Modular Snack Container with Elastomeric Seals for Spill Prevention

The patent combines multiple protective and handling features into a single integrated container system. The rimless construction merges the rim structure with the sidewall, eliminating protruding edges that cause spills. The handle is integrated into the container body through a recess, creating a unified structure that provides both containment and easy gripping in one design element.

The container design incorporates multiple functions within a single structure: the rimless sidewall provides both containment and spill prevention, the integrated recess handle provides both structural attachment and improved gripping, and the overall design serves both drinking and snack containment purposes. This multi-functional approach enhances reliability without proportionally increasing complexity.

The handle recess is positioned asymmetrically on the container body, creating a natural gripping zone that is optimized for small hands. The recess breaks the symmetry of the cylindrical container body, providing an asymmetric feature that is specifically designed to accommodate limited dexterity while maintaining the overall simplicity of the container structure.

The handle recess creates a flexible gripping zone in the container wall, allowing the thin film of the container material to deform and conform to the user's hand. This flexibility enables easy gripping without adding rigid structural complexity, as the container wall itself becomes the handling interface.

The patent extracts the rim element from the traditional container design, removing the protruding rim structure that causes spills. By taking out the rim and integrating its functional requirements directly into the sidewall structure, the design achieves spill prevention while simplifying the molding process, as fewer distinct structural elements need to be formed.

The rimless design changes the geometric parameters of the container opening, transitioning from a protruding rim structure to a flush or recessed opening. This parameter change eliminates the spill-causing geometry while maintaining manufacturability through standard molding techniques, as the new geometry is actually simpler to form than traditional rimmed containers.
