ABSTRACT:
The writing implement comprises a sleeve-shaped housing (1) in which an inner sleeve (7) is disposed includes a writing element (2). At the tip-side end of the inner sleeve (7) is disposed a hermetic closure portion (8) which comprises a plurality of segments (34) which are biassed radially outwardly and which in the closure position (FIG. 7 ), bear on each other forming a seal beyond the nib (26) and which are provided with sealing bead segments (23) which also bear on each other forming a seal behind the tip of the writing element (26) and which bear on the tip segment (4) of the writing element (2), so that the nib portion (26) of the writing element is closed in an overall hermetically sealing chamber (6). The writing implement uses a mechanism which facilitates, while pressing the actuating element (11), the premature opening of the closure element (8) before the exit of the writing element (2) therefore avoiding contact with the nib (26 ). The co-ordination between closure portion (8) and writing element (2) can be reached by several means.
