STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT
[0002] (NOT APPLICABLE)
FIELD OF THE INVENTION
[0003] This invention relates to containers of the kind having an
outlet through which product is to be dispensed, e.g. food
product.
BACKGROUND OF THE INVENTION
[0004] It is known, from previous applications such as WO96/01224
and WO94/13154, to provide containers from which food product,
particularly ice cream or other frozen confections e.g. sorbet,
frozen yoghurt, can be extruded through an outlet whose
cross-section is less than the cross-section of the container.
Reducing the internal volume of the container can be done in a
range of different ways, such as deforming the container or by
using a piston inside the container. The containers have an outlet
through which product is discharged and the outlet shapes the
product during discharge.
[0005] Conventionally, the containers are provided with a
protective sticker placed over the outlet in order to protect the
product from the outside environment. This protective sticker is
removed prior to the container being placed in the dispensing
machine and the product being dispensed. It is desirable to provide
an alternative to a protective sticker, and preferably provide a
container which is compatible with existing dispensing
machines.
[0006] Previous application WO03/010062 provides a container with
displaceable parts which can move from a closed position to an open
position to define an outlet of the container.
[0007] However, there can be difficulties when moulding or
operating such containers.
[0008] The present invention aims to overcome or mitigate the
problems associated with the prior art.
BRIEF SUMMARY OF THE INVENTION
[0009] According to one aspect, there is provided a container for
product to be dispensed. The container has an upper part intended
to move or deform in order to reduce the volume within the
container. The container has an outlet intended to open during
movement or deformation of said upper part. The outlet comprises a
plurality of movable parts. The outlet further comprises a
plurality of fixed parts located between said movable parts. The
movable and fixed parts are arranged for shaping product as it is
dispensed from the container through the outlet.
[0010] The use of moving and fixed parts to define the outlet
simplifies the moulding of the containers, and has been found to
provide improved operation of the outlet in use, i.e. with less
tendency for one or more of the movable parts to resist movement to
an open position.
[0011] In exemplary embodiments, the outlet may define a
star-shaped opening.
[0012] In exemplary embodiments, the movable parts comprise a free
end, distal the hinge, the free end comprising an end surface, the
movable parts further comprising at least one side surface, wherein
the end surface of a first movable part and the side surface of a
second movable part are adjacent when the outlet is in a closed
condition. In exemplary embodiments, the end surface is shorter
than the length of the hinge. In exemplary embodiments, the end
surface is shorter than the length of said side surface.
[0013] In exemplary embodiments, the movable parts are hingedly
coupled with the container. The hinge may comprise a groove. The
groove may have at least one internal radius. The groove may have
two internal radii. The hinge may be defined by a groove which
defines an open channel, having opposing walls and a transition
wall therebetween. The joint between said walls may define a
radius. The hinge may have a thickened area in relation to the
remainder of the hinge. There may be a thickened area at or
adjacent to one or both ends of the hinge lengthways.
[0014] In exemplary embodiments, the movable parts comprise a free
end, distal the hinge, the free end comprising an end surface, the
movable parts further comprising at least one side surface, wherein
at least a part of the side surface of a first movable part may be
in abutment or proximal the end surface of a second movable part
when the outlet is in a closed condition.
[0015] In exemplary embodiments, the movable parts include a
projection on an internal surface, configured to help create the
desired shape of product during dispensing.
[0016] In exemplary embodiments, the container may further comprise
at least one locking mechanism configured to retain the movable
parts in a closed position with a retaining force until a
predetermined pressure is reached within the container. The locking
mechanism may be a tab configured to retain the movable parts in
the closed position until the product is dispensed. The tab may be
located on the fixed parts, and arranged to engage the movable part
when the outlet is in a closed condition. The movable parts may be
configured to overcome the retaining force of the locking mechanism
and move to an open position when a predetermined pressure is
reached within the container. The locking mechanism may be
configured to deform in order to permit the movable parts to move
to an open position when a predetermined pressure is reached within
the container.
[0017] In alternative embodiments, the outlet of the container
includes a membrane after manufacture of the container, configured
to retain the movable parts in a closed position with a retaining
force until the membrane is broken.
[0018] Advantageously, the membrane allows product to be
hermetically sealed within the container until dispensing is
desired.
[0019] The membrane may be located between the fixed and movable
parts of the outlet and between adjacent movable parts, such that
when the membrane is broken, the movable parts are free to move to
an open position.
[0020] The membrane may be formed of thinner material than the
fixed parts of the outlet, such that, in use, the membrane breaks
and the fixed parts remain unbroken, e.g. by modifying a mould used
to manufacture the container accordingly.
[0021] The outlet may be surrounded by a retaining wall projecting
from an underside of the container.
[0022] In exemplary embodiments, one or more of the fixed parts
includes a rib on an underside thereof.
[0023] Advantageously, the provision of a rib strengthens the fixed
parts such that, in use, they have increased resistance to the
force generated by the pressure of the product as it is dispensed.
This is particularly advantageous in the embodiments that include
the membrane, as the increased strength of the fixed parts compared
to the strength of the membrane helps to safeguard against the
fixed parts also breaking when the membrane is broken.
[0024] In exemplary embodiments, the movable parts are biased
towards the closed position such that when the dispensing pressure
is released, the outlet closes.
[0025] Advantageously, the biasing of the movable parts helps to
`cut off the flow of product when a dispensing operating is
complete.
[0026] According to a second aspect, there is provided a container
for product to be dispensed, the container having an outlet through
which product may be dispensed from the container, the outlet
comprising a plurality of movable parts, each movable between a
closed position and an open position, and wherein a wall projects
from an underside of the container, said wall being arranged for
limiting the movement of said movable parts.
[0027] Advantageously, the wall prevents the movable parts from
overextending during a dispensing operation. This helps to ensure
the desired shape of the outlet is maintained and reduces the risk
of the movable parts breaking off.
[0028] In exemplary embodiments, the wall is annular to said
outlet, e.g. defining a ring around the axis of dispensing. In
exemplary embodiments, the wall is continuous. In exemplary
embodiments, an inner surface of the wall is parallel to the axis
of dispensing (i.e. parallel with the central axis of the
outlet).
[0029] In exemplary embodiments, the outlet is configured to shape
product during a dispensing operation from the container.
[0030] In exemplary embodiments, the outlet includes fixed parts,
e.g. the outlet may consist of three fixed parts and three movable
parts. In exemplary embodiments, the outlet define a generally
star-shaped opening when the movable parts are in the open
position. The movable parts may include a projection on an internal
surface configured to create the desired shape of product e.g. a
star shape.
[0031] In exemplary embodiments, an inner surface of each movable
part includes two angled surfaces which meet at an apex.
[0032] In exemplary embodiments, the container is formed with a
recess in the outer surface thereof.
[0033] The container may further comprise at least one locking
mechanism configured to retain the movable parts in the closed
position with a retaining force until a predetermined pressure is
reached within the container. The movable parts may be configured
to overcome the retaining force of the locking mechanism and move
to the open position when a predetermined pressure is reached
within the container. The locking mechanism may be configured to
deform in order to permit the movable parts to move to the open
position when a predetermined pressure is reached within the
container. The locking mechanism may be a tab configured to retain
the movable parts in the closed position until the product is
dispensed. The tab may be located on the fixed parts, and arranged
to engage the movable part when the outlet is in the closed
condition.
[0034] In alternative embodiments, the outlet of the container
includes a membrane after manufacture of the container, configured
to retain the movable parts in a closed position with a retaining
force until the membrane is broken.
[0035] The membrane may be located between the fixed and movable
parts of the outlet and between adjacent movable parts, such that
when the membrane is broken, the movable parts are free to move to
an open position. The membrane may be formed of thinner material
than the fixed parts of the outlet, such that, in use, the membrane
breaks and the fixed parts remain unbroken.
[0036] In exemplary embodiments, one or more of the fixed parts
includes a rib on an underside thereof.
[0037] Advantageously, the provision of a rib strengthens the fixed
parts such that, in use, they have increased resistance to the
force generated by the pressure of the product as it is dispensed.
This is particularly advantageous in the embodiments that include
the membrane, as the increased strength of the fixed parts compared
to the strength of the membrane helps to safeguard against the
fixed parts also breaking when the membrane is broken.
[0038] In exemplary embodiments, the movable parts are hingedly
coupled with the container. The hinge may comprise a groove. The
groove may have at least one internal radius. The groove may have
two internal radii. The hinge may be defined by a groove which
defines an open channel, having opposing walls and a transition
wall therebetween. The joint between said walls may define a
radius. The hinge may have a thickened area in relation to the
remainder of the hinge. There may be a thickened area at or
adjacent to one or both ends of the hinge lengthways.
[0039] In exemplary embodiments, the movable parts are biased
towards the closed position.
[0040] The container may further comprise an upper part, intended
to move or deform to reduce the internal volume of the container
and cause the movable parts to move to the open position.
[0041] According to a third aspect, there is provided a method of
dispensing, comprising the steps of producing the container of the
first or second aspect, moulding the container with the movable
parts in an open position, displacing the movable parts to a closed
position after moulding, and providing at least one locking
mechanism to retain the movable parts in the closed position with a
retaining force until a predetermined force is applied to the
movable parts.
[0042] This simplifies the moulding operation compared to previous
methods, reducing the cost of manufacture, as well as removing the
need to provide a removable sticker or the like on the container
outlet to help contain the product.
[0043] In exemplary embodiments, the movable parts are configured
to overcome the retaining force of the locking mechanism and move
to an open position when a predetermined pressure is reached within
the container (i.e. when a threshold force applied to the movable
parts has been exceeded).
[0044] The locking mechanism may deform in order to allow the
movable parts to move to an open position when a predetermined
pressure is reached within the container.
[0045] The locking mechanism may be a tab that retains the movable
parts in the closed position with the retaining force after
completion of the moulding process. The tab may be located on the
fixed parts, arranged to engage the movable part when the outlet is
in the closed condition.
[0046] According to a fourth aspect, there is provided a dispensing
assembly comprising a plurality of containers according to the
second aspect, and a dispensing machine comprising a seating for
receiving one of said containers and supporting said container for
a dispensing operation, and a dispensing mechanism for applying a
force to said container when received in the seating for a
dispensing operation, wherein the seating includes a recess or
aperture having a diameter greater than the wall which projects
from the underside of the container.
[0047] Therefore, during a dispensing operation, the wall provides
a barrier between the outlet of the container and the seating of
the dispensing machine, helping to prevent product from
transferring to the seating during a dispensing operation, making
the machine more hygienic and reducing the need for a user to clean
the dispenser after each operation.
[0048] The dispensing mechanism may comprise a plunger or other
movable part intended to contact and deform the container,
decreasing the internal volume within the container, thereby
increasing pressure within the container, in order to cause product
to be expressed through the outlet of the container.
[0049] According to a fifth aspect, a mechanism is provided for
opening a container of the first or second aspect including a
membrane between the fixed and movable parts of the outlet, the
mechanism comprising a cup-shaped recess that generally corresponds
to the profile of the underside of the container, wherein the
recess includes a slot, groove, depression or channel in a bottom
surface that corresponds to a projecting wall on an underside of
the container, and wherein the recess defines a projection inboard
of said slot, groove, depression or channel, such that, in use,
when one of said containers is placed into the mechanism and a
force is applied to a top surface of the container, a bottom half
of the container sits in the recess, and a wall of the container
projects into 15 the slot, groove, depression or channel, such that
the membrane is broken by the projection, freeing the movable parts
of the outlet to move to an open position.
[0050] According to a sixth aspect, there is provided a method of
opening a container of the first or second aspect including a
membrane between the fixed and movable parts of the outlet, the
method comprising placing the container into the mechanism of the
fifth aspect and applying a force to a top surface of the container
such that the outlet of the container engages the projection of the
mechanism, breaking the membrane of the container.
[0051] In alternative embodiments, there is provided a method of
opening a container of the first or second aspect including a
membrane between the fixed and movable parts of the outlet, the
method comprising securing the container in place and applying a
force to the outlet of the container, breaking the membrane of the
container and freeing the movable parts of the outlet to move to an
open position.
[0052] According to a seventh aspect, there is provided a method of
performing a dispensing operation, comprising inserting a container
of the first or second aspect that includes a membrane between the
fixed and movable parts of the outlet into a seating, applying a
force to the container to break the membrane, freeing the movable
parts of the outlet to move to an open position, and applying a
force to the container to dispense product through the outlet.
[0053] In exemplary embodiments, the method comprises moving the
container to a dispensing location after the step of breaking the
membrane and before applying a force to the container to dispense
product.
[0054] In exemplary embodiments, the container is moved to a
breaking location after the container is inserted into the seating,
before a force is applied to the container to break the
membrane.
[0055] In exemplary embodiments, a force is applied to an outlet of
the container to break the membrane. In exemplary embodiments, the
outlet of the container is forced onto a projection in order to
break the membrane.
[0056] In exemplary embodiments, a force is applied to a top

DETAILED DESCRIPTION OF THE INVENTION
[0093] Referring firstly to FIG. 1, and an ice cream dispenser is
indicated generally at 10. The dispenser 10 includes a seating 12
configured to receive a container of product to be dispensed. The
dispenser 10 is configured to apply a load to a container received
on the seating 12, in order to extrude product from the
container.
[0094] The dispenser 10 is of the kind described in WO2011/036477,
although other forms of suitable dispenser are known in the art,
e.g. as marketed under the trade mark ONE SHOT.
[0095] An example of a container suitable for use in the dispenser
10 is indicated generally at 20 in FIGS. 2 and 3. The container 20
has an upper part 22 and a lower part 30. The upper part 22 has a
deformable section 24 with an upper surface 26, and a flange 28 for
locating the container on a seating 12 of the dispenser. The lower
part 30 is configured to nest in the seating 12, and includes a
flat base 32 at its lowest point. The base 32 is circular and has
an outlet 40 at its centre.
[0096] Typically, in use, a plunger within the dispenser is used to
push against the upper surface 26 of the deformable section 24,
causing it to move inwardly, thereby reducing the internal volume
of the container 20. This action causes product to be extruded
through 20 the outlet 40.
[0097] FIG. 4 shows the underside of the lower part 30 of a
container 10 for use with the apparatus FIG. 1, according to an
embodiment of the invention, in which the outlet is defined by a
plurality of parts 42, 44. As will be described in more detail
below, the parts 42 are movable between open and closed positions,
whereas the parts 44 are not hinged but are instead intended to
remain fixed in a `closed` position (e.g. extending orthogonally to
a central through axis of the outlet).
[0098] Accordingly, the outlet 40 has an open and a closed
condition, for dispensing and storing ice cream respectively. In
FIG. 4, the outlet 40 is shown in an open condition, wherein the
movable parts 42 are in an open position. In FIG. 6, the outlet 40
is shown in a closed condition, wherein the movable parts 42 are in
a closed position.
[0099] The movable parts 42 are hinged such that they can be
displaced outwardly from the lower container part 30 to an open
position, e.g. as illustrated in FIG. 4. The movable parts 42 are
naturally biased towards the closed position.
[0100] As will be described in more detail below, each movable part
42 has a complex shape, with multiple advantages.
[0101] In the open condition, product is shaped as it is dispensed
through the outlet 40. In particular, the movable and fixed parts
42, 44 cooperate to shape product as it is dispensed through the
outlet 40.
[0102] In the closed condition, each fixed part 44 partially
overlaps its adjacent movable parts 42, to provide a retaining
force against movement of the movable parts from their closed
position, e.g. as shown in FIG. 9. More particularly, the fixed
parts 44 have a tab 60 formed thereon to be elastically deformable,
such that the tab 60 may deform in order to permit the movable
parts 42 to pass when a predetermined force is applied to displace
the movable parts 42 from the closed to open position, or vice
versa, e.g. they `snap over` the tab on the fixed parts 44 when the
retaining force is overcome by the predetermined force during
dispensing.
[0103] A continuous wall 46 projects from the underside of the
container 10. The wall 46 defines a ring around the outlet 40,
co-axial with the outlet 40. It projects in a perpendicular
direction to the flat base 32 of the lower container part 30, i.e.
with an inner surface of the wall extending parallel to the central
axis of the outlet 40. The wall 46 prevents the movable parts 42
from overextending, reducing the risk of the movable parts 42
breaking off during a dispensing operation. The wall 46 may
cooperate with the movable parts 42 helping them to form a desired
shape of the outlet 40 in an open condition.
[0104] FIG. 5 shows a plan view of the lower container part 30 when
the outlet 40 is in the open condition. It can be seen how the
positioning and shape of the movable parts 42 and the fixed parts
44 creates a generally star-shaped opening 50.
[0105] The fixed parts 44 of the outlet 40 are generally triangular
having two free sides when the outlet is in an open configuration.
In the embodiment of FIGS. 4 to 10, the free sides are of unequal
length, i.e. defining one short free side 45 and one long free side
47. The short free sides 45 extend radially with respect to a
central axis of the outlet 40.
[0106] Each movable part 42 is moulded with a recess in its outer
surface, such that a projection 48 is created on an inner surface
of each movable part. When the movable parts 42 are located in the
open position, the projections 48 extend into the outlet 40,
and--in combination with the triangular shape of the fixed parts 44
(extending in a direction parallel and coincident with the flat
base 32)--serve to create the star-shaped opening 50, as can be see
clearly from FIGS. 4, 5 and 10.
[0107] FIG. 6 shows the lower container part 30 with the outlet 40
in a closed condition. The movable parts 42 are in the closed
position, wherein the tab 60 of each fixed part 44 overlaps each
movable part 42, retaining the movable parts 42 in the closed
position with a retaining force.
[0108] FIG. 7 shows a plan view of the lower container part 30 with
the outlet 40 in a closed condition. Here, the outline profile of
the movable parts 42 and fixed parts 44 can be seen most clearly.
As mentioned above, a hinge 52 (described in more detail below)
couples the movable parts 42 to the base 32. The hinge 52 permits
the movable parts 42 to move between open and closed positions.
[0109] Each movable part 42 has a free end 54, distal the hinge 52.
The free end 54 has a planar end surface 56 (shown more clearly in
FIG. 8). The end surface 56 is shorter in length than the hinge 52.
The end surface 56 is parallel with the hinge 52.
[0110] Each movable part 42 has two free sides 58, 59 extending
from the free end 54 to the hinge 52. The two free sides 58, 59 are
of unequal length, defining one long free side 58 and one short
free side 59. The two free sides 58, 59 of the movable parts 42
define a planar surface having a wedge-shaped profile, as can be
seen most clearly from FIG. 10.
[0111] The long free side 58 of each movable part 42 extends at an
acute angle between the hinge 52 and the end surface 56, and
extends radially with respect to a central axis of the outlet 40.
The end surface 56 is shorter in length than the long side 58. The
short free side 59 of each movable part 42 extends between the
hinge 52 and the end surface 56 in a direction perpendicular to the
hinge 52. The short free side 59 is longer than the end surface
56.
[0112] It can be seen from the plan view of FIG. 7 that when the
outlet 40 is in the closed condition, a portion of the long side 58
of a first movable part 42 is adjacent the end surface 56 of a
second movable part 42. Moreover, a portion of the sides 58, 59 of
the movable parts 42 is also adjacent respective sides of the fixed
parts 44 of the outlet 40. The short free side 58 of the movable
parts 42 is substantially the same length and the long free side of
the fixed parts 44.
[0113] Advantageously, the combination of long and short sides of
the movable and fixed parts has been found to provide an improved
seal within the container 10 when the outlet 40 is in the closed
condition, and also assists in a desirable shape-forming
configuration, for the ice cream being dispensed through the outlet
40.
[0114] FIG. 8 shows the outlet 40 in a partially open condition.
The shape of the end surface 56 and the side surface 58 of the
movable parts 42 can clearly be seen. The shape of the projection
48 can also be seen, this shape helping to create the generally
star-shaped opening 50 when the outlet 40 is in the open
condition.
[0115] FIG. 9 shows the outlet in the closed condition. It can be
seen more clearly how the fixed part 44 has a tab 60 on its inner
edge. The tab 60 has a rounded outside surface. The tab 60 is
elastically deformable when a predetermined force is applied to
it.
[0116] FIG. 10 shows the outlet in the open condition. In the open
condition, the movable parts 42 are prevented from excessive
movement by the wall 46. It shows clearly that the movable parts 42
have an inner face 70 arranged to project inwardly of the container
in the closed position (formed by the recess on the outer face 72).
More particularly, the inner face 70 of each movable part 42
includes two angled surfaces 74 which meet at an apex 76.
[0117] FIG. 11 shows a detailed cross section of the hinge 52. The
hinge 52 is a groove located between the base 32 and the movable
part 42. The groove defines a channel having a radially outer
surface 62 and a radially inner surface 64. Connecting the outer
and inner surfaces 62, 64 is a base or joint 66. The joint 66 is of
reduced cross-section, enabling the hinge to flex. The transition
between the outer surface 62 and the joint 66 defines a radius 67,
and the transition between the inner surface 64 and the joint 66
defines a radius 68. This configuration has been found to promote
flexure of the hinge without splitting during movement of the
movable part from a closed to open position.
[0118] Although not shown in the figures, to further discourage
splitting, the thickness of the hinge 52 may also vary along its
length. For example at either end, adjacent the fixed parts 44, it
may have an increased thickness e.g. the joint 66 may have an
increased depth at either end of the hinge. This would
advantageously increase the strength of the hinge at its end
regions and minimise the risk of tearing along the hinge 52.
[0119] The container 20 is manufactured by injection moulding. It
is moulded with the outlet 40 in a partially open condition as
illustrated in FIG. 8. The movable parts 42 are then moved to the
closed position. This can be done manually or automatically
immediately following the moulding operation. The movable parts 42
are retained in the closed position by the tabs 60 located on the
fixed parts 44.
[0120] In use, the container 20 is placed in the seating 12 of an
appropriate dispenser such as the one illustrated in FIG. 1. Upon
the application of an extrusion force, e.g. via a plunger or like
device on the dispenser, the internal volume within the container
20 is decreased, thereby increasing the internal pressure. At a
predetermined pressure, the retaining force of the tabs 60 is
overcome. The tabs 60 elastically deform allowing the movable parts
42 to move to the open position. The outlet 40 is therefore in an
open condition, creating a star-shaped opening 50. Product extrudes
through the outlet 40. The product takes the shape of the opening
50 as it passes through, so has a star-shaped cross-section as it
exits the outlet 40.
[0121] During the operation, the wall 46 prevents the movable parts
42 from overextending, keeping the star-shape as desired and
reducing the risk of the movable parts 42 breaking off during the
operation. At the end of the operation, the natural bias of the
movable parts 42 towards the closed position helps to cut off the
stream and `crimp` the product.
[0122] The diameter of the wall 46 is lower than the diameter of a
recess (not shown) in the seating 12 of the dispensing machine 10.
The wall 46 advantageously provides a barrier between the outlet 40
and the seating 12, preventing product from transferring to the
seating 12 during dispensing, making the machine more hygienic and
reducing the need for a user to clean the dispenser after each
operation.
[0123] The container 20 is nestable with other containers of the
same dimensions and the same type so that they can be filled with
product on high-speed filling machines. A base support may be
required to apply pressure against the assembled sections whilst
the product is being filled and the lid is applied and closed.
[0124] It will be appreciated that further variations can be made
without departing from the scope of the invention. For example, the
tabs 60 could be in a different location such as attached to the
wall 46 or the movable parts 42.
[0125] FIG. 12 shows a plan view from the underside of another
container 80, which is substantially the same as the container of
FIGS. 2-11, but is moulded with the outlet in a closed condition. A
land 82 is formed between the movable parts 42. The land 82 is of a
reduced material thickness, suitable to form a line of weakness
capable of breaking under typical extrusion pressures for the
product in question. Each land 82 is a continuation of a line of
weakness (formed by a region of reduced material thickness)
extending between the movable and fixed parts 42, 44. Hence, the
outlet is moulded closed, and is capable of breaking open during a
dispensing operation, in order to adopt a configuration as shown in
FIGS. 4 & 10.
[0126] FIG. 13 shows a perspective view of another container 90,
which is substantially the same as the container of FIG. 12, but
with a modified outlet 100. FIG. 14 shows plan view from above the
container 90. It can be seen that the outlet has movable parts 102
and fixed parts 104.
[0127] To strengthen the fixed parts 104, each fixed part 104
includes a strengthening rib 108 on an underside thereof. The rib
108 extends substantially along the length of the fixed part, from
an annular wall 110 (surrounding the outlet and projecting
outwardly from the bottom surface of the container 90) to a
location proximal (but spaced from) a free end of the fixed part.
As can be seen from FIG. 14, the rib 108 extends from a point
generally midway along the arc of the section of annular wall 110
at the non-free end of the fixed part and in the direction of the
tip of the free end of the fixed part. The height of the rib tapers
from a maximum adjacent the wall 110 to a minimum at the distal end
of the rib. The maximum height of the rib may correspond to the
height of the wall, for example, whereas the rib may taper to zero
height as a minimum, as shown in FIG. 14. The rib 104 may be
applied to any embodiment of container described herein, but is of
particular advantage to those embodiments in which the movable
parts are designed to break open from a closed condition.
[0128] FIG. 15 shows a detailed perspective view of the outlet 100
in a closed condition. Only one movable part 102 is shown for
clarity. FIG. 16 shows a detailed perspective view of the outlet
100 an open condition, also with only one movable part 102 shown,
for clarity. It can be seen that each rib 108 is triangular, with a
first side projecting from the annular wall 110, a second side
projecting from the underside surface of the fixed part 104, and a
third side connecting the first and second sides.
[0129] Each movable part 102 is substantially the same as the
movable parts 42 of the container of FIGS. 2 to 12, except with a
modified end surface 112. As can be seen most clearly from FIGS. 15
and 16, the end surface 112 is substantially semi-circular, and
projects outwardly to a greater extent than the end surface 56 of
the containers of FIGS. 2 to 12.
[0130] The outlet 100 is moulded in a closed condition and the land
106 is capable of being broken open prior to a dispensing operation
(described in more detail below), in order to free the movable
parts 102 to move outwardly from the container 90 under pressure
from the extrusion of product, to adopt an open configuration as
shown in FIG. 16. It can be seen how the provision of the ribs 108
can help to reduce the risk of the fixed parts 104 also breaking
when the land 106 is broken prior to a dispensing operation.
[0131] Although particularly suited for a frozen confection, e.g.
ice cream, sorbet, frozen yoghurt, the outlet configuration of a
plurality of movable and fixed parts shown and described herein
could be used with a range of different types of container,
provided that the container is of a kind intended for use with a
force applied to the container in order to extrude product through
the outlet.
[0132] FIGS. 17a to 17c show a method of breaking the land 106 of
the container 90 in order to free the movable parts to move to an
open condition. A mechanism 120 is shown in cross-section, suitable
for causing the breaking of the land 106. The mechanism 120
includes a cup-shaped recess 122 that generally corresponds to the
outer surface of the lower part of the container 90. The recess 122
includes a groove 124 in a bottom surface. The groove 124 is
annular and located centrally of the recess, in order to correspond
to the position of the annular wall 110 of the container 90, such
that the wall 110 can project into the groove 124 when the
container is located in the recess (described in more detail
below). The groove 124 defines a projection 126, inboard of the
groove 124. The upper end of the recess defines a shoulder 130.
[0133] Looking at FIG. 17a, to operate the mechanism 120, firstly
the container 90 is placed in the recess 122. A force is applied to
a top surface of the container 90 as shown in FIG. 17b, causing the
container to move downwardly into the recess 122, whereupon the
annular wall 110 moves into the groove 124. This causes the outlet
100 to be brought into engagement with the projection 126, causing
the movable parts 102 to move inwardly, breaking the land 106 (see
FIG. 17c).
[0134] The lid of the container engages the shoulder 130, limiting
movement of the container and, more specifically, the movable parts
102, to reduce the risk of them breaking off. The container 90 can
then be removed from the mechanism 120, whereupon the outlet 100 is
free to move to the open condition.
[0135] Alternatively, although not shown in the Figures, the land
106 of the container 90 could be broken in a different way. For
example, the container 90 could be simply secured in a ring-type
seating before a surface of an actuating member is made to engage
the outlet 100, applying a force to break the land 106. The outlet
of the container could also be pushed into engagement with some
other form of projection dimensioned to allow the movable parts to
flex inwardly and cause fracture of the land 106.
[0136] FIGS. 18a to 18d show a method of performing a dispensing
operation using the container 90 of FIGS. 13 and 14. FIG. 18a shows
a dispensing apparatus 140 in a first condition, for receiving a
container 90. It can be seen that a seating 142 is provided for
accepting the container 90. It is shaped to generally correspond to
the external profile of the underside of the container 90, but
includes an aperture 144 at a bottom end, such that when the
container 90 is seated, the outlet 100 is exposed. The seating 142
is movable relative to the body 141 of the apparatus. This can be
achieved by providing the apparatus 140 with an actuating member in
communication with the seating 142 to move it between different
positions (the different positions are described in more detail
below), or by providing the apparatus 140 with a rotating member to
translate the container 90 between different positions. In use, a
container 90 is inserted into the seating 142 when the seating is
at a first position, such that the outlet 100 is located within the
aperture 144 of the seating 142. The seating 142 is subsequently
moved to a second position relative to the body 143 of the
apparatus, shown in FIG. 18b.
[0137] FIG. 18b shows the apparatus 140 in a second condition, for
breaking the land 106 of the container 90, to enable the movable
parts 102 to move to an open condition. It can be seen that the
seating 142 has been moved to a second position relative to the
body 143, from right to left along the body 141 of the apparatus
142 in FIG. 18b. At this position of the seating 142, the aperture
144 of the seating 142 is located adjacent an actuating member 146
of a breaker mechanism 148. Therefore, the actuating member 146 can
be moved, in use, to engage the outlet 100 of the container 90 in
the seating 142. The force of the actuating member 146 acting on
the outlet 100 breaks the land 106.
[0138] FIG. 18c shows the apparatus 140 in a third condition, after
the land 106 is broken, for dispensing product from the container
90. It can be seen that the seating 142 has been moved to third
position relative to the body 141. The third position is
intermediate the first and second positions of the seating 142,
e.g. in the centre of the apparatus as shown in FIGS. 18a-d. The
apparatus 140 includes a dispensing head 150, arranged to engage
the top surface of the container 90 in use. The dispensing head 150
is a piston or other actuating part that can apply a force to the
top surface of the container 90 during a dispensing operation,
compressing the upper part of the container 90 and increasing the
pressure within the container 90. In use, when the pressure within
the container 90 reaches a predetermined level, the movable parts
102 of the outlet 100 pivot outwardly from the container 90, and
product is extruded through the outlet 100.
[0139] FIG. 18d shows the apparatus 140 in a fourth condition, for
disposing of the container 90 after a dispensing operation. In this
condition, the seating 142 remains in the third position. The
container 90 is picked up by the dispensing head 150 (e.g. via a
suction 20 device), and translated to a disposal area 152 of the
apparatus 140, where it is released. Alternatively, a separate
mechanism may pick up the container 90 after a dispensing operation
and move it to the disposal area 152. The disposal area 152 is
located on the left side of the apparatus as shown in FIG. 18d, but
may be located in another part of the apparatus, for example the
rear of the apparatus 140. The depleted containers 90 are stored in
the disposal area 152 of the apparatus 140, but alternatively they
may be ejected from the apparatus 140 to be stored elsewhere.
[0140] FIGS. 19 and 20 show a vending machine 160 for dispensing
portions of ice cream or other frozen confection from the container
90 of FIGS. 13 and 14. FIG. 19 is a cut-away front view of the
machine. The vending machine has a dispensing area 162 where
product is dispensed from the containers 90, and a storage area 164
where containers containing product are stored.
[0141] FIG. 20 shows a cut-away plan view of the vending machine
160. In the dispensing area 162, is a rotatable drum 166. The drum
contains four apertures 168, distributed evenly around the drum
166, each aperture 168 being suitable for seating the container 90.
The apertures 168 are circular but could be any suitable shape for
housing the container 90. In use, a container 90 is seated in an
aperture 168 of the drum 168 at a first location 170. A breaker
mechanism 148 is located at the first location, for breaking the
land 106 of the outlet 100 of the container 90, as described in
more detail above. Therefore, in use, the container 90 is seated in
an aperture 168 of the drum at the first location to be secured in
place subsequent to the actuating member 146 of the breaker
mechanism 148 engaging the outlet of the container to break the
land 106.
[0142] The drum 166 is then rotated by 90 degrees in order to move
the container 90 from the first location 170 to a second location
172, where a dispensing head 150 applies a force to the container
90, dispensing product as described in more detail above.
[0143] The drum is then rotated by another 90 degrees in order to
move the container 90 from the second location 172 to a third
location 174, before the drum is rotated another 90 degrees in
order to move the container 90 from the third location 174 to a
fourth location 176. At the fourth location 176, the depleted
container 90 is disposed of.
[0144] The storage area 164 includes a magazine 180 of containers
90 containing product, to be used to refill the aperture 168 at the
first location 170 after every time the drum 166 rotates. The
magazine 180 is a rotatable carousel and includes six stacks 182 of
containers 90. Each stack is arranged vertically and includes
multiple containers 90. When a container 90 is removed from a stack
182, the remaining containers 90 fall downwardly under gravity to
take the place of the removed container 90. The magazine 180 is
arranged such that the bottommost container 90 of one stack 182 is
located adjacent the first location 170. Therefore, in use, a
container 90 can be transferred from the magazine 180 to the drum
166. This can be achieved with a suction mechanism or other
mechanical release (not shown). When a stack 182 is depleted, the
magazine 180 can rotate to present another stack. Therefore, at
least one stack is always coaxial with the aperture 168 at the
first location 170.
[0145] In exemplary embodiments, the vending machine 160 includes a
user interface (e.g. of the kind indicated generally at 200 in FIG.
1) for a user to select product to be dispensed. The vending
machine will further include a processor (illustrated figuratively
by the box 202 of FIG. 1, though it will be appreciated that the
processor 202 may be located either within the vending machine or
external of it) configured for automating a dispensing operation
according to a user selection via said user interface 200. For each
user selection, a container 90 of product will be delivered from
said storage location 164, said breaker mechanism 148 will then be
used to break the outlet land 106, before the dispensing head 150
is used to apply a load to the container 90 in order to dispense
product from said outlet 100. As described above, the container 90
may then be disposed of. The vending machine 160 may include a
mechanism for receiving payment (not shown) in order to authorise a
dispensing operation according to a user selection, e.g. for
receiving coins, monetary notes, tokens, credit or debit card
payment or other known forms of payment.
[0146] Alternatively, one or more of the mechanisms described
herein may be incorporated into a dispensing apparatus (as opposed
to a vending machine) configured for manual operation rather than a
wholly automated process based on a user selection and or user
payment to the machine. For example, the dispensing apparatus may
include a seating for receiving a container of the kind described
herein and having a land 106 between fixed and movable parts of the
outlet 100 (i.e. intended to be broken prior to a dispensing
operation), wherein the apparatus includes a breaker mechanism 148
and a dispensing head 150, such that a container as set forth can
be placed in the seating, and wherein, in response to a human
operator command (e.g. made via a button or other suitable user
interface on the apparatus), the breaker mechanism 148 will act to
break the land 106, before the dispensing head 150 acts on the
container to express product through the outlet. The apparatus may
be of a kind where the container needs to be placed in the seating
by a human operator, or may be of a kind including a storage area
provided with a stock of sealed containers of the kind set forth,
which can be automatically delivered to or stored in an appropriate
seating forming part of the apparatus, for use in a dispensing
operation in response to a human operator command.
[0147] While the invention has been described in connection with
what is presently considered to be the most practical and preferred
embodiments, it is to be understood that the invention is not to be
limited to the disclosed embodiments, but on the contrary, is
intended to cover various modifications and equivalent arrangements
included within the spirit and scope of the appended claims.
