FIELD OF THE INVENTION
[0001] Consumer product comprising a container and a detergent composition.
BACKGROUND OF THE INVENTION
[0002] Detergent compositions, and in particular water-soluble unit dose articles, are liked
by consumers due to their convenience and ease of use. Without wishing to be bound
by theory, 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 are stored and transported in rigid or flexible
plastic containers. Without wishing to be bound by theory, 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.
[0004] An issue is during transport and storage the container comprising water-soluble unit
dose articles can be subjected to extreme variations in temperature. Such environmental
changes can as such result in structural failure of the water-soluble unit dose article.
Structural failure can result in the unit dose article prematurely rupturing and leaking
the internal contents. Such leaked content can hence further contaminate other water-soluble
unit dose article co-stored in the container. A further issue is that such environmental
changes can also result in multiple water-soluble unit dose articles sticking together,
causing inconvenience to the consumer having to re-separate them prior to dosing,
and in a worse case even causing structural failure of the water-soluble unit dose
article upon efforts to separate them.
[0005] A further issue is the containers may accidentally prematurely open during transport.
This premature opening can not only lead to water-soluble unit dose articles moving
out of the storage container but can also result in additional exposure of the water-soluble
unit dose articles to variations in environmental conditions including strong temperature
variations, in addition to contamination of the other enclosed water-soluble unit
dose articles. Therefore, such containers comprise latches to ensure they remain closed
until intentionally opened.
[0006] Therefore, there is a need for a consumer product comprising a water-soluble unit
dose article wherein the incidents of structural failure as a consequence of extreme
temperature variations of said water-soluble unit dose articles is reduced during
transport and storage, wherein the consequence of an incidental structural failure
of a single water-soluble unit dose article on other enclosed water-soluble unit dose
articles is minimized, and also ensuring accidental premature opening is minimised.
[0007] Such issues and needs also apply to detergent compositions provided in other forms
such as, for example, detergent tablets or detergent powder which are also subject
to degradation due to extreme temperature variations and to exposure to moisture.
One should note that in some cases, the containers according to this disclosure may
also be suitable for content other than a detergent product, in particular for content
of a perishable nature, such as food or unstable chemical substances for example.
[0008] It was surprisingly found that a consumer product according to the present invention
overcomes the above problem.

DETAILED DESCRIPTION OF THE INVENTION
Consumer Product
[0010] The present invention is to a consumer product comprising a detergent composition
and a container. The detergent composition and the container are described in more
detail below.
[0011] The consumer product can be sold 'as is', in other words the consumer product is
the item that the consumer picks up from the shelf. Alternatively, the consumer product
could be housed as one unit of a multi-component product. For example, more than one
consumer product could be housed within an outer package and the multiple packaged
consumer products sold together in a single purchase.
[0012] The consumer product may comprise aesthetic elements, for example shrink sleeves
or labels attached to the container. Alternatively, the container may be coloured
or printed with aesthetic elements or informative print such as usage instructions.
Water-soluble unit dose article
[0013] The detergent composition comprises in some examples at least one water-soluble film
orientated to create at least one unit dose internal compartment, wherein the at least
one unit dose internal compartment comprises a detergent composition. The water-soluble
film and the detergent composition, which may be provided in forms other than water-soluble
unit dose articles, are described in more detail below.
[0014] The consumer product comprises a detergent composition, preferably at least one water-soluble
unit dose article.
[0015] A water-soluble unit dose article is generally in the form of a pouch. It comprises
a unitary dose of a composition as a volume sufficient to provide a benefit in an
end application.
[0016] The water-soluble unit dose article comprises at least one water-soluble film shaped
such that the unit-dose article comprises at least one internal compartment surrounded
by the water-soluble film. The at least one compartment comprises a cleaning composition.
The water-soluble film is sealed such that the cleaning composition does not leak
out of the compartment during storage. However, upon addition of the water-soluble
unit dose article to water, the water-soluble film dissolves and releases the contents
of the internal compartment into the wash liquor.
[0017] The unit dose article may comprise more than one compartment, even at least two compartments,
or even at least three compartments, or even at least four compartments, or even at
least five compartments. The compartments may be arranged in superposed orientation,
i.e. one positioned on top of the other. Alternatively, the compartments may be positioned
in a side-by-side orientation, i.e. one orientated next to the other. The compartments
may even be orientated in a 'tyre and rim' arrangement, i.e. a first compartment is
positioned next to a second compartment, but the first compartment at least partially
surrounds the second compartment, but does not completely enclose the second compartment.
Alternatively, one compartment may be completely enclosed within another compartment.
[0018] In some examples, the unit dose article comprises at least two compartments, one
of the compartments being smaller than the other compartment. In some examples the
unit dose article comprises at least three compartments, two of the compartments being
smaller than the third compartment, and preferably the smaller compartments being
superposed on the larger compartment. The superposed compartments preferably are orientated
side-by-side.
[0019] Each individual unit dose article may have a weight of between 10g and 40g, or even
between 15g and 35g.
[0020] Example film is soluble or dispersible in water. Prior to be being formed into a
unit dose article, the water-soluble film preferably has a thickness of from 20 to
150 micron, preferably 35 to 125 micron, even more preferably 50 to 110 micron, most
preferably about 76 micron.
[0021] Preferred film materials are preferably polymeric materials. The film material can,
for example, be obtained by casting, blow-moulding, extrusion or blown extrusion of
the polymeric material, as known in the art.
[0022] Preferably, the water-soluble film comprises polyvinyl alcohol polymer or copolymer,
preferably a blend of polyvinylalcohol polymers and/or polyvinylalcohol copolymers,
preferably selected from sulphonated and carboxylated anionic polyvinylalcohol copolymers
especially carboxylated anionic polyvinylalcohol copolymers, most preferably a blend
of a polyvinylalcohol homopolymer and a carboxylated anionic polyvinylalcohol copolymer.
[0023] Preferably, the water-soluble film comprises a polymer wherein the polymer comprises
a homopolymer, copolymer, or mixture thereof selected from polyvinyl alcohols, polyvinyl
pyrrolidone, polyalkylene oxides, acrylamide, acrylic acid, cellulose, cellulose ethers,
cellulose esters, cellulose amides, polyvinyl acetates, polycarboxylic acids and salts,
polyaminoacids or peptides, polyamides, polyacrylamide, copolymers of maleic/acrylic
acids, polysaccharides including starch and gelatine, xanthum, carragum or a mixture
thereof, preferably, polyvinylalcohol homopolymers and/or anionic polyvinylalcohol
copolymers preferably selected from sulphonated and carboxylated anionic polyvinylalcohol
copolymers especially carboxylated anionic polyvinylalcohol copolymers.
[0024] Preferred films are those supplied by Monosol under the trade references M8630, M8900,
M8779, M8310.
[0025] The film may be opaque, transparent or translucent. The film may comprise a printed
area.
[0026] The area of print may be achieved using standard techniques, such as flexographic
printing or inkjet printing.
[0027] 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.
[0028] The water-soluble film or water-soluble unit dose article or both may be coated with
a lubricating agent. Preferably, the lubricating agent is selected from talc, zinc
oxide, silicas, siloxanes, zeolites, silicic acid, alumina, sodium sulphate, potassium
sulphate, calcium carbonate, magnesium carbonate, sodium citrate, sodium tripolyphosphate,
potassium citrate, potassium tripolyphosphate, calcium stearate, zinc stearate, magnesium
stearate, starch, modified starches, clay, kaolin, gypsum, cyclodextrins or mixtures
thereof.
Container
[0029] The consumer product comprises a container. The container comprises a first part,
wherein the first part comprises a first compartment in which the detergent composition
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.
[0030] 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 for example at least one
water-soluble unit dose article. Preferably, the first opening should be big enough
for a user to fit their hand holding a dosing cup to retrieve for example at least
one dose of a detergent composition in powder form.
[0031] The container comprises a second part, wherein the second part 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. Without
wishing to be bound by theory, the first part and the second part are able to move
relative to one another. This relative movement allows the second part to block entry
to the first opening when not in use, but then allows access to the first opening
when in use. Without wishing to be bound by theory, the user controls the movement
of the first and second parts relative to one another to achieve this.
[0032] The movement of the first part and the second part relative to one another can be
achieved via any suitable means. Those skilled in the art will be aware of suitable
means. The first part may slide within the second part. Alternatively, the second
part may act as a lid to the first part. The lid may be hinged to the first part or
may be completely separated from the first part. Preferably, the second part comprises
a top wall and at least one side wall, and the first part comprises a base, or base
wall, and the first opening, wherein the first opening is located on a sidewall relative
to the base wall. In the closed position the at least one side wall of the second
part overlaps at least partially within the one side wall of the first part. In other
words, the second part acts as a hood positioning over the first part and so blocking
access to the first opening. Alternatively, in the closed position the at least one
side wall of the first part overlaps at least partially within the one side wall of
the second part, in other words, the second part slots inside the first opening blocking
access to the first opening.
[0033] The container further comprises a locking means. The locking means comprises a first
locking component on the first part and a second locking component on the second part.
The first locking component engages the second locking component to prevent sufficient
movement of the second part relative to the first part 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 first part and
the second part comprises an abutment against which the first locking tab is able
to releasably engage.
[0034] 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.
[0035] Preferably both locking means comprise a first locking component on the first part
and a second locking component on the second part. Preferably the first locking means
and second locking means both comprise tabs on the first part and abutments on the
second part.
[0036] The first part 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 first part is constructed from paper-based material so that the detergent composition,
and in particular a water-soluble film of a unit dose article, directly contacts the
paper-based material of the internal surface. In other words, a detergent composition
housed within the container will be in contact with the paper-based material. During
storage and transport, the detergent composition, and in particular the water-soluble
unit dose article, may move within the container, however, there is no impendent between
detergent composition and the paper-based material.
[0037] 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 paper-based material may comprise a printed image thereon.
[0038] Preferably, the entire interior surface of the first part is constructed from a paper-based
material, more preferably, the whole of the first part is constructed from a paper-based
material.
[0039] Preferably, the second part comprises an interior surface and an exterior surface.
Preferably, at least part of the interior surface of the second part is constructed
from a paper-based material, preferably the entire interior surface of the second
part is constructed from a paper-based material, even more preferably, the entire
second part is constructed from a paper-based material.
[0040] Preferably, the first locking component is constructed from a paper-based material
or the second locking component is constructed from a paper-based material or a combination
thereof.
[0041] 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 first part and preferably the internal
surface of the second part 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 first part, external surface of
the second part or a mixture thereof comprises the second material. Alternatively,
the second material might also be laminated in-between two paper-based material layers.
[0042] The first locking component may be a tab made from corrugated fibre-board. Without
wishing to be bound by theory, corrugated fibre-board comprises a series of flutes.
Each flute can be understood to be a channel. The flutes run parallel to one another,
with the flute direction being the direction travelled along each channel. Preferably,
the tab comprises a fold which runs perpendicular to the flute 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.
[0043] Alternatively, the first locking component may be a tab made from paper-board. 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.
[0044] Those skilled in the art will be aware of suitable second materials. Preferably,
the second material comprises a plastic material. Preferably, the plastic material
comprises polyethylene, polyethylene terephthalate, polypropylene, polyvinylalcohol
or a mixture thereof. The barrier material may be a biaxially orientated polypropylene,
a metallised polyethylene terephthalate or a mixture thereof. Alternatively, the second
material may be a wax, a cellulose material, polyvinylalcohol, or a mixture thereof.
[0045] 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 has a thickness of between 10 micron and
40 micron, more preferably between 10 micron and 35 micron.
[0046] Preferably, the second part is a sleeve that receives the first part therein and
the first part is able to slide within the second part between an open position in
which the first opening is accessible and wherein the first locking component and
second locking component are disengaged from one another in a closed position in which
the second part blocks access to the first opening when the first locking component
and the second locking component are engaged.
[0047] Alternatively, preferably, the first part comprises a base wall and the first opening,
wherein the first opening is on a sidewall in relation to the base, the base being
formed of a base wall, and the second part comprises a second opening and at least
one connecting wall, wherein the first part slides within the second part via the
second opening and the connecting wall blocks the first opening when in the closed
position. In this preferred option, the at least one side wall of the first part comprises
the first locking component and the at least one connecting wall of the second part
comprises the second locking component. Preferably, the second part comprises an end
wall opposite to the second opening and the second opening and the end wall are connected
via the at least one connecting wall.
[0048] The connecting wall has an inside surface and an exterior surface. The inside surface
faces the first part and the exterior surface faces the exterior environment to the
container.
[0049] The second locking component may be an abutment formed by cutting a portion of the
connecting wall and folding said portion back upon itself and then adhering said folded
back portion to the inside surface of the connecting wall to create the abutment.
The cut portion of the connecting wall forms the opening of the second locking component.
Alternatively, wherein the second locking component is an abutment, it may be formed
by adhering a separate piece of material, preferably wherein the separate piece of
material is selected from paper, cardboard, or a mixture thereof, to the inside surface
of the connecting wall.
[0050] The container may comprise stopper means to prevent the first part from being completely
removed from the second part. Such stopper means may comprise a stopper abutment on
the second part which interacts with the first locking component, preferably wherein
the first locking component is a tab, preventing further movement of the first part
when being slid out of the second part during use. Without wishing to be bound by
theory, when the first locking component is disengaged from the second locking component,
the first part and second part can be moved relative to one another. During movement,
the first locking component then abuts against the stopper abutment preventing any
further movement. Alternatively, the stopper means may comprise a stopper tab, separate
to the first locking component, that abuts against the second locking means. In this
instance, without wishing to be bound by theory, after disengagement of the first
locking component and the second locking component, the first part and second part
can be moved relative to one another, and the stopper tab abuts against the second
locking means preventing any further movement.
[0051] The stopper means may be formed by folding back the end of the connecting wall and
adhering the folded back part to the inside surface of the connecting wall. The end
of the connecting wall should be understood to mean the edge of the connecting wall
forming the second opening. Alternatively, the stopper means may be formed by adhering
a separate piece of material, preferably wherein the separate piece of material is
selected from paper, cardboard, or a mixture thereof, to the inside surface of the
connecting wall.
[0052] Alternatively, the second part is a removable lid, wherein the second part in a closed
position blocks access to the first opening and when in a closed position the first
locking component is engaged with the second locking component, and when in an open
position the first locking component and second locking component are disengaged and
the second part is removable to allow access to the first opening. Preferably, the
second part is attached to the first part via a hinge or the second part can be completely
removed from the first part. Preferably, the second part can be completely removed
from the first part.
[0053] Preferably, the second part comprises a top wall and at least one side wall, and
the first part comprises a base wall and the first opening, wherein the first opening
is on a sidewall in relation to the base, or base wall. In the closed position the
at least one side wall of the second part overlaps at least partially within the one
side wall of the first part. In this preferred example, the first locking component
is positioned on the at least one side wall of the first part and second locking component
is positioned on the at least one side wall of the second part.
[0054] The at least one side wall of the second part has an inside surface and an exterior
surface. The inside surface faces the first part and the exterior surface faces the
exterior environment to the container. Alternatively, in a less preferred option,
in the closed position the at least one side wall of the first part overlaps at least
partially within the one side wall of the second part.
[0055] The second locking component may be an abutment formed by cutting a portion of the
at least one side wall of the second part and folding said portion back upon itself
and then adhering said folded back portion to the inside surface of the at least one
side wall of the second part to create the abutment. The cut portion of the at least
one side wall of the second part forms the opening of the second locking component.
Alternatively, wherein the second locking component is an abutment, it may be formed
by adhering a separate piece of material, preferably wherein the separate piece of
material is selected from paper, cardboard, or a mixture thereof, to the inside surface
of the at least one side wall of the second part. Alternatively, wherein the second
locking component is an abutment, the second locking component may be formed by folding
the end of the at least one wall of the second part back upon itself and then adhering
the folded portion to the inside surface of the at least one wall of the second part.
[0056] The first part is a box comprising at least a base and sidewalls, whereby the first
opening is located in a specific sidewall. Such a configuration comprising a side
opening can permit in some situation facilitate access to the content of the box,
for example if limited headroom is available due to storage space limitations. Such
a configuration may also avoid or reduce having a lid in the way of the opening. A
base, or base wall, should be understood as a wall on which the container lies when
stored or during use. Graphics or text printed on a container may indicate the position
of the container corresponding to a use or storage position whereby the container
lies on its base, whereby such graphics or text may be read or deciphered by a user
in a straight up position when the container is lying on its base, the base defining
a plane substantially normal to the direction of gravity.
[0057] Providing the first opening on a sidewall according to this disclosure was found
to be particularly helpful for protection of the content. It was indeed found that
containers as described hereby tend to be stored in humid environment such as bathrooms
or laundry rooms for example, such container being exposed to lying on a wet floor,
thereby exposing their base or base walls to humidity, or to splashing, the splashing
primarily impacting a top region of the container opposite to the base. Providing
the first opening in a sidewall thereby avoid providing an opening in such a top region,
thereby providing for additional protection from humidity, whereby the top region
may result more sturdy. In some examples, the top region of the container is entirely
covered by a top wall of the first part and entirely covered by a top wall of the
second part when the container is not in use, thereby providing at least a double
layer structure protecting the top region when the container is not in use. In addition
to this, placing the first opening on a sidewall may results in the first opening
being in a substantially vertical plane, i.e. a plane substantially parallel to the
direction of gravity. This can result in potential water splashes running down along
the sidewall instead of entering directly into the first opening or instead of structurally
weakening a panel of the cover covering the opening, in particular a paper based or
cardboard based panel of such cover.
[0058] In some examples, the box comprises at least 6 sides, whereby at least 2 specific
sides of the at least 6 sides are larger in surface than any other sides, whereby
the specific sidewall, in which the first opening is located, corresponds to one of
the specific sides. This permits providing a relatively larger opening, thereby easing
access to the content of the container. In some examples, the at least 2 specific
sides of the at least 6 sides are at least 10% larger in surface than any other sides.
In some examples, the at least 2 specific sides of the at least 6 sides are at least
20% larger in surface than any other sides. In some examples, the at least 2 specific
sides of the at least 6 sides are at least 30% larger in surface than any other sides.
In some examples, the at least 2 specific sides of the at least 6 sides are at least
40% larger in surface than any other sides. In some examples, the at least 2 specific
sides of the at least 6 sides are at least 50% larger in surface than any other sides.
In some examples, the at least 2 specific sides of the at least 6 sides are at least
60% larger in surface than any other sides. Providing a container having an elongated
shape factor whereby the at least 2 specific sides are particularly large compared
to the any other sides permits having a particularly large opening without requiring
providing a box having a relatively large volume. This permits using the box in a
constrained storage environment without compromising ease of access to the content
of the box.
[0059] In some example, the first opening is located in a region of the specific sidewall
away from the base, whereby the first opening is preferably a permanent opening. A
configuration whereby the first opening is located in a region of the specific sidewall
away from the base permits avoiding having content escaping the box through such opening
in an undesired manner when the box lies on its base. In some examples, a lowest point
of the opening is at least 30%, preferably at least 50%, more preferably at least
70% away from the base, the % being relative to the distance between the base and
the top of the specific sidewall when the container lies on its base. Using a permanent
opening facilitates access by avoiding additional operations to access the content
of the box beyond the operation of the lock according to this disclosure.
[0060] In some examples, the first opening is located in a region of the specific sidewall
adjacent to the base, whereby the first opening is preferably a reclosable opening.
Providing a first opening adjacent to the base may facilitate dispensing the content,
and may facilitate ensuring that all or most of the content may be accessed, even
if located at the bottom of the box. In some examples, a lowest point of the opening
is at most 30%, preferably at most 20%, more preferably at most 10% away from the
base, the % being relative to the distance between the base and the top of the specific
sidewall when the container lies on its base. In such configurations, using a reclosable
opening permits an additional control of content access or content dispensing in addition
to the lock or locking means according to this disclosure, for example in order to
compensate the fact that the content would be more likely to escape through the first
opening in an undesired manner in such cases.
[0061] In some examples, the first opening spans an area of at least 25cm
2. This sizing permits providing appropriate access to the content of the box. In some
examples, the first opening spans an area of less than 90%, preferably less than 80%,
more preferably less than 70%, even more preferably less than 60% and most preferably
less than 50% of the specific sidewall, thereby permitting maintaining a sufficient
structural integrity of such sidewall.
[0062] In some examples, the first opening is one of a complete cut out opening or preferably
a partial cut out opening. In some cases, providing such a cut out permits ensuring
that the container has not been tempered with. In some cases, the cut out is provided
by way of a line of weakness. In some examples, the cut out is provided by pre-perforations.
In some examples, the partial cut out is a hinged flap, the hinge being preferably
located adjacent to the base, the hinge being preferably parallel to the base. In
the case of a partial cut out opening, such partial cut out opening may provide for
at least partially reclosing the first opening, as an additional protection for the

polyethyleneimines, soil release polymer, surfactant, solvent, dye transfer inhibitors,
chelant, encapsulated perfume, polycarboxylates, structurant, pH trimming agents,
and mixtures thereof.
[0083] An issue is during transport and storage perfume will partially migrate from the
detergent composition, for example through the water-soluble film in the case of water-soluble
unit dose articles, and start building up in the headspace of the container. Some
consumers, however, do not like strong perfumes applied to their clothes, e.g. they
desire minimum perfume application, purely as a sign that their clothes are clean
and refreshed but do not want to experience an "overwhelming" perfume. To them, a
strong perfume headspace build up in the tub is undesired as it is perceived as a
signal that during washing also a strong perfume will be applied to their clothes.
Even when formulating a "light" perfume targeting this consumer segment the perfume
build-up in the headspace experience is still to be improved.
[0084] A possible solution could be for the consumer to store the containers in an open
position such that a perfume headspace cannot build up. This is undesired however,
as it will increase the sensitivity of the detergent composition to external humidity
conditions as well as the risk of accidently contaminating the detergent composition.
More importantly, while keeping the container open would reduce the risk of strong
perfume build up in the storing container, this approach will not provide the consumer
a reassuring signal that the detergent composition is not comprising a strong perfume.
He/she will not know as there would not be a perfumed headspace based on which the
consumer can judge whether the formulated perfume would match his/her need. Therefore,
the consumer prefers such containers comprise latches to ensure they remain closed
until intentionally opened, such that a perfume headspace can build-up and the consumer
is able to judge the strength of the perfume based on the perfume build-up in the
headspace.
[0085] Therefore, there is a need for a consumer product comprising a detergent composition
comprising a perfumed detergent composition in which strong perfume build-up in the
headspace while stored in a closed position is avoided.
[0086] It was surprisingly found that a consumer product according to the present invention
overcomes the above problem.
[0087] Preferably, the laundry detergent composition has a pH between 6 and 10, more preferably
between 6.5 and 8.9, most preferably between 7 and 8, wherein the pH of the laundry
detergent composition is measured as a 10% product concentration in demineralized
water at 20°C.
[0088] When liquid, the laundry detergent composition may be Newtonian or non-Newtonian.
Preferably, the liquid laundry detergent composition is non-Newtonian. Without wishing
to be bound by theory, a non-Newtonian liquid has properties that differ from those
of a Newtonian liquid, more specifically, the viscosity of non-Newtonian liquids is
dependent on shear rate, while a Newtonian liquid has a constant viscosity independent
of the applied shear rate. The decreased viscosity upon shear application for non-Newtonian
liquids is thought to further facilitate liquid detergent dissolution. The liquid
laundry detergent composition described herein can have any suitable viscosity depending
on factors such as formulated ingredients and purpose of the composition.
[0089] Those skilled in the art will know how to formulate and make a suitable detergent
composition using known knowledge and techniques.
Manufacture
[0090] Those skilled in the art will be aware of standard techniques and methods to make
the consumer product according to the present invention. Those skilled in the art
will be aware of methods to make the detergent composition, preferably at one or more
water-soluble unit dose articles. Those skilled in the art will be aware of standard
methods to make the container. Preferably, the first part is constructed from a first
blank and the second part is constructed from a second blank.

limited to the exact numerical values recited. Instead, unless otherwise specified,
each such dimension is intended to mean both the recited value and a functionally
equivalent range surrounding that value. For example, a dimension disclosed as "40

adhering the folded portions to the inside surface of the respective connecting wall
(21, 22, 23, 24).
FIG. 10A and FIG. 10B depict a cross-sectional view of the consumer product (1) according
to FIG. 4. In FIG. 10A the first locking component (7) is engaged with the abutment
(10). The abutment (10) is formed by cutting a portion of the connecting wall (18)
and folding said portion back upon itself and then adhering said folded back portion
to the inside surface of the connecting wall (18) to create the abutment. The resulting
hole creates the opening (11). In FIG. 10A the user disengages the first locking component
(7) from the abutment (10) via application of force (14) through the opening (11).
As shown in FIG. 10B, the application of force (14) displaces the first locking component
(7), allowing the user to move the second part (4) away (15) from the first part (3)
until the first locking component (7) abuts against the stopper abutment (19) preventing
further movement. FIG. 10B depicts a cross-sectional view of the consumer product
(1) in the open position.

in the same way as depicted in FIG. 10. Shown are two opening (11) corresponding to
two separate second locking components (8).
FIG. 12 discloses a water-soluble unit dose article according to some examples of
the present invention. The water-soluble unit dose article (3) comprises a first water-soluble
film (301) and a second water-soluble film (302) which are sealed together at a seal
region (303). A detergent composition, preferably a laundry detergent composition
(304) is comprised within the water-soluble soluble unit dose article (3).
Example 1 : Impact of container material
[0093] Leakers are an ongoing complaint for Laundry soluble unit dose article consumers.
Temperature shocks, especially strong temperature drops during storage exposure, have
been identified as a core driver of unit dose article leakage in a storage container.
In this study we cross-compared the impact of the container material in view of leakage
prevention upon thermal shock exposure, more particularly paper-based containers were
single variably compared versus traditional in market plastic type containers. Therefore
closed packages of similar dimensions comprising 38 water soluble unit dose articles
were exposed to 5 thermal shock cycles (one cycle : 7 hrs in 50°C climate room, followed
by 15 minutes in 20°C climate room). A commercial plastic bag has also been added
into the comparison. No additional mechanical action (vibration) was added during
the testing. After every cycle packages were visually checked for leakers. 5 replicates
of each container type were tested and the average number of leakers is reported.
Materials :
[0094]
- Water soluble unit dose article : Ariel 3 in 1 Pods, as commercially available in
the UK in April 2019
- Plastic tub & lid: Ariel 3 in 1 Pods Polypropylene tubs & lids, as commercially available
in the UK in April 2019 (dimensions : Length=250mm; Height=135mm; width=106mm, count
size : 38)
- Plastic bags : Fairy Platinum multi-laminate (Polyethelene/Polyethylene Terephtalate)
bag, as commercially available in the UK in April 2019 (dimensions : length=278mm;
height=214 mm; width = 87mm, count size : 38)
- Paper-board container (dimensions : Length=245mm; Height=135mm; width=96mm, material
100% virgin fiber GN4 480gsm commercially available from BillerudKorsnas Carry ref.
BKC480, count size : 38)
- Corrugated fibre-board container (dimensions Length=245mm; Height=135mm; width=96mm,
material: E-flute corrugated board 382 gsm KW2 135 / RF 1 90/ Board KW2 135, count
size : 38)
Results:
[0095] The leakage results in table 1 clearly show that unlike plastic tubs or bags, paper
based containers according to the invention show absence of leakers under influence
of a thermal shock exposure.

Example 2 : Impact of lamination
[0096] The impact of lamination on leaker formation upon thermal shock exposure was tested
by adding a paper layer (A4 - 80gsm paper glued on the surface) respectively over
the entire inside and over the entire outside of a 38 ct plastic polypropylene tub
(as in example 1). Both legs are as such designed to have the same thermal inertia
upon a thermal shock with the intent of evaluating single variable the role of a lamination
layer. Both tubs were again filled with 38 pouches and exposed through 5 thermal shock
cycles as described above.
Results:
[0097] The leakage results in table 2 clearly show that while lamination of a paper based
material with a secondary plastic material does not obsolete the learning ex example
1 above, it is critical when laminating to have the paper based material on the inside
of the storage container.
