Water reservoir for a steam iron and method for producing such a reservoir

An iron reservoir board comprising a lower half-shell (11) having at least one annular piece in relief (23, 33) and an upper half-shell (12) having at least one annular piece in relief (24, 34) provided for nest in and / or above the annular formation (23, 33) corresponding to the lower half-shell (11), characterized in that at least one (24, 34) of the conformations (23, 33; 24, 34) is formed with a coating fixed irreversibly and acting as a seal. The invention also relates to a method for producing an iron container board characterized in that the or one of the coverings acting as sealing joint (25, 35) is obtained by overmolding on the or one annular formations (24, 34), or with one (12) of the half shells by bi-injection molding.
