20140176649 | REPLACEABLE INK BAG AND INK CARTRIDGE WITH REPLACEABLE INK BAG - A replaceable ink bag and an ink cartridge with replaceable ink bag are provided. The ink bag includes an ink amount trigger, a bag body and a positioning element. The two opposite sides of the bag are partially adhered with the ink amount trigger and the positioning element respectively. The ink cartridge includes a cartridge body, an ink bag and a lid body. The lid body is removably engaged to the cartridge body to house the ink bag. The wall on long side of the cartridge includes at least a retention block. The surroundings of the positioning element of the ink bag are disposed with at least a retention element. The retention element can be inserted between the retention block and the bottom of the cartridge body for fixing the ink bag inside the cartridge. | 06-26-2014 |
20130190421 | LOW ODOR ENVIRONMENTALLY-FRIENDLY NANO-PIGMENT INKJET INK COMPOSITION - A low odor environmentally-friendly nano-pigment inkjet ink composition has good storage stability, inkjet stability, and good print quality. The printhead nozzles are not easily clogged by such an inkjet ink composition. The printed image has high gloss, scratch resistance, and weather resistance. The inkjet ink composition using low toxic and low odor raw material has a high flash point, and has high security to human health and environment. The inkjet ink composition can meet both the environmental requirement and the print quality requirement. The inkjet ink composition includes 1-10% of N-ethyl pyrrolidone, 1-20% propylene carbonate, 50-80% glycol ether solvent, pigment, dispersant, resin, plasticizer, surfactant, and cyclic tertiary amine compound as an acidity regulator. | 07-25-2013 |
20120252948 | QUICK-DRYING AND COATING-FREE INKJET INK COMPOSITION - A quick-drying and coating-free inkjet ink composition is provided, including a solvent, a colorant, a resin, a plasticizer, and a surfactant. The solvent is selected from the group consisting of aliphatic alcohols, alcohol ketones, ethylene glycol ethers, and propylene glycol ethers, and all have more than two carbon atoms in a molecule. The colorant is dissolved or dispersed in the solvent, and the amount of the colorant is 0.1 to 20% by weight of the total weight of the composition. The resin is used to adjust the viscosity of the inkjet ink composition, and the weight ratio of the resin to the colorant is 0.5:1 to 5:1. The plasticizer is used to increase redissolution of the resin, and the weight ratio of the plasticizer to the resin is 0.01:1 to 5:1. The amount of the surfactant is 0.01 to 2.0% by weight of the total weight of the composition. | 10-04-2012 |
20110141210 | INK CARTRIDGE APPARATUS FOR CONTINUOUSLY SUPPLYING INK - An ink cartridge apparatus for continuously supplying ink is provided, including a connection device, an exposed chip socket and a filtering device on an ink cartridge main body. The connection device is for connecting to an ink bottle and the filtering device is for filtering the impurity from the ink flowing from the ink bottle into ink cartridge main body. The exposed chip socket is for the user to replace the chip more conveniently. With the ink supply mechanism of ink bottle into ink cartridge main body, the ink cartridge main body can maintain good ink quality and when the threshold set by the chip is exceeded, the replacement of the chip can be done without removing the entire ink cartridge from the printer so as to achieve the object of continuously supplying ink. | 06-16-2011 |
20100201761 | UNINTERRUPTED INK SUPPLY SYSTEM - An uninterrupted ink supply system is provided, including a main cartridge connected to a printer, a connection device having an automatic airflow control structure and installed on said main cartridge, and a replenishment cartridge for connecting to the connection device. The replenishment cartridge is connected to the connection device, and is able to refill the ink into the main cartridge, and automatically stop refilling when the ink level reaching a specific height and start refilling again when ink level below a specific height. When the replenishment cartridge is removed for refilling when the ink is used up, the main cartridge still contains ink so that the printing will not be suspended. | 08-12-2010 |
