Abstract
A form-coded collar assembly that is configured to be attached around a filling pipe extending into an underground fuel storage tank and comprises a radial lip defining an opening at its open end, and a system having a plurality of such form-coded collar assemblies. The collar assembly has a base plate with a hollow center comprising a greater footprint than the filling pipe; a form-coded collar that corresponds to a substance contained within the underground storage tank; and a sidewall extending between a user-facing surfaces of said base plate and said form-coded collar.
Claims12
A form-coded collar assembly (28) configured to be attached around a filling pipe (12) extending into an underground fuel storage tank (4) and comprising a radial lip (6) defining an opening (2) at its open end, said collar assembly (28) comprising:
- a base plate (14) with a hollow center comprising a greater footprint than the filling pipe (12);
- a form-coded collar (10) that corresponds to a substance contained within the underground storage tank (4);
- and
- a sidewall (8) extending between a user-facing surfaces of said base plate (14) and said form-coded collar (10);
- wherein the collar assembly (28) is formed for attachment around a filling pipe (12), without obstructing the radial lip (6) of said filling pipe (12).
A form-coding system configured for use with a plurality of storage tank filling ports (1) having a plurality of filling pipes (12) extending into an underground fuel storage tank (4) and comprising radial lips (6) defining an opening (2) at its open end, said system, comprising:
- a plurality of form-coded collar assemblies (28), each form-coded collar assembly (28) comprising:
- a base plate (14) with a hollow center comprising a greater footprint than the filling pipe (12);
- a form-coded collar (10) that corresponds to a substance contained within the underground storage tank (4);
- and
- a sidewall (8) extending between a user-facing surfaces of said base plate (14) and said form-coded collar (10),
- wherein the collar assembly (28) is formed for attachment around a filling pipe (12), without obstructing the radial lip (6) of said filling pipe (12),
- wherein at least two of said form-coded collar assemblies (28) include form-coded collars (10) that differ in shape with respect to each other;
- and
- wherein each one of form-coded collar (10) of different shapes corresponds to a different grade or type of fuel.
