  • Ball-point writing instrument containing an aqueous ink composition
    Patent number: 5013361
    Abstract: Aqueous based shear-thinning ink compositions and ball-point pens including the ink compositions. The ink compositions have a shear thinning index of from about 0.01 to about 0.6 and include colorant material(s) and a water dispersible, polymeric shear-thinning material substantially uniformly dispersed in a highly polar solvent system in which water is the primary solvent for the shear-thinning material.
    Type: Grant
    Filed: November 23, 1987
    Date of Patent: May 7, 1991
    Assignee: The Gillette Company
    Inventors: Laura K. Case, deceased, Chandrasen Gajria, Rachel M. Loftin, Henry Peper
  • Ball-point writing instrument containing an aqueous ink composition
    Patent number: 4671691
    Abstract: Gelled, aqueous inks are used in conjunction with viscoelastic ink follower compositions to avoid the necessity of using a fibrous ink reservoir or a porous or extruded ink feed rod.
    Type: Grant

    Date of Patent: June 9, 1987
    Assignee: The Gillette Company
    Inventors: Laura K. Case, Chandrasen Gajria, Rachel M. Loftin, Henry Peper
  • Pressurized cartridge for a writing instrument
    Patent number: 4498797
    Abstract: A writing instrument cartridge contains a loose fitting ball follower disposed within the cartridge between an end of a column of paste like ink exhibiting a yield value, and compressed gas contained in a sealed end of the cartridge. The ball follower is adapted to help peel the ink from the tube walls without contact and to prevent the gas from channeling through the ink and escaping from the cartridge past a ball point or nib during writing.

    Assignee: The Gillette Company
    Inventors: Henry Peper, Thomas E. Eaton, Edward J. Ferguson
  • Ball-point instruments writing with improved transitorially erasable trace and ink compositions therefor
    Patent number: 4097290
    Abstract: The invention relates to a ball-point writing instrument capable of writing with an intense colored or black line which is easily visible and readable and as permanent and eventually non-erasable as the best customary ball-pen ink traces, but which, in addition, is easily erasable by mechanical means for an initial period of about two to four hours as a normal graphite pencil trace, without the use of bleaches or chemicals. These properties are attained by the provision of a novel ink composition containing stated rubbers and volatile solvents which control erasability.
    Type: Grant

  • Method of cutting and grinding porous pen tips
    Patent number: 3998982
    Abstract: A method of increasing the resistance of delicate, elongated objects made of polymeric compositions, to fracturing, shattering, and splintering during application of stress forces during cutting, shearing or grinding, thereby permitting the formation of shorter finished objects with appropriately and smoothly contured ends from a long stock object. Differently stated, the present invention relates to a method of preparing an elongated, rod-like object composed of several plastic, polymeric compositions, having channels formed therein and extending longitudinally thereof, for subsequent cutting of such long object into short lengths with desirably shaped end surfaces.
