Claims
- 1. A suction system for draining waste from a source, said suction system comprising:
- a sealed container including a lid and flexible liner;
- waste inlet means in said lid;
- means in said lid attached to a suction source;
- a freely movable reservoir wholly enclosed within said sealed container for storing waste-treating material wherein said reservoir consists of a hollow tube that is closed at both ends by end caps at least one of which is formed from a material which generally floats when disposed in a liquid to serve as a visual indicator of activation of the waste treating material,
- said end cap defining openable closure means for closing said reservoir until said closure means are manipulated through the flexible liner to open the reservoir to permit dispersion of the waste treating material into the sealed container.
- 2. A suction system as in claim 1 wherein the waste inlet means contains a one-way valve that permits waste to flow only into the container.
- 3. A suction system as in claim 2 wherein the one-way valve is a double slit duckbill valve.
- 4. A suction system as in claim 1 wherein a nonmechanical valve is disposed in flow line with said suction source which prevents suction from being applied when the valve is contacted by waste, said nonmechanical valve containing fluid swellable particles.
- 5. A suction system as in claim 1 wherein the waste inlet means is removably secured to the lid.
- 6. A suction system as in claim 1 wherein said flexible liner is disposable and is secured to said lid.
- 7. A suction system as in claim 1 wherein the reservoir contains a germicide.
- 8. A suction system as in claim 1 wherein the reservoir contains an absorbent.
- 9. A suction system for draining waste from a source that comprises:
- a container that comprises a canister that contains a flexible liner and a lid therefor to which the liner is secured;
- waste inlet means releasably secured to said lid and having a one-way valve that permits waste to flow only into said liner;
- means in said lid attached to a suction source;
- means in said lid to stop suction from being applied in the waste inlet means when the waste in the liner has reached a specified level;
- a freely movable reservoir wholly enclosed within said container for storing waste-treating material wherein said reservoir consists of a hollow tube that is closed at both ends by end caps at least one of which is formed from a material which generally floats when disposed in a liquid to serve as a visual indicator of activation of the waste creating material,
- said end caps defining openable closure means for closing said reservoir until said closure means are manipulated through the flexible liner to open the reservoir to permit dispersion of the waste treating material into the container.
- 10. A suction system as in claim 9 in which the means in said lid for stopping suction from being applied in the waste inlet means comprises a nonmechanical valve to close the means in said lid attached to a suction source.
- 11. A suction system as in claim 10 in which the nonmechanical valve consists of a housing containing polyethylene foam containing swellable moisture-sensitive particles.
- 12. A suction system for draining waste from a source that comprises:
- a container and a lid therefor;
- waste inlet means releasably secured to said lid and having a one-way valve that permits waste to flow only into said container;
- means in said lid attached to a suction source to seal suction from collected waste in the container when the waste in the container has reached a specified level and transfer the suction and waste flow to additional containers that are connected thereto;
- wherein said sealing means consists of a float in the container that is movably mounted to the lid, said lid and float being constructed and arranged to close off the suction and inlet means from the container when it reaches the specified level, but permit flow between said suction and inlet means; and
- a freely movable reservoir wholly enclosed within said container for storing waste-treating material, said reservoir having closure means.
- 13. A suction system for draining waste from a source that comprises: a container and a lid therefor; waste inlet means releasably secured to said lid and having a one-way valve that permits waste to flow into said container but not out of same; means in said lid attached to a suction source to seal suction from collected waste in the container when the waste in the container has reached a specified level and transfer the suction and waste flow to additional containers that are connected thereto; wherein said sealing means consists of a float in the container that is movably mounted to the lid, said lid and float being constructed and arranged to close off the suction and inlet means from the container when it reaches the specified level, but permit flow between said suction and inlet means; and
- tubular paper-like reservoir means closed at both ends and containing waste-treating material, said reservoir means being disposed within said container.
- 14. A suction system for draining waste from a source, said suction system comprising:
- a sealed container including a lid and a flexible liner;
- waste inlet means in said lid;
- means in said lid attached to a suction source;
- a freely movable reservoir wholly enclosed within said sealed container for storing waste-treating material wherein said reservoir consists of a split hollow tube that is enclosed by a wrapper that can be readily opened to empty its contents into the sealed container and
- defining openable closure means for closing said reservoir until said closure means are manipulated through the flexible liner to open the reservoir to permit dispersion of the waste treating material into the sealed container.
