Abstract

An environmentally-friendly portable toilet that is waterless, odorless and cost efficient, that uses a continuous bag supply having a predetermined single dose or portion of at least one chemical automatically deposited therein, the at least one chemical functional to kill pathogens in waste that is deposited through an opening in the seat and a corresponding opening of the continuous bag supply; the waste-filled continuous bag supply is at least temporarily sealed by activation of a mechanical sealing mechanism, and released downwardly into a base section, which is connected to a hard plastic sitting unit, forming an integral, closed system for waterless sanitation.

Claims

1. A method for providing waterless sanitation comprising the steps of:

providing a waterless toilet system comprising a top seating unit matingly connected to a bottom receiving container, the top seating unit further comprising a seat, a lid with a chemical agent dispenser, a lid hinge with a slow-closing mechanism, a lid-tipping mechanism, the hinge connecting the lid to the top seating unit; and

a continuous plastic bag supply;

the bottom receiving container further comprising a mechanical sealing mechanism including rollers and a pedal, the pedal activating the sealing mechanism and the lid-tipping mechanism;

the continuous bag supply feeding into the mechanical sealing mechanism;

wherein the slow-close lid closing mechanism that is restrained from a merely gravity-based closing, such that the pre-calculated amount or dose of the at least one chemical agent or anti-microbial flows or falls out into the bag portion exposed for receiving the waste deposited from the next usage of the waterless toilet apparatus;

advancing the continuous plastic bag supply through the mechanical sealing mechanism;

activating the mechanical sealing mechanism to create a seal a first end of the plastic bag supply to form a bag portion, wherein the seal is created by a nip line formed between two aligned rollers;

providing a bag opening corresponding to a seat opening to allow receiving of a waste into the bag portion;

activating the pedal to tip the lid to close, dispense the chemical agent, and activate and advance the mechanical sealing mechanism to completely enclose the waste within the continuous plastic bag supply by temporarily sealing a second end of the plastic bag supply, when the nip line is formed between two aligned rollers;

advancing the filled portion of the continuous plastic bag supply downwardly into the bottom receiving container and advancing the continuous plastic bag supply.

2. The method of claim 1, wherein the sealing mechanism includes a perforating mechanism such that the continuous plastic bag supply tears along a sealed perforation when sealed and perforated after use.

3. The method of claim 1, wherein the continuous plastic bag supply is perforated and tears along a sealed perforation when sealed after use.

4. A system for providing waterless sanitation comprising:

a waterless toilet further including

a receiving container, a seat, a lid with a chemical dispenser and a slow-close mechanism, a continuous plastic bag supply,

a mechanical sealing mechanism, a lid-tipping mechanism, and a pedal;

the lid-tipping mechanism and the mechanical sealing mechanism both activated simultaneously by the pedal when the pedal is activated;

the lid pivotally connected to the seat and automatically closing in a controlled, smooth manner into a resting position over the toilet when the pedal is activated;

the mechanical sealing mechanism activating and advancing the continuous bag supply to create a faux-flushing action when the pedal is activated;

the chemical dispenser dispensing chemical into the bag when the lid is closed and refilling when the lid is opened;

the continuous plastic bag supply constructed and configured to feed into the mechanical sealing mechanism;

wherein the mechanical sealing mechanism is operable for temporarily sealing a waste-filled portion of the continuous plastic bag supply to form a sealed bag, and advancing the sealed bag into the receiving container;

thereby providing a sanitary, waterless waste disposal system.

5. The system of claim 4, wherein the sealing mechanism includes two aligned rollers that form a nip line to perforate and seal the bag supply when activated into a closed position.

6. The system of claim 4, further including a perforating mechanism such that the continuous plastic bag supply tears along a sealed perforation when sealed and perforated after use.

7. The system of claim 4, wherein the continuous plastic bag supply is perforated and tears along a sealed perforation when sealed after use.

8. An apparatus for waterless, odorless waste receiving and disposal comprising:

a portable toilet that uses a continuous bag supply having a predetermined single dose or portion of at least one chemical automatically deposited therein;

the portable toilet having a foot-operated mechanism to simultaneously close the lid in a controlled, smooth manner, dispense the chemical into the waste, advance the continuous bag supply and activates and advances a bag-sealing mechanism;

the at least one chemical functional to kill pathogens in waste that is deposited through a seat opening in the seat and a corresponding opening of the continuous bag supply;

the waste-filled continuous bag supply is at least temporarily sealed by activation of the mechanical sealing mechanism, and released downwardly into a base section, which is connected to a hard plastic sitting unit, forming an integral, closed system for waterless sanitation.

9. The apparatus of claim 8, wherein the at least one chemical is non-toxic.

10. The apparatus of claim 8, wherein the at least one chemical is environmentally-friendly.

11. The apparatus of claim 8, wherein the at least one chemical is an anti-microbial material for decontaminating waste.

12. The apparatus of claim 8, wherein the waste-filled continuous bag supply is biodegradable.

13. The apparatus of claim 8, wherein the waste-filled continuous bag supply is non-toxic and the at least one chemical includes an anti-microbial agent.

14. The apparatus of claim 8, wherein the sealing mechanism includes two aligned rollers that form a nip line to perforate and seal the bag supply when activated into a closed position.

15. The apparatus of claim 8, further including a perforating mechanism such that the continuous plastic bag supply tears along a sealed perforation when sealed and perforated after use.

16. The apparatus of claim 8, wherein the continuous plastic bag supply is perforated and tears along a sealed perforation when sealed after use.
