DETAILED DESCRIPTION OF THE INVENTION

[0046] In a first embodiment of the invention, as shown in FIGS. 1 to 5, reference numeral 10 refers generally to a mould in accordance with the present invention. The mould 10 includes a separator base 12 and walls 14 extending from opposing sides 16.1 and 16.2 of the base 12 which, together with the base 12, are arranged to define a plurality of moulding zones 18 for receiving liquid (not shown) to be moulded therein.

[0047] The base 12 has a generally planar form and corresponds to any conventional shape. In particular, the separator base 12 has any suitable geometric shape of the group including circular, ovoid, rectangular, square and triangular when viewed in plan, typically being generally rectangular as shown in FIGS. 1 to 5.

[0048] The walls 14 are interconnected at their opposing edge regions 20 so as to define discrete moulding zones 18 therebetween. The walls 14 and base 12 are configured to form moulding zones 18 of any suitable geometric shape of the group including cuboidal, parallelepipedal, conical, frusto-conical, semi-spherical, wedge and pyramidal, typically being generally parallelepipedal as shown in FIGS. 1 to 5.

[0049] For example, walls 14 extending from a rectangular base 12 defines generally parallelepipedal or cuboidal moulding zones 20, as shown in FIGS. 1 to 5, and walls 214 extending from a circular base 146 typically defines generally wedge-shaped moulding zones 218 as shown in FIGS. 6 to 9.

[0050] The separator base 12 and walls 14 are integrally formed. The base 12 and walls 14 have a thickness in the range of 0.5 mm to 4 mm, typically being 2 mm. The base 12 and walls 14 are manufactured from any suitable synthetic plastics material having non-stick and temperature resistant properties, typically being silicone. Although not shown, the base 12 and walls 14 can be manufactured from any suitable combination of synthetic plastics or metallic materials, such as silicone and aluminium, so as to improve a moulding or freezing rate of liquid contained in the moulding zones 18 in operation.

[0051] Communication zones 22 are defined in the walls 14 for allowing fluid communication between adjacent moulding zones 18. Further communication zones 22 are defined in the base 12 for allowing fluid communication between moulding zones 18 on either side of the base 12 during filling thereof with liquid to be moulded. The communication zones 22 are configured to extend between the respective moulding zones 18 for allowing fluid to pass therebetween. The communication zones 22 are in the form of any one or more of the group including an aperture, notch, slit, hole and channel for allowing fluid to pass therethrough and between respective moulding zones 18 during filling thereof with liquid to be moulded. More particularly and as shown in the drawings, the communication zones 22 defined in the base 12 are typically in the form of generally circular holes 24 and the communication zones 22 defined in the walls 14 are typically in the form of slits 26. The slits 26 are further configured to facilitate bending of the separator base 12 and walls 14 during removal of moulded articles (not shown) from the moulding zones 18.

[0052] A peripheral region 28 of the walls 14 are profiled to facilitate receipt by and removal from any suitable conventional container 30. In particular, the peripheral region has a generally tapered profile for facilitating removal thereof from the container after completion of the moulding process. The peripheral region typically tapers from an opening or filling end region 32 of the container 30 towards a base region 33 thereof. The mould 10 is of generally parallelepipedal shape.

[0053] The container 30 can be in the form of a conventional 2-litre ice-creme container. An inner compartment 34 of the container 30 is typically tapered according to a tapered shape of the mould 10 so as to allow the complementary fit therebetween. The tapered shape of the inner compartment 34 additionally facilitates the removal of the mould 10 therefrom when liquid received within the moulding zones 18 is moulded or frozen.

[0054] A closure member in the form of a lid 36 is provided for closing and sealing the container 30 in use. The lid 36 is typically used when a user wishes to produce ice whilst transporting the mould 10.

[0055] Referring particularly to FIGS. 4a to 4c, reference numeral 90 refers generally to a mould forming kit in accordance with the invention. The mould forming kit 82 includes a mould 10 as hereinbefore described and a container 30 as hereinbefore described.

[0056] Referring now to FIGS. 5a to 5c, reference numerals 38, 40 and 42, refer generally to moulding assemblies which include a plurality of moulds 10.1, 10.2, and 10.3, respectively, to be arranged in a side-by-side configuration.

[0060] Referring now to a third embodiment of the invention, as shown in FIGS. 7 to 9, reference numeral 244 refers generally to a moulding assembly including a plurality of moulds 210 having generally circular bases 246. In this embodiment, the plurality of generally circular moulds 210 are arranged in a stacked in configuration to allow free edge regions 215 of the walls 214 of opposing moulding zones 218.1 and 218.2 to be arranged in register with each other so as to form a plurality of moulding zones 248 therebetween when the moulds 210 are arranged in an operative stacked moulding condition.

[0061] Further in this embodiment, and as shown in FIG. 7b and more clearly in FIG. 8, a connecting member in the form of complemental male and female engaging formations 250.1 and 250.2, respectively, extend from and are defined in respective opposing sides 216 of the moulds 210 for facilitating stacked interconnection of the moulds 210. In particular, the male and female formations 250.1 and 250.2 are in the form of alternating protrusions 252 and recesses 254, typically being located towards a central region 256 of the opposing sides 216 of the bases 246. More particularly, the stacked moulds 210 define top, intermediate and bottom moulds 258.1, 258.2, 258.3, respectively, the top mould 258.1 typically having the male formation 250.1 defined on an operative under side 216.1 thereof, the intermediate mould 258.2 typically having the male and female formations 250.1 and 250.2 defined on operative under and top sides 216 thereof, respectively, and the bottom mould 258.3 typically having the female formation 250.2 defined on an operative top side 216.2 thereof. As most clearly shown in FIG. 7a, the male and female formations 250.1 and 250.2 are configured to allow walls 214 of adjacent moulds 210 to be interposed each other and to extend substantially between bases 246 of opposing moulds 210.

[0062] As shown in FIG. 9, the moulding assembly 244 is sized, shaped and configured to be received complementally by a cylindrical container 230 in use. In particular, the moulding assembly 244 is of generally cylindrical shape, typically as a result of the stacked circular moulds 210.

[0063] The container 230 can be in the form of a conventional 1-litre yoghurt container.

[0064] A closure member in the form of a lid 236 is provided for closing and sealing the container 230 in use. The lid 236 is typically used when a user wishes to produce ice whilst transporting the mould 210.

[0065] Referring particularly to FIGS. 9a to 9c, reference numeral 290 refers generally to a mould forming kit in accordance with the invention. The mould forming kit 290 includes a moulding assembly 210 as hereinbefore described and a container 230 as hereinbefore described.

[0066] The walls 114 and 214 extending from either side 116 and 216 of the bases 146 and 246 of the moulds 110 and 210 are interconnected at a generally central region 156 and 256 of the circular bases 146 and 246 and typically extend radially away therefrom so as to form discrete, generally wedge-shaped moulding zones 118 and 218 therebetween.

[0067] In use, a user typically places the moulding assembly 244 one mould 210 at a time inside the container 230 into a stacked configuration and proceeds to fill the container 230 with water. The user typically rotates each mould 210 once received in the container 230 so as to allow walls 214 of adjacent moulds 210 to be interposed each other and to extend substantially between bases 216 of opposing moulds 210. Upon entry of water into the moulding zones 218, air is forced out via the communication zones 222 and allows the water to be received in each of the moulding zones 218 in the mould 210. It is at this point that the user would typically put the lid 236 onto the container 230, thereby preventing any spillage of water whilst placing the mould 210 into a freezer. Once the water inside the mould 210 is frozen, the user removes the moulding assembly 244 from the container 230. The user then bumps the mould 210 against a hard surface a sufficient number of times to break up the ice between the moulding zones 218. The user then twists and bends the moulding assembly 244 in order to release the ice blocks from the moulding zones 218. The user typically does this action having a larger container or holder placed beneath the mould 210 so that the ice blocks are able to fall therein.

[0068] Referring now to a fourth embodiment of the invention, as shown in FIGS. 10 and 11, reference numeral 360 refers generally to a moulding assembly having a pair of generally rectangular moulds 310. The generally rectangular moulds 310 are arranged so as to define a plurality of enlarged moulding zones 348 therebetween when the plurality of moulds 310 are arranged in an operative moulding condition wherein bases 362 are arranged such that walls 314 of opposing moulding zones 318.1 and 318.2 are arranged in register with each other so as to form enlarged moulding zones 348 as most clearly shown in FIG. 11.
