Abstract
A watertight closure for a reclosable package has first and second mutually interlocking profiles. Together, the profiles have two sets of interlocking members, one on either side of a central portion. There, at least one profile has a collapsible member in its central portion. The other profile may have a compressing member or a collapsible member opposite to the collapsible member, or it may have neither. In any event, when the first and second mutually interlocking profiles are joined to one another, the collapsible member encounters and compresses against the other profile to create a watertight seal.

A watertight closure for a reclosable package comprising:
- a first and a second mutually interlocking profile, said first and second mutually interlocking profiles together having two sets of interlocking members separated from one another by a central portion thereof, each of said first and second mutually interlocking profiles having a web and two interlocking members separated from one another thereon, said web of said first mutually interlocking profile being in a substantially parallel orientation to said web of said second mutually interlocking profile,
- wherein each of said interlocking members of said first and second mutually interlocking profiles is located on a side of said web facing toward the web of the other mutually interlocking profile;
- a first collapsible member on the web of said first mutually interlocking profile between its respective interlocking members;
- and
- a second collapsible member on the web of said second mutually interlocking profile between its respective interlocking members, said second collapsible member being opposite said first collapsible member, said first and second collapsible members encountering and compressing one another when said first and second mutually interlocking profiles are joined to one another to create a watertight seal in said central portion thereof.
A reclosable package comprising;
- a first wall and a second wall joined to form an enclosure with a mouth defined by wall edges, and
- a watertight closure for selectively opening and closing said reclosable bag, said watertight closure comprising a first and a second mutually interlocking profile, said first profile extending along an internal surface of said first wall adjacent to said mouth and said second profile extending along an internal surface of said second wall adjacent to said mouth,
- wherein said first and second mutually interlocking profiles together have two sets of interlocking members separated from one another by a central portion thereof, each of said first and second mutually interlocking profiles having a web and two interlocking members separated from one another thereon, said web of said first mutually interlocking profile being in a substantially parallel orientation to said web of said second mutually interlocking profile,
- wherein each of said interlocking members of said first and second mutually interlocking profiles is located on a side of said web facing toward the web of the other mutually interlocking profile;
- wherein a first collapsible member is on the web of said first mutually interlocking profile between its respective interlocking members;
- and
- wherein a second collapsible member is on the web of said second mutually interlocking profile between its respective interlocking members, said second collapsible member being opposite said first collapsible member, said first and second collapsible members encountering and compressing one another when said first and second mutually interlocking profiles are joined to one another to create a watertight seal in said central portion thereof.
