A fluid barrier may include a collar coupled to a first end of a fluidic channel of a fluidic interface wherein the collar comprises a lip to prevent separation of the fluidic channel from a pliable fluidic container. A printing fluid supply may include an at least partially collapsible fluid bag; and a substantially rigid fluidic interface having a fluidic channel fluidically coupled to the fluid bag and a collar coupled to the fluidic channel forming a fluid barrier between the fluid bag and the fluidic interface.

Collar for fluid barrier

A container assembly may include a regulated tank to contain a fluid, a free tank to replenish the fluid in the regulated tank, a first expandable member between an interior of the regulated tank and ambient atmospheric pressure, a second expandable member between the interior of the regulated tank and an inflation port, a first valve to selectively connect the free tank to the regulated tank based upon a pressure differential between the interior of the regulated tank and an interior of the free tank and a second valve actuatable between an open state permitting an interior of the free tank to be pressurized and a closed state. The second valve is actuatable between the open state and the closed state based upon a position of the first expandable member.

Container assembly

In some examples, a container assembly includes a first body to supply a printing composition, the first body comprising a first port, and the container assembly includes a second body to store a reserve printing composition, the second body comprising a second port. An interconnect has a storage position to fluidically isolate the first body from the second body, and a use position to fluidically connect the first body to the second body to allow the reserve printing composition to flow from the second body to the first body to replenish the printing composition in the first body and to allow air in the first body displaced by the reserve printing composition to flow from the first body to the second body. The interconnect in the storage position has a first orientation to fluidically isolate the first port from the second port, and the interconnect in the use position has a second orientation rotated with respect to the first orientation to fluidically connect the first port to the second port.

Examples of a container assembly are disclosed herein. An example of the container assembly includes a first body to supply printing composition and a second body to store reserve printing composition. The example of the container assembly additionally includes an interconnect having a storage position to fluidically isolate the first body from the second body and a use position to fluidically connect the first body to the second body to allow the reserve printing composition to flow from the second body to the first body as needed to replenish the printing composition in the first body and to allow air in the first body displaced by the reserve printing composition to flow from the first body to the second body.

Examples of a container assembly are disclosed herein. An example of the container assembly includes a regulated tank to supply printing composition and a free tank to supply reserve printing composition to the regulated tank. The container assembly also includes a regulator assembly to control flow of the reserve printing composition from the free tank to the regulated tank and an inflation assembly to prime the regulated tank to supply the printing composition. The container assembly additionally includes a labyrinth to fluidically isolate the flow of ambient air into and out of the regulator assembly from the flow of a supply of air into the inflation assembly.

An integrated multifunctional valve device includes a surface member having a first port and a second port formed therein, a flexible disk member having a central portion and a surrounding portion, a first seat member extending outward from the surface member and coupled to the surrounding portion of the flexible disk member, a second seat member extending outward from the surface member and surrounded by the first seat member. The central portion is movable between an open port position to establish fluid communication between the respective ports and a close port position to stop the fluid communication between the respective ports. The second seat member is configured to selectively receive the central portion of the flexible disk member corresponding to the close port position. The integrated multifunctional valve device also includes an actuator member configured to selectively move the central portion of the flexible disk member into the open port position and the close port position.

Integrated multifunctional valve device

A flexible circuit is staked to an ink-jet pen body to resist peeling from the body and to provide a flat surface to which mechanisms for enclosing the pen nozzles can be sealed. Also disclosed is a staking apparatus and method for ensuring flatness and uniform bonding of the staked circuit.
