Forming mold with recess having snap-fit end seal
First Claim
1. A mold for forming an object, comprising:
- (a) a mold cavity, and (b) a recess located on a surface of said mold cavity, said recess having at least one end and suitable for receiving a fastening assembly having at least one end, and (c) an end wall located at one said end of said recess below the uppermost point of said recess, said end wall having a projection thereon in order to frictionally engage and seal one said end of said fastening assembly against fouling during a forming process, said projection being defined by one portion of the surface of said end wall extending inward toward the interior of said recess and another portion of the surface of said end wall extending outward away from the interior of said recess.

Abstract
The invention is a seat bun mold (10) with a recess (12) suitable for containing a fastener strip (18) to be molded into the seat bun, the recess (12) having an end wall (14) shaped so as to provide a snap-fit seal against the end of the fastener strip (18), in order to prevent fouling of the fastener strip (18) during the seat bun molding process. End wall (14) extends from the bottom to the top of the recess (12), and substantially curves inward along its lower extent and outward along its upper extent. The end of fastener strip (18) is snapped into recess (12) by first aligning fastener strip (18) over recess (12) and then exerting downward pressure. The tension of the end of fastener strip (18) against end wall (14) forms a seal to prevent intrusion of liquid molding material through end wall (14) of recess (12).
