Abstract

Various embodiments of the present disclosure provide a cartridge for dispensing two-part fluids. In one embodiment, the cartridge comprises a cartridge body having a dispensing end and defining a first fluid reservoir and a second fluid reservoir. The dispensing end defines at least one aperture fluidly connected to the first fluid reservoir. The dispensing end also defines a dispensing conduit fluidly connected to the second fluid reservoir. The cartridge further comprises a nozzle member engageable with the cartridge body to form an outlet and to fluidly connect the at least one aperture to the outlet.

First claim

The invention claimed is:

1. A cartridge for dispensing two-part fluids, the cartridge comprising:
a cartridge body having a dispensing end and defining:
a first fluid reservoir defining a first inner surface;
a second fluid reservoir positioned at least partially within the first fluid reservoir and spaced apart from the first inner surface at a first radial distance, the dispensing end defining a plurality of apertures spaced apart from each other, each of the plurality of apertures being fluidly connected to the first fluid reservoir and having a width of a second radial distance, the second radial distance being less than the first radial distance;
a shoulder integrally connecting a dispensing conduit to the second fluid reservoir at the dispensing end;
wherein the plurality of apertures are disposed on the shoulder; and
a nozzle member engageable with the cartridge body to form an outlet and to fluidly connect the plurality of apertures to the outlet, wherein a first portion of the cartridge body is connectable with the nozzle member and spaced apart from the first inner surface at a third radial distance, the third radial distance being greater than the second radial distance and less than the first radial distance± wherein the shoulder extends in a plane that is coplanar with the first portion of the cartridge body and the plurality of apertures.

2. The cartridge of claim 1 , wherein the dispensing conduit comprises a dispensing conduit outlet.

3. The cartridge of claim 2 , further comprising a cap attachable to the nozzle member to close the outlet and the dispensing conduit outlet.

4. The cartridge of claim 3 , wherein the cap defines a second inner surface and comprises:
an annular portion protruding from the second inner surface and configured to seal the outlet; and
a circular portion separated from the annular portion, the circular portion protruding from the second inner surface and configured to seal the dispensing conduit outlet, the annular and circular portions being concentric.

5. The cartridge of claim 1 , wherein the second fluid reservoir is positioned generally within the first fluid reservoir.

6. The cartridge of claim 5 , wherein the first and second fluid reservoirs are concentric.

7. The cartridge of claim 1 , wherein the nozzle member is engageable with the dispensing end to form an outer conduit around the dispensing conduit.

8. The cartridge of claim 1 , wherein the nozzle member is threadably engageable with the cartridge body.

9. The cartridge of claim 1 , wherein the nozzle member comprises an outer surface and multiple lobes formed on the outer surface.

10. The cartridge of claim 1 , wherein the outlet and a dispensing conduit outlet of the dispensing conduit are concentric.

11. The cartridge of claim 10 , wherein the outlet and the dispensing conduit outlet are in close proximity.

12. A cartridge for dispensing two-part fluids, the cartridge comprising:
a cartridge body including a dispensing end defining:
a plurality of apertures spaced apart from each other;
a dispensing conduit;
a first fluid reservoir from which first fluid can flow to each of the plurality of apertures for dispensing, the first fluid reservoir defining a first inner surface;
a second fluid reservoir from which second fluid can flow to the dispensing conduit for dispensing, the second fluid reservoir positioned at least partially within the first fluid reservoir and spaced apart from the first inner surface at a first radial distance, each of the plurality of apertures having a width of a second radial distance; and
a shoulder integrally connecting the dispensing conduit to the second fluid reservoir at the dispensing end;
wherein the plurality of apertures are disposed on the shoulder; and
a nozzle member engageable with the dispensing end of the cartridge body to form an outlet and to form a fluid path from each of the plurality of apertures to the outlet, wherein the outlet is disposed in close proximity to a dispensing conduit outlet of the dispensing conduit, wherein a first portion of the cartridge body is connectable with the nozzle member and spaced apart from the first inner surface at a third radial distance, the third radial distance being greater than the second radial distance and less than the first radial distance, wherein the shoulder extends in a plane that is coplanar with the first portion of the cartridge body and the plurality of apertures.

13. The cartridge of claim 12 , further comprising a cap attachable to the nozzle member to close the outlet and the dispensing conduit outlet.

14. The cartridge of claim 13 , wherein the cap defines a second inner surface and comprises:
an annular portion protruding from the second inner surface and configured to seal the outlet; and
a circular portion separated from the annular portion, the circuit portion protruding from the second inner surface and configured to seal the dispensing conduit outlet, the annular and circular portions being concentric.

15. The cartridge of claim 14 , wherein the first and second fluid reservoirs are concentric.

16. The cartridge of claim 11 , wherein the outlet and the dispensing conduit outlet are concentric.
