Abstract
Methods and devices for dispensing fluids are provided, including a method of dispensing a fluid into an elongated chamber having a bottom that is at least partially closed. The method includes (a) inserting a dispensing tube into the chamber until a delivery end of the tube is adjacent the bottom of the chamber; (b) dispensing a predetermined quantity of the fluid through the delivery end into the chamber; and (c) moving the delivery end away from the bottom of the chamber, during dispensing, at a rate that maintains the delivery end on the surface of the fluid in the chamber throughout dispensing.
Claims21
A method of dispensing a fluid into an elongated chamber having a bottom that is at least partially open, comprising:
- (a) inserting a dispensing tube into the chamber until a delivery end of the tube is adjacent the bottom of the chamber;
- (b) dispensing a predetermined quantity of the fluid through the delivery end into the chamber;
- and
- (c) causing the delivery end to move away from the bottom of the chamber, during dispensing, at a rate that maintains the delivery end within 0.5 mm or less of the surface of the fluid in the chamber throughout dispensing.
A method of dispensing a fluid into the reservoir of a writing instrument having a first end and a writing tip adjacent and in fluid communication with the first end, during manufacture of the writing instrument, comprising the sequential steps of:
- (a) inserting a dispensing tube into the reservoir until a delivery end of the dispensing tube is adjacent the first end of the reservoir;
- (b) dispensing a predetermined quantity of the fluid through the delivery end of the dispensing tube into the reservoir;
- and
- (c) degassing the fluid prior to the dispensing step.
A method of dispensing a fluid into an elongated chamber having a bottom that is at least partially closed, comprising:
- (a) inserting a dispensing tube into the chamber until a delivery end of the tube is adjacent the bottom of the chamber;
- (b) dispensing a predetermined quantity of the fluid through the delivery end into the chamber;
- and
- (c) causing the delivery end to move away from the bottom of the chamber, during dispensing, at a rate that maintains the delivery end at or slightly above the surface of the fluid in the chamber throughout dispensing;
- and
- (d) degassing the fluid prior to the dispensing step.
A method of dispensing a fluid into the reservoir of a writing instrument having a first end including a ball point and a writing tip adjacent and in fluid communication with the first end, during manufacture of the writing instrument, comprising the sequential steps of:
- (a) inserting a dispensing tube into the reservoir until a delivery end of the dispensing tube is adjacent the first end of the reservoir and contacts the ball of the ball point;
- and
- (b) dispensing a predetermined quantity of the fluid through the delivery end of the dispensing tube into the reservoir.
