Abstract

A fluid cartridge system and method of removing a closure assembly from a first cartridge and a second cartridge includes a first cartridge body and a second cartridge body. A neck projects from the first cartridge body with a first outlet of the first cartridge and a second outlet of the second cartridge. A first closure having a first plug is received within the first outlet and includes a first closure coupling element. In addition, a second closure having a second plug is received within the second outlet and includes a second closure coupling element. The first closure coupling element is configured to interlock with the second closure coupling element such that securing the first cartridge body against the second cartridge body also connects the first closure to the second closure. As such, the first and second closures form the closure assembly for being collectively removed by an operator.

First claim

What is claimed is:

1. A fluid cartridge system for dispensing a first fluid and a second fluid respectively from a first cartridge and a second cartridge via a dispensing applicator, the fluid cartridge system comprising:
a first cartridge body having a first chamber for containing the first fluid;
a second cartridge body having a second chamber for containing the second fluid, wherein said first cartridge body is configured to secure against said second cartridge body in a side-by-side configuration;
a first neck portion projecting from said first cartridge body and including a first outlet communicating with said first chamber for discharging the first fluid therefrom;
a second neck portion projecting from said second cartridge body and including a second outlet communicating with said second chamber for discharging the second fluid therefrom, said first neck portion configured to operatively connect to said second neck portion to form a neck;
a first closure including a first plug projecting therefrom, said first plug received within said first outlet to fluidly seal said first outlet of said first cartridge, said first closure having a first closure coupling element; and
a second closure received within said second outlet of the second cartridge, wherein the second closure is configured to operatively connect to the first closure coupling element to form a closure assembly to be removed,
wherein said first cartridge body and said first closure are configured such that securing said first cartridge body to said second cartridge body simultaneously connects said first closure to said second closure, and removal of one of the first and second closures causes the other of the first and second closures to be simultaneously removed.

2. The fluid cartridge system of claim 1 , wherein said first closure further comprises:
a first base section abutting against said first neck portion; and
a first extension projecting from said first base section, said first extension having said first plug received within said first outlet,
wherein said first base section includes said first closure coupling element configured to interlock with a second closure coupling element of the second closure.

3. The fluid cartridge system of claim 2 , wherein said first closure coupling element is a tongue, and said tongue is configured to interlock with the second closure coupling element in the form of a groove.

4. The fluid cartridge system of claim 2 , wherein a first snap member extends distally from said first base section, and said first snap member engages said first neck portion and removably secures said first base section to said first neck portion.

5. The fluid cartridge system of claim 4 , further comprising:
a first lever projecting proximally from said first base section and connected to said first snap member, said first lever configured to pivot said first snap member and disengage said first snap member from said first neck portion.

6. The fluid cartridge system of claim 1 , further comprising:
a first fluid contained within said first cartridge body, and said first fluid being a first viscous liquid.

7. The fluid cartridge system of claim 1 , wherein:
the second closure includes a second plug projecting therefrom, said second plug received within said second outlet to fluidly seal said second outlet of said second cartridge, said second closure having a second closure coupling element connected with said first closure coupling element of said first closure.

8. The fluid cartridge system of claim 7 , further comprising:
a first fluid contained within said first cartridge body, a second fluid contained with said second cartridge body, and said first and second fluids being a first viscous liquid and a second viscous liquid, respectively.

9. The fluid cartridge system of claim 8 , further comprising:
a dispensing applicator receiving said first and second cartridges, said dispensing applicator including a nozzle connected to said neck and configured to dispense said first and second viscous liquids from said first and second cartridges.
