The box body includes a plurality of side walls respectively including a plurality of outer and inner portions, an annular groove formed on the inner portions, and an annular protrusion portion. Each outer portion has a level difference with the corresponding inner portion. Any two adjacent ones of the side walls form a corner portion. An outer surface of each corner portion forms a sharp corner. The annular groove is arc-shaped at a position corresponding to each corner portion. Each corner portion includes a hollowed-out area. The cover body includes a main body in a polygonal shape with sharp corners, an annular protrusion portion protruding from the main body, and an annular groove. The annular protrusion portions extend into the annular grooves, so that the cover body is sealedly joined to the box body.

A storage box that includes a container, a lid and a circular seal. The lid includes a bottom part, a top part, a bottom cog-wheel part with sloping teeth, a spring, a snap part with stopping members, two lever bodies, a top cog-wheel with sloping pushing teeth, and a push button handle. The bottom part includes an indent for containing the spring and oriented holes for the snap part snaps. The top part includes the top button handle, the top cog-wheel part, the two lever bodies, and the bottom cog-wheel. The spring is positioned inside the indentation, the top part is assembled on the bottom part, the bottom cog-wheel is connected to the top cog-wheel in a way that enables a rotational movement between them and disables a relative vertical movement. The lid is in a retracted close position or in an extended open position.

A dust-excluding carrier for product storage comprises a housing cavity and dust-excluding isolation members. The dust-excluding isolation member comprises a first main body, the first main body is provided with a first opening; the material tray and the dust-excluding isolation member are detachably connected. The material tray comprises a second main body with a second opening. The first main body and the second main body may be snap-fitted together and apart, so the first opening is covered by the second body and the second opening covered by the first body.

In one embodiment, a lid structure with latches is configured for sealing use with container vessels of different materials having differing manufacturing dimensional tolerances, such plastic vessels and glass vessels. Another feature of a lid and vessel combination is the provision of a lid receptacle feature, configured to capture the base of a vessel in a stacking arrangement, without utilization of special features on the vessel base. A method of merchandising lids and vessels is described, wherein a lid is provided for separate purchase, a plurality of vessels of different materials is provided for separate purchase which are configured to match to the lid.

A beverage and snack consumption enhancing lid. The lid includes at least one of a snack receiving receptacle and at least one beverage flavoring capsule receptacle. A snack ejector is installed or integrated into the snack receiving receptacle. A snack is packaged within the snack receiving receptacle and retained therein by a snack cover. A beverage flavoring capsule is placed in each at least one beverage flavoring capsule receptacle and retained therein by a seal. The snack cover can multi-function as the capsule seal. The snack ejector would raise the snack from the snack receptacle when the cover is opened. The capsule can be compressed against a piercing element integrated into the capsule receptacle. Flavoring from within the capsule would be dispensed into the beverage to enhance the beverage flavor.

A substantially moisture tight container and lid assembly for storing and packaging moisture-sensitive items comprising an assembly with a container and a lid, the lid is attached by a hinge to an upper housing portion of the container, the lid includes a lip seal member that depends downwardly from the lid, the lip seal member is configured to abut at least a portion of the interior side of the container when the lid is in the closed position resulting in a substantially moisture tight seal between the lid and the lid, and the container assembly further comprising a base portion and an upper housing portion, the upper housing portion is capable of being snap-fit into the base portion by employing a lip seal mechanism to form a substantially moisture-tight seal.

A lid-container assembly made of synthetic plastic material suitable for the transportation and storage of hazardous materials in conformity to the UN standard. The container includes a bottom and a substantially cylindrical or cone trunk side wall having an upper edge that bounds an access opening. The container is provided with a first external annular strip provided with a first circular rib and with at least one second circular rib for snap fitting of the lid. The lid includes a central part and a peripheral wall that conforms to the side wall of the container and further includes a second external annular strip that releasably engages the corresponding external annular strip of the container. The second external annular strip has an upper annular element that connects to the peripheral wall by an upturned U-shaped upper annular channel, and includes a lower annular element inserted into a lower annular channel in the form of an upwards pointing U, and an intermediate annular element for tear opening. The lower annular element of the second external strip includes a circular rib that engages a corresponding internal rib of the lower annular channel of the first external strip. The lid-container assembly further includes a first interference sealing zone between opposite surfaces of the side wall of the container and of the peripheral wall of the lid, a second contact sealing zone between the upper edge of the side wall of the container and the interior of the upper annular channel, and at least one third contact sealing zone between opposite engaging ribs of the first and second external annular strips.

A sip lid for a children's drinking vessel includes a spout component having a first end region and a second end region opposite to the first end region. The spout component is shaped and sized to be received within a child's mouth. The first end region comprises one or more openings configured to allow liquid to be extracted through the spout component when the child is applying suction to the spout component. The sip lid also includes a base component extending from the second end region of the spout component and surrounding the spout component. The base component is made from an elastic material configured to allow the base component to stretch over differently sized mouths of drinking vessels to form a liquid-tight seal between the base component and the drinking vessels.

Stackable lids for a container each include a top surface facing generally in a first direction and a bottom surface opposite the top surface and facing generally in a second direction. Pivotable wing portions extend from each side edge of the lid and each pivotable wing portion is joined to its respective side edge by a hinge. The wing portions are moveable between engaged and disengaged positions, and an inner surface of each wing includes a tab member configured for detent engagement with a rim of the container. The lid also includes corner portions extending between the side edges. Each corner portion includes a skirt portion extending generally in the second direction. Each corner portion also defines a recessed shoulder configured to receive the skirt portion of another when the lids are stacked.

A substantially moisture tight container and lid assembly for storing and packaging moisture-sensitive items comprising an assembly with a container and a lid, the lid is attached by a hinge to an upper housing portion of the container, the lid includes a lip seal member that depends downwardly from the lid, the lip seal member is configured to abut at least a portion of the interior side of the container when the lid is in the closed position resulting in a substantially moisture tight seal between the lid and the lid, and the container assembly further comprising a base portion and an upper housing portion, the upper housing portion is capable of being snap-fit into the base portion by employing a lip seal mechanism to form a substantially moisture-tight seal.
