Abstract

A device may include a dispensable substance container to hold a dispensable substance; a dispensing nozzle attached to the dispensable substance container to dispense the dispensable substance out of an opening in the dispensing nozzle; and a frangible obstruction encompassing the dispensing nozzle and obstructing the opening of the dispensing nozzle wherein the frangible obstruction is to slide along the dispensing nozzle to uncover the opening when broken free from the dispensing nozzle by a wall of a receiving container during an engagement between the dispensable substance container and the receiving container.

First claim

What is claimed:

1. A device, comprising:
a dispensable substance container to hold a dispensable substance;
a dispensing nozzle attached to the dispensable substance container to dispense the dispensable substance out of an opening in the dispensing nozzle; and
a frangible obstruction encompassing the dispensing nozzle and obstructing the opening of the dispensing nozzle wherein the frangible obstruction is to slide along the dispensing nozzle to uncover the opening when broken free from the dispensing nozzle by a wall of a receiving container during an engagement between the dispensable substance container and the receiving container, wherein the frangible obstruction is located within a cavity between the dispensing nozzle and a side mating wall of a mating mechanism attached to the dispensable substance container.

2. The device of claim 1 , wherein the dispensable substance is a printing substance and the receiving container is a printing substance reservoir cartridge of a printing device.

3. The device of claim 1 , wherein the dispensing nozzle includes an elongate shaft encompassing a lumen and the opening into the lumen is present through a sidewall of the elongate shaft.

4. The device of claim 3 , wherein the frangible obstruction seals the dispensable substance within the lumen of the elongate shaft until a frangible attachment between the frangible obstruction and the dispensing nozzle is broken.

5. The device of claim 4 , wherein the frangible attachment is a bond between the dispensing nozzle and the frangible obstruction.

6. A system, comprising:
a dispensable substance container to hold a dispensable substance;
a mating mechanism attached to the dispensable substance container, the mating mechanism including:
a dispensing nozzle attached to the dispensable substance container to dispense the dispensable substance out of an opening in the dispensing nozzle, and
a frangible obstruction fixed over the opening in the dispensing nozzle; and

a receiving container to receive the dispensable substance dispensed from the opening in the dispensing nozzle, the receiving container including:
an inner receiving container wall encompassing a passageway for the dispensable substance dispensed from the opening in the dispensing nozzle, the inner receiving container wall to break the frangible obstruction when the receiving container and the mating mechanism are joined.

7. The system of claim 6 , wherein the mating mechanism includes dispensing-side mating wall encompassing a cavity between the dispensing nozzle and the dispensing-side mating wall.

8. The system of claim 7 , wherein the receiving container includes an outer receiving container wall encompassing a cavity between the inner receiving container wall and the outer receiving container wall.

9. The system of claim 8 , wherein the dispensing-side mating wall seats within the cavity between the inner receiving container wall and the outer receiving container wall when the dispensable substance receiving container and the mating mechanism are joined.

10. The system of claim 9 , wherein the inner receiving container wall seats within the cavity between the dispensing nozzle and the dispensing-side mating wall when the dispensable substance receiving container and the mating mechanism are joined.

11. The system of claim 10 , wherein the frangible obstruction is translated into the cavity between the dispensing nozzle and the dispensing-side mating wall when the dispensable substance receiving container and the mating mechanism are joined to break the frangible attachment, and wherein the inner receiving container wall holds the frangible attachment away from the opening while the dispensable substance is dispensed from the opening of the dispensing nozzle.

12. The system of claim 6 , wherein to break the frangible obstruction includes to break a frangible attachment between the frangible obstruction and the dispensing nozzle.

13. A device, comprising:
a dispensing portion, including:
a dispensing nozzle,
a sleeve, attached to the dispensing nozzle, sealing an opening on a side wall of the dispensing nozzle, and
a dispensing-side mating wall encompassing the dispensing nozzle, the dispensing-side mating wall separated from the dispensing nozzle by a cavity; and

a receiving portion, including:
an inner receiving container wall defining a passageway into a dispensable substance receiving container, the inner receiving container wall to enter the cavity and introduce fluid communication between the dispensing nozzle and the dispensable substance receiving container by breaking the attachment between the sleeve and the dispensing nozzle.

14. The device of claim 13 , wherein the receiving portion includes an outer receiving container wall encompassing the inner receiving container wall, the outer receiving container wall to engage the dispensing-side mating wall and guide the dispensing nozzle into the cavity.

15. The device of claim 13 , wherein the inner receiving container wall translates a force load introduced to join the dispensing portion to the receiving portion to a shearing force to break the attachment between the sleeve and the dispensing nozzle.
