Abstract
A spill containment system is attachable to a riser pipe with an axially moveable seal. The spill containment system allows access to a drop tube in the riser pipe via a removable liquid communication assembly. The spill containment system includes a sealed interstitial space, which remains sealed during installation, service and use of the system. The spill containment system is protected by a weather resistant cover assembly.
Claims19
A fluid spill collector assembly comprising:
- a primary receptacle including:
- an upper primary receptacle end having an upper primary receptacle opening;
- a lower primary receptacle end having a lower primary receptacle opening;
- a primary receptacle wall extending between said upper and lower primary receptacle ends, said primary receptacle wall defining a primary receptacle cavity;
- a secondary receptacle including:
- an upper secondary receptacle end having an upper secondary receptacle opening;
- a lower secondary receptacle end having a lower secondary receptacle opening;
- and
- a secondary receptacle wall extending between said upper and lower secondary receptacle ends, said secondary receptacle wall defining a secondary receptacle cavity,
- said primary receptacle received within said secondary receptacle cavity, said upper primary receptacle opening sealingly coupled to said upper secondary receptacle opening to form a sealed upper end of the assembly;
- and
- a single, unitary tank adapter having a base platform with an aperture extending therethrough, said base platform sealingly coupled to said primary lower receptacle opening and said lower secondary receptacle opening to form a sealed lower end of the assembly,
- said sealed upper end and lower ends of the assembly cooperating to form a sealed interstitial space between said primary receptacle wall and said secondary receptacle wall,
- wherein said primary receptacle cavity remains in fluid communication with said upper primary receptacle opening and said aperture of said tank adapter while said interstitial space is sealed.

A fluid spill collector assembly comprising:
- a stationary collar having an inner peripheral surface with at least one radial collar aperture formed therein;
- and
- a double-walled spill container assembly comprising:
- an outer receptacle having a first open upper end, said outer receptacle sized to be receivable within said collar;
- an inner receptacle having a second open upper end, said inner receptacle coupled to said outer receptacle to create a sealed interstitial space therebetween;
- and
- a seal coupled to at least one of said outer receptacle and said inner receptacle, said seal slidably engageable with said inner peripheral surface of said collar to create a fluid tight seal between said collar and said spill collector assembly,
