METHOD OF MANUFACTURING AN INJECTED DIFFUSING PART FOR ODORS AND PART OBTAINED BY THIS METHOD

摘要

The present invention relates to a method of making parts manufactured by a bi-substance type injection, economically and giving these parts effective and controllable qualities of odor emitters. The method of the invention is characterized in that uses for the first thermoplastic substance forming the skin (31) of part (30), a substance that is permeable to odors and containing filtering means, and for the second thermoplastic substance forming the core (32) of the part surrounded by said skin, a substance that is permeable to odors and including at least one substance (33) emitting odors, whose diffusion is slowed down and controlled by filtering means (34) planned in the skin (31).
