  • Patent number: 5285827
    Abstract: A multi-stage, batch or continuous, manual or automated process and apparatus for safely depressurizing, de-capping (decrimping plus pulling caps), and recycling aerosol cans, propellants, solvents, chemicals, dip tubes, and can tops. The apparatus includes a synchronized sorting and loading unit for guiding the cans onto an advancing line. The cans are first depressurized by a vacuum head unit comprising a vacuum seal and a reciprocable hollow needle which punctures the can recessed top cap and removes the propellants by suction for later reuse or disposal. The cans are advanced to a decapping unit where the cap member is removed by decrimping to crack the seal followed by being vertically pulled off without damage to the can's rolled lip.
