Abstract: A longitudinal groove which allows a number of annular grooves formed on the outer peripheral surface of an ink storage body to communicate with an ink chamber is cut halfway into the thickness of a flange formed at the rear part of the ink storage body. An outer part of the longitudinal groove cut into the flange is made to communicate with a passage which is defined by a cutout formed on the periphery of the flange and the inner wall of the barrel cylinder so that this passage establishes communication between the longitudinal groove and the ink chamber.

Abstract: A multiplex writing implement of the invention has a multiple number of writing elements, including at least one ball-point pen element which is filled up with a thixotropic water-soluble or low-viscosity oil-based ball-point ink. The ink reserving portion of the ink reservoir of the ball-point pen element is non-flexible and has a relatively large cross-section. A portion for jointing the point assembly with the ink reserving portion is formed so that the element can readily be deflected transversely with respect to the axial direction. The writing tip portions of these writing elements can selectively be projected from and retracted into the barrel front. This multiplex writing implement is able to create line traces with thick line density without causing any blobbing of ink or ink starving. It is also possible to prevent accidental ink leakage. That is, ink can be prevented from staining the barrel cylinder, user's hands, clothes etc.

Abstract: An ink conducting core for supplying ink from an ink container to a pen point is formed with an exposing recess in the vicinity of a connecting portion of the ink conducting core with a middle core. With this, even when outside impact etc. causes air bubbles to enter the ink conducting core, the bubbles may be ejected readily through the exposing recess whereby smooth ink supply can be secured all the time. An annular groove and a small diameter portion is provided in the rear part of an ink conducting core. An ink retainer having a through-hole through which the ink conducting core is fitted is constructed such that the through-hole has a small diameter portion in the rear end thereof. The ink conducting core is fitted to the ink retainer with the side walls of the annular groove engaging the small diameter portion in the rear end of the through-hole. As a result, it is possible to securely restrict back-and-forth movement of the ink conducting core due to impact etc.

Abstract: A liquid applicator includes: an applicator portion provided at the front end of a barrel; a barrel joint having an approximately cylindrical shape, fitted into the rear of the barrel; and a pushing mechanism having a piston for pushing the liquid, accommodated inside the barrel joint. In this pushing mechanism, as a rotary handle is turned, a threaded shaft together with a delivering member rotates so as to move itself forwards by means of screw engagement with a threaded piece fixed to the barrel joint and thereby move the piston in the same direction. A liquid contained in front of the piston is delivered toward the applicator portion, thus the applicator portion is impregnated with the liquid.
