Abstract: An embodiment of a container may include a cap and a body. The body may include a bottom and body walls extending from the bottom from proximal ends of the body walls to distal ends of the body walls. The body walls may have a channel disposed within the body walls and proximate the distal ends of the body walls. The channel may have a floor, an opening proximate the distal ends of the body walls, an inner wall including an upper inner rim disposed a first distance from the bottom of the body, and an outer wall including an upper outer rim disposed a second distance from the bottom of the body. The second distance may be greater than the first distance relative to the bottom of the body. The channel may be sized to receive a portion of the cap when the container is in a closed position.

Abstract: An embodiment of a container may include a cap and a body. The cap may include a top portion, cap walls that form an outer perimeter, and a protruding end that forms an inner perimeter sized smaller than the outer perimeter. The body may include a bottom portion and body walls with distal outermost ends that form a cavity and a body perimeter. The body perimeter may be substantially the same as the outer perimeter. The body may also include upper outer and inner rims disposed around the entire distal outermost ends and having a channel between them. The channel may be sized to receive the protruding end in a friction seal when the container is in a closed position. No portion of the cap may be configured to extend into the cavity or beyond the body perimeter in the closed position.
