The invention is a nozzle assembly (3, 20) with a re-useable break off cap (20) for dispensing a product from a container (1). On a dispensing end (5) of the nozzle (3) a break-off cap (20) is integrally formed thereon and closes off the dispensing end (5) of the nozzle (3). The break-off cap (20) is removable by breaking a frangible connection (22) between the nozzle (3) and the break-off cap (20). Removing the break-off cap opens the dispensing end (5) of the nozzle (3) thereby allowing product to be dispensed through the nozzle (3). The break-off cap (20) removed from the nozzle (3) can then be re-engaged with the nozzle (3) to close off the dispensing end (5) thereby preventing further product from being dispensed. The cap can be attached to or removed from the nozzle (3) as often as a user requires. The invention also includes packaging which includes a tray (111) or pouch into which the nozzle assembly (3, 20) and container (1) can be inserted. A flexible resealable peel-off cover (110) is provided on each tray (111) to allow a user to resealably open and close the tray (111). The resealable tray (111) can be provided either singly or as a series of trays.
