Referring to the drawings . . .

Constituents

FIG. 1 depicts an assembly sequence flow chart of principle constituent BIB elements, namely:

• • box or carton 11;
  • bag 12;
  • locating neck collar 14—per GB0314815;
  • (optional) discrete (side/top) handle 13;

The bag 12 features an integral neck pourer or spout for contents fill and discharge.

A preferred bag manufacture (not shown) produces a continuous web of mutually edge-entrained, collapse folded bags.

That said, discrete bags (say either produced individually or separated from a web) can be used, as discussed in later embodiments.

Handle—Handling

Generally, for handling ergonomics, discrete neck collar 14 and handle 13 are disposed at opposite sides of a carton body 11.

A handle allows a user both to support filled weight and control the angle of tipping—and so rate of pouring.

A tall (say, pull-up) handle upstand at the neck collar 14 is feasible.

Supplementary handle cut-outs in the body (that is top and/or side walls) of carton 11 are readily provided upon carton blank die cutting.

In some variants, the collar 14 and handle 13 could be integrated—say by adopting a common (vacuum) moulding plate or strip.

Such an integrated handle and neck collar could form an overall carton top plate, providing shape bracing and support to a stacked overlying carton.

Flat Pack Sub-Assembly

These various elements are brought together in a compact collapsed, flat-pack sub-assembly 20—for ‘dense’ (ie space efficient) bulk stacking and packing, to supply a remote fill station.

Final pack erection and completion (closure and sealing), to a pre-fill assembly 30, can be undertaken upon sub-assembly 20 in a subsequent distinct step at a fill station, on a user's premises, upon draw-down from a local store or repository.

Thus a fully erect 3-D volumetric form is not assumed until necessary to accommodate contents.

In this schema no wasteful void space is consumed in transport or storage until call-off just preparatory to fill.

However, if space is not at a premium, empty erected forms can be transported and stored—relieving the fill plant of the need for an inflation/erection station.

Automated Assembly

Although special-purpose machinery and operation is involved with BIB, certain (sub-)assembly steps can be derived by adaptation of conventional case erection packaging machines and technology.

This represents an economic advantage if a user is converting from traditional semi-rigid walled cartons to BIB, but already has certain packaging equipment.

The drawings are thus intentionally merely indicative and illustrative of broad principles, rather than necessarily detailed engineering solutions.

Sub-Assembly

FIGS. 2A (conveyor side elevation) and 2B (sequenced flow chart) depict in more detail creation of sub-assembly 20 of FIG. 1.

Bag Web

Bags are produced as continuous web 55 of conjoined individual bag elements 51.

A web 55 of conjoined bags 51 is stored concertina-folded in a cassette store or repository 50.

The bags 51 are progressively retrieved from the store 50 by orderly unfolding and presented in a line, with necks 52 uppermost, upon a conveyor bed 80.

Carton Stack

Multiple discrete cartons 41 are stacked, one above another in corresponding orientation, as individual cut pre-folded carton blanks, in a cassette store 40, ready for individual pick-off and deposit upon a corresponding individual bag 51.

Carton Blank

FIG. 9A shows laid-flat carton blank detail, with extended top 42, 48, 56 and bottom 57, 58 closure flaps and optional handle cut-outs 44.

The span of bottom side flaps 57 allows mutual overlap upon flap fold up—to cover the whole of the base area.

Bottom end flaps 58 then fold over—to provide three complete layers of material on the base and thus bolster carton robustness.

End flaps 58 are off-set (i.e. one longer than the other) to mirror the off-set of the top flaps 42, 48 in accommodating the collar 14.

Thus a single off-set tape machine (not shown) may be used (simultaneously) to seal both top 42, 48 and bottom 58 flaps.

Neck Aperture

A carton top flap 42 has a pre-cut neck aperture 43 to receive and locate a neck 52 of a bag 51.

Neck aperture 43 diameter is sufficient to pass, with modest local distention, and remain entrained under, a retention rim (not shown) upon bag neck 52.

Radial slits (not shown) about aperture 43 create locally a segmented periphery for such distension.

Pick'n Place

A pick'n place arm (not shown) deposits an individual carton 41 upon an associated bag 51, with the help of lateral conveyor guides 81 and an index locator finger (not shown) for a bag neck 52.

By drawing bag web 50, successive bags 51 are 00indexed, incrementally or continuously, over conveyor bed 80, through successive work stations for carton 41, collar 14 and (optional) handle 13 fitment.

Collar

A cassette store 60 of stacked pre-fabricated (eg vacuum moulded shell) neck collars 14 is disposed over the conveyor 80 to deposit an individual collar upon an upstanding bag neck 52.

Collar 14 is superimposed upon a carton top flap 42.

A collar aperture 61 is sufficient to pass, with modest temporary local deformation, over neck retention rim—so that both carton top flap 42 and collar 14 are held captive between retention rim and bag 51.

Collar aperture 61 profile can be adapted—say with radial peripheral slits or otherwise segmented—to facilitate local distension for fitment and to secure bag neck 52 when a screw cap is applied.

The effect is to impart an anti-torque or torque resistant entrainment of bag neck in relation to (screw) cap closure fitment.

Handle

A supplementary discrete handle 13, can be fitted to a carton top flap 42 and side edge 45 at a handle installation station 90.

A pre-fabricated (moulded) ‘lay-flat’ profile is convenient for handle 13.

Such a handle 13 can be secured by local adhesive bonding.

In addition, or alternatively, reliance can be placed upon handle cut-outs in the carton body.

In some variants, handle 13 could be integrated with collar 14—in which case a combined store and mounting station could be contrived.

Concertina Stacking

Carton 41, bag 51, neck collar 14 and (optional) handle 13 are fitted to create a sub-assembly 20.

A succession of sub-assemblies 20 is mutually entrained in a sub-assembly string or web 71,

Web 71 is drawn into a concertina-folded stack in a sub-assembly cassette store or repository 70.

Sub-Assembly Review—Overview

Flat Pack

The overall assembly sequence involves:

• • bringing together into juxtaposition a collapsed bag 51 and collapsed carton 41,
  • with insertion of an intervening location collar 14 according to GB0314815,
  • so preserving a compact collapsed flat pack individual sub-assembly 20 form in a sub-assembly string 71.

A bag neck 52 of an individual bag 51 is orientated upward as an upstand for registration and location of an aperture 43 in a top flap 42 of a carton 41.

An automated BIB carton assembly line 100 is fed by a continuous web 55 of bags 51 and a stack 40 of collapsed cartons 41.

A conveyor 80 draws the web 55 along an assembly path, at which successive individual cartons 41 are extracted from the stack 40 and laid upon an associated bag 51.

A carton 41 is presented to an underling bag 51 with a top flap 42 and neck locating aperture 43 deployed in mutual registration.

Side and/or end flaps 46 are in-turned and joined, using tab 19, to create a carton sleeve or wrap 47 about each bag 51.

This leaves top 42, 48, 56 and bottom 57, 58 (closure) flaps to be deployed and mutually entrained—upon conversion from a 2-D collapsed form to a 3-D erect form.

A collar storage cassette 60 with a discharge driving plunger (not shown), delivers and installs individual collars 14 to each bag neck 52, with a spring clip insertion and location action.

Collar 14 effectively holds the carton top flap 42 with neck locating aperture 43 captive with the bag neck 52—and thus entrains overall carton 41 and bag 51.

The bag neck 52 serves as a locating upstand, to help preserve bag 51 and carton 41 registration and alignment—also aided by lateral conveyor guides 81.

Thus successive cartons 41 are entrained upon respective individual bags 51 of the bag web 55.

The entrained bag web 55 and carton ‘string’ 71 is concertina folded in a storage cassette 70.

Storage cassette 70 is conveniently a portable container, which can be transported to a remote final assembly and fill station, as now described.

Collapse Folded Flat Pack Sub-Assembly

The overall outcome of FIGS. 2A and 2B sub-assembly stage is a compact, collapsed-folded, flat-pack of mutually entrained or captive bag 51, carton 41, neck collar 14 and (optional) handle 13, in a sub-assembly string 71.

Final Assembly & Erection

FIGS. 3A and 3B depict final assembly and erection to transform a 2-D collapsed flat pack sub-assembly 71 of FIG. 2 into an erected fully assembled 3-D form 150 ready for contents fill.

Preparatory Bag (Test) Inflation

In this schema, an intermediate preparatory bag (test) inflation is undertaken preparatory to carton 41 closure fully to envelop the bag 51.

Contents Fill

In an alternative schema, initial bag 51 inflation is through contents fill—that is bypassing a preliminary test inflation.

The sub-assembly cassette store 70 is emptied by progressively withdrawing a sub-assembly string 71 based upon an original bag web 55.

Individual bags 51 are presented to a preliminary inflation test station 110 with necks 52 uppermost.

This orientation also corresponds to the stacking orientation at the conclusion of the sub-assembly stage of FIG. 2.

Bags 51 are supported by a conveyor bed 120.

Simultaneous connection is made to multiple bag necks 52 through multiple individual valve caps 111, with respective umbilical feed pipes 112 to an air pressure supply 113, through a rotary swivel connector valve 114 (detailed in FIG. 4).

Individual bags 51 are captured with a valve cap 111 and a retention rim locating collar (not shown) to bear bag 51 and contents weight.

Until fitment of valve cap 111, and capture by a neck retention rim location collar, successive bags 51 remain mutually entrained in original continuous bag web 55—and are thus to an extent self-registered.

Upon valve cap 111 and rim locator fitment, bags 51 are mutually severed—so breaking or fragmenting the former continuous web 55.

Severance is conveniently undertaken along a pre-scored weakening line, using a (slicing rotary or guillotine) knife blade (not shown).

Upon mutual severance, individual bags 51 are free to adopted independent positions and orientations in relation to successive, formerly adjoining, bags 51.

Whilst a bag 51 is held captive by its neck 52, its body is free to hang down—suspended by retention rim, itself configured to withstand such support loading.

Similarly, a carton 41 is held captive by entrapment of its top flap 42 beneath the bag retention rim.

However, the bulk of carton 41 is free to swing down about a top flap corner edge fold 49.

Air (Pre-Fill) Inflation

Bag 51 and carton 41 gravity suspension is triggered by air pressure feed to cap valve 111—progressively to inflate, and so distend bag 51 walls from a collapse folded 2-D condition to an erect 3-D form.

Air Pulse

An air pulse can be employed to disturb initial juxtaposed bag 51 and carton 41 disposition.

Successive individual separated bags 51 are carried upon conveyor 120 to an end flap closure station 130 and onward to a contents fill station 140.

Multiple Pre-inflation/Fill

FIG. 4 shows a plan view of multiple simultaneous pre-inflation and/or fill detail in the erection and final assembly sequence outlined in FIG. 3A.

A spider web array of fill lines 112 radiates from a common central feed head 113 with a swivel joint and seal.

Individual fill caps 114 traverse a continuous orbital track 120.

Concertina Folded Bags and Cartons

FIG. 5A shows an alternative sub-assembly sequence to that of FIG. 2A.

In this arrangement, both bags 51 and carton blanks 41 are brought together from separate respective stacked concertina folded webs.

Once a carton 41 has been correctly located onto bag 51, it will be severed from subseqent carton 41 to enable individual carton 41 fold around a respective bag 51, remaining in bag web 55.

As before, neck retention collar 14 is attached and the resulting sub-assembly 71 is concertina folded for transport or storage.

FIG. 5B shows a follow-on inflation/fill final assembly sequence to FIG. 5A sub-assembly, with options supplementing basic steps of FIG. 3A.

These options are depicted schematically as interventions—themselves detailed in FIGS. 6A and 6B.

Again, concertina folded sub-assemblies 71 are drawn from their stack and attached to an air hose/feed line before being severed from the next in line.

A bag 51 is then inflated/filled while the assembly is supported by its retention collar 14.

This allows carton 41 to take shape as bag 51 volume increases.

A final step is to close and seal top 42, 48, 56 and bottom 57, 58 carton flaps.

Cushion Floor

FIG. 6A shows an optional final assembly stage—prior to closure of bottom carton flaps 57, 58—of insertion of a cushion floor 15.

Such a floor 15 may be comprised of corrugated cardboard or like material, to help protect the bottom of bag 51 inside carton 41.

Thus, carton 41 base puncture or crush may be accommodated by the cushion flooring 15 and thus preserve the bag 51 intact.

Reinforcement/Bracing Sleeve

Alternatively, or additionally, a reinforcement or bracing sleeve or liner 16 may be inserted into carton 41 before final closure, as depicted in FIG. 6B.

Bracing sleeve 16 bolsters overall carton strength and rigidity for larger and heavier capacties.

This is achieved without adoption of a higher or thicker grade cardboard for the entire carton body.

Thus, a bracing sleeve could be corrugated to provide vertical stacking strength, whilst an outer (non-corrugated) carton body provides splash and water protection.

Conversely, a corrugated carton body could make a bracing sleeve redundant.

Sleeve 16 also preserves overall rectangular carton form, for stacking consistency and protects bag 51 in the event of carton 41 side impact.

Stacking Plates

An optional step of grouping and packaging multiple BIB cartons after individual carton (150) erection is reflected in FIGS. 7A and 7B.

Top and bottom stacking plates 17 sandwich multiple—in this case dual or paired—adjacent BIB cartons (150) in a rectangular configuration.

Plates 17 are held together by tie bands 18 wrapped around the set at several points.

A final multiple (in this dual or paired) pack cluster option is depicted in FIG. 7A.

This principle may be employed not for mutually entraining and securing identical BIB cartons (150)—but also sets of different sized cartons, scaled and stacked to form a substantially rectangular outer form—as shown in FIG. 7B.

Web Rolled Bags and Cartons

FIGS. 8A and 8B show a variant of FIGS. 5A and 5B, whereby the bags 51 and cartons 41 are brought together from individual web rolls 91, 92.

Thus, bags 51 are successively unravelled from roll 91, whilst cartons—possibly of synthetic plastics material—are unravelled from roll 92.

Roll 92 feed is like unsuitable for corrugated cardboard material, which embodies a laid flat set in production.

However, roll feed might be tenable for single layer sheet or card or synthetic plastics, or even corrugated plastics where corrugations run parallel to the roll axis.

A sufficiently large roll diameter is envisaged to avoid material adopting a set curvature.

Carton Construction (Pre-Bag Insertion)

FIGS. 9A through 9H detail alternative BIB construction and/or (pre-)assembly—independently of and prefacing bag introduction.

Generally, carton 11 is almost fully formed before bag 12 is inserted and collar 14 attached.

An assembly sequence comprises:

• • fold carton blank 11, bringing side panels 46 around to form open-ended wrap 47;
  • (edge) seal side panels 46 together, using tab 19;
  • fold down top flaps 56, 42, 48 and seal in place;
  • insert bag 12 into carton 11 through open carton bottom;

{in practice, a carton collar could be lowered upon an inflated bag}

• • attach collar 14 to bag 12 through carton aperture 43;
  • close bottom flaps 57, 58 and seal in place.

Optionally, a pre-fabricated handle could also be fitted upon the carton—as shown in FIG. 9G.

Alternatively, an integrated handle and collar top-plate could be fitted—as shown in FIG. 9H.

Carton Construction Around Infated/Filled Bag

FIG. 10 shows an alternative BIB assembly of bag 12 pre-inflation/fill and carton 11 build around it.

Sub-Assembly Construction

FIGS. 11 A through 11 C show sub-assembly from a bag roll 91 and individual carton blank elements 41.

Each successive individual bag 51 is overlaid with a respective carton blank 41.

Carton 41 is then folded in half around bag 51 until side panels 46 lie adjacent each other.

Carton side tab 19 is then glued or otherwise secured to adjacent side panel 46 edge.

Finally, collar 14 is attached to bag 51 and carton 41 to secure these elements together.

FIG. 12 shows a stack of multiple individual BIB sub-assemblies 20.

Bracing Sleeve Insertion

FIGS. 13A through 13C illustrate insertion of bracing sleeve 16 into carton 41.

Bracing sleeve 16 may be of toughened cardboard material or corrugated as detailed in FIG. 13C.

Bracing sleeve 16 is preferrably profiled to nest within carton 41 body and provide extra strength at the edges and corners—as illustrated in FIG. 13B.

Corrugated Carton

The entire carton body 72 may be constructed from corrugated material—as shown in FIGS. 14A and 14B.

This may negate the need for an additional bracing sleeve in applications where box robustness is of prime consideration.

Corrugated cartons 72 may also be useful in applications where the carton does not require to be waterproof.

Collar Release Valve

FIGS. 15A and 15B illustrate how collar 14 recess may act as a safety release valve when the BIB is dropped.

As a carton 41 is crushed from beneath, internal bag 51 is forced upwards.

This forces out recess panel 73 which in turn pushes out attached collar 14 with intrained bag neck 52.

As can be seen from FIG. 15B bag 51 then has more room in which to move away from the crushed carton below.

This may mean bag 51 can stay intact despite carton 41 crush.

Cushion Pad

A cushion pad 74 may be accomodated within carton 41 as shown in FIG. 16.

This cushion pad 74 may be filled with air and placed on top of bag 51, adjacent the underside of recess panel 73.

As air or gas is more readily compressed than liquid, this cushion pad 74 may crush before bag 51 liquid contents.

Integrated Bag & Collar

A bag may be integrated with a collar 82.

This may then be inserted into a carton 83 as shown in FIG. 17.

Carton 83 is provided with an opening 84 into which bag 82 is fed until attached collar seals opening 84.

Collar & Bag Restraint

Collar 14 and entrained bag neck 52 are restrained from rotational movement by carton 41 recess profile.

Thus, as a screw cap 62 is applied, the resulting torque does not twist the collar 14 or bag 51 inside the carton 41—as illustrated in FIG. 18.

Moulded Plastic Carton

FIGS. 19A and 19B show a variant carton 93 configured from a moulded plastics sheet.

Collar 14 is thus integrated into the carton 93 form, negating the need for attachment of an additional collar 14 element.

Other features may also be moulded into a plastic carton blank.

FIGS. 20A and 20B show a variant of the above with a plastic handle cut-out incorporated into carton 94.

‘Mix and Match’ Features

Generally, in the embodiments, where feasible and appropriate, features may be selectively ‘mixed and matched’ to suit circumstances—albeit it is not feasible to describe every such feature combination.
