Patent number: 8348540Abstract: A writing instrument that includes an ink reservoir and a writing tip fluidly connected to the reservoir and through which the ink comes out during use of the instrument. The reservoir contains, in addition to the ink, grains that are separate and that may have angles and sharp edges of dimensions that are significant relative to an apparent dimension (d) of the grains.Type: GrantFiled: January 12, 2007Date of Patent: January 8, 2013Assignee: Societe BICInventors: Vincent Bedhome, Didier Lange, Franck Rolion

Patent number: 8104983Abstract: A writing instrument, which has an inner and outer writing element with separate writing medium reservoirs. The writing elements are coaxially mounted in an outer barrel and axially moveable with respect to one another. A driving mechanism may be actuated to allow a user to selectively extend one writing element. The inner and outer writing elements may have an inner sleeve therebetween to improve, for instance, rigidity of the outer writing element and to prevent contamination of the writing medium reservoirs. An outer sleeve may also be provided over the outer writing element. The outer sleeve can function to hold various components of the outer writing element together, and to allow for clean and easy refill of the outer writing element, especially when the outer writing element is a nib-type writing element with a filler-type reservoir. The writing instrument is designed so that a user can replace the inner and/or outer writing elements when their respective writing medium have been expended.Type: GrantFiled: November 11, 2003Date of Patent: January 31, 2012Assignee: Societe BicInventors: Vincent Bedhome, Kenneth R. Cooper, David Anthony Edgerley, Douglas Hungerford, Didier Lange, Robert Edward Matthews, Franck Rolion, Anthony Wlodarczyk

Patent number: 8096725Abstract: A writing implement that includes an ink reservoir, a writing tip fluidically connected to the reservoir and through which the ink emerges during a use of the implement, and a reservoir-venting device that includes a cavity in communication with the reservoir and with an orifice open to the outside of the implement. The cavity is suitable for absorbing an overflow of ink, characterized in that the cavity is filled with separate grains having angles and sharp edges having dimensions that are significant compared with an apparent dimension d of the grains.Type: GrantFiled: January 12, 2007Date of Patent: January 17, 2012Assignee: Societe BICInventors: Vincent Bedhome, Didier Lange, Franck Rolion

Patent number: 7470079Abstract: A writing instrument having a body, a main reservoir containing ink and housed in said body, a writing head projecting from the front part of said body, and a capillary connector for transferring ink from the main reservoir to the writing head. The instrument has an auxiliary reservoir containing an ink carrier liquid, and an actuator for releasing said liquid from the auxiliary reservoir so that said liquid flows into the main reservoir and expels the ink towards the connector. The carrier liquid contains the ink solvent, in particular water in the case of a water-based ink, and preferably contains all or any of the components of the ink in the main reservoir, whereby the original writing properties of the residual ink carried by the carrier liquid are preserved.Type: GrantFiled: June 6, 2003Date of Patent: December 30, 2008Assignee: ConteInventors: Vincent Rene Michel Bedhome, Didier Lange

Patent number: 7396179Abstract: A writing instrument that includes a body provided with an ink reservoir; an inker element mounted at one end of the body; and a feeder device. The feeder device includes a duct that connects the reservoir to the inker element and opens out into the reservoir via an opening. The feeder device also includes a valve that includes a tab received in the duct, the tab being extended by a head.Type: GrantFiled: January 28, 2005Date of Patent: July 8, 2008Assignee: Société BICInventors: Didier Lange, Franck Rolion, Vincent Bedhome

Patent number: 7048459Abstract: The liquid ink writing instrument has a body containing, from its rear end towards its front end, a reservoir for the ink and a front chamber containing a capillary element for transferring ink coming from the reservoir to a writing head. The front chamber communicates with ambient air. The writing head is fed with ink by the capillary element, and projects from the front portion of the body. The reservoir is separated from the front chamber by a flexible wall having shape memory and provided with slots. The flexible wall acts as a valve suitable for opening when the ratio of the pressure inside the reservoir over the pressure inside the volume of the front chamber facing the valve exceeds a first value, and of reclosing instantly as soon as the ratio becomes less than or equal to a second value, the valve releasing the ink in the form of a jet directed towards the rear face of the capillary element. The first value of the ratio of the pressures is preferably about 1.Type: GrantFiled: July 25, 2003Date of Patent: May 23, 2006Assignee: ConteInventors: Vincent Bedhome, José Duez, Didier Lange
