Abstract

A bag-in-box fluid supply may include a bag comprising a spout extending therefrom, the spout including a flange coupled to a surface of the bag and comprising a lip formed on the spout distal to the bag; a box formed around the bag to maintain the bag therein; a wedge to wedge a surface of the box between the lip and a surface of the bag; and a fluid interface to fluidically interface with the spout of the bag, the fluid interface including a fluidic channel and a collar disposed on a first end of the fluidic channel to secure the fluid interface to the spout.

First claim

What is claimed is:

1. A bag-in-box fluid supply, comprising:
a bag comprising a spout extending therefrom, the spout comprising a flange coupled to a surface of the bag and comprising a lip formed on the spout distal to the bag;
a box formed around the bag to maintain the bag therein;
a wedge to wedge a surface of the box between the lip and a surface of the bag; and
a fluid interface to fluidically interface with the spout of the bag, the fluid interface comprising a fluidic channel and a collar disposed on a first end of the fluidic channel to secure the fluid interface to the spout.

2. The bag-in-box fluid supply of claim 1 , wherein the surface of the spout comprises an intermediate ring formed around the spout.

3. The bag-in-box fluid supply of claim 2 , wherein the intermediate ring comprises a first ramped surface.

4. The bag-in-box fluid supply of claim 3 , wherein the first ramped surface increases in width along a direct away from a first edge of the bag.

5. The bag-in-box fluid supply according to claim 3 , wherein the wedge comprises a second ramped surface to interface with the first ramped surface and the lip.

6. The bag-in-box fluid supply according to claim 1 , wherein the fluid channel comprises a second end and wherein the second end includes a septum to selectively discharge fluid from the bag-in-box fluid supply.

7. The bag-in-box fluid supply according to claim 1 , wherein a surface of the fluidic interface abuts with a surface of the box opposite a surface abutting the wedge.

8. The bag-in-box fluid supply according to claim 1 , wherein the spout further comprises a number of ribs formed on an interior surface of the spout.

9. The bag-in-box fluid supply of claim 8 , wherein the ribs form an interference fit with a fluidic channel of the fluidic interface fluidically coupled to the bag.

10. A coupling system of a printing fluid supply, comprising:
a pinch plate comprising a wedged-shaped surface, the wedge-shaped surface to wedge a surface of a box holding a fluid supply bag between the fluid supply bag and a distal flange formed on a spout of the fluid supply bag; and
a fluidic interface comprising a collar formed on a fluid channel, the fluid channel forming an interference fit within the spout of the fluid supply bag.

11. The coupling system of claim 10 , wherein a surface of the spout comprises an intermediate ring formed around the spout.

12. The coupling system of claim 11 , wherein the intermediate ring comprises a first ramped surface.

13. The coupling system of claim 12 , wherein the first ramped surface increases in width along a direction away from a first edge of the printing fluid supply.

14. The coupling system according to claim 12 , where in the pinch plate comprises a second ramped surface to interface with the first ramped surface and the lip.

15. The coupling system according to claim 10 , wherein the fluidic interface forms a fluidic connection with a printing device.

16. The coupling system of claim 15 , wherein a surface of the fluidic interface abuts with a surface of the box opposite a surface abutting the pinch plate.

17. The coupling system according to claim 15 , wherein the spout comprises a number of ribs formed on an interior surface of the spout and wherein the ribs form an interference fit with the fluidic channel of the fluidic interface.

18. A replaceable printing fluid supply, comprising:
a fluidic interface;
a pliable bag to maintain a volume of printing fluid therein, the pliable bag comprising a spout comprising an upper flange, wherein the fluidic interface is coupled to the spout via a fluidic channel;
a container to hold the pliable bag;
a structural support comprising a wedge surface to couple the pliable bag and fluidic interface to a surface of the container by wedging the surface of the container to the upper flange.

19. The replaceable printing fluid supply of claim 18 , wherein the surface of the spout comprises a ring formed around the spout intermediate to the pliable bag and upper flange.

20. The replaceable printing fluid supply of claim 19 , wherein the intermediate ring comprises a first ramped surface.

21. The replaceable printing fluid supply of claim 20 , wherein the first ramped surface increases in width along a direction away from a first edge of the pliable bag.

22. The replaceable printing fluid supply according to claim 20 , where in the wedge surface of the structural support interfaces with the first ramped surface and the upper flange.
