Portable Disposable Toilet

The present invention is directed to a portable toilet that includes one or more disposable components. The portable toilet has the advantage of being easier to clean, and easier and more convenient to transport.

BACKGROUND OF THE INVENTION

Portable toilets are known in the art. Non-limiting examples of such prior art portable toilets are disclosed in U.S. D624,663; U.S. D545,451; U.S. D519,645; U.S. D452,901; U.S. Pat. No. 6,668,392; U.S. Pat. No. 6,507,958; U.S. Pat. No. 6,427,256; U.S. Pat. No. 5,448,785; U.S. Pat. No. 4,744,111; U.S. Pat. No. 4,380,836; US 2007/0174955; US 2003/0208838; WO 2009/123655; and DE 10342371, all of which are fully incorporated herein by reference.

Prior art portable toilets are commonly modular units that are formed of plastic material. The portable toilets are typically shipped assembled. After used, the complete interior is cleaned and flushed out for subsequent use. Although prior art portable toilets have advantageously solved sanitary problems in locations that have insufficient, few or no bathroom facilities, these prior art portable toilets have several disadvantages.

One disadvantage of prior art portable toilet is the time and difficulty of thoroughly cleaning the portable toilet after use. The interior cavity of the portable toilet must be fully cleaned and sanitized after use. The small interior cavity makes it difficult to access the complete interior cavity. As such, the cleaning of the portable toilet is very time consuming and labor intensive. Also, the proper and constant cleaning of the interior components of the portable toilet is difficult to maintain.

Another disadvantage of prior art portable toilets is that the assembled portable toilets are bulky, thus only a few portable toilets can be transported at a time by a standard truck. Larger transport trucks are required to transports larger numbers of the portable toilets. The size, weight and bulk of the portable toilets require multiple individuals to move the portable toilets on and off of a transport vehicle. As such, the shipping, unloading and loading of the portable toilets are very labor intensive and typically require multiple individuals.

Another disadvantage associated with portable toilets is the difficulty associated with branding a portable toilet. Many public events (e.g., fairs, carnivals, outdoor craft shows, outdoor festivals, outdoor cooking events, etc.) that draw substantial numbers of people to a location that typically do not have sanitary facilities for large groups of people (e.g., parks, parking lots, street events, etc.) are sponsored by one or more companies or organizations. These events also typically require the use of portable toilets to accommodate the sanitary requirements of large groups of people at the event. Many sponsors seek branding of items at the event to promote the company or organization. The inclusion of advertising on the portable toilets generally is difficult or expensive. Custom painting or forming the portable toilet to include a brand name or symbol on the portable toilet is expensive and the portable toilet must forever be used with such brand. Banners or stickers can be applied to the portable toilet; however, such banners can be unsanitary or easily removed, and stickers can be difficult to remove thus defacing the portable toilet.

In view of the current state of the art of portable toilets, there is a need for an improved portable toilet that is easy to clean, transport, and which can be branded.

SUMMARY OF THE INVENTION

The present invention is directed to a portable toilet that includes one or more disposable components. The portable toilet is designed to be easy to clean, and easier and more convenient to transport than prior art portable toilets. In one non-limiting embodiment of the invention, the portable toilet is formed of disposable and reusable components. In one non-limiting arrangement, all or a portion of the side wall of the portable toilet is formed of one or more disposable components (e.g., paper board, cardboard, fiber board, press board, etc.). In one non-limiting design, all or a portion of the side wall of the portable toilet is formed of a paper board, cardboard material, press board, and/or fiberboard material. As can be appreciated, paper board, cardboard material, press board, and/or fiberboard material can include materials in addition to or other than cellulose materials (e.g., plastic material, starch, adhesives, composite materials, etc.); however, this is not required. The paper board, cardboard material, press board, and/or fiberboard material is designed to be disposable after use of the portable toilet. The paper board, cardboard material, press board and/or fiberboard material is generally formed or includes recycled materials; however, this is not required. The color and thickness of the paper board, cardboard material, press board and/or fiberboard material is non-limiting. One or more layers of paper board, cardboard material, press board, and/or fiberboard material can be used to form the side wall of the portable toilet. Generally, the total thickness of the one or more layers of paper board, cardboard material, press board and/or fiberboard material used to form the side wall of the portable toilet is least about 0.125 inches; however, thinner thicknesses can be used. Generally, the total thickness of the one or more layers of paper board, cardboard material, press board and/or fiberboard material used to form the side wall of the portable toilet is up to about 6 inches; however, greater thicknesses can be used. In one non-limiting configuration, the total thickness of the one or more layers of paper board, cardboard material, press board and/or fiberboard material used to form the side wall of the portable toilet is about 0.25-5 inches, typically the total thickness of the one or more layers of paper board, cardboard material, press board and/or fiberboard material used to form the side wall of the portable toilet is about 0.25-4 inches, more typically the total thickness of the one or more layers of paper board, cardboard material, press board and/or fiberboard material used to form the side wall of the portable toilet is about 0.5-4 inches, even more typically the total thickness of the one or more layers of paper board, cardboard material, press board and/or fiberboard material used to form the side wall of the portable toilet is about 0.5-3 inches, and still even more typically the total thickness of the one or more layers of paper board, cardboard material, press board and/or fiberboard material used to form the side wall of the portable toilet is about 0.5-2 inches. The use of a disposable paper board, cardboard material, press board and/or fiberboard material for all or a portion of the side wall of the portable toilet can result in the total weight of the portable toilet to be lighter than standard prior art portable toilets. Generally the portable toilet of the present invention is about 10%-50% lighter than prior art portable toilets of the same size, shape and configuration. In another and/or alternative non-limiting embodiment of the invention, the disposable material forms about 10%-100% of the side wall of the portable toilet. The disposable material used on the side wall of the portable toilet enables such material to be recycled or disposed of after use of the portable toilet, thus this portion of the portable toilet does not require cleaning after use. As such, the portable toilet of the present invention has less area to be cleaned after use, thus reducing the time and manpower required to clean the portable toilet of the present invention. In one non-limiting design, the disposable material forms about 25%-100% of the side wall of the portable toilet, typically the disposable material forms about 40%-100% of the side wall of the portable toilet, more typically the disposable material forms at least a majority of the side wall of the portable toilet, still more typically the disposable material forms about 60%-100% of the side wall of the portable toilet, and even more typically the disposable material forms about 75%-100% of the side wall of the portable toilet.

In one non-limiting aspect of the present invention, the portable toilet of the present invention includes a disposable side wall and modular non-disposable top and/or bottom sections. The disposable side wall is generally formed of a disposable material such as, but not limited to paper board, cardboard, corrugated paper board, fiber board, press board, and the like. Generally the disposable material is completely or partially formed of a cellulose material; however, this is not required. As can be appreciated, all or a portion of the side wall of the portable toilet can be formed of a disposable paper product. The top and/or bottom sections of the portable toilet are fully or partially formed of materials that are reusable and can generally be easily cleaned. Non-limiting examples of materials that are reusable and can generally be easily cleaned include plastic, composite materials, fiberglass, carbon fiber material, metal, and the like. In one non-limiting embodiment of the invention, the top section of the portable toilet is formed of a reusable material. In one non-limiting design, the top section is designed to facilitate in securing to the side wall of the portable toilet and maintain the shape of the side wall of the portable toilet; however, this is not required. In another and/or alternative non-limiting design, the top section can be designed to be easily connected to and/or removed from the side wall of the portable toilet so as to facilitate in easy assembly and/or disassembly of the portable toilet. In still another and/or alternative non-limiting design, the roof or ceiling that is formed by the top section can be formed of a reusable or a disposable material. In one non-limiting configuration, the roof or ceiling that is formed by the top section can be formed of a reusable material. In such a configuration, the top section can be a single piece of material (e.g., molded plastic material, etc.); however, this is not required. In another non-limiting configuration, the roof or ceiling that is formed by the top section can be formed of a disposable material. In such a configuration, the ceiling or roof can be formed of a cellulose material and/or cellulose containing material (e.g., paper board, cardboard, corrugated paper board, fiber board, press board, wood, etc.). The disposable material can be designed to be easily inserted and/or removed from the reusable portion of the top section for easy assembly and/or disassembly of the portable toilet; however, this is not required. The inclusion of disposable materials on the top section can be used to lighten the top section, reduce the time necessary to the clean the top section, and/or increase the ease to clean the top section; however, this is not required. The material used to form the disposable ceiling or roof can be the same or similar material and/or have the same or similar thickness as the material used to form the disposable side wall of the portable toilet; however, this is not required. In another non-limiting configuration, the top surface of the roof or ceiling that is formed by the top section can be formed into certain shapes that correspond to the theme of the portable toilet; however, this is not required. For example, if the portable toilet was shaped similarly to a can and included advertising that was associated with the look of a can (e.g., Coke can, Sprite can, Dr. Pepper can, Pepsi Can, Mountain Dew can. etc.), the top surface of the ceiling or roof can be designed to look similar to the top of such a can (e.g., include structures that look similar to the opening tab of the can, etc.); however, this is not required. In still yet another and/or alternative non-limiting design, the bottom section can be designed to be easily connected to and/or removed from the side wall of the portable toilet so as to facilitate in easy assembly and/or disassembly of the portable toilet. In another and/or alternative non-limiting design, the floor that is formed by the bottom section can be formed of a reusable or a disposable material. In one non-limiting configuration, the floor of the portable toilet that is formed by the bottom section can be formed of a reusable material. In such a configuration, the bottom section can be a single piece of material (e.g., molded plastic material, etc.); however, this is not required. In another non-limiting configuration, the floor that is formed by the bottom section can be formed of a disposable material. In such a configuration, the floor can be formed of a cellulose material and/or cellulose containing material (e.g., paper board, cardboard, corrugated paper board, fiber board, press board, wood, etc.). The disposable material can be designed to be easily inserted and/or removed from the reusable portion of the bottom section for easy assembly and/or disassembly of the portable toilet; however, this is not required. The inclusion of disposable materials on the bottom section can be used to lighten the bottom section, reduce the time necessary to the clear the bottom section, and/or increase the ease to clean the bottom section; however, this is not required. The material used to form the disposable floor can be the same or similar material and/or have the same of similar thickness as the material used to form the disposable side wall of the portable toilet; however, this is not required.

In another and/or alternative non-limiting aspect of the invention, the portable toilet includes a door system. The configuration of the door system is non-limiting. For purposes of the present invention, the door system is separate from the side wall of the portable toilet. In one non-limiting embodiment of the invention, the door system is formed of reusable materials. In another and/or alternative non-limiting embodiment of the invention, the door system includes or is fully formed of disposable materials. In still another and/or alternative non-limiting embodiment of the invention, the door system is connected to the top and/or bottom section of the portable toilet; however, this is not required. In yet another and/or alternative non-limiting embodiment of the invention, the door system includes a locking arrangement to enable a user in the portable toilet to lock and unlock the one or more doors on the door system; however, this is not required. In still yet another and/or alternative non-limiting embodiment of the invention, the door system includes a single door. In another and/or alternative non-limiting embodiment of the invention, the door system includes two doors. In still another and/or alternative non-limiting embodiment of the invention, one or more doors on the door system include a handle and/or grasping region to facilitate in the opening and/or closing of the one or more doors; however, this is not required. In yet another and/or alternative non-limiting embodiment of the invention, one or more doors on the door system are pivotally connected to a frame of the door system; however, this is not required. In still yet another and/or alternative non-limiting embodiment of the invention, the door system is connectable to the side wall of the portable toilet; however, this is not required.

In still another and/or alternative non-limiting aspect of the invention, the disposable side wall of the portable toilet includes one or more groove or slots that enable the side wall to be bent to the desired configuration during the assembly of the portable toilet. One of the importable advantages of the portable toilet of the present invention is the modular configuration of the portable toilet. Generally all or a portion of the bottom and top of the portable toilet is formed of a reusable material such as plastic. These pieces are generally shipped to a location and the portable toilet is assembled at a particular location which is generally where the portable toilet is to be used; however, this is not required. Likewise, the door system is generally shipped to a location and the portable toilet is assembled at a particular location which is generally where the portable toilet is to be used; however, this is not required. The door system is generally formed of a reusable material such as plastic; however, this is not required. Furthermore, the side wall of the portable toilet is generally shipped to a location and the portable toilet is assembled at a particular location which is generally where the portable toilet is to be used; however, this is not required. When the side wall is in the form of paper board, cardboard, corrugated paper board, fiber board, press board and the like, the side wall is generally shipped in the form of a flat or generally flat sheet for easy packaging, spacing saving, storage and transport. The modular design of the portable toilet results in easier packaging, space savings, storage and transport of the components of the portable toilet as compared to fully assembled prior art portable toilets. Once the side wall is delivered to a desired location, the flat side wall must be bent in certain regions so that the side wall can be fitted to the top section, bottom section and/or door system of the portable toilet during assembly of the portable toilet. In one non-limiting configuration, the side wall is formed of one or more sections, wherein at least one of the sections includes a groove or slot that facilitates in the bending of the side wall to conform with the shape of at least a portion of the outer surface of the portable toilet. In another non-limiting configuration, the side wall is formed of one piece and the side wall includes a plurality of grooves or slots to facilitate in the bending of the side wall to conform to the shape of the outer side wall of the portable toilet. In this non-limiting configuration, the side wall generally includes 3-10 grooves or slots so that the one piece side wall can be bent at 3-10 locations, typically includes 3-8 grooves or slots so that the one piece side wall can be bent at 3-8 locations, more typically includes 3-6 grooves or slots so that the one piece side wall can be bent at 3-7 locations. As can be appreciated, the side wall can include more than 10 grooves or slots.

In yet another and/or alternative non-limiting aspect of the invention, the disposable side wall can include printed advertising, designs and/or literature on the inner and/or outer surface of the disposable side wall; however, this is not required. In one non-limiting embodiment of the invention, the outside surface of the side wall can include sponsorship information regarding event sponsors, companies sponsoring the portable toilets, etc. In another and/or additional non-limiting embodiment of the invention, the outside surface of the side wall can include printed designs and/or information, etc. to make the outside of the portable toilet look similar to a product (e.g., beverage can [e.g., Red Bull can, Coke can, Pepsi can, Miller can, Budweiser can, etc.], beverage bottle [Coke bottle, Pierre bottle, etc.], beverage container [e.g., Gatorade, 5-Hour Energy bottle, etc.], oil can [Mobil Oil can, Pennzoil can, etc.], non-beverage container [e.g., Comet can, Turtle Wax can, etc.], sponsorship information regarding event sponsors, companies sponsoring the portable toilets, etc. In still another and/or additional non-limiting embodiment of the invention, the inside surface of the side wall can include printed designs and/or information (e.g., sponsorship information, information on use of the portable toilet, safety information, emergency information, etc.), etc.; however, this is not required.

In still yet another and/or alternative non-limiting aspect of the invention, the top and/or bottom section of the portable toilet can include a configuration that facilitates in creating an overall look of the portable toilet regarding a product configuration. For example, when the outside side wall of the portable toilet includes printing to make the portable toilet look like a product (e.g., Coke can, etc.), the top and/or bottom sections of the portable toilet can also be designed to include one or more features of the product (e.g., top section includes features that look like the can tab for a Coke can, top section includes a rim that looks like the top rim of a Coke can, top section includes a curved profile that looks like the curved profile of the top of a Coke can, bottom section includes a curved profile that looks like the curved profile of the bottom of a Coke can, etc.); however, this is not required.

In another and/or alternative non-limiting aspect of the invention, the top section, bottom section and/or side wall of the portable toilet can include one or more vents or vent openings; however, this is not required.

In still another and/or alternative non-limiting aspect of the invention, the interior of the portable toilet can include one or more features (e.g., sink, toilet paper dispenser, faucet, urinal, toilet, mirror, shelf, handle, toilet seat, toilet lid, refuse receptacle, fan, light, pump, etc.).

In yet another and/or alternative non-limiting aspect of the invention, the top and bottom sections can be designed to be stacked together for easy transport; however, this is not required. In one non-limiting embodiment, sets of stacked top and bottom sections can be stacked together for easy transport; however, this is not required.

In still yet another and/or alternative non-limiting aspect of the invention, the toilet system that is used on the interior of the portable toilet can be foldable for compact shipping; however, this is not required. In one non-limiting embodiment, the toilet system is foldable such that can be positioned between two stacked top and bottom sections for easy transport and storage; however, this is not required.

In another and/or alternative non-limiting aspect of the invention, the side wall includes one or more mounting slots that are used to secure the toilet system to the side wall of the portable toilet; however, this is not required.

In still another and/or alternative non-limiting aspect of the invention, a removable disposable waste pouch is positioned in the toilet of the toilet system to collect waste deposited in the toilet; however, this is not required. The removable disposable waste pouch can be substituted for a standard waste tank that is commonly used in a portable toilet. The use of the removable disposable waste pouch is designed to save space, reduce the weight of the portable toilet, make the transport of the portable toilet components simpler, make the disposal of waste simpler, and/or make the assembly of the portable toilet simpler; however, this is not required.

In use, the top section, bottom section, door assembly, and internal components of the portable toilet (e.g., urinal, toilet structure, toilet seat, etc.) are shipped to an event location in unassembled form. Since these components are unassembled, more of these components can be shipped in the same space than if the portable toilet had been preassembled. The side wall can also be shipped with the reusable components of the portable toilet or shipped separately. Generally the side wall is not pre-bent, but may be pre-creased so that the side wall, during assembly of the portable toilet, can be more easily formed into shape; however, this is not required. The unassembled portable toilet takes up less space than traditional preassembled toilets; thus the portable toilets of the present invention are easier to store, and takes up less space during storage and transport. The portable toilets of the present invention are also generally lighter than traditional portable toilets. The portable toilets of the present invention are to be designed for easy assembly at an event site, and can be easily disassembled after the event is completed. The side wall is designed to be disposed of after the portable toilet is disassembled, thus reducing cleanup time of the other reusable components of the portable toilet. The reusable components are generally formed of durable materials (e.g., plastic materials, etc.) that can be easily cleaned and then reshipped to another event and/or stored for later use. The disposable side wall is generally made of recyclable material so that the side can be disposed of in an environmentally friendly manner. When the portable toilet is to be used for different venues and/or events, the side walls can include printed materials to reflect a certain sponsorship and/or event. The top section of the portable toilet can optionally be designed for simple modification to complement a theme of the portable toilet; however, this is not required.

DETAILED DESCRIPTION OF NON-LIMITING EMBODIMENTS

Referring now to the drawings wherein the showings are for the purpose of illustrating one non-limiting embodiment of the invention only and not for the purpose of limiting same, FIGS. 1-27 illustrate one non-limiting embodiment of the portable toilet in accordance with the present invention. Referring to FIGS. 1-6, a non-limiting shape of the portable toilet 100 of the present invention is illustrated. The portable toilet is illustrated as having eight (8) sides and one of the sides includes a door system for the portable toilet; however, this is not required. The sides of the portable toilet are illustrated as generally the same width, thus forming a generally octagon shape; however, this is not required. As can be appreciated, the portable toilet can have a greater or lesser number of sides (e.g., 3 sides, 4 sides, 5 sides, 6 sides, 7 sides, 9 sides, 10 sides, etc.); however, this is not required. As can also be appreciated, one or more of the sides can have a larger or smaller width than one or more other sides of the portable toilet; however, this is not required. As such, the shape of the outer shape of the portable toilet of the present invention is non-limiting. The height of the portable toilet is also non-limiting. Generally the height of the portable toilet in the fully assembled form is about 5-9 feet; however, other heights can be used. The maximum cross-sectional area of the portable toilet in the fully assembled form (e.g., foot print of the portable toilet) is non-limiting. Generally, the maximum cross-sectional area of the portable toilet in the fully assembled form is about 10-40 square feet, typically about 12-30 square feet, more typically about 15-25 square feet, and even more typically about 16-22 square feet; however, other maximum cross-sectional areas can be used. In one non-limiting configuration, the maximum cross-sectional area of the portable toilet in the fully assembled form is about 19-20 square feet. The maximum cross-sectional width of the portable toilet in the fully assembled form is non-limiting. Generally, the maximum cross-sectional width of the portable toilet in the fully assembled form is about 3-8 feet, typically about 3-6 feet, and more typically about 3.5-6 feet; however, other maximum cross-sectional widths can be used. In one non-limiting configuration, the maximum cross-sectional width of the portable toilet in the fully assembled form is about 4-5 feet. As illustrated in FIG. 6, the portable toilet 100 includes a top section 200, a bottom section 300, a side wall 400, a door system 500 and a toilet system 600.

The top section of the portable toilet can have any number of configurations, shapes and sizes. As illustrated in FIG. 6, the top section is a two-piece unit; however, it can be appreciated that the top section can be a single piece unit or be formed of more than two pieces. The lower portion 210 of the top section has a generally circular cross-sectional shape; however, the lower portion 210 can have other cross-sectional shapes (e.g., square, rectangular, oval, polygonal, etc.). The lower portion includes a side wall flange 220 that can fully or partially encircle the body 212 of the lower portion of the top section. As will be described in more detail below, the side wall flange is designed to fit about a top region of the side wall when the lower portion of the top section is positioned on the top edge of the side wall. The side wall flange includes an inner surface 222 that is designed to engage the side wall; however, this is not required. The inner surface of the side wall flange can have a continuous arcuate surface or be formed of a plurality of straight or arcuate sections. As illustrated in FIG. 6, the inner surface of the side wall flange is formed of a plurality of straight or arcuate sections 222a. The number of straight or arcuate sections 222a generally is the same as the number of sides of the portable toilet; however, this is not required. As illustrated in FIGS. 1-6, the portable toilet includes eight (8) sides. As such, the number of straight or arcuate sections 222a of the side wall flange for the top section illustrated in FIGS. 1-6 is eight (8). Also, the length of the straight or arcuate sections is generally the same as the length of a corresponding side wall section. As can be appreciated, the configuration of the inner surface of the side wall flange can be used to properly orient the top section on the side wall; however, this is not required. The body 212 of the lower portion can include a bottom landing 214 that is designed to engage the top edge of the side wall when the top section is placed on the side wall; however, this is not required. The bottom landing extends inwardly from the inner surface of the side wall flange. A wall slot, not shown, can be optionally used to receive a portion of the top edge of the side wall when the top section is fitted on the side wall; however, this is not required. When a wall slot is used, the inner surface of the side wall flange can form one side of the wall slot; however, this is not required.

The top rim 216 of the bottom portion is illustrated as positioned inwardly of the outer surface of the side wall flange; however, this is not required. The configuration of the top rim is non-limiting. Indeed, the inclusion of the top rim is optional. As illustrated in FIG. 1-6, the portable toilet is illustrated as looking similar to a beverage can. As such, the top rim is designed to look similar to the top of a beverage can or some other type of product container. Essentially, the top rim is used to create a certain look for the top section. Therefore, if the top section is to have a flat surface, the top rim on body 212 of the lower portion could be eliminated; however, this is not required.

The body 212 of the lower portion includes a vent tube opening 218 that is used to receive a support portion of a vent tube that is part of the toilet system. As can be appreciated, if the toilet system does not include a vent tube, or the vent tube is directed through the bottom section or the side wall instead of the top section, then the vent tube opening in the lower portion can be eliminated. As can also be appreciated, a vent tube opening can alternatively be positioned in the upper portion 240 of the top section; however, this is not required.

The side wall flange 220 on the lower portion of the top section can optionally include a door frame recess 230 that is designed to receive a top portion of the door system. The size, shape and configuration of the door frame recess are non-limiting.

As can be appreciated, the toilet system opening can have other or additional uses.

Referring now to FIGS. 6, 13 and 14, the side wall 400 of the portable toilet is generally formed of a bendable or otherwise formable material. Generally, the side wall is formed of a recyclable material that allows the side wall to be simply disposed of during the cleaning of the portable toilet; however, this is not required. In one non-limiting arrangement, the side wall is formed of paper board, cardboard material, press board or fiberboard material that includes a cellulose material; however, this is not required. The size, thickness, height, weight, materials, and configuration of the side wall are non-limiting. In one non-limiting configuration, the average thickness of the side wall is about 0.1-3 inches, typically 0.1-2 inches, more typically about 0.2-1 inches, and even more typically about 0.25-1 inches; however, other thicknesses can be used. In another and/or alternative non-limiting configuration, the maximum width or height of the side wall is generally about 3-10 feet, typically 4-8 feet, and more typically about 5-7 feet. In another and/or alternative non-limiting configuration, the maximum length of the side wall is generally about 8-20 feet, typically 10-16 feet, and more typically about 10-14 feet. As illustrated in FIG. 13, the side wall in the non-folded, flat configuration has a generally rectangular configuration. The height of the side wall in this particular non-limiting configuration is about 5.5-7 feet, the thickness of the side wall is about 0.3-0.9 inches, and the length of the side wall is about 11-13 feet.

The front face 410 and/or the back face 420 can include various types of information and/or designs A. The type or color of information and/or the design on the side wall are non-limiting. For example, if a beverage company such as The Coca-Cola Company was sponsoring an event and/or the portable toilets at an event, the front surface of the side wall could be printed to look like a product of The Coca-Cola Company (e.g., Coke can, Diet Coke can, A&W can, Squirt can, Dr. Pepper can, Minute Maid can, PowerAde bottle, etc) Likewise the bottom section and/or top section can be configured, colored, etc. to facilitate in the look of the product of The Coca-Cola Company so as to make the portable toilet better represent the product of the sponsor. The side wall can be simply preprinted prior to shipping to an event; however, it can be appreciated that some or all of the information and/or designs can be applied to the side wall at the event. The flat form or configuration of the side wall facilitates in the ease and convenience of storing and shipping one or more side walls to a particular location. As illustrated in FIG. 14, a plurality of side walls can be stacked together for transport; however, this is not required. As can be appreciated, the side wall can be manufactured and optionally have printing applied at some manufacturing location and the side wall can be shipped to an event location independently of the manner in which the top and/or bottom section is shipped to a particular location. As can also be appreciated, an even location could retain one or more sets of top and bottom sections of the portable toilet and merely order more side walls from a vendor or manufacturer for particular events, and optionally have customized printing applied to the side wall for different events; however, this is not required.

The side wall generally includes scoring 430 to facilitate in the bending of the side wall for connection to the top and bottom section when the portable toilet is assembled; however, this is not required. The scoring can be in the form of slots, grooves and the like. As illustrated in FIGS. 13 and 14, the side wall includes seven regions of scoring; however, other amounts of scoring can be used. The scoring is illustrated as extending the full or substantially the full width of the side wall; however, this is not required. As illustrated in FIG. 6, the side wall is bent at each region of scoring on the side wall. The scoring pattern on the side wall illustrated in FIG. 13 is designed to create six (6) sides 402 having generally the same width and two narrower width sides 404 at each end of the side wall. The two narrower width portions of the side wall are designed to be positioned next to or connect to the door system. As can be appreciated, many other scoring patterns can be used on the side wall to enable the side wall to be bent and configured for use in the portable toilet.

The side wall can optionally include one or more vent openings 440. The vent opening can be designed to receive vent grills or covers 442; however, this is not required.

The side wall can optionally include one or more connection slots 450 that can be used to secure one or more components of the toilet system to the side wall; however, this is not required. The size, shape, configuration and location of the one or more connection slots on the side wall are non-limiting.

Referring now to FIGS. 6 and 15-20, one non-limiting door system 500 that can be used in the portable toilet is illustrated. The size, shape, configuration, color and materials of the door system are non-limiting. The door system is illustrated as including a door frame 510 and two doors 520, 530 that are hingeably or pivotally connected to the door frame. The size, shape, height, thickness, materials, and configuration of the two doors are non-limiting. As illustrated in FIG. 16, the two doors have generally the same shape, size and configuration; however, this is not required. The door frame is illustrated as having two doors; however, it can be appreciated that the door system can include a single door or more than two doors. Each door includes a handle 522, 532 to enable a user to pull open the doors. The size, shape, height, thickness, color, materials, and configuration of each handle are non-limiting. As illustrated in FIG. 16, the two handles have generally the same shape, size and configuration; however, this is not required. As illustrated in FIG. 1, each of the doors plus one of narrower width sides 404 of the side wall form one side of the portable toilet. As such, the two doors of the door system plus the two narrower width sides 404 of the side wall form two sides of the portable toilet and the six sides 402 of the side wall form the other six sides of the portable toilet for a total of eight sides of the portable toilet. As can be appreciated, the side wall and/or the door system can be configured to create less than eight sides or more than eight sides for the portable toilet.

The inner surface of the two doors includes a door lock arrangement 540. The size, shape, color, materials, and configuration of the door lock arrangement, when used, are non-limiting. As illustrated in FIGS. 17, 19 and 20, the door lock arrangement includes a pivoting latch section 542 that is mounted to one of the doors and is designed to pivot between a locked and unlocked position.

Referring to FIGS. 15 and 18, the frame 510 of the door system includes a door cavity 512 that is designed to receive a side portion of a door and to secure the door to the door frame. The connection between the door frame and the door can be any type of connection (e.g., friction connection, adhesive connection, rivet connection, screw or bolt connection, snap fit connection, etc.). The end of the door is illustrated in FIG. 15 to have a narrower thickness for fitting into the door cavity; however, this is not required. As can be appreciated, the door can be connected to the door frame in other or alternative ways. The frame 510 of the door system also includes a wall cavity 514 that is designed to receive a narrower width side 404 of the side wall. The connection between the door frame and the side wall can be any type of connection (e.g., friction connection, adhesive connection, rivet connection, screw or bolt connection, snap fit connection, etc.). As can be appreciated, the side wall can be connected to the door frame in other or alternative ways. As also can be appreciated, the side wall does not need to be connected to the door system.

The door frame can optionally include a pivot or hinge mechanism 516 that enables one portion of the door frame to move relative to another portion of the door frame. The configuration of the pivot or hinge mechanism is non-limiting. As illustrated in FIG. 15, the pivot or hinge mechanism enables each door to swing between an open and closed position.

The configuration of the portable toilet as described above revolutionizes 1) the way in which a portable toilet can be shipped to a particular location, 2) the manner in which the portable toilet can be stored, 3) the manner in which the portable toilet can be assembled and disassembled, 4) the manner in which the portable toilet can be cleaned, and 5) the ability of the portable toilet to be customized for various events.

A portion or all of the top section and base section are generally formed of reusable materials such as a plastic material. The door system is also partially or fully formed of reusable materials. As such, the top section and bottom section of the portable toilet can be assembled and disassemble for a plurality of uses. After each use, the top and bottom section are generally cleaned and stored for later use or cleaned and transported to another location. The individualized top and bottom sections make such sections easier to clean due to the relatively light weight of each section and the ability to move and orient the section for cleaning when the section is not connected to the side wall and/or door system. Prior art portable toilets are not designed to be easily disassembled, thus are cleaned and transported in the fully assembled form. As such, it is more difficult to clean all of the surfaces of prior art portable toilets and more difficult to access and clean all of the regions of the fully assembled prior art portable toilets. The ability to easily disassemble the portable toilet of the present invention into small components results in easier cleaning of such components.

As illustrated in FIGS. 10 and 12, the top and bottom sections can be stacked together for easy transport and storage to form a stacked set 700 of a top and bottom section. The bottom edges of flange 220 on the top section can rest on the top edge of flange 350 on the bottom section as illustrated in FIG. 10 to facilitate in the stacking of a set of top and bottom portions. As illustrated in FIG. 12, the bottom of the bottom section can sit on the top of the section of another set of top and bottom portions so that a plurality of sets of top and bottom portions can be stacked together for easy transport; however, this is not required. This stacking arrangement illustrated in FIGS. 10 and 12 can also be used to save space when storing and/or transporting one or more portable toilets. As illustrated in FIG. 14, a plurality of side walls can be stacked together to facilitate in the easy and convenient storage and/or transport of the side wall. Also, the stacking of a plurality of side walls can be used to save space when storing and/or transporting one or more portable toilets. As will be described in more detail below, a portion of the toilet system can be configured to be collapsible, thus being able to be stored between a set of stacked top and bottom sections as illustrated in FIG. 11; however, this is not required. Such a collapsible toilet system, when used, can be used to facilitate in the easy and convenient storage and/or transport of the components of the portable toilet. As can be appreciated, the modular configuration of the portable toilet results in easier and more convenient storing, transporting and cleaning of the portable toilet as compared to prior art portable toilets.

As mentioned above, the side wall of the portable toilet is intended to be disposed after the portable toilet is disassembled after being used. The side wall is generally formed of a disposable material, and typically a disposable and recycled material. The side wall can also be recycled after use or disposed in a landfill or other disposal location. Since the side wall is not designed to be cleaned after use, the amount of cleaning, the time to clean, and the cleaning materials required to clean the portable toilet are reduced as compared to prior art portable toilets.

As also mentioned above, the portable toilet of the present invention can be easily customized for various sponsors. The side wall of the portable toilet can be formed of a material (e.g., paper board, cardboard, etc.) that can include printing for certain events. When forming the side wall for use with a portable toilet at a certain event, customized printing can be included on the outside and/or inside surfaces of the side wall; however, this is not required. For example, if PepsiCo Americas Foods was sponsoring a certain event, the outside surface of the side walls could include printing to look similar to a PepsiCo Americas Foods product (e.g., Pepsi can, Sierra Mist can, Slice can, Tropicana Can, Ocean spray can, etc.) and the upper portion 240 of the top section can be customized to look similar to the top of the product, thus when the portable toilet is assembled, the portable toilet looks similar to and advertises the product of the sponsor. When the portable toilet is to be used at a different location, the side wall of the portable toilet is disposed of after use, the top section, bottom section, door system (when reusable), and toilet system is cleaned and shipped to the different location. A new side wall can be created and printed to include printing for the different sponsor at the new event location. For instance, if The Coca-Cola Company was sponsoring the event at the new event location, the outside surface of the side walls could include printing to look similar to The Coca-Cola Company product (e.g., Coke can, Diet Coke can, A&W can, Squirt can, Dr. Pepper can, Minute Maid can, PowerAde bottle, etc.) and the upper portion 240 of the top section can be customized to look similar to the top of the product, thus when the portable toilet is assembled, the portable toilet looks similar to and advertises the product of the sponsor. As can be appreciated, if the upper portion 240 is generic for differently sponsored products, the upper portion 240 can be reused at different events; however, this is not required. As can also be appreciated, if the portable toilet is used at a different event that is sponsored by the same product sponsor, the side wall is still generally disposed of after each event and the other reusable components of the portable toilet are generally cleaned after each event. As can be appreciated from this non-limiting example, the outside appearance of the portable toilet of the present invention can be easily customized for use by different sponsors and/or to sponsor different products at one or more events.
