Abstract

A side by side cartridge assembly for dispensing first and second fluid materials includes a first cartridge container and a second cartridge container. The cartridge containers include respective bodies and nozzle members coupled with the bodies. The cartridge containers are positionable with respect to one another such that the two nozzle members cooperate to form a cartridge outlet for dispensing first and second fluid materials from the respective bodies. The cartridge outlet includes dispensing openings communicating with respective nozzle channels, and a sealing surface configured for sealing engagement with a mixing element when a mixing element is attached to the cartridge outlet.

First claim

What is claimed is:

1. A side by side cartridge assembly for dispensing first and second fluid materials, the assembly comprising:
a first cartridge container having a first body configured to contain a supply of the first fluid material and a first nozzle member coupled with the first body and having a first nozzle channel configured to communicate with the supply of the first fluid material,
a second cartridge container having a second body configured to contain a supply of the second fluid material and a second nozzle member coupled with the second body and having a second nozzle channel configured to communicate with the supply of the second fluid material, the second cartridge container being positioned adjacent to the first cartridge container, and
a latch formed in one of the first and second nozzle members and a receiver configured to receive the latch formed in the other of the first and second nozzle members,
the first cartridge container and the second cartridge container being positionable with respect to one another such that the first nozzle member and the second nozzle member cooperate to form a cartridge outlet for dispensing the first and second fluid materials,
the cartridge outlet including a first dispensing opening communicating with the first nozzle channel and a second dispensing opening communicating with the second nozzle channel, a threaded portion configured for threadably securing a mixing element to the cartridge outlet, and an uninterrupted sealing surface surrounding the first and second dispensing openings, the sealing surface being situated between the threaded portion and the first and second dispensing openings and configured for sealing engagement with a mixing element when the mixing element is attached to the cartridge outlet, wherein the first nozzle member includes the uninterrupted sealing surface,
the latch and the receiver cooperating to secure the first cartridge container with the second cartridge container when the first nozzle member and second nozzle member are positioned to form the cartridge outlet, and
the threaded portion of the cartridge outlet being defined by a first threaded region on the first nozzle member and a second threaded region on the second nozzle member.

2. The side by side cartridge assembly of claim 1 , further comprising the mixing element secured to the cartridge outlet and including a mixing element surface in sealing engagement with the sealing surface of the cartridge outlet.

3. The side by side cartridge assembly of claim 1 , wherein the first nozzle member further includes a receiving bore and the second nozzle member further includes a stem configured to fit within the receiving bore, the second nozzle channel extending in the stem.

4. The side by side cartridge assembly of claim 3 , wherein the stem extends to the second dispensing opening when the first nozzle member and second nozzle member are positioned to form the cartridge outlet.

5. The side by side cartridge assembly of claim 1 , wherein the first cartridge container and the second cartridge container extend between respective dispensing ends and back ends, the first and second nozzle members being located proximate the dispensing ends, and further comprising a slot formed in one of the first and second bodies proximate the back end thereof and a t-shaped tab formed in the other of the first and second bodies proximate the back end thereof, the t-shaped tab fitting into the slot to secure the back end of the first cartridge container with the back end of the second cartridge container when the first nozzle member and second nozzle member are positioned to form the cartridge outlet.

6. The side by side cartridge assembly of claim 5 , the t-shaped tab including a plurality of barbs for engaging the slot and for preventing the t-shaped tab from being removed from the slot.

7. The side by side cartridge assembly of claim 5 , further comprising a retaining element for securing the dispensing ends of the first cartridge container and the second cartridge container when the first nozzle member and second nozzle member are positioned to form the cartridge outlet.

8. The side by side cartridge assembly of claim 1 , wherein the entire threaded portion of the cartridge outlet is defined on the first nozzle member.

9. The side by side cartridge assembly of claim 8 , wherein the receiver is an undercut formed in the other of the first and second nozzle members.

10. The side by side cartridge assembly of claim 1 , wherein the first nozzle member further includes a first flat surface portion and the second nozzle member further includes a second flat surface portion, the first and second flat surface portions being in confronting relationship when the first nozzle member and second nozzle member are positioned to form the cartridge outlet.

11. The side by side cartridge assembly of claim 1 , wherein the receiver is a protrusion formed in the other of the first and second nozzle members.

12. A side by side cartridge assembly for dispensing first and second fluid materials, the assembly comprising:
a first cartridge container having a first body configured to contain a supply of the first fluid material and a first nozzle member coupled with the first body and having a first nozzle channel configured to communicate with the supply of the first fluid material, the first nozzle member further including a receiving bore,
a second cartridge container having a second body configured to contain a supply of the second fluid material and a second nozzle member coupled with the second body and having a second nozzle channel configured to communicate with the supply of the second fluid material, the second nozzle member further including a stem configured to fit within the receiving bore, and
a latch formed in one of the first and second nozzle members and a receiver formed in the other of the first and second nozzle members,
the first cartridge container and the second cartridge container being positionable with respect to one another such that the first nozzle member and the second nozzle member cooperate with the stem of the second nozzle member received in the receiving bore of the first nozzle member to form a cartridge outlet for dispensing the first and second fluid materials, the second cartridge container being positioned adjacent to the first cartridge container,
the cartridge outlet including a first dispensing opening communicating with the first nozzle channel and a second dispensing opening communicating with the second nozzle channel, a threaded portion configured for threadably securing a mixing element to the cartridge outlet, and an uninterrupted sealing surface formed on the first nozzle member and surrounding the first and second dispensing openings, the sealing surface being situated between the threaded portion and the first and second dispensing openings and configured for sealing engagement with a mixing element when the mixing element is attached to the cartridge outlet, and
the latch and the receiver cooperating to secure the first cartridge container with the second cartridge container when the first nozzle member and second nozzle member are positioned to form the cartridge outlet,
wherein the threaded portion of the cartridge outlet is defined by a first threaded region on the first nozzle member and a second threaded region on the second nozzle member.

13. The side by side cartridge assembly of claim 12 , wherein the entire threaded portion of the cartridge outlet is defined on the first nozzle member.

14. A method for joining a first cartridge container and a second cartridge container to form a side
