Abstract: A container for storing matter provides a container body having a resilient flange protruding outward therefrom to form a seal between the container body and a mating closure. The resilient flange is deflected by the inner surface of the mating closure to form a first releasable seal between the closure and the container body. The resilient flange includes an aspect ratio of length divided by thickness. A second releasable seal is formed in some embodiments between the upper edge of the side wall and the closure when the mating closure is positioned on the container body.

Abstract: An improved container provides a container body and a closure. In some embodiments, a scooping utensil retainer is disposed on the closure. The scooping utensil retainer includes opposing flanges protruding from the closure surface. A flange rib protrudes from the first flange into the flange gap, extending from the closure surface to the distal end of the flange. A tapered retainer gap is provided between flanges for resiliently clamping the handle of a scooping utensil. In some embodiments, the closure can include an annular ridge shaped for engaging a downwardly extending skirt on a like container when two like containers are vertically stacked. In some embodiments the container body includes an in-mold label affixed to a substantially straight side wall, the in-mold label covering at least about 95% of the exterior surface area of the container body.
