Peel seal tamper evident slider bag
View Patent ↗Both apparatus and methods for flexible recloseable containers with peel seals are disclosed. In one embodiment, the peel seal has a height greater than the height of the fastener strip flange to which it is attached. The upper portion of the peel seal is attached to the flange. The lower portion of peel seal is attached to a wall of the container. Also disclosed are methods for fabricating containers, and also for forming, filling, sealing a container with a product therein.
1. An apparatus comprising:
a first fastener strip including a first closure element and a first flange depending downwardly from said first closure element, said first flange having a first inner face;
a second fastener strip including a second closure element and a second flange depending downwardly from said second closure element, said second flange having a second inner face; said first closure element and said second closure element being adapted and configured for interlocking to each other, said first fastener strip and said second fastener strip being at least partially interlocked with each other, said first inner face facing toward said second inner face when said first fastener strip and said second fastener strip are at least partially interlocked with each other;
a plurality of sliders slidably mounted to said first and second fastener strips, said sliders being adapted and configured to slide in a first direction along said first and second fastener strips and interlock said first closure element to said second closure element and slide in a second direction opposite to the first direction to unlock said first closure element from said second closure element; and
a peel seal extending between said first flange and said second flange and attached to at least one of the said first flange or said second flange along the corresponding inner face, the one said flange having a bottommost edge, said peel seal extending below the bottommost edge.
2. The apparatus of claim 1 wherein the peel seal has a height which is greater than the height of the one said flange of the fastener strip.
3. The apparatus of claim 1 wherein said peel seal extends at least 0.2 inches below the bottommost edge.
4. The apparatus of claim 1 wherein said peel seal has a length which is substantially the same as the length of said fastener strip of the one said flange.
5. The apparatus of claim 1 wherein said peel seal is a three layer laminate coextruded with said fastener strip of the one said flange.
6. An apparatus, comprising:
a first fastener strip including a first closure element and a first flange depending downwardly from said first closure element, said first flange having a first inner face;
a second fastener strip including a second closure element and a second flange depending downwardly from said second closure element, said second flange having a second inner face; said first closure element and said second closure element being adapted and configured for interlocking to each other, said first fastener strip and said second fastener strip being at least partially interlocked with each other, said first inner face facing toward said second inner face when said first fastener strip and said second fastener strip are at least partially interlocked with each other;
a plurality of sliders slidably mounted to said first and second fastener strips, said sliders being adapted and configured to slide in a first direction along said first and second fastener strips and interlock said first closure element to said second closure element and slide in a second direction opposite to the first direction to unlock said first closure element from said second closure element; and
a peel seal extending between said first flange and said second flange and attached to one of said first flange or said second flange along the corresponding inner face, said peel seal not being attached to the other of said first flange or said second flange.
7. The apparatus of claim 6 wherein the peel seal has a height which is greater than the height of the one said flange of the fastener strip.
8. The apparatus of claim 6 wherein the one said flange has a bottommost edge, and said peel seal extends at least 0.2 inches below the bottommost edge of the one said flange.
9. The apparatus of claim 6 wherein said peel seal has a length which is substantially the same as the length of said fastener strip of the one said flange.
10. The apparatus of claim 6 wherein said peel seal is a three layer laminate coextruded with said fastener strip of the one said flange.
