  • Patent number: 10350322
    Abstract: An automatic dispensing device for volatile fluid operable to apply one or more agent to a local environment for more than 14 days. Preferred devices dispense a first agent for air freshening, and may optionally dispense a second agent, such as a drain cleaner. A workable drain cleaner is structured to permit a slow release of drain cleaning agent. A dispensing device may nonexclusively operate by evaporation of volatile fluid from a polymer or rubber-like carrier material that is infused with the volatile fluid; gravity-induced drip from a bulk supply of volatile fluid through a small orifice onto an emanator; osmotic transfer of volatile fluid from a bulk supply; gas-pump drive of volatile fluid at controlled pressure; or diffusion of volatile fluid through a wall of a container of bulk volatile fluid; and combinations thereof.

  • Patent number: 8485216
    Abstract: In a urine cartridge or wastewater trap, equalized pressures and increased flow rate between its inlet and outlet compartments increases the life of the cartridge. The pressure equalizing is effected by placement of a separator between the two compartments to provide them with substantially equal volumes. The increased flow rate is created by a uniquely configured baffle positioned adjacent a pan at the bottom of the cartridge. The baffle configuration is shaped to provide a constriction that increases the flow velocity of the urine so that the fluid flow effects a channel along the bottom pan and through any solids deposited on the bottom pan. A diverter may be placed above the centrally located entry to the inlet compartment to create a circuitous path for preventing a disturbing impingement of the urine onto the sealant contained in the inlet compartment.

  • Patent number: 5165119
    Abstract: The chemical setting receptacle comprises a receptacle body loading chemical and a lid covering the top opening of the receptacle body, wherein the lid is formed by connecting more than one vertical plate and a passage connected to a chemical loading section of the receptacle body is installed between the vertical plates. Urine and water hitting the ridge of the vertical plate separate and fall into the chemical loading section and also, urine and water entering the passage hit the side of the vertical plate and fall into the chemical loading section. Therefore, urine and water do not splash outward. The receptacle body and lid are made of decomposable plastic material containing an additive having a decomposition by microorganisms and sunlight characteristic. After the receptacle is used, the additive is naturally decomposed in a short time by activity of microorganisms and irradiation of sunlight, the plastic material collapses into a granular resin, and the receptacle loses its original form.

  • Patent number: 4777670
    Abstract: A dispenser for dispensing a dissolvable product into a toilet bowl. The structure of the dispenser properly meters and times the flow of water therethrough to increase operational efficiency. The dispenser includes a substantially sealed container enclosing the product and having an entrance hole and an exit hole. Water flow interruptions are positioned to interrupt the flow of flush water and to channel the water to the entrance. A sufficient change of water is guaranteed by the deflectors while excess water is limited by the size of the entrance. A deflector is positioned to deflect water away from the product, and instead to cause the water to rise gently in the containers. The size of the exit hole ensures that water remains in the container after flushing has stopped, so that the dissolved product is efficiently infused into the water standing in the toilet bowl as the water level in the container recedes.
