Claims:
AMENDED CLAIMS

received by the International Bureau on 19 February 2019 (19.02.2019)

1 . A mould including: - a separator base; and walls extending from opposing sides of the base which, together with the base, are arranged to define a plurality of moulding zones for receiving liquid to be moulded therein; and slits defined in the walls of the moulding zones for facilitating bending of the base and walls during demoulding of moulded articles from the moulding zones.

2. A mould as claimed in claim 1 wherein the walls taper in thickness from the separator base towards their respective free edge regions.

3. A mould as claimed in claim 1 or 2 wherein the walls are arranged at an angle relative to the separator base so as to define moulding zones which taper from the free edge regions of the walls towards the base.

4. A mould as claimed in any one or more of the preceding claims wherein the separator base and walls are manufactured from any suitable synthetic plastics material having non-stick and temperature resistant properties.

5. A mould as claimed in any one or more of the preceding claims wherein the separator base and walls are manufactured from any suitable combination of synthetic plastics and metallic materials.

6. A mould as claimed in any one or more of the preceding claims wherein communication zones are defined in the walls for allowing fluid communication between adjacent moulding zones.

7. A mould as claimed in any one or more of the preceding claims wherein communication zones are defined in the base for allowing fluid communication between moulding zones on either side of the base. 8. A mould as claimed in claim 6 or 7 wherein the communication zones are in the form of any one or more of the group including an aperture, notch, hole, slit and channel for allowing fluid to pass therethrough and between moulding zones during filling thereof with liquid to be moulded.

9. A mould as claimed in any one or more of the preceding claims wherein a peripheral region of the walls is profiled to facilitate receipt by and removal from any suitable conventional container.

10. A mould as claimed in claim 9 wherein the peripheral region has a generally tapered profile for facilitating removal thereof from the container after completion of the moulding process.

1 1 . A mould as claimed in any one or more of the preceding claims which includes a folding zone for allowing the base to be folded in a concertina fashion to allow free edge regions of the walls to be arranged in register with each other so as to form enlarged moulding zones therebetween.

12. A mould as claimed in any one or more of the preceding claims wherein free edge regions of the walls are sized, shaped and configured to facilitate in-register stacking of a plurality of moulds so as to form enlarged moulding zones therebetween.

13. A mould as claimed in any one or more of the preceding claims wherein a carrier handle is provided.

25

14. A moulding assembly which includes a plurality of moulds as claimed in any one or more of the preceding claims which are capable of being arranged in a stacked or side-by-side configuration to allow free edge regions of the walls of opposing moulding zones to be arranged in register with each other.

15. A moulding assembly as claimed in claim 14 wherein a connecting member is provided for allowing interconnection between adjacent moulds.

16. A moulding assembly as claimed in claim 15 wherein the connecting member is configured to allow relative displacement of the moulds between a moulding condition and a de-moulding condition.

17. A moulding assembly as claimed in claim 14 or 15 wherein the connecting member is in the form of a flexible web which extends between and interconnects opposing edge regions of the moulds to allow displacement of the moulds in a concertina fashion.

18. A moulding assembly as claimed in claim 17 wherein communication zones are defined in the web to facilitate fluid flow therethrough.

19. A moulding assembly as claimed in claims 15 or 16 wherein the connecting member is in the form of complemental male and female engaging formations which extend from and are defined in respective opposing sides of the moulds for facilitating stacked interconnection of the moulds.

20. A moulding assembly as claimed in claim 19 wherein the connecting member allows the walls of adjacent moulds to be interposed each other and to extend substantially between the bases of opposing moulds.
