  • Patent number: 7163130
    Abstract: A caulking gun has a tubular chamber to surround sleeve-like rigid tubes and compressible sausage type containers containing viscous materials including sealants, adhesives, caulking, mastics and the like. When rigid tubes are loaded into the chamber, compressed gas is allowed to surround the sleeve and a plunger loaded within the rigid tube to equalize pressure around the outside of the rigid tube. If a sausage type container is loaded into the chamber, a removable plunger is also provided to form a tight seal between the perimeter of the plunger and the inner surface of the chamber. Compressed gas introduced into the chamber preferentially acts on the plunger and an underlying end wall of the sausage to expel the material, without imparting any significant pressure to other parts of the sausage. The caulking gun includes a variable flow rate nozzle which may be removed from the device. The nozzle may be replaced with similar or different nozzle pieces of various shapes and sizes, if desired.

  • Patent number: 6994126
    Abstract: A squirt gun includes a hollow housing in the form of a gun with a liquid dispensing assembly within the housing. The liquid dispensing assembly includes a rigid pressure vessel having either a gas-filled compressible bladder or a spring-loaded piston disposed within. The vessel is connected to a flexible tube with a nozzle at one end, and the gun is adapted to receive and expel water to and from the vessel through the nozzle. A pivotable trigger cooperates with the flexible tube to either enable both the receiving and expelling, or to deny the expelling of the water. To fill the gun, water is forced into the vessel under pressure, which compresses the air bladder or the piston to retain that pressure within the water-filled vessel. To expel the retained water, the trigger is moved to an “open” position, which allows the water to be forced from the pressurized water-filled vessel, through the nozzle, and from the gun as the air bladder or the piston expands.

  • Patent number: 6910603
    Abstract: A dispenser pump has a fixed spout (15) on an upper component (10) which is rotatable relative to a lower component (11) adapted to be fitted to a container (not shown). For transport and storage the spout (15) is rotated so that its inner opening is obturated by the distal end of an arm (13) of the lower component which circumferentially divides its discharge compartment (31). Simultaneously an air opening (22) of the upper component is obturated by the arm (13) which also circumferentially divides an annular air chamber (32) below the discharge compartment (31). The compartment (31) and air chamber (32) are separated by an annular barrier seal (23) in rubbing contact with the internal wall of the upper component (10). By this provision the danger of leakage is so much reduced that it is not necessary to provide a mechanical lock for the pump when the dispenser is closed.

  • Patent number: 6702156
    Abstract: A liquid jetting pump of the present invention is constructed such that an intra container liquid is sucked into a cylinder 3 through a suction valve 9 by moving a vertically movable member 4 up and down, and the intra cylinder liquid is jetted out of a nozzle 29 through a discharge valve 31 from a stem 28. A plurality of ribs 10 are protruded in a peripheral direction from a lower edge part within the cylinder. Engagement recessed portions 11 are formed in inner parts of the upper surfaces of the ribs. A lower edge of a coil spring 38 for biasing the vertically movable member 4 is secured to each of the engagement recessed portions 11, thereby permitting a flow of liquid on both sides of the lower edge of the spring internally externally.

  • Publication number: 20040004092
    Abstract: A valve apparatus for controlling the discharge of material pumped by a material pump through a discharge hose, wherein the valve apparatus includes a substantially sealed flexible bladder in a casing to be located about a discharge hose, and a source of compressed air. Material flow through the discharge hose is prevented by introducing compressed into the flexible bladder, causing the bladder to expand and constrict the discharge hose, and the flow of material is resumed by deflating the bladder. Simultaneous control of the material pump and the valve apparatus is also achieved by the present invention.

  • Patent number: 6669061
    Abstract: A pump dispenser which precisely transmits trigger motion and enables stable operation of a piston section. The manually operable pump dispenser is mounted on a vessel wherein the liquid contained in the cylinder section is compressed with a piston section by the displacement of a trigger structure and is ejected through a nozzle orifice. The dispenser includes a base body fixed on the vessel orifice via a packing structure, a cylinder section and a vent cylinder section formed adjacent to each other on the base body, and a trigger structure including a trigger section, a valve casing section mounted on the base body, and a trigger guide section oscillating in the vent cylinder section.

  • Patent number: 6655555
    Abstract: A paint dispensing system including a container having a moveable piston contained therein wherein a paint containing area is defined between the piston and a portion of the container. A dispenser extends through an opening formed in the piston and by moving the piston against paint contained within the container results in paint being forced into the dispenser where the paint moves through the dispenser and through the piston to an outlet where the paint is dispensed.

  • Patent number: 6651702
    Abstract: A squirt gun includes a hollow housing in the form of a gun with a liquid dispensing assembly within the housing. The liquid dispensing assembly includes a rigid pressure vessel having either a gas-filled compressible bladder or a spring-loaded piston disposed within. The vessel is connected to a flexible tube with a nozzle at one end, and the gun is adapted to receive and expel water to and from the vessel through the nozzle. A pivotable trigger cooperates with the flexible tube to either enable both the receiving and expelling, or to deny the expelling of the water. To fill the gun, water is forced into the vessel under pressure, which compresses the air bladder or the piston to retain that pressure within the water-filled vessel. To expel the retained water, the trigger is moved to an “open” position, which allows the water to be forced from the pressurized water-filled vessel, through the nozzle, and from the gun as the air bladder or the piston expands.

  • Patent number: 6637625
    Abstract: A continuous operation metering valve, based on true volumetric positive displacement technology, uses an innovative dual rack and drive pinion design that enables the valve to dispense from one meter chamber while the other meter chamber is filling. This provides greater dispense cycle rates because it does not require a fill or reload period. With an optional encoder-controlled motor, the inventive metering valve is capable of almost unlimited precision dispensing with “on-the-fly” adjustment capability. The metering valve is easily disassembled and cleaned, using stainless steel wetted path components and Teflon seals for the widest range of chemical compatibility. An integral electronic board, mounted to the side of the valve, may be utilized to control the 4-way directional valve and motor direction (when not using a rotary encoder control).

  • Patent number: 6547107
    Abstract: A filling amount adjustment device for a liquid-form substance filling machine, the device including first sliding units disposed on a swing arm and connecting links pivotally attached at one ends to connecting pins of first sliding members (of the first sliding units) that slide along the length of the arm. Second sliding units are disposed on both sides of the swing arm, and the other ends of the connecting links are pivotally connected to the connecting pins of second sliding members (of the second sliding units). Connecting rods connected to piston rods are pivotally connected to the connecting pins. When fine adjustment shafts in which male screws are cut are rotated, the second sliding members are moved and positioned; as a result, the first sliding members slide via the connecting links, thus changing the positions of the connecting pins in the direction of length of the arm.
