parts cup designed to snap over the drain tube and
slowly recirculate solvent around small parts (nuts,
cotter pins, springs, etc.) creating both flushing
and turbulence.
|
|
|
- Roto-cast
remote solvent reservoir. Caps that sealed the pump
tube and the drain opening were stored in molded
depression to store securely while the product was
in use and assure their reuse when the solvent tank
was returned to a store for exchange.
|
|
- Parts
cleaning brush designed with replaceable brush head.
Brush head was a single piece with rolled threads
molded on non-collapsing core with stripper plate,
significantly reducing tooling costs. Brush handle
is two-part, sonically welded, heavy wall copolymer.

Secure
Coolant Container
The
images below illustrate Safety-Kleen’s Secure Coolant
Container with Secondary Containment. It was developed
to replace the traditional use of 55-gallon drums to collect
antifreeze while providing site security. Black Secondary
containment unit was roto-cast of recycled LLDPE. An agreement
with the molder allowed for the recapture and recycling
of the product after its life cycle, creating a closed
loop on the resources contained in the product.
United
States Patent 5,353,951.

Container
for Dry Cleaning Waste
The
images below illustrate Safety-Kleen’s Hazardous Waste
Container for Dry Cleaning Waste. This product was specifically
designed for the company’s dry cleaning waste service
and to replace the conventional 16-gallon steel drum used
for this waste stream. The resulting product reduced hazards
and extended the life of the drum by a factor of 6 (from
1 year to 6 years) the liner was developed with supplier
to prevent chemical permeation using a multi-layered PE-EVOH
material. The interior surface was fluorinated to reduce
absorption and material softening by the chemicals in the
environment. This was a simple appearing yet highly sophisticated
product, and as such won the IDSA’s IDEA, Design of
the Decade Award in 1990. Lead designer on the project was
G. Ira of the product development team at Safety-Kleen.
