A toilet system includes a waterless waste disposal system. A waste liner advancement mechanism is configured to: cover a toilet seat with a liner, capture waste expelled from a user, and mechanically advance the liner into a waste storage area so as to place a fresh liner over the toilet seat after capturing the waste.

The disclosed invention improves on portable toilets for use in hostile environments. The improvements also provide a mechanism for the portable toilet to interface with transportation devices to facilitate transport. The portable toilet is constructed to withstand wind and explosive forces to protect the user. Equipment is also installed in the portable toilet for user safety.

A portable children's toilet system, a handheld children's toilet kit and a pram is disclosed. The portable children's toilet system includes a collapsible children's toilet and a collapsible privacy screen, for providing privacy to a child using the collapsible children's toilet. Advantageously, the portable children's toilet system is easy to carry, for example on a pram, and can be used on demand. As such, reliance on public toilets is avoided.

A dumpster and portable toilet system that includes a chassis with a dumpster mounted thereto, a portable toilet housing portion and a transportation vehicle. The chassis has an attachment region. The dumpster portion has an enclosure that is adapted for receiving refuse. The portable toilet housing portion is removably attachable to the attachment region to form a dumpster and portable toilet system. The portable toilet housing portion has a recess formed therein that is adapted to receive a portable toilet. The transportation vehicle has a hoist mechanism for placing the dumpster and portable toilet system onto the transportation vehicle and moving the dumpster and portable toilet system off of the transportation vehicle.

The invention relates to a public sanitary device (1), comprising a housing with walk-in positions (20, 30), each with a receptacle (21, 31) for human excrement and/or urine. The housing is provided with a first housing part (11) intended for placing underground, a second housing part (12) received movably in the first housing part and a third housing part (13) received movably in the second housing part. The sanitary device comprises a drive for moving the second and third housing parts between an underground rest position and an above-ground position of use. At least one of the walk-in positions is provided with a door for closing the walk-in position. The door comprises at least a first and a second door segment (41, 42), which door segments are movable in longitudinal direction relative to each other. The second housing part (12) comprises the first door segment (41) and the third housing part (13) comprises the second door segment (42).

An odor-proof, splash-proof waterless toilet is formed from a funnel-shaped soft passageway, hereafter referred to as passageway, and a pressing member. Said pressing member is located on one side of the peripheral circle of said passageway, exerting pressure on said passageway, changing the shape of said passageway until said passageway is closed. When said pressing member reduces pressure, said passageway opens. Put simply, the motion, the action of the pressing member increases the pressure on the passageway, which begins to reduce the passageway's ability to allow material to pass through it until it finally closes. A reduction of pressure begins to increase the passageway's ability to allow material to pass through it until it finally opens completely. The said pressing member can be a curved shape, and is tangential to the peripheral circle of said passageway. When the passageway is closed, it prevents odor and splashing.

A portable toilet is disclosed that has a base and a housing with the base and the housing being configured to be stored and transported to a site as a stack of bases and a stack of housings. The toilet is assembled by telescopically installed one of the housings onto a base where the upwardly extending walls of the base are received within the walls of the housing and where the housing is preferably snap locked to the base. The housing may be disassembled from its base by deflecting one of the housing walls outwardly. A method of storing, transporting and assembling such a portable toilet is also disclosed.

A portable toilet is disclosed. The portable toilet includes a portable toilet seat and a portable cabana. The portable toilet seat includes a foldable base in a shape of conventional toilet seat. The foldable base includes seat members defining an open center for excretion of waste therethrough. Further, the portable toilet seat includes a receptacle removably connected to the seat members for covering operative back position of the open center and to receive the waste excreted through the open center. The portable cabana includes an extendable hollow cylindrical body which is extended up to a predetermined height during operation. Further, an opening is provided at an operative top position and at an operative bottom position of the body to allow accommodation of the portable toilet seat within the body.

A lavatory monument assembly that includes an enclosure having front and rear walls and that defines an enclosure interior. A divider wall that extends between the front and rear walls, and a divider door that is movable between closed and opened positions. In the closed position the divider door divides the enclosure interior into first and second lavatory interiors. The divider wall includes first and second sections and the divider door includes first and second portions that meet at an obtuse angle. The divider door is pivotably attached to the divider wall. The front wall includes first and second lavatory doors that are both movable between closed and opened positions and provide access to the first and second lavatory interiors. A first toilet is positioned adjacent the rear wall in the first lavatory interior and a second toilet is positioned adjacent the rear wall in the second lavatory interior.

Aspects are directed to a collapsible privacy structure that has a low profile when in an un-deployed state to preserve the sight lines of observers. The collapsible privacy structure may then be deployed causing a canopy structure to extend upwardly forming an internal volume that provides privacy and seclusion to the user of the structure. The internal volume may be used for a bathroom, a shower, a medical evaluation/treatment space, and/or a changing space. Upon the departure of the user from the internal volume, the collapsible privacy structure may return to the low-profile nature provided by the un-deployed state.
