Description
CROSS-REFERENCE
[0001] This application claims priority to U.S. Provisional Patent
Application No. 61/421,192, filed on Dec. 8, 2010, which is
entirely incorporated herein by reference.
BACKGROUND OF THE INVENTION
[0002] Packaging used for containing liquids can generate large
amounts of waste. In some cases, packaging used for containing
liquids can be recycled. Packaging used for containing liquids has
been described in PCT Publication No. WO/2007/0066090, which is
herein incorporated by reference in its entirety.
[0003] Traditionally, many beverages such as wine, beer and milk
have been supplied in glass bottles. The glass used to make these
bottles may itself be recycled. However, the energy required to
make the bottles is high. Also, the weight of the resulting
packaging is high, increasing the amount of energy required to
transport the products. While the glass can be recycled, this does
require that the bottles are separated from other waste, for
example by users separating the glass bottles from other household
waste for collection. Therefore, it is often the case that glass
bottles are disposed of with other waste. In this case, the glass
bottles may be disposed of in a landfill site. This is a problem
since, unlike some other forms of waste, glass is not
biodegradable.
[0004] More recently, it has become common to use bottles made from
plastics, such as PET or HDPE, for liquid such as water, juice,
carbonated drinks, or milk. In this case, it is common for the
bottles to be formed from virgin, i.e. non-recycled, material to
ensure that the liquid contained within the bottle is not
contaminated as could be the case if the containers were formed
from recycled material. While the material itself could be recycled
if separated from other waste, as with glass bottles this
frequently does not occur due to the need for the waste producer,
such as a householder, to separate the containers from other waste
material. Again, if the container is disposed of in a landfill site
or the like, the bottle is not biodegradable. Also, bottles take up
a volume larger than that of the material itself due to their
hollow, rigid, structure, and therefore take up an excessive amount
of space in a landfill site.
[0005] It has also been proposed to package liquid in laminated
cardboard containers, for example in containers marketed by Tetra
Pak. In this case, the cardboard from which the body of the
container is formed may be virgin or recycled material. The
cardboard is laminated with a waterproof coating. This ensures that
the container is able to hold liquid and also acts as a barrier
between the liquid and the cardboard, which can prevent
contamination of the liquid from the cardboard. This is especially
needed where the cardboard is formed from recycled material. A
problem with such packages is that they are difficult to recycle,
and the waterproof coating prevents them fully decomposing. The
problem is exacerbated when a plastic dispensing nozzle or cap is
formed as part of the package for dispensing the contents. This is
another component that would need to be separated before the
container can be recycled or parts of this be allowed to
decompose.
[0006] In some countries, liquid such as milk is packaged in bags.
However, these bags have little structural stability, and therefore
are difficult to transport and to stack on shelves. They are often
not re-sealable, making them hard to hold and carry.
[0007] It is known to package wine in boxes. These comprise a box
body, typically formed of laminated cardboard, which provides the
structure for the package. A bag is provided within the box, the
wine being contained within the bag. A dispensing tap is often
connected to the bag, and when in use is arranged to protrude
through a side opening in the box. In such instances, the spout is
made to protrude or hang outside of the box for dispensing. The
weight of the liquid is usually distributed along the box bottom
and is not supported by the dispensing tap protruding from the box.
For the efficient disposal of such a container, each of the parts
made from different materials would be also separated, namely the
bag from the box, the dispensing tap from the bag, and the
lamination from the cardboard forming the box. This separation of
packaging components is difficult and prevents such packages from
being disposed of or recycled efficiently.
[0008] Furthermore, in some cases bottles or other liquid
containers contain additional, separable components that do not
make it into a recycling bin. For example, loose caps, straws, and
plastic tamperproof or tamper-evident devices can contribute to
overall litter in the environment. Even if bottles make it into a
recycling bin or garbage can, their caps or other types of closures
often end up as general litter.

[0062] In an embodiment, the skeleton shell can comprise any
structural body that provides an enclosure and support to a liquid
holding bag (or vessel). The weight of the liquid holding vessel
can be supported by the skeleton. In some cases, the weight of the
liquid holding vessel can be supported at a neck area only, which
is connected to the skeleton. The skeleton can be formed of any
material suitable for providing structural support. In some
configurations, the skeleton can have sufficient structural
rigidity to provide a gripping or grasping area for a user's hand
and/or to prevent compression of a liquid holding vessel contained
within the skeleton. The gripping or grasping area can be
positioned about the liquid holding vessel, such that the liquid
holding vessel is between two points on the gripping or grasping
area. In such a configuration, the liquid holding vessel can
exhaust its contents naturally as the liquid holding vessel
collapses. A fitment, described herein, may also be designed to
facilitate gripping or grasping of a container described herein.
The fitment can have grooves, reinforced surfaces, or friction pads
to facilitate gripping or grasping.
[0063] In an embodiment, the material used to form the skeleton can
be food-grade material. In another embodiment, the materials used
to form the skeleton are not food-grade materials.
[0064] In an embodiment, the material used for forming the skeleton
need not be food-grade, as the liquid holding vessel can prevent
contact of any liquid contained within the liquid holding vessel
with the skeleton during storage of the liquid or during dispensing
of the liquid. The skeleton can comprise any low embodied energy
material, such as recyclable materials and/or biodegradable
materials, such as molded fiber or pulp or paper. For example, the
skeleton may comprise 100% post-consumer fiber or pulp feedstock.
In another example, the skeleton may comprise 100% recycled
corrugated fiberboard and newspaper. The skeletons or other
materials described herein can include virgin pulp fiber. The
skeleton can comprise type-2 molded fiber, type-2A thermoformed
fiber, type-3 thermoformed fiber, type-4 thermoformed fiber, molded
fiber, X-RAY formed fiber, infrared formed fiber, microwave formed
fiber, vacuum formed fiber, structural fiber, sheet stock, recycled
plastic or any other structural material. Any of the materials that
may be used to form the skeleton may be used in any of the
embodiments described herein. Any discussion of pulp may also apply
to any of the materials (e.g., fiber molding, natural fibers,
biodegradable or compostable materials) that may be used to form a
skeleton or skeleton shell.
[0065] The skeleton can be formed from one or more sheets of
material that are laminated, folded or glued together. The sheets
of material can comprise hinges, joints, creases, interlocks,
flanges, or flaps for simplified folding of the sheets to form the
skeleton.
[0066] In some embodiments of the invention, the skeleton can
comprise a fiber or pulp-molded body. The fiber and pulp-molded
body can be a hollow shell, a clam shell, a two-piece shell, a
multi-piece shell, or a combination thereof. The hollow shell can
be a one-piece fiber or pulp-molded body where a liquid holding
vessel is placed on the interior of the hollow shell through an
opening of the hollow shell. The clam shell can be a fiber or
pulp-molded body with a hinge that is folded around a liquid
holding vessel. The hinge can be located on any side of the clam
shell. For example, the hinge can be along a bottom edge or side
edge of the skeleton. The clam shell and/or the liquid holding
vessel can have flanges and/or interlocks for securing the clam
shell to or around the liquid holding vessel. The two-piece shell
can comprise two fiber or pulp-molded body pieces that can enclose
a liquid holding vessel. The two pieces can have interlocks or
flanges for securing the pieces to each other. The two body pieces
can be separate (un-hinged) or joined (e.g., hinged). The two-piece
shell can be a two-part assembly of two cup-like parts that are
assembled to one another with their open ends facing one another
that can enclose a liquid holding vessel. A multi-piece shell can
comprise a fiber or pulp-molded body piece with a hinge or a
two-piece fiber or pulp-molded body combined with a belly band
and/or an end cap for securing the multi-piece shell in a closed
form around a liquid holding vessel. Pieces of the skeleton can be
held in place by an adhesive, a label, a mechanical deformation, or
any other means known to those skilled in the arts.
[0067] The skeleton can be shaped for incorporation of functional
features. In some embodiments of the invention, the skeleton can
comprise openings or cut-outs. The openings or cut-outs can be
located on any side or surface of the skeleton. The openings or
cut-outs can provide multiple functions. These functions can
include reducing the amount of material used to form the skeleton,
reducing the weight of the skeleton, allowing for viewing of the
contents of the container, allowing for the positioning of
stiffening rib features, retaining an interlock feature from
another piece of the skeleton, providing features for enhancing the
ability to grasp the skeleton, providing features for separation
from the liquid holding vessel, and increasing the ability to
collapse or compress the skeleton. The openings or cut-outs can be
formed during molding of the skeleton, or can be die-cut or
water-cut after molding of the skeleton.
[0068] Reference will now be made to the figures, wherein like
numerals can refer to like parts throughout. It will be appreciated
that the figures are not necessarily drawn to scale.

The fitment 230 can include registration features for mating with
registration features of each of the first and second enclosing
members 205a and 205b. The fitment 230 can include one or more
flanges for coming in contact with the skeleton shell 205. In an
embodiment, the fitment 230 is integral with the spout.
Drain-Back Pour Spouts
[0074] In another aspect of the invention, a drain-back pour spout
is provided, the drain-back pour spout configured to provide for
the flow of liquid out of a liquid holding bag in fluid
communication with the drain-back pour spout, and enabling fluid to
drain back into the liquid holding bag. The drain-back pour spout
can advantageously prevent the loss of any unused liquid, which can
occur around the circumference of an opening of a container.
[0075] With reference to FIG. 4, a drain-back pour spout 300 is
shown, in accordance with an embodiment of the invention. The spout
300 includes a cap 305, a pour spout 310, threads 315 for securing

detergent). The top flange 330 is configured to rest adjacent a top
portion of a neck of a skeleton shell. In an embodiment, the top
flange 330 can be attached to the top portion of the neck of the
skeleton shell. In another embodiment, the bottom flange is
configured to attach to a liquid holding bag (e.g., the liquid
holding bag 225 of FIG. 3C).
[0076] In an embodiment, the top flange 330 can be configured to
attach to or rest against a top portion of a skeleton shell, such
as the top portion of a neck portion of the skeleton shell. In
another embodiment, the top flange 330 can be configured to be
enclosed by a top portion of a skeleton shell. In another
embodiment, the bottom flange 325 can be configured to attach to or
rest against a top portion of a skeleton shell, such as the top
portion of a neck portion of the skeleton shell. In another
embodiment, the bottom flange 325 can be configured to be enclosed
by a top portion of a skeleton shell.
[0077] In an embodiment, the bottom flange 325 can be attached to a
liquid holding bag. In another embodiment, the bottom flange 325
can be unitary or integral with a liquid holding bag. In another
embodiment, the bottom flange 325 can be neglected, and a liquid
holding bag can be attached to or integral with a bottom portion of
the spout 300.
[0078] With continued reference to FIG. 4, the spout 300 can
include a single registration feature 320 or a plurality of
registration features angularly disposed about the spout 300. In an
embodiment, the spout 300 can include a single registration feature
320. In another embodiment, the spout can include 2, or 3, or 4, or
5, or 6, or 7, or 8, or 9, or 10 registration features, the
registration features disposed about the circumference of the spout
300. In another embodiment, the spout 300 can be attached to a
figment having a single registration feature 320 or a plurality of

single registration feature 320. In another embodiment, the spout
can be attached to a fitment having 2, or 3, or 4, or 5, or 6, or
7, or 8, or 9, or 10 registration features, the registration
features disposed about the circumference of the fitment.
[0079] The registration features can be configured to mate with
registration members of a skeleton shell (e.g., registration
members 220 of FIG. 3A). The mating of the registration features
and the registration members can prevent the spout 300 from
rotating while a user rotates the cap 305. This can advantageously
protect against a liquid holding bag from losing contact with the
bottom flange 325.
[0080] FIG. 5 illustrates a drain-back pour spout (also "pour back
spout" herein) 400 mounted on a neck portion of a skeleton shell
405, in accordance with an embodiment of the invention. The
drain-back pour spout 400 includes an inner tube 401 and an outer
tube 402, the outer tube 402 circumferentially enclosing the inner
tube 401. The outer tube is at least partially defined by the inner

[0081] FIGS. 6A and 6B show a pour back spout 500, in accordance
with an embodiment of the invention. In an embodiment, the pour
back spout is attached to a fitment. In another embodiment, the
pour back spout is attached to the a liquid holding bag for holding
or storing a liquid, such as a detergent.
[0082] FIG. 6A is a schematic side view of the pour back spout 500
with a first protrusion 505 extending beyond a second protrusion
510. FIG. 6B shows a top view of the pour back spout 500. The pour
back spout 500 can include an opening 515 surrounded by the first
protrusion and the second protrusion. The first protrusion and
second protrusion can be connected by an apron. The second
protrusion 510 of the pour back spout 500 can be connected to an
upper shoulder or flange 520 that can extend orthogonally away from
the second protrusion 510. A lower shoulder or flange 525 is
disposed below the upper shoulder or flange 520. The upper shoulder
520 and lower shoulder 525 can be part of a fitment.
[0083] In some embodiments, a pour back spout can have an opening
(or gap) 530 surrounded by a first protrusion and a second
protrusion. The opening can allow fluid to pass through the spout.
In some embodiments, a liquid held within a liquid holding bag can
be poured out of the container through the opening in the spout.
The opening 530 can be disposed in an apron of the pour back spout
505, the apron comprising a space between the first protrusion 505
and the second protrusion 510.
[0084] In some embodiments, the first and second protrusions can be
arranged concentrically so that the first protrusion is at least
partially surrounded by the second protrusion. In some embodiments,
the first and second protrusions can be arranged so that they are
not concentric, but that the first protrusion is still at least
partially surrounded by the second protrusion. A gap can be
provided between the first and second protrusions. In an
embodiment, the gap can be defined by the first and second
protrusions. The gap can be configured to capture liquid and drain
the liquid back to a liquid holding bag in fluid communication with
the pour back spout. In some embodiments, an apron can connect the
first and second protrusions. The apron can be provided between the
first and second protrusions, at a lower (or bottom) portion of the
first and second protrusions. The apron can be in fluid
communication with a fluid passageway back to the liquid holding
bag though the opening 530.
[0085] With continued reference to FIG. 6A, the first protrusion
505 can have a rounded shape. Alternatively, the first protrusion
505 can have one or more corner or pointed portions. The first
protrusion may have a cylindrical shape. In an embodiment, the
first protrusion 505 can completely surround the opening 515. In
another embodiment, the first protrusion 505 can partially surround
the opening 515. In another embodiment, the first protrusion 505
can extend 360 degrees around the opening. In another embodiment,
the first protrusion 505 can partially surround the opening 515.
The first protrusion 505 can extend partway around the opening 515.
In some embodiments, the first protrusion 515 can extend up to
about 30 degrees, or 45 degrees, or 60 degrees, or 90 degrees, or
120 degrees, or 150 degrees, or 180 degrees, or 270 degrees around
the opening 515.
[0086] In an embodiment, the first protrusion 505 can be
circumferentially symmetrical about the opening 515. In another
embodiment, the first protrusion 505 can extend by the same length
(symmetrical) or varying lengths (asymmetrical) around the opening
515. In some embodiments, the first protrusion 505 can be contoured
or curved around the opening 515.
[0087] In an embodiment, the second protrusion 510 can have a
rounded shape. Alternatively, the second protrusion 510 can have
one or more corner or pointed portions. The second protrusion 510
can have a cylindrical shape. In some embodiments, the second
protrusion 510 can have the same shape as the first protrusion 505.
Alternatively, the second protrusion 510 can have a different shape
than the first protrusion 505. The cross sectional shapes of the
second protrusion 510, first protrusion 505, and opening 515 can be
the same or different. In some embodiments, the second protrusion
510 can completely surround the opening 515. The second protrusion
510 can extend all the way around the opening 515. In another
embodiment, the second protrusion 510 can extend 360 degrees around
the opening 515. In another embodiment, the second protrusion 510
can partially surround the opening 515. The second protrusion 510
can extend partway around the opening 515. In some embodiments, the
first protrusion 515 can extend up to about 30 degrees, or 45
degrees, or 60 degrees, or 90 degrees, or 120 degrees, or 150
degrees, or 180 degrees, or 270 degrees around the opening 515. In
an embodiment, the second protrusion 510 can include threading to
accept a cap (see, e.g., FIGS. 4 and 7A).
[0088] In an embodiment, the second protrusion 510 can be
circumferentially symmetrical about the opening 515. In another
embodiment, the second protrusion 510 can extend by the same length
(symmetrical) or varying lengths (asymmetrical) around the opening
515. In some embodiments, the second protrusion 510 can be
contoured or curved around the opening 515.
[0089] The second protrusion 510 can protrude relative to a surface
that the pourback (also "pour back" herein) spout 500 is affixed
upon. For example, if the pourback spout 500 is connected to a
fitment that is mated to a shell, the second protrusion 510 can
protrude relative to the surface the shell. The second protrusion
510 protrudes relative to an apron connecting the first and second
protrusions 505 and 510, respectively, and a gap can be provided
between the first and second protrusions. The apron can be
depressed relative to the surface of the shell. In an embodiment,
the second protrusion 510 can extend at least some distance beyond
the shell.
[0090] In an embodiment, the first protrusion 505 can be taller, or
at the highest point protrude more than, the second protrusion 510.
In an embodiment, the first protrusion 505 can be shorter or at the
highest point protrude less than the second protrusion 510.
Alternatively, the first protrusion 505 and the second protrusion
510 can be about the same height.
[0091] In an embodiment, the pourback spout 500 can have a vertical
axis that can be perpendicular with respect to a bottom base of a
container having the pourback spout 500. When the pourback spout
500 is at an upright orientation, the vertical axis can also be
upright. The first protrusion 505 can be substantially parallel to
the pourback spout 500. The first protrusion 505 can be parallel to
the vertical axis. Alternatively, the first protrusion 505 can be
angled inwards toward the center of the opening 515, outwards away
from the center of the opening 515, or any combination thereof. The
second protrusion 510 can be angled straight up relative to the
pourback spout 500. The second protrusion 510 may be parallel to
the vertical axis. Alternatively, the second protrusion 510 may be
angled inwards toward the center of the opening 515, outwards away
from the center of the opening 515, or any combinations thereof.
The first and second protrusions 510 may be angled or not angled to
the same degree relative to the vertical axis. Alternatively, they
may be angled or not angled to different degrees relative to the
vertical axis.
[0092] In an embodiment, the first protrusion 505 and the second
protrusion 510 can be concentrically arranged so that the first
protrusion 505 has a smaller cross-sectional radius than the second
protrusion 510. The first and second protrusions 505 and 510 can be
concentrically arranged so that the center of the cross-sectional
shape defined by the first protrusion 505 is the same as the center
of the cross-sectional shape defined by the second protrusion 510.
In some embodiments, the first and second protrusions 505 and 510
can be almost concentrically arranged so that the center of the
cross-sectional shape defined by the first protrusion 505 slightly
offset from the center of the cross-sectional shape defined by the
second protrusion 510. The first and second protrusions 505 and 510
need not be concentrically arranged and the center of the
cross-sectional shape defined by the first protrusion 505 can be
substantially offset from the center of the cross-sectional shape
defined by the second protrusion 510.
[0093] In an embodiment, the second protrusion 510 may surround at
least a portion of the first protrusion 505. In some embodiments,
the second protrusion 510 may completely surround the first
protrusion 505. The second protrusion 510 can completely encircle
the first protrusion 505 and the opening 515. Alternatively, the
second protrusion 510 can surround the first protrusion 505 without
completely surrounding the opening 515 when the first protrusion
505 does not completely surround the opening 515. In some
embodiments, the second protrusion 510 may extend around the
opening 515 a larger number of degrees than the first protrusion
505. Alternatively, the second protrusion 510 can extend around the
opening 515 the same or a fewer number of degrees than the first
protrusion 505. In one example, the first protrusion 505 can only
extend partway around the opening 515, forming a tip, and the
second protrusion 510 may form a rim that completely surrounds the
opening 515 and the tip.
[0094] In an embodiment, a gap can be provided between the first
and second protrusions 505 and 510. The first and second
protrusions 505 and 510 can be connected by an apron, that also
forms the bottom of the gap. In some embodiments, the apron can be
level all the way around the opening 515. For example, the apron
bottom that goes around between the second protrusion 510 and the
first protrusion 505 may have the same depth all the way around.
Alternatively, the apron may have varying depths. For example, the
apron can be slanted so that a portion of the apron is deeper than
at other portions. In an embodiment, the deeper portion of the
apron can be configured to direct a liquid into the opening 515 of
the pourback spout 500 when the pourback spout 500 is at an upright
angle. The gap between the first and second protrusions 505 and 510
may have the same dimensions all the way around the opening 515, or
may vary around the opening 515. In some embodiments, a larger gap
can be provided at some angles around the opening 515 of the
pourback spout 500 than at other angles. The gap may have any
dimensions. For example, the distance of the gap between the first
protrusion 505 and second protrusion 510 can be greater than, less
than, or about 3% of the diameter, 5% of the diameter, 7% of the
diameter, 10% of the diameter, 12% of the diameter, or 15% of the
diameter of the second protrusion 510.
[0095] In some embodiments, the first protrusion 505, second
protrusion 510, and apron can be integrally formed as a single
piece. The inner wall of the second protrusion 510, the outer wall
of the first protrusion 505, and the apron can delineate a dip
between the first and second protrusions 505 and 510. The first
protrusion 505, second protrusion 510, and apron do not move
relative to one another.
[0096] In some embodiments, the first protrusion 505 can be a pour
tip. The pour tip can be configured to receive a liquid through the
opening 515 and pour out of the container when the container and
pourback spout 500 are tipped. The container and pourback spout 500
can be tipped in the direction that the pour tip is at its greatest
extension from the spout. For example, if the pour tip does not
extend all the way around the opening 515, the pourback spout 500
can be tipped in the direction of the pour tip. Alternatively, the
pourback spout 500 can be tipped in any direction.
[0097] The second protrusion 510 can be a rim. The rim can surround
the pour tip. After the liquid has been poured out of the container
via the pour tip, the pourback spout 500 can be returned to a more
upright orientation. The rim can capture at least some of the
liquid that can run down the pour tip. The rim can be configured to
reduce, minimize, or eliminate the liquid that can run down the
outside of the container. The gap between the pour tip and rim can
be of sufficient dimensions to capture the liquid and prevent it
from flowing over the second protrusion 510. In an embodiment, the
pour tip extends partially around the opening 515 so that the
liquid captured by the rim can flow into the opening 530.
[0098] In alternate embodiments, additional protrusions can be
provided concentrically, substantially concentrically, or not
concentrically around the first and second protrusions 505 and 510.
Additional protrusions can capture possible overflow of liquid.
[0099] FIGS. 7A and 7B illustrate a drainback (also "drain back"
herein) spout 600, in accordance with an embodiment of the
invention. FIG. 7A provides a side view of the drainback spout 600,
the drainback spout 600 having a cap 610. The drainback spout 600
can have an inner pour tip 615 surrounded by an outer skirt 620.
The cap 610 may be fitted over the outer skirt 620. FIG. 7B
provides another side view of the drainback spout 600. The outer
skirt 620 of the drainback spout 600 may be connected to an upper
ridge of a fitment. A lower ridge may extend below the upper ridge.
The upper ridge and lower ridge may be part of a fitment.
[0100] In an embodiment, the drainback spout 600 may have an inner
pour tip 615 surrounded by an outer skirt 620. The inner pour tip
615 and outer skirt 620 may surround an opening 625 in the spout.
An annular channel 630 may be provided around the inner pour tip
615 and within the outer skirt 620. The annular channel 630 may be
positioned between the inner pour tip 615 and the outer skirt
620.
[0101] In some embodiments, the inner pour tip 615 may surround the
opening 625 at least partway. The inner pour tip 615 may be curved
and contoured to follow at least part of the shape of the opening
625. In some embodiments, the opening 625 may have a circular
shape. The inner pour tip 615 may follow the circular shape. In
some embodiments, the inner pour tip 615 does not extend all the
way around the opening 625 so that the opening 625 may connect with
the annular channel 630. In some embodiments, at least part of the
bottom of the annular channel 630 may be level with or slant into
the opening 625. In some embodiments, a dip or funnel may be
provided that may slant downwards into the opening 625. In some
embodiments, a back opening may be provided so that the annular
channel 630 does not completely go around, but connects to the
opening 625 at the back.
[0102] The outer skirt 620 may surround the opening 625. In some
embodiments, the outer skirt 620 completely surrounds the inner
pour tip 615 and the opening 625. The highest portion of the inner
pour tip 615 may extend beyond the highest portion of the outer
skirt 620. The outer skirt 620 may have a circular cross-sectional
shape. Optionally, the outer skirt 620, inner pour tip 615, and
opening 625 may be concentric. In some embodiments, the outer skirt
620 and inner pour tip 615 may be substantially parallel to one
another.
[0103] The outside skirt may have an outer surface and an inner
surface. The inner surface may be the surface facing the inner pour
tip 615 and the opening 625 of the drainback spout 600. The
opposing outer surface may face away from the inner pour tip 615
and opening 625. In some embodiments, the outer skirt 620 can have
threads on outer surface. As shown in FIG. 7A, the threads on the
outer skirt 620 may also enable a cap 610 to screw onto the outer
skirt 620. In an embodiment, the cap is a measuring cap, enabling a
user to measure a predetermined volume of liquid (e.g., detergent).
In other embodiments, threads may be provided on the inner surface
of the outer skirt 620. A cap 610 may optionally screw into the
inner surface of the outer skirt 620. In some embodiments, the
bottom of the cap 610 may fit into part of the annular channel 630
between the inner pour tip 615 and the outer skirt 620. In some
embodiments, both the inner and outer surfaces of the outer skirt
620 may be threaded. In other embodiments, the outer surface of the
outer skirt 620, the inner surface of the outer skirt 620, or both
may have additional protrusions ridges, bumps, notches, clips,
teeth, holes, or other features that may enable a cap 610 to fit on
the drainback spout 600 and lock into or snap into place.
[0104] In some embodiments, the cap 610 may be formed of a
transparent material. Alternatively the cap 610 may be formed of a
translucent or opaque material. In an embodiment, the cap 610 may
be formed of the same material as the drainback spout 600. In
another embodiment, the cap 610 may be formed as the same material
as a liquid holding bag in fluid communication with the drainback
spout 600 (see above). The cap 610 may be formed from a polymeric
material. The cap 610 may be in the same recycling group as the
drainback spout 600 or the inner liner. In other embodiments, the
cap 610 may be formed from a pulp-molded material. In some
embodiments, the cap 610 may be formed from the same material as
the shell.
[0105] In some embodiments, the cap 610 may have a substantially
cylindrical sidewall. In some embodiments, the entire cylindrical
sidewall may fit over the outer skirt 620 and encompass the inner
pour tip 615. In some embodiments, the cap 610 may include an inner
cylindrical sidewall, a shoulder and an outer cylindrical sidewall
that may fit over the outer skirt 620. In some embodiments, the
inner cylindrical sidewall may be provided to fit over the inner
pour tip 615. Alternatively the cap 610 may be shaped to fit over
the inner pour tip and between the outer skirt and the inner pour
tip.
[0106] The annular channel 630 may be provided between the inner
pour tip 615 and the outer skirt 620. FIG. 6B provides a top view
of the annular channel (opening or gap 530, as illustrated). In
some embodiments, the annular channel 630 or dip that may connect
the annular channel 630 with the opening 625. A liquid may be
poured from the drainback spout 600 using the inner pour tip 615.
In some embodiments, after a liquid has been poured from the
drainback spout 600, liquid may drain back into the opening 625 or
be captured in the annular channel 630, at which point liquid can
drain into the opening 625. The annular channel 630 may direct the
liquid back into the opening 625 or other passages that may lead to
the interior of the container, such as a liquid holding bag in
fluid communication with the opening 625.
[0107] FIG. 8A shows a top angled view of a drain back pour spout
700, in accordance with an embodiment of the invention. The drain
back pour spout 700 may have an opening 705 in fluid communication
with a liquid holding bag (now shown; see above). The drain back
pour spout 700 may have an inner lip 710 and an outer sidewall 715
that surround the opening 705. A capture conduit 720 can surround
the inner lip 710 and may be surrounded by the outer sidewall 715.
A drainage passage 725 may be provided in the capture conduit 720.
In some cases, the capture conduit 720 is a trough. FIG. 8B
provides a lower angled view of a drain back pour spout 700. The
drainage passage 725 may provide a fluidic connection between the
capture conduit 700 and the interior of the container, such as a
liquid holding bat (see above).
[0108] In some embodiments, the inner lip 710 may completely
surround the opening 705. A portion of the inner lip 710 may extend
higher than another portion of the inner lip 710. In some
embodiments, about three quarters, two thirds, or one half of the
inner lip 710 may extend higher than the other portion of the inner
lip 710. In some embodiments, the taller portion of the inner lip
710 may extend taller than the outer sidewall 715 while the shorter
portion of the inner lip 710 does not. In some embodiments, the
transition between the taller and shorter portions of the inner lip
710 may contoured so that the exposed edges of the inner lip 710
are curved. The outer sidewall 715 may have the same or
approximately the same height all the way around.
[0109] With continued reference to FIGS. 8A and 8B, In an
embodiment, the capture conduit 720 may be provided between the
inner lip 710 and the outer sidewall 715. The capture conduit 720
may be provided lower than the inner lip 710 and the outer sidewall
715. The capture conduit 720 may be formed between the inner
surface of the outer sidewall 715 and the outer surface of the
inner lip 710. In some embodiments, the capture conduit 720 may
form a circular or elliptical shape around the inner lip 710. The
capture conduit 720 may include a floor that may connect the inner
lip 710 and outer sidewall 715. In some embodiments, the floor and
capture conduit 720 may form a ring-like shape. In some
embodiments, the floor may form an uninterrupted annular shape,
while in other embodiments, one or more drainage passageways may be
provided in the floor of the capture conduit 720.
[0110] In an embodiment, a drainage passage 725 may be provided in
the capture conduit 720. In some embodiments, only one drainage
passage 725 may be provided. Alternatively, a plurality of drainage
passages 725 (e.g., 2, 3, 4, 5, 6, or more) may be provided. The
drainage passages 725 may be holes, vents, openings 705, cracks,
tubes, or any other passageway that may fluidically connect the
capture conduit 720 and the interior of a container in fluid
communication with the drain back pour spout 700. The drainage
passage 725 may allow a liquid captured within the capture conduit
720 to drain into the container. In some embodiments, the drainage
passage 725 may direct the capture liquid into the opening 705.
Alternatively, the drainage passage 725 may separately drain the
liquid into the container. The drainage passage 725 may be provided
at the floor of the capture conduit 720. In some embodiments, the
drainage passage 725 may include part of the inner lip 710 or the
outer side wall.
[0111] In some embodiments, the drainage passage 725 may be located
in the capture conduit 720 on the side furthest from the tallest
portion of the inner lip 710. For example, the drainage passage 725
can be located at the side of the drain back pour spout 700 closer
to the shorter portion of the inner lip 710. Positioning the
drainage passage 725 away from the tallest portion of the inner lip
710 may prevent or reduce liquid from flowing out of the container
into the capture conduit 720 when the liquid is being poured out of
the container. After liquid has been poured from the container, and
container is returned to an upright position, some of the liquid
may be captured within the capture conduit 720, and may flow
through the drainage passage 725 into the interior of the
container.
[0112] With reference to FIGS. 9A and 9B, a drain-back pour spout
800 is shown having registration members 805. The registration
members 805 can be configured to mate with registration features on
a skeleton shell (see above). In some embodiments, the registration
members 805 can be for locking the drain-back pour spout 800 to a
skeleton shell, such as a neck region of the skeleton shell (also
"shell" herein). In an embodiment, the registration members 805 are
formed to complement an inner surface of the skeleton shell. In
another embodiment, the registration members 805 can be configured
to lock the spout 800 to prevent or minimize rotational movement,
vertical movement (i.e., movement along an axis orthogonal to a
base of a container having the spout 800), or horizontal movement
(i.e., movement along an axis parallel to a base of a container
having the spout 800). In an embodiment, the registration members
are configured to reduce or eliminate the rotation of the
drain-back pour spout 800 when it has been enclosed by a skeleton
shell, such rotation coming by way of a user rotating a cap of the
drain-back pour spout 800, for example. In an embodiment, the
drain-back pour spout 800 can include 1, or 2, or 3, or 4, or 5, or
6, or 7, or 8, or 9, or 10 registration members. The registration
members 805 can have any shape, size and configuration. The
registration members 805, as illustrated, have an elongate,
rectangular shape, with a horizontal cross-beam. In an embodiment,
the registration members 805 can be formed of ridges. In another
embodiment, the registration members 805 can be formed of notches
(e.g., metallic notches, polymer notches). In another embodiment,
the registration members 805 can be formed of grooves. In another
embodiment, the registration members 805 can be formed of one or
more of notches, ridges and grooves. In another embodiment, the
registration members 805 can be formed of a magnetic material or a
locking mechanism. In another embodiment, the registration members
805 can be formed of one or more hook-and-loop fasteners. In
another embodiment, the registration members 805 can include one or
more metal hooks.
[0113] In an embodiment, the registration members 805 can be
circular or have circular cross sections. In another embodiment,
the registration members 805 can be triangular. In another
embodiment, the registration members 805 can be box-like. In
another embodiment, the registration members 805 can be
rectangular. In another embodiment, the registration members 805
can be pentagonal. In another embodiment, the registration members
805 can be hexagonal. In another embodiment, the registration
members 805 can be heptagonal. In another embodiment, the
registration members 805 can be octagonal. In another embodiment,
the registration members 805 can be formed of 1, or 2, or 3, or 4,
or 5, or 6, or 7, or 8, or 9, or 10 cross beams. In another
embodiment, the registration members 805 can be "H" shaped (as
illustrated).
[0114] In another aspect of the invention, a method for assembling
a liquid holding container is provided, the method comprising
enclosing a liquid holding bag in a low embodied energy skeleton
shell, the liquid holding bag comprising a drain-back pour spout.
In an embodiment, the liquid holding bag can have a thickness
between about 0.001 inches and 0.025 inches. In another embodiment,
the drain-back pour spout is disposed at a top portion of the
liquid holding bag.
[0115] In an embodiment, containers are able to me made on
high-speed production lines and high speed filling line in order
reduce costs and be competitive with other aforementioned packaging
technologies. In some embodiments, containers or bottles can be
fully assembled prior to filling. The pouches could be made on a
horizontal forming machine with or without fitment inserter. The
pouches could be made on other known machines. They are then
assembled into the skeleton shell. Either the pouch or the shell,
or both could have one or more features to facilitate automated
assembly. The skeleton shell and pouch with fitment are then
assembled. A standard bottling line can be used where the container
fills similarly to a standard bottle. In such a case, various
components provided herein, such as skeletons and liquid holding
bags, can be integrated into existing standard bottling lines,
thereby making use of exiting infrastructures. In other
embodiments, the pouch and fitment can run and be filled on either
Horizontal Form Fill machines or Vertical Form Fill machines. These
filled pouches can then be assembled to skeleton shells to complete
the product containers.
[0116] Containers provided herein can be designed to minimize
materials cost, thus aiding in the reduction of post-use waste. In
addition, materials can be selected so as to minimize environmental
impact. For example, the skeleton can be formed of a biodegradable
material.
[0117] In some embodiments, containers can be permanent containers.
In some embodiments, containers can be designed to mate various
components, such as caps and pouches. In some cases, containers can
be designed to mate with smart caps and pouches. In various
embodiments, containers can be configured for use with turn-key
integrated manufacturing equipment.
Filling Containers
[0118] In various embodiments, methods for filling containers
having liquid holding bags within skeleton shells are provided. In
an embodiment, containers are filled with a detergent. In an
embodiment, there is space between a skeleton and a liquid holding
bag within the skeleton so that air (or another gas) within the
skeleton (or shell) can be displaced through the shell as the
liquid holding bag is filled. In addition, air can pass through the
skeleton to fill the volume as contents are dispensed from the bag.
Allowing air to pass into the volume inside the skeleton as the
contents are dispensed from the liquid holding bag helps with the
smooth dispensing of the contents of the liquid holding bag. In an
embodiment, the flow of air through the skeleton can be achieved
using the porosity of the skeleton. In another embodiment, the flow
of air through the skeleton can be achieved with the aid of a vent
in the skeleton. In such a case, the vent can be provided at a
position where there is little risk of puncturing the liquid
holding bag.
[0119] In an embodiment, a container, such as the container 200 of
FIG. 3C, can be filled by introducing content, such as liquid
content, through a closure of the container and into a liquid
holding bag of the container. The closure can be a sealable or
re-sealable closure. In an embodiment, as the liquid holding tank
is filled with the contents of the container, gas, such as air, is
displaced.
[0120] In an embodiment, before filling, the liquid holding bag
within the skeleton can be rolled to assist with the laying of the
liquid holding bag within the skeleton. In this case, the liquid
holding bag can be folded or rolled in such a way that it can
easily unfold or unroll, such as, for example when the liquid
holding bag is filled. Any folds or rolls may be lightly held by
one or more holding members, such as, e.g., thin pieces of tape
that will release as the bag fills. Alternatively, the bag can be
held in the folded or rolled condition by an adhesive, clip or
band. During filling, as the body of the liquid holding bag
expands, such as, for example, by injecting a gas into the bag
prior to filling or expansion of the liquid holding bag upon
filling the bag with its contents, the retaining means can be
ruptured or removed from the liquid holding bag to allow the body
of the liquid holding bag to expand. By folding or rolling the
liquid holding bag prior to laying it into the skeleton of the
container, various issues, such as, for example, the liquid holding
bag getting caught by the skeleton when enclosing the liquid
holding bag, can be minimized. This filling procedure further helps
the liquid holding bag fill properly, as it will assume the correct
internal orientation when filled.
[0121] In an embodiment, the liquid holding bag has a volume
greater than the internal volume of the skeleton. In this way, when
the liquid holding bag of the container is filled, the liquid
holding bag will come in contact the inner surface of the skeleton.
This can help ensure that the weight of the contents is supported
by the skeleton rather than by the liquid holding bag.
[0122] In some cases, the closure of a liquid holding bag includes
the pour spout (e.g., drain-back pour spout) of the liquid holding
bag.
[0123] In some embodiments, after filling, the openings through
which content is introduced to the liquid holdings, such as the
closures of the liquid holding bags, are sealed. In an embodiment,
the closures can be sealably or re-sealably closed with a sealing
member, such as a cap (e.g., smart cap), twist cap, snap cap, or
lid. The closures can be sealed in a controlled environment, such
as an inert environment or under vacuum, or in the ambient
environment.
[0124] In some embodiments, the openings through which content is
introduced to the liquid holding bags is sealed with the aid of a
removable sealing member having a gripping member for enabling a
user to remove the seal. In some cases, the opening of a closure is
sealed with a sealing member and further sealed with a cap. A user
removes the cap and removes the sealing member to expose the
opening of the closure.
[0125] A sealing member can be reversibly removable. That is, a
user can remove the sealing member to expose the opening of the
closure and replace the sealing member to reseal the opening.
[0126] FIGS. 10A-10D schematically illustrate a pour spout 1000
having a removable sealing member 1005, in accordance with an
embodiment of the invention. The pour spout 1000 can be mounted to
holding bags, fitments and shells provided herein. The pour spout
1000 can be a drain-back pour spout, configured to, for example,
capture spillover material from the container. The pour spout 1000
is configured for use with containers and liquid holding bags
provided herein. With reference to FIGS. 10A and 10B, the removable
sealing member 1005 includes a gripping member 1010 for enabling a
user to remove the removable sealing member 1005 from the pour
spout 1000. The gripping member 1010 is a tab (or projection), but
gripping members with other shapes, sizes and configurations are
possible. With reference to FIG. 10C, the removable sealing member
1005 includes an arrow 1015 for instructing a user as to the
direction to pull the gripping member 1010. For example, to remove
the removable sealing member 1005, the user can grip the gripping
member 1010 and force it (e.g., push or pull) in the direction of
the arrow 1015. With reference to FIG. 10D, the pour spout 1000
includes a capture conduit 1020 to capture content from a container
in fluid communication with the pour spout 1000. In some cases, the
capture conduit 1020 is a trough that captures excess content
(e.g., spillover).
[0127] With reference to FIGS. 11A-11D, the removable sealing
member 1005 can be removed from the pour spout 1000 to expose an
opening 1025 (see FIGS. 11C and 11D) of the pour spout 1000. The
opening 1025 can permit a user to dispense the content of a
container having the pour spout 1000. The pour spout 1000 includes
a drainage passage 1030 (see FIG. 11A) that is in fluid
communication with a liquid holding bag of a container (not shown)
having the pour spout 1000.
[0128] The opening 1025 can have various shapes and sizes. In some
embodiments, the opening 1025 has a cross-section that is in whole
or in part circular, triangular, square, rectangular, pentagonal,
hexagonal, heptagonal, or octagonal.
[0129] The opening 1025 is defined by a wall having a rim 1025a.
The pour spout 1000 includes a side opening 1035 extending from the
rim 1025a to a base of the capture conduit 1020. The side opening
1035 terminates at the drainage passage 1030. The opening 1025 and
the side opening 1035 are sealed with the removable sealing member
1005. Removal of the removable sealing member 1005 exposes the
opening 1025 and the side opening 1035. In another embodiment, the
sealing member 1005 is only partially removed, which can be
sufficient to allow the contents of the container to be dispensed
while still remaining partially joined to the spout 1000. The
sealing member 1005 can then be used to re-seal the container. In
some cases it can be returned to its original position for
re-use.
[0130] In some embodiments, the side opening 1035 of the pour spout
1000 can be precluded and the pour spout 1000 can include only the
opening 1025. The pour spout 1000 can include the drainage passage
1030 for directing material to a liquid holding bag in fluid
communication with the spout 1000. The removable sealing member
1005 in such a case can be shaped to cover the opening 1025. For
example, the opening 1025 can be circular and the removable sealing
member 1005 can be circular. A user can remove the removable
sealing member 1005 by pulling on the tab 1010.
[0131] In some embodiments, the removable sealing member 1005 is
disposable. The removable sealing member 1005 can be formed of a
recyclable and/or biodegradable material, such as a polymeric
material or vegetable material.
[0132] In an example, a container is provided having the pour spout
1000. A user removes the removable sealing member 1005 by pulling
on the gripping member 1010 to expose an opening of the pour spout
1000. The user inverts the container to remove a certain quantity
of material in the container, and subsequently turns the container
upright. Some of the material from the container spills into the
capture conduit 1020 and is subsequently returned to the container
via the drainage passage 1030.
[0133] The removable sealing member 1005 can provide various uses.
In some situations, the removable sealing member 1005 can enable
vertical (e.g., a container aligned with the gravitational
acceleration vector) filling and sealing of a container having a
spout with the removable sealing member 1005. In an example, a
container is filled vertically and subsequently sealed with the
removable sealing member. In some cases, the container can be
molded closed. This can aid in minimizing, if not preventing,
leaking during container filling and sealing.
[0134] In an example, a spout, such as the spout 1000, can be
attached to a pouch (or material holding vessel). The spout can be
sealed to the pouch. The pouch can then be filled in a vertical
fashion. In some cases an opening of the spout can be sealed with
the aid of a sealing member, such as the sealing member 1005. The
pouch may be vacuum sealed, or sealed in an inert (or other
controlled) environment. The spout can then be enclosed within a
cap. In some situations, the sealing member can be precluded and
the spout can be sealed with the aid of the cap.
[0135] Containers can benefit from certain features to help their
merchandizing. These could include an ability to suspend the
product at point of sale. This could include features to allow for
the suspension on rails of the recharge pouches. Recharge pouches,
or refill pouches, could be sold as single items or as groups of
pouches, and are swappable into a skeleton shell after another one
has been emptied. For example, a single pouch can be purchased and
inserted into the skeleton shell of another container after the
removal of the skeleton shell of that container. A number of
pouches could be sold with a single skeleton shell. The skeleton
shell could be intended to be recycled after a number of uses or
intended to be used indefinitely. The recharge pouches could have a
limited amount of packaging attached at retail points for branding
purposes or merchandizing purposes. This limited packing could also
serve a function in the reconnection to the skeleton shell, its
subsequent use, or intended for removal and recycling. This new
packaging invention could have features for merchandizing or
meeting logistical needs.
[0136] For other contents that may not be dependent on fitments, a
flexible pouch mated to a biomaterial based thermoformed skeleton,
with the option of using recycled content in the format of a
bowl/cup/tray, could be used. Separable components for recycling
can be used in certain cases. There would be a removable tamper
evident seal. The liner would be separable from the bowl/cup/tray.
This could be for refrigerated or frozen items, such as, e.g.,
yogurt, ice cream, ready-to eat-meals, salads, dried fruit, olives,
and margarine. Such containers can be used with non-refrigerated
items (e.g., nuts, spices), and they could be resealable with the
aid of, e.g., lids or re-stackable peel away tabs. In an
embodiment, such containers can include a separable liner and
skeleton technology for items that are in jars or cans (structured)
or in stand up pouches. Items that could benefit from such
containers include items that could benefit from more structure but
less plastic, such as, e.g., nuts, dried fruits, and snacks.
[0137] While in various embodiments containers have been described
as being configured for storing and dispensing liquids, it will be
appreciated that containers of provided herein can be for storing
and dispensing non-liquids, gels, gel-like materials, solids, such
as edible or inedible solids, including powders.
[0138] Containers provided herein can be joined at one or more base
members. In an example, a container can include a skeleton shell
having a tri-fold design (i.e., opposing side members joined at a
base member).
[0139] One or more components, parts, features, or characteristics
of liquid containers, liquid holding bags and/or spouts known in
the art can be used with or incorporated into containers, holding
bags and/or spouts provided herein. See, e.g., U.S. Pat. No.
