Abstract
A nozzle tape for an inkjet cartridge is attached to the inkjet cartridge including a head chip, a cartridge body provided with a head chip-mounting portion spaced apart from edges of the head chip by a predetermined extent, and at least one bead member protruded along the edges of the head chip, wherein the nozzle tape is provided with at least one communication portion in fluid communication with a spaced gap between the head chip and the head chip-mounting portion to make the air trapped under the nozzle tape communicate with external air through the communication portion, thereby tightly attaching the nozzle tape to the nozzles, regardless of changes of an external environment.

A nozzle tape used with an inkjet cartridge including a head chip having nozzles, a cartridge body provided with a head chip-mounting portion spaced apart from edges of the head chip by a predetermined extent to define a spaced gap around the head chip, and at least one bead member protruding along the edges of the head chip, wherein the nozzle tape is attached to the head chip of the inkjet cartridge to cover the nozzles and has at least one communication portion in fluid communication with a portion of the spaced gap at a position substantially perpendicular to the at least one bead member.
A nozzle tape used with an inkjet cartridge including a head chip having nozzles, a cartridge body provided with a head chip-mounting portion spaced apart from edges of the head chip by a predetermined extent, and at least one bead member protruding along the edges of the head chip, wherein the nozzle tape is attached to the head chip of the inkjet cartridge to cover the nozzles and has at least one communication portion in fluid communication with the spaced gap between the head chip and the head chip-mounting portion,
- wherein the communication portion is disposed in parallel with the bead member to make the bead member be inserted into the communication portion and to make both ends of the communication portion communicate with the spaced gap.
A nozzle tape used with an inkjet cartridge including a head chip, a cartridge body provided with a head chip-mounting portion spaced apart from edges of the head chip by a predetermined extent to form a spaced gap with the head chip, and at least one bead member protruding along the edges of the head chip, wherein the nozzle tape is attached to the head chip of the inkjet cartridge and has a width less than a gap between the spaced gap and at least one of the bead members to cover nozzles of the head chip and expose a portion of the spaced gap substantially perpendicular to the at least one bead member at a position adjacent to the at least one bead member.
An inkjet cartridge comprising:
- a cartridge body having a head chip-mounting portion formed on a side thereof;
- a head chip having a plurality of nozzles, and mounted in the head chip-mounting portion of the cartridge body;
- a spaced gap between the head chip and the head chip-mounting portion of the cartridge body;
- at least one bead member disposed along at least one side of the head chip to cover a portion of the spaced-gap;
- and
- a nozzle tape attached to the head chip to seal the nozzles, and having at least one communication portion to correspond to a portion of the spaced gap substantially perpendicular to the at least one bead member.
A nozzle tape used on an inkjet cartridge, the inkjet cartridge comprising:
- a head-chip having a plurality of nozzles;
- a head-chip mounting portion to mount the head-chip, defining a plurality of spaced gaps between an edge of the head-chip mounting portion and an edge of the head-chip mounted therein;
- and
- at least one encapsulating bead to cover and seal at least one of the plurality of spaced gaps,
- wherein the nozzle tape is attached to the inkjet cartridge to cover the plurality of nozzles and the nozzle tape comprises:
- at least one communication port in fluid communication with at least one spaced gap not covered by the at least one bead member and substantially perpendicular to the at least one bead member.
