  • Odors are gaseous molecules that escape from the bulk liquid in the toilet bowl. It is known for example, that an immiscible liquid, especially a scented oil, can limit the odors emanating from the toilet bowl, as the molecules of the odor-causing gas need to pass from the aqueous medium into the oily medium and then to escape from the oily medium. Unfortunately, this solution becomes impractical once the toilet is flushed. To achieve an acceptable level of cleaning the toilet bowl, it is advantageous to create a turbulent flow of water during the flushing process. This turbulence increases the energy available to allow the odors to escape.
  • the germs that the inventive concept seeks to limit are not gaseous, or, in fact, they are not liquid. They are particles that are suspended in the liquid. They escape from the liquid as an aerosol, not as a gas.
  • An aerosol is a colloidal suspension of liquid particles dispersed in air. Aerosols are formed by the same turbulence that enhances the emission of odors. In general, the effects of the turbulent liquid flow occur in the vicinity directly above the water surface.
  • Embodiments of the invention are described herein with reference to illustrations that are schematic illustrations of idealized embodiments (and intermediate structures) of the invention. As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances, are to be expected. Thus, embodiments of the invention should not be construed as limited to the particular shapes of regions illustrated herein but are to include deviations in shapes that result, for example, from manufacturing.
  • the invention comprises a toilet bowl covering system comprising four elements:
  • a Rigid Toilet Bowl Cover Device that can be flat, lipped, or indented to fit the bowl and can be made of a variety of materials from disposable cardboard or plastic to durable plastics, rubber, glass or wood.
  • this element may have a specialized dispensing unit to shield and store the unused rigid toilet bowl covers until they are needed on an individual use basis by the end user.
  • the Rigid Toilet Bowl Cover Device Protector can be a sleeve or a skirted version and can be made of durable cloth, disposable cloth, plastic, paper or any combination of these elements, and can also treated with antimicrobial agents for maximum protection.
  • this element may have a specialized dispensing unit to shield and store the unused Rigid Toilet Bowl Cover Device Protectors until they are needed on an individual use basis by the end user.
  • Alternative versions of the Rigid Toilet Bowl Cover Device Protector can be a bouffant cap style or a flat sheet with optional adhesive tabs or dots that allow the user to seat the protector where it is of most benefit on the toilet bowl itself. All versions can be used seated on the toilet bowl or around the existing toilet seat on or seated on the Rigid Toilet Bowl Covering Device.
  • the Storage and Cleaning Vessel for the Rigid Toilet Bowl Cover Device can sit on the floor, hang on the wall with the ability to be easily removed as a part of a hanger/holder system, and can have a drainage element that opens and closes.
  • the Storage and Cleaning Vessel for the Rigid Toilet Bowl Cover Device can be made of plastic, glass, composite, rubber or any sufficiently durable and rigid material.
  • the drainage element can be made of plastic, glass or rubber and can be as simple as a plug or sluice gate or as complex as a screw top or tap.
  • Blocking Tabs for "seeing eye” for automatic flush toilets are the final element and can be made of paper, plastic, cloth, metal or wood. Because many toilets in public spaces are automatic flush models, in order to properly seat the protectors prior to the toilet flushing, Blocking Tabs used to block the "seeing eye” sensors must be included, along with directions on how to use the full protection system described in this document as applicable to the element in question.
  • This element may have a separate, proprietary specialized dispensing unit to shield and store the unused "seeing eye” Blocking Tabs until they are needed on an individual use basis by the end user.
  • the proprietary dispensing unit can be made of cardboard, plastic, metal, fabric, glass, wood, rubber or any sufficiently rigid and durable material. This element's proprietary specialized dispensing unit may also be part of the dispensing unit for the protective seat covers. Blocking Tabs are removed from the seeing eye and disposed of following a single use or can be of a durable nature and used over and over.
  • a Travel/Disposable Toilet Bowl Covering Device embodiment consists of several elements.
  • the Travel/Disposable Toilet Bowl Covering Device itself is a folded, disposable iteration of the seat/rigid toilet bowl cover protector that can be distributed in bulk and dispensed for single use in a proprietary stationary dispensing device, packaged in disposable, portable single or multi-protective cover packs, or in smaller bulk quantities that can be placed in a proprietary portable reusable container.
  • the disposable, protective covers can be made of cloth, paper, plastic, rubber, or cardboard.
  • the proprietary device for dispensing the disposable, protective covers can be made of cardboard, paper, plastic, rubber, metal, glass or wood.
  • the proprietary portable reusable container for Travel/Disposable Toilet Bowl Covering Device can be made of cardboard, paper, plastic, fabric, rubber, metal, glass or wood.
  • Blocking Tabs for the "seeing eyes" on some toilets will be included with all seat protectors dispensed in single or multi-use packs. They may also be distributed as a single product.
  • a treated, disposable wipe in a new kind of disposable package with a tearaway tab can be included in the package of seat protector(s), as a standalone produce or dispensed in proprietary dispensers.
  • the disposable package with tear-away tab can also include a "popup handle" formed by pulling up semi-rigid parts of material to form a handle for additional protection and dexterity.
  • the proprietary portable reusable container may have provision for storing the blocking tabs and disposable wipes or each item may have their own proprietary, portable reusable container.
  • the Blocking Tabs' and disposable wipes' proprietary portable reusable containers can be made of cardboard, paper, plastic, fabric, rubber, metal, glass or wood.
  • the Aerosol-Spread-Limiting Toilet Bowl Seat and Lid is unique in that it has ridges that extend beyond the toilet bowl, a toilet seat that "nests" inside the lid, and optional ridge and sealant (sealant strip materials) that limit the exposure of both the toilet seat's seating surface and the environment outside of the toilet to the aerosols generated by flushing.
  • This device will not seal off the toilet bowl but merely limit the spread of flush-generated aerosols. Further, this device allows for continued normal use of the toilet bowl.
  • the sides of the lid can optionally be made of a collapsible material to allow the lid to accordion for more comfortable seating while continuing to limit the spread of aerosols while extended.
  • the device can be made of plastic, wood, glass, rubber, composite, fabric or any sufficiently strong material to support a human and can be made to fit a variety of toilet bowl sizes.
  • the sealant strips can be made of any material that allows it to provide a seal including rubber, foam, paper, or plastic.
  • the Aerosol-Spread-Limiting Toilet Bowl Seat has a mechanism that allows it to be easily released from the toilet bowl for submersive cleaning in a proprietary Storage and Cleaning Vessel made for this seat.
  • the Storage and Cleaning Vessel for the aerosol-spread-limiting toilet seat device can sit on the floor, hang on the wall with the ability to be easily removed as a part of a hanger/holder system, and can have a drainage element that opens and closes.
  • the vessel can be made of plastic, glass or rubber.
  • the drainage element can be made of plastic, glass or rubber and can be as simple as a plug or sluice gate or as complex as a screw top or tap.
  • the benefit to this system is that it limits the spread of chemicals, organisms, waste, and other materials that are aerosolized when a toilet is flushed, thus limiting the spread of those materials in the surrounding environment, including into the air, on the toilet seat, lid, toilet stool, and other bathroom fixtures, other items in the area of the toilet, including towels and toothbrushes, the individual flushing the toilet, their garments and any items they may have brought near the toilet (such as IV stands in a medical environment), and as well as other nearby (toilet aerosols can travel up to eight feet) areas which are often contaminated by aerosolize toilet mists.
