US 6,851,161 B2 · Sealing closures

Abstract

A reclosable closure consists of two longitudinally continuous strips and which, when facially engaged, are held together by hook and loop fastening principles. The inner side of one strip has two fields of hook-engageable loops, separated by a female seal profile portion. The inner side of the other strip has two fields of molded hook elements arranged to engage the loops to hold the closure in its closed condition, and a central male seal profile portion for engaging the female seal profile portion to form a seal when the closure is closed. Another reclosable closure is held together by hook and loop fastening principles and includes a resilient bead that is compressed between opposing sides of the closure, or between spaced rails of an opposing side of the closure, when the hooks and loops of the closure are engaged. The closure is useful, for example, as a bag closure.

Dependent claims

A fastener product comprising

a first fastener strip having
a strip-form base with a first set of fastener elements carried on one side thereof in two spaced-apart areas;
and
extending along the base between the two areas of the first set of fastener elements, a longitudinal structure integrally molded with and protruding from said side of the base;
and
a second fastener strip having
a strip-form base formed of a plastic resin with a second set of fastener elements carried on one side thereof in two spaced-apart areas and adapted to engage the first set of fastener elements to form a releasable fastening;
and
extending along the base between the two areas of the second set of fastener elements, a surface formed of the resin and arranged to be engaged by the longitudinal structure of the first fastener strip to form a liquid-tight seal between the fastener strips when the first and second fastener strips are engaged;
wherein one of the first and second sets of fastener elements comprise discrete stems arranged in columns and rows, each stem integrally molded with their respective strip-form bases;
wherein the longitudinal structure and engaged surface have complementary profiles that are adapted to interlock when the first and second fastener strips are pressed together.
