Screens have been used in urinals in order to protect the urinals against flushing extraneous items and materials that could clog the toilet. These The urinal screens can be used for deodorizing, disinfectant, protecting backsplash, protecting blockages protecting against stains, and generally improving the tidiness of the urinal.
A urinal screen has conventionally not allowed solids to pass through the screen.
The inventor recognized that many advantages can be obtained by use of a screen in a conventional, non-urinal, toilet. However, conventional urinal screens cannot be used with a regular toilet which often receives solid waste.
The present application describes a toilet screen for use in a conventional toilet that has a central hole. The screen includes a hole in the center to allow passage of solid waste. The screen also includes toilet cleaning features, including tabs at the bottom for cleaning the toilet, and other features that enable the screen to carry out functions including deodorization, cleaning of the toilet bowl, and anti-splash.
In the Drawings:
The present application describes a screen for use in a toilet. In an embodiment, the screen is made of vinyl plastic. A deodorizing additive can be included in the screen, which may be impregnated with or encapsulated with the deodorant or may be container areas for the deodorant material.
The embodiments are shown in the figures.
The screen 150 is shown in this embodiment at the bottom of the toilet. The screen can be formed of plastic. In other embodiments, the screen can be formed of other materials, including biodegradable materials, and as described herein, of materials that dissolve. In one embodiment, the screen can be formed of a paperlike material or other biodegradable material.
In a first embodiment, shown in
According to another embodiment, the screen 400, is made of a dissolvable material, for example a material that dissolves after it is submerged between 4 and 96 hours in water, although the dissolving time can be any amount of time. This material can stick to the edges of the bowl, for example it can stick to the bottom of the bowl once it reaches the bottom of the bowl by sinking in the bowl. At that point, the material sticks to the bottom of the bowl, but dissolves in due course, leaving no residue on the bowl. This embodiment addresses the concern that otherwise the screen could be flushed down the toilet, because it sticks to the edges of the bowl and is dissolvable so even if it flushes down the toilet it will dissolve. However, by sticking to the edges of the bowl, this embodiment can put a covering over the bowl surfaces that keeps those surfaces clean, and eventually dissolves.
The dissolvable material, in an embodiment, can have an impregnated cleaning material or impregnated scent reducing material.
In another embodiment, shown in
In an embodiment, the chemical holder such as 202 is radially symmetrical. There can be multiple chemical holders such as 202, 205, or the chemical holder and/or its material can be formed in a doughnut shape around a diameter of the screen.
The screen 400 sits on the top surface 405 of the water normally, that is when the toilet is not flushing. In an embodiment, the screen 400 also includes tabs like 402 similar to those in the embodiment of
The previous description of the disclosed exemplary embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these exemplary embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
