A microfluidic delivery device and method of dispensing a fluid composition therefrom is provided. The microfluidic delivery device includes a housing electrically connectable with a power source; a cartridge releasably connectable with the housing; and a fan connected with the housing. The cartridge has a reservoir for containing a fluid composition and microfluidic die in fluid communication with the reservoir. The die is configured such that substantially all of the fluid composition exits the microfluidic die in a horizontal direction or downward direction relative to horizontal. The fan is configured to generate air flow that converges with and redirects the fluid composition dispensed from the microfluidic die in an upward direction relative to horizontal.

Microfluidic delivery device and method for dispensing a fluid composition upward into the air

A fluid interconnect system including a mating component having an inlet port and a liquid outlet, the inlet port configured to support an interconnector and the liquid outlet configured to engage with a print cartridge so that liquid flows from a liquid source, through the interconnector and the inlet port, and out of the liquid outlet into the print cartridge.

Fluid interconnection for bulk ink supply

A fluidic dispensing device includes a housing having an exterior wall and a chamber. The exterior wall has a first opening. The chamber has an interior space and has a port coupled in fluid communication with the first opening. A stir bar is located in the chamber. The stir bar has a rotational axis. A guide portion is located in the chamber. The guide portion includes a confining member having a guide opening that defines an interior radial confining surface that engages the stir bar, wherein the guide opening facilitates a radial movement of the stir bar in a direction substantially perpendicular to the rotational axis.

Fluidic dispensing device having a moveable stir bar

A film sealed ejection cartridge assembly is disclosed. The cartridge assembly includes a cartridge for fluidic ejection, as well as a cartridge retainer having a plurality of retainer walls and a retainer opening. The cartridge retainer receives and secures the cartridge. The cartridge assembly further includes a length of a nozzle plate seal film. A first portion of the nozzle plate seal film is removably secured to the fluidic ejection chip and a second portion of the nozzle plate seal film is secured to the cartridge retainer. Removal of the cartridge from the cartridge retainer causes the nozzle plate seal film to separate from the fluidic ejection chip.

A method for maintaining a fluidic dispensing device includes providing a fluidic dispensing device having a fluid reservoir containing fluid, the fluid reservoir being defined in part by a base wall, and having a stir bar located in the fluid reservoir adjacent to the base wall, and having a fluid ejection chip having a fluid ejection direction; positioning the fluidic dispensing device at a predetermined orientation, wherein the fluid ejection direction is oriented in a range of upward vertical, plus or minus 90 degrees; and rotating the stir bar in a first rotational direction starting with a first rotational speed and increasing rotational velocity from the first rotational speed to a second rotational speed.

Method of maintaining a fluidic dispensing device

A fluidic dispensing device includes a housing having a chamber that defines an interior space, and has an inlet port and an outlet port. A flow control portion has a flow separator feature. The flow separator feature is positioned adjacent the inlet port. A stir bar is located in the chamber, has a rotational axis, and has a plurality of paddles, with each paddle having a free end tip. The stir bar has a stir bar radius from the rotational axis to the free end tip. A guide portion confines the stir bar in a predetermined portion of the interior space of the chamber. A ratio of the stir bar radius and a clearance distance between the free end tip and the flow control portion is 5:2 to 5:0.025.

Fluidic dispensing device having a guide portion

A fluidic dispensing device for dispensing a fluid has a body having a chamber with a perimetrical end surface. An ejection chip is attached to the body in fluid communication with the chamber. A diaphragm has a dome portion and a perimeter sealing surface. The perimeter sealing surface of the diaphragm is in sealing engagement with the perimetrical end surface of the chamber to define a fluid reservoir that contains the fluid. The diaphragm has a deflection axis that is substantially perpendicular to a plane of the perimeter sealing surface. The diaphragm has a cross-section profile that controls a deflection of the dome portion to collapse along the deflection axis in a direction that is at least one of toward or away from a plane of the perimeter sealing surface as the fluid is depleted from the fluid reservoir.

Fluidic dispensing device

A fluidic dispensing device includes a housing having an exterior wall and a fluid reservoir. The exterior wall has a chip mounting surface defining a first plane and has a first opening. The fluid reservoir is in fluid communication with the first opening. An ejection chip is mounted to the chip mounting surface. The ejection chip is in fluid communication with the first opening. The ejection chip has a plurality of ejection nozzles oriented such that a fluid ejection direction is substantially orthogonal to the first plane. A stir bar is moveably confined within the fluid reservoir. The stir bar has a plurality of paddles and a rotational axis, with each of the plurality of paddles having a free end tip that intermittently faces toward the first opening that is in fluid communication with the ejection chip as the stir bar is rotated about the rotational axis.

A fluidic dispensing device for dispensing a fluid has a body having a chamber with a perimetrical end surface. The body has a stepped arrangement that includes a channel having a first inner side wall that defines a recessed path around the perimetrical end surface. A diaphragm has a dome portion, a perimetrical positioning rim, and a sealing surface. The channel of the body is sized and shaped to receive the perimetrical positioning rim of the diaphragm. The first inner side wall of the channel of the body engages a perimeter of the perimetrical positioning rim of the diaphragm to position the sealing surface of the diaphragm for sealing engagement with the perimetrical end surface of the chamber to define a fluid reservoir.

A packaged fluidic ejection cartridge assembly is disclosed. The cartridge assembly includes a cartridge for fluidic ejection, a cartridge storage container, and a cartridge retainer rotatably attached to the container so as to rotate about a pivot axis. The cartridge retainer receives and secures the cartridge within the storage cup. A moisture barrier film is sealed over the storage cup. The storage container may be stored with the pivot axis in either a substantially horizontal position or a substantially vertical position. The center of mass of the cartridge retainer and the cartridge within the retainer are offset from the pivot axis so that the center of mass rotates to a position below the pivot axis when the packaged cartridge assembly is stored with the pivot axis in a substantially horizontal position.

Packaging system for fluidic ejection cartridge with cartridge orientation control

A fluidic dispensing device includes a casing having a reservoir chamber and a primary vent chamber. An end cap is positioned at an end of the casing. The end cap is connected to the casing. A vent path extends from the primary vent chamber to the atmosphere through a gap between the end cap and the casing.
