Definitions

• the present invention relates to writing instruments.
• a writing instrument comprising, on the one hand, a body provided with a writing block and a reservoir holder device, this reservoir being optionally interchangeable, and on the other hand, a cap. removable which, in closed position, protects the writing block.
• the present invention provides a writing instrument comprising the advantages of each of the above writing instruments, without their drawbacks. More specifically, it proposes a writing instrument in which it is not necessary to remove the cap to separate the body and the writing block, or to hold this writing block in the hand to ensure this separation. In addition, in this writing instrument, when this separation is carried out, there is then access to the entire tank-holding device.
• the subject of the invention is a writing instrument comprising, on the one hand, a body, a writing block, a tank-holding device, a rotary system enabling the locking of at least the tank-holder device on the body and, on the other hand, a removable cap, which, in the closed position, protects the writing block,
• this instrument being characterized in that the internal surface of the cap and the external surface of the tank holder device each comprise at least one profile part substantially complementary to each other, which cooperate by nesting when said cap is disposed on the body in the closed position and whose shape is such that it allows the drive in rotation of said tank-carrying device by said cap.
• Figure 1 is a longitudinal section of an embodiment of a writing instrument according to the present invention
• Figure 2 is a section along line II-II of the cap of Figure 1.
• the writing instrument shown in the drawings is a fountain pen, which consists of a body 1 and a cap 2.
• a support 3 is screwed inside the body 1 and carries, firstly, an ink reservoir 4 constituted by a cartridge, secondly, a part 7 made of an elastically defo ⁇ nable material, comprising an annular bulge 7a, and , thirdly, a writing block comprising in particular a tip 5 and a feather 6.
• the support 3 is held in position relative to the body 1 by the cooperation of a thread 17 and an internal shoulder 11 of said body 1.
• An elastic piece 8 identical to the elastic piece 7 and comprising a bulge 8a is located at the end of the body 1.
• the nozzle 5 has, at its periphery, a number of longitudinal grooves 9 and projecting parts 10 separating said grooves.
• the cap 2 ends in a zone 12 with extra thickness and by a recessed end 13, which has an inner circular groove 14, intended to cooperate with the bulged parts 7a and 8a of the elastic parts 7 and 8, to maintain the cap on the body, either in writing position or in closed position.
• the zone 12 comprises a series of longitudinal grooves 15 and of projecting parts 16, which correspond to the parts 10 and to the grooves 9 of the nozzle 5, so that. when the cap 2 is disposed on the body 1 in the closed position, there is an angular joining of the two parts. It then suffices to rotate the cap 2 to unscrew the endpiece 5 carrying the cartridge 4 and thus remove it from the body 1.
• this disassembly which gives access to the entire tank-holder device, can it be carried out by simply holding the body and the cap and therefore without it being necessary to hold the pen-holder block in hand.
• the grooves and the protruding parts of the cap and of the end-piece 5 could be replaced by simple longitudinal flats or other technical equivalents ensuring the joining in rotation of the end-piece and the end-cap.
