Claim 1
Independent Claim
139 words
CANNING APPARATUS COMPRISING INTERCOMMUNICATING ENCLOSURE MEANS CONTAINING A CONTAINER STERILIZING SECTION HAVING AN ENTRANCE FOR CONTAINERS TO BE FILLED, A PRODUCT FILLING SECTION HAVING MEANS THEREIN FOR FILLING THE CONTAINERS WITH A PRE-STERILIZED COOLED PRODUCT, A COVER STERILIZING SECTION, AND A SECTION HAVING MEANS THEREIN FOR APPLYING CONTAINER COVERS TO THE PRODUCT FILLED SAID ENTRANCE AND EXIT BEING UPON THE ATMOSPHERE WHEREBY GAS INTRODUCED INTO THE APPARATUS WILL BE AT SUBSTANTIALLY ATMOSPHERIC PRESSURE; MEANS FOR CONTINUOUSLY CONVEYING CONTAINERS IN SAID APPARATUS, MEANS FOR INTRODUCING GAS INTO SAID APPARATUS HEATED TO A STERILIZING TEMPERATURE AT ATMOSPHERIC PRESSURE SUBSTANTIALLY IN EXCESS OF 212*F., AN ENCLOSED CONTAINER COOLING SECTION BETWEEN AND IN COMMUNICATION WITH THE CONTAINER STERILIZING SECTION AND THE PRODUCT FILLING SECTION, AND WATER SPRAY MEANS IN SAID COOLING SECTION ARRANGED TO DIRECT WATER AGAINST THE OUTSIDE SURFACES OF SAID CONTAINERS.

Claim 3
Dependent Claim
148 words
IN THE CONTINUOUS METHOD OF CANNING WHEREIN A SERIES OF METAL CONTAINERS HAVING INSIDE ENAMEL LININGS IS CONTINUOUSLY MOVED THROUGH AN ENCLOSED STERILE SYSTEM INCLUDING A CONTAINER STERILIZING ZONE IN WHICH THE CONTAINERS ARE HEATED TO STERILIZE THE SAME, A ZONE IN WHICH A PRE-STERILIZED COOLED PRODUCT IS FILLED INTO SAID CONTAINERS WHILE THEY ARECONTINUOUSLY MOVED THROUGH SUCH FILLING ZONE, A COVER STERILIZING ZONE, AND A ZONE IN WHICH THE COVERS ARE APPLIED TO THE FILLED CONTAINERS, ALL OF SAID ZONES BEING IN INTERCOMMUNICATION; THE STEP OF MINIMIZING DAMAGE TO SAID HEATED CONTAINERS FROM THERMAL SHOCK WHICH MIGHT OTHERWISE RESULT FROM THE COOLED PRODUCT CONTACTING THE SAME WHICH COMPRISES COOLING THE CONTAINERS WHILE THEY ARE CONTINUOUSLY MOVED THROUGH SAID ENCLOSED SYSTEM AND BY SUBJECTING SAID HEATED CONTAINERS TO A STERILE AQUEOUS COOLING MEDIUM IN ANOTHER ZONE LOCATED BETWEEN SAID HEATED CONTAINER STERILIZING ZONE AND SAID PRODUCT FILLING ZONE.
