  • Patent number: 10695791
    Abstract: A method of applying a viscous material to a fastener comprises aligning a nozzle relative to the fastener by engaging an aligner with the fastener. Engaging the aligner with the fastener comprises positioning the aligner over the fastener and advancing a biasing tube toward the fastener to establish contact between the aligner and a structure to partially retract the aligner into the biasing tube until a plurality of surfaces of the aligner contacts one or more outer surfaces of the fastener. A flexible wall of a dispenser bellows is deflected by expanding a pressure-application device, which is configured to apply pressure on the flexible wall of the dispenser bellows, wherein the dispenser bellows is in fluid communication with the nozzle. The viscous material is expelled from the dispenser bellows responsive to deforming the flexible wall.

  • Patent number: 10098510
    Abstract: A dispenser includes a housing, an aperture within the housing, a receptacle within the housing, and a pneumatically driven actuator. The receptacle removably receives a reservoir, such that when the reservoir is received by the receptacle, an outlet port of the reservoir is exposed through the aperture. When the pneumatically driven actuator is actuated, the pneumatically driven actuator provides a dispensing force that induces a flow of a predetermined volume of fluid within the reservoir through the exposed outlet port of the reservoir and dispenses the predetermined volume through the aperture. In some embodiments, the dispenser includes an internal pneumatic source. The internal pneumatic source may include an air compressor. The dispenser may include a pneumatic input port that receives a pneumatic hose. The dispensing force translates a piston in the reservoir a predetermined distance. The predetermined distance may be linearly proportional to the predetermined volume of dispensed fluid.

  • Patent number: 8870093
    Abstract: A pneumatic dispenser for dispensing viscous material, for example, mastic caulk, from a container is described. The dispenser comprises a fluid supply arrangement for accepting a dispensing nozzle of the container and providing a flow of pressurized fluid to the dispensing nozzle to enable the material to be dispensed as a spray. A moveable member can be used to control the flow of pressurized fluid, for example a member disposed on a cap for closing a container containing compartment of the dispenser and/or a moveable member disposed around the dispensing nozzle. The arrangement of the fluid supply arrangement allows for convenient control of the pressurized fluid flow for spraying the material. Also disclosed is a dispenser with a readily exchangeable pressure application interface for applying a dispensing pressure to the container, enabling the dispenser to be used with both cartridge and foil pack containers.

  • Patent number: 8857674
    Abstract: A pump driver, a disposable pump cartridge for use with the pump driver and a beverage dispenser employing the pump drive are disclosed. The disposable pump cartridge comprises at least one barrel 20 having an inlet valve 24 and an outlet valve 26 associated therewith. A piston 28 movable within the barrel 20 is retained in a minimum volume position during transit by a protrusion 22 on the internal surface of the barrel 20. The piston 20 has a piston shaft 28 with a hollow end arranged, in use, to releasably engage a piston driver to drive the piston 28 from its minimum volume position to an operative position, and to reciprocate the piston 28 within the barrel 20 in its operative position to draw fluid into and pump fluid from the barrel 20 via the inlet valve 24 and outlet valve 26 respectively. Methods of engaging, disengaging and changing the disposable pump cartridge are also disclosed.

  • Patent number: 8857668
    Abstract: A discharging device for discharging liquids includes an outer housing encompassing an inner chamber, a liquid storage receptacle, a discharge orifice, a delivery device for delivering liquid from the storage receptacle to the discharge orifice, a cap that covers the discharge port orifice when present on the outer housing in a safety position, and a manual actuator adapted to actuate the delivery device and which is movable relative to the outer housing between a neutral relative position and an actuated relative position. The cap and the manual actuator cooperate so that displacement of the manual actuator is mechanically blocked when the cap is in its safety position. A locking element that is movable in relation to the outer housing is constrainedly coupled with the movement of the manual actuator and extends in the actuated position through a hole in the outer housing to a region that the cap blocks when mounted in its safety position.

  • Publication number: 20140252044
    Abstract: This invention relates to a discharge device of the dispenser gun type, which is suitable in particular for discharging semi-solid materials such as e.g. bone replacement materials. The discharge device comprises an adapter (400) which is removably attached to a main body (110) of the discharge device. A fastening structure for attachment of a container (300) is formed on the adapter substantially along a proximal direction (C) contrary to the feed direction (A). As a result various types of containers can be fastened to the machine without the need to change the mechanism of the device. The container can be provided on both ends with identical external threads and can be closed by closure caps in order to enable intuitive handling. In order to improve access to points which are difficult to reach, the container may be in the form of a curved pipe or may be formed flexibly. The piston rod (200) of the discharge device is then also formed flexibly.
