DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0007] In the detailed description, numerous specific details are set forth in order to provide a thorough understanding of the invention. However, it will be understood by those skilled in the art that these are specific embodiments and that the present invention may be practiced also in different ways that embody the characterizing features of the invention as described and claimed herein.
[0008] The present invention, in some embodiments thereof, provides a unique ink cartridge for printers and a unique technique for economical printing, using this permanent single use cartridge unit that is installed in a printer optionally as an integral part thereof. The permanent single use cartridge unit is refillable with unique ink capsules, each capsule having an ink material kept sealed and in an initial solid state, which dissolves into liquid under certain conditions or through a certain chemical or electrical processes. Therefore, the cartridge is configured such that only when the capsule is inserted into the cartridge unit it liquefies (also referred to herein as "dissolves") into a disposable liquid ink. The initiation of the liquefied state can be achieved in different techniques using a dissolving mechanism based on the configuration of the cartridge.
[0009] One technique suggested and exemplified by the present invention is a mechanical dissolving mechanism using sharp projection installed within the cartridge unit. The sharp projection cut the skin layer of the unique ink capsule when closing the cartridge.
[0010] According to some embodiments of the present invention, an electrical dissolving mechanism is implemented using an ultrasonic transmitting unit which is associated with the cartridge unit, enabling to transmit an ultrasonic signal toward the ink capsule for initiating the liquefying process of the of ink.

Each cell 203 can be filled with a different ink capsule of a different color, such as: Cyan, Magenta, Yellow and Black. The cartridge unit 202 can slide along rails 506 (as seen in Fig. 5) using sliding elements 204, which are installed at the bottom part of the printer. [0014] Reference is now made to Fig. 3, which is a simplified pictorial illustration showing an internal view of a cartridge unit 300 which includes: a closure arm 301 for supporting the cover at an opened position, sealing ribbons 307 for preventing ink from drying, transparent windows 302 enabling to view the liquid level therethrough, a slot 303 for placing the Printed Circuit Board (PCB) 703 (as shown in Figure 7), an ink nozzle 304 for spraying the ink, located at the lower part of the cartridge unit 300 slightly above the bottom thereof, a container 305, which is used to collect ink overloads, and a sharp projection 306 at the bottom of each container cell for cutting the skin of the ink capsules 701 (as shown in figure 7).
[0015] Once the skin which wraps the ink capsules 701 (as shown in figure 7) is cut, the capsule composition therein starts dissolving, in reaction to the exposure of the capsule composition to air. Within the ink capsule a PCB (Printed Circuit Board) is encapsulated, which includes a code for controlling the activation of the printer. The PCB cannot be removed from the ink capsule before the composition thereof liquefies. The PCB code determines limits for activating the printer in terms of remaining ink level, time period, number of prints etc. Once the limit is reached the printer cannot be activated before a new PCB is released from a new ink capsule. The PCB therefore may include one or more sensors for sensing the remaining volume or weight of the ink in the cartridge cell.
