Description

A BLANK FOR LIQUID TIGHT CARTON

Field of the Invention

This invention relates to packaging and in particular relates to cartons and blanks which can be formed to produce such cartons.

Background Art

In the fast food industry and other applications it is desirable to provide packaging which is capable of accommodating liquid or near liquid type foods. In the past this has generally been provided by moulded plastic packaging. It has not been the practise to utilise cardboard carton material blanks in relation to such packaging due to the difficulties of folding the cartons efficiently to produce a carton having a closed base. Other than the cost a difficulty with known cartons which provide a liquid bearing space is that they are generally preformed to the desired configuration and as a result occupy considerable amount of space. A problem with providing collapsible cartons which can contain liquid has been the capacity to readily form such cartons and provide them in a flat form in order that they can be readily erected when required

Disclosure of the Invention

Detailed Description of Specific Embodiments

The first embodiment as shown in the drawings comprises a carton blank 10 which is capable of being folded to define a carton which has a configuration of a rectangular prism and which defines a space of which the lower portion is liquid tight. The blank 10 is formed of a cardboard or like material which has waterproof properties and/or which is coated or similarly treated to render it at least substantially water proof.

The carton blank 10 comprises a central panel 11 which is of a rectangular configuration corresponding to the desired configuration of the floor of the carton. Each side of the central panel 11 is connected through a fold line to a side panel 13, 15, 17 and 19. The adjacent sides of adjacent side panels are interconnected by webs 21 and each web 21 is associated with an intermediate fold line 23 which extends across the respective web from the respective corner of the central panel 11 to the outer edge of the web 21 whereby the intermediate fold line 23 bisects the angle between the adjacent edges of adjacent side panels.

The junctions between the central panel 11 and each of the side panels 13, 15, 17 and 19 are defined by fold lines and the junctions between each of the side panels and the respective webs 21 are also defined by fold lines.

In addition one second side panel 13 is connected through a fold line to an extension panel 25 which provides the closure panel for the carton. The outer edge of the extension panel is provided with a locking tab 27 which is receivable in a slot 29 provided on the other second side panel 17 when the carton is in the erect condition and when the closure panel 25 is in the closed position.

In order to provide a self erecting carton the pair of opposed first side panels 15 and 19 are folded along their perspective fold line into face to face engagement with the central panel 11 as shown in Figure 2. As a result the respective webs 21 are also folded to be face to face engagement with their adjacent second side panels 13 and 17.

The portion of each web 21b which is most remote from the respective first side panel 15 or 19 is bonded into face to face engagement with the adjacent second side panel 13 or 17.

In use it is intended for the carton to be provided to users in a form with the remote portions 21b of the webs 21 bonded to the second side panels 13 and 17 as shown at Figure 2. When it becomes necessary to erect a carton the user can fold the carton by applying a force to the first side panels 15 and 19 such that they fold away from the central panel 11. The erection of the carton can alternatively be effected by folding the second side panels 13 and 17 towards each other. In both instances because of the bonding of the remote portions 21b of the webs to the second side panels 13 and 17, the portions 21a and 21 b of the webs 21 will fold about their intermediate fold line 23, and the second side panels 13 and 17 or first panels 15 and 19 respectively are also caused to fold about their junction with the central panel 11 to move correspondingly out of the planar condition such that when the first side panels 15 and 19 or the second panels 13 and 17 are substantially perpendicular to the central panel 11 so too are the second side panels 13 and 17 or the first panels 15 and 19 respectively. As a result, as shown in Figure 3, the space defined between the central panel 11 and the side panels 13, 15, 17 and 19 is closed and can be filled with a liquid or liquid-like material up to the uppermost level of the outer end of the intermediate fold line 23 of the web 21. Once the container has been filled as desired the closure panel 25 can be folded into engagement across the upper surface of the carton and the locking tab 27 can be engaged in the slot 29 provided in the opposite side panel 17.

In an alternative embodiment of the invention the web 21 is of a square configuration and as a result when the carton is folded the outer end of the intermediate fold line 23 terminates at the upper edge of the respective second side panel 13. The advantage of this arrangement is that when the fluid tight space is defined by the full height if the side walls 13, 15, 17 and 19. In this arrangement the closure panel 25 may take a varied form such that there is no need to provide a locking slot of like aperture 29 in one of the side walls to retain the closure panel in position.

A second embodiment of a carton blank 30 in accordance with the present invention is shown in Figures 4 to 10. Carton blank 30 has similar features to the carton blank 10 described above, and similar parts will be referred to with similar reference numerals. The carton blank 30 comprises a central panel 11 having each side thereof connected via fold lines to side panels 13, 15, 17 and 19.

Adjacent sides of adjacent side panels are interconnected by webs 21 each having an intermediate fold line 23. The junctions between each of the side panels 13, 15, 17 and 19 and the respective webs 21 are defined by fold lines.

The second side panel 13 is connected via a fold line to a first extension panel 25 which provides the closure panel for the carton. The outer edge of the closure panel 25 is provided with a locking tab 27 which is receivable in a slot 29 provided on the other second side panel 17 when the carton is in the erect condition and when the extension panel is in the closed position.

In this embodiment, the other second side panel 17 is provided with a second extension panel 31 which has the same width as the other second panel 17 and the panels 17 and 31 are interconnected by a fold line. In addition the outer edge of the second extension panel 31 is provided with a flange 33 which extends beyond the sides of the second extension panel 31 to provide tabs 36.

As with the first embodiment above, the pair of opposed first side panels 15 and 19 are folded into face to face engagement with the central panel 11 as shown in Figure 5. As a result the respective webs 21 are also folded to be face to face engagement with their adjacent second side panels 13 and 17. Each web 21 b is also bonded into face to face engagement with their adjacent second side panel 13 or 17.

To erect the carton 30, the user folds the second side panels 13 and 17 to their upright position relative to the central panel 11. In so doing, the portions 21a and 21b of the webs 21 will fold about their intermediate fold line 23 causing the first side panels 15 and 19 to fold to be upright relative to the central panel 11 as shown at Figures 6.

As shown in Figures 7 and 8, to further ensure that the carton 30 maintains its erect condition, the second extension panel 31 is folded inwardly such that it lies at the inner face of the other second panel 17 and the flange 33 is engaged with the central panel 11 and the tabs 36 become engaged with the adjacent first panel 15 or 19 to provide frictional resistance to the second extension panel 31 moving out of position. The second extension panel 31 thus provides reinforcement to the carton. As a result the space defined between the central panel 11 and the side panels 13, 15, 17 and 19 is closed and can be filled with a liquid or liquid-like material up to the uppermost level of the outer end of the intermediate fold line 23 of the web 21.

Once the carton has been filled as desired the closure panel 25 can be folded into engagement across the upper surface of the carton and the locking tab 27 can be engaged into the slot 29 provided in the opposite side panel 17.

The first extension panel is formed with a central zone which is defined within a perforated boundary 35. The perforated boundary 35 enables the contents of the closed carton to be accessed for consumption without the need to disconnect the locking tab from the slot 29.

In addition the engagement of the locking tab 27 with the slot 29 is such that disengagement cannot be effected without damaging one or both elements 27 and 29 and as result the tab 27 and slot 29 provide means of determining whether the closed package has been tampered with. As shown in Figure 4, the tab 27 has the configuration of an arrowhead which is supported from the first extension panel by a stem 59 where which the leading edges 51 and the trailing edges 53 and the side edges 55 of the arrowhead all are divergent in the direction away from the outer end Y of the tab 27. As a result the outermost points of the tab 27 at the junction between the trailing edges 53 and the side edges 55 define locking elements X. In addition the slot 29 is formed as a slit portion 29a and a central slot portion 29b which are connected to each other. The slot portion 29b has a greater width than the slit portion 29a and only extends for a portion of the length of the slit 29a. The length of the slot portion 29b is greater than the width of the stem 59 of the tab 27 but less than the width between locking elements X. The length of the slit 29a is equal to or slightly greater than the width between locking elements X.

As shown at Figures 9 and 10 in closing the carton the tab 27 is inserted into the slit 29a and as a result the lower edge of the slit 29a will be resiliently deflected outwardly and the upper edge of the slot portion 29b will be resiliently deflected inwardly. However on the passage of the tab 27 past the slit 29a, there is nothing to restrain the upper edge of the slit 29a from resuming to its normal position at which it is substantially co planar with the remainder of the side panel 17 which contains the slot 29. As a result the locking elements X become entrapped inward of the upper edges of the slit portion 59a as shown at Figure 10.

The result is that the locking tab 27 cannot be readily extracted from engagement with the slot 29 without damaging the locking tab 27 and therefore it can be taken that if the locking tab 27 of a closed carton shows sign of damage that there is a strong likelihood of the carton having been tampered with subsequent to it having been closed.

The carton according to the embodiment has the characteristic that once it has been erected and before it is closed it provides a stable enclosure which will enable it to be readily filled without further manipulation of the carton. In addition once closed it provides a carton which is relatively rigid. These characteristics are enhanced by the reinforcement panel 31. The reinforcement panel 31 can also be provided even if the blank is not provided with a closure panel 25. In such an embodiment, the carton formed will have an open top. The carton blank 30 also has the capacity to indicate whether the closed carton has been tampered with subsequent to closure. It should be appreciated that the scope of the present invention need not be defined by the particular scope of the embodiment described above in this specification.
