Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
110 words
A device for sterilizing holders containing products with the aid of a heated liquid comprising: an elongate hollow channel; endless conveyor means for conveying the holders through said channel; and duct means for supplying a pressurized heated liquid into the channel at a feeding point located between end portions of said channel wherein said conveyor means further comprises a plurality of blades fixed thereto at regular intervals; said blades closing almost the entirety of a cross-section of the hollow channel throughout the length of said channel, such that during sterilizing operation the pressure of the liquid will progressively decrease from said feeding point to said end portions of said channel.
