Title: Multiple-container composite package

Description:
CROSS REFERENCE TO RELATED APPLICATIONS 
     The present application is a National Stage of International Application No. PCT/EP2016/066922, filed on Jul. 15, 2016, which claims priority to European Patent Application No. 15177379.3, filed on Jul. 17, 2015, the entire contents of which are being incorporated herein by reference. 
     FIELD OF THE INVENTION 
     The present invention concerns a composite package comprising a plurality of primary packages. 
     BACKGROUND OF THE INVENTION 
     It is well known to provide a number of different consumer products in the form of multiple-container packages, or “composite packages,” wherein a quantity of individual containers are bundled together within an exterior packaging to form a single bundled package. 
     The individual containers are generally of an enclosed or sealed type, so as to maintain the quality of the product within; while the exterior packaging is configured to hold the individual containers together during storage and transport while at the same time being easily opened by the end user. 
     Such composite packages have been employed in many industries, but are particularly well-known in the food and beverage domain, where it is often desirable from a consumer perspective to purchase large quantities of certain products at once, but where the use of a single large container (e.g. a 5-liter bottle of mineral water) is disfavoured because of inconvenient handling or product degradation after opening. A single large container may also be more difficult to use than an equivalent volume of smaller products, particularly where a liquid product that is dispensed by pouring is involved. 
     These composite packages are advantageous in that they are generally easier to purchase and store than an equivalent amount of product in bulk form, in a single large container, or in a number of smaller containers purchased individually. Additionally, the exterior packaging may be assigned a unique UPC barcode or price tag, facilitating purchase and inventory. 
     Since a large number of containers are bundled together into one composite package, the resulting composite package may be quite bulky and difficult to carry in one hand. To this end, means such as handles are generally provided, to facilitate the manipulation and transport of the composite package. 
     However, these composite packages can be nonetheless uncomfortable and fatiguing to carry in one hand, as composite packages enclosing a large number of containers can be heavy and unwieldy to carry. Such heavy packages can also create a high degree of muscle and joint strain in the user; for instance, particularly bulky composite packages tend to force the user to carry them with his/her arms slightly extended from the body, which forces a pronation of the wrists and strains unnecessarily the arm and wrist muscles. Likewise, carrying a large, heavy package in one hand can make it difficult for the user to maintain equilibrium; such an unbalanced load may, over time, lead to back pain or other orthopaedic ailments in the user. 
     In the composite packages known in the art, one means of remedying this is to break open the package and remove the individual containers within. However, by doing so, the advantages of having a single composite package with a handle are lost. 
     Alternately, it is known to provide composite packages which only contain 2 or 4 of the individual containers. However, such an arrangement is not satisfactory, in that in order to yield a composite package with a sufficient volume of product, the individual packages must themselves be rather large and unwieldy. There is thus a need to provide a composite package which resolves at least some of the disadvantages discussed above. 
     SUMMARY OF THE INVENTION 
     Accordingly, there is provided a composite package comprising a plurality of primary packages and a handle attached at two extremities thereof to said composite package. 
     According to the invention, the plurality of primary packages are gathered into a plurality of secondary packages each containing at least one of said primary packages, said handle having at least one separation line extending along the length thereof and dividing said handle into a plurality of sub-handles each attached at the extremities thereof to one of the secondary packages such that when one of said plurality of secondary packages is extracted from the composite package, said handle is torn along said at least one separation line, the sub-handle attached to said one of said plurality of secondary packages being retained therewith. 
     A composite package so configured is advantageous in that when the user splits the handle along the at least one pre-cutting line to separate one or more of the secondary packages from the composite package, the secondary packages remain intact, while separating the handle in such a way that each of the secondary packages has a sub-handle attached to it. The consumer may then use the sub-handle to carry and manipulate the secondary package in the same way as the handle is used to carry and manipulate the composite package. 
     In this way, the single, large composite package is divided into two or more smaller secondary packages. The secondary packages are of a lesser weight and smaller size than the composite package. At the same time, the retention of the sub-handles on each of the secondary packages ensures that the secondary packages can be easily manipulated and transported. 
     Thus, the flexibility and user-friendliness of the composite package is maximized. 
     In a possible embodiment, at each extremity of the handle there is provided an attachment region comprising a plurality of strips extending from said extremity of said handle at an attachment angle relative to the extension of the centreline of said handle, each of said strips attaching one of the sub-handles to one of the secondary packages. 
     This is advantageous in that the strips, disposed at the attachment angle, will position the secondary package in the most ergonomically-correct position possible when the secondary package is extracted from the composite package and held by its sub-handle. 
     Specifically, the angled application of the strips will counteract any off-centre positioning of the centre of gravity of the secondary package that occurs when said secondary package is extracted from the composite package. 
     In this way, excessive pronation of the user&#39;s hand when lifting the secondary package by its sub-handle is avoided. The composite package is thereby rendered more comfortable and efficient to use. 
     Preferably, the width of each of the plurality of strips is substantially equal to the width of the corresponding sub-handle. 
     This is advantageous in that the strength of the attachment between the handle and the composite package is maximized while minimizing the concentration of tensile stresses that might otherwise occur in the handle due to the discontinuity in width at the interface of the strip and the sub-handle. 
     In a possible embodiment, each attachment region is constituted by a single adhesive tape, said adhesive tape being cut over the portion thereof extending from the extremity of the handle, thereby constituting the plurality of strips. 
     This is advantageous in that the single adhesive tape will maximize the strength of the handle-package joint, thereby maximizing the size of composite package that may be achieved. 
     In another possible embodiment, each attachment region is constituted by a plurality of adhesive tapes each extending from said extremity. 
     This is advantageous in that a plurality of strips is most efficient to apply, in that depending on the width of the sub-handles, the plurality of strips may be all furnished in the same length and width, and in any event require no cutting or manipulation to apply to the handle and composite package. 
     Preferably, the attachment angle is between 10° and 60°. 
     Most preferably, the attachment angle is between 10° and 30°. 
     This is advantageous in that it will result in the most stable and comfortable distribution of the weight of the secondary package when it is separated from the composite package and carried by the sub-handle. This will, in turn, reduce fatigue and discomfort for the person carrying the secondary package so separated. 
     Preferably, the width of the handle at each of the two extremities thereof is between 10 millimeters and 80 millimeters. 
     Most preferably, the width of the handle at each of the two extremities thereof is between 40 millimeters and 60 millimeters. 
     Such widths are optimal for the dimensions and weights most frequently encountered in composite packages for consumer products. 
     In a possible embodiment, the handle has a reduced width at a central region of said handle. 
     This is advantageous in that when the primary containers are bottles, the handle will be naturally induced to lie between the two secondary packages when the composite package is lifted. 
     In a possible embodiment, each of the sub-handles has a substantially equal width. 
     In this way, the fabrication of the handle, as well as the positioning and attachment of the adhesive tape(s) is simplified. 
     Preferably, the handle is oriented parallel with or perpendicular to a longitudinal dimension of the composite package. 
     This is advantageous in that, when the secondary packages are extracted from the composite package and carried by the user in an arms-down position, the primary containers within the secondary packages are carried as closely to the body as possible. 
     In this way, joint and muscle strain on the user&#39;s hands and arms are minimized, reducing fatigue and improving the ergonomics of the composite package. 
     Preferably, the separation line comprises at least one pre-cutting line extending over the entire length of said separation line. 
     This is advantageous in that as the pre-cutting line is broken, the separation of the sub-handles is performed in a simple and precise manner. Such a configuration avoids the inherent difficulty of creating a straight free-hand tear in a non-perforated material. The strength and integrity of the sub-handles is thereby preserved, maximizing the usability of the composite package. 
     Alternatively, the at least one separation line comprises a pre-cutting extending over a part of the length of said at least one separation line, said at least one separation line remaining un-perforated at the extremities of the handle. 
     This is advantageous in that the extremities of the handle maintain their maximum strength, thereby maximizing the weight of the composite package and increasing its resistance to inadvertent separation of the secondary packages comprised within. 
     In a preferable embodiment, at least one of the secondary packages comprises a plurality of primary packages disposed in a linear or close-packed arrangement. 
     This is advantageous in that such arrangements facilitate the fabrication, transport, storage, and use of the composite package. 
     A linear arrangement is particularly advantageous in that, as the linear arrangement aligns the primary packages within the secondary packages along a grid, the resulting secondary packages and composite package have a substantially rectangular footprint and parallelpipedal form; this tends to facilitate the stocking, transport, and storage of the packages in warehouses, store shelves, etc. which are generally adapted to rectilinear packages. 
     Alternately, the close-packed arrangement of the primary packages will maintain a maximum of stability and structural strength in the secondary package once it is separated from the composite package. Close-packed arrangements also tend to realize the best possible packing ratio, containing the greatest possible volume of product within a given volume.

     DETAILED DESCRIPTION OF THE INVENTION 
       FIG. 1  illustrates a composite package  100  according to a first embodiment of the invention. The composite package  100  comprises two secondary packages  102   a  and  102   b , each of which comprises three primary packages  104 . 
     The primary packages  104  are packages of a product of a size that would be appropriate for individual purchase and consumption; the inclusion of several of the primary packages  104  into the composite package is therefore done to facilitate the purchase of several primary packages at once, as described above. It will be understood, then, that the size and number of the primary packages  104  is therefore a function of the product contained therein, and may vary from what is depicted here. 
     Within each of the secondary packages  102   a ,  102   b , the primary packages are grouped together and bound by a band  106 . The two bands  106  serve to hold the primary packages  104  in position relative to each other, and give the secondary packages  102   a ,  102   b  a degree of structural strength and rigidity. 
     It will be noted that in other implementations of the invention, the band may be supplemented or replaced by other means such as plastic strapping, shrink-wrapping, or the like, as appropriate to the particular application in question. 
     The composite package  100  is further provided with a handle  108 . The handle  108  is attached to the secondary packages  102   a ,  102   b  at its two extremities  110 , of which one is visible here. The means for connecting the handle  108  to the secondary packages  102   a ,  102   b  is discussed in further detail below. 
     The handle  108  is provided with a pre-cut separation between the secondary packages  102   a ,  102   b , in the form of a separation line  112  which lies along the centreline of the handle  110  and divides it into sub-handles  114   a ,  114   b . The width of the handle  108  is generally chosen so as to correspond to the total weight of the primary packages  104  within the composite package  100 ; generally speaking, however, it will be between 10 and 80 mm, and most frequently between 40 and 60 mm, as these are the dimensions which fit most comfortably in the human hand. 
     It will be noticed that the sub-handles  114   a ,  114   b  are here of a substantially equal width. This is because the two secondary packages  102   a ,  102   b  contain equal amounts of product within the primary packages  104 . 
     As a general rule, it is desirable to provide a wider handle for a heavier load: this may implicate forming the handle from a longer, thicker, and/or wider tape, providing a localized region of increased width and/or thickness, or some combination thereof. Moreover, the dimensions of each sub-handle  114  should ideally reflect the proportion between the total weight of the product within its respective secondary package  102  and the total weight of product in the entire composite package  100 . 
     Of course, the person of ordinary skill in the art will be able to determine the optimal width for each of the sub-handles in any specific application. 
     It should also be noted that, in this embodiment, the perforation line  112  extends substantially over the entire length of the handle. However, the perforation line  112  does not extend right to the edge of the handle  108 . This is so that the perforation line  112  does not tear prematurely as a result of the forces exerted upon the composite package  100  during normal handling. 
     The fabrication of the handle  108  will now be discussed. 
     The handle  108  is, in this embodiment, fabricated from a single length of material having a width substantially equal to that of the handle  108  where it attaches to the secondary package  102   a ,  102   b  at the extremities  110 . The adhesive tape is preferably pre-cut so as to form the reduced width over the majority of the length of the handle  108  that is particularly apparent in  FIG. 1 . 
     The handle can be fabricated in a number of different configurations and materials. For instance, the handle may be fabricated from a simple elongate piece of flat material, such as paper- or cardboard, plastic or foam material, or other materials as appropriate. 
     By way of example, in this embodiment the handle  108  is fabricated from a piece of adhesive plastic tape. In order to allow having a gripping portion (not sticky), a gripping member (not represented) in the form of a flat member of moderate rigidity is positioned over a portion of the length of the handle on the adhesive side of the handle. The remaining adhesive portions over the length of the handle are located at the extremities  110  of the handle and are attached to the secondary package  102   a ,  102   b . Such a configuration is advantageous in that such tapes can be easily produced and manipulated in high-speed, continuous manufacturing environments. However, other configurations are certainly possible. 
     It may also be desired to provide reinforcement to the handle. This will be discussed in further detail below with reference to  FIG. 6 . 
     With reference to  FIGS. 1 and 2 , it is seen that the handle  108  is oriented to extend along a longitudinal direction of the composite package  100 ; that is, parallel with the longest dimension of the composite package  100 . The effect of this is apparent in  FIG. 2 , where a user  200  carries the composite package  100  with the handle substantially parallel to said user  200 &#39;s sagittal plane (i.e. the plane passing vertically through the spinal column and solar plexus). Such an orientation is more comfortable for the bones and musculature of the arm  202  and wrist  204  of the user  200 , in that it results in the least amount of strain when the composite package  100  is of a moderate to heavy weight. Most notably, pronation and flexion of the wrist  204  is reduced, relative to those multi-container packages known in the art wherein a handle is disposed transversally. 
     It will also be noted that the handle  108  is of a reduced width at a central region  116  relative to the extremities  110 . This is advantageous in that the diminished width enables the handle to slip between the primary containers  106  when the composite package is lifted by the handle  108 . Moreover, the increased width at the extremities  110  facilitates the attachment of the handle  108  to the secondary packages  102   a ,  102   b.    
     Of course, it may in other embodiments be preferable to furnish the handle as a strip of uniform width. This will minimize manufacturing costs as such a configuration eliminates the need to cut or otherwise shape the handle. 
     Turning now to  FIG. 3 , the composite package  100  is shown with the handle  108  partially separated into the two sub-handles  114   a ,  114   b.    
     In particular, it can be seen that the pre-cutting along the separation line  112  has been completely torn open, and only the un-perforated parts of the handle  108  at the extremities  110  remain intact. 
     When the user  200  further separates the secondary packages  102   a ,  102   b , the extremities  110  will separate along the un-perforated portion  300  of the separation line  112 . This is because the tearing of the pre-cutting along the separation line  112  naturally creates a preference in the material of the handle  108  for further tearing in the same direction. 
     Of course, depending on the material and construction of the handle, this may not be sufficient in all conceivable applications to ensure a clean, even separation of the sub-handles. It should therefore be understood that, in other embodiments of the invention, the pre-cutting of the separation lines may extend over the entire length of the handle, right up to the ends of the extremities. 
     In such a case, it will be understood that, despite the presence of the precut over substantially the entire length of the handle, the handle will remain intact, without a precut, at the very edge thereof, so as to avoid any inadvertent tearing of the handle. 
     Alternately, other means of controlling the separation of the sub-handles (e.g a crease) may be envisioned to induce a clean, even tear in the handle material. The exact configuration will depend on the particular implementation in question. 
     The pre-cutting can be formed by any conventional means, for instance mechanical cutting or laser cutting or burning. Laser cutting may be particularly advantageous in embodiments such as the one depicted here, in that since the pre-cutting may be easily interrupted by controlling the laser; in this way the un-perforated region at the extremities  110  of the handle  108  are easily produced. This may be particularly advantageous in high-speed, high-volume production operations. 
     It should be noted that a handle as according to the present is particularly advantageous, in that it provides an excellent degree of flexibility in how it can be fabricated and implemented during package fabrication. For instance, in one possible implementation the handles may be fabricated from a flat sheet of a plastic membrane, which is coated with an adhesive, given a paper backing and subsequently die-cut to separate individual, pre-cut handles therefrom. In another possible embodiment the handles are formed in a continuous process, such that the handles are cut from the tape, pre-cut to form the sub-handles, and attached to composite packages. The particular manufacturing implementation can be tailored as appropriate to the composite packages in question and the rate at which they are to be produced. 
       FIG. 4  depicts the user  200  carrying the two secondary packages  102   a ,  102   b . The two secondary packages  102   a ,  102   b  are now completely separated, the handle  108  having been torn along the extension line  300  depicted in  FIG. 3 . 
     The user  200  is, as a result, able to carry one secondary package  102   a ,  102   b  in each hand, rather than carrying the entire composite package  100  in one hand as depicted in  FIG. 2 . This gives the user  200  a greater degree of balance and comfort, as the weight of the primary packages  106  is now distributed more evenly. 
     Furthermore, pronation and flexion of the wrists  204  of the user  200  is further reduced, in that as the secondary packages  102   a ,  102   b  are narrower than the composite package  100 , the user can carry them carried closer to the body, with his arms nearer to a vertical position. In this way a further improvement in comfort is achieved. 
       FIG. 5  depicts the separated secondary package  102   b  in greater detail. The secondary package  102   b , though separated from the composite package, retains the sub-handle  114   b  which corresponds to it; likewise, the secondary package  102   a  (not shown) retains the sub-handle  114   a . And because of the band  106 , the secondary package  102   b  will retain its structural integrity, allowing it to be stored, transported, and manipulated with ease. 
     When the secondary package(s) are extracted from the composite package, it may be the case that certain surfaces are exposed to view which would have remained hidden or obscured by the primary packages within the composite package. 
     Indeed, when the secondary package  102   b  is extracted from the composite package, an interior face  500 , previously hidden within the composite package, is now exposed. 
     The exposure of such a surface offers an increased degree of flexibility. For instance, a secondary barcode may be printed on the interior face  500 , assigning a UPC number for the secondary package  102   b.    
     This gives a great deal of flexibility to the consumer and to the seller, permitting the purchase of the entire composite package  100  in its initial state; one or more of the secondary packages  102   b  which have been extracted from a composite package  100 ; or even one or more of the primary packages  104  which have been taken from a broken-open secondary package  102 . 
     Additionally, other complementary information such as promotional messages, recipes, supplementary instructions, etc. may be disposed on the surface area offered by the interior face  500 . 
     Thus, the secondary package  102   b  having been extracted from the composite package, the user  200  can then break the band  106 , so as to remove a primary container  106  for consumption of the product contained therein. 
       FIG. 6  is a detail view of the attachment of one extremity  110  of the handle  108  to the secondary packages  102   a ,  102   b.    
     At the extremity  110 , the handle  108  has an attachment region  600 . The attachment region  600  is essentially a portion of the surface of the handle  108  at the extremity  110  which is configured to be attached to one or more of the primary packages  104 , thereby retaining the handle  108  to the secondary packages  102   a ,  102   b . This adhesion is most commonly achieved by the way of glue or other adhesive substance, though other means of attaching the handle  108  may be possible. 
     The attachment of the handle  108  will now be discussed in further detail. First, it will be noted that the attachment region  600  is partially split, forming from it strips  602   a ,  602   b . The two strips  602   a ,  602   b  are angled away from a centreline  604  of the composite package  100 , at the angles of attachment θ 1 , θ 2 . 
     The attachment of the two strips  602   a ,  602   b  to the secondary packages  102   a ,  102   b  achieves several results. First, when the composite package  100  is whole, the angled attachment serves to permit the disposition of the handle  108  between the secondary packages  102   a ,  102   b , and to support the weight of the two secondary packages  102   a ,  102   b  without any tearing or slipping where the strips  602   a ,  602   b  are attached to said secondary packages  102   a ,  102   b.    
     Second, when the secondary packages  102   a ,  102   b  are extracted from the composite package  100  and carried individually, as depicted e.g. in  FIG. 4 , the off-centre attachment of the sub-handles  114   a ,  114   b  will tend to cause the secondary packages  102   a ,  102   b  to rotate outwards. The attachment of the strips  602   a ,  602   b  at an angle θ 1 , θ 2  relative to the centreline  604  means that any twisting or shear of the handle  108  at attachment region  600  will be minimized. 
     It will also be noted that, in  FIG. 6 , the angles of attachment θ 1 , θ 2  are equal, as the composite package is symmetrical across the centreline  604 . It will be readily understood that the angles of attachment may vary from one side to the other, and in any case will depend on the exact dimensions of the primary containers  104  and the configuration of the composite package  100 . However, in most cases the angle of attachment will be between 10° and 60°, and most frequently between 10° and 30° for the most commonly-encountered applications. 
     The structure of the handle  108  in the form of a single piece of adhesive plastic table has already been presented. 
     Additionally, the handle may comprise a reinforcement means, which may be of particular utility where the composite package is particularly heavy or where it is desirable to provide extra padding for where the user will seize the handle. 
     Thus, in the present embodiment, the reinforcement is provided in the form of a backing member  604  in replacement to the gripping member thereby bringing more comfort to the end user. The backing member  604  is a flat member of moderate rigidity, which is laminated to the handle  108 , over a portion of the length thereof. 
     More specifically, as the handle  108  of the present invention is an adhesive tape, as discussed above with reference to  FIG. 1 , the backing member  604  is simply affixed to the adhesive side of the handle  108 . This is particularly advantageous, in that it simplifies the process for manufacturing the handle; the attachment region  600  is effectively delimited by the backing member  604 . 
     Moreover, such a configuration is advantageous in that it can facilitate the assembly of the composite package  100 . By providing the handle and the backing member in such a laminated form, it may be advantageous to provide the handle  180  in a pre-cut form where an excess portion of the material from which the backing member  604  is fabricated covers and protects the attachment regions  600 . In such a case, the assembler would need merely to peel off the excess backing member material to expose the adhesive attachment regions  600 , then apply the handle  108 . 
       FIG. 7  depicts a variant embodiment of the invention. In  FIG. 7 , a composite package  700  is provided adhesive tape strips  700   a ,  700   b , which are respectively disposed relative to a centreline  703  at the attachment angles φ 1 , φ 2 . Moreover, a handle  704  is provided in a different configuration than the embodiment discussed with respect to  FIGS. 1-6 : a pre-cut perforation line  706  is provided with a pre-cutting that extends over the entire length of the handle  704 , and the handle  704  is of a uniform width over its entire length. 
     The adhesive tape strips  702   a ,  702   b  are here simply affixed to the extremity  708  of the handle; no cutting, slicing, or other such manipulation is required beyond that which is necessary to provide the tape strips  702   a ,  702   b  in the correct length. The adhesive tape strips  702   a ,  702   b  therefore constitute the attachment region of the handle  704 . 
     A composite package  700  configured this way can therefore be fabricated with great efficiency, as the amount of material handling and fabricating operations required are minimized. A composite package such as depicted in  FIG. 7  is thus particularly well-suited for high-speed, high-volume production. 
       FIG. 8  is a top view of a composite package  800  according to a third embodiment of the invention. As in the embodiments previously depicted, the composite package  800  comprises a plurality of primary packages  802  grouped into secondary packages  804   a ,  804   b , and provided with a handle  806 . 
     In the embodiment of  FIG. 8 , however, the primary packages  802  are grouped in a close-packed arrangement. This close-packed arrangement will give an additional measure of structural strength and rigidity to the secondary packages  804   a ,  804   b  when the two are extracted from the composite package  800 . 
     Such a close-packed arrangement also maximizes the number of primary packages  802 , and thus the total volume of product, that can be stored in a given volume of space. The storage, shipping, and stocking for sale of the composite packages are thereby optimized. 
     While the embodiments described in the preceding discussion illustrate the invention, it will be understood that variations are possible without departing from the overall scope of the invention. 
     For instance, it will be well understood that the actual number and configuration of the primary and secondary packages may be varied. For instance, there may be provided three secondary packages of four primary packages each, or two secondary packages of four primary packages each, or any other such permutation as may be desirable and appropriate. It may also be the case that one or more of the secondary packages consists of a single, large primary container. In any event, the handle will be divided into as many sub-handles as there are secondary packages, each sub-handle corresponding to one of the secondary packages. 
     Also, it may be desirable to apply other techniques and structures known in the packaging arts. For instance, it may be advantageous to provide an envelope, such as one fabricated from stretchable or heat-shrunk plastic film, to form the secondary and/or composite packages. Forming the secondary and/or composite packages with an envelope will help to maintain their structural integrity and facilitate their handling during transport, sale, and use. 
     Finally, other means of attaching the handle to the secondary packages, such as hot glue or thermal bonding, may be envisioned. Such means can be selected by the person of skill in the art as appropriate for the size, form, weight, and material properties of the packages in question. 
     It should be understood that various changes and modifications to the presently preferred embodiments described herein will be apparent to those skilled in the art. Such changes and modifications can be made without departing from the spirit and scope of the present invention and without diminishing its attendant advantages. It is therefore intended that such changes and modifications be covered by the appended claims.
