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.
Claims18
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.
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.
