    : tIdInterwovenNRPortblDCCTLD5069451 I.DOC-I H04/2013 CONTAINER FOR STORING ITEMS Technical Field of the Invention 5 The present invention relates to a container for storing items; a blank for forming a container; and a method of storing items in a container. Background of the Invention 10 Previously, items have been packed in containers by performing the following steps: 1. folding a blank of a regular slotted carton (RSC) to form a container where the bottom major and minor flaps are folded in and glued closed; 15 2. placing items into the container through the top open end; 3. spraying beads of hot melt glue on top of the minor flaps; 4. folding the top major flaps over the top minor flaps so as to close the top of the container; and 5. applying downward pressure onto the major flaps so that they contact underlying 20 minor flaps. The space between the top of the packed items and the major flaps, hereafter referred to as the head space, is dependent on the size and quantity of the items being packed. When there is a lot of head space, the inside minor flaps have no underlying support and, as a 25 result, are typically driven down into the carton when the downward pressure is applied to the major flaps in step (5). The minor flaps hinge against respective wall panels and have a tendency to angle away from the major flaps. As such, there may be little to no contact between the major and minor flaps resulting in a defective connection. This can result in the major flaps unintentionally popping open. 30 It is generally desirable to seal closed a RSC type container with a hot melt closing unit : tIdInterwovenNRPortblDCCTLD5069451 I.DOC-I H04/2013 -2 that glues the inside minor flaps to the outside major flaps in an effective manner. In particular, it is desirable to do so when the container has a lot of head space once the items are packed. 5 Previous attempts to address this problem have involved fully die cutting the carton. In doing so, the container is generally more expensive. Further, expensive tooling required to manufacture such a container. Otherwise, the problem has been ignored. It is generally desirable to overcome or ameliorate one or more of the above mentioned 10 difficulties, or at least provide a useful alternative. Summary of the Invention In accordance with one aspect of the invention, there is provided a container for storing 15 items, including: (a) four wall panels coupled together to form a parallelogram; (b) first and second pairs of minor flaps, minor flaps of the first and second pairs extending from opposed top and bottom ends of respective first and third ones of said wall panels; 20 (c) first and second pairs of major flaps, major flaps of the first and second pairs extending from opposed top and bottom ends of respective second and fourth ones of said wall panels; and (d) fastening flaps including a fastener for coupling the minor flaps to corresponding sections of overlying major flaps, 25 wherein the fastening flaps are adapted to move independently to respective minor flaps so as to be substantially parallel with the major flaps when they are folded towards a closed position. Preferably, the fastening flaps are formed integrally with respective minor flaps. 30 Preferably, the fastening flaps are cut from respective minor flaps.
    : tIdInterwovenNRPortblDCCTLD5069451 I.DOC-I H04/2013 -3 Preferably, the fastening flaps hinge away from respective minor flaps when the minor flaps are forced down into the container as a result of the major flaps being folded closed. 5 Preferably, the fastening flaps and respective minor flaps hinge about a common axis. In accordance with the invention there is also provided a blank for forming a container, including: (a) four wall panels arranged in series, the wall panels being arrangable so as to 10 form a parallelogram; (b) first and second pairs of minor flaps, minor flaps of the first and second pairs extending from opposed top and bottom ends of respective first and third ones of said wall panels; (c) first and second pairs of major flaps, major flaps of the first and second pairs 15 extending from opposed top and bottom ends of respective second and fourth ones of said wall panels; and (d) fastening flaps for coupling the minor flaps to corresponding sections of overlying major flaps, wherein the fastening flaps are adapted to move independently to respective minor flaps so 20 as to be substantially parallel with the major flaps when they are folded towards a closed position. Preferably, the fastening flaps are formed integrally with respective minor flaps. 25 Preferably, the fastening flaps are cut from respective minor flaps. Preferably, the fastening flaps hinge away from respective minor flaps when the minor flaps are forced down into the container as a result of the major flaps being folded closed. 30 Preferably, the fastening flaps and respective minor flaps hinge about a common axis.
    : tIdInterwovenNRPortblDCCTLD5069451 I.DOC-I H04/2013 -4 In accordance with the present invention there is also provided a method of packing items in the above-described blank, including the steps of: (a) folding the blank so that the four wall panels couple together to form a parallelogram; 5 (b) applying a fastener between corresponding bottom major and bottom minor flaps; (c) folding bottom major flaps over bottom minor flaps so as to generally close a bottom of the container; (d) placing the items into the container; (e) applying a fastener between the fastening flaps and the major flaps; and 10 (f) folding top major flaps over top minor flaps so as to generally close a top of the container. Preferably, the method includes the step of the step of coupling a first one of said wall panels to a fourth one of said wall panels in the series of wall panels. 15 The container is particularly useful for where the items are not self supporting, such as bags of loose salad or bags of chips. Items such as this generally vary in height and are normally affected by the amount of nitrogen pumped into the bags to help retain freshness. If the items are not able to add any resistance to the minor flaps during the carton sealing 20 process then the major flaps generally push the minor flaps down into the carton which reduces the ability to apply pressure to set off the hot melt glue. The end result is little or no bond occurring between the major and minor flaps allowing the carton to 'pop open'. The container advantageously addresses this problem or at least provides a useful alternative. 25 Brief Description of the Drawings Preferred embodiments of the present invention are hereafter described, by way of non limiting example only, with reference to the accompanying drawing in which: 30 Figure 1 is a top perspective view of a container; : tIdInterwovenNRPortblDCCTLD5069451 I.DOC-I H04/2013 -5 Figure 2 is a plan view of a blank that is foldable into the container shown in Figure 1; Figure 3 is a side perspective view of the container shown in Figure 1 during a stage of assembly; Figure 4 is side perspective view of the container shown in Figure 1 during another stage 5 of assembly; Figure 5 is a top perspective view of the container shown in Figure 1 during yet another stage of assembly; Figure 6 is top perspective view of the container shown in Figure 1 during still another stage of assembly; 10 Figure 7 is top perspective view of the container shown in Figure 1 during again another stage of assembly; and Figure 8 is top perspective view of the container shown in Figure 1 a final stage of assembly 15 Detailed Description of Preferred Embodiments of the Invention The container 10 shown in Figure 1 is used to store items (not shown), such as loosely packed bags of lettuce leaves or chips, for example. The container 10 is constructed from the blank 12 shown in Figure 2 which can be folded into the container 10 in the manner 20 shown in Figures 3 to 8. The container 10 includes: a. four wall panels 14a, 14b, 14c, 14d coupled together to form a parallelogram; b. first and second pairs of minor flaps 16a, 16b, 18a, 18b, minor flaps of the first and second pairs extending from opposed top and bottom ends 20a, 20b of respective 25 first 14a and third 14c wall panels; c. first and second pairs of major flaps 22a, 22b, 24a, 24b, major flaps of the first and second pairs extending from opposed top and bottom ends 20a, 20b of respective second 14b and fourth 14d wall panels; and d. fastening flaps 26 including a fastener 28 for coupling the minor flaps 16a, 16b, 30 18a, 18b to corresponding sections of overlying major flaps 22a, 22b, 24a, 24b.
    : tIdInterwovenNRPortblDCCTLD5069451 I DOC- H 04/2013 -6 The fastening flaps 26 are adapted to move independently to respective minor flaps 16a, 16b, 18a, 18b so as to be substantially parallel with the major flaps 22a, 22b, 24a, 24b when they are folded towards a closed position shown in Figure 1. 5 Preferred embodiments of the container 10 are described, by way of non limiting example, with reference to the container 10 including two fastening flaps 26 coupled to top flaps 16a, 18a of the first and second pairs of minor flaps. Alternatively, the fastening flaps are coupled to top and bottom flaps 16a, 16b, 18a, 18b of the first and second pairs of minor flaps, or any other suitable combination. 10 As shown, the fastening flaps 26 are preferably formed integrally with respective minor flaps 16a, 18a. The fastening flaps 26 are cut from respective minor flaps 16a, 18a. The fastening flaps 26 hinge away from respective minor flaps 16a, 18a when the minor 15 flaps are forced down into the container 10 as a result of the major flaps 22a, 24a being folded closed in the manner shown in Figure 8. The fastening flaps 26 and respective minor flaps 16a, 18a hinge about a common axes "Ai" and "A 2 ". The fastening flaps 26 are located centrally along respective common axes Ai and A 2 . As such, the fastening flaps 26 are laterally displaced from the pivot point "P" of the major flaps 22a, 24a and are 20 therefore less effected by downward pressure applied to the minor flaps 16a, 18a when the container 10 is closed. The fastening flaps 26 are preferably double cut into respective minor flaps 16a, 18a. In doing so, the fastening flaps 26 readily separate from respective minor flaps 16a, 18a as the 25 major flaps 22a, 24a are folded closed. The double cut will flex as it folds allowing the fastening flaps 26 to pop up out of the minor flaps 16a, 18a. The fastening flaps 26 include an adhesive 28 to fasten respective minor flaps 16a, 18a to corresponding major flaps 22a, 24a. 30 The major flaps 22a, 22b, 24a, 24b are larger than the minor flaps 16a, 16b, 18a, 18b. The major flaps 22a, 22b, 24a, 24b and the minor flaps 16a, 16b, 18a, 18b substantially close : tIdInterwovenNRPortblDCCTLD5069451 I.DOC-I H04/2013 -7 top and bottom sides of the container 10. The first wall panel 14a includes a side flap 30 extending at least partially over the fourth wall panel 14d for coupling the wall panels together. The side panel 30 is coupled to the 5 fourth wall 14d panel with an adhesive. A blank 12 can be folded into a container 10 and packed with items by effecting the following method steps: 10 a. folding the blank 12 so that the four wall panels 14a, 14b, 14c, 14d couple together to form a parallelogram; b. applying a fastener (not shown) between corresponding bottom major and minor flaps 16b, 18b, 22b, 24b; c. folding bottom major flaps 22b, 24b over bottom minor flaps 16b, 18b so as to 15 generally close a bottom of the container 10; d. placing the items into the container 10; e. applying a fastener 28 between the fastening flaps 26 and the major flaps 22a, 24a; and f. folding top major flaps 22a, 24a over top minor flaps 16a, 18a so as to generally 20 close a top of the container 10. The method preferably includes the step of coupling a first one of said wall panels 14a to a fourth one of said wall panels 14d in the series of wall panels. The first fall panel 14a is coupled to the fourth wall panel 14d with a fastener. The fastener is preferably an 25 adhesive. Alternatively, any other suitable fastener can be used. The step of applying a fastener 28 includes the step of applying glue to the fastening flaps 26. The step of applying glue 28 to the fastening flaps 26 includes the step of applying two lines of glue beads 28 to each one of said fastening flaps26 in the manner shown in Figure 30 7.
    : tIdInterwovenNRPortblDCCTLD5069451 I DOC- H 04/2013 -8 The fastening flaps 26 preferably extend at an angle of substantially ninety degrees to respective wall panels when the step (f) has been effected. The container 10 is preferably RSC that allows the flaps 16a, 16b, 18a, 18b, 22a, 22b, 24a, 5 24b to be closed / glued shut with effectively non-supporting product inside the container 10 which in turn is unable to support the minor flaps 16a, 16b, 18a, 18b as part of the gluing process. This is also achieved at by utilising the same amount of material in the container 10 which effectively keeps the container 10 cost the same. 10 By creating a 'flap inside a flap' you achieve two independent flaps in one. The inner flap, i.e. the fastening flap 26, remains at a substantially ninety degree angle when folded as part of the closing process, where as the 'outer' part of the flap. i.e. the minor flap 16a, 16b, continues to protrude into the container 10 in the same manner the prior art containers. The glue is applied to the fastening flaps 26 and because it remains at a ninety degree angle 15 there is a better chance for glue adhesion between the major and minor flaps 16a, 16b, 18a, 18b, 22a, 22b, 24a, 24b. More consistent and even compression is able to be applied to the top of the container 10 during the sealing process. Advantageously, the container 10 utilizes the existing material in the container there by 20 keeping the cost of the carton low. The fastening flaps 26 act independently to their respective minor flaps 16a, 18a and do not follow the same angle when folded. The fastening flaps 26 advantageously remain at a ninety degree angle to the respective wall panels 14a, 14c allowing for a flat and consistent 25 glue area to assist with the bonding process. The glue bead 28 has even pressure applied to the entire length providing a better bond overall. Advantageously, the container 10 solves the problem of sealing the top major flaps 22a, 24a without increasing the cost of manufacture of the container 10. 30 Many modifications will be apparent to those skilled in the art without departing from the : tIdInterwovenNRPortblDCCTLD5069451 I.DOC-I H04/2013 -9 scope of the present invention Throughout this specification, unless the context requires otherwise, the word "comprise", and variations such as "comprises" and "comprising", will be understood to imply the 5 inclusion of a stated integer or step or group of integers or steps but not the exclusion of any other integer or step or group of integers or steps. The reference to any prior art in this specification is not, and should not be taken as, an acknowledgment or any form of suggestion that the prior art forms part of the common 10 general knowledge in Australia.
