David C. Crampton has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6086812
    Abstract: A multiple hole, preferably a two hole spray dispensing system and sprayer in which colliding streams of viscous liquid are dispensed to the atmosphere are provided. The spray dispenser includes a reservoir for storing a fluid product. An aerosol or manually pressurized dispensing system preferably a hand held dispensing system may be used. Liquid is delivered from the reservoir under pressure to a delivery passageway. A nozzle having two or more outlets to the atmosphere is mounted to the delivery passageway to provide colliding streams of fluid.
    Type: Grant
    Filed: December 31, 1998
    Date of Patent: July 11, 2000
    Assignee: Par-Way Group, Inc.

Liquid is delivered from the reservoir under pressure to a delivery passageway. A nozzle having two or more outlets to the atmosphere is mounted to the delivery passageway to provide colliding streams of liquid. Baffles are provided to disrupt the flow of liquid in the stream prior to the collision of the streams to provide an improved spray pattern.

  • Patent number: 5779156
    Abstract: A spray dispenser for dispensing and atomizing viscous liquids and a system for dispensing same is provided. The dispenser includes a reservoir for storing a viscous liquid. The viscous liquid is delivered under pressure from the reservoir to a delivery passage. A nozzle is provided with two opposed outlets to the atmosphere which provides intersecting streams of viscous liquid during dispensing.

  • Patent number: 5667138
    Abstract: According to the invention, a hand held sprayer is provided. Fluid flows from a reservoir to a delivery passageway upon pulling or pressing an actuator such as an aerosol actuator or button, a trigger or finger pump button. A nozzle having an inlet and an outlet is rotatably mounted to the outlet of the delivery passageway. The nozzle rotates about a rotation axis through the center of the discharge end of the nozzle. The actuator of the hand held sprayer is interconnected to the rotatably mounted nozzle to provide rotation of the nozzle simultaneously with the dispensing of the liquid from the reservoir to the atmosphere. The nozzle rotates from about 90.degree. to 360.degree. about the axis of rotation. The resulting hand held sprayer is capable of dispensing viscous liquids having a viscosity of over 60 cps and delivering a desirable round spray pattern.

  • Patent number: 5492275
    Abstract: The hand pump sprayer and system for dispensing viscous liquids are provided. A nozzle is rotatably mounted around the delivery passageway of a hand pump sprayer. The nozzle is interconnected to the trigger of the hand pump sprayer so that the nozzle rotates, upon pulling of the trigger, simultaneously with the discharge of the liquid to the atmosphere. The nozzle rotates about an axis of rotation through the center of the discharge end of the nozzle through an angle of rotation from about 90.degree. to about 360.degree., desirably from 180.degree. to 360.degree. and preferably 270.degree. or more. Desirably the nozzle has two discharge outlets which direct fluid expelled from the hand pump sprayer along intersecting discharge axes. Simultaneously as the fluid is discharged along the intersecting axes, the nozzle is rotated about the axis of rotation. The resulting dispensed liquid has a high degree of atomization and a desirable round spray pattern.
