Problems solved by technology

This can lead to limitations in printer design and access to inkjet cartridges, as well as increased complexity in replacing inkjet cartridges
Additionally, some flex circuit structures are relatively complex to manufacture and attach to complex shaped cartridges
[0004] Additionally, flex circuit structures may be made of expensive materials such as polyimide
Also, the flexibility of the circuit board can make the electrical connection between the inkjet cartridge and the printer poor

Abstract

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.

Description

technical field [0001] The present disclosure generally relates to systems for delivering fluid compositions into the air, and more particularly, to, for example, microfluidic delivery systems, including systems for delivering fluid compositions, such as fragrance compositions, by thermally activating them. Microfluidic delivery refill for delivery into air. Background technique [0002] Various systems exist to deliver volatile compositions such as fragrance compositions into the air by powered (ie electric / battery powered) microfluidic atomization. Attempts have been made to deliver fragrances using thermally activated microfluidic delivery systems, and specifically thermal inkjet systems. However, some of these attempts have involved printing ink-based scented fluids onto substrate or surface media using methods similar to those used to print ink onto substrates or surfaces. [0003] Thermal inkjet technology utilizes a replaceable cartridge that contains a fluid and a ...
