A packaging assembly includes a container body defining an interior for housing a product and an opening leading to the interior. The assembly further includes a cap that moves with respect to the container body to move the assembly between a closed position in which the cap covers the opening, and an opened position in which the opening is exposed. A first seal (40) is defined between the container body and the cap. The first seal includes a protrusion (42) formed on one of the container body about the opening or the cap, and a groove (44) formed on the other of the container body about the opening or the cap. The protrusion is received by the groove when the assembly is in the closed position, such that contact is maintained in a sealing relationship around the opening between the groove and the protrusion.

A storage container preferably includes a container portion and a lid. The container portion preferably includes a bottom wall, a vertical peripheral wall and a female peripheral sealing cavity. The vertical peripheral wall extends upward from an outer perimeter of the bottom wall. The female peripheral sealing cavity extends around an entire perimeter of the vertical peripheral wall. The lid includes a top wall and a male peripheral sealing projection. The male peripheral sealing projection includes a partially curved cross section, which is sized to be sealingly received by the female peripheral sealing cavity. A top inner perimeter of the male peripheral sealing projection extends from an outer perimeter of the top wall. The male peripheral sealing projection extends around an entire perimeter of the top wall. The shape of the lid and storage portion preferably include a substantially rectangular shape with four curved corners.

A buckle joint structure has a first body, a second body and a buckle module with a cross section of a C-shape. A first flange of the first body is fixed or buckled to a second flange of the second body via the buckle module with the cross section of the C-shape. When assembling, merely a sliding manner is required to make the first flange of the first body and the second flange of the second body buckled to the buckle module. When detaching, merely a sliding manner is required to withdraw the buckle module away from the first body and the second body. Thus, the buckle joint structure is easily assembled or detached without an extra tool or help of another person.

The present invention relates to a barrel lid, such as a wood wine barrel lid, that inhibits and withstands warping and/or deformation. In one embodiment, the anti-warping wine barrel head comprises a plurality of adjacent slats, a plurality of staves where at least one stave disposed between each pair of adjacent slats, a plurality of grooves disposed on a top and/or bottom surface of the barrel head where each groove is oriented at an angle with respect to the plurality of slats, and a plurality of rods disposed in the plurality of top and/or bottom surface grooves where at least one rod is disposed in each of the plurality of top and/or bottom surface grooves. In some embodiments, staves are double flanged or rectangular, and rods have a half-round cross-section or triangular cross-section. In other embodiments, a gasket may span the periphery of the barrel lid, for example, along a lip thereof. In some embodiments, a locking ring is utilized to secure wine barrel lid to the container or drum.

A modular robot system which may be configured to accommodate packages of varying sizes is provided. The modular robot may include a base have omni-directional wheels and cameras and sensors, one or more modular containers, and a lid, which may be releasably linked together to form a small, medium or larger units. The base, one or more modular containers, and the lid may be electrically linked to provide information to be used in a number of ways. For example, the electrical link may allow two or more modular robots to communicate with each other, enable external displays of multiple modules to act as one large unit, control the motion of the drawers, e.g., allowing them to open/close, and allow the processor(s) in the lid to communicate with the drive system of the omni-directional wheels. A set of alternating interlocking rails and tracks on corresponding surfaces enable the various layers of the modular robot to interlock with one another. Interlocking of multiple modular containers may be established by sliding one surface over the other. These sections may be used to create modular robots of varying sizes.

Provided is a food container which includes a box body with an opening and a box cover; the box body includes a box bottom and a box wall; a top edge of the box wall extends toward the outer side of the box body to form a first connecting strip; the first connecting strip is provided with a groove in the middle; the box cover includes a cover plate and a side wall; a top edge of the side wall extends toward the outer side of the box cover to form a second connecting strip; the middle of the second connecting strip protrudes to form a convex rib; when the box cover covers the opening of the box body, the convex rib of the box cover is embedded into the groove of the box body to form a seal structure. The food container is good at sealing performance.

An accessory includes a container band having an inner surface configured to conform to and engage an outer surface of a container, and an arm member connected to and extending from the container band. The arm member selectively engages a lid of the container. The arm member includes an arm body, a spout plug extending from the arm body, where the spout plug is configured to selectively seal a spout opening in the lid of the container, and a vent cover extending from the arm body, where the vent cover is configured to selectively seal a vent opening of the lid of the container.

A rim assembly for a container comprises a frame member (346) having a perimeter corresponding in shape to an opening of a container such that, in use, the frame member is received within the opening and extends around an interior surface of a side wall of the container; a plurality of securing tabs (394) hingedly connected to the frame member (346), each tab (394) including an engagement member (396); sealing means configured for repeated sealing engagement with a lid of the container; and retaining means (399), wherein each of the securing tabs is movable between a first position in which the engagement member is disengaged from an aperture (317) in the container side wall and a second position in which the engagement member (396) is engaged with one of the apertures (317) in the side wall, and wherein the retaining means is configured to retain the securing tabs in the second position such that the rim assembly is secured to the container around a top edge of the side wall.

The assembly 100 includes a container 102 and a lid 104. The container 102 includes a main body 110 and a container rim 120 surrounding the main body 110. The container rim 120 has an outer peripheral horizontal top surface 122 and an inner peripheral horizontal top surface 124 vertically above the outer peripheral horizontal top surface. The lid 104 includes a ring-shaped lid frame 130 and a membrane 132 that is attached over a top surface of the lid frame 130 and seals with inner peripheral horizontal top surface.
