Abstract
A writing instrument such as a pen or stylus, that is capable of writing contemporaneously in different physical characteristics, such as color and visual appearance—that is, without the need to switch out different cartridges to write in different characteristics; as well as to an ink device for such a writing instrument, such as a multi-cartridge tip having multiple nibs, where the multiple nibs can be used to write on a substrate contemporaneously. A writing instrument herein can be configured to write at a substantially perpendicular angle to the substrate, or slightly angled for ease of a user's hand position. A writing instrument that encompasses both electronic and manual (ink) features is also contemplated.
Claims13
An ink device for a writing instrument having a barrel, the ink device being configured to be enclosed within the barrel, the ink device comprising:
- (a) two or more ink cartridges, each of the ink cartridges containing ink;
- each of the ink cartridges having a proximal end and an opposite distal end;
- and
- (b) two or more nibs, each nib connected to the proximal end of said two or more ink cartridges,
- wherein a proximal end of one or more nibs is angled such that, when placed within the barrel of the writing instrument, a plane formed by the proximal ends of the nibs is substantially parallel to the surface of a substrate when the writing instrument is held at an angle of 30 to 150 degrees relative to the surface of the substrate, and
- wherein the ink device is configured such that, when placed within the barrel of the writing instrument, the plurality of nibs are disposed radially around a center nib and extend through a proximal end of the barrel and transfer the ink from the cartridges to a substrate contemporaneously, providing a discernible effect of two or more characteristics.
A writing instrument comprising:
- (a) a tip, the tip having a proximal end and an opposite distal end, the tip tapering from a first diameter at the distal end to a second, narrower diameter at the proximal end, wherein the proximal end of the tip is angled such that a plane formed by the proximal end of the tip is substantially parallel to the surface of a substrate when the writing instrument is held at an angle of 30 to 150 degrees relative to the surface of the substrate;
- (b) two or more ink cartridges disposed within the tip, each of the ink cartridges comprising a proximal end connected to or integrated with a nib configured to transfer ink from within the two or more ink cartridges to a substrate, and each of the ink cartridges having a different physical characteristic from the at least one other ink cartridge;
- wherein the writing instrument is configured such that, when the two or more nibs are contacted with a substrate, the plurality of nibs extend through a proximal end of the tip and transfer the ink from the cartridges to a substrate contemporaneously, providing a discernible effect of two or more physical characteristics.
A writing instrument comprising:
- (a) a substantially triangular tip;
- and
- (b) two or more ink cartridges disposed within the tip, each of the ink cartridges comprising a proximal end and a distal portion, the proximal end connected to or integrated with a nib and configured to contemporaneously transfer ink from the two or more ink cartridges to a substrate;
- each of the ink cartridges having a different physical characteristic from the other ink cartridge;
- wherein the tip comprises a hole corresponding to each of the nibs, through which each individual nib extends to contact the substrate.
