  • Patent number: 8220669
    Abstract: A material dispensing pump includes a drip prevention system and method so as to avoid undesired dripping of the dispensed fluid. In one example, the fluid path is sealed. Positive pressure is applied to the fluid during a dispensing operation to present the fluid to the auger-style pump at a desired rate. Between dispensing operations, or when dispensing is completed, the fluid is placed in suspension, for example by applying a negative pressure, thereby preventing the fluid from being inadvertently released at the dispense tip. In addition, following a dispensing operation, the pump dispensing controller can be programmed to reverse the rotation of the feed screw, in order to draw the material in a reverse direction and to further suspend the fluid.

  • Patent number: 8091735
    Abstract: An improved concentrated/extract cartridge is provided for dispensing a liquid in an accurate and repeatable manner. The cartridge includes an electromagnetically actuated piston connected to a value. The piston includes an exterior ring supported by a hollow interior web that is configured to permit a flow of fluid into the dispensing tube when the value body is in contact with the value seat. A membrane is located below the web and is in sealing contact with the internal ring when the piston is activated. This allows a precise and repeatable amount of the liquid to be dispensed with each stroke. Dispensers for dispensing the liquid from the cartridge for a number of applications are also provided. The dispensers each include an actuating coil into which the dispensing tube is inserted. A controller is connected to the coil for controlling the actuation of the piston/value assembly for dispensing the fluid in the cartridge as required for the particular application.

  • Patent number: 8016159
    Abstract: A closure for a container having an opening includes a base cap and an overcap that form a chamber adjacent the opening which is sealed from the contents of the container by a frangible membrane having an inclined line of weakness and by a hinge member having a pocket extending downward adjacent lower and upper terminuses of the line of weakness. The overcap includes a cutting member received within the pocket that severs the line of weakness upon substantial rotation of the overcap with respect to the base cap. A pushing member may cooperate with a cam member to deflect open the membrane upon severance. The pocket may include a stop for the cutting member. The base cap may include a cylindrical structure having an upwardly inwardly projection member to form a seal with an thickened upper portion of the overcap skirt to protect against penetration into the chamber.

  • Patent number: 7980425
    Abstract: A pump for metering a liquid is disclosed comprising a flexible tube connected to a container with a pressure relief valve located in the flexible tube. A housing defines an aperture for receiving the flexible tube with a compression surface located adjacent to the aperture. A reciprocating member has a sealing element and a pumping element. A drive moves the sealing element for pinching the flexible tube against the compression surface upstream from the pressure relief valve for trapping liquid between the sealing element and the pressure relief valve. The drive moves the pumping element for collapsing the flexible tube against the compression surface for pumping the trapped liquid to discharge a metered quantity of the liquid from the pressure relief valve.
