- 2. The assembly of claim 1, in which the frame includes at least one slot, and in which the receptacle includes a tab adapted to lockingly engage the slot, thereby to secure the receptacle in the installed position.
- 3. The assembly of claim 2, in which the tab is toollessly releasable to disengage from the slot.
- 4. The assembly of claim 1, in which the top member of the frame further defines the receptacle engaging portion.
- 5. The assembly of claim 4, in which the receptacle includes a flange defining the abutting portion of the receptacle.
- 6. The assembly of claim 1, in which the vacuum waste system further comprises a rinse valve and a rinse fluid pipe, and in which the receptacle further comprises a rinse fluid dispenser adapted for toollessly releasable attachment to the rinse fluid pipe.
- 7. The assembly of claim 1, in which the receptacle is made of a plastic material.

- 10. A method of toollessly replacing a receptacle of a waste receptacle assembly used in a vacuum toilet system having an inlet coupling, the waste receptacle assembly including a frame including at least two vertical supports and a top member attached to the at least two vertical supports defining an opening, the frame further having a receptacle engaging portion, the receptacle being sized for at least partial insertion through the frame top member opening and having an abutting portion positioned to engage the receptacle engaging portion of the frame to maintain the receptacle in an installed position, the receptacle further having an outlet sized and adapted for releasable sealing engagement with the inlet coupling, the method comprising:lifting the receptacle while leaving the frame in place so that the abutting portion of the receptacle disengages from the receptacle receiving portion of the frame and the receptacle outlet disengages from the inlet coupling; withdrawing the receptacle through the frame top member opening to remove the receptacle from the frame; providing a new receptacle sized for at least partial insertion through the frame top member opening having an abutting portion positioned to engage the receptacle engaging portion of the frame and an outlet sized to sealingly engage the inlet coupling; and inserting a new receptacle at least partially through the frame top member opening so that the abutting portion of the new receptacle contacts the receptacle engaging portion of the frame and the outlet of the new receptacle engages the inlet coupling.
- 11. The method of claim 10, in which the frame includes at least one slot, and in which each of the receptacle and new receptacle includes a tab adapted to lockingly engage the slot, wherein the tab of the receptacle is removed from the slot during the lifting step and the tab of the new receptacle is inserted into the slot during the inserting step.
- 12. The method of claim 10, in which the top member of the frame further defines the receptacle engaging portion.
- 13. The method of claim 12, in which the each of the receptacle and new receptacle includes a flange defining the abutting portion.
- 14. The method of claim 10, in which the vacuum waste system further comprises a rinse valve and a rinse fluid pipe, and in which each of the receptacle and new receptacle further comprises a rinse fluid dispenser, the method further comprising detaching the rinse fluid dispenser of the receptacle from the rinse fluid pipe prior to the lifting step and attaching the rinse fluid dispenser of the new receptacle to the rinse fluid pipe after the inserting step.
- 15. The method of claim 10, in which the receptacle is made of a plastic material.
- 16. The method of claim 10, in which the receptacle is made of a thin-walled steel.
