Fluid dispensers for personal use

A method for monitoring the maintenance of a sanitized work environment comprising the steps of:

• providing a plurality of personal disposable personal dispensers to workers at said work environment, wherein said personal dispensers hold a plurality of unit doses of hand sanitizing fluid;
• monitoring, on a consistent periodic basis, the number of empty personal dispensers exchanged for new personal dispensers;
• determining, after a plurality of said monitoring steps, an average number of exchanges that correlates with a sanitized work environment;
• and
• after said step of determining an average number of exchanges that correlates with a sanitized work environment, comparing the number of empty personal dispensers exchanged in subsequent said steps of monitoring with the average number of exchanges.

A method for creating a pump mechanism having an inlet path and an outlet path communicating with a dosing chamber, wherein both the inlet and outlet paths include one-way valves, the method comprising the steps of:

• molding a first half of a body portion from rigid material, the first half of the body portion providing a first half of an inlet path, a first half of an outlet path, and a dosing chamber aperture;
• molding a second half of a body portion from rigid material, the second half of the body portion providing a second half of an inlet path, a second half of an outlet path, and a dosing chamber aperture;
• over molding a flexible material on the first half of the body portion to provide a first half of a duct bill valve in the inlet path, a first half of a duct bill valve in the outlet path, and a first half of a dosing chamber extending through the dosing chamber aperture;
• over molding a flexible material on the second half of the body portion to provide a second half of a duct bill valve in the inlet path, a second half of a duct bill valve in the outlet path, and a second half of a dosing chamber extending through the dosing chamber aperture;
• and
• joining the first and second halves of the body portion such that said first and second halves of the inlet path create a complete inlet path with a duct bill valve therein, said first and second halves of the outlet path create a complete outlet path with a duct bill valve therein, and said first and second halves of a dosing chamber create a complete dosing chamber.

A method for creating a pump mechanism having an inlet path and an outlet path communicating with a dosing chamber, wherein both the inlet and outlet paths include one-way valves, the method comprising the steps of:

• providing a mold having an inside dimension configuration that provides a domed dosing chamber shape, an inside-out duck bill valve shape extending from the domed dosing chamber shape at an open end of the duck bill valve shape and extending to a closed end of the duck bill valve shape, and an outlet conduit shape extending from the domed dosing chamber shape at an open end of the outlet conduit shape and extending to an open fill end of the outlet conduit shape;
• placing a tube of plastic material in the mold;
• blowing air through the open fill end of the outlet conduit shape of the mold to force the tube of plastic material to contact the inside dimensions of the mold, and thereby forming a pump mechanism having a dosing chamber from which a sealed inside-out duck bill valve extends and from which an outlet conduit extends;
• removing the pump mechanism from the mold;
• and
• pushing the inside-out duck bill valve inside of the dosing chamber to create an inlet conduit closed by a duck bill valve.
