Abstract

Abstract A golf club head containing a filling orifice (6) designed for filling an interior cavity (4) with a foaming material (5). The orifice (6) is sealed with an element (7) allowing selective permeability and comprising at least one wall (71) forming the interface between the interior cavity (4) and the outside and through which only gas molecules can excape from the interior cavity (4) to the outside under the pressure exerted by the volume of the foaming material during injection and during its expansion after injection.
