Abstract
A sealable container system contains a body and a lid assembly. The body includes an internal volume defined by bottom and side wall(s), bump(s) on the inside surface of the side wall and projecting toward the internal volume, and a lid with outer and inner walls at its bottom side with a channel in-between. A gasket couples to the lid with a wall portion residing within the channel and a lip outside the channel. When the lid assembly is pressed into the body, the lip of the gasket engages the bumps and deforms, and a gap forms between the lip and the side wall, where air in the internal volume exits through the gap. When the lip of the gasket travels past the bumps, the lip fully seats against the inside surface of the side wall, where negative air pressure is imparted to the internal volume of the body.
