  • Publication number: 20190257452
    Abstract: The clamping clip described here includes a clamping band the two end portions of which overlap each other in the closed condition of the clamping clip. A tongue disposed on the overlapped inner band portion is received by a tongue channel provided on the overlapping outer band portion, the shape of the tongue channel being complementary to the shape of the tongue. The tongue has a root part in which the tongue width, measured in the axial direction of the clamping clip, decreases from the full clamping band width to a smaller value, and an end part adjoining the root part, in which the tongue width constantly has the smaller value.

  • Patent number: 9173381
    Abstract: A nectar feeder for birds. The nectar feeder has a container for storing nectar feed. A base tray is attached to the container and connected in fluid communication with the container. A float is positioned between the container and the base tray. A ball is positioned on the float. The ball regulates the fluid communication between the container and the base tray. In operation, the nectar feed flows through the container and into the base tray until the float rises to a level where the ball prevents fluid from flowing into the base tray.

  • Patent number: 9004007
    Abstract: A nectar feeder for hummingbirds is disclosed. The feeder includes a container configured and arranged to store nectar feed. A spout depends from the bottom end of the container with an exit port defined thereon. A base tray positioned below the container and contains nectar feed. A vertical member extends from the base tray. A float engages at least one vertical member to prevent substantial independent lateral movement of the float within the base tray. The float also includes a rounded bottom surface to further help stabilize it on the liquid feed to prevent leaking. The float has a stopper therein positioned below the spout. In operation, the nectar feed flows through the container and into the base tray until the float rises to a level where the stopper engages the exit port on the spout to prevent fluid from flowing into the base tray.

  • Patent number: 8651054
    Abstract: A bird feeder has a body member, a base, and at least one feed port member. The body member is used for storing bird food having a top end, a bottom end and a sidewall with the sidewall of the body member defining at least one feeding aperture. A base is attached to the bottom end of the body member to prevent bird food from exiting the body member. The at least one feed port member is interfittingly engaged within at least one feeding aperture. The port member includes a frame member and a mesh insert attached to the frame member. The feed port member is releasably secured within the feeding aperture of the body member. In operation, the feed port member can be easily removed from the body member for easy cleaning or adapting to a particular bird feeder construction.
