[0039] FIGS. 12a to 12c are perspective, exploded and cross-section views of a second embodiment of the alternative removable valve to be used with the package of FIG. 1.

[0040] With reference to FIGS. 1 to 5, there is shown a carton 4, the carton 4 being configured to receive a flexible bag to contain liquid 8 therein. The bag has a dispensing outlet 10, which can be defined as a spout, for dispensing the liquid 8 such that the carton 4 and the bag define a package 2 for containing and dispensing liquid according to a preferred embodiment of the present invention.

[0041] The bag can be a conventional flexible bag being formed of substantially impermeable material suitable for use with flowable products that require storage and dispensing. The flowable products can include dry or liquid flowable products, being of the sort that readily flow under gravity. Examples of liquid flowable products include chemicals or chemically based products such as cosmetics, inks, paints, solvents, adhesives as well as liquid consumable products including oil, beverages and condiments such as soy sauce, fish sauce, vinegar and the like. Examples of dry flowable products can include powdered or granular materials, such as detergents, salt, sugar or grains. As an example, the embodiments herein have been described to contain and dispense liquid however the person skilled in the art would understand that the embodiments could be used with any suitable flowable product. The bag can be sized to accommodate any capacity as desired but in these embodiments the bag can have a capacity of 10 to 15 Litres. Accordingly, the carton 4 is sized to accommodate the bag.

[0042] The carton 4 has an internal wall 12, the internal wall 12 defining to one side of the wall a first cavity 13 within the carton 4 for locating the bag. The internal wall 12 has an opening 14 in which a body 16 of the spout 10 is located whereby an outer end 18 of the spout 10 lies within a second cavity 20 defined between an opposite side of the internal wall 12 and adjacent external wall 22 of the carton 4. The carton 4 has a removable area 24 leading into the second cavity 20 to expose the spout outer end 18 and provide access thereto. This provides the advantage that the user can easily locate the spout outer end 18 within the second cavity 20 once the removable area 24 has been removed. Further, if the user uses a sharp object to remove the removable area 24, as the spout outer end 18 is isolated from the bag by the internal wall 12, it is much less likely that the bag will be pierced by the sharp object.

[0043] In the described embodiments, the removable area 24 is partially within the adjacent external wall 22. The removable area 24 can also be located partially within a further external wall 26 transverse to the adjacent external wall 22. This provides easy access to the spout outer end 18. In an example, the removable area 24 can be wholly within the adjacent external wall 22.

[0044] With regard to FIGS. 3 and 4, the opening 14 of the internal wall 12 has a recess 28 into which part of the spout body 16 can be fittingly received. The internal wall 12 can have fixing means for fixing the spout body 16 in the recess 28. The fixing means can be defined as a support portion 30 within the internal wall 12. The support portion 30 is arranged to extend between the spout body 16 and an adjacent edge of the internal wall 12 such that the recess 28 and support portion 30 circumferentially surround the spout body 16. The support portion 30 can itself be fastened within the internal wall 12, for example by adhesive. Accordingly, the spout body 16 is securely retained in the internal wall 12 without regard to an orientation of the package 2. In a preferred embodiment, the support portion 30 and spout body 16 can be formed as a single unit 31, shown in FIG. 10. Therefore, the user does not need to reach into the carton 4 to find the spout outer end 18 and to re-orient it for use.

[0045] The spout outer end 18 can have a removable cap 32 or a removable valve 34.

[0046] According to the embodiments shown in FIGS. 3, 4 and 7, the cap 32 can be attachable by a screw and thread arrangement, and a corresponding removable tap 34 can be exchanged for the cap 32 to dispense the liquid 8. Alternatively, as shown in FIG. 5, the liquid 8 can be dispensed directly from the package 2 via the spout 10 without the use of a tap 34. Although the second cavity 20, in FIGS. 3 and 4, is sized to accommodate the height of the cap 32, the second cavity 20 may be configured to house a tap 34, either fixed to the bag or removable from the bag such as a removable tap or valve (see FIGS. 7, 11a to 11c and 12a to 12 c). In a preferred embodiment, the spout 10 can have a removable tap 34, 35 or valve 37, 39 so that the liquid 8 can be accessed via the spout 10 directly by removing the removable cap 32, or valve 37, 39 or dispensed by the tap/valve 34, 35, 37, 39 directly.

[0047] The removable valve 37, as exemplified in FIGS. 11a to 11c and 12a to 12c, has a tubular member 80 having an end portion 82 being open and further being arranged to attach over the dispensing outlet 10 of the flexible bag (not shown) to allow the contents of the flexible bag to flow into the tubular member 80. The interior of the tubular member 80 has a transverse wall 84, the wall 84 including a flexible diaphragm 86, a dispensing opening 88 normally closed by the flexible diaphragm 86. The wall also includes a lever 90 extending laterally on an outer side of the wall 84 and connected to the flexible diaphragm 86 to displace the flexible diaphragm 86 from a position where the flexible diaphragm 86 sealably closes the dispensing opening 88 preventing the contents from exiting the bag and a position where the flexible diaphragm 86 is removed from the dispensing opening 88 permitting the contents of the bag to exit. The lever 90 is connected to the flexible diaphragm 86 such that the flexible diaphragm 86 is operable between these two positions by manipulation of the lever 90. The open end of the tubular member 80 is arranged to be attachable to the dispensing outlet 10 by a threaded connection, for example, the internal wall of the open end portion 82 has a thread arranged to be engageable to a corresponding thread on the outer wall of the dispensing outlet 10.

[0048] In FIGS. 11a to 11c, the removable valve 37 is directly attached to the dispensing outlet 10. However in FIGS. 12a to 12c, the removable valve 39 comprises two tubular sections 39a, 39b. The tubular section 39a comprising the wall 84 including the flexible diaphragm 86, dispensing opening 88 and lever 90, is couplable to the dispensing outlet 10 via a threaded tubular section 39b coupled to the lever 90 as described above. The two sections 39a, 39b are couplable by a snap-fit connection. Having the valve 39a attachable via the threaded tubular connection piece 39b increases the ease at which the sections 39a, 39b can be manufactured in comparison to the embodiment of the single piece removable valve 37 exemplified in FIGS. 11a to 11b.

[0049] In another embodiment, the package 2 can be provided with at least one handle 36. The handle 36 can be defined by a hand opening 38 formed as a cut-out within one of the external walls of the carton 4. The carton 4 can be provided with a pair of hand openings 38 on opposing external carton walls so that a user may carry the package 2 with both hands. Alternatively, or additionally, the handle 36 could be formed of a strap-like material, such as plastic, cloth or rope. The handle ends can be attached to edges of opposing external walls such that the body of the handle 36 extends over an end of the package 2, as shown in FIG. 4.

[0050] According to a preferred embodiment, one of the external walls 26 of the carton 4 has a second removable area 40. The second removable area 40 leads into the first cavity 13 thereby forming a bag access opening to expose the bag and provide access thereto for cooling purposes as will be described below.

[0051] The removable areas 24, 40 can have perforations 42 to aid in the removal process. The removable areas 24, 40 have a finger opening 54, one within each external wall 22, 26 thereby allowing the removable areas 24, 40 to be grasped easily, so that the removable areas 24, 40 can be removed by lifting the removable areas 24, 40 and tearing along the perforations 42.

[0052] As shown particularly in FIG. 4, the removable areas 24, 40 comprise a single external layer of cardboard, the inner layers of cardboard beneath the removable areas 24, 40 having respective cut-outs 25, 41 corresponding to the removable areas 24, 40, which allows the removable areas 24, 40 to be easily torn along the perforations 42. The cut-outs 25, 41 are arranged so as to be slightly smaller than the respective removable areas 24, 40, such that the inner walls of the carton 4 support the perforations 42 thereby preventing the removable areas 24, 40 from being inadvertently torn or from collapsing inwardly during transport or handling.

[0053] Additional perforations 43, as exemplified in FIGS. 1 and 2, can be provided in the external layer of cardboard, the perforations 43 extending between the removable areas 24, 40, and recessed hand portion and finger opening 54 respectively. These perforations 43 assist the user to break the external layer of cardboard to allow the bag to be assessed such that the bag can be inserted into a separate dispensing device (not shown) or alternatively the bag can be removed so that the package 2 can be separated for recycling purposes.

[0054] The package 2 can be configured to be used with an apparatus for dispensing liquid 46, as shown in the embodiment of FIGS. 6 and 7. The apparatus 46 has cooling or heating means 50, which is arranged to cool or heat the contents of the bag. The apparatus 46 has a structure 48 for receiving the package thereon. The cooling or heating means 50 has a raised cooling or heating portion 50 which is configured to project into the first cavity 13 of the package 2 when the second removable area 40 has been removed and the package 2 is received on the structure 48, whereby, the bag being filled with liquid 8, conforms to the shape of the raised cooling or heating portion 50 directly contacting and efficiently cooling or heating the contents of the bag. In a preferred embodiment, the raised cooling or heating portion 50 has a dome-like shape. The cut-outs 41 within the inner layers of the carton 2 beneath the further adjacent external wall 26 has a smaller diameter than the removable area 40 to assist in supporting the weight of the package 2 when it is in contact with the raised cooling or heating portion 50.

[0055] The structure 48 is arranged to hold the package 2 such that the spout 10 is spaced above a surface, such as a counter-top, such that a vessel can be conveniently placed beneath the valve 34 to capture the dispensed liquid 8. The structure 48 can have a sloping top surface 49 whereby, when the package 2 is received on said surface 49, the dispensing outlet end of the package 2 is lower than the opposite end such that the contents of the bag settle at the dispensing outlet end thereby assisting the contents to drain from the package 2 without additional manipulation.

[0056] In an example use of the apparatus 46, the user inserts a finger or thumb into the finger openings 54 of the first and second removable areas 24, 40 tearing along the perforations 42 thereby exposing both the spout outer end 18 in the second cavity 20, which is closed by a removable cap 32, and the bag in the first cavity 13. The removable cap 32 can then be replaced by a valve 34. As illustrated in FIG. 5, the user can then dispense liquid 8 directly from the package 2, first grasping the package 2 by a hand opening 38 and a recessed hand portion 44 on an edge of external wall 26, and tipping the package 2 so that the liquid 8 flows from the spout outer end 18 by the action of gravity.

[0057] According to another embodiment of the invention, there is shown an apparatus 56 for dispensing liquid 8, the apparatus 56 having pumping means (not shown) connectable to the package 2 via the dispensing outlet 10 of the package 2. The apparatus 56 has a dispensing outlet 58 for dispensing the drawn liquid 8 fed to it by the pumping means and an enclosure 60 configured to house at least one package 2, the dispensing outlet 58 and pumping means. The enclosure 60 can be arranged with a door 62, the door 62 being openable and closable to allow removal and insertion of the package(s) 2. The at least one package 2 is housed in a lower part of the enclosure 60 and the dispensing outlet 58 is in an upper part of the apparatus 56 to form an upright configuration. Such an upright configuration allows the apparatus 56 to be floor-mountable. In a preferred embodiment, the apparatus 56 can be free-standing.

[0058] In an example use of the apparatus 56, the user easily removes the removable area 24 by inserting fingers into the finger opening 54, grasping and lifting the removable area 24 and tearing along the perforations 42 to expose the spout outer end access area. The pumping means can have a hose (not shown), which can extend from within the enclosure 60, to be inserted into the spout 10 when the removable cap 32 (or removable cap having an integrated valve 35 or attachable valve 34) is detached, to feed the drawn liquid 8 to the dispenser outlet 58 of the apparatus 56 via the pumping means from the bag. The package 2 can then be placed into the enclosure 60 via the door 62. The liquid 8 can be heated or cooled, as desired before dispensing.

[0059] FIG. 9 shows an example blank 64 for a carton 4 formed of a cardboard material, the carton 4 being formed by bending the blank 64 along the fold lines 68 and gluing the flaps 70. The dotted lines represent perforations 42, which define the removable areas 24, 40. The adjacent external wall 22, as illustrated in FIG. 9, has a pair of flanges 72, 74, each flange 72, 74 extending from opposing edges of the adjacent external wall 22. One of the flanges 72 is foldable and has tabs 76 that are securable in the slots 78 of the other flange 74 such that a part of the flange 72 is parallel to and spaced apart from the adjacent external wall 22 thereby defining the second cavity 20. It can be understood by a person skilled in the art that this is an example blank for the carton 4 as described above and many embodiments of this blank can be configured so as to produce such a carton 4.

[0060] While various embodiments of the present invention have been described above, it should be understood that they have been presented by way of example only, and not by way of limitation. It will be apparent to a person skilled in the relevant art that various changes in form and detail can be made therein without departing from the spirit and scope of the invention. Thus, the present invention should not be limited by any of the above described exemplary embodiments.
