Disclosed herein is an airtight container. The fastening structure comprises a body with a rim integrally formed at a periphery of an opened upper end of the body, a lid with a channel portion formed at a periphery of the lid to be fitted into the body and maintain an airtight seal between the body and the lid, one or more foldable fastening ribs, each being protruded from the lid in a lateral direction as an integral part of the lid and having a fastening slit perforated through the fastening rib in a lengthwise direction, and one or more fastening pieces corresponding to the fastening ribs, each being protruded from the body in the lateral direction and inserted onto the corresponding fastening slit of the fastening rib, wherein each of the fastening ribs is formed with one or more reinforcing rib-receiving portions of a semi-circular shape, each of the reinforcing rib-receiving portions opened toward a central lower portion of the fastening slit in a lengthwise direction through the fastening rib, and wherein each of the fastening pieces is a protruded piece protruded in a lateral direction at a position corresponding to the fastening slit of the fastening rib, and is integrally formed with a reinforcing rib being a thick portion downwardly protruded from the fastening piece while being extended in a transverse direction of the fastening piece.

The container can be locked into a stack of containers. A container cover locks onto the top of a container base to define a sealed area for storage. Additionally, the bottom of a second container base can be locked onto the top of the cover of a first container. In this fashion, when closed containers are stacked, they form a locked stack that is more structurally rigid and therefore less precarious than a traditional, non-locked container stack. When not in use, the bases can be formed into a nested stack, and their covers can be locked together to form a locked cover stack. The locked cover stack can be locked to either the top or bottom of the nested base stack to form a rigid stack. In some embodiments, a cover can be turned upside down and its bottom face locked onto the bottom face of a base.

An improved container for storing, dispensing and handling viscous and semi-viscous fluids such as paint and the like, having novel spout and other design features that enable substantially dripless dispensing and improved handling and storage

A variety of closures are provided for use with a drink cup or other container wherein the closures provide a compartment for receiving a digital media disk or other merchandise. Examples include various closures formed of inner and outer members connected by a hinge with the inner and outer members forming a compartment for closely receiving a digital media disk. Other examples include a closure having a single lid portion with a retaining mechanism for retaining a digital media disk to a top surface of the lid. The retaining mechanism includes, for example, elastic retaining bands or resilient tabs. In another example, the closure provides a curved compartment for receiving a booklet wherein a closure for the compartment includes snap-fit members for attaching the compartment closure to other portions of the container lid. Still other embodiments are provided for enclosing toys or the like including one embodiment wherein the closure is configured to retain both a compressible ball and a backboard. In use, after any beverage within the cup is consumed, the backboard is removed from the closure and mounted to a rim of the cup for providing a basketball hoop-like arrangement for use with the compressible ball. Numerous other embodiments are described.
