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 in 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.
Claims38
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 formed by wall panels having an openable mouth and 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 and attaching at least one side of the gasket flange fixing its position within the bag mouth so that the gasket flange does not apply an opening force to the zipper due to internal forces on the wall panels .
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 said gasket flange being secured in part to one of the webs and in part to the other of said webs and extending across said profiles, so that to gain access past said profiles when separated and gasket flange means must be ruptured .
[38. A zipper structure according to claim 37, wherein said gasket flange means is secured in part to one of the webs and in part to the other of said webs and extends across said profiles, so that to gain access part said profiles when separated said gasket flange
- means must be ruptured.] 39. [Zipper structure according to claim 37, wherein] 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;
- said gasket flange [means] is an integrally extruded part of one of said webs and has means permanently securing the gasket flange
- means to the other of said webs. 40. [A zipper structure according to claim 37, wherein] 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 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;
- said gasket flange means comprises a separately formed member, a portion of the gasket flange member being secured permanently to one of said webs and another portion of the gasket flange member secured permanently to the
- other of said webs. 41. [Zipper structure according to claim 37, wherein] 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 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;
- said webs have two sets of spaced complementary profiles with a substantial area of the webs extending intermediate said sets of complementary profiles, and said gasket flange [means] being attached to one of said webs and extending between said profiles of each set and attached to the
- other of said webs in said area intermediate said sets of profiles. 42. A zipper structure according to claim 37, wherein said gasket flange
- [means] is attached to one of said webs. 43. A zipper structure according to claim 42, wherein said gasket flange [means] is attached
- at only one edge to said one web. 44. A zipper structure according to claim 42, wherein said gasket flange [means] extends between said zipper profiles and has opposite edges which are attached to said one web.
- 5. [A zipper structure according to claim 37, wherein] 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 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;
- said gasket flange [means] comprises a pair of gasket flange members, one of which is attached at one edge to one of said webs and the other of
- which is attached at one edge to the other of said webs. 46. A zipper structure according to claim 45, wherein said members extend between said zipper profiles and have opposite edges attached to their respective webs.
