Abstract
A pen includes a housing; a first reservoir inside the housing and configured to contain a first fluid, the first reservoir including a first opening configured to dispense the first fluid; a second reservoir inside the housing and configured to contain a second fluid, the second reservoir including a second opening configured to dispense the second fluid; a first writing tip extending from the housing and configured to dispense a substantially homogeneously mixed fluid to a writing surface; and a mixing region connected to the first and second openings and the first writing tip and configured to substantially homogeneously mix the first and second fluids and dispense the substantially homogeneously mixed fluid to the first writing tip.
Claims20
A pen, comprising:
- a housing;
- a first reservoir inside said housing and configured to contain a first fluid, said first reservoir comprising a first opening configured to dispense said first fluid;
- a second reservoir inside said housing and configured to contain a second fluid, said second reservoir comprising a second opening configured to dispense said second fluid;
- a first writing tip extending from said housing and configured to dispense a substantially homogeneously mixed fluid to a writing surface;
- a mixing region connected to said first and second openings and said first writing tip and configured to substantially homogeneously mix said first and second fluids and dispense said substantially homogeneously mixed fluid to said first writing tip;
- and
- a second writing tip extendable from said housing and configured to receive only said first fluid and to dispense said first fluid unmixed with said second fluid to said writing surface.
A pen, comprising:
- a housing;
- a first reservoir inside said housing and configured to contain a first fluid, said first reservoir comprising a first opening configured to dispense said first fluid;
- a second reservoir inside said housing and configured to contain a second fluid, said second reservoir comprising a second opening configured to dispense said second fluid;
- a first writing tip extending from said housing and configured to dispense a substantially homogeneously mixed fluid to a writing surface;
- a mixing region connected to said first and second openings and said first writing tip and configured to substantially homogeneously mix said first and second fluids and dispense said substantially homogeneously mixed fluid to said first writing tip;
- and
- said first and second fluids, wherein said first fluid comprises a first chemical and said second fluid comprises a second chemical that is chemically reactive with said first chemical.
An ink pen for dispensing ink having time-dependent characteristics, comprising:
- a writing pen, comprising at least one reservoir configured to contain a fluid, and further comprising a writing tip configured to dispense said fluid to a writing surface;
- and
- a fluid ink having time-dependent characteristics contained in said at least one reservoir, said ink comprising:
- a first chemical;
- a second chemical;
- and
- a dye,
- wherein said first and second chemicals are chemically reactive and wherein their chemical reaction causes them to solidify into a solid product,
- wherein said writing pen and fluid ink are configured so that:
- at least said first and second chemicals are substantially chemically isolated from each other prior to dispensing said ink to said writing surface;
- and at least said first and second chemicals are substantially mixed with each other upon dispensing said fluid ink to said writing surface so as to chemically react with each other.
