  • Patent number: 6585136
    Abstract: A paste dispenser includes a housing which has two angularly spaced vanes which rotate about an axis. The two vanes and a contoured surface form a paste-receiving chamber. Paste is forced into the dispenser under pressure from a paste container such as a toothpaste tube. The paste fills the paste-receiving chamber, and continued pressure causes the contents of the paste-receiving chamber to be deposited at an opening where it can be claimed by a user.

  • Patent number: 6428381
    Abstract: A flying device which rotates as it travels through the air includes a body having three radially projecting vanes. Three blades or wings are pivotally connected to the three vanes. Each blade may be selectively and adjustably attached to an adjacent vane so that the blade projects outward from the body. When the flying device is thrown, the blades cause the aerial device to spin in a twirling motion. For storage or shipping, the blades may also be folded over so that they abut the body.
