Piping bag and nozzle

摘要

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.

主权项

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; and a 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.
