Problems solved by technology

Further, even if the adhesive layer 40 is joined, since the process of hardening the side sealant 16 needs to be carried out at a temperature of about 100° C. for at least one hour, the heat generated by this process may cause the strength of the adhesive layer 40 to decrease or cause the bonding part to detach

Embodiment Construction

[0032]The following detailed references pertain to the present invention, examples of which will be described with reference to the accompanying drawings, in which like numerals refer to like elements. The embodiments are described below in order to explain the present invention by referring to the figures.

[0033] Hereinafter, embodiments of an ink cartridge and a method of manufacturing the same according to the present invention will be described with reference to the accompanying drawings.

[0034] see Figure 5 with 6 , a head chip 33 with multiple nozzles (similar to Figures 1 to 3 13) in the box body 38 (similar to figure 1 with 2 18) in the head chip mounting part (similar to figure 1 12 of them). In order to prevent ink from leaking between the head chip 33 and the cartridge body 38, the side sealant 36 (similar to figure 2 16) in is filled in the space between the head chip 33 and the head chip mounting portion. On the remaining portion of the upper surfac...

Abstract

An ink cartridge with an adhesive insulation layer and method of fabricating the same are provided. The ink cartridge includes a cartridge main body, a head chip mounted on an upper surface of the cartridge main body, and a flexible printed circuit electrically connected to the head chip and attached to the upper surface of the cartridge main body, wherein the cartridge main body and the flexible printed circuit are adhered to each other by an insulation layer disposed between the cartridge main body and the flexible printed circuit. In addition, the method of fabricating the ink cartridge includes applying sealant on a head chip mounting portion located at the upper surface of a cartridge main body, applying insulation material on a rear surface of an assembly of the head chip and the flexible printed circuit on which a conductive trace is formed, attaching the head chip to the head chip mounting portion, and hot-pressing the flexible printed circuit to attach the flexible printed circuit to the upper surface of the cartridge main body.

Description

technical field [0001] The present invention relates to an ink cartridge having an adhesive insulating layer and a method of making the same, and more particularly, the present invention relates to a structure for adhering a flexible printed circuit to the body of the ink cartridge and making the flexible printed circuit Insulated from the cartridge body. [0002] This application claims priority from Korean Patent Application No. 2004-55766 filed on July 16, 2004. This Korean patent application is hereby incorporated by reference in its entirety. Background technique [0003] Various types of imaging devices have been used recently. In particular, inkjet printers have been widely used due to their low cost and ease of color realization. The inkjet printer ejects the ink stored in the ink cartridge in the form of minute ink droplets through an ejection portion, thereby printing a desired image on the surface of the recording medium. Inkjet printers can be classified into...
