Patent number: 6042290Abstract: A writing tool provided with a valve construction in which a rotary body embraced in a ball house at the extreme end of a tip is urged forward by means of a coiled spring inserted into the tip to be partly projected, in which state the rotary body comes in contact with an inwardly directed extreme end edge to prevent ink or an applying liquid from flowing out, and when in use, the rotary body partly projecting from the extreme end of the tip presses a paper surface to retreat (immerse) the rotary body against the force of the coiled spring to transfer the ink or the applying liquid onto the paper, wherein the coiled spring is formed to be shorter than the tip.Type: GrantFiled: March 5, 1997Date of Patent: March 28, 2000Assignee: Zebra Co., Ltd.Inventors: Shinichi Ishikawa, Matsuhei Toyama, Morio Akiyama

Patent number: 6010264Abstract: A method and apparatus for applying various topical solutions, the ends of which are able to either spray, roll or sponge on (or a combination of the aforementioned) various topical solutions applied to a living body. The sprayer enables the user to spray on various liquid products. The roller ball enables the user to apply topical solutions with a massage effect. The sponge or sponges enable the user to apply a wide range of solutions while achieving a cleansing effect. The present invention greatly improves upon the functionality and appearance of the product known as Reach-It of DES 285,172 and utility U.S. Pat. No. 4,571,106.Type: GrantFiled: March 6, 1998Date of Patent: January 4, 2000Assignee: Tom FreemanInventors: Richard Scuderi, Thomas J. Freeman

Patent number: 5988921Abstract: A pen for left handed persons includes a writing tip having a cone including a bend proximate the socket for the ballpoint to form an angle in the cone. The pen resembles a standard tubular shaped body into which a tubular shaped ink cartridge, connected to the writing tip, is removably inserted. The tip protrudes from one end of the body but is dimensioned so that it does not interfere with placement of a standard pen cap thereon. The tip of the pen includes a tubular shank adapted to fit into an integral sleeve located at the writing end of the body. A second embodiment bends the body of the pen to achieve the desired angle, enabling the use of a standard removable pen tip.Type: GrantFiled: March 11, 1999Date of Patent: November 23, 1999Inventor: Michael S. Medhin

Patent number: 5984559Abstract: A ballpoint pen refill which can be applied to a retractable ballpoint pen is provided. An ink 2 endowed with a thixotropic property and an ink follower 3 at the rear of this ink are contained within an ink tube 1 comprising a tip holder member 9 and an ink member 10. A ball 6 is held in a front end aperture 9a thereof. A ballpoint pen tip 4 having an inner reshaped surface 4f of a front end rim 4b that is formed into a spherical surface in the shape of the ball is fitted therein. A coil spring 7 that always presses the ball onto the inner reshaped surface is provided with a movable member 8 between the spring and ball. A stopper 5 provided with a ventilation means is fitted into a rear end of the ink tube. A partition portion 9g having an ink-flow passageway for restricting the amount of ink that flows and a rear end surface 9c is formed in an engagement portion 9d of the tip holder member 9 that is fitted in the ink member 10.Type: GrantFiled: August 18, 1997Date of Patent: November 16, 1999Assignee: Kabushiki Kaisha PilotInventors: Toshikazu Shiobara, Kazuhiko Sasaki, Teruaki Fukasawa

Patent number: 5938362Abstract: In a writing implement for ink, having a nib and having a shaft (3) a lamination system for holding or emitting ink is arranged, which lamination system has an ink feed channel (18) which runs in a longitudinally extending lamination carrier (10). Protruding from the lamination carrier (10) is a group of transversely arranged and mutually spaced laminations (24), between which laminations (24) there is a capillary gap (20) between the side of the lamination carrier (10) having the open side of the ink feed channel (18) and the inner wall (22) of the shaft (3). In a first region (34) which is located in the region of the open side of the ink feed channel (18), the laminations (24) each extend up to the inner wall (22) of the shaft (3). In a second region (36), which faces away from the first region (34) and extends over at least 80% of the circumference of the laminations (24), a distance, which prevents a capillary effect, from the inner wall (22) of the shaft (3), is maintained.Type: GrantFiled: March 2, 1998Date of Patent: August 17, 1999Assignee: Rotring International GmbH & Co. KGInventor: Bernd Bastiansen
