Abstract

Examples described herein relate to an apparatus for particulate delivery consistent with the disclosure. For instance, the apparatus may comprise a particulate reservoir container, an orifice positioned at an output portion of the particulate reservoir container, and a baffle that when compressed forces air through an air valve to direct the air below a level of particulates of print material to aerate the particulates of print material.

First claim

What is claimed:

1. An apparatus, comprising:
a particulate reservoir container;
an orifice positioned at an output portion of the particulate reservoir container, the orifice including an air inlet to direct air at particulates of print material; and
a baffle that when compressed forces the air through an air valve to the air inlet to direct the air upwards toward an input portion of the particulate reservoir container and below the level of the particulates of the print material to aerate the particulates of the print material.

2. The apparatus of claim 1 , wherein the baffle is disposed within the particulate reservoir container.

3. The apparatus of claim 1 , wherein the baffle is disposed on an external surface of the particulate reservoir container.

4. The apparatus of claim 1 , wherein the air valve is disposed within the particulate reservoir container.

5. The apparatus of claim 1 , wherein a portion of the air valve is disposed externally of the particulate reservoir container.

6. The apparatus of claim 1 , wherein the air valve has an input end opening into the baffle.

7. The apparatus of claim 1 , wherein the air valve has a discharge end opening into the particulate reservoir container below the level of particulates of print material.

8. A system, comprising:
a particulate reservoir container;
an orifice positioned at an output portion of the particulate reservoir container, the orifice including an air inlet to direct air at particulates of print material; and
a baffle coupled to an air valve, wherein when compressed the baffle forces the air through the air valve to the air inlet to direct the air upwards toward an input portion of the particulate reservoir container and below a level of the particulates of the print material to aerate the particulates of the print material.

9. The system of claim 8 , wherein the air valve intersects with the orifice to direct the air at the particulates of print material.

10. The system of claim 8 , wherein the air valve intersects with the particulate reservoir container to direct the air at the particulates of print material.

11. The system of claim 8 , wherein a portion of the air valve is disposed at an angle to direct the air towards the level of the particulates of print material.

12. A particulate delivery container, comprising:
a particulate reservoir container;
an orifice positioned at an output portion of the particulate reservoir container, the orifice including an air inlet to direct air at particulates of print material; and
a baffle that when compressed forces the air through a one-way air valve to the air inlet to direct the air upwards toward an input portion of the particulate reservoir container and below a level of the particulates of the print material to aerate the particulates of the print material, wherein the air valve includes an input end opening at the baffle and a discharge end opening below the level of the particulates of print material.

13. The particulate delivery container of claim 12 , wherein the baffle is refilled with air upon compression via a one-way valve sealing mechanism.

14. The particulate delivery container of claim 12 , wherein the baffle is sealed.

15. The particulate delivery container of claim 12 , wherein the baffle is semi-sealed.

16. The particulate delivery container of claim 12 , wherein the baffle is disposed within the particulate reservoir container.

17. The particulate delivery container of claim 12 , wherein the baffle is disposed on an external surface of the particulate reservoir container.

18. The particulate delivery container of claim 12 , wherein the air valve is disposed within the particulate reservoir container.

19. The particulate delivery container of claim 12 , wherein a portion of the air valve is disposed externally of the particulate reservoir container.

20. The particulate delivery container of claim 12 , wherein the air valve has an input end opening into the baffle.
