  • Patent number: 6644516
    Abstract: A manually operated liquid foaming dispenser is attached to the top of a container of liquid and is manually vertically reciprocated to dispense the liquid from the container as a foam. The dispenser includes a liquid pump chamber and an air pump chamber that respectively pump liquid and air under pressure to a discharge passage of the pump where the liquid and air are mixed, generating the foam dispensed from the dispenser. The air pump chamber has a tube valve controlling the discharge of air from the air pump to the discharge passage, and the air pump chamber is charged with air by opening the air pump chamber to the exterior environment of the dispenser.

  • Patent number: 6540107
    Abstract: A self defense ring device which ejects a noxious substance in the direction of an assailant when activated by a user. The invention includes a sealed ampoule containing a noxious substance or a combination of substances separated by membranes. This ampoule is driven forward by pressure within a closed chamber having an ejection outlet. The ampoule is pierced and collapsed by the pressure, ejecting the noxious substance or mixture of substances through the ejection outlet at high speed. This mechanism is appropriate for a wide variety of noxious substances. The ejection outlet is inconspicuously placed on the side or underside of the ring, aiding in concealing the self-defense function of the ring device.

  • Patent number: 6540117
    Abstract: A dispenser for dispensing metered amounts of a viscous liquid includes a liquid reservoir and a pump chamber having an opening in communication with the reservoir. A dispensing orifice is defined in the pump chamber. A pump mechanism is configured with the pump chamber and is movable from a rest position to a pressurizing position upon actuation thereof to pressurize liquid within the pump chamber. A check valve mechanism is disposed in the opening. A sealing member is disposed within the pump chamber to seal the dispensing orifice upon an initial movement of the pump mechanism to its pressurizing position. The sealing member is moveable within the pump chamber upon subsequent further movement of the pump mechanism to its pressurizing position to unseal the dispensing orifice.

  • Patent number: 6499898
    Abstract: An assembly is provided for dispensing a viscous fluid substance which can include a paste or a gel. The assembly includes a receptacle of variable volume containing the substance to be dispensed, and the dispensing is effected with an airless pump which comprises a pump body that communicates freely with the inside of the receptacle, and an outlet member through which the substance is discharged. The dispensing is effected with a dispensing head provided with dispensing channels which are open to the outside and which are fed via the outlet member of the pump. The assembly is characterized by the fact that the dispensing head comprises (1) a backplate which is provided with (a) an assembly system for assembling it onto the pump outlet member and (b) an opening facing the pump outlet member, and (2) an applicator element which is secured to the backplate, which is disposed on the other side of the backplate from the receptacle, and which is provided with openings that open towards the outside.

  • Patent number: 6488177
    Abstract: A method and apparatus for fusing a pour spout to the surrounding surface of a lid or container during the molding process. During molding the hot molten plastic of the lid or container contacts a relatively thick rim portion at the bottom of the pour spout to meet the thick rim portion and create fusing during the cooling of the mold. The pour spout has a flexible section to permit a portion of the fused pour spout to be moved between collapsed and extended positions.

  • Patent number: 6471098
    Abstract: The invention is related to the structure of an adhesive dispenser that is composed of an outer tube with a push rod and a handle. The apparatus uses a certain number of elastic elements to make relative displacement between push rod and outer tube, while it uses the locking end of the push rod and cotter groove to perform functions like locating, acceleration and stepwise movement, which makes easy operation for the users. Moreover, in the apparatus the outer tube can be equipped with an inner tube. So the spacing between inner tube and outer tube provides a mechanism that the sealant and adhesive filled in-between the inner and outer tube will flow out and mix under the motion of the push rod. This mechanism will not only facilitate sealing, adhesion and hardening prevention, but will also provide reusability.

  • Patent number: 6457609
    Abstract: The cartridge dispenser comprises a double cartridge having two cylindrical containers of different cross-sections, a drive for a dynamic mixer, and a housing base in which the drive shaft of the dynamic mixer is arranged in a longitudinally displaceable manner. The mixer drive shaft is guided in a laterally displaceable manner such that the driver of the mixer drive shaft is situated on the center axis of the mixer rotor independently of the cross-sectional ratio of the containers of the double cartridge. The mixer is located on the center axis which extends between the outlets of the containers. The mixer drive shaft is automatically forced to the correct position when a double cartridge is inserted. Consequently, the driver is always correctly aligned to the mixer rotor. Suitable means in the housing base always provide a correct location of the cartridges, and in a preferred embodiment, the mixer can be attached to the cartridge without the need of being previously oriented.

  • Patent number: 6425497
    Abstract: A method and apparatus for dispensing a resist solution used in a semiconductor device manufacturing process senses the presence of air bubbles in the solution during delivery through a line feeding a dispensing pump. Air bubbles in the line are sensed by an optical photocoupler that senses changes in the intensity of light refracted through the solution caused by air bubbles entrapped in the solution. The sensor produces an air bubble indicating signal that can be used to activate an alarm or to stop the dispensing process.

  • Patent number: 6371336
    Abstract: The electrically operated dispensing appliance comprises a gear motor which is connected to the main shaft by a first gear and a first shifting sleeve in order to operate the advance and the relieving stroke under high loads, and for the operation at smaller loads, i.e. fast retraction and fast forward feed, it is connected to the main shaft by a second gear, a driving shaft, and a second shifting sleeve. An electromagnet is connected to said two shifting sleeves in such a manner that one or the other shifting sleeve is selectively connectable to the main shaft. A drive assembly of this kind is more economical and more silent than a solution with two gear motors.

  • Patent number: 6276565
    Abstract: An object sensor (18) detects an object such as a hand (20) and operates a valve (52) that permits liquid soap (86) to flow from a disposable soap container (12). The liquid soap is typically quite viscous but tends to be expelled because of pressure applied from a carbon-dioxide cartridge (32). A pressure-regulator assembly (40) permits gas from the carbon dioxide cartridge (32) to enter the soap container (28) only so long as the soap container's internal pressure is less than a predetermined maximum.

  • Patent number: 6257445
    Abstract: A fluid dispensing apparatus for dispensing a viscous fluid from a source of viscous fluid onto a substrate. The dispensing apparatus includes an electrically operated, normally-opened, dispensing valve having an inlet in fluid communication with the source of fluid and a shut-off valve fluidly connected between the inlet of the dispensing valve and the source of viscous fluid. The shut-off valve has a normally-closed state interrupting fluid communication between the source of fluid and the inlet of the dispenser body, thereby inhibiting the normally-opened dispensing valve from dispensing fluid when power is removed from the dispensing apparatus.
