Description:
FIELD  
         [0001]    The disclosure herein is directed generally to materials for forming carton blanks and methods of forming carton blanks from such materials.  
         BACKGROUND  
         [0002]    Once, primarily used to package the aggressive surfactants of concentrated detergents, laminate film packaging is now used for numerous applications including: soap boxes, cereal boxes, bottle carriers, can boxes, etc.  
           [0003]    The components of laminate film packaging generally include a layer of printed film and a layer of paperboard. The paperboard serves as a substrate to which the film layer is laminated. Film provides strength to the composition, therefore allowing for thinner, recycled, or otherwise lower strength paperboard to be used. Laminate film packaging is environmentally sound because in many situations it is made from post-consumer recycled fibers and is itself recyclable. Products packaged in laminate film packaging may have lower contamination levels due to the barrier properties of the film, resulting in products staying fresher longer and reaching the end-user in better condition.  
           [0004]    Laminate film packaging is often made from recycled materials. In many cases, the paperboard is a Double-Kraft Lined (DKL) product. DKL paperboard consists of mixed fibers in the inner plies with one ply of Kraft on either side for strength.  
           [0005]    Typically, the film used for laminate film packaging is polyethylene (PE), polypropylene (PP), or polyethylene terephthalate (PET). The film may optionally be provided with a unique visual characteristic such as a holographic or mearl pattern. The film may be surface printed or reverse printed with graphics. The film improves the aesthetics while adding extra strength to the paperboard.  
           [0006]    An optional metalization layer deposited on the laminate film may further improve aesthetics of the laminate film package. The optional metalization layer may be included to provide a barrier layer for improved graphics. The improved graphics is a result of the reflectivity of the metalization layer. The metalization layer may be provided on a surface of the film by vapor deposition and is commonly an aluminum layer.  
           [0007]    The term ‘web’ is commonly used in the packaging industry to refer to a large roll of material to which various processes (e.g. printing and surface treatments, cutting, scoring, etc.) are provided. One such process is the cutting of blanks from the web of material.  
           [0008]    After separating blanks from the web of material, the blanks may be inserted into a separate machine or inline section of a continuous machine for gluing and folding (often referred to as a folder/gluer machine). Gluing and folding is often completed while the package is moving at a somewhat relatively high speed in a progressive, continuous manner.  
           [0009]    While traveling through the folder/gluer machine, adhesive is used to erect packages from the laminate film carton blanks. Two types of adhesive are conventionally used. The first type of adhesive is cold glue and the second type is hot glue.  
           [0010]    Cold glue is typically in the form of an adhesive dissolved in a volatile carrier. The cold glue is generally applied to the laminate film packaging in a wet condition. Upon assembling the packaging, the volatile carrier is wicked from the adhesive into the paperboard or evaporated. The resulting dry adhesive provides tack to attach one section of the packaging to another. Since the volatile carrier needs to be removed from the cold glue, cold glue typically works better on plain paperboard (i.e. without film). The cold glue works sufficiently well when attaching laminate film packaging where a paperboard-to-paperboard attachment is required. Additionally, the packaging may be assembled with cold glue having a film-to-paperboard attachment. It is difficult, however, to obtain a satisfactory film-to-film attachment using cold glue due to the required removal of the volatile carrier. Cold glue may be dispensed from a nozzle or a cold glue pot. The nozzle for cold glue is often controlled by a solenoid that is actuated by a control system. The cold glue pot is a pad-printing device wherein a rotating pad has a raised area. The raised area picks-up glue from the glue pot and transfers it to the packaging.  
           [0011]    Hot glue is an adhesive that is semi-fluid when hot and semi-solid when cold. The hot glue is applied hot to packaging. Before the hot glue cools, the packaging is assembled. The hot glue is then cooled to provide an attachment between the two parts of the package. The hot glue provides a sufficient bond on film-to-film applications as well as paperboard-to-film and paperboard-to-paperboard attachment. Hot glue is most commonly dispensed from a nozzle. The nozzle is typically actuated by a solenoid that is controlled by a control system.

     DESCRIPTION  
       [0028]    Described herein is a web of material, apparatus for making the web of material and a method for producing blanks for containers from the web of material. The apparatus and method may be utilized for any one of a plurality of containers (e.g., consumer packaging, shipping packaging, point-of-purchase display packaging, etc). One such container is a bottle carrier (e.g.  90 , FIG. 1) used to carry bottles. The description herein is directed to the exemplary bottle carrier. It is noted, however, that this description is for descriptive purposes only. It is further noted that the present apparatus and method may be adapted to be utilized for any one of a number of containers as appreciated by those skilled in the art.  
         [0029]    As previously mentioned, one exemplary container manufactured with the present apparatus and method is a bottle carrier  90  shown in FIG. 1. With reference to FIG. 2, the bottle carrier  90  may be manufactured from a blank  100  and a bottom portion  200  (FIG. 3). The blank  100  may be provided with a plurality of panels and fold lines. The blank  100  may be provided with a front panel  102 , a right front panel  104 , a left front panel  106 , a front partition carrier panel  108 , a first front partition  110  and a second front partition  112 . The blank  100  may be further provided with a back panel  122 , a right back panel  124 , a left back panel  126 , a back partition carrier panel  128 , a first back partition  130  and a second back partition  132 . The blank  100  may be further provided with a plurality of glue flaps such as a right front glue flap  140 , a first front partition glue flap  142 , a second front partition glue flap  144 , a right back glue flap  146 , a first back partition glue flap  148 , a second front partition glue flap  150 . The blank  100  may be further provided with a plurality of fold lines such as fold lines  160 ,  162 ,  164 ,  166 ,  168 ,  170 ,  172  and  174 . It is noted that the fold lines identified above are not an exhaustive list. These fold lines are specifically identified for descriptive purposes only and it is noted that additional fold lines may exist as shown, for example, in the figures. The blank  100  may be further provided with a printed film portion  180  (as shown in FIG. 2 as a shaded area) and a plurality of paperboard portions such as exposed paperboard portions  182 ,  184 . The term ‘exposed paperboard portions’ is herein defined as areas of paperboard that are not covered by film. The particular attributes of the film portion  180  and the paperboard portions  182 ,  184  will be discussed later herein; however, in brief, the portions  180 ,  182 ,  184  are provided for reasons of adhesion requirements during the conversion from the blank  100  to the bottle carrier  90  (FIG. 1).  
         [0030]    As shown in FIG. 1, the bottle carrier  90  may be provided with a bottom portion  200 . The bottom portion  200  is provided with a plurality of panels and fold lines. With reference to FIG. 3, the bottom portion  200  may be provided with a front bottom panel  202  and a back bottom panel  204 . The bottom portion  200  may be further provided with a plurality of glue flaps such as a front glue portion  206  and a back glue portion  208 . Additionally, the bottom portion  200  may be provided with a printed film portion (not shown) or simply be plain paperboard, depending on the desired cosmetic appearance or the desired mechanical properties of the bottle carrier  90 .  
         [0031]    The process of manufacturing and assembling a variety of containers, is discussed, for example, in the following: U.S. patent application Ser. No. 09/864,567 for a CARTON BLANK AND METHOD OF FORMING A CARTON of Joseph C. Walsh filed on May 24, 2001 and U.S. patent application Ser. No. 09/877,336 for a TRANSFER GLUE SYSTEM AND METHOD FOR A RIGHT ANGLE GLUING MACHINE of Joseph C. Walsh et al. filed on Jun. 8, 2001; both of which are hereby specifically incorporated by reference for all that is taught and contained therein.  
         [0032]    The bottle carrier  90  may be manufactured by a variety of methods. One such method may be utilization of a web processing center  400  (FIGS. 4 and 5) and a folder/gluer machine (not shown). By utilizing the web processing center  400  and the folder/gluer machine, the bottle carrier  90  may be manufactured by making the blank  100  and the bottom portion  200 , and erecting the blank  100  and bottom portion  200 . The process of making the blank  100  and the bottom portion  200  will now be described.  
         [0033]    The blank  100  and the bottom portion  200  may be manufactured by a web processing center. One exemlary web processing center  400  is shown schematically in FIGS. 4 and 5. FIGS. 4 and 5 show the web processing center  400  in a schematic side elevation view and a schematic bottom plan view, respectively. The web processing center  400  receives raw materials, such as paperboard, film, adhesive and ink, and converts the raw materials into blanks  100  and bottom portions  200 . Additionally and with respect to FIG. 4, the web processing center  400  may generally define an upstream portion  500  and a downstream portion  506 . The downstream portion  506  is located in a downstream direction  504  from the upstream portion  500 . The downstream direction  504  generally refers to the flow of material in the web processing center  400 . The upstream portion  500  is located in an upstream direction  502  from the downstream portion  506 . Therefore, the upstream direction  502  is oppositely disposed from the downstream direction  504 .  
         [0034]    With further reference to FIG. 4, the web processing center  400  may be provided with a roll  402  of a relatively rigid material mounted so that a continuous strip  422  may be removed therefrom. The roll  402  and continuous strip  422  of relatively rigid material may be hereinafter also referred to as the relatively rigid material  402 ,  422 . The roll  402  and the continuous strip  422  of relatively rigid material may be any one of a variety of rigid materials, for example a paperboard material such as 0.021 inch single or Double-Kraft lined (DKL) recycled or natural Kraft board. The roll  402  and the continuous strip  422  of relatively rigid material have a rigid material first edge  424  and an oppositely disposed rigid material second edge  426  (FIG. 5). The rigid material first and second edges  424 ,  426  define a rigid material width “WR” (FIG. 5) externally therebetween. The relatively rigid material  422  may be fed between a driven gravure roll  434  and an idler pressure applying roll  436 . A supply tank  430  may be mounted at a fixed location and may contain a supply of a suitable adhesive material  438 . Suitable adhesive materials may be any one of a variety of adhesives capable of being applied to the relatively rigid material  422  and thereafter bonding other materials to the relatively rigid material  422 . Suitable adhesive materials  438  include, but are not limited to, hot adhesives (e.g. polyethylene, ethyl vinyl acetate (EVA), etc.) and cold adhesives (e.g. starch adhesives, liquid adhesives, etc.). A transfer roll  432  may be rotatably mounted to pass through the adhesive material  438  and then to any number of raised surfaces such as raised surfaces  440 ,  441  of the gravure roll  434  to coat the raised surfaces  440 ,  441  with the adhesive material  438 . Although the gravure roll  434  is shown in this exemplary embodiment, it is understood that other types of conventional laminating apparatus may be used to apply the adhesive material  438  to the continuous strip of relatively rigid material  422 . Other alternative methods for adhering film to paperboard include flexographic printing and radiation cure products (e.g. ultraviolet curable adhesives, electron beam adhesives, etc.)  
         [0035]    The web processing center  400  may be further provided with a roll  406  of a relatively fluid impervious material so that a continuous strip  450  may be removed therefrom. The roll  406  and continuous strip  450  of relatively fluid impervious material may hereinafter also be referred to as relatively fluid impervious material  406 ,  450 . The roll  406  and continuous strip  450  of relatively fluid impervious material may be any one of a number of materials capable of providing a barrier from one side to another side thereof. Examples of relatively fluid impervious materials  406 ,  450  include, but are not limited to, polyethylene, polypropylene, polyester, or other polymer equivalents having somewhat fluid impervious properties. Additionally, the roll  406  and the continuous strip  450  of relatively fluid impervious material have a fluid impervious material first edge  454  and an oppositely disposed fluid impervious material second edge  456  (FIG. 5). The fluid impervious material first and second edges  454 ,  456  define a fluid impervious material width “WF” (FIG. 5) extending therebetween. The relatively fluid impervious material  450  may be adhesively attached to the relatively rigid material  422  by the adhesive material  438 . The assembly of the relatively rigid material  422  and the relatively fluid impervious material  450  may be referred to as an assembled web  470 . The adhesion may be promoted by a pair of idler pressure applying rolls  458 ,  460 . The idler pressure applying rolls  458 ,  460  press the relatively fluid impervious material  450  against the adhesive material  438  disposed on the relatively rigid material  422 , thereby adhesively joining the relatively fluid impervious material  450  to the relatively rigid material  422 .  
         [0036]    The web processing center  400  may be further provided with a printing center  408 . The printing center  408  is shown in FIG. 4 as printing on an external side  464  of the relatively fluid impervious material  450 . In an alternative configuration, the printing center  408  may print on an internal side  466  of the relatively fluid impervious material  450  by placing the printing center before the idle rollers  458 ,  460 .  
         [0037]    The web processing center  400  may be further provided with a film stripping center  480 . The film stripping center  480  may remove various sections (e.g. detached portion  490 ) of the relatively fluid impervious material  450  from the assembled web  470 . In order to remove a section of the relatively fluid impervious material  450 , it is preferred that sections to be removed (e.g. detached portion  490 ) not be adhesively attached to the relatively rigid material  422 . For this purpose, the raised surfaces (e.g.,  440 ,  441 ) or the gravure roll  434  may be located only in selected areas so that adhesive is not applied to at least one predetermined portion of the relatively rigid material  422 . The film stripping center  480  may be provided with any one of a variety of film cutters such as a rotary knife  482 . The rotary knife  482  may be provided with a plurality of knives such as a first knife  484  and a second knife  486 ; the knives  484 ,  486  being provided to separate a portion of detached film  490  from the relatively fluid impervious material  450  which is a subcomponent of the assembled web  470 . The film stripping center  480  may be further provided with a collection center  492  provided for receiving the detached film  490 . The detached film  490  that is collected in the collection center  492  may be discarded or recycled.  
         [0038]    The web processing center  400  may be further provided with a blanking center  410 . Alternatively, the blanking center  410  may be separate from the web processing center  400 , whereby a web of material (e.g.  470 ) is transported (commonly in a roll) from the web processing center  400  to the blanking center  410 . The blanking center  410  may be any one of a variety of cutting centers known in the art. One such blanking center  410  may include a rotary cutter (not shown). The rotary cutter ‘rolls’ with the assembled web  470 ; as the rotary cutter rolls, knives provided on the rotary cutter penetrate the assembled web  470  and separate various portions thereof. Such portions separated from the assembled web may include the blank  100  and the bottom portion  200 .  
         [0039]    After making the blank  100  and the bottom portion  200  in the web processing center  400 , the blank  100  and bottom portion  200  are introduced into the folder/gluer machine (not shown). The folder/gluer machine is utilized for folding and gluing the blank  100  and the bottom portion  200  to erect the bottle carrier  90  (FIG. 1). Folding and gluing of the present exemplary package may, for example, be substantially similar to the process described in U.S. patent application Ser. No. 09/877,336 for a TRANSFER GLUE SYSTEM AND METHOD FOR A RIGHT ANGLE GLUING MACHINE of Joseph C. Walsh et al. filed on Jun. 8, 2001, as previously referenced.  
         [0040]    An exemplary process of manufacturing the blank  100  will now be detailed. Prior to running the web processing center  400 , container blanks are designed and nested. Nesting blanks on a web may be controlled by a number of requirements. One such requirement may be the maximization of material usage. Another requirement may be the location of features within the web for processing concerns. Blanks may have surfaces that require film and graphics printed thereon; these film and graphics surfaces may comprise less area than the entire area of the blank. As such, the opportunity exists to nest and process blanks such that film and graphics are applied to only areas which require the film and graphics. Areas that may require film and graphics are areas that are visible in an as-erected state (e.g., bottle carrier  90 ). Additionally, blanks may be oriented such that areas that are attached with adhesive to each other in the folder/gluer machine may remain uncoated by film, thereby promoting adhesion between two surfaces. This adhesion promotion between two surfaces has been previously discussed in the background section; however, in brief, adhesion between two paperboard surfaces with cold glue is preferable over adhesion between relatively rigid material such as paperboard and relatively fluid impervious material such as film with cold glue.  
         [0041]    Having provided a description of the nesting of blanks on the assembled web  470 , a description of the process of manufacturing the assembled web  470  will be provided herein. As shown in FIG. 10, a plurality of blanks such as blank  100  (detailed in FIG. 2) may be nested on the assembled web  470  of material. The assembled web  470  in the present description includes the relatively rigid material  422  and the relatively fluid impervious material  450 . The blanks  100  may be nested to minimize the amount of detached film  490  (FIG. 4).  
         [0042]    It is noted that cross-sectional elevations views in the drawings (e.g., FIGS. 7, 9 and  11 ) show materials with exaggerated thickness. Such exaggeration is provided for clarity of description. In general, the thickness of materials is less than portrayed in the drawings.  
         [0043]    With reference to FIG. 4, at the upstream portion  500  of the web processing center  400 , the continuous strip of relatively rigid material  422  may be provided from the roll  420 . The continuous strip travels down the length of the web processing center  400  in the downstream direction  504 , driven by any of a variety of mechanisms well known in the art. The relatively rigid material  422  may receive adhesive from the gravure roll  434 . In the present exemplary application, two strips of adhesive material  438  (FIG. 4) may be applied by the two raised surfaces  440 ,  441  (FIG. 5) as shown in FIGS. 6 and 7. With reference to FIG. 6, the first strip of adhesive material may hereinafter be referred to as a first adhesive strip  530 . The second strip of adhesive material may hereinafter be referred to as a second adhesive strip  540 . The first adhesive strip  530  may be provided having a first edge  532  and an oppositely disposed second edge  534 . The second adhesive strip  540  may be provided having a first edge  542  and an oppositely disposed second edge  544 . The edges  532 ,  534 ,  542  and  544  correspond to edges of the raised surfaces  440 ,  441  of the gravure roll  434  (FIG. 5). The first and second adhesive strips  530 ,  540  travel with the relatively rigid material  422  in the downstream direction  504 .  
         [0044]    With reference again to FIG. 4, the relatively rigid material  422  having the adhesive strips  530 ,  540  applied thereto travels to the location of the relatively fluid impervious material  450 . The continuous strip of relatively fluid impervious material  450  may be adhesively attached to the relatively rigid material  422  by the adhesive strips  530 ,  540 . As best shown in FIG. 8, in the particular embodiment shown, the width of the relatively fluid impervious material  450  (denoted by “WF”) may result in alignment of the fluid impervious material first edge  456  with the first adhesive strip first edge  532 . Additionally, the width of the relatively fluid impervious material  450  may also result in alignment of the fluid impervious material second edge  454  with the second adhesive strip second edge  544 . Such configuration further results in a film central portion  550  of the relatively fluid impervious material  450  being adjacent to a web central portion  552  of the relatively rigid material  422 . The film and web central portions  550 ,  552  may reside between the first adhesive strip second edge  534  and the second adhesive strip first edge  542 . As previously mentioned and with reference to FIG. 4, the idler pressure applying rolls  458 ,  460  promote the bonding of the relatively fluid impervious material  450  to the relatively rigid material  422  thereby rendering the assembled web  470 .  
         [0045]    The assembled web  470  may be further presented to the printing center  408  for receiving graphics. As previously mentioned, the printing center  408  may be located at any of a variety of locations within the web processing center  400  depending on the surface of the assembled web  470  to be printed.  
         [0046]    With further reference to FIG. 4, the detached film  490  may be removed from the assembled web  470  at the film stripping center  480 . As previously described, a cutter such as the rotary knife  482  may make a first cut  560  and a second cut  562  in the relatively fluid impervious material  450 . With reference to FIGS. 11 and 12, in the exemplary embodiment shown, the first cut  560  may be aligned with the first adhesive strip second edge  534  and the second cut  562  may be aligned with the second adhesive strip first edge  542 . The detached film  490  may be removed from the assembled web  470  and recycled or discarded as previously described.  
         [0047]    With reference to FIG. 10, upon removing the detached film  490  (FIG. 4), two strips of the relatively fluid impervious material  450  remain. One strip of the relatively fluid impervious material  450  will hereinafter be referred to as a first film strip  600  and the second strip will hereinafter be referred to as a second film strip  610 . The first film strip  600  has a first edge  602  and an oppositely disposed second edge  604 . The second film strip  610  has a first edge  612  and an oppositely disposed second edge  614 . In the present exemplary application, the first film first edge  602  may be the same as the relatively fluid impervious first edge  456 , the first film second edge  604  may be the same as the first cut  560 , the second film first edge  612  may be the same as the second cut  562  and the second film second edge  614  may be the same as the relatively fluid impervious second edge  454 .  
         [0048]    With reference to FIG. 5, after removing the detached film  490  (FIG. 4), the assembled web  450  may be presented to the blanking center  410 . As previously described, the blanking center  410  may be utilized to remove individual blanks such as blank  100  from the assembled web  450 . Blank  100  is best shown in FIG. 2, wherein the film strip (e.g.,  600 ,  610 ) is shown as a shaded region. Additionally, FIG. 2 shows unshaded regions that are exposed paperboard portions.  
         [0049]    The previous description of producing blanks  100  with the web processing center  400  may yield a plurality of blank  100  (FIG. 2). With particular reference to FIG. 2, the previously mentioned printed film portion  180  may be either the first film strip  600  or the second film strip  610  depending on the side of the assembled web  470  from which the blank  100  was produced. The paperboard portion  182  may be derived from the web center portion  552 . The paperboard portion  184  may be derived from a portion of material near either the first or second edge  424 ,  426  the relatively rigid material  422 .  
         [0050]    By utilizing this apparatus and method, blanks may be manufactured having certain portions thereof covered with film and other portions thereof not covered with film. Such blanks (and the containers formed therefrom) are advantageous for several reasons. One advantage may be to minimize the usage of the relatively fluid impervious material. The minimization of the relatively fluid impervious material may decrease the cost of raw materials for the containers (i.e., decreasing manufacturing cost). Another advantage may be the ability to use cold glue in the folder/gluer machine. Because exposed paperboard portions (e.g.,  182 ,  184  in FIG. 2) remain uncovered by film, cold glue may be used to erect the container. Such usage of cold glue has been previously discussed; however in review, it may be preferred to use cold glue on exposed paperboard portions (e.g.,  182 ,  184  in FIG. 2) rather than on film portions (e.g.,  180  in FIG. 2). The use of cold glue in the folder/gluer machine may increase the speed at which containers may be manufactured because cold glue may be applied faster than hot glue. Increases of speed in the folder/gluer machine may result in increased efficiency, which results in increased profitability.  
         [0051]    While illustrative and presently preferred embodiments of the invention have been described in detail herein, it is to be understood that the inventive concepts may be otherwise variously embodied and employed, and that the appended claims are intended to be construed to include such variations, except as limited by the prior art.
