Abstract: A leak-proof, interlocking, stackable travel container assembly has a sealing plug and a plurality of travel containers. The sealing plug is designed to create an airtight seal when positioned within an opening. In order to do so, the sealing plug has a first sealing ring, a second sealing ring and a lip. Each of the plurality of travel containers has a neck portion, an opening, a body portion and a base portion. The opening perpendicularly traverses into the neck portion allowing an user to place and remove items within the travel container. When required, the sealing plug is placed within the opening. Next, a protective cap is used to surround the sealing plug. If multiple travel containers are to be used, a base interlocking mechanism and a neck interlocking mechanism are used for interlocking each of the plurality of travel containers.

Abstract: The interlocking, leak-proof storage container assembly includes a lid and a plurality of containers. Let us consider a primary container and a secondary container from the plurality of containers, wherein the primary container is positioned above the secondary container. The lid is utilized to cover an opening of the primary container. A first threading of the primary container engages with a second threading of the lid such that the lid is securely attached to the primary container. When the primary container is interlocked to the secondary container, an opening of the secondary container is concealed by a base section of the primary container. In doing so, a base engagement threading of the primary container engages with a first threading of the secondary container. A carrying case is utilized to store and secure the containers which can have multiple configurations. A cool pack container is used when transporting perishable items.
