The present invention relates to improvements in the dispensing of foodstuffs from piping bags. The use of piping bags to dispense decorative materials, such as icing, on to surfaces is well known and has been in use for many years. When used in conjunction with a nozzle, such piping bags allow for the dispensing of decorative materials to create messages or patterns. The nozzle can have a variety different shapes and sizes which allow for the ribbon of decorative material to have the desired appearance when expelled from the bag. Existing piping bags are limited in that they typically only have a single compartment in which the decorative material can be placed. The present invention seeks to provide a piping bag and nozzle assembly which allows for the simultaneous and controllable dispensing of two or more decorative materials on to surfaces to create messages or patterns.

1. A piping bag with a nozzle assembly for simultaneous dispensing two or more decorative materials, comprising: a piping bag having two or more compartments, each compartment having a removable nozzle insert with a dispensing aperture, each nozzle insert projecting from an open end of the compartment;a nozzle tip located over the nozzle inserts, said nozzle tip having a proximal end which is operably secured with respect to at least one of the piping bag and nozzle inserts and an outlet configured to dispense a decorative material;wherein at least one of the nozzle inserts has a tongue which projects within the nozzle tip, the tongue, in connection with the nozzle tip, defining separate passageways from each of the two or more compartments through the nozzle assembly until at or in close proximity to the outlet of the nozzle tip; anda securing ring reversibly connecting the nozzle tip and nozzle inserts to form the nozzle assembly;wherein the nozzle tip has a plurality of grooves extending from the proximal end of the nozzle tip to the outlet of the nozzle tip within an inside surface of the nozzle tip;wherein the at least one tongue has edges which abut against the inside surface of the nozzle tip, the edges of the at least one tongue being shaped to slide within the grooves of the nozzle tip to provide correct alignment of the at least one tongue within the nozzle tip along a length of the tongue from the proximal end of the nozzle tip to the outlet of the nozzle tip to enable continuity of separation between said two or more separate passageways while dispensing decorative materials from each of the two or more compartments. 2. The assembly of claim 1 wherein there are two compartments. 3. The assembly of claim 1 wherein there are three compartments. 4. The assembly of claim 1 wherein there are four compartments. 5. The assembly of claim 1, wherein there are two compartments and wherein the nozzle inserts have a tapered flat wall and an arcuate wall extending from one side of the tapered flat wall to the other side of the tapered flat wall. 6. The assembly of claim 1, wherein there are three compartments and wherein the nozzle inserts comprise tri-sectored components and have tapered flat radial walls and an arcuate external wall extending from first and second radial walls. 7. The assembly of claim 1, wherein there are four compartments and wherein the nozzle inserts comprise four-sectored components and have tapered flat radial walls and an arcuate external wall extending from first and second radial walls. 8. The assembly of claim 1, wherein when brought in proximity the nozzle inserts form an external screw thread on to which the securing ring is fastened. 9. The assembly of claim 1, wherein the securing ring is a ring having an internal screw thread. 10. The assembly of claim 1, wherein the outlet of the nozzle tip is selected from a circle, a rectangle, an ellipse, a star shape or a ring. 11. The assembly of claim 1, wherein the nozzle has a bridging member at the nozzle tip and the at least one tongue-like nozzle insert abuts or overlaps with said bridging member. 12. A kit for simultaneous dispensing two or more decorative materials, comprising: a piping bag having two or more compartments, each compartment having a removable nozzle insert with a dispensing aperture, each nozzle insert projecting from an open end of the compartment;a nozzle tip adapted to be located over the nozzle inserts, said nozzle tip having a proximal end which is operably secured with respect to at least one of the piping bag and nozzle inserts and an outlet configured to dispense a decorative material;wherein at least one of the nozzle inserts has a tongue which projects within the nozzle tip, the tongue, in connection with the nozzle tip, defining separate passageways from each of the two or more compartments through the nozzle assembly until at or in close proximity to the outlet of the nozzle tip; anda securing ring for reversibly connecting the nozzle tip and nozzle inserts to form a nozzle assembly;wherein the nozzle tip has a plurality of grooves extending from the proximal end of the nozzle tip to the outlet of the nozzle tip within an inside surface of the nozzle tip; andwherein the at least one tongue has edges which abut against the inside surface of the nozzle tip, the edges of the at least one tongue being shaped to slide within the grooves of the nozzle tip to provide correct alignment of the at least one tongue within the nozzle tip along a length of the tongue from the proximal end of the nozzle tip to the outlet of the nozzle tip to enable continuity of separation between said two or more separate passageways while dispensing decorative materials from each of the two or more compartments. 13. A nozzle assembly for simultaneous dispensing two or more decorative materials, comprising: two or more nozzle inserts, each of the two or more nozzle inserts having a dispensing aperture, at least one of the nozzle inserts including a tongue extending beyond the dispensing aperture;a nozzle tip adapted to be located over the two or more nozzle inserts, the nozzle tip having two or more grooves to receive edges of the tongue of the at least one of the nozzle inserts along a length of the tongue of the at least one of the nozzle inserts; anda securing ring for reversibly connecting the nozzle tip and the two or more nozzle inserts.
