Abstract
Techniques for packaging inkjet style ink cartridges which prevent ink seepage without dedicated nozzle pressing mechanisms, nozzle sealants, or adhesives. Specifically, the ink cartridge is circumscribed by a flexible, multifaced cartridge holder which is then placed in an aluminum bag and vacuum packed. Integral, ink impermeable nozzle compressing and cartridge terminal coverage components are disposed on the inner periphery of the cartridge holder and engage the respective cartridge ink ejection and terminal areas when the cartridge holder is folded around the ink cartridge. Vacuum packing forces the outer aluminum bag to constrict and compress the cartridge holder, thereby securing the cartridge and sealing off the ejection area through compression of the aforementioned compressing and coverage surfaces. As a result, the ink cartridge can be packaged without the use of any adhesive materials, and the sealing performance can be significantly improved using a simple packing method.
