An enclosure for an ink reservoir bag in an ink delivery system for an ink cartridge comprises a tray and a cover for the tray. The tray includes a bottom wall having opposite ends and opposite sides, end walls extending upwardly from said bottom wall at the opposite ends and side walls extending upwardly from the bottom wall along the opposite sides. One of the end walls of the tray has a pair of openings therethrough between the side walls to receive fill and exit ports of the reservoir bag.

Enclosure for ink reservoir bag

An ink jet cartridge comprising a housing having a print head portion including a nozzle plate having opposed pairs of side edges, rows of nozzles and at least one row of slots between said rows of nozzles and which plate is initially attached to the head portion by beads of an adhesive material overlying the edges of one pair of the opposed pairs of side edges is prepared for renovation by applying a reinforcing bead of an adhesive material to overlie at least one of the other pair of the opposed pairs of side edges and the at least one row of slots. The beads may be a single bead or segmented and are applied by robotic glue applying apparatus.

Renovated ink jet cartridge and method of renovating

An ink reservoir bag of flexible, plastic sheet material for an ink delivery system for an ink cartridge is constructed of two sheets of plastic material having peripheral edges bonded together to provide an ink chamber therebetween and has separate fill and exit ports opening into the chamber and respectively defined by a fill tube and an exit tube bonded to the bag between the peripheral edges thereof. Flexible tubing is connected to the exit port through a check valve interposed between the port and tubing, and a lure lock is interconnected with the fill tube to provide an injection sight for filling the bag. The bag is filled by connecting the tubing to a vacuum source, evacuating air from the bag and tubing, connecting the fill port to a source of ink and using the negative pressure to draw ink into the bag and tubing.

External ink supply bag and method of filling the same

An ink jet cartridge comprising an outer housing and an inner ink chamber has adjacent housing and chamber wall portions, and a coupling member for communicating the ink chamber with an external source of ink has an inner end extending through an oversized opening in the housing wall portion and into threaded interengagement with an opening through the chamber wall portion. The outer end of the coupling is outside the housing wall portion for connection to a source of ink.

Tube coupling for ink jet cartridges

An ink jet cartridge for use in a continuous cartridge refill system has a top side, a front side, and a handle at the juncture therebetween. A flexible ink supply tube for connecting the cartridge with an ink reservoir extends through openings in the handle of the cartridge and is connected to a fitting on the top side of the cartridge which communicates the supply tube with the ink chamber of the cartridge. Routing of the tube through the handle provides strain relief for restraining the application of a pulling force on the tubing at the point of connection thereof with the coupling.

An ink container opener having a first member having an opening formed therein; and, a second member received within the opening of the first member. The second member further has an opening for receiving an ink container for separating a top portion from a bottom portion of the ink container.

Ink container opener with multiple inserts for different container types

An ink container opener has a base member having an opening for receiving a cap of an ink container and a holder member which is inserted over a body of the ink container. The holder and base member each has a first arm and a second arm substantially perpendicular to said first arm. The holder member first arm has an opening for receiving a second portion of the ink container. The base member opening and the holder member opening are substantially parallel to each other when the ink container is mounted within the opener. Force is applied to the holder member to separate the cap from the ink container body.

Ink container opener

An ink container opener has a first portion and a second portion which are approximately perpendicular to each other. Each portion has an opening for receiving an ink container cap. The opening of the first portion comprises a plurality of ridges extending along at least one side of the opening. The first and second portions are formed of a unitary construction and form an L-shaped configuration. Force is applied to the container body to separate the cap from the body as the cap is supported by the opener.

Ink supply bag

An ink container opener has first and second portions approximately perpendicular to each other to form an L-shaped opener. The first portion has an opening having a plurality of ridges extending along opposite sides of the opening. An ink container is received within the opening and force is applied to the ink container to remove a cap from a body of the ink container.

An ink ribbon cartridge has a take-up spool () with an opening having a plurality of drive surfaces () and slip surfaces (). The take up spool is preferably of a one-piece construction. A first spindle with a cantilever member () and a tab () extending therefrom is mounted on the take-up spool. When the drive surface engages a tab of the spindle, rotation of the spindle rotates the take-up spool. When one of the slip surfaces engages the tab of the spindle, the spindle rotates relative to the take-up spool.

Clutch mechanism with one piece plastic spool

An ink cartridge includes a housing, an ink ribbon ( ), spools ( ) for holding the ribbon, and spindles ( ) received within openings of the spools. The housing has semi-cylindrical sections ( ) which receive the spools. The housing further includes c-shaped sideplates ( ) with openings for each spindle. The c-shaped sideplates selectively expand to receive the spindles and retain the spindles in position.

Ink ribbon cartridge with C-shaped sideplates

An ink cartridge has a pair of sideplates ( ) which connect a first portion ( ) of the housing to a second portion ( ). The sideplates expand to allow spindles ( ) and spools ( ) to be installed within openings of the housing. The sideplates are spaced apart and are generally parallel to each other. The sideplates are pulled in opposing directions from a first dimension between the sideplates to a second dimension slightly greater than the first dimension.

Ink ribbon cartridge with expandable sideplates

An ink ribbon cartridge has first and second tubes ( ) for holding an ink ribbon. The tubes have slots formed in each end. Spindles ( ) are attached at the ends of the tubes. The spindles have a disk portion and an end which is received by tube slots. One of the spindles has a cantilevered member ( ) which engages a slot of a tube and allows rotation of the tube in only one direction. The cantilevered member has an end having a radial edge ( ) and a ramp ( ) adjacent the straight side. Rotation of the spindle in one direction abuts the radial edge against a wall of the slot thus providing a positive drive and allowing rotation of the tube with the spindle. Rotation of the spindle in a second direction opposite to the first direction causes the ramp side to contact and slide along a wall of the slot, thus deflecting the cantilevered member inward toward the center of the spindle.
