Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
119 words
A blow-mold of a configuration suitable for forming a heat-set container including at least one elongated recessed panel section, comprising: plural mold members defining a mold cavity therebetween, and having at least one elongated removable insert member projecting from adjacent surfaces of said mold members for defining said panel section; said blow-mold having heating means for heating walls defining said mold cavity; and said insert member comprising means suitable for maintaining said insert member at a temperature above ambient but different from the temperature of said adjacent mold member surfaces, the back of said insert member adjacent one of said walls having a recessed portion to reduce heat transfer from said adjacent mold member surfaces to said insert member.
Claim 2
Dependent Claim
119 words
