FIELD OF THE INVENTION
[0001] The present invention relates to a packaging for water-soluble unit dose articles
and packages comprising water-soluble unit dose articles.
BACKGROUND OF THE INVENTION
[0002] Water-soluble unit dose articles are liked by consumers as they are convenient and
efficient to use in wash operations. Such articles comprise a water-soluble film which
defines at least one internal compartment wherein the compartment houses a detergent
composition.
[0003] Water-soluble unit dose articles are often sold to consumers in containers with lids.
Closure of the lids aims to minimise moisture ingress into the containers which can
affect the physical stability of the internal water-soluble unit dose articles. Such
ingress is particularly problematic in high humidity environments such as those found
in the vicinity of the wash operation (such as laundry or dish washing). Closure of
lids also aims to reduce spillage or removal of the articles from the container when
it is not intended or otherwise desirable, for example, if the container were to fall
or become upside down or fall on its side. Therefore, such containers are manufactured
with locking means to ensure the lid remains closed when not in use.
[0004] In addition, when the lid of the container is closed, the locking means serve to
hinder the ability of children (of less than 5 years), to gain access to the contents
of the container and subsequently become exposed to the water-soluble unit dose articles.
[0005] Traditionally such containers were manufactured such that the locking means was located
on the front outer surface of the container. These types of locking means comprised
a part on the lid and a part on the container wall and were disengaged by the user
pushing or pulling the lid component towards or away from them releasing it from the
wall component. However, one potential issue with the location of such locking means
was that there may be a tendency for them to be damaged during transport, particularly
if the packages are not packed for transport in such a way as to specifically reduce
damage. This damage was caused by adjacent containers hitting into one another or
rubbing against one another causing the locking means on the outer surface of the
tub to be damaged.
[0006] In an attempt to overcome these issues, manufacturers have relocated the wall component
of the lock to the top of the container wall, with a corresponding lid component remaining
in the lid. This relocation of the locking means remained intuitive for adults in
terms of how to operate it, yet reduced the number of instances of damage during manufacture,
shipping and storage. In addition, relocating the locking means in such a way made
it even more difficult for children to locate the locking means on the container.
[0007] However, it was found that such locking means can be difficult for consumers to disengage
as they required the wall component to be pushed away from the user whilst simultaneously
lifting the lid. This might result in the container simply being pushed away from
the consumer rather than the lock disengaging and/or the consumer found the whole
operation awkward or uncomfortable to the fingers and hand.
[0008] US20150315532 discloses a container with a lid that can be opened in a user-friendly manner. The
container has two closing means wherein the first closing means can be opened by direct
application of force to the respective frame section and the second closing means
can be opened by application of direct force to the respective lid section.
[0009] Therefore, there remains a need in the art for a container comprising water-soluble
unit dose articles wherein the container comprises a locking means that effectively
keeps the lid closed when not in use and does not suffer from damage associated with
the locking means being attached to the front of the container whilst remaining comfortable
and intuitive for the consumer to operate. In addition, the container should hinder
the ability of children to gain access to the contents of the container when the lid
is closed.
[0010] It was surprisingly found that the container according to the present invention overcame
these problems. Without wishing to be bound by theory, the locking means of the present
container requires the user to operate a 'pinching motion' to disengage the locking
means. Such a motion is more comfortable and intuitive for the human hand and also
allows for the consumer to simultaneously lift the lid. The locking means also effectively
keeps the lid closed when not in use.
[0011] Furthermore, manufacturing efficiency of containers comprising water-soluble unit
dose articles can be improved as the number of instances of the closing means being
damaged during manufacture is reduced.

DETAILED DESCRIPTION OF THE INVENTION
Consumer Product
[0014] The present invention is to a consumer product comprising a container and at least
one water-soluble unit dose article.
[0015] The at least one water-soluble unit dose article is contained within the container.
The container and the water-soluble unit dose article are described in more detail
below.
[0016] 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.
[0017] 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.
Container
[0018] The consumer product comprises a container. The container needs to be capable of
containing the at least one water-soluble unit dose article. The container may have
any suitable size dependent upon the number of water-soluble unit dose articles contained
within the container.
[0019] The container may be of any suitable shape. The container may have an overall straight
shape, e.g. with straight sides, or may have a curved shape or may comprise both straight
and curved elements. The container may comprise flat surfaces as well as surfaces
comprising embossments or other structural element, e.g. designed to improve gripping
or structural integrity.
[0020] Preferably the container has a rectangular shape when viewed from the top of the
bottom. When viewed from the bottom, the rectangular shape has a length to width ratio
between 1.5:1 and 2.5:1.
[0021] The container may have a measured length of between 100mm and 300mm, preferably between
140mm and 260mm. The container may have a measured width between 60mm and 140mm, preferably
between 65mm and 115mm.
[0022] The container may have any suitable shape. Those skilled in the art will be aware
of suitable shapes. The container may have a cubic shape, a cylindrical shape, a rectangular
shape or a mixture thereof. Whilst the container may have an overall linear shape,
for example rectangular, it may comprise curved walls. For example, when viewed from
above the container may have rectangular shape, however, when viewed from the front
it may comprise convex curved walls curving from the top of the container to the bottom
of the container.
[0023] The container may be made from any suitable material. The container may be made of
natural materials, synthetic materials or a mixture thereof, preferably synthetic
materials, more preferably plastic.
[0024] The container may be made from plastic materials, metallic materials, paper materials,
or a mixture thereof. The container may be made from materials comprising recycled
materials.
[0025] The container may be made from a plastic material, preferably a polyolefin material.
The container may be made from polypropylene, polystyrene, polyethylene, high-density
polyethylene, polyethylene terephthalate, polyvinyl chloride, Acrylonitrile Butadiene
Styrene, Polycarbonates, Polyamides or a mixture thereof. Preferably, the container
may be made from polypropylene, polystyrene, high-density polyethylene, polyethylene
terephthalate, or a mixture thereof
[0026] The plastic material may have a tensile modulus ranging from 1250MPa to 3000MPa,
preferably between 1300MPa and 2300MPa. Those skilled in the art will know how to
measure tensile modulus using techniques commonly known in the art.
[0027] The container may be made from metallic materials wherein the metallic material is
preferably selected from aluminium, steel or a mixture thereof.
[0028] The container may be made from paper materials wherein the paper material is preferably
selected from carboard, laminates, cellulose pulp materials or a mixture thereof.
[0029] The material used to make the container may comprise other ingredients, such as colorants,
preservatives, plasticisers, UV stabilizers, Oxygen, perfume, recycled materials and
moisture barriers or a mixture thereof. The container may comprise areas of external
or internal printing.
[0030] The container may be made using any suitable process.
[0031] Suitable processes include but are not limited to thermoforming, injection molding,
injection stretch blow molding, extrusion blowmolding, or a mixture thereof preferably
thermoforming or injection molding or a mixture thereof.
[0032] Suitable processes include, but or not limited to, tube forming from a flat laminate
with a welding step, extruded tube forming, folding or a mixture thereof.
[0033] The container may be opaque translucent, or a mixture thereof. Preferably, the container
is opaque.
[0034] The container comprises a base. When at rest the base is located on the underside
of the container as it rests on a surface. The base may be substantial flat, that
is to say not comprising areas that are substantially raised versus other areas. Alternatively,
the base may comprise a raised area. This has the benefit of creating a reservoir
within the container which can catch any leaked detergent composition from ruptured
unit dose articles. This has the advantage of minimizing unwanted contact between
unruptured unit dose articles and the leaked composition.
[0035] The container comprises an opening positioned opposite to the base. At least one
wall extends vertically from said base to said opening. By vertically in this context
we herein mean approximately vertical. In other words, the wall does not to extend
from the base at an angle of exactly 90° rather there can be variation either side
of exactly 90°. Those skilled in the art will understand what relevant variation there
can be. The wall may extend from the base at an angle between 75° and 105°, preferably
between 80° and 100°, more preferably between 85° and 95° relative to the base. Preferably
the container comprises at least 2 walls, preferably at least 3 walls, most preferably
at least 4 walls extending between said base and said opening. Preferably the container
comprises 4 walls so that the container has an overall square or rectangular shape.
[0036] The at least one wall terminates in an upper edge of said at least one wall. The
upper edge should be understood to be top of the at least wall. The upper edge is
preferably horizontal such that it is parallel to the base. However, the upper edge
does not have to be completely horizontal, for example it can have elevated areas
or run with a substantially diagonal direction.
[0037] The width of the upper surface may correspond to the thickness of the at least one
wall. However, the upper surface may be thinner or thicker than the at least one wall.
The upper surface may comprise different thickness within the same container. The
thickness of the upper surface of one wall may differ to the thickness of the upper
surface of another wall on the same container.
[0038] The thickness of the upper surface may be between 1mm and 8mm, preferably between
2mm and 6mm.
[0039] Indeed, the at least one wall may comprise at least two sections. The two sections
may differ in height, thickness or both. The width of the upper edge may correspond
to the thickness of one section of the at least one wall.
[0040] The at least two sections are joined together, via mechanical connection, via adhesive
or a combination thereof. Mechanical connections may comprise simple hooks on one
or both of the sections. Preferably, the at least two sections are joined together
via use of both mechanical connections and adhesive. By adhesive we mean hot melt
adhesive, reactive hot melt adhesive, thermosetting adhesive, pressure sensitive adhesive,
contact glue adhesive. Preferably, the adhesive is a hot melt pressure sensitive adhesive.
Preferably, the hot melt pressure sensitive adhesive is suitable to tackify and bond
to a range of materials including one or more materials mentioned above. Preferably,
the at least one wall comprises a lower section and an upper section. The lower section
rises up from the base. The upper section is then joined to the lower section preferably
via adhesive and comprises the upper edge. Alternatively, the at least two sections
may be arranged vertically such that both sections raise up adjacent to one another
from the base.
[0041] The at least one wall may be made from rigid material, a flexible material or a mixture
thereof. The base may be made from a rigid material, a flexible material or a mixture
thereof. The at least one wall may comprise an upper section and a lower section wherein
the upper section is made of rigid material and the lower section is made from flexible
material, and preferably wherein the base is made from flexible material.
[0042] The at least one wall comprises an inner surface and an outer surface. The outer
surface is in contact with the exterior environment to the container, whereas the
inner wall is in contact with the interior environment of the container.
[0043] The base and the at least one wall define an internal compartment. The inner surface
of the at least one wall is in contact with the environment of the internal compartment.
[0044] The internal compartment is accessible from the opening. The container may comprise
more than one internal compartment. The container may comprise at least one compartment,
or at least two compartments or at least three compartments.
[0045] The container also comprises a lid. The lid is able to move from an open to closed
position via a hinge. When in the closed position, the lid covers the opening. By
'cover the opening' we herein mean preferably, at least 90%, more preferably at least
95%, even more preferably at least 98% of the area of the opening is covered by the
lid. It should be understood that due to manufacturing tolerances etc, there may still
be a gap between the upper edge and the lid when closed, but the intention is that
any gap present is not large enough to allow access to the opening by the user or
allow the at least one water-soluble unit dose article to be removed purposively or
accidentally from the internal compartment.
[0046] At least part of the opening may comprise a permanent cover, and the lid covers the
remaining area of the opening.
[0047] If the lid is assumed to be at an angle of 0° when closed, then the lid can open
to a maximum angle relative to that when closed of between greater than 0° and 270°,
preferably between 60° and 180°, more preferably between 90° and 150°.
[0048] The container comprises at least one locking means. Preferably, the container comprises
at least two locking means. Preferably, the at least two locking means are spaced
apart by a distance of from 50mm to 180mm. The at least two locking means might be
present on the same wall or on different walls, preferably on the same wall. Preferably
the container comprises two locking means, as such fitting the number of consumer
hands and enabling the consumer to open the container in a coordinated motion.
[0049] The locking means comprises a lid component and a wall component. In other words,
a component of the locking means is located on or within the lid and a separate component
of the locking means is located on the inner surface of the at least one wall or on
the upper edge. The interaction of the lid component and the wall component results
in the locking means being engaged and the lid being secured in a locked position.
[0050] The lid component is preferably simply a recess or hole in the lid able to accommodate
the hook member. The recess or hole can be of any suitable shape, providing it can
receive the hook member and allows for engagement of the hook member to lock the lid
in place and disengagement of the hook member via an appropriate action to disengage
it.
[0051] The wall component comprises a support member and a hook member. The support member
extends from the upper edge of the at least one wall or the inner surface of the at
least one wall. The hook member is attached to the support member. The support member
and hook member may be two separate pieces joined together. Alternatively, the support
member and hook member can be formed from one integral part.
[0052] Preferably, the support member and the hooking member are arranged such that the
wall component is in the shape of an inverted U. Preferably, the U shape is attached
to the inner wall or the upper edge via a horizontal connecting member, or substantially
horizontal connecting member extending from the inner wall or the upper edge to the
support member. By substantially horizontal we herein mean the connecting member is
not perfectly horizontal but may be at a slight angle. Those skilled in the art will
understand what relevant variation there can be. The connecting member may extend
from the inner wall at an angle between 75° and 105°, preferably between 80° and 100°,
more preferably between 85° and 95° relative to the inner wall. Despite the angle
the connecting member will still achieve the same benefit as a perfectly horizontal
connecting member.
[0053] When the lid is in a closed position, the hook member engages the lid component such
that application of force to the hook member is needed to disengage the wall component
from the lid component. Preferably, a counterforce is needed by the user to disengage
the wall component from the lid component. Such counterforce is preferably as a result
of the finger/thumb pinch motion in which the finger or thumb is placed on the hook
member and the other digit is placed on the outer surface of the wall or side of the
lid. The user then pinches the thumb and finger together disengaging the wall component
from the lid component using the side of the lid or outer surface of the wall as the
surface for effecting the counterforce.
[0054] The hook member extends from the support member towards the interior of the container
such that to disengage the wall component from the lid component requires application
of force to the hook member. The application of force to the hook member is in the
direction towards the inner wall. In other words, application of force pushes the
hook member towards the support member which extends from the inner wall.
[0055] Preferably, the support member extends from the inner surface of the at least one
wall and the wall component is positioned such that it does not extend higher than
the upper edge of the at least one wall. In other words, the wall member does not
protrude above the height of the at least one wall.
[0056] Preferably, upon engagement of the wall component with the lid component, the support
member and hook member are arranged such that the hook member resists rotational movement,
whilst still allowing the wall component as a whole to move in response to the force
exerted by the engagement of the wall component with the lid component. In other words,
during engagement, the wall component may be displaced, but returns to its original
position upon engagement of the lid component with the wall component. During this
displacement, preferably, the hook member itself is not displaced versus the support
member.
[0057] Alternatively, upon engagement of the wall component with the lid component, the
support member and hook member are arranged such that the support member resists any
movement, whilst still allowing the hook member to move in response to the force exerted
by the engagement of the wall component with the lid component. In other words, during
engagement, the hook member may be displaced, but returns to its original position
upon engagement of the lid component with the wall component.
[0058] Preferably, the hook member engages the lid component in two axes. This will be demonstrated
in the examples.
[0059] Preferably, the unlocking of the hook member from the lid component does not deform
the lid or the at least one wall. By deformation we herein mean permanent or temporary
deformation of the shape of the wall or lid is not necessary in order to unlock the
hook member from the lid component. Some minor temporary deformation of the shape
of the wall or lid may be experienced due to the force of the user opening the locking
means, but such minor deformation is not necessary to the operation of the locking
means.
[0060] Preferably, the outer surface of the at least one wall is devoid of any locking means.
By this we mean that preferably no component of a locking means is present on the
outer surface of the at least one wall. In this instance, the locking means can mean
the locking means as described above or any other locking means.
[0061] Preferably, the container has a footprint defined as the largest horizontal cross-sectional
area through the container and the at least one locking means does not extend beyond
the footprint of the container. In other words, the at least one locking means preferably
does not extend any further into the external environment than the outer surface of
the at least one wall.
[0062] Preferably, the lid comprises a recess surrounded by an outer ridge. Preferably,
the lid component is comprised within the outer ridge. The outer ridge may comprise
an inner side, an outer side and a top and wherein the lid component is comprised
within the inner side, the top, or a mixture thereof. Preferably, the lid component
is a hole through the lid.
[0063] Preferably, the lid has a footprint defined as the largest horizontal cross-sectional
area of the lid when in a closed position and the container has a footprint defined
as the horizontal cross-sectional area through the container and wherein the footprint
of the lid is greater than the footprint of the container. In other words, the area
of the lid is preferably greater than that of the area of the opening of the lid and
the upper edge. This means that when the lid is in the closed position it preferably
completely covers the opening of the container and extends over the upper edge of
the at least one wall. Preferably, a lip extends from the outer surface of the at
least one wall such that the footprint of the lip is the same as, or greater than
the footprint of the lid. If the lip extends to a point greater than the footprint
of the lid, then the lip may have an 'L' or 'J' shape. The lip may be interrupted
in the area aligned with the locking means. In other words, the lip may be discontinuous
and comprise a gap corresponding to the location of the locking means being present
on the upper edge or inner wall of the at least one wall. Without wishing to be bound
by theory, this gap may also serve as the counterforce point for the finger/thumb
pinch motion. The lid may comprise an element to act as a counterforce surface for
the finger or thumb of the consumer.
[0064] The lid is able to move from an open to a closed position and vice versa via a hinge.
Preferably, the lid is attached to the container via at least one hinge. More preferably,
the container comprises a first wall and a second wall, wherein the hinge is connected
to the second wall, and wherein the first wall is positioned opposite the second wall,
and wherein the first wall comprises the at least one locking means, preferably at
least two locking means.
[0065] The hinge can be any suitable hinge. Those skilled in the art will be aware of suitable
hinges. The hinge may be a living hinge or an assembled hinge, or a mixture thereof.
A living hinge is understood to be an integrated component made of the same material
as the lid and the container. It is essentially a thin flexible area of material allowing
movement between the lid and container.
[0066] Preferably the hinge is a living hinge. The living hinge may be a bi-stable hinge
or a butterfly hinge or a mixture thereof.
[0067] The container may comprise a biasing system that biases the lid towards the open
position. The biasing system may comprise an elastic member. More preferably, a projection
located on the closure system, preferably on the lid, elastically deforms the elastic
member when the lid is in the closed position.
[0068] The lid may comprise debossed or embossed regions to indicate to the consumer the
location of the locking means when the lid is closed and/or direction in which force
needs to be applied to release the locking means.
Method of assembly
[0069] The consumer product may be assembled using any suitable technique. Those skilled
in the art will be aware of suitable techniques. The consumer product may be assembled
using an automated system, a manual system or a mixture thereof.
[0070] The consumer product may be assembled by forming the container, then adding the water-soluble
unit dose articles and then closing the lid. Filling of the container may be done
via a suitable automated process or manually.
[0071] The consumer product may be assembled by forming the base and lower wall sections.
The water-soluble unit dose articles are then added. Upper wall sections comprising
the lid and manufactured separately are then added to the upper wall sections and
base containing the water-soluble unit dose articles. Filling of the container may
be done via a suitable automated process or manually.
Water-soluble unit dose article
[0072] The consumer product comprises at least one water-soluble unit dose article, preferably
at least two water-soluble unit dose articles.
[0073] 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.
[0074] 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.
[0075] The film is described in more detail below.
[0076] 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.
[0077] Wherein the unit dose article comprises at least two compartments, one of the compartments
may be smaller than the other compartment. Wherein the unit dose article comprises
at least three compartments, two of the compartments may be smaller than the third
compartment, and preferably the smaller compartments are superposed on the larger
compartment. The superposed compartments preferably are orientated side-by-side.
[0078] The cleaning composition may be a laundry detergent composition, an automatic dishwashing
composition, a hard surface cleaning composition or a combination thereof. The cleaning
composition may comprise a solid, a liquid or a mixture thereof. The term liquid includes
a gel, a solution, a dispersion, a paste or a mixture thereof.
[0079] The unit dose article has a height, a width and a length. The maximum of any of these
dimensions is meant to mean the greatest distance between two points on opposite sides
of the unit dose article. In other words, the unit dose article may not have straight
sides and so may have variable lengths, widths and heights depending on where the
measurement is taken. Therefore, the maximum should be measured at any two points
that are the furthest apart from each other.
[0080] The maximum length may be between 2cm and 5 cm, or even between 2cm and 4cm, or even
between 2cm and 3cm. The maximum length maybe greater than 2cm and less than 6cm
[0081] The maximum width may be between 2cm and 5cm. The maximum width maybe greater than
3cm and less than 6cm.
[0082] The maximum height may be between 2cm and 5cm. The maximum height maybe greater than
2cm and less than 4cm.
