Patents Act 1990 PACKWEST PTY LTD COMPLETE SPECIFICATION STANDARD PATENT Invention Title: A carton divider system The following statement is a full description of this invention including the best method of performing it known to us:- Field of the Invention This invention relates to packaging of articles. More particularly, the invention relates to a carton divider system for packaging articles in a carton or box.
Background to the Invention Certain articles, in particular bottles or jars, are normally packaged together in a carton or box for transportation purposes. It is necessary, where the bottles or jars are of a frangible material such as glass or where the articles have labels which are not to be scuffed, to separate the articles laterally with respect to each other in the carton. For this purpose, separators or carton dividing systems have, in the past, been used.
One of the systems of which the applicant is aware makes use of separate planar panels or strips. Depending on the number of articles to be packed in the carton, the separating system comprises a plurality of first strips extending in a first direction and a plurality of second strips extending in a second direction, substantially normal to the first direction. The first strips have slots opening in to one of the ends, for example, their upper ends, with the second strips then having slots opening into the other of the ends, for example, their lower ends. The first strips and second strips are secured together by meshing their slots together to form a grid-like arrangement when viewed in plan. This arrangement is cumbersome and difficult to use in practice as the strips can work apart.
Another system makes use of interlocking strips but some of the strips have to be folded to engage with others of the strips. Folding of the strips causes problems and is unsightly.
Summary of the invention According to the invention, there is provided a carton divider system for packing a plurality of articles in a carton, the system including: at least one first panel, the at least one first panel defining at least one closed slot with a slot extension extending from at least one end of the at least one slot; and at least one second panel engageable with the at least one first panel, the at least one second panel defining a receiving formation which is received in the at least one slot to secure the panels together, the at least one second panel further having a locking means which releaseably locks the at least one second panel and the at least one first panel together, a part of the locking means cooperating with the slot extension of the at least one slot for facilitating securing of the at least one second panel to the at least one m:\speci110000\114-115\114677cmpchb.doc first panel and for inhibiting disengagement of the at least one second panel from the at least one first panel.
Generally, the system may include at least one first panel and a plurality of second panels. For example, for packing a dozen wine bottles in a carton, the carton divider system includes two first or primary panels and three second or secondary panels. For a carton accommodating six articles, only one first panel is provided with two second panels. For the sake of clarity, the system will be described with reference to its including a plurality of first panels and a plurality of second panels. It will be appreciated that the number of slots in the, or each, first panel is governed by the number of second panels. In all cases where more than four compartments are to be formed in the carton, the primary panel or panels will therefore have more than one slot.
Typically, the panels may be made of a cellulosic material, more particularly, a board material. The board material gives the system the requisite degree of stiffness.
The panels may be engageable with one another in such a manner as to form a collapsible assembly and, when the assembly is in its collapsed configuration, the panels overlie one another to form a compact assembly for transportation purposes.
When the assembly is in its erected configuration, the first panels may be arranged in spaced parallel relationship to one another and the second panels may also be arranged in spaced parallel relationship to one another but extending substantially orthogonally with respect to the first panels to form a plurality of compartments in each of which an article to be packed in the carton is received Hence, the assembly may form a pantograph-like structure.
To facilitate collapsibility of the assembly, the at least one slot of the at least one first panel may have a width which exceeds the thickness of the first panel.
The slot extension of the at least one slot may be in the form of a slit extending from one end of the slot. In contradistinction to the slots having a discrete width, each slit may be in the form of a cut formed in the board of the panel.
Further, to inhibit withdrawal of the locking means of the second panel from its associated slot of the first panel, the slit may be offset with respect to a centre of the slot. Still further, the slit may be angled with respect to a longitudinal axis of the slot.
In use, the slit may be at a top of the panel.
The at least one second panel may have a central portion with a side portion demarcated on each side of the central portion. Each side portion may terminate in a part of the' locking means. Each part of the locking means may be in the form of a m:\specR1 10000\114-115\114677cmpchb.doc tongue-like formation, each tongue-like formation being demarcated by slots opening out into an operatively top end and an operatively bottom end of the second panel.
Where the second panel is to be used in a carton accommodating six articles, material of the second panel between the top and bottom slots may define the central portion and serves also as the receiving formation.
Where the second panel is to be used with twelve articles, the central portion may be a middle part of the second panel having a width dimension approximating that of a width of the article to be accommodated in the compartment. The central portion may be demarcated with respect to the side parts by upper and lower open slots on each side of the central portion., the part of each second panel between each aligned pair of upper and lower slots defining each receiving formation of the second panel.
The tongue-like formation of the second panel to be received through the slit of the associated first panel may have a height which is lower than that of a top part of the central portion of the second panel.
In the case where the system is to be used with cartons accommodating six articles, the overall height of the second panels may be less than that of the first panels.
This facilitates insertion of the tongue-like formations of the second panels through their associated slits of the first panels without the need for folding the tongue-like formations.
Brief Description of the Drawings The invention is now described by way of example with reference to the accompanying diagrammatic drawings in which: Figure 1 shows a three dimensional view of a carton divider system, in accordance with the invention; Figure 2 shows a side view of one of the panels forming part of the system of Figure 1; and Figure 3 shows a side view of another of the panels forming part of the system of Figure 1.
Detailed Description of the Invention In the drawings, reference numeral 10 generally designates a carton divider system, in accordance with the invention. The system 10 comprises a plurality of first or primary panels 12 and a plurality of second or secondary panels 14.
In the system 10 illustrated in Figure 1 of the drawings, the system 10 comprises two primary panels 12 and three secondary panels 14 to define twelve compartments m:\speci\110000\114-115\114677cmpchb.doc 16, in each of which an article, such as a wine bottle to be packed in a carton (not shown), is received. In respect of outer compartments, walls of the carton complete the compartments. Those skilled in the art will appreciate that, in use, in the packing of the bottles in a carton, the articles are first placed in the carton. After placing of the articles in the carton, a carton divider system is placed in the carton to separate the articles laterally with respect to each other to inhibit bumping of the articles against each other.
Each primary panel 12, one of which is shown in greater detail in Figure 2 of the drawings, comprises a body member 18 having a top 20, a bottom 22 and a pair of opposed sides 24.
A plurality of closed slots 26 extend parallel to the sides 24 of the body member 18. A part of one of the second panels 14 is accommodated in each slot 26, as will be described in greater detail below.
As indicated, each slot 26 is a closed slot so that a bridging portion of material 28 is arranged between an operatively upper end of the slot 26 and the top 20 of the panel 12. Similarly, a bridging portion of material 30 is arranged between a bottom of each slot 26 and the bottom end 22 of the panel 12.
A slot extension in the form of a slit 32 extends from a top of each slot 26.
Preferably, the slit 32 is offset with respect to a centre of the slot 26 and, further, is angled with respect to a longitudinal axis of its associated slot 26.
Typically, each slot 26 has a width greater than a thickness of the body member 18, which is of a board material, while the slit 32 is in the form of a cut in the material of the body member 18. For example, while the body member 18 may have a thickness of 1mm or less, the slot 26 has a width of approximately 2 to 6mm, preferably, 2 to and, optimally, about 3mm. This facilitates collapsibility of the system 10, as will be described in greater detail below.
An operatively lower end of each side 24 is tapered or chamfered inwardly as indicated at 34. Further, in the bottom end 22 of the body member 18, substantially Vshaped cut-outs 36 are formed intermediate the slots 26. The chamfer 34 and the Vshaped cut-outs 36 facilitate placement of the system 10 in the carton between the articles.
Referring to Figure 3 of the drawings, one of the second panels 14 is illustrated and is described in greater detail.
Each second panel 14 has a body member 40 of a cellulosic material, such as a board material. As in the case in respect of each first panel 12, the thickness of the body member 40 of the second panel 14 is of the order of 1mm or less.
m:\speci\110000\114-115\114677cmpchb.doc Each second panel 14 has a top 42, a bottom 44 and a pair of opposed sides 46.
As is the case with the first panels 14, the junction between the bottom 44 and the sides 46 is in the form of a chamfer 48. The chamfer 48 serves the same purpose as the chamfer 34 of each of the first panels 12.
For the illustrated embodiment, each second panel 14 has a central part 50. A side part 52 is arranged on each side of the central part 50. Each side part 52 is demarcated with respect to the central part by an upper, open slot 54 and a lower, open slot 56. The upper slot 54 opens out into the top 42 of the body member 40 and the lower slot 56 opens out into the bottom 44 of the body member 40. The part of the second panel 14 between each pair of aligned upper slots 54 and lower slots 56 forms a receiving formation which is received in one of the slots 26 of one of the first panels 12.
An operatively outer side 58 of each bottom slot 56 tapers outwardly so that the slot 56 flares towards its opening in the bottom ehd 44 of the body member 40. This facilitates insertion of a tongue-like formation, or tongue, 60 arranged outwardly of the slot 56, through the slot 26 of the first panel 12 as will be described in greater detail below.
In addition, a further tongue-like formation, or tongue, 62 is defined outwardly of each upper slot 54 at the top of each side portion 52. Each tongue 62 tapers downwardly from the slot 54 to the side 46 to form an inserting edge 64 receivable through the slit 32 of the first panel 12, in use.
The central part 42 also has a V-shaped cut-out 66 formed in its bottom end 44 for the same purpose as the V-shaped cut-outs 36 of the first panels 12.
The chamfers 34 and the cut-outs 36 of the first panels 12 and the chamfers 48 and cut-outs 66 of the second panels 14 provide reduced regions of contact with bottle labels and relief from interference and displacement of the bottle label, particularly where the labels have not set on the articles, such as may occur with the use of wet gum-type labels.
The second panel 14 shown in Figure 3 of the drawings is for use with the system of Figure 1 where twelve articles or bottles are to be packed in a carton. Where, for example, six articles or bottles are to be packed in a suitably dimensioned carton, each second panel 14 omits the central part 50 so that only one upper slot 54 and one lower slot 56 is defined substantially centrally in the body member 40. In the latter case, the slot 56 need not be flared.
In use, to form the system 10 of Figure 1, two first panels 12 and three second panels 14 are used. The tongue 60 of one of the second panels 14 is inserted through m:\specd110000\114-115\114677cmpchb.doc the slot 26 of a first of the first panels 12 to receive part of the bridging portion 30 of the first panel 12 in the slot 56 of the second panel 14. The tongue 62 is urged through the slit 32 of the relevant slot 26 of the first panel 12. Insertion of the tongue 62 is facilitated by bowing or bending the first panel 12 and the second panel 14 slightly with respect to each other. However, if the tongue 62 of the second panel 14 is inserted in a direction towards the direction in which the slit 32 is angled, the need to bow or bend either or both of the first panel 12 and the second panel 14 may be obviated.
Second and third of the second panels 14 are then inserted into the remaining slots 26 of the first of the first panels 12. The second of the first panels 12 is mounted relative to the other side of each of the second panels 14 in a similar manner to that described above by inserting the tongues 60 of the second panels 14 through the slots 26 of the second of the first panels 12 and inserting the tongues 62 through the slits 32 of the relevant slots 26 of the second of the first panels 12. In so doing, the system as illustrated in Figure 1 of the drawings is formed.
Due to the fact that the slits 32 are offset and angled with respect to a longitudinal axis of the slots 26 the chances of the tongues 62 being withdrawn through the slits 32 unintentionally are very small. This is further facilitated due to the fact that each slit 32 is in the form of a cut which has a width less than the thickness of the body member 40 of each second panel 14.
Secondly, due to the fact that the slots 26 are substantially wider than the thickness of the body members 40, the system 10 is collapsible where the panels 12, 14 overlie one another in a collapsed configuration. The panels 12 are displaced relative to each other, pantograph-fashion, to form the erected carton divider system 10, as illustrated in Figure 1 of the drawings.
It is a particular advantage of the invention that a system 10 is provided which makes use of closed slots 26 thereby inhibiting separation of the panels 12 and 14 with respect to each other. In addition, it is a major advantage of the invention that, with the provision of the slits 32, the need to fold the tongues 60 to insert them through the slots 26 is obviated. It will be appreciated that folding the tongues 60, besides causing unsightly fold lines in the panels 14, could cause the tongues 60 to extend at an angle relative to a plane of the panels 14. These tongues could then snag the labels on the articles or bottles causing tearing or displacement of the labels. This renders the articles unattractive and could be rejected by a wholesaler or retailer of the articles or a customer purchasing the articles. Further, a double thickness of panel material, such as may occur as a result of a folded- tongue, may prevent easy insertion of a system employing folding tongues into the carton. A folded tongue may cause such m:\speci\110000\114-115\114677cmpchb.doc interference as to inhibit the insertion of the panel into a space between adjacent articles within the confines of the carton. As described, the provision of the slits 32 of the present invention obviates the need for folding of the tongues 60 thereby largely overcoming this problem.
In addition, by eliminating the need for folding any part of the panels of the present invention, the strength and stiffness of the system 10 is enhanced in comparison with other systems of which the applicant is aware.
Still further, the elimination of the need for folding means that the system 10 can be assembled far more rapidly than systems which incorporate folding. It will be appreciated that, due to the fact that manual labour is required to assemble the systems, any improvement in productivity has major cost benefit implications.
It will be appreciated by persons skilled in the art that numerous variations and/or modifications may be made to the invention as shown in the specific embodiments without departing from the spirit or scope of the invention as broadly described. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive.
