Abstract

A nozzle part for conveying a viscous fluid, comprising at least one wall defining a passageway, the passageway having an outlet remote from an inlet, the passageway having a larger cross sectional area at or adjacent its inlet compared to a lower cross sectional area at or adjacent its outlet, wherein at least a part of the wall is provided with at least one indicator to differentiate a part of the wall from the remainder of the wall.

1 . A nozzle part for conveying a viscous fluid, comprising:
 at least one wall defining a passageway, the passageway having an outlet remote from an inlet,   the passageway having a larger cross sectional area at or adjacent its inlet compared to a lower cross sectional area at or adjacent its outlet,   
       wherein at least a part of the wall is provided with at least one indicator to differentiate a part of the wall from the remainder of the wall. 
     
     
         2 . The nozzle part according to  claim 1 , wherein the indicator comprises at least one of:
 a marking on a surface of the wall;   a recess or groove in the wall; or   an area of weakness in the wall.   
     
     
         3 . The nozzle part according to  claim 1 , wherein the indicator extends in a direction perpendicular to a longitudinal axis of the passageway. 
     
     
         4 . The nozzle part according to  claim 1 , wherein the indicator extends around the perimeter of the wall. 
     
     
         5 . The nozzle part according to  claim 1 , wherein the indicator is provided on an outer surface of the wall. 
     
     
         6 . The nozzle part according to  claim 1 , wherein the indicator is provided on an inner surface of the wall. 
     
     
         7 . The nozzle part according to  claim 2 , wherein the at least one indicator is a plurality of indicators disposed in order of weakness relative to the outlet. 
     
     
         8 . The nozzle part according to  claim 7 , wherein the at least one indicator is a plurality of indicators which are progressively resistant to breakage in a direction away from the outlet. 
     
     
         9 . The nozzle part according to  claim 1 , wherein the indicator is in the form of a step defining a corner. 
     
     
         10 . The nozzle part according to  claim 1 , wherein the indicator is in the form of an area of reduced wall thickness. 
     
     
         11 . The nozzle part according to  claim 1 , wherein the nozzle is provided with a socket formation at or adjacent its inlet. 
     
     
         12 . The nozzle part according to  claim 11 , wherein the socket formation is part-spherical. 
     
     
         13 . A connector for engagement with a delivery nozzle of a storage tube, the connector comprising:
 a hollow outer shell; and   a resiliently deformable inner sleeve fitted within the outer shell, wherein the resiliently deformable inner sleeve is configured to receive at least part of the delivery nozzle of the storage tube such that the resiliently deformable inner sleeve at least partially deforms to hold the delivery nozzle in engagement with the connector.   
     
     
         14 . The connector according to  claim 13 , wherein the hollow outer shell defines a passageway in which the resiliently deformable inner sleeve is received. 
     
     
         15 . The connector according to  claim 14 , wherein the connector is configured such that an end of the delivery nozzle including an aperture is located beyond the confines of the resiliently deformable inner sleeve when the delivery nozzle is at least partially received by the resiliently deformable inner sleeve 
     
     
         16 . The connector according to  claim 13 , wherein the resiliently deformable inner sleeve is supported by the hollow outer shell. 
     
     
         17 . The connector according to  claim 13 , wherein the connector defines a passageway for the flow of a viscous liquid from the delivery nozzle. 
     
     
         18 . A nozzle assembly comprising a nozzle part coupled to a connector for conveying a viscous fluid, the nozzle part comprising:
 at least one wall defining a passageway, the passageway having an outlet remote from an inlet,   the passageway having a larger cross sectional area at or adjacent its inlet compared to a lower cross sectional area at or adjacent its outlet, wherein at least a part of the wall is provided with at least one indicator to differentiate a part of the wall from the remainder of the wall; and the connector being for engagement with a delivery nozzle of a storage tube, the connector comprising:   a hollow outer shell; and   a resiliently deformable inner sleeve fitted within the outer shell, wherein the resiliently deformable inner sleeve is configured to receive at least part of the delivery nozzle of the storage tube such that the resiliently deformable inner sleeve at least partially deforms to hold the delivery nozzle in engagement with the connector.   
     
     
         19 . The nozzle assembly according to  claim 18  further comprising an extender part configured to couple the nozzle part to the connector.
