Abstract
A bag has wall panels defining a receptacle space and providing a bag mouth arrangement between upper end portions of the wall panels. A tamper evident, and if desired hermetic seal, non-reclosable closure adjacent to a reclosable zipper and located adjacently below upper end portions of the wall panels is accessible to be opened when the zipper is open. The zipper is arranged for intermittent opening and closing of the bag and its opposite ends are sealed into the side edges of the bag. The non-reclosable closure may be a peel seal or a rupturable connection.
Claims5
A bag having opposed wall panels secured together and defining a receptacle space therebetween, and comprising:
- a bag mouth defined between upper end portions of said wall panels which extend between opposite sides of the bag;
- a one-time openable non-reclosable peel seal closure means extending in a relatively narrow band from side-to-side of the bag and securing said panels together substantially below the upper ends of said upper end portions and initially maintaining said mouth fixedly closed;
- reclosable zipper means located below said upper ends of said upper end portions, but above said peel seal closure means and functioning for initially maintaining said upper end portions against access to said non-reclosable peel seal closure means;
- said zipper means comprising complementary extruded plastic profiled fastener strips one of which is permanently connected to the inside surface of the upper end portion of one of said wall panels and the other of which is permanently connected to the inside surface of the upper end portion of the other of said wall panels;
- said strips having profiles which are reclosably interlockable by digital pressure applied inwardly toward the strips on the outer faces of the wall panel areas in line with the fastener strips, one being adapted to be manually pulled open and reclosed for selectively opening and closing said mouth after said non-reclosable peel seal closure has been opened;
- said zipper strips having opposite ends sealed into side edges of said bag;
- said reclosable zipper means being openable responsive to digital pull apart force applied to said upper end portions of the wall panels for gaining access to said non-reclosable peel seal closure means;
- and
- said non-reclosable peel seal closure means being operable by continuing pull apart force applied to said upper end portions of said wall panels, after said reclosable zipper means has been pulled open, for gaining complete access into said receptacle space, and said reclosable zipper means being thereafter reclosably closable as the sole closure for the bag mouth.
