Abstract:
1. A method for manufacturing an elongate nasal spray head, said elongate nasal spray head including a spray orifice and being formed of only two parts, an external part forming the head, and an internal part forming an insert that is inserted through the inside of the elongate nasal spray head, thus forming an internal nozzle that cannot be expelled out of said elongate nasal spray head during dispensing of a spray through said spray orifice, said method comprising: forming in a manufacturing machine a hollow cavity comprising an inner shape that is complementary to an outer shape of the elongate nasal spray head; forming in the manufacturing machine a cavity insert from a pin by: providing a first projection on an end of the pin that has a shape complementary to a shape of a spray chamber of the elongate nasal spray head; providing a second projection on the end of the pin that has a shape complementary to a shape of at least one non-radial spray channel; providing a third projection on the end of the pin that has a shape complementary to said spray orifice of the elongate nasal spray head; placing the pin in the hollow cavity; forming the elongate nasal spray head by injecting material into a space formed in the manufacturing machine between the hollow cavity and the pin; securing the third projection that corresponds with the spray orifice to the pin by a removable needle.
