Description

FIELD OF THE INVENTION

[0001] Consumer product comprising a container and at least one water-soluble unit dose article.

BACKGROUND OF THE INVENTION

[0002] Water-soluble unit dose articles are liked by consumers due to their convenience and ease of use. Water-soluble unit dose articles comprise a water-soluble film shaped to form at least one internal compartment which houses a single use dose of a detergent. Upon addition of the water-soluble unit dose article to water, the water-soluble film dissolves and/or disintegrates releasing the detergent into the surrounding water to produce a wash liquor.

[0003] Such water-soluble unit dose articles have historically been stored and transported in rigid or flexible plastic containers. Consumers purchase containers comprising a plurality of water-soluble unit dose articles. The containers are shipped from the place of manufacture to supermarkets and once purchased are stored in consumers' homes. Recently such water-soluble unit dose articles have been made commercially available in containers made from biodegradable material such as paper-based containers.

[0004] Water-soluble unit dose articles stored in containers made from biodegradable material may be exposed to an environment of higher moisture and higher humidity compared to plastic containers because such containers have higher moisture vapour transfer rates than plastic containers. Exposure to higher moisture and humidity may lead to problems including discolouration of the liquid detergent composition, or changes in the properties of the water-soluble film. Changes in the properties of the water-soluble film may make the water-soluble unit dose articles stickier, with greater tendency to stick to each other or to the inside wall of the container. Changes in the properties of the water-soluble film may make any ink used for printed information on the water-soluble unit dose articles more likely to smear and to become illegible. Changes in the properties of the water-soluble film may impact the integrity of a barrier layer applied on the container inside wall when the film comes into contact with the barrier layer.

SUMMARY OF THE INVENTION

[0005] The present invention relates to a consumer product comprising at least one water-soluble unit dose article and a container wherein the at least one water-soluble unit dose article comprises at least one water-soluble film orientated to create at least one unit dose internal compartment. The at least one unit dose internal compartment comprises a liquid detergent composition. The container comprises a container body which comprises a first compartment in which the at least one water-soluble unit dose article is contained. The first compartment is accessible through a first opening. The container further comprises a container cover, wherein the container cover is positioned so that it prevents access through the first opening when the container is not in use, but is moveable to allow access to the container body when the container is in use. The container body comprises an interior surface and an exterior surface, wherein the interior surface faces the first compartment. At least part of the interior surface of the container body is constructed from paper-based material. The paper-based material has an interior surface which is covered by a barrier layer so that the water-soluble film of at least one unit dose article directly contacts the barrier layer on the internal surface of the paper-based material.

[0021] The film may be opaque, transparent or translucent. The film may comprise a printed area. The printed area may be on the inside or on the outside or on both the inside and on the outside of the water-soluble film. In some embodiments the film may comprise a phthalocyanine based pigment. Such a pigment is used to print on to the film. A preferred pigment includes SpectraRAY^® F UVDB354 commercially available from Sun Chemical and is a phthalocyanine based pigment. It is referred to as CAS 147-14-8.

[0022] The area of print may be achieved using standard techniques, such as flexographic printing or inkjet printing.

[0023] The film may comprise an aversive agent, for example a bittering agent. Suitable bittering agents include, but are not limited to, naringin, sucrose octaacetate, quinine hydrochloride, denatonium benzoate, or mixtures thereof. Any suitable level of aversive agent may be used in the film. Suitable levels include, but are not limited to, 1 to 5000ppm, or even 100 to 2500ppm, or even 250 to 2000ppm.

Container

[0025] The consumer product comprises a paper-based container. The container comprises a container body, wherein the container body comprises a first compartment in which the at least one water-soluble unit dose article is contained. Preferably the first compartment comprises at least two water-soluble unit dose articles. The first compartment may comprise between 1 and 80 water-soluble unit dose articles, or even between 1 and 60 water-soluble unit dose articles, or even between 1 and 40 water-soluble unit dose articles, or even between 1 and 20 water-soluble unit dose articles. The volume of the first compartment may be between 500ml and 5000ml, preferably between 800ml and 4000ml.

[0026] The first compartment is accessible through a first opening. Those skilled in the art will be aware of a suitable size for the first opening. Without wishing to be bound by theory, the first opening should be of sufficient size to retrieve at least a single water-soluble unit dose article at a time. Alternatively, the first opening may be shaped to allow the unit dose articles to be poured out from the container. Therefore, it should be dimensioned to be big enough for at least a single unit dose article to fit through the first opening. Preferably, the first opening should be big enough for a user to fit their hand through to retrieve at least one water-soluble unit dose article.

[0027] The container comprises a container cover to cover the first compartment of the container body. Preferably the container cover is a lid or hood. The container cover is positioned so that it prevents access through the first opening when the container is not in use, but is moveable to allow access to the first opening when the container is in use. The container body and the container cover are able to move relative to one another to allow the container cover to block entry to the first opening when not in use, but then allow access to the first opening when in use. Without wishing to be bound by theory, the user controls the movement of the container body and container cover relative to one another to achieve this.

[0028] The movement of the container body and the container cover relative to one another can be achieved via any suitable means. Those skilled in the art will be aware of suitable means. The container cover may act as a lid or hood to the container body. The lid may be hinged to the container body.Preferably the container cover acts as a hood to the container body and can be completely separated from the container body. Preferably, the container cover comprises a top wall and at least one side wall, and the container body comprises a base wall and the first opening, wherein the first opening is opposite to the base wall and the base wall and the first opening are connected by at least one side wall. In the closed position the at least one side wall of the container cover overlaps at least partially over the one side wall of the container body. In other words, the container cover acts as a hood positioning over the container body and so blocking access to the first opening.

[0029] The container preferably further comprises a locking means. The locking means comprises a first locking component on the container body and a second locking component on the container cover. The first locking component engages the second locking component to prevent sufficient movement of the container cover relative to the container body to allow access to the first opening, until the first locking component and second locking component are disengaged from one another by a user. Those skilled in the art will be aware of suitable locking means to achieve this. A preferred locking means is where the first locking component comprises a tab and the second locking component comprises an abutment against which the tab abuts when in the closed position. The abutment may simply comprise a surface against which the tab abuts. Alternatively, the abutment comprises a slot or pocket capable of receiving the tab when in the locked position. Preferably, the first locking component is a tab that protrudes from the exterior surface of the container body and the container cover comprises an abutment against which the first locking tab is able to releasably engage.

[0030] The container may comprise more than one locking means. The container may comprise two locking means. The locking means may be orientated to be opposite one another on the container, such that the consumer can hold the container and using a thumb and a finger to open both locking means simultaneously. Preferably, wherein the locking means are opposite to one another the container is of an appropriate dimension to allow the user, especially an adult user, to grip the container with one hand and simultaneously open both locking means using the thumb and a finger of the other hand. When the container comprises at least two locking means, preferably the two locking means are spaced apart by a distance of between 70mm and 150mm, more preferably between 80mm and 120mm. Without wishing to be bound by theory such distance allows for the adult human handspan to ergonomically fit around the container to allow simultaneous disengagement of the two locking means.

[0031] Preferably both locking means comprise a first locking component on the container body and a second locking component on the container cover. Preferably the first locking means and second locking means both comprise tabs on the container body and abutments on the container cover.

[0032] The container body comprises an interior surface and an exterior surface, wherein the interior surface faces the internal compartment. At least part of the interior surface of the container body is constructed from paper-based material and the paper-based material comprises a barrier layer on the interior surface so that the water-soluble film of the at least one unit dose article either directly contacts the barrier layer of the internal surface.

[0033] By paper-based material, we herein mean a material comprising paper. Without wishing to be bound by theory, by 'paper' we herein mean a material made from a cellulose-based pulp. Preferably, the paper-based material comprises paper, cardboard, or a mixture thereof, wherein preferably, cardboard comprises paper-board, corrugated fibre-board, or a mixture thereof. The interior surface of the container body is constructed from a paper-based material having a barrier layer on the interior surface. More preferably, the whole of the container body is constructed from a paper-based material having a barrier layer on the interior surface.

[0034] The container cover comprises an interior surface and an exterior surface. At least part of the interior surface and at least part of the exterior surface of the container cover is constructed from a paper-based material having a barrier layer on the interior surface, preferably the entire interior surface of the container cover is constructed from a paper-based material having a barrier layer on the interior surface, even more preferably, the entire container cover is constructed from a paper-based material having a barrier layer on the interior surface.

[0035] The paper-based material may be a laminate comprising paper, cardboard, or a mixture thereof, wherein preferably, cardboard comprises paper-board, corrugated fibre-board, or a mixture thereof, and at least a second material. Wherein the paper-based material is a laminate, then the internal surface of the container body and preferably the internal surface of the container cover comprises paper, cardboard, or a mixture thereof, wherein preferably, cardboard comprises paper-board, corrugated fibre-board, or a mixture thereof, and preferably the external surface of the container body, external surface of the container cover or a mixture thereof comprises the second material. Alternatively, the second material might also be laminated in-between two paper-based material layers.

[0036] Without wishing to be bound by theory, paper-board comprises fibres running in the fibre direction, wherein the fibre direction should be understood to be the direction along the longest dimension of the fibres. Preferably, the tab comprises a fold which runs perpendicular to the fibre direction. Such folding of the tab results in the tab being capable of returning to its original position, in other words having a memory property to allow it to spring back. This is preferably so that it can re-engage efficiently with the second locking component on subsequent use.

[0037] Those skilled in the art will be aware of suitable materials for coating or barrier. The paper-based packaging may comprise a barrier material for improved performance such as providing humidity control and are usually applied on the paper-based surface on one or both sides, depending on the end use.

Preferably, the paper-based laminate comprises greater than 50%, preferably greater than 85%, and more preferably greater than 95% by weight of the laminate of fibre-based materials. Preferably, the plastic material if present has a thickness of between 10 micrometers and 40 micrometers, more preferably between 10 micrometers and 35 micrometers. Preferably the paper-based laminate comprises less than 5% by weight of the laminate of plastic material. Most preferably the paper based material is free of such a plastic material.

[0039] A widespread of alternative barrier application types exist, including dispersion barrier in which the surface is finished with a water-based dispersion technology turning the board liquid and grease resistant during its use while it breaks down in a paper recycling process hence still enabling a high yield of recovered paper fibers when products are recycled, green PE (polyethylene) made of renewable, plant-based raw material, PE Coating hence polyolefin barriers including LDPE and HDPE polymers, biodegradable coating including tailor-made polymers including biopolymers which can be produced from natural crops or from fossil raw materials, PET coating, PP coating, or a mixture thereof. However, it is preferred that the barrier material comprises less than 5% wt. more preferably less than 1% and preferably substantially zero PE, PP or PET.

[0040] In a preferred embodiment the barrier comprises a water-based dispersion. Water-based dispersion barrier coatings protect the packaging from external and internal influences, including humidity impacts. Preferably, the interior surface of the first part of the container comprising the water-soluble unit dose articles comprises such a water-based dispersion barrier. Preferably also the exterior surface of the lid or hood part comprises such a water-based dispersion barrier. Preferably, the lid or hood component comprises less than 1% wt. of the barrier material, more preferably wherein the barrier material is a water-based dispersion barrier. More preferably, the dispersion barrier component comprises a thermoplastic elastomer (TPE). Said TPE is preferably dispersed in the barrier component. Contrary to some alternative barrier components, TPE dispersion barriers have the advantage they can be applied as one layer, rather than requiring a multi-layer application process. Examples of such multi-layer alternative barrier components include those commercially available from Weilburger under the Senolith^® brand. Examples are also described in WO 2018/069413. Such water-based dispersion barrier materials may be applied as a wet layer primarily. The dispersion is preferably an aqueous dispersion, in particular a PTFE dispersion, perfluoroalkoxy (PFA) polymer dispersion, and/or fluorinated ethylene-propylene (FEP), copolymer of hexafluoropropylene, these polymers typically being present in a range of from 40% to 60% of the water-based dispersion. The water-based dispersion can further comprise a resin, typically in a range of from 3% to 8% of the water-based dispersion, in order to improve adhesion to a substrate. Exemplary suitable resins include polyamideimide, polyphenylene sulfide (PPS), polyether sulfone (PES), polyether ether ketone (PEEK), silicone resin and/or polysulfone.

The outerlayer may be on the interior or the exterior side of the paper-based material or on both sides of the paper-based material. Preferably the paper-based material comprises a bleached and un-bleached layer on opposing sides. Preferably, the lid or hood comprises a bleached layer on the exterior side and an unbleached layer on the interior side. Preferably, this outermost layer further comprises printed parts. Preferably, the bleached layer also comprises a barrier material as described above. Bleaching has been found to facilitate printing, coating or barrier layer application. More preferably, the interior surface comprises an unbleached layer and most preferably is not treated with a barrier material. Preferably, the first part of the container comprising the water-soluble unit-dose articles comprises a bleached layer on the interior side, hence physically in contact with the water-soluble unit dose articles, and an unbleached layer on the exterior side. Preferably, this bleached layer also comprises a barrier material as described above. The lid or hood having a non-bleached interior surface and the first part of the container comprising the water-soluble unit dose articles having a non-bleached outer surface means that the two unbleached surfaces are in contact with one another when the consumer product is in closed position. This configuration has been found to facilitate sliding upon opening between the two, particularly under humid conditions.

[0042] Preferably, the packaging is folded into shape and maintained in shape with the help of adhesives, such as hot melt adhesives, reactive hot melt adhesives, thermosetting adhesives, pressure sensitive adhesives, contact glue adhesives, preferably, a hot melt pressure sensitive adhesive.

[0066] Preferably the laundry detergent composition comprises a perfume capsule.

[0067] Benefit agents such as perfumes are expensive and generally less cost effective when employed at high levels in fabric care compositions. As a result, there is a desire to maximize the effectiveness of such benefit agents. One method of achieving such objective is to improve the delivery efficiency and active lifetime of the benefit agent. This can be achieved by providing the benefit agent as a component of a capsule. Such capsules are made either by supporting the benefit agent on a water-insoluble porous carrier or by encapsulating the benefit agent in a water-insoluble shell. In the latter category encapsulates are made by precipitation and deposition of polymers at the interface, such as in coacervates, for example as disclosed in GB-A-O 751 600., US-A- 3 341 466 and EP-A-O 385 534, or other polymerisation routes such as interfacial condensation US-A-3 577 515, US-A-2003/0125222, US-A-6 020 066, WO2003/101606, US-A-5 066 419. A particularly useful means of encapsulation is using the melamine/urea - formaldehyde condensation reaction as described in US-A-3 516 941, US-A-5 066 419 and US-A-5 154 842. Such capsules are made by first emulsifying a benefit agent in small droplets in a pre-condensate medium obtained by the reaction of melamine/urea and formaldehyde and then allowing the polymerisation reaction to proceed along with precipitation at the oil-water interface. The encapsulates ranging in size from a few micrometer to a millimeter are then obtained in a suspension form in an aqueous medium. Such capsules provide several benefits. They have the benefit of protecting the benefit agent from physical or chemical reactions with incompatible ingredients in the composition, volatilization or evaporation. Such capsules have the further advantage in that they can deliver the benefit agent to the substrate and can be designed to rupture under desired conditions, such as when a fabric becomes dry. Such capsules can be particularly effective in the delivery and preservation of perfumes. Perfumes can be delivered to and retained within the fabric by a capsule that only ruptures, and therefore releases the perfume, when the fabric is dry. The capsule of the present invention comprises an aldehyde-containing resin. More preferably the capsule has a core-in-shell structure. More preferably the shell is an aminoplast. Most preferably the capsule comprises a formaldehyde-containing shell.

[0068] The capsule preferably comprises a core material and a shell wall material that at least partially, preferably completely surrounds the core material. Said capsule preferably has an average particle size of from about 1 micron to about 100 microns, from about 5 microns to about 80 microns, or even from about 15 microns to about 50 microns.

[0069] Suitable capsule wall materials include materials selected from the group consisting of reaction products of one or more amines with one or more formaldehydes, such as urea cross- linked with formaldehyde or gluterformaldehyde, melamine cross-linked with formaldehyde; gelatin-polyphosphate coacervates cross-linked with gluterformaldehyde; and mixtures thereof. In one aspect, the wall material comprises melamine cross-linked with formaldehyde.

[0070] Useful core benefit agents include perfume raw materials.
