Abstract
Abstract A bag (65) has wall panels (67) defining a receptacle space (70) and providing a bag mouth (71) arrangement between upper end portions of the wall panels (67). A tamper evident, and if desired hermetic seal, non-reclosable closure (78) adjacent to a reclosable zipper (74) and located adjacently below upper end portions of the wall panels is accessible to be opened when the zipper is open. The zipper (74) is arranged for intermittent opening and closing of the bag (65). The non-reclosable closure (78) may be a peel seal or a rupturable connection.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
151 words
A bag having opposed wall panels permanently closed or at least permanently closable at a bottom end of the bag and at opposite sides of the bag, and comprising: a bag mouth arrangement defined by and between upper end portions of said wall panels; reclosable zipper means including complementary interengagable zipper profiles located substantially below the upper ends of said upper end portions and responsive to digital closing pressure for attaining a closed condition of the reclosable zipper means for closing said bag mouth; said zipper means being openable responsive to digital pull apart force for opening said mouth to gain access into contents receiving space within the bag; non-reclosable closure means located in spaced adjacency to said reclosable zipper means for initially maintaining said bag mouth arrangement closed independently of said zipper means; and said non-reclosable closure means being openable by pull-apart force when said reclosable zipper means is open.
Claim 2
Dependent Claim
151 words
A bag having opposed wall panels permanently closed or at least permanently closable at a bottom end of the bag and at opposite sides of the bag, and comprising: a bag mouth arrangement defined by and between upper end portions of said wall panels; reclosable zipper means including complementary interengagable zipper profiles located substantially below the upper ends of said upper end portions and responsive to digital closing pressure for attaining a closed condition of the reclosable zipper means for closing said bag mouth; said zipper means being openable responsive to digital pull apart force for opening said mouth to gain access into contents receiving space within the bag; non-reclosable closure means located in spaced adjacency to said reclosable zipper means for initially maintaining said bag mouth arrangement closed independently of said zipper means; and said non-reclosable closure means being openable by pull-apart force when said reclosable zipper means is open.
Claim 3
Dependent Claim
87 words
A bag having wall panels defining a receptacle space therebetween, and comprising: a bag mouth arrangement defined between upper end portions of said wall panels; one-time openable non-reclosable closure means located substantially below the upper ends of said upper end portions and initially maintaining said mouth arrangement closed; reclosable zipper means also located below said upper ends of said upper end portions and functioning for selectively opening and closing said mouth arrangement; and said non-reclosable closure means being openable only when said reclosable zipper means is open.
Claim 4
Dependent Claim
87 words
A bag having wall panels defining a receptacle space therebetween, and comprising: a bag mouth arrangement defined between upper end portions of said wall panels; one-time openable non-reclosable closure means located substantially below the upper ends of said upper end portions and initially maintaining said mouth arrangement closed; reclosable zipper means also located below said upper ends of said upper end portions and functioning for selectively opening and closing said mouth arrangement; and said non-reclosable closure means being openable only when said reclosable zipper means is open.
Claim 5
Dependent Claim
17 words
A bag according to claim 1 or 2, wherein said non-reclosable closure means comprises a peel seal.
Claim 6
Dependent Claim
26 words
A bag according to claim 1 or 2, wherein said non-reclosable closure means comprises a rupturable web connecting said upper end portions of the wall panels.
Claim 7
Dependent Claim
47 words
A bag according to claim 1 or 2, wherein said non-reclosable closure means includes a web connecting said bag upper end wall panel portions, and a line of weakening along said web and which line of weakening is rupturable by pull apart force applied to said web.
Claim 8
