Closure systems and insulating devices having closure systems

1. A closure system comprising:

a first flange having a first end, a second end and a first engagement mechanism disposed between the first end and the second end;

a second flange having a first end, a second end and a second engagement mechanism disposed between the first end and the second end;

the first engagement mechanism configured to engage the second engagement mechanism, and the closure system having an open position wherein first engagement mechanism is substantially disengaged from the second engagement mechanism and a closed position wherein the first engagement mechanism is substantially engaged with the second engagement mechanism;

a slider configured to selectively engage the first engagement mechanism and the second mechanism when moved in a first direction and disengage the first engagement mechanism from the second engagement mechanism when moved in a second direction;

wherein the closure system is substantially watertight in the closed position;

wherein the closure system is configured to bias open by a resilient member when the closure system is unzipped; and

wherein the closure system is configured to open to an angle of at least 45 degrees and remain in an open position.

2. The closure system of claim 1 , wherein the closure system is watertight up to 7 psi above atmospheric pressure.

3. The closure system of claim 1 , wherein the closure system is watertight up to 2 psi to 14 psi above atmospheric pressure.

4. The closure system of claim 1 , wherein each of the first end and the second end of the closure system comprise a flexible material.

5. The closure system of claim 1 , wherein each of the first engagement mechanism and the second engagement mechanism comprise a flexible material.

6. The closure system of claim 1 , wherein the first engagement mechanism and the second engagement mechanism comprise zipper teeth.

7. A container comprising: an outer shed;

an opening extending through the outer shell; and

a closure system adapted to substantially seal the opening, the closure system comprising:

a first flange engaged with the container, the first flange having a first end, a second end and a first engagement mechanism disposed between the first end and the second end;

a second flange engaged with the container, the second flange having a first end, a second end and a second engagement mechanism disposed between the first end and the second end;

the first engagement mechanism configured to engage the second engagement mechanism, and the closure system having an open position wherein first engagement mechanism is substantially disengaged from the second engagement mechanism and a closed position wherein the first engagement mechanism is substantially engaged with the second engagement mechanism;

a slider configured to selectively engage the first engagement mechanism and the second mechanism when moved in a first direction and disengage the first engagement mechanism from the second engagement mechanism when moved in a second direction;

wherein the container is substantially watertight when the closure system is in the closed position;

wherein the closure system is configured to bias open by a resilient member when the closure system is unzipped; and

wherein the closure system is configured to open to an angle of at least 45 degrees and remain in an open position.

8. The container of claim 7 , wherein the closure system is watertight up to 7 psi above atmospheric pressure.

9. The container of claim 7 , wherein the slider is configured to removably engage the first and second flange with at least one of: press fitting, snap fit mechanisms or mechanical fasteners.

10. The container of claim 7 , wherein the first engagement mechanism and the second engagement mechanism comprise zipper teeth.

11. A container comprising: an outer shed;

an opening extending through the outer shell; and

a closure system adapted to substantially seal the opening, the closure system comprising:

a first flange engaged with the container, the first flange having a first end, a second end and a first engagement mechanism disposed between the first end and the second end;

a second flange engaged with the container, the second flange having a first end, a second end and a second engagement mechanism disposed between the first end and the second end;

the first engagement mechanism configured to engage the second engagement mechanism, and the closure system having an open position wherein first engagement mechanism is substantially disengaged from the second engagement mechanism and a closed position wherein the first engagement mechanism is substantially engaged with the second engagement mechanism;

a slider configured to selectively engage the first engagement mechanism and the second mechanism when moved in a first direction and disengage the first engagement mechanism from the second engagement mechanism when moved in a second direction;

wherein the container is substantially watertight when the closure system is in the closed position;

wherein the closure system is configured to bias open by a resilient member when the closure system is unzipped;

wherein the closure system is configured to open to an angle of at least 45 degrees and remain in an open position;

wherein the first engagement mechanism and the second engagement mechanism comprise zipper teeth; and

wherein the zipper teeth comprise a flexible material.

12. The container of claim 11 , wherein the closure system is watertight up to 7 psi above atmospheric pressure.

13. The container of claim 12 , wherein the closure system is configured to deform while remaining sealed.
