Abstract

A fluid dispenser and method for simultaneously dispensing fluids from first and second cartridges. The fluid dispenser includes a base structure and a cartridge holding assembly mounted to the base structure. The cartridge holding assembly includes first and second cartridge holders. A linear drive mechanism is mounted to the base structure and coupled with first and second drive pistons force fluids through fluid passages. A dispensing portion is provided in first and second sections for easy cleaning.

First claim

What is claimed is:

1 . A fluid dispenser for simultaneously dispensing fluids from first and second cartridges, comprising:
a base structure; a cartridge holding assembly mounted to said base structure and including first and second cartridge holders; a linear drive mechanism mounted to said base structure; first and second drive pistons operatively connected to said linear drive mechanism and movable into respective first and second cartridges when said first and second cartridges are held in said first and second cartridge holders such that fluid is dispensed from the first and second cartridges; and a dispensing portion including respective first and second fluid passages in fluid communication with the respective first and second cartridge holders for receiving fluid from the first and second cartridges as the first and second drive pistons are moved into the first and second cartridges, said dispensing portion further comprising first and second sections removably secured together, each section having lengthwise portions of said first and second passages therein for allowing cleaning of the lengthwise portions upon removal of the first section from the second section.

2 . The fluid dispenser of claim 1 , wherein said dispensing portion further comprises an outlet passage communicating with the first and second fluid passages for receiving and dispensing the fluid from the first and second fluid passages.

3 . The fluid dispenser of claim 1 , wherein said first and second cartridge holders further comprise tubular members removably carried on said cartridge holding assembly.

4 . The fluid dispenser of claim 1 , wherein said dispensing portion is removably secured to said first and second cartridge holders.

5 . The fluid dispenser of claim 4 , wherein said dispensing portion is removably secured to said first and second cartridge holders by at least one quick connector.

6 . A method of dispensing fluids and cleaning residual fluid from a fluid dispenser adapted to simultaneously dispense the fluids from first and second cartridges, comprising:
loading first and second cartridges into respective first and second cartridge holders of the cartridge holding assembly; driving first and second pistons respectively into the first and second cartridges to force fluids from the first and second cartridges; directing the fluids from the first and second cartridges respectively into first and second fluid passages of a dispensing portion; dispensing the fluids from the first and second fluid passages; removing a first section of the dispensing portion from a second section of the dispensing portion to expose respective lengthwise portions of the first and second fluid passages in the first and second sections; and cleaning the lengthwise portions of residual fluid.

7 . The method of claim 6 , further comprising:
removing the dispensing portion from the first and second cartridge holders prior to cleaning the lengthwise portions of residual fluid.
