  • Patent number: 8246883
    Abstract: A filter cartridge includes a one-piece housing having a port and a filtration element disposed in the housing. The filtration element is a coherent filter block that can be larger in cross dimension than the port. The filtration element can be a coherent filter block that generally conforms to the shape of the hollow interior, but is slightly smaller than the hollow interior so as to define a gap between the filtration element and the inner surface. One method for constructing a filter cartridge includes providing a housing having a hollow interior and at least one port, introducing a granular material into the hollow interior via the port, and transforming the granular material in the hollow material into a coherent filter block. Another method for constructing a filter cartridge includes providing a filtration element in the form of a coherent filter block, and overmolding a housing around the filtration element.

  • Patent number: 6068371
    Abstract: An ink containment and dispensing device for an ink-jet printer is provided with a main reservoir in the form of a flexible pouch, which is typically maintained at ambient pressure. The main reservoir is coupled to a variable volume chamber via a one-way valve which allows the flow of ink from the reservoir to the chamber and prevents the flow of ink from the chamber to the reservoir. The chamber is coupled to a fluid outlet, which is normally closed to prevent the outward flow of ink. However, when the ink supply is installed in a printer, the fluid outlet establishes a fluid connection between the chamber and the printer. The chamber is part of a pump provided with the ink supply that can be actuated to supply ink from the reservoir to the printer. The pump has a linearly acting pumping member and a flexible diaphragm that overlies the pumping member, the diaphragm being impervious to the transmission of oxygen and moisture therethrough to prevent degradation of the ink within the chamber.

  • Patent number: 5878959
    Abstract: A pump dispenser has a nozzle body on which is rotatably disposed a nozzle cap having two orifices which selectively align with a swirl chamber formed in the front end of the body. One orifice is formed with a surrounding cup-like structure to retain the last drop of liquid after discharge. The other is formed with a pair of diagonal parallel ribs on opposite sides of the orifice to effect an elongated narrow landing pattern for the spray.

  • Patent number: 5662246
    Abstract: A pump dispenser has a body defined by a top wall and a front end and a nozzle cap rotatably mounted on the body. The cap, which must be rotated for the nozzle to operate, has an opening in a side wall thereof adjacent the front end. An elongate blocking tab has a rear portion unitary with and connected to said top wall, and a middle portion extends forwardly from the rear portion and is disposed in the opening in the nozzle cap. The tab also has a forward finger-grippable portion extending forward from said middle portion. The middle portion, by being in the opening, prevents rotary movement of the nozzle cap until the blocking tab is torn from the top wall.
