  • Patent number: 8506875
    Abstract: A single-sided shuttle-type blow molding apparatus having an extruder for substantially continuously extruding a thermoplastic material in tubular form at a moldable temperature downwardly along a vertical axis. The apparatus includes a mold having a set of mold parts adapted to open and close relative to each other to define, when closed, a mold cavity. A shuttle having the mold mounted thereon is arranged to move along a closed path from a first position wherein the mold engages, when open, a finite length of the thermoplastic tube, to a second position away from the first position. The apparatus further includes a blow head adapted to blow the finite length of the thermoplastic tube to form the container as the mold moves from the first position to the second position of the closed path. The apparatus includes no more than one mold. A method is also described.

  • Patent number: 6893602
    Abstract: Shuttle blow molding apparatus having an extruder for substantially continuously extruding a thermoplastic material in tubular form at a moldable temperature downwardly along a vertical axis. A first finite length of the thermoplastic material is grasped by a first mold set, which then moves outwardly and downwardly with respect to the extruder to provide clearance for a second mold set to move to a position to grasp a second finite length of the extruded thermoplastic tube. The first mold set is then moved horizontally away to permit the finite length of thermoplastic tube therein to be blown into a hollow article, and thereafter removed from the first mold set at a second position of the first mold set.

  • Patent number: 6585359
    Abstract: An ink container for an off-carriage printing system including an ink supply station. The ink container contains a collapsible reservoir filled with ink that is in fluidically connectable to a conduit that leads to a pressure regulator. The outlet of the regulator delivers ink to a printhead. A pressure vessel surrounds the reservoir. The system pressurizes the pressure vessel, which results in pressurized ink being delivered to the regulator. The ink container has a sensor that infers the actual volume of ink in the reservoir by sensing the relative position of the reservoir walls. This sensor is mounted between the pressure vessel and the collapsible reservoir. The sensor is electrically connected to pads that are accessible from the outside of the ink container. Leads route from the pads, through a seal zone, and to the sensor. The seal is provided by a compressed o-ring.

  • Patent number: 6471907
    Abstract: Shuttle blow molding apparatus having an extruder or a blow head for substantially continuously emitting a thermoplastic material in tubular or parison form at a moldable temperature downwardly along a vertical axis. A finite length of the thermoplastic material is grasped by a first mold set, which then moves downwardly with respect to the extruder or blow head to provide clearance for a second mold set to move to a position to grasp a second finite length of the emitted thermoplastic. The first mold set is then moved horizontally away to permit the emitted thermoplastic length therein to be blown into a hollow article, and thereafter removed from the first mold set that is permitted to return and engage an other finite length of the thermoplastic material. The second mold set follows the first mold set in a path of travel traced by the first mold set.

  • Patent number: 6386675
    Abstract: An ink container for holding a supply of liquid ink for use in an inkjet printing system. The container includes a collapsible ink reservoir for holding a supply of liquid ink, and a multiple functioned chassis. The chassis rigidly supports an air inlet for receiving pressurized air from the printing system and an ink outlet for delivering pressurized ink to the system. The chassis supports a collapsible ink container by providing an attach surface over which the collapsible container is attached. The attach surface allows a relatively simple pleated bag construction to be used by providing a surface whose normal is substantially perpendicular to the longitudinal axis of the container. The chassis is adapted to engage with a pressure vessel opening, providing a seal that separates the pressure vessel from an outside atmosphere.

  • Publication number: 20010009242
    Abstract: Extrusion blow molding apparatus (10) having a blow mold (12), a neck mold (14) positioned above the blow mold and an anvil (30) positioned in an outwardly facing cavity (32) of the neck mold. A container (C) is produced in the molding apparatus from a parison of a heated thermoplastic material by introducing pressurized blowing fluid into the container being formed by way of a blow pin assembly (16) that is reciprocable relative to the blow mold. The blow pin assembly has an inner tubular member (20) with a free end that is within the container during blowing, and an outer tubular member (22) that surrounds the inner tubular member and defines an annulus therewith for withdrawing spent blowing fluid from the container. The outer tubular member has radial ports (24) for directing spent blowing fluid against a moil (M) being formed at a rim (R) of a finish (F) of the container.

  • Patent number: 6017118
    Abstract: An ink container for an inkjet printing system is described, including an assembly of a simple housing with caps bearing indicia and protective surfaces to enable effective handling, aligning, keying and latching of the ink container. The ink container includes an ink container housing, the housing including an ink reservoir and a fluid outlet in fluid communication with said reservoir. The fluid outlet is for providing ink to the inkjet printhead. The container further includes a separately fabricated first cap attached to an end of the housing, the first cap having a plurality of mechanical features that provide mechanical functions for the ink container. The end of the housing is a leading end relative to a direction of insertion of the ink container into the printing system. The mechanical functions can include positioning the ink container relative to the supply station, a keying function for preventing installation of an ink container in the supply station without a cap providing the keying function.

  • Patent number: 5962096
    Abstract: A flexible plastic tube and a method of forming a flexible plastic tube includes injection molding a finish having an opening, extruding a tube integrally with the finish by relevant movement of the finish with respect to an extruder, moving the finish axially away from the extruder while continuing continuously extruding the tube, closing a blow mold about the extruded tube, blowing the tube into an integral container body having a closed bottom, opening the molds to provide an integral flexible tube with a finish thereon. Thereafter the method includes decorating the body with indicia, cutting the closed end of the tube leaving an open-ended tube of the end opposite the finish, and applying a closure to the finish. Subsequently, the tube is filled through the open end and the open end is closed. The decorating includes rotating the tube about the longitudinal axis of the tube while engaging the finish and bottom.

  • Patent number: 5869155
    Abstract: A hollow plastic container having a finish which has a diameter less than the diameter of the body portion of the container which is made by forming a parison with a neck portion for defining the finish and a body portion and thereafter expanding the body portion to a cross section greater than the cross section of the neck portion. The neck is then trimmed by removing plastic material from the outside of the neck and from the top of the neck to form the finish to the final dimensions. In one form, the parison is a multi-layer parison in order to form a multi-layer plastic container.
