  • Publication number: 20090071014
    Abstract: A flexible strip trimmer device with a housing capable of holding an axle on one end, a circular cutting blade having a rotatably operable circumferentially extending cutting edge, the blade being mounted for rotary motion on the axle, a fastening to anchor the cutting blade to the axle at the outwardly directed outer end of the axle, the housing having a stop to guide the motion of the blade along the desired axis of motion for cutting, a recess in the stop in the cutting blade's radial plane which is sized to receive a portion of the cutting edge of the blade, the cutting blade traversing the recess so that a portion of it extends into the stop, and a handle attached to the housing.

  • Publication number: 20030082278
    Abstract: A closure for enclosing a flexible container that may contain any type of product. The closure is composed of a collar element that surrounds the flexible container and can have one of several projections extending therefrom. The open end of the flexible container is compressed by use of an apparatus once a desired product is contained therein. The compressing apparatus contains two mateable die elements that, when engaged with each other, form an annular cavity or socket that surrounds the flexible container. Molten thermoplastic material is then injected via an inlet port to surround the flexible container and harden to form a collar.

  • Patent number: 4744170
    Abstract: An animal trap suited for trapping rodents comprising an elongated container having a curved bottom surface and a vertically translatable gate for selectively enclosing an opening in one end of the container after the animal has entered the trap. When set, the trap rests on one end of the bottom surface by gravity with the gate held elevated from the container to permit an animal to enter the trap. When the animal travels toward the opposite end of the container toward the bait remote from the opening, the weight of the animal causes the container to rotate elevating the open end of the container, releasing the gate thereby closing the opening to the container and trapping the animal therein. The gate remains closed by gravity acting downward thereon.
