The present invention generally relates to a portable toilet, and more specifically to a disposable portable toilet system for safely retaining, neutralizing, and disposing human waste. Accordingly, the present specification makes specific reference thereto. However, it is to be appreciated that aspects of the present invention are also equally amenable to other like applications, devices, and methods of manufacture.
Many parents avoid taking their children in the car and out for daily errands for fear that they will need to expose their children to an unsanitary public restroom. Road trips can be especially stressful because it is inevitable that different family members will need to use a public restroom throughout the trip. Often even locating a restroom while on a long car ride can be difficult. For individuals that suffer from incontinence, it can also be stressful to be out of the house without a private and accessible bathroom. Campers must make special provisions for restroom access when traveling in remote location. There are many situations where having a portable and hygienic bathroom option in a vehicle would be beneficial.
A portable or mobile toilet is any type of toilet that can be moved around. Most types do not require any pre-existing services or infrastructure, such as sewerage, but are completely self-contained. Larger portable toilets are not very portable, requiring machinery to relocate which is not practical for a traveler. A bucket toilet or camping toilet is a basic form of a dry toilet whereby a bucket or pail is used to collect excreta. Usually, feces and urine are collected together in the same bucket, leading to odor and sanitary issues. The bucket toilet may be situated used in a dwelling, a tent, a vehicle, or even out in the open. The bucket toilet may employ a liner, so that waste may be removed with each use or when the toilet is filled.
Accordingly, there is a great need for a convenient alternative to pulling over frequently to locate a clean restroom. There is also a need for a way for a system to afford peace of mind to individuals with incontinence that a hygienic and private bathroom option is always accessible to them when needed. Similarly, there is a need for a portable toilet system that improves road trips and day to day car rides by offering a clean bathroom in the privacy of one's own vehicle for use by children and adults. There is also a need for a way to eliminate the need for outdoor enthusiasts and campers to make a special provision for using the restroom in remote areas. Further, there is a need for a portable lavatory system for any vehicle that effectively receives human waste, dries it, sanitizes it, and deodorizes it for disposal.
In this manner, the improved disposable portable toilet system of the present invention accomplishes all of the forgoing objectives, thereby providing an easy solution for carrying out bodily functions on the go. A primary feature of the present invention is a hygienic and private bathroom option that is always accessible when needed The present invention provides a clean toilet solution in the privacy of one's own vehicle Finally, the improved disposable portable toilet system of the present invention is capable of providing a portable lavatory system that effectively receives human waste, dries it, sanitizes it, and deodorizes it for disposal.
The following presents a simplified summary in order to provide a basic understanding of some aspects of the disclosed innovation. This summary is not an extensive overview, and it is not intended to identify key/critical elements or to delineate the scope thereof. Its sole purpose is to present some concepts in a simplified form as a prelude to the more detailed description that is presented later.
The subject matter disclosed and claimed herein, in one embodiment thereof, comprises a disposable portable toilet system. The disposable portable toilet system is constructed with a combination of disposable and reusable components. The disposable components are biodegradable in construction. The system collects and converts human excreta into inert non-biohazard material for easy disposal.
The disposable portable toilet system comprises a waste collection component, a chemical component, and a seat component. The waste collection component is constructed from biodegradable materials. The waste collection component comprises an outer shell, an inner liner, and a waste collection area. The outer shell is configured in a generally rectangular shape that is open at the top. The inner liner forms a water-proof layer that coats an inside of the outer shell and defines the waste collection area. The waste collection component further comprises a hinged lid that is attachable to the outer shell at one end. The hinged lid is configured to act as a privacy shield when open and covers the open top of the outer shell when closed effectively sealing the waste collection container.

The hinged lid 130 may comprise a sealing element or gasket (not shown) to engage the top rim 122 of the outer shell 112 to form a water-tight seal. The front lip 134 engages the front end wall 116 and may be secured with a fastening mechanism or adhesive.
The chemical component 140 is positional within the waste collection area 126 of the waste collection component 110 prior to use. The chemical component 130 is formulated to sanitize, solidify, and absorb human excreta deposited within the waste collection area 126. The chemical component 140 comprises a sanitizing agent, a solidifying agent, and an absorbent. A mixture of the sanitizing agent, solidifying agent, and absorbent is retained in a water soluble pouch 142.
The sanitizing agent is typically a salt based sanitizing agent. One preferred composition of the sanitizing agent is a metal oxide mixture of sodium, potassium, calcium, aluminum, iron, and silicon elements. One preferred formulation of the sanitizing agent is 53.04% sodium, 23.2% potassium, 11.8% calcium, 6.64% aluminum, 3.81% iron, and 2.51% silicon 2.51%. The sanitizing agent is formulated to sanitize the excreta.
The solidifying agent is a mixture of calcium, silica, alumina, and iron. One preferred formulation of the solidifying agent is a Portland cement comprising a mixture of approximately 67.54% tricalcium silicate (Ca3SiO5), 28.13% dicalcium silicate (Ca2SiO4), 3.11% tricalcium aluminate (Ca3Al2O5), and 1.2% calcium aluminoferrite (Ca4AlnFe2-nO7). The calcium is typically derived from limestone, marl, or chalk, while silica, alumina and iron come from the sands, clays and iron ore sources. The solidifying agent is formulated to remove water from and solidify liquid excreta.
The absorbent is typically an organic biodegradable litter derived from plant material. Biodegradable litters are typically made from various plant resources, including pine wood pellets, recycled newspaper, clumping sawdust, Brazilian cassava, corn, wheat, walnuts, barley, soy pulp and dried orange peel. The biodegradable litter may be a cat litter. The absorbent is formulated to remove water from and solidify liquid excreta.
In one embodiment, the chemical component is formulated with a ratio of one part of the sanitizing agent, one part of the solidifying agent, and four parts of the absorbent. By weight, the chemical component may be approximately 28.35 grams (salt based sanitizing agent, approximately 28.35 grams (solidifying agent), and approximately 113.4 grams (absorbent). In one example, the chemical component may be approximately six ounces and formulated as follows: one ounce of Smelleze® Blood and waste sanitizer absorbent (salt based sanitizing agent), one ounce of Portland Lyme (solidifying agent), and four ounces of organic Kitty litter. This is not meant as a limitation as a ratio of the formulation components may vary depending on the needs of the user.
The water soluble pouch 142 is positional within the waste collection area 126 of the waste collection component 110. The water soluble pouch 142 is constructed to release the retained chemical component 140 when the waste collection component 110 is shaken. Once released, the chemical component 140 interacts with the human excreta to convert it into safe non-biohazard material for traditional disposal.
