Abstract

A fluid supply component for a replaceable fluid supply may include a channel fluidically coupled to a pliable fluid supply bag; a ball housed within the channel; and a gasket to prevent movement of the ball into the fluid supply bag; wherein the valve prevents fluid from entering the fluid supply bag while the fluid supply bag imparts a negative fluidic pressure.

First claim

What is claimed is:

1. A fluid supply component for a replaceable fluid supply, comprising:
a channel fluidically coupled to a pliable fluid supply bag;
a fluid supply valve comprising:
a ball housed within the channel; and
a gasket adjacent an interface between the channel and the pliant fluid supply bag to prevent movement of the ball into the fluid supply bag;

wherein the fluid supply valve prevents fluid from entering the fluid supply bag while the fluid supply bag imparts a negative fluidic pressure.

2. The fluid supply component of claim 1 , wherein the fluid supply valve is fluidically coupled to the pliable fluid supply bag.

3. The fluid supply according to claim 1 , further comprising a discharge channel fluidically coupled to the channel, the discharge channel to selectively allow an amount of fluid to exit the fluid supply component.

4. The fluid supply component of claim 3 , wherein the discharge channel selectively allows the amount of fluid to exit the fluid supply component via a discharge valve comprising a septum having a resealable hole formed therein and a ball to selectively block the hole.

5. The fluid supply component of claim 4 , wherein the discharge valve comprises a spring to force the ball against the resealable hole.

6. The fluid supply component of claim 4 , wherein the discharge channel is at an angle relative to the channel and the channel is offset from the discharge channel.

7. The fluid supply component according to claim 1 , wherein the channel further comprises a collar to secure the channel to the pliable fluid supply bag.

8. The fluid supply component according to claim 1 , wherein the channel is held within a spout of the pliable fluid supply bag.

9. A replaceable printing fluid supply to be replaced with respect to a host print system, comprising:
a container to hold a volume of printing fluid;
an outflow channel to direct an amount of fluid from the container to the host print system, wherein the outflow channel comprises an orthogonal bend;
a first fluidic valve formed within the outflow channel to prevent outflow of fluid out of the container in an uninstalled state; and
a second fluidic valve formed within the outflow channel upstream of the first fluidic valve to prevent backflow into the container.

10. The replaceable printing fluid supply of claim 9 , wherein a cap of the container comprises the outflow channel along with other printer interface components to connect the replaceable printing fluid supply to the host print system.

11. The replaceable printing fluid supply of claim 9 , wherein the outflow channel comprises a first fluidic channel and a second fluidic channel and wherein the first and second fluidic channels are arranged at angles with respect to each other and are off set with respect to each other.

12. The replaceable printing fluid supply of claim 11 , wherein the first fluidic channel comprises a septum comprising a resealable hole, a ball, and a spring, the spring to force the ball towards the resealable hole.

13. The replaceable printing fluid supply according to claim 9 , wherein the second fluidic valve comprises a ball.

14. The replaceable printing fluid supply of claim 13 , comprising a gasket to prevent movement of the ball into the container.

15. The replaceable printing fluid supply of claim 13 , comprising, a spring to force the ball towards the gasket to counteract a negative pressure from the container.

16. The replaceable printing fluid supply according to claim 9 , wherein the container is a pliable bag.

17. The replaceable printing fluid supply of claim 16 , further comprising a box and wherein the pliable bag is housed within the box.

18. The replaceable printing fluid supply according to claim 9 , wherein the container comprises a spout into which the outflow channel is housed creating a fluid barrier between the volume of printing fluid and atmosphere.

19. A bag-in-box printing fluid supply, comprising:
a pliable fluid containment bag to hold a supply of printing fluid;
a fluid output comprising a first fluidic channel and a second fluidic channel, wherein the second fluidic channel is perpendicular to the first fluidic channel; and
a fluid output interface comprising a fluid path between the bag and a fluid output, wherein the fluid output interface comprises a first fluidic valve formed upstream of a fluid output of the fluid output interface the first fluidic valve to prevent backflow into the pliable fluid containment bag, wherein the fluid output of the fluid output interface is to receive a fluid input needle of a host device.

20. The bag-in-box printing fluid supply according to claim 19 , wherein the second fluidic channel comprises a second fluidic valve to prevent outflow of fluid in pre-opened uninstalled state of the supply.

21. The bag-in-box printing fluid supply of claim 20 , wherein the first and second fluidic channels are offset from each other and formed at an angle relative to each other.

22. The bag-in-box printing fluid supply of claim 20 , wherein the second fluidic channel comprises a septum having a resealable hole defined therein to receive a needle associated with a printing device.

23. The bag-in-box printing fluid supply according to claim 19 , wherein the first fluidic valve comprises a ball housed within the channel and further comprising a gasket to prevent movement of the ball into the container.
