Abstract
A bag with an openable mouth carries a reclosable extruded plastic zipper inside the mouth. The zipper has complementary profiles separably interlockable in a closed condition of the zipper. A gasket flange structure is separably sealingly grippingly interengageable by and between the profiles in the closed condition of the zipper, and may also serve as a tamper evident or tamper discouraging device.
Claims46
A bag or package having an openable mouth carrying an elongate reclosable extruded plastic zipper extending across the inside of said mouth.
- said zipper having complementary profiles separably interlockable in a closed condition of the zipper;
- and
- gasket flange means extending along substantially the full length of the profiles for separably sealingly gripping interengagement by and between said profiles in said closed condition of the zipper.
A method of making a bag or package having an openable mouth carrying an elongated reclosable extruded plastic zipper extending across the inside of said mouth, comprising:
- providing said zipper with complementary profiles separably interlockable in a closed condition of the zipper;
- and
- providing gasket flange means extending throughout the length of said zipper for separably sealingly gripping interengagement by and between said profiles in said closed condition of the zipper.
In a bag or package having an openable mouth carrying an elongate reclosable extruded plastic zipper inside said mouth;
- said zipper comprising a generally arrowshape profile and a generally groove shaped complementary profile and said profiles being interlockable in a closed condition of the zipper;
- and
- gasket flange means extending throughout the length of said zipper for separably sealingly gripping interengagement by and between said profiles in said closed condition of the zipper, and said profiles having at least a pair of cooperating surfaces which grip said gasket flange means sealingly therebetween.
An elongate reclosable extruded plastic zipper structure for bag or package use:
- said zipper structure having opposed webs with complementary profiles separably interlockable in a closed condition of the zipper structure;
- and
- gasket flange means extending along substantially the full length of the profiles for separably sealingly gripping interengagement by and between said profiles in said closed condition of the zipper structure.
