DESCRIPTION:
BRIEF SUMMARY
This invention relates to portable human waste collection devices, commonly known as portable toilets, and relates particularly but not exclusively to a non-flushing portable toilet utilising disposal bags for collection, storage and/or transport of the disposable waste.
Prior known portable toilets either operate on a flushing system requiring a water supply and include a separate waste holding tank which can be disconnected from the device for subsequent disposal of the waste or are simple devices merely having a plastics material waste bag suspended or removably attached therein. Such portable toilets are of limited use when prolonged usage is required or when no water supply is available for flushing. Such circumstances may be encountered in a natural disaster area where water supply and sewerage systems are disrupted.
Illustrative of such prior art portable toilet devices are those devices described in U.S. Pat. Nos. 3,859,672, 4,199,826, 3,801,991, Canadia Patent Nos. 1188456 and 1157207 and German Patent No. 3128075. Other prior art references of relevance are U.S. Pat. No. 2,801,426 to La Gorce and U.S. Pat. No. 3,943,578 to Miya.
The La Gorce Patent discloses a disposable bag toilet having inter alia a hinged seat and a bag having two draw strings. The bag has a normally open top. Operation of the hinged lid causes the draw strings to close the bag. Operation of the lid does not and cannot return the bag to its "normally open" or ready-for-use position.
The Miya Patent discloses a throttle valve for fitment between a toilet seat and a reservoir for excreta. The throttle valve comprises two coaxial cylindrical membranes which can be twisted to either an open or closed position.
The lower membrane is closed during the use by rotating a flange to appropriate angular position so as to temporarily hold the faeces thereon while bad odor from the reservoir is prevented from rising therethrough. After use, the flange is rotated so as to open the lower cylindrical membrane for discharging the faeces thereon into the reservoir while the upper cylindrical membrane is closed to prevent bad odor from rising into the lavatory room and prevent the faeces to be viewed by the user. After discharge of the faeces into the reservoir, the lower cylindrical membrane is closed by rotating the central flange to be ready for the next use. The throttle device has no disposable bag for collection and ready removal of waste material.
It is therefore one object of the invention to provide a portable toilet device which overcomes or substantially reduces disadvantages of prior art devices suitable for use in disaster areas or, as more normally, for use with caravans, campervans, mobile homes and on boats.
The present invention therefore in one preferred form provides a portable toilet device having, in-use, a disposable plastic material waste receiving bag therein, said device comprising an upper section and a lower section adapted to be movable with respect to each other from an open or in-use position to a closed or non-use position or vice versa wherein movement of the device from the in-use to the non-use position causes a temporary closure or sealing of the bag and wherein movement of the device from the non-use to the in-use position causes the bag to open ready for use.
Preferably the lower section includes an open canister or receptacle to support or position the suspended bag. Preferable the movement of the device from the open to the closed position causes a turnable, on which the canister or receptacle is disposed to rotate, providing twisting action to temporarily close or seal the bag.
Preferably the upper section includes a seat section and a lid suitably hinged to the device as is customary. Preferably the lid of the device contains a compartment for storage of toilet paper or tissues and also a dispenser for holding and dispensing a gelling agent, or a gelling agent and a disinfectant, or deodorant.
The present invention also provides a portable toilet device having, in-use, a disposable plastic material waste
