Description

FIELD OF THE INVENTION

[0001] The present invention relates to an array of packages. The array comprises three or more different packages each comprising a different water-soluble automatic dishwashing detergent multi-compartment pouch.

BACKGROUND OF THE INVENTION

[0002] Unit dose detergent articles are particularly popular with consumers. The ease of use and consistent performance are two characteristics that consumers find desirable. For automatic dishwashing applications, unit dose detergent articles in water-soluble pouch form are very popular with consumers.

[0003] Water-soluble automatic dishwashing detergent pouches comprise an automatic dishwashing detergent composition that is enclosed by a water-soluble film. During the washing cycle, the detergent chemistry is released into the washing zone of the automatic dishwashing appliance and helps treat the dishware to be cleaned.

[0004] Consumers have many different needs when cleaning dishware in their automatic dishwashing machines. Different consumers require different performance profiles at different times when washing different loads of dishware. In addition, consumers may also require different price points at different times when washing different loads of dishware. At times, a consumer may require a greater care profile from their automatic dishwashing pouch, at other times the consumer may require a greater cleaning performance from their automatic dishwashing pouch.

[0005] Water-soluble automatic dishwashing detergent multi-compartment pouches that comprise both a liquid component and a solid component are desirable as they indicate to the consumer that the pouch has a good cleaning profile as well as a good care profile. A good care profile can include good shine performance as well as a good metal care performance.

[0006] The liquid component of the composition can be enclosed by several compartments within the pouch. The more compartments that enclose the liquid component, as well as the higher portion, by weight, of the automatic dishwashing detergent composition that is a liquid component, indicates to the consumer that the pouch has a superior care profile. Consumers that require improved care performance desire pouches having a high number of liquid-containing compartments as well as pouches that comprise a detergent composition having a high portion of liquid component compared to solid component. High portion being in relative terms because typically the composition will usually comprise more solid component that liquid component.

[0007] The fewer number of compartments that enclose the liquid component, as well as the lower portion, by weight, of the automatic dishwashing detergent composition that is a liquid component, indicates to the consumer that the pouch has a superior cleaning profile. Consumers that require improved cleaning performance desire pouches having a low number of liquid-containing compartments as well as pouches that comprise a detergent composition having a small portion of liquid component compared to solid component.

[0008] Furthermore, consumers often equate more liquid-containing compartments and a higher (relative) portion of liquid component to solid component as being an expensive water-soluble automatic dishwashing detergent multi-compartment pouch.

[0009] However, consumers may not always require a pouch that communicates good care profile, or a consumer may not always require a pouch that communicates good cleaning performance. In addition, a consumer may not always wish to use a pouch that equates to an expensive option, and instead may wish to use a pouch that equates to a lower cost option.

[0010] The present invention seeks to address this need by providing an array of packages comprising three or more different packages each comprising a different water-soluble automatic dishwashing detergent multi-compartment pouch. The array provides the consumer with at least three options that the consumer will equate to having different price points, different cleaning performance, and different care profile.

[0011] The present invention provides an array of packages comprising three or more different packages each comprising a different water-soluble automatic dishwashing detergent multi-compartment pouch, the array comprising:

(a) a first package comprising a first water-soluble automatic dishwashing detergent multi-compartment pouch, wherein the first pouch comprises a first automatic dishwashing detergent composition that is enclosed by a water-soluble film within two or more compartments, wherein the first automatic dishwashing detergent composition has a solid component and a liquid component, wherein the solid component is enclosed within one or more separate components, and wherein the liquid component is enclosed within one or two separate components;

Water-soluble film.

[0065] The water-soluble film preferably has a thickness of from 20 to 150 microns, preferably from 35 to 125 microns, or even more preferably from 50 to 110 microns, most preferably about 76 microns.

[0066] The water-soluble film is typically soluble or dispersible in water. Preferably, the film has a water-solubility of at least 50%, preferably at least 75% or even at least 95%, as measured by the method set out here after using a glass-filter with a maximum pore size of 20 microns: 5 grams ± 0.1 gram of film material is added in a pre-weighed 3L beaker and 2L ± 5ml of distilled water is added. This is stirred vigorously on a magnetic stirrer, Labline model No. 1250 or equivalent and 5 cm magnetic stirrer, set at 600 rpm, for 30 minutes at 30°C. Then, the mixture is filtered through a folded qualitative sintered-glass filter with a pore size as defined above (max. 20 micron). The water is dried off from the collected filtrate by any conventional method, and the weight of the remaining material is determined (which is the dissolved or dispersed fraction). Then, the percentage solubility (or dispersibility) can be calculated.

[0067] The water-soluble film material may be obtained by casting, blow-moulding, extrusion or blown extrusion of the polymeric material, as known in the art.

[0068] The water-soluble film preferably comprises polyvinylalcohol (PVA).

When the polyvinylalcohol in the water-soluble film is a blend of a polyvinylalcohol homopolymer and a carboxylated anionic polyvinylalcohol copolymer, the homopolymer and the anionic copolymer are present in a relative weight ratio of 90/10 to 10/90, preferably 80/20 to 20/80, more preferably 70/30 to 50/50. Without wishing to be bound by theory, the term "homopolymer" generally includes polymers having a single type of monomeric repeating unit (e.g., a polymeric chain comprising or consisting of a single monomeric repeating unit). For the case of polyvinylalcohol, the term "homopolymer" typically further includes copolymers having a distribution of vinyl alcohol monomer units and optionally vinyl acetate monomer units, depending on the degree of hydrolysis (e.g., a polymeric chain comprising or consisting of vinyl alcohol and vinyl acetate monomer units). In the case of 100% hydrolysis, a polyvinylalcohol homopolymer can include only vinyl alcohol units. Without wishing to be bound by theory, the term "copolymer" generally includes polymers having two or more types of monomeric repeating units (e.g., a polymeric chain comprising or consisting of two or more different monomeric repeating units, whether as random copolymers, block copolymers, etc.). For the particular case of polyvinylalcohol, the term "copolymer" (or "polyvinylalcohol copolymer") typically further includes copolymers having a distribution of vinyl alcohol monomer units and vinyl acetate monomer units, depending on the degree of hydrolysis, as well as at least one other type of monomeric repeating unit (e.g., a ter- (or higher) polymeric chain comprising or consisting of vinyl alcohol monomer units, vinyl acetate monomer units, and one or more other monomer units, for example anionic monomer units). In the case of 100% hydrolysis, a polyvinylalcohol copolymer can include a copolymer having vinyl alcohol units and one or more other monomer units, but no vinyl acetate units. Without wishing to be bound by theory, the term "anionic copolymer" includes copolymers having an anionic monomer unit comprising an anionic moiety. General classes of anionic monomer units which can be used for the anionic polyvinyl alcohol co-polymer include the vinyl polymerization units corresponding to monocarboxylic acid vinyl monomers, their esters and anhydrides, dicarboxylic monomers having a polymerizable double bond, their esters and anhydrides, vinyl sulfonic acid monomers, and alkali metal salts of any of the foregoing. Examples of suitable anionic monomer units include the vinyl polymerization units corresponding to vinyl anionic monomers including vinyl acetic acid, maleic acid, monoalkyl maleate, dialkyl maleate, monomethyl maleate, dimethyl maleate, maleic anyhydride, fumaric acid, monoalkyl fumarate, dialkyl fumarate, monomethyl fumarate, dimethyl fumarate, fumaric anyhydride, itaconic acid, monomethyl itaconate, dimethyl itaconate, itaconic anhydride, vinyl sulfonic acid, allyl sulfonic acid, ethylene sulfonic acid, 2-acrylamido-1-methylpropanesulfonic acid, 2-acrylamido-2-methylpropanesulfonic acid, 2-methylacrylamido-2-methylpropanesulfonic acid, 2-sufoethyl acrylate, alkali metal salts of the foregoing (e.g., sodium, potassium, or other alkali metal salts), esters of the foregoing (e.g., methyl, ethyl, or other C1-C4 or C6 alkyl esters), and combinations thereof (e.g., multiple types of anionic monomers or equivalent forms of the same anionic monomer). The anionic monomer may be one or more acrylamido methylpropanesulfonic acids (e.g., 2-acrylamido-1-methylpropanesulfonic acid, 2-acrylamido-2-methylpropanesulfonic acid, 2-methylacrylamido-2-methylpropanesulfonic acid), alkali metal salts thereof (e.g., sodium salts), and combinations thereof.

Preferably, the anionic monomer unit is present in the anionic polyvinyl alcohol copolymer in an average amount in a range of between 1 mol.% and 10 mol.%, preferably between 2 mol.% and 5 mol.%.

[0069] Preferably, the polyvinyl alcohol, and/or in case of polyvinylalcohol blends the individual polyvinylalcohol polymers, have an average viscosity (µ1) in a range of between 4 mPa.s and 30 mPa.s, preferably between 10mPa.s and 25 mPa.s, measured as a 4% polyvinyl alcohol polymer solution in demineralized water at 20°C.

[0070] The viscosity of a polyvinyl alcohol polymer is typically determined by measuring a freshly made solution using a Brookfield LV type viscometer with UL adapter as described in British Standard EN ISO 15023-2:2006 Annex E Brookfield Test method. It is international practice to state the viscosity of 4% aqueous polyvinyl alcohol solutions at 20°C. It is well known in the art that the viscosity of an aqueous water-soluble polymer solution (polyvinylalcohol or otherwise) is correlated with the weight-average molecular weight of the same polymer, and often the viscosity is used as a proxy for weight-average molecular weight. Thus, the weight-average molecular weight of the polyvinylalcohol can be in a range of 30,000 to 175,000, or 30,000 to 100,000, or 55,000 to 80,000.

[0071] Preferably, the polyvinyl alcohol, and/or in case of polyvinylalcohol blends the individual polyvinylalcohol polymers, have an average degree of hydrolysis in a range of between 75% and 99%, preferably between 80% and 95%, most preferably between 85% and 95%.

More preferably the non-aqueous plasticizer is selected from glycerol, 1,2-propanediol, dipropylene glycol, 2-methyl-1,3-propanediol, trimethylolpropane, triethyleneglycol, polyethyleneglycol, sorbitol, or a mixture thereof, most preferably selected from glycerol, sorbitol, trimethylolpropane, dipropylene glycol, and mixtures thereof. One particularly suitable plasticizer system includes a blend of glycerol, sorbitol and trimethylol propane. Another particularly suitable plasticizer system includes a blend of glycerin, dipropylene glycol, and sorbitol. Preferably, the film comprises between 5% and 50%, preferably between 10% and 40%, more preferably between 20% and 30% by weight of the film of the non-aqueous plasticizer.

[0074] Preferably, the water-soluble film comprises a surfactant. Preferably, the water-soluble film comprises a surfactant in an amount between 0.1% and 2.5%, preferably between 1% and 2% by weight of the water-soluble film.
