A foldable tote box enables a content thereof to be visually checked under a state in which a lid is closed. The foldable tote box includes a box body including: a square or rectangular bottom surface part; front and rear side wall parts and right and left side wall parts corresponding to respective sides; a lid extending from an upper edge of the rear side wall part; and a reinforcement plate configured to reinforce the bottom surface part. The reinforcement plate is pivotably mounted on a lower edge of the front side wall part or the rear side wall part. The right and left side wall parts are inwardly foldable when a center portion of the bottom surface part is pulled up. Each of the side wall parts is formed of a frame member, and a sheet material including a transparent portion is supported by the frame member.

Sterilization packaging systems with features for sealing a volume against an ingress of contaminants are provided. Such features include a sealing assembly including a gasket and a sheet of filter material. The sealing assembly seals a lid to a seal rim of a base. The gasket has an upper surface, outer edge, and inner edge. The upper surface of the gasket comprises a first row of alternating protrusions and indentations and a second row of alternating protrusions and indentations that define a channel therebetween. The sheet of filter material extends from an inner edge of the gasket. The gasket completely surrounds the sheet of filter material, wherein the indentations and channel facilitate delivery of a sterilization agent through the filter material. A sterilization assembly including a lid having a plurality of protrusions in its upper surface in conjunction with a gasket having a smooth upper surface is also provided.

The invention consists of a cooler system entailing a foamed polymer body coated in a layer of elastomer and secured with a strap system. The body of the cooler consists of a base which serves as a container for beverages or other products as well as a lid, designed to fit the base such that it can only be removed by lifting upward. The foamed polymer provides insulation and structure while the elastomer coating and the straps provide increased durability and functionality. The body of the cooler contains grooves in which the straps are housed in order to secure the lid. The strap system also provides a means for carrying the invention as an anchoring place for handles. The resulting cooler system is lightweight and durable as well as inexpensive to construct.

A thermal container includes a cover and a main body. The cover is opened and closed relative to the main body through an opening-closing assembly. The cover is formed with a sealing protrusion extending toward the main body. The main body is formed with an annular retaining wall extending from an upper portion of an inner wall of the main body. A sealing ring is provided at the mating portion between the cover and the main body. The thermal container realizes the sealing through the sealing protrusion and the retaining wall, and the sealing ring is provided to further enhance the airtightness, preventing the gas or liquid from leaking out from the gap of the opening-opening assembly, and improving the thermal insulation performance of the container.

Seal integrity indicators for sterilization containers are provided. For example, a seal indicator may indicate whether the container is sufficiently sealed to prevent an ingress of contaminants into the container. If the container is sufficiently sealed, the seal indicator is visible, but if not, the seal indicator is not visible. Thus, the seal indicator undergoes a change in state when the sterilization container transitions from unsealed to sealed, or vice versa, such that a user may ascertain whether the container is properly sealed to maintain the container's sterility. An exemplary seal indicator includes an invertible projection formed with the container gasket that is not visible from outside the container until inverted, due to force applied by the lid, to extend through an opening in the container body. Closure mechanisms for sterilization containers also are provided.

A storage unit comprises sidewalls and a base. A lid is connected to one of the sidewalls and movable between a first open position and a second closed position. The sidewalls and base defined an inner space. The storage unit may include integrated wheels at or near the confluence of the base and at least one of the sidewalls for rolling the storage unit over a surface. Organization components are provided for selective and releasable placement within the inner space for compartmentalizing the inner space into a desired configuration.

An assembly comprising a bucket body having vertical side walls wherein the vertical side walls extend upwards from a closed bottom base. A handle may be connected to the vertical side walls, and one or more ergonomically designed feet may be detachably connected to and extend beyond a bottom surface of the bottom base. Disclosed embodiments may provide an ergonomic grip portion integrally formed with the handle. The handle may be connected to the bucket body via a twist-lock connection assembly.

A foot assembly includes a block retainer and a non-skid block. The block retainer is configured to be positioned at least proximate to an edge between a bottom surface and a side surface of a structure. The block retainer includes a planar portion, an angled portion, and a front surface. The planar portion has an interior surface configured to contact the bottom surface. The angled portion is diposed at an angle from the planar portion and includes an interior surface configured to contact an angled contact surface of the structure. The front surface includes a first dynamic coefficient of friction (DCOF). The non-skid block is connected to the planar portion and includes an exterior portion extending from the front surface away from the structure and includes a second DCOF greater than the first DCOF.

The invention discloses an airtight thermal insulation with a large opening therein, comprising a base, a tableware box, a thermal insulation body, a zipper enclosure, an iron wire frame and a strap, wherein the side of the base has the tableware box, the top thereof has the body; the side of the body has an outer pocket, the left and right sides thereof have a handle above the pocket, the interior thereof has the inner lining; two sides of the inner lining top have a zipper tail strap extendedly, the periphery thereof has the velcro; the body top edge has a zipper enclosure; two sides of the enclosure have a side patch top, the enclosure is internally embedded with the iron wire frame comprising left and right ones. The overall structure is simple, the sealing effect is good, the large opening effect is achieved and it has certain promotion value.
