Definitions

• the invention relates to a diffuser for a pressurized container provided with a valve, in particular for an aerosol generator, and more particularly a diffuser in several assembled parts.
• a diffuser is made up of two main parts with distinct functions injected into one material. These two parts are the outlet duct, the functions of which are to lead the product contained in the pressure vessel from the valve and to dispense this product, and the base body which makes it possible to protect the outlet duct and which includes elements to activate the outlet duct to cause the product to exit.
• the diffuser can be molded in one piece or have parts injected in one material, optionally in two different colors, and mechanically snapped together. So depending on the container, the commercial distributor of the final article, and the product contained in the container, the diffuser modeling must be completely redesigned for each new variation, and the production lines readjusted. As a result, these additional modeling and production costs are reflected in the cost of each diffuser produced. Thus, there is a need for a diffuser whose variations have a lower cost.
• Diffusers already exist, the parts of which, before assembly, are initially separate and then assembled, for example mechanically, by gluing or thermal welding, or produced by bi-material injection. Only these diffusers require that their different parts be completely redesigned and the production chains readjusted for each possible variation of the diffuser. All the additional modeling and manufacturing costs, despite the possibility of using separately manufactured parts for different parts of the diffuser, are not significantly reduced enough. Therefore, it is necessary to have a diffuser that can be adapted to different variations more easily to limit additional costs.
