Abstract

An airtight container for storing comestibles and other articles is disclosed that includes a bottom container portion having a bottom seal section, a top container portion having a top seal section, the top seal section engaged with the bottom seal section to form a container seal at a circular interface, an opening in the top portion, the opening recessed from an outer surface of the top portion and a lid door movably secured to the top portion in which the lid door is configured to selectively engage the opening to form an access seal and in which the top container portion is configured to promote laminar flow across the top portion outer surface.

First claim

What is claimed is:

1. An airtight container, comprising:
a bottom container portion having a bottom seal section;
a top container portion having a top seal section, the top seal section engaged with the bottom seal section to form a container seal at a circular interface;
an opening in the top container portion, the opening recessed from an outer surface of the top container portion; and
a lid door movably secured to the top container portion;
wherein the lid door is configured to selectively engage the opening to form an access seal, and
wherein the outer surface of the top container portion is configured with a curvature to promote laminar ambient air flow across the opening when the lid door is disengaged with the opening, thereby reducing an ingress of ambient air into the airtight container while the lid door is disengaged with the opening.

2. The container of claim 1 , wherein the container seal is an airtight double-seal.

3. The container of claim 1 , wherein the access seal is an airtight seal.

4. The container of claim 1 , wherein the access seal is an airtight double seal.

5. The container of claim 1 , wherein the outer surface of the top container portion configured to promote laminar ambient air flow contains airfoil radiusing.

6. The container of claim 1 , wherein the bottom seal section is permanently secured to the top seal section.

7. The container of claim 1 , wherein the opening in the top container portion is circular.

8. The container of claim 7 , wherein the opening in the top container portion has a diameter that is greater than half a diameter of the top container portion.

9. The container of claim 1 , wherein the opening in the top container portion is elliptical.

10. The container of claim 1 , wherein the lid door engages the opening to form the access seal such that an applied force in the range of 3 to 5 pounds per square inch is required to disengage the lid door from the opening.

11. The container of claim 1 , wherein the lid door is hingedly attached to the top container portion.

12. The container of claim 1 , wherein the lid door is integral the top container portion.

13. The container of claim 1 , wherein a mating feature of the lid door is configured to approach the opening in a substantially vertical direction to engage the opening to form the access seal.

14. The container of claim 1 , wherein the container has a maximum diameter of 3 inches.

15. An airtight container, comprising:
a bottom container portion having a bottom seal section;
a top container portion having a top seal section, the top seal section engaged with the bottom seal section to form a permanent airtight double container seal at a circular interface;
a circular or elliptical opening in the top container portion, the opening recessed from an outer surface of the top container portion; and
a lid door movably secured to the top container portion;
wherein the lid door is configured to selectively engage the opening to form an access seal and further configured to be disengaged from the opening upon a force in the range of 3 to 5 pounds per square inch,
wherein the outer surface of the top container portion is configured with airfoil radiusing to promote laminar ambient air flow across the opening when the lid door is disengaged with the opening, thereby reducing an ingress of ambient air into the airtight container while the lid door is disengaged with the opening, and
wherein the container has a diameter of five inches or less.

16. The container of claim 15 , wherein the access seal is an airtight seal.

17. The container of claim 15 , wherein the access seal is an airtight double seal.

18. The container of claim 15 , wherein a mating feature of the lid door is configured to approach the opening in a substantially vertical direction to engage the opening to form the access seal.
