Abstract
A spacer is incorporated into the standpipe of a foam-ink-containment type of inkjet print cartridge for retarding the growth of a diffused-air bubble in the standpipe, thereby extending the shelf life of the cartridge by ensuring the bubble will not become so large during storage of the cartridge that the bubble occludes flow of ink to the printhead.
