Abstract:
1. A flangeless, reclosable fastener comprised of: (a) a first elongated fastener strip, and a second elongated fastener strip, said first elongated fastener strip being formed of a plurality of adjacent and contiguous, C-shaped closure elements, each of said C-shaped closure elements having an opening that faces a first direction, said openings defining a first side of said first elongated fastener strip, an upper and lower extent of the adjacent and contiguous C-shaped closure elements defining a width of said first elongated fastener strip, at least one of said C-shaped closure elements being formed to have a hook-shaped protuberance that is shaped and sized to engage a complementary recess in the second elongated fastener strip; (b) said second elongated fastener strip being formed of a plurality of adjacent and contiguous, C-shaped closure elements, each of said C-shaped closure elements having an opening facing a second direction that is opposite said first direction, said openings of said plurality of C-shaped closure elements defining a first side of said second fastener strip, an upper and lower extent of the plurality of contiguous C-shaped closure elements defining a width of said second elongated fastener strip, at least one of said C-shaped closure elements being formed to have a hook-shaped protuberance that is shaped and sized to engage a complementary recesses in said first elongated fastener strip, said first and second fastener strips having recesses that are substantially congruent to the hook-shaped protuberances; (c) when said first elongated fastener strip and second elongated fastener strips are engaged, the upper extent of said C-shaped closure elements of said first elongated fastener strip and the lower extent of said C-shaped closure elements of said second elongated fastener strip define the width of said flangeless, reclosable fastener; (d) the first and second elongated fastener strips having back sides with curved ridges to facilitate a substantially airtight and watertight seal to an inside surface of a front wall and a back wall of bag containing the reclosable fastener; and (e) wherein the engaged hook-shaped protuberances and recesses in the first elongated fastener strip and in the second elongated fastener strip are sized, dimensioned, and arranged to provide a substantially airtight and substantially watertight seal.
