  • Patent number: 5172652
    Abstract: A vessel for containing pet waste and litter material is formed of recycled paper for absorbing liquids and preventing odor. The vessel preferably has essentially vertical side members, having upper edges, and an essentially horizontal bottom member, interconnected in a sealing relationship. The upper edges of the side members preferably tilt out from the interior of the vessel. A horizontal lip preferably projects from the upper edges of the side members, outside the vessel. A cover member is optionally provided, which is joined to the side member upper edges to cover and seal the vessel. The cover member preferably has a middle area, defined by perforations or surface scoring, which can be torn out along the perforations or surface scoring to expose the interior of the vessel so that the remaining portion of the cover member forms an inwardly projecting, horizontal lip for retaining the litter material. The vessel may be impregnated with an antibacterial agent, a drying agent and a scent.

  • Patent number: 4464293
    Abstract: A liquid composition formulated especially for use in wiping down non-disposable surfaces in a dental operatory is disclosed. The composition consists essentially of between 50 and 91% by volume of isopropyl alcohol, between 0.5 and 1.5% by volume of a skin emollient, between 0.19 and 2.5% by volume of a scent, between 0.3 and 1.5% by volume of a cationic detergent, between 0.5 and 8% by volume of an nonionic detergent and the remainder up to 100% by volume of water. The alcohol acts as a disinfectant, the skin emollient prevents drying of the skin, the scent masks the smell of the alcohol, the two detergents act as cleaning agents and the water serves as a carrier to cut the proportions of the various ingredients that make up the composition.
