Description
[0001] This invention relates to so-called Bag-In-Box (BIB) carton
packaging suitable for diverse flowable materials, such as liquids,
gels, granules, pellets, capsules, sachets, chunks, crystals,
flakes or powders.
[0002] Terminology--BIB
[0003] The term BIB is used herein for convenience to embrace
packaging with inner and outer structures of different materials. A
prime category features a relatively soft deformable inner liner or
bag and a relatively stiff, hard outer box or carton. The inner
structure is impermeable and sealable for contents
enclosure--whilst the outer structure need not be, but rather
serves as a protective outer cover.
[0004] Fundamentally, inner and outer structures are made
separately and independently by different processes and brought
together for contents fill. This contrasts with, say, continuous
sealed tube carton technology, such as represented by
TETRAPAK.TM.
[0005] Particular BIB concerns are carton case assembly erection,
bag (liner) insertion, inflation and fill. BIB offers the prospect
of collapse format, both before and after use, with attendant
savings in so-called in-bound logistics and post-usage
disposal.
[0006] Thus BIB obviates shipment and storage of empty containers
preparatory to contents fill. However, BIB does require mechanised
assembly preparatory to fill, and thus additional facilities and
operations at or prefacing a fill station. These counter savings in
transport and storage of empty rigid wall containers. Moreover, BIB
fill requires specialised equipment, generally incompatible with
that for rigid containers.
[0007] Regulatory & Environmental
[0008] Regulatory and environmental pressures militate against
rigid wall plastic containers, but both bag plastics and card are
biodegradable. Moreover, some territories apply import levies upon
weight of plastics material introduced, so minimal plastic bag mass
is advantageous. Both carton and bag lend themselves to production
from materials which can be recycled.
[0009] Bag
[0010] Although commonly, thin walled for economy of
production--and so vulnerable, to puncture, tear or rupture--a bag
lends itself to collapse before and after use for contents storage.
The Applicant has used this to advantage in bag installation.
[0011] Carton or Box
[0012] A relatively stout outer box or carton offers protection and
support to an otherwise vulnerable bag. Mutual bag-carton
interaction--and in particular relative location--pose particular
challenges for BIB packaging.
[0013] Regulatory & Environmental

[0017] Prior Art--Conventional BIB
[0018] In a conventional carton assembly and erection to an
open-ended sleeve format is undertaken separately from bag
(contents) fill. Bag fill is undertaken through a top neck or
spout, before installation of a (threaded) closure cap.
[0019] A filled bag is inserted through a carton open (top) end and
carton top flaps closed over the bag to create a full enclosure. A
bag neck and spout may be submerged within the closed
box--accessible by opening a panel or hatch. Alternatively, the bag
neck or spout penetrates a localised aperture in a box top
flap.
[0020] Mechanisation
[0021] In conventional mechanisation for mass production and
on-line fill, a case-erector is employed for carton assembly
erection and flap closure. For sealing a carton closed, hot melt
adhesive is applied to mutually overlaid panel faces and/or tape is
overlaid upon carton edges. However, adhesive and thin wall bags
are generally incompatible--and this has proved a deterrent quality
control concern in BIB adoption. Moreover, top entry bag insertion
dictates an open top carton configuration with closure panels or
flaps--requiring a discrete taping security step for retention.
[0022] Applicant's Earlier Technology
[0023] The Applicant has BIB technology with various (branded)
improvements, including . . .
[0024] JERRIBOX(.TM.)
[0025] The Applicant has devised a bespoke BIB container--branded
JERRIBOX(.TM.)--in which a special locating collar is fitted
between inner bag liner and outer box carton, to allow fill on a
fill line originally intended for rigid wall containers such as
plastics jerrycans.
[0026] The Applicant has also devised a collapsible flat pack
pre-assembled format, in which a collapse folded bag is sandwiched
within a collapse folded carton wrap--but for a protruding
neck--itself held captive by a locating and entrainment collar.
[0027] The Applicant has further devised pneumatic bag
inflation--branded PULSE PA(C)K(.TM.)--to effect, or at least
assist, bag and wrapped carton erection into a 3-D form,
preparatory to fill. A continuous or discontinuous (time/amplitude)
`controlled` individual pneumatic pulse or pulse stream is
envisaged for this.
[0028] Challenges arises in assembly, erection and contents fill of
such JERRIBOX(.TM.) containers. Thus conventional carton case
erectors cannot handle collapsed JERRIBOX(.TM.) containers without
some modification. The Applicant has devised re-configured case
erectors and a bespoke machine dedicated to bag erection and fill
from a collapsed form within a collapsed carton.
[0029] For use on a fill line, in particular with diving or
plunging head fillers, a protruding bag spout must be prevented
from retreating into an outer carton by bag deformation and
collapse. The Applicant's collar between bag neck and carton
aperture captures and inhibits bag neck axial movement in relation
to the carton.
[0030] Bag Orientation
[0031] Bag angular orientation or indexing within the carton is
also a factor, particularly for rectangular bags. With a bag collar
intervention between bag neck and carton, bag disposition reflects
relative locations of bag and collar, along with collar and carton.
Complementary inter-fitting, say rectangular, collar and carton
aperture profiles inhibit relative collar and carton rotation. For
bag neck screw closure fitment and tightening bag anti-rotation or
anti-torque provision is desirable.
STATEMENT OF INVENTION
[0032] According to one aspect of the invention
[0033] a BIB carton comprises
[0034] a bag location and retention cartridge or capsule,
[0035] configured as a compact module,
[0036] mounted upon or entrained with a bag neck
[0037] for insertion from outside the carton,
[0038] into a (pre-formed) carton panel aperture.
[0039] Alignment & Anti-Torque
[0040] An optional feature is complementary inter-fitting collar
and neck profiles. An example would be a serrated collar aperture
and radial protrusions on a bag neck. These are conveniently
disposed adjacent a bag neck ring which interacts with the
circumference of a collar aperture, or an upstand rim
there-from.
[0041] The module is self-contained and pre-fabricated--with bag
ready for mounting and deployment. The cartridge can feature a bag
location and retention collar such as previously devised by the
Applicant, but adapted to facilitate bag installation--specifically
by admitting bag (collapse) pre-fold.
[0042] It is easier to handle and insert a pre-collapsed bag into a
carton than an erect one, with less risk of bag snagging, tear or
perforation. Thus, such a cartridge represents an alternative to
interleaving of flat bag and carton before erection--a technique
also conceived and pioneered by the Applicant.
[0043] External Installation
[0044] A cartridge can be installed from externally of a carton--a
radical departure from BIB convention. Indeed, the carton can be
fully erected and sealed into a closed 3-D form, merely leaving
exposed a modest profiled aperture for cartridge insertion. Thus
carton completion need not be delayed pending bag installation.
[0045] Carton Profile
[0046] The carton aperture desirably has flat sides to contact
corresponding flat sides on a bag collar. A rectangular aperture
and collar bounding profile are convenient, but other flat-sided,
polygonal forms could be used.
[0047] Complementary curvilinear forms might also be contrived,
given consideration to geometry for mutual interfit, retention,
location and anti-rotation.
[0048] Pre-formed Carton Aperture
[0049] A carton aperture to receive a cartridge--or rather its
location and retention collar--is desirably pre-formed. Thus an
aperture could be die cut as part of an elongate laid-flat strip
2-D carton blank, preparatory to folding over into a closed loop
3-D form.
[0050] Pre-Perforation of Carton Aperture Delineation
[0051] As an alternative to pre-cut out, a micro-perforated
aperture delineation might be pre-imprinted as a weakening line
into a carton panel. This preparatory local wall thickness
reduction and weakening facilitate punch through displacement to
reveal an aperture, upon cartridge forced insertion. One location
is desirably at an edge between top flap and side wall--so as not
to undermine stiffness--by contriving aperture bounding edges in
orthogonal panel faces.
[0052] Push Fit Cartridge Insertion
[0053] Unusually for BIB, cartridge insertion can be undertaken for
an assembled and closed carton, by push-fit and snap-action edge
rim retention lugs.
[0054] Frangible Collapsed Bag Tie
[0055] A cartridge features a collapse (say concertina) folded bag
disposed within a frangible or burstable enclosure, wrap or bag (of
say thin paper), with optional bounding closure tie, and a location
and retention collar entrained to a back neck.
[0056] Bag Within Collar Confines
[0057] A collapsed bag can sit within the bounding confines or
footprint of a peripheral rim upstand of a cartridge collar, or as
a snug cluster under a collar tray. The collapsed bag should be
unencumbered by its temporary enclosure, to remain freely
deployable--say, upon contents fill, with optional preparatory
pre-inflation (air) pulse burst. A compact pre-assembled cartridge
protects the bag until deployed within a carton and is more readily
shipped, stored and handled--so better suited to automated
mechanised assembly lines.
[0058] Cartridge Packing
[0059] Pre-assembled cartridges could be stacked upright in a grid
array in a carton tray, readily accessible for pick-and-place
collection by a robotic arm. A plunger nose penetrating the collar,
or rather the bag neck aperture, could be used, or a modest
suction, to grip a selected cartridge for withdrawal from its
shipment packaging tray. A standard case erector could be adapted
for full carton assembly, erection, end flap closure, bounding edge
tape seal and/or panel bonding--preparatory to mechanised cartridge
insertion by, say, a robotic pick-and-place arm.
[0060] Anti-Torque Bracing
[0061] A bag neck or spout must be braced against screw closure cap
fitment and tightening to seal--otherwise the neck, and with it the
bag, would twist and deform. This requires interaction between bag
and box. The cartridge, or rather the collar part of the cartridge,
has a reception aperture for bag neck insertion.
[0062] The collar aperture edge rim can be profiled as a slightly
raised, resiliently deformable snap-action interfit with a threaded
bag neck. Coarse circumferential segmentation or serration of such
a collar aperture upstand rim and co-operative interaction or
interfit with a complementary ribbed profile or at least radial
lugs upon a bag neck collar.
[0063] Interfit of collar aperture recesses and bag neck ribs or
lugs provides anti-rotational action and the interfit of a
rectangular profile collar bounding edge with a rectangular carton
aperture braces collar to carton. So overall, bag neck rotation
upon threaded closure cap screw tightening is inhibited. The collar
aperture upstand and bag neck collar abutment also inhibits bag
neck retraction under downward load of, say, a plunging head
filler.
[0064] Bag-Collar Entrainment vs Integration
[0065] Bag neck and collar can be mutually entrained discrete
elements (with say snap action interfit of profiled collar aperture
and bag neck) or integrated (say with a unitary moulding) upon bag
production. Entrainment favours pre-assembly of a collar and
collapsed back in a compact cartridge forma. Additional features
could be integrated with the collar--say for carton retention and
handling.
[0066] Integrated Clip
[0067] The collar desirably has an integrated retention `clip`
profile for interaction with carton panel edges. Clip action allows
for spring action by resilient deformation of collar wall and/or
carton panel edge.
[0068] Unitary Cartridge Module
[0069] The cartridge as a unitary module can thus clip--say with
positive snap-action--into a carton wall aperture.
[0070] Recessed Tray Profile
[0071] The recessed tray profile with inset bag neck or spout of
the Applicant's PCT/GB2004/002609 could be adopted. The tray serves
for spillage containment and local carton wall protection. In that
PCT case, options for integration of bag neck and collar and bag
installation from outside a carton were envisaged.
[0072] The present invention provides improvements in modular wrap,
location and retention. A tray collar preserves an overall
rectangular carton profile with bag in situ and a spillage
containment shield helpful as a splash guard in original contents
fill and subsequent user pouring--card carton material being
vulnerable to moisture wetting.
[0073] Collapse-Fold Bag+Collar
[0074] Pre-Wrapped Bag Cartridge
[0075] In a particular construction, a bag, pre-collapsed within
frangible (paper) outer shroud, has a neck entrained or integrated
with a locating collar. This pre-assembly is ready for installation
as a unitary module into an aperture in a carton wall, such as a
top closure flap and/or side panel.
[0076] Pre-Insertion
[0077] Such a bespoke collapsed bag and entrained locating collar
can be pre-inserted--ie before bag inflation and contents fill.
`Whole body` insertion in a larger than conventional BIB carton
(bag neck) aperture is envisaged. In some variants, (cartridge)
insertion could be combined with a carton closure step--by
co-operative interfit between collar and carton flaps.
[0078] Initial carton erection and closing could leave (part or
fully) open top flaps for interaction with the collar, before flap
closure and sealing. A so-called crash-lock top and bottom carton
end flap configuration could be contemplated. This would admit of
manual or simple mechanised operation--say with pre-glued panels
for bonding on mutual flap (closure and overlay) contact.
[0079] Closure--Lock
[0080] The collar could itself form a carton (top flap capture)
closure or lock. Such a closure might supplement, or even
substitute for, conventional carton flap closure techniques such as
tape or adhesive bonding.
[0081] Carton Re-configuration
[0082] The carton configuration admits of re-design over
conventional end flap closures.
[0083] Collar--Carton Interfit
[0084] Thus, collar and split flap interaction could be substituted
by collar and carton wall aperture interfit. Insertion action would
reflect collar interfit--with, say, selective use of deflection,
slide and/or rotation.
[0085] One-way Insertion
[0086] A one-way insertion mode would be desirable to inhibit
inadvertent unseating and withdrawal under transit vibration,
handling and bag inflation forces. Vigorous mix shaking as in paint
industry use would be and example. An irreversible insertion
without visible evidence of interference could serve as a tamper
evident closure.
[0087] Manufacture--Moulding
[0088] As to collar manufacture, whilst low cost (tooling) vacuum
forming techniques might be employed. For more elaborate forms,
such as integrated clip, injection moulding is envisaged. Further
features might then be incorporated in a common mould tool, without
disproportionate cost. For longer runs, injection moulding would
allow more elaborate feature integration--such as of collar and bag
neck.
[0089] Recycling
[0090] Ready reversal of installation and/or break out and
isolation of component elements upon BIB container discard after
use lends itself to re-cycling. Thus a collar moulding and bag
could qualify in the same plastics recycling category and are
readily separated from the carton itself in another category.
[0091] Collar (Clip) Retention
[0092] The collar desirably features retention clips for
interaction with carton panels or panel edges.
[0093] Discrete Clip
[0094] Discrete individual clips may be employed, say with a
one-way spring wedge or detent insertion action. A serrated
depending tang, spike or stud allows one-way insertion in a
complementary panel aperture, by temporary deflection of panel
edges--but inhibits removal by abutment with panel underside
faces.
[0095] Edge Clip Profile
[0096] Alternatively, a fragmented or continuous resiliently
deformable edge profile may be adopted. This profile is deflected
upon insertion just sufficiently to fit within a carton panel
mounting aperture, whereupon it springs back to inhibit withdrawal
by engaging panel inside faces. Continuity may run around the
entire clip periphery or segmented in juxtaposed runs along clip
side edges.
[0097] Flex Floor
[0098] For a collar configured as a shallow tray, with a peripheral
upstanding edge wall and top flange or lip overlay, a conical tray
floor profile admits flexing. Reversal of such flexing to stable
profiles on either side of an (unstable) flat plane in turn drives
the walls outward or inward--for panel aperture insertion or
location--retention.
[0099] Flexible Bag
[0100] Bag collapse pre-supposes a flexible bag (wall) --admitting
rolling and/or folding without permanent set or damage and
restitution of unfurled format.
[0101] Pillow Bag
[0102] A free-form so-called pillow bag--which is volumetrically
compatible with, and whose outer profile conforms to, the inner
profile of an outer carton containment--could be employed. That
said, rectangular format bags, with seams dictating a
pre-constrained outer profile, complementary with carton capacity,
could be used.
[0103] Roll/Fold Orientation
[0104] A bag roll or fold axis orientation transverse and/or about
the bag neck axis may be adopted. Bag orientation is facilitated by
correction collar positioning and retention by carton closure.
Alternatively, a concertina or successive mutual overlay, fold may
be employed. Multiple individual fold axes, in selective
combination across and/or along or parallel to a bag neck axis,
could cumulatively contrive a compact cartridge form. Yet such a
cartridge could be readily expandible--without snagging--in, say,
the manner of a parachute, to an unencumbered, fully-deployed form,
ready for contents fill.
[0105] Carton Configuration
[0106] An insertable from exterior bag-collar cartridge frees up
top closure constraints upon carton configuration. Thus split top
carton flaps could be replaced by a continuous wrap. Alternatively,
multiple top flap configuration could be adapted for collar
mounting--say to allow insertion in one plane, followed by
insertion in another plane. Reliance would then still be placed
upon a final taping of top and/or side flap seams to secure overall
carton closure. Bag inflation could be contrived to promote carton
(top flap) closure--ie a proportion of filled bag weight could be
transferred through neck locating collar, to the top flaps. The
collar itself could be configured to promote carton (top-side) flap
closure.
[0107] Collar Portion Interfit
[0108] Discrete complementary opposed collar portions could be
configured for co-operative locking interfit upon installation
around a protruding neck spout.
[0109] Collar Slot--Slide Action
[0110] A collar edge slot could allow (lateral) sliding insertion
of carton panel edges. Slot depth could allow either solid or
corrugated carton card materials. Slot walls could retain a modest
resilient spring action to grip inserted carton layers.
[0111] Split/Hinged Collar
[0112] A split and/or hinged collar configuration could facilitate
installation and promote carton closure.
[0113] Frangible Restraint Tie
[0114] A restraint tie, such as a tape, band or cord, could wrap
around a collapsed (rolled and/or folded) bag to preserve collapsed
condition until severed or fractured preparatory to, or upon bag
deployment. A `self-destruct` tie, or overall bag wrap or
sheath--ie one which failed (eg rupture or burst) upon intentional
bag inflation load--could help protect the collapsed bag cartridge
in the interim.
[0115] Sheath Format
[0116] A sleeve or collar sheath format would suit a cylindrical
bag roll about the bag neck axis. A pneumatic pulse inflation could
burst or rupture such restraint, without damage to the bag wall
itself.
[0117] Inflated Bag--Split Collar Interaction
[0118] Bag inflation could promote or secure split collar
installation by, say, bag top wall contact bias against a collar
underside, to resist collar fold or collapse. Thus, for example,
reversible cone collar floor action could be triggered by contact
with inflated bag top wall shoulders, in turn to flip collar walls
outward into secure location with carton top panel/flap edges.
[0119] Pre-tensioned Bag Wall
[0120] A bag wall pre-tensioned or biassed to impart an inherent
roll-up or collapse fold tendency or pre-disposition could be
contrived to keep a split collar ready for installation. That is,
bag collapse into a compact pack would accompany collar element
(re-)disposition.
[0121] Residual Contents Discharge
[0122] Once bag contents have been discharged, while the bag
remains within a carton, the bag cartridge could be removed and the
bag rolled and/or folded to promote residual contents discharge. A
bag with a permanent memory or set for reversion to a collapsed
form would impart contents discharge bias throughout its temporary
storage role. Such a set could be imparted by differential local
heat treatment and/or wall stretch or thickening upon initial bag
fabrication such as from a continuous tube, or as post-fabrication
treatment by applying a heated tool.
[0123] Flat Pack
[0124] Operationally, collapsed bag cartridges and collapsed
cartons could be delivered to a fill location. This eases so-called
`inbound logistics` and minimises local storage space requirements.
Bag cartridges suitable for a variety of carton shapes and sizes
also simplify stock requirements.
[0125] Carton Liner
[0126] A bag cartridge is compatible with a carton liner, inserted
upon initial carton erection, before end flap closure and before
bag cartridge installation.
[0127] Retained Collar
[0128] A retained collar keeps a bag cartridge in place under
disturbing vibrations in transit and supplements the effect of a
filled bag weight in pulling the bag down inside a carton. Thus a
combination of bag seat upon a carton base and hang from a collar
seated into a carton top keeps the bag deployed and collar in
place.
[0129] Bias Weight
[0130] A bias weight could be attached to a bag, say at a bottom
edge, to promote bag deployment. An example would be a slab of
dense material, or even the carton wall material in individual or
multiple layers. A weight profile complementary to the inner carton
wall profile would help bag and carton alignment. Rounded edge
forms could discourage snagging between weight and inner walls. The
weight could feature a cushion or pillow bag to absorb and dampen
impact shock upon the carton.
[0131] Air entrapped below the weight could act as a cushion damper
against the sudden impact shock of bag inflation or contents fill.
An expandible profile mass, such as a base slab with fold-up/down
peripheral walls, could be employed to fit within a carton inner
profile upon bag deployment. This would preserve bag and carton
mutual alignment and inhibit bag snagging.
[0132] Overall Costs
[0133] Overall a bag cartridge offers low fabrication and assembly
costs--competitive with conventional BIB structures and rigid
walled jerrycans.
[0134] Terminology--Cartridge--Capsule
[0135] The term collar is used herein to embrace either discrete
element or integrated with bag neck formats.

about a bag neck axis and temporary containment in an enclosure,
wrap, tie collar or sheath;
[0141] NB . . . A particular example would be a paper bag,
burstable upon a preparatory air pulse applied through the bag neck
for bag deployment.
[0142] FIGS. 2A and 2B show collar fitment of a bag cartridge of
FIGS. 1A-1C to an erect pre-assembled carton, through a pre-formed
carton aperture with which the collar is a snug interfit;
[0143] NB . . . Installation can be entirely from externally of a
fully assembled, erected, closed and sealed carton.
[0144] That said, sliding insertion from one free side edge of a
residual open top flap, pre-closure, remains an option--as
reflected in FIG. 10C.
[0145] FIGS. 3A through 3D show successive installation stages for
a collapsed bag cartridge of FIGS. 1A-1C, culminating in bag neck
or spout closure cap fitment and screw tightening (resisted or
braced against by in-built anti-torque provision);
[0146] FIGS. 4A through 4D show a bag cartridge with pre-collapse
folded bag upon a collar with integral multiple discrete
resiliently deformable (edge) retention clips;
[0147] NB . . . A tapered entry nose clip profile allows ready
one-way insertion, but an end abutment ledge inhibits inadvertent
dislodgement or removal.
[0148] FIGS. 5A through 5D show a bag cartridge collar with
alternative integral retention clips to FIGS. 4A-4C;
[0149] FIGS. 6A through 6D show a bag cartridge collar with
continuous peripheral clip side wall and edge profile;
[0150] FIGS. 7A through 7D show a bag cartridge collar with
multiple discrete depending retention spring clips integrated with
a peripheral rim flange;
[0151] FIGS. 8A through 8D show a bag cartridge collar rim
configured as a bag enclosure boundary wall;
[0152] NB . . . bag profile could be adapted (say, locally waisted)
to skirt around such a fence upon bag deployment, so the protective
shield thereby afforded for a collapse folded bag does not impede
or prejudicially deflect bag deployment.
[0153] FIGS. 9A through 9D show a bag cartridge with convoluted,
stacked multi-layered bag collapse fold for offset `directed`
deployment;
[0154] FIGS. 10A through 10C shows a bag cartridge with collar edge
slot (slide insert) interaction with a bespoke carton top flap and
wall configuration;
[0155] FIGS. 11A through 11G show a bag cartridge with collar edge
slot (slide insert) interaction with another bespoke carton top
flap configuration to FIGS. 10A-10C;
[0156] FIGS. 12A through 12F show a bag cartridge with collar
location and push-fit locking tab;
[0157] FIGS. 13A through 13C show a bag cartridge with deformable
(flex) wall collar retention;
[0158] FIGS. 14A through 14I show a cylindrical barrel
configuration bag cartridge with collapsed bag containment in a
drum collar with depending locking and spill tab;
[0159] FIGS. 15A through 15E show a barrel or drum bag cartridge
with reversible flip action recessed/pop-up collar for a captive
bag neck.
[0160] FIGS. 16A through 16D show a bucket or pail format carton
fitted with a compact shallow drum lid bag cartridge having a
wide-span contents access aperture;
[0161] FIGS. 17A through 17C show mechanised bag cartridge
installation, by an automated `pick-and-place` robotic arm, into a
carton top--side aperture, with umbilical feed of contents and/or
pneumatic inflation;
[0162] Anti-Torque Provision
[0163] FIGS. 18A through 18D show enlargement detail of
location-retention collar and bag neck co-operative anti-torque
(and anti-plunge) interaction for bag cartridge installation;
[0164] More specifically:
[0165] FIG. 18A shows a scrap front elevation of a collar with bag
neck insertion from below; a neck retention and thrust ring is
apparent, for interaction with a collar aperture rim upstand, more
apparent inf FIG. 18D;
[0166] FIG. 18B shows a scrap section, taken along the line B-B' in
FIG. 1C, of bag neck and collar of FIG. 18A installed in a carton
top recess;
[0167] NB . . . a carton wall instep is depicted for collar
support, but could be omitted in favour of a carton aperture
corresponding to the collar footprint--reliance then being place d
upon collar self-support span between aperture edges;
[0168] FIG. 1C shows a plan view of the installed collar and bag of
FIGS. 18A and 18B, showing collar aperture segmented profile;
[0169] FIG. 18D shows a local sectional enlargement of collar
retention by neck shoulder and anti-rotational complementary
interfit of neck and collar rim profiles;
[0170] Bag Pre-Insertion in Carton
[0171] FIGS. 19A through 20B reflect bag pre-installation within a
carton as a collapsed flat folded sandwich, prior to location and
retention collar fitment from the opposite side of a carton wall to
the intervening bag--and are included for completeness as an
alternative to bag pre-collapse fold within a cartridge format.
[0172] The intention is to depict the wider applicability of an
anti-torque feature between collar and bag neck--for both
pre-installed bag and collapsed bag cartridge formats.
[0173] It also follows that a bag, whether presented as an open
face or flat-pack, or pre-collapsed, could be introduced from
within a carton, or rather from an inside face of a residual open
top flat, with a retention collar presented afterwards.
[0174] Taken in the context of the foregoing provisos . . .
[0175] FIGS. 19A through 19C show successive stages of bag
insertion and collar fitment in relation to a collapsed flat pack
carton sleeve wrap;
[0176] More specifically:
[0177] FIG. 19A shows a collapsed flat--albeit not wrapped or
over-folded--bag liner without closure cap juxtaposed with a
collapsed carton sleeve wrap;
[0178] FIG. 19B shows a collapsed carton sleeve wrap;
[0179] FIG. 19C shows a local enlargement detail of FIG. 19B with
location and retention collar installed upon a bag neck protruding
through a carton wall aperture to mutually entrain carton and
bag;
[0180] FIGS. 20A and 20B show a fully assembled collapsed flat pack
carton with installed flattened--but not compact folded--bag;
[0181] The bag and carton interfit of FIGS. 19A through 20B can be
replaced by a pre-collapsed bag cartridge as reflected in preceding
FIGS. 1A through 17C and following FIGS. 21A onwards;
[0182] More specifically:
[0183] FIG. 20A shows threaded closure cap juxtaposition with a
protruding bag neck;
[0184] FIG. 20B shows closer cap rotary threaded installation and
tightening, with collar-bag neck and collar carton aperture
co-operative (anti-torque) inter-fit;
[0185] Reverting to the bag cartridge format, various cartridge and
carton configurations and relative dispositions are explored in
FIG. 21 et seq.
[0186] FIGS. 21A through 21E show assembly of a bag cartridge from
collar fitment to the neck of a collapse folded bag disposed within
an outer wrap with frangible tie, for installation into a carton
aperture;
[0187] More specifically . . .
[0188] FIG. 21A shows a cartridge of assembled collar and wrapped
collapse folded bag, with closure cap omitted for clarity to reveal
anti-torque interfitting abutment profiles on bag neck and collar
aperture;
[0189] FIG. 21B shows mutually aligned wrap folded bag and collar
juxtaposed for interfit--ie collar mounting upon bag;
[0190] FIG. 21C shows pre-assembled bag cartridge juxtaposition
with a carton aperture;
[0191] FIG. 21D shows cartridge installation upon a carton, with
closure cap fitted (albeit this would be undertaken finally after
contents fill);
[0192] FIG. 21E shows a variant collar aperture and bag neck
interfit profile, for unique indexed bag angular orientation;
[0193] Thus diametral slots in a bag collar aperture rim correspond
to diametral ribs on a bag neck;
[0194] FIGS. 22A through 22H reflect a bag fold and wrap sequence
for a bag cartridge of mutually entrained bag and (neck)
collar;
[0195] More specifically . . .
[0196] FIG. 22A depicts juxtaposed collar, frangible tie wrap
strip, and bag (neck);
[0197] NB the tie strip has an inherent weakness about the neck
aperture--and advantage is taken of this for strip rupture upon bag
inflation; a transverse diametral weakness to failure line is
depicted in broken line, and indeed could be expressed as strip
pre-perforation;
[0198] FIG. 22B shows an interfitted collar, bag neck and laid flat
bag;
[0199] FIG. 22C shows an initial longitudinal bag fold about a line
tangental to a bag neck;
[0200] FIG. 22D shows a subsequent reverse fold of underlying
folded bag panel about a line tangental to the bag neck, but on a
diametrally opposed side;
[0201] FIG. 22E shows a further longitudinal fold to create a strip
of width corresponding to the bag neck--or thereabouts;
[0202] FIG. 22F shows an initial transverse fold of the
longitudinal fold stack, and this is followed for further
over-folds to create the compact folded bag of stacked panels or
leafs of FIG. 22G;
[0203] FIG. 22G shows in fold of wrap strip to envelop the collapse
folded bag;
[0204] FIG. 22H shows joining, by edge overlap taping and/or
bonding, of the bag wrap;
[0205] FIGS. 23A through 23D show an alternative bag enclosure,
configured as a more solid card sleeve wrap, which also provides a
modest bag deployment bias and guidance mass upon wrap rupture and
bag release;
[0206] NB . . . Whilst a more robust card wrap strip could be
installed between bag and neck collar, as with FIG. 22A, mounting
upon the bag itself allows modest distributed bag wall loading;
[0207] More specifically . . .
[0208] FIG. 23A shows juxtaposed folded bag and under-tray of a
folded over card panel--mounted by an adhesive tape strip;
[0209] FIG. 23B shows opposed under tray panel ends wrapped around
the bag, and tucked under a bag neck rim;
[0210] FIG. 23C shows insertion of a completed bag cartridge in a
carton aperture;
[0211] FIG. 23D shows bag deployment upon release of the bias mass,
whose attachment to the bag underside promotes bag opening; in
doing so, the under tray expands by unfolding of a side panel, to
occupy the internal span of the carton and so help guide bag
movement;
[0212] FIGS. 24A and 24B show multiple bag cartridge installation
in a common carton or boundary;
[0213] NB . . . bag cartridges could be used for complementary
contents--as, say, a promotional retail item, also useful upon
consumption;
[0214] More specifically . . .
[0215] FIG. 24A shows dual bag cartridges disposed at opposite
sides of a carton;
[0216] FIG. 24B shows quadruple bag cartridges in a segmented
carton--or a cluster of nesting cartons of complementary form, in
this case a triangular foot print; these could be shrink-wrapped to
preserve the cluster until broken up for use;
[0217] NB . . . multiple carton contents could be depicted by
carton marking or delineation;
[0218] FIGS. 25A through 25E show variant dispositions of bag
cartridge in cartons of different shapes and sizes;
[0219] More specifically . . .
[0220] FIG. 25A shows a bag cartridge fitted at an edge with neck
orientated sideways, rather than end-on;
[0221] FIG. 25B shows the arrangement of FIG. 25A fitted to an
opposite carton end;
[0222] FIG. 25C shows a curved profile collar fitted to a tall thin
carton;
[0223] FIG. 25D shows a triangular profile collar fitted to a
longitudinal edge of a wide shallow chest style carton;
[0224] FIG. 25E shows a collar fitted to a top edge of a tall
slender carton format;
[0225] FIGS. 26A through 26D show variant multiple bag
installations within a common carton, with respective bag necks
sharing a common neck collar piece;
[0226] More specifically . . .
[0227] FIG. 26A shows a dual side-by-side bag disposition;
[0228] FIG. 26B shows a triple bag in a triangular disposition;
[0229] FIG. 26C shows a triple bag with side-by-side neck
disposition;
[0230] FIG. 26D shows dual discrete bags with respective bag
collars at opposite ends of a carton;
[0231] FIGS. 27A through 27C show diverse carton formats;
[0232] More specifically . . .
[0233] FIG. 27A shows a polygonal--in this case hexagonal--carton
footprint;
[0234] FIG. 27B shows a triangular carton footprint;
[0235] FIG. 27C shows a semi-circular carton footprint;
[0236] FIGS. 28A through 28D show drum, bucket or pail carton
variants, with wide mouth necks occupying the entirety of a carton
end wall;
[0237] More specifically . . .
[0238] FIG. 28A shows carton formation by wrapping a panel around
an end tray configured as a bag cartridge;
[0239] FIG. 28B shows an assembled carton of FIG. 28A fitted with a
local neck alternative to a removable end panel;
[0240] FIG. 28C shows a flip top lid alternative to FIG. 28B;
[0241] FIG. 28D shows a circular lid alternative to FIGS. 28B and
28 C for the wrapped bucket container of FIG. 28A;
[0242] FIGS. 29A through 29B depict variant cylindrical carton
formats--designated by the Applicant as `CARDBOARD BOTTLE`.TM.;
[0243] More specifically . . .
[0244] FIG. 29A shows an exploded view of a narrow cylindrical
carton with opposed end caps configured as bag cartridges, for a
double-ended format, with the option of dual alternative contents
fill;
[0245] FIG. 29B shows an assembled carton of FIG. 29A, with one end
closure revealed--the other could be a blanking cap for a single
content package;
[0246] FIG. 29C shows a drum carton variant with dual semi-circular
end caps configured as bag cartridges for respective discrete
individual contents bags disposed side by side;
[0247] Such an arrangement would allow complementary contents fill,
such as red and white wine (DUO VIN(0).TM. or DEUXVIN.TM.);
[0248] FIG. 29D shows an assembled drum of FIG. 29C;
[0249] FIGS. 30A and 30B show different depth drum cartons, such as
of FIGS. 29A through 29D, with a common bag cartridge, deployed to
matching depth;
[0250] More specifically . . .
[0251] FIG. 30A shows a translucent view of a drum carton with
internal bag concertina collapse folded to less than its full
capacity to suit a shallow drum depth;
[0252] FIG. 30B shows a deeper drum carton, such as of FIG. 30A,
with the bag extended to take advantage of the full drum depth;
[0253] Thus a given bag cartridge diameter and variable expansion
bag could suit a range of drum depths and attendant volumes--say, a
0.5, 1.0, 1.5 and 2.0 litre capacity for liquids from water or
milk, through juice, to wine;
[0254] FIGS. 31A through 31C depict a rolled sleeve carton drum
construction;
[0255] More specifically . . .
[0256] FIG. 31A shows a bag with oppose end fitments--one a neck
collar, the other a blanking cap--laid flat upon a card sheet,
preparatory to assembly;
[0257] FIG. 31B shows initial rolling of the bag and card wrap
about mutually aligned collar and end cap set upright therefrom in
a common rolling axis;
[0258] FIG. 31C shows an assembled tube with outer card wrap edges
tape sealed or bonded;
[0259] The initial flat format of bag and card allows compact
stacking in a cassette format ready for assembly;
[0260] FIGS. 32A through 32C depict a flip-top closure for a bag
cartridge;
[0261] More specifically . . .
[0262] FIG. 32A shows a side elevation of a self-sealing hinged lid
flap fitted to a neck collar
[0263] FIG. 32B shows a closed flip top lid recessed within a
shallow depth collar tray;
[0264] FIG. 33C shows the flip top lid of FIG. 33B open about a
minimal live hinge connection;
[0265] FIGS. 33A and 33B depict a ring-pull closure for a bag
cartridge;
[0266] More specifically . . .
[0267] FIG. 33A shows a sealed ring closure set into a collar
tray;
[0268] FIG. 33B shows a pulled open ring closure;
[0269] FIGS. 34A and 34B show a semi-circular flip lid, with wrap
around edge seal;
[0270] More specifically . . .
[0271] FIG. 34A shows the lid open;
[0272] FIG. 34B shows the lid closed;
[0273] FIGS. 35A and 35B depict an integrated collar and bag neck
configuration;
[0274] More specifically . . .
[0275] FIG. 35A shows an integrally moulded convoluted fold funnel
extension of an otherwise conventional bag neck;
[0276] FIG. 35B shows the funnel extension of FIG. 35A flipped over
to create a circumferential collar;
[0277] NB . . . Collar As Carton Wall
[0278] FIGS. 28A-D, 29A-C, 30A-B and 31A-C reflect a blurring of
distinction between bag cartridge and carton. Thus a cartridge, or
rather a collar, can serve as or substitute for a carton end wall.
This `liberates` the carton configuration from conventional flat
folded-over, tuck-in panel constructions--not least as interaction
of (collar) end caps and intervening carton wall can replace carton
end flaps, with associated tape edge seal and bonding. It follows
that the term carton used herein should be broadly interpreted to
include such transitional or merged forms which the present
invention admits.
[0279] Extended collar configurations could serve as carton side
walls--ie not merely end wall closures. An example could be any of
FIGS. 28 through 31, but particularly the `CARDBOARD BOTTLE`.TM. of
FIG. 29B. An example is included in FIG. 29B1
[0280] Referring to the drawings . . .
[0281] The drawings are presented in a diagrammatic illustrative
style, with simplification for ease of comprehension--it is
believed without laborious detailed description, beyond the general
principles outlined and taken with the component list.
[0282] An assembled JERRIBOX(.TM.) BIB container 10--reflected in
FIGS. 2B and 3D--features an outer carton 14 enshrouding an
internal bag liner 11, with a protruding neck or spout 13 entrained
by a location and retention collar 12.
[0283] Collar 12 serves to locate--and in the present invention
also retain--in an aperture in carton 14. Collar 12 thus represents
a `constructive intervention` between bag 11 and carton 12. As the
collar 12 is now united with a pre-collapse folded bag 11 in a
so-called bag cartridge 20 according the present invention, overall
a bag cartridge 20 interacts with a carton 12. Indeed, as will be
described later, a bag cartridge 20 can substitute for what would
otherwise be carton (side or end) wall.
[0284] Container 10 is assembled from pre-fabricated components or
sub-assemblies. A principal sub-assembly of the present invention
is a so-called bag cartridge, capsule or cassette module 20,
combining a compact collapse folded bag 11 within a collar 12.
Compact means that the bag 11 is collapsed to a format 21 within
the footprint, span or embrace of a collar 12. Bag 11, and
optionally part of collar 12, are within a protective temporary
outer enclosure or wrap, such as a paper strip 90 (omitted for
clarity in most Figures).
[0285] A principal assembly consideration is bag cartridge 20
installation by insertion from outside a pre-assembled carton 14.
Traditional BIB has located a pre-filled bag into an open top of a
partially pre-assembled carton. Earlier proposals have used a bag
and carton united--even pre-joined (bonded) before assembly. It is
envisaged that bag cartridge 20 could be produced off-site and
simplify container assembly.
[0286] Bag cartridge 20 features a rolled and/or folded up bag 21,
within a frangible strip wrap 90, or optionally secured by a
(temporary) frangible tie band 22. Diverse roll and/or fold bag
collapse modes are tenable--such as the transverse (to neck axis)
roll of FIGS. 1A-1C--but a prime fold sequence is elaborated in
FIGS. 22A-H.
[0287] FIG. 1D shows bag roll about a neck axis--with an outer
containment wrap, sheath or sleeve fitted. Other bag collapse
(fold) modes are explored later. Bag 11 thus remains in a compact
condition 21--readily handled and installed--until ready for
deployment--say by pre-inflation or contents fill, but only after
installation in a carton 14.
[0288] A thin-wall bag 11 is vulnerable to snagging, puncture or
tear, but when collapsed or gathered--say rolled or
(reverse/concertina) folded--to within compact format 21 presents a
more robust massed `bulk`. Thus a bag compact 21 is a robust
self-contained element, not dependent upon carton 14 for its
integrity. A seamless or freeform pillow bag 11 format could be
employed. This differentiates it from past bonded bag and carton
outer panels, such as GB959306.
[0289] Collar 12 could be a discrete element entrained with, or
captive upon, neck 13, say by a retention rim, shoulder washer or
circlip. Alternatively, an integrated neck 13 and collar 12--as a
unitary element (along with depending bag) could be contrived--say
as part of bag production. Integration frees up collar 12 and neck
13 design--to admit more diverse forms. FIGS. 35A-B depict a
formative example. Similarly, tie wrap 22 might be integrated with
collar 12 or neck 13--or indeed bag 11.
[0290] A band or strip tie 22 would spread wrap loads over the bag
11 wall, to obviate local constrictions or kinks. An overall sleeve
or collar would also serve. Alternatively, a draw cord running
through external bag wall loops or pocket seam could be used.
[0291] The basic elements of bag cartridge 20, bag 11, bag compact
21, collar 12 and carton 14 admit of considerable variation--which
is explored, albeit not exhaustively in the drawings, which
concentrate upon simpler formats believed generally
self-explanatory on their own account and in conjunction with the
component list footnote hereto.
[0292] Thus FIGS. 1A-1C reflect a basic bag cartridge.
[0293] FIG. 1D a rolled bag sheath and pull-off deployment
refinement for bag roll about (or alongside) a bag neck axis.
[0294] FIGS. 2A-2B reflect bag cartridge installation in a carton
aperture to preface bag inflation and fill.
[0295] FIGS. 3A-3D reflect an installation sequence.
[0296] FIGS. 4A-4D reflect clip-action retention of bag cartridge
collar in a carton aperture--reliant upon clip material
resilience;
[0297] FIGS. 5A-5D reflect clip action using carton edge
resilience;
[0298] FIGS. 6A-6D reflect a combined slot and clip action for
collar location, with reliance upon carton edge resilience;
[0299] FIGS. 7A-7D reflect a collar rim with depending fastener
spikes for insertion into carton top panel perforations;
[0300] FIGS. 8A-8D reflect a continuous collar edge re-entrant
profile for carton aperture edge retention, along with depending
collar to create a reception pocket for a collapsed bag;
[0301] FIGS. 9A-9D reflect bag multiple stacked offset fold for
combined downwards and sideways deployment upon inflation and/or
contents fill;
[0302] FIGS. 10A-10C reflect dual slotted bag cartridge collar
mounting in carton top and side slot in overlaid top flap panels;
reliance is thus not place upon a collar clip action as such nor
undue carton edge deflection; but an overall carton closure is
achieved;
[0303] FIGS. 11A-11G reflect slot mounting of a bag cartridge
collar in both carton top and side panels, with a variant carton
top flap panel configuration;
[0304] FIGS. 12A-12F reflect bag cartridge retention with a collar
locking flap with lock pin through carton side wall
perforations;
[0305] FIGS. 13A-13C reflect resiliently deformable bag cartridge
collar upstand with side shoulders for carton aperture
location;
[0306] FIGS. 14A -14I reflect a rotary locating and retention bag
cartridge collar configuration, with interlocking of a depending
spill lip;
[0307] FIGS. 15A-15E reflect active collar pop/flip up-down action
by a reversible conical collar floor profile, along with a
cylindrical barrel rolled bag profile;
[0308] FIGS. 16A-16D reflect a, bucket-style BIB format with large
neck spanning most of the footprint;
[0309] FIGS. 17A-17C reflect mechanised insertion and co-ordinated
bag inflation and/or contents fill;
[0310] FIGS. 18A through 20C detail anti-torque provision.
[0311] Installation--Operation
[0312] It is envisaged that a light-weight, `pick-and-place`
robotic arm 81 mounted upon a traveller rail 83, would pick up a
pre-prepared bag cartridge 20 from a storage dispenser, such as a
feed chute, or a pre-packed matrix tray assembly (not shown*). The
bag cartridge 20 would be gripped by the neck 13 or collar 12 and a
temporary sealing connection made to a pneumatic supply in
readiness for bag inflation.
[0313] Selected bag cartridge 20 would then be carried to a carton
14, aligned and inserted--by, say, a translational and/or
rotational (twist) action into a carton aperture 24.
[0314] A precise pneumatic pulse would be applied to inflate and
deploy the bag 11 until firmly and snugly up against a carton 14
inner walls. The operation would allow controlled bag positioning,
orientation and deployment.
[0315] Bag Cartridge Retention
[0316] Bag cartridge retention is desirably supplemented by bag 11
inflation and/or contents fill. Thus, say, a bag top shoulder could
bias collar locking--say, from below.
[0317] A larger collar could allow bag cartridge utilisation for
BUCKET BOX.TM. style containers, with an access aperture span at,
or close to carton footprint.
[0318] FIGS. 16A-D reflect this.
[0319] Larger collars and apertures offer even greater control over
bag location and orientation, for satisfactory and consistent
deployment. Diverse closure styles, not necessarily screw closures,
but flip lids, could also be adopted, say to mirror user
familiarity with metal cans or plastics tubs or buckets with
integrated handles.
[0320] Wine Box
[0321] A closure with control valve, such as a wine box ON/OFF tap
stopper could be substituted. A pop-up, retractable neck or spout
could be contrived with bag 11 inflation and/or fill--so the bag 11
provides a spring cushion support. A conical profile, resilient
collar upstand could impart a spring up or down action to a captive
bag neck. For wine-box use, a tap stopper could be carried. Neck
installation mid-carton footprint would provide centrally disposed
access. FIGS. 15A-E explore an example.
[0322] Anti-Torque
[0323] A rectangular or flat-sided collar 12 profile could locate
within a rectangular carton top panel aperture--for anti-torque
resistance to screw closure tightening upon fitment.
[0324] Cartridge Wrap
[0325] A one-sided or overall cartridge thin layer, peelable
(shrink) wrap may be fitted for secure pre-installation. A
frangible sheet gauge, allows rupture upon bag inflation and
unroll/unfold without impediment.
[0326] Grip or Handle
[0327] With due consideration to entrainment clip loading and top
panel closure security, a locating collar profile may incorporate a
finger grip recess or cut-out to the inside of a bag neck, to
facilitate carton tip and pour. Alternatively, a recessed, but
pull-up, movable handle may be incorporated in the collar--if cost
considerations allow. Handle or profiled finger grip cut-outs may
also feature in carton wall panels.
[0328] Neck/Spout Disposition
[0329] A neck or spout may be offset to one side of a bag top for
larger capacity bags lending themselves to tip and discharge pour
from one side. For smaller, say milk or juice, carton sizes readily
grasped single-handedly, a neck may be disposed more centrally, say
marginally to one side of a longitudinal (upright) axis.
[0330] Bucket or Bin
[0331] For a more squat container profile, such as a bucket or bin,
a larger span bag neck and locating collar would suit. A top
opening and closure might span a major part, if not the entirety,
of a container footprint. The collar could then play a greater
structural role in the overall container.
[0332] Bag Seam Disposition
[0333] Bag panel fabrication (weld) joint (reinforcement) seams may
be co-operatively disposed with carton corners or panel junctions.
Thus, say, a bag seam may be disposed diagonally between opposed
carton corner edges.
[0334] Bag Orientation+Deployment
[0335] Bag orientation is facilitated by collar alignment upon
collar 12 insertion into a complementary carton aperture 24 and bag
11 deployment by pneumatic inflation. Collar 12 and bag neck 13
interfit and orientation are explored in FIGS. 18A-C.
[0336] An individual JERRIBOX(.TM.) BIB container 10 features an
outer carton 14 enshrouding an internal bag liner 11, with a
protruding neck or spout 13 entrained by a location and retention
collar 12. Collar 12 is configured as an open-sided shallow tray
29, with upstanding peripheral side and rear walls 27 with top rim
flange 28 surmounting a carton top panel 25/32/37. An open front
face is thus exposed between out-turned front face flanges
surmounting a carton front wall panel 33. This provides clearance
for contents discharge pouring from neck 13 and allows drainage of
spillage containment upon collar floor 29 by collar walls 27. An
optional depending spill lip flange also wraps the upper margins of
carton front face. A collar floor 29 upstand 17 interacts with a
neck 13 base shoulder retention ledge, rim or shoulder 15. Upstand
17 depth is chosen to accommodate carton wall thickness, whether
solid or corrugated.
[0337] Carton 14 features an inset top recess at one side. FIGS.
18A-C show a rectangular aperture 34 in carton top seat or step,
with an instep ledge 85, accommodates the collar 12 tray profile,
without protruding above carton top (closure flap) panel 84.
[0338] Anti-torque features of bag neck 13 and collar 12 are more
apparent from FIGS. 18C and 18*D. Thus an aperture 16 in collar 12
has a shallow flared rim upstand with a series of circumferentially
spaced radial notches or slots 18 to accommodate corresponding
radial tongues or ribs 19 at the base shoulder of back neck 13.
[0339] Co-operative tongue/rib 19 and notch/slot 18 interaction can
also serve for collar 12 entrainment upon bag neck 13, with carton
wall sandwiched therebetween--as is more apparent from FIG. 18B.
Thus a marginal interference fit between ribs 19 and slots 18 could
be admitted.
[0340] Rotary indexing and entrapment of neck 13 and collar 12
could also be contrived by complementary interfit of collar upstand
17 and neck shoulder 15. That is ribs 19 and slots 18 could
temporarily align for collar mounting then misalign for collar 12
capture. Modest bag 11 pre-twist and then relaxation rotation would
suffice to accommodate such indexing. Alternatively, a separate
locking collar or circlip (not shown) could be fitted to neck 13
after collar 12 fitment, to retain collar 12 securely in place.
[0341] Only a marginal local base stem (shoulder) portion of neck
13 below closure cap location threads need have locating ribs 19.
Ribs and slots alternate on both collar 12 aperture 16 and neck 13
stem. Effectively, complementary serrated or `dog-tooth` neck 13
stem and collar 12 aperture 16 profiles co-operatively inter-fit
and interact.
[0342] A bag 11 and carton 14 assembly sequence, culminating in
capture of bag neck 13 by locating collar 12 is reflected in FIGS.
21A through 21D. Reliance is placed upon juxtaposition of neck 13
of a pre-collapsed bag 11 with a corresponding aperture 24 in a
carton top flap panel .
[0343] The carton 14 is pre-assembled as a sleeve wrap and
collapsed bag 11 inserted from one open end. An alternative
envisaged in a companion patent application of the Applicant is
carton 14 wrap about a web fed flat bag 11.
[0344] FIG. 19C shows collar 12 presented to pre-fabricated instep
in carton 14 top panel, ready to receive and locate protruding bag
neck 13.
[0345] FIG. 19A reflects a collapsed bag 11 in collapsed flat-pack
carton 12 sandwich with protruding aligned bag neck 13 located--and
held captive by--collar 12, ready for neck closure cap 38
(threaded) fitment.
[0346] FIGS. 20A-B depicts closure cap 88 fitment--albeit in
practice a closure cap would not be fitted until bag contents fill
within a 3D erected carton.
[0347] Thus, more realistically, both FIGS. 21A and 21B could be
regarded as relating to erected and filled 3D BIB cartons.
[0348] In principle, a pre-fitted closure cap 88 could be inserted,
along with bag neck 13--with collar 12 aperture 24 sized to pass
over it, so a closed rather than open-ended bag neck is located.
That said, again, closure 88 fitment is traditionally post fill--so
removal pre-fill and reinstatement would be additional--and
redundant--steps, particularly for carton assembly close to a fill
station. A temporary cap might be installed to prevent
contamination of bag inner capacity. Alternatively, a temporary
neck cap seal, removed and discarded or punctured upon fill, might
preserve bag internal condition--say for contents for human
consumption, such as edible oils. A sterile bag could thus be
contemplated.
[0349] FIG. 24A shows a split contents box of twin juxtaposed bags
with respective neck collars at opposite sides. Such an arrangement
might be used for complementary products, such as different fruit
juices, or red and white wine.
[0350] FIG. 24B shows a multiple--in this case quadruple--segmented
BIB variant with triangular footprint quadrants nestled within an
outer rectangular format. Graphic delineation and/or background
colour infill could express the sub-division visually, but within a
common contiguous carton shell. In use the carton would simply be
turned to present a selected quadrant neck for access. A multi-head
fill line (not shown) might be used for simultaneous fill of
respective quadrant contents.
[0351] A discrete cruciform footprint liner might be located
between internal bag quadrants, for mutual isolation and
(end-to-end) stiffening, bracing and support. Segmentation of the
carton itself is an option--with discrete carton quadrants (with
respective internal bags) entrained within, say, a shrink-wrap
sheath. Again, each quadrant has a dedicated neck, location and
retention collar.
[0352] Collar profiles admit of variation from rectangular
profiles, as explored in FIGS. 25A through 25F. Collar 12 and neck
13 would be profiled to suit target contents fill and dispensing.
FIG. 3C depicts the diversity of potential flowable content forms,
including--but not limited to--liquids, gels, pastes, chunks,
tablets, capsules, pellets, granules, flakes and powders. Indeed,
subject to test, any fragmented material form could be
considered--with appropriate sizing and shaping of bag access
aperture. Thus, for example, apertures representing a much large
proportion of a carton end might be adopted to facilitate free-flow
discharge--or even insertion of a ladle or scoop. Provision might
be made for bag or even overall carton squeeze locally to reduce
cross-section and promote contents discharge--as with, say,
pastes.
[0353] Neck/Spout Disposition
[0354] A neck or spout may be offset to one side of a bag top for
larger capacity bags lending themselves to tip and discharge pour
from one side. For smaller, say milk or juice, carton sizes readily
grasped single-handedly, a neck may be disposed more centrally, say
marginally to one side of a longitudinal (upright) axis.
[0355] Bag Seam Disposition
[0356] Bag panel fabrication (weld) joint (reinforcement) seams may
be co-operatively disposed with carton corners or panel junctions.
Thus, say, a bag seam may be disposed diagonally between opposed
carton corner edges.
[0357] Mix `n` Match
[0358] Features described may be variously mixed and matched to
suit operational requirements. It is not feasible to show every
such permutation or combination of features.
[0359] Phrases bracketed--vis {. . . }--alongside claim
numbering--are for ease of reference and as such form no part of
claim interpretation or scope.
Variant Diversity
[0360] Carton Configuration
[0361] Although predominantly rectangular or polygonal flat sided
cartons have been described and illustrated, as more readily
fabricated from initially flat sheet material, curvilinear forms
might be contemplated. A prime curved form would be a cylindrical
wrap--say about plastics end caps with integral bag location collar
functionality.
[0362] Indeed full-span end caps could dictate an outer
cross-sectional form or footprint, with variable spacing to
accommodate differential sleeve depth. This could apply to diverse
end cap profiles, including rectangular, polygonal segmented,
arcuate circular, oval or conic sections. An intervening sleeve set
between opposed end caps could be simpler than a conventional
carton, with potentially less material usage or waste and more
flexible assembly. A carton sleeve could be severed to a desired
length from a continuous extruded tube.
[0363] Pre-formed tubes of pre-impregnated or pre-sealed material,
such as employed with TETRAPAK(.TM.) cartons could be employed.
Along with a sealable bag, this could provide a measure of double
seal protection--albeit contingent upon sealing interfit of end
caps and intervening sleeve.
[0364] Bag-Liner Configuration
[0365] Similar considerations of variant form apply to the bag or
liner. Whilst generally complementary bag and carton forms may be
desirable to usable maximise internal volume or capacity,
disconformity may be employed to leave free pockets for other uses.
An example would be supplementary discrete cushion bags for impact
or drop resistance--putting to advantage a gap between carton and
bag walls.
[0366] Unification
[0367] Although bag and carton have been shown as discrete
elements, carton panels and bag walls could be conjoined or united
locally, or even integrated. Such unification could be upon
inter-assembly and bag pre-inflation or contents fill.
[0368] Sleeve Bag
[0369] A bag could be configured as a hollow sleeve, admitting both
internal and external carton sleeve disposition in an overall
carton-bag-carton sandwich. Such a composite sandwich form could be
inflated or contracted whilst retaining relative disposition of
elements. A bag neck could be disposed in mid carton wall span. A
neck collar could be configured as a surrounding guidance funnel
into the back neck. This could be helpful for drainage into a bag
from an overlying reservoir. Thus, say, a used oil container could
be contrived in a sump drain format for sealed waste disposal.
