Abstract:
A fastener assembly, comprising:(a) a mold form including a mold cavity defined by upright mold walls terminating at upper wall corner edges; and (b) a fastener member of being secured to the surface of a foam body during a molding process in the mold form, comprising: (i) an elongate base having upper and lower opposed faces; (ii) fixating elements positioned on the lower face of the base for being positioned within and protected by the walls of the mold cavity against foam contamination during the molding process; (iii) first and second opposed, elongate sealing ramps positioned on the upper face of the base by respective proximal ends and diverging outwardly and upwardly at an angle oblique to the base and defining respective outwardly-extending distal ends; (iv) the base sized to fit within the mold cavity of the mold form with outer surfaces of the respective first and second ramps engaging and sealingly contacting respective upper wall corner edges of the mold at points of contact intermediate the proximal and distal ends thereof; and (v) a magnetically-attractable material fixed to the base for being magnetically attracted to a magnet positioned in the mold cavity to thereby seal the cavity against the sealing ramps to prevent foam from entering the mold cavity at a contact line between said sealing ramps and said respective upper wall corner edges of the mold.
