Abstract

An improved reclosable fastener profile assembly is provided, said assembly comprising a continuous supply of a first profile strip this first profile strip being substantially flat but having at least one rib that extends from the surface of first strip; and a continuous supply of a second profile strip opposite the first strip; this second strip being substantially flat but having at least two ribs that extend from the surface of this second strip. The rib of the first strip and the ribs of the second strip are adapted to sealingly engage and maintain an airtight seal when so engaged. A compression molded segment seal portion fuses the first profile strip, the second profile strip and the ribs of the first profile: strip and second strip. The compression molded segment seal includes a fused section of the first and second profile strips formed through the application of heat and pressure without further filling material or plastic. This fused section is substantially flattened to form an airtight seal of the first and second profile strips less than the combined thickness of the first and second profile strips, without distorting said ribs of said first and second profile strips outside of said fused section, thereby maintaining the airtight seal of the first and second profile strips when interlocked. The compression molded segment seal portion further has a thickness less than the combined thickness of the first profile segment and the second profile segment, so as to allow easier sealing of the ends of the fastener strips to the side walls of a reclosable bag.
