Latest Patents

Barlow holds a patent for a collapsible storage bladder designed for ink cartridges. This improved ink storage system allows for rapid and continuous operation while effectively avoiding deprimes. The flexible and resilient ink bladder features an elongate reservoir that is closed at the bottom and open at the top, with a tubular side wall in between. The bladder is supplied with ink, and a negative pressure is maintained within it. This negative pressure causes the side wall to collapse inwardly during ink delivery. To ensure proper collapse, the bladder's side wall thickness varies, with some portions being thinner than others. This design prevents undesired increases in back-pressure, thereby eliminating ink cartridge deprimes.
