before Incorporating into the compartment is first determined by measuring the volumetric density of each component using ISO 3423. Then, a weighted average is calculated based on the weight percentage of the component in the Final composition. For example, a bag consists of a compartment with a composition consisting of two components A and B. Component A is present in 40% by weight of the final composition. Component B is present in 60% by weight of the final composition. Component A has a Repour Cup volumetric density (as measured by ISO 3424) of 500 g / l. Component B has a volumetric density of 800 g / l (as measured by ISO 3424). The average volumetric density of the composition before being incorporated into the bag is therefore ((500 x 0.4) + (800 x 0.6)) = 680g / l.

The average volumetric density of the packaged composition, after closing the compartment, can be determined by a volume displacement method. A container with a wide neck and a collection arm is filled with a solvent of known density, which should not affect the material of the compartment or bag, up to the level of the collection arm. The bag composition to be tested is accurately weighed and then dipped into the liquid, for example by using a piece of thin metal wire. The amount of liquid that is displaced by the bagged composition in the liquid leaves the container through the arm and the arm is carefully collected and weighed. The volume of this displaced liquid is easily calculated from the known weight and density of the liquid. Density and volume replacement due to matter! bag (instead of the composition within it) can be measured or calculated. This is subtracted from the volume replacement of the liquid as measured in the aforementioned test. Then the density of the composition can be calculated. (The errors associated with the thin wire used to immerse the bag are minor and are not taken into account.) Depending on the material of the bag or compartment, a suitable liquid can be selected. For example, for water soluble material such as PVA, the preferred liquid is glycerol. This is because the bags may contain microscopic holes in the film as a result of stretching. Using a viscous solvent such as glycerol will minimize any errors due to liquid infiltration into the bag. Nonionic surfactants such as Neodol 235 are also useful.

The formation of fixed regions and tight packing can be performed by increasing the packing efficiency and reducing the space between the component particles, for example by vibrating the components in the form of the open compartment, allowing the component particles to settle for a period of time, modestly increasing pressure, for example by applying a pressure of up to 20MPa, preferably up to 10MPa or more preferably up to 5MPa or even up to 2MPa, in case of using any pressure, provided that the components and composition flow freely.

The volumetric density of the component can be achieved through a compaction step. Typically, the particulate component is first placed in the open compartment, and then pressure is exerted on the aforementioned component causing the volumetric density of the aforementioned component to increase from 5% to 50%, preferably from 10% or 15% or 20%, and preferably 45% or 40%, or 35% or 30% of the original volumetric density of the component before the compaction step.

Pressure can be exerted in the form of a solid body, which is typically of a size and shape that is capable of fitting into the opening of the open compartment. The solid body is capable of applying pressure to the aforementioned component. Preferably, the solid body applies a pressure of up to 20MPa, preferably up to 10MPa or more preferably up to 5MPa or even up to 2MPa, to the particulate component.

To ensure tight packing of the components in the compartments, the particulate components are for example introduced into the open compartment (preferred procedures of which are described below) so that the open compartment is preferably almost completely filled, typically so that at least 95% of the volume of that form of open compartment, preferably at least 98% or even at least 100% of the open compartment form is filled, prior to closing the aforementioned open compartment form, or it may still be preferred that the form be overfilled with the components, i.e. , that the volume of the components is more than 100% of the volume of the form, preferably more than 105% or more preferably more than 110% or even more preferably more than 115%. With this, closing the open compartment which is 95% full by volume or more ensures that there is only very limited headspace in the compartment after closing and thus very limited movement of components in those compartments, i.e. , that the regions formed by the components are fixed.

The composition in the bag in the present invention can be obtained, for example, by a process comprising:

a) obtaining an open bag comprising an open compartment;

b) Introducing a particulate component before at least one other particulate component in the open compartment and / or introducing a particulate component in a different part of the open component than at least one other particulate component; and

c) subsequently closing the open compartment so as to obtain a bag with a compartment comprising fixed regions of the aforementioned particulate components.

In a preferred procedure, step c) of the aforementioned process can be carried out under reduced pressure, below atmospheric pressure, preferably by applying a vacuum, so that after filling and closing under reduced pressure or vacuum, a tightly packed compartment.

The compartment preferably is formed of a stretchable material, preferably a film, preferably an elastic film, as described later in the present invention. This is particularly useful in case the open compartment is fully filled or still overfilled, and closed by a stretch film, so that the part of the film that is used to close the compartment is stretched and / or the film is stretched from the open compartment, tight packing and fixed regions are obtained. The use of an elastic material is then preferred, to ensure that the tight packing remains throughout the tempo.

Alternatively, the open compartment is rigid and in step b) the components are inserted into the open compartment so that at least 100%, preferably at least 105% of the open compartment is occupied by the components, and the open compartment is then preferably it is closed with a stretchable material.

The formation of fixed regions and tight packing can also be achieved by using a shrinkable material for the compartment, whereby the surface area is reduced during or after closure of the open compartment by shrinking the material. A suitable material is for example a heat shrink material.

The formation of the open compartment or open shape can be accomplished by any known means. Preferred open shapes are manufactured by introducing a material to form the compartment over a mold, then a vacuum is applied to the mold, so that the material takes the shape of the mold, also referred to as vacuum forming. Another preferred method is thermoforming to make the material take the shape of the mold.

The introduction of the components can be carried out by any suitable method to introduce materials that flow freely into the molds.

Even though the compartment comprises at least two particulate components, a liquid component can be added. It may be preferred that a particulate first component is first introduced into the open compartment, then sprayed on a small amount of liquid, typically 0.5-10% or even 1% to 5% by weight of the first component, preferably water, and subsequently The second particulate component is added. In this way, the regions can be even more fixed or immobilized.

The component comprises at least an amount of at least one particulate compound, but typically the component comprises at least two particulate compounds, preferably fully mixed to form the component. Because the component in the bag compartment is fixed in fixed regions, the interaction between the different components is reduced. This allows the incorporation into a composition of incompatible ingredients, by separating these predetermined regions.

The composition in the present invention can be any particulate composition, in particular any free-flowing granular or powder composition to be supplied to, and active in, water.

Preferred compositions are beverages, edible compositions, pharmaceutical compositions, personal care compositions, cleaning compositions, fabric care or conditioner compositions; more preferably, the compositions in the present invention are cleaning compositions or fabric care compositions, preferably hard surface compositions, more preferably laundry or dish washing compositions, including detergents, pretreatment or soaking compositions, or fabric conditioners. , and other compositions that are added in the rinse.

When used in cleaning compositions the component may contain any active cleaning ingredients. In particular, active ingredients such as surfactants, chelating agents, detergency builders, enzymes, perfumes, bleaches, bleach activators, softeners, fabric conditioners, antibacterial agents, sources of effervescence, brighteners, photobleaches, are preferred. Fabric care compositions preferably comprise one or more softening agents, such as quaternary ammonium compounds and / or softening clays, and preferably additional agents such as anti-wrinkle aids, perfumes, chelating agents, fabric integrity polymers.

Generally, water is present at a level of 0% to 10%, more preferably 0.2% to 5% or even 0.2% to 3%, or even 0.5% to 2% by weight of the compartment, preferably of the bag.

Typically, the composition comprises such an amount of a cleaning composition that one or a multitude of the bagged compositions is or is sufficient for one wash.

Although the nature of the bag composition is such that it readily dissolves or disperses in water, it may be preferred that disintegrating agents such as effervescence sources, polymers or clays that swell with water be present in the same material as the composition. bag or compartment, and / or in the composition that is inside, in particular sources of effervescence based on an acid or a carbonate source. Suitable acids include organic carboxylic acids such as fumaric acid, maleic acid, methyl acid, citric acid; Suitable carbonate sources include sodium carbonate, bicarbonate, percarbonate salts.

Preferred levels for disintegration aids or effervescence sources or both are 0.05% to 15% or even 0.2% to 10% or even

0.3 to 5% by weight of the composition in the bag.

In particular, for cleaning compositions, it is advantageous for one component to comprise at least one or more enzymes and another component to comprise a peroxygen bleach such as a percarbonate salt. The component containing the peroxygen bleach is then enzyme free, while the component comprising the enzyme may comprise a bleach activator, but no peroxygen bleach.

It is also advantageous to include the bleaching agents, but in particular the peroxygen bleach in a different component than any hygroscopic materials or anhydrous or hydratable materials including excessively dried materials, such as aluminosilicates, salts or anhydride acids.

When the bagged compositions are such that they have visually differential top and bottom sides, and then, when the regions are in the form of layers, it may also be advantageous to include non-gelling detergents of the bottom layer, such as water soluble salts and acids, including for example effervescent salts and acids such as carbonate salts and organic carboxylic acids such as citric acid, and in a higher or higher layer potentially gelling ingredients such as anionic and nonionic surfactants. Then, it is advantageous to include any peroxygen bleach in the bottom layer and any enzymes in the top layer, if required. It has been found that when such a bagged composition is introduced into the wash via a dispensing device, in particular a dispensing compartment, a faster and more complete delivery to the wash is achieved.

It may be advantageous to include any surfactant and bleaching agent within the compartment so that it is supplied prior to any softening agents in the compartment or bag.

It may still be possible that some or all of the components are not pregranulated, such as agglomerates, spray dried, extruded, before being incorporated into the compartment, that the component is a mixture of dry mixed powdered ingredients or still raw materials. It is preferred that for example less than 60% or even less than 40% or even less than 20% of the component be free flowing pregranulated granules.

Furthermore, it has been found to be advantageous for cleaning operation, when the cleaning compositions in the present invention or the material of the compartment or bag, preferably both the composition and the aforementioned material, comprise one or more chelating agents, in particular EDDS or EDTA or HEDP.

It has also been found that the presence of high levels of certain compartment or bag dissolved materials having free hydroxy groups in the wash water may have a negative effect on the removal of clay stains under certain wash conditions. Therefore, it is not only advantageous to use as little compartment material as possible and thus preferably to use a bag with only one compartment, but it has also been found to be advantageous to incorporate into the composition or the bag material a polyalkoxylated compound. , preferably a polyalkoxylated alcohol, preferably having an average carbon chain length of alcohol of 11 to 24, preferably 12 to 20 or even 14 to 18, and an average degree of alkoxylation of at least 20 or even at least 40 or even at least 70. Highly preferred are 0.1% to 8%, or even 0.5 to 5%, or even 0.8% to 3% by weight of the bag composition of such a compound; highly preferred is TAE8O.

The composition may also comprise liquid compounds or gels or compound solutions, for example liquid or gel nonionic surfactant, liquid fabric softening agents, preferably then comprised in a separate compartment of the bag.

Another preferred ingredient is a perhydrate bleach, such as percarbonate salts, particularly sodium salts, and / or a bleach precursor or organic peroxyacid activator compound. When the bag or compartment is formed of a material with free hydroxy groups, such as PVA, the preferred bleaching agent comprises a percarbonate salt and is preferably free of any perborate salts or borate salts. Borates and percarbonates have been found to interact with these hydroxy-containing materials and may reduce dissolution of the materials and also that this may result in reduced performance.

Preferred activators or precursors are the alkyl percarboxylic precursor compounds of the imida type including the alkylenediamines N-, N, N¹N¹ tetra acylated wherein the alkylene group contains 1 to 6 carbon atoms, particularly those compounds in which the alkylene group contains 1, 2 and 6 carbon atoms such as tetraacetyl ethylenediamine (TAED), 3,5,5-tri-methyl sodium hexanoyloxybenzenesulfonate (iso-NOBS), sodium nonanoyloxybenzenesulfonate (NOBS, sodium acetoxybenzenesulfonate (ABS) and pentaacetyl glucose, but also precursors of substituted alkyl peroxyacid amide amide.

Humlcola sp., Thermomvces sp. or Pseudomonas sp. Including Pseudomonas pseudoalcallglenes or Pseudomonas fluorescens. The lipase from genetically or chemically modified mutations of these strains is also useful. A preferred lipase is derived from Pseudomonas pseudoalcaligenes, which is described in European Patent Granted EP-B0218272.

Another preferred lipase in the present invention is obtained by donating the Humicola lanuginosa gene and expressing the gene in

Aspergillus oryza, as a host, as described in European Patent Application EP-A-0258 068, which is commercially available from Novo Industries NS, Bagsvaerd, Denmark, under the tradename Lipolase. This lipase is also described in US Patent 4,810,414,

Huge-Jensen et ah, issued March 7, 1989.

Anionic surfactants are also preferred, including salts (including, for example, sodium, potassium, ammonium, and substituted ammonium salts such as mono-, di, and triethanolamine salts) of the sulfate, sulfonate, carboxylate, and sarcosinate anionic surfactant. , preferably linear or branched alkyl benzenesulfonate, alkyl sulfates and alkyl ethoxysulfates, isethionates, N-acyl taurates, acidic amides of methyl tauride grades, alkyl succinates and sulfosuccinates, sulfosuccinate monoesters (especially monoesters C₁₂-C₁₈ saturated and unsaturated), sulfosuccinate diesters (especially C-diesters₆-C₁₄ saturated and unsaturated), N-acyl sarcosinates. It is highly preferred that when anionic surfactants are present, at least one alkyl sulfate surfactant is present, preferably a branched alkyl sulfate surfactant, preferably at a level of 1% to 20% or even 15% by weight of the component or composition.

In a preferred embodiment of the present invention, the composition in the bag comprises a first particulate component that forms a first fixed region in the compartment of the bag and comprises perfume, and a second particulate component that forms a second fixed region in the bag compartment comprises an item selected from the group consisting of bleach, nonionic surfactant, polyethylene glycol having a molecular weight of 4000 or more, enzyme, and combinations of these. Typically, the second component is perfume-free. In this preferred embodiment of the present invention, the perfume in the composition is more stable since it is contained in a separate fixed layer to the aforementioned ingredients causing perfume instability. This allows the perfume to remain stable in the composition comprising the perfume destabilizing ingredient.

Bag, and compartments) of the same

The bag in the present invention has a closed structure, made of materials described in the present invention, that encloses a volumetric space that comprises the composition. Thus, the bag can have any shape and material that is suitable for holding the composition before use, eg, without allowing the composition of the bag to be released before contacting the bag composition with water. The exact execution will depend on for example the type and amount of the composition in the bag, the number of compartments in the bag, the characteristics that are required of the bag to hold, protect and supply or release the compositions.

The bag may be of a size that conveniently contains or a unit dose amount of the composition in the present invention, suitable for the required operation, for example when the composition is a detergent composition, this may be an amount sufficient for a wash, or only a partial dose, to allow the consumer greater flexibility to vary the amount used, for example depending on the size and / or degree of soiling of the washing load.

Preferably, the bag composition is formed in a mold with a round or flat bottom and circular walls. Thus, it is also preferred that the bag composition be a spheroid or more preferably a cylinder shape.

The bag has one or more compartments, of which at least one holds two different particulate components. In a preferred embodiment, all of the particulate components are present in one and the same compartment of the bag; it may be preferred that the bag has only one compartment. This reduces the material that is required to form the compartment and bag. However, it may be preferred that one or more additional compartments for liquid component are present in addition to the compartment comprising the two or more particulate components.

The bag compartment has a closed structure, made of materials described in the present invention, which encloses a volumetric space that comprises the components. Thus, the compartment is suitable for holding the particulate components prior to use, eg, without allowing the components to be released from the compartment before contacting the bagged composition with water. The compartment can be of any shape, depending on the nature of the compartment material, the nature of the components or composition, the intended use, the quantity of the components, etc. In case more than one compartment is present, the compartments are linked or connected to each other by any means, for example heat seal or damp seal, bonded by any known glue material, examples of which are described below in the present invention.

Preferably, the compartment or preferably the bag as a whole is made of a material that is stretchable, as set forth in the present invention. This for example facilitates the closure of the open compartment form which is filled by more than 95% by volume or even 100% or is still overfilled as described above. Furthermore, the material is preferably elastic, to ensure that tight packing and fixation of the regions remain during handling, eg, to ensure that (additional) headspace cannot form after compartment closure. .

Preferred stretchable materials have a maximum degree of stretch of at least 150%, preferably at least 200%, more preferably at least 400% as determined by comparing the original length of a piece of material with the length of this piece. of material immediately before breakage due to stretching, when a force of at least 1 Newton is applied.

Preferably, the material is such that it has a degree of stretch as before, when a force of at least 2 Newton, or even at least 3 Newton, is used. Preferably, it has this degree of stretch when a force of the aforementioned lower limits is used, but not greater than 20 Newton, or even 12 Newton, or even 8 Newton. For example, a piece of film with a length of 10 cm and a width of 1 cm and a thickness of 40 microns is stretched longitudinally with increased tension, to the point of breaking. The degree of extension can be determined and calculated just before the break by continuously measuring the length and degree of stretch. For example, this piece of film with an original length of 10 cm can be stretched with a force of 9.2 Newton to 52 cm immediately before the break, and then has a maximum degree of stretch of 520%.

The force to stretch such a piece of film (10 cm x 1 cm x 40 microns) to a degree of 200% preferably should be at least 1 Newton, preferably at least 2 Newton, more preferably at least 2.5 or still 3 Newton, and preferably not more than 20 Newton, preferably less than 12 Newton, more preferably less than 8 Newton. This in particular ensures that the elastic force remaining in the film after formation is high enough to immobilize the powders within the bag, but not so high that the film cannot be pulled into a vacuum mold of reasonable depth. .

As is clear from the definition in the present invention, stretchable material is defined by a degree of stretch that is measured when it is not present as a closed pouch. However, as stated above, the material preferably stretches when the compartment is formed. This can be seen for example by printing a grid on the material, eg film, before stretching, then a compartment with the component of this material is formed with the grid. You can see that the grid squares are elongated and thus stretched.

The elasticity of the stretch material of the compartment, and preferably the bag as a whole, can be defined as elasticity recovery '. This can be determined by stretching the material for example to a 200% extension, as discussed above, and measuring the length of the material after releasing the stretching force. For example, a piece of film 10 cm long and 1 cm wide and 40 microns thick is stretched longitudinally to 20 cm (200% extension) with a force of 2.8 Newton (as indicated above) and then withdraw the force. The film immediately returns to a length of 12 cm, which means an 80% elastic recovery.

The elasticity of the bag material mentioned in the present invention is the elasticity at the time of making the bag. Prolonged stretching, for example that typically occurs during bag storage, will reduce the elasticity of the bag material due to plastic bleed. It is preferred that at the time of manufacturing the bag or compartment therefrom, the compartment material has an elasticity such that the elastic recovery is from 20% to 100%, more preferably from 50% to 60% or even more preferably from 75 % or even 80% to 100%.

Thus, the material of the compartment and preferably the entire bag is stretched during formation and / or closure of the compartment or bag, so that the resulting bag composition has a compartment or bag that is at least partially stretched. Typically and preferably, the degree of stretch is non-uniform throughout the compartment or bag, due to the forming and closing procedure. For example, when a film is placed in a mold and an open compartment is formed by vacuum forming (and then filled with the components and then closed) the part of the film at the bottom of the mold, which is furthest from The closing points will stretch more than at the top. Preferably, the elastic material that is furthest from the hole, eg, the material at the bottom of the mold, will stretch more and be thinner than the material closest to the hole, eg, at the top of the mold. Therefore it may be preferred that the component to be supplied to the water first is comprised in the lower layer of the compartment, and a component to be supplied to the water at a later stage is comprised in a subsequent layer, closer to the top of the compartment. Alternatively, or additionally, it may be preferred that the least moisture sensitive component is comprised in the lower layer of the compartment and a more moisture sensitive component is comprised in a subsequent or higher layer.

Another advantage of using stretch material and also preferably elastic material is that the stretching action, when the compartment shape is formed and / or when the compartment is closed, stretches the material unevenly, resulting in a compartment and bag that it has an uneven thickness. This allows control of the dissolution / disintegration of the water soluble bags in the present invention, and for example the sequential release of the components of the composition in the bag to water.

Preferably, the material is stretched such that the variation in thickness in the bag compartment or bag formed of the stretched material is 10 to 1000%, preferably 20% to 600%, or even 40% to 500% or even 60% to 400%. This can be measured by any method, for example by using an appropriate micrometer.

Bag and Compartment Material

Preferably, the composition is a composition to be supplied to the water and thus, the bag and its compartment (s) are designed such that at least one or more of the components is released into, or immediately then, from the moment of adding to the water. Thus it is preferred that the compartment and preferably the bag as a whole comprise material that is water dispersible and more preferably water soluble. It is especially preferred that at least one component is supplied to the water within 3 minutes, preferably even within minutes, even before 1 minute after contacting the bag composition with the water.

The preferred water dispersible material in the present invention has a dispersibility of at least 50%, preferably at least 75% or even at least 95%, as measured by the method set forth in the present invention using a glass filter and a maximum pore size of 50 microns.

More preferably the material is soluble in water and has a solubility of at least 50%, preferably at least 75%, or even at least 95%, as measured by the method set forth in the present invention using a glass filter with a maximum pore size of 20 microns, specifically:

Gravimetric method to determine the water solubility or water dispersibility of the compartment and / or bag material: 10 grams ± 0.1 gram of material is added in a 400 ml bottle, from which the weight has been determined, and 245 ml is added ± 1 ml of distilled water. This is shaken vigorously on a magnetic stirrer at 600 rpm, for 30 minutes.

The mixture is then filtered through a qualitative sintered glass filter folded with the pore sizes as defined above (maximum 20 or 50 microns). The water is dried from the collected filtrate by any conventional method, and the weight of the remaining polymer (which is the dissolved or dispersed fraction) is determined. Then, the percentage of solubility or dispensability can be calculated.

Preferred materials are polymeric materials, preferably polymers that are formed into a film or sheet. The material in the form of a film can be obtained for example by casting, blow molding, extrusion, or blow extrusion of the polymeric material, as is known in the art.

Preferred polymers, copolymers, or derivatives thereof are selected from polyvinyl alcohols, polyvinylpyrrolidone, polyalkylene oxides, acrylamide, acrylic acid, cellulose (modified), cellulose ethers or esters (modified), cellulose amides, polyvinyl acetates, polycarboxylic acids, and their salts, polyamino acids or peptides, polyamides, polyacrylamide, maleic / acrylic acid copolymers, polysaccharides including starch and gelatin, natural gums such as xanthan and carrageenan. More preferably the polymer is selected from polyacrylates and acrylate copolymers soluble in water, methyl cellulose, sodium carboxymethyl cellulose, dextrin, ethyl cellulose, hydroxyethyl cellulose, hydroxypropyl methyl cellulose, maltodextrin, polymethyl acrylates, polyvinyl polyvinyl polyvinyl alcohols, polyvinyl alcohols, polyvinyl polyvinyl alcohols

The polymer can have any weighted average molecular weight, preferably from about 1,000 to 1,000,000, or even from 10,000 to 300,000, or even from 15,000 to 200,000 or even from 20,000 to 150,000.

Polymer blends can also be used. This can be particularly advantageous for controlling the mechanical and / or dissolution properties of the compartment or bag, depending on the application of these and the needs required. For example, it may be preferred that a mixture of polymers is present in the compartment material, while a polymeric material has a higher solubility in water than another polymeric material, and / or a polymeric material has a higher mechanical strength than another polymeric material. . It may be preferred that a mixture of polymers are used, which have different weighted average molecular weights, for example a mixture of PVA (or a copolymer thereof) and / or HPMC of a weighted average molecular weight of 10,000-40,000, preferably about 20,000, and PVA (or copolymer thereof) and / or HPMC with a weight average molecular weight of about 100,000 to 300,000, preferably, about 150,000.

Also useful are polymer blend compositions, for example comprising a mixture of hydrolytically degradable and water soluble polymers such as polylactide and polyvinyl alcohol, which is accomplished by mixing polylactide and polyvinyl alcohol, typically comprising 1-35% by weight of polylactide and approximately 65% ​​to 99% by weight of polyvinyl alcohol, in case the material is to be soluble in water.

It may be preferred that the polymer present in the compartment material is 60% to 98% hydrolyzed, preferably 80% to 90%, to improve dissolution of the material.

Most preferred are materials that are water soluble elastic and stretchable materials comprising PVA polymer having properties such as PVA films that are marketed under the M8630 trade reference as marketed by Chris-Craft Industrial Products of Gary, Indiana, USES.

Preferably, the level of a type polymer (e.g., commercial blend) in the film material, for example PVA polymer, is at least 60% by weight of the material or film, preferably at least 60% or even by at least 70% or even at least 80 or 90%. The top tier is up to 100%, but typically 99% or even 98% by weight.

The material in the present invention may comprise additive ingredients other than the polymer or polymer material. For example, it may be advantageous to add plasticizers, eg, glycerol, ethylene glycol, diethylene glycol, propylene glycol, sorbitol, and mixtures thereof, additional water, disintegration aids. It may be useful when the bag composition is a detergent composition, that the bag or the compartment material itself comprises a detergent additive to be supplied to the wash water, for example organic polymeric soil release agents, dispersants, transfer inhibitors of the dye.

The material in the form of a film can be coated, preferably only on one side, with any coating method and with any coating agent, depending on the required properties; for example, it may be advantageous to coat the film so that the compartment or bag or composition within is more storage stable and / or less sensitive to moisture and / or acts as an improved moisture barrier.

A very useful way is to coat the material or film on one side with a coating that stops dissolution of the film, before the formation of the compartment and of this suit before stretching of the material or film. Then, by stretching the material or film, the coating is also stretched, resulting in cracks in the coating and / or uneven distribution of the coating over the material and thus over the compartment. This then still ensures stability against moisture during storage, while the presence of cracks or uneven distribution still ensures the required dissolution in use. Accordingly, it is possible to manufacture a bag composition that is resistant to handling with wet fingers when picked up from the sides but will still release the product quickly when immersed in water due to film breakage at the thinnest points.

Any coating material can be used, particularly useful are hydrophobic coatings, or polymers with low water solubility, lower than previously defined in the present invention.

The compartment material may be a shrink material, so that the surface area can be reduced during or after the closure of the open compartment by shrinking the material.

Preferably, the open compartment is closed with a piece of the same material as the material of the open compartment. The closure material and thus preferably also the open compartment material or shape material, preferably is thermoplastic so that it can be closed by heat sealing. Alternatively, a thermoplastic coating can be provided, either on top of all material or just in the areas where the seals are to be formed. Sealing can also be accomplished by solvent welding or wet soldering. Suitable heat sealable materials include polyvinyl alcohol, polyvinyl acetate, polyvinyl pyrrolidone, polyethylene oxide, acrylic resins, and mixtures thereof, in particular polyvinyl alcohols.

EXAMPLES ¹⁵

EXAMPLE 1

A piece of Chris-Craft M-8630 film, 38 microns thick, is placed on top of a mold and fixed in its proper place. The mold consists of a cylindrical shape with a diameter of 45 mm and a depth of 25 mm. A 1mm thick layer of rubber remains around the edges of the mold. The mold has some holes in the mold material to allow a vacuum to be applied.

A vacuum is applied to pull the film into the mold and the film is pulled to an exact level with the inner surface of the mold. 20 g of a detergent powder mixture comprising percarbonate salt and water-soluble salts and organic acids, typically carbonate, citric acid and / or citrate salts, enzymes, bleach activator and surfactant are poured into the mold. This powder mixture has a volumetric density of 860 g / l before being poured into the mold. Then 20 g of a powdered detergent mixture is poured into the mold. This powder mix has a volumetric density of 90 g / l before being poured into the mold.

The mold fills between 95% to 105%.

Then a sheet of the same film M-8630 15 is placed on top of the top of the mold with the powder and the first layer of film is sealed by applying a flat metal ring piece with an internal diameter of 46 mm and heated Metal under moderate pressure on the rubber ring on the edge of the mold, to heat seal the two pieces of film together. The metal ring is typically heated to a temperature of 140 20 146 ° C and applied for up to 5 seconds. The film is stretched during this procedure.

The volumetric density of the bag composition was then tested by the method described above and found to be

1020 g / l.

The bags that are manufactured using the aforementioned method, released the product when immersed in 5 liters of water to

10 ° C in less than 10 seconds.

EXAMPLE 2

A two-layer bag composition containing a detergent composition is prepared as follows.

A piece of 38 micron film is placed on a mold of the following dimensions and fixed in its proper place so that the film is at an exact level with the top of the mold.

The circular diameter of the bottom of the mold is 28mm; the circular diameter of the top of the mold is 37mm; the depth of the mold is mm.

A vacuum is applied to the film so that it is pulled into the mold and is at an exact level with the sides of the mold. 11.75 grams of the following component (A) is poured into the film in the mold.

Component A

Enzymes

2.5 %

Agglomerates Surfactants 41.6%

Everfescent particle

6.9 %

Antifoam Particle

7.2 %

Sodium carbonate

28.8 %

Bleach activators

13.0%

This component has a volumetric density of 725 g / l.

Then 2.5 grams of sodium percarbonate are added on top of component A. The sodium percarbonate has a volumetric density of 1005 g / l. Then a second layer of 38-micron M-8630 film is placed over the powder and mold and sealed to the first film layer using a heat seal procedure as described in Example 1.

The average volumetric density of the composition in the bag before being incorporated into the bag is therefore 774 g / l. After bagging, the volumetric density of the composition was measured at 951 g / l - an increase of 23%.

EXAMPLE 3

The procedure as described in Example 1 is used to make a two layer pouch composition consisting of 36 grams of sodium percarbonate and 4 grams of Termamyl 120 (as supplied by Novo Industries). Sodium percarbonate forms the bottom layer and the enzyme the top layer.

Then a single layer pouch composition is made according to the procedure described in Example 1 but with the enzymes and percarbonate homogeneously mixed with each other.

Both bagged compositions have an increase in density of 18%. In both situations the film on the bag is stretched.

Both types of bagged compositions are then stored in high temperature and humidity conditions (90 ° F, 80% relative humidity) without any type of outer covering or packaging protection. Samples were taken after 48 hours of storage and 96 hours and the activity of the enzymes in the two products were compared with each other. The activity of the enzyme in the single layer bag after 48 hours is only 30% of the activity of the enzyme in the double layer bag composition; the activity of the enzyme in the single layer bag after 96 hours is only 20% of the activity of the enzyme in the single layer bag composition.

This shows increased storage stability by using fixed regions or layers to separate incompatible materials.
