Abstract: The present invention is directed to a lubricating shaving aid on a shaving razor or a shaving cartridge to reduce frictional drag between a razor blade edge and a shaver's skin and to provide a lubricating film on the shaver's skin during wet shaving. The lubricating shaving aid comprises a water soluble component and a water insoluble component and is formed such that the water insoluble component is released as the water soluble component dissolves upon exposure to water. The invention further discloses a method for making the same from an aqueous dispersion of water, a water soluble component in solution, and a dispersion of a water insoluble component dispersed in the water and the solution of the water soluble component.

Abstract: Ink follower compositions include a non-polar liquid that is a mixture of high molecular weight polybutene and low molecular weight polybutene, the high molecular weight polybutene having a number average molecular weight greater than about 900 and the low molecular weight polybutene having a number average molecular weight of about 500, the ratio of high molecular weight polybutene to low molecular weight polybutene being at least 2:1; a thickener and a polar additive. The polar additive is water or a non-ionic surfactant, e.g., ethoxylated nonylphenol.

Abstract: The present invention relates to a gripping device for a hand held article. The gripping device has an encasement assembly for fitting on a hand grip portion of the article. The encasement assembly contains a controllable fluid, such as magnetorheological and electrorheological fluids. The gripping device also has an activating assembly for selectively applying a field to the controllable fluid to change its Theological behavior, e.g., increasing its viscosity. Thus, the controllable fluid can maintain the shape of the encasement assembly until the activating assembly withdraws the applied field therefrom. The present invention further relates to a manual implement that has the above gripping device fitted thereon and a method for using a manual implement having the above gripping device.

Abstract: The present invention is directed to a lubricating shaving aid on a shaving razor or a shaving cartridge to reduce frictional drag between a razor blade edge and a shaver's skin and to provide a lubricating film on the shaver's skin during wet shaving. The lubricating shaving aid comprises a water soluble polyacrylamide and a water insoluble polyurethane. The invention further discloses a method for making the same.

Abstract: A writing device generally including a uniformly cylindrical main body partially filled with a writing medium such as ink. A writing tip is inserted into a first end of the main body and a first sealing member is inserted into the second end thereof. The first sealing member is located in the main body near the second end. A pressurized gas such as nitrogen is disposed in the body between the ink and the first sealing member. Alternatively, a gas forming system may be provided in the main body to continually produce a gas as the ink is depleted to maintain pressure therein. A second sealing member is inserted into the second end of the main body to provide a dual seal gas pressurized system.

Abstract: A writing instrument is disclosed having a barrel defining an internal passage including an ink reservoir. A venting mechanism is positioned at least partially within the internal passage of the barrel adjacent an anterior end portion thereof. The venting mechanism includes an elongated body defining an axial bore therethrough in communication with the ink reservoir, and a plurality of spaced apart fins peripherally surrounding the elongated body and defining a plurality of annular channels between the fins. Each of the fins defines a groove thereon to interconnect the annular channels. The writing instrument further includes a point support member supporting a writing point and positioned adjacent an anterior end portion of the venting mechanism and defining an axial bore aligned with the axial bore of the venting mechanism.

Abstract: An erasable ink composition contains a water-insoluble polymeric dye obtained by copolymerizing ethylenically unsaturated monomers at least one of which possesses a dye moiety covalently bonded thereto. The ink is intended for use in any of a variety of marking instruments, in particular, a ball-point pen.

Abstract: Ink follower compositions include a non-polar liquid, a thickener and a polar additive. The polar additive is preferably selected from the group consisting of non-ionic surfactants, e.g., ethoxylated nonylphenols, and low molecular weight alcohols.

Abstract: A wiper for use in a container for liquids such as correction fluid consists of a cylindrical length of yieldable material within the neck of the container. The wiper may be formed as an insert which consists of a cylindrical body formed about a central axis and having an upper end in the form of an annular flange, with which to engage the container neck, and a lower end extending toward a reservoir within the container. From the body depend one or more cleaning elements angled toward the central axis, the ends of the elements extending beyond the lower end of the insert and defining a gap allowing for frictional passage of an applicator, and allowing removal of excess fluid from the applicator. The upper end terminates in a wiping lip upon which an applicator may be wiped to remove liquid before application. Excess liquid so removed flows through apertures provided between the cleaning elements.

Abstract: An erasable ink composition contains a dispersion of solid particles of water-insoluble polymer-encapsulated colorant obtained from the emulsion polymerization of at least one emulsion-polymerizable monomer in the presence of solid colorant particles. The ink is intended for use in any of a variety of marking instruments, in particular, a ball-point pen.

Abstract: An erasable ink composition contains a water-insoluble polymeric dye obtained from the polymerization of at least two coreactive polyfunctional monomers with at least one of the monomers possessing a dye moiety covalently bonded thereto. The ink is intended for use in any of a variety of marking instruments, in particular, a ball-point pen.

Abstract: Novel, improved ink compositions are aqueous-based, shock-resistant, shear-thinning inks for writing instruments having a shear index greater than 0.6. The inks are a substantially uniform dispersion including colorant(s), a water dispersible, polymeric shear-thinning material selected from the group consisting of welan gum, rhamsan gum and combinations thereof, and a substantially water-soluble polymeric viscosity modifier in a polar solvent system. While the ink compositions have a high viscosity at low shear rates, they undergo shear-thinning and are readily flowable in response to shear rates produced in writing to provide a writing ink having an especially desirable combination of performance characteristics.

Abstract: An erasable ink composition contains a water-insoluble polymeric dye obtained by the graft polymerization of a preformed water-insoluble polymer with a dye monomer possessing at least one ethylenically unsaturated site. The ink is intended for use in any of a variety of marking instruments, in particular, a ball-point pen.

Abstract: An erasable ink composition contains an aqueous dispersion of water-insoluble polymer-encapsulated colorant obtained from the emulsion polymerization of at least one hydrophobic emulsion-polymerizable monomer with at least a portion of the monomer containing colorant dissolved therein. The ink is intended for use in any of a variety of marking instruments, in particular, a ball-point pen.

Abstract: The subject invention is directed to a cartridge for a writing instrument. In particular, the writing instrument includes a surface against which the cartridge abuts. The cartridge includes a tubular body for containing ink which has a front end including an applicator for applying the ink, and a plug member disposed at least partially in a rear end of the tubular body of the cartridge. The plug member includes a path for permitting airflow into the tubular body, and a flange for cushioning the cartridge against the abutment surface of the writing instrument so as to inhibit separation of the ink from the ink applicator and absorb pressure exerted upon the ink applicator during writing.
