摘要

The invention relates to a reloadable marker implement (1), comprising: a tubular body (4) containing a supply unit (8) therein; a writing tip (2); a removable end piece (10) which seals a rear opening (6) of the tubular body (4), thus enabling the removal of the supply unit, and which has an inner portion (11) inserted into the tubular body in a loaded configuration of the implement; and an outer portion (12) provided with a profiled portion (14) for rotatably engaging with a cap (3) or a fitted key. The inner surface (9) of the tubular body has a cam system (24a, 24b) on the rear-opening side, the inner portion having a projection (30) forming a cam follower for guiding the removable end piece during the removal or fitting thereof. The rear opening is sealingly closed through the use of raised sealing areas (31, 32, 41, 42) located behind the cam system.
