The present disclosure provides supports for microfluidic die that allow for nozzles of the microfluidic die to be on a different plane or face a different direction from electrical contacts on the same support. This includes a rigid support having electrical contacts on a different side of the rigid support with respect to a direction of ejection of the nozzles, and a semi-flexible support or semi-rigid support that allow the electrical contacts to be moved with respect to a direction of ejection of the nozzles. The semi-flexible and semi-rigid supports allow the die to be up to and beyond a 90 degree angle with respect to a plane of the electrical contacts. The different supports allow for a variety of positions of the microfluidic die with respect to a position of the electrical contacts.

Support substrates for microfluidic die

Microfluidic delivery systems for dispensing a fluid composition into the air comprising microfluidic die and at least one heating element that is configured to receive an electrical signal comprising a certain on-time and wave form to deliver a fluid composition into the air.

Microfluidic delivery system

A method of connecting a cartridge comprising a fluid composition with a microfluidic delivery system is provided. The method includes the steps of: providing a housing comprising electrical contacts, wherein the electrical contacts of the housing are disposed on a first plane; providing a cartridge comprising a reservoir for containing a fluid composition, a die comprising a nozzle, and electrical contacts that are in electrical communication with the die, wherein the electrical contacts of the cartridge are disposed along a second plane that is parallel with the first plane; and connecting the cartridge with the housing by moving the cartridge in a direction parallel with the second plane toward the housing until the electrical contacts of the cartridge are in electrical communication with the electrical contacts of the housing.

Microfluidic delivery cartridges and methods of connecting cartridges with microfluidic delivery systems

Microfluidic delivery systems and methods for dispensing a fluid composition into the air comprising microfluidic die and at least one heating element that is configured to receive an electrical signal comprising a certain on-time and wave form to deliver a fluid composition into the air.

Method of delivering a dose of a fluid composition from a microfluidic delivery cartridge

A microfluidic fluid delivery device and method. The device includes a reservoir and a transport member. The device includes a microfluidic delivery member including a microfluidic die configured to release a fluid composition from the device. The microfluidic delivery member includes an adapter configured to receive an end portion of the transport member, wherein a capillary passage is formed between the adapter and the transport member. The capillary passage has a largest effective pore size that is smaller than the average effective pore size of the transport member.

Microfluidic delivery system for releasing fluid compositions

A microfluidic refill includes a reservoir having a hollow body and an opening; a transport member in fluid communication with the reservoir; and a lid enclosing the opening of the reservoir. The lid is in fluid communication with the transport member. The lid comprises a rigid microfluidic delivery member. The rigid microfluidic delivery member includes a die and electrical traces that are in electrical communication with the die, wherein the electrical traces terminate at electrical contacts, wherein the electrical traces are disposed on only one plane. The die has a fluid chamber in fluid communication with the transport member at an inlet of the fluid chamber and with an orifice at an outlet of the fluid chamber and.

Techniques for liquid replenishment in a printer/plotter. An ink delivery system (IDS) is employed wherein the on-carriage spring reservoir of the print cartridge is manually and securely connected to the off-carriage reservoir. A pen cartridge that uses an internal spring to provide vacuum pressure is connected from an inlet port through a unitary coupler to an ink reservoir located off the scanning carriage axis. The coupler serves to align as well as to secure two mating valves to securely hold them together in an open latched position which is not intended to be modified or disconnected until the entire ink supply has been depleted. A replaceable ink supply module for providing replenishment of an inkjet printhead includes a collapsible bag, an enclosure box, a connective tube, and an on/off valve. These four components are incorporated into a composite sealed system which remains intact during shipment, storage, installation and operation. The collapsible bag is placed inside the protective enclosure box and has an end-connect outlet permanently attached to one end of the connective tube. The other end of the connective tube carries a permanently attached on/off valve designed for engagement with an inlet valve of an inkjet printhead.
