  • Patent number: 6635272
    Abstract: A dressing and method of treating wounds is provided. The dressing can comprise water-soluble or swellable polymers capable of forming viscous aqueous or non-aqueous solution and form a gel, and which may be dehydrated and milled to form a powder. The dressing can be constructed in the form of a sponge or sheet impregnated with the gel, or may contain a tooth-whitener, and may be coated onto a non-porous, porous or micro-porous backing. Wounds treated with dressings in accordance with embodiment of the invention will tend to heal without the formation of a typical hard scab. The dressing may also be covered with a protective coating such as a cyanoacrylic liquid or spray, or may be attached to a backing such as an adhesive bandage to protect the wound from an excessively fluids environment and from mechanical stresses.

  • Patent number: 5941409
    Abstract: A teapot cup is shown for brewing and drinking a heated beverage such as tea. The teapot cup includes a cup body having a cup base and a cup wall surrounding the base to define a liquid chamber. A drinking spout is secured to the cup wall and defines a liquid passage extending between a screened entry passage secured to the cup body adjacent the cup base and a mouthpiece positioned adjacent a top edge of the cup wall. The drinking spout includes a lip flair secured to the mouthpiece. Openings in the screened entry passage are dimensioned to permit flow of liquid into the liquid passage, but to restrict passage of particles having a length of a longest axis greater than one millimeter, such as tea leaves. A cup handle is secured to the cup wall and is positioned within a handle range that is between thirty-five degrees and one-hundred and thirty-five degrees from the drinking spout.
