Abstract: A shaving blade unit including a housing, at least one elongated blade having a cutting edge on the housing, an elongated guard on the housing in front of the blade, and an elongated cap on the housing behind the blade. The guard includes an elongated guard strip for delivering a shaving aid and elastomeric guard fins extending laterally beyond the ends of the guard strip. The guard can also include elastomeric material including a series of depressions. The cap can also include elastomeric cap fins on both sides of the cap strip extending laterally beyond the ends of the cap strip.

Abstract: An ink cartridge (1) for a reservoir pen has a body (2) which encloses an ink-chamber (3) that is initially sealed near the front end of the cartridge by a closure formed by a plug (4). The plug (4) sealingly engages in an axial bore (5) which is open to the front end of the cartridge and is slidably mounted in the cartridge body (2) so as to be moved rearwardly by engagement with a peg (34) upon insertion of the cartridge (1) into a pen, thereby allowing ink flow from the ink chamber (3) through the bore (5) and to a writing tip (23) of a nib (22) of the pen. The peg (34) is sized so as to form a seal with the inner surface of the bore (3) when fully inserted thereinto.

Abstract: A reservoir pen includes a nib, a feed bar defining an ink channel and having an ink port, and a valve for controlling flow of ink from the ink port to an underside of the nib. The valve includes a seat, a valve member, and a resilient element engaging the valve member to bias the valve member away from the ink port toward an open position. The valve member is further positioned to engage the nib to urge the valve member against the resilient element and into sealing contact with the seat. The resilient member is disposed outside of the ink channel in at least the open position.

Abstract: A non-erasable liquid ink for a marking instrument including a colorant and a solvent and having a water content of about 0-15% by weight and a viscosity of about 15 to 4,500 cps. Also disclosed is a marking instrument filled with an ink of such a viscosity or lower in its reservoir.

Abstract: A correction fluid bottle (1) has a neck insert (4) defining a passage through which an applicator brush can be passed, and an inner end of the insert is terminated in a steeply inclined plane to define a tapered protrusion (15) extending into the bottle for drops of fluid running back through the neck to collect at the free end of the protrusion and fall back into the bottle, thereby avoiding a build up of dried fluid at the inner end of the neck.

Abstract: A writing instrument having an elongated barrel comprised of an outer portion and an inner portion, rotatable relative one to the other. The point or writing tip is fixed to the barrel inner portion, disposed at an angle to, and may be offset from, the centerline of the barrel outer portion. The barrel inner portion is caused to rotate and move axially relative to the barrel outer portion by pressure on the writing instrument, or weights attached to the barrel inner portion, to bring the point into desired alignment during the writing process. Further pressure on the point or writing tip causes the barrel inner portion to move to a rearwardmost position at which rotation of the point or writing tip is impeded by a gripping structure.

Abstract: A marking instrument includes a reservoir chamber for marking fluid, a channel for conducting marking fluid from the reservoir chamber for supply to a marking tip, and a valve for controlling supply of fluid through the channel. The valve includes a seat member with a port, a diaphragm having an edge for cooperation with the seat member to close the port, and a free surface extending from the edge to a position at which the diaphragm is held against movement. The seat member is movable to deflect the diaphragm for opening the valve. The free diaphragm surface extends away from the edge at an angle of 45.degree. to 85.degree. when the valve is closed.

Abstract: A marking instrument, especially a reservoir pen, has a diaphragm which is deflected by retraction of a marking tip to open a port to connect a feed channel to the reservoir containing a marking fluid. A cavity communicating with the port has a volume which reduces when the diaphragm deflects to open the valve and increases when the diaphragm moves to close the valve. The diaphragm has an integral forwardly extending skirt which seals against the feed member at the forward end of the skirt. These features are effective in preventing marking liquid flowing to the tip when not required and leakage of marking fluid between the diaphragm and feed member.

Abstract: A marking instrument, such as a reservoir pen, has a valve for controlling communication between a reservoir chamber and a feed channel extending through a feed member to a marking tip. The feed member is retractable to open the valve when the tip is pressed against a surface. A subchamber is confined by a diaphragm sealingly connected between the feed member and the barrel, and when the marking tip is lifted from the surface, the diaphragm pushes the feed member forwardly so that the valve closes, after which the volume of the subchamber increases so that the ink is drawn through the channel from the tip.

Abstract: A marking instrument, e.g. a fiber tip pen, roller ball pen, or highlighter pen, has a feed device which conducts marking liquid from the reservoir chamber (17) to the marking tip supported by an elastomeric diaphragm (6) which partly confines the reservoir chamber and forms a valve with the feed device so that when tip is applied against a surface the feed device retracts causing the diaphragm (6) to pressurize the liquid in the reservoir and open the valve whereby liquid is pumped to the tip.

Abstract: A reservoir pen includes a valve operated by the pen nib (4) to allow ink to pass to the nib, the ink flow rate being controlled by a flow restricting device (8) located between a primary ink reservoir chamber (2) enclosed within the pen barrel (1) and a secondary ink reservoir chamber (6) of much smaller capacity from which an ink channel (10) leads to the valve. The device (8) is a length of an extruded rod of microporous plastics. The nib is pressed towards the feed bar (3) by one spring element (21) and the valve member (12) which cooperates with a seat defined by the feed bar is urged to its closed position by another spring element (28). The rear end of the primary ink chamber (2) is closed by a grease plug comprising a mass of grease and a skeletal reinforcing frame.
