Abstract
The present invention minimizes the assembly time of a dispenser head by inserting a rigid seal retaining element. The seal retaining element comes in different configurations thus allowing a variety of compressed gas cartridge dispensing options. Additional features are integrated into a molded dispenser head thus requiring fewer components to accomplish a useable dispenser thus reducing manufacturing costs. Reliance on conformable plastic allows for relaxed dimensional tolerances. This method of making a dispenser head can equally apply to threaded or non-threaded lance housings.
Claims4
