Description
TECHNICAL FIELD
[0001] The present invention relates, generally, to wicketed bag
manufacturing bag processes and, more particularly, to methods of
making wicketed bags having secondary or external compartments,
such as kangaroo pouches, and the like.
BACKGROUND
[0002] Wicketed bags have traditionally been used for packaging an
assortment items, such as purchased consumer products, newspapers,
magazines, advertising flyers, and other commercial materials.
Printed materials are typically widely distributed to large numbers
of customers at both residential and commercial locations. To take
advantage of the advertising potential associated with the
wide-spread distribution of such materials, external compartments
have been added to the wicketed bags. The external compartments or
pouches are used to enclose various articles, such as advertising
literature and product samples, and the like. In the newspaper
industry, for example, newspapers are delivered to subscribers in
wicketed bags configured to include sealed pouches for enclosing
additional articles. It is common in the newspaper industry to have
the product samples or printed materials inserted into a kangaroo
style pouch. The kangaroo pouch is either formed on, or an integral
part of, a lower portion of the wicketed bag. Typically, the
newspaper distributors receive the wicketed bags having articles
already sealed in the pouches. The distributor then inserts the
newspapers into the wicketed bags for delivery to subscribers.
[0003] To provide users such as retailers, event marketers,
newspaper publishers, and the like with wicketed bags having
articles enclosed within the kangaroo pouch, manufacturing
processes for fabricating wicketed bags having external
compartments have been developed. Typically, wicketed bags are
fabricated by high-speed bag machines, known as wicketer machines.
These machines operate at a high speed using a roll of plastic film
that is known in the industry as a web. The web is processed in the
bag machine to form a compartment. The web is first folded to
produce a bottom edge and then cross sealed and cut to form
individual wicketed bags. Once the wicketed bags are formed, they
can be suspended from a wicket holder for delivery to a media
distributor or other user.
[0004] Several techniques have been developed for creating an
external compartment on the outside of wicketed bags. Many of these
techniques include the use of an additional web that is brought
together with the web used to fabricate the wicketed bag. The
external compartment is then formed by heat sealing the second web
to the first web. Other methods use sophisticated folding and
sealing techniques of a single web or multiple webs to create two
compartments. The fabrication method produces wicketed bags having
a large internal compartment and a smaller external
compartment.
[0005] Once the wicketed bags having the external compartment are
fabricated, articles, such as printed materials or advertising
samples are inserted into the external compartments. The bags can
have articles inserted into the external compartment immediately
after fabrication, or the bags are transferred to a third party for
insertion of the articles into the external compartment. The
placement of the articles into the external compartment is
typically carried out by hand or by an automatic insertion process.
After the articles are placed in the external compartment, the
compartment may or may not be sealed and the wicketed bags are
delivered to a media distributor, such as a newspaper distributor,
for placement of newspapers in the larger internal compartment of
the wicketed bag.
[0006] Overall, the process of fabricating wicketed bags having
articles enclosed within an external compartment involves first
fabricating the wicketed bag and the external compartment, then
inserting articles in the external compartment or delivering the
wicketed bag to a third party, who then inserts articles into the
external compartment. The insertion of articles is typically done
by hand, after which the external compartment may or may not be
sealed. Lastly, the bags containing the articles are shipped to a
marketer or a media distributor for further use. In the case of a
media distributor, the distributor inserts newspapers or
advertising into the wicketed bags for delivery to a customer or
subscriber.
[0007] The process of creating wicketed bags with external
compartments, and inserting articles into the compartments is
lengthy and labor intensive. Although bag forming processes have
been developed for fabricating wicketed bags having external
compartments, human intervention is often required at the process
stage between bag fabrication and delivery to a marketer or
distributor for final processing.

DETAILED DESCRIPTION
[0026] Shown in FIGS. 1a and 1b is a wicketed bag 10 having an
external compartment 12 attached to an outer surface 14 of wicketed
bag 10. Wicketed bag 10 is preferably fabricated from a
thermoplastic material and has a folded edge 16 and sealed edges 18
and 20. An internal compartment 22 in wicketed bag 10 is created by
folding the thermoplastic material to create folded edge 16 and
cross sealing the thermoplastic to form sealed edges 18 and 20.
[0027] FIG. 1b is a cross-sectional view of wicketed bag 10, taken
along section line 1b-1b of FIG. 1a. As illustrated in FIG. 1b,
external compartment 12 is attached to a lower portion 24 of
wicketed bag 10. External compartment 12 contains an article 26
within a compartment 28 of external compartment 12. External
compartment 12 includes a closure seal 30, which can be a
perforated seal, in an upper portion of external compartment 12. In
other embodiments, closure seal 30 can be a lap seal, heat seam,
grooved seal, folded flap seal, and the like.
[0028] In the embodiment illustrated in FIGS. 1a and 1b, external
compartment 12 is attached to lower portion 24 of wicketed bag 10
by a variety of attachment methods. For example, external
compartment 12 can be attached by an adhesive material placed
directly on either lower portion 24 of wicketed bag 10 or on the
upper portion of external compartment 12. Additionally, external
compartment 12 can be attached to wicketed bag 10 by a double-sided
adhesive tape that includes a backing material and a coating of
adhesive on both sides of the backing material (not shown).
Further, external compartment 12 can be attached to wicketed bag 10
by heat sealing the plastic materials of wicketed bag 10 and
external compartment 12 to form a continuous melt of thermoplastic
material. Further, other types of attachment mechanisms are
contemplated, such as fiber thread stitching, sewing, weaving, and
the like.
[0029] Wicketed bag 10 also includes holes 32 in an upper portion
of the wicketed bag. Holes 32 can be used to suspend wicketed bag
10 from a wicket holder, or other bag attached device.
[0030] Wicketed bag 10 and external compartment 12 are configured
to enclose a variety of articles within internal compartment 22 and
internal compartment 28, respectively. Those skilled in the art
will appreciate that the bag structure illustrated in FIGS. 1a and
1b can be used to package a wide variety of materials, including
printed materials, advertising samples, physical objects, such as
product samples, plastic bottles, promotional items, and the
like.
[0031] FIG. 2a is a plan view of a wicketed bag 34 fabricated in
accordance with another embodiment of the invention. FIG. 2b is a
cross-sectional view of wicketed bag 34 taken along section line
2b-2b of FIG. 2a. Wicketed bag 34 includes an external compartment
36 attached to an outer surface 38 of wicketed bag 34. FIG. 2c is
an expanded view of external compartment 36 detached from wicketed
bag 34.
[0032] In the embodiment illustrated in FIGS. 2a-2c, external
compartment 36 is attached to outer surface 38 of wicketed bag 34
at a position on outer surface 38 displaced away from a fold 40 of
wicketed bag 34. External compartment 36 encloses an article 42
within an internal compartment 44. External compartment 36 is
closed by a flap seal 46. Alternatively, external compartment 36
can be closed by a perforated seal, glue seam, and the like.
[0033] External compartment 36 can be attached to outer surface 38
of wicketed bag 34 using attachment techniques similar to those
described above for attachment of external compartment 12. Further,
external compartment 36 can be attached to outer surface 38 along
the entirety of an interface 48 between external compartment 36 and
outer surface 38 of wicketed bag 34. Alternatively, external
compartment 36 can be attached to outer surface 38 at only an upper
portion of the interface, or at regular or irregular intervals
along interface 48. In the illustrated embodiment, external
compartment 36 is attached to wicketed bag 34 at flap seal 46.
Alternatively, the external compartment can be attached by an
adhesive 49 to one or more locations along the interface 48.
[0034] In similarity to the embodiment illustrated in FIGS. 1a and
1b, wicketed bag 34 includes holes 50 in an upper portion of the
wicketed for attachment to a wicket holder, or other containment
device. In the embodiment invention illustrated in FIGS. 2a-2c,
article 42 can be any of a wide variety of articles including
written materials, physical objects, plastic articles, including
toys and other promotional articles, and the like.
[0035] FIG. 3 is a schematic diagram of a process in accordance
with a first embodiment of the invention for fabricating wicketed
bags having pre-packaged articles attached thereto. The processes
illustrated herein employ a variety of processing equipment known
to those skilled in the art. Accordingly, the processing equipment
is only generally depicted in schematic form. Further, many
component parts of the actual equipment used in bag machines have
been omitted to improve the clarity of the illustration.
[0036] In the illustrated embodiment, a web 52 of thermoplastic
material is fed from a roll 54 through a plough fold 56. Plough
fold 56 includes a top roller 58 and a roller pair 60. The process
illustrated in FIG. 3 can be used to fabricate wicketed bag 10
having external compartment 12 attached thereto. In the illustrated
process, external compartment 12 is pre-packaged to enclose article
26 within compartment 28 prior to being provided for attachment to
the thermoplastic material forming wicketed bag 10. In the
illustrated embodiment, a horizontal or vertical form and fill
packaging is configured to fabricate wicketed bags having
pre-packaged external compartments attached in a continuous
process.
[0037] Web 52 is continuously fed from roll 54 to plough fold 56
and is continuously conveyed in a process direction 62 at a
predetermined web feed rate. In the illustrated embodiment a
continuous series of pre-packaged enclosures is fed from a roll 66
and aligned to folded web 68. An adhesive or other attachment
device, such as a tape, and the like, is applied to an upper edge
of pre-packaged enclosure 64. In the illustrated embodiment, a hot
melt glue applicator 70 extrudes a stream of glue along an upper
edge 72 of pre-packaged enclosure 64. The feed rate of pre-packaged
enclosure 64 from roll 66 is substantially synchronous with the
transfer rate of folded web 68 and process direction 62.
Accordingly, pre-packaged enclosure 64 are brought into contact
with folded web 68 under conditions in which both pre-packaged
enclosures 64 and folded web 68 are moving in process direction 62
at substantially the same rate. A pressure roller 74 applies
pressure to a support roller 76 and provides a compression force
for adhesively attaching pre-packaged enclosure 64 to folded web
68. Those skilled in the art will appreciate that other devices can
be used for compressing folded web 68 against pre-packaged
enclosure 64. For example, pressure can be applied by a
pneumatically-actuated surface or spring-loaded mechanical device,
and the like. Further, the pre-packaged enclosures can be attached
to the upper surface of folded web 68 rather than to the lower
surface as depicted in the illustrated embodiment.
[0038] Simultaneous with the attachment of pre-packaged enclosure
64 to folded web 68, a series of holes 32 are punched in an upper
portion of folded web 68 by a perforating device 78.
[0039] Once pre-packaged enclosure 64 are attached to folded web 68
and holes 32 are punched in folded web 68, the web and the
pre-packaged enclosures are transversely sectioned by a cross
sealing device 80. Cross sealing device transversely cuts folded
web 68 and pre-packaged enclosures and simultaneously forms sealed
edges to produce individual units, such as wicketed bag 10 having
external compartment 12 attached thereto.
[0040] After separating individual units, the wicketed bags are
stacked by a bag stacking device 82 and placed on wicket holders
84. Accordingly, a process in accordance with the illustrated
embodiment produces a large volume of wicketed bags having
pre-packaged enclosures in a continuous process carried out at a
high process rate. Once the wicketed bags and pre-packaged
enclosures are separated into individual units, they can be shipped
to distributors for insertion of desired articles into the internal
compartments, such as internal compartment 22 of the wicketed bags.
Since articles are already pre-packaged in the external
compartments, the distributor or other user does not have to
provide facilities and personnel for inserting articles into the
attached enclosures. Once the process in accordance with the
illustrated embodiment, no further action is required by a user to
insert articles into the external compartment. Those skilled in the
art will appreciate that automated means can also be carried out
for inserting articles into the internal compartments of the
wicketed bag for ultimate delivery to subscribers or to
customers.
[0041] An apparatus and method for providing a continuous series of
pre-packaged articles is illustrated in FIG. 4. A continuous series
of pre-packaged articles 86 is contained within a carton 88.
Pre-packaged articles 86 are arranged in a bandolier that lays in
multiple folds within carton 88. A feed roller pulls the bandolier
of pre-packaged articles 86 out of carton 88 and transports the
prepackaged articles and process direction 62. The bandolier is
continuously fed in process direction 62 at a rate that is
substantially synchronous with the feed rate of folded web 68. In
the embodiment illustrated in FIG. 4, the bandolier of pre-packaged
articles 86 can be attached at a distal end 92 to another bandolier
of pre-packaged articles (not shown) that is fed from an additional
carton (not shown). In this way, a continuous series of
pre-packaged articles can be fed into the wicketed bag fabrication
process without the need to interrupt the process in order to
provide a fresh carton of pre-packaged articles. Those skilled in
the art will appreciate that different methods of feeding the
bandolier of pre-packaged articles can be used to draw the
continuous series out of carton 88. For example, a friction-feed
device, a conveyer mechanism, or other handling device can be
provided inside of or proximate to carton 88.
[0042] A process for fabricating wicketed bags having pre-packaged
articles attached thereto in accordance with a second processing
embodiment is illustrated in FIG. 5. In similarity to the process
embodiment described above, a continuous web 92 of thermoplastic
material is fed from a roll 94 through a plough fold 96. Plough
fold 96 folds the web into a folded web 98 that punched by hole
punch 99 and transported in a process direction 100. An applicator
102 applies adhesive 104 to folded web 98. Adhesive 104 can be a
variety of adhesive materials including epoxies, cements, glues,
and the like. Further, adhesive 104 can be delivered to folded web
98 in the form of a backing material having an adhesive layer on
the front and backside of the backing material. Those skilled in
the art will recognize that a number of adhesive tapes and labels
commonly used in the packaging industry can be employed to provide
a region of adhesive material on folded web 98. Further, rather
than place adhesive on the web, adhesive can be placed on the
articles prior to positioning on the web.
[0043] A feeding device 106 sequentially places individual
pre-packaged articles onto adhesive 104, such that a series of
pre-packaged articles 108 are sequentially positioned on folded web
98.
[0044] Once pre-packaged articles 108 are attached to folded web
98, a cross cutting and sealing process and a wicket stacking
process is carried out in a manner similar to that described above.
A cross sealing device cross seals folded web 98 and cuts the web
into individual units, such as a wicketed bag 34, where each
wicketed bag 34 has an external compartment 36 attached
thereto.
[0045] A stacking device 110 sequentially stacks wicketed bags 34
on a wicket holder 112. The wicket holder remains stationary while
the bags are stacked on a pair of wires. Once a predetermined
number of wicketed bags are stacked on a given pair of wires, the
wicket holder is indexed. The index rate is set so as to permit the
predetermined number of bags to be sequentially stacked on each
pair of wires.
[0046] In similarity to the processing embodiment described above,
once articles are attached to the wicketed bags, they can be
subsequently packaged and delivered to a marketer, distributor, or
other user. Those skilled in the art will appreciate that the
process illustrated in FIG. 5 can also be used to attach various
objects to the wicketed bags, such as plastic promotional items,
bound booklets, folded paper materials, and the like.
[0047] FIGS. 6a and 6b illustrate alternative embodiments of the
invention for delivering individual pre-packaged articles 108 to
folded web 98. FIG. 6a illustrates a shuttle device 114 that uses a
roller 116 and a friction belt 118 to deliver pre-packaged articles
108 from a stacking bin 120.
[0048] FIG. 6b is a schematic diagram of a rotary feed device 122
that delivers pre-packaged articles 108 from a stacking bin 124 and
a vacuum rotary 126. Those skilled in the art will appreciate that
other feeding devices exist and can be used to deliver pre-packaged
articles 108 to folded web 98. For example, a pick and place
machine or other type of vacuum conveying device can also be
used.
[0049] FIG. 7 is a schematic diagram that illustrates a process for
fabricating wicketed bags having pre-packaged articles attached
thereto in accordance with a third processing embodiment of the
invention. The process illustrated in FIG. 7 is substantially
similar to that of the second processing embodiment described
above. Once web 92 is fed from roll 94 through plough fold 96 and
punched by hole punch 99, applicator 102 places adhesive 104 on
folded web 98. In the present embodiment, applicator 102 places an
additional adhesive 105 at a location displaced along folded web 98
a predetermined distance from adhesive 104. Further, applicator 102
alternates the dispensing of adhesive, such that adhesive 104 and
105 are staggered on folded web 98 along processing direction 100.
Alternatively, the adhesive can be applied to the pre-packaged
articles prior to placement on the web.
[0050] A feeding device 128 provides pre-packaged articles for
attachment to both adhesive 104 and adhesive 105. Accordingly, one
group of pre-packaged articles 130 is attached to adhesive 104,
while a second group of pre-packaged articles 132 is attached by
adhesive 105.
[0051] Once the pre-packaged articles are attached to folded web
98, cross sealing and stacking operations are carried out in a
manner substantially similar to that described above with respect
to the first and second processing embodiments. The process in
accordance with the third processing embodiment of the invention
produces two groups of wicketed bags 134 and 136, each having
pre-packaged articles attached at different locations along the
outer surface of the wicketed bag. The first group of wicketed bags
134 has pre-packaged articles 130 attached in a lower portion of
the outer surface, while a second group of wicketed bags 136 has
pre-packaged articles 132 attached at an upper portion of the outer
surface. In another embodiment, the pre-packaged articles can be
attached in an alternating fashion to the left and right sides of
the wicketed bags.
[0052] Wicketed bags produced in accordance with the third
processing embodiment can provide bags having pre-packaged articles
attached at different locations on the outer surface of the
wicketed bag. When the articles are arranged in an alternating
location on the wicked bags, the wickets bags do not stack to the
same height as bags in which the articles are all at the same
location on the wicketed bags. Accordingly, by attaching the
pre-packaged articles at alternating locations, the wicketed bags
can be stacked on wicket holders 112 and handled in an efficient
manner.
[0053] Further, the attachment of articles at different locations
on the wicketed bags can be particularly advantageous for
customized delivery of wicketed bags to different distributors and
other users. For example, one type of article, such as advertising
literature, may be better positioned on the wicketed bag by
placement in either an upper or lower location on the outer
surface. Further, where the pre-packaged articles are objects such
as promotional items, it may be advantageous to locate the
promotional item at a particular place on the outer surface of the
wicketed bag.
[0054] Those skilled in the art will recognize that a process
carried out in accordance with the various embodiments of the
invention can be used to fabricate wicketed bags that alternatively
contain different pre-packaged articles and non-packaged articles.
For example, first group of wicketed bags 134 can be fabricated to
include objects within the external compartment, while second group
of wicketed bags 136 can be fabricated to include written materials
in the external compartment. Further, more than one article can be
inserted in the external compartment.
[0055] Thus, it is apparent that there has been described a
wicketed bag fabrication and packaging process that provides the
advantages set forth above. Although the invention has been
described and illustrated with reference to specific illustrative
embodiments thereof, it is not intended that the invention be
limited to those illustrative embodiments. Those skilled in the art
will recognize that variations and modifications can be made
without departing from the spirit of the invention. For example,
various packaging materials can be used to fabricate the wicketed
bags and the external compartments. For example, rather than
plastic materials, paper materials can be used. It is, therefore,
intended to include within the invention all such variations and
modifications that fall within the scope of the appended claims and
equivalence thereof.
